[0055] Background

[0056] As consumers have higher and higher requirements for air conditioner performance and functions, it is necessary to design air conditioners with novel and convenient functions to meet user needs. The existing automatic dust removal of the filter is designed at the air inlet position, and the dust removal of the filter is achieved by the left and right movement of the filter.

[0057] However, existing room types often have larger living rooms and smaller bedrooms. Therefore, the left-right dust removal solution has problems such as a long dust removal cycle, the need to increase the length of the entire machine, and incompatibility with the indoor environment.

[0058] Example 1

[0059] Based on this, Figure 1-Figure 4 As shown, in a first aspect, embodiment 1 of the present application provides a wall-mounted air conditioner indoor unit, comprising:

[0060] A machine body 10, wherein an air inlet is provided on the top of the machine body 10;

[0061] A heat exchanger, which is disposed inside the body 10 and defines a receiving space between the heat exchanger and the air inlet;

[0062] The filter assembly 20 is arranged in the accommodation space between the heat exchanger and the air inlet, and is used to filter the airflow before passing through the heat exchanger. The filter assembly 20 includes a plurality of independently arranged filter modules 200, and the plurality of filter modules 200 are sequentially distributed along the length direction of the air inlet, and each filter module 200 includes a movable filter screen 201;

[0063] A cleaning component 30, the cleaning component 30 is configured to clean the filter screen 201 in motion;

[0064] The multiple filter screens 201 in the multiple filter modules 200 can be selectively controlled to move according to their dirty or blocked conditions, and the cleaning component 30 is used to clean the moving filter screens 201;

[0065] Preferably, the plurality of filter modules include a first filter module and a second filter module, and the first filter module and the second filter module are arranged on the left and right sides of the air inlet along the length direction of the air inlet and can be controlled to be cleaned independently or simultaneously;

[0066] Further preferably, each filter module is designed as a reciprocating filter screen, and the cleaning assembly 30 is disposed between two adjacent filter screen modules, and can be controlled to clean the two adjacent filter screen modules individually or simultaneously.

[0067] In the embodiment of the present application, multiple filter modules 200 are set, and each filter module 20 is independently set. In this way, when the filter net 201 in the filter module 20 is dirty and blocked, the movement of the filter net 201 in the filter module 200 can be controlled individually, and it can be cleaned in combination with the cleaning component 30. Compared with the filter net in the existing filter module, the filter net 201 in each filter module 200 in the embodiment of the present application has a shorter running time during cleaning, and the filter net 201 in each filter module 200 can operate independently, which can greatly reduce the downtime waiting time when cleaning the filter net 201, thereby reducing the time consumed when cleaning the filter net 201 and improving the user experience.

[0068] Further, such as Figure 1-Figure 4 As shown, the filter module 200 further includes two rollers 202 distributed in the length direction of the air inlet, both rollers 202 cooperate with the filter screen 201, and the filter screen 201 can be driven to perform circumferential movement between the two rollers 202 by controlling the rotation of at least one roller 202;

[0069] The cleaning assembly 30 includes a cleaning brush 301 disposed beside at least one roller 202, and a dust collection box 302 disposed below the cleaning brush 301;

[0070] When the filter 201 is driven to perform circumferential motion between the two rollers 202, the cleaning brush 301 located beside the roller 202 can clean the filter 201 matched on the roller 202, and the dust box 302 is used to collect dust dropped after cleaning.

[0071] In the embodiment of the present application, two rollers 202 are provided, and the filter 201 is arranged to perform circumferential motion around the roller 202, synchronously cooperating with the cleaning brush 301 and the dust box 302 arranged next to the roller 202, so that when the filter 201 is moving, the cleaning brush 301 can clean the surface of the filter 201, and the dust box 302 can collect the dust that falls after cleaning.

[0072] Further, in some possible implementations, such as Figure 2-Figure 4 As shown, the cleaning brush 301 includes a first cleaning brush 3011 and a second cleaning brush 3012 distributed up and down;

[0073] When the filter screen 201 is driven to perform circumferential motion between the two rollers 202 , the first cleaning brush 3011 and the second cleaning brush 3012 distributed up and down can clean the filter screen 201 matched on the rollers 202 twice.

[0074] In the embodiment of the present application, two cleaning brushes are arranged in upper and lower distributions, so that when the filter 201 moves to the position of the drum 202, the two cleaning brushes can clean the same position of the filter 201 twice, thereby improving the cleaning effect of the filter.

[0075] It is worth noting that the cleaning of the same position of the filter 201 twice mentioned in the embodiment of the present application does not require the filter 201 to move twice repeatedly, thereby saving the running time of the filter 201 and improving the cleaning effect of the filter 201. At the same time, the two cleaning brushes distributed above and below the drum 202 will not occupy much space inside the air conditioner, thereby improving the cleaning effect of the filter 201 while ensuring the size of the air conditioner.

