DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] In the related art, in order to save installation space, some heat pump water heaters integrate the refrigerant circulation loop and water flow pipeline into an all-in-one machine, also known as an integrated heat pump device, which is connected to the indoor space through a water pipe to supply the heat demand for domestic hot water and space heating. The electrical control box, refrigerant circulation loop, water flow pipeline and other components are arranged in the same space, and the internal structure layout is relatively compact. The electrical control box of the heat pump equipment is located below the top cover and above the middle partition. Therefore, the maintenance of the electrical control box requires disassembling the front panel, top cover and left and right side panels, and then loosening the fixing bolts of the electrical control box and the middle partition before starting to disassemble and assemble the electrical control box body, which makes it inconvenient to inspect the internal components; and most of the water circuit components are blocked by the electrical control box, requiring a large amount of side space for inspection.

[0027] Other heat pump products use an integrated casing. When maintenance is required, the entire casing must be removed first, and then the electrical control box must be disassembled before the internal components can be inspected. The operation is also relatively cumbersome, and many components are located on both sides of the fuselage, making it difficult to inspect directly from the front of the fuselage. It is necessary to enter both sides of the fuselage for maintenance, and it is also necessary to reserve maintenance space on the left and right sides of the fuselage.

[0028] Therefore, the integrated heat pump equipment in the related technology has certain requirements for the installation environment, and requires a certain amount of installation and maintenance space on the top or left and right directions, thereby occupying the limited indoor space and limiting the installation scene. In addition, since the evaporator needs to exchange heat with the outdoor environment, the heat pump equipment, as an outdoor unit, needs to be installed in the outdoor environment. Once the water circuit and other parts fail and need to be repaired, complex steps are required to complete the disassembly and maintenance, which will increase the cost; especially for residents on higher floors, the installers need to work in the outdoor high-altitude environment for installation and maintenance, which not only has high installation and maintenance costs, but also brings extremely high risks to the installation process.

[0029] To this end, an embodiment of the present invention provides a heat pump device 10, which adopts a flip-type electric control box 400 structure, and can realize quick operation to expose internal components, so as to facilitate the maintenance of the internal components. The heat pump device 10 is described below with a specific embodiment.

[0030] Reference Figure 1As shown, the heat pump device 10 of the embodiment of the present invention includes a housing 100, a heat pump assembly 200 and a fan 300. The housing 100 has an inner cavity, and the heat pump assembly 200 and the fan 300 are installed in the inner cavity; the front side of the housing 100 is provided with an opening 103 and a panel (not shown in the drawings), the opening 103 is connected to the inner cavity, and the panel is detachably installed at the opening 103, the opening 103 is located on the front side of the housing 100, and the opening 103 can be opened or closed by the panel. In some embodiments, the panel and the housing 100 can be connected by structures such as buckles, screws or locks, and can also be rotatably connected to the housing 100 by hinges, hinges and other articulated structures.

[0031] The heat pump assembly 200 includes a compressor 210, a first heat exchanger 220, a second heat exchanger 230 and a throttling component. The first heat exchanger 220 is arranged in the middle of the inner cavity of the box 100 and is arranged vertically along the height direction of the box 100. The inner cavity of the box 100 is divided into an air inlet cavity 101 and an air outlet cavity 102 by the first heat exchanger 220. The air inlet cavity 101 is located on the right side of the first heat exchanger 220, and the air outlet cavity 102 is located on the left side of the first heat exchanger 220. The compressor 210 and the second heat exchanger 230 are arranged in the air inlet cavity 101, and the fan 300 is arranged in the air outlet cavity 102.

[0032] In one embodiment, the first heat exchanger 220 is an evaporator, and the second heat exchanger 230 is a plate heat exchanger. The evaporator includes a first refrigerant pipeline 221, and the plate heat exchanger includes a second refrigerant pipeline 232 and a water pipeline 231. The plate heat exchanger is connected to the compressor 210 and the throttling component through the second refrigerant pipeline 232, and the evaporator is connected to the compressor 210 and the throttling component through the first refrigerant pipeline 221, forming a refrigerant circulation loop for the circulation of the refrigerant.

[0033] Reference Figure 2 As shown, the heat pump device 10 also includes a pipeline assembly 500, which is installed in the air inlet chamber 101. The pipeline assembly 500 includes a water pump 510, a water inlet pipe 520 and a water outlet pipe 530. The water inlet pipe 520 and the water outlet pipe 530 are respectively connected to the water flow pipeline 231. The water pump 510 can be set on the water inlet pipe 520 or the water outlet pipe 530 to form a water supply pipeline. When working, the refrigerant output by the compressor 210 passes through the plate heat exchanger, exchanges heat with water through the plate heat exchanger, and then enters the evaporator after throttling. After exchanging heat with air through the evaporator, it returns to the compressor 210 to enter the next cycle, and the cold water is driven into the plate heat exchanger by the water pump 510, so that the water and the refrigerant exchange heat, thereby producing hot water.

