[0001] This application is based on and claims priority to patent application No. 202421678246.X, filed on July 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of water heaters, and in particular to multi-system water heater modules and heat pump systems. Background Technology

[0003] In existing water heater modules, the water system is simple, and the installation scenario is mostly wall-mounted, such as... Figure 1 As shown, the outlet pipe is generally set to the bottom. However, due to the different needs of users in different regions for heat pump systems, the installation scenarios for existing water heater modules are increasing. Existing single-system water heater modules can no longer meet multiple needs such as air conditioning, heating, and domestic hot water. When users have multiple needs, they can only achieve this by installing multiple water heater modules, resulting in a large installation space and multiple operation controls in the control system.

[0062] To make the objectives, technical solutions, and advantages of this embodiment clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0063] To facilitate understanding of this embodiment, a detailed description of this embodiment is provided below.

[0064] This embodiment provides a multi-system hot water heater module, including a housing 23 and at least two water circuit systems. Each water circuit system is installed inside the housing 23, and one water circuit system is connected to a first terminal device, while the other water circuit system is connected to a second terminal device. The first terminal device and the second terminal device are different.

[0065] This embodiment also provides a heat pump system, including a heat pump host, a first terminal device, a second terminal device, and the aforementioned multi-system water heater module. One of the water circuits in the multi-system water heater module is connected between the heat pump host and the first terminal device, and the other water circuit in the multi-system water heater module is connected between the heat pump host and the second terminal device.

[0066] like Figure 2 As shown, there are two water systems: a first water system 21 and a second water system 22. Both systems are housed within a casing 23. The first water system 21 is connected to a first terminal device, and the second water system 22 is connected to a second terminal device. The first and second terminal devices are different. In practical applications, the first terminal device is preferably a domestic water tank, and the second terminal device is preferably at least one of the following: an air conditioner, underfloor heating, or a radiator assembly. The specific configuration of the first and second terminal devices can be determined based on actual conditions, and will not be detailed further in this embodiment.

[0067] The aforementioned multi-system hot water unit module can accommodate multiple water circuit systems, each connected to different terminal devices. By integrating multiple water circuit systems, it meets the needs of various usage and installation scenarios, requires less installation space, is highly convenient to operate and control, improves installation and maintenance efficiency, and saves installation costs.

[0068] In one embodiment, the water system includes cold water pipes and hot water pipes disposed within the housing 23, with the ends of both pipes penetrating the side wall of the housing 23. In use, an external cold water source or terminal device supplies cold water to the heat pump unit via the cold water pipes. The cold water undergoes heat exchange as it flows through the heat pump unit, becoming hot water. The hot water then flows through the hot water pipes to the terminal device for user use or to supply heat to the indoor environment via the terminal device.

[0069] The ends of both the cold water and hot water pipes are located on the side wall of the housing 23. This ensures the flatness of the bottom of the housing 23 while achieving hot and cold water circulation. This allows the housing 23 and the multi-system hot water unit module to be used not only wall-mounted but also floor-mounted, thus meeting the needs of various usage and installation scenarios. In addition, since the ends of each pipe are located on the side wall of the housing 23 rather than the bottom, operators can directly perform installation and maintenance operations on the side of the housing 23 during installation and maintenance, making the operation more convenient and facilitating after-sales installation and maintenance.

[0070] In this embodiment, the hot water pipeline is equipped with a heater, a first check valve, and a flow switch, with the first check valve located on the inlet side of the heater; one of the hot water pipelines is equipped with a safety valve 226. When the heat pump unit supplies heat to the terminal device through the water system via the heater in the hot water pipeline, the heater can be turned off when the heat pump unit's heating capacity meets the requirements; when the heat pump unit's heating capacity does not meet the requirements, the heater can be activated to provide auxiliary heating to the hot water flowing through the hot water pipeline, thereby increasing the temperature of the hot water delivered to the terminal device, ensuring the heating effect on the terminal device, and thus improving the adjustability of the heat pump system and ensuring the heating effect of the heat pump system.

