Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microwave cooking devices, in particular to a microwave stirrer for a microwave cooking device. BACKGROUND

[0002] When the microwave cooking device is heated, due to the propagation characteristics of microwaves and factors such as the shape, size and density of food, the food may be unevenly heated.

[0003] In order to improve the heating uniformity, a microwave stirrer is arranged at the microwave inlet of the microwave cooking device. The microwave stirrer periodically changes the load state of the magnetron through its own rotation stirring, causing the operating frequency to periodically change within a frequency domain, improving the uniformity of the microwave field distribution in the cooking device and improving the uniformity of microwave heating.

[0004] In the prior art, the stirring motor of the microwave stirrer is connected and driven with the stirring shaft through the motor shaft clamp or the stirring shaft. The driving effect of the stirring motor can be guaranteed by the close cooperation of the driving connection, but the assembly is not convenient. Or the stirring motor drives the stirring shaft through the stirring shaft by the lever on the motor shaft. The driving effect of the stirring motor is affected by the lack of mutual support of the lever and the clamp spring, which can easily deform and shift, affecting the accuracy and stability of the contact. Therefore, there is currently a lack of a stirring device that is convenient to assemble and has mutual support for cooperation to ensure the driving effect of the stirring motor on the stirring shaft.
