Description

Technical Field

[0001] This utility model relates to the field of air supply equipment technology, and in particular to a wall-mounted air conditioner indoor unit. Background Technology

[0002] Existing wall-mounted air conditioners typically have a filter and a baffle at the air inlet. The filter is used to filter dust in the incoming airflow when the air conditioner is turned on, and the baffle is used to close the air inlet when the air conditioner is turned off. However, after long-term use, dust will accumulate on the filter and baffle, which will affect the normal operation of the air conditioner. Therefore, it is necessary to clean the filter and baffle.

[0003] However, existing wall-mounted air conditioners typically only remove dust from the filter screen, not the baffle. Furthermore, existing air conditioners generally employ two methods for filter dust removal: one involves the filter circulating within a multi-layer track, but this method is complex and costly. The other method uses a single-layer track with a roller winding system. However, this method results in an overly thick unit due to the large diameter of the roller, leading to a poor appearance. Utility Model Content

[0004] To overcome the limitations of existing air conditioners that cannot effectively remove dust from baffles, and the high cost and large size of air conditioners when using dust removal structures to clean filters, this invention proposes a control method for a wall-mounted air conditioner indoor unit. By setting a first track for baffle movement and a second track for filter movement within the indoor unit, combined with a cleaning mechanism, the baffle can be moved along the first track for cleaning, and the filter can be moved along the second track for cleaning. This achieves cleaning of both the baffle and the filter. Furthermore, by placing the first side section of the first track and the second side section of the second track between the heat exchanger and the front of the unit, the space between the heat exchanger and the front of the unit is fully utilized to move the baffle and filter, thus achieving self-cleaning of the baffle and filter without increasing the thickness of the air conditioner.

Detailed Implementation

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0065] Currently available wall-mounted air conditioners cannot perform dust removal on the air inlet baffle. Furthermore, using a dust removal structure to clean the filter at the air inlet results in high cost and large size for the air conditioner. This invention proposes a control method for a wall-mounted air conditioner indoor unit. By setting a first track for baffle movement and a second track for filter movement within the indoor unit, combined with a cleaning mechanism, the baffle can be moved along the first track for cleaning by the cleaning mechanism when needed. Conversely, the filter can be moved along the second track for cleaning by the cleaning mechanism when needed. This achieves cleaning of both the baffle and the filter. Furthermore, by placing the first side section of the first track and the second side section of the second track between the heat exchanger and the front of the unit, this invention fully utilizes the space between the heat exchanger and the front of the unit to move the baffle and filter, thus achieving self-cleaning of the baffle and filter without increasing the thickness of the air conditioner.

[0066] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0067] Example

[0068] like Figures 1-3 As shown, the first aspect of this utility model provides a wall-mounted air conditioner indoor unit, comprising:

[0069] The housing 1 has an air inlet 11 formed on its top.

[0070] Heat exchanger 2 is located inside the casing 1. A top space 3 is defined between the top of the heat exchanger 2 and the air inlet 11 at the top of the casing 1, and a front space 4 is defined between the front of the heat exchanger 2 and the front of the casing 1.

[0071] The first track 5 and the second track 6 are independent of each other. Both the first track 5 and the second track 6 are located inside the housing 1. The first track 5 includes a first track top section 51 located in the top space 3 and a first track side section 52 that communicates with the first track top section 51 and is located in the front space 4. The second track 6 includes a second track top section 61 located in the top space 3 and a second track side section 62 that communicates with the second track top section 61 and is located in the front space 4.

[0072] Baffle 7 and filter screen 8 are provided. Baffle 7 is movably disposed in the first track 5, and when the baffle 7 moves, it has a first top position located at the top section 51 of the first track and a first side position located at the side section 52 of the first track. Filter screen 8 is movably disposed in the second track 6, and when the filter screen 8 moves, it has a second top position located at the top section 61 of the second track and a second side position located at the side section 62 of the second track.

[0073] A cleaning mechanism is located inside the housing 1 and is used to clean the baffle 7 when it moves and / or to clean the filter screen 8 when it moves.

