A wireless power transmission resonator for refrigerator sensor and energy distribution method

Abstract

The invention discloses a wireless electric energy transmission resonator for a refrigerator sensor and an energy distribution method. The wireless electric energy transmission resonator comprises a resonator transmission coil, a resonator receiving coil, a resonator transmission coil compensation capacitor, a resonator receiving coil compensation capacitor, a resonator relay coil and a resonator relay coil compensation capacitor. The resonator receiving coil can be arranged on a random surface of a front surface, a back surface, a left surface, a right surface, an upper surface and a lower surface of a refrigerator along with the sensor. The relay coil is introduced for improving energy efficiency characteristic in middle-distance and long-distance wireless transmission. In consideration of factors such as sensor power requirement in the refrigerator and spatial position, through adjusting the value of a receiving-end resonant matching capacitor, according-to-requirement distribution and effective distribution of energy can be realized. The wireless electric energy transmission resonator for the refrigerator sensor and the energy distribution method have advantages of performing direct electric energy supply to many sensor elements in the refrigerator or charging the battery, improving power supply stability to the sensor, preventing restriction of a power supply and a lead to the sensor, and realizing freer spatial layout.

Description

technical field [0001] The invention relates to a space sensor wireless power transmission technology, in particular to a wireless power transmission resonator for a refrigerator sensor and an energy distribution method thereof. Background technique [0002] The application of electric energy has brought great development to human beings. The traditional way of power transmission is to realize point-to-point direct transmission through metal wires, and power lines have been distributed in every corner of people's lives. Although this inherent wire transmission method plays an irreplaceable role in modern society, it also has problems such as contact sparks, sliding wear, carbon accumulation, and exposed live conductors, which limit the use of wire transmission in some special fields. Application: (1) In chemical industry, mine and other flammable and explosive occasions, the wired method is very easy to cause sparks due to the friction of metal contacts, causing safety accid...
