[0002] China Patent No. ZL91100026.7 provides a fully sealed automatic multi-functional electric cooking pot, which adopts a "匚" type structure, a pot cover, a sealing ring, a pot body, an electric heating plate, and a flashing switch to form an electric cooking pot. The automatic pressure control mechanism realizes the automatic pressure control of the electric pressure cooking appliance, but since the pressure sensing part is arranged at the bottom of the appliance, the sensed pressure includes the pressure generated by the weight of the pot body, electric heating plate, pot cover and food, while The weight of the food in the pot is constantly changing, so the deviation of the pressure sensing is relatively large, which affects the pressure control accuracy and the cooking effect of the food

Embodiment 1

[0019] Such as figure 1 As shown, in the electric pressure cooking appliance according to Embodiment 1 of the present invention, the pot cover assembly 2 is installed on the top of the pot body 1, and the pot body 1 is equipped with an outer pot 6, and an electric heating plate 3 is installed on the outer pot 6 for putting the food to be cooked. The imported inner pot 7 is placed on the electric heating plate 3, the inner pot cover 4 is provided on the pot cover assembly 2, and the inner pot cover 4 is sealed with the inner pot 7 through the sealing ring 5; the inner pot cover 4 is provided with a pressure sensing valve 9. Including: valve body 91, valve core 92, sealing film 93, valve body 91 is installed on the inner pot cover 4, valve core 92 is installed in the hole of valve body 91, and is a dynamic fit, and valve core 92 and valve body A cylindrical spring 94 is arranged between 93, and the sealing film 93 is installed on the valve body 91, and the sealing film 93 makes ...

Embodiment 2

[0022] The electric pressure cooking appliance of this embodiment is such as figure 2 shown. Wherein, a transmission lever 10 is set up between the spool 92 and the micro switch 8, and the transmission lever 10 can rotate around the shaft 11. When the pressure in the inner pot 7 increases and is greater than the sum of the movement resistance of the spool 92 and the elastic force of the elastic structure, The spool 92 moves upwards, touches the transmission lever 11, the transmission lever 10 rotates around the shaft 11, touches the micro switch 8, and generates an electric signal, thereby adjusting the on-off or heating power of the electric heating plate 3. Other structures are the same as in Embodiment 1.

Abstract

An electric pressure cooker is composed of a main body, a cover unit with internal cover, an internal pot, a sealing ring between internal cover and internal pot, and a pressure control unit arranged on cover unit and consisting of pressure sensing valve and shift detector. Its advantages are high pressure controlling accuracy and high reliability.

Description

technical field [0001] The invention belongs to a daily-use electric cooking appliance, in particular to an electric pressure cooking appliance that can adjust the on-off of the heating device or the heating power according to the pressure change in the pot. Background technique [0002] China Patent No. ZL91100026.7 provides a fully sealed automatic multifunctional electric cooking pot, which adopts a "匚" type structure and a pot cover, a sealing ring, a pot body, an electric heating plate, and a flashing switch to form an electric cooking pot. The automatic pressure control mechanism realizes the automatic pressure control of the electric pressure cooking appliance, but because the pressure sensing part is arranged at the bottom of the appliance, the sensed pressure includes the pressure generated by the weight of the pot body, electric heating plate, pot cover and food, while The weight of the food in the pot is constantly changing, so the deviat...
