DETAILED DESCRIPTION

[0034] In the description of the embodiments of the present application, it should be noted that the terms "first direction", "second direction" and "third direction" are based on the attached Figure 5 , Attachment Figure 6 , Attachment Figure 7 These directional terms are only used to facilitate the description of the embodiments of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0035] The present application embodiment provides a heat pump system. Figure 1 , the heat pump system includes a hydraulic module 1000 .

[0036] Heat pump systems include but are not limited to heat pump water heaters, heat pump air conditioners, heat pump floor heating, heat pump multi-generation (such as air conditioning and floor heating dual-generation, air conditioning and floor heating hot water trigeneration), etc.

[0037] The heat pump system is provided with a water circulation pipeline. The main function of the hydraulic module 1000 is to exchange heat with the water from the water circulation pipeline to obtain hot water or cooling water. The water after heat exchange is then transported through the water circulation pipeline to the water storage device such as the water tank of the heat pump system or the terminal such as the fan coil, floor heating pipe, radiator, etc.

[0038] See also Figures 1 to 4 An electric control box 100 is disposed inside the hydraulic module 1000 , and the electric control box 100 is connected to other components in the hydraulic module 1000 through various cables.

[0039] See also Figure 5 , Figure 6 and Figure 7 The electric control box 100 of the embodiment of the present application includes a box body 10, an electric control board assembly 20 and a wire fixing assembly 30.

[0040] The box body 10 includes a bottom plate 11 and a side panel 12 having a wire opening 12a. The bottom plate 11 and the side panel 12 surround a receiving cavity 10a having an opening 10b. The opening 10b and the bottom plate 11 are respectively located on opposite sides of the side panel 12 along a first direction.

[0041] The electric control board assembly 20 and the wire fixing assembly 30 are both arranged in the accommodating cavity 10a, and the wire fixing assembly 30 is arranged on one side of the electric control board assembly 20, wherein the wire fixing assembly 30 includes a first wire fixing structure 31 and a second wire fixing structure 32, the first wire fixing structure 31 and the second wire fixing structure 32 are stacked and arranged at intervals along a first direction, and the first wire fixing structure 31 is located on the side of the second wire fixing structure 32 away from the bottom plate 11.

[0042] Specifically, the opening 10b is used to place or take out components such as the electric control board assembly 20 installed in the accommodating cavity 10a, and can also be used to arrange cables in the accommodating cavity 10a.

[0043] For example, see Figures 1 to 4 The electric control box 100 may be provided with a box cover 90, and the box cover 90 is disposed on the box body 10 to close the opening 10b.

[0044] The first wire fixing structure 31 and the second wire fixing structure 32 are used to restrain different cables, which may be different types of cables such as strong current cables and weak current cables, or at least two cables of the same type. The wire passing opening 12a is used to pass cables.

[0045] The number of the wire passing openings 12a may be one or more. Preferably, multiple wire passing openings 12a may be provided, and different cables are respectively passed through corresponding wire passing openings 12a, so that different cables are separated at the wire passing openings 12a.

[0046] The first wire fixing structure 31 and the second wire fixing structure 32 are arranged in a spaced-apart manner along the first direction, which means that the first wire fixing structure 31 and the second wire fixing structure 32 are arranged in a spaced-apart manner along the first direction, and at the same time, on a projection plane perpendicular to the first direction, the projection of the arrangement area of ​​the first wire fixing structure 31 and the projection of the arrangement area of ​​the second wire fixing structure 32 at least partially overlap. The projection of the arrangement area of ​​the first wire fixing structure 31 and the arrangement area of ​​the second wire fixing structure 32 refer to the maximum area required for arranging the first wire fixing structure 31 or the second wire fixing structure 32.

[0047] For example, see Figures 5 to 7 , wherein a part of the cables can be constrained by the first wire fixing structure 31, which is equivalent to the routing path of a part of the cables passing through the first wire fixing structure 31 and the wire passing port 12a, wherein another part of the cables can be constrained by the second wire fixing structure 32, which is equivalent to the routing path of the other part of the cables passing through the second wire fixing structure 32.

