DETAILED DESCRIPTION

[0023] 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.

[0024] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, left, right, front, back, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying 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.

[0025] 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.

[0026] 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.

[0027] 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 of 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 the removal of the panel, top cover and left and right side panels, and then the fixing bolts of the electrical control box and the middle partition are loosened before the electrical control box body can be disassembled and assembled. There is a problem of inconvenience in the maintenance of internal components; and most of the water circuit components are blocked by the electrical control box, requiring a large amount of side space for maintenance.

[0028] 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 repaired. The operation is also relatively cumbersome, and many components are located on both sides of the machine, making it difficult to repair them directly from the front of the machine. It is necessary to enter both sides of the machine for maintenance, and maintenance space must be reserved on the left and right sides of the machine.

[0029] 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.

[0030] To this end, an embodiment of the present invention provides a heat pump device that can realize quick operation to expose internal components, making it easier to inspect and repair the internal components. The heat pump device is described below with a specific embodiment.

[0031] Reference Figure 1 and Figure 2 As 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 assembly 300, the housing 100 has an inner cavity, and the heat pump assembly 200 and the fan assembly 300 are installed in the inner cavity; the front side of the housing 100 is provided with an opening 103 and a panel 140, the opening 103 is connected to the inner cavity, and the panel 140 is detachably installed at the opening 103, and the opening 103 can be opened or closed by the panel 140.

[0032] In some embodiments, locks 150 are respectively provided on both sides of the panel 140, and the panel 140 is connected to the side panel 120 of the box 100 through the locks 150, so that the panel 140 can be quickly disassembled. After opening the panel 140, the internal structure of the machine can be exposed, which is convenient for installation and maintenance. Exemplarily, the panel 140 and the side panel 120 can also be connected by structures such as buckles and screws. In some other embodiments, the panel 140 can also be rotatably connected to the side panel 120 through an articulated structure such as a hinge or hinge to flip open the panel 140.

[0033] Reference Figure 2 and Figure 3 The heat pump assembly 200 includes a compressor 210, a first heat exchanger 220, a second heat exchanger 230, a throttling component and a refrigerant pipeline. The first heat exchanger 220 is arranged in the middle 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, the second heat exchanger 230, the throttling component and the refrigerant pipeline are arranged in the air inlet cavity 101, and the fan assembly 300 is arranged in the air outlet cavity 102.

[0034] In some embodiments, the first heat exchanger 220 is an evaporator, the second heat exchanger 230 is a plate heat exchanger, the refrigerant pipeline includes a first refrigerant pipeline 221 and a second refrigerant pipeline 232, the plate heat exchanger includes a refrigerant flow path and a water flow pipeline 231, the evaporator is connected to the compressor 210 and the throttling component respectively through the first refrigerant pipeline 221, and the refrigerant flow path of the plate heat exchanger is connected to the compressor 210 and the throttling component respectively through the second refrigerant pipeline 232, so that the compressor 210, the first heat exchanger 220, and the second heat exchanger 230 are connected through the refrigerant pipeline to form a refrigerant circulation loop for the circulation of the refrigerant.

[0035] Reference Figure 3 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 outdoor 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.

[0036] It should be noted that, refer to Figure 1 and Figure 2 As shown, the top of the box body 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 301 of the fan assembly 300 is arranged toward the evaporator, and the air outlet 302 of the fan assembly 300 is connected to the air outlet 132. In one embodiment, the air inlet 131 and the air outlet 132 are respectively provided with an air guide ring 133, which has a wind guiding function. Alternatively, the air inlet 131 is connected to the air inlet pipe through the air guide ring 133, and the air outlet 132 is connected to the air outlet pipe through the air guide ring 133. Both the air inlet pipe and the air outlet pipe are connected to the outdoor environment, and the outdoor air enters the air inlet chamber 101 through the air inlet pipe and the air inlet 131, and 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 pipe. The air in the outdoor environment is used as a heat source to extract heat through a heat exchange process, thereby heating hot water. Figure 1 The directions indicated by the arrows are the directions of air inlet and air outlet respectively.

[0037] 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 116 of the water inlet pipe 520 and the water outlet 117 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.

[0038] 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.

[0039] Reference Figure 2 As shown, the heat pump device 10 also includes an electrical control box 400, which is used to electrically connect the compressor 210, the fan assembly 300, the water pump 510, the sensor, the control valve and other components, and can also be connected to external equipment. For example, a switch valve can be set in the water tank, and the electrical control box 400 can lead out the 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.

