Background technology

The existing common part of full automatic electric pressure cooker; be that pot in utilizing, pot cover, sealing ring and outer pot are combined into closed chamber; between heat-generating disc and outer pot, be provided with resilient supporting unit; after the annular seal space internal pressure raises; by interior pot bottom, heat-generating disc pressure is transmitted to the heat-generating disc support foot and drives the resilient supporting unit that is contained in outer pot bottom; make this resilient supporting unit produce distortion; utilize this deflection to drive the dynamic seal (packing) state of power-off protection apparatus and change closed chamber; when deflection was enough big, dynamic seal (packing) was lost efficacy and was produced the mode of operation of peripheral pressure release.

Structure one class of the current resilient supporting unit that generally adopts is that a plurality of cylinder-shaped compression springs or elastomers such as some block-shaped different shell fragments, disk spring constitute by combination separately, arrangement mode, this class formation is because every employed flexible member quantity of pot is on the high side, the workload that must cause making flexible member increases, and each element punching out, bend, process such as heat treatment, surface treatment all can cause individual difference in quality, numerous and diverse assembly technologies etc. must have negative effect to the quality of product, cost, efficient etc.; Another kind of technology be directly with outer pot bottom as resilient supporting unit, the heat-generating disc support foot directly places on the outer pot bottom surface, this class formation adopts brings difficulty can for the material selection and the processing of outer pot as resilient supporting unit outer pot bottom, because if outer pot bottom has satisfied the elasticity requirement, then can influence its requirement of strength as supporter; Otherwise,, then can influence its elasticity requirement as resilient supporting unit if outer pot bottom has satisfied requirement of strength.For this reason, people have designed a kind of shell fragment and outer pot of including, and shell fragment is the circle of full wafer, which is provided with some erection openings, and the bottom surface of outer pot is provided with the annular boss that raises up, and this annular boss contacts support with the shell fragment lower surface and shell fragment.This resilient supporting unit is because shell fragment is an absolute construction with respect to outer pot, and the material that does not therefore influence outer pot is selected and processing, only needs processing shell fragment separately, therefore processes simple installation, and coefficient of elasticity and amount of elastic deformation are controlled easily, the elastic deformation good linearity.But this technical scheme is because shell fragment is the circle of full wafer, and the actual support district is the outer regions of shell fragment, and mid portion there is no supporting role, i.e. waste material also increases the overall weight of product; Simultaneously, adopt the single annular boss to support circular shell fragment, the support strength of shell fragment is lower, can influence its requirement of strength as supporter.

The utility model content

The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of and can realize that big travel compression can guarantee the resilient supporting unit of enough supporting forces, elastic deformation good linearity, control accuracy height, handling ease, province's material, lightweight full automatic electric pressure cooker again.

The purpose of this utility model can realize by following technical scheme.

The utility model includes shell fragment and outer pot, it is characterized in that shell fragment is the full wafer annular, which is provided with some erection openings, the bottom surface of outer pot is provided with two annular concentric boss that raise up, and two annular concentric boss contact common support with annular shell fragment lower surface and shell fragment.

Outer shroud boss in above-mentioned two annular concentric boss is arranged on the edge in the outer pot the bottom of a pan, links to each other with the intermediate location of sidewall with the outer pot the bottom of a pan.

Circular shell fragment in the technique scheme is a tabular, or the dish shape, or corrugated.

Any one can be the annular of complete closure for two annular boss that raise up on the face of the bottom of a pan, technique scheme China and foreign countries, also the discontinuous annular that can be made up of several sections segmental arcs.

For guaranteeing elastically-deformable in the course of the work stroke of shell fragment of the present utility model and linearity, the height of annular boss is 1～6 millimeter on the above-mentioned outer pot bottom surface.

When the utility model uses, the pressure control drive rod is set under the heat-generating disc, drive rod passes the outer the bottom of a pan, the flashing switch in the corresponding pressure pot electrically-controlled component of pressure control drive rod below.During electric pressure cooking saucepan work, interior pot, sealing ring, after pot cover and outer pot fasten, the closed chamber of having formed dynamic seal (packing), the heat-generating disc heating, the closed chamber internal pressure raises, the heat-generating disc pressure-bearing, shell fragment produces downward strain under the effect that the heat-generating disc supporting-point is exerted pressure, the pressure control drive rod is thereupon to bottom offset, and when the pressure in the pressure cooker reached the operating pressure of setting, pressure control drive rod displacement was enough to drive the flashing switch and disconnects heater circuit, during superpressure, produce bigger amount of movement and lost efficacy by dynamic seal (packing) and the generation pressure release, keep repeatable, guarantee that the control accuracy of product and pressure release parameter are normal.

The beneficial effects of the utility model are: because the utility model adopts with one heart two annulus convexes to support the resiliency supported of annular shell fragment as electric pressure cooking saucepan, therefore can realize that big travel compression can guarantee enough supporting forces, elastic deformation good linearity, control accuracy height, handling ease again, the structure that is compared to existing circular shell fragment simultaneously has province's material, lightweight characteristics.