[0071] In this system, when the heat pump unit stops or starts operating, the first check valve, also known as a one-way valve, prevents hot water from flowing back into the heat pump unit. The flow switch, also known as a target flow switch, detects the fluid in the hot water pipes after it has been heated by the heater, effectively protecting the heater and preventing problems such as insufficient flow leading to heater dry burning and excessive pressure in the water system, thus ensuring the normal operation of the water system. The safety valve 226 is used to relieve pressure on the first water system 21 and the second water system 22, protecting the multi-system hot water modules.

[0072] like Figure 2As shown, the first water system 21 includes a first cold water pipe 211 and a first hot water pipe 212 disposed within the housing 23, with the ends of the first hot water pipe 212 and the first cold water pipe 211 both penetrating through the side wall of the housing 23; similarly, the second water system 22 includes a second cold water pipe 221 and a second hot water pipe 222 disposed within the housing 23, with the ends of the second hot water pipe 222 and the second cold water pipe 221 both penetrating through the side wall of the housing 23.

[0073] Among them, the heater located in the first hot water pipe 212 is the first heater 213, the first check valve is the first check valve A214, and the water flow switch is the first water flow switch 215; the heater located in the second hot water pipe 222 is the second heater 223, the first check valve is the first check valve B224, and the water flow switch is the second water flow switch 225; the safety valve 226 can be installed in the first hot water pipe 212 or the second hot water pipe 222.

[0074] like Figure 4 As shown, one of the cold water pipes is equipped with a pressure gauge 26, and the pressure gauge 26 is installed on the outer wall of the housing 23. By designing the pressure gauge 26 to be external, it is convenient to monitor it during after-sales service and daily use.

[0075] In this embodiment, the cold water pipeline is equipped with a water pump and a second check valve, with the second check valve located on the outlet side of the water pump. The water pump is used to ensure the flow of liquid in the cold water pipeline and to reduce the damage caused to the water pump by hot water flowing through the hot water pipeline, thus ensuring the stable operation of the water pump. The second check valve prevents water backflow from damaging the water pump, thus protecting it and further ensuring the stable operation of the water pump.

[0076] Among them, the water pump located in the first cold water pipeline 211 is the first water pump 216 and the second check valve is the second check valve A217, the water pump located in the second cold water pipeline 221 is the second water pump 227 and the second check valve is the second check valve B228.

[0077] In this embodiment, in the two water systems, one hot water pipe is equipped with a three-way valve 24, and the branch connector 241 of the three-way valve is connected to another hot water pipe through a hot water connection pipe 29; the two cold water pipes are connected by a cold water connection pipe 25 between the pipe sections located on the water pump inlet side.

[0078] Hot water connection pipe 29 is connected to the hot water pipes of the first water system 21 and the second water system 22 via a three-way valve 24, for connecting the first water system 21 and the second water system 22; under normal use, such as Figure 2As shown, the main path of the three-way valve 24, i.e., the first end (i.e., end A) and the second end (i.e., end B), are connected. The first hot water pipe 212 and the second hot water pipe 222 operate independently. When one set of terminal devices, such as the domestic water tank, reaches the required temperature, while the other set of terminal devices, such as the heating terminal, has a large demand that cannot be met, the branch path of the three-way valve 24, i.e., the first end (i.e., end A) and the third end (i.e. end C), are connected. The first hot water pipe 212 can then deliver hot water to the second hot water pipe 222 through the three-way valve 24, so that the first water system 21 and the second water system 22 can jointly provide a heat source or a cold source for the heating terminal, so as to quickly meet the user's heating or cooling needs. In addition, the three-way valve 24 facilitates the disassembly and assembly of the second water system 22. When the installation scenario changes, the three-way valve 24 can be used to directly disassemble and assemble the second water system 22. Furthermore, when three or more water systems need to be installed, the second water system 22 can be expanded by simply adding multi-way valve bodies or multiple three-way valves 24 in sequence.

