A temperature-measuring microwave oven and its working control method

Abstract

The invention relates to a temperature-measuring microwave oven and its working control method, wherein the temperature-measuring microwave oven includes a microwave heating cavity for placing an object to be heated, and a non-contact temperature detection device for detecting the temperature of the object to be heated. There is a flat plate for placing the object to be heated in the cavity, and an opening is provided on the ring wall of the microwave heating cavity, and the non-contact temperature detection device includes a detection probe, which is facing the opening or is located in the opening. In the hole, it is characterized in that: the non-contact temperature detection device is installed on a rotating seat, the rotating seat is connected with a driving motor and driven by the driving motor to rotate, so that the non-contact temperature detecting device can follow the rotation of the rotating seat Turn and turn. Compared with the prior art, the present invention has the advantage that the temperature detection range of the detection probe to the object to be heated in the microwave heating chamber can be enlarged, thereby better ensuring the accuracy and heating effect of the heating temperature of the detected object to be heated .

Description

Technical field [0001] The invention relates to a temperature measuring microwave oven and a working control method thereof. Background technique [0002] The microwave oven is a device that generates microwaves by the magnetron after the power is turned on, and irradiates the microwaves on the food to be heated to cook the food. The microwave oven uses the alternating electromagnetic field of the food molecules to be cooked in the microwave oven cavity to produce high-frequency motion, and the principle of high-speed and violent friction between molecules to heat the food. When the microwave oven is working, avoid the leakage of the generated microwaves, 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 ...

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. Outside or inside the ring wall of the heating chamber, align with the flat plate of the object to be heated in the microwave heating chamber; however, in many cases, the volume of the object to be heated on the plate is often large, and the detection range of the fixed detection probe will be limited, which will cause Further affect the controller's control of the heating magnetron, which in turn will affect the taste of the temperature accuracy of the heated object

In addition, when installing the detection probe, it is often necessary to open a hole on the rear plate of the microwave chamber. This opening will cause microwave leakage during actual use.
