Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a combined air conditioner with a self-cleaning function. Background Technology

[0002] Modular air conditioning systems are widely used in large buildings, office areas, and shopping malls, and are favored for their integration of temperature regulation, humidity control, and air purification. Traditional modular air conditioning systems typically consist of multiple components such as air conditioning units, cooling towers, and ductwork systems, achieving indoor environmental comfort through heat exchange and air circulation. However, with increasing health awareness, problems with air quality and hygiene in traditional modular air conditioning systems have become increasingly apparent, especially during flu seasons or in areas with poor air quality, where large amounts of pathogenic bacteria and particulate matter in the air become significant factors affecting indoor air quality.

[0003] The utility model patent with publication number CN212538102U discloses a modular air conditioner with a self-cleaning function. The unit has an air inlet section and an air outlet section at both ends. The air inlet section has an air inlet, and the air outlet section has an air outlet. Between the air inlet and outlet sections are a return air section and a sterilization section, with the sterilization section equipped with a sterilization device. It also includes a bacterial detection device, a return air duct, and a control device. This air conditioner achieves secondary sterilization by adding components such as a bacterial detection device. However, due to the lack of a self-cleaning mechanism, dust, mold, and other harmful substances accumulate inside during long-term use. After multiple air circulation cycles, it may not be able to efficiently guarantee the cleanliness of the exhaust air. Therefore, it is necessary to design a modular air conditioner with a self-cleaning function to address the shortcomings of the existing technology. Utility Model Content

[0005] The technical implementation scheme of this utility model is as follows: A modular air conditioner with self-cleaning function includes a modular air conditioner body, which serves as the carrier of this device. A centrifugal fan is fixedly installed on one side of the inner wall of the modular air conditioner body. The air outlet of the centrifugal fan is connected to the side wall of the modular air conditioner body. The centrifugal fan is the power source for guiding the airflow of this modular air conditioner body. It also includes an air humidification component disposed within the modular air conditioner body near the centrifugal fan, and a filter component disposed within the modular air conditioner body on the side away from the centrifugal fan. The air humidification component and the filter component are connected... The modular air conditioning unit also includes a coil. One end of the modular air conditioning unit has an air outlet channel, where the air outlet of the centrifugal fan is connected to the air outlet channel. The other end of the modular air conditioning unit has an air inlet channel. Symmetrical grooves are provided on both sides of the air inlet and air outlet channels. Mounting plates are slidably connected to the air inlet and air outlet channels via elastic elements. The mounting plates are located in the corresponding grooves. Filter plates are fixedly mounted between the mounting plates. The filter plates are used to initially filter the air in the modular air conditioning unit. Vibrating elements for vibrating the filter plates are provided outside the air inlet and air outlet channels.

[0006] As an improvement to the above solution, the elastic element includes a guide rod and a spring.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0023] A type of combined air conditioner with self-cleaning function, such as Figures 1-6 As shown, the system includes a modular air conditioning unit 1, which serves as the carrier of this equipment. A centrifugal fan 2 is fixedly installed on one side of the inner wall of the modular air conditioning unit 1. The air outlet of the centrifugal fan 2 is connected to the side wall of the modular air conditioning unit 1. The centrifugal fan 2 is the power source for guiding the airflow of the modular air conditioning unit 1. The system also includes an air humidification component 3 located inside the modular air conditioning unit 1 near the centrifugal fan 2. A filter component 5 is located inside the modular air conditioning unit 1 away from the centrifugal fan 2. A coil 4 is also installed inside the modular air conditioning unit 1 between the air humidification component 3 and the filter component 5. An air outlet duct 61 is located at one end of the modular air conditioning unit 1, and the air outlet of the centrifugal fan 2 is connected to the air outlet duct 61. The other end of the combined air conditioning unit 1 is provided with an air inlet channel 6. Symmetrical grooves 8 are provided on both sides of the air inlet channel 6 and the air outlet channel 61. Mounting plates 71 are slidably connected to the air inlet channel 6 and the air outlet channel 61 through elastic elements. The mounting plates 71 are located in the corresponding grooves 8. Filter plates 7 are fixedly assembled between the mounting plates 71. The filter plates 7 are used to initially filter the air on the combined air conditioning unit 1. Vibrating elements for vibrating the filter plates 7 are provided outside the air inlet channel 6 and the air outlet channel 61. Through the vibration elements and elastic elements, the filter plates 7 can automatically vibrate in the air inlet channel 6 and the air outlet channel 61, thereby shaking off the dust and impurities attached to the filter plates 7, so that the filter has self-cleaning ability and reduces the workload of manual cleaning and maintenance.

[0024] like Figure 3 As shown, the elastic element includes a guide rod 9 and a spring 10. The guide rod 9 is symmetrically fixedly connected to both sides of the outer wall of the air outlet channel 61 of the air inlet channel 6. The mounting plates 71 on both sides of the filter plate 7 are slidably engaged with the guide rod 9, and the spring 10 is sleeved between the guide rod 9 and the mounting plate 71.

