[0038] Reference Figure 1 and Figure 2As shown in the figure, a heat pump device 1000 provided in this embodiment of the present invention includes a housing 100, a heat pump assembly 200, an electrical control box 300, and an air duct assembly 400. The housing 100 has an inner cavity, and the heat pump assembly 200, the electrical control box 300, and the air duct assembly 400 are installed in the inner cavity and are respectively connected to the housing 100. The heat pump assembly 200 includes a compressor 210, a first heat exchanger 220, a second heat exchanger 230, and a throttling component. The compressor 210, the first heat exchanger 220, the second heat exchanger 230, and the throttling component are connected to form a refrigerant circulation loop.

[0039] Reference Figure 3 As shown, it can be understood that the heat pump device 1000 in this embodiment is an integrated heat pump. The inner cavity of the housing 100 is divided into an air inlet cavity 110 and an air outlet cavity 120. The top of the housing 100 is provided with an air inlet 130 and an air outlet 140. The air inlet 130 communicates with the air inlet cavity 110, and the air outlet 140 communicates with the air outlet cavity 120. The heat pump assembly 200 and the electrical control box 300 are installed in the air inlet cavity 110, and the air duct assembly 400 is installed in the air outlet cavity 120, resulting in a compact structure. The air duct assembly 400 includes a fan 410, which is used to draw outdoor air into the air inlet cavity 110 through the air inlet 130. After exchanging heat with the first heat exchanger 220, the air enters the air outlet cavity 120 and is discharged through the air outlet 140.

[0040] In some embodiments, the heat pump device 1000 may adopt a split structure. For example, the heat pump device 1000 has two housings 100. One housing 100 has a mounting cavity 111 in which the heat pump assembly 200 and the electrical control box 300 are installed. The mounting cavity 111 can be understood as the air inlet cavity 110. The air duct assembly 400 may be disposed in the air outlet cavity 120 of the other housing 100. The two housings 100 are connected, and air can flow through the air inlet cavity 110 and the air outlet cavity 120 in sequence for heat exchange.

[0041] Reference Figure 3 As shown, it can be understood that the first heat exchanger 220 is an evaporator 221, and the second heat exchanger 230 is a plate heat exchanger 231. The plate heat exchanger 231 includes refrigerant piping and water piping. The evaporator 221, the refrigerant piping of the plate heat exchanger 231, the throttling device, and the compressor 210 are connected to form a refrigerant circulation loop for refrigerant circulation. The water circuit assembly 500 includes a water pump, an inlet pipe 510, an outlet pipe 520, and a valve body. The inlet pipe 510 and the outlet pipe 520 are respectively connected to the water piping. The water pump can be installed on the inlet pipe 510 or the outlet pipe 520 to form a water supply pipeline.

[0042] During operation, the fan 410 draws outdoor air into the air inlet 110 through the air inlet 130 and blows it towards the evaporator 221. After exchanging heat with the evaporator 221, the air enters the air outlet 120 and is discharged through the air outlet 140. During operation, the refrigerant output from the compressor 210 passes through the plate heat exchanger 231, where it exchanges heat with the water flow through the refrigerant pipeline. Then, after throttling, the refrigerant enters the evaporator 221, where it exchanges heat with the outdoor air before returning to the compressor 210 for the next cycle. A water pump drives chilled water into the water flow pipeline of the plate heat exchanger 231, allowing the water to exchange heat with the refrigerant. Utilizing the outdoor air as a heat source, the system completes the cycle of absorbing heat from a low-temperature heat source and releasing heat to a high-temperature heat source, thus providing heating or hot water.

[0043] The heat pump device 1000 of this utility model embodiment can provide hot water through the outlet pipe 520 for supplying domestic hot water and heating. Alternatively, the outlet pipe 520 can be connected to a water tank to store the hot water for user use.

[0044] It should be noted that the heat pump unit 1000 operates for extended periods during heating. At low temperatures and high humidity, such as 4°C, the air flowing through the evaporator 221 absorbs heat, and the moisture in the air condenses on the evaporator 221 due to the temperature drop. Since the temperature of the evaporator 221 is below 0°C, the condensed water gradually condenses on the evaporator 221, eventually clogging it. Defrosting is then required, achieved by changing the refrigerant flow direction through a four-way valve and heating the evaporator 221. This process generates a significant amount of water vapor. Because the control box 300 and the evaporator 221 are located together, a large amount of water vapor condenses on the control box 300, placing high demands on its sealing. Problems arise from water vapor affecting the control box 300 during evaporator 221 defrosting. For example, water vapor can easily cause short circuits in the internal circuitry of the control box 300, posing a safety hazard. Some related technologies also include heat pump equipment that uses a large installation space to separate the electrical control box from the evaporator. However, the overall size of the heat pump equipment is also large, making it unsuitable for use in small spaces.