[0048] That is to say, by providing the first wire fixing structure 31 and the second wire fixing structure 32, and the first wire fixing structure 31 and the second wire fixing structure 32 are stacked at intervals along the first direction, at least two different wiring paths can be formed inside the electric control box 100, and different cables can be routed separately, the routing is more regular, and different cables are not easy to touch each other and cause interference. At the same time, the first direction is equivalent to the thickness direction of the electric control box 100, and there is generally a certain amount of free space in the thickness direction of the electric control box 100. Therefore, by stacking the first wire fixing structure 31 and the second wire fixing structure 32 at intervals along the first direction, the space in the thickness direction of the electric control box 100 can be fully utilized to arrange the first wire fixing structure 31 and the second wire fixing structure 32, which is conducive to the compact design of the accommodating cavity 10a, and then the overall structure of the electric control box 100 can be relatively compact, and the manufacturing cost is lower.

[0049] In one embodiment, please refer to Figure 4 and Figure 5 , the wire port 12a can be located on one side of the electric control board assembly 20 along the second direction, and the wire fixing assembly 30 can be located on one side of the electric control board assembly 20 along the third direction, wherein the second direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction and the first direction, respectively. That is, the cables respectively constrained by the first wire fixing structure 31 and the second wire fixing structure 32 need to extend at least along the third direction.

[0050] See also Figure 4 and Figure 5 The wire-passing opening 12a may be located on one side of the side panel 12 along the third direction close to the wire-fixing assembly 30 to minimize the distance between the wire-passing opening 12a and the wire-fixing assembly 30 and improve the convenience of cable routing.

[0051] See also Figure 6 and Figure 7 The first wire fixing structure 31 may include a first wire passing seat 311 disposed on the side panel 12, the first wire passing seat 311 having a first wire passing groove 311a and two first wire openings 311b connected to the first wire passing groove 311a, the two first wire openings 311b being respectively located at opposite sides of the first wire passing groove 311a along the second direction. The cables may respectively pass into or pass out of the first wire passing groove 311a from the two first wire openings 311b to achieve extension along the third direction.

[0052] See also Figure 7 A first slot 311c connected to the first slot 311a can be provided on the side of the first cable holder 311 facing away from the bottom plate 11, and the cable can enter the first cable slot 311a from the first slot 311c. The first slot 311c is located at the opening 10b, which not only makes it convenient for the operator to put the cable into the first cable slot 311a, but also after the electric control box 100 is covered with the box cover 90, the box cover 90 can also block the first slot 311c while closing the opening 10b, so as to better prevent the cable from escaping from the first slot 311c to the outside of the first cable slot 311a.

[0053] See also Figure 5 and Figure 7 , the first wire fixing structure 31 can also be provided with a plurality of first routing buckles 312, and the plurality of first routing buckles 312 are arranged at intervals along the second direction on the side of the first wire passing seat 311 away from the side panel 12. Some cables can extend partially along the second direction by continuously passing through the plurality of first routing buckles 312, and at the same time be limited by the first routing buckles 312 on the side of the first wire passing seat 311 away from the side panel 12, while some cables can respectively pass through or pass through the first wire passing groove 311a from the two first wire openings 311b to extend along the second direction under the limitation of the first wire passing seat 311. It can be seen that the first wire fixing structure 31, by providing the first wire fixing structure 31 and the second wire fixing structure 32, enables the cables to form two different routing paths at the first wire fixing structure 31, respectively, and multiple cables can be routed separately, the routing is more regular, and different cables are not easy to touch each other and cause interference.

[0054] In other embodiments, the first wire fixing structure 31 may have only the first wire passing seat 311 without the multiple first wiring buckles 312, or may have only the multiple first wiring buckles 312 without the first wire passing seat 311. In addition, the first wire fixing structure 31 may also adopt other structural forms as long as it can restrain the cables.

