Embodiment Construction

[0051] The following is attached Figure 1-17 The embodiment of the present invention is described further, but does not limit the present invention.

[0052] Such as Figure 3-4 , 5-14, the exhaust muffler device 8 of the present invention is arranged outside the cylinder block 14, and the upper chamber 9 and the lower chamber 10 are formed by stamping two pieces of metal materials, and the upper chamber 9 and the lower chamber 10 are fastened together. The metal cavity is formed by welding, and the metal cavity is in the shape of a cuboid, or other conventional shapes, such as ellipsoid, circle, cube, etc. The most important feature is that a non-metallic material casing 12 is installed outside the metal cavity. This casing 12 can be made separately (such as injection molding), or it can be co-cast with the metal cavity by injection molding. Electroplating and other chemical processes cover the outer surface of the metal cavity with non-metallic materials. The non-metalli...

Abstract

The invention relates to a separate heat-insulating exhaust silencing device and a refrigerant compressor adopted thereby. The device comprises a metal cavity, and a gas inlet pipe mounting hole and a gas exhaust pipe mounting hole which are communicated with an inner chamber respectively, and is characterized in that: a non-metal shell is also arranged outside the metal cavity; and the exhaust silencing device is arranged outside a cylinder pedestal and is separated from the cylinder pedestal. The shell of a non-metal material is additionally arranged outside the metal cavity of the exhaust silencing device, the probability of contact of exhausted gas and internal gas of the compressor and heat transferred to the outer layer by the metal cavity of the exhaust silencing device are reduceddue to excellent heat insulation effect of the non-metal material, so that the gas in the compressor has lower temperature, and the efficiency of the compressor is increased. Meanwhile, the internal metal cavity is formed by stamping, so that the cost of materials and weight of the device can be greatly reduced, a manufacturing process is simplified, and more space is remained for the periphery of the cylinder pedestal.

Description

technical field [0001] The invention belongs to the field of manufacturing fully enclosed reciprocating piston refrigeration compressors, and in particular relates to a separate exhaust muffler device for refrigeration compressors and a refrigeration compressor using the device. Background technique [0002] The technological progress of refrigeration products such as refrigerators has driven the rapid development of the refrigeration compressor industry, and as human beings have higher and higher requirements for environmental protection and energy conservation, various refrigerator manufacturers have accelerated the development of fluorine-free energy-saving refrigerators, which has forced refrigerators to compress The refrigerator industry develops new products following the development of the refrigerator industry. The structures of existing refrigerator compressors are all reciprocating piston structures. The structure of a typical refrigerator refrigeration compressor...
