Embodiment 1

[0042] Attached below Figure 3-7 The present invention is described in detail, specifically, the structure is as follows:

[0043] In this embodiment, a three-chamber profiling suction muffler includes a first housing 11 and a second housing 12, the first housing 11 is installed above the second housing 12, and the first housing 11 and the second housing 12 The contacting side of the second housing 12 is an open structure, and slots are provided at the open ends of the two, and the front and back are inserted together through the slot structure to form a closed structure, which has good sealing performance and high structural strength.

[0044] The interior of the three-chamber profiling suction muffler is divided into a first expansion cavity 14, a second expansion cavity 15 and a resonance cavity 16, and the first expansion cavity 14 is connected in series with the second expansion cavity 15, and the second expansion cavity 15 and the resonance cavity 16 in series. The st...

Embodiment 2

[0066] Such as figure 1 and figure 2 As shown, a compressor includes a suction muffler 1, a cylinder block 2, and a motor 4. The suction muffler 1 adopts the three-chamber profiling suction muffler of the first embodiment.

[0067] The cylinder block 2 is installed on the top of the suction muffler 1, and the air outlet connecting section 115 is matched with the cylinder head 3; The two surfaces match.

[0068] The shape of the suction muffler 1 is consistent with the cylinder block 2, the cylinder head 3, and the motor 4, that is, it adopts a profiling design, which can make full use of the space and increase the volume of the muffler.

[0069] The suction muffler 1 maintains a safe distance of 1-2mm from the cylinder block 2, the cylinder head 3, and the motor 4, so as to avoid contact and collision.

[0070] Preferably, the safety distance is set to 2mm.

Abstract

The invention discloses a three-cavity profiling suction muffler and a compressor, which solves the problems of the existing muffler, such as poor muffler effect on middle and low frequency noise, insufficient muffler capacity, easy resonance, large leakage, etc., and has the advantages of Enhance the noise reduction effect on middle and low frequency noise, increase the noise reduction volume, and avoid vibration; the technical solution is: including a first casing and a second casing, and the first casing is inserted above the second casing; the second casing The upper surface of a casing has a first curved surface adapted to the cylinder seat, and the first curved surface is offset and inclined to be provided with an air outlet connection section for matching the cylinder head; the first casing and the second casing The side surfaces of the body respectively have second curved surfaces adapted to the motor; the inside of the first housing and the second housing are divided into a resonance cavity and a first expansion cavity and a second expansion cavity connected in series, wherein the first The second expansion cavity inside the second housing is connected in series with the resonance cavity.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a three-cavity profiling air suction silencer and a compressor. Background technique [0002] The suction noise of the refrigerator compressor is an important source of the noise of the whole machine, and a suction muffler is usually installed to reduce the noise. After research, the inventor found that the existing compressor suction muffler has the following deficiencies: [0003] (1) Most of the existing compressor suction mufflers are expansion mufflers, which do not have a good muffler effect on medium and low frequency noise; [0004] (2) The shape and structure of the existing compressor suction muffler is relatively regular, and the available space cannot be used to increase the volume of the muffler, resulting in insufficient noise reduction; [0005] (3) The main structure of the existing compressor suction muffler is an upper shell, a lower shell, and an inne...