[0074] In this embodiment of the invention, a first track 5 for moving the baffle 7 and a second track 6 for moving the filter 8 are provided in the casing 1 of the indoor unit. Combined with a cleaning mechanism, when the baffle 7 and filter 8 require cleaning, the cleaning mechanism can clean the moving baffle 7 and filter 8, thus eliminating the need for frequent cleaning of the filter and baffle by the user. Simultaneously, the independent operation of the baffle 7 and filter 8 on their respective tracks allows for simultaneous and individual cleaning of the filter 8 and baffle 7, improving the reliability of dust removal operation. Furthermore, the first track 5 and the second track 6 are positioned between the heat exchanger 2 and the front panel of the casing 1, fully utilizing the space between them and avoiding excessive thickness of the indoor unit in the front-to-back direction due to the track arrangement.

[0075] It is worth noting that, after installation, the top of the wall-mounted air conditioner indoor unit provided in this embodiment of the present invention faces the ceiling, the bottom of the casing faces the base plate, the front of the casing faces the user, and the rear of the casing faces the wall, which is also the side that matches the wall.

[0076] Specifically, such as Figures 1-3 As shown, the top section 51 of the first track is positioned closer to the top of the housing 1 than the top section 61 of the second track.

[0077] The first track side section 52 is positioned closer to the front of the housing 1 than the second track side section 62.

[0078] In this embodiment of the present invention, the first track 5 is positioned closer to the outer side of the casing than the second track 6. When the air conditioner is off, the air inlet can be closed by the baffle 7 on the outer side. This not only prevents the inner filter from getting dusty, but also ensures that the baffle 7 fits perfectly with the outer surface of the casing, thus guaranteeing the consistency of the indoor unit's appearance.

[0079] In any of the above embodiments, such as Figures 1-3 As shown, the cleaning mechanism includes a first brush assembly and a second brush assembly;

[0080] The first brush assembly is used to clean the surface of the baffle 7 when the baffle 7 moves in the first track 5, and the second brush assembly is used to clean the surface of the filter screen 8 when the filter screen 8 moves in the second track 6.

[0081] Specifically, the baffle 7 has an outer baffle surface facing the outside of the housing 1 and an inner baffle surface opposite to the outer baffle surface;

[0082] The filter screen 8 has an outer filter screen surface facing the outside of the housing 1 and an inner filter screen surface opposite to the outer filter screen surface;

[0083] The first brush assembly is used to clean the outer baffle surface of the baffle 7 when the baffle 7 moves in the first track 5, and the second brush assembly is used to clean the outer filter surface of the filter screen 8 when the filter screen 8 moves in the second track 6.

[0084] Since the outer baffle surface of the baffle 7 and the outer filter screen surface of the filter screen 8 both face the outside of the housing 1, cleaning the outer baffle surface and the outer filter screen surface by the first brush assembly and the second brush assembly can effectively clean most of the dust on the baffle 7 and the filter screen 8, thereby improving the cleaning effect of the baffle 7 and the filter screen 8 per unit time.

[0085] In any of the above embodiments, such as Figure 2 and Figure 3 As shown, the first brush assembly includes a first fixed brush 100, a first movable brush 200, and a first brush motor that drives the first movable brush to rotate. When driven to rotate, the first movable brush 200 has a first cleaning position A and a first cleaning position B. When the first movable brush 200 is in the first cleaning position A, it can contact the surface of the baffle 7 to clean the surface of the baffle 7. When the first movable brush 200 is in the first cleaning position B, it can contact the first fixed brush 100 to clean the first movable brush 200; and / or

[0086] The second brush assembly includes a second fixed brush 300, a second movable brush 400, and a second brush motor that drives the second movable brush 400 to rotate. When the second movable brush 400 is driven to rotate, it has a second cleaning position A and a second cleaning position B. When the second movable brush 400 is in the second cleaning position A, it can contact the surface of the filter screen 8 to clean the surface of the filter screen 8. When the second movable brush 400 is in the second cleaning position B, it can contact the second fixed brush 300 to clean the second movable brush 400.

