The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0048] In the description of the present application, it should be understood that, if the orientation description, such as the upper, lower, etc. Indicative orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, 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.

[0049] 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 indicative or implied relative importance or impliedly indicate the number of indicated technical features or impliedly indicate the order of the indicated technical features.

[0050] In the description of the utility model, unless otherwise explicitly defined, the words such as setting, installing, connecting should be understood in a broad sense, and the skilled person in the art can determine the specific meaning of the above words in the utility model in combination with the specific content of the technical scheme.

[0051] 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, the refrigerant circulation loop and the water flow pipeline 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 plate, 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 plate, and then the electric control box body can be disassembled, which has the problem of inconvenient maintenance of internal parts. Moreover, most of the waterway parts are blocked by the electric control box, and a large amount of side space is needed for maintenance.

[0052] Some other heat pump products adopt an integrated shell, which needs to be removed before the electric control box is disassembled, so that the internal parts can be maintained, which is also relatively cumbersome to operate, 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 to maintain, and also needs to reserve maintenance space on both sides of the machine body.

[0053] Therefore, the integrated heat pump device in the related art has certain requirements for the installation environment, and needs certain installation and maintenance space in the top or left and right directions, 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 device needs to be installed in the outdoor environment, and once the waterway parts fail and need to be maintained, complex steps are needed to complete the disassembly and maintenance, which will cause the cost to rise. Especially for the residents on higher floors, the installation and maintenance need to be operated in the outdoor high-altitude environment, which not only has high installation and maintenance cost, but also brings high risk to the installation process.

[0054] Therefore, the embodiment of the utility model provides a heat pump device 10, which adopts a flip type electric control box 400 structure, can realize quick operation to expose the internal parts, and is convenient for maintenance of the internal parts.

[0063] Specifically, the electric control box 400 is arranged at the opening 103 of the cabinet 100, and the electric control box 400 is rotationally connected with the cabinet 100, for example, the electric control box 400 is connected with the cabinet 100 in a hinged manner, so that the electric control box 400 can rotate around the hinged position to realize the overturning of the electric control box 400. In this way, the electric control box 400 can be rotated towards the air inlet cavity 101, moved into the air inlet cavity 101 from the opening 103, and stored in the cabinet 100; or the electric control box 400 can be overturned towards the outside of the cabinet 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.

[0064] It can be understood that the electric control box 400 in the embodiment is approximately cuboid, 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, 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.

The second hinge 620 is provided with a hinge shaft, which is inserted into the shaft hole. The first hinge 610 and the second hinge 620 can be relatively rotated, so that the electric control box 400 can be rotated around the hinge shaft.

[0073] Because the bushing and the hinge shaft are connected by a sleeve connection, the bushing can move upward to disengage from the hinge shaft, thereby separating the first hinge 610 and the second hinge 620, and realizing 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, a hinge shaft can be provided on the first hinge 610 and a bushing can be provided on the second hinge 620, which can also realize the disassembly and separation of the first hinge 610 and the second hinge 620.

[0074] Reference Figure 1 and Figure 2 As shown, in order to fix the electrical control box 400, in some embodiments, the right side of the electrical control box 400 is connected to the side plate 120 through the aforementioned hinge structure 600, and the left side of the electrical control box 400 is provided with a lug 423, which is located at the upper end of the electrical control box 400. When the electrical control box 400 is located in the air inlet cavity 101, it is connected to the top cover 130 through the lug 423, thereby fixing the electrical control box 400. Specifically, the lug 423 and the top cover 130 are respectively provided with connecting holes. Bolts are used to pass through the connecting holes of the lug 423 and the top cover 130 to fix the electrical control box 400 and prevent the electrical control box 400 from swinging during use.

[0075] Understandably, since the hinge structure 600 provides support and positioning for one side of the electrical control box 400, only one bolt is needed to fix the electrical control box 400 in this embodiment, improving 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 can be provided with a buckle, and the top cover 130 can be provided with a slot that matches the buckle, so as to achieve quick fixation through a snap-fit ​​method.

[0076] Furthermore, when the control box 400 is close to the chassis 110, the lug 423 can be installed at the lower end of the control box 400, and the lug 423 is connected to the chassis 110 by bolts or fasteners. The specific shape of the lug 423 can be selected according to the actual requirements of the product to meet the requirements for connection with the top cover 130 or the chassis 110.

[0077] The above are some examples of heat pump equipment 10. The following is a further explanation of the specific structure of the electrical control box 400.

