The present invention relates to a fixing device for a accumulator for a compressor, and more particularly, to a fixing device for a accumulator for a compressor to reduce noise by reducing the vibration of the accumulator fixed to the outer surface of the compressor.

In general, a compressor is a device that pressurizes a refrigerant as part of a refrigeration cycle device to change the pressure and temperature of the refrigerant to suit a predetermined purpose, and the refrigeration cycle device includes a compressor, a condenser, an expansion means, and an evaporator. The components are connected to form a closed cycle.

Such a refrigeration cycle apparatus compresses the refrigerant gas in the low temperature and low pressure state sucked into the compressor and discharges the refrigerant gas at the high temperature and high pressure state, thereby discharging the latent heat to the liquid phase while passing through the condenser and converting it into a liquid phase. While the pressure is reduced through the evaporator, the low pressure refrigerant evaporates to absorb external heat, and the vaporized refrigerant is re-introduced into the compressor and the process is repeated.

The refrigeration cycle device is mounted on an air conditioner (aka, air conditioner) or a refrigerator to keep the room comfortable or keep food fresh by using cold and heat formed in a condenser and an evaporator.

On the other hand, when the refrigerant passing through the evaporator of the refrigerating cycle apparatus flows into the compressor, when the refrigerant in the liquid state of the microfiber flows into the compressor, an abnormal explosion noise occurs in the compressor.

In order to prevent such a phenomenon, an accumulator is provided to vaporize the liquid refrigerant before the refrigerant passing through the evaporator flows into the compressor or to prevent the inflow of impurities.

The accumulator is installed to be located on the side of the compressor, and the accumulator is connected and installed by the compressor and a connecting pipe, and is fixed by a separate fixing means to a sealed container constituting the compressor to prevent shaking, or vibration, during operation of the compressor. do.

If a closed rotary compressor which is one of the conventional compressors equipped with such an accumulator will be described as an example.

The hermetic rotary compressor compresses the refrigerant by rotating the rotor in the cylinder without centrifugal force. The refrigerant is rotated and rotated along the inner circumferential surface of the cylinder in conjunction with the rotation of the eccentric roller mounted on the lower part of the crankshaft.
