Description

[Detailed description of the invention] This invention relates to an improved configuration of an accumulator for refrigeration equipment.
In particular, noise caused by gaseous refrigerant bubbles is prevented.

Conventionally, an accumulator in this type of refrigeration equipment such as a refrigerator separates refrigerant into gas and liquid and returns the gaseous refrigerant to a refrigerant compressor or the like, but liquid refrigerant is always stored.

Therefore, when the gaseous refrigerant evaporated in the evaporator flows into this accumulator, it passes through the liquid refrigerant as bubbles and flows out from the discharge port, but immediately after the liquid refrigerant passes, the bubbles burst, and at this time The popping sound was making noise.

Therefore, in a quiet installation place, it would be unpleasant to the ears, which was not desirable.

This proposal was developed in view of these points, and the figure will be explained below.

1 is an outlet end 4 of a refrigerant evaporator 3 placed in a suitable location such as a cooling box 2.
The main body of the accumulator is connected to the main body of the accumulator, and the central part is formed into a hollow cylindrical shape with a larger diameter than the inlet 5 and the outlet 6 formed at both ends, and the inlet 5 is at the bottom and the outlet 6 is at the top. It is arranged slanted as per the position.

The discharge port 6 communicates with a refrigerant compressor (not shown) or the like via a hollow pipe 7.

Furthermore, inside the accumulator main body 1, a cotton-like body 8 made of a material that does not cause a chemical reaction with refrigerant and refrigerating machine oil, such as metal cotton formed into a multi-fiber coarse cotton, is placed over almost the entire area, or at least over the entire area. It is inserted and filled in a biased manner toward the inlet 5 side.

Reference numeral 9 and 10 denote sleeves necessary for forming welded parts 11 and 12 when the outlet end 4 and the hollow tube body 7 made of aluminum are connected by argon welding to the main body 1 made of aluminum; And if the offshore tube body 7 is made of copper, it can be omitted.

P indicates a bubble of the gaseous refrigerant, and L indicates the liquid refrigerant level in the main body 1.

Since the present invention is constructed as described above, the flocculent material is immersed in the liquid refrigerant stored in the lower part of the accumulator main body, and even if the gaseous refrigerant forms bubbles and enters from the inlet, the flocculent material In addition to preventing air bubbles from breaking down into small pieces in the body and causing so-called bursting sounds to eliminate noise, it also promotes the vaporization of liquid refrigerant and prevents the liquid from returning to the refrigerant compressor. It can also be downsized.

Claims (1)

[Claims for Utility Model Registration] 19. A main body having a diameter larger in the center than the inflow port and the discharge port formed at both ends, and arranged so as to be inclined so that the inflow port is located at the bottom and the discharge port is located at the top. At the same time, a refrigerant-resistant and refrigerating machine oil-resistant flocculent body was inserted and filled into the main body so that the lower part was immersed in the liquid refrigerant collected at the lower part of the main body, and the upper part protruded from the liquid level of the flowing refrigerant. An accumulator for refrigeration equipment that is characterized by: 2. The accumulator for a refrigerator according to claim 1, wherein the cotton-like material is made of metal cotton and is filled toward the inlet side of the main body.