[0078] In the related art, the inner terminal block and the outer terminal block in the heat pump water heater and the split air conditioner product are usually in a separate installation structure. Taking the heat pump water heater as an example, the inner terminal block of the outdoor unit is arranged in the electric control assembly, and the outer terminal block is arranged on the shell. The shell is provided with a wire outlet corresponding to the outer terminal block, and the wiring of the external equipment is led out of the wire outlet. However, for the whole heat pump equipment, the internal space is relatively compact, and the above scheme is not applicable. Moreover, the heat pump equipment 10 of the utility model is installed in an indoor environment. Since heat exchange with outdoor cold air is required, the internal temperature of the heat pump equipment 10 will be lower than the room temperature, and condensation phenomenon is easy to occur. The sealing and waterproof requirements of the electric control box 400 are relatively high. Therefore, the scheme of the related art is not applicable to the heat pump equipment 10 of the utility model.

[0079] Referring to Figure 5 , Figure 6 and Figure 7 , 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 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 containing 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 containing 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 containing 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.

[0080] Among them, the electric control board 410 is provided with an electric control element 411 and a plurality of terminal blocks 412. The electric control element 411 and the terminal block 412 are distributed on the side of the electric control box 400 facing the box cover. The terminal block 412 is electrically connected with the internal compressor 210, the fan 300, the water pump 510, the sensor, the control valve and other components, and can also be electrically connected with the external equipment, such as the gas wall-hanging stove, the electric heater or the water tank and other external equipment. It can be understood that the electric control box 400 also includes a wiring assembly. When the electric control board 410 is connected with the external equipment, part of the terminal block 412 of the electric control board 410 realizes electrical connection with the external equipment through the wiring assembly.

[0081] Specifically, the wiring assembly includes an inner wiring seat 450 and an outer wiring seat 460, wherein the inner wiring seat 450 is arranged in the first accommodating cavity 401, the inner wiring seat 450 is arranged side by side with the electric control panel 410, the outer wiring seat 460 is arranged in the second accommodating cavity 402, the inner wiring seat 450 and the wiring terminal 412 are electrically connected through the first wire 453, and the outer wiring seat 460 is provided with the second wire 463, the outer wiring seat 460 is led out of the electric control box 400 and the cabinet 100 through the second wire 463, and is connected with external equipment. The first wire 453 and the inner wiring seat 450 can be understood as an adapter circuit between the electric control panel 410 and the inner wiring seat 450, connected with external equipment through the second wire 463, realizing linkage with the gas wall-hanging stove, the electric heater or the water tank, and the second wire 463 can specifically include a temperature sensing bag, a control valve and other communication lines for connecting external equipment, and also includes a power line of the heat pump equipment 10.

[0082] It can be understood that the inner wiring seat 450 and the outer wiring seat 460 are the wiring assembly of the electric control panel 410 and the external equipment, and the inner wiring seat 450 and the outer wiring seat 460 are jointly installed in the electric control box 400, that is, the inner wiring seat 450 and the outer wiring seat 460 are integrated with the electric control box 400, without the need to separate the inner wiring seat 450 and the outer wiring seat 460 for installation, and the structure is more compact and saves installation space.

[0083] In some embodiments, the first box cover 430 can be connected with the box body 420 by a buckle, or can be connected by a bolt or other fixing means. The second box cover 440 can be connected with the box body 420 by a buckle or a bolt. The first box cover 430 and the second box cover 440 are convenient to open to overhaul the electric control box 400.

[0084] Referring to Figure 3 When the electric control box 400 is flipped and moved into the cabinet 100, the first box cover 430 faces the air inlet cavity 101, and the second box cover 440 faces the front side of the cabinet 100. In the case that the panel is opened, the second box cover 440 is exposed, and the second box cover 440 is convenient to open. After the second box cover 440 is opened, the outer wiring seat 460 is exposed, and the outer wiring seat 460 is convenient to wire and overhaul.

[0085] Referring to Figure 4 When the electric control box 400 is flipped and moved out of the cabinet 100, the air inlet cavity 101 is opened to expose the compressor 210, the plate heat exchanger and the pipeline assembly 500 and other components. At this time, the first box cover 430 is also exposed, and the first box cover 430 is convenient to open. After the first box cover 430 is opened, the electric control panel 410 and the inner wiring seat 450 are exposed, and the electric control panel 410 and the inner wiring seat 450 are convenient to wire and overhaul.

[0086] It can be understood that part of the terminal 412 is connected with the inner terminal block 450, and in the embodiment, the electric control panel 410 is located above the inner terminal block 450, and the two are arranged adjacent to each other, so that the length of the adapter line is shorter, the wiring is convenient, and the wiring is more reasonable. Part of the terminal 412 can be directly connected with the compressor 210, the fan 300, the sensor and other components in the box body 100, and the wiring operation is also simple, without the need to disassemble the electric control box 400.