[0034] It should be noted that, refer to Figure 1As shown, the top of the box 100 is provided with an air inlet 131 and an air outlet 132, the air inlet 131 is connected to the air inlet chamber 101, the air inlet of the fan 300 is arranged toward the evaporator, and the air outlet of the fan 300 is connected to the air outlet 132. The air inlet 131 and the air outlet 132 are respectively provided with a duct connector 133, the air inlet 131 is connected to the air inlet duct through the duct connector 133, and the air outlet 132 is connected to the air outlet duct through the duct connector 133, and the air inlet duct and the air outlet duct are both connected to the outdoor environment, and the outdoor air enters the air inlet chamber 101 through the air inlet duct and the air inlet 131, the outdoor air exchanges heat with the evaporator, and enters the air outlet chamber 102, and then is discharged to the outdoor environment through the air outlet 132 and the air outlet duct. The air in the outdoor environment is used as a heat source, and heat is extracted through the heat exchange process, thereby achieving the heating of hot water. Figure 1 The directions indicated by the arrows are the directions of air inlet and air outlet respectively.

[0035] It is understandable that the heat pump device 10 of the embodiment of the present invention can provide hot water through the water outlet pipe 530 for supplying domestic hot water and heating hot water, or the water outlet pipe 530 can be connected to a water tank to store hot water in the water tank for use by users. Among them, the water inlet of the water inlet pipe 520 and the water outlet of the water outlet pipe 530 are both arranged on the chassis 110 of the box body 100 to avoid the visible area located on the front or side affecting the appearance structure. Since the heat load of the heat pump device 10 of the present invention is relatively small, in some embodiments, the heat pump device 10 can be linked with external equipment such as a gas wall-mounted boiler, an electric heater or a water tank to meet the user's use needs.

[0036] The heat pump equipment 10 is installed in an indoor environment, specifically in a basement, attic, garage, machine room, utility room and other scenes. The installation scenes are rich and there is no need to install it in an outdoor environment, thus eliminating the high installation cost, long installation time and high installation risk brought by the installation of an outdoor unit. The installation scene is not restricted by the aesthetics of the building's exterior surface, installation regulations and outdoor noise. The entire installation and maintenance process is performed indoors, with low installation and maintenance costs and simple operation. The shutdown process is not affected by the harsh outdoor environment, and there is no need to design a large amount of redundancy to prevent freezing of the water supply pipeline, thereby reducing production costs.

[0037] Reference Figure 1 and Figure 2 As shown, the heat pump device 10 of the embodiment also includes an electronic control box 400, which is used to electrically connect the compressor 210, the fan 300, the water pump 510, the sensor, the control valve and other components, and can also be connected to external equipment. For example, the water tank can be provided with a switch valve, and the electronic control box 400 can lead out a line and extend it to the outside of the box body 100, so that the line is connected to the switch valve to realize the control of the switch valve.

[0038] Specifically, the electric control box 400 is arranged at the opening 103 of the box body 100, and the electric control box 400 is rotatably connected to the box body 100. For example, the electric control box 400 is connected to the box body 100 by a hinged manner, so that the electric control box 400 can rotate around the hinged position to realize the flipping of the electric control box 400. In this way, the electric control box 400 can rotate toward the air inlet chamber 101 and move into the air inlet chamber 101 from the opening 103, so that the electric control box 400 is stored in the box body 100; it is also possible that when the electric control box 400 is located in the air inlet chamber 101, the electric control box 400 is flipped toward the outside of the box body 100, so that the electric control box 400 moves out of the air inlet chamber 101 from the opening 103.

[0039] It can be understood that the electronic control box 400 in the embodiment is roughly in the shape of a cuboid. Since the electronic control box 400 is arranged in the air inlet chamber 101 near the opening 103, the air inlet chamber 101 can be covered at the opening 103 through the electronic control box 400, and components such as the compressor 210, the plate heat exchanger, the first refrigerant pipeline 221, the second refrigerant pipeline 232, the water inlet pipe 520, the water outlet pipe 530 and the water pump 510 are all arranged in the air inlet chamber 101.

[0040] Reference Figure 2 As shown, in some embodiments, the compressor 210 is arranged near the back of the box body 100, the plate heat exchanger is fixedly connected to the side wall of the box body 100, the water pump 510 is located below the plate heat exchanger, and the first refrigerant pipeline 221, the second refrigerant pipeline 232 and the water flow pipeline 231 are arranged specifically according to the positions of the above-mentioned components. The above-mentioned components can be shielded by the electrical control box 400, and then the panel covers the opening 103, thereby shielding the internal structure of the box body 100.

