[0049] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0050] In the description of the present application, it should be understood that, in relation to the orientation description, for example, the orientation or position relationship indicated by up, down and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation of the present application, and therefore cannot be understood as a limitation of the present application.

[0051] In the description of the present application, if there is a description of first, second, only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0052] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting and the like should be broadly understood, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0053] In the related art, in order to save installation space, some heat pump water heaters integrate the refrigerant circulation loop and the water flow pipeline on an all-in-one machine, also known as an integrated heat pump device, which is connected with the indoor through a water pipe to supply the heat demand of domestic hot water and space heating. The electric control box, refrigerant circulation loop and water flow pipeline and other components are arranged in the same space, and the internal structure layout is relatively compact. The electric control box of the heat pump device is located below the top cover and above the middle partition, so that the maintenance of the electric control box needs to disassemble the front panel, the top cover and the left and right side plates, then loosen the fixing bolts of the electric control box and the middle partition, and then start disassembling the electric control box body, which has the problem of inconvenient maintenance of internal parts. Moreover, most of the waterway parts are blocked by the electric control box, which requires a large amount of side space for maintenance.

[0054] Some heat pump products adopt an integrated shell, and when maintenance is required, the entire shell is first removed, and then the electric control box is disassembled, so that the internal parts can be maintained. The operation is relatively cumbersome, and many parts are located on both sides of the machine body, which is difficult to directly maintain from the front side of the machine body, and needs to be accessed to the both sides of the machine body for maintenance, and a maintenance space needs to be reserved on both sides of the machine body.

[0055] Therefore, the overall heat pump equipment in the related art has certain requirements for the installation environment, and requires a certain installation and maintenance space in the top or left-right direction, thereby occupying the limited space in the room and limiting the installation scene. In addition, since the evaporator needs to exchange heat with the outdoor environment, the heat pump equipment needs to be installed in the outdoor environment. Once the waterway and other parts fail and need to be maintained, complex steps are required to complete the disassembly and maintenance, which will cause the cost to rise. Especially for residents on higher floors, installation and maintenance need to be operated in the outdoor high-altitude environment, which not only has high installation and maintenance costs, but also brings high risks to the installation process.

[0056] Therefore, the embodiment of the present application proposes a heat pump equipment 10, which adopts a flip type electric control box structure, can realize quick operation to expose the internal parts, and is convenient for maintenance of the internal parts. The heat pump equipment 10 is described below with specific embodiments.

[0057] Referring to Figure 1 and Figure 2 , the heat pump equipment 10 of the embodiment of the present application comprises a box body 100, a heat pump assembly 200 and a fan 300. The box body 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 box body 100 is provided with an opening 103 and a panel (not shown in the figure). The opening 103 is in communication with the inner cavity, and the panel is detachably installed at the opening 103. The opening 103 is located on the front side of the box body 100, and the opening 103 can be opened or closed through the panel. In some embodiments, the panel and the box body 100 can be connected through buckles, screws or locks, or can be rotatably connected with the box body 100 through a hinge or a hinge structure.

[0058] The heat pump assembly 200 comprises a compressor 210, a first heat exchanger 220, a second heat exchanger 230 and a throttling component. The first heat exchanger 220 is arranged at a middle position of the inner cavity of the box body 100 and is vertically arranged along the height direction of the box body 100. The inner cavity of the box body 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.

[0059] In one embodiment, the first heat exchanger 220 is an evaporator 221, and the second heat exchanger 230 is a plate heat exchanger 231. The evaporator 221 is provided with a first refrigerant pipeline 240, and the plate heat exchanger 231 is provided with a second refrigerant pipeline 250 and a water pipeline 2311. The plate heat exchanger 231 is connected to the compressor 210 and the throttling device through the second refrigerant pipeline 250, and the evaporator 221 is connected to the compressor 210 and the throttling device through the first refrigerant pipeline 240, forming a refrigerant circulation loop for refrigerant circulation.

