[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Heat pump water heaters are primarily used to supply hot water, specifically by connecting to faucets, showers, and other domestic water outlets, and to underfloor heating pipes to meet the heating needs of a space. Typically, to ensure the stability and reliability of hot water flow, the heat pump water heater needs to be connected to faucets, showers, and underfloor heating pipes via pipes, valves, filters, and other water system components to adjust the hot water flow and filter the water. In related technologies, the pipes, valves, and filters are directly and independently installed on the user's wall. During installation, the water system needs to be designed and planned locally before installing the pipes, valves, and filters separately. This takes up more indoor space, affecting the layout of the room, and involves numerous installation steps, resulting in high installation costs, especially in the European market.

[0037] Therefore, referring to Figures 1 to 8 As shown, the first aspect of this utility model provides a heat pump device, such as a heat pump water heater, for supplying domestic hot water and meeting the heat demand for space heating, such as supplying circulating hot water to underfloor heating pipes.

[0038] Reference Figure 1 , Figure 2 and Figure 8As shown, the heat pump device includes a heat pump body 100, a hydraulic connection module 200, and a connection assembly 300. The heat pump body 100 includes a housing 110 and, within the housing 110, a first heat exchanger 120, a second heat exchanger 130, a compressor 140, a water pump 150, an air duct structure 160, a fan, a first pipe 170, and a second pipe 180. The first pipe 170 supplies refrigerant, and the second pipe 180 supplies water. The first pipe 170 connects the first heat exchanger 120 and the second heat exchanger 130, and the compressor 140 is connected to the first pipe 170. The refrigerant circulates within the first pipe 170, specifically starting from the first heat exchanger 120, passing sequentially through the second heat exchanger 130 and the compressor 140, and then returning to the first heat exchanger 120.

[0039] Understandably, the second pipe 180 is connected to the first heat exchanger 120, and the water pump 150 is connected to the second pipe 180. Typically, the outer casing 110 is also provided with a first water supply interface 111 and a first water return interface 112, which are respectively connected to the two ends of the second pipe 180. The water flows in the second pipe 180 from the first water return interface 112 through the first heat exchanger 120 to the first water supply interface 111.

[0040] Understandably, the first heat exchanger 120, water pump 150, and second pipe 180 are located on one side of the second heat exchanger 130, and the air duct structure 160 is located on the other side of the second heat exchanger 130, with the fan housed within the air duct structure 160. The top of the outer casing 110 is provided with an air outlet 113 and an air inlet 114. The air outlet 113 is connected to the air duct structure 160, and the air inlet 114 communicates with the interior of the outer casing 110 and is located on the side of the second heat exchanger 130 opposite to the air duct structure 160. Driven by the fan, air from outside the outer casing 110 enters the interior of the outer casing 110 through the air inlet 114, passes through the second heat exchanger 130 and the air duct structure 160, and is then discharged from the air outlet 113.

[0041] Understandably, during the operation of the heat pump equipment, the refrigerant is compressed to a high-temperature, high-pressure state by the compressor 140 and flows along the first pipe 170 to the first heat exchanger 120. Within the first heat exchanger 120, the refrigerant in the first pipe 170 exchanges heat with the water in the second pipe 180, transferring heat from the refrigerant to the water, thus raising the water temperature and providing hot water. After exchanging heat with the water, the refrigerant flows along the first pipe 170 to the second heat exchanger 130, where it exchanges heat with the air, transferring heat from the air to the refrigerant. After exchanging heat with the air, the refrigerant flows along the first pipe 170 to the compressor 140 for the next cycle. This cycle ensures that the heat pump body 100 can continuously supply hot water.

[0042] Reference Figure 2 , Figure 4 and Figure 6 As shown, the hydraulic connection module 200 includes a housing 210 and a fluid processing assembly 280. Specifically, the housing 210 is connected to a first water inlet 220, a first water outlet 230, a second water return 240, and at least one second water supply 250. Typically, the first water inlet 220 and the first water outlet 230 are located on one side of the housing 210, while the second water return 240 and the second water supply 250 are located on the other side of the housing 210 for easy connection. In this embodiment, the first water inlet 220 and the first water outlet 230 are located on the upper side of the housing 210, and the second water return 240 and the second water supply 250 are located on the lower side of the housing 210. It is understood that the first water inlet 220 is connected to the first water supply 111, and the first water outlet 230 is connected to the first water return 112.

