[0027] Please refer to Figures 1 to 4 , the hot water module of an embodiment of the utility model includes shell 1, water tank 2, heat exchanger 3 and water pump unit 4. Shell 1 is surrounded with a cavity. Water tank 2 is transversely arranged in the cavity. That is, water tank 2 is horizontally arranged in the cavity. Specifically, water tank 2 is substantially long barrel, and the length direction of water tank 2 is parallel to the ground. Heat exchanger 3 is arranged in the cavity, and is located on one side of the length direction of water tank 2. Water pump unit 4 is arranged in the cavity, and water pump unit 4 and heat exchanger 3 are located on the same side of the length direction of water tank 2. For example, as shown in the embodiment of the figure, water tank 2 is located on the left side of the cavity, and heat exchanger 3 and water pump unit 4 are located on the right side of the cavity, that is, water pump unit 4 and heat exchanger 3 are located on the right side of water tank 2. Heat exchanger 3 can be a double-pipe heat exchanger or other types of heat exchanger, which is not limited here. Figures 2 to 4

[0028] Among them, heat exchanger 3 and outdoor main machine are connected by pipeline. Water tank 2 and heat exchanger 3 are connected by pipeline. Water pump unit 4 is connected with water tank 2 and heat exchanger 3 by pipeline. Water tank 2 is in fluid communication with cold water source (such as tap water end of faucet) through external pipeline to access cold water. The principle of hot water module preparing hot water is as follows: the external high-temperature refrigerant provided by outdoor main machine enters heat exchanger 3, and the cold water of water tank 2 enters heat exchanger 3 under the driving force of water pump unit 4, and the cold water is heated in heat exchanger 3 by heat exchange with high-temperature refrigerant, and the heated hot water returns to water tank 2, and the cooled refrigerant returns to outdoor main machine. Water pump unit 4 provides power for the circulation of water flow between water tank 2 and heat exchanger 3.

[0029] ​In summary, the water tank 2, the heat exchanger 3 and the water pump unit 4 are integrated in the shell 1, the heat exchanger 3 and the water pump unit 4 are arranged on the same side of the water tank 2 in the length direction, and a hot water module with reasonable layout and compact structure is formed. The hot water module can be used as an optional accessory of a heating and ventilation device, and can be installed, transported, moved, etc. independently of an outdoor main machine. Users can individually select and match the hot water module according to actual needs. In addition, the volume of the water tank 2 is usually larger than that of the heat exchanger 3 and the water pump unit 4, and the water tank 2 is placed horizontally, so that the hot water module can be placed in a bay window position in a residence, the bay window space is fully utilized, and the hot water module can be better applied to the installation requirements in a family residence.

[0030] As shown in Figures 1 to 4 some embodiments, the shell 1 includes side panels and a bottom plate 14 connected together, and a top cover plate 13 arranged in parallel and spaced apart from the bottom plate 14. The side panels include two long side panels 11 arranged in opposite directions and two short side panels 12 arranged in opposite directions. In the state that the hot water module is naturally placed on the ground, the bottom plate 14 is in contact with the ground, the bottom plate 14 and the top cover plate 13 are parallel to the ground, the long side panels 11 and the short side panels 12 are perpendicular to the ground, and the long side panels 11 and the short side panels 12 are perpendicular to each other. The maximum length of the long side panel 11 is greater than the maximum length of the short side panel 12. The top cover plate 13, the bottom plate 14, the long side panel 11 and the short side panel 12 together enclose a cuboid cavity. Any two adjacent ones of the top cover plate 13, the bottom plate 14, the long side panel 11 and the short side panel 12 can be independent and detachable components, or can be an integral structure. For example Figure 3 As shown in some embodiments, the bottom plate 14 and one of the short side panels 12 are an integral structure. The water tank 2 has two ends in the length direction, and the two ends are respectively directed to the two short side panels 12.