[0040] In some embodiments, the electric control box 400 is installed near the opening 103 of the box body 100, and the electric control box 400 can be installed on the side wall of the side plate 120 or the chassis 110. The electric control box 400, the pipeline assembly 500 and the compressor 210 are arranged in sequence from front to back along the front and rear direction of the box body 100, and the first refrigerant pipeline 221 and the second refrigerant pipeline 232 are arranged near the compressor 210. Therefore, it can be understood that the electric control box 400, the pipeline assembly 500 and the refrigerant pipeline are arranged in sequence from front to back. When the heat pump device 10 needs to be repaired, the panel 140 is opened and the electric control box 400 is removed, and the pipeline assembly 500 and the refrigerant pipeline can be exposed, that is, the pipeline assembly 500 and the refrigerant pipeline can be directly seen from the front side. Since the pipeline assembly 500 has a higher failure rate than the refrigerant pipeline, the pipeline assembly 500 is arranged on the front side of the refrigerant pipeline, which is more convenient for maintenance and effectively improves work efficiency.

[0041] Reference Figure 3 As shown, in some embodiments, 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 be rotated toward the air inlet cavity 101, and move into the air inlet cavity 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 cavity 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 cavity 101 from the opening 103.

[0042] It can be understood that the electric control box 400 in the embodiment is roughly in the shape of a cuboid. Since the electric control box 400 is arranged near the opening 103 of the air inlet cavity 101, the air inlet cavity 101 can be covered at the opening 103 by the electric control box 400. 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 cavity 101. Figure 3 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 140 covers the opening 103, thereby shielding the internal structure of the box body 100.

[0043] Reference Figure 3As shown, when the heat pump equipment 10 needs to be inspected and repaired, it is only necessary to open the panel 140, flip the electric control box 400 around the hinge position, and move the electric control box 400 out of the air inlet chamber 101, so that the air inlet chamber 101 can be opened, so that the pipeline assembly 500, the compressor 210, the second heat exchanger 230 and the refrigerant pipeline are exposed, that is, the user can see the pipeline assembly 500 and the refrigerant circulation loop on the front side of the box body 100, whether it is production or post-installation debugging, maintenance, etc., it can be conveniently operated, 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, the operation is simple and fast, and the work efficiency is effectively improved.

[0044] It should be noted that the fan assembly 300 is located in the air outlet cavity 102, which is spaced apart from the air inlet cavity 101. After opening the panel 140, the fan assembly 300 can be exposed, which is convenient for maintenance of the fan assembly 300. In some embodiments, the fan assembly 300 can be connected to the housing 100 using a guide structure 340, which is convenient for moving the fan assembly 300 along the guide structure 340 from the opening 103 into or out of the air outlet cavity 102, which is 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 to be reserved on both sides of the machine. All maintenance can be completed on the front side of the housing 100, which is convenient for operation.

[0045] Reference Figure 2 As shown, the box body 100 includes a chassis 110, a side panel 120, a top cover 130 and a panel 140, an opening 103 is provided on one side of the side panel 120, the chassis 110 and the top cover 130 are respectively connected to the upper and lower ends of the side panel 120, an inner cavity can be defined by the chassis 110, the side panel 120, the top cover 130 and the panel 140, and the air inlet 131 and the air outlet 132 are both provided on the top cover 130.

[0046] Reference Figure 3 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.

[0047] 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.

[0048] Reference Figure 4 and Figure 6 As shown, 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 611, and the shaft sleeve 611 is provided with an axis hole, and the second hinge 620 is provided with a hinge axis 621, and the hinge axis 621 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 axis 621.

[0049] by Figure 6 The example shown is used for illustration, because the shaft sleeve 611 and the hinge shaft 621 are connected in a sleeve manner, the shaft sleeve 611 can move upward to disengage from the hinge shaft 621, 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, the hinge shaft 621 can be provided on the first hinge 610, and the shaft sleeve 611 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.

[0050] Reference Figure 2 and Figure 5 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 hinge structure 600, and the left side of the electric control box 400 is provided with a lug 423, which 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, the lug 423 is connected to the top cover 130 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 134, and bolts are passed through the connecting holes 134 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In the related art, the internal terminal socket 450 and the external terminal socket 460 in the heat pump water heater and split air conditioner products are usually installed separately. Taking the heat pump water heater as an example, the internal terminal socket 450 of the outdoor unit is set in the electric control component, and the external terminal socket 460 is set on the shell. The shell is provided with an outlet corresponding to the external terminal socket 460, and the wiring of the external device is led out from the outlet. However, for the integral heat pump device 10, 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.

