[0002] As people's living standards improve, air conditioners have become ubiquitous in daily life, leading to increasingly higher requirements for their overall performance, especially their cleaning and dust removal functions.

[0003] After prolonged use, dust accumulates on the indoor unit's filter, which can easily breed bacteria and lead to a decline in indoor air quality. Currently, air conditioner cleaning is done manually, requiring the disassembly of various components for cleaning, followed by reassembly – a time-consuming and labor-intensive process.

[0004] Some air conditioners are equipped with automatic brushes to clean the filter, but this is not enough to remove the sticky dust that accumulates on the filter in humid air. Summary of the Invention

It divides the filter track into a track air inlet section and a track indoor heat exchanger section, with the track indoor heat exchanger section adhering to the surface of the indoor heat exchanger. This design allows the filter to directly contact the indoor heat exchanger surface as it moves to the track indoor heat exchanger section. By controlling the frosting and defrosting process of the indoor heat exchanger, the filter adhering to the indoor heat exchanger surface can be washed and cleaned. This self-cleaning mechanism utilizes the air conditioner's own cooling and heating functions, eliminating the need for additional cleaning equipment or manual intervention, reducing maintenance costs and user operational complexity.

[0067] Background Introduction

[0068] As people's living standards improve, air conditioners have become ubiquitous in daily life, leading to increasingly higher requirements for their overall performance, especially their cleaning and dust removal functions.

[0069] After prolonged use, dust accumulates on the indoor unit's filter, which can easily breed bacteria and lead to a decline in indoor air quality. Currently, air conditioner cleaning is done manually, requiring the disassembly of various components for cleaning, followed by reassembly – a time-consuming and labor-intensive process.

[0070] Some air conditioners are equipped with automatic brushes to clean the filter, but this is not enough to remove the sticky dust that accumulates on the filter in humid air.

[0071] Based on this, such as Figures 1-7 As shown, the first aspect of this application provides a wall-mounted air conditioner indoor unit, characterized in that it includes:

[0072] The body 100 has an air inlet 101 on its top.

[0073] An indoor heat exchanger 200 is located inside the body 100, and an installation space is defined between the indoor heat exchanger 200 and the body 100.

[0074] A filter assembly is installed in the installation space. The filter assembly includes a filter track 300 and a filter 400 that can be driven to move in the filter track 300. The filter track 300 includes a track air inlet section 301 and a track indoor heat exchanger section 303. The track air inlet section 301 is set above the indoor heat exchanger 200 and spaced apart from the indoor heat exchanger 201, and the track indoor heat exchanger section 303 is set on the surface of the indoor heat exchanger 200. The filter 400 is configured such that when the filter is moved into the track indoor heat exchanger section 303, it can be cleaned by the frosting and defrosting of the indoor heat exchanger 200.

[0075] In this embodiment, the filter track 300 is divided into a track air inlet section 301 and a track indoor heat exchanger section 303, with the track indoor heat exchanger section 303 adhering to the surface of the indoor heat exchanger 200. This design allows the filter 400 to directly contact the surface of the indoor heat exchanger 200 when it moves to the track indoor heat exchanger section 303. By controlling the frosting and defrosting process of the indoor heat exchanger 200, the filter 400 adhering to the surface of the indoor heat exchanger 200 can be washed and cleaned. This self-cleaning mechanism utilizes the air conditioner's own cooling and heating functions, requiring no additional cleaning equipment or manual intervention, reducing maintenance costs and user operational complexity. Furthermore, because the filter 400 can more effectively adhere to the surface of the indoor heat exchanger and be washed, dust and bacteria on the filter 400 can be removed more thoroughly, thereby improving indoor air cleanliness and providing users with a healthier living environment.

[0076] Furthermore, in some possible implementations, the track interior heat exchanger section is attached to the surface of the interior heat exchanger 200.

[0077] When the filter screen 400 moves into the indoor heat exchanger section 303 of the track, the filter screen 400 frosts simultaneously with the indoor heat exchanger 200, and defrosts simultaneously with the indoor heat exchanger 200.

[0078] In this way, when the indoor heat exchanger 200 is frosted and then defrosted, the filter screen 400, which has moved to the indoor heat exchanger section 303 on the track, can also be frosted and then defrosted simultaneously, so that the defrosting water after frosting and defrosting can be used to wash and clean the surface of the filter screen 400.

