Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas treatment equipment, in particular to a wall-mounted air conditioner indoor unit. BACKGROUND

[0002] Air conditioners are ubiquitous in daily life, and the overall performance requirements of air conditioners are becoming higher and higher, especially the higher requirements for cleaning and dust removal of air conditioners and the quality of air blown by air conditioners.

[0003] After long-term use of the air conditioner, the dust on the filter screen of the indoor unit of the air conditioner will also gradually increase, which is easy to breed bacteria and cause the indoor air quality to decrease. Therefore, the user needs to clean the filter screen frequently, which is time-consuming and laborious.

[0004] At the same time, a large amount of harmful substances will be generated during the decoration of new houses or the installation of new furniture, which will affect people's health. The existing air conditioners with air purification function on the market mostly increase air purification modules at the air inlet of the air conditioner. However, the air purification module has a relatively large or small density compared to the ordinary filter screen, which reduces the air inlet amount and affects the air inlet and outlet effect of the air conditioner. SUMMARY

[0005] In order to overcome the problem that the filter screen in the existing air conditioner needs to be cleaned frequently, and the problem that the air purification module reduces the air inlet amount, the present application provides a wall-mounted air conditioner indoor unit, which moves the filter screen by controlling the filter screen and sets a dust removal module capable of cleaning the moving filter screen, to solve the problem of frequent cleaning of the filter screen.

[0052] To overcome the problems of the need for constant cleaning of filters in existing air conditioners and the reduced air intake caused by air purification modules, this application provides a wall-mounted air conditioner indoor unit. This unit controls the movement of the filter and includes a dust removal module capable of cleaning the moving filter, thus solving the problem of frequent filter cleaning. Simultaneously, a movable air purification module is provided. When air purification is not required, the air purification module can be moved to a position that avoids the air intake, thereby ensuring the air intake of the air conditioner.

[0053] Specifically, such as Figures 1-4 As shown in the figure, an embodiment of the present invention proposes a wall-mounted air conditioner indoor unit, comprising:

[0054] The body 300 has an air inlet 301 formed on its top;

[0055] The first track 100 and the second track 200, the first track 100 includes a first track segment A101 opposite to the air inlet 301 and a first track segment B102 that avoids the air inlet 301, the second track 200 includes a second track segment A201 opposite to the air inlet 301 and a second track segment B202 that avoids the air inlet 301.

[0056] The filter 400 and the air purification module 500 are movably disposed within the first track 100. When moving, the filter 400 has a first position A in the first track segment A101 corresponding to the air inlet 301 and a first position B in the first track segment B102 to avoid the air inlet 301. The air purification module 500 is movably disposed within the second track 200. When moving, the air purification module 500 disposed within the second track 200 has a second position A in the second track segment A201 corresponding to the air inlet 301 and a second position B in the second track segment B202 to avoid at least a portion of the air inlet 301.

[0057] Dust removal module 600 is used to clean the moving filter screen 400.

[0058] In this embodiment, by controlling the movement of the filter 400 within the first track 100 and setting a dust removal module 600 capable of cleaning the moving filter 400, the problem of frequent cleaning of the filter 400 can be solved. At the same time, an air purification module 500 that can move within the second track 200 is set. When air purification is not required, the air purification module 500 can be moved to a position that avoids the air conditioner air inlet 301, thereby ensuring the air intake of the air conditioner.

[0059] It should be noted that the air purification module mentioned in the embodiments of this application can be any air purification module with air purification function, such as a formaldehyde removal module or a benzene removal module.

[0060] It should also be noted that when the filter 400 is in the first position A of the corresponding air inlet 301 mentioned in this application embodiment, it means that the filter 400 completely blocks the air inlet 301. Similarly, when the air purification module 500 is in the second position A of the corresponding air inlet 301 mentioned in this application embodiment, it means that the air purification module 400 completely blocks the air inlet 301. Completely blocking the air inlet 301 does not require a perfectly tight seal; a blocking error between 1mm and 5mm is considered complete blocking.

