Definitions
- the invention relates to a level monitoring device for a device for storing several pumpable detergent or dishwashing agents in each container and for the automatic metered addition of detergent required in the washing or rinsing process in the tub of a washing machine or dishwasher, the device being a control device for has an operating panel with a display device for predetermined container filling states and sensor devices in or on the containers for these filling states.
- Such a fill level monitoring device is known from DE-OS 33 02 925.
- the remaining filling quantity provided therein is very large for a certain number of (thought was the number 10) dosing processes.
- the operator can rely on the automatic switchover to manual dosing provided there, so that they do not press on Lich enough to procure the running out of active ingredient and to refill the emptying container. Soon the necessary refill is forgotten and the container is empty, so that the operator may be forced to uncomfortable manual dosing of packaged detergent because the required active ingredient was not procured in time.
- the invention has for its object to clearly emphasize the need to replenish stocks of washing or washing-up liquid stocks by simple measures.
- this object is achieved in that the container filling states correspond to a residual filling quantity in each container, which is sufficient for a maximum of five doses of the same active ingredient, each with a maximum of 120 ml.
- the maximum filling volumes of the storage containers are limited on the one hand by the fact that the highest possible number of automatically metered additions should be possible without the storage container having to be refilled. A refill interval of four months with approx. 50 doses is sought in this period.
- the maximum filling volume of each container is limited by the fact that there is no arbitrarily large space for installing such storage containers.
- the remaining filling volume when the deficiency report is triggered has a volume of 300 ml to 600 ml, five 60 ml cans (or a smaller number of larger quantities) or five 120 ml cans (largest single dose assumed) can be removed.
- a single optical signal is sufficient if the containers are each assigned a hydromechanical monitoring device.
- a hydromechanical monitoring device can be formed, for example, by a pull-out dipstick in each container.
- the display device contains one lamp per container and, if appropriate, an acoustic signal device for all containers.
- An acoustic signal device e.g. a horn
- the fill level monitoring device for a device in which the containers have a volume which is greater than the remaining fill quantity than that of a transport container provided to supplement the supply can advantageously be further developed in that the display device has a further lamp for each container Containers filled state that has occurred after removing a quantity corresponding to the volume of the transport container.
- this additional display device - apart from the additional lamp per container - can be accomplished without any additional material expenditure in that for measuring the amount withdrawn in the (anyway existing, modernly equipped with a microcomputer) control device one for each dose of active substance removed from one of the containers number of dosing units corresponding to the dosing quantity is registered and when a certain sum of dosing units is reached the display device is prepared for signaling by the further light.
- This further development of the invention can be implemented in a simple manner by expanding the software of an electronic control device. Additional level sensors in the containers are therefore unnecessary.
- a particular advantage results from the fact that in a further development of the invention the prepared signaling can be triggered by the additional lamp together with the optical signaling for the remaining filling state of any container.
- the advantage of this is the operation. If the signal for the residual filling status of any container is triggered, then - if another of the remaining containers has already been emptied according to the volume of a transport container - an indication can also be given so that the operator has the opportunity to recognize from it that this container can be refilled in the same operation through the full contents of a transport container. All other storage containers could also be refilled. However, if their withdrawal quantities are smaller than the volume of a transport container, a residual quantity would still be left in the respective transport container after refilling.
- the operator would then be forced to pick up this partially emptied transport container.
- the operator could fill the entire filling quantity of a transport container into the storage container whose additional indicator light had signaled the partial emptying.
- the emptied transport container can then be thrown away and does not take up any space in the operator's household.
- the invention can be advantageously further developed in that an automatically triggered signaling can be deleted by actuating the handle in the sense of manual dosing.
- the triggered signaling can be both optical and acoustic, but the signaling to be deleted can only be the acoustic signal. Then the operator remains visually informed of an almost empty container, but the annoying acoustic signal can be deleted for the individual case of manual dosing.
- the control of the supply and metering device is advantageously designed in such a way that a manual dose selection is automatically deleted after the washing or rinsing process has expired, so that the environmental and user-oriented advantages of automatic metering are used as often as possible.
- an advantageous development of the invention can consist in that all signals can be canceled by the return of the sensor device which triggers the signaling to its idle state.
- FIG. 1 shows the schematic arrangement of the storage containers BV for heavy-duty detergents, BF for mild detergents, BB for bleach and BW for fabric softener in the storage and dosing device.
- the larger containers have a volume that is approximately twice as large as the volume of a transport container for detergent or dishwashing detergent substances, not shown here.
- the large containers have a volume of 6.6 liters
- the small storage container BW has a volume of 4.3 liters.
- a marking TF is applied corresponding to a removal volume that can be accommodated in the upper part of the container, equal to the volume of a transport container.
