[0002] Both the compressor and the four-way valve of the heat pump system are installed in the installation space inside the housing. At the same time, the compressor needs to be connected to the four-way valve through a pipeline so that the refrigerant can leave or return to the compressor through the pipeline.

[0003] Currently, the pipeline connecting the compressor and the four-way valve is basically a rigid copper pipe. During the operation of the compressor, vibration is inevitably generated, and the vibration will be transmitted to the connected four-way valve through the rigid copper pipe, which not only easily causes damage to the connection points of the pipeline and various components, but also increases the noise during the operation of the heat pump system. In addition, it is difficult to change the shape of the rigid copper pipe after it is formed, which makes the position of the four-way valve have to be designed in advance and it is difficult to adjust the installation position of the four-way valve according to the actual installation situation, easily resulting in waste of the installation space inside the housing.

These accompanying drawings and the 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 objectives, technical solutions, and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0031] In the description and claims of this utility model and the above-mentioned accompanying drawings, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily have to be 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 this utility model described here, for example, can be implemented in an order other than those illustrated or described here.

[0032] In the embodiments of this 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 this 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] Currently, the pipeline connecting the compressor and the four-way valve in the heat pump system is basically a rigid copper pipe. This makes it necessary to pre-design the position of the four-way valve during the assembly of the heat pump system, resulting in an increase in the volume of the housing, and thus an increase in the installation space required for the heat pump system. At the same time, the copper pipe transmits vibration, which is also likely to cause loosening at the connection points with the compressor and the four-way valve.

[0034] In addition, during the operation of the compressor, vibration is inevitably generated. The vibration is transmitted to the connected four-way valve through the rigid copper pipe, which not only easily damages the connection points of the pipeline with each component, but also increases the noise during the operation of the heat pump system.

[0035] To avoid the above problems, the embodiments of this application provide a heat pump system. On the one hand, the rigid copper pipe between the four-way valve and the compressor is changed to a pipeline to avoid vibration transmission between the compressor and the four-way valve, reducing the operating noise of the heat pump system. On the other hand, a separate connection component is added to cooperate with the flexible pipeline to fix the four-way valve, and the installation position of the four-way valve can be changed according to the situation, effectively saving the installation space.

[0036] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] See also Figure 1 As shown, this embodiment provides a heat pump system, including components such as a compressor 200, a four-way valve 300, a throttle valve 400, an evaporator 700, and a heat exchanger. The compressor 200, the four-way valve 300, the throttle valve 400, the evaporator 700, and the heat exchanger are connected by pipelines to allow the refrigerant to circulate between the components. The heat pump system of this embodiment also includes a connecting assembly and a flexible pipeline 600.

[0038] Of course, the heat pump system also includes a shell 100, and components such as a compressor 200, a four-way valve 300, a flexible pipeline 600 and an evaporator 700 are all installed in the shell 100, wherein the flexible pipeline 600 is used to connect the air intake and exhaust ports of the compressor 200 with the four-way valve 300, and the connecting assembly is used to fix the four-way valve 300 at a suitable position of the shell 100.

[0039] Specifically, the flexible pipe 600 has a strong deformability. When the flexible pipe 600 is used to connect the compressor 200 and the four-way valve 300, the fixed position of the four-way valve 300 inside the housing 100 can be changed arbitrarily, that is, after installing the components in the housing 100, the remaining space inside the housing 100 can be checked, and a position convenient for installing the four-way valve 300 can be found inside the housing 100, and then the four-way valve 300 can be fixed on the housing 100 through the connecting assembly. In this way, the installation position of the four-way valve 300 is more flexible, and can be adjusted in real time according to the installation situation, which can effectively save installation space and reduce the difficulty of assembly. At the same time, after replacing the traditional rigid copper pipe with the flexible pipe 600, the transmission of vibration can be greatly reduced, the operating noise of the heat pump system can be effectively reduced, and the user experience can be improved.

[0040] In some possible implementations, the throttle valve 400 may be connected to other components via a flexible pipe 600 , and the throttle valve 400 may be fixed at a suitable position in the housing 100 via a connecting assembly.

[0041] In some possible embodiments, the flexible pipeline 600 is a metal bellows, which is lightweight, resistant to high and low temperatures, and has good flexibility. When in use, it can absorb vibration energy, effectively assist in reducing the operating noise of the heat pump system, and can also adapt to larger displacements. The direction can be adjusted according to the arrangement of the components in the shell 100, so that the fixed position of the four-way valve 300 in the shell 100 is adjustable.

[0042] Exemplarily, the flexible pipeline 600 is a stainless steel corrugated pipe.

