[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0053] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0055] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0056] Residential heat pump systems integrate water and refrigerant systems, enabling them to produce both hot and cold water to meet diverse customer needs. For example, a typical heat pump system uses a combined top-floor and bottom-floor water system. Through heat exchange between refrigerant and water, the system generates either hot or cold water within the heat pump unit, which is then piped to indoor terminals (such as fan coil units) or underfloor heating. In summer, the cold water circulates to lower the indoor temperature; in winter, the hot water is supplied through the underfloor heating coils. Because the heat pump unit is outdoors, and the refrigerant only circulates within the unit and does not enter the room, the use of cold or hot water for heat transfer effectively avoids refrigerant poisoning caused by leaks, making top-floor and bottom-floor water systems safer. However, heat pump installation requires external connections to fan coil units, underfloor heating, etc., necessitating wiring. Due to the limited installation space in residential environments, the compact structure of heat pump units increases wiring difficulty and reduces installation efficiency.

[0057] To address the aforementioned technical problems, this utility model provides an electrical control box assembly that facilitates wiring by operators. The electrical control box assembly of this utility model embodiment is described below with reference to the accompanying drawings.

[0058] Reference Figure 1 , Figure 2 and Figure 3 As shown, the electrical control box assembly 260 of one embodiment of this utility model can be applied to a heat pump device 1000. The heat pump device can be a water heater, generally used to connect to HVAC terminals such as fan coil units and underfloor heating. The water heater and HVAC terminals can be configured as a skywater / groundwater system or a sky-fluorinated / groundwater system, etc. The water heater includes a housing 100, a circuit module 200, a fan 300, a refrigerant circuit module 400, a water circuit module 500, and a compressor 600.

[0059] The heat pump device 1000 of this utility model embodiment can also be the outdoor unit of an air conditioner. The outdoor unit of the air conditioner includes a housing 100, a circuit module 200, a fan 300, a refrigerant circuit module 400, and a compressor 600. The outdoor unit of the air conditioner does not have a water circuit module 500.

[0060] The electrical control box assembly 260 in this embodiment includes a circuit board and a protective cover 230. For example, the circuit board may be a water circuit wiring board 210 or a main control board 250, etc. For ease of description, all subsequent embodiments will be explained using the water circuit wiring board 210 as an example.

[0061] In the heat pump device 1000 of this embodiment, the water circuit connection board 210 is provided with a connection point 211, which is located at the edge of the water circuit connection board 210. A protective cover 230 is installed on the side of the water circuit connection board 210 with the connection point 211. The protective cover 230 can effectively protect various electronic components on the water circuit connection board 210, such as capacitors, resistors, control chips, etc. (Refer to...) Figure 4 , Figure 5 and Figure 6 As shown, the protective cover 230 has a notch 231 for exposing at least a portion of the wiring position 211, for example, the notch 231 for exposing all of the wiring position 211. The protective cover 230 includes a flip-up portion 232, which is rotatably connected to the notch 231 and can be flipped outwards from the protective cover 230. The flip-up portion 232 has a closed state and an open state. When the flip-up portion 232 is in the closed state, it can cover the wiring position 211. When the flip-up portion 232 is in the open state, it can open the notch 231, so that the wiring position 211 is exposed from the protective cover 230.

[0062] Using the above solution, when wiring is required on the water circuit terminal block 210, the flip-up part 232 is rotated to open it, exposing the wiring position 211. Therefore, it is not necessary to disassemble the entire protective cover 230, which facilitates wiring for operators and improves wiring efficiency. After wiring is completed, the flip-up part 232 is closed, making installation convenient and quick. Since the protective cover 230 still covers the water circuit terminal block 210, and the wiring position 211 is only exposed by opening the flip-up part 232, the protective cover 230 still protects the capacitors, resistors, control chips, and other electronic components it covers. This effectively reduces the possibility of wiring tools accidentally touching other electronic components on the water circuit terminal block 210, thereby reducing the probability of misoperation and improving wiring safety.