[0043] Reference Figure 2 and Figure 6As shown, the fluid processing assembly 280 is disposed within the housing 210. The fluid processing assembly 280 includes pipes, which connect the first water inlet 220 to the second water supply 250, and the first water outlet 230 to the second water return 240. In other words, the first water inlet 220 is connected to the second water supply 250 via the fluid processing assembly 280, and the first water outlet 230 is connected to the second water return 240 via the fluid processing assembly 280. The fluid processing assembly 280 is used to filter the water, preventing impurities in the water returning to the heat pump body 100 from damaging the water pump 150 or clogging the second pipe 180, thus ensuring the stability and reliability of the water flow. For example, the fluid handling assembly 280 includes a filter 283 connected to a pipe between a first outlet port 230 and a second return port 240, so that water is filtered by the filter 283 and then returned to the heat pump body 100 through the first outlet port 230 and the first return port 112.

[0044] In some embodiments, the fluid processing assembly 280 is further used to control the flow rate and direction of water. For example, the fluid processing assembly 280 includes a check valve connected to the pipe between the first outlet port 230 and the second return port 240. The check valve only allows water to flow from the second return port 240 to the first outlet port 230, preventing backflow and thus controlling the flow direction of water. Alternatively, the fluid processing assembly 280 may also include at least two control valves 289, which are respectively connected to the pipe between the first inlet port 220 and the second supply port 250, and the pipe between the first outlet port 230 and the second return port 240. In this way, the flow rate of water can be controlled by the control valves 289.

[0045] Understandably, the second water supply interface 250 is connected to the inlet of the user's faucet, shower, or underfloor heating pipe to provide hot water. The second return interface 240 is connected to the outlet of the underfloor heating pipe to circulate the water and achieve circulating heating. Typically, to ensure a continuous water supply to faucets, showers, etc., the second return interface 240 is also connected to the tap water supply.

[0046] It is easy to understand that in order to simultaneously supply hot water to faucets, showers, and underfloor heating pipes, there can be multiple second water supply interfaces 250. Multiple second water supply interfaces 250 are connected to the first water inlet interface 220 through multi-way valves. At the same time, multiple second water supply interfaces 250 are respectively connected to faucets, showers, and underfloor heating pipes.

[0047] Reference Figure 2As shown, it can be understood that the connecting component 300 is connected to the outside of the housing 210 and is used to fix the hydraulic docking module 200. For example, the hydraulic docking module 200 can be quickly installed on the user's wall via the connecting component 300, or the hydraulic docking module 200 can be quickly assembled with the housing 110 of the heat pump body 100 via the connecting component 300.

[0048] Reference Figure 1 and Figure 2 As shown, it can be understood that the hydraulic connection module 200 is disposed on one side of the heat pump body 100. In this embodiment, the hydraulic connection module 200 is disposed on the lower side of the heat pump body 100. Specifically, the connecting component 300 is fixedly connected to the wall, so that the hydraulic connection module 200 is fixedly installed on the wall, and the heat pump body 100 is disposed above the hydraulic connection module 200 and fixedly installed on the connecting component 300. In this way, the heat pump body 100 and the hydraulic connection module 200 share the connecting component 300, which helps to reduce costs.

[0049] It is easy to understand that, generally speaking, the first water supply interface 111 and the first water return interface 112 are located on the lower side of the outer shell 110 of the heat pump body 100. By installing the hydraulic connection module 200 on the lower side of the heat pump body 100, it is convenient for the first water inlet interface 220 to connect with the first water supply interface 111, and for the first water outlet interface 230 to connect with the first water return interface 112.

[0050] In other embodiments, the hydraulic connection module 200 may also be located on the left or right side of the heat pump body 100. In this case, the hydraulic connection module 200 is fixedly installed on the wall via the connecting component 300, and the heat pump body 100 is fixedly installed on the wall via another bracket.

[0051] By setting up a hydraulic connection module 200, the fluid processing component 280 is integrated into the housing 210 of the hydraulic connection module 200, and the housing 210 is connected to the connection component 300. When installing the hydraulic connection module 200, the hydraulic connection module 200 is fixedly installed on the wall and arranged on one side of the heat pump body 100 through the connection component 300. The first water inlet 220 is connected to the first water supply 111 of the heat pump body 100, and the first water outlet 230 is connected to the first water return 112 of the heat pump body 100. This effectively simplifies the installation process, greatly saves installation time, reduces the labor intensity of installers, and effectively reduces installation costs.