[0043] Exemplarily, the flexible pipeline 600 is a carbon steel corrugated pipe.

[0044] Among them, the four-way valve 300 generally includes a valve body 310, four interfaces 320 opened on the valve body 310, and a valve core located inside the valve body 310. The communication state of the four interfaces 320 can be changed by moving the valve core, so as to change the flow path of the fluid flowing through the four-way valve 300.

[0045] In some possible implementation manners, in order to effectively fix the four-way valve 300, the connection assembly includes two connecting members 810. Both of the two connecting members 810 can be engaged with the valve body 310 to fix the four-way valve 300 on the housing 100.

[0046] Among them, when the four-way valve 300 is fixed on the housing 100 through the connecting member 810, at least one of the four interfaces is located between the two connecting members 810. Specifically, the interface 320 protrudes outside the valve body 310 and has strong rigidity. As long as one interface 320 is located between the two connecting members 810, the valve body 310 can be effectively prevented from disengaging from the connecting member 810. And as long as both of the two connecting members 810 are close to the interface 320, the valve body 310 can also be prevented from displacing relative to the connecting member 810, improving the connection effect between the connecting member 810 and the valve body 310.

[0047] In some possible implementation manners, please refer to Figure 2 and Figure 3 shown, please refer to Figure 4 shown. The connecting member 810 is an arc-shaped clamp. The arc-shaped clamp can be directly connected to the housing 100 through screws, and of course, it can also be fixed on the housing 100 by welding, bonding and other methods. Among them, the inner diameter of the arc-shaped clamp is adapted to the outer diameter of the valve body 310, and at least one through hole is opened at each end of the arc-shaped clamp. The through hole can be a threaded hole or a straight hole. When fixing the valve body 310, first clamp the arc-shaped clamp on the outside of the valve body 310, and then fix the arc-shaped clamp on the housing 100 through the cooperation of the screw and the through hole.

[0048] In some possible implementation manners, please refer to Figure 5 shown. The connecting member 810 can be a positioning ring. A connecting portion is provided on the positioning ring. The connecting portion can be fixed on the housing 100 through screws, and of course, it can also be fixed by welding, bonding and other methods. The inner diameter of the positioning ring is adapted to the outer diameter of the valve body 310. When installing the four-way valve 300, put a positioning ring on each end of the four-way valve 300 so that the positioning ring is in close contact with the interface, and then fix the connecting portion on the housing 100.

[0049] In some possible embodiments, please refer to Figure 6 and Figure 7 As shown, the connecting component further includes a positioning seat 830. The positioning seat 830 can be fixed on the housing 100 by screws. That is, holes corresponding to the screws can be opened on the positioning seat 830. After determining the installation position of the four-way valve 300, corresponding holes are opened on the housing 100, and then the positioning seat 830 can be fixed on the housing by screws. Among them, a first engaging portion is provided on the positioning seat 830, and a second engaging portion is provided on the connecting member 810. The positioning seat 830 and the connecting member 810 can be detachably connected through the first engaging portion and the second engaging portion. After connecting the connecting member 810 with the four-way valve 300, the connecting member 810 and the positioning seat 830 are detachably connected, and the four-way valve 300 can be fixed on the housing 100. When it is necessary to repair or replace the four-way valve 300, only the first engaging portion and the second engaging portion need to be separated to remove the four-way valve 300 from the housing 100. Of course, the connecting member 810 used in this embodiment can still be an arc-shaped clamp or a positioning ring, as long as a second engaging portion cooperating with the first engaging portion is provided thereon.

[0050] In some possible embodiments, the second engaging portion includes connecting ears 820 located at both ends of the connecting member 810. The first engaging portion includes a card slot 850 that engages with the connecting ears 820 and a limiting plate 840 located on one side of the card slot 850. That is, at least one side of the card slot 850 close to the limiting plate 840 is open. The connecting ears 820 can enter or leave the card slot 850 through this opening. One end of the limiting plate 840 is rotatably connected to the positioning seat 830, and the other end is detachably connected to the groove wall of the card slot 850. When the movable end of the limiting plate 840 is separated from the groove wall of the card slot 850, the connecting ears 820 can enter the card slot 850 through the opening corresponding to the limiting plate 840. After the connecting ears 820 are inserted into the card slot 850, the movable end of the limiting plate 840 can be rotated to block the opening through the limiting plate 840, so that the connecting ears 820 cannot be separated from the card slot 850, thereby restricting the relative position of the connecting ears 820 and the card slot 850 through the limiting plate 840.