[0079] Among them, such as Figure 2 As shown, a cold water connection pipe 25 is connected between the first cold water pipe 211 and the second cold water pipe 221. When the flow rate of cold water supplied to the heat pump host by one set of terminal devices, such as heating terminals, through the second cold water pipe 221 is insufficient, another set of terminal devices, such as domestic water tanks, can supplement the cold water flow to the second cold water pipe 211 through the first cold water pipe 211 and the cold water connection pipe 25, thereby ensuring the stable operation of each circulation system.

[0080] Specifically, such as Figure 2 As shown, the three-way valve 24 is located on the outlet side of the corresponding heater.

[0081] In this embodiment, the cold water connection pipe 25 is connected to the cold water pipe in the following specific form: For example... Figures 9-15 As shown, the multi-system hot water unit module also includes a T-pipe 100, which includes an inlet pipe section 110, a first outlet pipe section 120, and a second outlet pipe section 130. A nut 150 is rotatably fitted to the end of the first outlet pipe section 120. The inlet pipe section 110 is connected to one of the cold water pipes, and the nut 150 is threadedly connected to the inlet connector of the corresponding water pump. The second outlet pipe section 130 is connected to the cold water connection pipe 25. Based on the use of the T-pipe 100 to set up the cold water connection pipe 25, the first outlet pipe section 120 of the T-pipe 100 is screwed to the inlet connector of the water pump 216 via the nut 150, making disassembly and assembly convenient. Furthermore, no connecting pipe is needed between the water pump and the first outlet pipe section 120, reducing the distance between them and shortening the length of the cold water pipe. This improves the convenience and simplicity of the cold water pipe layout and reduces the space occupied by the cold water pipe within the housing 23 and its interference with other pipes.

[0082] Specifically, such as Figures 9-15 As shown, the tee pipe 100 can be installed in the first cold water pipe 211, and its nut 150 is threadedly connected to the inlet connector a12161 of the first water pump 216; similarly, the cold water connection pipe 25 and the second cold water pipe 221 can also be connected through the tee pipe 100. Specifically, the inlet pipe section 110 of the tee pipe 100 is connected to the second cold water pipe 221, the nut 150 is threadedly connected to the inlet connector b12271 of the second water pump 227, and the second outlet pipe section 130 is connected to the cold water connection pipe 25.

[0083] In this embodiment, one end of the hot water pipe and the cold water pipe are both installed through the first side wall 231 of the box, and the other end of both are installed through the second side wall 232 of the box. The ends of the hot water pipe and the cold water pipe located on the same side wall are arranged alternately along the width direction of the corresponding side wall. On the one hand, the cold water pipes and hot water pipes are concentrated at both ends on the first side wall 231 and the second side wall 232, while the other side walls of the housing 23 are flat. This improves the flexibility of the housing 23 during use and reduces the occurrence of situations where the housing 23 has pipe ports on all four side walls, resulting in a large space occupation and inability to be arranged against the wall. On the other hand, the ends of the pipes located on the same side wall are arranged vertically and staggered along the width of the side wall. That is, the ends of the pipes located on the same side wall are not collinear in the vertical direction. This makes full use of the space of the side wall and the width of the housing 23, improves the compactness of the pipe arrangement, and correspondingly reduces the overall volume of the housing 23 and the multi-system hot water unit module, making it miniaturized.

[0084] For ease of explanation, in this embodiment, the ports where the first hot water pipe 212, the first cold water pipe 211, the second hot water pipe 222, and the second cold water pipe 221 are connected to the heat pump host (or outdoor unit) are referred to as the first end, and the ports where the first hot water pipe 212, the first cold water pipe 211 are connected to the first terminal device, and the ports where the second hot water pipe 222, the second cold water pipe 221 are connected to the second terminal device are referred to as the second end.

