Description

Technical Field

[0001] This utility model relates to the field of compressor equipment technology, specifically a low-noise refrigerator compressor housing. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving a piston through the operation of a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.

[0003] For example, the invention patent application with publication number CN104235069A discloses a rust-proof and low-noise housing for a refrigerator compressor and its manufacturing method. The housing is treated with a dense protective layer to prevent rust, which improves the rigidity and natural frequency of the product, thereby reducing vibration and noise and improving product quality.

[0004] However, in actual use, the housing cannot quickly fix the upper and lower housings together, and usually requires the use of bolts to fix the height, which reduces the assembly efficiency and cannot well meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise refrigerator compressor housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A low-noise refrigerator compressor housing includes: an upper housing and a lower housing, wherein the upper end of the lower housing has an assembly groove for inserting the upper housing, and the upper housing has a noise reduction component; a fixing mechanism is disposed on the lower housing for quickly fixing the upper housing and the lower housing; and fixing slots are also provided around the upper housing for cooperating with the fixing mechanism.

[0008] As a preferred embodiment, the fixing mechanism includes a fixing nut seat fixed on the lower housing, a fixing handwheel threaded onto the fixing nut seat, a fixing groove provided on the lower housing, a fixing block slidably installed in the fixing groove, and the end of the fixing handwheel rotatably connected to the fixing block.

[0009] As a preferred embodiment, the depth of the fixed groove is greater than the depth of the fixed slot.

[0010] As a preferred embodiment, the fixed handwheel is provided with anti-slip texture.

[0011] As a preferred embodiment, the lower end of the lower housing is also provided with a support leg, the lower end of the support leg is provided with a foot pad, and the upper end of the foot pad is provided with a support slot.

[0012] As a preferred embodiment, the noise reduction assembly includes a noise reduction cover installed inside the upper housing, and the noise reduction cover has a plurality of noise reduction holes distributed inside.

[0013] As a preferred embodiment, the soundproof cover has a multi-layer structure, including an inner polyurethane foam layer, a middle sound-absorbing cotton layer, and an outer rock wool layer.

[0014] As a preferred embodiment, the silencing hole is a conical hole.

[0015] Compared with existing technologies, the advantages of this invention are: by inserting the upper shell into the assembly slot of the lower shell, the upper and lower shells can be quickly assembled using a fixing mechanism. This simple operation effectively improves assembly efficiency and better meets usage requirements. The invention has a reasonable structure, allowing for rapid assembly of the upper and lower shells, thus effectively improving assembly efficiency and better meeting usage needs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 A low-noise refrigerator compressor housing includes: an upper housing 2 and a lower housing 1. The upper end of the lower housing 1 is provided with an assembly groove 10 for inserting the upper housing 2. The upper housing 2 is provided with a noise reduction component. A fixing mechanism 3 is provided on the lower housing 1 for quickly fixing the upper housing and the lower housing. The upper housing 2 is also provided with fixing slots 21 around its perimeter for cooperating with the fixing mechanism 3.

[0024] The working principle of this utility model is as follows: In specific use, the upper shell 2 is first inserted into the assembly slot 10 of the lower shell 1. Then, the upper shell 2 and the lower shell 1 can be quickly assembled by the fixing mechanism 3. The operation is simple and can effectively improve the assembly efficiency, thereby better meeting the needs of use.

[0025] As a further embodiment, the fixing mechanism 3 includes a fixing nut seat 31 fixed on the lower housing 1, a fixing handwheel 32 threaded onto the fixing nut seat 31, and a fixing groove 35 provided on the lower housing 1. A fixing block 33 is slidably installed in the fixing groove 35. The end of the fixing handwheel 32 is rotatably connected to the fixing block 33. To prevent the fixing block 33 from detaching from the fixing groove 35, the depth of the fixing groove 35 is greater than the depth of the fixing slot 21. To facilitate the rotation of the fixing handwheel 32, anti-slip textures are provided on the fixing handwheel 32.

[0026] The working principle of the fixing mechanism 3 is as follows: When fixing, the upper housing 2 is inserted into the assembly slot 10 of the lower housing 1, and then the fixing handwheel 32 is rotated. The fixing handwheel 32 pushes the fixing block 33 to move, so that the fixing block 33 is inserted into the fixing slot 21, and the fixing work is completed. The operation is simple and convenient for assembly.

[0027] As a further embodiment, the lower end of the lower housing 1 is also provided with a support leg 11, the lower end of the support leg 11 is provided with a foot pad 12, and the upper end of the foot pad 12 is provided with a support slot 13. In this embodiment, the foot pad 12 is made of rubber material, which can effectively reduce the noise generated by housing vibration.

[0028] As a further embodiment, the noise reduction assembly includes a noise reduction cover 22 installed inside the upper housing 2. The noise reduction cover 22 has a plurality of noise reduction holes 23 distributed inside it. The noise reduction cover 22 has a multi-layer structure, including an inner polyurethane foam layer, a middle sound-absorbing cotton layer and an outer rock wool layer. The noise reduction holes 23 are conical holes.

[0029] By setting up a multi-layered soundproof cover 22, the sound insulation and heat preservation effects of the shell can be improved. Polyurethane foam has good heat insulation properties, which can effectively prevent heat loss and improve the energy utilization rate of the compressor. Sound-absorbing cotton has good sound absorption performance, which can effectively reduce the noise generated by the compressor. Rock wool can further improve the heat preservation and sound insulation performance of the soundproof cover 22. The conical sound-absorbing holes 23 facilitate the entry of noise and make it easy for the sound-absorbing cotton to absorb it.