[0025] like Figure 3 and Figure 5As shown, the oscillating component includes a motor 11 and a cam 12. The motor 11 is fixedly installed on the outer wall of the air inlet channel 6 and the air outlet channel 61. The cam 12 is fixedly connected to the output shaft of the motor 11. The cam 12 and the mounting plate 71 on the same side of the filter screen 7 are in contact with each other. When the motor 11 drives the cam 12 to rotate, the cam 12 will intermittently contact and squeeze the mounting plate 71 on the filter screen 7, so that the filter screen 7 and the mounting plate 71 slide in the groove 8 of the air inlet channel 6 or the air outlet channel 61 under the guidance of the guide rod 9 and the compression spring 10. When the cam 12 disengages from the mounting plate 71, the filter screen 7 quickly resets under the action of the spring 10 and collides with the edge of the groove 8. The filter screen 7 will vibrate and shake off the dust on it.

[0026] like Figure 5 As shown, rubber blocks 13 are fixedly installed on both sides of the filter plate 7 near the slide groove 8 of the air inlet channel 6. The rubber blocks 13 are located in the corresponding slide grooves 8 of the air inlet channel 6 and the air outlet channel 61. The rubber blocks 13 are used to reduce the impact force of the filter plate 7, reduce vibration and noise, and improve the service life of the filter plate 7.

[0027] like Figure 3 and Figure 4 As shown, an electric push rod 14 is fixedly installed on the outer wall of the air inlet channel 6, and a sliding frame 15 is slidably connected to the inner wall of the air inlet channel 6. The end of the sliding frame 15 slides through the air inlet channel 6 and is connected to the piston rod of the electric push rod 14. A brush 16 is fixedly mounted on the sliding frame 15. The brush head of the brush 16 contacts the filter screen on the corresponding filter screen plate 7. The electric push rod 14 drives the brush 16 to repeatedly brush the filter screen of the filter screen plate 7 through the sliding frame 15, thereby further improving the cleaning effect on the filter screen plate 7.

[0028] like Figure 4 and Figure 6 As shown, a connecting plate 17 is fixedly connected to the sliding frame 15. A fan 18 is fixedly installed at the end of the connecting plate 17 away from the brush 16. The fan 18 faces the brush 16 and is used to assist the brush 16 in cleaning the filter screen of the filter plate 7, thereby cleaning the filter plate 7 efficiently.

[0029] When using this modular air conditioner, the centrifugal fan 2, as the core power source, starts operating. Outside air first enters the main body 1 of the modular air conditioner through the air inlet duct 6. As the air flows through the air inlet duct 6, it undergoes preliminary filtration through the filter screen 7, intercepting larger dust and impurities. The air, preliminarily purified by the filter screen 7, enters the main body 1 of the modular air conditioner and then flows through the filter assembly 5 for further purification. It then undergoes heat exchange (cooling or heating) through the coil 4, and finally flows through the air humidification assembly 3 for humidity adjustment. The treated clean air... The air is drawn in and pressurized by the centrifugal fan 2, and finally discharged through the air outlet duct 61. Within the air outlet duct 61, the air flows again through another filter plate 7, which is fixedly mounted by the mounting plate 71, to capture any small amount of suspended matter that may be generated by internal airflow disturbances or components, ensuring clean air delivery. To achieve self-cleaning of the filter plate 7, the vibrating element begins to operate. The motor 11 of the vibrating element drives the cam 12 to rotate. The rotating cam 12 intermittently contacts and presses the mounting plate 71 on the same side as the filter plate 7. The mounting plate 71 is located in the groove 8 of the air inlet duct 6 or the air outlet duct 61. The cam 12 slides inward and compresses the elastic spring 10. When the cam 12 rotates away from the mounting plate 71, the compressed spring 10 releases energy, pushing the mounting plate 71 and the filter plate 7 to quickly return to their original positions. During the return process of the spring 10, the filter plate 7 will hit the edge of the slide groove 8. At this time, the rubber block 13 acts as a buffer to reduce noise and impact. This strong vibration generated by the periodic drive of the cam 12 and the return of the spring 10 can effectively shake off the dust and impurities accumulated on the filter plate 7, keeping the filter plate 7 unobstructed. To further improve the cleaning effect, the air inlet vent... The electric push rod 14 of channel 6 can drive the sliding frame 15 to reciprocate. The brush 16 fixed on the sliding frame 15 then repeatedly brushes the surface of the filter plate 7 in the air inlet channel 6 to physically remove the stubborn dirt. At the same time, the fan 18 installed on the connecting plate 17 of the sliding frame 15 is started. The airflow generated by the fan 18 is directed towards the brush 16 and the filter plate 7. The airflow of the fan 18 helps to blow away the dust that has been loosened or shaken off by the brush 16, and also enhances the ability of the airflow to penetrate the filter, working together with the brush 16 to achieve more efficient cleaning.