[0052] It is easy to understand that since the hydraulic connection module 200 integrates the fluid handling component 280, there is no need to design and plan the water circuit layout during installation. Furthermore, the hydraulic connection module 200 is connected to the wall only through the connecting component 300, which reduces drilling and effectively saves installation time.

[0053] It's easy to understand that the integrated hydraulic connection module 200 occupies little space, effectively reducing its impact on the user's indoor layout. Furthermore, the housing 210 protects the fluid handling component 280, effectively isolating it from dust and other impurities, which helps improve the stability and reliability of the equipment.

[0054] Reference Figure 2 and Figure 5 As shown, the connection assembly 300 includes a fixing bracket 310 and a hanger 320. Specifically, the fixing bracket 310 is used to connect with the external environment of the hydraulic connection module 200. For example, the fixing bracket 310 is fixed to a wall using fasteners such as screws and bolts, or the fixing bracket 310 is installed on the outer casing 110 of the heat pump body 100. In this embodiment, the fixing bracket 310 is installed on the wall, making the connection more stable.

[0055] Reference Figure 2 , Figure 3 and Figure 5 As shown, the bracket 320 is connected to the top of the housing 210. Specifically, the bracket 320 is fixed to the top of the housing 210 using fasteners such as screws and bolts, or it can be fixed to the top of the housing 210 by welding. The bracket 320 is hooked to the fixed bracket 310. For example, the bracket 320 and the fixed bracket 310 are connected by hooks through hanging holes, or by two overlapping hanging plates. The key is to ensure a stable hook-and-loop connection between the bracket 320 and the fixed bracket 310, thus fixing the hydraulic connection module 200 to the wall. The hook-and-loop installation method is convenient for the hydraulic connection module 200.

[0056] Reference Figure 5 As shown, the fixed bracket 310 includes two vertical rods 311 and two horizontal beams 312. The two vertical rods 311 and the two horizontal beams 312 are respectively connected, and the vertical rods 311 and the horizontal beams 312 are arranged perpendicularly. The two vertical rods 311 are spaced apart horizontally, and the two horizontal beams 312 are also spaced apart horizontally. The vertical rods 311 are fixed to the wall using fasteners such as bolts, screws, and rivets, while the horizontal beams 312 extend beyond the wall and are typically perpendicular to the wall. This connection between the vertical rods 311 and the wall increases the number of connection points between the fixed bracket 310 and the wall, improving the installation stability and support capacity of the fixed bracket 310.

[0057] Reference Figure 1 and Figure 2As shown, in this embodiment, the heat pump body 100 is positioned above the hydraulic docking module 200 and fixedly installed on the connecting assembly 300. Specifically, the heat pump body 100 is fixedly installed on the crossbeam 312 using fasteners such as screws and bolts, allowing the crossbeam 312 to support the heat pump body 100. The hydraulic docking module 200 is hung on the crossbeam 312 via a bracket 320. Thus, the fixing bracket 310 can install both the heat pump body 100 and the hydraulic docking module 200, saving installation space, reducing the number of parts, saving installation time, and thus reducing installation costs.

[0058] Reference Figure 2 and Figure 3 As shown, it can be understood that the hanger 320 and the fixed bracket 310 are connected by two overlapping hanging plates. Specifically, the fixed bracket 310 includes two first hanging plates 313, which are respectively connected to opposite sides of two crossbeams 312, and the first hanging plates 313 extend along the length direction of the crossbeams 312, thus the two first hanging plates 313 are arranged at intervals. The two crossbeams 312 are parallel, so the length directions of the two first hanging plates 313 are also parallel. Correspondingly, there are two hangers 320, both of which are installed on the top of the housing 210, and the length direction of the hangers 320 is the same as the length direction of the first hanging plates 313, and the length directions of the two hangers 320 are parallel. Each of the two hangers 320 is provided with a second hanging plate 321, which extends along the length direction of the hanger 320, and the two second hanging plates 321 are respectively located on opposite sides of the two hangers 320. The two second mounting plates 321 respectively abut against the upper surfaces of the two first mounting plates 313. Therefore, the hydraulic docking module 200 is hung on the fixed bracket 310, which has a simple connection structure, is easy to process, convenient to install, and has good load-bearing capacity.

