Problems solved by technology

But, as mentioned above, because the part structure that needs to fix this kind of agitating fan assembly is more complicated, therefore, not only can increase the kind of part and the number of assembling processes, but also can make the manufacturability decrease and cost increase
In addition, when the stirring fan 23 runs continuously, there are also various failure problems such as the nut 25 or the rivet 27 falling off.
Especially, although the rivet 27 and the bracket 24 that constitute the stirring fan assembly utilize the higher price polytetrafluoroethylene material, in order to stably fix the rivet 27, the curved section at the bottom of the rivet hole 26a on the bracket 24 is difficult to process, Therefore, there is a problem that the manufacturing cost is high

Embodiment Construction

[0011] Such as image 3 As shown, the stirring fan assembly of the microwave oven provided by the present invention mainly includes a supporter 220 , a bracket 240 , a stirring fan 230 and a rivet 270 . Supporter 220 is hollow tubular, and its bottom endoporus is connected on the axle 211 of the rotary motor 210 that runs through furnace chamber 100 bottom surface, and the diameter of its upper end endoporus is larger than the diameter of its lower end endoporus. In addition, the upper end of the supporter 220 has such a thickness that its outer wall can be bent outward by a pressing process. A central hole 241 that can be inserted into and combined with the upper end of the holder 220 is formed through the central part of the bracket 240 , and assembling parts 242 are formed on both sides of the central hole 241 . The inner diameter of the lower end of the central hole 241 is substantially the same as the outer diameter of the lower end of the holder 220, that is, the inside...

Abstract

A stirring fan module for microwave oven is composed of a hollow tubular supporter with one end connected to motor shaft and another end able to be bent ouward, a supporting frame with the central hole for inserting said supporter in it and the installing part with binding holes, a stirring fan between said supporter and supporting frame, and the rivets inserted in said binding holes for fixing the supporting frame to the bottom of cavity.

Description

technical field [0001] The invention relates to a stirring fan assembly of a microwave oven, in particular to a stirring fan assembly of a microwave oven arranged between the shell of the microwave oven and the bottom surface of the oven chamber. Background technique [0002] In general, a microwave oven is a device that uses high-frequency (about 2450MHz per second) microwaves as a heating source to cook food through the frictional heat generated by disrupting the order of food molecules. Such microwave ovens are roughly classified into: a method in which a turntable on which food is placed is rotated in order to uniformly supply microwaves to the food in the cavity; and a system using a stirring fan to uniformly supply microwaves to the food in the cavity. Of course, the above two methods can be used at the same time. figure 1 It is a diagram of the internal partial structure of the microwave oven using the stirring fan mode in the prior art. That is, this microwave oven...