[0055] Reference Figure 7 , Figure 8 and Fig. 9 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.

[0056] 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, the fan assembly 300, the water pump 510, the sensor, the 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 is understandable that the electric control box 400 also includes a wiring assembly, and when the electric control board 410 is connected to the 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.

[0057] 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 and the wiring terminal 412 are electrically connected through the first line 403, and the external wiring seat 460 is provided with a second line 404. The external wiring seat 460 leads out of the electric control box 400 and the box body 100 through the second line 404, and is connected to an external device. The first line 403 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 404 to achieve linkage with a gas wall-mounted boiler, an electric heater or a water tank. The second line 404 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.

[0058] 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.

[0059] Reference Figure 2As 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 140 is opened, the second box cover 440 can be exposed, which facilitates opening the second box cover 440. After the second box cover 440 is opened, the external wiring socket 460 can be exposed, which facilitates wiring and maintenance of the external wiring socket 460.

[0060] Reference Figure 3 and 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.

[0061] 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 assembly 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.

[0062] 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.

[0063] In some embodiments, the internal terminal socket 450 and the external terminal socket 460 are arranged in a paired matching 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 connecting groove connecting the first groove 421 and the second groove 422. The external terminal socket 460 can be connected to the internal terminal socket 450 through the connecting groove, and can be fixed by plugging or snapping, etc., 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 a wire between the internal terminal socket 450 and the external terminal socket 460.

[0064] 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 using wiring seats 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 using wiring seats with different numbers of terminals, so as to prevent wiring errors.

[0065] Reference Figure 8 As 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.

[0066] 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.

[0067] Reference Fig.10 and Fig.11 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.

[0068] 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.

[0069] Reference Fig. 9 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 .

[0070] It is understandable that if Fig. 9 As 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.

[0071] Reference Fig. 9 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.

[0072] 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.

[0073] Reference Fig. 9As shown, since the external terminal block 460 needs to be connected to an external device through the second line 404, a first line outlet 4221 for the second line 404 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 404 is led out from the first line outlet 4221 while ensuring 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.

[0074] 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.

[0075] It should be noted that, refer to Fig. 9 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.

[0076] 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.

[0077] Reference Figure 2As shown, the chassis 110 is provided with a third wire outlet 118, and the third wire outlet 118 is for the second line 404 to pass through the box 100. The third wire outlet 118 is provided with a sealing body 114, and the third wire outlet 118 is sealed by the sealing body 114. When the second line 404 is led out from the third wire outlet 118, it is sealed with the sealing body 114, which can ensure that the third wire outlet 118 has a high sealing performance, prevent the indoor air from entering the box 100 from the third wire outlet 118, and reduce the condensation phenomenon. In the embodiment, the sealing body 114 can be a sealing kit made of rubber, silicone and other materials. The sealing kit is sleeved on the second line 404 to maintain close contact and have a better sealing effect.

[0078] It should be noted that some of the wiring terminals 412 are provided with a third line 405, and the electric control board 410 is electrically connected to the compressor 210, the fan assembly 300, the sensor and other components in the box body 100 through the third line 405. Therefore, the box body 420 is provided with a second line outlet 4211 for the third line 405 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 405 can be led out from the second line outlet 4211 while ensuring that the second line outlet 4211 has a high degree of sealing, thereby preventing water vapor from entering the electric control box 400 from the second line outlet 4211.

[0079] 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. Taking the first wire pass card 480 as an example, the first wire pass card 480 includes a wire pass card body, the wire pass card body is provided with a wire pass slot, and a plurality of sealing sheets are respectively provided at both ends of the wire pass slot, and the plurality of sealing sheets are arranged along the inner peripheral wall of the wire pass slot, and adjacent sealing sheets abut against each other, and the second line 404 can pass between adjacent sealing sheets and keep abutting against the sealing sheets to form an effective sealing structure.

[0080] It is understandable that the entire body of the line card is made of elastic material, such as rubber or silicone, and the sealing sheet has a certain elasticity. When the second line 404 passes through the adjacent sealing sheet, the sealing sheet can be deformed and maintain contact with the second line 404, and the sealing performance is stable.