[0031] In some embodiments, the hot water module further includes at least one of a first connecting piece 81, a second connecting piece 82 and a third connecting piece 83. That is, in different embodiments, the first connecting piece 81, the second connecting piece 82 and the third connecting piece 83 can be selected one by one, two by two or all. As shown in Figure 2 , Figure 4 , Figure 7 and Figure 8 The first connecting piece 81 is arranged between the water tank 2 and the bottom plate 14, and is used for connecting the water tank 2 and the bottom plate 14; that is, the first connecting piece 81 can be used to support the water tank 2 and fix the water tank 2 on the bottom plate 14. As shown in Figures 4 to 7As shown, the second connecting member 82 is arranged between the heat exchanger 3 and the bottom plate 14, and is used to connect the heat exchanger 3 and the bottom plate 14; that is, the second connecting member 82 can be used to reinforce the heat exchanger 3, and fix the heat exchanger 3 on the bottom plate 14; or, the second connecting member 82 can also be arranged between the heat exchanger 3 and the side plate, and is used to connect the heat exchanger 3 and the side plate; that is, the second connecting member 82 can be used to fix the heat exchanger 3 on the side plate. As Figures 2 to 6 As shown, the third connecting member 83 is arranged between the water pump unit 4 and the bottom plate 14, and is used to connect the water pump unit 4 and the bottom plate 14; that is, the third connecting member 83 can be used to reinforce the water pump unit 4, and fix the water pump unit 4 on the bottom plate 14.

[0032] In some embodiments, the water pump unit 4 includes a first water pump 41 and a second water pump 42. Of course, in other embodiments, the water pump unit 4 can also include one or more than two water pumps. In some embodiments, the first water pump 41 can be a circulating water pump, and the second water pump 42 can be a zero-cold water pump. When the water pump unit 4 includes only one water pump, the water pump is a circulating water pump.

[0033] As Figure 8 As shown, in some embodiments, the third connecting member 83 includes two support surfaces with different heights. Each support surface is parallel to the bottom plate 14. The first water pump 41 and the second water pump 42 are arranged on the two support surfaces, respectively. For example Figure 8 In the embodiment shown, the third connecting member 83 includes a first support surface 831 and a second support surface 832, the first support surface 831 is arranged at a higher height than the second support surface 832, the first water pump 41 is arranged on the first support surface 831, and the second water pump 42 is arranged on the second support surface 832. Therefore, the first water pump 41 and the second water pump 42 can be arranged at different height positions, fully utilizing the space in the height direction of the cavity, so that the structure of the water pump unit 4 in the horizontal direction is more compact. Specifically, the third connecting member 83 is formed into a stepped structure by bending a long strip-shaped plate member multiple times, and the two ends of the third connecting member 83 in the length direction are connected to the bottom plate 14, respectively.

[0034] As Figure 8 As shown, in some embodiments, the number of the first connecting members 81 is two, and the two first connecting members 81 are arranged on the bottom plate 14 in a spaced manner. The water tank 2 is supported on the two first connecting members 81 simultaneously.

[0035] As Figure 4As shown, in some embodiments, there are two second connectors 82, which are spaced apart on the heat exchanger 3. Each second connector 82 has a first bolt hole, and the short side panel 12 has a second bolt hole aligned with the first bolt hole. By passing a bolt through the second bolt hole on the short side panel 12 and the first bolt hole on the second connector 82, the heat exchanger 3 can be fixed to the short side panel 12.

[0036] like Figure 4 As shown, in some embodiments, the heat exchanger 3 is disposed on one side of the water pump unit 4 along a direction perpendicular to the long side panel 11. That is, along the direction perpendicular to the long side panel 11, the heat exchanger 3 and the water pump unit 4 are disposed on opposite sides. Along the direction perpendicular to the short side panel 12, the water tank 2, the heat exchanger 3, and the water pump unit 4 are disposed on opposite sides. In this way, the layout of the water tank 2, the heat exchanger 3, and the water pump unit 4 within the cavity is compact and reasonable, and the phenomenon of pipe bends is not easily caused.

[0037] In some embodiments, the hot water module further includes a piping assembly connected to at least one of the water tank 2, heat exchanger 3, and water pump unit 4. That is, the piping assembly includes multiple pipes connected to at least one of the water tank 2, heat exchanger 3, and water pump unit 4, or connected between any two or three of the water tank 2, heat exchanger 3, and water pump unit 4. For example, Figures 4 to 7 As shown, in some embodiments, the piping assembly is at least partially located on the side of the heat exchanger 3 away from the water pump unit 4. That is, the piping assembly can be partially or entirely located on the side of the heat exchanger 3 away from the water pump unit 4. Furthermore, when the piping assembly is partially located on the side of the heat exchanger 3 away from the water pump unit 4, the pipe length of the piping assembly on the side of the heat exchanger 3 away from the water pump unit 4 can be greater than the pipe length of the remaining portion of the piping assembly. In other words, the piping assembly includes a first part and a second part, the first part being located on the side of the heat exchanger 3 away from the water pump unit 4, and the pipe length of the first part being greater than the pipe length of the second part. Thus, the piping assembly is mostly concentrated on the side of the heat exchanger 3 away from the water pump unit 4, making the horizontal layout of the piping assembly within the cavity compact and concentrated, reducing the likelihood of pipe bends.