[0059] In simple terms, when installing the hydraulic connection module 200, first fix the mounting bracket 310 to the wall. Then, move the hydraulic connection module 200 and the two brackets 320 towards the wall along the length of the crossbeam 312, so that the two second mounting plates 321 are inserted into the space between the two crossbeams 312 and above the two first mounting plates 313. At this point, the two second mounting plates 321 and the two first mounting plates 313 are arranged correspondingly in the vertical direction, with the second mounting plates 321 located above the first mounting plates 313. Next, move the hydraulic connection module 200 and the two brackets 320 downwards until the two second mounting plates 321 respectively abut against the upper surfaces of the two first mounting plates 313. Finally, push the hydraulic connection module 200 towards the wall. This method is simple to operate, convenient to install, and improves installation efficiency, thereby saving installation time and reducing installation costs.

[0060] Reference Figure 2 and Figure 3 As shown, it can be understood that a limiting part 314 is provided at the front end of the first hanging plate 313. Specifically, along the length direction of the first hanging plate 313, the limiting part 314 is located at the end of the first hanging plate 313 away from the wall. The limiting part 314 has a folded plate structure and is bent upward, so that the limiting part 314 protrudes from the upper end surface of the first hanging plate 313. During the process of installing the hydraulic docking module 200 onto the fixed bracket 310, it is installed in place until the front end of the second hanging plate 321 moves to the rear side of the limiting part 314. Therefore, the limiting part 314 can restrict the second hanging plate 321 from moving forward and detaching from the first hanging plate 313. It is easy to understand that the rear side of the hydraulic docking module 200 is restricted from moving by the wall, thereby effectively improving the installation stability of the hydraulic docking module 200 and preventing the hydraulic docking module 200 from falling off, thus improving safety.

[0061] In other embodiments, the first mounting plate 313 is provided with limiting portions 314 at both ends along its length, that is, limiting portions 314 are provided at both the front and rear ends of the first mounting plate 313. When the hydraulic connection module 200 is installed on the fixed bracket 310, the first mounting plate 313 is positioned between the two limiting portions 314. Therefore, the two limiting portions 314 can limit the hydraulic connection module 200 from the front and rear sides respectively. On the one hand, it can prevent the hydraulic connection module 200 from moving forward and detaching from the first mounting plate 313, effectively improving the installation stability of the hydraulic connection module 200; on the other hand, during the process of pushing the hydraulic connection module 200 towards the wall, the limiting portion 314 located at the rear end of the first mounting plate 313 can restrict the hydraulic connection module 200 from moving further backward, thereby preventing the hydraulic connection module 200 from colliding with the wall and causing damage to the wall, such as causing dust to fall onto the wall or damage to tiles, effectively protecting the wall.

[0062] In other embodiments, the limiting part 314 may also be a protrusion, a protrusion bulge or other structure. The specific structural form of the limiting part 314 is not limited here. It is only necessary that the limiting part 314 protrudes from the upper end surface of the first hanging plate 313.

[0063] Reference Figure 1 and Figure 2 As shown, the fixed bracket 310 also includes two positioning parts 315. Specifically, the two positioning parts 315 are respectively connected to the two vertical rods 311, and the two positioning parts 315 are located on opposite sides of the two vertical rods 311 in the left-right direction. The positioning parts 315 are configured as a folded plate structure, and the positioning parts 315 are bent towards the front side of the vertical rods 311. The two positioning parts 315 respectively abut against the left side wall and the right side wall of the outer casing 110 of the heat pump body 100. Therefore, the two positioning parts 315 can limit the left and right sides of the heat pump body 100 respectively, which helps to improve the installation stability of the heat pump body 100.

[0064] It is easy to understand that by setting two positioning parts 315 that respectively abut against the left and right sides of the heat pump body 100, the distance between the two vertical rods 311 can be limited to a certain extent. That is to say, when the fixing bracket 310 is installed on the wall, the distance between the two vertical rods 311 can be accurately determined according to the width of the outer shell 110 of the heat pump body 100 in the left and right direction. This allows the distance between the two crossbeams 312 and the distance between the two first mounting plates 313 to be determined, so that the distance between the two first mounting plates 313 can be accurately matched with the distance between the two second mounting plates 321. There is no need to constantly adjust the distance between the two first mounting plates 313 based on the distance between the two second mounting plates 321, which helps to reduce the installation difficulty, thereby saving installation time and reducing installation costs.