[0060] Reference Figure 2 As shown, the heat pump device 10 also includes a piping assembly 500, which is installed inside the air inlet chamber 101. The piping assembly 500 includes a water pump 510, an inlet pipe 520, and an outlet pipe 530. The inlet pipe 520 and the outlet pipe 530 are respectively connected to the water flow pipe 2311. The water pump 510 can be installed on either the inlet pipe 520 or the outlet pipe 530 to form a water supply pipe. During operation, the refrigerant output from the compressor 210 passes through the plate heat exchanger 231, where it exchanges heat with water. After throttling, it enters the evaporator 221, where it exchanges heat with air. Then, it returns to the compressor 210 to begin the next cycle. The water pump 510 drives cold water into the plate heat exchanger 231, allowing the water to exchange heat with the refrigerant, thereby producing hot water.

[0061] It should be noted that, referring to Figure 1 As shown, the top of the housing 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 positioned facing the evaporator 221, and the air outlet of the fan 300 is connected to the air outlet 132. Air inlet 131 and air outlet 132 are each provided with a duct connector 133. Air inlet 131 is connected to an air inlet pipe via the duct connector 133, and air outlet 132 is connected to an air outlet pipe via the duct connector 133. Both the air inlet and air outlet pipes are connected to the outdoor environment. Outdoor air enters the air inlet chamber 101 through the air inlet pipe and air inlet 131, exchanges heat with the evaporator 221, and then enters the air outlet chamber 102. Finally, it is discharged to the outdoor environment through the air outlet 132 and air outlet pipe. By using outdoor air as a heat source and extracting heat through a heat exchange process, hot water is heated. Figure 1 The direction indicated by the middle arrow is the direction of air intake and exhaust.

[0062] It can be understood that the heat pump equipment 10 of the embodiment of the utility model can provide hot water through the water outlet pipe 530, which is used for supplying domestic hot water and heating hot water, and the water outlet pipe 530 can also be connected with a water tank to store hot water in the water tank for users to use. The water inlet of the water inlet pipe 520 and the water outlet of the water outlet pipe 530 are arranged on the bottom plate 110 of the box body 100, so as to avoid affecting the appearance structure from the visual area on the front or side.

[0063] The heat pump equipment 10 is installed in an indoor environment, and can be installed in a basement, an attic, a garage, a machine room, a utility room and the like, so that the installation scene is rich, and the heat pump equipment 10 does not need to be installed in an outdoor environment, thereby saving high installation cost, long installation time and high installation risk and the like caused by installation of an outdoor unit, and the installation scene is not limited by appearance of a building, installation regulations and outdoor noise; the whole installation and maintenance process is operated indoors, so that the installation and maintenance cost is low, and the operation is simple; the heat pump equipment 10 is not affected by a severe outdoor environment during shutdown, a large amount of redundancy does not need to be designed for anti-freezing and ice design of a water supply pipeline, and manufacturing cost is reduced.

[0064] Referring to Figure 1 and Figure 2 It can be understood that the heat pump equipment 10 of the embodiment further comprises an electric control box 400, the electric control box 400 is used for electrically connecting the compressor 210, the fan 300, the water pump 510, functional components and the like, the functional components comprise sensors, control valves and the like, and the electric control box 400 can also be connected with external components of the heat pump equipment 10, for example, a water tank can be provided with a switch valve, the electric control box 400 can lead out a line and extend to the outside of the box body 100, so that the line is connected with the switch valve, and control of the switch valve is realized.

[0065] The electric control box 400 is connected at the opening 103 of the box body 100, and specifically, the electric control box 400 is rotatably connected with the box body 100, for example, the electric control box 400 is connected with the box body 100 in a hinged manner, so that the electric control box 400 can rotate around the hinged position, and the electric control box 400 is flipped, so that the electric control box 400 can be rotated towards the direction of the air inlet cavity 101, and is moved into the air inlet cavity 101 from the opening 103, so that the electric control box 400 is stored in the box body 100; or the electric control box 400 can be flipped towards the outside of the box body 100 when the electric control box 400 is located in the air inlet cavity 101, so that the electric control box 400 is moved out of the air inlet cavity 101 from the opening 103.

