For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Firstly, in some embodiments, the utility model provides a heat pump hot water system, which comprises an outdoor main machine (not shown) and a hot water module, and the hot water module is independently arranged outside the outdoor main machine. And the hot water module and the outdoor main machine are connected through pipelines.

[0028] Please refer to Figures 1 to 4 , which shows the hot water module of an embodiment of the utility model, which at least comprises a shell 1, a water tank 2 and a through hole for penetrating the pipeline. The shell 1 encloses a cavity. The shell 1 comprises two short sides arranged oppositely, which are first short side 111 and second short side 112 respectively. The first short side 111 and the second short side 112 can be arranged in parallel and spaced apart. The water tank 2 is transversely arranged in the cavity. Specifically, the water tank 2 is approximately in the shape of a long cylinder, and the length direction of the water tank 2 is parallel to the ground. As shown in Figures 1 to 3As shown, in some embodiments, the housing 1 further comprises two opposite long sides 12, each of which is connected between the two short sides. The housing 1 further comprises a top cover 13 and a bottom plate 14, which are oppositely spaced apart and each of which is connected between the two short sides. The two long sides 12, the two short sides, the top cover 13 and the bottom plate 14 of the housing 1 are each provided with a panel, which together enclose a rectangular cavity. At least part of the through holes are arranged on the panel of the second short side 112 of the housing 1 and penetrate the inner and outer sides of the cavity along the thickness direction of the panel. Similarly, the first access hole 61 is arranged on the panel of the first short side 111. The water tank 2 is supported on the bottom plate 14. When installed, the bottom plate 14 is placed on the ground.

[0029] The through hole is an interface for passing a pipeline; that is, the through hole is an interface for passing a pipeline, a wire, etc. The through hole penetrates the inner and outer sides of the housing 1. The pipeline, wire, etc. passes through the through hole, which can be connected to the equipment in the cavity of the water tank 2 and the equipment outside the cavity of the outdoor main machine, the tap end, the water end (such as a shower), etc. The number of through holes is not limited, and at least part of the through holes are arranged on one of the first short side 111 and the second short side 112. That is, all the through holes can be arranged on the second short side 112; or all the through holes can be arranged on the first short side 111; or only part of the through holes can be arranged on the second short side 112, and the other part of the through holes can be arranged on the other position close to the second short side 112 and away from the side of the water tank 2; or only part of the through holes can be arranged on the first short side 111, and the other part of the through holes can be arranged on the other position close to the first short side 111 and away from the side of the water tank 2. Moreover, the two long sides 12 do not have the through hole for passing the pipeline.

[0030] Since at least part of the through holes for passing the pipeline are arranged on one of the two short sides of the housing 1, and the two long sides of the housing do not have the through hole, the pipeline can be arranged on one of the two short sides of the housing 1, avoiding the bending of the pipeline; when the hot water module is installed, only the arrangement relationship between the short side where the through hole is located and the outdoor main machine needs to be considered, and according to different arrangement requirements, the hot water module can be flexibly installed by turning over.

[0031] As Figure 3 and Figure 4As shown, in some embodiments, all the through holes for passing pipelines are arranged on the second short side 112. The first short side 111 can be provided with a first access opening 61. The water tank 2 can be opposite to the first access opening 61. That is, the first access opening 61 and the through holes for passing pipelines are respectively located on different two short sides. Specifically, one end face of the water tank 2 along its length direction is opposite to the first access opening 61. The position of the first access opening 61 is provided with a first cover plate 610 which is detachably or rotatably connected with the shell 1. When the first cover plate 610 is opened, one end face of the water tank 2 is exposed; when the first cover plate 610 is closed, the end face of the water tank 2 is covered and hidden. The operator can perform maintenance on the water tank 2 through the first access opening 61. Of course, in other embodiments, the first short side 111 can also not be provided with an access opening; or the first short side 111 is provided with the first access opening 61, but the water tank 2 does not need to be opposite to the first access opening 61. The first access opening 61 opposite to the water tank 2 is arranged on the first short side 111 opposite to the second short side 112, which is convenient for maintenance. In some embodiments, the two long sides 12 are both provided with decorative panels. When the hot water module is installed, since the two long sides 12 are not provided with through holes and access openings, the installation of pipelines will not be interfered; at the same time, the decorative panels are arranged on the long sides 12, the long sides 12 can be used as decoration, and play a role in decoration and beauty. The decorative panels of the two long sides 12 can be the same or different panels. As long as the surface of the shell 1 does not have a through hole for passing pipelines, it can be used as a decoration surface. Furthermore, the surface of the shell 1 does not have a through hole for passing pipelines, but has an access opening, which can also be used as a decoration surface.