[0061] It should also be noted that the first track segment B102 mentioned in the embodiments of this application to avoid the air inlet 301 refers to the fact that the projection of the first track segment B102 in the vertical direction of the body 300 does not coincide with the projection of the air inlet 301 in the vertical direction. Similarly, the second track segment B202 mentioned in the embodiments of this application to avoid the air inlet 301 refers to the fact that the projection of the second track segment B202 in the vertical direction of the body 300 also does not coincide with the projection of the air inlet 301 in the vertical direction.

[0062] It should be noted that in the embodiments of this application, the first track segment A101 and the second track 200 have the same trend in the extension direction. That is, if the first track segment A101 extends along the front-back direction of the body, then the second track 200 also extends along the front-back direction of the body. If the first track segment A101 extends along the left-right direction of the body, then the second track 200 also extends along the left-right direction of the body.

[0063] In some implementations, such as Figures 1-3 As shown, the indoor unit of the wall-mounted air conditioner also includes:

[0064] Heat exchanger 700, the top of heat exchanger 700 and air inlet 301 define a top space, the side of heat exchanger 700 and the side of body 300 define a side space.

[0065] The second track 200 is constructed as an inclined track, and the inclined second track 200 extends downward from the top space side to the side space side.

[0066] It should be noted that the filter screen 400 in this embodiment is a flexible filter screen, which can move back and forth in the first track segment A101 and the first track segment B102 in different extension directions, and achieve the cleaning effect of the filter screen by contacting the dust removal module 600 during the movement.

[0067] Unlike the filter 500, the air purification module 500 cannot be made flexible, so it cannot move in different directions along the track.

[0068] Based on this, in this embodiment, the second track 200 is constructed as an inclined track, and extends inclinedly downward from the top space to the side space. On the one hand, setting the second track 200 as a straight track can satisfy the movement effect of the air purification module 500, thereby achieving the blocking and avoidance of the air inlet 301. On the other hand, by extending the second track inclinedly to the side space, the internal space of the unit 300 is fully utilized, thus ensuring the movement effect of the air purification module 500 while avoiding the indoor unit becoming too large. Figures 1-3 As shown, if the second track 200 is set horizontally, the front-to-back dimensions of the body 300 will be too large.

[0069] It should also be noted that the tilted second track 200 mentioned in the embodiments of this application is tilted relative to the first track segment A101. That is, if the first track segment A101 extends horizontally in the front-rear direction of the body, then the second track 200 extends tilted in the front-rear direction of the body. If the first track segment A101 extends horizontally in the left-right direction of the body, then the second track 200 extends tilted in the left-right direction of the body.

[0070] In some implementations, such as Figures 1-3 As shown, the side of the heat exchanger 700 includes at least an inclined heat exchange portion 701 that extends downward, and the inclined heat exchange portion 701 and the side of the body 300 define a side space that gradually narrows from top to bottom.

[0071] The second track 200, which extends at least partially downwards at an angle, is located within a tapering lateral space.

[0072] As can be seen, the second track 200 in this embodiment of the application fully takes into account the specific shape of the heat exchanger 700 and the side space of the body 300 when they are fitted together, so as to make full use of the side space to arrange the second track 200.

[0073] In some implementations, such as Figure 1 As shown, the inclined heat exchange portion 701 of the heat exchanger 700 forms an angle α with the horizontal plane;

[0074] The inclined second track 200 forms an angle b with the horizontal plane;

[0075] The size of the included angle b is positively correlated with the size of the included angle a. Preferably, the included angle a > the included angle b.

[0076] In this embodiment, the second track 200, which is inclined, forms a certain angle with the first track segment B of the first track 100. The angle of this angle depends on the shape of the heat exchanger. In other words, in this embodiment, the shape of the heat exchanger 700 is fully considered when setting the inclination angle of the second track 200, so as to maximize the use of the space formed between the heat exchanger 700 and the body 300 while ensuring the air purification effect.

[0077] In some implementations, such as Figures 1-3 As shown, the heat exchanger 700 has a front heat exchange section opposite to the front side of the body 300 and a rear heat exchange section opposite to the rear side of the body 300. The side space includes a front space defined between the front heat exchange section and the front side of the body 300, and a rear space defined between the rear heat exchange section and the rear side of the body 300, wherein the front space is larger than the rear space.

[0078] At least a portion of the front heat exchange section is formed with an inclined heat exchange portion 701 to create a front space that is at least partially tapered on the front side of the body 300.

