heating cooker

Abstract

Disclosed is a heating cooker, comprising: a base (10) formed with a lower electric appliance chamber therein; a cylindrical cavity (20) arranged on the base (10) and formed with a heating cavity (34) for containing food therein, an opening being formed in one side of the heating cavity (34) for accessing food; a semi-cylindrical door body (50) arranged on the cavity (20) and used for closing or opening the opening; an air guide cover (40) arranged in the lower electric appliance chamber; and at least one microswitch (409), the top of the air guide cover (40) being provided with a third mounting position (408) corresponding to the microswitch (409), and the at least one microswitch (409) being arranged on the third mounting position (408). According to the technical scheme, the microswitch (409) is used for controlling the on-off state of an internal circuit of the cooker, and when the door body (50) closes the opening, the internal circuit of the heating cooker is controlled to be automatically disconnected by means of the microswitch (409), so that functions such as automatic power outage of the heating cooker after the door body (50) is opened are achieved, and microwave leakage possibly generated by the heating cooker is prevented, therefore improving the safety coefficient of the cooker.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a heating cooker. Background technique [0002] Usually, such as figure 1 As shown, a heating cooker such as a microwave oven is in the shape of a cuboid, and has a cooking chamber for placing food to be heated and an electrical room for disposing electrical components such as a fan, a power board, a magnetron, and a frequency converter. The heating elements such as the microwave generator and power supply can be cooled by the fan. In addition, in order to fully dissipate heat in the electrical room, it is necessary to ensure a large space in the electrical room. [0003] In addition to the traditional cuboid heating cooker, cylindrical heating cookers have also appeared in the prior art. Cylindrical heating cookers are welcomed by users because of their unique appearance and can provide users with new experiences. In the process of realizing the cylindrical heating cooker,...

AI Technical Summary

Problems solved by technology

In the process of realizing the cylindrical heating cooker, the present inventor found that the existing electric appliance room and its heat dissipation method cannot be directly applied, especially when the structural requirements of the cylindrical heating cooker are relatively compact, it is necessary to re-radiate the heat. and wind guide design

[0004] In addition, for the above-mentioned cylindrical heating cooker, in order to ensure the effective heat dissipation of the electrical components, it is necessary to rationalize the layout of the electrical components, so the electrical components are respectively installed on the upper side and the lower side of the cooking chamber, while the existing heat dissipation and The air guide method cannot meet the heat dissipation requirements of the electrical components on the upper and lower sides of the cooking chamber at the same time
