Micro-wave oven

Abstract

The invention provides a microwave oven. The microwave oven comprises a shell body, a heating element, an outer shell and a first receding groove; the shell body comprises a top plate located at the top part and a rear plate located at the rear part; the heating element is arranged on the top plate; the outer shell is arranged on the shell body, and the outer shell is in contact with the top of the rear plate; the first receding groove is formed in the top of the rear plate, the first receding groove is located at the position, corresponding to the heating element, of the rear plate, and the first receding groove is arranged in the length direction of the heating element. According to the provided microwave oven, the heating element is located on the top plate of the shell body, the firstreceding groove is formed in the position, corresponding to the heating element, of the top of the rear plate, so that the position, where the first receding groove is formed, of the rear plate is notin contact with the outer shell, in the process that the heat generated by the heating element is transmitted to the outer shell of the microwave oven from the top plate and the rear plate, the heatwhich is transmitted to the outer shell directly through the rear plate is reduced, so that the technical problem that due to the fact that the temperature of the position, in contact with the rear plate, of the outer shell of an existing microwave oven is relatively high, a user is prone to being scalded is solved, and then the temperature of the outer surface of the microwave oven is reduced.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a microwave oven. Background technique [0002] A microwave oven is a common cooking appliance used to cook or heat food, which utilizes microwave energy to heat food placed in a cavity of the microwave oven. Such as figure 1 and figure 2 As shown, currently used microwave ovens with grilling or hot air functions generally set the heating element 50' on the top plate 102' of the microwave oven casing 10', and when the microwave oven with this structure is working, the heating element 50' produces Part of the heat will be transferred to the shell 20' of the microwave oven through the heating element cover 40', the top plate 102' and the rear plate 104', causing the temperature of the shell 20' to rise. Generally, the position where the shell 20' contacts the rear plate 104' The temperature is the highest, which is easy to burn the user and affects the user experience; in order ...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, currently used microwave ovens with grilling or hot air functions generally set the heating element 50' on the top plate 102' of the microwave oven casing 10', and when the microwave oven with this structure is in operation, the heating element 50' produces Part of the heat will be transferred to the shell 20' of the microwave oven through the heating element cover 40', the top plate 102' and the rear plate 104', causing the temperature of the shell 20' to rise. Generally, the position where the shell 20' contacts the rear plate 104' The temperature is the highest, which is easy to burn the user and affects the user experience; in order to reduce the temperature transmitted to the shell 20', the existing microwave oven generally adopts the method of adjusting the working time of the heating element 50', reducing the power of the heating element 50', and reducing the heat transfer rate. Methods such as adding non-conductive materials on the path or increasing mesh holes on the rear plate 104' to reduce the heat transfer area, but these methods will also cause other problems while reducing the temperature, such as: reducing the working time of the heating element 50' and reducing the heating element If the power is too high, the heating of the food will not be in place; the cooling effect of adding non-conductive materials is not obvious, but will increase the steps and costs of assembly; the cooling effect of adding mesh holes on the rear plate 104' is not obvious, etc.