[0085] Specifically, such as Figure 2 and Figure 3 As shown, the first cold water pipe 211 includes a first end 2111 and a second end 2112, the first hot water pipe 212 includes a first end 2121 and a second end 2122, the second cold water pipe 221 includes a first end 2211 and a second end 2212, and the second hot water pipe 222 includes a first end 2221 and a second end 2222; wherein, the first end 2111 of the first cold water pipe 211, the first end 2121 of the first hot water pipe 212, the first end 2211 of the second cold water pipe 221, and the first end 2221 of the second hot water pipe 222 all penetrate through the first side wall 231 of the housing 23, where the first side wall 231 is... Figure 2 From the perspective of the left side wall of the enclosure 23, the second ends 2112 of the first cold water pipe 211, 2122 of the first hot water pipe 212, 2212 of the second cold water pipe 221, and 2222 of the second hot water pipe 222 are all connected through the second side wall 232 of the enclosure 23. Here, the second side wall 232 is... Figure 2 The right side wall of box 23 in the view.

[0086] In one layout, the first water system 21 is located below the second water system 22. In another layout, the hot water pipes and cold water pipes can be centrally distributed. Specifically, the first hot water pipe 212 of the first water system 21 is located below the second hot water pipe 222 of the second water system 22, the first cold water pipe 211 of the first water system 21 is located below the second cold water pipe 221 of the second water system 22, and the second cold water pipe 221 is located below the first hot water pipe 212. That is, the first hot water pipe 212 and the second hot water pipe 222 are centrally distributed, the first cold water pipe 211 and the second cold water pipe 221 are centrally distributed, and the centrally distributed cold water pipes are placed below the centrally distributed hot water pipes.

[0087] In another layout, the cold water pipes and hot water pipes can be arranged as follows: (e.g.) Figure 9 As shown, the ends of the first cold water pipe 211, the first hot water pipe 212, the second cold water pipe 221, and the second hot water pipe 222, located on the same side wall, are arranged sequentially from bottom to top, and the first cold water pipe 211, the second cold water pipe 221, and the second hot water pipe 222 all extend laterally between the first side wall 231 and the second side wall 232; the first hot water pipe 212 includes a vertically extending vertical pipe section 2124 and a laterally extending section on the first side wall. The top end of the horizontal pipe section 2125 between the second side wall 231 and the second side wall 232 is connected to the end of the horizontal pipe section 2125 facing the first side wall 231, and the bottom end of the vertical pipe section 2124 is connected to the first side wall 231 through the first connecting pipe section 2123. The end of the horizontal pipe section 2125 facing the second side wall 232 is connected to the second side wall 232 through the second connecting pipe section 2126. The horizontal pipe section 2125 is located above the second hot water pipe 222.

[0088] In each water system, the end of the cold water pipe is located below the end of the hot water pipe. This arrangement is more in line with the operator's habit of arranging the cold and hot pipes, making it easier for the operator to assemble and maintain the cold and hot pipes, and reducing the assembly error rate.

[0089] In addition, three pipes—a first cold water pipe 211, a second cold water pipe 221, and a second hot water pipe 222—are arranged laterally and spaced from bottom to top. By providing a vertical pipe section 2124 extending vertically and a horizontal pipe section 2125 extending horizontally in the second hot water pipe 2122, while ensuring the vertical arrangement of both ends of each pipe, the first cold water pipe 211 and the second cold water pipe 221 can be arranged adjacently, thereby shortening the length of the cold water connection pipe 25 connecting the two. Furthermore, the horizontal pipe section 2125 of the first hot water pipe 212 can be arranged adjacently with the second hot water pipe 222, thereby shortening the length of the hot water connection pipe 29 connecting the two. This improves the compactness and ease of arrangement of each pipe, and reduces the size and space occupation of the multi-system hot water unit module.

