[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] A modular air conditioning unit includes a support frame 1 and a protruding frame 3 fixedly connected to the top left side. An indoor unit 7 is fixedly installed on the top of the support frame 1, and an outdoor unit 8 is installed in the middle of the protruding frame 3. The indoor unit 7 and the outdoor unit 8 are connected by a connecting pipe. An isolation frame 4 is fixedly connected to the right side of the protruding frame 3. An insulation board 5 is installed inside the isolation frame 4. A through groove 34 is provided on the front side of the outdoor unit 8, and a cleaning mechanism is installed in the through groove 34.

[0019] This section is based on Figures 1-5 and 13- Figure 15The described embodiment is as follows: To facilitate the installation of a modular air conditioning unit in a small factory, and to allow for regular cleaning of the fan blades inside the outdoor unit, thereby extending their service life and further reducing power consumption, the protruding bracket 3 is aligned with the pre-reserved opening for a small window located above the wall of the small factory and extends outward to the outside of the wall. The pre-reserved opening for the small window can be filled by the width of the protruding bracket 3 and the support bracket 1, depending on the actual situation. Then, the outdoor unit 8 is fixedly installed in the middle of the protruding bracket 3, and the indoor unit 7 is fixedly installed on the top of the support bracket 1. The two are fixed and connected by a connecting pipe. To prevent air leakage inside the factory area, an insulation frame 4 is installed between the support bracket 1 and the protruding bracket 3. The insulation frame 4 is filled with an insulation board 5, which is commercially available. The technical details are omitted. Further, during installation, the connecting pipe passes through the interior of the insulation frame 4, thus facilitating the insulation of external temperatures through the cooperation between the insulation frame 4 and the insulation board 5. Furthermore, the modular installation method described above allows for easy disassembly and temporary use of the air conditioning unit. The height of the support frame 1 can be adjusted according to actual use, ensuring its bottom touches the ground. The support frame 1 is then installed on the ground by the operator. To facilitate long-term cleaning of the fan surface inside the outdoor unit, a through groove 34 is machined on the front side of the outdoor unit 8. A cleaning mechanism is installed within the through groove 34, allowing for periodic cleaning of the fan blades inside the outdoor unit, improving their lifespan and reducing power consumption caused by excessive dust accumulation on the blade surface.

[0020] The top of the support frame 1 is fixedly connected to a baffle 2 by a bolt assembly 35, and the upper surface of the baffle 2 is in contact with the bottom of the indoor unit 7.

[0021] This section is based on Figures 1-5 and 13- Figure 15 The described embodiment is as follows: The operator uses bolt assembly 35 to fix the baffle 2 to the top of the support frame 1, ensuring close contact between the upper surface of the baffle 2 and the bottom of the indoor unit 7. Utilizing the detachable fixing characteristic of bolt assembly 35, a stable connection between the baffle 2 and the support frame 1 is achieved. Simultaneously, the baffle 2 provides bottom support and limitation for the indoor unit 7. The cooperation between the baffle 2 and bolt assembly 35 provides stable support for the indoor unit 7, preventing direct contact between the indoor unit 7 and the support frame 1, thus avoiding bottom wear. It also enhances the stability of the indoor unit 7 after installation, preventing displacement due to vibration during use. The detachable design of bolt assembly 35 facilitates the removal and replacement of the baffle 2, and also facilitates subsequent inspection and maintenance of the indoor unit 7, further improving the installation convenience and service life of the air conditioning unit. Bolt assembly 35 is a combination of bolts and nuts, which is existing technology and will not be described in detail.

[0022] A transition pipe is provided on the rear side of the isolation frame 4, and the connecting pipe passes through the transition pipe to connect the indoor unit 7 and the outdoor unit 8.

