Description

Technical Field

[0001] This application relates to the technical field of air conditioning equipment, and more particularly to an indoor air conditioning unit. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow within a building or structure. To meet the needs of daily life, some air conditioners have a fresh air function, which can transfer outdoor air into the room.

[0003] Air conditioners typically contain filters to purify the air. Currently, with the implementation of dual-carbon policies and increased demands for a healthy lifestyle, the cleaning of air conditioner filters has become a pressing issue. If air conditioner filters are not cleaned regularly, they accumulate a large amount of dust and bacteria. This not only affects the air conditioner's efficiency and increases energy consumption, but may also negatively impact human health, such as causing respiratory illnesses.

[0004] Therefore, existing technologies typically employ a cleaning module to clean the filter. The cleaning module includes a cleaning brush that contacts and cleans the filter.

[0005] However, in existing technologies, the dust removed during cleaning is usually collected in a collection box, which users need to frequently remove and empty, affecting the user experience. Utility Model Content

[0006] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0007] Therefore, this application aims to provide an air conditioner indoor unit in which a cleaning module sweeps dust from the filter screen into a dust collection box. A pushing component of the cleaning structure moves a cleaning block, which automatically cleans the dust from the dust collection box and discharges it through the dust exhaust pipe, eliminating the need for frequent manual disassembly and cleaning of the dust collection box. This design significantly reduces the user's maintenance workload and improves the ease of use of the air conditioner. Simultaneously, the automatic cleaning function keeps the dust collection box clean, preventing odors or secondary pollution caused by dust accumulation, thus improving the hygiene performance and lifespan of the air conditioner.

[0008] To achieve the above objectives, this utility model provides an indoor air conditioning unit, comprising:

[0009] The casing has an air conditioning inlet at the top;

[0010] An indoor heat exchanger is disposed inside the housing;

[0011] An indoor fan is disposed inside the housing; the indoor fan causes airflow to enter the housing through the air conditioner inlet, and after heat exchange via the indoor heat exchanger, it is output to the room;

[0012] A filter module is disposed within the housing, and the filter module includes a filter screen;

[0013] A cleaning module, disposed within the housing, is used to clean the filter screen;

[0014] A dust collection box is disposed inside the housing and used to collect dust removed by the cleaning module; the dust collection box is connected to a dust discharge pipe; the dust discharge pipe is connected to the outside of the housing;

[0015] A cleaning structure, comprising a cleaning block and a pushing component, wherein the pushing component is used to drive the cleaning block to reciprocate inside the dust collection box, so that the cleaning block moves closer to or away from the dust discharge pipe;

[0016] The cleaning structure is used to clean the dust in the dust collection box to the dust discharge pipe, so that the dust in the dust collection box can be discharged through the dust discharge pipe.

[0017] In this technical solution, the cleaning module sweeps dust from the filter into the dust collection box. A pushing component in the cleaning structure moves a cleaning block, which automatically empties the dust from the dust collection box into the exhaust pipe, eliminating the need for frequent manual disassembly and cleaning of the dust collection box. This design significantly reduces user maintenance workload and improves the ease of use of the air conditioner. Simultaneously, the automatic cleaning function keeps the dust collection box clean, preventing odors or secondary pollution caused by dust accumulation, thus enhancing the air conditioner's hygiene performance and lifespan.

[0018] In some embodiments of this application, the pushing member includes a screw and a cleaning drive member. The screw is rotatably connected to the dust collection box, and the cleaning drive member is used to drive the screw to rotate. The cleaning block is provided with a threaded portion that is threadedly connected to the screw.

[0019] In this technical solution, the cleaning drive unit rotates the screw. Because the cleaning block is limited by the dust collection box and cannot rotate, the cleaning block, threadedly connected to the screw, moves along the screw's axial direction. This structure not only achieves precise control of the cleaning block but also provides stable power transmission through threaded drive. The reciprocating movement of the cleaning block effectively concentrates dust and pushes it into the dust discharge pipe, ensuring the efficiency and reliability of dust cleaning and further improving the performance of the automatic cleaning function. Compared to the cleaning block being fitted onto the screw, this design allows for easier separation of the cleaning block from the screw. When the cleaning block is damaged or jammed, it can be removed for maintenance.

[0020] In some embodiments of this application, the pushing member includes a screw and a cleaning drive member, the screw is rotatably connected to the dust collection box, and the cleaning drive member is used to drive the screw to rotate; the cleaning block is sleeved and threadedly connected to the screw.