[0090] On the other hand, with the first cold water pipe 211 and the second cold water pipe 221 arranged adjacent to each other and located in the lower area of ​​the housing 23, and the first water pump 216 arranged in the first cold water pipe 211 and the second water pump 227 arranged in the second cold water pipe 221, the center of the multi-system hot water heater module is positioned at the bottom, thereby improving the stability of the multi-system hot water heater module, and correspondingly improving its stability when placed on the ground as well as the stability of the installation and transportation process, reducing the occurrence of tipping damage to the multi-system hot water heater module.

[0091] On the other hand, the main pipe sections of each pipeline extend in a straight pipe shape with three horizontal and one vertical lines. Based on the above arrangement, there is no need to install complex-shaped S-pipes, U-pipes, or other bends that occupy a large amount of space, thereby shortening the pipeline length, reducing the space occupied by the pipeline, and improving the compactness of the pipeline layout. In addition, the above arrangement can effectively reduce the height required for each pipeline layout, thereby reducing the height of the cabinet and improving its applicability to installation scenarios. For example, multi-system hot water unit modules can be arranged under the windowsill to make full use of the space under the windowsill.

[0092] It should be noted that the aforementioned "lateral extension" is not limited to horizontal extension; any extension where the overall vertical tilt angle at both ends of the pipeline is less than 30° falls under the category of "lateral extension" as described in this application.

[0093] In this embodiment, as Figures 9-12As shown, a three-way valve 24 is provided in the transverse pipe section 2125. The main path between the first end (i.e., end A) and the second end (i.e., end B) of the three-way valve 24 is connected to the transverse pipe section 2125, and the branch connector 241 of the third end of the three-way valve 24 is connected to the second hot water pipe 222. The transverse pipe section 2125 and the second hot water pipe 222 both extend laterally and are arranged adjacent to each other. By setting the three-way valve 24 in the transverse pipe section 2125 and connecting it to the second hot water pipe 222 through the hot water connection pipe 29, the mutual auxiliary heating between the two circulation systems can be achieved by adjusting the passage of the three-way valve 24. This effectively shortens the length of the hot water connection pipe 29, reduces the space occupied by the hot water connection pipe 29, and improves its layout convenience.

[0094] In this embodiment, as Figure 12 and Figure 13 As shown, the multi-system hot water unit module also includes a first Y-type connector 200 located inside the housing. The openings of the first branch connector a1210 and the second branch connector a2220 of the first Y-type connector 200 both face the first side wall 231. One end of the second hot water pipe 222 facing the second side wall 232 is connected to the first branch connector a1210, and the third end of the three-way valve 24 is connected to the second branch connector a2220 through the hot water connection pipe 29. The first Y-type connector 200 is located near the second side wall 232, or the third branch connector a3230 of the first Y-type connector 200 is fixed to the second side wall 232.

[0095] The openings of the first branch connector a1210 and the second branch connector a2220 of the first Y-type connector 200 both face the first sidewall 231. The opening direction of the first branch connector a1210 is consistent with the extension direction of the second hot water pipe 222, and the two are approximately directly connected. The opening direction of the second branch connector a2220 is approximately perpendicular to the direction of the third end port of the three-way valve 24. The hot water connection pipe 29 may include a first pipe section 291 extending along the direction of the third end port of the three-way valve 24 and a second pipe section 292 extending along the opening direction of the first branch connector a1210. The ends of the first pipe section 291 and the second pipe section 292 facing each other are connected at an angle. The end of the first pipe section 291 away from the second pipe section 292 is approximately directly connected to the third end of the three-way valve 24, and the end of the second pipe section 292 away from the first pipe section 291 is approximately directly connected to the second branch connector a2220.

[0096] The installation of the first Y-type connector 200 can improve the simplicity of the layout of the second hot water pipe 222 and the hot water connection pipe 29, reduce pipe bends, improve the convenience of pipe layout and reduce its space occupation.

[0097] The connection arrangement of the third branch connector a3230 and the second side wall can be as follows: the opening of the third branch connector a3230 faces the second side wall 232, and the third branch connector a3230 is installed in the second side wall 232 through other pipelines; or the third branch connector a3230 extends outward from the second side wall 232 approximately in the direction facing the second side wall 232.