[0023] This section is based on Figures 1-5 and 13- Figure 15 The described embodiment is as follows: A transition pipe is set on the rear side of the isolation frame 4, through which the connecting pipe between the indoor unit 7 and the outdoor unit 8 passes. This allows the connecting pipe to achieve a through-fit with the isolation frame 4, ensuring a stable connection between the indoor unit 7 and the outdoor unit 8 while forming a tight fit with the isolation frame 4. The transition pipe provides a dedicated through-channel for the connecting pipe, preventing the connecting pipe from directly passing through the isolation frame 4 and causing damage to the isolation frame 4, thus ensuring the structural integrity of the isolation frame 4. At the same time, the transition pipe can limit and protect the connecting pipe, preventing it from loosening or breaking due to vibration, pulling, etc., ensuring stable medium transmission between the indoor unit 7 and the outdoor unit 8, further improving the operational stability of the air conditioning unit. In addition, in conjunction with the insulation board 5 inside the isolation frame 4, it reduces temperature loss during pipe transmission.

[0024] The bottom rear side of the insulation board 5 is provided with a groove 6, and the transition tube is located in the groove 6.

[0025] This section is based on Figures 1-5 and 13- Figure 15 The described embodiment is as follows: a groove 6 is provided at the bottom rear side of the insulation board 5, and the transition tube is placed in the groove 6 so that the transition tube and the insulation board 5 fit together. The limiting effect of the groove 6 is used to ensure that the position of the transition tube, the insulation board 5, and the isolation frame 4 is relatively fixed.

[0026] The outdoor unit 8 is fixedly connected to the front of the interior with a base 26. The top of the base 26 is rotatably connected to an active rod 27. The left side of the active rod 27 is fixedly connected to an annular seat 28. Multiple fan blades 29 are evenly fixedly connected to the outer surface of the annular seat 28 along the circumferential direction.

[0027] This section is based on Figures 1-10 and 13- Figure 15 The described embodiment is as follows: the base 26 is fixedly connected to the front of the interior of the outdoor unit 8, and the drive rod 27 is rotatably connected to the top of the base 26. The drive rod 27 can be powered by the assembly of a motor, belt and pulley by the operator. When the drive rod 27 rotates, the annular seat 28, which is fixedly installed on the left side of the drive rod 27 by bolts, rotates synchronously. Then, the multiple fan blades 29 fixedly connected to the annular seat 28 along the circumferential direction perform circular motion to generate wind speed, which cools the pipes of the condenser inside the outdoor unit 8.

[0028] The cleaning mechanism includes a connecting cover 10 and a cover plate 11 detachably fixed to the top of the connecting cover 10. The connecting cover 10 has an elongated hole 12 on its front and rear sides respectively. A crossbar 14 is slidably connected in each of the two elongated holes 12. The two crossbars 14 are fixedly connected to the top sides of the lifting seat 13 respectively. An annular long frame 20 is fixedly connected to the middle of the lifting seat 13. A short rod 16 is rotatably connected to the middle of the annular long frame 20. A circular plate 24 is fixedly connected to one side of the short rod 16. Multiple fan-shaped brushes 25 are evenly fixedly connected to one side of the circular plate 24 along the circumferential direction. A transmission rod 17 is rotatably connected to the upper side of the annular long frame 20. A sprocket 18 is fixedly connected to the short rod 16 and the transmission rod 17 respectively. The two sprockets 18 are connected by a transmission chain 19. The bottom of the connecting cover 10 is fixed and connected to the through groove 34.

