The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an integrated air source heat pump unit structure, such as Figure 1-4 As shown, the integrated air source heat pump unit structure includes: an air source heat pump body 1, the air source heat pump body 1 being covered with a protective shell for protecting the internal unit structure; a dustproof net 2 installed on the protective shell for isolating dust and impurities; an adjustment frame 3 slidably fitted outside the dustproof net 2, the inner wall of the adjustment frame 3 having a brush pad 4 attached to it by Velcro for contact with the dustproof net 2; a slider 5 fixed on the inner wall of the adjustment frame 3; and an adjustment component installed on the outer wall of the protective shell for adjusting the height of the slider 5.

[0023] In this embodiment, the dustproof net 2 can isolate dust and impurities, preventing dust from entering the air source heat pump body 1 (model DKFXLN series). When dust accumulates on the dustproof net 2 and needs to be cleaned, the height of the slider 5 is adjusted by adjusting the component. Since the adjusting frame 3 is slidably sleeved on the outside of the dustproof net 2 and the inner wall is attached with a brush pad 4 that can contact the dustproof net 2 by Velcro, and the slider 5 is fixed on the inner wall of the adjusting frame 3, adjusting the height of the slider 5 will drive the adjusting frame 3 to move, thereby allowing the brush pad 4 to clean the dustproof net 2, providing a basis for cleaning the surface of the air source heat pump unit.

[0024] In a further preferred embodiment of the present invention, the adjustment assembly includes: a fixing plate 6 fixed on the outer wall of the protective shell; a threaded rod 7 rotatably mounted on the fixing plate 6, the slider 5 being threadedly sleeved on the threaded rod 7; and a servo motor 8 mounted on the outer wall of the protective shell for driving the threaded rod 7 to rotate, the output shaft of the servo motor 8 being connected to the threaded rod 7.

[0025] In this embodiment, when the dustproof net 2 needs to be cleaned, the servo motor 8 (NEMA 23) is started. The output shaft of the servo motor 8 drives the threaded rod 7 to rotate on the fixed plate 6. Since the slider 5 is threaded onto the outside of the threaded rod 7, according to the principle of threaded transmission, the rotation of the threaded rod 7 will cause the slider 5 to move along the axial direction of the threaded rod 7. The slider 5 is fixed on the inner wall of the adjusting frame 3. When the slider 5 moves, it will drive the adjusting frame 3 to slide outside the dustproof net 2. The brush pad 4 on the inner wall of the adjusting frame 3 comes into contact with the dustproof net 2. During the movement of the adjusting frame 3, the brush pad 4 cleans the dustproof net 2. The threaded transmission has high precision and can accurately control the moving distance of the slider 5, thereby ensuring the accurate movement position of the adjusting frame 3 and enabling the brush pad 4 to effectively clean the dustproof net 2 thoroughly.

[0026] In a further preferred embodiment of the present invention, a fan 9 and a filter box 10 are installed on the adjustment frame 3. The air inlet end of the fan 9 is connected to the filter box 10. A dust suction pipe 11 is installed on the side of the filter box 10 away from the fan 9. The dust suction pipe 11 is fixed on the adjustment frame 3 and has an air inlet branch pipe.

[0027] In this embodiment, when the dust cleaning operation on the dustproof net 2 is initiated (by adjusting the adjusting frame 3 to move the brush pad 4 to clean the dustproof net 2), the fan 9 (XTF series) starts working. The air inlet of the fan 9 is connected to the filter box 10. Under the suction of the fan 9, a negative pressure environment is generated. Since the suction pipe 11 is fixed on the adjusting frame 3 and has an air inlet branch pipe, which can be distributed at different positions around the dustproof net 2, under the negative pressure, the dust on the dustproof net 2 brushed up by the brush pad 4 and... Dust in the surrounding air enters the suction pipe 11 through the air intake manifold, and then enters the filter box 10. The dust entering the filter box 10 is intercepted by the filter device inside the filter box 10, while the filtered air is discharged through the air outlet of the fan 9, preventing the dust from being released back into the air. The dust collection system composed of the fan 9, the filter box 10 and the suction pipe 11 further enhances the dust cleaning effect. It can not only clean the dust on the surface of the dustproof net 2, but also adsorb the dust in the surrounding air, making the cleaning more thorough and preventing secondary pollution.

[0028] In a further preferred embodiment of the present invention, a baffle 13 is detachably installed on the filter box 10, a support ring 14 is fixed on the baffle 13, a filter bag 16 for filtering and isolating dust is installed on the support ring 14, and the outer wall of the support ring 14 is in contact with the inner wall of the filter box 10.