[0087] It should be noted that in the embodiment, the box body 420 is connected with the box body 100 through the hinge structure 600, and in the case of opening the first box cover 430 and the second box cover 440, the connection between the box body 420 and the box body 100 can be maintained without disassembling the box body 420, the electric control panel 410, the inner terminal block 450 and the outer terminal block 460, which facilitates wiring and maintenance operation.

[0088] In some embodiments, the inner terminal block 450 and the outer terminal block 460 are arranged in a combined manner of paired matching, that is, the number of the inner terminal block 450 and the outer terminal block 460 is consistent and one-to-one correspondence is set. Since the inner terminal block 450 and the outer terminal block 460 are arranged in opposite directions, the box body 420 can be provided with a through slot connecting the first recess 421 and the second recess 422, and the outer terminal block 460 can pass through the through slot and be connected with the inner terminal block 450. Specifically, it can be fixed by plug-in or clamping and the like, and the assembly is simple. Moreover, after the inner terminal block 450 and the outer terminal block 460 are assembled, the electrical connection between the inner terminal block 450 and the outer terminal block 460 can be realized through the metal conductive structure, without arranging wires between the inner terminal block 450 and the outer terminal block 460.

[0089] It should be noted that the inner terminal block 450 includes an inner strong current terminal block 451 and an inner weak current terminal block 452, and the outer terminal block 460 includes an outer strong current terminal block 461 and an outer weak current terminal block 462. The outer strong current terminal block 461 is connected with the inner strong current terminal block 451 in correspondence, and the outer weak current terminal block 462 is connected with the inner weak current terminal block 452 in correspondence. The outer strong current terminal block 461 is used for connecting the power line and other strong current lines, and the outer weak current terminal block 462 is used for connecting the signal line, the control line and other weak current lines. It should be noted that the outer strong current terminal block 461 and the outer weak current terminal block 462 can be distinguished by using sockets with different numbers of terminals, and the inner strong current terminal block 451 and the inner weak current terminal block 452 can also be distinguished by using sockets with different numbers of terminals, which plays a role in preventing wiring mistakes.

[0090] Referring to Figure 6As shown, the first box cover 430 and the box body 420 are provided with a sealing element 470, and the sealing element 470 can improve the sealing between the first box cover 430 and the box body 420. Specifically, the sealing element 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 containing cavity 401.

[0091] 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. For example, the first sealing ring 471 can be square or other polygonal shapes.

[0092] Referring to Figure 8 and Figure 9 As shown, in some embodiments, the edge of the first box cover 430 towards the box body 420 is provided with a first recess 435, and the first recess 435 is arranged along the circumference of the first box cover 430. The first sealing ring 471 is contained in the first recess 435, and the edge of the box body 420 is provided with a first protrusion 4212. After the first box cover 430 and the box body 420 are assembled in place, the first protrusion 4212 enters the first recess 435 and abuts against the first sealing ring 471. The first protrusion 4212 can compress the first sealing ring 471 to achieve better sealing effect.

[0093] The first recess 435 can be understood as a ring groove arranged around the first box cover 430, and the outer periphery of the box body 420 is provided with a surrounding plate, and the end of the surrounding plate is formed as the first protrusion 4212. In other embodiments, the first recess 435 can be arranged on the periphery of the box body 420, and the first protrusion 4212 can be arranged on the periphery of the first box cover 430. For example, the first recess 435 is formed on the end face of the surrounding plate towards the first box cover 430, and the first protrusion 4212 is correspondingly matched with the first recess 435.

[0094] Referring to Figure 7 As shown, the second box cover 440 and the box body 420 are provided with a sealing element 470, and the sealing element 470 is a second sealing ring 472, which can improve the sealing between the second box cover 440 and the box body 420.

[0095] It can be understood that, as Figure 7As shown, the groove on the side of the box body 420 away from the electric control panel 410 is a 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 being able to block water vapor from entering the second accommodating cavity 402.

[0096] Referring to Figure 8 and Figure 10 As shown, in some embodiments, the end surface of the box body 420 away from the first accommodating cavity 401 is provided with a second recess 4223, which is arranged around the slot of the second groove 422. The second sealing ring 472 is accommodated in the second recess 4223. After the second box cover 440 is assembled with the box body 420, the second box cover 440 abuts against the second sealing ring 472. The second box cover 440 can press the second sealing ring 472 tightly to achieve a better sealing effect.

[0097] In an embodiment, a step surface 4222 can be arranged between the end surface of the box body 420 and the second groove 422. The second recess 4223 can be an annular groove formed in 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 performance is better.