[0079] Furthermore, in some possible implementations, such as Figures 1-3 As shown, the indoor heat exchanger 200 includes an indoor heat exchanger top near the air inlet 101, a first inclined heat exchange section 201 extending obliquely downward from the indoor heat exchanger top towards the front side of the body 100, and a second inclined heat exchange section 202 extending obliquely downward from the indoor heat exchanger top towards the rear side of the body 100.

[0080] The track-mounted indoor heat exchanger section 303 is attached to the first inclined heat exchange section 201 and / or attached to the second inclined heat exchange section 202.

[0081] Since the filter screen 400 can be attached to the inclined first and / or second inclined heat exchange sections 201, this increases the contact area between the filter screen 400 and the surface of the indoor heat exchanger 200. This results in better cleaning when the filter screen 400 is washed with water by controlling the defrosting process of the indoor heat exchanger 200. At the same time, since the filter screen 400 can be attached to the inclined first and / or second inclined heat exchange sections 201, it is easier to drain the cleaning water after washing when the filter screen 400 is washed with water by the defrosting operation of the indoor heat exchanger 200, thereby avoiding the residue of cleaning water on the surface of the indoor heat exchanger 200.

[0082] Furthermore, in some possible implementations, such as Figures 1-3 As shown, the filter track 300 also includes a track transition section 302 connecting the track air inlet section 301 and the track indoor heat exchanger section 303. The track transition section 302 is configured to avoid the air inlet 101.

[0083] The indoor unit of the air conditioner also includes a cleaning brush assembly 500, which is used to clean the filter 400 that moves into the track transition section 302.

[0084] In this embodiment, a track transition section 302 is added between the track air inlet end 301 and the track indoor heat exchanger section 303. This allows the filter screen 400 to pass through a transition area as it moves from the air inlet track section 301 to the indoor heat exchanger track section 303. Within this transition area, the cleaning brush assembly 500 can clean the filter screen, ensuring that the filter screen 400 accumulates as little dust and dirt as possible before reaching the surface of the indoor heat exchanger 200. Simultaneously, because the track transition section 302 is designed to avoid the air inlet 101, the dust that falls off during filter cleaning will not be blown onto other components inside the unit 100 by the airflow entering through the air inlet 101, thereby improving dust collection efficiency.

[0085] Furthermore, in some possible implementations, the track air inlet section 301 extends along the front-rear direction of the body 100, one end of the track transition section 302 is connected to the extended end of the track air inlet section 301, and the other end extends downward toward the body 100, and one end of the track indoor heat exchanger section 303 is connected to the bottom end of the track transition section 302, and the other end extends upward at an angle.

[0086] In this embodiment, by designing the three track sections as described above, the extra space between the indoor heat exchanger 200 and the body 100 can be fully utilized, thereby achieving effective cleaning of the filter screen while avoiding an increase in the size of the body 100.

[0087] Furthermore, in some possible implementations, such as Figures 1-3 As shown, the track transition section 302 is connected to one end of the track air inlet section 301 near the front of the body 100;

[0088] The indoor heat exchanger section 303, which is connected to the bottom of the track transition section 302, is attached to the surface of the inclined first inclined heat exchange section 201.

[0089] In this embodiment, the track transition section 302 is located on the front side of the body 100. This facilitates the disassembly and maintenance of the filter assembly, as well as the cleaning of the dust collection assembly. It is worth noting that, as... Figures 1-3 As shown, the dust collection assembly in this embodiment includes a dust collection box that is detachably connected to the front of the body 100. In this embodiment, by setting the track transition section 302 and the dust collection box on the front of the body 100, when the dust in the dust collection box accumulates to a certain extent, the user or maintenance personnel can more easily remove the dust collection box from the body 100.

[0090] Furthermore, in some possible implementations, such as Figures 1-3As shown, the cleaning brush assembly 500 includes a movable brush 501 rotatably disposed between the track transition section 302 and the body 100. The movable brush 501 has a first position and a second position when rotating. When the movable brush 501 is in the first position, it can clean the filter screen 400 that has moved into the track transition section 302.

[0091] The cleaning brush assembly 500 also includes a fixed brush 502 whose position is fixed, and the movable brush 501 can contact the fixed brush 502 when it is in the second position so as to clean the movable brush 501 by means of the fixed brush 502.

