Abstract
The utility model relates to a pressure protection device of an electric pressure cooker; the device comprises a heat insulation cover which is arranged in the electric pressure cooker; a heating plate is elastically arranged at the inner bottom of the heat insulation cover; the heating plate can extend out of the heat insulation cover and is connected with a button support; at least one button switch is arranged on the button support; and an adjusting support which can be contacted with a contact pin is arranged at a position at the outer bottom of the heat insulation cover or the base of the electric pressure cooker which corresponds to the button switch. The button switch is fixedly arranged on the button support through a buckle or a screw. The adjusting support is provided with a driving mechanism which is contacted with the contact pin. The driving mechanism comprises an adjusting nut which is fixedly arranged on the adjusting support corresponding to the position of the contact pin, and an adjusting screw which is in threaded connection onto the adjusting nut. According to the pressure protection device of the electric pressure cooker, the pressure control or an over-pressure safe protection function when the electric pressure cooker is used for cooking can be realized. The pressure protection device of the electric pressure cooker has the characteristics of simple design, reasonable structure, low manufacturing cost, convenience in assembly, safe and reliable use.
Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan, specifically is a kind of pressure protective device of electric pressure cooking saucepan.
Background technology
At present, generally has pressure controlled switch in the electric pressure cooking saucepan that people use.A kind of electric pressure cooking appliance was disclosed on June 27th, 2007 like Chinese patent document number CN2914931; Comprise a pot body, outer pot, interior pot, pot cover, heat-generating disc, but pot cover and outer pot or pot body rigidity are fastened on one, are provided with sealing ring between pot cover and interior pot; Interior pot places on the heat-generating disc; Heat-generating disc is installed on the elastomer of outer pot bottom, is equiped with gauge tap on heat-generating disc or the elastomer, and corresponding gauge tap position is provided with catch bar on the outer pot; Wherein be equiped with touch part on heat-generating disc or elastomer or the gauge tap, be equiped with the cut-off switch that when gauge tap lost efficacy, can contact on outer pot or the catch bar with touch part.The pressure control value of this structure control switch and cut-off switch can not be regulated, and structure is comparatively complicated, and volume is bigger, wastes more space, assembles also comparatively loaded down with trivial detailsly, and fault rate is higher.Therefore, need further to improve.
The utility model content
The purpose of the utility model aims to provide the pressure protective device of a kind of simplicity of design, rational in infrastructure, easy, the safe and reliable electric pressure cooking saucepan of assembling, to overcome weak point of the prior art.
Press the pressure protective device of a kind of electric pressure cooking saucepan of this purpose design; Comprise the stay-warm case that is arranged in the electric pressure cooking saucepan; The inner bottom part elasticity of stay-warm case is equipped with heat-generating disc; Its architectural feature is that heat-generating disc can stretch out stay-warm case and be connected with a button support, and the button support is provided with at least one press button, the position of the base corresponding button switch of stay-warm case outer bottom or electric pressure cooking saucepan be provided with can with the adjusting support of its haptic element touching.
Said press button is fixed on the button support through buckle or screw.
Said adjusting support is provided with driving mechanism and haptic element touching.
The fixed-site that said driving mechanism comprises corresponding haptic element is being regulated the adjusting nut on the support and above that the set screw of being threaded.
The pressure control value of said press button is below 150 kPa, perhaps is 140 kPa～180 kPa.
The normal-closed end of said press button is connected with the control circuit of electric pressure cooking saucepan.
The utility model is connected with the button support that press button is installed on heat-generating disc; The corresponding adjusting support that is provided with of the base of stay-warm case outer bottom or electric pressure cooking saucepan; Press button is by regulating the adjustable drive mechanism that is provided with on the support, and the pressure when it can realize electric pressure cooking saucepan cook is controlled or the superpressure safety protection function.It has simplicity of design, rational in infrastructure, cost of manufacture is low, assembling is easy, safe and reliable characteristics.
Description of drawings
Fig. 1 is the assembly structure sketch map of the utility model one embodiment.
Fig. 2 is the stereogram (part) of Fig. 1.
Fig. 3 is the structural representation of an embodiment press button.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 3; The pressure protective device of this electric pressure cooking saucepan; Comprise the stay-warm case 7 that is arranged in the electric pressure cooking saucepan, the inner bottom part elasticity of stay-warm case 7 is equipped with heat-generating disc 6, and its heat-generating disc 6 can stretch out stay-warm case 7 and be connected with a button support 5; Button support 5 is provided with a press button 4, the position of the base corresponding button switch 4 of stay-warm case 7 outer bottoms or electric pressure cooking saucepan be provided with can with the adjusting support 1 of its haptic element 4.2 touchings.
Transfer set screw 2, its length of stretching out is changed, can change the pressure control value of press button 4, pressure control or superpressure safety protection function when making it satisfy the electric pressure cooking saucepan culinary art also can adopt two press buttones 4, satisfy two above-mentioned functions respectively.Generally speaking; Pressure controlled function when satisfying the electric pressure cooking saucepan culinary art; The pressure control value of press button 4 is below 150 kPa, preferred 120 kPa, 130 kPa, 140 kPa, the superpressure safety protection function in the time of satisfying the electric pressure cooking saucepan culinary art; The pressure control value of press button 4 is 140 kPa～180 kPa, preferred 150 kPa, 160 kPa, 170 kPa.
