Embodiment Construction

[0037] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] The invention provides a detection method for microwave heating objects based on the combination of ultrasonic and microwave detection, aiming to solve the problem that in current microwave heating equipment, conventional detection means only target the surface of the object and cannot reflect the change of microwave absorption characteristics inside the object.

[0039] Please refer to figure 1 , figure 1 It is a flowchart...

Abstract

The invention discloses a microwave heating method, device and system and a computer storage medium, and the method comprises the steps: obtaining thermoacoustic signals at a plurality of collection points of a heated object in a cooking cavity, and obtaining a microwave loss value corresponding to each collection point; based on the thermoacoustic signals and the microwave loss values at the plurality of acquisition points, obtaining a heating map of the heated object based on dielectric properties at the same time node; and adjusting microwave heating parameters at at least one acquisition point according to the heating map. According to the method, the thermoacoustic effect in the microwave heating process can be utilized, thermoacoustic signals are captured through an ultrasonic sensor, microwave absorption characteristic changes in a heated object are detected, and therefore microwave heating parameters are adjusted according to food changes, and uniform heating is achieved.

Description

technical field [0001] The invention relates to the technical field of microwave heating performance optimization, in particular to a microwave heating method, device, system and computer storage medium. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Microwave heating is widely used in food and related fields due to its high-efficiency heating, instantaneous heating and small thermal inertia. When microwave cooking equipment (such as a microwave oven, etc.) heats food, the microwave cooking equipment generates microwaves, which act on the food placed in the cooking cavity, and the polar molecules or charged particles inside the food interact violently, making polar Sexual molecules / charged particles collide and rub against each other to generate heat to cook food. [0004] In the prior art, after the microwave enters the cooking cavity, it is impossible to heat the...