[0081] The extension direction of the wire groove is consistent with the extension direction of the first wire outlet 4221. In the embodiment, two first wire clips 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 404 passes through the first wire outlet 4221, the second line 404 enters the wire groove, and the two ends of the wire groove are sealed by the sealing sheet, which can effectively prevent water vapor from entering the electric control box 400. The specific structure of the second wire clip 490 can refer to the structure of the first wire clip 480 mentioned above. It should be noted that the specific number of the first wire clip 480 and the second wire clip 490 can be selected according to the number of the first wire outlet 4221 and the second wire outlet 4211.

[0082] 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 700, 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.

[0083] Reference Fig.10 and Fig.11 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.

[0084] 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.

[0085] In some embodiments, reference Fig.10 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.

[0086] 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.

[0087] 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 a heat dissipation channel 432 is arranged on the electric control box 400 to dissipate heat from the second heating device by using the heat dissipation channel 432. The second heating device can be an inductor 4111 or other heating devices.

[0088] Reference Fig.10 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 heat dissipation channel 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 heat dissipation channel 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 heat dissipation channel 432. Fig.10 The direction indicated by the middle arrow is the direction of airflow flowing along the heat dissipation channel 432 .

[0089] When the heat pump device 10 is working, 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 airflow will pass through the radiator 700. After passing through the radiator 700, part of the airflow will enter the heat dissipation channel 432 through the air inlet 433 and flow toward the inductor 4111 along the heat dissipation channel 432, and then be discharged from the air outlet 434.

[0090] It should be noted that, since the evaporator is close to the air outlet 434 of the heat dissipation channel 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 heat dissipation channel 432. In addition, 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.

[0091] Reference Fig.12 As shown, in one embodiment, the guide structure 340 includes a guide rail, which is located in the air outlet cavity 102 and connected to the side plate 120 or the chassis 110, and the guide rail is arranged along the direction from the opening 103 toward the inner side of the air outlet cavity 102. The fan assembly 300 includes a duct structure 310, a fan body 320 and a shell 330. The duct structure 310 is connected in the shell 330. An air duct is formed in the duct structure 310. The air inlet 301 and the air outlet 302 are respectively connected to the air duct. The air duct is arranged toward the first heat exchanger 220, and the fan body 320 is arranged in the air duct. Among them, the shell 330 is a sheet metal part, which improves the protection and support of the duct structure 310. The shell 330 is connected to the guide rail so that the fan assembly 300 can move along the guide rail. It should be noted that after the fan assembly 300 is moved into the air outlet cavity 102, the shell 330 can be fixed to the box body 100 by screws or snap connections to achieve the purpose of positioning the fan assembly 300. It is understandable that, during the maintenance process, after opening the panel 140, the screws can be removed to move the fan assembly 300 out of the air outlet cavity 102 along the guide rail, which is convenient for maintenance of the fan assembly 300, and dust inside the air duct can also be cleaned. In addition, only one screw needs to be removed to realize the flipping of the electric control box 400, and the maximum flip angle of the electric control box 400 can reach 145°. The wiring terminal 412 of the electric control board 410 is located on the back of the electric control box 400, and the external wiring seat 460 is located on the front of the electric control box 400. In this way, when installing an external device, only the second box cover 440 of the electric control box 400 needs to be opened to expose the internal external wiring seat 460. During the wiring process, there is no need to touch the main control board, avoiding interference and damage to the main control board, and protecting the long-term stable operation of the electric control box 400 to the greatest extent. By flipping the electric control box 400, the internal pipeline assembly 500 and the refrigerant pipeline can be exposed, and most of the internal parts can be touched from the front, which is convenient for maintenance and replacement.

[0092] Reference Fig.13 As shown, the air duct structure 310 includes a volute 311, an air guide plate 312 and a reinforcement structure 313. The volute 311 forms an air duct. An opening is provided on one side of the volute 311. The opening is used for the fan body 320 to enter or leave the air duct. The fan body 320 includes a motor and a wind wheel 321 connected to the drive shaft of the motor. The wind guide plate 312 covers the opening. The air inlet 301 is formed on the wind guide plate 312. The wind guide plate 312 is arranged vertically. The opening is circular, which is more matched with the shape of the wind wheel 321 of the fan. The shell 330 and the wind guide plate 312 are surrounded to form a cavity for accommodating the volute 311. The shell 330 is used to be connected to the fan and can stably support the fan.