[0029] This section is based on Figures 1-10 and 13- Figure 15The described embodiment is as follows: The cleaning mechanism consists of a connecting cover 10, a cover plate 11, a crossbar 14, a lifting seat 13, an annular long strip frame 20, a short rod 16, a circular plate 24, a fan-shaped brush 25, a transmission rod 17, a sprocket 18, and a transmission chain 19. The bottom of the connecting cover 10 is fixed and connected to the through slot 34 of the outdoor unit 8. The cover plate 11 is detachably fixed to the top of the connecting cover 10. Two long strip holes 12 are respectively opened on the front and rear sides of the connecting cover 10. Two crossbars 14 are slidably connected to the two long strip holes 12 and fixed to the top sides of the lifting seat 13, so that the lifting seat 13 can slide up and down along the long strip holes 12 through the crossbars 14. The annular long strip frame 20 is fixed in the middle of the lifting seat 13, and the short rod 16 is rotatably connected to the annular long strip frame 20. In the middle of the frame 20, a circular plate 24 is fixed to one side of a short rod 16, and multiple fan-shaped brushes 25 are evenly fixed to one side surface of the circular plate 24 along the circumferential direction. A transmission rod 17 is rotatably connected to the upper side of the annular frame 20. Two sprockets 18 are fixed to the short rod 16 and the transmission rod 17 respectively. The transmission chain 19 realizes the transmission connection between the two sprockets 18. A motor output shaft is fixedly connected to one side of the transmission rod 17 through a coupling. The motor is fixedly connected to the top of the annular frame 20. The drive motor makes the transmission rod 17 rotate, so that the circular plate 24 on the short rod 16 rotates when the transmission chain 19 realizes the transmission connection between the two sprockets 18. Then, the multiple fan-shaped brushes 25 located on the circular plate 24 perform circumferential motion. During cleaning, the drive transmission rod 17 rotates, causing the sprocket 18 on it to rotate. This rotation, via the transmission chain 19, drives the sprocket 18 on the short rod 16 to rotate synchronously. This, in turn, causes the short rod 16, the circular plate 24, and the fan-shaped brush 25 to rotate. Simultaneously, this pushes the lifting seat 13 up and down along the elongated hole 12, causing the fan-shaped brush 25 to move downwards along the trajectory of the elongated hole 12, extending into the outdoor unit 8 and fully contacting the surface of the fan blades 29. The fan-shaped brush 25, made of plastic, cleans the surface of the fan blades 29. This cleaning mechanism allows for the periodic cleaning of the fan blades 29 inside the outdoor unit 8. The rotation of the fan-shaped brush 25 and the up-and-down movement of the lifting seat 13 contribute to this process. The system can thoroughly clean the dust on the surface of the fan blades 29, preventing dust accumulation from affecting the rotation efficiency and heat dissipation of the fan blades 29, further reducing power consumption, and extending the service life of the fan blades 29 and the outdoor unit 8. The detachable design of the cover plate 11 facilitates the inspection and replacement of the fan-shaped brush 25, transmission components, etc. inside the cleaning mechanism. The tight fit between the connecting cover 10 and the through groove 34 can prevent dust from drifting into other components inside the outdoor unit 8 during the cleaning process, while also preventing external debris from entering the outdoor unit 8, ensuring a clean internal environment for the outdoor unit 8. The transmission cooperation between the transmission chain 19 and the sprocket 18 ensures stable power transmission, making the rotation of the fan-shaped brush 25 smoother and improving the cleaning effect.

[0030] A concave frame 15 is fixedly connected to the front and rear sides of the top of the lifting seat 13. The two concave frames 15 are mirror images of each other and are in sliding contact with the front and rear sides of the connecting cover 10 through their concave shapes.

[0031] This section is based on Figures 1-10 and 13- Figure 15 The described embodiment is as follows: two concave frames 15 are fixedly connected to the front and rear sides of the top of the lifting seat 13, and the two concave frames 15 are arranged in a mirror image. Utilizing the concave structure of the concave frames 15, they are respectively snapped into sliding contact with the front and rear sides of the connecting cover 10. When the lifting seat 13 slides up and down along the elongated hole 12 via the crossbar 14, the concave frames 15 slide synchronously along the front and rear sides of the connecting cover 10, which plays a guiding role in the sliding direction of the lifting seat 13.

[0032] A vertical slide bar 9 is fixedly connected to the top of the outdoor unit 8, and a right-angle bracket 21 is fixedly connected to the horizontal bar 14 on the rear side. A positioning hole 22 is provided on the top of the right-angle bracket 21, and the vertical slide bar 9 is slidably connected in the positioning hole 22. The movable end of the electric push rod 23 is fixedly connected to the rear side of the right-angle bracket 21, and the fixed end of the electric push rod 23 is fixedly connected to the top of the outdoor unit 8.