- RF which indicates the level of the remaining filling quantity RFM in the container.
- the switching point of a sensor device S lies at the level of this marking RF.
- the sensor device sends a signal which triggers or prepares the signal to the control device (not shown).
- This signaling can be formed, for example, from a flashing light-emitting diode in the optical area and from a piezoceramic oscillator in the acoustic area.
- the BW container for storing fabric softener has a total volume of, for example, 4.3 liters. Once its remaining filling quantity has been reached (level RF), a maximum of five washing processes, each with a softener dose of 60 ml, can be added.
- the remaining filling quantities are set up so that when the signaling device S triggers, two full transport container volumes can be filled into the containers BV, BF and BB, while the storage container BW above the residual filling level RF is slightly more than the volume of a transport container sums up.
- the remaining filling amounts are about 1/25 to about 1/6 of the total volumes of the respective containers.
- the remaining filling quantities in the large containers BV, BF and BB are 600 ml corresponding to 1/11 of the total filling quantity of each large container and 300 ml in the small container BW corresponding to approx. 1/14 of the total filling volume.
- handles H1 for switching the supply and dosing device on and off, HH for entering the water hardness to be taken into account, HD for selecting the dosage (automatic or manual dosing) and HW for selecting the softener dosage are arranged.
- Display elements LED are assigned to the operating handles HH, HD and HW to make their setting visible. They are labeled accordingly.
- Signal lights SVR for displaying the remaining filling quantity of heavy-duty detergent, SFR for displaying the remaining filling quantity of mild detergent, SBR for displaying the remaining filling quantity of bleach and SWR for displaying the remaining filling quantity of fabric softener are arranged above. Furthermore, signal lights for the display of a removal in the amount of the volume of a transport container are arranged; they are called SVTF, SBTF and SWTF. In the example shown it is indicated that the lights SVR, SVTF and SWTF light up.
- the operator can empty the contents of two transport containers of heavy-duty detergent into the storage container BV, the sensor device of which then also clears all the signal lights - including the signal light SWTF.
- the control device can also be designed in such a way that the acoustic signaling AS is only switched on after a certain number of dosing processes from reaching the remaining filling quantity.
- the control device is equipped with a counter, which can each add up a number of dosing units, which are integral parts of the actual dosing quantity. After counting a number of dosing units, which should be less than that of the total remaining filling quantity RFM, the acoustic signal is switched on.
- An advantageous alternative can also be seen in the fact that an acoustic signal already triggered when the reserve level RF is reached is amplified after the aforementioned upper limit has been reached and / or cannot be erased until the emptied container is filled.
- the number of dosing units that corresponds to the total remaining filling quantity is also known and forms the upper limit for the possible dosing from the remaining filling quantity. As soon as this upper limit is reached, the control device can automatically switch from automatic to manual dosing and, if necessary, switch off the acoustic signal. However, the acoustic signal should always be switched on automatically as long as the emptied container has not been refilled and automatic dosing is requested.
- a further reinforcement of the "educational effect" mentioned at the outset can be achieved in that no washing or rinsing process can be started at all when the above-mentioned upper limit is reached.
Abstract
Description
Die Erfindung betrifft eine Füllstandsüberwachungseinrichtung für ein Gerät zum Bevorraten von mehreren pumpbaren Wasch- oder Spülmittel-Wirkstoffen in je einem Behälter und zur automatischen dosierten Zugabe beim Wasch- oder Spülprozeß benötigten Wirkstoffdosen in den Laugenbehälter einer Wasch- oder Spülmaschine, wobei das Gerät eine Steuereinrichtung für eine Bedienblende mit einer Anzeigeeinrichtung für vorbestimmte Behälterfüllzustände und Sensoreinrichtungen in oder an den Behältern für diese Füllzustände aufweist.The invention relates to a level monitoring device for a device for storing several pumpable detergent or dishwashing agents in each container and for the automatic metered addition of detergent required in the washing or rinsing process in the tub of a washing machine or dishwasher, the device being a control device for has an operating panel with a display device for predetermined container filling states and sensor devices in or on the containers for these filling states.