[0093] The shell 330 is covered on the side of the volute 311 away from the air guide plate 312. The shell 330 includes a front side plate 120, a rear side plate 120, a lower side plate 120 and a left side plate 120 connected to each other. The axis of the volute 311 is arranged along the left and right direction. During the assembly process, the volute 311 can be installed in the shell 330 from right to left. The lower side plate 120 supports the volute 311. The front side plate 120 and the rear side plate 120 block the volute 311 in the front and rear directions. The left side plate 120 blocks the left side of the volute 311, which plays a limiting and protective role on the volute 311. The fan is connected to the left side plate 120. The shell 330 is a sheet metal part, and the volute 311 and the air guide plate 312 are foam parts with a low thermal conductivity, which can play a role in heat preservation. The hardness of the shell 330 is greater than the hardness of the foam part, and the shell 330 can protect the volute 311.

[0094] In some embodiments, a reinforcement structure 313 may be provided on the air guide plate 312. The hardness of the reinforcement structure 313 is greater than the hardness of the volute 311 and the air guide plate 312, that is, the structural strength of the reinforcement structure 313 is relatively large, so that the air guide plate 312 can be protected. When the air guide plate 312 is subjected to bending force or impact force, the reinforcement structure 313 can provide support and protection effects, so that the air guide plate 312 is not easily bent and broken, thereby protecting the air guide plate 312. The reinforcement structure 313 may be set as a plastic part or a metal part. The plastic part has a better thermal insulation effect, while the sheet metal part has a higher hardness and a better protective effect. The reinforcement structure 313 may also be set as other materials. It is necessary to ensure that the structural strength of the reinforcement structure 313 is greater than the structural strength of the foam.

[0095] In order to prevent the cold air in the inner cavity from contacting with the relatively high temperature indoor environment and thus generating condensed water, it can be understood that in the embodiment of the present invention, the bottom plate 110, the side plate 120, the panel 140 and the top cover 130 are respectively provided with a heat preservation layer. For example, in this embodiment, the heat preservation layer is a foam piece, and the foam piece can be foamed and molded according to the specific shape and size of the bottom plate 110, the side plate 120 and the top cover 130, so as to ensure that each foam piece can match its corresponding component.

[0096] It can be understood that in this embodiment, the insulation layer is arranged on the outside of the heat pump device 10, and a heat insulation barrier is formed by the insulation layer, thereby isolating the box body 100 from the indoor environment. Therefore, the temperature of the bottom plate 110, the side plate 120, the panel 140 and the top cover 130 will not rise with the higher indoor temperature, preventing the box body 100 from being affected by two air with large temperature differences at the same time. Even if the cold air in the inner cavity contacts the bottom plate 110, the side plate 120 and the top cover 130, it is not easy to generate condensation water, thereby reducing the possibility of condensation water generating on the outer surface of the box body 100.

[0097] Reference Fig.14 As shown, in the embodiment of the present invention, the insulation layer of the bottom plate 110 is the first insulation layer 113, and the first insulation layer 113 is arranged at the bottom plate 110. Specifically, in the present embodiment, the bottom plate 110 is a split structure, which includes a water receiving tray 111 and a support tray 112. The water receiving tray 111 and the support tray 112 are arranged along the height direction of the box body 100 assembly. The water receiving tray 111 is located on the upper side of the support tray 112, that is, the water receiving tray 111 is arranged on the relatively inner side, and it is in direct contact with the cold air in the inner cavity, so the temperature of the water receiving tray 111 is relatively low. Correspondingly, the support tray 112 is arranged on the relatively outer side, and it is in direct contact with the indoor environment, so the temperature of the support tray 112 is relatively higher.

[0098] In one example, the water receiving tray 111 is a metal part, and the support tray 112 is a plastic part. In order to block the water receiving tray 111 from transferring cold to the support tray 112, in this embodiment, the first thermal insulation layer 113 is arranged between the water receiving tray 111 and the support tray 112, thereby separating the water receiving tray 111 and the support tray 112, and blocking the water receiving tray 111 from transferring cold to the support tray 112. Specifically, the upper surface of the first thermal insulation layer 113 is adapted to the lower end surface of the water receiving tray 111, so that the first thermal insulation layer 113 can cover the lower end surface of the water receiving tray 111; the lower surface of the first thermal insulation layer 113 is adapted to the upper end surface of the support tray 112, so that the first thermal insulation layer 113 can cover the upper end surface of the support tray 112.

