Abstract
The utility model discloses an air convection type thermal insulating device. The air convection type thermal insulating device comprises a shell, and is characterized in that a thermal insulating disc body is arranged in the shell and internally provided with an air thermal insulating area, wherein the upper end of the thermal insulating disc body is closed, an air inlet is formed in the lower end of the thermal insulating disc body, and an air outlet is formed in the side wall of the thermal insulating disc body; a heating device is arranged at the upper part of the inner side of the thermal insulating disc body; and an air inlet device is arranged on the air inlet. As an improvement, the air inlet device comprises a fan fixedly arranged on the air inlet. A temperature controller is arranged at the bottom of the thermal insulating disc body and is electrically connected with a heating tray. According to the air convection type thermal insulating device, the air thermal insulating area is additionally arranged between a radiant cooker heating tray and the shell, the relatively stable air thermal insulating screen is formed by utilizing air flow generated from the fan, the low temperature rise of the product shell can be ensured; and in addition, the temperature controller is additionally arranged outside the thermal insulating disc body inside a radiant cooker, so that secondary protection is achieved when a circuit board breaks down.
Description
Technical field
The utility model belongs to electric pottery stove and uses the heat-proof device field, specifically, relates to a kind of cross-ventilation formula heat-proof device.
Background technology
At present, the kitchen appliance stove and accessory great majority that generally use of people are based on electromagnetic oven and traditional light-wave cooker; Electromagnetic oven can not use little fire to heat continuously, and can produce the electromagnetic wave of harmful human body, and human body and health are had injury.And the heat of traditional light-wave cooker can not be heated very soon, can not carry out quick-fried, and waste energy very much, so people have invented electric pottery stove.Though electricity pottery stove has solved above-mentioned shortcoming, electric pottery stove also exists the disadvantageous problem of heat radiation, and does not have the thermal insulation layer protection between electric pottery stove heat-generating disc and the shell, and heat distributes and directly causes the product casing temperature rise too high.The temperature control of electricity pottery stove only relies on attemperating unit single on the boiler face, and when wiring board broke down, temperature was uncontrollable.Wiring board and heat-generating disc are installed in the same space the inside, and the air-flow that blower fan produces is made the temperature rise of wiring board too high by the heat-generating disc heating.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defective, and a kind of simple in structure, relatively low cross-ventilation formula heat-proof device of assurance electric pottery stove outer covering temperature rise is provided.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of cross-ventilation formula heat-proof device comprises shell, it is characterized in that: be provided with heat insulation disk body in the described shell, be provided with the air thermal insulation areas in the heat insulation disk body; The upper end closed of described heat insulation disk body, the lower end is provided with air inlet, and the sidewall of heat insulation disk body is provided with air outlet simultaneously; Described heat insulation disk body inside upper part is provided with heater; Described air inlet is provided with air-intake device.
As a kind of improvement, described air-intake device comprises the blower fan that is fixedly mounted on the air inlet.
As a kind of improvement, described heater is a heat-generating disc, and heat-generating disc is electrically connected with wiring board, and wiring board is arranged on the bottom face of heat insulation disk body.
As a kind of improvement, the bottom of described heat insulation disk body is equipped with temperature controller, and temperature controller is electrically connected heat-generating disc.
As a kind of improvement, the number of described air inlet is one, and the number of air outlet is two.
Owing to adopted technique scheme; compared with prior art; the utility model increases an air thermal insulation areas between electricity pottery stove heat-generating disc and shell; utilize blower fan to produce air stream, form metastable air heat shield, guarantee that the product casing temperature rise is relatively low; simultaneously; at attemperating unit of the external increase of electricity pottery furnace interior thermal insulating disc, when avoiding wiring board to break down, can obtain second protection.In addition, wiring board places the space that is different from heat-generating disc, and the natural wind cooling that utilizes blower fan to produce reaches the effect of energy-conservation of consumption reduction.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure: the 1-shell; The 2-heat-generating disc; The heat insulation disk body of 3-; 4-air thermal insulation areas; The 5-air inlet; The 6-blower fan; The 7-wiring board; The 8-temperature controller; The 9-air outlet.
The specific embodiment
Embodiment 1:
As shown in Figure 1, a kind of cross-ventilation formula heat-proof device comprises shell 1, is provided with heat insulation disk body 3 in the described shell 1, is provided with air thermal insulation areas 4 in the heat insulation disk body 3.The upper end closed of described heat insulation disk body 3, lower end are provided with air inlet 5, and the sidewall of heat insulation disk body is provided with air outlet 9 simultaneously.Heat insulation disk body 3 inside upper part are provided with heater, and air inlet 5 is provided with air-intake device simultaneously.
In the present embodiment, described air-intake device comprises the blower fan 6 that is fixedly mounted on the air inlet 5.Heater is a heat-generating disc 2, and heat-generating disc 2 is electrically connected with wiring board 7, and wiring board 7 is arranged on the bottom face of heat insulation disk body 3.
In the present embodiment, the bottom of described heat insulation disk body 3 is equipped with temperature controller 8, and temperature controller 8 is electrically connected heat-generating disc 2.
The utility model gives a kind of embodiment of the best, and the number of air inlet is one, and the number of air outlet is two.
During work, blower fan is from air inlet rotation generation air stream, and part cooling places the wiring board of insulated space outside, and most of at convection type insulated space formation air thermal insulation areas, heated air is derived from air outlet.If thermal insulating disc body temperature degree rises to the uniform temperature value, then make the temperature controller action that places heat insulation disk body bottom, cut off the work of heat-generating disc.When thermal insulating disc body temperature degree reached the uniform temperature value, temperature controller recovered the work of heat-generating disc again, thereby effectively controlled the temperature rise of product.
The utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