Eine derartige Füllstandsüberwachungseinrichtung ist durch die DE-OS 33 02 925 bekannt. Einerseits ist die darin noch vorgesehene Restfüllmenge für eine gewisse Zahl von (gedacht war an die Zahl 10) Dosiervorgängen sehr groß. Andererseits kann sich die Bedienungsperson nach dem Melden des Mangels auf die dort vorgesehene automatische Umschaltung auf die Handdosierung verlassen, so daß sie nicht nachdrück lich genug zur Neubeschaffung des zur Neige gehenden Wirkstoffs und zum Nachfüllen des sich entleerenden Behälters veranlaßt wird. Bald ist die erforderliche Nachfüllung vergessen und der Behälter leer, so daß die Bedienungsperson gegebenenfalls zur unbequemen Handdosierung von konfektioniertem Waschmittel gezwungen ist, weil nicht rechtzeitig der erforderliche Wirkstoff neu beschafft wurde.Such a fill level monitoring device is known from DE-OS 33 02 925. On the one hand, the remaining filling quantity provided therein is very large for a certain number of (thought was the number 10) dosing processes. On the other hand, after reporting the defect, the operator can rely on the automatic switchover to manual dosing provided there, so that they do not press on Lich enough to procure the running out of active ingredient and to refill the emptying container. Soon the necessary refill is forgotten and the container is empty, so that the operator may be forced to uncomfortable manual dosing of packaged detergent because the required active ingredient was not procured in time.
Der Erfindung liegt die Aufgabe zugrunde, den Zwang zum Ergänzen des Vorrats von zur Neige gehenden Wasch- oder Spülmittel-Vorräten durch einfache Maßnahmen deutlich hervorzuheben.The invention has for its object to clearly emphasize the need to replenish stocks of washing or washing-up liquid stocks by simple measures.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Behälterfüllzustände je einer Restfüllmenge in jedem Behälter entsprechen, die für höchstens fünf Dosen desselben Wirkstoffs mit jeweils höchstens 120 ml ausreicht.According to the invention, this object is achieved in that the container filling states correspond to a residual filling quantity in each container, which is sufficient for a maximum of five doses of the same active ingredient, each with a maximum of 120 ml.
Die maximalen Füllvolumina der Vorratsbehälter sind nach unten einerseits dadurch beschränkt, daß eine möglichst hohe Anzahl von automatisch dosierbaren Zugaben möglich sein soll, ohne daß der Vorratsbehälter erneut aufgefüllt werden muß. Dabei wird ein Nachfüll-Intervall von vier Monaten bei ca. 50 Dosierungen in dieser Zeitspanne angestrebt. Nach oben begrenzt sich das maximale Füllvolumen jedes Behälters dadurch, daß kein beliebig großer Raum zur Aufstellung derartiger Vorratsbehälter vorhanden ist. Aus dem Stand der Technik sind beistellbare Vorrats- und Dosiergeräte bekannt, die eine Breite von beispielsweise 15 cm haben. Die beiden übrigen Maße (Tiefe = maximal 60 cm und Höhe = maximal 85 cm) ergeben sich durch die Normmaße von schrankförmigen Haushalt-Großgeräten. In einem derartigen Vorrats- und Dosiergerät sind - setzt man Vorratsbehälter für vier unterschiedliche Wirkstoffe voraus - kaum mehr als maximal 6,6 Liter Füllvolumen je Behälter möglich. Bei Unterbringung von Vorratsbehältern in einem normgerechten schrankförmigen Haushalt-Großgerät selbst kann das maximale Füllvolumen eines Behälters sicher nicht größer sein als 3,3 Liter.The maximum filling volumes of the storage containers are limited on the one hand by the fact that the highest possible number of automatically metered additions should be possible without the storage container having to be refilled. A refill interval of four months with approx. 50 doses is sought in this period. The maximum filling volume of each container is limited by the fact that there is no arbitrarily large space for installing such storage containers. Provided storage and metering devices are known from the prior art, which have a width of 15 cm, for example. The other two dimensions (depth = maximum 60 cm and height = maximum 85 cm) result from the standard dimensions of large cabinet-shaped household appliances. In such a storage and dosing device - if storage containers for four different active ingredients are required - hardly more than a maximum of 6.6 liters filling volume per container is possible. If storage containers are accommodated in a standard, large, cupboard-shaped household appliance itself, the maximum filling volume of a container cannot be greater than 3.3 liters.
Wenn die beim Auslösen der Mangelmeldung noch vorhandene Restfüllmenge ein Volumen von 300 ml bis 600 ml hat, sind noch fünf Dosen à 60 ml (oder eine kleinere Anzahl mit jeweils größerer Menge) bzw. fünf Dosen à 120 ml (größte angenommene Einzeldosis) entnehmbar.If the remaining filling volume when the deficiency report is triggered has a volume of 300 ml to 600 ml, five 60 ml cans (or a smaller number of larger quantities) or five 120 ml cans (largest single dose assumed) can be removed.