[0063] Reference Figure 1 and Figure 2As shown, a heat pump device 1000 according to an embodiment of this utility model includes a housing 100, a fan 300, a circuit module 200, a refrigerant circuit module 400, and a water circuit module 500. The housing 100 is generally square, and a fan space 110 and a module space 120 are formed inside the housing 100. The fan space 110 and the module space 120 can be arranged in a left-right direction. The housing 100 is provided with a mounting hole 130, for example, the mounting hole 130 is located on the upper part of the right side wall of the housing 100. The housing 100 includes an electrical control cover plate 140, which is detachably connected to the outside of the mounting hole 130. The fan 300 is installed in the fan space 110. For example, there are two fans 300, which are arranged at intervals in a vertical direction to improve the heat exchange effect. The circuit module 200, the fluorine circuit module 400, and the water circuit module 500 are respectively installed in the module space 120. The circuit module 200 is installed in the module space 120 near the top of the outer shell 100, and the fluorine circuit module 400 and the water circuit module 500 are located on the side of the circuit module 200 away from the top of the outer shell 100.

[0064] Reference Figure 2 As shown, the circuit module 200 includes an electrical control box assembly 260. The water circuit connection board 210 of the electrical control box assembly 260 is located on the side near the electrical control cover 140 and faces the electrical control cover 140. For example, the water circuit connection board 210 is used to control the start / stop and speed of the water pump 700 to regulate water flow and pressure, ensuring that cold or hot water is delivered to the fan coil unit or underfloor heating as needed. The water circuit connection board 210 can also be used to control electric valves in the water circuit, such as three-way valves and two-way valves, switching the water flow path between cooling / heating modes; it can also monitor parameters such as water pressure, water temperature, and flow rate in real time, triggering protection mechanisms. The electrical control cover 140 is configured such that, after removal, the wiring positions 211 of the water circuit connection board 210 are exposed through the mounting holes 130, allowing operators to connect the water circuit connection board 210 through the mounting holes 130.

[0065] Using the above scheme, the fan 300 rotates under the control of the circuit module 200, thereby allowing air to pass through the heat pump device 1000 for heat exchange. The refrigerant (such as Freon) is connected to the refrigerant circuit module 400; water is connected to the water circuit module 500, and the water pump 700 of the water circuit module 500 provides power to the water, facilitating heat exchange between the refrigerant and water through the heat exchanger. This allows the water to be heated to hot water or cooled to cold water. The hot or cold water is then transported to the room through pipes, thereby regulating the indoor temperature. Because the mounting holes 130 of the housing 100 are covered by a removable electrical control cover 140, and the water circuit connection board 210 of the circuit module 200 is located on the side close to and facing the electrical control cover 140, the wiring positions 211 of the water circuit connection board 210 are exposed through the mounting holes 130 after the electrical control cover 140 is removed. This allows operators to easily maintain the water circuit connection board 210 through the mounting holes 130, such as wiring or circuit board inspection. It also facilitates wiring between the heat pump equipment 1000 and HVAC terminals such as fan coil units and underfloor heating, reducing the number of parts that need to be disassembled and improving assembly efficiency. In addition, removing the electrical control cover 140 also makes it easier for operators to maintain the circuit module 200.

[0066] Reference Figure 3 As shown in the embodiment of this utility model, the circuit module 200 further includes a bracket 220, and the water circuit connection plate 210 is fixedly connected to the bracket 220. The fixed connection method can be snap-fit, fastener connection, adhesive, etc., to prevent the water circuit connection plate 210 from loosening, poor contact, or component detachment due to vibration or external force. A protective cover plate 230 is connected to the side of the water circuit connection plate 210 facing the electrical control cover plate 140, and the protective cover plate 230 covers the water circuit connection plate 210. The protective cover plate 230 can block dust, water vapor, insects and other foreign objects from entering, preventing short circuits or corrosion, especially when the heat pump equipment 1000 is exposed to rain and snow. At the same time, during maintenance, assembly and other processes, the protective cover plate 230 can also prevent personnel from accidentally touching or tools from colliding with components, such as sensitive parts like capacitors and relays, from being damaged.

