Problems solved by technology

This structure does not drop the pressure sharply after reaching the peak value, but the pressure drop rate is still high, and it cannot be stabilized in the peak area at regular intervals, and the randomness of use is poor, and the structure is complex
[0006] Chinese patent CN1692865A "an electric heating pressure device" adopts a rigid connection between the pot cover and the elastic element end, and sets a switch at the displacement end and the static end to be connected in series to the circuit to realize the pressure closed-loop control, but the structure is still complex and the pressure control is reliable. Poor performance, outer pot material consistency, high strength requirements, increased manufacturing cost
[0007] Chinese patent CN2503818 "electric cooker pressure device" controls the switch through the piston rod; and in the adjustable pressure electric cooker technology CN2

Embodiment 1

[0040]The electric pressure cooker is composed of an outer shell 23, an outer pot, an inner pot 20, an electric heating plate, etc. The electric heating plate 21 and the temperature sensing element 22 are fixed to the heat preservation cover 19, the heat preservation cover 19 is connected to the middle plate 17, and the reed tube 18 is directly fixed to the middle plate 17. The middle plate 17 is buckled on the housing 23, and the base 28 is buckled on the housing.

[0041] As shown in Figures 1 to 4, the pressure control device of the electric pressure cooker is installed on the handle, and the pressure control device is a real jump structure.

[0042] In the electric pressure cooker of the present invention, the pressure control device transfers the pressure from the displacement of the gas moving part 6 and the valve core 203 to the lever 5; the core parts of the sudden jump are the elastic element 8 and the lever 5 that rotates at the fulcrum 51. With the rotation of the lever...

Embodiment 2

[0057] As shown in Figure 5, the spool 203 of the control valve and the control valve spring 202 are installed in the valve seat 204. One end of the control valve spring 202 falls on the bonnet 201, and one end is against the control valve spool 203. The middle of the lever 5 is fixed by a The hinge device is hinged, and the fulcrum 51 is the hinge point, so that the lever 5 can rotate around the hinge point. The lever 5 is in the shape of "Z", and the elastic element 8 is an arc-shaped elastic piece. One end is hinged to the handle 1 and one end is fixed to the lever 5. At the bending part of the lever 5, the downwardly extending end of the lever 5 touches the rotating plate 15.

[0058] When the lever 5 is pressed down, the rotating plate 15 can rotate with the lever 5 to drive the magnet 16 to connect to the reed switch 18; or it can move down with the lever 5 to drive the magnet 16 to connect to the reed switch 18.

[0059] The rest is the same as in Example 1

Embodiment 3

[0061] As shown in Figure 7,

[0062] The temperature measuring device is located under the inner pot of the electric pressure cooker. The two ends of the temperature sensing element 26 are wires 261, and the middle of the wires 261 lead wires to electrically connect the two metal sheets 262. The temperature sensing element 26, the connecting wires and the metal sheets 262 are all embedded In the inner support member 40, the inner support member 40 can be a cylindrical plastic member, which is clamped together by two half-cylinders to fix the temperature measuring element 22, the connecting wire 261 and the metal sheet 262.

[0063] The inner support 40 is provided with a cavity in the middle, and a conductive gasket 30 is built in. The conductive gasket 30 contacts the metal sheet 262 when there is no pot. The conductive gasket 30 is fixed on the gasket seat 31, and the gasket seat 31 is cylindrical. , The rod protrudes from the hole in the lower part of the inner cavity. When th...

Abstract

A sudden jump pressure control device belongs to kitchen household electrical appliance technical field. It is located under the handle of electrical cooking utensils (1) and includes steam moving parts (6) and control valve (2), the steam moving parts (6) is installed in liner (7) and slide matching with it, control valve (2)is interlocked with steam moving parts (6),It is also characterized by equipped with flexible element (8), lever (5), rotate plate (15), magnet steel (16) fixed under the rotate plate and the dry spring (18); flexible components (8) pulls the lever, one end of lever which rotates at the fulcrum (51) is located between the lower surface of control valve and the steam moving parts, the other end pulls the rotate plate. The sudden jump pressure control device in the invention has advantages for simple structure, easy assemblage and use, reliable pressure control, swift movement, small amount of drift, high accuracy, low requirements of component materials of control elements and reducing material cost. And it can achieve step regulation through setting the rotate lever equipped in control valve and the cam device of lifter rod.

Description

Technical field [0001] The invention belongs to the technical field of kitchen cooking appliances, and specifically relates to an electric pressure cooker. Background technique [0002] The electric pressure cooker has become one of the indispensable cooking utensils in people's daily life for its energy saving, time saving, convenience and practicality. At present, there are two types of pressure adjustment methods for commercially available electric pressure cookers. One is that the pressure is not adjustable, that is, it can only be used to cook different objects with one stage of pressure; the other is adjustable pressure, which can adjust the appropriate pressure according to the cooking needs. [0003] In the prior art, the pressure control of the pressure cooker is usually through the push rod of the fixed electric heating plate and the elastic touch plate arranged at the lower part of the electric heating plate. This kind of pressure control device ...
