Microwave oven and control method thereof

Abstract

The invention discloses a microwave oven, comprising an oven body with a cooking cavity formed therein. Slideway plates are fixedly arranged on a front part and a rear part of two external broadsides of sidewalls of the cooking cavity respectively; through holes allowing a hook to extend into the cooking cavity are arranged correspondingly on the slideway plates and sidewalls of the cooking cavity; hooks of an upper level grill are fixedly connected with support bars; hooks of a lower layer grill are fixedly connected with hollow support columns, wherein the hollow support columns confine the support bars, which are capable of sliding freely up and down, in the cavities thereof; a supporting plate can move up and down along the slideway plates by effect of a driving motor; pressure transducers are arranged on the supporting plate and under the hollow support columns. The invention also discloses a control method of the microwave oven. The microwave oven provided by the invention can automatically sense weight of food to be heated, then automatically select heating power and time according to the measured weight and a built-in algorithm, so as to realize one-time operation of a user.

Description

technical field [0001] The invention relates to a microwave oven, in particular to an intelligent microwave oven with a gravity sensor capable of automatic cooking. Background technique [0002] A microwave oven is a device that generates microwaves from an electric current and irradiates the microwaves to the surface of the object to be heated in the cavity to heat the object. As everyone knows, microwave oven is a kind of modern cooking stove that heats food with microwave. The microwave it uses is a kind of electromagnetic wave. The energy of this electromagnetic wave is not only much greater than that of ordinary radio waves, but also has special characteristics. When the microwave hits metal, it will reflect, and the metal has no way to absorb or conduct it; microwave can pass through insulation such as glass, ceramics, and plastics. Materials, but will not consume energy; and food containing water, not only can not pass through the microwave, but its energy will be a...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, during the operation of microwave ovens, it is often necessary to know the weight of the food to be processed, and to select the heating power and heating time according to the weight. However, it is difficult for ordinary users to weigh the food before heating, and it is impossible to know the weight of the food to be heated. Weight, which leads to the performance of the microwave oven can not be fully exerted, resulting in insufficient or excessive heating, affecting the user experience
