Convective motor unit of microwave oven

Abstract

The convective motor assembly for microwave oven is installed vertically on the heating chamber, and includes fixing part with coil, rotating part, rotating shaft connected to the lower end of the rotating part, bracket with bearing for the rotating shaft, lubricating sheet of teflon and film spacer between the rotating part and the bracket.

Description

technical field [0001] The present invention relates to a microwave oven, more specifically, to a convection motor assembly for a microwave oven which utilizes a convection motor to circulate heat from a heater provided inside the microwave oven. Background technique [0002] In microwave ovens with microwaves as the main heat source, in order to solve the problem of single heat source due to microwave heating alone, microwave ovens with heaters inside have recently appeared. Such as figure 1 As shown, a heater 4 is arranged above the heating chamber 2 . In addition, on one side of the upper part of the heating chamber 2, a convection motor assembly 10 for circulating air is provided, which can circulate the air in the direction of the arrow shown in the figure. [0003] That is, the convection motor assembly 10 sucks the air inside the heating chamber, makes the air flow through the heater 4 , and returns the hot air (air heated by the heater) back into the heating chambe...