[0066] It can be understood that the electric control box 400 is approximately cuboid in the embodiment, and since the electric control box 400 is arranged at the position close to the opening 103 of the air inlet cavity 101, the electric control box 400 can cover the air inlet cavity 101 at the opening 103, and the compressor 210, the plate heat exchanger 231, the first refrigerant pipeline 240, the second refrigerant pipeline 250, the water inlet pipe 520, the water outlet pipe 530 and the water pump 510 and the like are arranged in the air inlet cavity 101, and the electric control box 400 is arranged at the position close to the opening 103 of the air inlet cavity 101, so that the electric control box 400 can cover the air inlet cavity 101 at the opening 103. Figure 2As shown, in some embodiments, the compressor 210 is arranged close to the back of the cabinet 100, the plate heat exchanger 231 is fixedly connected to the side wall of the cabinet 100, the water pump 510 is located below the plate heat exchanger 231, the first refrigerant pipeline 240, the second refrigerant pipeline 250 and the water flow pipeline 2311 are arranged according to the positions of the above components, the above components can be shielded by the electric control box 400, and then the panel covers the opening 103, so that the internal structure of the cabinet 100 can be shielded.

[0067] Referring to Figure 2 As shown, when the heat pump equipment 10 needs to be overhauled, the panel is only opened, the electric control box 400 is flipped around the hinge position, the electric control box 400 is moved out of the air inlet cavity 101, the air inlet cavity 101 is opened, the compressor 210, the second heat exchanger 230 and the pipeline assembly 500 are exposed, that is, the user can see the internal pipeline assembly 500 and the refrigerant circulation loop at the front side of the cabinet 100, which is convenient for production, installation, debugging, maintenance and the like, and replacement of parts, without the need to disassemble the electric control box 400; in addition, after the electric control box 400 is moved out of the air inlet cavity 101, wiring and maintenance of the electric control box 400 are also facilitated, which is simple and fast in operation and effectively improves work efficiency.

[0068] Considering that the water supply pipeline is more prone to failure than the refrigerant pipeline, in an embodiment, the pipeline assembly 500 is arranged close to the opening 103 of the air inlet cavity 101, that is, along the front-rear direction of the cabinet 100, the pipeline assembly 500 is arranged in front of the refrigerant pipeline and the compressor 210, which is more convenient for overhauling the pipeline assembly 500.

[0069] It should be noted that the fan 300 is located in the air outlet cavity 102 and is arranged in a spaced manner with the air inlet cavity 101, so that the fan 300 can be exposed after the panel is opened, and the fan 300 is convenient for maintenance. In some embodiments, the fan 300 can be connected to the cabinet 100 by a guide rail structure, so that the fan 300 can be moved out of the air outlet cavity 102 along the guide rail structure, which is more convenient for maintenance. The heat pump equipment 10 adopts the layout structure of the above embodiment, has small space requirements, does not need to reserve a large amount of installation and maintenance space on both sides of the machine body, and all maintenance can be completed at the front side of the cabinet 100, which is convenient for operation.

[0070] Referring to Figure 1 and Figure 2 As shown, the cabinet 100 includes a bottom disc 110, a side plate 120, a top cover 130 and a panel, the side plate 120 defines the opening 103, the bottom disc 110 and the top cover 130 are connected to the upper and lower ends of the side plate 120 respectively, and the inner cavity can be defined by the bottom disc 110, the side plate 120, the top cover 130 and the panel. The air inlet 131 and the air outlet 132 are arranged on the top cover 130.

[0071] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the control box 400 is rotatably connected to the side plate 120 via a hinge structure 600. The hinge position is located on the right side of the opening 103, allowing the control box 400 to flip to the right to move out of the air inlet cavity 101. The hinge structure 600 can be a hinge, a hinge, or a similar structure. Taking a hinge as an example, two hinges can be connected to both ends of the control box 400 along its height direction, and both hinges are connected to the side plate 120, thus enabling the control box 400 to flip.

