[0067] Background

[0068] With the improvement of people's living standards, air conditioners are prevalent in daily life, which leads to higher and higher requirements for the overall performance of air conditioners, especially for the cleaning and dust removal functions of air conditioners.

[0069] After long-term use of the air conditioner, dust will gradually accumulate on the indoor unit filter of the air conditioner, which is easy to breed bacteria and cause the indoor air quality to deteriorate. In the prior art, the air conditioner is cleaned manually, which requires the various parts of the air conditioner to be disassembled for cleaning, and after cleaning, the various parts need to be reassembled, which is time-consuming and laborious.

[0070] Some air conditioners also have an automatic brush to clean the filter, but it is difficult to clean the wet and sticky dust on the filter in humid air.

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

[0072] The body 100 has an air inlet 101 at the top thereof;

[0073] An indoor heat exchanger 200 is disposed inside the machine body 100, and an installation space is defined between the indoor heat exchanger 200 and the machine 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, wherein the track air inlet section 301 is arranged corresponding to the air inlet 101 and is arranged above the indoor heat exchanger 200 and is spaced apart from the indoor heat exchanger, the track indoor heat exchanger section 303 is arranged on the surface of the indoor heat exchanger 200 and the filter 400 is configured as follows: when the filter is moved into the track indoor heat exchanger section 303, cleaning can be achieved by frosting and then defrosting the indoor heat exchanger 200.

[0075] In the embodiment of the present application, the filter track 300 is divided into a track air inlet section 301 and a track indoor heat exchanger section 303, wherein the track indoor heat exchanger section 303 is in contact with the surface of the indoor heat exchanger 200. This design enables 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 in contact with the surface of the indoor heat exchanger 200 can be washed and cleaned. This self-cleaning mechanism utilizes the cooling and heating functions of the air conditioner itself, without the need for additional cleaning equipment or manual intervention, reducing maintenance costs and user operation complexity. At the same time, since the filter 400 can be more effectively in contact with the surface of the indoor heat exchanger and washed and cleaned, the dust and bacteria on the filter 400 can be removed more thoroughly, thereby improving the cleanliness of the indoor air and providing users with a healthier living environment.

[0076] Further, in some possible implementations, the track indoor heat exchanger section is close to the surface of the indoor heat exchanger 200;

[0077] When the filter net 400 moves to the track indoor heat exchanger section 303, the filter net 400 frosts synchronously when the indoor heat exchanger 200 frosts, and the filter net 400 defrosts synchronously when the indoor heat exchanger 200 defrosts.

[0078] In this way, when the indoor heat exchanger 200 is frosted and then defrosted, the filter 400 moved to the track indoor heat exchanger section 303 can also be frosted and then defrosted synchronously, so that the surface of the filter 400 can be washed and cleaned with defrosting water after frosting and then defrosting.

[0079] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the indoor heat exchanger 200 includes a top end of the indoor heat exchanger close to the air inlet 101, a first inclined heat exchange section 201 extending obliquely downward from the top end of the indoor heat exchanger to the front side of the body 100, and a second inclined heat exchange section 202 extending obliquely downward from the top end of the indoor heat exchanger to the rear side of the body 100;

[0080] The track indoor heat exchanger section 303 is arranged in close contact with the first inclined heat exchange section 201 and / or in close contact with the second inclined heat exchange section 202 .

[0081] Since the filter net 400 can be fitted with the inclined first inclined heat exchange section 201 and / or the second inclined heat exchange section 201, the contact area between the filter net 400 and the surface of the indoor heat exchanger 200 is increased, so that when the filter net 400 is washed and cleaned by controlling the frosting and defrosting process of the indoor heat exchanger 200, the cleaning effect is better. At the same time, since the filter net 400 can be fitted with the inclined first inclined heat exchange section 201 and / or the second inclined heat exchange section 201, when the indoor heat exchanger 200 washes and cleans the filter net 400 by frosting and defrosting, it is easier to drain the cleaning water after cleaning, thereby avoiding the cleaning water remaining on the surface of the indoor heat exchanger 200.