[0067] Reference Figure 3 , Figure 4 and Figure 5As shown in the embodiment of this utility model, the water circuit wiring board 210 is provided with wiring positions 211, which are located at the edge of the water circuit wiring board 210. The protective cover 230 has a notch 231 for exposing at least a portion of the wiring positions 211. Therefore, when wiring is required using the wiring positions 211, after opening the electrical control cover 140, since a portion of the wiring positions 211 is exposed through the notch 231 in the mounting hole 130, it is not necessary to completely disassemble the protective cover 230, which facilitates wiring and eliminates the need for repeated disassembly and reassembly of the protective cover 230, significantly shortening construction time and improving operational convenience. At the same time, it can also reduce the risk of misoperation. The design of the notch 231 limits the operating range to the area within the notch 231, thereby reducing the possibility of accidentally touching other circuit components and improving operational safety.

[0068] Reference Figure 6 , Figure 7 and Figure 8 As shown in the embodiment of this utility model, the protective cover 230 includes a flip-up portion 232, which is rotatably connected to the notch 231 and can flip towards the outside of the protective cover 230. The flip-up portion 232 has a closed state and an open state, for example... Figure 7 As shown, the flip-up part 232 is in a closed state to close the notch 231 and cover the wiring position 211, which can protect the wiring position 211 and effectively reduce interference from dust, rainwater, and insects. For example Figure 8 As shown, the flip-up portion 232 is in the open state, opening the notch 231 to expose the wiring position 211 in the mounting hole 130. Therefore, the flip-up portion 232 only exposes a portion of the structure of the water circuit wiring board 210 (e.g., the wiring position 211), preventing accidental damage to other components and improving operational safety. It is understood that, to achieve the flip-up, the flip-up portion 232 can be connected to the protective cover 230 via a hinge. Alternatively, the protective cover 230 can be made of plastic, and the rotational connection of the flip-up portion 232 can be formed by integrally thinning the outer side of the protective cover 230 along its rotation axis; or the rotational connection of the flip-up portion 232 can be formed by intermittently thinning the outer side of the protective cover 230 along its rotation axis; or the rotational connection of the flip-up portion 232 can be formed by intermittently cutting the protective cover 230 along its rotation axis. Using a plastic protective cover 230 simplifies processing, reduces manufacturing costs, and minimizes assembly steps.

[0069] Reference Figure 5As shown in the embodiment of this utility model, there are two wiring positions 211, each including multiple wiring terminals. One wiring position 211 is located at the lower end of the water circuit wiring plate 210 and extends in the front-to-back direction; the other is located on the front side of the water circuit wiring plate 210 and extends in the vertical direction. There are two flip-up parts 232, which correspond to the positions of the two wiring positions 211 respectively and are located on two adjacent side walls of the protective cover plate 230. The protective cover plate 230 has notches 231 at the corresponding positions of the wiring positions 211, so that both wiring positions 211 can be exposed in the notches 231 or covered by the flip-up parts 232, which can improve the convenience of wiring and the protection.

[0070] To facilitate limiting the position of the flip-up part 232 when it is in the open state, refer to... Figure 9 , Figure 10 and Figure 11 As shown in the embodiment of this utility model, a second latch 233 is provided on the outer side of the flip-up part 232, and a second latch 234 is provided on the outer side of the protective cover 230. When the flip-up part 232 is in the open state, the second latch 233 can engage with the second latch 234, thereby restricting the position of the flip-up part 232 and keeping it in the open state. This facilitates subsequent wiring by operators, reduces the impact of the flip-up part 232 on wiring, and improves the convenience of operation. When wiring is completed, rotating the flip-up part 232 separates the second latch 233 and the second latch 234. It should be noted that the positions of the second latch 234 and the second latch 233 can be interchanged, that is, the second latch 234 is provided on the outer side of the flip-up part 232, and the second latch 233 is provided on the outer side of the protective cover 230. The appropriate solution can be selected according to the actual situation.