Bei einer so geringen Zahl von noch möglichen automatischen Dosiervorgängen nach der Anzeige der erreichten Restfüllmenge muß sich die Bedienungsperson veranlaßt sehen, für eine sofortige Ergänzung des Vorrats zu sorgen. Dies wirkt indirekt als Erziehungsmaßnahme, weil eine in dieser Beziehung nachlässige Bedienungsperson kurze Zeit später mit dem Erfordernis der unbequemen Handdosierung "bestraft" wird.With such a small number of still possible automatic dosing processes after the display of the remaining filling quantity reached, the operator must see himself prompted to immediately replenish the supply. This acts indirectly as an educational measure, because an operator who is negligent in this regard is "punished" shortly afterwards with the requirement of inconvenient manual dosing.
Zwar genügt für den Hinweis auf einen fast leeren Vorratsbehälter eine einzige optische Signalgabe, wenn den Behältern je eine hydromechanische Überwachungsvorrichtung zugeordnet ist. Eine solche Vorrichtung kann beispielsweise durch einen herausziehbaren Peilstab in jedem Behälter gebildet sein. Zur Erleichterung der Auffindung eines fast leeren Behälters ist es aber von besonderem Vorteil, wenn die Anzeigeeinrichtung eine Leuchte je Behälter und ggf. eine akustische Signaleinrichtung für alle Behälter enthält. Eine akustische Signaleinrichtung (z.B. eine Hupe) für alle Behälter macht die Bedienungsperson auf einen fast leeren Behälter aufmerksam. Aufschluß darüber, welcher Behälter nachzufüllen ist, gibt dann ein Blick auf die eingeschaltete Anzeigeleuchte.To indicate an almost empty storage container, a single optical signal is sufficient if the containers are each assigned a hydromechanical monitoring device. Such a device can be formed, for example, by a pull-out dipstick in each container. To make it easier to find an almost empty container, however, it is particularly advantageous if the display device contains one lamp per container and, if appropriate, an acoustic signal device for all containers. An acoustic signal device (e.g. a horn) for all containers draws the operator's attention to an almost empty container. A glance at the indicator light that is switched on then provides information about which container has to be refilled.
Die erfindungsgemäße Füllstandsüberwachungseinrichtung für ein Gerät, bei dem die Behälter ein Volumen haben, das um mehr als die Restfüllmenge größer ist als dasjenige eines für die Ergänzung des Vorrats vorgesehenen Transportbehälters, kann vorteilhafterweise dadurch weitergebildet werden, daß die Anzeigeeinrichtung je Behälter eine weitere Leuchte für einen Behälterfüllzustand enthält, der sich nach der Entnahme einer dem Volumen des Transportbehälters entsprechenden Menge eingestellt hat. Diese Weiterbildung kommt zwar dem Stand der Technik, durch den es bekannt war, eine größere Restfüllmenge bereits zu signalisieren, wieder näher, jedoch unter dem Aspekt, daß eine sich hierauf gründende Nachlässigkeit der Bedienungsperson nicht bereits zum Vergessen führen kann, weil eine "gefährlich" geringe Restfüllmenge später ebenfalls noch zur Anzeige gelangt.The fill level monitoring device according to the invention for a device in which the containers have a volume which is greater than the remaining fill quantity than that of a transport container provided to supplement the supply can advantageously be further developed in that the display device has a further lamp for each container Containers filled state that has occurred after removing a quantity corresponding to the volume of the transport container. This further development comes closer to the state of the art, by which it was known to signal a larger remaining filling quantity, but from the point of view that a negligence of the operator based on this cannot already lead to forgetting, because a "dangerous" small remaining filling quantity will also be displayed later.
In technischer Hinsicht kann diese zusätzliche Anzeigeeinrichtung - abgesehen von der weiteren Leuchte je Behälter - ohne weiteren Materialaufwand dadurch bewerkstelligt werden, daß zur Bemessung der Entnahmemenge in der (ohnehin vorhandenen, modernerweise mit einem Microcomputer ausgestatteten) Steuereinrichtung für jede aus einem der Behälter entnommene Wirkstoffdosis eine der Dosiermenge entsprechende Anzahl von Dosiereinheiten registriert und beim Erreichen einer bestimmten Summe von Dosiereinheiten die Anzeigeeinrichtung zur Signalgabe durch die weitere Leuchte vorbereitet wird. Die Realisierung dieser Weiterbildung der Erfindung kann auf einfache Weise durch Erweiterung der Software einer elektronischen Steuereinrichtung bewerkstelligt werden. Weitere Niveausensoren in den Behältern erübrigen sich daher.From a technical point of view, this additional display device - apart from the additional lamp per container - can be accomplished without any additional material expenditure in that for measuring the amount withdrawn in the (anyway existing, modernly equipped with a microcomputer) control device one for each dose of active substance removed from one of the containers number of dosing units corresponding to the dosing quantity is registered and when a certain sum of dosing units is reached the display device is prepared for signaling by the further light. This further development of the invention can be implemented in a simple manner by expanding the software of an electronic control device. Additional level sensors in the containers are therefore unnecessary.
