Method for improving heating uniformity of microwave oven by continuously adjusting position of reflective surface

Abstract

The invention belongs to the technical field of microwave oven control, and discloses a method for improving the heating uniformity of a microwave oven by continuously adjusting the position of a reflective surface. A fixed glass window or plastic window capable of allowing the microwave to pass through is mounted in the microwave oven in the perpendicular or horizontal direction, a cavity with the depth less than 20mm is formed behind the glass window or plastic window, a movable metal reflective surface is arranged at the bottom of the cavity, the moving position of the metal reflective surface is adjusted by an intelligent control system, and the continuous reciprocating motion is conducted, or movement in a certain interval or standstill in a position is conducted. The method solves the problem of uneven microwave heating from the principle, improves the uniformity of microwave heating, and does not change the size of a cooking cavity, the operation is simple, and in addition, themethod can further be combined with an existing metal rotor and a rotating disc to achieve higher heating uniformity.

Description

technical field [0001] The invention belongs to the technical field of microwave oven control, and in particular relates to a method for improving the heating uniformity of a microwave oven by continuously adjusting the position of a reflecting surface. Background technique [0002] Currently, the closest prior art: [0003] With the development of society, the fast-paced lifestyle has led to gradual changes in consumer consumption habits, and people's demand for convenience food is increasing. Many consumers are accustomed to heating food before eating. Household microwave ovens are widely used because of their fast and convenient heating methods, and have gradually become the most important method for secondary heating. Although the heating speed of the microwave oven is fast, the electric field is not uniformly distributed in space due to the standing wave formed by the microwave in the cavity, which leads to uneven heating. In addition, the electric field distribution...

AI Technical Summary

Problems solved by technology

[0006] (1) In the prior art, the problem of uneven microwave heating is not fundamentally solved, and the problem of uneven electric field distribution caused by standing waves is not changed, resulting in poor uniformity of microwave heating

[0007] (2) In addition, whether it is a flat-panel microwave oven or a turntable microwave oven, the food is placed at the bottom of the microwave oven, close to the metal reflective surface at the bottom, which will cause the bottom to be heated too quickly (when the microwave source is at the bottom), or insufficient heating (the microwave source is at the top) Time)

Therefore, its heating effect is limited only by changing the relative position of food and microwave.