[0071] Reference Figure 12 and Figure 13 As shown in the embodiment of this utility model, when there are two flip-up parts 232, a second buckle 233 is provided on the outer side of each of the two flip-up parts 232, and two second fastening positions 234 are provided on the corresponding positions on the outer side of the protective cover plate 230, so that both flip-up parts 232 can be fixed by the engagement of the second buckle 233 and the second fastening positions 234 when opened. It should be noted that, in addition to the snap-fit ​​method, the flip-up parts 232 can also be fixed by magnetic connection or screw connection, and the appropriate solution should be selected according to the actual situation.

[0072] Reference Figure 6As shown in the embodiment of this utility model, a retaining edge 235 is provided on the inner side of the protective cover 230, and the retaining edge 235 extends towards the water circuit connection board 210 to the inner side of the connection position 211. Since tools such as screwdrivers may be used during wiring, in order to prevent the screwdriver from touching the capacitors, resistors, control chips and other components of the water circuit connection board 210, a retaining edge 235 is provided on the inner side of the protective cover 230, and the retaining edge 235 is located on the inner side of the connection position 211, thereby preventing tools such as screwdrivers from penetrating into the inner side of the protective cover 230, effectively improving the safety and reliability of wiring.

[0073] Reference Figure 6 and Figure 8 As shown in the embodiment of this utility model, the flip-up part 232 is provided with a third latch 221, and the bracket 220 includes a circuit board base 222. The circuit board base 222 is provided with a third latch position 236. When the flip-up part 232 is in the closed state, the third latch 221 and the third latch position 236 are engaged. Using this latching method, the flip-up part 232 is easier to assemble and disassemble, requiring no screws and resulting in higher assembly efficiency. Simultaneously, it effectively limits the position of the flip-up part 232 in the closed state, preventing it from shaking and improving the protective effect of the flip-up part 232 on the connection point 211, thus enhancing safety.

[0074] Reference Figure 14 , Figure 15 and Figure 16 As shown in the embodiment of this utility model, the top of the circuit board base 222 is provided with an upwardly extending insertion part 223, and the top of the protective cover 230 is provided with an insertion hole 237. The insertion part 223 is inserted into the insertion hole 237 to determine the relative position of the protective cover 230 and the circuit board base 222, thus playing a positioning role. The circuit board base 222 has first buckles 224 on both sides, and the protective cover 230 has first latches 238 on both sides that correspond to and cooperate with the first buckles 224. The first buckles 224 and the first latches 238 engage to fix the relative position of the protective cover 230 and the circuit board base 222. Therefore, when installing the protective cover 230, the insertion part 223 is first inserted into the insertion hole 237 for positioning, and then the protective cover 230 is pressed under external force, causing the first buckles 224 and the first latches 238 to engage, thereby fixing the position of the protective cover 230. This operation is simple and can improve the installation efficiency of the protective cover 230. It should be noted that the positions of the first buckle 224 and the first latch 238 can be interchanged. For example, the first latch 238 can be set on both sides of the circuit board base 222, and the first buckle 224 corresponding to the first latch 238 can be set on both sides of the protective cover 230. This can also facilitate the engagement of the protective cover 230 and the circuit board base 222. The appropriate method should be selected according to the actual situation.

[0075] Reference Figure 16As shown in the embodiment of this utility model, a guide groove 239 is also provided at the first snap-fit ​​position 238. The guide groove 239 is located between the two notches 231 on the protective cover plate 230. The guide groove 239 extends along the snap-fit ​​direction of the first snap-fit ​​224, for example, the guide groove 239 extends in the left-right direction. Therefore, when the first snap-fit ​​224 snaps in, it is guided by the guide groove 239 to the first snap-fit ​​position 238, thereby smoothly snapping in with the first snap-fit ​​position 238, which can further improve the accuracy of snapping and improve the installation efficiency.

