Problems solved by technology
[0003] The main body of the existing suction muffler adopts a single-layer structure design, and the structural design has the following problems: (1) The muffler has a mediocre noise reduction effect. To enhance the noise reduction effect, the volume of the muffler must be increased or the wall of the muffler must be increased. thicker, which will lead to changes in the overall structure of the compressor, waste of materials and increase in cost; (2) The muffler is a single-layer structure, which has poor heat insulation effect. Because the motor compressor is running, the heat of the motor core is easy Heat the muffler to increase the suction temperature of the compressor and reduce the suction efficiency

Embodiment Construction
[0014] refer to Figure 1 ~ Figure 3 , the present invention provides a double-layer direct suction muffler for refrigeration compressors, comprising a main body 1 provided with a muffler chamber 11 and an upper cover 2 buckled with the main body 1, and the upper cover 2 is provided with a pipe extending into the muffler chamber 11 Conduit 21 , the main body 1 is provided with an air inlet 15 below the conduit 21 , the main body 1 includes an inner layer 12 and an outer layer 13 , the inner layer 12 and the outer layer 13 are separated from each other and form a gas barrier 14 .
[0015] The refrigeration compressor uses a double-layer direct suction muffler during work. The working medium enters the muffler chamber 11 from the air inlet 15, and then enters the cylinder 6 of the compressor along the conduit 21. The setting of the muffler chamber 11 reduces the pressure of the compressor. The noise generated by the impact of the working medium movement during the inhalation pro...

The invention discloses a double-layer direct inhaling silencer for a refrigeration compressor. The double-layer direct inhaling silencer for the refrigeration compressor is used in the field of compressors. The double-layer direct inhaling silencer for the refrigeration compressor comprises a body with a sound deadening cavity and an upper cover fastened with the body. The upper cover is provided with a conduit stretching into the sound deadening cavity, an air inlet is formed in the body below the conduit, the body comprises an inner layer and an outer layer, and the inner layer and the outer layer are separated from each other to form a gas separating layer. The body of the double-layer direct inhaling silencer for the refrigeration compressor adopts a double-layer structure, and the structural arrangement of the inner layer, the outer layer and the gas separating layer enables the silencer to be capable of providing a better sound deadening effect with a smaller size. Meanwhile, the double-layer direct inhaling silencer for the refrigeration compressor saves materials, and reduces cost, in addition, the heat insulation effect of the silencer is improved, and therefore inhaling efficiency is improved.
Description
technical field [0001] The invention is used in the field of compressors, in particular to a direct suction muffler for refrigeration compressors. Background technique [0002] Suction mufflers are used in hermetic refrigeration compressors, and are generally made of plastic materials with better thermal insulation performance. On the one hand, it is to reduce noise, and on the other hand, it is to reduce the heating effect of the compressor heat on the refrigerant and improve compression. The suction efficiency of the machine. [0003] The main body of the existing suction muffler adopts a single-layer structure design. The structural design has the following problems: (1) The muffler has a general noise reduction effect. To enhance the noise reduction effect, the volume of the muffler must be increased or the wall of the muffler must be increased. thicker, which will lead to changes in the overall structure of the compressor, waste of materials and increase in cost; (2) T...
