Technical Field

[0001] This utility model relates to the technical field of air source heat pump water heater structure, specifically to a wiring structure and its air source heat pump water heater. Background Technology

[0002] In the existing hot water supply equipment field, air source heat pump water heaters have become an important technological solution to replace traditional boilers due to their significant energy-saving and environmentally friendly characteristics. This equipment uses an environmentally friendly refrigerant as the heat transfer medium and extracts low-grade heat energy from ambient air using the reverse Carnot cycle principle. After the compressor performs work, it can stably output domestic hot water at temperatures above 50°C. Its application scenarios cover multiple fields such as commercial venues (hotels, hair salons, bath centers), public facilities (schools, indoor swimming pools), and industrial production, demonstrating good market adaptability.

[0003] The electrical control system inside an air source heat pump water heater requires numerous cables to connect various functional modules. In existing technologies, cable joints are often wrapped with simple insulating tape or protected with ordinary waterproof boxes, resulting in a generally messy and disorganized cable routing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wiring structure and an air source heat pump water heater, so as to solve the problem that the wiring of cables in the existing air source heat pump water heater is generally messy and disorganized.

[0005] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a wiring structure, comprising:

[0006] The waterproof part of the connector has a protective cavity for accommodating the connector of the cable and an inlet and an outlet for the cable to pass through the protective cavity.

[0008] The second aspect of this utility model adopts the following technical solution: an air source heat pump water heater, including the wiring structure described in the first aspect of this utility model.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this air source heat pump water heater, the cable routing structure arranges the cable entry point along the routing channel of one of the cable routing support frames, then enters the waterproof part of the connector from the inlet, and exits from the outlet before being routed in the routing channel of another cable routing support frame, thus ensuring orderly cable routing. Furthermore, all cable joints are placed within the protective cavity of the waterproof part of the connector, providing excellent waterproofing for the cables. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below through specific embodiments:

[0017] like Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model embodiment proposes a cable routing structure, including a waterproof connector 1 and a cable routing support frame 2. The waterproof connector 1 has a protective cavity for accommodating the cable connector and an inlet and an outlet for the cable to pass through the protective cavity. There are two cable routing support frames 2 connected to both sides of the waterproof connector 1. Both cable routing support frames 2 have cable routing channels for the cable to pass through the inlet or the outlet.

[0018] When routing cables using this cable routing structure, the cable entry end is arranged along the cable routing channel of one of the cable routing support frames 2, then enters the waterproof part 1 of the connector from the inlet, and then exits from the outlet and is arranged in the cable routing channel of another cable routing support frame 2, so as to arrange the cables in an orderly manner; and the cable joints are all arranged in the protective cavity inside the waterproof part 1 of the connector to provide a good waterproof effect for the cables.

[0019] To better understand this solution, the following will provide a detailed explanation of the cable support bracket 2 and the waterproof part 1 of the connector.

[0020] First is the waterproof part 1 of the connector plug.

[0021] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, the wiring structure wherein the waterproof part 1 of the connector includes a waterproof cover 11 and a wire conduit 12. The waterproof cover 11 is a box structure with an open bottom. There are two wire conduits 12, one end of which is connected to the outer wall of the waterproof cover 11 and communicates with the inside of the waterproof cover 11. The other end of the two wire conduits 12 is connected to two wiring support frames 2 in a one-to-one correspondence.

[0022] In this embodiment, the top wall of the waterproof cover 11 is fixedly connected to the carrier.

[0023] During the wiring process of the air source heat pump water heater, the cable joints are placed inside the waterproof cover 11 to ensure good waterproof performance at the cable joints. The bottom of the waterproof cover 11 is designed with an opening to allow workers to reach inside the waterproof cover 11 to connect the cable joints, which is convenient and quick.

[0024] Specifically, the two wire conduits 12 are arranged separately on the outside of the waterproof cover 11, which can improve the stability of the cable routing.

[0025] Furthermore, each of the wire conduits 12 includes an inclined conduit section 121, a cover connecting section 122, and a frame connecting section 123. The inclined conduit section 121 is arranged at an inclination. The cover connecting section 122 is arranged horizontally, with one end connected to the waterproof cover 11 and the other end connected to the high end of the inclined conduit section 121. The frame connecting section 123 is arranged horizontally, with one end connected to the corresponding cable support frame 2 and the other end connected to the low end of the inclined conduit section 121.