[0032] As shown, Figures 1 to 4 The top cover 13 includes a first area which is defined by the vertical projection of the water tank 2 on the top cover 13. The through holes can be arranged on the second short side 112 and / or other positions of the top cover 13 except the first area. That is, the through holes can be all arranged on the second short side 112; or the through holes can be all arranged on the top cover 13 except the first area; or part of the through holes are arranged on the second short side 112, and the other part of the through holes are arranged on the top cover 13 except the first area. Since the first area is opposite to the upper side of the water tank 2, this position is not convenient for passing pipelines, and it is easy to cause the pipelines to be bent. In some embodiments, at least part of the through holes can also be arranged on the top cover 13 except the first area, and the other position is actually closer to the second short side, corresponding to the heat exchanger 9, the water pump unit 8 and the like arranged close to the second short side. Therefore, the pipelines connected with the heat exchanger 9 and the water pump unit 8 can also be arranged on the top cover 13 except the first area, and the situation of pipeline bending can be avoided as much as possible.

[0033] As shown, Figure 4As shown, in some embodiments, the through-hole includes a water pipe interface 3 for passing through a water pipe, a refrigerant interface 4 for passing through a refrigerant pipe, and an electrical interface 5 for passing through an electrical connection wire. The water pipe interface 3, refrigerant interface 4, and electrical interface 5 are at least partially located on the second short side 112 or the first short side 111. Specifically, the number of each of the water pipe interface 3, refrigerant interface 4, and electrical interface 5 is not limited; they can all be located on the second short side 112 or the first short side 111, or only partially on the second short side 112 or the first short side 111, with the remaining interfaces located at other positions near the second short side 112 or the first short side 111 and away from the water tank 2. Since the water pipe interface 3, refrigerant interface 4, and electrical interface 5 are concentrated on the second short side 112 or the first short side 111 of the outer casing 1, the corresponding water pipes can be centrally arranged on the second short side 112 or the first short side 111 of the outer casing 1, avoiding bends in the water pipes; the corresponding refrigerant pipes can also be centrally arranged on the second short side 112 or the first short side 111 of the outer casing 1, avoiding bends in the refrigerant pipes; the corresponding electrical connection wires can also be centrally arranged on the second short side 112 or the first short side 111 of the outer casing 1, avoiding bends in the electrical connection wires. In some other embodiments, the through hole may include only one or both of the water pipe interface 3, refrigerant interface 4, and electrical interface 5.

[0034] like Figures 4 to 7 As shown, in some embodiments, the hot water module further includes a water pump unit 8 and a heat exchanger 9 disposed within the cavity. The water pump unit 8 includes a circulating water pump 81 and a zero-cold water pump 82. Of course, in other embodiments, the water pump unit 8 may also include one or more water pumps.