[0045] Based on this, in the embodiments of this utility model, a partition 600 is added inside the mounting cavity 111 to separate the mounting cavity 111 into a first mounting area and a second mounting area. The heat pump assembly 200 is placed in the first mounting area, and the electrical control box 300 is placed in the second mounting area. That is, the electrical control box 300 and the heat pump assembly 200 are arranged in different areas, so that the electrical control box 300 is separated from the first heat exchanger 220 and the second heat exchanger 230. The partition 600 can effectively block the water vapor during the defrosting process, reduce the water vapor entering the electrical control box 300, thereby reducing the risk of short circuit in the internal circuit of the electrical control box 300 due to water vapor and improving the stability of the heat pump equipment 1000.

[0046] Reference Figure 3 and Figure 4 As shown, specifically, the evaporator 221 is installed in the middle of the inner cavity of the housing 100. The evaporator 221 extends along the height direction of the housing 100, so that the evaporator 221 can separate the inner cavity to form an air inlet cavity 110 and an air outlet cavity 120. The air inlet cavity 110 can be understood as the mounting cavity 111 in the above embodiment. The air inlet cavity 110 is located on the right side, and the air outlet cavity 120 is located on the left side. The air inlet side of the evaporator 221 faces the air inlet cavity 110, and the air outlet side of the evaporator 221 faces the air outlet cavity 120. In this way, air can pass through the air inlet cavity 110 and the evaporator 221 into the air outlet cavity 120, realizing heat exchange between the air and the evaporator 221.

[0047] In this embodiment, a partition 600 is installed inside the air inlet cavity 110, separating the air inlet cavity 110 and forming a first installation area and a second installation area within the air inlet cavity 110, such as... Figure 3 As shown, the partition 600 extends along the height direction of the air inlet cavity 110, that is, the partition 600 divides the air inlet cavity 110 vertically. Along the front-rear direction of the housing 100, the first mounting area is located on the rear side of the partition 600, and the second mounting area is located on the front side of the partition 600. Figure 3 The area shown in P1 is the first installation area, and the area shown in P2 is the second installation area. The first and second installation areas are arranged along the front and rear direction of the housing 100.

[0048] It is understandable that the left edge of the evaporator 221 is used as the dividing line between the air inlet cavity 110 and the air outlet cavity 120, such as... Figure 3As shown in L1, the area to the right of the dividing line L1 is the air inlet chamber 110, and the area to the left of the dividing line L1 is the air outlet chamber 120. The compressor 210, evaporator 221, plate heat exchanger 231 and throttling device are all installed in the first installation area, and the electrical control box 300 is installed in the second installation area. The electrical control box 300 can be separated from the compressor 210, evaporator 221, plate heat exchanger 231 and throttling device by the partition 600.

[0049] To save installation space, the partition 600 inside the air inlet cavity 110 can be set around the electrical control box 300. For example, the partition 600 can be installed in the gap between the heat pump assembly 200 and the electrical control box 300. In this way, the partition 600 can separate the electrical control box 300 and reduce the space occupied, making the installation more compact without increasing the volume of the housing 100.

[0050] This is merely an example; the first and second installation areas can also be arranged along the left-right direction of the housing 100. Of course, the partition 600 is not limited to dividing the air inlet cavity 110 along the height direction. In some embodiments, the partition 600 can also divide the air inlet cavity 110 horizontally to form the first and second installation areas. For example, the first installation area is located below the second installation area, that is, the first and second installation areas are arranged along the height direction of the housing 100. In other embodiments, the partition 600 can also be inclined within the air inlet cavity 110, making the first and second installation areas wedge-shaped installation spaces respectively. The specific arrangement of the first and second installation areas can be set according to the actual installation requirements of the actual electrical control box 300.

[0051] It should be noted that when the heat pump device 1000 adopts a split structure, the heat pump component 200 and the electrical control box 300 are installed in the mounting cavity 111 of the same housing 100, and the partition 600 can be installed in the mounting cavity 111 using the installation method described in the above embodiment. Furthermore, the partition 600 used in the embodiment can be a metal plate, for example, the partition 600 can be formed by sheet metal stamping, resulting in high structural reliability. The partition 600 can also be a plastic plate, for example, the partition 600 can be made of materials such as polyvinyl chloride (PVC), which facilitates processing and installation.

