If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

A compressor is the heart of a refrigeration appliance, which is a driven fluid machine that raises low pressure gas to high pressure gas. The refrigerating cycle is powered by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the exhaust pipe.

In the compressor, the accumulator is an important component, is assembled at the air conditioner evaporator and the suction pipe of the compressor, and is a protective component for preventing liquid refrigerant from flowing into the compressor to generate liquid impact. During the operation of the air conditioning system, the refrigerant can not be completely vaporized; namely, the liquid refrigerant can enter the liquid storage device from the refrigerant coming out of the evaporator, the liquid refrigerant which is not vaporized can directly fall on the cylinder bottom of the liquid storage device because the refrigerant is heavier than gas, and the vaporized refrigerant enters the compressor from the outlet of the liquid storage device, so that the liquid impact caused by the liquid refrigerant sucked by the compressor is prevented.

On the one hand, in order to reduce the cost of reservoir, the casing wall thickness of attenuate reservoir under the precursor that guarantees withstand voltage, perhaps adopt spinning formula reservoir to replace traditional syllogic reservoir, all are one of present solution, but above-mentioned two kinds of modes all can lead to the weight of reservoir to become light for the inertia of reservoir reduces by a wide margin, and the reservoir vibration worsens obviously, influences the use.

On the other hand, the accumulator is susceptible to vibration of the compressor. For example, in a rotary type refrigeration compressor, which is a displacement type compressor in which a working volume is rotated, gas compression and pressure change are performed by volume change, and the volume change is achieved by rotating one or more rotors of the compressor in a cylinder, unlike a reciprocating compressor, the volume of the rotary type refrigeration compressor is periodically enlarged and reduced while a spatial position is continuously changed, and basic working processes such as suction, compression, and discharge can be performed as long as a suction port and a discharge port are reasonably arranged in the cylinder. In the in-process of compressor operation, because one or several rotors of compressor at the cylinder internal rotation for compressor itself vibrates, and the noise production, the vibration can transmit the reservoir through the part that compressor main part and reservoir are connected, makes reservoir self produce the vibration, forms resonance with the compressor main part, can make the noise increase, still can influence the life of compressor simultaneously, therefore the resonance of reservoir, the noise of reduction compressor need be eliminated.

In order to reduce the noise of the compressor during operation, in the related art, the compressor is generally fixed to the mounting base plate of the compressor through the elastic foot pad, which can reduce the vibration and noise of the compressor during operation to a certain extent, but the noise and vibration of the compressor during operation are still large and the installation is inconvenient.

Based on the liquid storage device assembly, the compressor assembly and the refrigeration equipment, the vibration condition of the compressor can be effectively improved, the vibration noise is reduced, and the installation is convenient.

It can be understood that the upper cup 101, the main cup 102 and the lower cup 103 of the spinning type liquid accumulator are integrally formed, that is, the cup of the liquid accumulator is a metal cylinder, and two ends of the metal cylinder are extruded and formed. Specifically, a metal cylinder with a proper inner diameter is selected according to actual requirements, then the two ends of the metal cylinder are extruded, so that the inner diameters of the two ends of the metal cylinder are narrowed to form an upper cup body 101 and a lower cup body 103, and a main body of the metal cylinder is reserved as a main cup body 102, so that the upper cup body 101, the main cup body 102 and the lower cup body 103 are integrally formed. Meanwhile, after the openings at the two ends of the metal cylinder are extruded, an exhaust hole in butt joint with the exhaust pipe 104 and an air suction hole in butt joint with the air suction pipe 105 are respectively formed.

In addition, the exhaust pipe 104 and the lower cup 103 may be connected together by a CMT (cold metal transfer technology) welding process, the CMT welding process uses two sets of front and rear cooperating wire feeding mechanisms to make the feeding process of the welding wire be intermittent wire feeding, the rear wire feeding mechanism feeds the welding wire forward at a constant wire feeding speed, the front wire feeding mechanism controls the pulse type wire feeding at a frequency of Hz according to an instruction of the control system, the digital welding control system can automatically reduce the welding current according to the starting time of arc generation until the arc is extinguished, and adjust the middle pulse type wire feeding, after the molten droplet drops from the welding wire, the digital control system increases the welding current again, further sends the welding wire forward, and then regenerates the welding arc to start a new round of welding process. This alternating "cold-hot" greatly reduces the generation of welding heat and reduces the conduction of welding heat in the welded parts.