[0035] The water pipe interface 3 comprises two first through holes 31 and two second through holes 32. The two first through holes 31 are respectively used for penetrating the water tank inlet pipe and the water tank outlet pipe. The two second through holes 32 are respectively used for penetrating the water pump inlet pipe and the water pump outlet pipe. The refrigerant interface 4 comprises two third through holes 43, which are respectively used for penetrating the refrigerant input pipe and the refrigerant output pipe. The water tank inlet pipe is connected to a cold water source (such as a tap or other tap water output end) at one end and to the water tank 2 at the other end. The water tank outlet pipe is connected to the water tank 2 at one end and to a water end (such as a shower head) at the other end. The water pump inlet pipe and the water pump outlet pipe are respectively connected to the zero cold water pump 82 of the water pump unit 8 at one end and to the water circulation loop at the other end, so that the zero cold water pump 82 is arranged on the water circulation loop. The zero cold water pump 82 is part of the circulating water system and is responsible for sucking cold water from the outside into the system, then processing it through filtration and other processes, and then delivering it to the heat source through the water pump. The refrigerant input pipe and the refrigerant output pipe are respectively connected to the heat exchanger 9 at one end and to the outdoor main unit at the other end. The heat exchanger 9 and the water tank 2 are connected by a heat exchanger outlet pipe 93 and a heat exchanger inlet pipe 94. The circulating water pump 81 is connected to the heat exchanger inlet pipe 94 between the water tank 2 and the heat exchanger 9.

[0036] Specifically, each water pipe comprises an inner pipe and an outer pipe. The inner pipe is a pipe segment located inside the cavity, and the outer pipe is a pipe segment located outside the cavity. The water tank inlet pipe comprises a first inlet inner pipe 21 arranged inside the cavity and a first inlet outer pipe (not shown) located outside the cavity. The water tank outlet pipe comprises a first outlet inner pipe 22 arranged inside the cavity and a first outlet outer pipe (not shown) located outside the cavity. The water pump inlet pipe comprises a second inlet inner pipe 821 arranged inside the cavity and a second inlet outer pipe (not shown) located outside the cavity. The water pump outlet pipe comprises a second outlet inner pipe 822 arranged inside the cavity and a second outlet outer pipe (not shown) located outside the cavity. The refrigerant input pipe comprises a refrigerant input inner pipe 91 arranged inside the cavity and a refrigerant input outer pipe located outside the cavity. The refrigerant output pipe comprises a refrigerant output inner pipe 92 arranged inside the cavity and a refrigerant output outer pipe located outside the cavity. The first inlet inner pipe 21, the first outlet inner pipe 22, the second inlet inner pipe 821, the second outlet inner pipe 822, the refrigerant input inner pipe 91, and the refrigerant output inner pipe 92 are all built into the cavity. When installing the pipeline, the first inlet outer pipe needs to be connected to the first inlet inner pipe 21 through one of the first through holes 31, the first outlet outer pipe needs to be connected to the first outlet inner pipe 22 through the other first through hole 31, the second inlet outer pipe needs to be connected to the second inlet inner pipe 821 through one of the second through holes 32, the second outlet outer pipe needs to be connected to the second outlet inner pipe 822 through the other second through hole 32, the refrigerant input outer pipe needs to be connected to the refrigerant input inner pipe 91 through one of the third through holes 43, and the refrigerant output outer pipe needs to be connected to the refrigerant output inner pipe 92 through the other third through hole 43.

[0037] The principle of the hot water module to prepare hot water is roughly as follows: the external high-temperature refrigerant provided by the outdoor main machine enters the heat exchanger 9 through the refrigerant input pipe (refrigerant input outer pipe and refrigerant input inner pipe 91), the cold water of the water tank 2 is driven by the circulating water pump 81 to enter the heat exchanger 9 through the heat exchanger water inlet pipe 94, the cold water is heated in the heat exchanger 9 by heat exchange with the high-temperature refrigerant, the heated hot water comes out of the heat exchanger water outlet pipe 93 and returns to the water tank 2, and the cooled refrigerant returns to the outdoor main machine through the refrigerant output pipe (refrigerant output inner pipe 92 and refrigerant input outer pipe). The heat exchanger 9 can be a double-pipe heat exchanger or other types of heat exchangers, which are not limited here.

