Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microwave ovens, in particular to a microwave oven and a cavity structure thereof. Background Art
[0002] A microwave oven is a device that generates microwaves through a magnetron after the power is turned on, and irradiates these microwaves on food and other heated objects to cook food. Microwave ovens can also be divided into glass turntable type or flat type for household use according to the way they heat food. Glass turntable type microwave ovens usually have glass turntables, rotating rubber shafts, roller rubber rings and other parts inside the cavity. When the microwave oven is running, the turntable motor drives the shaft to rotate, and the shaft then drives the glass turntable to rotate in the track of the roller. Before using the microwave oven, consumers need to put the shaft and rubber ring into the cavity first, and then put the glass plate on the shaft. After the microwave oven is used, the glass plate, shaft, rubber ring and other accessories in the cavity need to be taken out for cleaning. For consumers, many accessories need to be taken out for cleaning after using the microwave oven, which also causes certain inconvenience to consumers. Compared with the glass turntable type microwave oven, the motor drives the stirrer shaft when it is running, and the stirrer shaft then drives the stirring blade to rotate. This step can disperse the microwaves in the cavity, making the microwave distribution more uniform. However, the cost of materials such as borosilicate glass and stirring blades in flat-panel microwave ovens is relatively high, which will increase the manufacturing cost of the microwave oven.