[0082] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the filter track 300 also includes a track transition section 302 connected between the track air inlet section 301 and the track indoor heat exchanger section 303, and the track transition section 302 is arranged to avoid the air inlet 101;

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

[0084] In the embodiment of the present application, a track transition section 302 is added between the track air inlet end 301 and the track indoor heat exchanger section 303, so that the filter 400 will pass through a transition area when moving from the air inlet track section 301 to the indoor heat exchanger track section 303. In this transition area, the cleaning brush assembly 500 can clean the filter to ensure that the accumulation of dust and dirt on the filter 400 is reduced as much as possible before reaching the surface of the indoor heat exchanger 200. At the same time, since the design of the track transition section 302 avoids the air inlet 101, this means that in the process of cleaning the filter, the dust that falls after cleaning will not be blown onto other parts in the body 100 due to the inlet airflow of the air inlet 101, thereby improving the dust collection effect.

[0085] Furthermore, in some possible embodiments, the track air inlet section 301 extends along the front-to-back 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 to 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 obliquely upward.

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

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

[0088] The track indoor heat exchanger section 303 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] That is, the track transition section 302 in the embodiment of the present application is arranged at the front side of the machine body 100, which has the advantage that it is more convenient for the personnel to disassemble and maintain the filter assembly later, and it is also convenient for the personnel to clean the dust collection assembly later. Figure 1-Figure 3 As shown, the dust collection assembly in the embodiment of the present application includes a dust box detachably connected to the front side of the body 100. In the embodiment of the present application, the track transition section 302 and the dust box are arranged on the front side of the body 100, so that when the dust in the dust box accumulates to a certain extent, the user or maintenance personnel can more easily remove the dust box from the body 100.

[0090] Further, in some possible implementations, such as Figure 1-Figure 3As shown, the cleaning brush assembly 500 includes a dynamic brush 501 rotatably disposed between the track transition section 302 and the body 100. The dynamic brush 501 has a first position and a second position when rotating. When the dynamic brush 501 is in the first position, the filter screen 400 moved to the track transition section 302 can be cleaned;

[0091] The cleaning brush assembly 500 further includes a fixed brush 502 whose position is fixed. When the dynamic brush 501 is in the second position, it can contact the fixed brush 502 so that the dynamic brush 501 can be cleaned by the fixed brush 502 .

[0092] In the embodiment of the present application, by setting a moving brush 501 and a fixed brush 502, a double-brush cleaning mechanism is realized for the indoor unit of the air conditioner. The moving brush 501 cleans the filter 400 when in the first position, and contacts the fixed brush 502 when in the second position, and the moving brush 501 is cleaned by the fixed brush 502. This design improves the cleaning efficiency and effect. The rotating setting of the moving brush 501 automates the cleaning process of the filter in the track transition section 302, reduces manual intervention, and improves the convenience and efficiency of cleaning. The moving brush 501 can be self-cleaned by the fixed brush 502 when in the second position, which means that the cleaning component can achieve self-maintenance without adding additional complex mechanical structures, reducing maintenance costs and workload.

[0093] Further, in some possible implementations, the air conditioner indoor unit further includes:

[0094] The dust collecting assembly 600 includes a dust collecting box which is arranged at the bottom of the cleaning brush assembly 500 and has an opening at the top. The dust collecting box is used to collect dust after cleaning by the cleaning brush assembly 500.

[0095] In the embodiment of the present application, by providing a dust collection assembly 600, in particular a dust collection box, the dust generated by the cleaning brush assembly 500 when cleaning the filter 400 can be effectively collected. This helps prevent dust from escaping into the air during the cleaning process and keeps the indoor air clean. It is worth noting that the dust collection box is detachably connected to the body 100, which makes it easy for subsequent users or maintenance personnel to disassemble and install the dust collection box.

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

[0097] A driving assembly 700, the driving assembly 700 includes a first roller 701 and a second roller 702 that can be driven to rotate;

[0098] The first roller 701 is arranged at the connection position between the track air inlet section 301 and the track transition section 302 , and the second roller 702 is arranged at the connection position between the track transition section 302 and the track indoor heat exchanger section 303 .

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

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

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

[0102] The sensor 800 is used to detect and output a parameter value representing the dirtiness and blockage of the filter 400;

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

[0104] In the embodiment of the present application, the filter 400 is detected by the sensor 800 to detect the dirtiness and blockage of the filter, and the indoor unit of the air conditioner can intelligently determine when cleaning is needed, making the cleaning process more automated and intelligent. Specifically, the controller can accurately control the filter to move to the corresponding track section for cleaning according to the parameter value output by the sensor. Whether it is through the cleaning brush assembly 500 or through the frosting and defrosting process of the indoor heat exchanger 200, the cleaning efficiency can be improved. The intelligent cleaning system ensures that the filter always maintains a good working condition, effectively improving the indoor air quality.

