Embodiment approach 1
[0062] The oil separator 5 according to Embodiment 1 will be described. Such as figure 2 as well as image 3 As shown, the oil separator 5 includes a separation container 56 constituting a separation chamber 55 . The separation container 56 is formed in a substantially columnar shape in consideration of productivity. An inflow pipe 15 is attached to a side surface of the separation container 56 as a part of the refrigerant pipe 13 . The inflow pipe 15 is installed in a direction substantially perpendicular to the tangential direction of the side surface of the separation container 56 . The inflow pipe 15 connects the discharge side of the compressor 3 to the oil separator 5 (separation container 56 ).
[0063] An outflow pipe 17 is attached to the upper surface of the separation container 56 as a part of the refrigerant pipe 13 . Outflow pipe 17 connects between oil separator 5 (separation vessel 56 ) and condenser 7 . In the lower part of the separation container 56, a...
Embodiment approach 2
[0073] The oil separator 5 according to Embodiment 2 will be described. Such as Figure 7 as well as Figure 8 As shown, the oil separator 5 includes a substantially cylindrical separation container 56 constituting a separation chamber 55 . An inflow pipe 15 is attached to a side surface of the separation container 56 as a part of the refrigerant pipe 13 . The inflow pipe 15 is installed substantially along the tangential direction of the side surface of the separation container 56 .
[0074] Such as Figure 9 As shown, a liquid flow path portion 57 is provided on the inner wall surface of the separation container 56 . In the liquid channel portion 57 , a groove 57 a spirally extending toward the oil storage portion 61 is formed along the inner wall surface of the separation container 56 . The spiral groove 57a is formed such that the depth D of the groove 57a becomes gradually deeper from the upper part to the lower part. That is, the spiral groove 57a is formed to grad...
Embodiment approach 3
[0083] The oil separator 5 according to Embodiment 3 will be described.
[0084](1st case)
[0085] First, the first example will be described. Such as Figure 12 As shown, the oil separator 5 includes a separation container 56 constituting a separation chamber 55 . A turning part 59 is provided on the upper part of the separation container 56 . An inflow pipe 15 is attached to the turning portion 59 as a part of the refrigerant pipe 13 . An oil storage part 61 is provided at the lower part of the separation container 56 . An oil return pipe 19 is attached to the oil storage portion 61 .
[0086] Next, the turning portion 59 will be described. Such as Figure 13 As shown, the swivel portion 59 includes blades 63 that are rotated by the flow of refrigerant or the like. The liquid flow path portion 57 is provided on the blade wall surface 65 of the blade 63 . A groove 57 a is formed in the liquid channel portion 57 . The groove 57a is formed from the portion on the rot...
