Microwave heating device

Abstract

The invention provides a microwave heating device. The microwave heating device comprises a rotatable supporting structure, a second cavity body, a linkage structure and a movable panel, wherein the rotatable supporting structure is arranged at the bottom of the first cavity body; the second cavity body is located in a tank body and is located on one side adjacent to the first cavity body; the linkage structure is arranged in the second cavity body; the movable panel is arranged in the first cavity body, is located between a first side wall and a second side wall and is located at one end, farfrom the first inner side wall, of the supporting structure; and one surface, back to the supporting structure, of the movable panel is connected with the linkage structure, the linkage structure isused for controlling the movable panel to move close to or far from the supporting structure, and then the volume of the first cavity body is correspondingly decrease or increased. The technical scheme of the microwave heating device has the beneficial effects that a heated object can be uniformly heated, and the heating efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of microwave heating, in particular to a microwave heating device. Background technique [0002] With the development of microwave energy utilization technology, the use of microwave is becoming more and more popular. The basic properties of microwave are usually shown as three characteristics of penetration, reflection and absorption. For glass, plastic and porcelain, microwaves almost pass through without being absorbed. And for metal things, microwaves will be reflected. For water and food, it will absorb microwaves and make itself self-heating, which realizes simultaneous heating of the inside and outside of the object, greatly shortens the heating time, improves the heating efficiency, and overcomes the existing heat conduction of the material in the heating process. The method of temperature rise has a long conduction time and energy consumption in the conduction medium. [0003] However, in the ap...

Problems solved by technology

For water and food, it will absorb microwaves and make itself self-heating, which realizes simultaneous heating of the inside and outside of the object, greatly shortens the heating time, improves the heating efficiency, and overcomes the existing material in the heating process obtained by heat conduction through the medium. The method of temperature rise has a long conduction time and energy consumption in the conduction medium

[0003] However, in the application of microwave heating, there is a problem of poor heating uniformity of the object to be heated. In order to solve this technical problem, a rotatable tray is usually installed in the cavity of the microwave heating device, and the object to be heated is placed on the tray. Although it can improve the uniformity of heating to a certain extent, there is still uneven heating at different radius positions of the tray, and at the same time, the overall temperature of the object to be heated still has a problem of slow rise when heated
