Abstract

The present invention provides a roaster heater of a gas roasting stove, which mainly comprises a body, a roaster door and a roaster burner, wherein the body is communicated with an inner holding space storing food, and one side of the body can be opened and closed; the roaster door is used for opening and closing the inner holding space of the body; the roaster burner generates igniting flames heating the inner holding space of the body. A heat discharge part connected with the roaster burner is arranged on the side wall of the inner holding space of the body to guide the igniting flames and combustion heat which re generated in the roaster burner to discharge infrared rays to the inner holding space of the body and heat the loaded food. The present invention has the effect that the roaster heater causes the heat discharge part discharging the infrared rays to directly heat and cook the food, which reduces heat loss; a reflecting plate is arranged on the heat discharge part to intensively discharge the infrared rays to the inner holding space and prevent discharging the infrared rays to the side surface of the body to overheat the body, which enhances the utilization rate of energy. The back surface of the heat discharge part is inserted into the body for assembly, which is easy to clear foreign substances.

The oven heat device of fuel gas oven

Technical field

The present invention is the oven heat device of relevant fuel gas oven, particularly utilizes the oven heat device of the fuel gas oven of infrared ray heated food.

Background technology

Fuel gas oven is to comprise baking box portion, grill portion, last burner portion, have the advantage that various cookings can be made individually or simultaneously, thereby the use amount of family or place of business increases gradually.

As shown in Figure 1, downside being provided with of fuel gas oven utilizes vertical flame and heat to mainly carrying out the baking box 1 of barbecue, upside being provided with of its baking box 1 utilizes thermal convection current mainly to bake the grill 2 of fresh fish, the top of its grill 2 is provided with in order to heat the container of splendid attire food, exposes the superincumbent burner portion 4 of going up and possess a plurality of burners.Has installed in order to discharge baking box portion 1 back of this equipment, the back protective device portion 5 that the exhaust that takes place in the grill portion 2 is discharged to the outside, and the back of above-mentioned baking box 1 is provided with barbecue motor (not shown) and convection motor (not shown).

As shown in Figure 2, baking box portion 1 possesses the body 6 of the side switching that is communicated with the inner accepting space 6a that stores food, opens and closes the oven door 7 of the inner accepting space 6a of body 6, and baking box burner 8 formations of the combustion heat take place in the inside that is formed on body 6.

This fuel gas oven person of being to use carries out cooking in baking box 1 when barbecue or bread etc. are cooked, utilize grill portion 2 to arrange when baking soft roasting such as fresh meat, it is that the burner 3 of the last burner portion 4 that utilizes that top exposes is arranged that food is contained in the general cooking of heating in the container.

Be enabled in the baking box burner that forms on the inner accepting space 6a of body 6 when cooking and the combustion heat takes place in baking box portion 1, the combustion heat causes that the heat of generation is communicated to inner accepting space 6a by convection current, utilizes the advection heat cooked food of conduction.

But in this fuel gas oven, so heated unnecessary space, there is the problem that has strengthened heat loss because utilize first-class cooked food in baking box portion 1.

Summary of the invention

For solving the above problems, the food use infrared ray that the purpose of this invention is to provide the needs cooking directly heats, and can reduce the oven heat device of the fuel gas oven of heat loss.

For achieving the above object, the technical solution used in the present invention provides a kind of oven heat device of fuel gas oven, its structure mainly includes and is communicated with the inner accepting space of storage food and a side opens and closes the body of face, open and close the oven door of the inner accepting space of above-mentioned body, the baking box burner of the ignition flame of the inner accepting space of generation heater body, on the sidewall of the inner accepting space of body, a plurality of heat units that are connected with the baking box burner are installed, per two heat units directly connect by tube connector, with the ignition flame and the combustion heat that generates in the guiding baking box burner, emit the food of infrared ray and heating loading to the inner accepting space of body.

Described heat unit is bumped on body near a side of body.

The structure of described heat unit is to be made of the ignition flame that generates in the conduction baking box burner and metallic fiber pipe that reaches the combustion heat and the glass-ceramic pipe that wraps on the metallic fiber pipe outer tube wall.

Ceramic glaze pipe in the described heat unit is enclosed with on the inner accepting space one side semicircle pipe radially of body and outwards emits ultrared reflecting plate.

Effect of the present invention is that the oven heat device makes and emitted ultrared heat unit directly heating and cooked food, reduces the loss of heat; Reflecting plate is set on the heat unit makes to concentrate and emit infrared ray, prevent that emitting infrared ray to the body side makes body overheated, improve energy utilization ratio to inner accepting space.The reverse side of heat unit is bumped into the enterprising luggage of body joins, and removes the operation of foreign matter easily.

The specific embodiment

The present invention is described in detail to reach embodiment in conjunction with the accompanying drawings.

The oven heat device of fuel gas oven of the present invention is to include to be communicated with the inner accepting space of storage food and a side opens and closes the body 6 of face, open and close the oven door of the inner accepting space of above-mentioned body 6, the baking box burner of the ignition flame of the inner accepting space of generation heater body 6, on the sidewall of the inner accepting space 6a of body 6, a plurality of heat units 103 that are connected with baking box burner 102 are installed, per two heat units 103 directly connect by tube connector 108, with the ignition flame and the combustion heat that generates in the guiding baking box burner, emit the food of infrared ray and heating loading to inner accepting space 6 a of body 6.