[0021] In this technical solution, the cleaning drive unit rotates the screw. Because the cleaning block is limited by the dust collection box and cannot rotate, the cleaning block, which is threadedly connected to the screw, moves along the screw's axial direction. This structure not only achieves precise control of the cleaning block but also provides stable power transmission through the threaded drive. The reciprocating movement of the cleaning block effectively concentrates dust and pushes it into the dust discharge pipe, ensuring the high efficiency and reliability of dust cleaning and further improving the performance of the automatic cleaning function.

[0022] In some embodiments of this application, one end of the dust discharge pipe connected to the dust collection box is located at one end in the direction of movement of the cleaning block.

[0023] In this technical solution, the cleaning block directly pushes dust towards the dust discharge pipe during its movement, improving dust removal efficiency. This layout optimizes the use of space inside the dust collection box, allowing the cleaning structure to operate more efficiently and further enhancing the performance of the automatic cleaning function.

[0024] In some embodiments of this application, the cleaning block is arranged with an inclined surface on the side away from the dust exhaust pipe, and the inclined surface is inclined from bottom to top towards the side closer to the dust exhaust pipe.

[0025] In this technical solution, as the cleaning block moves away from the dust exhaust pipe, dust comes into contact with it and flows across the inclined surface to the side of the cleaning block closest to the dust exhaust pipe. The next time the cleaning block moves towards the dust exhaust pipe, the dust is pushed towards the pipe and discharged. This prevents dust from accumulating on the side of the cleaning block away from the dust exhaust pipe, thus improving dust cleaning efficiency.

[0026] In some embodiments of this application, the pushing component is a cylinder, and the fixed end and the output end of the cylinder are respectively connected to the cleaning block and the dust collection box.

[0027] In this technical solution, the extension and retraction of the cylinder can quickly and accurately move the cleaning block, achieving efficient dust removal. Compared with screw drives, the cylinder structure is simpler and has a faster response speed, enabling dust removal and discharge to be completed in a short time, further improving the efficiency of the automatic cleaning function and the user experience.

[0028] In some embodiments of this application, the filtering module includes:

[0029] The first steering rod is located at one end of the air conditioning inlet;

[0030] The second steering rod is located at the end of the air conditioner inlet that is away from the first steering rod; the filter is annular and is fitted over the first steering rod and the second steering rod.

[0031] In the technical solution, the rotation of the filter screen facilitates cleaning of the filter screen by the cleaning module.

[0032] In some embodiments of this application, the cleaning module includes:

[0033] The first drive component is used to drive the filter screen to rotate;

[0034] A cleaning brush is positioned below the filter.

[0035] In the technical solution, the filter screen is rotated by the first drive component, and the cleaning brush in contact with the filter screen can directly clean the surface of the filter screen.

[0036] In some embodiments of this application, the cleaning module further includes:

[0037] A toothed comb, which is disposed within the housing;

[0038] The second drive component is used to drive the cleaning brush to rotate and contact the comb.

[0039] In this technical solution, the cleaning brush interacts with the comb as it rotates. The comb removes dust, hair, and other impurities adhering to the brush, preventing it from losing its cleaning effectiveness due to accumulated debris. The second drive component rotates the cleaning brush in conjunction with the comb, ensuring the brush maintains excellent cleaning power throughout the filter cleaning process. This guarantees a long-lasting and stable cleaning effect, effectively solving the problem of decreased cleaning efficiency caused by prolonged contamination of traditional cleaning brushes. This maintains the efficient operation of the air conditioner indoor unit's filtration system and ensures consistently excellent indoor air quality.

[0040] In addition, this application also provides an air conditioner indoor unit, which includes:

[0041] The casing has an air conditioning inlet at the top;

[0042] An indoor heat exchanger is disposed inside the housing;

[0043] An indoor fan is disposed inside the housing; the indoor fan causes airflow to enter the housing through the air conditioner inlet, and after heat exchange via the indoor heat exchanger, it is output to the room;

[0044] A filter module is disposed within the housing, and the filter module includes a filter screen;

[0045] A cleaning module, disposed within the housing, is used to clean the filter screen;

[0046] A dust collection box is disposed inside the housing and is used to collect the dust removed by the cleaning module; the dust collection box is connected to a dust discharge port;

[0047] A cleaning structure, comprising a cleaning block and a pushing component, wherein the pushing component is used to drive the cleaning block to reciprocate inside the dust collection box, so that the cleaning block moves closer to or away from the dust discharge port;

[0048] The cleaning structure is used to clean the dust in the dust collection box to the dust discharge port, so that the dust in the dust collection box can be discharged through the dust discharge port.