[0087] In this embodiment of the utility model, the indoor unit of the air conditioner can clean the surface of the moving baffle 7 and the filter screen 8 by setting a first moving brush 200 and a second moving brush 400, and can clean the first moving brush 200 and the second moving brush 400 by setting a first fixed brush 100 and a second fixed brush 300, thereby achieving the self-cleaning effect of the first moving brush 200 and the second moving brush 400.

[0088] In any of the above embodiments, such as Figure 2 and Figure 3 As shown, the indoor unit of the air conditioner also includes:

[0089] The driving device includes a first driving device 500 for driving the baffle 7 to move in the first track 5, and a second driving device 600 for driving the filter screen 8 to move in the second track 6.

[0090] The first driving device 500 includes a first roller rotatably disposed between the top section 51 and the side section 52 of the first track, wherein the first roller and the baffle 7 are driven by gear meshing; and / or

[0091] The second drive unit 600 includes a second roller rotatably disposed between the top section 61 and the side section 62 of the second track, and the second roller and the filter screen 8 are driven by gear meshing.

[0092] In this embodiment of the present invention, the first driving device 500 is located in the middle of the first track 5, and the second driving device 600 is located in the middle of the second track 6, thereby facilitating the installation of the first driving device 500 and the second driving device 600.

[0093] Furthermore, the length of the baffle 7 is designed such that, when the baffle 7 is in the first top position or the first side position, at least a portion of the baffle 7 engages with the first roller via gears; and / or

[0094] The length of the filter screen 8 is designed such that when the filter screen 8 is in the second top position or the second side position, at least a portion of the filter screen 8 engages with the second roller via gears.

[0095] In this embodiment of the invention, by designing the length of the filter screen, it can be ensured that the filter screen 8 and the baffle 7 will never come off during operation.

[0096] Specifically, when the air conditioner is turned on, such as Figure 1 As shown, the second motor drives the second roller to rotate clockwise, moving the filter screen 8 from the side away from the air inlet 11 (i.e., the side section 62 of the second track) to the side of the air inlet 11 (i.e., the top section 61 of the second track); the first motor drives the first roller to rotate counterclockwise, moving the baffle 7 from the side of the air inlet 11 (i.e., the top section 51 of the first track) to the side away from the air inlet 11 (i.e., the side section 52 of the first track). The filter screen 8 and the baffle 7 stop moving after reaching the top of the other side. It is set that the filter screen 8 and the baffle 7 move at a constant speed in their corresponding tracks. Preferably, the top section 51 of the first track and the top section 61 of the second track have the same length, and the side section 52 of the first track and the side section 62 of the second track have the same length. Therefore, the movement time t of the baffle 7 and the filter screen 8 should satisfy t = (Ld) / a.

[0097] When the above formula is used to calculate the movement time of baffle 7, t in the above formula is specifically t1, L is specifically L1, d is specifically d1, and a is specifically a1.

[0098] When the above formula is used to calculate the movement time of filter screen 8, t in the above formula is specifically t2, L is specifically L2, d is specifically d2, and a is specifically a2.

[0099] Where L1 is the length of the first track 5, d1 is the length of the baffle 7, a1 is the rotational speed of the first roller, L2 is the second track 6, d2 is the length of the filter screen 8, and a2 is the rotational speed of the second roller. To ensure that the filter screen 8 and the baffle 7 do not disengage during operation, the first roller is set to be located in the middle position of the first track 4, and the second roller is set to be located in the middle position of the second track 6, with d1 > L1 / 2 and d2 > L2 / 2.

[0100] In any of the above embodiments, the indoor unit of the air conditioner further includes:

[0101] Dust collection box 9, located in the front space 4, is used to collect dust that falls off the cleaning mechanism when cleaning the baffle 7 and / or filter screen 8;

[0102] The dust collection box 9 is detachably embedded in the front space 4.

[0103] In this embodiment of the utility model, the dust collection box 9 is detachably arranged in the front space 4 at the front of the housing 1, which facilitates the user to remove the dust collection box 9.

