[0036] In the description of the embodiments of the present application, it should be noted that the terms "first direction" and "second direction" are based on the orientation or positional relationship shown in the Figure 1 , the Figure 2 and the Figure 3 shown orientation or positional relationship. The terms "height direction", "top", and "bottom" are based on the orientation or positional relationship shown in the Figure 1 shown orientation or positional relationship. These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the embodiments of the present application.

[0037] The embodiments of the present application provide a heat pump system, and the heat pump system includes a hydraulic module.

[0038] The heat pump system includes, but is not limited to, heat pump water heaters, heat pump air conditioners, heat pump floor heating, heat pump multi - supply (such as air - conditioner and floor - heating dual - supply, air - conditioner, floor - heating and hot - water triple - supply), etc.

[0039] The heat pump system is provided with a water circulation pipeline. The main function of the hydraulic module is to exchange heat with the water from the water circulation pipeline to obtain hot water or cooling water, and the heat - exchanged water is then transported through the water circulation pipeline to a water storage device such as a water tank of the heat pump system or to terminals such as fan coils, floor heating pipes, and radiators.

[0040] Please refer to Figures 1 to 3 , the hydraulic module of the embodiments of the present application includes a box structure, and the box structure includes a box assembly and a panel 200.

[0041] The box body assembly 100 includes a box body 10 having a maintenance opening 10a and a first clamping portion 20 provided on the box body 10. The first clamping portion 20 is one of a first clamping groove and a first clamping hook. The panel 200 includes a plate body 210 and a second clamping portion 220 provided on the plate body 210. The second clamping portion 220 is the other of the first clamping groove and the first clamping hook. That is to say, it can be that the first clamping portion 20 is the first clamping groove. The plate body 210 covers the maintenance opening 10a. The first clamping hook is clamped and matched with the first clamping groove, and the plate body 210 is fixedly connected to the box body 10.

[0042] That is to say, in addition to clamping, the panel 200 and the box body assembly 100 are also fixedly connected by fasteners such as screws and bolts. Among them, the first clamping portion 20 provided on the box body 10 and the second clamping portion 220 provided on the plate body 210 are clamped and matched to realize the clamping of the panel 200 and the box body assembly 100. When the first clamping portion 20 is the first clamping groove, the second clamping portion 220 is the first clamping hook that is clamped and matched with the first clamping groove. When the first clamping portion 20 is the first clamping hook, the second clamping portion 220 is the first clamping groove that is clamped and matched with the first clamping hook.

[0043] When the panel 200 is removed from the box body assembly 100, the maintenance opening 10a is exposed to the external environment. An operator can perform maintenance on the components arranged in the box body 10, such as water pumps, pipelines, heat exchangers, etc. through the maintenance opening 10a.

[0044] Since the box body assembly 100 is provided with the first clamping portion 20, the panel 200 is provided with the second clamping portion 220, and the first clamping portion 20 is one of the first clamping groove and the first clamping hook, and the second clamping portion 220 is the other of the first clamping groove and the first clamping hook. Therefore, during the process of removing the panel 200, only the fixed connection between the plate body 210 of the panel 200 and the box body 10 of the box body assembly 100 needs to be released first, and then the first clamping hook is disengaged from the first clamping groove, and the panel 200 can be removed from the box body assembly 100. When the panel 200 needs to be installed, only the first clamping hook needs to be clamped and matched with the first clamping groove first, and then the plate body 210 of the panel 200 and the box body 10 of the box body assembly 100 are fixedly connected. The disassembly and assembly process of the panel 200 is simple and convenient, which greatly improves the convenience of disassembly and assembly of the panel 200.

[0045] In addition, since the first clamping hook is clamped and matched with the first clamping groove, it can also play a certain fixing role on the panel 200. Therefore, only a small number of fasteners (such as 1 to 3) are needed to ensure that the plate body 210 of the panel 200 and the box body 10 of the box body assembly 100 can be effectively fixedly connected. Thus, the number of fasteners used can also be reduced, and the disassembly and assembly efficiency of the panel 200 can be improved.

[0046] In one embodiment, please refer to Figure 1 and Figure 3 , for the box structure where the first engaging portion 20 is a first slot and the second engaging portion 220 is a first hook, the first slot can penetrate through the box body 10. A clamping notch 200a is formed between the first hook and the plate body 210. When the first hook is engaged with the first slot, a part of the structure of the first hook passes through the first slot, and a part of the box body 10 located on the periphery of the first slot is clamped into the clamping notch 200a. That is, by clamping a part of the box body 10 between the first hook and the plate body 210, the clamping of the box assembly 100 and the panel 200 is achieved. When it is necessary to release the engagement between the first hook and the first slot, the operator only needs to move the panel 200 so that the part of the box body 10 clamped into the clamping notch 200a exits from the clamping notch 200a, and then withdraw the first hook from the first slot. This kind of engaging and cooperating method is convenient for the operator to operate.