[0098] Referring to Figure 10 As shown, since the external connector 460 needs to be connected with external equipment through the second line 463, a first wire outlet 4221 is arranged on the box body 420 for the second line 463 to pass out. In the embodiment, the first wire outlet 4221 is arranged on the side wall of the second groove 422, and a sealing member 470 is arranged at the first wire outlet 4221. Specifically, a first wire clamping piece 480 is used to seal the first wire outlet 4221, so that the second line 463 can be led out from the first wire outlet 4221, and at the same time, the first wire outlet 4221 can have a high sealing performance to block water vapor from entering the electric control box 400 through the first wire outlet 4221.

[0099] In an embodiment, the first outlet 4221 is a gap formed in the sidewall of the second groove 422, i.e., the first outlet 4221 is open to one side of the second cover 440, facilitating the assembly of the first wire passing card 480 into the first outlet 4221 from the open structure. In order to match the sealing structure of the second groove 422 and the gap, in an embodiment, the second cover 440 includes a first plate body 441 and a second plate body 442 connected to each other, wherein the first plate body 441 covers the second groove 422, and the second plate body 442 covers the gap, so that the second cover 440 can match the arrangement of the second groove 422 and the first outlet 4221.

[0100] It should be noted that, as shown in Figure 7 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, and the first sealing section 4721 matches the first plate body 441 to seal the second groove 422. The second sealing section 4722 matches the shape and size of the gap, and the second sealing section 4722 matches the second plate body 442 to seal the first wire passing card, thereby ensuring better sealing at the first outlet 4221.

[0101] 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 are integrally formed, and the specific shape of the first sealing section 4721 and the second sealing section 4722 can be selected according to the actual shape of the second groove 422 and the first outlet 4221 to match the structure of the second groove 422 and the first outlet 4221.

[0102] As shown in Figure 3 The bottom plate 110 is provided with a third outlet for the second wire 463 to pass out of the cabinet 100, and the third outlet is provided with a sealing body 111 to seal the third outlet. When the second wire 463 is led out of the third outlet, it is sealingly matched with the sealing body 111, which can ensure that the third outlet has high sealing performance, avoid indoor air entering the cabinet 100 through the third outlet, and reduce the occurrence of condensation. In an embodiment, the sealing body 111 can be a sealing sleeve made of rubber, silicone or other materials, which is sleeved on the second wire 463 to maintain close contact and has good sealing effect.

[0103] It should be noted that some of the wiring terminals 412 are equipped with a third line 4121. The control board 410 is electrically connected to the compressor 210, fan 300, sensor and other components in the housing 100 through the third line 4121. Therefore, the housing 420 is provided with a second outlet 4211 for the third line 4121 to pass through. A second wire guide 490 is provided in the second outlet 4211. The second wire guide 490 is used to seal the second outlet 4211, so that the third line 4121 can be led out from the second outlet 4211 while ensuring that the second outlet 4211 has a high degree of sealing and preventing moisture from entering the control box 400 through the second outlet 4211.

[0104] In some embodiments, the first wire guide 480 and the second wire guide 490 employ the same structure to ensure better sealing at the wire exit point of the electrical control box 400. (Refer to...) Figure 10 As shown, the first wire guide 480 is used as an example for explanation. The first wire guide 480 includes a wire guide body 481. The wire guide body 481 is provided with a wire guide groove 482. Multiple sealing pieces 483 are respectively provided at both ends of the wire guide groove 482. The multiple sealing pieces 483 are arranged along the inner peripheral wall of the wire guide groove 482. Adjacent sealing pieces 483 abut against each other. The second line 463 can pass through the adjacent sealing pieces 483 and maintain abutment against the sealing pieces 483 to form an effective sealing structure.

[0105] It is understandable that the entire body 481 of the line card is made of an elastic material, such as rubber or silicone. The sealing sheet 483 has a certain elasticity. When the second line 463 passes through the adjacent sealing sheet 483, the sealing sheet 483 can deform and remain in contact with the second line 463, thus ensuring stable sealing performance.

[0106] Reference Figure 10 As shown, the extension direction of the cable tray 482 is consistent with the extension direction of the first outlet 4221. In this embodiment, two first cable clips 480 can be provided at the first outlet 4221 to seal the high-voltage and low-voltage lines respectively. When the second line 463 passes through the first outlet 4221, the second line 463 enters the cable tray 482. The sealing plates 483 seal both ends of the cable tray 482, effectively preventing moisture from entering the electrical control box 400. The specific structure of the second cable clip 490 can refer to the structure of the first cable clip 480 described above. It should be noted that the specific number of the first cable clips 480 and the second cable clips 490 can be selected according to the number of the first outlet 4221 and the second outlet 4211.

