Valve group component and compressor and refrigerator with same

Abstract

The invention provides a valve group component and a compressor and a refrigerator with the same. The valve group component comprises an inlet valve sheet and a valve plate, wherein the inlet valve sheet comprises a valve sheet body and inlet valves, and the inlet valves correspond to suction inlets in the valve plate and can close or open the suction inlets; each inlet valve comprises a head part and an arm part, and the arm part comprises a root part and a waist part; a necking structure is formed on the waist part; the necking structure has smaller width and larger length, so that the lifting height of each inlet valve is increased, enough effective flow area is ensured, and the high-frequency refrigerating capacity is increased; the inlet valves comprise the first inlet valve, the second inlet valve and the third inlet valve which are arranged in sequence and are different in rigidity and inherent frequency, the response speed is increased, the low-frequency performance and the high-frequency cooling capacity are considered, and the better air suction efficiency can be achieved; excellent performance is guaranteed during low-frequency operation of the compressor, and higher-displacement refrigerating capacity of the fixed-displacement compressor can be realized during high-frequency operation of the compressor; and the root of each inlet valve is connected with the valve sheet body, stress distribution is improved, and vibration noise is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerator equipment, and in particular relates to a valve group assembly, a compressor and a refrigerator having the same. Background technique [0002] The suction efficiency of the compressor is related to the structure of the suction valve group. The existing valve group mostly adopts a single suction valve with high reliability, but the heavy head and the short and fat arm of the suction valve are not suitable. , so that when the compressor is running at high frequency, the response speed of the suction valve is slow, and the opening and closing of the suction port is delayed, resulting in the phenomenon of refrigerant backflow, which greatly restricts the energy efficiency of the compressor. It was proposed to use a valve group assembly with three suction valves. The natural frequencies of the three suction valves are different, which can adapt to the operation of the compressor in different frequ...