[0065] Reference Figure 1 As shown, it can be understood that the outer wall of the housing 210 is flush with the outer wall of the heat pump body 100. Specifically, the outer wall of the housing 210 is flush with the outer wall of the outer casing 110, that is, the left side wall of the housing 210 is flush with the left side wall of the outer casing 110, the front side wall of the housing 210 is flush with the front side wall of the outer casing 110, and the right side wall of the housing 210 is flush with the right side wall of the outer casing 110. At the same time, the upper end of the housing 210 abuts against the lower end face of the outer casing 110. Therefore, the outer wall of the housing 210 and the outer wall of the outer casing 110 are continuously joined together, and from the appearance, the housing 210 and the outer casing 110 form a whole, which helps to improve aesthetics.

[0066] Understandably, to facilitate the water connection between the hydraulic connection module 200 and the heat pump body 100, the hydraulic connection module 200 also includes a first flexible pipe and a second flexible pipe. The first and second flexible pipes can be hoses or corrugated pipes, etc., and can be freely bent. The two ends of the first flexible pipe are connected to the first water inlet 220 and the first water supply 111, respectively, and the two ends of the second flexible pipe are connected to the first water outlet 230 and the first water return 112, respectively. It is easy to understand that when installing the hydraulic connection module 200, the first and second flexible pipes are first connected between the hydraulic connection module 200 and the heat pump body 100, respectively, and then the hydraulic connection module 200 is installed onto the fixed bracket 310. Since both the first and second flexible pipes can be bent freely, they will not hinder the pushing of the hydraulic connection module 200 towards the wall, facilitating installation.

[0067] Generally speaking, to facilitate docking, both the first flexible tube and the second flexible tube are reserved with a large length. After the hydraulic docking module 200 is installed in place, both the first flexible tube and the second flexible tube are accommodated between the hydraulic docking module 200 and the heat pump body 100.

[0068] Therefore, referring to Figure 2and Figure 4 As shown, it can be understood that a receiving cavity 216 is formed on the top of the housing 210. Specifically, the housing 210 includes a front panel 211, side panels 212, and a top plate 213, with two side panels 212 located on the left and right sides of the housing 210, respectively. The housing 210 also includes a base 215 and a back plate 214. The front panel 211, the two side panels 212, and the back plate 214 are all connected to the base 215, and the top plate 213 is connected between the front panel 211, the two side panels 212, and the back plate 214. The front panel 211 and the two side panels 212 protrude from the upper surface of the top plate 213. Therefore, the receiving cavity 216 is defined between the top plate 213, the front panel 211, the two side panels 212, and the bottom wall of the housing 110. The first water inlet 220 and the first water outlet 230 are both mounted on the top plate 213. Both the first flexible tube and the second flexible tube are housed within the receiving cavity 216, providing sufficient space between the hydraulic connection module 200 and the heat pump body 100 to accommodate the first flexible tube and the second flexible tube. This prevents the first flexible tube and the second flexible tube from obstructing the pushing of the hydraulic connection module 200 toward the wall, facilitating installation.

[0069] It is understood that the front panel 211 and the side panel 212 are detachably connected. For example, the front panel 211 and the side panel 212 are connected by snap-fit, or by locking mechanism, etc. When installing the hydraulic connection module 200, the front panel 211 can be removed first. After the hydraulic connection module 200 is installed in place, the front opening of the receiving cavity 216 is made visible, exposing the first flexible tube and the second flexible tube. This allows the installer to adjust the position of the first flexible tube and the second flexible tube, preventing excessive bending that could cause breakage or affect water flow. After adjusting the position of the first flexible tube and the second flexible tube, the front panel 211 can then be connected to the two side panels 212, facilitating installation.

[0070] Reference Figure 4 As shown, the hydraulic docking module 200 also includes an insulation structure 290, which is configured as EPP foam (i.e., expanded polypropylene), expanded polyurethane, or a thermal insulation coating. In this embodiment, the insulation structure 290 is configured as EPP foam, installed within the housing 210, and covering the upper and lower sides of the fluid handling assembly 280. Specifically, the insulation structure 290 includes two pieces of EPP foam, which are respectively installed on the inner side of the top plate 213 and the inner side of the chassis. Therefore, the insulation structure 290 can reduce heat loss and improve energy efficiency.