[0092] In this embodiment, a dual-brush cleaning mechanism is achieved in the air conditioner indoor unit by setting a movable brush 501 and a fixed brush 502. In the first position, the movable brush 501 cleans the filter 400, while in the second position, it contacts the fixed brush 502, which cleans the movable brush 501. This design improves cleaning efficiency and effectiveness. The rotation of the movable brush 501 automates the cleaning process of the filter in the track transition section 302, reducing manual intervention and improving cleaning convenience and efficiency. In the second position, the movable brush 501 can self-clean via the fixed brush 502, meaning the cleaning components can achieve self-maintenance without adding complex mechanical structures, reducing maintenance costs and workload.

[0093] Furthermore, in some possible implementations, the indoor unit of the air conditioner also includes;

[0094] The dust collection assembly 600 includes a dust collection box disposed at the bottom of the cleaning brush assembly 500 and having an opening at the top, the dust collection box being used to collect dust after the cleaning brush assembly 500 has been cleaned.

[0095] In this embodiment, by providing a dust collection assembly 600, particularly a dust collection box, dust generated by the cleaning brush assembly 500 during cleaning of the filter 400 can be effectively collected. This helps prevent dust from escaping into the air during the cleaning process, maintaining clean indoor air. It is worth noting that the dust collection box is detachably connected to the main body 100, facilitating subsequent disassembly and assembly by users or maintenance personnel.

[0096] Furthermore, in some possible implementations, the indoor unit of the air conditioner also includes:

[0097] The drive assembly 700 includes a first roller 701 and a second roller 702 that can be driven to rotate.

[0098] The first roller 701 is located at the junction of the track air inlet section 301 and the track transition section 302, and the second roller 702 is located at the junction of the track transition section 302 and the track indoor heat exchanger section 303.

[0099] In this embodiment of the application, by setting the connection position of the first roller 701 and the second roller 702 on the track section, the movement of the filter screen 400 between the track air inlet section 301, the track transition section 302 and the track indoor heat exchanger section 303 can be controlled more precisely, ensuring the correct positioning and movement of the filter screen.

[0100] Specifically, such as Figure 4 and Figure 6 As shown, gears are installed on both sides of the rollers {first roller 701 and second roller 702}, which can mesh with the rack belts on both sides of the flexible filter screen 400, thereby driving the flexible filter screen 400 to move on the filter screen track 300.

[0101] Furthermore, in some possible implementations, such as Figures 1-3 As shown, the indoor unit of the air conditioner also includes:

[0102] Sensor 800 is used to detect and output parameter values ​​that characterize the dirt and clogging status of filter 400;

[0103] The controller is used to control the filter screen 400 to move to the track transition section 302 according to the parameter value and control the cleaning brush assembly 500 to clean the filter screen 400, or to control the filter screen 400 to move to the track indoor heat exchanger section 303 and control the indoor heat exchanger 200 to frost and defrost to wash and clean the filter screen 400 attached to the surface of the indoor heat exchanger 200.

[0104] In this embodiment, sensor 800 detects the dirt and clogging status of filter 400, enabling the indoor air conditioning unit to intelligently determine when cleaning is needed, thus making the cleaning process more automated and intelligent. Specifically, based on the parameter values ​​output by the sensor, the controller can precisely control the filter to move to the corresponding track segment for cleaning. Whether through the cleaning brush assembly 500 or the frosting and defrosting process of the indoor heat exchanger 200, cleaning efficiency is improved. The intelligent cleaning system ensures that the filter always maintains optimal working condition, effectively improving indoor air quality.

[0105] Furthermore, a second aspect of this application also provides a control method for an air conditioner indoor unit, applied to the air conditioner indoor unit provided in the first aspect of this application. The control method includes:

[0106] Obtain the dirt and clogging parameter value that characterizes the dirt and clogging of the filter, control the filter to move to different track segments of the filter track according to the magnitude of the dirt and clogging parameter value, and control the operation of the indoor unit of the air conditioner according to the track segment corresponding to the filter.

[0107] The operation status of the indoor unit of the air conditioner includes at least the opening and closing status of the cleaning components and the operating mode of the indoor unit.

[0108] The operating modes include cooling mode and heating mode.

[0109] In other words, the indoor unit of the air conditioner in this embodiment can intelligently determine when cleaning is needed, making the cleaning process more automated and intelligent. Specifically, based on the parameter values ​​output by the sensors, the controller can precisely control the filter to move to the corresponding track segment for cleaning. Whether through the cleaning brush assembly 500 or through the frosting and defrosting process of the indoor heat exchanger 200, cleaning efficiency can be improved. The intelligent cleaning system ensures that the filter always maintains optimal working condition, effectively improving indoor air quality.