[0038] For further information, please refer to [link / reference]. Figures 4 to 7In some embodiments, the pipe assembly is at least partially arranged on the side of the heat exchanger 3 away from the bottom plate 14 (i.e. above the heat exchanger 3). That is, the pipe assembly can be partially or entirely arranged on the side of the heat exchanger 3 away from the bottom plate 14. Moreover, when the pipe assembly is partially arranged on the side of the heat exchanger 3 away from the bottom plate 14, the length of the pipe on the side of the heat exchanger 3 away from the bottom plate 14 (i.e. above the heat exchanger 3) can be greater than the length of the pipe of the rest of the pipe assembly. That is, the pipe assembly comprises a third portion and a fourth portion, the third portion is arranged on the side of the heat exchanger 3 away from the bottom plate 14, and the length of the pipe of the third portion is greater than the length of the pipe of the fourth portion. In this way, the pipe assembly is mainly arranged on the side of the heat exchanger 3 away from the bottom plate 14, so that the layout of the pipe assembly in the height direction of the cavity is compact and concentrated, and the phenomenon of pipe winding is less likely to occur.

[0039] When the length of the pipe on the side of the heat exchanger 3 away from the water pump unit 4 is greater than the length of the pipe of the rest of the pipe assembly, and the length of the pipe on the side of the heat exchanger 3 away from the bottom plate 14 (i.e. above the heat exchanger 3) is greater than the length of the pipe of the rest of the pipe assembly, the pipe assembly is arranged on the side of the heat exchanger 3 away from the water pump unit 4 and on the side of the heat exchanger 3 away from the bottom plate 14, and the layout of the pipe assembly is the most compact and reasonable, and the phenomenon of pipe winding is less likely to occur.

[0040] As shown in FIG. 1, Figures 2 to 8 In some embodiments, the hot water module further comprises an electric control box 5 arranged in the cavity. The electric control box 5, the heat exchanger 3 and the water pump unit 4 are located on the same side of the water tank 2 in the length direction of the water tank 2, and the electric control box 5 is located on the side of the heat exchanger 3 away from the bottom plate 14. In the drawings, Figures 2 to 4 as a reference, the electric control box 5, the heat exchanger 3 and the water pump unit 4 are located on the right side of the water tank 2, and the electric control box 5 is located above the heat exchanger 3. That is, the electric control box 5 is farther away from the ground relative to the heat exchanger 3. Alternatively, in other embodiments, the electric control box 5 can be further located on the side of the water pump unit 4 away from the bottom plate 14, that is, the electric control box 5 is located above the water pump unit 4, and the electric control box 5 is farther away from the ground relative to the water pump unit 4. As shown in FIG. 1, Figure 2 Figure 3 and Figure 7 ​As shown in the drawings, in some embodiments, one of the short side panels 12 of the housing 1 is provided with a first access opening near the heat exchanger 3, the water pump unit 4 and the electric control box 5, and a first cover plate 61 is provided on the first access opening. The first cover plate 61 is detachably or rotatably connected to the short side panel 12. After the first cover plate 61 is moved by a person, the internal electrical elements, wiring terminals and the like of the electric control box 5 are exposed through the first access opening, which can be used for maintenance by the person. Since the electric control box 5 is farther away from the side of the ground relative to the heat exchanger 3 and the water pump unit 4, and the short side panel 12 near the electric control box 5 is provided with the first access opening, the position of the electric control box 5 is very convenient for maintenance.

[0041] Similarly, as shown in the drawings, Figure 1 In some embodiments, one of the short side panels 12 of the housing 1 is provided with a second access opening near the water tank 2, and a second cover plate 62 is provided on the second access opening. The second cover plate 62 is detachably or rotatably connected to the short side panel 12. After the second cover plate 62 is moved by a person, the end surface of the water tank 2 away from the heat exchanger 3 and the water pump unit 4 is exposed through the second access opening, which can be used for maintenance of the water tank 2 by the person.

