Accumulator, compressor, and refrigeration cycle apparatus

Abstract

An accumulator includes: a container; a partition plate dividing an internal space of the container into a refrigerant introduction chamber and a refrigerant discharge chamber; an inlet pipe including an inlet flow channel connected to the refrigerant introduction chamber; at least one communication pipe including an outlet opening disposed in the refrigerant discharge chamber and a communication flow channel connecting the refrigerant introduction chamber with the refrigerant discharge chamber, and passing through the partition plate; at least one outlet pipe including an inlet opening disposed in the refrigerant discharge chamber and an outlet flow channel connected to the refrigerant discharge chamber; and a deflection portion blocking views from the outlet opening and the inlet opening, and deflecting a direction of flow of a refrigerant so as to prevent the refrigerant flowing from the outlet opening into the refrigerant discharge chamber from directly flowing to the inlet opening.

What is claimed is: 
     
         1 . An accumulator comprising:
 a container;   a partition plate that is disposed inside the container, and divides an internal space of the container into a refrigerant introduction chamber and a refrigerant discharge chamber;   an inlet pipe that is fixed to the container and includes an inlet flow channel connected to the refrigerant introduction chamber;   at least one communication pipe that includes an outlet opening disposed in the refrigerant discharge chamber and a communication flow channel connecting the refrigerant introduction chamber with the refrigerant discharge chamber, and passes through the partition plate;   at least one outlet pipe that includes an inlet opening disposed in the refrigerant discharge chamber and an outlet flow channel connected to the refrigerant discharge chamber, and is fixed to the container; and   a deflection portion that is disposed inside the refrigerant discharge chamber to block views from the outlet opening and the inlet opening, and deflects a direction of flow of a refrigerant so as to prevent the refrigerant flowing from the outlet opening into the refrigerant discharge chamber from directly flowing to the inlet opening.   
     
     
         2 . The accumulator according to  claim 1 , wherein the deflection portion is a baffle plate disposed in the refrigerant discharge chamber. 
     
     
         3 . The accumulator according to  claim 1 , wherein the deflection portion is a bent pipe portion disposed at an end portion of the at least one communication pipe, the end portion being disposed in the refrigerant discharge chamber. 
     
     
         4 . A compressor comprising:
 a sealed container;   a compression mechanism housed in the sealed container;   an electric motor that is housed in the sealed container and generates driving force of the compression mechanism; and   the accumulator according to  claim 1  that is placed outside the sealed container and connected to a suction side of the compression mechanism.   
     
     
         5 . A refrigeration cycle apparatus comprising:
 the compressor according to claim  4 ;   a radiator;   an expansion device;   a heat absorber; and   refrigerant piping that connects the compressor, the radiator, the expansion device, and the heat absorber to circulate a refrigerant.