[0047] In some other embodiments, it can also be that the second engaging portion 220 is a first slot, the first slot penetrates through the plate body 210, the first engaging portion 20 is a first hook, a clamping notch 200a is formed between the first hook and the box body 10, a part of the structure of the first hook passes through the first slot, and a part of the plate body 210 located on the periphery of the first slot is clamped into the clamping notch 200a.

[0048] In one embodiment, please refer to Figures 1 to 3 , the box body 10 includes a chassis 11 and two side plates 12. The two side plates 12 are arranged on opposite sides of the chassis 11 along the first direction. The maintenance opening 10a is located on the side of the box body 10 opposite to the chassis 11. At least one of the two side plates 12 is provided with the first engaging portion 20, and the second engaging portion 220 corresponds to the first engaging portion 20 one by one.

[0049] That is to say, among the two side plates 12, at least one side plate 12 is clamped with the panel 200.

[0050] Preferably, please refer to Figure 1 , both of the two side plates 12 are clamped with the panel 200. That is to say, both of the two side plates 12 can be provided with the first engaging portion 20.

[0051] In addition, one or more first engaging portions 20 can be provided on the same side plate 12. The number of the second engaging portions 220 on the panel 200 is the same as that of the first engaging portions 20, and the second engaging portions 220 and the first engaging portions 20.

[0052] Please refer to Figures 1 to 3, on one side of each side plate 12 close to the panel 200, there may be a flanging 121 formed by folding. A first clamping portion 20 is respectively arranged on each flanging 121. The outer surface of the flanging 121 facing the panel 200 may be parallel to the panel 200, which is not only convenient for the clamping cooperation between the first clamping portion 20 and the second clamping portion 220, but also after the first clamping portion 20 and the second clamping portion 220 are clamped and cooperated, the flanging 121 can be attached to the panel 200 to enhance the stability of the overall structure.

[0053] Please refer to Figure 2 and Figure 3 , the first card slot may extend along a second direction intersecting the first direction, where, Figure 2 as shown, the first direction is perpendicular to the second direction. In some other embodiments, the first direction may also be obliquely intersecting with the second direction.

[0054] The first card slot includes an introduction section 10b1 and a clamping section 10b2 located on one side of the introduction section 10b1 along the second direction. The dimension of the introduction section 10b1 along the first direction is larger than the dimension of the clamping section 10b2 along the first direction, and the first hook is snapped into the clamping section 10b2.

[0055] Specifically, during the operation of clamping and cooperating the first hook with the first card slot, first insert the first hook into the introduction section 10b1, and then snap the first hook from the introduction section 10b1 into the clamping section 10b2 to complete the clamping cooperation between the first hook and the first card slot. Among them, the introduction section 10b1 with a larger dimension along the first direction can be more convenient for the first hook to be inserted into the introduction section 10b, while the clamping section 10b2 with a smaller dimension along the first direction can effectively prevent the first hook from disengaging from the first card slot to improve the stability of the clamping.

[0056] Please continue to refer to Figure 1 and Figure 3 , when the first clamping portion 20 is the first card slot, in the installed state of the box body structure, the clamping section 10b2 may be located below the introduction section 10b1 along the height direction of the box body structure.

[0057] The installed state refers to the state of the box body structure after the hydraulic module is installed in the user's residence.

[0058] In an installed state (for example, the chassis 11 is installed facing the wall), the second direction is parallel or substantially parallel to the height direction of the box body structure in the installed state (for example, the included angle between the second direction and the height direction is greater than 0 degrees and less than or equal to 10 degrees).

[0059] Since the panel 200 has a tendency to move downward under the action of gravity, when the first clamping portion 20 is a first clamping slot, the clamping section 10b2 is located at the lower side of the introduction section 10b1 along the height direction of the box structure, and after the first clamping hook is inserted into the introduction section 10b1, the first clamping hook can be automatically moved from the introduction section 10b1 into the clamping section 10b2 under the action of the gravity of the panel 200, so that the first clamping hook and the clamping section 10b2 can be easily clamped and matched. In addition, in the process of removing the panel 200, after the operator removes the fastener, the first clamping hook can still be firmly clamped and matched with the clamping section 10b2 under the action of the gravity of the panel 200, and the operator needs to push the panel 200 upward to push the first clamping hook into the introduction section 10b1, thereby better preventing the panel 200 from falling due to the first clamping hook automatically escaping from the first clamping slot.

[0060] In other embodiments, when the second engaging portion 220 is a first engaging groove, when the box structure is in the installed state, the engaging section 10b2 may be located on the upper side of the introducing section 10b1 along the height direction of the box structure.

[0061] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 The box body 10 may be provided with two cover plates 13, and the two cover plates 13 and the two side plates 12 together enclose an inspection opening 10a. The bottom plate 11 is located on a side of the box body 10 away from the inspection opening 10a.