[0098] In this embodiment, the first sidewall 231 and the second sidewall 232 are arranged opposite each other in the left-right direction, and can be the left side plate 233 and the right side plate 234 of the housing 23, respectively. The first hot water pipe 212, the first cold water pipe 211, the second hot water pipe 222 and the second cold water pipe 221 all extend in the left-right direction to reduce the bending of each pipe, thereby shortening the length of each pipe and the space occupied, thereby improving the structural compactness of the multi-system hot water heater module, reducing its volume and space occupied, and improving the convenience of the layout of each pipe.

[0099] In this embodiment, the first cold water pipe 211 and the second cold water pipe 221 sequentially include a cold water pipe segment A extending from left to right, a cold water pipe segment B extending from front to back, and a cold water pipe segment C extending from left to right along their extension direction. The left end of the cold water pipe segment A is disposed through the first side wall, and the area between the rear side of the cold water pipe segment A and the left side of the cold water pipe segment B is a receiving space. The right end of the cold water pipe segment C is connected to the second side wall through the cold water pipe segment D. The vertical pipe segment is located behind the first cold water pipe, the second cold water pipe, and the second hot water pipe, and is housed in the receiving space. The water pump is located in the cold water pipe segment C.

[0100] Specifically, such as Figures 9-13 As shown, the first cold water pipe 211 includes, in sequence along its extension direction, a first cold water pipe segment A2113 extending from left to right, a first cold water pipe segment B2114 extending from front to back, and a first cold water pipe segment C2115 extending from left to right. The left end of the first cold water pipe segment A2113 is disposed through the first side wall 231, and the area between the rear side of the first cold water pipe segment A2113 and the left side of the first cold water pipe segment B2114 is the first accommodating space 10B. The right end of the first cold water pipe segment C2115 is connected to the second side wall 232 through the first cold water pipe segment D2116. The vertical pipe segment 2124 and the first connecting pipe segment 2123 are accommodated in the first accommodating space 10B.

[0101] The bottom end of the vertical pipe section 2124 faces downward. The first connecting pipe section 2123 is bent, with one end pointing upward and directly connected to the bottom end of the vertical pipe section 2124, and the other end extending towards and penetrating the first side wall 231. The first cold water pipe section A2113 of the first cold water pipe 211 is close to the first side wall 231, and the rear side of the first cold water pipe section A2113, the left side of the first cold water pipe section B2114, and the first side wall 231 form a first accommodating space 10B. The bent first connecting pipe section 2123 is located behind the first cold water pipe 211 and is accommodated in the first accommodating space 10B. The first cold water pipe section C2115 is moved backward towards the rear wall panel 235 of the housing 23 to create a larger first installation space 10C in front of it for the installation of components such as the first water pump 216. The extension of the first cold water pipe 211 not only facilitates the arrangement of the first hot water pipe 212, but also creates a larger first installation space 10C in front of the first cold water pipe section C2115 for the installation of components such as the first water pump 216. The pipes of the first cold water pipe 211 and the first hot water pipe 212 are simple, compactly arranged, and occupy little space.

[0102] Similarly, such as Figure 12 and Figure 13 As shown, the second cold water pipe 221 includes, in sequence, a second cold water pipe segment A2213 extending from left to right, a second cold water pipe segment B2214 extending from front to back, and a second cold water pipe segment C2215 extending from left to right along its extension direction. The left end of the second cold water pipe segment A2213 is installed through the first side wall 231. The area between the rear side of the second cold water pipe segment A2213 and the left side of the second cold water pipe segment B2214 is the second accommodating space 10D. The vertical pipe segment 2124 extends through the second accommodating space 10D. The right end of the second cold water pipe segment C2215 is connected to the second side wall 232 through the second cold water pipe segment D2216.