[0041] Reference Figure 2 As shown, when the heat pump equipment 10 needs to be inspected and repaired, it is only necessary to open the panel and flip the electric control box 400 around the hinge position to move the electric control box 400 out of the air inlet chamber 101, and then the air inlet chamber 101 can be opened to expose the compressor 210, the second heat exchanger 230 and the pipe assembly 500, that is, the user can see the internal pipe assembly 500 and the refrigerant circulation loop on the front side of the box body 100, and it can be conveniently operated whether it is production or post-installation debugging and maintenance, and it is also convenient to replace parts without disassembling the electric control box 400; in addition, after the electric control box 400 is moved out of the air inlet chamber 101, it is also convenient to connect and repair the electric control box 400, and the operation is simple and quick, which effectively improves work efficiency.

[0042] Taking into account that the water supply pipeline is more prone to failure than the refrigerant pipeline, in one embodiment, the pipeline assembly 500 is arranged in the air inlet chamber 101 near the opening 103, that is, along the front and rear direction of the box body 100, the pipeline assembly 500 is arranged in front of the refrigerant pipeline and the compressor 210, which is more convenient for inspecting the pipeline assembly 500.

[0043] It should be noted that the fan 300 is located in the air outlet cavity 102, which is spaced apart from the air inlet cavity 101. After opening the panel, the fan 300 can be exposed, which is convenient for maintenance of the fan 300. In some embodiments, the fan 300 can be connected to the box 100 using a guide rail structure, which is convenient for moving the fan 300 out of the air outlet cavity 102 along the guide rail structure, and is more convenient for maintenance operations. The heat pump device 10 adopts the layout structure of the above embodiment, which has small space requirements and does not require a large amount of installation and maintenance space on both sides of the fuselage. All maintenance can be completed on the front side of the box 100, which is convenient for operation.

[0044] Reference Figure 1 and Figure 2 As shown, the box body 100 includes a chassis 110, a side panel 120, a top cover 130 and a panel, the side panel 120 defines an opening 103, the chassis 110 and the top cover 130 are respectively connected to the upper and lower ends of the side panel 120, and an inner cavity can be defined by the chassis 110, the side panel 120, the top cover 130 and the panel, and the air inlet 131 and the air outlet 132 are both arranged on the top cover 130.

[0045] Reference Figure 2 As shown, in some embodiments, the electric control box 400 is rotatably connected to the side panel 120 through a hinge structure 600, and the hinge position is located on the right side of the opening 103, and the electric control box 400 can be flipped toward the right side to move out of the air inlet chamber 101. The hinge structure 600 can be a hinge, a hinge, etc., and taking a hinge as an example, two hinges can be respectively connected to the two ends of the electric control box 400 in the height direction, and the two hinges are connected to the side panel 120, so that the electric control box 400 can be flipped.

[0046] Of course, the electrical control box 400 is not limited to being hinged to the side panel 120, but can also be connected to the top cover 130 or the chassis 110 through the hinge structure 600. For example, the upper end of the electrical control box 400 is hinged to the top cover 130, and can be flipped upward to open the air inlet chamber 101; for another example, the lower end of the electrical control box 400 is hinged to the chassis 110, and can be flipped downward to open the air inlet chamber 101.

[0047] In some embodiments, the hinge structure 600 includes a first hinge 610 and a second hinge 620. The first hinge 610 is fixedly connected to the side of the electric control box 400, and the second hinge 620 is fixedly connected to the edge of the side panel 120. The first hinge 610 is provided with a shaft sleeve, and the shaft sleeve is provided with an axis hole. The second hinge 620 is provided with a hinge shaft, and the hinge shaft is inserted into the axis hole, so that the first hinge 610 and the second hinge 620 can rotate relative to each other, thereby realizing the rotation of the electric control box 400 around the hinge shaft.

[0048] Since the shaft sleeve and the hinge shaft are connected in a sleeve-type manner, the shaft sleeve can move upward to be separated from the hinge shaft, so that the first hinge 610 and the second hinge 620 are separated, and the electric control box 400 and the box body 100 are disassembled and separated, which facilitates the installation and disassembly of the electric control box 400. In some other embodiments, a hinge shaft can be provided on the first hinge 610, and a shaft sleeve can be provided on the second hinge 620, so that the first hinge 610 and the second hinge 620 can also be disassembled and separated.