[0049] In this technical solution, the cleaning module sweeps dust from the filter into the dust collection box. A pushing component in the cleaning structure moves a cleaning block, which automatically empties the dust from the dust collection box into the exhaust port, eliminating the need for frequent manual disassembly and cleaning of the dust collection box. This design significantly reduces user maintenance workload and improves the ease of use of the air conditioner. Simultaneously, the automatic cleaning function keeps the dust collection box clean, preventing odors or secondary pollution caused by dust accumulation, thus enhancing the air conditioner's hygiene performance and lifespan.

[0066] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0067] In this application, the indoor unit of the air conditioner includes a casing, an indoor heat exchanger, and an indoor fan. The indoor heat exchanger and the indoor fan are disposed inside the casing. Indoor air enters the casing and comes into contact with the indoor heat exchanger. After heat exchange between the indoor heat exchanger and the air, the heat-exchanged air is output to the room under the action of the indoor fan, thereby achieving the regulation of the indoor temperature.

[0068] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0069] Please refer to all the accompanying drawings. In one illustrative embodiment of the indoor unit of the air conditioner of this utility model, the indoor unit includes: the indoor unit includes a housing 100, and an air conditioning air inlet is provided on the top of the housing 100 for air to pass through and enter the housing 100.

[0070] In some embodiments, the indoor unit of the air conditioner includes an indoor heat exchanger disposed inside the housing 100. The indoor heat exchanger is a key component for heat exchange in the air conditioning system. In cooling mode, refrigerant evaporates within the heat exchanger, absorbing heat from the surrounding air.

[0071] In some embodiments, the indoor unit of the air conditioner includes an indoor fan disposed inside the housing 100; the indoor fan causes airflow to enter the housing 100 through the air conditioner air inlet, and after heat exchange by the indoor heat exchanger, it is output to the room.

[0072] In some embodiments, the indoor unit of the air conditioner includes a filter module disposed within the housing 100. The filter module of the air conditioner is mainly used to purify the air entering the air conditioner and intercept impurities such as dust, pollen, and hair in the air, playing an important role in the normal operation of the air conditioner and the improvement of indoor air quality.

[0073] In some embodiments, the filter module includes a first steering rod 201, a second steering rod 202, and a filter screen 200. The first steering rod 201 is disposed within the housing 100 and located at one end of the air conditioning inlet. The second steering rod 202 is disposed within the housing 100 and located at the end of the air conditioning inlet away from the first steering rod 201. The filter screen 200 is annular and is fitted with the first steering rod 201 and the second steering rod 202. The first steering rod 201 and the second steering rod 202 located at both ends of the air conditioning inlet together provide support for the filter screen 200. The first steering rod 201 and the second steering rod 202 pull the two ends of the filter screen 200, allowing the annular filter screen 200 to be stretched and opened, maintaining a relatively flat and stable filtration plane, preventing the filter screen 200 from collapsing, wrinkling, or other phenomena, ensuring that air can pass through all parts of the filter screen 200 without obstruction, and maintaining a stable and efficient filtration effect.

[0074] In some embodiments, the indoor unit of the air conditioner includes a cleaning module disposed within the housing 100. The cleaning module is used to clean the filter 200. The cleaning module has multiple technical benefits, including improving cleaning efficiency, extending the lifespan of the filter 200, and improving air quality. It also maintains air conditioning performance, enhances user experience, and promotes environmental protection and energy conservation. These effects collectively bring users a more comfortable, healthy, and convenient air conditioning experience.

[0075] In some embodiments, the cleaning module includes a first drive assembly and a cleaning brush 300. The first drive assembly is used to rotate the filter 200. The cleaning brush 300 is disposed below the filter 200.

[0076] Through the above scheme, indoor air enters the housing 100 through the air conditioner inlet under the action of the indoor fan. Dust and other impurities in the air are filtered by the filter 200 as they pass through the air conditioner inlet. This protects components such as the indoor heat exchanger, improves indoor air quality, reduces maintenance costs, and extends the service life of the equipment. Under the action of the first drive component, the filter 200 is rotated, at which time the cleaning brush 300 cleans the outer surface of the filter 200.

