Problems solved by technology

[0003] The existing liquid receiver is set between the evaporator and the compressor, such as figure 1 As shown, the gas-liquid two-phase refrigerant enters the transition pipe 02 from the capillary tube 01, flows through the evaporator 03 and enters the accumulator 05 through the conduit 04, and when the refrigerant in the accumulator 05 is full, the gaseous refrigerant flows along the return pipe 06 07 and liquid refrigerant 08 flow into the compressor, but because the evaporator is in the defrosting state, the liquid refrigerant 08 vaporizes under the high temperature and high pressure state, more gaseous refrigerant 07 and liquid refrigerant 08 pour into the accumulator , flooding the exhaust pipe port in the liquid receiver, when the gas-liquid two-phase refrigerant flows out, the liquid receiver will have an abnormal "grunt" noise, and this noise is intermittent and discontinuous, and the time of occurrence is not fixed , especially in the dead of night, the "grunt" noise of the reservoir will affect the normal work and rest of the user
[0004] At present, there are few studies on the noise of the reservoir, and the existing improvement measures can only isolate the sound from the outside
The most common way is to wrap the shock-absorbing cement or sound-proof cotton on the liquid reservoir shell, but since the shock-absorbing plaster is mainly used for vibration suppression, and there is no large vibration of the pipeline inside the liquid reservoir, only the gas leaks in the liquid. The sound of bubbles, and the sound insulation cotton can not be completely sealed, the noise can still leak through the intake and exhaust pipes of the liquid storage, so that the sound insulation effect is limited, and the noise of the liquid storage can not be cured; there are also manufacturers who increase the position of the liquid storage. The thickness of the foam layer to isolate the reservoir noise through the foam layer, but the reservoir noise can still be heard with the refrigerator door open

Abstract

The invention provides a refrigerator. The refrigerator comprises a storage chamber, and a refrigerating system for providing the cooling capacity for the storage chamber; the refrigerating system comprises a compressor, a condenser, a throttling device and an evaporator; a liquid storage device is arranged between an outlet of the evaporator and a gas suction opening of the compressor, and the liquid storage device comprises a liquid storage cavity with the two open ends; the evaporator and the liquid storage device communicate through a first guide pipe, and the first guide pipe is insertedinto the liquid storage cavity from a lower end opening of the liquid storage cavity; an upper end opening of the liquid storage device and the compressor communicate through a second guide pipe; theextending direction of the liquid storage cavity inclines relative to the horizontal plane; and the free end, stretching into the liquid storage cavity, of the first guide pipe is higher than the lowermost surface of the upper end opening of the liquid storage device, and the pipe wall of the second guide pipe is not higher than the lowermost surface of the upper end opening of the liquid storagedevice. At the defrosting stage, when multiple liquid refrigerants are stored in the liquid storage device, 'purr' noise caused by gas-liquid two-phase refrigerants in the liquid storage device is effectively avoided, and the sound quality experience of a product is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator. Background technique [0002] The liquid receiver is an important part of the air-cooled refrigerator. It mainly plays two roles. One is the liquid-gas separation function, which separates the liquid refrigerant from the gaseous refrigerant; the other is the liquid storage function. To meet the refrigeration needs in different environments, and increase the self-regulation ability of the refrigerator to cope with load changes. [0003] The existing liquid receiver is set between the evaporator and the compressor, such as figure 1 As shown, the gas-liquid two-phase refrigerant enters the transition pipe 02 from the capillary tube 01, flows through the evaporator 03 and enters the accumulator 05 through the conduit 04, and when the refrigerant in the accumulator 05 is full, the gaseous refrigerant flows along the return pipe 06 07 and liquid refrigera...