[0049] Reference Figure 1 and Figure 2 As shown, in order to fix the electric control box 400, in some embodiments, the right side of the electric control box 400 is connected to the side plate 120 through the above-mentioned hinge structure 600, and the left side of the electric control box 400 is provided with a lug 423, and the lug 423 is provided at the upper end of the electric control box 400. When the electric control box 400 is located in the air inlet cavity 101, it is connected to the top cover 130 through the lug 423 to achieve the function of fixing the electric control box 400. Specifically, the lug 423 and the top cover 130 are respectively provided with connecting holes, and bolts are passed through the connecting holes of the lug 423 and the top cover 130 to fix the electric control box 400, thereby preventing the electric control box 400 from swinging during use.

[0050] It is understandable that, since the hinge structure 600 supports and positions one side of the electric control box 400, only one bolt is needed to fix the electric control box 400 in the embodiment, thereby improving the maintenance efficiency. Of course, the lug 423 is not limited to being connected to the top cover 130 by bolts. For example, the lug 423 may be provided with a buckle, and the top cover 130 may be provided with a slot matching the buckle, so as to achieve rapid fixation by buckling.

[0051] In addition, when the electric control box 400 is close to the chassis 110, the lug 423 can be set at the lower end of the electric control box 400, and the lug 423 is connected to the chassis 110 by bolts or snap connections. The specific shape of the lug 423 can be selected according to the actual requirements of the product to meet the requirements of connecting with the top cover 130 or the chassis 110.

[0052] The above are some examples of the heat pump device 10 , and the specific structure of the electric control box 400 will be described below.

[0053] In the related art, the internal wiring socket and the external wiring socket in the heat pump water heater and the split air conditioner products are usually installed separately. Taking the heat pump water heater as an example, the internal wiring socket of the outdoor unit is set in the electric control component, and the external wiring socket is set on the shell. The shell is provided with an outlet corresponding to the external wiring socket, and the wiring of the external device is led out from the outlet. However, for the integral heat pump device, its internal space is relatively compact and is not suitable for the above scheme. Moreover, the heat pump device 10 of the present invention is installed in an indoor environment. Since it needs to exchange heat with the outdoor cold air, the internal temperature of the heat pump device 10 will be lower than the room temperature, which is easy to produce condensation, and the sealing and waterproof requirements of the electric control box 400 are relatively high. Therefore, the scheme using the related art is not suitable for the heat pump device 10 of the present invention.

[0054] Reference Figure 5 , Figure 6 and Figure 7 As shown, the electric control box 400 includes an electric control board 410, a box body 420, a first box cover 430 and a second box cover 440. The box body 420 has a first side and a second side that are arranged opposite to each other. The first side is provided with a first groove 421, and the second side is provided with a second groove 422. The first box cover 430 is arranged on the first side and covers the first groove 421. A first accommodating cavity 401 is defined between the first box cover 430 and the first groove 421. The second box cover 440 is arranged on the second side and covers the second groove 422. A second accommodating cavity 402 is defined between the second box cover 440 and the second groove 422. The electric control board 410 is installed in the first accommodating cavity 401. The box body 420 plays a role in fixing the electric control board 410. The electric control board 410 is wrapped by the box body 420 and the first box cover 430 to protect the electric control board 410.

[0055] Among them, the electric control board 410 is provided with an electric control element 411 and a plurality of wiring terminals 412, which are distributed on the side of the electric control box 400 facing the box cover, and the wiring terminals 412 are electrically connected to the internal compressor 210, fan 300, water pump 510, sensor, control valve and other components, and can also be electrically connected to external devices, for example, gas wall-mounted boilers, electric heaters or water tanks and other external devices. It can be understood that the electric control box 400 also includes a wiring assembly, and when the electric control board 410 is connected to an external device, some of the wiring terminals 412 of the electric control board 410 are electrically connected to the external device through the wiring assembly.

[0056] Specifically, the wiring assembly includes an internal wiring seat 450 and an external wiring seat 460, wherein the internal wiring seat 450 is arranged in the first accommodating chamber 401, the internal wiring seat 450 and the electric control board 410 are arranged side by side, and the external wiring seat 460 is arranged in the second accommodating chamber 402. The internal wiring seat 450 is electrically connected to the wiring terminal 412 through the first line 453, and the external wiring seat 460 is provided with a second line 463. The external wiring seat 460 leads out of the electric control box 400 and the box body 100 through the second line 463, and is connected to an external device. The first line 453 and the internal wiring seat 450 can be understood as a transfer line between the electric control board 410 and the internal wiring seat 450, which is connected to an external device through the second line 463 to achieve linkage with a gas wall-mounted boiler, an electric heater or a water tank. The second line 463 can specifically include a communication line such as a temperature sensing package and a control valve for connecting to external devices, and also includes a power line of the heat pump device 10. It can be understood that the internal wiring socket 450 and the external wiring socket 460 serve as wiring components between the electrical control board 410 and the external device, and the internal wiring socket 450 and the external wiring socket 460 are installed together in the electrical control box 400, that is, the internal wiring socket 450 and the external wiring socket 460 are integrated with the electrical control box 400, and there is no need to install the internal wiring socket 450 and the external wiring socket 460 separately, so the structure is more compact and saves more installation space.