Ein besonderer Vorteil ergibt sich daraus, daß in einer Weiterbildung der Erfindung die vorbereitete Signalgabe durch die weitere Leuchte zusammen mit der optischen Signalgabe für den Restfüllzustand eines beliebigen Behälters auslösbar ist. Der Vorteil hierbei ist in der Bedienung zu sehen. Wird nämlich das Signal für den Restfüllzustand eines beliebigen Behälters ausgelöst, dann kann - sofern ein anderer von den restlichen Behältern bereits um die Entnahmemenge entsprechend dem Volumen eines Transportbehälters geleert worden ist - hierfür ebenfalls eine Anzeige erfolgen, damit die Bedienungsperson Gelegenheit hat, hieraus zu erkennen, daß dieser Behälter sinnvollerweise im gleichen Arbeitsgang durch den vollen Inhalt eines Transportbehälters nachfüllbar ist. Zwar könnten alle anderen Vorratsbehälter ebenfalls wieder aufgefüllt werden. Sind deren Entnahmemengen jedoch kleiner als das Volumen eines Transportbehälters, dann würde nach dem Nachfüllen im jeweiligen Transportbehälter noch eine Restmenge übrig bleiben. Die Bedienungsperson wäre dann gezwungen, diesen teilweise entleeren Transportbehälter aufzuheben. Im Falle der vorgenannten Weiterbildung der Erfindung könnte die Bedienungsperson aber die gesamten Füllmenge eines Transportbehälters in denjenigen Vorratsbehälter um füllen, dessen weitere Anzeigeleuchte die teilweise Entleerung signalisiert hatte. Der entleerte Transportbehälter kann dann weggeworfen werden und nimmt im Haushalt der Bedienungsperson keinen Raum ein.A particular advantage results from the fact that in a further development of the invention the prepared signaling can be triggered by the additional lamp together with the optical signaling for the remaining filling state of any container. The advantage of this is the operation. If the signal for the residual filling status of any container is triggered, then - if another of the remaining containers has already been emptied according to the volume of a transport container - an indication can also be given so that the operator has the opportunity to recognize from it that this container can be refilled in the same operation through the full contents of a transport container. All other storage containers could also be refilled. However, if their withdrawal quantities are smaller than the volume of a transport container, a residual quantity would still be left in the respective transport container after refilling. The operator would then be forced to pick up this partially emptied transport container. In the case of the aforementioned development of the invention, the operator could fill the entire filling quantity of a transport container into the storage container whose additional indicator light had signaled the partial emptying. The emptied transport container can then be thrown away and does not take up any space in the operator's household.
Bei einer Füllstandsüberwachungseinrichtung für ein Gerät, bei dem die Bedienblende eine Handhabe zum Auswählen einer automatischen Dosierung von SystemWasch- oder -Spülmitteln oder einer Handdosierung von konfektionierten Wasch- oder Spülmitteln in je eine zum Bereitstellen von Einzeldosen vorgesehene Kammer der Wasch- oder Spülmaschine aufweist, kann die Erfindung dadurch vorteilhaft weitergebildet werden, daß eine automatisch ausgelöste Signalgabe durch eine Betätigung der Handhabe im Sinne der Handdosierung löschbar ist. Dabei kann die ausgelöste Signalgabe sowohl optisch als auch akustisch vorliegen, die zu löschende Signalgabe aber lediglich die akustische sein. Dann bleibt der Bedienungsperson der optische Hinweis auf einen fast leeren Behälter erhalten, die lästige akustische Signalgabe kann jedoch für den Einzelfall der Handdosierung gelöscht werden. Vorteilhafterweise ist die Steuerung des Vorrats- und Dosiergerätes so ausgelegt, daß eine Handdosierungs-Wahl nach abgelaufenem Wasch- oder Spülprozess selbsttätig gelöscht wird, damit die umweltpolitischen und benutzerorientierten Vorteile der automatischen Dosierung möglichst häufig genutzt werden.In the case of a fill level monitoring device for a device in which the control panel has a handle for selecting an automatic dosage of system detergents or dishwashing detergents or a manual dosing of made-up detergents or dishwashing detergents into a chamber of the washing machine or dishwasher provided for providing individual doses the invention can be advantageously further developed in that an automatically triggered signaling can be deleted by actuating the handle in the sense of manual dosing. The triggered signaling can be both optical and acoustic, but the signaling to be deleted can only be the acoustic signal. Then the operator remains visually informed of an almost empty container, but the annoying acoustic signal can be deleted for the individual case of manual dosing. The control of the supply and metering device is advantageously designed in such a way that a manual dose selection is automatically deleted after the washing or rinsing process has expired, so that the environmental and user-oriented advantages of automatic metering are used as often as possible.