[0072] Of course, the control box 400 is not limited to being hinged to the side panel 120. It 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 control box 400 is hinged to the top cover 130 and can be flipped upward to open the air inlet cavity 101; or the lower end of the control box 400 is hinged to the chassis 110 and can be flipped downward to open the air inlet cavity 101.

[0073] Reference Figure 3 and Figure 5 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 electrical control box 400, and the second hinge 620 is fixedly connected to the edge of the side plate 120. The first hinge 610 is provided with a bushing 611, and the bushing 611 is provided with a shaft hole. The second hinge 620 is provided with a hinge shaft 621, which is inserted into the shaft hole, so that the first hinge 610 and the second hinge 620 can rotate relative to each other, thereby realizing the rotation of the electrical control box 400 around the hinge shaft 621.

[0074] by Figure 5 The example shown illustrates that, since the bushing 611 and the hinge shaft 621 are connected by a sleeve connection, the bushing 611 can move upward to disengage from the hinge shaft 621, thereby separating the first hinge 610 and the second hinge 620. This allows for the disassembly and separation of the electrical control box 400 from the housing 100, facilitating the installation and removal of the electrical control box 400. In some other embodiments, the hinge shaft 621 can be provided on the first hinge 610, and the bushing 611 can be provided on the second hinge 620, which also allows for the disassembly and separation of the first hinge 610 and the second hinge 620.

[0075] Reference Figure 1 and Figure 4As shown, in order to fix the electric control box 400, in some embodiments, the right side of the electric control box 400 is connected with the side plate 120 through the hinge structure 600 described above, and the left side of the electric control box 400 is provided with a lug 4221 arranged 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 4221 is connected with the top cover 130 to fix the electric control box 400. Specifically, the lug 4221 and the top cover 130 are respectively provided with connecting holes 134, and the electric control box 400 is fixed by using a bolt to pass through the connecting holes 134 of the lug 4221 and the top cover 130, so as to avoid swinging of the electric control box 400 during use.

[0076] It can be understood 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 4221 is not limited to being connected with the top cover 130 by the bolt, and exemplarily, the lug 4221 can be provided with a buckle, and the top cover 130 is provided with a clamping groove matched with the buckle, so as to realize quick fixing by clamping.

[0077] In addition, when the electric control box 400 is close to the bottom plate 110, the lug 4221 can be arranged at the lower end of the electric control box 400, and the lug 4221 is connected with the bottom plate 110 by a bolt or a clamping manner. The specific shape of the lug 4221 can be selected according to actual requirements of the product to meet the requirements of connection with the top cover 130 or the bottom plate 110.

[0078] Referring to Figure 6 As shown, the electric control box 400 includes an electric control board 410, a box body 420 and a box cover 430, the box body 420 is connected with the box cover 430 to form an installation cavity, the electric control board 410 is arranged in the installation cavity and connected with the box body 420, the box body 420 plays a role of fixing the electric control board 410, and the electric control board 410 is protected by being wrapped by the box body 420 and the box cover 430. In some embodiments, a sealing element is arranged between the box body 420 and the box cover 430, so as to improve the sealing performance of the electric control box 400 as a whole and improve the reliability.

[0079] The electric control board 410 is provided with electric control elements and wiring terminals 412, which are distributed on the side of the electric control box 400 facing the box cover 430. The wiring terminals 412 are electrically connected to the compressor 210, the fan 300, the water pump 510, sensors, control valves and other components through wires 460. In the embodiment, when the electric control box 400 is moved into the cabinet 100, the box cover 430 faces the air inlet cavity 101. When the electric control box 400 is moved out of the cabinet 100, the box cover 430 can face the front of the cabinet 100. After opening the box cover 430, the electric control board 410 can be conveniently wired and repaired. Therefore, in the embodiment, the hinge structure 600 is connected to the box body 420. After the electric control box 400 is flipped and moved out of the cabinet 100, the box cover 430 can be opened while the box body 420 remains connected to the cabinet 100, facilitating wiring and repair operations.

