Assembling structure of microwave oven

Abstract

An assembling structure for microwave oven is composed of an empty cavity with cooking chamber, base plate as the bottom of microwave oven, casing surrounding said empty cavity, front frame and back frame. It features that the holes on the bottom of front frame and the lugs on the bottom of back frame are respectively matched with the lugs at front end of base plate and the holes at back end of base plate. Its advantages are easy assembling, less screws, and high stability.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a simple assembly structure between parts of the microwave oven. Background technique [0002] Generally speaking, a microwave oven is an electrical device that uses high-frequency waves (about 2,450 MHz per second) as a heating source to cook food by breaking the order of food molecules and causing frictional heat generated by high-speed oscillation of molecules. [0003] Such as figure 1 As shown, such a microwave oven is generally composed of a casing 10 forming the outer surface, a base plate 20 forming the bottom surface, a cavity 30 with a cooking chamber, and a microwave oven door 40 for opening and closing the cavity. [0004] The aforementioned housing 10 surrounds a cavity 30, which protects the cavity from the external environment. [0005] A front frame 50 and a rear frame 60 are respectively arranged at the front and rear of the cavity 30 , which are combined with the casing 10 ...

AI Technical Summary

Problems solved by technology

[0014] As described above, the assembly structure of the existing microwave oven requires many screw connections, so the manufacturing process is very complicated, thereby causing problems such as an increase in the overall production cost.

[0015] Not only that, if the screw is lost due to the screw disengagement during the use of the microwave oven, the stable combination of the microwave oven cannot be guaranteed, and vibration caused by the drive of the motor (not shown) will occur

[0016] It is particularly worth noting that the assembly structure of existing microwave ovens does not consider the relative movement in the up-and-down direction and the relative movement in the front-to-back direction between the various components, resulting in misalignment between the screw connection holes, which brings difficulties to assembly

The above-mentioned assembly is realized through several screw connections, and the overall assembly efficiency is not ideal
