Stirring Assembly and Microwave Oven

Abstract

The invention provides a stirring assembly and a microwave oven. The stirring assembly comprises a stirring sheet, a stirring shaft, a stirring support and a stirring motor. An installation hole is arranged in the stirring sheet. The stirring shaft comprises a first shaft section and a second shaft section. A top shaft shoulder is formed at the joint of the first shaft section and the second shaft section. A shaft hole is axially arranged in the upper end of the stirring shaft. The stirring support sleeves the stirring shaft and is fixed on a base plate of the microwave oven. The lower end of the stirring shaft is fixed on a motor shaft of the stirring motor. The upper end of the stirring shaft penetrates through the installation hole so that the stirring sheet is installed on the first shaft section and abutted against the top shaft shoulder. A cone-shaped device can be inserted into the shaft hole from the upper end of the stirring shaft and be stamped downwards so that the upper end of the first shaft section expands and bends towards the outer side to form a limit flange is formed, so the stirring sheet is fixed on the stirring shaft and the stirring motor is allowed to drive the stirring shaft to drive the stirring sheet to rotate. By use of the stirring assembly, the stirring sheet can be firmly fixed on the stirring shaft, working processes are simple and production efficiency is high.

Description

Technical field [0001] The present invention relates to the field of cooking appliances, and more specifically, to a stirring assembly and a microwave oven including the stirring assembly. Background technique [0002] At present, microwave ovens on the market use the following methods in order to distribute microwaves evenly on the food: one is that the microwave cavity is equipped with a turntable, and the food is placed on the turntable. The turntable depends on the turntable when the microwave is working. The motor drives the rotation; the other is that there is no turntable in the cavity of the microwave oven. When the microwave oven is working, the food is placed on the inner partition and the stirring motor drives the stirring plate to rotate to evenly spread the microwave on the food; there are also the above two Combination of microwave ovens. [0003] Such as figure 1 As shown, it is a schematic diagram of the internal structure of the above-mentioned microwave oven adop...

Problems solved by technology

[0004] The disadvantage of the prior art is that in order to use nuts to fix the stirring plate on the stirring shaft, it is necessary to tap the screw on the top of the stirring shaft, which makes the production of the stirring shaft and the assembly of the stirring components very cumbersome, and the number of assembly parts is large and the processing of parts is difficult. The cumbersome process is very unfavorable to production efficiency and processing costs; and every time the stirring motor is powered off and re-energized, the rotation direction of the stirring motor shaft will change, and there is only one fixed direction of the nut, so half of the time when the microwave oven is working is to stir the motor shaft The rotation direction of the microwave oven is the same as that of the nut fixing direction, so that as the use time increases, the nut will loosen, which will cause the stirring plate to catch fire, the inner partition to focus, and fire, etc., which will seriously affect the safety of the microwave oven.