[0080] In some embodiments, the box cover 430 can be connected to the box body 420 by a snap-fit method, facilitating opening of the box cover 430. In other embodiments, the box cover 430 can be connected to the box body 420 by bolts or other methods.

[0081] Referring to Figure 6 As shown in the figure, the box body 420 includes a back plate 421 and a first housing 422. The back plate 421 is connected to the electric control board 410, and the electric control board 410 can be fixed to the back plate 421 by a snap-fit or screws. The first housing 422 covers the side of the back plate 421 away from the electric control board 410. The box cover 430 includes a cover plate 431 and a second housing 432. The cover plate 431 is connected to the back plate 421, and a mounting cavity is formed between the cover plate 431 and the back plate 421. The second housing 432 covers the side of the cover plate 431 away from the electric control board 410. The first housing 422 and the second housing 432 are both metal housings, and the back plate 421 and the cover plate 431 are both insulating members. The first housing 422 is used to protect the back plate 421, and the second housing 432 is used to protect the cover plate 431. The cover plate 431 and the back plate 421 form an inner plastic housing, and the first housing 422 and the second housing 432 form an outer metal housing, effectively protecting the electric control board 410.

[0082] It should be noted that the outer metal housing can provide support for the entire electric control box 400. In an embodiment, the first hinge 610 is connected to the first housing 422, and the connection structure has higher strength, ensuring that the connection between the electric control box 400 and the cabinet 100 is more reliable. After the electric control box 400 is flipped and moved out of the cabinet 100, the box cover 430 can be opened, and the operation is simple and convenient.

[0083] Since the electric control element of the electric control board 410 includes a first heating device, which can be a rectifier bridge, an intelligent power module, an insulated gate bipolar transistor, etc., the electric control board 410 is further provided with a heat sink 440 in the embodiments. The heat sink 440 is arranged on the side of the electric control board 410 facing the box cover 430 and abuts against the heating surface of the first heating device. The heat sink 440 can take away the heat of the first heating device. The heat sink 440 can be a fin heat sink. The heat sink 440 can also contact two or more first heating devices at the same time to dissipate heat. For example, the rectifier bridge and the intelligent power module are arranged adjacent to each other. The heat sink 440 contacts 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.

[0084] Referring to Figure 6 The box cover 430 is provided with a through hole 4301. The size of the through hole 4301 matches the size of the heat sink 440, so that the heat sink 440 can pass through the through hole 4301, and at least part of the heat sink 440 is exposed outside the box cover 430. Since the box cover 430 includes the cover plate 431 and the second housing 432, the cover plate 431 and the second housing 432 are both provided with the through hole 4301 in the embodiments, so that the heat sink 440 can pass through the cover plate 431 and the second housing 432 at the same time.

[0085] Referring to Figure 7 and Figure 9 In some embodiments, a sealing ring 441 is arranged between the heat sink 440 and the box cover 430. Part of the structure of the heat sink 440 is exposed from the through hole 4301. The heat sink 440 is provided with a flange along the outer periphery of the side facing the electric control board 410. The sealing ring 441 is arranged around the heat sink 440 and abuts against the flange on one side. When the box cover 430 is assembled with the box body 420, the box cover 430 abuts against the other side of the sealing ring 441 and presses the sealing ring 441 tightly, so as to fix the sealing ring 441 and improve the sealing performance between the heat sink 440 and the box cover 430, thereby improving the overall sealing performance of the electric control box 400.

[0086] It can be understood that when the electric control box 400 is located in the air inlet cavity 101, the box cover 430 and the heat sink 440 both face the air inlet cavity 101, and the side of the box body 420 away from the electric control board 410 faces the front of the cabinet 100. When the heat pump equipment 10 is working, the air in the outdoor environment enters the air inlet cavity 101 and flows along the air inlet cavity 101 to the evaporator 221. Part of the airflow passes through the heat sink 440, thereby helping to improve the heat dissipation efficiency of the heat sink 440.