[0079] The second track 200 extends downwards from the rear of the body 300 to the tapering area of ​​the front space.

[0080] In this embodiment, the front space inside the body 300 is larger than the rear space inside the body 300. Based on this, in order to make full use of the larger front space, the second track 200 is extended to the front space, which can make full use of the extra space inside the body 300, thereby avoiding the body 300 from being too large.

[0081] In some implementations, such as Figures 1-3 As shown, in order to further utilize the internal space of the body 300, in this embodiment of the application, the first track segment A101 is set to extend in the front-rear direction of the body 300, the first track segment B102 is set to extend in the vertical direction of the body 300, and the upper end of the first track segment B102 is connected to the first track segment A101 extending to one end of the front side of the body 300.

[0082] The second track 200 is placed below the first track segment A101, and the second track 200 and the first track segment B102 are arranged to intersect and connect with each other.

[0083] In this embodiment, the first track 100 and the second track 200 share a common section of track. This arrangement allows for the maximum maximization of the width of the air inlet 301 (i.e., the air inlet 101 can be made very large in the front-to-back direction) without affecting the movement of the filter 400 in the first track 100 or the air handling module 500 in the second track 200. Furthermore, while maximizing the width of the air inlet 301, it also ensures that the air handling module 500 can effectively block and avoid obstruction of the air inlet 301 during movement.

[0084] Specifically, in some implementation methods, such as Figures 1-3 As shown, a connecting track 800 is provided between the second track segment A201 corresponding to the air inlet 301 and the second track segment B202 that avoids the air inlet 301.

[0085] The first track segment B102, which avoids the air inlet 301, includes a first track segment B11021 located above the connecting track 800 and a first track segment B21022 located below the connecting track 800, and the first track segment B11021 and the first track segment B21022 are connected through the connecting track 800.

[0086] so:

[0087] When the filter 400 is in the horizontally positioned first track section A, if air purification is required, the air purification module 500 can be moved to the second track section A to achieve filtration and purification of the incoming airflow. Figure 2 As shown.

[0088] When the filter 400 is in the horizontally set first track section A, if air purification is not required, at least part of the air purification module 500 can be moved to the second track section B to filter the incoming airflow while avoiding the air purification module 500 affecting the air intake volume.

[0089] When the filter 400 needs to be cleaned, it can be moved from the horizontally set first track section A101 to the vertically set first track section B102. The dust removal module 600 cleans the moving filter 400, and at the same time, the air purification module 500 is moved to the second track section A corresponding to the air inlet 301. This way, the air purification module 500 can be cleaned while avoiding affecting the movement of the filter 400. In addition, the air purification module 500 set in the second track section A can also temporarily intercept impurities and dust outside the machine body 300, thereby preventing impurities and dust outside the machine body 300 from entering the machine body 300.

[0090] In some implementations, such as Figures 1-3 As shown, the wall-mounted air conditioner indoor unit also includes:

[0091] Dust collection module 900 is used to collect dust that falls off after cleaning filter screen 400.

[0092] In this embodiment, a dust collection module 900 is provided in the body 300 to facilitate the collection of dust that falls off when cleaning the filter screen 400.

[0093] Specifically, in some implementation methods, such as Figures 1-3 As shown, the dust removal module 600 includes a movable brush 601 and a fixed brush 602. When the movable brush 601 is controlled to move, it has a first moving position that contacts the filter screen 400 and a second moving position that contacts the fixed brush 602. When the movable brush 601 is in the first moving position, it is used to clean the filter screen 400. When the movable brush 602 is in the second moving position, it can contact the fixed brush 602 to achieve self-cleaning of the movable brush 601.

[0094] The dust collection module 900 includes a dust collection box located at the bottom of the moving brush 601 and having an opening at the top. The dust collection box is used to collect dust that falls off the moving brush 601 when cleaning the filter screen 400 and / or to collect dust that falls off the moving brush 601 during self-cleaning.

[0095] In other words, the movable brush 601 in this embodiment can clean the filter screen 400 and can also work with the fixed brush 602 to achieve a self-cleaning effect.