[0071] In other embodiments, the insulation structure 290 covers the four sides of the fluid handling assembly 280, that is, covers the upper, lower, left and right sides of the fluid handling assembly 280, or completely covers the fluid handling assembly 280, which can further reduce heat loss.

[0072] In other embodiments, the insulation structure 290 is configured as a heat-insulating coating, which is applied to the inner wall surface of the housing 210.

[0073] Reference Figure 6 As shown, the fluid handling assembly 280 includes a first pipe 281, a second pipe 282, a filter 283, and a first check valve 284. The first pipe 281 is connected to a first inlet port 220 and a second supply port 250 at its two ends, respectively. The second pipe 282 is connected to a first outlet port 230 and a second return port 240 at its two ends, respectively. Both the filter 283 and the first check valve 284 are connected to the second pipe 282. The filter 283 can be a magnetic filter, a microbubble filter, etc. The first check valve 284 is configured to allow fluid to flow from the first return port 112 through the second pipe 282 to the first outlet port 230, preventing backflow. Therefore, during the operation of the heat pump equipment, the hot water generated in the heat pump body 100 is sequentially output to the underfloor heating pipes, faucets, showers, etc., through the first water supply interface 111, the first water inlet interface 220, the first pipe 281, and the second water supply interface 250. The water from the underfloor heating pipes or the tap water supply end sequentially flows back to the heat pump body 100 for heating through the second return water interface 240, the second pipe 282, the filter 283, the second one-way valve 286, the first water outlet interface 230, and the first return water interface 112. Therefore, the filter 283 of the fluid handling component 280 filters the return water, effectively preventing foreign objects in the water from damaging the water pump 150 or clogging the second pipe 180, which helps to ensure the stability and reliability of the water flow. At the same time, the second one-way valve 286 can control the direction of water flow when it flows back to the heat pump body 100, preventing backflow. In other words, the fluid handling component 280 also has the function of controlling the direction of water flow.

[0074] Reference Figure 7As shown, it can be understood that in some embodiments, the housing 210 is also connected to a second water inlet 260 and a second water outlet 270. The second water inlet 260 is used to connect to the water supply end of other hot water heating equipment such as a wall-hung boiler, and the second water outlet 270 is used to connect to the water return end of other hot water heating equipment such as a wall-hung boiler. The fluid handling assembly 280 also includes a coupler 285, a second one-way valve 286, a third pipeline 287, and a fourth pipeline 288. The coupler 285 is connected to the first pipeline 281. Specifically, the first pipeline 281 includes a first pipe section 2811 and a second pipe section 2812. The two ends of the first pipe section 2811 are respectively connected to the first water inlet 220 and the secondary side water inlet of the coupler 285, and the two ends of the second pipe section 2812 are respectively connected to the secondary side water outlet of the coupler 285 and the second water supply interface 250. The two ends of the third pipe 287 are connected to the second inlet port 260 and the primary inlet port of the coupler 285, respectively. The two ends of the fourth pipe 288 are connected to the second outlet port 270 and the primary outlet port of the coupler 285, respectively. The second check valve 286 is connected to the fourth pipe 288. The second check valve 286 only allows water to flow from the coupler 285 through the fourth pipe 288 to the second outlet port 270, preventing backflow.

[0075] Therefore, by setting up the coupler 285, the heat pump body 100 is connected in parallel with other hot water heating devices such as wall-hung boilers. The heat pump body 100 and other hot water heating devices are highly coupled, enabling three operating modes: individual operation of the heat pump body 100 and the wall-hung boiler / other hot water heating devices, or simultaneous operation of both. Users can switch operating modes according to different usage needs to achieve precise control of the hot water temperature, with a wide adjustable range and amplitude. In other words, the fluid handling component 280 also has the function of coupling multiple hot water heating devices and regulating the hot water temperature.

[0076] It is understood that in some embodiments, to facilitate control of the hot water flow rate, the fluid processing assembly 280 also includes a control valve 289. For example, the first pipe 281, the second pipe 282, the third pipe 287, and the fourth pipe 288 are all connected to the control valve 289. The opening degree of the control valve 289 is used to adjust the hot water flow rate to meet different user water consumption needs. In other words, the fluid processing assembly 280 also has the function of adjusting the hot water flow rate.

However, the present utility model is not limited to the above embodiments.