[0055] See also Figure 6The second wire fixing structure 32 may be provided with a plurality of second wiring buckles 321 , and the plurality of second wiring buckles 321 are spaced apart along the second direction. The cable may be constrained by the plurality of second wiring buckles 321 and extend at least along the second direction.

[0056] It should be noted that the second wire fixing structure 32 is not limited to the configuration of multiple second routing buckles 321. According to specific design requirements, the second wire fixing structure 32 can also adopt other structural forms such as a wire seat as long as the cables can be restrained.

[0057] In one embodiment, please refer to Figure 5 The electric control panel assembly 20 includes a main control panel (not shown in the figure) having a weak current wiring area and a strong current wiring area. The weak current wiring area is located on the side of the strong current wiring area away from the wire fixing assembly 30 along the third direction. The electric control box 100 can be provided with a third wire fixing structure 60. The third wire fixing structure 60 is located on the side of the electric control panel assembly 20 away from the wire passing port 12a along the second direction, and is stacked at intervals on the side of the main control panel close to the opening 10b.

[0058] Specifically, the weak current wiring area is used to connect weak current cables, which can be constrained by the first fixed line structure 31 and the third fixed line structure 60 , and the strong current wiring area is used to connect strong current cables, which can be constrained by the second fixed line structure 32 .

[0059] The third wire fixing structure 60 is stacked at intervals on one side of the main control board close to the opening 10b, which means that the third wire fixing structure 60 is located on the side of the main control board close to the opening 10b, and the third wire fixing structure 60 is spaced apart from the main control board. At the same time, on the projection plane perpendicular to the first direction, the projection of the setting area of ​​the third wire fixing structure 60 (that is, the maximum area required for setting the third wire fixing structure 60) at least partially overlaps with the projection of the electric control board assembly 20.

[0060] This arrangement can not only fully utilize the space in the thickness direction of the electric control box 100 to arrange the third wire fixing structure 60, but also play a pulling effect on the weak-current cables to avoid the weak-current cables from touching the main control board as much as possible.

[0061] For example, see Figure 5 and Figure 6 The third wire fixing structure 60 may include a second wire passing seat 61 disposed on the side panel 12, the second wire passing seat 61 having a second wire passing groove 61a and two second wire openings 61b connected to the second wire passing groove 61a, the two second wire openings 61b being respectively located at opposite sides of the second wire passing groove 61a along the third direction. The weak current cable may respectively pass into or pass out of the second wire passing groove 61a from the two second wire openings 61b, so as to extend in a more regular manner along the third direction under the limitation of the second wire passing seat 61.

[0062] For further information, see Figure 5 and Figure 7 A second slot 61c connected to the second cable trough 61a can be provided on the side of the second cable holder 61 facing away from the bottom plate 11, and the weak-current cable can enter the second cable trough 61a from the second slot 61c. The second slot 61c is located at the opening 10b, which not only makes it convenient for the operator to put the weak-current cable into the second cable trough 61a, but also after the electric control box 100 is covered with the box cover 90, the box cover 90 can also close the opening 10b while blocking the first slot 311c to better prevent the weak-current cable from escaping from the second slot 61c to the outside of the second cable trough 61a.

[0063] In one embodiment, please refer to Figure 7 The third wire fixing structure 60 can be provided with a plurality of second wire passing seats 61, and the plurality of second wire passing seats 61 are arranged at intervals along the third direction to form component avoidance spaces 60a at the intervals. The component avoidance spaces 60a can not only be used to avoid various electronic components on the main control board, but also provide more routing paths for cables to access the weak current wiring area.

[0064] In one embodiment, please refer to Figure 6 and Figure 7 The electric control box 100 includes a power connection socket 40 disposed in the accommodating cavity 10 a. The power connection socket 40 is disposed on one side of the electric control board assembly 20 close to the wire opening 12 a along the second direction and close to the wire fixing assembly 30 .