[0104] Specifically, such as Figure 2 and Figure 3As shown, the dust collection box 9 includes a first dust collection box 91 and a second dust collection box 92;

[0105] The first dust collection box 91 is located below the first brush assembly and is used to collect dust that falls off the first brush assembly when cleaning the baffle 7 and / or during self-cleaning.

[0106] The second dust collection box 92 is located below the second brush assembly and is used to collect dust that falls off the second brush assembly when cleaning the filter 8 and / or during self-cleaning.

[0107] In any of the above embodiments, the front of the housing 1 is provided with an air outlet 12;

[0108] The top of the dust collection box 9 has an opening, and the side of the dust collection box 9 has an air vent. A filter device is provided at the air vent. When the dust collection box 9 is embedded in the front space 4, the top opening of the dust collection box 9 is used to collect dust, and the side air vent of the dust collection box 9 opens to the front of the housing 1 and is located above the air outlet 12 at the front of the housing 1.

[0109] When the air outlet 12 emits air, it can create a negative pressure at the air vent of the dust collection box 9, so as to draw the dust in the front space 4 into the dust collection box 9 through the negative pressure.

[0110] In this embodiment of the utility model, the dust collection box 9 is placed above the air outlet 12 and adjacent to the air outlet 12 {preferably, the distance between the air vent on the dust collection box 9 and the air outlet 12 is maintained between 1cm and 10cm, which can be considered as the dust collection box 9 being adjacent to the air outlet 12}. When the air outlet 12 is vented, the air pressure difference between the air outlet 12 and the air vent of the dust collection box 9 can cause the dust in the front space 4 to be adsorbed into the dust collection box under the action of negative pressure, thereby avoiding the accumulation of dust in the front space 4 and improving the dust collection effect.

[0111] In any of the above embodiments, the baffle 7 is a flexible baffle, and the filter screen 8 is a flexible filter screen;

[0112] Furthermore, such as Figure 2 and Figure 3 As shown, a rear space is defined between the rear part of the heat exchanger 2 and the rear part of the casing 1, and the volume of the rear space is smaller than the volume of the front space. That is, in this embodiment of the invention, the track is designed to make full use of the space between the front parts of the heat exchanger 2 and the casing 1.

[0113] like Figure 4 and Figure 5 As shown, a second aspect of this utility model embodiment also provides a control method for an air conditioner, including the aforementioned wall-mounted air conditioner indoor unit. The control method for the air conditioner includes:

[0114] Responding to the cleaning command from the air conditioner;

[0115] The baffle is moved in the first track to clean its surface by a cleaning mechanism; and / or

[0116] The filter screen is controlled to move in the second track to clean the surface of the filter screen by a cleaning mechanism.

[0117] Specifically, the baffle is moved in the first track to clean the baffle surface by a cleaning mechanism, including:

[0118] The first moving brush in the control cleaning mechanism rotates to the first cleaning position A, and the control baffle moves from the side section of the first track to the top section of the first track; and / or

[0119] The second moving brush in the control cleaning mechanism is rotated to the second cleaning position A, and the filter screen is moved from the side section of the second track to the top section of the second track.

[0120] In this embodiment of the invention, when cleaning the baffle 7 and the filter screen 8, by controlling the baffle 7 and the filter screen 8 to move from the side to the top, the cleaning mechanism can more easily make the cleaned dust fall into the dust collection box 9.

[0122] After the baffle stops moving, the first movable brush in the cleaning mechanism is controlled to rotate by a first preset angle, wherein the angle value of the first preset angle satisfies the following conditions: after the first movable brush rotates by the first preset angle, the first movable brush can pass through the first cleaning position B at least once; and / or

[0123] After the filter screen stops moving, the second moving brush in the cleaning mechanism is controlled to rotate by a second preset angle, wherein the angle value of the second preset angle satisfies that: after the second moving brush rotates by the second preset angle, the second moving brush can pass through the second cleaning position B at least once.