[0103] In the second cold water pipe 221, the second cold water pipe section A2213, the second cold water pipe section B2214 and the first side wall 231 form a second accommodating space 10D. The vertical pipe section 2124 passes through the second accommodating space 10D and passes behind the second cold water pipe 221, which can effectively reduce the pipe interference between the vertical pipe section 2124 and the second cold water pipe 221. Furthermore, the second cold water pipe section C2215 moves backward close to the rear wall plate 235 of the housing 23 to make way for a larger second installation space 10E in front of it for the installation of components such as the second water pump 227. The extension of the second cold water pipe 221 not only facilitates the arrangement of the first hot water pipe 212, but also creates a larger second installation space 10E in front of the second cold water pipe section C2215 for the installation of components such as the second water pump 227. The pipes of the second cold water pipe 221 and the first hot water pipe 212 are simple, compact, and occupy little space.

[0104] Specifically, such as Figures 9-13 As shown, a first heater 213 can be provided in the vertical pipe section 2124, and the first heater 213 extends through the second accommodating space 10D. The first heater 213 is arranged in the larger second accommodating space 10D, which can make full use of the second accommodating space 10D and reduce the interference between the first heater 213 and the pipe arrangement, thereby improving the structural compactness of the multi-system hot water heater module.

[0105] In this embodiment, as Figure 13 As shown, the second check valve A217 can be located in the first cold water pipe section C2115 and on the outlet side of the first water pump 216 to make full use of the first installation space 10C in front of the first cold water pipe section C2115; the second check valve B228 is located in the second cold water pipe section C2215 and on the outlet side of the second water pump 227 to make full use of the second installation space 10E in front of the second cold water pipe section C2215, thereby improving the structural compactness of the pipes and components inside the housing 23, and reducing its space occupation while ensuring the functionality of the multi-system hot water heater module.

[0106] In this embodiment, as Figure 12 and Figure 13 As shown, the multi-system hot water unit module also includes a second Y-type connector 700, a cold water connection pipe 25, and a T-type tee located inside the housing 23. The openings of the first branch connector b1710 and the second branch connector b2720 of the second Y-type connector 700 both face the first side wall 231, and the third branch connector b3730 of the second Y-type connector 700 is close to or fixed to the second side wall 232. The cold water pipe section D of the second cold water pipe, namely the second cold water pipe section D2216, is connected to the first branch connector b1710 at one end facing the second side wall 232, and one end of the cold water connection pipe 25 is connected to the second branch connector b2720. The inlet end of the T-type tee is connected to the first cold water pipe 211, and the outer peripheral wall of the first outlet end of the T-type tee is rotatably fitted with a nut 150, which is threadedly connected to the inlet connector a12161 of the first water pump 216. The second outlet end of the T-type tee is connected to the other end of the cold water connection pipe 25.

[0107] In this configuration, the openings of the first branch connector b1710 and the second branch connector b2720 of the second Y-type connector 700 both face the first sidewall 231. The opening direction of the first branch connector b1710 is consistent with the extension direction of the second cold water pipe 221 and the second cold water pipe segment D2216, and the two are approximately directly connected. The opening direction of the second branch connector b2720 is approximately perpendicular to the direction of the second outlet port of the T-type tee. The cold water connection pipe 25 may include a third pipe segment 251 extending along the direction of the second outlet port of the T-type tee and a fourth pipe segment 252 extending along the opening direction of the second branch connector b2720. The ends of the third pipe segment 251 and the fourth pipe segment 252 facing each other are connected at an angle. The end of the third pipe segment 251 away from the fourth pipe segment 252 is approximately directly connected to the second outlet port of the T-type tee, and the end of the fourth pipe segment 252 away from the third pipe segment 251 is approximately directly connected to the second branch connector b2720.

[0108] The installation of the second Y-type connector 700 can improve the simplicity of the layout of the second cold water pipe 221 and the cold water connection pipe 25, reduce pipe bends, improve the convenience of pipe layout and reduce its space occupation.

