Abstract

The present invention discloses an interference reduction circuit of a refrigerator and a refrigerator. The interference reduction circuit of the refrigerator comprises an electrifying circuit and a power line, the electrifying circuit is provided with a printed circuit board, a compressor and a refrigerator metal base plate in order, a first end of the power line is connected with the printed circuit board, a second end of the power line is connected with the refrigerator metal base plate, the part of line segments of the power line is provided with a metal shielding layer, a first end of themetal shielding layer is connected with the refrigerator metal base plate, and a second end of the metal shielding layer forms a section. The objective of the interference reduction circuit of the refrigerator is to solve the problem that it is difficult for a traditional refrigerator to reduce electromagnetic interference or the occupation space is large and the reliability of the electromagnetic interference reduction is poor when a filter is employed to reduce the electromagnetic interference.

Description

technical field [0001] The invention relates to the technical field of refrigerator circuits, in particular to an interference reduction circuit of a refrigerator and a refrigerator including the interference reduction circuit of the refrigerator. Background technique [0002] Due to the good performance of inverter refrigerators, such as rapid cooling, small automatic temperature adjustment range, and low noise, the market share is increasing. The inverter circuit of the inverter refrigerator has serious electromagnetic interference (EMI) characteristics, and more measures must be taken during design to suppress the interference of the inverter circuit to pass the EMI test. The power cord of the refrigerator in the prior art goes out from the bottom of the refrigerator and then connects to the electric control box of the PCB board, and the electric control box of the PCB board is usually set on the top or back of the refrigerator, so that the power cord and the compressor d...
