Fixing structure of transformer for microwave oven

Abstract

The invention discloses a fixing structure of a transformer for a microwave oven. The microwave oven comprises an upper panel, a bottom panel arranged under the lower end of the upper panel, a front panel arranged at the front end of the upper panel, and a rear panel arranged at the rear end of the upper panel. An oven chamber and an electronic component chamber are arranged in a space formed through the upper panel, the bottom panel, the front panel and the rear panel, wherein the oven chamber is provided with an oven door. A fixing structure is welded on a sidewall of a transformer and comprises a fixing base, wherein a connecting hole is provided in the centre of the fixing base, and multiple equally distributed support arms are provided on the outer annular side surface of the fixing base. Through the fixing structure of the invention, housing vibration frequency of a microwave oven with the fixing structure can be reduced by more than 70% and noise is reduced greatly. Simultaneous, a magnetic field leakage of a transformer is reduced and a heat dissipation area is increased and is beneficial for heat radiation.

Description

technical field [0001] The invention belongs to a microwave oven device, in particular to a fixed structure for a transformer used in a microwave oven, which can directly contact the transformer with the shell of the microwave oven, reduce the vibration and noise of the shell of the microwave oven, and reduce the magnetic field leakage of the transformer. Background technique [0002] In general, a microwave oven is a device that cooks food by irradiating a heated object such as food with microwaves generated by a magnetron after power is turned on. Such microwave ovens are classified into domestic microwave ovens equipped with small magnetrons and commercial microwave ovens equipped with large or multiple magnetrons. Microwave ovens can also be distinguished according to the method of heating food. Household microwave ovens generally use a glass plate method that rotates food, and commercial microwave ovens mainly use a stirring fan method that disperses microwaves. Commer...

AI Technical Summary

Problems solved by technology

[0007] However, the transformer in the microwave oven of the prior art is only fixed to the bottom panel by four screws on the bottom plate, the connection is not firm enough, and the magnetic field of the transformer leaks, causing relatively large vibrations and noises on the microwave oven shell.