[0076] Further, in some possible implementations, such as Figure 2-Figure 4 As shown, the first cleaning brush 3011 is a first brush with bristles arranged at the bottom end;

[0077] The second cleaning brush 3012 is a second brush with bristles arranged circumferentially;

[0078] The second brush can be controlled to rotate, and when the second brush rotates, its bristles can contact and cooperate with the bristles of the first brush, so as to achieve self-cleaning of the first brush and the second brush through the contact and cooperation between the two.

[0079] In the embodiment of the present application, the second cleaning brush 3012 located below is configured as a second brush with bristles circumferentially arranged and rotatable. In this way, when the second cleaning brush 3012 rotates, the self-cleaning effect of the first cleaning brush 3011 and the second cleaning brush 3012 can be achieved, thereby eliminating the need for manual cleaning of the cleaning brushes.

[0080] Further, in some possible implementations, such as Figure 2-Figure 4 As shown, the first cleaning brush 3011 can also translate along the length direction of the air inlet;

[0081] The interference amount between the first cleaning brush 3011 and the filter screen 201 can be changed by controlling the translation of the first cleaning brush 3011 .

[0082] In the embodiment of the present application, by controlling the first cleaning brush 3011 located at the top to translate, the interference amount between the first cleaning brush 3011 and the filter 201 can be changed, thereby achieving different degrees of cleaning of the filter 201.

[0083] It is worth noting that if Figure 2-Figure 4 As shown, the first cleaning brush 3011 in the embodiment of the present application only needs to translate a small distance, and does not need to translate a large distance. This ensures that while changing the interference amount between the first cleaning brush 3011 and the filter 201, the dust cleaned by the first cleaning brush 301 can still fall into the dust box 302 at the bottom of the first cleaning brush 3011.

[0084] Further, in some possible implementations, such as Figure 2-Figure 4 As shown, the cleaning assembly 30 is disposed between two adjacent filter modules 200 arranged along the length direction of the air inlet, so that the filter screens 201 in the two filter modules 200 can be cleaned by one cleaning assembly 30 .

[0085] In the embodiment of the present application, by setting the cleaning component 30 between the two filter modules 200, the filter screens 201 in the two filter modules 200 can be cleaned by one cleaning component 30, thereby ensuring the cleaning effect of the filter screens 201 while avoiding the problem of increasing the size of the air conditioner and the cost due to the addition of the cleaning component 30.

[0086] Further, in some possible implementations, such as Figure 2 As shown, the filter screen 201 is an annular flexible filter screen member sleeved between two rollers 202;

[0087] By controlling the rotation of at least one roller 202 , the filter screen 201 can be driven to perform circumferential motion between the two rollers 202 .

[0088] like Figure 2As shown, in the embodiment of the present application, the filter 201 is configured as an annular flexible filter element that can rotate 360° around the two rollers 202, so that the cleaning effect of the filter 201 can be achieved by controlling the rotation of one of the two rollers 202. At the same time, when controlling the rotation of the roller 202, it is only necessary to control the roller 202 to rotate in one direction to achieve an all-round cleaning effect on the filter 201. At the same time, when the filter 201 is configured as an annular flexible filter element that can rotate 360° around the two rollers 202, there is no need to set a filter track for the movement of the filter 201 in the body, because the two rollers 202 can already define a predetermined motion trajectory of the filter 201 when it moves, so there is no need to set a filter track to limit the movement of the filter 201.

[0089] Of course, in some alternative embodiments, a filter track may be added to further improve the stability of the filter 201 when moving.

[0090] Further, in some possible embodiments, the front side of the body 10 is further provided with a mounting opening extending toward the rear side of the body 10 {not shown in the figure};

[0091] The filter module 200 can be installed in the body 10 through the installation opening.

[0092] In the embodiment of the present application, an installation opening of the filter module 200 is provided on the front side of the machine body, so that when the filter 201 is dirty and clogged, the filter module 200 having the drum 202 and the filter 201 can be directly taken out for manual cleaning, thereby providing another more convenient way to clean the filter.

[0093] Specifically, the user can directly remove the filter screen for self-cleaning when the machine is turned off. When the user reinstalls the machine, guides are provided on both sides of the machine body installation opening. The user only needs to push the filter module 200 into the installation opening from the front to the back. A magnet is provided inside the installation opening. When the roller 202 moves into place, it is attracted by the magnet and automatically aligned to ensure that the rollers 202 on both sides are installed in place. On this basis, Figure 2-Figure 4 As shown, when disassembling, the lock buckle on the roller seat is directly turned on when the machine is turned off, and the roller 202 is pulled out for replacement.

[0094] Further, in some possible implementations, such as Figure 1-Figure 4 As shown, the filter assembly 20 includes two filter modules 200 distributed along the length direction of the air inlet;

[0095] The cleaning assembly 30 is disposed between the two filter modules 200 .

