Microwave oven
A microwave oven has a cooking cavity and an electrical chamber, with a magnetron, a frequency converter assembly and a cooling fan arranged in the electrical chamber. The frequency converter assembly has a mounting support mounted on a bottom plate of the microwave oven, a mounting base obliquely mounted on the mounting support, a frequency converter circuit board mounted on the mounting base and obliquely arranged relative to the bottom plate of the microwave oven, and an air guide cover covering over the frequency converter circuit board for guiding cool air blown by the cooling fan to the frequency converter circuit board. The microwave oven can not only solve the problem that the mounting space for frequency converter circuit boards is not sufficient, but also effectively control the temperature rise of the frequency converter circuit boards.
