The utility model is characterized in that the space between the heating disk and the outer cooker is provided with an elastic supporting plate, wherein the heating disk is supported on the elastic supporting plate; the space between the heating disk and the elastic supporting plate is provided with supporting rods, and the heating disk is supported on the elastic supporting plate by the supporting rods which are annularly distributed between the heating disk and the elastic supporting plate which is a steel plate in a shape of a flat plate; the bottom of the heating disk is provided with a bunting and pushing rod which is bunted and pressed on the power switch; the bottom of the heating disk is provided with the bunting and pushing rod; the space between the bunting and pushing rod and the power switch is provided with a connecting rod, and the bunting and pushing rod controls the power switch to be switched on and off by the connecting rod. The utility model has the advantages of simple structure, low cost and double security.
Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan, is a kind of electric pressure cooking saucepan by pot inner pressure automatic control power supply switch on and off specifically.
Background technology
At present, people have proposed very high requirement to the security of electric pressure cooking saucepan when working voltage power pot, when particularly the pressure in the electric pressure cooking saucepan pot increases to a certain degree, how to realize that automatic shutoff of power switch plays very crucial stage.For this reason, people have designed multiple structure and have gone to realize closing automatically of power switch, as Chinese patent " a kind of adjustable pressure electric pressure cooking saucepan " (ZL98234948.3), the described technical scheme of this patent mainly is provided with spring between the interior pot of electric pressure cooking saucepan and shell, pot is connected with elasticity between shell in realizing.When the pressure in the pot increased to a certain degree, interior pot moved down and passes through push rod roof pressure power switch, thereby closes the electric pressure cooking saucepan power supply, avoided the pressure in the pot to continue to rise, and played safety protection function.For reaching same purpose, people are provided with the combination butterfly spring between the interior pot of electric pressure cooking saucepan and shell, and pot is connected with elasticity between shell in realizing by the combination butterfly spring.Existing patent documentation shows, people only are provided with elastic supporter between the interior pot of electric pressure cooking saucepan and shell guarantee in safe range the pressure in the pot, when if power switch breaks down, pressure in the electric pressure cooking saucepan will continue to rise, thereby can't satisfy safety requirements, in other words only by one heavily insurance also do not reach instructions for use, in addition, adopt common spring or combination butterfly spring to have complex structure, inconvenient shortcoming is installed.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is low, have the electric pressure cooking saucepan of double insurance.
The utility model is achieved through the following technical solutions.
A kind of electric pressure cooking saucepan, comprise pot cover, shell, outer pot, interior pot and power switch, be provided with elastic seal ring between pot cover and interior pot, heat-generating disc is close in the interior pot the bottom of a pan, it is characterized in that: be provided with elastic supporting plate between described heat-generating disc and outer pot, heat-generating disc is supported on the elastic supporting plate.
Be provided with support bar between described heat-generating disc and elastic supporting plate, heat-generating disc by they sup-port on elastic supporting plate.
Described support bar annular distribution is between heat-generating disc and elastic supporting plate.
Described elastic supporting plate is the tabular steel plate.
The bottom of described heat-generating disc is provided with propulsion arm, and the propulsion arm roof pressure is on power switch.
The bottom of described heat-generating disc is provided with propulsion arm, is provided with connecting rod between propulsion arm and power switch, and propulsion arm is by the switching of connecting rod control power switch.
The utility model compared with prior art has the following advantages.
The utility model mainly is provided with a spring steel plate between heat-generating disc and outer pot, heat-generating disc is supported on the spring steel plate, in addition, is provided with propulsion arm in the bottom of heat-generating disc, and the propulsion arm roof pressure is on power switch.When the pressure in the pot increased to required maximum pressure, heat-generating disc was by propulsion arm roof pressure power switch, thus shutoff voltage power pot power supply.When if power switch breaks down, the pressure in the pot continues to rise, and interior pot moves down with heat-generating disc under pressure, when moving down into certain distance, in pot be separated with elastic seal ring on the pot cover, the steam in the pot is revealed outward from elastic seal ring, thereby reduces the interior pressure of pot.The mode that the technical program matches with frame for movement by Electronic Control realizes the electric pressure cooking saucepan double insurance, simple in structure and easy realization.Spring steel plate is fixed on outer pot bottom place, and heat-generating disc on spring steel plate, is installed very conveniently by they sup-port, and in addition, it is not very high that parts are required, and can reduce the manufacturing cost of product.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model electric pressure cooking saucepan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model electric pressure cooking saucepan is described in further detail.
As shown in Figure 1, electric pressure cooking saucepan described in the utility model mainly is made up of with power switch pot cover, shell, outer pot, interior pot, be provided with elastic seal ring between pot cover and interior pot, heat-generating disc 2 is close in interior pot 1 the bottom of a pan, be provided with elastic plate shape steel plate 3 between heat-generating disc 2 and outer pot, heat-generating disc 2 and 3 of property tabular steel plates are provided with support bar 4, and heat-generating disc 2 is supported on the elastic plate shape steel plate 3 by support bar 4.In the present embodiment, support bar is three, and support bar is distributed between heat-generating disc and elastic supporting plate apart from ring-type with same intervals.The bottom of heat-generating disc is provided with propulsion arm 5, and propulsion arm 5 direct roof pressures link to each other with power switch on power switch or by connecting rod.When propulsion arm moves down, an end of propulsion arm pushing tow connecting rod, the other end roof pressure power switch of connecting rod, thus close the power supply of electric pressure cooking saucepan.
