Document Type and Number:
WIPO Patent Application WO/2017/096779
Kind Code:
A1
Abstract:
A microwave oven comprises a cooking cavity (10) and an electrical chamber (11), and the electrical chamber (11) is provided with a magnetron (12), a variable-frequency drive assembly (13), and a cooling fan (14). The variable-frequency drive assembly (13) comprises: a mounting support frame (131) mounted on a base plate (15) of the microwave oven, a mounting base (132) inclinedly mounted on the mounting support frame (131), a variable-frequency drive circuit board (133) mounted on the mounting base (132) and inclinedly disposed with respect to the base plate (15) of the microwave oven, and an air guide cover (134) covering over the variable-frequency drive circuit board (133). The air guide cover (134) is configured to guide cool air generated by the cooling fan (14) to flow to the variable-frequency drive circuit board (133). The microwave oven can address the problem in which the variable-frequency drive circuit board (133) does not have a sufficient mounting space, and effectively controls a temperature increase of the variable-frequency drive circuit board (133).