[0087] In some embodiments, referring to Figure 2 and Figure 3As shown, the heat sink 440 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 heat sink 440 is arranged close to the air inlet 131, which is more conducive to the airflow flowing through the heat sink 440, and the heat dissipation effect is better. It should be noted that the airflow takes away the heat of the heat sink 440 and then exchanges heat with the evaporator 221, which can recover the heat taken away by the airflow and improve the heating efficiency.

[0088] The electric control element, the wiring terminal 412 and the heat sink 440 are arranged on the side of the electric control board 410 facing the box cover 430, which can facilitate heat dissipation of the heat sink 440 on the one hand, and facilitate wiring of the wiring terminal 412 on the other hand, while ensuring that the wiring and the heat sink 440 are located on the same side of the electric control board 410, without the need for special production process, facilitating production and manufacturing.

[0089] In addition, the electric control box 400 is provided with a wiring seat 450, which is used for connecting external power lines, signal lines, temperature sensing bag lines and the like. The wiring seat 450 is used for connecting the above-mentioned lines to the electric control board 410, and the wiring seat 450 is arranged below the electric control board 410, and part of the wiring terminal 412 of the electric control board 410 is electrically connected to the wiring seat 450 through an internal adapter line.

[0090] Specifically as shown in the figure, Figure 3 As shown, the electric control box 400 is turned over to the outside of the box body 100 and the box cover 430 is opened, the wiring terminal 412 of the electric control board 410 and the wiring led out by the wiring seat 450 are on the same side, the signal line, the power line and the temperature sensing bag line are all connected to the inside of the electric control box 400 from the bottom area of the electric control box 400, and are inserted into the corresponding wiring seat 450 or wiring terminal 412.

[0091] It should be noted that the electric control element also includes a second heating device 411, which is a device using a non-encapsulated structure, which generates heat when working, and needs to be provided with waterproof protection measures, therefore, in some embodiments, the second heating device 411 is arranged in the electric control box 400, and an air duct 401 is arranged on the electric control box 400, which is used for dissipating heat of the second heating device 411. The second heating device 411 can be an inductor 4111 or other heating device.

[0092] The inductor 4111 is taken as an example for description. The inductor 4111 is arranged on the side of the electric control box 400 facing the box cover 430. The air duct 401 is formed on the box cover 430. The box cover 430 is provided with the air inlet 402 and the air outlet 403 which are communicated with the air duct 401 respectively. The air inlet 402 is arranged towards the radiator 440. The air outlet 403 is arranged on the side wall of the box cover 430. When the electric control box 400 is turned over into the air inlet cavity 101, the air outlet 403 is arranged towards the evaporator 221. At least part of the structure of the inductor 4111 is located in the air duct 401.

[0093] When the heat pump equipment 10 works, the air in the outdoor environment enters the air inlet cavity 101 and flows to the evaporator 221 along the air inlet cavity 101. Part of the airflow enters the air duct 401 through the air inlet 402 after passing through the radiator 440 and flows to the inductor 4111 along the air duct 401, and then is discharged through the air outlet 403. It should be noted that since the evaporator 221 is close to the air outlet 403 of the air duct 401, the airflow in the air inlet cavity 101 accelerates the airflow speed discharged through the air outlet 403 when passing through the evaporator 221, thereby generating an air suction effect. Therefore, the airflow circulation of the inductor 4111 can be improved through the air duct 401. Moreover, since the air inlet 402 is arranged towards the radiator 440, the air speed passing through the radiator 440 can be accelerated, which is beneficial to improving the heat dissipation efficiency of the radiator 440.