[0042] The pipeline assembly includes a heat exchanger pipeline and a water pump pipeline. The heat exchanger pipeline is connected to the heat exchanger 3, and the water pump pipeline is connected to the water pump unit 4. Specifically, as shown in the drawings, Figures 2 to 7 The heat exchanger pipeline includes a refrigerant input pipe 71, a refrigerant output pipe 72, a heat exchanger water inlet pipe 73 and a heat exchanger water outlet pipe 74. The water pump pipeline includes a water pump water inlet pipe 75 and a water pump water outlet pipe 76. The pipeline assembly further includes a water tank water inlet pipe 77 and a water tank water outlet pipe 78. The water tank water inlet pipe 77 is connected to the water tank 2 at one end and is used to connect to a cold water source at the other end. The water tank water outlet pipe 78 is connected to the water tank 2 at one end and is used to connect to a water end (such as a shower, faucet, etc.) at the other end. Taking the second water pump 42 as an example, the water pump water inlet pipe 75 can be used to connect the pipeline of the water end. The water pump water outlet pipe 76 is connected to the water tank 2, or the water pump water outlet pipe 76 can be connected to the same tap water inlet pipe as the water tank 2. The cold water in the pipeline of the water end is sent to the hot water module for reheating through the water pump water inlet pipe 75. The refrigerant input pipe 71 and the refrigerant output pipe 72 are respectively connected to the heat exchanger 3 at one end and are used to connect to a host computer at the other end. The heat exchanger water inlet pipe 73 and the heat exchanger water outlet pipe 74 are respectively connected to the heat exchanger 3 at one end and are connected to the water tank 2 at the other end. The first water pump 41 is connected to the heat exchanger water inlet pipe 73.

[0043] The principle of the corresponding hot water module preparing hot water is roughly as follows: the external high-temperature refrigerant provided by the outdoor main machine enters the heat exchanger 3 through the refrigerant input pipe 71, the cold water of the water tank 2 is driven by the circulating water pump to enter the heat exchanger 3 through the heat exchanger water inlet pipe 73, the cold water is heated in the heat exchanger 3 by heat exchange with the high-temperature refrigerant, the heated hot water comes out of the heat exchanger water outlet pipe 74 and returns to the water tank 2, and the cooled refrigerant returns to the outdoor main machine through the refrigerant output pipe 72.

[0044] As shown in Figures 2 to 7 some embodiments, the heat exchanger pipe is at least partially located on the side of the heat exchanger 3 away from the water pump unit 4, so that the heat exchanger pipe and the water pump unit 4 are arranged away from each other, and a space is left between the heat exchanger pipe and the water pump unit 4 for placing the electric control box 5. As shown in Figure 5 and Figure 6 , the electric control box 5 is located between the heat exchanger pipe and the water pump unit 4. Specifically, the electric control box 5 is located between the heat exchanger pipe as a whole and the water pump unit 4 as a whole, and the projection of the electric control box 5 in the vertical direction and the projection of the heat exchanger pipe in the vertical direction can partially overlap or completely not overlap; similarly, the projection of the electric control box 5 in the vertical direction and the projection of the water pump unit 4 in the vertical direction can partially overlap or completely not overlap. The vertical direction is perpendicular to the ground surface of the hot water module.

[0045] Further, as shown in Figures 4 to 6 , the water inlet 43 and the water outlet 44 of the water pump unit 4 are collectively referred to as inlet and outlet ports. The inlet and outlet ports of the water pump unit 4 are away from one side of the heat exchanger 3, so that the heat exchanger pipe and the inlet and outlet ports of the water pump unit 4 are arranged away from each other, and the part of the pipe connected with the inlet and outlet ports of the water pump unit 4 is also correspondingly away from one side of the heat exchanger 3. In this way, a space can be left between the heat exchanger pipe and the inlet and outlet ports of the water pump unit 4 for placing the electric control box 5. Therefore, the electric control box 5 can be located between the heat exchanger pipe and the inlet and outlet ports of the water pump unit 4. In this way, the space on the side away from the water tank 2 in the cavity can be fully utilized to place the electric control box 5, while avoiding physical position interference between the electric control box 5 and the pipe assembly.

[0046] Further, as shown in Figure 2 , in some embodiments, the heat exchanger 3, the water pump unit 4 and the electric control box 5 are located between the end of the water tank 2 away from the second access hole and the short side side panel 12 on which the first access hole is located. As shown in Figure 2 , the distance between the left short side side panel 12 and the water tank 2 is much smaller than the distance between the right short side side panel 12 and the water tank 2, so that one of the short side side panels 12 is relatively closer to the water tank 2, and the other short side side panel 12 is relatively farther away from the water tank 2. The electric control box 5 is connected with the short side side panel 12 away from the water tank 2.

[0047] 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.