[0065] The power terminal socket 40 is used to connect two power lines, wherein one of the two power lines is connected to the high-voltage wiring area of ​​the main control board and the power terminal socket 40 respectively, and the other power line enters the accommodating cavity 10a from the outside of the electric control box 100 and is connected to the power terminal socket 40.

[0066] For example, see Figure 7 At least one external wiring port 10c may be provided on the side panel 12, and another power line may enter the accommodating cavity 10a from the external wiring port 10c.

[0067] Exemplarily, the power lines respectively connected to the high-voltage wiring area of ​​the main control board and the power terminal holder 40 can be constrained by the second wire fixing structure 32. At the same time, since the power terminal holder 40 is arranged on the side of the electric control board assembly 20 close to the wire port 12a along the second direction and close to the wire fixing assembly 30, the length of this power line can also be set relatively short, and the wiring is simpler.

[0068] For further information, see Figure 6The electric control box 100 can also be provided with a wire crimping clamp 50, which is arranged on the same side of the electric control board assembly 20 as the power terminal socket 40, and the wire crimping clamp 50 is located on the side of the power terminal socket 40 away from the wire fixing assembly 30 along the third direction. The power line that enters the accommodating cavity 10a from the outside of the electric control box 100 and is connected to the power terminal socket 40 can be constrained by the wire crimping clamp 50 to prevent poor contact caused by shaking of the power line.

[0069] In one embodiment, please refer to Figure 7 The electric control box 100 may also be provided with a signal line terminal block 70 , and the signal line terminal block 70 is arranged on one side of the electric control board assembly 20 close to the wire port 12 a along the second direction and close to the wire fixing assembly 30 .

[0070] The signal line terminal block 70 is used to connect two signal lines, wherein one of the two signal lines is connected to the weak current wiring area of ​​the main control board and the signal line terminal block 70 respectively, and the other signal line enters the accommodating cavity 10a from the outside of the electric control box 100 and is connected to the signal line terminal block 70.

[0071] For example, see Figure 7 , another signal line can also enter the accommodating cavity 10a from the external wiring port 10c.

[0072] Exemplarily, the signal lines respectively connected to the weak-current wiring area of ​​the main control board and the signal line terminal block 70 can be constrained by the first fixed line structure 31 and the third fixed line structure 60. At the same time, since the signal line terminal block 70 is arranged on the side of the electrical control board assembly 20 close to the wire port 12a along the second direction and close to the fixed line assembly 30, the length of this signal line can also be set to be relatively short, and the wiring is simpler.

[0073] In addition, when the signal line is constrained by the first fixed line structure 31 and the power line is constrained by the second fixed line structure 32, the signal line and the power line can be separated, effectively preventing the power line with higher current intensity from interfering with the signal line with lower current intensity, thereby avoiding signal interference to a certain extent.

[0074] In one embodiment, please refer to Figures 1 to 3 The electric control box 100 includes two mounting plates 80 with first fastening holes 80a, the box cover 90 includes a cover body 91 and two connecting edges 92 with second fastening holes 92a, the opposite sides of the cover body 91 respectively have flanges 93 folded toward the same side of the cover body 91, the connecting edges 92 are connected to the flanges 93 in a one-to-one correspondence, the two mounting plates 80 are arranged on the outer surfaces of the opposite sides of the side panel 12, the cover body 91 is covered at the opening 10b, each flange 93 faces the outer surface of the side panel 12, and the second fastening holes 92a are connected to the first fastening holes 80a in a one-to-one correspondence.

[0075] The second fastening holes 92a and the first fastening holes 80a that are connected one by one are provided with fasteners such as screws and bolts, so that the box cover 90 can be fastened to the mounting plate 80. The box cover 90 is provided with flanges 93 on opposite sides of the cover body 91, so that a structure similar to a slide groove can be formed between the two flanges 93. Therefore, during the installation of the box cover 90, the box cover 90 can be slid on the box body 10 to connect the second fastening holes 92a with the first fastening holes 80a, thereby improving the convenience of installing the box cover 90.