[0094] Referring to Figure 7 The air duct 401 is formed on the box cover 430. Specifically, the cover plate 431 is made of plastic. The cover plate 431 is provided with a recess 4312 on the side away from the electric control board 410. The recess 4312 can be formed by one-piece injection molding. The cover plate 431 is provided with a convex portion 4311 on the side away from the electric control board 410. The cover plate 431 is provided with a through hole 4301 at the upper end. The convex portion 4311 is arranged adjacent to the through hole 4301. The convex portion 4311 is substantially square. The air inlet 402 is formed on the upper surface of the convex portion 4311. The air outlet 403 is formed on the right side of the convex portion 4311. The recess 4312 is formed on the surface of the convex portion 4311 away from the box body 420.

[0095] When the second shell 432 covers the cover plate 431, the air duct 401 is defined between the second shell 432 and the recess 4312. The second shell 432 is recessed on the side facing the cover plate 431 to form a cover body 4321 matched with the convex portion 4311, so that the second shell 432 can cover the cover plate 431. In addition, the second shell 432 is provided with an opening hole 4322 corresponding to the air inlet 402 and the air outlet 403, so as to form the air duct 401 on the box cover 430.

[0096] Referring to Figure 8 and Figure 9As shown, it should be noted that the side of the cover plate 431 facing the electric control board 410 is provided with a through slot, which is located on the bottom wall of the groove 4312. When the cover plate 431 covers the electric control board 410, the inductor 4111 can extend into the air duct 401 through the through slot, so that part of the structure of the inductor 4111 is located in the air duct 401.

[0097] The heat sink 440 and the air duct 401 are arranged in the height direction of the electric control box 400 from top to bottom, and the air inlet 402 of the air duct 401 is arranged towards the heat sink 440, that is, the air inlet 402 is arranged towards the top, and the airflow enters the air duct 401 from top to bottom. Considering that the electric control box 400 is close to the water supply pipeline, and there is a case that rainwater enters the air inlet 131 into the air inlet cavity 101.

[0098] Therefore, in some embodiments, referring to Figure 9 and Figure 10 As shown, the box cover 430 is provided with a first baffle 4313 and a second baffle 4314. The first baffle 4313 is arranged on one side of the air outlet 403 in the horizontal direction, and the second baffle 4314 is arranged in the air duct 401 and staggered with the first baffle 4313 in the vertical direction, forming an air guide channel 4011 in the air duct 401. It can be understood that since the air inlet 402 is arranged towards the top, by arranging the first baffle 4313 and the second baffle 4314 staggered at the air inlet 402, as Figure 10 As shown, the air guide channel 4011 is located between the air inlet 402 and the inductor 4111, and the first baffle 4313, the second baffle 4314 and the inductor 4111 are arranged in sequence from top to bottom. The first baffle 4313 covers part of the air inlet 402, the air guide channel 4011 extends downward from the air inlet 402, bends at the second baffle 4314 and extends towards the electric control board 410, and then bends downward again. That is, the air guide channel 4011 has a bending section, which can avoid the airflow from entering the air duct 401 directly from top to bottom, and has the effect of blocking the water flow from entering the air duct 401.

[0099] Referring to Figure 10 As shown, the arrow line P3 in the figure shows the direction of the airflow flowing along the air guide channel 4011. It can be understood that when the rainwater enters the air guide channel 4011 along with the airflow from the air inlet 402, the rainwater will fall on the second baffle 4314 due to the action of gravity, and the airflow will continue to flow along the air guide channel 4011, thereby separating the airflow and the water, effectively reducing the risk of the rainwater contacting the inductor 4111. In this way, the air duct 401 can not only dissipate heat for the inductor 4111, but also has a waterproof effect, improving the protection performance.

[0100] In an embodiment, the first baffle 4313 and the second baffle 4314 are both arranged on the cover plate 431 and are integrally formed with the cover plate 431, and the structure is firm and reliable. In order to have a better drainage effect, the second baffle 4314 is arranged downwardly inclined in a direction away from the inductor 4111, that is, a downwardly inclined inclined surface is formed, so that when the rainwater falls on the second baffle 4314, it can slide downwardly along the inclined surface, avoiding the rainwater flowing to the inductor 4111.

