Embodiment Construction

[0028] like figure 1 As shown, the electric rice cooker includes a shell 1, an outer pot 2, an inner pot 3, a pot cover 4, a heating element 8 and a control circuit. The outer pot 2 is located in the shell 1 and connected with the shell 1. There is a layer of heat insulation layer 5 between the outer pot 2 and the shell 1, and the heat insulation layer 5 plays a role of heat insulation. After the pressure in the pot reaches the set value, the heating element 8 stops heating, but the inner pot 3 can maintain a higher temperature through the heat insulation layer 5, which is equivalent to keeping the food in the pot in a heated state to achieve the effect of energy saving. Heat insulating layer 5 is usually made of thermal insulation material.

[0029] Similar to the common electric cooker, the inner pot 3 is directly placed in the outer pot 2 . The hinge of pot cover 4 is positioned at the upper edge of outer pot 2. In this embodiment, the fastening device includes a button...

Abstract

The present invention relates to an electric cooker. It comprises external shell, external cooker, internal cooker, cooker cover, heating element and control circuit. The cooker cover is hinged on the upper edge of external cooker, between the cooker cover and external shell a fastening device is mounted, in the cooker cover a pressure control device is placed, and in the pressure control device a control switch which can utilize internal pressure of the cooker to make control is mounted, and said control switch is connected in the above-mentioned control circuit. Said electric cooker utilizes the pressure control device to make detection and make control switch act to implement stopping heating. Said electric cooker is safe, reliable and small in power consumption.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, in particular to an electric rice cooker. Background technique [0002] Existing common electric cooker is made up of parts such as shell, outer pot, inner pot and heating element, and its control circuit is realized by a temperature controller. Specifically, when the temperature in the inner pot reaches the set value, the thermostat disconnects the control circuit, and the heating element stops heating. [0003] However, due to the low sensitivity of the temperature controller, there is a certain deviation in the control of the temperature, which affects the actual cooking effect. [0004] In addition, the heat preservation of the existing electric rice cooker is realized through a heat preservation circuit. That is to say, when the temperature of the inner pot drops to a certain level, the heat preservation circuit is turned on, so that the heating element is...
