Microwave cooking equipment and control device thereof

Abstract

The invention discloses microwave cooking equipment and a control device thereof, wherein the microwave cooking equipment comprises a cavity. A microwave heating part is arranged in the cavity. The control device comprises a power divider, a control circuit, a microwave source and a power source. An input port of the power divider is connected with the microwave source, and an output port is connected with the microwave heating part, or the input port of the power divider is connected with the microwave heating part, and the output port is connected with the microwave source. The power divideris used for conducting power division or power synthesis on microwaves output by the microwave source. The control circuit is used for controlling the microwave source to output the microwaves according to given power, and the microwaves output by the microwave source are transmitted to the microwave heating part through the power divider so as to heat food in the cavity. According to the controldevice, through the power divider, power division and power synthesis can be both achieved so as to heat the food, thus the cooking speed can be increased, and cooking experience of a user is promoted.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a microwave cooking device and a control device thereof. Background technique [0002] Microwave is a kind of electromagnetic wave, and microwave oven is a kind of modern microwave cooking equipment that uses microwave to heat food. A microwave oven consists of a power supply, a magnetron, a control circuit, and a cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves and couples the microwaves into the cavity to heat the food in the cavity. [0003] It can be seen that the existing microwave ovens use magnetrons to emit microwaves for microwave heating, and only for heating, which may result in slow microwave cooking speed and affect the cooking experience of users. Furthermore, how to accurately control the microwaves of the desired power emitted by the...

Problems solved by technology

[0003] It can be seen that the existing microwave ovens use magnetrons to emit microwaves for microwave heating, and can only be heated, which may lead to slow microwave cooking speed and affect the user's cooking experience

Furthermore, how to accurately control the microwaves of the desired power emitted by the magnetron is very important for microwave ovens to heat food. However, there is no device on the existing microwave ovens to accurately detect the microwaves emitted by the magnetron, so it is difficult Accurate and effective heating control for different foods