[0105] Furthermore, the second aspect of the embodiment of the present application further provides a control method for an air conditioner indoor unit, which is applied to the air conditioner indoor unit provided in the first aspect of the embodiment of the present application, and the control method includes:

[0106] Obtain a dirty and blocked parameter value representing the dirty and blocked condition of the filter, control the filter to move to different track segments of the filter track according to the size of the dirty and blocked parameter value, and control the operation of the air conditioner indoor unit according to the track segment corresponding to the filter;

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

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

[0109] That is, the indoor unit of the air conditioner in the embodiment of the present application can intelligently determine when cleaning is needed, making the cleaning process more automated and intelligent. Specifically, the controller can accurately control the filter to move to the corresponding track section for cleaning according to the parameter value output by the sensor. Whether through the cleaning brush assembly 500 or through the frosting and defrosting process of the indoor heat exchanger 200, the cleaning efficiency can be improved. The intelligent cleaning system ensures that the filter always maintains a good working state, effectively improving the indoor air quality.

[0110] Further, in some possible implementations, the filter is controlled to move to different track segments of the filter track according to the size of the dirty and blocked parameter value, and the operation of the air conditioner indoor unit is controlled according to the track segment corresponding to the filter, including:

[0111] If the dirty and clogging parameter value is greater than the first preset dirty and clogging parameter value and less than the second preset dirty and 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 dirty and blocked parameter value is greater than or equal to the second preset dirty and blocked parameter value, the filter is controlled to move to the track indoor heat exchanger section, and the air-conditioning indoor unit is controlled to run the self-cleaning mode to frost and defrost the surface of the indoor heat exchanger, so that the filter attached to the surface of the indoor heat exchanger can be washed and cleaned with water.

[0113] In the embodiment of the present application, by setting a preset dirty and blocked parameter value, the control method can take different cleaning measures according to the actual dirty and blocked conditions of the filter, and implement a graded cleaning strategy. Specifically, when the dirty and blocked parameter value is greater than the first preset dirty and blocked parameter value and less than the second preset dirty and blocked parameter value, the filter is moved to the track transition section for cleaning; when the dirty and blocked parameter value is greater than or equal to the second preset dirty and blocked parameter value, the filter is moved to the track indoor heat exchanger section for more in-depth water washing and cleaning. This response mechanism improves the efficiency and timeliness of cleaning. That is, for filters that are not too dirty, only the cleaning components are used for cleaning, avoiding unnecessary energy waste. For dirty filters, a self-cleaning mode is adopted. Although the energy consumption is relatively increased, the cleaning is more thorough, and the overall optimized use of energy is achieved.

[0114] That is, the air-conditioning indoor unit in the embodiment of the present application can take different cleaning measures according to different dirt and blockage conditions, ensuring that the filter is always in a good working condition and effectively improving the indoor air quality.

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

[0116] The air conditioner indoor unit is controlled to run the cooling mode and the heating mode respectively. The surface of the indoor heat exchanger is frosted by the operation of the cooling mode, and the surface of the indoor heat exchanger is defrosted by the operation of the heating mode.

[0117] In the embodiment of the present application, the indoor unit of the air conditioner is automatically controlled to switch between the cooling mode and the heating mode, thereby realizing the automatic frosting and defrosting of the indoor heat exchanger surface without manual intervention, thereby improving the convenience of the self-cleaning process. The filter is washed with water using the frost generated by the cooling mode and the heat generated by the heating mode. This physical cleaning method can more effectively remove stubborn dirt and bacteria on the filter and improve the cleaning effect. By precisely controlling the operating time and conditions of the cooling and heating modes, energy consumption can be optimized, and self-cleaning can be performed only when necessary to avoid unnecessary energy waste.

[0118] Further, in some possible implementations, the method for controlling the air conditioner indoor unit to operate in a heating mode includes:

[0119] Controlling the temperature of the indoor heat exchanger to rise to a first preset temperature value, and continuously operating at the first preset temperature value for a first preset time period;

[0120] The first preset temperature value is between 50-55°C, and the first preset time value range is between 10min-15min.