[0077] In some embodiments, the first driving assembly includes a driving brush and a first driving member, with the peripheral wall of the driving brush abutting against the filter screen 200. The first driving member drives the driving brush to rotate. The filter screen 200 is rotated through frictional contact between the driving brush and the filter screen 200. This driving method is simple, direct, stable, and reliable, ensuring that the filter screen 200 rotates in a predetermined manner and speed during the cleaning process. This allows all parts of the filter screen 200 to pass through the cleaning area between the cleaning brush 300 and the cleaning plate in an orderly manner, achieving comprehensive cleaning of the filter screen 200. This ensures that the filter screen 200 will not affect its overall filtration performance due to inadequate local cleaning, maintaining a stable air filtration efficiency of the indoor air conditioning unit and reducing problems such as increased energy consumption caused by filter screen 200 clogging.

[0078] In some embodiments, a dust collection box 500 is also provided inside the housing 100, which is used to collect the dust cleaned by the cleaning module.

[0079] In some embodiments, the dust collection box 500 is located below the cleaning brush 300. The dust collection box 500 collects dust, dirt, and other impurities that fall from the filter 200 during the cleaning process. Timely dust collection prevents secondary re-entrainment within the housing 100, avoiding secondary contamination of the cleaned filter 200 and other components, and ensuring a clean and hygienic internal environment for the air conditioner indoor unit. Simultaneously, the dust collection box 500 facilitates regular dust removal, simplifies maintenance procedures, improves maintenance efficiency, and makes the maintenance of the air conditioner indoor unit more convenient and efficient. This helps maintain the overall stability and reliability of the equipment, extends its service life, and enhances the user experience.

[0080] In some embodiments, the dust collection box 500 is provided with a dust discharge port, which connects the inside and outside of the dust collection box 500.

[0081] In some embodiments, the dust collection box 500 is connected to a dust discharge pipe 501; the dust discharge pipe 501 is connected to a dust discharge port and to the outside of the housing 100. The indoor unit of the air conditioner also includes a cleaning structure, which includes a cleaning block 130 and a pushing member. The pushing member is used to drive the cleaning block 130 to reciprocate inside the dust collection box 500 so that the cleaning block 130 moves closer to or away from the dust discharge pipe 501; the cleaning structure is used to clean the dust in the dust collection box 500 to the dust discharge pipe 501 so that the dust in the dust collection box 500 is discharged through the dust discharge pipe 501.

[0082] Through the above solution, the cleaning module sweeps the dust on the filter 200 into the dust collection box 500. The pushing component of the cleaning structure drives the cleaning block 130 to move, and the cleaning block 130 automatically cleans the dust in the dust collection box 500 and discharges it through the dust exhaust pipe 501, eliminating the need for frequent manual disassembly and cleaning of the dust collection box 500. This design greatly reduces the user's maintenance workload and improves the convenience of using the air conditioner. At the same time, the automatic cleaning function keeps the dust collection box 500 clean, avoiding odors or secondary pollution caused by dust accumulation, thus improving the hygiene performance and service life of the air conditioner.

[0083] In some embodiments, the dust discharge port is located on the inner bottom wall of the dust collection box 500, so one end of the dust discharge pipe 501 is connected to the bottom wall of the dust collection box 500. Dust can be discharged under gravity when it moves to the dust discharge port, making it easy to clean.

[0084] In some embodiments, the dust discharge port is located on the side wall of the dust collection box 500 at one end of the moving direction of the cleaning block 130, and the dust discharge port is close to the inner bottom wall of the dust collection box 500. During the movement of the cleaning block, dust can be directly pushed towards the dust discharge port, and the dust is more easily discharged through the dust discharge port under the action of gravity.

[0085] In some embodiments, the driving component includes a screw 800 and a cleaning drive component 900. The screw 800 is rotatably connected within the dust collection box 500, and the cleaning drive component 900 drives the screw 800 to rotate. The cleaning block 130 is provided with a threaded portion 140 that is threadedly connected to the screw 800. The cleaning drive component 900 drives the screw 800 to rotate, but because the cleaning block 130 is limited by the dust collection box 500 and cannot rotate, the cleaning block 130 threadedly connected to the screw 800 moves along the axial direction of the screw 800. This structure not only achieves precise control of the cleaning block 130 but also provides stable power transmission through threaded drive. The reciprocating movement of the cleaning block 130 can effectively concentrate dust and push it into the dust discharge pipe 501, ensuring the high efficiency and reliability of dust cleaning and further improving the performance of the automatic cleaning function. Compared to the screw 800 mounted on the cleaning block 130, the cleaning block 130 can be separated from the screw 800 more easily. When the cleaning block 130 is damaged or stuck, it can be removed for maintenance.