[0107] The electric control element 411 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. 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 sink 700 can take away the heat of the first heating device. The heat sink 700 can be a fin heat sink. The heat sink 700 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, and the heat sink 700 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.

[0108] Referring to Figure 8 and Figure 9 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 heat sink 700, so that the heat sink 700 can pass through the through hole 431, and at least part of the heat sink 700 is exposed outside the first box cover 430. A third sealing ring 473 is arranged between the heat sink 700 and the first box cover 430. Part of the structure of the heat sink 700 is exposed from the through hole 431. The heat sink 700 is provided with a flange 710 along the outer periphery of the side facing the electric control board 410. The third sealing ring 473 is arranged around the heat sink 700 and abuts against the flange 710 on one side. When the first box cover 430 is assembled with the box body 420, the first box cover 430 abuts against the other side of the third sealing ring 473 and presses the third sealing ring 473 tightly, so as to fix the third sealing ring 473 and improve the sealing between the heat sink 700 and the first box cover 430, thereby improving the overall sealing of the electric control box 400.

[0109] It can be understood that when the electric control box 400 is located in the air inlet cavity 101, the first box cover 430 and the heat sink 700 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. Part of the airflow passes through the heat sink 700, thereby helping to improve the heat dissipation efficiency of the heat sink 700.

[0110] In some embodiments, as shown in Figure 8 The heat sink 700 is arranged at the upper end of the electric control box 400. After the electric control box 400 enters the air inlet cavity 101, the heat sink 700 is arranged close to the air inlet 131, which is more conducive to the airflow flowing through the heat sink 700 and improves the heat dissipation effect. It should be noted that the airflow takes away the heat of the heat sink 700 and then exchanges heat with the evaporator, which can recover the heat taken away by the airflow and improve the heating efficiency.

[0111] The utility model embodiment sets up the electric control element 411, the wiring terminal 412 and the radiator 700 on the side of the electric control board 410 towards the first box cover 430, on the one hand can be convenient for the heat dissipation of the radiator 700, the other hand is convenient for the wiring of the wiring terminal 412, guaranteeing that the wiring and the radiator 700 are located on the same side of the electric control board 410, without special production process, it is convenient for production and manufacture.

[0112] 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 that generates heat when in operation and requires waterproof protection measures. Therefore, in some embodiments, the second heating device is arranged in the electric control box 400, and an air duct 432 is arranged on the electric control box 400 to dissipate heat from the second heating device. The second heating device can be an inductor 4111 or other heating device.

[0113] Referring to Figure 6 and Figure 8 , an inductor 4111 is taken as an example for illustration. The inductor 4111 is arranged on the side of the electric control box 400 towards the first box cover 430, and an air duct 432 is formed on the first box cover 430. The first box cover 430 is provided with an air inlet 433 and an air outlet 434, which are respectively communicated with the air duct 432. The air inlet 433 is arranged towards 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 into the air inlet cavity 101, the air outlet 434 is arranged towards the evaporator, and at least part of the structure of the inductor 4111 is located in the air duct 432.

[0114] When the heat pump equipment 10 is in operation, air from the outdoor environment enters the air inlet cavity 101 and flows along the air inlet cavity 101 to the evaporator. Part of the airflow enters the air duct 432 through the air inlet 433 after passing through the radiator 700 and flows along the air duct 432 to the inductor 4111, and then is discharged through the air outlet 434. Referring to Figure 8 , the direction indicated by the arrow is the direction of airflow flowing along the air duct 432. Figure 8

[0115] It should be noted that since the evaporator is close to the air outlet 434 of the air duct 432, the airflow in the air inlet cavity 101 accelerates the airflow speed discharged through the air outlet 434 when passing through the evaporator, thereby generating an air suction effect. Therefore, the airflow circulation of the inductor 4111 can be improved through the air duct 432. Moreover, since the air inlet 433 is arranged towards the radiator 700, the airflow speed passing through the radiator 700 can be accelerated, which is beneficial to improving the heat dissipation efficiency of the radiator 700.

[0116] ​The embodiment of the utility model further provides a hot water heating system, including the heat pump equipment of above -mentioned embodiment. The heat pump equipment 10 can be connected with the external equipment such as gas wall -hanging stove, electric heater or water tank, and constitute hot water heating system, and user provides domestic hot water and heating hot water. The hot water heating system has all beneficial effects of above-mentioned heat pump equipment 10.

[0117] Of course, the utility model is not limited to the above-mentioned implementation, and the skilled person 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.
