[0002] The noise generated during the operation of the compressor is a major source of noise in the heat pump system, and the noise generated during the operation of the compressor mainly comes from vibration noise and air flow noise. During the operation of the compressor, its internal components will vibrate, not only generating relatively large noise by themselves, but also driving the rigid pipelines connected to it to vibrate synchronously, further increasing the noise. When the compressor compresses the refrigerant, it will also generate certain noise due to the impact and compression of the air flow. The superposition of various factors results in generally large noise during the operation of the compressor.

[0003] Currently, generally, the method of wrapping sound insulation materials outside the compressor is adopted to reduce the noise of the compressor. However, the sound insulation materials are generally wrapped outside the compressor after the heat pump system is assembled. At this time, it is necessary to plan according to the pipeline routing connected to the compressor, and the operation is relatively complex and the efficiency is also low. Utility Model Content

These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0030] To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0032] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0033] The noise generated during the operation of the compressor is a major source of noise in the heat pump system, and the noise generated during the operation of the compressor mainly comes from vibration noise and air flow noise. During the operation of the compressor, its internal components will vibrate, not only generating relatively large noise by themselves, but also driving the rigid pipelines connected to it to vibrate synchronously, further increasing the noise. The noise generated by this vibration is generally a low-frequency vibration sound or a buzzing sound, which can usually be heard at a relatively long distance. At the same time, when the compressor compresses the refrigerant, it will also generate certain noise due to the impact and compression of the air flow. This noise usually manifests as a sharp high-frequency sound or a cracking sound, which is usually heard when approaching the compressor. Of course, there is also noise caused by other factors such as friction. The superposition of these noises makes the operation of the compressor generally have relatively large noise.

[0034] Currently, generally, the method of wrapping sound insulation materials outside the compressor is adopted to reduce the noise of the compressor. However, the sound insulation materials are generally wrapped outside the compressor after the heat pump system is assembled. At this time, it is necessary to plan the wrapping method and position of the sound absorption materials according to the routing of the suction and exhaust pipelines connected to the compressor, and the operation is relatively complex and the efficiency is also low.

[0035] In order to avoid the above problems, the present application adds a sound insulation chamber outside the compressor. The sound insulation chamber is directly covered outside the compressor, and the sound insulation chamber does not come into direct contact with the compressor, but is connected to the shell of the heat pump system. On the one hand, it can effectively reduce the compressor noise, and on the other hand, the installation is fast and convenient, which can greatly reduce the operation difficulty of assembling the heat pump system and improve the assembly efficiency.

[0036] The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems through specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the drawings.

[0037] Figure 1 Is a three-dimensional view of the sound insulation chamber provided by the embodiment of the present application; Figure 2 Is Figure 1 The schematic cross-sectional structure of the sound insulation chamber in

[0038] Please refer to Figure 1 And Figure 2As shown in the figure, this embodiment provides a compressor sound insulation chamber, which includes a chamber body 100 and an elastic member 200. A noise reduction chamber 110 and a vacuum layer 120 are provided inside the chamber body 100.

[0039] Among them, the vacuum layer 120 is arranged in a ring outside the noise reduction chamber 110. The noise reduction chamber 110 has an open end. During use, the compressor 300 can be placed into the noise reduction chamber 110 through this open end. At the same time, at least one connection hole 130 is provided on the chamber body 100. The connection hole 130 penetrates through the chamber body 100 and communicates with the noise reduction chamber 110. The connection hole 130 is used for pipelines such as the suction and exhaust pipelines of the compressor 300 to pass through. The elastic member 200 is installed in the connection hole 130 to separate the suction and exhaust pipelines from the hole wall of the connection hole 130 through the elastic member 200.

[0040] Of course, the number of connection holes 130 can be adjusted according to installation requirements. For example, one connection hole 130 can be provided corresponding to each pipeline, or multiple pipelines can share one connection hole 130. Of course, it is advisable to have one connection hole 130 corresponding to one pipeline and the inner diameter of the connection hole 130 being equivalent to the outer diameter of the pipeline to assist in reducing the overflow of noise and improving the noise reduction effect.