[0101] It can be understood that, as shown in Figure 10 In an embodiment, the second baffle 4314 can include a first plate body 4314a and a second plate body 4314b, the first plate body 4314a is arranged staggered with the first baffle 4313, the first plate body 4314a is arranged downwardly inclined, the second plate body 4314b is connected to one end of the first plate body 4314a away from the first baffle 4313, and the second plate body 4314b is arranged extending downwardly along the air duct 401,

[0102] Specifically, the second baffle 4314 is arranged opposite to the inductor 4111 in a direction perpendicular to the box cover 430 towards the box body 420, the projections of the first plate body 4314a and the second plate body 4314b cover the projection of the inductor 4111, so that after the rainwater falls on the first plate body 4314a, it flows downwardly along the first plate body 4314a, and then falls downwardly along the second plate body 4314b, avoiding the rainwater drained along the second baffle 4314 from contacting the inductor 4111, and further improving the waterproof effect.

[0103] As shown in Figure 7 It can be understood that the second baffle 4314 is located in the air duct 401 and is arranged opposite to the through slot in a direction of the cover plate 431 towards the electronic control board 410, the second baffle 4314 can effectively shield the inductor 4111 passing through the through slot, and it can also be understood that the second baffle 4314 can shield the through slot, and by combining the second baffle 4314 with the air guide channel 4011 structure, the airflow and the water can be effectively separated. The specific height of the second baffle 4314 can be set according to the size of the inductor 4111 to ensure that the second baffle 4314 can effectively shield the inductor 4111.

[0104] It should be noted that when the second shell 432 covers the cover plate 431, a gap can be formed between the inner wall of the second shell 432 and the second baffle 4314, facilitating the downward drainage of the water flow. As shown in Figure 9 Figure 9 The arrow line P1 inside the air duct 401 indicates the direction of the water flow.

[0105] ​In some embodiments, the second baffle 4314 is not limited to being arranged on the cover plate 431, and the second baffle 4314 can also be arranged on the side wall of the second shell 432 towards the cover plate 431, for example, the second baffle 4314 is arranged on the inner wall of the cover body 4321, and a drain port is formed between the second baffle 4314 and the inner wall of the cover body 4321.

[0106] Referring to Figure 9 As shown, considering that the air flow of the air inlet cavity 101 blows towards the electric control box 400, Figure 9 The direction indicated by the arrow line P2 outside the electric control box 400 is the direction of the external air flow. Therefore, in the embodiment of the utility model, the third baffle 4323 is arranged on the cover plate 431, the third baffle 4323 is arranged close to the air inlet 402, the air flow blown from the side towards the electric control box 400 is blocked by the third baffle 4323, and the risk of rainwater entering the air duct 401 is further reduced.

[0107] Referring to Figure 10 As shown, specifically, the third baffle 4323 is formed on the second shell 432 and is located at the top position of the cover body 4321, along the direction of the box cover 430 towards the box body 420, the third baffle 4323 and the first baffle 4313 are arranged on the opposite sides of the air inlet 402 in sequence, and the third baffle 4323 is arranged to extend towards the upper side, so as to be higher than the air outlet 403 and the first baffle 4313. In this way, the air flow blown from the side towards the electric control box 400 can be effectively blocked from directly entering the air duct 401 by the third baffle 4323, and the risk of rainwater entering the air duct 401 is reduced.

[0108] Therefore, in an embodiment, the box cover 430 blocks the air flow multiple times by arranging the first baffle 4313, the second baffle 4314 and the third baffle 4323 to change the flow direction, so as to be beneficial to separating rainwater from the air flow and greatly reducing the risk of rainwater contacting the inductor 4111. In the embodiment, the third baffle 4323 and the second shell 432 can be an integral molding structure, which is simple to manufacture, and the specific size of the third baffle 4323 can be set according to the size of the air inlet 402, so as to block the air inlet 402 along the direction of the box cover 430 towards the electric control board 410 and effectively block the rainwater.

[0109] Of course, the utility model is not limited to the above-mentioned implementation manners, and those skilled in the art can also make equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