[0057] In some embodiments, the first box cover 430 can be connected to the box body 420 by a buckle, or by bolts or other fixing methods. The second box cover 440 can be connected to the box body 420 by a buckle or bolt connection method. It is convenient to open the first box cover 430 and the second box cover 440 to inspect the electric control box 400.

[0058] Reference Figure 3 As shown, when the electric control box 400 is flipped and transferred into the box body 100, the first box cover 430 faces the air inlet chamber 101, and the second box cover 440 faces the front side of the box body 100. When the panel is opened, the second box cover 440 is exposed, which facilitates opening the second box cover 440. After the second box cover 440 is opened, the external wiring socket 460 is exposed, which facilitates wiring and maintenance of the external wiring socket 460.

[0059] Reference Figure 4 As shown, when the electric control box 400 is flipped out of the box body 100, the air inlet chamber 101 is opened to expose components such as the compressor 210, the plate heat exchanger and the pipeline assembly 500. At this time, the first box cover 430 is also exposed, which is convenient for opening the first box cover 430. After the first box cover 430 is opened, the electric control board 410 and the internal wiring socket 450 are exposed, which is convenient for wiring and maintenance of the electric control board 410 and the internal wiring socket 450.

[0060] It is understandable that part of the wiring terminals 412 is connected to the internal wiring seat 450. In the embodiment, the electric control board 410 is located above the internal wiring seat 450, and the two are arranged adjacent to each other, so the switching line used is also shorter, which is convenient for wiring and more reasonable. Part of the wiring terminals 412 can be directly connected to the compressor 210, the fan 300, the sensor and other components in the box 100, and the wiring operation is also simple, without the need to disassemble the electric control box 400.

[0061] It should be noted that, in the embodiment, the box body 420 is connected to the box body 100 via a hinge structure 600. When the first box cover 430 and the second box cover 440 are opened, the connection between the box body 420 and the box body 100 can be maintained without disassembling the box body 420, the electric control board 410, the internal wiring socket 450 and the external wiring socket 460, thereby facilitating wiring and maintenance operations.

[0062] In some embodiments, the internal terminal socket 450 and the external terminal socket 460 are arranged in a matched combination, that is, the number of the internal terminal socket 450 and the external terminal socket 460 are the same and they are arranged one by one. Since the internal terminal socket 450 and the external terminal socket 460 are arranged back to back, the box body 420 can be provided with a through groove connecting the first groove 421 and the second groove 422. The external terminal socket 460 can pass through the through groove to be connected to the internal terminal socket 450, and can be fixed by plugging or snapping, which is easy to assemble; moreover, after the internal terminal socket 450 and the external terminal socket 460 are assembled, the electrical connection between the internal terminal socket 450 and the external terminal socket 460 can be achieved through the metal conductive structure, and there is no need to arrange wires between the internal terminal socket 450 and the external terminal socket 460.

[0063] It should be noted that the internal wiring seat 450 includes an internal strong current wiring seat 451 and an internal weak current wiring seat 452, and the external wiring seat 460 includes an external strong current wiring seat 461 and an external weak current wiring seat 462. The external strong current wiring seat 461 is connected to the internal strong current wiring seat 451, and the external weak current wiring seat 462 is connected to the internal weak current wiring seat 452. The external strong current wiring seat 461 is used to connect strong current lines such as power lines, and the external weak current wiring seat 462 is used to connect weak current lines such as signal lines and control lines. It should be noted that the external strong current wiring seat 461 and the external weak current wiring seat 462 can be distinguished by sockets with different numbers of terminals, and the internal strong current wiring seat 451 and the internal weak current wiring seat 452 can also be distinguished by sockets with different numbers of terminals, so as to prevent wiring errors.

[0064] Reference Figure 6As shown, a sealing member 470 is provided between the first box cover 430 and the box body 420, and the sealing member 470 can improve the sealing between the first box cover 430 and the box body 420. Specifically, the sealing member 470 between the first box cover 430 and the box body 420 is a first sealing ring 471, and the first sealing ring 471 is arranged along the periphery of the first groove 421. When the first box cover 430 covers the first groove 421, the edge of the first box cover 430 abuts against the first sealing ring 471 to form a sealing structure, which can prevent water vapor from entering the first accommodating cavity 401.