[0038] In some embodiments, the water pump unit 8 and the heat exchanger 9 are arranged between the water tank 2 and the second short side 112. That is, the water pump unit 8 and the heat exchanger 9 are arranged on one side of the cavity close to the second short side 112; that is, the distance between the water pump unit 8 and the panel of the first short side 111 is greater than the distance between the water pump unit 8 and the panel of the second short side 112, and the distance between the heat exchanger 9 and the panel of the first short side 111 is also greater than the distance between the heat exchanger 9 and the panel of the second short side 112. In this way, the various water pipes and refrigerant pipes connected between the water tank 2, the water pump unit 8 and the heat exchanger 9 are concentrated in the direction close to the second short side 112, and pass through the through hole of the second short side 112, so that the arrangement of the pipes is concentrated close to the second short side 112, avoiding the bending of the pipes in the cavity.

[0039] In some embodiments, as shown in Figures 4 to 7 The hot water module further comprises an electric control unit 7 arranged in the cavity. The electric control unit 7 comprises an electric control box and electrical elements, wiring terminals and the like arranged in the electric control box. The electric control unit 7 can be fixed on the panel of the short side where the through hole is located, for example, the panel of the second short side 112. Specifically, the electric control box can be fixedly connected with the panel of the short side where the through hole is located, for example, the panel of the second short side 112, and the opening of the electric control box faces the outside of the cavity, and the electrical elements, wiring terminals and the like in the electric control box can be exposed outside through the second access hole 62. The position of the second access hole 62 is covered with a second cover plate 620, and the second cover plate 620 and the shell 1 are detachably or rotatably connected, and the electrical elements, wiring terminals and the like in the electric control box can be exposed by opening the second cover plate 620, and the electrical elements, wiring terminals and the like in the electric control box can be covered and hidden by closing the second cover plate 620.

[0040] Continuing with the embodiment as shown in Figure 4 The electric interface 5 comprises a plurality of fourth through holes 54 for passing through the electric connection lines (not shown). In some embodiments, an electric connector 540 can be installed at the fourth through hole 54 to facilitate the connection of the electric connection lines and the wiring terminals in the electric control box. The number of fourth through holes 54 is not limited. For example, Figure 4The shown embodiment is an example, and two fourth through holes 54 are provided, and two electrical connection lines can be arranged through the two fourth through holes 54. One end of the electrical connection line is connected to the electronic control unit 7, and the other end is connected to the outdoor main machine. In addition, the hot water module further comprises a second access hole 62 provided on the second short side 112, and the second access hole 62 is arranged opposite to the electronic control unit 7, and the operator can perform maintenance on the electronic control unit 7 through the second access hole 62 on the second short side 112. It can be understood that the second access hole 62 can also be arranged at other positions.

[0041] As shown in the drawings, Figure 4 In some embodiments, the two first through holes 31 for arranging the water tank inlet pipe and the water tank outlet pipe, the two second through holes 32 for arranging the water pump inlet pipe and the water pump outlet pipe are all arranged on the left side of the electrical interface 5, and the two third through holes 43 for arranging the refrigerant input pipe and the refrigerant output pipe are all arranged on the right side of the electrical interface 5. That is, one part of the water pipe interface 3 and the refrigerant interface 4 are respectively arranged on the two sides (which can be opposite sides) of the electrical interface 5. As shown in the drawings, Figure 8 In some embodiments, the two first through holes 31 for arranging the water tank inlet pipe and the water tank outlet pipe, the two second through holes 32 for arranging the water pump inlet pipe and the water pump outlet pipe are all arranged on the left side of the electrical interface 5, and the two third through holes 43 for arranging the refrigerant input pipe and the refrigerant output pipe are all arranged on the right side of the electrical interface 5. That is, one part of the water pipe interface 3 and the refrigerant interface 4 are respectively arranged on the two sides (which can be opposite sides) of the electrical interface 5. As shown in the drawings,