[0110] Furthermore, in some possible implementations, the movement of the filter screen to different track segments is controlled according to the magnitude of the dirt / clogging parameter value, and the operation of the indoor air conditioning unit is controlled according to the track segment corresponding to the filter screen, including:

[0111] If the dirt clogging parameter value is greater than the first preset dirt clogging parameter value and less than the second preset dirt clogging parameter value, the filter screen is controlled to move into the track transition section, and the cleaning component is controlled to clean the surface of the filter screen placed in the track transition section.

[0112] If the dirt clogging parameter value is greater than or equal to the second preset dirt clogging parameter value, the filter screen is moved to the indoor heat exchanger section of the track, and the indoor unit of the air conditioner is controlled to run the self-cleaning mode to make the surface of the indoor heat exchanger frost and then defrost, so as to wash and clean the filter screen attached to the surface of the indoor heat exchanger.

[0113] In this embodiment, by setting preset dirt clogging parameter values, the control method can adopt different cleaning measures according to the actual dirt clogging condition of the filter screen, realizing a graded cleaning strategy. Specifically, when the dirt clogging parameter value is greater than a first preset dirt clogging parameter value but less than a second preset dirt clogging parameter value, the filter screen is moved to the track transition section for cleaning; when the dirt clogging parameter value is greater than or equal to the second preset dirt clogging parameter value, the filter screen is moved to the heat exchanger section inside the track for more thorough water washing. This response mechanism improves the efficiency and timeliness of cleaning. That is, for filter screens that are not too dirty, only the cleaning component is used for cleaning, avoiding unnecessary energy waste. For filter screens that are relatively dirty, a self-cleaning mode is adopted. Although energy consumption is relatively increased, the cleaning is more thorough, and overall, energy use is optimized.

[0114] That is, the indoor unit of the air conditioner in this embodiment can take different cleaning measures according to different dirt and blockage conditions to ensure that the filter is always in good working condition and effectively improve indoor air quality.

[0115] Furthermore, in some possible implementations, controlling the indoor unit of the air conditioner to operate in a self-cleaning mode to cause frost to form and then defrost the surface of the indoor heat exchanger includes:

[0116] The system controls the indoor unit of the air conditioner to run in cooling mode and heating mode respectively. The cooling mode causes frost to form on the surface of the indoor heat exchanger, while the heating mode controls the defrosting of the indoor heat exchanger surface.

[0117] In this embodiment, the indoor unit of the air conditioner is automatically controlled to switch between cooling and heating modes, achieving automated frosting and defrosting of the indoor heat exchanger surface without manual intervention, thus improving the convenience of the self-cleaning process. The frost generated in cooling mode and the heat generated in heating mode are used to wash the filter screen; this physical cleaning method can more effectively remove stubborn dirt and bacteria from the filter screen, improving the cleaning effect. By precisely controlling the operating time and conditions of cooling and heating modes, energy consumption can be optimized, and self-cleaning can be performed only when necessary, avoiding unnecessary energy waste.

[0118] Furthermore, in some possible implementations, the method for controlling the operation of the indoor unit of the air conditioner in heating mode includes:

[0119] The temperature of the indoor heat exchanger is raised to a first preset temperature value and continues to operate at the first preset temperature value for a first preset duration.

[0120] The first preset temperature value is between 50-55℃, and the first preset duration value is between 10min-15min.

[0121] In this embodiment, by setting a specific first preset temperature value (50-55℃) and a first preset duration (10-15 minutes), the temperature and time of the indoor heat exchanger during the self-cleaning process can be precisely controlled to ensure the cleaning effect. Running at a temperature of 50-55℃ for 10-15 minutes can effectively melt the frost layer on the surface of the indoor heat exchanger and effectively dry the filter screen 400.

