[0002] The dust removal method of ordinary air conditioners is mainly to use air filters installed near the air inlet to absorb dust in the air, but too much dust on the filter will bring many negative effects. For example, too much dust will cause the filter mesh to be blocked, resulting in poor ventilation, affecting the cooling and heating effects, greatly reducing the air conditioning capacity, and increasing operating costs. At the same time, some dust on the filter may re-enter the indoor air with the circulating airflow, affecting the indoor air quality, which is inconsistent with the healthy function of the air conditioner.

[0054] Background

[0055] The dust removal method of ordinary air conditioners is mainly to use air filters installed near the air inlet to absorb dust in the air, but too much dust on the filter will bring many negative effects. For example, too much dust will cause the filter mesh to be blocked, resulting in poor ventilation, affecting the cooling and heating effects, greatly reducing the air conditioning capacity, and increasing operating costs. At the same time, some dust on the filter may re-enter the indoor air with the circulating airflow, affecting the indoor air quality, which is inconsistent with the healthy function of the air conditioner. Therefore, how to remove dust on the air conditioner filter has become a common concern for users and air conditioner manufacturers.

[0056] Therefore, after using the air conditioner for a period of time, the indoor unit filter and the air inlet baffle need to be cleaned. In the prior art, the air conditioner is cleaned manually, which is time-consuming and labor-intensive. The various parts of the air conditioner need to be disassembled for cleaning. After cleaning, the various parts need to be reassembled, which is quite cumbersome.

[0057] Based on this, Figure 1-Figure 4 As shown, the first aspect of the embodiment of the present application provides a wall-mounted air conditioner indoor unit, comprising:

[0058] The body 100 has an air inlet 101 at the top thereof;

[0059] The filter assembly includes an annular filter track 200 disposed inside the body, and an annular filter 300 capable of moving in the annular filter track 200. The annular filter 300 cooperates with the annular filter track 200 on both sides in the width direction and is divided into a filter section 301 with mesh and a hollow section 302 without mesh in the length direction.

[0060] A driving assembly 400 and a cleaning assembly 500, wherein the driving assembly 400 is used to drive the annular filter screen 300 to move in the annular filter screen track 200, and the cleaning assembly 500 is used to clean the surface of the filter section 301 of the annular filter screen 300 when the annular filter screen 300 moves;

[0061] The annular filter mesh track 200 includes an air inlet track segment 201 arranged corresponding to the air inlet, and the air inlet track segment 201 includes an outer air inlet track segment 2011 arranged close to the air inlet 101 and an inner air inlet track segment 2012 arranged away from the air inlet 101, wherein one of the outer air inlet track segment 2011 and the inner air inlet track segment 2012 corresponds to the filter segment 301 of the annular filter mesh 300, and the other corresponds to the hollow segment 302 of the annular filter mesh 300.

[0062] In the embodiment of the present application, an annular filter track and an annular filter that can move in the annular filter track are arranged in the machine body, and relevant driving components and cleaning components are provided at the same time, so that the annular filter can be cleaned by the cleaning component when it moves in the annular filter track. At the same time, the annular filter in the embodiment of the present application includes a filter section with mesh and a hollow section without mesh, and when one of the outer air inlet track section and the inner air inlet track section corresponding to the air inlet corresponds to the filter section of the annular filter, the other corresponds to the hollow section of the annular filter, thereby ensuring effective filtering of the airflow at the air inlet while avoiding the problem of affecting the air intake of the air inlet due to the filter sections corresponding to the outer air inlet track section and the inner air inlet track section.

[0063] Further, in some possible implementations, such as Figure 4 As shown, the annular filter net 300 has a plurality of filter segments 301 and a plurality of hollow segments 302, and the plurality of filter segments 301 and the plurality of hollow segments 302 are sequentially staggered in the length direction of the annular filter net 300;

[0064] The length of the filter section 301 and the length of the hollow section 302 are designed to satisfy: when one of the outer air inlet track section 2011 and the inner air inlet track section 2012 corresponds to the filter section 301 , the other corresponds to the hollow section 302 .

[0065] In the embodiment of the present application, the annular filter net 300 is provided with a plurality of filter segments 301 and a plurality of hollow segments 302, and the length of the filter segment 301 and the length of the hollow segment 302 are designed such that when one of the outer air inlet track segment 2011 and the inner air inlet track segment 2012 corresponds to the filter segment 301, the other corresponds to the hollow segment 302. In this way, there can always be a filter segment 301 at the position corresponding to the air inlet 101 to filter the airflow at the air inlet 101. Specifically, as Figure 1-Figure 3 As shown, when the filter segment 301 in the outer air inlet track segment 2011 is dirty and needs to be cleaned, the annular filter 300 can be driven to move clockwise. At this time, the filter segment 301 in the outer air inlet track segment 2011 moves to a position avoiding the air inlet 101, and the filter segment 301 in the position avoiding the air inlet 101 moves to the inner air inlet track segment 2012 corresponding to the air inlet 101. That is, when the annular filter is cleaned, there is always a filter segment 301 at the position corresponding to the air inlet 101 to filter the airflow, so there is no need to shut down the air conditioner indoor unit when cleaning the filter.