[0099] Reference Fig.14As shown, in the embodiment of the present invention, in order to improve the water collecting capacity of the water receiving tray 111 and reduce the risk of water leakage from the edge of the water receiving tray 111, the outer periphery of the water receiving tray 111 is provided with a first peripheral edge 1121, and the first peripheral edge 1121 protrudes upward from the upper surface of the water receiving tray 111, thereby preventing water from overflowing. The outer periphery of the support plate 112 protrudes upward to form a second peripheral edge 1121, and the second peripheral edge 1121 and the upper surface of the support plate 112 define a receiving groove 1122. In order to reduce the contact between the first peripheral edge 1121 and the second peripheral edge 1121, the outer periphery of the first thermal insulation layer 113 is provided with a third peripheral edge 1131, and the third peripheral edge 1131 is located between the first peripheral edge 1121 and the second peripheral edge 1121, thereby separating the first peripheral edge 1121 and the second peripheral edge 1121, avoiding direct contact between the first peripheral edge 1121 and the second peripheral edge 1121, and blocking the cold transfer from the water receiving tray 111 to the support plate 112.

[0100] In order to achieve the connection between the water receiving tray 111, the first insulation layer 113 and the support tray 112, in the embodiment of the present invention, the bottom tray 110 further includes a plurality of connectors, and the connectors may be provided with 4, 5, 6, etc., and the plurality of connectors are evenly arranged on the water receiving tray 111, and the connectors are arranged at intervals. In one example, there are 4 connectors, and the 4 connectors are respectively arranged at positions close to the edge of the water receiving tray 111, so as to minimize the contact between the connectors and the cold air in the inner cavity.

[0101] In the embodiment of the present invention, along the direction from the water receiving tray 111 to the support tray 112, the connecting piece is sequentially arranged through the water receiving tray 111, the first insulation layer 113 and the support tray 112. In one example, one end of the connecting piece is connected to the water receiving tray 111, and the other end extends downward and protrudes from the lower end surface of the water receiving tray 111. When assembling the chassis 110, it is only necessary to insert the first insulation layer 113 and the support tray 112 into the connecting piece in sequence to complete the assembly, which reduces the difficulty of assembling the chassis 110.

[0102] In the embodiment of the present invention, one end of the connecting piece is fixedly connected to the water receiving pan 111, and the other end is fixedly connected to the support pan 112. The water receiving pan 111 and the support pan 112 are indirectly connected through the connecting piece, thereby clamping the first thermal insulation layer 113, and improving the overall structural stability of the chassis 110. It should be noted that the connecting piece can be welded to the water receiving pan 111, or connected to the water receiving pan 111 through a fastener; the connecting piece and the support pan 112 can be connected through a fastener or a buckle, which is not limited in this embodiment.

[0103] It can be understood that, in the embodiment of the present invention, the water receiving tray 111 and the support tray 112 are connected only by connecting parts, which not only ensures that the first insulation layer 113 can be firmly clamped between the water receiving tray 111 and the support tray 112, and continuously maintains the interval between the water receiving tray 111 and the support tray 112, but also effectively reduces the direct contact area between the water receiving tray 111 and the support tray 112, minimizes the connection between the water receiving tray 111 and the support tray 112, and further reduces the possibility of transferring cold from the water receiving tray 111 to the support tray 112.

[0104] Reference Fig.14 As shown, in the embodiment of the present invention, the central position of the water receiving tray 111 is recessed to form a water collecting tank 1111 for collecting water. In order to prevent the connector from being soaked in condensed water for a long time, in the present embodiment, along the height direction of the box body 100 assembly, the upper end of the connector is configured to be higher than the water collecting tank 1111, which not only reduces the risk of the connector being soaked in condensed water and corroded, and prolongs the service life of the connector, but also prevents condensed water from flowing along the connector, specifically, prevents condensed water from penetrating into the first thermal insulation layer 113, reduces the risk of condensed water corroding the first thermal insulation layer 113 and causing its thermal insulation performance to decrease, and also prevents condensed water from flowing to the support plate 112 and lowering the temperature of the support plate 112, thereby reducing the possibility of causing additional condensed water to be generated.