[0041] When installing the compressor 300, the compressor 300 is fixed inside the housing 400 of the heat pump system for installing various components. The chamber body 100 is covered outside the compressor 300 through the open end, and the suction and exhaust pipelines connected to the compressor 300 are passed through the connection hole 130 and extended to the outside of the chamber body 100. Then, the chamber body 100 is fixed inside the housing 400 of the heat pump system.

[0042] The entire installation process is extremely simple. The chamber body 100 can be pre-fabricated in the factory and simply fixed on the housing 400 of the heat pump system during use, which can greatly reduce the operation burden of the staff and improve the assembly efficiency of the heat pump system.

[0043] At the same time, during the use of the heat pump system, the noise generated by the compressor 300 will be blocked by the chamber body 100. The existence of the vacuum layer 120 can effectively control the outward transmission of noise. In addition, the elastic member 200 can also separate the suction and exhaust pipelines from the hole wall of the connection hole 130, reduce the influence of the vibration of the suction and exhaust pipelines on the chamber body 100, further improve the use effect of the sound insulation chamber, and assist in reducing noise.

[0044] Of course, the sound insulation chamber will not have a great impact on the structures of the compressor 300 and the heat pump system and can be directly applied to existing heat pump systems with wide applicability.

[0045] In a possible implementation, the bin body 100 can be composed of an outer shell and an inner shell. After the outer shell and the inner shell are assembled, a vacuum layer 120 is formed between the outer shell and the inner shell, and the noise reduction cavity 110 is on the side of the inner shell away from the outer shell. Of course, a suction port can also be opened on the outer shell or the inner shell. After assembly, vacuum pumping is performed through the suction port to form the vacuum layer 120.

[0046] In a possible implementation, the elastic member can be an elastic gasket directly attached to the surface of the connection hole.

[0047] Figure 3 For Figure 1 the structural schematic diagram of the elastic member in

[0048] In a possible implementation, please refer to Figure 3 As shown, the elastic member 200 can be an elastic sleeve. A through hole for the suction and exhaust pipeline to pass through is formed inside the elastic sleeve. Of course, the elastic sleeve can be fixed in the connection hole 130 by means of clamping or gluing, etc. When the suction and exhaust pipeline passes through the connection hole 130, it is directly in contact with the elastic sleeve, and the vibration transmitted by the suction and exhaust pipeline can be reduced to a certain extent through the elastic sleeve, thereby reducing the influence of pipeline vibration on the bin body 100, and also assisting in reducing noise.

[0049] On the basis of the above embodiment, in this embodiment, the elastic sleeve includes a cylinder body 210 and connection platforms 220 located at both ends of the cylinder body 210. The connection platforms 220 are located outside the connection hole 130 and are in contact with the inner side wall or the outer side wall of the bin body 100. Of course, the cylinder body 210 has the same length as the connection hole 130 and is completely located inside the connection hole 130. In this way of setting, during assembly, the elastic member 200 can be directly clamped on the bin body 100 through the connection platforms 220, thereby restricting the relative position of the elastic member 200 and the connection hole 130, so that the elastic member 200 can be directly fixed in the connection hole 130 without the need for external tools or operations such as gluing or heat melting. This makes the installation of the elastic member 200 simpler, and at the same time, it is more convenient to replace when the elastic member 200 is worn out after long-term use.

[0050] Figure 4 For Figure 3 the structural schematic diagram of the connecting body in

[0051] In a possible implementation, please refer to Figure 4 As shown, the cylinder body 210 is composed of at least two arc-shaped connecting bodies 211 spliced together, and connection platforms 220 are arranged at both ends of each connecting body 211.

[0052] Exemplarily, the cylinder body 210 is composed of two connecting bodies 211 joined together. At this time, the cross-section of each connecting body 211 is a semi-circle, and a circular cylinder body 210 can be formed after the two connecting bodies 211 are joined together. When assembling the elastomer with the bin body 100, the connecting bodies 211 can be successively inserted into the connecting holes 130 for assembly. Since the elastomer has the ability to recover from deformation, after it is engaged with the connecting holes 130 in place, the connecting bodies 211 will automatically return to their original shape, making it easier to install the elastic sleeve.

[0053] Among them, the cylinder body 210 and the sleeve can be processed separately and then fixed together by means of adhesives or hot melting. The cylinder body 210 and the sleeve can also be integrally formed to improve the connection stability.