Zur Vermeidung weiterer Bedienungshandlungen kann eine vorteilhafte Weiterbildung der Erfindung darin bestehen, daß alle Signale durch die Rückkehr der die Signalgabe auslösenden Sensoreinrichtung in ihren Ruhezustand löschbar sind.In order to avoid further operating actions, an advantageous development of the invention can consist in that all signals can be canceled by the return of the sensor device which triggers the signaling to its idle state.
Übrigens ist für alle Signalgaben (optisch und akustisch) von Vorteil, wenn die jeweilige Signalgabe bei Erreichen des zutreffenden Kriteriums zunächst nur vorbereitet wird, die Auslösung der Signalgabe jedoch erst bei Anforderung der automatischen Dosierung, z.B. bei der Wahl eines Wasch- oder Spülprogramms, erfolgt.Incidentally, it is an advantage for all signaling (optical and acoustic) if the respective signaling is initially only prepared when the relevant criterion is reached, but the signaling is only triggered when automatic dosing is requested, e.g. when choosing a washing or rinsing program.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels ist die Erfindung nachstehend erläutert. Es zeigen
- Fig. 1 eine schematische Darstellung der Anordnung von vier Vorratsbehältern für Wasch- oder Spülmittel-Wirkstoffe und
- Fig. 2 ein Ausführungsbeispiel für eine Bedienblende, die Handhaben und Signaleinrichtungen gemäß der Erfindung enthält.
- Fig. 1 is a schematic representation of the arrangement of four storage containers for detergents or detergents and
- Fig. 2 shows an embodiment of a control panel that contains handles and signaling devices according to the invention.
In Fig. 1 ist die schematische Anordnung der Vorratsbehälter BV für Vollwaschmittel, BF für Feinwaschmittel, BB für Bleichmittel und BW für Weichspülmittel im Vorrats- und Dosiergerät dargestellt. Die größeren Behälter haben ein Volumen, das etwa doppelt so groß ist wie das Volumen eines hier nicht näher dargestellten Transportbehälters für Wasch- oder Spülmittel-Wirkstoffe. Beispielsweise haben die großen Behälter ein Volumen von 6,6 Litern, während der kleine Vorratsbehälter BW ein Volumen von 4,3 Litern hat. Ungefähr auf halber Höhe jedes Behälters ist eine Markierung TF entsprechend einem im oberen Behälterteil unterbringbaren Entnahmevolumen gleich dem Volumen eines Transportbehälters angebracht. Im unteren Bereich jedes Behälters ist eine weitere Markierung RF angebracht, die das Niveau der Restfüllmenge RFM im Behälter anzeigt.1 shows the schematic arrangement of the storage containers BV for heavy-duty detergents, BF for mild detergents, BB for bleach and BW for fabric softener in the storage and dosing device. The larger containers have a volume that is approximately twice as large as the volume of a transport container for detergent or dishwashing detergent substances, not shown here. For example, the large containers have a volume of 6.6 liters, while the small storage container BW has a volume of 4.3 liters. Approximately halfway up the height of each container, a marking TF is applied corresponding to a removal volume that can be accommodated in the upper part of the container, equal to the volume of a transport container. In the lower area of each container there is a further marking RF which indicates the level of the remaining filling quantity RFM in the container.
In Höhe dieser Markierung RF liegt der Schaltpunkt einer Sensoreinrichtung S, mit der jeder Behälter ausgestattet ist. Beim Erreichen dieses Niveaus gibt die Sensoreinrichtung ein die Signalgabe auslösendes bzw. vorbereitendes Signal an die Steuereinrichtung (nicht dargestellt). Diese Signalgabe kann im optischen Bereich beispielsweise aus einer blinkenden Leuchtdiode und im akustischen Bereich aus einem piezokeramischen Schwinger gebildet sein. Der Behälter BW für die Bevorratung von Weichspülmittel hat ein Gesamtvolumen von beispielsweise 4,3 Liter. Ist seine Restfüllmenge erreicht (Niveau RF), dann können noch maximal fünf Waschprozessen je eine Weichspülmittel-Dosis von 60 ml zugegeben werden.The switching point of a sensor device S, with which each container is equipped, lies at the level of this marking RF. When this level is reached, the sensor device sends a signal which triggers or prepares the signal to the control device (not shown). This signaling can be formed, for example, from a flashing light-emitting diode in the optical area and from a piezoceramic oscillator in the acoustic area. The BW container for storing fabric softener has a total volume of, for example, 4.3 liters. Once its remaining filling quantity has been reached (level RF), a maximum of five washing processes, each with a softener dose of 60 ml, can be added.
