Embodiment 1

[0015] Embodiment 1: An electric heating pressure cooking device for kitchen, see accompanying drawing 1, including outer cover 1, inner cover 2, sealing ring 3, inner pot 5, outer shell 7, heating plate 8, pressure receiving plate 20, switch 11, control circuit etc. The pressure-receiving piece 20 described in this embodiment is an elastic diaphragm, which is installed on the inner cover 2 , and the switch 11 is installed on the outside of the inner cover 2 at a position corresponding to the pressure-receiving piece 20 .

[0016] Its working process is: when the pressure in the pot rises, the gas pressure pushes the pressure-receiving piece 20 to deform and make it protrude outward. When the pressure is high enough, the pressure-receiving piece 20 directly touches the switch 11. At this time, the control circuit controls the heating Disc 8 is powered off and stops heating. The pressure in the pot begins to decrease gradually. When the pressure in the pot drops to a certain l...

Embodiment 2

[0017] Embodiment 2: An electrothermal pressure cooking device for kitchen, see accompanying drawing 2, including outer cover 1, inner cover 2, sealing ring 3, inner pot 5, outer shell 7, heating plate 8, pressure receiving plate 20, switch 11, Lever 17, control circuit etc. are formed. The pressure-receiving piece 20 described in this embodiment is a rigid sheet, which is installed inside the inner cover 2 through an elastic sealing ring 14, and a thimble 10 is fixed on the outside of the pressure-receiving piece 20, and the upper end of the thimble 10 passes through the inner cover 2. A lever 17 is provided between the upper end of the thimble 10 and the switch 11 .

[0018] Its working process is: when the pressure in the pot rises, the gas pressure pushes the pressure-receiving piece 20 to move upward, compresses the elastic sealing ring 14, and at the same time drives the thimble 10 to move upward. When the pressure is high enough, the thimble 10 triggers the switch throu...

Embodiment 3

[0021] Embodiment 3: An electrothermal pressure cooking device for kitchen, see accompanying drawing 3, including an outer cover 1, an inner cover 2, a sealing ring 3, an inner pot 5, an outer shell 7, a heating plate 8, a pressure receiving plate 20, a switch 11, Lever 17, adjustment spring 15, control circuit etc. are formed. The pressure-receiving piece 20 described in this embodiment is a rigid sheet, which is installed inside the inner cover 2 through an elastic sealing ring 14, and a thimble 10 is fixed on the outside of the pressure-receiving piece 20, and the upper end of the thimble 10 passes through the inner cover 2. A lever 17 is provided between the upper end of the thimble 10 and the switch 11, and a pressure adjustment knob 13 is provided on the inside of the outer cover 1 at a position corresponding to the thimble 10 or the lever 17, and the pressure adjustment knob 13 is connected to the outer cover 1. The caps 1 are threadedly connected, and an adjustment spr...

Abstract

The electrically heated pressure cooker includes an outer cover, an inner cover, a sealing ring, an inside pan, an outer casing, a heating disc, a pressed elastic plate, a switch, a control circuit, etc. It can form one pressurized cooking cavity; one electrically insulating, heat insulating and protecting shell; and one cooking control mechanism with the control circuit, the pressed elastic plate and the switch. The present invention has the advantages of simple structure, low cost, reliable operation, high control precision, etc.

Description

technical field [0001] The invention belongs to an electric heating pressure cooking device for kitchens, and relates to an electric heating pressure cooker. Background technique [0002] In the Chinese market, there are already electric heating device products that adopt a pressure control scheme to control the pressure in the pot. Between the pot body and the pot cover, the combination of the pot body, pot cover and sealing ring is installed in the "["-shaped bracket. When the pressure inside the pot rises, a slight relative displacement occurs between the pot cover and the pot body. After feeling the displacement, the [”shaped bracket triggers the control circuit to adjust the working state of the heating device, thereby realizing automatic control. The disadvantages of the existing scheme are that its structure is complex, the processing and assembly of parts are difficult, and the precision of pressure control is low. Contents of the invention [0003] The purpose o...
