Abstract

A vapor-liquid separator includes a casing having an accommodation space, an inlet at the casing to allow a refrigerant mixture fluid to be intaken to the accommodation space therethrough, and an outlet at the side of the inlet to allow a gas phase refrigerant separated from the refrigerant mixture fluid to be discharged therethrough.

First claim

What is claimed is:

1 . A vapor-liquid separator comprising:
a casing having an accommodation space; an inlet at a side of the casing, and the inlet to allow a refrigerant mixture fluid to be provided into the accommodation space; and an outlet at the same side of the casing as the inlet, and the outlet to allow a gas phase refrigerant, separated from the refrigerant mixture fluid, to be discharged from the accommodation space.

2 . The vapor-liquid separator of claim 1 , wherein the outlet is spaced apart from the inlet on the same side of the casing, and the inlet is at an upper portion of the same side of the casing, and the outlet is at a lower portion of the same side of the casing.

3 . The vapor-liquid separator of claim 2 , further comprising:
a suction pipe that extends through the inlet to the accommodation space.

4 . The vapor-liquid separator of claim 3 , further comprising:
a first partition to protrude from a surface of the casing in a direction perpendicular to an outer surface of the casing, the first partition to face the inlet and the outlet, and the first partition is spaced apart from the side of the casing on which the inlet and the outlet are provided.

5 . The vapor-liquid separator of claim 4 , wherein the accommodation space of the casing includes a discharge flow channel and a liquid storage part, the discharge flow channel to allow the gas phase refrigerant to be discharged, and the liquid storage part to be a storage of a liquid phase refrigerant and oil separated from the refrigerant mixture fluid.

6 . The vapor-liquid separator of claim 4 , comprising a communication hole at an upper portion of the first partition, the communicating hole for connecting the discharge flow channel and the liquid storage part.

7 . The vapor-liquid separator of claim 4 , comprising an oil return hole at the first partition, wherein oil discharged through the oil return hole is to be received by a compressor, and a liquid phase refrigerant discharged through the oil return hole is to be evaporated to be collected by the compressor.

8 . The vapor-liquid separator of claim 4 , further comprising:
a second partition in the casing in a direction perpendicular to an outer surface of the casing, and the second partition is spaced apart from the side of the casing having the inlet and the outlet.

9 . The vapor-liquid separator of claim 8 , wherein the second partition includes a return hole to provide a return flow channel for a refrigerant mixture fluid to be provided to the outlet.

10 . The vapor-liquid separator of claim 9 , wherein the second partition includes a filter to filter a foreign object from the returned refrigerant mixture fluid.

11 . The vapor-liquid separator of claim 10 , wherein the filter has a first side that surrounds the return hole and a second side that protrudes toward the outlet.

12 . A vapor-liquid separator comprising:
a casing having an inlet and an outlet provided on a same side of the casing, and the casing having an accommodation space; a return flow channel at the casing to return a refrigerant mixture fluid to the outlet in a direction different from a direction in which the refrigerant mixture fluid is received at the inlet; and a suction pipe that extends through the inlet to the return flow channel.

13 . The vapor-liquid separator of claim 12 , wherein the return flow channel is provided at a different side of the casing as compared to a side in which the refrigerant mixture fluid is provided.

14 . The vapor-liquid separator of claim 13 , wherein the return flow channel is provided by a partition, and part of the return flow channel extends in a direction perpendicular to an outer circumferential surface of the casing.

15 . The vapor-liquid separator of claim 14 , wherein the partition has a return hole to provide a refrigerant mixture fluid in a direction toward the outlet, and the return hole is within a range of ⅓ to ¾ of a length of the partition.

16 . The vapor-liquid separator of claim 15 , wherein the partition includes a filter to filter a foreign object, and to allow a refrigerant mixture fluid to pass therethrough.

17 . A vapor-liquid separator comprising:
a casing having an inlet and an outlet provided on a same side of the casing, and the casing having an accommodation space, wherein a central line of the casing parallel to an outer circumferential surface of the casing is downwardly sloped toward the outlet with respect to a horizontal plane.

18 . The vapor-liquid separator of claim 17 , wherein the casing includes a first partition to separate a storage space of a liquid phase refrigerant and oil separated from a refrigerant mixture fluid from the inlet, and a discharge flow channel of a gas phase refrigerant.

19 . The vapor-liquid separator of claim 18 , wherein the first partition has a plurality of oil return holes.

20 . A vapor-liquid separator comprising:
a casing having an inlet and an outlet provided on a same side of the casing in a direction in which a central line parallel to an outer circumferential surface passes, and the casing having an accommodation space; and a partition having a return flow channel formed at another side of the casing in a direction in which the central line passes, the return flow channel to return a refrigerant mixture fluid in a direction different from a direction in which the refrigerant mixture fluid is received at the inlet.

21 . A vapor-liquid separator comprising:
a casing having an inlet and an outlet provided on a same side of the casing in a direction in which a central line parallel to an outer surface passes, and the casing having an accommodation space; a return flow channel formed at another side of the casing in a direction in which the central line passes, the return flow channel to return a refrigerant mixture fluid in a direction different from a direction in which the refrigerant mixture fluid is received from the inlet; and a discharge flow channel to allow the returned refrigerant mixture fluid to be discharged to the outlet.

22 . The vapor-liquid separator of claim 21 , wherein the return flow channel and the discharge flow channel face the inlet and the outlet, and the return flow channel and the discharge flow channel are separated by a partition in a direction perpendicular to an outer surface of the casing.

23 . A clothes treating apparatus comprising:
a cabinet; a drum rotatably provided within the cabinet, and the drum is configured to receive laundry or a dry target; a heat pump module to circulate a refrigerant by an evaporator, a vapor-liquid separator, a compressor, a condenser, and an expansion valve, and to circulate air discharged from the drum to the drum by using the evaporator and the condenser; and a casing having an inlet and an outlet on a same side of the casing facing the evaporator, and the casing having an accommodation space.

24 . The clothes treating apparatus of claim 23 , wherein the casing includes a suction pipe that extends through the inlet to the accommodation space, and that extends to a return flow channel of a refrigerant mixture fluid.

25 . The clothes treating apparatus of claim 23 , wherein the casing has a front side on which the inlet and the outlet are provided, and is positioned to be lower than a rear side of the casing.