[0051] Of course, it can be understood that the movable end of the limiting plate 840 can be clamped with the groove wall of the card slot 850, or a first semi-cylinder can be provided at the end of the limiting plate 840, and a second semi-cylinder can be provided on the groove wall of the card slot 850. When the limiting plate 840 moves to the position where it blocks the opening of the card slot 850, the first semi-cylinder and the second semi-cylinder fit together to form a cylinder. At the same time, external threads are provided on both the first semi-cylinder and the second semi-cylinder. When the two are combined to form a cylinder, a complete thread is formed. At this time, a nut can be tightened on the cylinder formed by the two, so that the limiting plate 840 cannot be separated from the groove wall of the card slot 850.

[0052] Of course, it can be understood that the first engaging portion and the second engaging portion can also be connected in other ways, as long as the first engaging portion and the second engaging portion will not automatically separate after being engaged, and can stably support the four-way valve 300.

[0053] Among them, in order to better support the connecting member 810 and the four-way valve 300, two groups of card slots 850 can be arranged side by side, and the two groups are distributed in an up-and-down relationship. For the arc-shaped clamp, a connecting ear 820 can be arranged at each end thereof. For the positioning ring, a connecting ear 820 can be arranged on the side away from the four-way valve 300, so that the upper and lower ends of the connecting ear 820 respectively correspond to the two groups of card slots 850.

[0054] Specifically, L-shaped plates are arranged on the upper and lower sides of the positioning seat 830, and a card slot 850 with openings at both ends is formed between them and the positioning seat 830. Of course, the opposite sides of the two groups of card slots 850 are also open. During assembly, first fix the positioning seat 830 at an appropriate position on the housing 100, and then insert the connecting ear 820 into the card slot 850 from the openings at both ends of the card slot 850.

[0055] Exemplarily, when the connecting member 810 is an arc-shaped clamp, after fixing the positioning seat 830 on the housing 100, place the four-way valve 300 between the two groups of card slots 850. Of course, the extending direction of the four-way valve 300 is parallel to the length direction of the card slot 850. Finally, translate the arc-shaped clamp into the card slot 850 from the end of the card slot 850, and make the valve body 310 of the four-way valve 300 engage between the arc-shaped clamp and the positioning seat 830. Then rotate the limiting plate 840 to block the opening at the end of the card slot 850, so that neither the limiting plate 840 nor the four-way valve 300 can move relative to the positioning seat 830.

[0056] Exemplarily, when the connecting member 810 is a positioning ring, after fixing the positioning seat 830 on the housing 100, first sleuth a positioning ring on the valve body 310, then insert the connecting ear 820 corresponding to the positioning ring into the card slot 850 from the open end of the card slot 850, and then move another positioning ring along the length direction of the card slot 850, so that the connecting ear 820 corresponding to the positioning ring is inserted into the card slot 850, and at the same time the positioning ring is also sleuth on the other end of the valve body 310. Then rotate the movable end of the limiting plate 840 to block the open end of the card slot 850.

[0057] In some possible embodiments, a supporting portion 860 for supporting the connecting member 810 is provided on the card slot 850, and the supporting portion 860 at least partially wraps around the outside of the connecting member 810, that is, the supporting portion 860 is arc-shaped. When the connecting ear 820 is inserted into the card slot 850, the supporting portion 860 fits on the outer surface of the connecting member 810 to effectively support the connecting member 810. Of course, the supporting portion 860 should not wrap too many positions on the outside of the connecting member 810 so as not to affect the placement of the four-way valve 300.

[0058] In some possible embodiments, the connecting assembly further includes an elastic gasket 870. The elastic gasket 870 is located between the connecting member 810 and the valve body 310. The valve body 310 can be protected by the elastic gasket 870 to prevent the valve body 310 from being damaged due to friction with the connecting member 810. Among them, the elastic gasket can be made of common materials such as rubber, as long as it can reduce the friction and external force impact received by the valve body 310 to protect the valve body 310.

[0059] In some possible embodiments, the elastic gasket 870 is directly fixed on the connecting member 810. For example, for the elastic gasket 870 made of rubber, it can be directly fixed at the corresponding position of the connecting member 810 by means of hot melting or gluing. In addition, serrated positioning protrusions are provided on the side of the elastic gasket in contact with the valve body 310, and the friction force between the elastic gasket 870 and the valve body 310 can be increased through the positioning protrusions. While protecting the valve body 310, it can also prevent relative rotation between the valve body 310 and the connecting member 810, and improve the fixing effect of the connecting member 810 on the valve body 310.

[0060] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the 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 recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