[0065] In some embodiments, the first sealing ring 471 is rectangular and matches the shape of the first groove 421. The material of the first sealing ring 471 is rubber, which has better sealing performance, and can also be silicone or other elastic sealing materials. The specific shape of the first sealing ring 471 can be selected according to the actual shape of the first groove 421 and the first box cover 430. Exemplarily, the first sealing ring 471 can be a square or other polygonal shape.

[0066] Reference Figure 8 and Fig. 9 As shown, in some embodiments, a first recess 435 is provided on the edge of the first box cover 430 facing the box body 420, and the first recess 435 is provided along the circumference of the first box cover 430. The first sealing ring 471 is accommodated in the first recess 435. A first convex portion 4212 is provided on the edge of the box body 420. After the first box cover 430 and the box body 420 are assembled in place, the first convex portion 4212 enters into the first recess 435 and abuts against the first sealing ring 471. The first convex portion 4212 can press the first sealing ring 471 to achieve a better sealing effect.

[0067] The first recess 435 can be understood as an annular groove arranged around the first box cover 430, and a panel is arranged on the outer periphery of the box body 420, and the end of the panel is formed as a first convex portion 4212. In other embodiments, the first recess 435 can be arranged on the periphery of the box body 420, and the first convex portion 4212 can be arranged on the periphery of the first box cover 430. Exemplarily, the first recess 435 is formed on the end face of the panel facing the first box cover 430, and the first convex portion 4212 matches the first recess 435 accordingly.

[0068] Reference Figure 7 As shown, a sealing member 470 is provided between the second box cover 440 and the box body 420 . The sealing member 470 is a second sealing ring 472 . The second sealing ring 472 can improve the sealing performance between the second box cover 440 and the box body 420 .

[0069] It is understandable that if Figure 7As shown, the groove on the side of the box body 420 facing away from the electronic control board 410 is the second groove 422, and the second sealing ring 472 is arranged along the circumference of the second groove 422. When the second box cover 440 covers the second groove 422, the edge of the second box cover 440 abuts against the second sealing ring 472 to form a sealing structure, thereby preventing water vapor from entering the second accommodating cavity 402.

[0070] Reference Figure 8 and Fig.10 As shown, in some embodiments, a second recess 4223 is provided on the end surface of the box body 420 facing away from the first accommodating cavity 401, and the second recess 4223 is arranged around the notch of the second groove 422, and the second sealing ring 472 is accommodated in the second recess 4223. After the second box cover 440 and the box body 420 are assembled in place, the second box cover 440 and the second sealing ring 472 are abutted, and the second box cover 440 can be used to press the second sealing ring 472 to achieve a better sealing effect.

[0071] In one embodiment, a step surface 4222 may be provided between the end surface of the box body 420 and the second groove 422, and the second recess 4223 may be an annular groove formed on the step surface 4222. The step surface 4222 matches the second box cover 440, so that the second box cover 440 can be flush with the end surface of the box body 420 when covering the second groove 422, that is, the second box cover 440 does not protrude from the surface of the box body 420, and the sealing is better.

[0072] Reference Fig.10 As shown, since the external terminal socket 460 needs to be connected to the external device through the second line 463, a first line outlet 4221 for the second line 463 to pass through is provided on the box body 420. In the embodiment, the first line outlet 4221 is arranged on the side wall of the second groove 422, and a sealing member 470 is provided at the first line outlet 4221. Specifically, the first line passing card 480 is used to seal the first line outlet 4221, so that the second line 463 is led out from the first line outlet 4221, and at the same time, it can ensure that the first line outlet 4221 has a high sealing performance, thereby preventing water vapor from entering the electric control box 400 from the first line outlet 4221.

[0073] In one embodiment, the first wire outlet 4221 is a notch formed on the side wall of the second groove 422, that is, the side of the first wire outlet 4221 facing the second box cover 440 is an open structure, so that the first wire pass card 480 can be assembled into the first wire outlet 4221 from the open structure. In order to match the sealing structure of the second groove 422 and the notch, in the embodiment, the second box cover 440 includes a first plate body 441 and a second plate body 442 connected, wherein the first plate body 441 covers the second groove 422, and the second plate body 442 covers the notch, so that the second box cover 440 can match the arrangement of the second groove 422 and the first wire outlet 4221.