[0029] In this embodiment, when the fan 9 operates and generates negative pressure, dust enters the filter box 10 through the suction pipe 11 with the air. The dust-laden air first comes into contact with the filter bag 16 installed on the support ring 14. The filter bag 16 uses its own filtration structure to isolate the dust in the air outside the filter bag 16, while the relatively clean air passes through the filter bag 16 and is discharged by the fan 9 through the subsequent channel. As the usage time increases, a large amount of dust will accumulate on the filter bag 16, resulting in a decrease in filtration effect. At this time, the detachable baffle 13 can be removed. Since the baffle 13 and the filter box 10 can be detached and installed, and the support ring 14 is fixed on the baffle 13 and the filter bag 16 is installed on the support ring 14, after removing the baffle 13, the support ring 14 and the filter bag 16 can be easily removed from the filter box 10, and then a new filter bag 16 can be replaced and the baffle 13 can be reinstalled.

[0030] In a further preferred embodiment of the present invention, the filter box 10 is provided with a clamping plate 12 for stabilizing the baffle 13, and the baffle 13 is threadedly installed with a limiting bolt that is threadedly connected to the filter box 10 for stabilizing the baffle 13. The support ring 14 is provided with a sealing ring 15 that contacts the inner wall of the filter box 10 for preventing dust leakage.

[0031] In this embodiment, after the support ring 14 with filter bag 16 is installed into the filter box 10, the baffle 13 is placed in a suitable position. At this time, the clamping plate 12 will play a preliminary positioning and stabilizing role for the baffle 13, preventing the baffle 13 from shaking randomly. Then, the limiting bolt is screwed into the baffle 13 and threadedly connected to the filter box 10 using a tool, further fixing the baffle 13 firmly on the filter box 10. When the fan 9 is working and air enters the filter box 10 through the dust suction pipe 11, the sealing ring 15 can prevent dust from leaking out from the gap between the filter bag 16 and the inner wall of the filter box 10, ensuring that dust can only be intercepted and filtered by the filter bag 16.

[0032] In a further preferred embodiment of the present invention, the bottom of the air source heat pump body 1 is provided with a base 17, the bottom of the base 17 is provided with a shock-absorbing pad 18 for shock absorption, and the bottom of the base 17 is provided with a mounting seat 19 for supporting the air source heat pump body 1 by means of fixing bolts 20.

[0033] In this embodiment, the combination of the base 17 and the mounting base 19 provides a stable support structure for the air source heat pump body 1, ensuring that the air source heat pump body 1 will not shake or tilt during operation, thus guaranteeing the normal operation and safety of the unit. The damping pad 18 can effectively reduce the vibration of the air source heat pump body 1 during operation, reduce the damage of vibration to the internal parts of the unit, extend the service life of the unit, and at the same time, reduce the noise pollution of the surrounding environment caused by vibration, improving the comfort of the user environment. The mounting base 19 is installed at the bottom of the base 17 by fixing bolts 20. This installation method is simple and convenient, and it is easy to install and disassemble when needed, improving the installation efficiency and flexibility of the equipment.

[0034] In a further preferred embodiment of the present invention, the protective shell is provided with an operating port, and a protective door for closing the operating port is hinged to one side of the protective shell, and the protective door is provided with a latch for locking the protective door.

[0035] In this embodiment, when it is necessary to inspect, maintain, or clean the dust filter 2 of the air source heat pump body 1, the operator uses a key or appropriate tool to open the latch on the protective door, release the locked state of the protective door, and then pushes the protective door. Since the protective door is hinged to one side of the protective shell, the protective door will rotate around the hinge axis, thereby opening the operating port. The operator can then perform various operations on the air source heat pump body 1 through the opened operating port, such as checking the equipment operating status, replacing parts, and cleaning the dust on the dust filter 2.

[0036] In a further preferred embodiment of the present invention, the top of the air source heat pump body 1 is provided with a dust cover, a support rod for supporting the dust cover is provided between the top of the dust cover and the protective shell, and an opening for air circulation is provided between the dust cover and the protective shell.

[0037] In this embodiment, in addition to the protective shell itself providing dust protection for the air source heat pump body 1, the addition of the dust cover forms a double dust barrier. The opening design between the dust cover and the protective shell ensures air circulation while effectively blocking most of the dust from entering, greatly improving the dust protection performance of the air source heat pump body 1 and extending the service life of the equipment. The setting of the support rod forms a stable support structure between the dust cover and the top of the protective shell, ensuring that the dust cover will not shake or shift during the operation of the air source heat pump body 1, thus ensuring the stability and reliability of the dust cover.

[0038] In summary, compared with related technologies, this device effectively isolates dust and impurities by setting up a dustproof net 2, preventing dust from entering the air source heat pump unit. At the same time, the adjusting component drives the adjusting frame 3 to move, allowing the brush pad 4 to clean the dustproof net 2, ensuring the cleanliness of the dustproof net 2 and ensuring the normal operation of the unit. While the adjusting frame 3 moves to clean the dustproof net 2, the dust collection system composed of the fan 9, filter box 10 and suction pipe 11 works, not only cleaning the dust on the surface of the dustproof net 2, but also adsorbing dust in the surrounding air, making the cleaning more thorough and preventing secondary pollution.

[0039] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
