[0017] Furthermore, the improvement of the present invention is that the lifting component adopts a cylinder, and the motor adopts a servo motor.

[0018] Furthermore, the improvement of the present invention is that a plurality of ventilation holes are provided at the bottom end of the protective frame.

[0019] The liquid infiltrated into the protective frame can be discharged at the ventilation holes.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides an air source heat pump with a waterproof structure, having the following beneficial effects:

[0022] Enhanced waterproof performance: By setting baffles with adjustable tilt angles, it can effectively block rain and snow from entering the ventilation end of the air source heat pump outdoor unit during the rainy or snowy seasons, reducing the risk of internal components being corroded and aged due to water ingress, and extending the service life of the air source heat pump.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-5, an air source heat pump with a waterproof structure according to the present invention includes an air source heat pump outdoor unit main body 1. An annular seat 2 is provided at the ventilation end of the air source heat pump outdoor unit main body 1, and a dust-proof plate 3 is arranged inside the annular seat 2;

[0033] A protective frame 12 is provided at the front end of the air source heat pump outdoor unit main body 1. The annular seat 2 is located inside the protective frame 12. An opening is provided at the front end of the protective frame 12. A plurality of positioning shafts 13 are sequentially arranged from top to bottom in the opening. A baffle 14 is fixedly arranged on the positioning shaft 13. Both ends of the positioning shaft 13 are rotatably connected to the protective frame 12, and two tooth blocks 15 are symmetrically arranged at both ends of the positioning shaft 13. Two toothed plates 16 are symmetrically arranged on both sides of the protective frame 12. The toothed plates 16 are engaged with a plurality of tooth blocks 15, and the tops of the two toothed plates 16 are connected by a cross plate. A lifting assembly 17 is provided at the upper end of the protective frame 12, and a lifting rod 18 connecting the cross plate is arranged at the output end of the lifting assembly 17;

[0034] An annular sleeve 5 is rotatably arranged on the outer peripheral side of the annular seat 2. A cleaning rod 6 is arranged on the annular sleeve 5. A brush contacting the dust-proof plate 3 is arranged on the cleaning rod 6. A rotating shaft 7 is arranged in the middle part of the cleaning rod 6. A driven gear 8 is arranged at the outer end of the rotating shaft 7. A motor 9 is arranged inside the protective frame 12. A driving gear 10 is arranged at the output end of the motor 9. The driving gear 10 and the driven gear 8 are connected by a chain 11.

[0035] In this embodiment, the lifting assembly 17 adopts a cylinder, and the motor 9 adopts a servo motor.

[0036] In this embodiment, a plurality of ventilation holes are provided at the bottom end of the protective frame 12.

[0037] Waterproof and protection mechanism: When encountering bad weather such as rainy season or snowy season, start the lifting assembly 17 (such as a cylinder). The output end of the cylinder pushes the lifting rod 18 to drive the cross plate connected thereto. Since the cross plate is connected to the toothed plates 16 on both sides, the two toothed plates 16 will rise or fall synchronously. The toothed plates 16 are engaged with the tooth blocks 15 at both ends of the positioning shaft 13. The lifting and lowering of the toothed plates 16 will cause a plurality of tooth blocks 15 to rotate synchronously, thereby driving the positioning shaft 13 to rotate, and finally adjusting the inclination degree of the baffle 14 on the positioning shaft 13. The inclined baffle 14 can change the flow direction of rainwater or snow, making it not easy to enter the protective frame 12, thus effectively reducing the possibility of rainwater or snow entering the annular seat 2 at the ventilation end of the air source heat pump outdoor unit main body 1, playing a role of waterproof protection.

[0038] Dust-proof plate 3 cleaning mechanism: During daily use, in order to ensure the normal operation of the air source heat pump, it is necessary to clean the dust-proof plate 3. Start the motor 9 (a servo motor), and the drive gear 10 at the output end of the motor 9 starts to rotate. The drive gear 10 is docked with the driven gear 8 at the outer end of the rotating shaft 7 of the cleaning rod 6 through the chain 11, thereby driving the rotating shaft 7 to rotate, and making the cleaning rod 6 rotate around the outer peripheral side of the annular seat 2. The brush on the cleaning rod 6 contacts the dust-proof plate 3. During the rotation of the cleaning rod 6, the brush can clean the dust and impurities accumulated on the dust-proof plate 3, maintain the air permeability of the dust-proof plate 3, and ensure that the heat exchange efficiency of the air source heat pump is not affected.