[0124] In this embodiment of the invention, self-cleaning of the first and second moving brushes can be achieved by controlling their rotation.

[0125] In any of the above embodiments, the control method for the air conditioner further includes:

[0126] When the air conditioner is turned off, the control baffle moves to the top section of the first track, and the control filter moves to the side section of the second track.

[0127] When the air conditioner is turned on, the control baffle moves from the top section of the first track to the side section of the first track, and the control filter moves from the side section of the second track to the top section of the second track.

[0128] In any of the above embodiments, the control method for the air conditioner further includes:

[0129] The cleaning command is executed when the air conditioner responds to the start and / or stop commands;

[0130] Air conditioner control methods also include:

[0131] Obtain the actual weight of the dust collection box and compare it with the preset weight value;

[0132] If the actual weight value is greater than the preset weight value, a reminder instruction to disassemble and clean the dust collection box will be issued.

[0133] To better understand the working principle of the air conditioner in this embodiment of the invention during dust removal, the following is a detailed explanation. Figures 1-5 Please provide a detailed explanation:

[0134] When the air conditioner is turned off, such as Figure 1 As shown, the flexible air inlet baffle 7 is located on one side of the air inlet 11 of the first track 5 {that is, the baffle 7 is located at the top section 51 of the first track 5}, and the flexible filter 8 is located on the side of the second track 6 away from the air inlet 11 {that is, the filter is located at the side section 62 of the second track 6}.

[0135] When the air conditioner is turned on, such as Figure 2 As shown, the second motor (not shown in the figure) drives the second roller to rotate clockwise, moving the flexible filter 8 from the side away from the air inlet 11 to the side of the air inlet 11; the first motor (not shown in the figure) drives the first roller to rotate counterclockwise, moving the flexible baffle 7 from the side of the air inlet 11 to the side away from the air inlet 11. The filter 8 and flexible baffle 7 stop moving after reaching the top of the other side. Assuming they move at a constant speed in the track, the movement times t1 and t2 of the flexible baffle 7 and filter 8 should satisfy t = (Ld) / a, where L1 is the length of the first track 5, d1 is the length of the flexible baffle 7, a1 is the rotational speed of the first roller, L2 is the length of the second track 6, d2 is the length of the filter 8, and a2 is the rotational speed of the second roller. To ensure that the filter 8 and flexible baffle 7 do not disengage during operation, the rollers (first roller and second roller) are positioned in the middle of the tracks (first track and second track), and d1 > L1 / 2, d2 > L2 / 2.

[0136] Brush assemblies are installed beside the movement tracks of the flexible air inlet baffle 7 and the flexible filter screen 8. Each brush assembly includes a movable brush, a fixed brush, and an aluminum rod. The movable brush is mounted on the rotatable aluminum rod, and the fixed brush is mounted on the opposite side wall. During the movement of the flexible baffle 7 and the filter screen 8, the second movable brush remains stationary and cleans the flexible filter screen 8. After the flexible filter screen 8 stops moving, the second aluminum rod rotates, causing the second movable brush to rotate one revolution, and the second fixed brush scrapes and cleans the second movable brush. Similarly, when the flexible air inlet baffle 7 moves, the first movable brush remains stationary and cleans the surface of the flexible air inlet baffle 7. After the flexible air inlet baffle 7 stops moving, the first aluminum rod rotates, causing the first movable brush to rotate one revolution, and the first fixed brush scrapes and cleans the first movable brush.

[0137] When the air conditioner stops running, the flexible air intake baffle 7 returns to its original position, allowing the first moving brush to clean it again; the flexible filter 8 also returns to its original position, allowing the second moving brush to clean it again. This ensures that the filter 8 and flexible air intake baffle 7 are cleaned every time the air conditioner is turned on and off, maintaining their cleanliness during operation. During the entire self-cleaning process, all dust and other debris falls into the first dust collection box 91 and the second dust collection box 92. After dust removal, the indoor unit checks if the weight of the dust collection boxes has reached a preset value; if so, it issues a reminder for the user to disassemble and clean the dust collection boxes.

[0138] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