[0086] In some embodiments, the screw 800 is arranged along the length of the dust collection box 500, and its two ends are rotatably connected to the dust collection box 500. A cleaning drive 900 is disposed outside the dust collection box 500, and drives the screw 800 to rotate. By placing the cleaning drive 900 outside the dust collection box 500, direct contact between the drive and dust inside the dust collection box 500 can be avoided, thereby reducing wear and contamination of the drive by dust and extending the service life of the cleaning drive 900.

[0087] In some embodiments, the cleaning drive 900 can be a motor or electric motor. The motor or electric motor can precisely control the rotational speed and direction of the screw 800 or other transmission components, thereby realizing the reciprocating motion of the cleaning block 130 and ensuring the efficiency and reliability of dust cleaning.

[0088] In some embodiments, the screw 800 can be a reciprocating screw 800, and the reciprocating movement of the cleaning block 130 can be achieved by the unidirectional rotation of the screw 800. That is, the cleaning drive 900 does not need to switch between forward and reverse rotation to achieve the reciprocating motion of the cleaning block 130. This reduces the requirements for the control precision of the drive component and reduces the mechanical wear and failure risks that may be caused by frequent switching between forward and reverse rotation. At the same time, this design makes power transmission more efficient, reduces energy loss, and improves the overall operating efficiency of the system.

[0089] In some embodiments, the length direction of the screw 800 is arranged along the width direction of the dust collection box 500.

[0090] In some embodiments, the threaded portion 140 is integrally formed with the cleaning block 130, and the threaded portion 140 is fitted and threadedly connected to the screw 800. The integral design simplifies the manufacturing process, reduces production costs, and also facilitates the installation and maintenance of the cleaning block 130.

[0091] In some embodiments, the driving component includes a screw 800 and a cleaning drive 900. The screw 800 is rotatably connected within the dust collection box 500, and the cleaning drive 900 drives the screw 800 to rotate. A cleaning block 130 is sleeved on and threadedly connected to the screw 800. The cleaning drive 900 drives the screw 800 to rotate, but because the cleaning block 130 is limited by the dust collection box 500 and cannot rotate, the cleaning block 130, threadedly connected to the screw 800, moves along the axial direction of the screw 800. This structure not only achieves precise control of the cleaning block 130 but also provides stable power transmission through threaded drive. The reciprocating movement of the cleaning block 130 effectively concentrates dust and pushes it into the dust discharge pipe 501, ensuring the efficiency and reliability of dust cleaning and further improving the performance of the automatic cleaning function.

[0092] In some embodiments, the dust collection box 500 includes a separate receiving cavity 600, within which the screw 800 is disposed, thereby preventing dust from affecting the normal rotation of the screw 800. Furthermore, to ensure the connection between the screw 800 and the cleaning block 130, a groove 700 is provided on the receiving cavity 600, the groove 700 being parallel to the length of the screw 800. If a threaded portion 140 is provided, the threaded portion 140 passes through the groove 700 and is threadedly connected to the screw 800. Alternatively, a slider portion may pass through the groove 700.

[0093] In some embodiments, the cleaning drive 900 is connected to the screw 800 via a gear set. The gear set includes a first cleaning gear 110 and a second cleaning gear 120. The first cleaning gear 110 is coaxially connected to one end of the screw 800, and the second cleaning gear 120 meshes with the first cleaning gear 110. The cleaning drive 900 is connected to the second cleaning gear 120. The cleaning drive 900 drives the second cleaning gear 120 to rotate, and the second cleaning gear 120 drives the first cleaning gear 110 and the screw 800 to rotate. With this design, the cleaning drive 900 can be omitted from one end of the screw 800, thereby shortening the front-to-back dimensions of the air conditioner.

[0094] In some embodiments, the end of the dust exhaust pipe 501 connected to the dust collection box 500 is located at one end in the direction of movement of the cleaning block 130. During the pushing process, the cleaning block 130 can directly push dust towards the dust exhaust pipe 501, improving the efficiency of dust discharge. This layout optimizes the space utilization inside the dust collection box 500, enabling the cleaning structure to work more efficiently and further enhancing the performance of the automatic cleaning function.