[0122] To better understand the control principle of the indoor unit of the air conditioner in the embodiments of this application, the following is combined with... Figures 1-7 Please provide a detailed explanation:

[0123] The air conditioning indoor unit provided in this embodiment includes a flexible filter 400, a filter track 300, a first roller 701, a second roller 702, a moving brush 501, a fixed brush 502, a dust collection assembly 600 with a dust collection box, and a dirt clogging sensor 800. The filter track 300 consists of three track sections: a track air inlet section 301, a track transition section 302, and a track indoor heat exchanger section 303, as shown below. Figures 1-3As shown, the first roller 701 is installed between the track air inlet section 301 and the track transition section 302, and the second roller 702 is installed between the track transition section 302 and the track indoor heat exchanger section 303. The rollers {first roller 701 and second roller 702} are driven to rotate by a motor. Gears are installed on both sides of the rollers, which can mesh with the rack belts on both sides of the flexible filter screen 400, thereby driving the flexible filter screen 400 to move on the filter screen track 300. A movable brush is installed on the other side of the first roller 701 opposite to the track. The indoor air conditioning unit also includes an aluminum connecting rod 5011 and a brush holder 5012. The movable brush 501 is attached to the connecting rod 5011 via the holder 5012 and can be driven by a motor to perform circular motion. The fixed brush 502 is attached to the cavity wall of the unit body 100. The dust collection box is located below the movable brush 501 and the fixed brush 502. The dirt clogging sensor 800 can detect the degree of dirt clogging A1 of the filter screen 400 and determine the dust removal mode based on the degree of dirt clogging: primary dust removal (A1 < A) and final dust removal (A1 ≥ A).

[0124] Basic dust removal mode:

[0125] like Figure 1 The image shows the dust removal structure in its reset state, with the flexible filter 400 located at the air inlet section 301 of the air conditioner filter track. The air conditioner begins dust removal; the dirt clogging sensor detects this. If A1 < A, the air conditioner activates the primary dust removal mode. Figure 2 As shown, the flexible filter screen is driven by the first roller 701 and enters the track transition section 302. The moving brush 501 is tangent to the flexible filter screen 400. At this time, the filter screen 400 rotates downwards, while the moving brush 501 remains stationary in the cleaning position. During the operation of the filter screen 400, dust is swept away. Some of the swept dust falls into the dust collection box, while some remains suspended on the moving brush 501. To prevent the rack and pinion belt of the flexible filter screen 400 from disengaging from the gears of the first roller 701, the operation time t1 of the filter screen should be equal to L1 / V, where L1 is the distance of the air inlet section 301 of the filter screen track, and V is the speed of the filter screen 400's uniform motion. After the filter screen 400 stops, the first roller 701 rotates in the opposite direction, and the flexible filter screen 400 returns to its initial position. At this time, the moving brush 501 rotates one revolution, achieving self-cleaning of the moving brush 501 through contact with the stationary brush 502.

[0126] Ultimate Dust Removal Mode:

[0127] If the dirt and clogging sensor detects a blockage and A1 ≥ A, the air conditioner will activate its ultimate dust removal mode. Figure 3As shown, the flexible filter screen is driven by the first roller 701 and the second roller 702 to enter the filter screen track indoor heat exchanger section 303. The first roller 701 and the second roller 702 rotate at the same speed. When the filter screen 400 passes through the track transition section 302, the moving brush 501 cleans the filter screen 400. Similarly, the subsequent fixed brush 502 also cleans the moving brush 501. The filter screen running time t2 is (L2+L3) / V, where L2 is the distance of the filter screen track transition section 302, L3 is the distance of the filter screen track indoor heat exchanger section 303, and V is the uniform speed of the filter screen 400. When the filter screen 400 moves to the track indoor heat exchanger section 303, the flexible filter screen 400 comes into contact with the surface of the first inclined heat exchange section 201 at the front end of the indoor heat exchanger 200. Combined with the self-cleaning function of the indoor heat exchanger 200, the filter screen 400 is cleaned. Specifically, the process involves utilizing the condensation effect of the air conditioner's cooling mode to cause condensate to adhere to the indoor heat exchanger 200 and the flexible filter 400. The condensate combines with dust, and then the temperature of the indoor heat exchanger 200 is rapidly reduced, causing the condensate to quickly frost over. The system then switches to heating mode, rapidly melting the frost and washing away the dust and water. Finally, the temperature of the indoor heat exchanger 200 rises to 50-55°C and remains there for 10-15 minutes, drying the filter. After dust removal, the first roller 7011 and the second roller 702 rotate in opposite directions, and the flexible filter 400 returns to its initial position.

[0128] Throughout the cleaning process, dust and other foreign objects swept up by the cleaning brush assembly 500 fall into the dust collection box of the dust collection assembly 600. After dust removal is completed, the indoor unit checks whether the weight of the dust collection box has reached the preset value. If it does, it issues a reminder, and the user removes and cleans the dust collection box.