[0054] Of course, the elastic sleeve can be made of common materials such as rubber or sponge, as long as it can isolate the suction and exhaust pipeline from the connecting holes 130 and reduce the transmission of vibration.

[0055] Figure 5 It is a schematic structural diagram of the assembled state of the sound insulation bin and the compressor unit; Figure 6 It is Figure 5 The schematic structural diagram of the sound insulation bin and the compressor in a separated state in

[0056] Based on the above embodiments, please refer to Figure 5 and Figure 6 As shown, this embodiment provides a heat pump system, which includes a housing 400, a compressor 300, a condenser, an expansion valve, a four-way valve and other components, and also includes the sound insulation bin mentioned in the above embodiments. Of course, components such as the compressor 300, the condenser, the expansion valve, the four-way valve, and the sound insulation bin are all installed in the housing 400.

[0057] Among them, components such as the compressor 300, the four-way valve, the condenser, the evaporator, and the expansion valve are connected by pipelines, so that the refrigerant can flow along the pipelines among the components for circulation.

[0058] During use, the compressor 300 compresses the refrigerant into a high-temperature and high-pressure gas. Subsequently, the refrigerant enters the condenser through the four-way valve to exchange heat with water to heat the water. After heat exchange, the refrigerant becomes a medium-temperature and high-pressure liquid, becomes a low-temperature and low-pressure gas-liquid mixture after passing through the expansion valve, and enters the evaporator to exchange heat with the gas. After the refrigerant absorbs heat, it becomes a gas and enters the compressor 300 again for circulation.

[0059] The sound insulation bin covers the outside of the compressor 300 to reduce the noise generated during the operation of the heat pump system.

[0060] Specifically, the compressor 300 is placed into the noise reduction chamber 110 through the open end of the noise reduction chamber 110. At the same time, the suction and exhaust pipe lines connected to the compressor 300 all extend outside the housing 100 through the connection holes 130 to be connected to other components, and the housing 100 is fixed inside the housing 400.

[0061] In a possible implementation manner, the lower end of the compressor 300 is provided with feet for connecting to the housing 400. The shape of the housing 100 is adapted to the shape of the compressor 300, and a through groove 140 adapted to the position of the feet is provided at the lower end of the housing 100. That is, the housing 100 is designed to be shaped after the outer shape of the compressor 300, so that the gap between the noise reduction chamber 110 and the compressor 300 is small. This enables the housing 100 to block the transmission of noise, and at the same time, it will not directly contact the compressor 300, avoiding the synchronous vibration of the housing 100 and the compressor 300, and effectively reducing the volume of the sound insulation chamber, avoiding its impact on the overall volume of the heat pump system. This enables the sound insulation chamber to be directly applied to the existing heat pump system without changing the structure of the heat pump system, having strong adaptability.

[0062] Among them, in order to facilitate fixing the housing 100 inside the housing 400 and prevent it from shaking during the use of the heat pump system, an installation part 150 can be provided at the lower end of the housing 100, and the housing 100 and the housing 400 can be detachably connected through the installation part 150.

[0063] Exemplarily, the installation part 150 can be connected to the housing 400 by a snap connection method.

[0064] Exemplarily, at least one installation hole 151 is provided on the installation part 150. Correspondingly, a threaded post 600 is provided on the housing 400. The outer diameter of the threaded post 600 is adapted to the inner diameter of the installation hole 151, and the two are directly inserted. During installation, the housing 100 is sleeved outside the compressor 300, and the threaded post 600 is inserted into the installation hole 151. Of course, the end of the threaded post 600 extends outside the installation hole 151, and then the threaded post 600 and the installation hole 151 are locked by a nut 500.

[0065] In a possible implementation manner, in order to reduce the transmission of vibration, an elastic gasket 160 can be added. The elastic gasket 160 is sleeved on the threaded post 600, and the elastic gasket 160 is located on the side of the installation part 150 away from the nut 500, that is, the elastic gasket 160 is padded between the installation part 150 and the housing 400 to effectively reduce the transmission of vibration.

[0066] Exemplarily, the bin body 100 and the housing 400 can also be connected by a magic tape. At this time, holes can be drilled at corresponding positions of the housing 400 or the suede surface of the magic tape can be adhesively fixed, and the hook surface of the magic tape can be fixed at the corresponding position of the bin body 100.

[0067] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application.