[0095] In some embodiments, the cleaning block 130 is arranged with an inclined surface on the side away from the dust exhaust pipe 501, and the inclined surface slopes upwards towards the side closer to the dust exhaust pipe 501. When the cleaning block 130 moves away from the dust exhaust pipe 501, dust comes into contact with it and flows across the inclined surface to the side of the cleaning block 130 closer to the dust exhaust pipe 501. The next time the cleaning block 130 moves towards the dust exhaust pipe 501, the dust is pushed towards the dust exhaust pipe 501 and discharged from the dust exhaust pipe 501. This avoids dust accumulation on the side of the cleaning block 130 away from the dust exhaust pipe 501, improving the efficiency of dust cleaning.

[0096] In some embodiments, the actuating element is a cylinder, with its fixed end and output end connected to the cleaning block 130 and dust collection box 500, respectively. The extension and retraction of the cylinder can quickly and accurately move the cleaning block 130, achieving efficient dust cleaning. Compared with the screw drive 800, the cylinder structure is simpler, has a faster response speed, and can complete the cleaning and discharge of dust in a short time, further improving the efficiency of the automatic cleaning function and the user experience.

[0097] In some embodiments, when the actuating element is a cylinder, the cylinder includes a cylinder body and a push rod, with the push rod sliding within the cylinder body. The cylinder body is fixed to the inner wall of the dust collection box 500, and the push rod is connected to the cleaning block 130. Compared to the screw drive 800, the cylinder structure is simpler, has a faster response speed, and can complete the cleaning and discharge of dust in a short time, further improving the efficiency of the automatic cleaning function and the user experience. In another embodiment, the cylinder body is fixed to the cleaning block 130, and the push rod is connected to the dust collection box 500.

[0098] In some embodiments, the cleaning module further includes a comb 400 and a second drive assembly, the second drive assembly being used to drive the cleaning brush 300 to rotate and contact the comb 400. The cleaning brush 300 interacts with the comb 400 as it rotates. The comb 400 can comb away dust, hair, and other impurities adhering to the cleaning brush 300, preventing the cleaning brush 300 from losing its cleaning effect due to impurity accumulation. By driving the cleaning brush 300 to rotate and cooperate with the comb 400 through the second drive assembly, the cleaning brush 300 can maintain good cleaning ability throughout the cleaning process of the filter 200, ensuring a long-lasting and stable cleaning effect on the filter 200. This effectively solves the problem of decreased cleaning efficiency of traditional cleaning brushes 300 due to self-contamination after prolonged use, maintaining the efficient operation of the air conditioner indoor unit filtration system and ensuring consistently excellent indoor air quality.

[0099] In some embodiments, the second drive assembly includes a second drive member for driving the cleaning brush 300 to rotate, providing a power source for the interaction between the cleaning brush 300 and the comb 400, ensuring that the cleaning brush 300 can rotate at a predetermined speed and direction, and making the combing action between it and the comb 400 stable and reliable. A stable power supply ensures the continuity of the cleaning effect of the cleaning brush 300 during the cleaning process of the filter 200, avoiding situations where the cleaning brush 300 cannot work properly or the cleaning effect is poor due to insufficient or unstable power. This maintains the normal operation of the air conditioner indoor unit's filtration system, ensuring that the indoor air meets the expected purification standards after being filtered by the filter 200, and improving the overall performance and reliability of the air conditioner indoor unit.

[0100] In addition, this application also provides an air conditioner indoor unit, which differs from the above in that it does not have a dust exhaust pipe 501, but only a dust exhaust port.

[0101] The cleaning structure is used to clean the dust in the dust collection box 500 to the dust discharge port, so that the dust in the dust collection box 500 can be discharged through the dust discharge port.

[0102] Through the above solution, the cleaning module sweeps the dust on the filter 200 into the dust collection box 500. The pushing component of the cleaning structure drives the cleaning block 130 to move, and the cleaning block 130 automatically cleans the dust in the dust collection box 500 and discharges it through the dust outlet, eliminating the need for frequent manual disassembly and cleaning of the dust collection box 500. This design greatly reduces the user's maintenance workload and improves the convenience of using the air conditioner. At the same time, the automatic cleaning function keeps the dust collection box 500 clean, avoiding odors or secondary pollution caused by dust accumulation, thus improving the hygiene performance and service life of the air conditioner.

[0103] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