[0076] Reference Figure 17 , Figure 18 and Figure 19 As shown in the embodiment of this utility model, the circuit board base 222 is provided with a cable guide plate 240 arranged opposite to the terminal block 211. The cable guide plate 240 is located outside the terminal block 211 and extends in the same direction as the corresponding terminal block 211. The cable guide plate 240 is provided with a plurality of knockout holes 241 arranged at intervals along the arrangement direction of the terminal block 211. It should be noted that multiple terminals can connect multiple cables. Since the outer plastic insulation needs to be removed when connecting the cable and the terminal block, if the removed insulation is long, it may cause the exposed wires of adjacent cables to connect, resulting in short circuits, inaccurate detection, etc. Therefore, by setting the cable guide plate 240, different cables pass through different knockout holes 241 of the cable guide plate 240. The baffles between the knockout holes 241 effectively prevent the exposed wires from contacting each other, thereby improving the safety and reliability of the wiring. In this embodiment, each knockout hole 241 corresponds to two wiring terminals. Since the two wiring terminals form a group, and each group of wiring terminals controls different control units of different HVAC terminals (such as ball valves, sensors, etc.), the isolation between the knockout holes 241 by the baffles can effectively avoid problems such as short circuits or inaccurate detection between control units.

[0077] Reference Figure 19 As shown in the embodiment of this utility model, the wire guide plate 240 is provided with multiple knockdown plates 242, which are matched with multiple knockdown holes 241. The outer contour of the knockdown plate 242 is spaced apart from the inner wall of the knockdown hole 241, and the knockdown plate 242 is fixedly connected to the inner wall of the knockdown hole 241 by at least one connecting strip 243. For example, the knockdown plate 242 can be fixedly connected to the inner wall of the knockdown hole 241 by one or two connecting strips 243. When it is necessary to use the knockdown hole 241 for wire routing, the corresponding knockdown plate 242 can be unscrewed. The knockdown plate 242 of the knockdown hole 241 that is not used for wire routing can be retained, thereby sealing and cooperating with the protective cover plate 230 to improve the protective effect.

[0078] Reference Figure 19 , Figure 20 and Figure 21As shown, in this embodiment of the present invention, the minimum length of the connecting strip 243 along the circumferential direction of the knockout hole 241 is 'a', satisfying the condition: 1.5mm ≤ a ≤ 2.5mm. For example, the value of a can be 1.5mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.5mm, etc. The minimum thickness of the connecting strip 243 is 'b', satisfying the condition: 0.3mm ≤ b ≤ 0.7mm. For example, the value of b can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, etc. It should be noted that the thickness direction of the connecting strip 243 is perpendicular to the length direction of the connecting strip 243. When a is less than 1.5mm and b is less than 0.3mm, the connection strength of the connecting strip 243 is weak, and it is easy to detach directly due to vibration or other reasons during the transportation of the heat pump equipment 1000. When a is greater than 2.5mm and b is greater than 0.7mm, the connection strength of the connecting strip 243 is strong, and it is difficult for operators to pry off the knockout plate 242, resulting in increased wiring difficulty. Therefore, by reasonably designing the value of 'a' to be in the range of 1.5mm to 2.5mm and the value of 'b' to be in the range of 0.3mm to 0.7mm, it can be ensured that the knock-off plate 242 will not easily come loose, and it can also be easily pried off by the operator, thereby improving assembly efficiency.

[0079] Reference Figure 17 As shown, in this embodiment of the present invention, the circuit board base 222 is provided with a first mounting position 2221 and a second mounting position 2222. The second mounting position 2222 is located inside the first mounting position 2221, and the volume of the water circuit connector 210 installed in the second mounting position 2222 is smaller than the volume of the water circuit connector 210 installed in the first mounting position 2221. It can be understood that the second mounting position 2222 and the first mounting position 2221 are configured as mounting positions on the bottom wall of the circuit board base 222, therefore the area of ​​the second mounting position 2222 is smaller than the area of ​​the first mounting position 2221. Therefore, the circuit board base 222 can accommodate both large and small water circuit connectors 210, meeting the installation requirements of different models and improving the versatility of the circuit board base 222. For example, the small water circuit connector 210 installed in the second mounting position 2222 is suitable for low-load scenarios, such as small apartments or single-area control, reducing equipment redundancy costs. The large water circuit connector 210 installed at the first installation position 2221 can meet high power requirements, such as whole-house heating in villas or commercial venues, ensuring heat exchange efficiency and system stability.

