Description

Noise reduction accumulator of refrigerator {ACCUMULATOR OF NOISE REDUCTION TYPE FOR REFRIGERATOR}

The present invention relates to a noise reduction accumulator of a refrigerator, and more particularly, to a noise reduction accumulator of a refrigerator capable of greatly suppressing the generation of noise due to the refrigerant fractionation of the accumulator by the post-evaporation action of the evaporator while the compressor is stopped. will be.

In general, a refrigerator includes a compressor for compressing a refrigerant at a high temperature and high pressure, a condenser for dissipating the refrigerant sent from the compressor and converting the refrigerant into a liquid refrigerant at low temperature and high pressure, and a low temperature high pressure liquid as the refrigerant passes through the condenser. It consists of a capillary tube to be converted into a refrigerant and an evaporator for converting the refrigerant sent to a low temperature low pressure state through the capillary tube to the gas state by heat exchange with the air in the refrigerator.

At this time, a recovery tube is connected between the evaporator and the compressor, so that the refrigerant converted into the gas state in the evaporator is recovered to the compressor through the recovery tube and then compressed to high temperature and high pressure.

However, the refrigerant recovered by the compressor includes a liquid refrigerant that could not be converted into a gaseous state. When the liquid refrigerant is recovered by the compressor, the compression efficiency is lowered, and thus, the cold air efficiency is lowered.

Therefore, an accumulator is provided between the evaporator and the compressor to separate the refrigerant in the gas-liquid state.

Hereinafter, an accumulator according to the prior art will be described with reference to FIGS. 1 and 2.

As shown, the accumulator 30 according to the prior art, the expansion pipe 31 having a space extended into the interior, the number of times connecting the expansion pipe 31 to the evaporator 10 and the compressor 20, respectively It consists of the tube 40.

First, the recovery tube 40 is composed of an inlet side recovery tube 41 passing from the lower portion of the expansion tube 31 to the upper portion and a discharge side recovery tube 42 formed on the upper portion of the expansion tube 31. .

In addition, the inlet side return pipe 41 is connected to the evaporator 10, and the outlet side return pipe 42 is connected to the compressor 20.

In addition, an oil recovery port 43 for recovering oil contained in the refrigerant is formed in the inflow-side recovery pipe 41.

In addition, during the operation of the compressor, the liquid refrigerant that has not been vaporized in the evaporator 10 is partially filled in the expansion pipe 31, so that the liquid refrigerant remains.

However, the accumulator 30 performs the refrigerant fractionation for a predetermined time due to the post-evaporation action of the evaporator even when the compressor stops. Therefore, there is a problem in that the liquid refrigerant rises from the inlet side return pipe, and a sound is generated in the process of discharging some gaseous refrigerant through the oil recovery port 43.

Further, after the evaporator stops the evaporator, the liquid refrigerant filled in the accumulator not only generated noise in the process of being recovered through the oil recovery port 43 of small diameter, but also the recovery time through the oil recovery port. There was a problem with this lengthening.

The present invention has been made to solve the above problems, an object of the present invention can not only greatly suppress the generation of noise due to the refrigerant fractionation of the accumulator by the post-evaporation action of the evaporator in the state in which the compressor is stopped.