[0033] This section is based on Figures 1-10 and 13- Figure 15 The described embodiment is as follows: a vertical slide bar 9 is fixedly connected to the top of the outdoor unit 8, and a right-angle bracket 21 is fixedly connected to the horizontal bar 14 located at the rear. A positioning hole 22 is opened at the top of the right-angle bracket 21, allowing the vertical slide bar 9 to slide within the positioning hole 22. The movable end of the electric push rod 23 is fixedly connected to the rear side of the right-angle bracket 21, and the fixed end of the electric push rod 23 is fixedly connected to the top of the outdoor unit 8. During operation, the movable end of the electric push rod 23 is driven to extend and retract, causing the right-angle bracket 21 to slide up and down along the vertical slide bar 9, thereby causing the horizontal bar 14, the lifting seat 13, and the entire cleaning mechanism to move up and down synchronously, achieving the lifting and cleaning of the fan blades 29.

[0034] The top rear side of the protruding frame 3 is fixedly connected to two base plates 32 by two screws 33. The front sides of the two base plates 32 are respectively fixedly connected to the bottom sides of the right angle plate 31. The front side of the right angle plate 31 is fixedly connected to a side cover 30, which covers the electric push rod 23 inside.

[0035] This section is based on Figures 1-10 and 13- Figure 15The described embodiment is as follows: two base plates 32 are fixedly connected to the top rear side of the protruding frame 3 by two screws 33, and the front sides of the two base plates 32 are fixedly connected to the bottom sides of the right angle plate 31 respectively, so that the right angle plate 31 is fixed to the protruding frame 3 by the base plates 32 and screws 33. Then, the side cover 30 is fixedly connected to the front side of the right angle plate 31, so that the side cover 30 completely covers the electric push rod 23 inside, forming a protective enclosure for the electric push rod 23.

[0036] The right-angle plate 31 and the side cover 30 are detachably connected.

[0037] The specific operating principle of this invention is as follows: During installation, the protruding bracket 3 is aligned with the reserved opening of the small window above the wall of the small factory and extends to the outside of the wall, filling the gap of the reserved opening; the indoor unit 7 is supported by the support frame 1, and the operator uses bolt assembly 35 to fix the baffle 2 to the top of the support frame 1, so that the baffle 2 fits against the bottom of the indoor unit 7, achieving stable support and avoiding wear. The outdoor unit 8 is fixed in the middle of the protruding bracket 3, and the two are connected by a connecting pipe. The connecting pipe passes through the transition pipe on the back side of the isolation frame 4. The isolation frame 4 is filled with insulation board 5, and the groove 6 at the bottom of the back side of the insulation board 5 limits the transition pipe, achieving temperature isolation and pipe protection, preventing air leakage in the factory area and pipe temperature loss.

[0038] Inside the outdoor unit 8, the base 26 is fixed to the front side, and the drive rod 27 is rotatably connected to the top of the base 26. The annular seat 28 on its left side drives multiple fan blades 29 to rotate, cooling the condenser inside the outdoor unit. To facilitate cleaning the dust accumulated on the fan blades 29, a cleaning mechanism is installed in the through groove 34 on the front side of the outdoor unit 8. The bottom of the connecting cover 10 is connected to the through groove 34, and the cover plate 11 is removable for easy maintenance.

[0039] During cleaning, the drive rod 17 rotates the short rod 16 via the sprocket 18 and drive chain 19, causing the fan-shaped brush 25 on the circular plate 24 to rotate. Simultaneously, the electric push rod 23 extends and retracts, causing the right-angle frame 21 to slide along the vertical slide bar 9. This, in turn, causes the lifting seat 13 to move up and down along the elongated hole 12 of the connecting cover 10 via the crossbar 14. The concave frame 15 guides the sliding of the lifting seat 13, ensuring that the fan-shaped brush 25 fully contacts the fan blades 29 for cleaning. Furthermore, the side cover 30 is fixed to the protruding frame 3 via the right-angle plate 31, the base plate 32, and screws 33, protecting the electric push rod 23 and preventing damage.

[0040] The overall modular design facilitates disassembly and temporary use. The components work together to achieve functions such as cooling, heat preservation, and fan blade cleaning, effectively improving the stability and service life of the unit and reducing power consumption.