[0096] Specifically, the dust removal mode of the air conditioner indoor unit in the embodiment of the present application is as follows:

[0097] When the indoor unit is turned on, the dirty or blocked condition of the left filter is detected {by monitoring the air volume}. If it does not exceed the set value, the left filter is relatively clean and does not need to be cleaned; if it exceeds the set value, the dirty or blocked condition of the right filter is further detected. If the right filter does not exceed the set value either, the right filter is relatively clean and does not need to be cleaned. At the same time, the cleaning mode of the left filter is turned on {controlling the movement of the filter}. After cleaning, the indoor unit starts and runs normally. If the right filter is also dirty or blocked, the cleaning modes are turned on on both sides at the same time. After cleaning, the indoor unit starts and runs normally. If the dirty or blocked condition of the filter 201 still exceeds the set value after cleaning, the second cleaning brush 3012 located at the lower side also starts to clean the filter 201. It is worth noting that the second cleaning brush 3012 can have a cleaning position that cooperates with the filter and an idle position that does not cooperate with the filter when rotating.

[0098] After the filter 201 is cleaned, it is determined whether the first cleaning brush 3011 on the upper side needs to start self-cleaning {through weight monitoring}. If not, the filter 301 returns to the initial position, the second cleaning brush on the lower side returns to the initial position {i.e., the idle position mentioned above}, and the indoor unit is turned on and off normally; if self-cleaning needs to be turned on, the second cleaning brush 3012 on the lower side rotates to clean the first cleaning brush 3011 on the upper side, and the dust falls into the dust collection box 302 below.

[0099] Furthermore, the second aspect of Example 1 of the present application also provides an air conditioner, which includes the air conditioner indoor unit provided by the first aspect of Example 1 of the present application.

[0100] Example 2

[0101] The difference between this embodiment and embodiment 1 is that the setting form of the filter screen 201 in the embodiment of the present application is different from the setting form of the filter screen in embodiment 1.

[0102] According to the content of Example 1, the filter screen 201 in Example 1 is designed as an annular flexible filter screen member that does not need to install a filter screen track, while the filter screen 201 in this embodiment is different. Figure 3 and Figure 4 As shown, the filter screen 201 in this embodiment is designed to be a planar flexible filter screen member that is laid between two rollers 202 and meshes with the two rollers 202;

[0103] At the same time, the filter module 200 also includes a filter track for the filter 201 to move, the filter track includes an upper track segment and a lower track segment arranged corresponding to the air inlet, the upper track segment and the lower track segment extend in the length direction of the air inlet, and are connected together at the position of the two rollers 202 to form a ring-shaped filter track;

[0104] The filter screen 201 is arranged in the filter screen track, and by controlling the rotation of at least one roller 202, the filter screen 201 can be moved to a first filtering position placed in the upper track segment or to a second filtering position placed in the lower track segment;

[0105] When the filter net 201 moves to the filtering position placed in one of the track segments, at least a portion of the other track segment is not blocked by the filter net 201 .

[0106] That is, in this embodiment, the filter screen 201 is arranged as a planar flexible filter screen member that is laid between the two rollers 202 and meshed with the two rollers 202 , and accordingly, a filter screen track for the filter screen 201 to move needs to be arranged in the machine body 10 .

[0107] However, it should be noted that, although the filter track in this embodiment will increase the production cost of the air conditioner accordingly, correspondingly, when the filter 201 in the embodiment of the present application moves to the filtering position in one of the track segments, at least part of the other track segment is not blocked by the filter 201, which can also achieve the effect of increasing the air intake, that is, when the filter in Example 1 filters the airflow at the air inlet, the double-layer filter surface is used to filter the airflow. Although the filtering effect is improved, the air intake will be affected accordingly. When the filter in this embodiment filters the airflow at the air inlet, only one of the upper and lower track segments is provided with a filter, thereby increasing the airflow entering the machine body from the air inlet.

[0108] Further, such as Figure 3 and Figure 4 As shown, the two drums 202 in the filter module 200 include a first drum disposed close to the cleaning assembly 30 and a second drum disposed away from the cleaning assembly 30;

[0109] The filter screen 201 can be controlled to switch between the first filtering position and the second filtering position by controlling the forward and reverse rotation of the first drum.

[0110] In this embodiment 2, illustratively, Figure 3 and Figure 4 The structures and combinations indicated by the reference numerals in Figure 5 The working mode of the filter assembly provided in this embodiment can support filtering mode, air volume increase mode and cleaning mode. Figure 5 The left picture shows the filtering mode of the filter, that is, the filter blocks the entire air inlet. This mode is usually suitable for situations where indoor air quality does not meet the standard. Figure 5The middle figure shows the increased air volume mode of the filter. In this mode, for example, when the indoor air quality is detected to be good, the filter can be controlled to move so that the middle position of the air inlet is opened, thereby increasing the air volume. Figure 5 The right side figure shows the cleaning mode, in which the filter screen is driven along the track to perform circumferential movement between the two rollers, and contacts the cleaning brush during the axial movement, thereby achieving cleaning.

For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.
