Intelligent control system for improving microwave heating efficiency and control method thereof

Abstract

The invention discloses an intelligent control system for improving the microwave heating efficiency and a control method thereof. The intelligent control system comprises a microwave oven cavity andan oven door. The microwave oven cavity is equipped with a solid-state source power amplifier for generating microwave power. The solid-state source power amplifier is connected with a radio frequencyantenna and feeds microwave energy through the radio frequency antenna. A driving device, a transmission device and an MCU controller are arranged to the side of the radio frequency antenna. The MCUcontroller is connected with the driving device, the driving device is connected with the transmission device, and the transmission device is connected with the radio frequency antenna. The MCU controller controls the on-off of the driving device to drive the transmission device to move, so as to drive the radio frequency antenna to move. The electromagnetic field distribution in the cavity is changed by adjusting the relative positions of the radio frequency antenna and the inner wall of the microwave oven cavity, so as to obtain optimal food load matching and optimal transmission efficiency.Through the scheme of the invention, the heating efficiency of the microwave oven can be improved intelligently, and energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of microwave heating, in particular to an intelligent control system and a control method for improving microwave heating efficiency. Background technique [0002] Traditional microwave ovens use a magnetron to generate microwave energy, which is coupled to a waveguide and then transmitted to the cavity to heat the food. The output power of the magnetron is constant. When the food load does not absorb the food well, it will generate a large reflected power, which is harmful to the magnetron. The cathode of the tube is damaged, and this part of the reflected power is converted into heat loss, which is a great loss to the energy conversion efficiency. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an intelligent control system and control metho...