[0066] Further, in some possible embodiments, the annular filter track 200 further includes a dust removal track segment 202 that avoids the air inlet 101 and extends in the up-down direction of the body 100, the dust removal track segment 202 includes an outer dust removal track segment 2021 that is close to the outside of the body 100 and an inner dust removal track segment 2022 that is far from the outside of the body 100, and the outer air inlet track segment 2011, the outer dust removal track segment 2021, the inner dust removal track segment 2022 and the inner air inlet track segment 2012 are sequentially connected together to form the annular filter track 200;

[0067] The cleaning component 500 is used to clean the filter segment 301 when the filter segment 301 of the annular filter 300 moves into the dust removal track segment 202. The air conditioner indoor unit also includes a dust collecting component 600 arranged at the bottom of the dust removal track segment 202. The dust collecting component 600 is used to collect hair debris that falls downward when the cleaning component 500 cleans the filter segment 301.

[0068] In the embodiment of the present application, the annular filter mesh track 200 is arranged to be an air inlet track section 201 corresponding to the air inlet 101 and a dust removal track section 202 avoiding the air inlet 101. In this way, when the filter section 301 in the air inlet track section 201 is removed, the filter section 301 can enter the dust removal track section 202 avoiding the air inlet 101, and be cleaned by the cleaning component 500. The cleaned capillaries can fall directly into the dust collecting component 600 at the bottom under the action of gravity, thereby realizing the collection of dust and hair debris.

[0069] Preferably, the dust collecting assembly 600 is a dust collecting box which is arranged at the bottom of the dust removal track segment 201 and has an opening at the top.

[0070] Further, in some possible implementations, such as Figure 1 and Figure 4 As shown, the width of the outer air inlet track section 2011 is L;

[0071] The lengths of the multiple filter segments 301 and the multiple hollow segments 302 of the annular filter net 300 are the same and equal to the length L of the outer air inlet track segment 2011 .

[0072] Preferably, Figure 4 As shown, the annular filter screen 300 includes two filter segments 301 and two hollow segments.

[0073] That is, in the embodiment of the present application, the annular filter 300 is divided into four sections of equal length, including the first filter section L1, the second filter section L2, the first hollow section L3 and the second hollow section L4, that is, one filter section, one hollow section, one filter section and one hollow section. A driving assembly {preferably a drum} is used to drive the annular filter 300, so that the two filter sections 301 of the annular filter 300 can be used alternately during the self-cleaning and dust removal process of the filter. After the air conditioner is turned on, the current degree of dirtiness and blockage of the filter is detected. If the dirtiness and blockage are qualified, the filter does not need to be operated and can be used directly. If the dirtiness and blockage are unqualified, the filter assembly runs a distance and realizes the cleaning of the filter, and then the machine is turned on for use, with high cleaning efficiency. Through logical control, it can be realized that the clean filter can be quickly replaced, and the filter can also be fully cleaned, and the cleaning is more thorough.

[0074] Specifically, the control logic of the operation process is as follows: the air conditioner is turned on, and it is assumed that there is a first filter segment L1 in the external air inlet track segment 2011, and the degree of dirtiness and blockage of the first filter segment L1 is judged, and the transmittance M1 is ≤ 70% {wherein the transmittance reaches 70% or more for the usable state}, if the transmittance is qualified, it will operate normally, if it is unqualified, such as Figure 1-Figure 3As shown, the inner cleaning brush in the inner cleaning component 502 rotates 90° clockwise, the inner cleaning brush contacts the second filter segment L2, the drum drives the annular filter screen to run L distance clockwise, the first filter segment L1 runs into the outer dust removal track segment 2021, the second filter segment L2 runs to the inner air inlet track segment 2012 corresponding to the air inlet 101 after being cleaned by the inner cleaning brush, and the inner cleaning brush rotates 90° counterclockwise to reset; and the degree of dirtiness and blockage of the second filter segment L2 is detected, and the transmittance M1 ≤ 70%. If the transmittance is qualified, it runs normally. If not qualified, the drum drives the annular filter screen 300 to run 2L distance clockwise, and the second filter segment L2 runs into the outer dust removal track segment 2021, as shown. Figure 1-Figure 3 As shown, the external cleaning brush in the external cleaning component 502 rotates 90° clockwise, and the drum drives the annular filter 300 to run L distance counterclockwise. The second filter segment L2 is cleaned by the external cleaning brush. At this time, the inner and outer surfaces of the second filter segment L2 are cleaned once, and the external cleaning brush rotates 90° counterclockwise to complete the resetting of the external cleaning brush bristles; the transmittance of the second filter segment L2 is detected again, and the transmittance M1 of the second filter segment L2 is ≤70%. If the transmittance is qualified, it runs normally. If it is unqualified, the user is prompted to deeply clean the filter component.

