Regularly cleaning the indoor unit, however, can maintain its normal operation, reduce energy consumption, and effectively extend the unit's lifespan.

[0003] The problem is that the current indoor unit only has one set of filters, which has poor filtration and dust prevention effects and no self-cleaning function, making it easy for dust to accumulate on the filters. Utility Model Content

[0004] This invention solves the technical problem that current indoor units only have one set of filters, resulting in poor filtration and dust prevention, and lack of self-cleaning function, which easily leads to dust accumulation on the filters. This invention improves the filtration and dust prevention effect of the indoor unit by adding a filter assembly to the air outlet. Furthermore, it incorporates a cleaning mechanism and a water spraying mechanism on the filter assembly to effectively clean the dust accumulated on the filter assembly, ensuring the normal operation of the indoor unit.

[0005] To address the aforementioned problems, this utility model provides an indoor unit self-cleaning device. The self-cleaning device is applied to an air conditioner indoor unit, which includes a body and an air outlet. The air outlet is located on the body. The self-cleaning device includes: a filter assembly installed on the body and corresponding to the air outlet; a cleaning mechanism including a first drive assembly, a cleaning brush, and a second drive assembly. The first drive assembly is installed on top of the filter assembly, and the cleaning brush is installed on the second drive assembly, which is connected to the first drive assembly; and a water spraying mechanism installed on the side of the body and corresponding to the cleaning brush. The filter assembly filters the fresh air blown out of the air outlet; the water spraying mechanism sprays water mist onto the cleaning brush; the second drive assembly drives the cleaning brush to rotate, and the first drive assembly moves the second drive assembly and the cleaning brush on the filter assembly to clean it.

[0006] Compared to existing technologies, this technical solution achieves the following advantages: The cleaning mechanism automatically cleans the filter assembly periodically, preventing reduced filtration efficiency due to dust accumulation and thus improving air quality. The indoor unit's cleaning function reduces the frequency and labor intensity of manual cleaning, enhancing user experience and convenience. Simultaneously, the water spray mechanism mists the cleaning brush, enhancing its cleaning effect and effectively removing dust and dirt from the filter. Furthermore, regular filter cleaning reduces equipment malfunctions caused by dust accumulation, extending the air conditioner's lifespan.

[0007] In one possible design, the self-cleaning device also includes a drying mechanism mounted on the filter assembly.

[0008] Compared to existing technologies, this technical solution achieves the following advantages: the drying mechanism quickly dries the filter after cleaning, preventing moisture residue and thus inhibiting the growth of mold and bacteria, further improving air quality. Furthermore, the drying function eliminates the need for users to wait for the filter to dry naturally, allowing for faster resumption of normal air conditioning operation and improving equipment efficiency. Simultaneously, the introduction of the drying mechanism makes the entire self-cleaning process more complete, eliminating concerns about odors or health issues caused by a damp filter, thus increasing user satisfaction.

[0009] In one possible design, the drying mechanism includes: a mounting plate connected to the bottom of the filter assembly; a dryer and an air supply duct connected to the air supply duct, and the dryer and air supply duct are mounted on the mounting plate; and several air nozzles connected to the air supply duct, with each air nozzle corresponding to the filter assembly.

[0010] Compared with existing technologies, the technical advantages of this solution are as follows: By combining the dryer with the air duct, hot air can be quickly generated and evenly blown onto the filter assembly through multiple air nozzles, achieving a highly efficient drying effect and shortening the drying time of the filter. The multiple air nozzles ensure that the hot air can evenly cover all parts of the filter, avoiding moisture residue caused by uneven drying in certain areas and improving the drying effect. Furthermore, the efficient air supply and drying setup can complete the drying process in a shorter time, thereby reducing energy consumption and improving the economic efficiency of the equipment. At the same time, integrating the dryer, air duct, and air nozzles onto the mounting plate simplifies the equipment structure, reduces space occupation, and improves the aesthetics and practicality of the overall design.

[0011] In one possible design, the filter assembly includes a dust cover and a filter screen, with the dust cover installed at the air outlet and the filter screen installed on the dust cover corresponding to the air outlet; wherein, the first drive assembly can drive the cleaning brush on the filter screen to move in a direction closer to or away from the water spraying mechanism.

[0012] Compared to existing technologies, the technical benefits of this solution are as follows: The dust cover effectively prevents external dust and impurities from entering the indoor unit, reducing filter contamination and extending filter lifespan and cleaning cycles. The combined design of the filter and dust cover simplifies cleaning, allowing users to easily disassemble and clean the filter, improving maintenance convenience. Furthermore, the dust cover reduces dust accumulation, maintaining filter permeability and improving airflow efficiency, ensuring high performance during operation. Simultaneously, the first drive component moves the cleaning brush across the filter, ensuring coverage of all areas and enhancing cleaning comprehensiveness and effectiveness.

[0013] In one possible design, the first drive assembly includes: a connecting frame mounted on top of the filter assembly; a drive shaft mounted through the connecting frame, and a second drive assembly sleeved on the drive shaft; and a first drive motor disposed at the end of the drive shaft. The first drive motor drives the drive shaft to rotate, thereby enabling the second drive assembly and the cleaning brush to move along the drive shaft in a direction close to or away from the first drive motor.

