At this moment, at the set inside having heaters 150 of said first air intake passage 130, said heater 150 is used for the extraneous air heating with the low temperature that sucks, and reaches the high temperature of the baking needed of washings.And, though not shown, also append and be provided with water content detection sensor, said water content detection sensor is used to detect the moisture of the said cylinder 120 inner washings of throwing in.Can use form arbitrarily as said water content detection sensor,, can use, detect the electrode sensor of moisture through changes in resistance based on moisture through pair of electrodes as an example.
Wherein, said first air intake passage 130 and second air intake passage 140 are physically separated two structures, but the present invention is defined in this, also can consider the example that both are integrally formed.
At this moment, in said first air intake passage 130, suck air outside through the air entry (not shown) that is formed at said body 102.The extraneous air that sucks thus will be heated to high temperature by said heater 150, flow into the inside of said cylinder 120 and dry washings, then, flow into the front passage 160 of the front downside that is positioned at said cylinder 120.
In addition, in the air that flow into said front passage 160, include foreign substances such as fine hair that the surface of said washings exists or dust.Therefore, the set inside of passage 160 is useful on the lint filter 162 that filters said foreign substances in said front, thereby filters out foreign substances when making leaked-in air via said lint filter 162.
In said front passage 160, be connected with first exhaust passage 180.Said first exhaust passage 180 is formed with the part of exhaust flow path that is used for the hot blast through said front passage 160 is discharged to the outside of body 102; Portion is provided with blowing fan 170 within it; Said blowing fan 170 is used to suck the air in the said cylinder 120 and blows to the external forced of dryer, so that produce flowing of air through said air-breathing stream and exhaust flow path.

Below, will the process of drying among the aforesaid embodiment be described with reference to Fig. 4.Fig. 4 is for carrying out the flow chart of drying course among the embodiment that illustrates among Fig. 1.When beginning to dry, carry out that said cylinder is rotated and with the main baking step of warm-air supply to the inside of cylinder.At this moment, the air that flow into the inside of said cylinder through said heater 150 heating by said blowing fan 170 forms hot blast.
After carrying out this warm-air supply process, stop the operation of said heater with the stipulated time.Wherein, supplying with the duration of hot blast process and can set arbitrarily, as an example, is that the execution that said warm-air supply can continue is about 45 ~ 55 minutes under 60 minutes the situation at predefined drying time.That is, make warm-air supply keep the over half at least of whole drying course, thereby can prevent that drying time is long carry out.
According to circumstances, the content of the moisture that the said warm-air supply time is comprised by washings, i.e. moisture content decision.That is, if the moisture content of the state that final oven dry is accomplished is 5%, said warm-air supply continues to proceed to moisture content and reaches about 7%, in its later drying course, in the state execution down out of service of said heater.
At this moment, when the internal temperature of cylinder reaches 40 ℃, said blowing fan continuous service cooling step, according to circumstances, in the reasonable time of making the state maintenance below 40 ℃.Thus, the final step carrying out the washings oven dry below 40 ℃ is dried the fold that generates in the main baking step and is untied under the environment of low temperature.
Fig. 5 is the chart according to variations in temperature fold generation degree in the said cooling step.With reference to Fig. 5; Continue about about 5 minutes situation with cooling step, the temperature when promptly oven dry finishes is 45 ℃ a situation relatively the time, and cooling step is being continued about about 15 minutes; So that the temperature of oven dry when finishing is under 30 ℃ the situation, can suppress the generation of fold.As a reference, the numerical value of the longitudinal axis is high more among Fig. 5, then is equivalent to fold and generates still less.
Can know that as stated chilling roll temperature inside more rapidly in cooling step can suppress the generation of fold.Therefore, after entering into cooling step, detect the internal temperature of cylinder, and exceeding under 40 ℃ the situation, example as shown in Figure 6 can consider to increase the rotary speed of said blowing fan, to cool off more rapidly.In the case, the drying rate in the cooling step also will speed, and have the effect that can shorten whole drying time simultaneously.
Also can consider this cooling step is applicable to the example of main baking step.Fig. 7 is described as time passes drum variation of temperature chart in the main baking step among the embodiment that illustrates among Fig. 1.
As shown in Figure 7; At the main baking step initial stage; The temperature of drum is increased in low relatively scope; In the mid-term that heat that has at hot blast and the heat of evaporation that is caused by water evaporates are kept in balance, the internal temperature of cylinder will reach roughly about 200 ℃ and keep certain.
Subsequently, along with the moisture content reduction of washings, it is big that the heat that hot blast has becomes relatively, and thus, the internal temperature of cylinder will increase gradually.As stated, when the temperature of drum increased, though can shorten drying time, fold obtained solidifying, even oven dry finishes also will generate a large amount of folds.Therefore, when the temperature that detects drum increased gradually, the operation that stops said heater that also can be intermittently was to suppress the increase of drum temperature.In addition, under the situation that the internal temperature of cylinder increases, also can consider to increase as stated the rotary speed of blowing fan, temperature rises and the example of the generation of fold to suppress.
The present invention is defined in aforesaid embodiment, and in the category that does not exceed basic fundamental thought of the present invention, the operator of relevant industries can carry out various deformation to it, and the said distortion of carrying out should belong to claim scope of the present invention.