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

[0122] In order to more clearly understand the control principle of the air conditioner indoor unit in the embodiment of the present application, Figure 1-Figure 7 To explain in detail:

[0123] The air conditioner indoor unit provided in the embodiment of the present application 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 collecting assembly 600 with a dust collecting box, and a dirt blockage sensor 800. The filter track 300 is composed of three sections, namely, a track air inlet section 301, a track transition section 302, and a track indoor heat exchanger section 303, as shown in FIG. Figure 1-Figure 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 {the first roller 701 and the second roller 702} are driven by a motor to rotate. Gears are installed on both sides of the rollers, which can mesh with the rack belts on both sides of the flexible filter 400, thereby driving the flexible filter 400 to move on the filter track 300. The moving brush is installed on the other side of the first roller 701 relative to the track. The air conditioner indoor unit also includes an aluminum connecting rod 5011 and a brush bracket 5012. The moving brush 501 is adhered to the connecting rod 5011 through the bracket 5012 and can be driven by the motor to perform circular motion. The fixed brush 502 is adhered to the cavity wall of the body 100. The dust box is located below the moving brush 501 and the fixed brush 502. The dirtiness and clogging sensor 800 can detect the dirtiness and clogging degree A1 of the filter 400, and determine the dust removal mode according to the dirtiness and clogging degree, namely, primary dust removal (A1<A) and ultimate dust removal (A1≥A).

[0124] Primary dust removal mode:

[0125] like Figure 1 The dust removal structure is shown in the reset state, and the flexible filter 400 is located at the air inlet section 301 of the air conditioner filter track. The air conditioner starts to remove dust, and the dirty blockage sensor detects that if A1 < A, the air conditioner starts the primary dust removal mode, such as Figure 2 As shown, the flexible filter is driven by the first roller 701 and enters the track transition section 302. The position of the moving brush 501 is tangent to the flexible filter 400. At this time, the filter 400 runs downward, and the moving brush 501 is in the cleaning position and does not move. During the operation of the filter 400, dust is cleaned. Part of the cleaned dust falls into the dust box, and part is suspended on the moving brush 501. In order to prevent the rack belt of the flexible filter 400 from being de-toothed from the gear of the first roller 701, the time t1 of the filter operation should be equal to L1 / V, where L1 is the distance of the filter track air inlet section 301, and V is the speed of the uniform motion of the filter 400. After the filter 400 stops running, the first roller 701 rotates in the opposite direction, and the flexible filter 400 returns to the initial position. At this time, the moving brush 501 rotates one circle, and the self-cleaning of the moving brush 501 is achieved through contact with the fixed brush 502.

[0126] Ultimate Dust Removal Mode:

[0127] Dirt blockage sensor detection, if A1≥A, the air conditioner turns on the ultimate dust removal mode, such as Figure 3As shown, the flexible filter is driven by the first roller 701 and the second roller 702 to enter the indoor heat exchanger section 303 of the filter track. The first roller 701 and the second roller 702 rotate at the same speed. When the filter 400 passes through the track transition section 302, the moving brush 501 removes dust and cleans the filter 400. Similarly, the subsequent fixed brush 502 will also clean the moving brush 501. The filter operation time t2 is (L2+L3) / V, L2 is the distance of the filter track transition section 302, L3 is the distance of the filter track indoor heat exchanger section 303, and V is the uniform speed of the filter 400. When the filter 400 moves to the track indoor heat exchanger section 303, the flexible filter 400 is attached to the surface of the first inclined heat exchange section 201 at the front end of the indoor heat exchanger 200, and the filter 400 is cleaned in combination with the self-cleaning function of the indoor heat exchanger 200. Specifically, the condensation in the air conditioning cooling mode is used to make the condensed water adhere to the indoor heat exchanger 200 and the flexible filter 400, and the condensed water combines with the dust, and then the temperature of the indoor heat exchanger 200 is quickly reduced to make the condensed water quickly frost, and then the heating mode is switched to make the frost layer melt quickly, and the dust is washed away together with the water, and finally, the temperature of the indoor heat exchanger 200 is increased to 50-55°C and maintained for 10-15 minutes to dry the filter. After the dust removal is completed, the first drum 7011 and the second drum 702 rotate in the opposite direction, and the flexible filter 400 returns to the initial position.

[0128] During the entire cleaning process, dust and other foreign matter swept by the cleaning brush assembly 500 falls into the dust box of the dust collection assembly 600. After dust removal, the indoor unit determines whether the weight of the dust box reaches a preset value. If the preset value is reached, a reminder is issued to the user to disassemble and clean the dust box.
