Specific embodiment
It is as shown in Figs. 1-3:
A kind of muffler of refrigerator, including muffler shell 1, sealing side plate 2 and hush pipe 3, the muffler shell 1
Two groups of first partition slots 102 being oppositely arranged, the first partition slot of opposite two are offered on internal opposite two sidewalls
The partition 301 that the muffler shell 1 is divided into three seal cavities 6 is connected between 102, the hush pipe 3 runs through two
A partition is mounted in the muffler shell 1, and multiple spherical inner chambers, the hush pipe 3 are designed as in the hush pipe 3
Top noise reduction outlet mouth of pipe 302 is installed, the bottom of the hush pipe 3 is equipped with noise reduction air inlet mouth of pipe 303, with the noise reduction
The top of the opposite muffler shell 1 of outlet mouth of pipe 302 offers muffler escape pipe 101, the muffler escape pipe
101 are connected to the seal cavity 6 with the noise reduction outlet mouth of pipe 302, it is opposite with the noise reduction air inlet mouth of pipe 303 described in disappear
The end of sound device air inlet pipe 201 offers the clamping groove 204 for being connected to the noise reduction air inlet mouth of pipe 303, the muffler into
Acoustic damping mesh 203 is installed in 201 inner section of tracheae, the first inserting groove 401 on the sealing side plate 2 by with the muffler
The second inserting groove 402 on shell 1 is mating, and the hush pipe 3 is sealed in the muffler shell 1.
In the present embodiment, the outer side edges of the partition 301 are set to cambered surface, convenient for cooperating the second partition slot 202
It is installed with the first partition slot 102.The partition 301 is contacted with the second partition slot 202 and the cooperation of first partition slot 102
Flexible sealing strip, such as the sealing strip of PVC material are provided on face, for guaranteeing partition and the 1 top shape of muffler shell
At seal chamber.By being designed as arc line shaped transition between multiple spherical inner chambers of the muffler air inlet pipe 201, so that air-flow has
Effectiveness is offset, convenient for buffering the pulse gas flowing due to the intermittent air-breathing of compressor and exhaust generation.The muffler shell
It is arranged on the side wall of body 1 there are two the isobaric hole 5 for keeping 1 air pressure inside of the muffler shell balance, prevents in hush pipe 3
The variation of refrigerant temperature, where causing in muffler shell body, gas pressure intensity becomes smaller, and reduces its leakproofness.First inserting groove
401 and second inserting groove 402 cooperation depth and the second partition slot 202 cooperation depth it is identical, guarantee integral installation
Sealing performance.
Operational process:
Refrigerant (refrigerant) is by the entrance of muffler air inlet pipe 201 hush pipe 3, the reducer pipe into hush pipe 3,
Then the seal cavity 6 formed by muffler shell in partition is entered by noise reduction outlet mouth of pipe 302, gone out subsequently into muffler
Tracheae 101, eventually enters into cylinder.During top, compressor for refrigeration gettering efficiency is not influenced, and reduces refrigerator pressure
The especially middle low frequency noise of the noise of contracting machine.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are practical new to this
The various changes and improvements that the technical solution of type is made should all fall into the protection scope that the utility model claims book determines
It is interior.