[0062] Each side panel 12 includes a main body 122 and a third clamping portion 122a arranged on the main body 122, the third clamping portion 122a is one of the second hook and the second slot 122a, each cover plate 13 includes a cover body 131 and a fourth clamping portion 132 arranged on the cover body 131 and corresponding to the third clamping portion 122a one by one, the fourth clamping portion 132 is the other of the second hook and the second slot 122a, and the second hook is clamped and matched with the second slot 122a.

[0063] That is to say, the side plate 12 and the cover plate 13 are engaged with each other through the second hook and the second slot 122a that cooperate with each other. When the second slot 122a is provided on the main body 122, the cover body 131 is correspondingly provided with a second hook that can be engaged with the second slot 122a. When the second hook is provided on the main body 122, the cover body 131 is correspondingly provided with a second slot 122a that can be engaged with the second hook.

[0064] The way in which the second hook and the second slot 122a are snap-fitted together can be the same or similar to the way in which the first hook and the first slot are snap-fitted together, that is, the second hook can adopt the same or similar structure as the first hook, and the second slot 122a can adopt the same or similar structure as the first slot, which will not be repeated here.

[0065] In addition, not only are the side plates 12 and the cover plate 13 fastened together by the third fastening portion 122a and the fourth fastening portion 132, but each side plate 12 is also fixedly connected to the cover plate 13 by fasteners. When it is necessary to remove the cover plate 13, it is only necessary to first release the fixed connection between the cover plate 13 and the side plates 12, and then disengage the second hook from the second slot 122a. When it is necessary to install the cover plate 13, it is only necessary to first engage the second hook with the second slot 122a in a snap-fit manner, and then fixedly connect the cover plate 13 to each side plate 12. The operation method is simple and convenient, effectively improving the convenience of disassembling and assembling the cover plate 13.

[0066] In one embodiment, please refer to Figure 1 、 Figure 4 and Figure 5 . When the box structure is in the installed state, the two cover plates 13 can be respectively located on the top side and the bottom side of the box structure in the height direction, and the inspection opening 10a is located between the two cover plates 13.

[0067] The plate body 210 can be fixedly connected to the cover plate 13 located at the bottom side. Generally speaking, the installation position of the hydraulic module is relatively high, such as near the indoor ceiling. Therefore, fixedly connecting the plate body 210 to the cover plate 13 located at the bottom side not only makes it more convenient to release the fixed connection between the plate body 210 of the panel 200 and the box 10 of the box assembly 100, but also facilitates the installation of fasteners when fixedly connecting the plate body 210 of the panel 200 to the box 10 of the box assembly 100.

[0068] Please continue to refer to Figure 1 、 Figure 4 and Figure 5 . The chassis 11 can be provided with a back plate portion 111 and a bottom plate portion 112. The back plate portion 111 is located on the side of the two side plates 12 away from the inspection opening 10a, and the bottom plate portion 112 is located at the bottom side and is fixedly connected to the cover plate 13 on the same side. That is to say, the bottom plate portion 112 can be fixedly connected to the cover plate 13 located at the bottom side to improve the installation reliability of the cover plate 13 located at the bottom side.

[0069] Please continue to refer to Figure 2 . Each side plate 12 can include a fifth fastening portion 122b provided on the main body 122. The fifth fastening portion 122b is one of a third hook and a third slot. The chassis 11 is provided with a back plate portion 111 and a bottom plate portion 112. The chassis 11 further includes a sixth fastening portion 113 provided on the back plate portion 111 and corresponding to the fifth fastening portion 122b one by one. The sixth fastening portion 113 is the other of the third hook and the third slot, and the third hook is engaged with the third slot in a snap-fit manner.

[0070] That is to say, the main body 122 and the back plate part 111 are engaged with each other through a third hook and a third slot that cooperate with each other. When the third slot is provided on the main body 122, the back plate part 111 is correspondingly provided with a third hook that can be engaged with the third slot. When the third hook is provided on the main body 122, the back plate part 111 is correspondingly provided with a third slot that can be engaged with the third hook.

[0071] The engaging manner of the third hook and the third slot can be the same as or similar to the engaging manner of the first hook and the first slot, that is, the third hook can adopt a structure the same as or similar to that of the first hook, and the third slot can adopt a structure the same as or similar to that of the first slot, which will not be elaborated here.

[0072] In addition, between the side plate 12 and the chassis 11, not only are they engaged through the sixth engaging part 113 and the fifth engaging part 122b, but each side plate 12 is also fixedly connected to the bottom plate part 112 through fasteners. When it is necessary to remove the side plate 12, it is only necessary to release the fixed connection between the bottom plate part 112 and the side plate 12, and then disengage the third hook from the third slot. When it is necessary to install the side plate 12, it is also only necessary to first engage the third hook with the third slot, and then fixedly connect the bottom plate part 11 and each side plate 12. The operation method is simple and convenient, effectively improving the convenience of disassembling and assembling the side plate 12.