[0109] In this embodiment, as Figure 10 and Figure 12 As shown, a positioning seat 510 is fixed inside the housing 23. The pipe sections of the first cold water pipe 211, the first hot water pipe 212, the second cold water pipe 221, and the second hot water pipe 222 near the first side wall 231 are all detachably fixed to the positioning seat 510 through a limiting structure 520. The positioning seat 510 can support and position the pipe sections near the first side wall 231 from the rear side. The limiting structure 520 fixes the pipe sections near the first side wall 231 to the positioning seat 510, thereby improving the positional accuracy and stability of each pipe section within the housing 23. This ensures the correspondence between each pipe section and the through hole provided on the first side wall 231, and ensures the length of each pipe section extending to the left of the through hole or the matching connection between each pipe section and the joint provided on the first side wall 231.

[0110] In one implementation, such as Figure 5 , Figure 6 and Figure 8 As shown, the multi-system water heater module also includes an electrical control assembly, which is integrated into the electrical control base 27, and the electrical control base 27 is movably connected to the housing 23. Figure 5 As shown, an independently controlled electronic control assembly is provided. The electronic control base 27 has a box-like structure, and the electronic control assembly is integrated within the box 271 of the electronic control base 27. In practical applications, the electronic control base 27 is rotatably connected to the housing 23, and the entire assembly can be flipped upside down, for example, by using hinges 28. Figure 6 As shown, this facilitates subsequent maintenance of the components in each water system.

[0111] In this embodiment, as Figure 7 As shown, the multi-system water heater module also includes a front panel 238, which is pivotally connected to the housing 23 and configured to cover the opening of the housing 23. The central region of the outer surface of the front panel 238 has an inwardly recessed first recess 2381, and strip-shaped second recesses 2382 extend from the first recess 2381 toward each of the four corners of the front panel 238. On one hand, the first recess 2381 and the second recesses 2382 serve as a reinforcing structure to improve the structural strength of the front panel 238, thereby ensuring the shape of the front panel 238 and its sealing of the housing 23. On the other hand, the first recess 2381 and the second recesses 2382 are inwardly recessed relative to the edge region of the front panel 238. When the electrical control base 27 is installed in the opening region of the housing 23, while ensuring a stable connection between the edge region of the front panel 238 and the housing 23, the second recesses extend backward... The protruding first recess 2381 and second recess 2382 can also abut against the electronic control base 27, thereby improving the installation stability of the electronic control base 27. Furthermore, the heat of the electronic control base 27 can be dissipated outward through the front panel 238, thereby ensuring the stable operation of the internal electronic control assembly of the electronic control base 27. On the other hand, the first recess 2381 and second recess 2382, which are set with specific shapes to adapt to the shape of the front panel 238, can improve the visibility of the front panel 238 and the multi-system water heater module.

[0112] In this embodiment, as Figures 7-12 As shown, the box 23 has a top plate 236, a bottom plate 237, and a left side plate 233, a rear wall plate 235 and a right side plate 234 located between the two. When the first side wall 231 and the second side wall 232 are arranged in the left and right direction, the left side plate 233 serves as the first side wall 231, the right side plate 234 serves as the second side wall 232, and the front panel 238 covers the front side of the box 23.

[0113] In this embodiment, a buffer water tank is provided between the second water system 22 and the second terminal device. The buffer water tank can reduce the frequent start-stop of the compressor of the heat pump host, thereby protecting the compressor and improving the comfort and stability of the heat pump system.

[0114] In summary, the multi-system water heater module provided in this embodiment can accommodate multiple water systems, meeting more installation needs; in addition, a heat pump water supply module is used instead of a gas system, the structure is set to floor-standing, and pipes are connected on both the left and right sides to separate the domestic water pipes from the outdoor unit pipes, which facilitates after-sales maintenance; and multiple water systems are centrally controlled using a unified electrical control scheme, reducing the difficulty of operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
