Temperature measurement microwave oven and work control method thereof

Abstract

The invention relates to a temperature measurement microwave oven and a work control method thereof. The temperature measurement microwave oven comprises a microwave heating cavity used for containing an object to be heated and a non-contact type temperature detection device used for detecting the temperature of the object to be heated. A flat plate used for storing the object to be heated is arranged in the microwave heating cavity. An open pore is formed in the annular wall of the microwave heating cavity. The non-contact type temperature detection device comprises a detection probe, and the detection probe right faces the open pore or is located in the open pore. The temperature measurement microwave oven is characterized in that a cooling fan capable of cooling the non-contact type temperature detection device is arranged beside the non-contact type temperature detection device. Compared with the prior art, the temperature measurement microwave oven and the work control method thereof are advantageous in that the cooling fan can prevent the working temperature of the non-contact type temperature detection device from being excessively high and can also blow away lampblack and steam nearby the non-contact type temperature detection device when food is heated by the microwave oven, and thus lampblack and steam condensation is unlikely to happen on the surface of a driving motor of the non-contact type temperature detection device in the long-time use process.

Description

Technical field [0001] The invention relates to a temperature measuring microwave oven and a working control method thereof. Background technique [0002] A microwave oven is a device that generates microwaves by a magnetron after the power is turned on, and irradiates these microwaves on the food to be heated to cook the food. The microwave oven uses the principle of alternating electromagnetic field to produce high-frequency motion in the cavity of the microwave oven to heat the food by the principle of high-speed and intense friction between molecules and molecules to generate heat. The microwave should be avoided when the microwave oven is working, because the human body can also absorb microwaves. Once the human body is exposed to microwave radiation, it will have an adverse effect on health. [0003] In recent years, people have paid more and more attention to healthy eating. As a microwave oven with a high daily usage rate, although it can quickly heat food, the result of ...

AI Technical Summary

Problems solved by technology

[0004] For the technology of real-time detection of the temperature of the heated food in the microwave oven, in order to ensure safety and stability, a non-contact temperature detection device is often used, and the detection probe of the non-contact temperature detection device is often installed in the microwave oven. Inside or outside the ring wall of the heating cavity, and aligned with the flat plate of the object to be heated in the microwave heating cavity, then when the non-contact temperature detection device is working in the microwave oven, its temperature will increase with the increase of the temperature of the microwave heating cavity, and the surface It will also condense the oil fume and water vapor generated in the microwave heating chamber, which will greatly affect the reliability of its work; in addition, when installing the detection probe, it is often necessary to open a hole on the back plate of the microwave chamber, and this opening will not be used in actual use. , will cause microwave leakage