[0080] Reference Figure 3As shown in the embodiment of this utility model, the circuit module 200 further includes a main control board 250, and the bracket 220 includes a motherboard base 225 for mounting the main control board 250 and a circuit board base 222 for mounting the water circuit connector 210. The motherboard base 225 and the circuit board base 222 are arranged at intervals along the direction away from the fan space 110. Both the main control board 250 and the water circuit connector 210 are heat-generating components. The interval arrangement can improve the superposition of heat between the two in a limited space, reduce the risk of local high temperature, avoid the accelerated aging of components such as capacitors and relays due to high temperature, and improve system reliability. At the same time, the high-voltage lines and low-voltage signal lines can be routed along the motherboard base 225 and the circuit board base 222 respectively, reducing cross interference. The main control board 250 and the water circuit connector 210 are installed independently, and the circuit module 200 does not need to be completely disassembled during maintenance or upgrades, reducing operational complexity. In some embodiments, some of the piping of the refrigerant module 400 is arranged in the space between the main board base 225 and the circuit board base 222, making the overall structure of the heat pump device 1000 more compact and facilitating the miniaturization of the heat pump device 1000.

[0081] Reference Figure 2 As shown in the embodiment of this utility model, the heat pump device 1000 further includes a compressor 600, a water circuit module 500 located near the bottom of the outer casing 100, a refrigerant circuit module 400 and a compressor 600 installed between the circuit module 200 and the water circuit module 500, with the water circuit module 500 located at the bottom of the module space 120. Because the compressor 600 is centrally mounted and connected to the outer casing 100 via an elastic shock-absorbing pad, it helps absorb the vibration energy of the compressor 600 during operation, reducing resonance noise transmitted to the outer casing 100. Furthermore, the compressor 600's weight is centrally located, forming a symmetrical layout with the bottom water circuit module 500, reducing the risk of device tilting. Since the water circuit module 500 is located at the bottom, if leakage occurs, the water naturally flows downwards and drains from the bottom drain hole, preventing the upper circuit module 200 or refrigerant circuit module 400 from being soaked, reducing the risk of short circuits or corrosion.

[0082] Reference Figure 1 and Figure 2As shown in the embodiment of this utility model, the heat pump device 1000 also includes a chassis 150 and a partition plate 160. The partition plate 160 is fixedly connected to the chassis 150 and separates the fan space 110 and the module space 120, thereby reducing the impact of airflow on the circuit module 200, the refrigerant circuit module 400 and the water circuit module 500. The outer casing 100 also includes a top cover 101, a left front side panel 102, a right front side panel 103, a right rear side panel 104, and a maintenance plate 105. The top cover 101 is connected to the top of the middle partition 160, the left front side panel 102 is connected to the front side of the fan space 110, the right front side panel 103 is connected to the front side of the module space 120, and the right rear side panel 104 is connected to the right side of the module space 120. The mounting hole 130 is opened on the top of the right rear side panel 104, and the bottom of the right rear side panel 104 is provided with a maintenance hole 106. The maintenance plate 105 is detachably arranged on the outside of the maintenance hole 106, thereby improving maintenance efficiency.

[0083] Reference Figure 2 As shown in the embodiment of this utility model, the outer shell 100 further includes a fixing plate 107, which is fixedly connected to the chassis 150. The fixing plate 107 is used to support the water outlet 170 and water inlet 180 of the water circuit module 500. The fixing plate 107 can ensure that the water outlet 170 and water inlet 180 are aligned with the external pipes, avoiding installation stress or poor sealing caused by misalignment, and improving the reliability of the heat pump equipment 1000.