[0075] Of course, logical control can also be added. The outer cleaning brush cleans the outer surface of the filter. The filter runs counterclockwise for 4L, and the outer surfaces of both filter sections are cleaned. Then the inner cleaning brush cleans the inner surface of the filter. The filter runs clockwise for 4L, and the inner surfaces of both filter sections are cleaned. The inner and outer surfaces of the filter assembly are cleaned once.

[0076] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the filter section 301 of the annular filter screen 300 has an outer mesh surface and an inner mesh surface;

[0077] The cleaning assembly 500 includes an outer cleaning assembly 501 and an inner cleaning assembly 502;

[0078] The external cleaning component 501 is used to clean the external mesh surface of the filter section 301 , and the internal cleaning component 502 is used to clean the internal mesh surface of the filter section 301 .

[0079] That is, in the embodiment of the present application, by reasonably controlling the forward and reverse rotation of the annular filter 300, double-layer cleaning of the inner and outer surfaces of the filter segment 301 in the annular filter 300 can be achieved, thereby improving the cleaning effect of the filter while increasing the air intake of the air conditioner.

[0080] Further, in some possible implementations, the cleaning assembly 500 is disposed at a position of the dust removal track section 202 that avoids the air inlet 101;

[0081] The external cleaning component 501 of the cleaning component 500 is arranged between the external dust removal track segment 2021 and the outer side of the body 100, and is used for cleaning the outer mesh surface of the filter segment 301 moved into the external dust removal track segment 2021; the internal cleaning component 502 of the cleaning component 500 is arranged between the external dust removal track segment 2021 and the internal dust removal track segment 2022, and is used for cleaning the inner mesh surface of the filter segment 301 moved into the external dust removal track segment 2021, and / or cleaning the inner mesh surface of the filter segment 301 moved into the internal dust removal track segment 2022.

[0082] Preferably, the external cleaning assembly 501 includes an external cleaning brush that is rotatably arranged, and the internal cleaning assembly 502 includes an external cleaning brush that is rotatably arranged;

[0083] The inner cleaning brush and the outer cleaning brush both have a cleaning position in contact with the filter segment 301 and a avoiding position avoiding the filter segment 301 when rotating.

[0084] Furthermore, in some possible implementations, the air conditioner indoor unit further includes:

[0085] The heat exchange assembly 700 is disposed inside the body 100, a top space is defined between the top of the heat exchange assembly 700 and the air inlet 101, and a front space is defined between the front of the heat exchange assembly 700 and the front of the body 100;

[0086] The air inlet track section 201 is located in the top space, and the dust removal track section 202 is located in the front space.

[0087] In the embodiment of the present application, the air inlet track section 201 of the annular filter track 200 is arranged in the top space and the dust removal track section 202 is arranged in the front space. The surplus space formed between the heat exchange assembly 700 and the machine body 100 when the heat exchange assembly 700 is installed in the machine body 100 is fully utilized, thereby realizing the installation of the annular filter track 200 and the annular filter 300 without affecting the size of the whole machine.

[0088] Further, in some possible implementations, such as Figure 1-Figure 3 As shown, the driving assembly 400 includes a drum that can be driven to rotate, and the drum is meshed with the annular filter screen 300 at both ends in the length direction thereof, so as to be able to drive the annular filter screen 300 to move in the annular filter screen track 200 when the drum rotates;

[0089] The drum is rotated at the connection position between the outer air inlet track section 2011 and the outer dust removal track section 2021.

[0090] That is, the drum in the embodiment of the present application serves as a part of the annular filter track 200 , and since the drum is arranged at the connecting position between the external air inlet track section 2011 and the external dust removal track section 2021 , the installation of the drum will not affect the air intake of the air inlet 101 .

[0091] Further, in some possible implementations, such as Figure 2 As shown, the air conditioner indoor unit also includes:

[0092] The detection device 800 includes an external detection device 801 and an internal detection device 802. The external detection device 801 is used to detect the filter segment 301 moved to the outer air inlet track segment 2011, and output a parameter value representing the dirtiness and blockage of the filter segment 301. The internal detection device 802 is used to detect the filter segment 301 moved to the inner air inlet track segment 2012, and output a parameter value representing the dirtiness and blockage of the filter segment 301.

[0093] Preferably, both the external detection device 801 and the internal detection device 802 are light transmittance sensors with a light transmitter at one end and a light receiver at the other end.

[0094] Furthermore, the second aspect of the embodiment of the present application also provides an air conditioner, which includes the air conditioner indoor unit provided by the first aspect of the embodiment of the present application.