[0096] It is worth noting that the dust collection module 900 in this embodiment is detachably mounted on the body 300 to facilitate cleaning of the dust collection module 900 by users or maintenance personnel.

[0097] In some implementations, the wall-mounted air conditioner indoor unit also includes:

[0098] The drive module includes a first roller 10 for driving the filter 400 to move, and a second roller 20 for driving the air purification module 500 to move.

[0099] in

[0100] The first roller 10 is located between the first track section A101 and the first track section B102, and the first roller 101 has first gears formed on both sides of the machine body 300 in the length direction. The filter screen 400 has first racks on both sides of the machine body 300 in the length direction. The first gears and the first racks mesh.

[0101] The second roller 20 is located below the second track 200, and the second roller 20 has second gears on both sides of the body 300 along its length. The air purification module 500 has second racks on both sides of the body 300 along its length, and the second gears and second racks mesh with each other.

[0102] In some implementations, such as Figure 4 As shown, the air purification module 500 described above includes:

[0103] An air purification module frame 501 is disposed within a second track 200, and the frame 501 has a movable part that cooperates with the second track 200, and a receiving part that is opposite to the movable part and faces the air inlet 301.

[0104] The air purification module body 502 is located in the receiving part and is used to purify the airflow at the air inlet 301.

[0105] Specifically, the air purification module frame 501 has toothed strips on both sides of the body 300 along its length, and the air purification module body 502 is located inside the air purification module frame 501.

[0106] More specifically, in some embodiments, the air purifier body 502 includes a purification section for purifying formaldehyde in the airflow, and an active metal catalyst disposed on the surface of the purification section. The purification section has a honeycomb structure made of silica composite material and is used to purify formaldehyde in the air; the active metal catalyst is attached to the surface of the purification section.

[0107] To better understand the working principle of the wall-mounted air conditioner indoor unit in the embodiments of this application, the following is a detailed explanation. Figures 1-4 The operating control logic of the air conditioner during dust removal and formaldehyde removal is explained in detail below:

[0108] like Figure 4 As shown, when the air conditioner is turned on, the flexible dust removal filter is located on the air inlet side of the dust removal track, that is, the flexible filter 400 is located in the first track section A101. The formaldehyde removal module is located on the side of the formaldehyde removal track away from the air inlet, that is, the air purification module 500 is at least partially moved to the second track section B202 to at least partially avoid the air inlet 301, so as to ensure the air intake of the air conditioner. At this time, the filter 400 is checked for dirt and clogging. If the dust removal filter 400 needs to be cleaned, the second roller 20 motor is started first, driving the formaldehyde removal module to the air inlet side, so that the air purification module 500 moves to the second track section A201 that blocks the air inlet, so as to avoid the movement path of the filter 400. Then the first roller 10 motor is started, driving the filter 400 to the side away from the air inlet, that is, controlling the filter 400 to move to the first track section B102 that avoids the air inlet 301, for cleaning and dust removal of the filter.

[0109] Then, the indoor formaldehyde content is detected to determine if it is greater than or equal to the preset value 'a'. If it is greater than 'a', the dust filter is reset (i.e., the filter 400 moves to the first track segment A101 that blocks the air inlet 301), and the formaldehyde removal mode is activated. The formaldehyde value is detected again every T time period until it is less than the preset value 'a'. If the formaldehyde content detected at the beginning is less than 'a', the dust filter 400 is reset, and the formaldehyde removal module is reset (i.e., the air purification module 500 is moved to the second track segment A201 that avoids the air inlet 301), and no formaldehyde removal is required.

[0110] If the initial filter 400 is determined to be clogged and therefore does not require cleaning, then indoor formaldehyde levels are tested. If the measured value is less than 'a', the air conditioner operates normally. If the value is greater than or equal to 'a', the second roller motor (20) starts, moving the formaldehyde removal module to the air inlet side to remove formaldehyde. Indoor formaldehyde levels are checked every T time interval until the value falls below the preset value 'a', at which point formaldehyde removal is complete, and the formaldehyde removal filter resets. Throughout the process, dust and other debris swept by the filter and brush fall into the dust collection box. The indoor unit uses a preset sensor to determine if the weight of the dust collection box has reached a preset value. If it does, a reminder is issued, and the user is instructed to remove and clean the dust collection box.
