Detailed Description

For fully understanding the objects, features and technical effects of the present invention, the following detailed description is given by way of example with reference to the accompanying drawings, and the following is a detailed description of the present invention:

as shown in fig. 2 to 4, the electric rice cooker of the present invention includes an upper cover 4 and a cooker body (not shown), the upper cover 4 is connected to the cooker body through a pivot structure, and a lock catch 44 is disposed at an end portion far away from the pivot structure, so that a user can open or close the electric rice cooker as desired.

The utility model discloses a kind of deep pot body includes shell, a kind of deep pot seat, sets up the control unit in the shell. The cooker body is provided with a cavity which can contain an inner container of the electric cooker for cooking. A heating device is arranged between the inner container and the wall of the containing cavity. The heating device may be a heating plate disposed at the bottom of the cavity, or may be a heating device disposed on the wall of the cavity, and is not limited by this embodiment. The heating device not only can make food be heated and cooked, but also can be matched with the upper cover of the electric cooker to implement the function of keeping the temperature in the cavity within the set range. Therefore, the heating device has two starting times: firstly, starting when a user operates a control panel to trigger a cooking task; secondly, in the automatic heat preservation task after the cooking task is finished, heating is started when the temperature in the containing cavity is lower than a temperature value set by the electric cooker.

Therefore, the heating device is a part of the heat preservation device of the electric rice cooker.

The upper cover 4 of the rice cooker comprises a surface cover 43, a control panel 42 arranged on the surface cover 43, an inner cover 41 arranged inside the surface cover, and a steam valve (not shown) arranged on the inner cover 41.

The inner cover 41 is formed by injection molding directly and integrally, and a plurality of fasteners are arranged around the periphery thereof to be fastened with the surface cover 43. The end of the inner lid 41 away from the pivoting body structure is provided with a latch 44, and the latch 44 is connected with an elastic member, further, the elastic member may be a spring, so as to facilitate the user to open or close the upper lid of the electric rice cooker. The side of the inner lid 41 facing the pot body cavity has a first recess 412 in which the temperature sensing element 5 and the steam valve (not shown) are located. Further, a second recess 413 deeper than the first recess 412 may be further disposed on the inner lid 41 for placing the steam valve, so that the surfaces of the temperature sensing element 5 and the steam valve are not higher than the openings of the first recess 412 and/or the second recess 413, thereby keeping the two components clean.

The inner lid 41 is provided with an opening 411, and the opening 411 is located above the position of the steam valve. The surface cover 43 is provided with a through hole 431 matched with the opening 411, the through hole 431 is provided with an annular wall extending towards the opening 411 and extending into the opening 411, and then is communicated with the opening 411 to form an air passage, so that the cavity positioned in the cooker body is subjected to air exchange with the outside through the air passage.
