Problems solved by technology

[0006] However, due to the pressure difference caused by the periodic volume change of the compression mechanism 30, the periodic static pressure difference in the accumulator container 50 is caused, so that the lubricating oil accumulated at the bottom of the accumulator container 50 is periodically inflowed into the connection. tube 40, this periodic flow not only disturbs the flow of refrigerant gas, but also induces vibration and noise

Embodiment Construction

[0014] Such as figure 2 As shown, the airtight container 10 in the hermetic compressor is provided with a transmission mechanism 20 and a compression mechanism 30, and the accumulator A is arranged on the side of the airtight container 10 and is connected with the airtight container 10 through a curved connecting pipe 40 to be connected with the airtight container 10. The compression mechanism 30 communicates.

[0015] The accumulator A is composed of an accumulator container 50 , a cooling tube 60 , and a screen 70 . The liquid storage container 50 is cylindrical with a certain internal space, the connecting pipe 40 extends into it from the bottom, and the cooling pipe 60 is connected to the upper end of the liquid storage container 50; the screen 70 is installed on the connecting pipe 40 through the screen frame 71 The liquid reservoir container 50 above the upper end is used for filtering oil and foreign matters mixed in the refrigerant. The connecting pipe 40 is made up...

Abstract

An oil recovering unit of liquid tank for sealed compressor is composed of liquid accumulating container communicated to evaporator via refrigerating tube, connecting tube connected between compressing mechanism and liquid accumulating container, and fine oil tube connected between bottom of said container and elbow of connecting tube. It can prevent the interference between oil stream and refrigerating gas strem for reducing vibration and noise, and improve compression performance.

Description

1. Technical field [0001] The invention relates to an oil recovery device of a liquid accumulator of a hermetic compressor. 2. Background technology [0002] A compressor is a machine that compresses refrigerant gas. According to the way it compresses gas, it can be divided into various types such as rotary compressors, reciprocating compressors, and scroll compressors. These compressors are installed in the refrigeration cycle of refrigerators or air conditioners and form a closed system. The hermetic compressor is mainly composed of a hermetic container, a transmission mechanism and a compression mechanism. The airtight container has a certain internal space; the transmission mechanism is installed in the internal space of the airtight container to generate the driving force to drive the compression mechanism; the compression mechanism is driven by the transmission mechanism to compress the refrigerant gas, and the above compressor can be divided into There are two types...
