Abstract

The utility model discloses an electric pressure cooker provided with the function of overpressure protection; the middle of the bottom of an inner layer is opened with a middle hole and provided with a cantilever support piece which is integrated with the cooker into a whole; a heat emitting plate is arranged on the cantilever support piece; convex slots are punched at the bottom of the inner layer and configured in pairs; spring pieces are arranged on the convex slots to form a bridge shaped structure. When overpressure occurs in the electric pressure pot, a gap can be formed between a cover body and an internal bladder to cause the electric pressure pot to release pressure, thus avoiding pot explosion and achieving the goal of safe use. The structure is simple and the cost is reduced.

Description

Electric pressure cooking saucepan with overpressure protection

Technical field

The utility model relates to cooking utensil, relates in particular to the electric pressure cooking saucepan that a kind of family expenses have overpressure protection, to increase the security of using.

Background technology

Electric pressure cooking saucepan is the upgraded product of conventional high-tension pot and electric cooker, it combines the characteristics and the strong point of pressure cooker and electric cooker, has solved the hazards that the conventional high-tension pot exists, and has fast cooking, multi-purpose pot, electricity saving and energy saving, safe and practical characteristics.Safe in utilization in order to ensure electric pressure cooking saucepan must be controlled the electric pressure cooking saucepan internal pressure, otherwise, when the electric pressure cooking saucepan internal pressure surpasses certain dangerous values, can produce the phenomenon of fryer, security incident takes place.Existing electric pressure cooking saucepan comprises: shell, internal layer, inner bag, lid and machine components and electric elements such as heat-generating disc and temperature detect switch (TDS).Safe in utilization in order to ensure electric pressure cooking saucepan must be controlled the internal pressure of electric pressure cooking saucepan, makes the pressure in the electric pressure cooking saucepan surpass certain dangerous values.Present electric pressure cooking saucepan internal layer is whole structure, in case steam valve, temperature switch, pressure switch, temperature controller, fuse are malfunctioning, because spring leaf is directly to be fixed on the internal layer by fixed screw, and has two fulcrums directly to contact with inner layer wall, fulcrum directly contacts with internal layer, for point, face engage, when for a long time under the superpressure state, can make the internal layer distortion, cause the temperature detect switch (TDS) cisco unity malfunction, in addition, on spring leaf, install and fix screw, fulcrum makes cost up.

The utility model content

In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of electric pressure cooking saucepan with overpressure protection, and is safe and reliable, reduces cost.

The technical scheme that its technical problem that solves the utility model adopts is: the electric pressure cooking saucepan that the utlity model has overpressure protection; have mesopore in centre position, internal layer bottom; and be provided with the cantilever support sheet, heat-generating disc is installed on the cantilever support sheet, and dashing in the internal layer bottom has tongue.

Described cantilever support sheet and internal layer are structure as a whole, and are arranged on the circular periphery of mesopore.

Described cantilever support sheet is a plurality of, is arranged on the circular periphery of mesopore equably and stretches out to internal layer bottom centre direction.

Described tongue and internal layer are structure as a whole, and are arranged on the periphery of internal layer bottom.

Described tongue is a plurality of, in pairs configuration.

Spring leaf be set at every pair of tongue above, form bridge-like structure.

The beneficial effects of the utility model are, because electric pressure cooking saucepan of the present utility model dashes in the internal layer bottom mesopore are arranged, and leave into a single integrated structure with it a plurality of cantilever support sheets, and heat-generating disc places on the cantilever support sheet.And many to tongue at the periphery of internal layer bottom towards having, make internal layer and spring leaf form bridge-like structure.Thus, when in the electric pressure cooking saucepan during superpressure, displacement by cantilever support sheet and spring leaf generation, make heat-generating disc to bottom offset, drive inner bag to bottom offset, lid is to top offset simultaneously, like this generation gap and cause release in the electric pressure cooking saucepan between lid and the inner bag, take place thereby avoid complaining and quarrel loudly, reach the purpose of safe handling.Simple in structure, reduce cost.

Description of drawings

Fig. 1 is the vertical cross-sectional schematic of overall structure that the utlity model has the electric pressure cooking saucepan of overpressure protection.

Fig. 2 is the overall structure of electric pressure cooking saucepan shown in Figure 1, takes down the schematic top plan view behind lid, the inner bag.

Fig. 3 is the cross-sectional schematic of electric pressure cooking saucepan shown in Figure 2 along the A-A line.

The specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in Figure 1, the utlity model has the electric pressure cooking saucepan of overpressure protection, at shell 1 inside suit internal layer 2 successively and inner bag 3, lid and steam valve 8 are equipped with in its top, and bottom 17 is equipped with in the bottom.Lid is made up of pot cover 5 and aluminium loam cake 6, and the periphery of aluminium loam cake 6 is bonded with sealing ring 7, during use, utilizes sealing ring 7 to be stuck between pot cover 5 and inner bag 3 upper edges, makes inner bag 3 be in sealing state.Heat-generating disc 4 is arranged in internal layer 2 and is supported on its bottom.

Fig. 2 is the schematic top plan view that takes down this electric pressure cooking saucepan behind lid, the inner bag, and Fig. 3 is the cutaway view of electric pressure cooking saucepan shown in Figure 2 along the A-A line, and internal layer 2 bottom shapes and each configuration of components are shown.Dashing in centre position, internal layer 2 bottom has mesopore 16, and leaves a plurality of cantilever support sheets 11 at the periphery of mesopore 16, and present embodiment is selected 3, and internal layer 2 and cantilever support sheet 11 are structure as a whole., dispose in pairs towards tongue 10 is arranged in internal layer 2 bottoms, can increase the rigidity at ring-type position, internal layer 2 bottom.Spring leaf 9 be set at every pair of tongue 10 above, form bridge-like structure, spring leaf 9 is contacted with internal layer 2 formation faces, can not produce metaboly.Heat-generating disc 4 is installed on the cantilever support sheet 11, in internal layer 2 bottoms pressure switch 13, temperature detect switch (TDS) 12, temperature controller 14, temperature limiter 18 is housed also, and fuse 15 is installed in below internal layer 2 bottoms and between the bottom 17.

When in the electric pressure cooking saucepan during superpressure, displacement by cantilever support sheet and spring leaf generation, make heat-generating disc to bottom offset, drive inner bag to bottom offset, lid is to top offset simultaneously, produce the gap between lid and the inner bag like this and cause release in the electric pressure cooking saucepan, take place, reach the purpose of safe handling thereby avoid complaining and quarrel loudly.
