[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figures 1-5 A heat exchange mechanism for an air source heat pump water heater mainly includes: a heat exchange box 1, a dust filter 3, a cleaning device 4, an inspection port 6, and a quick-release device 8. Support columns 2 are fixedly connected to the four corners of the lower end of the heat exchange box 1. A first pipe 11 is fixedly connected to one side of the heat exchange box 1, and a second pipe 12 is fixedly connected to the other side of the heat exchange box 1. Both pipes 11 and 12 are connected to the interior of the heat exchange box 1.

[0031] Then, the dust filter 3 is used to prevent dust and other debris from affecting the heat exchange efficiency of the heat exchange box 1. The cleaning device 4 includes a cleaning brush 5. The cleaning device 4 uses the cleaning brush 5 to scrape off the dust and debris on the dust filter 3 to prevent the filter from clogging.

[0032] Specifically, the cleaning device 4 also includes a chute 13, which is located on both sides of the front end of the heat exchange box 1. A fixing rod 14 is installed in each chute 13, and the upper and lower ends of the fixing rod 14 are fixedly connected to the chute 13. A spring 15 is inserted through the outer periphery of the fixing rod 14. A mounting frame 16 is slidably connected to the fixing rod 14 on both sides. Several evenly distributed cleaning brushes 5 are fixedly connected to the concave surface of the rear end of the mounting frame 16. The upper and lower ends of the spring 15 are fixedly connected to the upper end of the inner wall of the chute 13 and the mounting frame 16, respectively. A dust filter 3 is located at the front end of the heat exchange box 1. The rear end of the cleaning brush 5 is movably connected to the front end of the dust filter 3. A handle 24 is fixedly connected to the front end of the mounting frame 16.

[0033] When cleaning the dust filter 3, grasp the handle 24 and lift it upwards, causing the mounting frame 16 to slide upwards on the fixing rod 14. At the same time, the spring 15 is compressed, and the cleaning brush 5 scrapes off the dust and other debris attached to the dust filter 3. When the mounting frame 16 slides to the top of the fixing rod 14, the handle 24 can be released. Then, under the rebound force of the spring 15 and the action of gravity, the mounting frame 16 slides downwards to reset. While sliding, the dust filter 3 is cleaned again, achieving cleaning without disassembling the dust filter 3, which is more convenient.

[0034] Then, the inspection port 6 is opened at the bottom of the heat exchange box 1, and the inspection cover 7 is provided at the lower end of the inspection port 6. The quick-release device 8 is provided on the front and rear sides of both sides of the inspection cover 7. The quick-release devices 8 are symmetrically arranged on both sides. The quick-release device 8 includes a locking block 9 and a locking groove 10 that cooperate with each other. The quick-release device 8 moves out of the locking groove 10 through the locking block 9 to complete the disassembly of the inspection cover 7.

[0035] Next, the quick-release device 8 also includes a cavity 17, which is opened on the inspection cover 7. A snap-fit ​​block 9 is disposed in the cavity 17. On the side of the snap-fit ​​block 9 away from the cavity 17, there is a protrusion 18 that is fixedly connected to the heat exchange box 1. A snap-fit ​​groove 10 is opened on the protrusion 18. One end of the snap-fit ​​block 9 near the protrusion 18 extends through the cavity 17 into the snap-fit ​​groove 10.

[0036] A damping rod 19 is provided between the snap-fit ​​block 9 and the inner wall of the cavity 17. A second spring 20 is provided on the outer periphery of the damping rod 19. A second groove 21 is provided below the damping rod 19 and is opened on the inspection cover 7. A sliding plate 22 is fixedly connected to the lower end of the snap-fit ​​block 9. Both sides of the sliding plate 22 are slidably connected in the second groove 21. The lower end of the sliding plate 22 passes through the second groove 21 and extends below it. A sealing part 23 is provided between the inspection cover 7 and the inspection port 6 to increase the overall sealing of the device when the inspection cover 7 is installed.

[0037] When the heat exchanger 1 needs maintenance, two operators simultaneously pull the sliding plates 22 at the front and rear ends, causing them to slide away from the protrusion 18 within the sliding groove 21. This moves the locking block 9 away from the locking groove 10 until it is completely disengaged from the locking groove 10 and moves into the cavity 17. At this point, the spring 20 and damping rod 19 are compressed, and the inspection cover 7 is released from its limit, allowing it to be removed and the inspection port 6 to be exposed for maintenance. When installation is required, the locking block 9 is pressed into the locking groove 10 by pulling the sliding plate 22. Then, the inspection cover 7 is reset so that the locking block 9 is aligned with the locking groove 10. The sliding plate 22 can then be released, and the locking block 9 is pushed into the locking groove 10 under the rebound force of the spring 20, thus completing the installation.

[0038] The working principle of the heat exchange box 1 is existing technology, and its operation will not be described in detail here. It should be noted that all electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional, known device such as a computer. Detailed descriptions of known functions and components are omitted in this specific embodiment.