Die Restfüllmengen sind so eingerichtet, daß bei der von der Sensoreinrichtung S ausgelösten Signalgabe jeweils zwei volle Transportbehälter-Volumina in die Behälter BV, BF und BB eingefüllt werden können, während der Vorratsbehälter BW oberhalb des Restfüll-Niveaus RF etwas mehr als das Volumen eines Transportbehälters faßt.The remaining filling quantities are set up so that when the signaling device S triggers, two full transport container volumes can be filled into the containers BV, BF and BB, while the storage container BW above the residual filling level RF is slightly more than the volume of a transport container sums up.
Die Restfüllmengen betragen etwa 1/25 bis etwa 1/6 der Gesamtvolumina der jeweiligen Behälter. Beispielsweise betragen die Restfüllmengen in den großen Behältern BV, BF und BB 600 ml entsprechend 1/11 der Gesamtfüllmenge jedes großen Behälters und 300 ml im kleinen Behälter BW entsprechend ca. 1/14 des Gesamtfüllvolumens.The remaining filling amounts are about 1/25 to about 1/6 of the total volumes of the respective containers. For example, the remaining filling quantities in the large containers BV, BF and BB are 600 ml corresponding to 1/11 of the total filling quantity of each large container and 300 ml in the small container BW corresponding to approx. 1/14 of the total filling volume.
In der Bedienblende gemäß Fig. 2 sind Handhaben H1 zum Ein- und Ausschalten des Vorrats- und Dosiergerätes, HH zur Eingabe der zu berücksichtigenden Wasserhärte, HD zur Wahl der Dosierung (automatische oder Handdosierung) und HW zur Wahl der Weichspülmittel-Dosierung angeordnet. Den Bedienungshandhaben HH, HD und HW sind zur Sichtbarmachung ihrer Einstellung Anzeigeelemente LED zugeordnet. Sie sind entsprechend beschriftet.In the control panel according to FIG. 2, handles H1 for switching the supply and dosing device on and off, HH for entering the water hardness to be taken into account, HD for selecting the dosage (automatic or manual dosing) and HW for selecting the softener dosage are arranged. Display elements LED are assigned to the operating handles HH, HD and HW to make their setting visible. They are labeled accordingly.
Darüber sind Signalleuchten SVR zur Anzeige der Restfüllmenge von Vollwaschmittel, SFR zur Anzeige der Restfüllmenge von Feinwaschmittel, SBR zur Anzeige der Restfüllmenge von Bleichmittel und SWR zur Anzeige der Restfüllmenge von Weichspülmittel angeordnet. Weiterhin sind noch Signalleuchten für die Anzeige einer Entnahme in der Menge des Volumens eines Transportbehälters angeordnet; sie tragen die Bezeichnungen SVTF, SBTF und SWTF. Im dargestellten Beispiel ist angedeutet, daß die Leuchten SVR, SVTF und SWTF leuchten. Dies soll bedeuten, daß im Behälter BV die Restfüllmenge RFM, also das Niveau RF, erreicht ist, während im Weichspülmittel-Vorratsbehälter BW erst die Entnahmemenge TV entsprechend dem Volumen eines Transportbehälters fehlt, also das Niveau TF erreicht ist. Bei dieser Anzeige sollte die Bedienungsperson den Behälter BV mit dem Inhalt zweier Transportbehälter für Vollwaschmittel und den Behälter BW mit dem Inhalt eines Transportbehälters für Weichspülmittel auffüllenSignal lights SVR for displaying the remaining filling quantity of heavy-duty detergent, SFR for displaying the remaining filling quantity of mild detergent, SBR for displaying the remaining filling quantity of bleach and SWR for displaying the remaining filling quantity of fabric softener are arranged above. Furthermore, signal lights for the display of a removal in the amount of the volume of a transport container are arranged; they are called SVTF, SBTF and SWTF. In the example shown it is indicated that the lights SVR, SVTF and SWTF light up. This is to mean that the residual filling quantity RFM, that is to say the level RF, has been reached in the container BV, whereas in the fabric softener storage container BW the amount of TV removed corresponding to the volume of a transport container is missing, that is to say the level TF has been reached. With this display, the operator should fill container BV with the contents of two transport containers for heavy-duty detergents and container BW with the contents of a transport container for fabric softener
Abweichend von dieser Empfehlung kann die Bedienungsperson jedoch lediglich den Inhalt eines Transportbehälters für Vollwaschmittel in den Vorratsbehälter BV einfüllen. Dann kehrt die Sensoreinrichtung S wieder in ihren Ruhezustand zurück und löscht alle vorher eingeschalteten Leuchten SVR, SVTF und SWTF.In deviation from this recommendation, however, the operator can only fill the contents of a transport container for heavy-duty detergents into the storage container BV. Then the sensor device S returns to its idle state and extinguishes all previously switched on lights SVR, SVTF and SWTF.