[0105] Reference Fig.15 As shown, in the embodiment of the present invention, the chassis 110 further includes a plurality of foot pads 115, and the number of the foot pads 115 is consistent with the number of the connecting members, based on which, the foot pads 115 and the connecting members are arranged in a one-to-one correspondence. Specifically, the foot pads 115 are arranged on the lower side of the support plate 112, one end of the connecting member is fixedly connected to the water receiving tray 111, and the other end protrudes from the lower end surface of the support plate 112, based on which, the foot pads 115 are connected to one end of the connecting member protruding from the support plate 112. When the foot pads 115 are connected to the connecting member, they can abut against the support plate 112, and the plurality of foot pads 115 can cooperate to support the chassis 110.

[0106] In one example, the foot pad 115 is made of rubber material, which can be directly placed on the indoor floor, or installed on a support structure such as a bracket. It is understandable that the provision of the foot pad 115 can prevent the chassis 110 from transferring cold to the indoor floor or the support structure on which it is installed.

[0107] It should be noted that the chassis 110 is provided with a water inlet 116 and a water outlet 117. The water inlet 116 is connected to the water inlet pipe 520, and the water outlet 117 is connected to the water outlet pipe 530. The water outlet 117 is used for external piping to supply hot water for domestic hot water and space heating. Since the bottom side of the chassis 110 has four foot pads 115, the body can be raised to protect the water inlet 116 and the water outlet 117, avoiding damage to the water inlet 116 and the water outlet 117 when the whole machine is directly placed on the ground during transportation.

[0108] Reference Fig.16 As shown, the insulation layer of the top cover 130 is a second insulation layer 135, which is arranged on the lower side of the top cover 130 and covers the lower end surface of the top cover 130, thereby separating the top cover 130 from the inner cavity and preventing the cold air in the inner cavity from directly contacting the top cover 130. In order to match the top cover 130, the second insulation layer 135 is provided with two through slots 1351 in parallel, and the two through slots 1351 are respectively arranged corresponding to the air outlet 132 and the air outlet 132, one of the through slots 1351 is connected to the air inlet 131, and the other through slot 1351 is connected to the air outlet 132.

[0109] Specifically, in the embodiment of the present invention, the inner wall of the through groove 1351 and the upper end surface of the second thermal insulation layer 135 are transitionally connected via the step 1352. Correspondingly, the lower end surface of the top cover 130 is provided with two connecting parts corresponding to the two through grooves 1351, and the two connecting parts are annular structures protruding downward from the lower end surface of the top cover 130. Based on this, the cross section of the step 1352 is also annular. The connecting part is arranged through the through groove 1351 and is at least partially located on the step 1352. In an example, the lower end surface of the connecting part is in contact with the upper end surface of the step 1352.

[0110] The lower end surface of the top cover 130 protrudes downward to form a plurality of positioning posts, which are arranged at intervals. Correspondingly, the upper end surface of the second thermal insulation layer 135 is recessed downward to form a plurality of positioning grooves 1353, which are arranged corresponding to the positioning posts, wherein the positioning posts are inserted into the positioning grooves 1353 and are interference-fitted with the positioning grooves 1353, thereby achieving a fixed connection between the top cover 130 and the second thermal insulation layer 135.

[0111] In one example, there are four positioning posts, and the top cover 130 is in the shape of a square plate as a whole. Based on this, the four positioning posts can be arranged near the four corners of the top cover 130, so as to disperse the connection stress and further enhance the stability of the connection. It can be understood that, compared with the connection method relying on fasteners, the interference fit between the positioning posts and the positioning grooves 1353 not only simplifies the assembly process of the second thermal insulation layer 135, but also minimizes the heat exchange between the top cover 130 and the cold air in the inner cavity, thereby improving the thermal insulation performance of the second thermal insulation layer 135.

[0112] In some embodiments, the thermal insulation layer further includes a thermal insulation member 136 , and the thermal insulation member 136 matches the shape of the upper side of the top cover 130 .

[0113] Specifically, refer to Fig.16 As shown, the heat-insulating member 136 includes a fitting portion 1361 and two surrounding portions 1362, wherein the fitting portion 1361 is a plate-like structure, which fits the upper end surface of the top cover 130. It should be noted that in this embodiment, the fitting portion 1361 may completely cover the upper end surface of the top cover 130, or may only cover part of the upper end surface of the top cover 130 based on the appearance requirements, which is not limited in this embodiment.