[0014] Compared with existing technologies, the technical advantages achieved by this solution are as follows: The first drive motor directly drives the transmission shaft to rotate, providing stable and powerful force, enabling the cleaning brush to move efficiently on the filter screen and improving cleaning efficiency. Simultaneously, the transmission shaft allows the second drive assembly and the cleaning brush to move towards or away from the first drive motor, increasing the cleaning brush's range of motion and ensuring coverage of all areas of the filter screen. Furthermore, the connection frame and transmission shaft design simplify the drive assembly structure, reduce unnecessary parts, lower the failure rate, and improve the reliability of the self-cleaning device.

[0015] In one possible design, the second drive assembly includes a movable base, a movable frame, and a connecting block; the movable base is fitted onto the drive shaft; one end of the movable frame is connected to the movable base, and the other end is connected to the connecting block; wherein, the cleaning brush is movably mounted on the connecting block.

[0016] Compared to existing technologies, the technical advantages of this solution are as follows: The combination of the movable base, the moving frame, and the connecting block allows the cleaning brush to move flexibly in different positions, adapting to various cleaning needs and improving the comprehensiveness and effectiveness of cleaning. The movable base, fitted onto the drive shaft, provides more stable support, reducing brush wobbling during movement and ensuring consistent cleaning results. Simultaneously, the moving frame simplifies and streamlines the brush's movement mechanism, reducing complex transmission structures, lowering the failure rate, and improving device reliability. Furthermore, the connecting block facilitates the installation and removal of the cleaning brush, allowing users to easily replace and maintain it, thus enhancing the device's maintainability.

[0017] In one possible design, a limiting groove is provided on the inner side of the connecting frame, and a limiting block is connected to the movable base; wherein, when the drive shaft drives the movable base to move, the limiting block moves with the movable base within the limiting groove.

[0018] Compared with existing technologies, the technical advantages of this solution are as follows: The limiting groove effectively restricts the movement range of the movable base, ensuring that the movement of the cleaning brush on the filter screen does not exceed the predetermined range, thereby preventing damage to the equipment or affecting the cleaning effect. Furthermore, by limiting the movement of the movable base, mechanical failures or accidents caused by excessive movement are reduced, improving the safety and reliability of the equipment. The following movement of the limiting block within the limiting groove provides more stable support, reducing the wobbling of the cleaning brush during movement and ensuring the stability of the cleaning brush's movement.

[0019] In one possible design, a second drive motor is installed inside the connecting block, and the second drive motor is connected to the cleaning brush via a rotating shaft; wherein, the second drive motor drives the rotating shaft to rotate, thereby driving the cleaning brush to rotate.

[0020] Compared to existing technologies, this technical solution achieves the following advantages: The second drive motor directly drives the rotating shaft, enabling the cleaning brush to rotate at a higher speed, thereby improving its ability to remove dirt and dust and enhancing the cleaning effect. Furthermore, by adjusting the speed of the second drive motor, different cleaning modes can be achieved, such as quick cleaning and fine cleaning, meeting the cleaning requirements of different scenarios and needs. The rotational motion of the cleaning brush can more effectively cover the surface of the filter screen, reducing cleaning time, improving overall cleaning efficiency, and lowering user maintenance costs. Simultaneously, the direct connection between the motor and the rotating shaft reduces intermediate transmission components, lowering the failure rate and improving the overall reliability and durability of the equipment.

[0021] In one possible design, the water spraying mechanism includes: a water storage tank and a water pump pipe, one end of which is located inside the water storage tank and the other end of which passes through the water storage tank and is located outside; a water pump and a water delivery pipe, which are installed in the water storage tank and connected to the water pump pipe and the water delivery pipe; a water spraying pipe and an atomizing nozzle, which are installed in the water spraying pipe and connected to the water delivery pipe; wherein, the water spraying pipe is installed on the side of the water storage tank facing the cleaning brush, and the atomizing nozzle is capable of spraying water mist onto the cleaning brush.

[0022] Compared to existing technologies, this technical solution achieves the following effects: the atomizing nozzle sprays water mist onto the cleaning brush, forming a uniform water mist coverage, enhancing the lubrication of the cleaning brush during the cleaning process, improving cleaning efficiency, and more effectively removing dirt. Furthermore, the atomizing nozzle atomizes water into tiny droplets, reducing water consumption while ensuring cleaning effectiveness, thus achieving water conservation. The spray pipe design ensures that the water mist is evenly sprayed onto the cleaning brush, avoiding cleaning blind spots caused by uneven brush wetting and improving the comprehensiveness of cleaning. The design of the water pump and water delivery pipe ensures a stable water supply, avoiding poor cleaning results due to insufficient water supply and improving equipment reliability. Simultaneously, integrating the spraying mechanism into the water storage tank saves equipment space, making the overall design more compact and improving the aesthetics and practicality of the device.