[0042] In some embodiments, the panel on each short side is provided with at least two mounting positions 113 for mounting the connecting member 114, and the two mounting positions 113 are respectively arranged close to the two long sides 12. The connecting member 114 close to the long side 12 can be used to connect the shell 1 and the wall surface. In this way, when the hot water module is flipped in the horizontal direction, no matter which position it is flipped to, the shell 1 can be fixed to the wall surface through the connecting member 114 close to the long side 12, which is beneficial for flexible flipping installation of the hot water module.

[0043] Alternatively, as shown in the drawings, Figure 9 In some embodiments, the panel on each short side is provided with at least two mounting positions 113 for mounting the connecting member 114, and the two mounting positions 113 are respectively arranged close to the two long sides 12. The connecting member 114 close to the long side 12 can be used to connect the shell 1 and the wall surface. In this way, when the hot water module is flipped in the horizontal direction, no matter which position it is flipped to, the shell 1 can be fixed to the wall surface through the connecting member 114 close to the long side 12, which is beneficial for flexible flipping installation of the hot water module. Figure 9In the orientation of the panel, the mounting position 113 on the lower first short side 111 is located near the right long side 12, and the mounting position 113 on the upper second short side 112 is located near the left long side 12. That is, the mounting positions 113 on the two short sides are diagonally arranged. In this way, when the hot water module is flipped horizontally, regardless of its position, the outer casing 1 can be fixed to the wall by a single connector 114. However, by providing at least two mounting positions 113 on each short side panel, the hot water module can be fixed to the wall by at least two symmetrical connectors 114 regardless of its horizontal position, resulting in more even force distribution on the outer casing 1.

[0044] Furthermore, in some embodiments, at least one of the panels on the shorter side is provided with a mounting position 113 near the ground. A connector 114 near the ground can be used to connect the housing 1 to the ground.

[0045] It should be noted that when the distance between a mounting position 113 and the ground is less than the distance between it and the center point (e.g., the centroid) of the panel it is located on, the mounting position 113 can be considered "close to the ground". Similarly, when the distance between a mounting position 113 and the long side 12 is less than the distance between it and the center point (e.g., the centroid) of the panel it is located on, the mounting position 113 can be considered "close to the long side 12". For example, as... Figures 1 to 4 In the illustrated embodiment, the first short side 111 and the second short side 112 of the outer casing 1 each have three mounting positions 113. One mounting position 113 is located near the ground, and the other two mounting positions 113 are located near the two long sides 12, respectively. The mounting position 113 near the ground is used to fix the outer casing 1 to the ground, and the mounting positions 113 near the long sides 12 are used to fix the outer casing 1 to the wall. Each mounting position 113 is used to install at least one connector 114. The connector 114 can be a lifting lug or other auxiliary installation component. Each mounting position 113 may include two spaced-apart mounting holes. Of course, the structure of the mounting position 113 can be adapted to the structure of the connector 114. For different layout requirements, one or more suitable mounting positions 113 can be selected from the multiple mounting positions 113 to install the connector 114, and then the connector 114 can be fixed to the ground or wall to complete the installation of the hot water module. Therefore, multiple installation positions 113 can adapt to different layout requirements, making it convenient to determine the installation direction and fixed position of the hot water module according to the installation site conditions, and facilitating the flexible flipping installation of the hot water module.

[0046] It can be understood that the above embodiments only express the preferred embodiments of the utility model, the description is more specific and detailed, but it can not be understood as the limitation of the utility model patent scope; it should be pointed out that for ordinary skilled person in the art, the above technical features can be freely combined without departing from the concept of the utility model, and a number of modifications and improvements can be made, which belong to the protection scope of the utility model; therefore, any equivalent transformation and modification within the scope of the utility model patent claim should belong to the scope of the utility model patent claim.