[0026] In this embodiment, the conduit 12 is composed of an inclined pipe section 121, a cover connecting section 122, and a frame connecting section 123. Even if water enters the frame connecting section 123, because the inclined pipe section 121 is arranged inclined upward from the end connected to the frame connecting section 123, the water cannot enter the cover connecting section 122 from the inclined pipe section 121, and thus cannot enter the waterproof cover 11, thereby further improving the waterproof performance of the waterproof cover 11.

[0027] like Figure 4 As shown, in order to make the cable more stable inside the waterproof cover 11, a cable clamp 13 for binding the cable is provided inside the waterproof cover 11. Specifically, the cable clamp 13 includes a cable clamp 13 body with one end fixedly connected to the inner wall of the waterproof cover 11 and a limiting hole opened on the cable clamp 13 body. After the cable passes through the limiting hole, the cable is bound and limited.

[0028] In this embodiment, there are two wire clamps 13 arranged facing each other inside the waterproof cover 11. The two ends of the cable connector pass through the limiting holes on the wire clamps 13 one by one before being connected, ensuring the connection stability of the cable connector.

[0029] Secondly, there is the cable support frame 2.

[0030] like Figure 1 and Figure 3 As shown, according to another embodiment of the present invention, the wiring structure includes each wiring support frame 2 comprising a connecting part 21 for connecting to a carrier and a plurality of wire support hooks 22 spaced apart along the length direction on one side of the connecting part 21. The space above the plurality of wire support hooks 22 is used to form the wiring channel, and one wire support hook 22 at the end is used at the inlet or outlet of the wiring.

[0031] In this embodiment, the cable tie support hook 22 located at the end is specifically arranged to be connected to the free end of the frame connection section 123 in one of the wire conduits 12. When the cable is arranged, the two ends of the cable are respectively arranged on the corresponding cable support frame 2 and then limited by multiple cable tie support hooks 22. Then, the cable passes through the corresponding wire conduit 12 in sequence and enters the waterproof cover 11 for connection, so as to arrange the cable stably and orderly.

[0032] The connecting part 21 provides a position for the cable support frame 2 to connect with the carrier. In this embodiment, the connecting part 21 has a fixing surface that is attached to the carrier and fixed by multiple screws, and a connecting surface for connecting with multiple cable support hooks 22. The fixing surface and the connecting surface are arranged perpendicularly.

[0033] Furthermore, each of the wire harness support hooks 22 includes a support block 221 and a limiting block 222. The support block 221 is arranged horizontally. There are two limiting blocks 222 connected to the two ends of the top surface of the support block 221. The two limiting blocks 222 form an angle with the support block 221, and one end of the limiting block 222 away from the support block 221 is connected to the connecting part 21.

[0034] In this embodiment, the included angle between the limiting block 222 and the support block 221 connected to the connecting part 21 is 90°. Specifically, the two limiting blocks 222 and the support block 221 are arranged in a "U" shape, and the space formed inside allows the cable to pass through. The support block 221 supports the cable, and the two limiting blocks 222 restrict the cable, stably confining the cable within the space for arrangement.

[0035] Here, one end of the limiting block 222 that is away from the support block 221 is specifically connected to the connecting surface of the connecting part 21.

[0036] To improve the stability of the cable within the cable tie support hook 22, cable ties can also be used to confine the cable within the cable tie support hook 22.

[0037] The above wiring structure is applied to air source heat pump water heaters, such as... Figure 1 As shown, according to another embodiment of the present invention, the air source heat pump water heater includes the wiring structure, water receiving tray 3, and other structures such as the electrical control system described in any of the above embodiments. The wiring structure is connected to the back of the water receiving tray 3. Specifically, the top wall of the waterproof cover 11 and the connecting part 21 are connected to the back of the water receiving tray 3 to arrange the wiring structure reasonably inside the air source heat pump water heater. The cables connected to the electrical control system and other components are arranged on the wiring structure in an orderly manner.

[0038] The wiring structure in this solution has the advantages of simple structure, low cost and strong waterproof capability.

[0039] The wiring structure in this solution is not limited to use in air source heat pump water heaters, but can also be used in other compatible structures.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