[0052] Reference Figure 3As shown, in this embodiment, the evaporator 221 separates the air inlet chamber 110 from the air outlet chamber 120, requiring air to pass through the evaporator 221 before entering the air outlet chamber 120. The plate heat exchanger 231 is installed on one side of the inner wall of the housing 100, and the plate heat exchanger 231 is arranged opposite to the evaporator 221, that is, the evaporator 221 and the plate heat exchanger 231 are located on both sides of the air inlet chamber 110. The left end of the partition 600 is connected to the evaporator 221, and the right end of the partition 600 is connected to the plate heat exchanger 231. The partition 600 extends along the height direction of the air inlet chamber 110, thereby dividing the air inlet chamber 110 to form a first installation area and a second installation area arranged in the front-to-back direction.

[0053] The compressor 210, water circuit assembly 500 and plate heat exchanger 231 are located on the rear side of the partition 600. The compressor 210 and the corresponding refrigerant connection pipeline are close to the rear side of the housing 100. The water circuit assembly 500 is located between the compressor 210 and the partition 600, so that the installation area of ​​the heat pump assembly 200 and the installation area of ​​the water circuit assembly 500 can also be separated for easy maintenance.

[0054] Reference Figure 1 , Figure 2 and Figure 4 As shown, the front of the enclosure 100 has an opening 150 and a panel 160. The opening 150 communicates with the inner cavity, and the panel 160 is detachably installed at the opening 150. The opening 150 is located on the front of the enclosure 100, and can be opened or closed via the panel 160. It is understood that the electrical control box 300 is connected to the enclosure 100 near the opening 150. When the panel 160 is closed, it seals the air inlet cavity 110 and the air outlet cavity 120, preventing airflow leakage from the opening 150. Simultaneously, the panel 160 and the partition 600 define a second mounting area. When the panel 160 is open, the electrical control box 300 and the air duct assembly 400 are exposed, facilitating maintenance of components such as the electrical control box 300, the fan 410, and the heat pump assembly 200.

[0055] In some embodiments, the panel 160 and the housing 100 can be connected by a structure such as a snap fastener, screw, or lock, or they can be rotatably connected by a hinge structure such as a hinge or hinge. Different connection methods can be selected according to the actual application requirements.

[0056] in, Figure 2The image shows the heat pump unit 1000 without the electrical control box 300 installed. In this embodiment, the electrical control box 300 is generally rectangular. The second installation area and the first installation area are arranged sequentially from front to back. The electrical control box 300 and the plate heat exchanger 231 are located near the front of the housing 100. The partition 600 is connected between the evaporator 221 and the plate heat exchanger 231, which can effectively separate the second installation area. In this way, the electrical control box 300 is located in an independent installation area, which also facilitates maintenance.

[0057] Reference Figure 2 As shown, the partition 600 includes a first plate 610 and a second plate 620. The first plate 610 and the second plate 620 are connected sequentially along the direction from the evaporator 221 toward the plate heat exchanger 231. The first plate 610 is connected to the evaporator 221, and the second plate 620 is connected to the plate heat exchanger 231.

[0058] The first plate 610 is located near the side plate on the front side of the evaporator 221, and can be connected to the side plate by screws, fasteners, or other means. The first plate 610 is positioned between the evaporator 221 and the electrical control box 300, extending along the height of the evaporator 221 from its upper end to its lower end. Because of its proximity to the evaporator 221, the first plate 610 effectively separates the evaporator 221 from the electrical control box 300. When the evaporator 221 defrosts, water vapor mainly exits from the fins of the evaporator 221. At this time, the first plate 610, located near the evaporator 221, effectively prevents water vapor from entering the electrical control box 300, improving protection and reducing the safety risk of short circuits caused by water vapor entering the electrical control box 300.

[0059] The second plate 620 is located between the electrical control box 300 and the compressor 210. The compressor 210, water pump, valve body, and other components are all located on the rear side of the second plate 620. That is, the second plate 620 separates the rear side of the electrical control box 300 from the compressor 210, water pump, valve body, and corresponding refrigerant connection pipes, preventing water vapor from entering the second installation area from the rear side, thus better protecting the electrical control box 300.