[0114] The two surrounding portions 1362 are spaced apart from each other on the fitting portion 1361 and penetrate the fitting portion 1361. The surrounding portion 1362 can be arranged to enclose a slot for the air guide ring 133 to pass through, and the air guide ring 133 is inserted into the slot. It can be understood that the surrounding portion 1362 is wrapped around the outside of the air guide ring 133, and the surface of the upper end surface of the top cover 130 close to the air guide ring 133 is covered with the fitting portion 1361. Therefore, the heat preservation member 136 can reduce the heat exchange between the cold air flowing through the air inlet 131 and the air outlet 132 and the indoor environment, thereby reducing the possibility of condensation water on the upper side of the top cover 130.

[0115] Reference Fig.17 As shown, in an embodiment of the present invention, the insulation layer of the side panel 120 is a third insulation layer 121, and the third insulation layer 121 is arranged on the inner side of the side panel 120, which covers the inner surface of the side panel 120, and a second filling layer (not shown in the figure) is filled between the third insulation layer 121 and the side panel 120. It can be understood that the third insulation layer 121 can separate the side panel 120 from the inner cavity, blocking the cold air in the inner cavity from directly contacting the side panel 120. In this embodiment, the second filling layer can be adhesive or sponge, which is not limited in this embodiment. The provision of the second filling layer can fill the gap between the inner surface of the side panel 120 and the third insulation layer 121, thereby improving the sealing between the side panel 120 and the third insulation layer 121, and further improving the insulation performance of the third insulation layer 121.

[0116] Reference Fig.18As shown, in an embodiment of the present invention, the insulation layer of the panel 140 is a fourth insulation layer 141, and the fourth insulation layer 141 is arranged on the inner side of the panel 140, which covers the inner surface of the panel 140, and a third filling layer (not shown in the figure) is filled between the fourth insulation layer 141 and the panel 140. It can be understood that the fourth insulation layer 141 can separate the panel 140 from the inner cavity, blocking the cold air in the inner cavity from directly contacting the panel 140. In this embodiment, the third filling layer can be adhesive or sponge, which is not limited in this embodiment. The provision of the third filling layer can fill the gap between the inner surface of the panel 140 and the fourth insulation layer 141, thereby improving the sealing between the panel 140 and the fourth insulation layer 141, and further improving the insulation performance of the fourth insulation layer 141.

[0117] Reference Fig.17 As shown, in the embodiment of the present invention, the box body 100 assembly further includes a bracket 160, wherein the bracket 160 is disposed on the inner side of the side plate 120, and the third thermal insulation layer 121 is disposed between the bracket 160 and the side plate 120. In the present embodiment, a first mounting portion 161 is disposed on the upper side of the bracket 160, and the upper end of the side plate 120 is fixedly connected to the first mounting portion 161. It should be noted that the side plate 120 and the first mounting portion 161 may be connected by fasteners, may be connected by welding, or may be connected by other types of fixed connection methods, which is not limited in the present embodiment.

[0118] In this embodiment, a second mounting portion 162 is provided on the lower side of the bracket 160, and the lower end of the side plate 120 is fixedly connected to the second mounting portion 162. It should be noted that the side plate 120 and the second mounting portion 162 can be connected by fasteners, welding, or other types of fixed connection methods, which are not limited in this embodiment. It can be understood that in this embodiment, the side plate 120 is connected to the first mounting portion 161 and the second mounting portion 162 respectively, thereby clamping the third thermal insulation layer 121, thereby improving the stability of the overall structure.

[0119] Considering that both the first mounting portion 161 and the second mounting portion 162 are directly exposed to the cold air in the inner cavity, the first mounting portion 161 and the second mounting portion 162 will transfer cold air to the side plate 120, thereby causing condensed water to be generated on the surface of the side plate 120. To this end, in the embodiment of the present invention, a baffle is formed on the lower end surface of the third thermal insulation layer 121. The baffle is arranged along the circumference of the side plate 120, and is located on the side of the first mounting portion 161 facing the inner cavity, and is fitted with the first mounting portion 161, thereby separating the first mounting portion 161 from the inner cavity, and preventing the cold air in the inner cavity from directly contacting the first mounting portion 161.

[0120] The embodiment of the present invention also provides a hot water heating system, including the heat pump device 10 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, providing users with domestic hot water and heating hot water.

[0121] Since the hot water heating system adopts all the technical solutions of the heat pump device 10 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.