[0074] It should be noted that, refer to Figure 7 As shown, the second sealing ring 472 includes a first sealing section 4721 and a second sealing section 4722. The first sealing section 4721 matches the shape and size of the second groove 422. The first sealing section 4721 cooperates with the first plate 441 to seal the second groove 422. The second sealing section 4722 matches the shape and size of the notch. The second sealing section 4722 cooperates with the second plate 442 to seal the first outlet card, thereby ensuring that the first outlet port 4221 has better sealing performance.

[0075] The material of the second sealing ring 472 can be rubber, silicone or other elastic sealing materials. The first sealing section 4721 and the second sealing section 4722 adopt an integrally formed structure, and the specific shapes of the first sealing section 4721 and the second sealing section 4722 can be selected according to the actual shapes of the second groove 422 and the first outlet 4221 to match the structure of the second groove 422 and the first outlet 4221.

[0076] Reference Figure 3 As shown, the chassis 110 is provided with a third outlet, and the third outlet is for the second line 463 to pass through the box 100. The third outlet is provided with a sealing body 111, and the third outlet is sealed by the sealing body 111. When the second line 463 is led out from the third outlet, it is sealed with the sealing body 111, which can ensure that the third outlet has a high sealing performance, avoid indoor air from entering the box 100 from the third outlet, and reduce the condensation phenomenon. In the embodiment, the sealing body 111 can be a sealing kit made of rubber, silicone and other materials. The sealing kit is sleeved on the second line 463 to maintain close contact and have a better sealing effect.

[0077] It should be noted that some of the wiring terminals 412 are provided with a third line 4121, and the electric control board 410 is electrically connected to the compressor 210, the fan 300, the sensor and other components in the box body 100 through the third line 4121. Therefore, the box body 420 is provided with a second line outlet 4211 for the third line 4121 to pass through, and a second line passing card 490 is provided in the second line outlet 4211. The second line passing card 490 is used to seal the second line outlet 4211, so that the third line 4121 is led out from the second line outlet 4211, while ensuring that the second line outlet 4211 has a high sealing performance, thereby preventing water vapor from entering the electric control box 400 from the second line outlet 4211.

[0078] In some embodiments, the first wire pass card 480 and the second wire pass card 490 adopt the same structure to ensure that the outlet position of the electric control box 400 has better sealing performance. Fig.10 As shown, taking the first wire passing card 480 as an example, the first wire passing card 480 includes a wire passing card body 481, and the wire passing card body 481 is provided with a wire passing groove 482, and a plurality of sealing sheets 483 are respectively provided at both ends of the wire passing groove 482, and the plurality of sealing sheets 483 are arranged along the inner circumferential wall of the wire passing groove 482, and adjacent sealing sheets 483 abut against each other. The second line 463 can pass through between adjacent sealing sheets 483 and remain abutted against the sealing sheets 483 to form an effective sealing structure.

[0079] It can be understood that the entire line card body 481 is made of elastic material, such as rubber or silicone, and the sealing sheet 483 has a certain elasticity. When the second line 463 passes through the adjacent sealing sheet 483, the sealing sheet 483 can be deformed and maintain contact with the second line 463, and the sealing performance is stable.

[0080] Reference Fig.10 As shown, the extension direction of the wire groove 482 is consistent with the extension direction of the first wire outlet 4221. In the embodiment, two first wire-passing cards 480 can be set at the first wire outlet 4221 to seal the strong current line and the weak current line respectively. When the second line 463 passes through the first wire outlet 4221, the second line 463 enters the wire groove 482, and the two ends of the wire groove 482 are sealed respectively by the sealing sheet 483, which can effectively prevent water vapor from entering the electric control box 400. The specific structure of the second wire-passing card 490 can refer to the structure of the first wire-passing card 480 mentioned above. It should be noted that the specific number of the first wire-passing card 480 and the second wire-passing card 490 can be selected according to the number of the first wire outlet 4221 and the second wire outlet 4211.

[0081] The electric control element 411 of the electric control board 410 includes a first heating device, which may be a rectifier bridge, an intelligent power module, an insulated gate bipolar transistor, etc. In the embodiment, the electric control board 410 is further provided with a heat sink 700, which is arranged on the side of the electric control board 410 facing the box cover and abuts against the heating surface of the first heating device. The heat of the first heating device can be taken away by the heat sink 700. The heat sink 700 may be a fin heat sink, and the heat sink 700 may also be in contact with two or more first heating devices at the same time for heat dissipation. For example, the rectifier bridge and the intelligent power module are arranged adjacent to each other, and the heat sink 700 is in contact with the heating surfaces of the rectifier bridge and the intelligent power module, so that the rectifier bridge and the intelligent power module can be cooled at the same time.