[0039] In this embodiment, an auxiliary fan 19 is provided on one side of the air source heat pump outdoor unit main body 1, a first air guide box 20 is provided on one side of the protective frame 12, the output end of the auxiliary fan 19 is docked with the first air guide box 20 through a first conduit, a plurality of first through holes communicating with the first air guide box 20 are provided inside the protective frame 12, a dust suction device 21 is provided on the other side of the air source heat pump outdoor unit main body 1, a second air guide box is provided on the other side of the protective frame 12, the output end of the dust suction device 21 is docked with the second air guide box through a second conduit, and a plurality of second through holes communicating with the second air guide box are provided inside the protective frame 12.

[0040] Auxiliary ventilation and dust suction mechanism: During the rainy season, since the inclination of the baffle 14 may affect the normal ventilation efficiency of the air source heat pump, the auxiliary fan 19 is started at this time. The auxiliary fan 19 transports air to the first air guide box 20 through the first conduit. The first air guide box 20 communicates with a plurality of first through holes inside the protective frame 12, enabling air to enter the protective frame 12, providing an auxiliary ventilation function for the protective frame 12, and ensuring that the air source heat pump can still operate normally in bad weather. When cleaning the dust-proof plate 3, the dust suction device 21 is started. The dust suction device 21 extracts the air in the second air guide box through the second conduit. The second air guide box communicates with a plurality of second through holes inside the protective frame 12, and the dust and impurities cleaned off will be sucked into the second air guide box along with the air and finally collected by the dust suction device 21, preventing dust from accumulating inside the protective frame 12.

[0041] In this embodiment, an annular frame 4 located inside the annular seat 2 is provided on the periphery of the dust-proof plate 3, and the annular frame 4 is threadedly connected to the annular seat 2. Both ends of the cleaning rod 6 are fixed to the annular sleeve 5 by screws.

[0042] In this embodiment, a bottom block 22 is provided at the bottom of the toothed plate 16, a vertical rod passing through the bottom block 22 is provided at the bottom of the protective frame 12, and the bottom block 22 is slidably connected to the vertical rod.

[0043] Component Installation and Drainage Mechanism: The dust-proof plate 3 is installed in the annular seat 2 through the annular frame 4 on its peripheral side. The annular frame 4 is threadedly connected to the annular seat 2. This connection method facilitates the installation and disassembly of the dust-proof plate 3, and is convenient for replacing or maintaining the dust-proof plate 3. Both ends of the cleaning rod 6 are fixed to the annular sleeve 5 by screws, which is convenient for the installation and repair of the cleaning rod 6. The bottom block 22 at the bottom of the toothed plate 16 is slidably connected to the vertical rod at the bottom of the protective frame 12, which improves the stability of the toothed plate 16 during the lifting process and ensures that the baffle 14 can be accurately adjusted to the required inclination angle. Multiple ventilation holes are provided at the bottom end of the protective frame 12. When liquid accidentally seeps into the protective frame 12, the liquid can be discharged through these ventilation holes, preventing the liquid from accumulating in the protective frame 12 and further protecting the internal components of the air source heat pump.

[0044] Stable and Reliable Operation: The sliding connection design between the toothed plate 16 and the vertical rod improves the stability of the lifting of the toothed plate 16, ensures that the baffle 14 can be accurately adjusted in inclination angle, and guarantees the reliable operation of the waterproof function. At the same time, the ventilation hole design at the bottom end of the protective frame 12 can timely discharge the infiltrated liquid, further improving the stability of the equipment operation.

[0045] Precise Control: Using a cylinder as the lifting component 17 can provide a stable driving force, accurately control the lifting height of the baffle 14, and thus precisely adjust the inclination angle of the baffle 14. The use of a servo motor can precisely control the rotation speed and direction of the motor 9, realizing precise control of the rotation of the cleaning rod 6 and improving the cleaning effect.