[0060] Reference Figure 3 and Figure 5 As shown, it can be understood that the evaporator 221 and the electrical control box 300 are arranged side by side along the left and right directions of the housing 100. The first plate 610 is located on the left side of the electrical control box 300, and the second plate 620 is located on the rear side of the electrical control box 300. The first plate 610 and the second plate 620 are bent to form an angle, which can be greater than or equal to 90°, to ensure that the first plate 610 and the second plate 620 can be close to the electrical control box 300, reducing the space occupied.

[0061] It should be noted that the plate heat exchanger 231 is equipped with a bracket 232, which fixes the plate heat exchanger 231 to the inner wall of the housing 100, thereby securing the plate heat exchanger 231. The bracket 232 can be a sheet metal part, and it has mounting positions that match the plate heat exchanger 231, providing reliable support. The shell of the plate heat exchanger 231 can be connected to the bracket 232 by screws, welding, or other methods.

[0062] Reference Figure 5 As shown, the side of the bracket 232 closest to the electrical control box 300 is connected to the second plate 620, so that the bracket 232 can both support the plate heat exchanger 231 and fix the partition 600. This fixing method is stable and reliable, which can ensure the stability of the plate heat exchanger 231 during equipment operation and also enhance the installation strength of the partition 600.

[0063] Understandably, the partition 600, bracket 232 and panel 160 form a second installation area, making the installation structure more compact. The second installation area matches the electrical control box 300, making efficient use of space. Without increasing the volume of the box 100, the electrical control box 300 can be effectively separated.

[0064] It should be noted that, since the electrical control box 300 needs to be connected to the heat pump assembly 200 and the water circuit assembly 500, the wiring harness is led out from the left side of the electrical control box 300 near the evaporator 221. After adding a partition 600 for isolation, the wiring harness can be effectively protected from touching the evaporator 221. In addition, the wiring harness at the bottom of the electrical control box 300 can also be isolated to reduce the contact between the wiring harness and the internal water flow pipes, refrigerant connection pipes and other pipes, and facilitate wiring management.

[0065] Reference Figure 4 and Figure 6 As shown, in some embodiments, considering the heat dissipation requirements of the control box 300, the control box 300 is provided with a heat sink 310. The heat sink 310 is located on the side of the control box 300 facing the second plate 620, specifically at the upper rear end of the control box 300, and the heat sink 310 is specifically a heat dissipation fin. The upper end of the second plate 620 is provided with a first clearance opening 621. After the control box 300 is installed in the second installation area, the heat sink 310 is positioned facing the first clearance opening 621 to avoid the second plate 620 affecting the heat dissipation effect of the heat sink 310, ensuring that the heat sink 310 can fully contact the air and dissipate heat in a timely manner.

[0066] It should be noted that, as Figure 4As shown, the radiator 310 is exposed through the first clearance opening 621. Since the air inlet 130 is located at the top of the housing 100, the radiator 310 is close to the air inlet 130. Air enters the air inlet cavity 110 through the air inlet 130, which can quickly remove the heat from the radiator 310. Thus, the heat dissipation effect of the radiator 310 is not affected even when the partition 600 is added.

[0067] Reference Figure 2 As shown, in some embodiments, the bottom of the housing 100 is provided with a water inlet and a water outlet. The water inlet is connected to the water inlet pipe 510, and the water outlet is connected to the water outlet pipe 520. Parts of the water inlet pipe 510 and the water outlet pipe 520 need to be arranged within the second installation area. Therefore, in this embodiment, the lower end of the second plate 620 is provided with a second clearance opening 622. The second clearance opening 622 is used to avoid interference between the water circuit assembly 500 and the partition 600. In addition, the second clearance opening 622 also facilitates the routing of the wiring harness of the electrical control box 300, making wiring management easier.

[0068] Reference Figure 2 As shown, the first clearance opening 621 is a notch formed at the upper end of the second plate 620, and the second clearance opening 622 is a notch formed at the lower end of the second plate 620. When the evaporator 221 defrosts, water vapor mainly comes out from the fins of the evaporator 221. The first plate 610 can block most of the water vapor from entering the second installation area. Since the water vapor rises from bottom to top, the second clearance opening 622 is separated from the evaporator 221 by a certain distance, so the water vapor at the bottom is not easy to enter the second installation area through the second clearance opening 622. After the water vapor reaches the top, there is also a certain distance between the first clearance opening 621 at the top and the evaporator 221, and the water vapor will be carried away by the airflow of the air inlet 130. In this way, after the partition 600 divides the area, it can effectively prevent water vapor from condensing on the electrical control box 300.