Entsprechend kann die Bedienungsperson den Inhalt zweier Transportbehälter von Vollwaschmittel in den Vorratsbehälter BV entleeren, dessen Sensoreinrichtung dann ebenfalls alle Signalleuchten - auch die Signalleuchte SWTF - löscht.Accordingly, the operator can empty the contents of two transport containers of heavy-duty detergent into the storage container BV, the sensor device of which then also clears all the signal lights - including the signal light SWTF.
Das Auffüllen lediglich des Vorratsbehälters BW durch den Inhalt eines Transportbehälters von Weichspülmittel führt keinerlei Veränderung in der Signalgabe herbei, weil der Behälter BV nicht gefüllt wurde und seine Sensoreinrichtung daher keine Signallöschung veranlassen konnte. Aus diesem Zustand heraus kann die Bedienungsperson noch einige Dosiervorgänge automatisch ablaufen lassen, wird sich jedoch durch die akustische Signalgabe ständig an das Nachfüllen des Behälters erinnern lassen müssen.Filling only the BW storage container with the contents of a transport container of fabric softener does not result in any change in the signaling because the container BV has not been filled and therefore its sensor device has none Cause signal cancellation. From this state, the operator can still run a few dosing processes automatically, but will have to be constantly reminded of the refilling of the container by the acoustic signal.
Die Steuereinrichtung kann auch so konzipiert sein, daß die akustische Signalgabe AS erst nach einer gewissen Zahl von Dosiervorgängen ab Erreichen der Restfüllmenge eingeschaltet wird. Dazu ist die Steuereinrichtung mit einem Zähler ausgestattet, der jeweils eine Anzahl von Dosiereinheiten summieren kann, die ganzzahlige Teile der tatsächlichen Dosiermenge sind. Nach der Zählung einer Zahl von Dosiereinheiten, die kleiner sein sollte als diejenige der gesamten Restfüllmenge RFM, wird das akustische Signal eingeschaltet. Eine vorteilhafte Alternative kann auch darin gesehen werden, daß eine bereits beim Erreichen des Reserveniveaus RF ausgelöstes akustisches Signal nach Erreichen der vorgenannten Obergrenze verstärkt wird und/oder bis zum Auffüllen des geleerten Behälters nicht mehr löschbar ist.The control device can also be designed in such a way that the acoustic signaling AS is only switched on after a certain number of dosing processes from reaching the remaining filling quantity. For this purpose, the control device is equipped with a counter, which can each add up a number of dosing units, which are integral parts of the actual dosing quantity. After counting a number of dosing units, which should be less than that of the total remaining filling quantity RFM, the acoustic signal is switched on. An advantageous alternative can also be seen in the fact that an acoustic signal already triggered when the reserve level RF is reached is amplified after the aforementioned upper limit has been reached and / or cannot be erased until the emptied container is filled.
Die Zahl der Dosiereinheiten, die der gesamten Restfüllmenge entspricht, ist ebenfalls bekannt und bildet die Obergrenze für die mögliche Dosierung aus der Restfüllmenge. Sobald diese Obergrenze erreicht ist, kann die Steuereinrichtung selbsttätig von automatischer auf Handdosierung umschalten und hierbei ggf. die akustische Signalgabe abschalten. Das akustische Signal sollte allerdings automatisch immer dann eingeschaltet sein, solange der geleerte Behälter nicht wieder gefüllt wurde und automatische Dosierung angefordert wird.The number of dosing units that corresponds to the total remaining filling quantity is also known and forms the upper limit for the possible dosing from the remaining filling quantity. As soon as this upper limit is reached, the control device can automatically switch from automatic to manual dosing and, if necessary, switch off the acoustic signal. However, the acoustic signal should always be switched on automatically as long as the emptied container has not been refilled and automatic dosing is requested.
Eine weitere Verstärkung des eingangs erwähnten "erzieherischen Effekts" kann noch dadurch erzielt werden, daß beim Erreichen der vorstehend genannten Obergrenze überhaupt kein Wasch- oder Spülprozeß mehr gestartet werden kann.A further reinforcement of the "educational effect" mentioned at the outset can be achieved in that no washing or rinsing process can be started at all when the above-mentioned upper limit is reached.