[0082] Reference Figure 8 and Fig. 9 As shown, in some embodiments, the first box cover 430 is provided with a through hole 431, the size of the through hole 431 matches the size of the radiator 700, so that the radiator 700 can pass through the through hole 431, and at least part of the radiator 700 is exposed outside the first box cover 430. A third sealing ring 473 is arranged between the radiator 700 and the first box cover 430, and part of the structure of the radiator 700 is exposed from the through hole 431. A flange 710 is arranged on the outer peripheral edge of the radiator 700 on the side facing the electric control board 410. The third sealing ring 473 is arranged around the radiator 700 and one side thereof abuts against the flange 710. When the first box cover 430 and the box body 420 are assembled, the first box cover 430 abuts against the other side of the third sealing ring 473 and presses the third sealing ring 473, thereby fixing the third sealing ring 473, so that the radiator 700 and the first box cover 430 have a higher sealing performance, thereby improving the overall sealing performance of the electric control box 400.

[0083] It is understandable that when the electric control box 400 is located in the air inlet cavity 101, the first box cover 430 and the radiator 700 are both facing the air inlet cavity 101, and the side of the box body 420 facing away from the electric control board 410 is facing the front of the box body 100. When the heat pump device 10 is working, the air from the outdoor environment will enter the air inlet cavity 101 and flow along the air inlet cavity 101 to the evaporator, and part of the air flow will pass through the radiator 700, thereby helping to improve the heat dissipation efficiency of the radiator 700.

[0084] In some embodiments, reference Figure 8 As shown, the radiator 700 is arranged at the upper end of the electric control box 400, and after the electric control box 400 enters the air inlet cavity 101, the radiator 700 is arranged close to the air inlet 131, which is more conducive to the air flow passing through the radiator 700, and the heat dissipation effect is better. It should be noted that the airflow takes away the heat of the radiator 700 and then exchanges heat with the evaporator, which can recover the heat taken away by the airflow and improve the heating efficiency.

[0085] The embodiment of the present invention arranges the electric control element 411, the wiring terminal 412 and the heat sink 700 on the side of the electric control board 410 facing the first box cover 430, which can facilitate the heat dissipation of the heat sink 700 on the one hand and the wiring of the wiring terminal 412 on the other hand, while ensuring that the wiring and the heat sink 700 are located on the same side of the electric control board 410, without the need for special production processes, and is convenient for production and manufacturing.

[0086] It should be noted that the electric control element 411 also includes a second heating device, which is a device with a non-encapsulated structure, generates heat when working, and needs to be provided with waterproof protection measures. Therefore, in some embodiments, the second heating device is arranged in the electric control box 400, and an air duct 432 is arranged on the electric control box 400 to dissipate heat from the second heating device by using the air duct 432. The second heating device can be an inductor 4111 or other heating devices.

[0087] Reference Figure 6 and Figure 8 As shown, taking the inductor 4111 as an example for explanation, the inductor 4111 is arranged on the side of the electric control box 400 facing the first box cover 430, and the air duct 432 is formed on the first box cover 430. The first box cover 430 is provided with an air inlet 433 and an air outlet 434, and the air inlet 433 and the air outlet 434 are respectively connected to the air duct 432, wherein the air inlet 433 is arranged toward the radiator 700, and the air outlet 434 is arranged on the side wall of the first box cover 430. When the electric control box 400 is flipped over and enters the air inlet chamber 101, the air outlet 434 faces the evaporator, and at least part of the structure of the inductor 4111 is located in the air duct 432.

[0088] When the heat pump device 10 is working, the air from the outdoor environment will enter the air inlet chamber 101 and flow toward the evaporator along the air inlet chamber 101. Part of the air flow will enter the air duct 432 through the air inlet 433 after passing through the radiator 700, and flow toward the inductor 4111 along the air duct 432, and then be discharged from the air outlet 434. Figure 8 As shown, Figure 8 The direction indicated by the middle arrow is the direction of the air flow along the air duct 432 .

[0089] It should be noted that, since the evaporator is close to the air outlet 434 of the air duct 432, when the airflow of the air inlet chamber 101 passes through the evaporator, the airflow velocity discharged from the air outlet 434 is accelerated, resulting in a suction effect, so the airflow circulation of the inductor 4111 can be improved through the air duct 432. Moreover, since the air inlet 433 faces the radiator 700, the wind speed passing through the radiator 700 can be accelerated at the same time, which is beneficial to improving the heat dissipation efficiency of the radiator 700.

[0090] The embodiment of the present invention also provides a hot water heating system, including the heat pump device of the above embodiment. The heat pump device 10 can be connected to external devices such as a gas wall-mounted boiler, an electric heater or a water tank to form a hot water heating system, which provides domestic hot water and heating hot water to users. The hot water heating system has all the beneficial effects of the above heat pump device 10.

[0091] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
