Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Technology

[0002] Conventional air conditioners primarily remove dust by using air filters located near the air inlet to trap dust. However, excessive dust accumulation on these filters can have several negative consequences. For example, excessive dust can clog the filter mesh, hindering ventilation, affecting cooling and heating efficiency, significantly reducing air conditioning capacity, and increasing operating costs. Furthermore, some dust on the filter may re-enter the indoor air with the circulating airflow, impacting indoor air quality and contradicting the air conditioner's health-related functions. Therefore, how to clean the dust from air conditioner filters has become a common concern for both users and air conditioner manufacturers.

[0003] Therefore, after a period of use, the indoor unit filter and air intake baffle of the air conditioner need to be cleaned. In the existing technology, the cleaning methods of air conditioners include manual cleaning, which is time-consuming and labor-intensive.

[0054] Background Introduction

[0055] Conventional air conditioners primarily remove dust by using air filters located near the air inlet to trap dust. However, excessive dust accumulation on these filters can have several negative consequences. For example, excessive dust can clog the filter mesh, hindering ventilation, affecting cooling and heating efficiency, significantly reducing air conditioning capacity, and increasing operating costs. Furthermore, some dust on the filter may re-enter the indoor air with the circulating airflow, impacting indoor air quality and contradicting the air conditioner's health-related functions. Therefore, how to clean the dust from air conditioner filters has become a common concern for both users and air conditioner manufacturers.

[0056] Therefore, after a period of use, the indoor unit filter and air intake baffle of the air conditioner need to be cleaned. In the existing technology, the cleaning methods of air conditioners include manual cleaning, which is time-consuming and labor-intensive. It requires disassembling the various parts of the air conditioner for cleaning, and then reassembling the various parts after cleaning, which is quite cumbersome.

[0057] Based on this, such as Figures 1-4 As shown, the first aspect of this application provides a wall-mounted air conditioner indoor unit, including:

[0058] The body 100 has an air inlet 101 on its top.

[0059] The filter assembly includes an annular filter track 200 disposed inside the body and an annular filter 300 that can move 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] The drive 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 track 200 includes an air inlet track section 201 corresponding to the air inlet. The air inlet track section 201 includes an outer air inlet track section 2011 located close to the air inlet 101 and an inner air inlet track section 2012 located away from the air inlet 101. When one of the outer air inlet track section 2011 and the inner air inlet track section 2012 corresponds to the filter section 301 of the annular filter 300, the other corresponds to the hollow section 302 of the annular filter 300.

[0062] In this embodiment, an annular filter track and an annular filter that can move within the track are provided within the machine body. Related drive and cleaning components are also included. This allows the annular filter to be cleaned by the cleaning components as it moves within the track. Furthermore, the annular filter in this embodiment includes a perforated filter section and a hollow section without perforations. When one of the outer and inner air inlet track sections corresponds to the air inlet, a filter section is provided, and the other has a hollow section. This ensures effective filtration of the airflow into the inlet while avoiding the presence of filter sections in both the outer and inner air inlet track sections, which would affect the airflow volume.

[0063] Furthermore, in some possible implementations, such as Figure 4 As shown, the annular filter 300 has multiple filter sections 301 and multiple hollow sections 302, which are arranged alternately in the length direction of the annular filter 300.

[0064] The lengths of the filter section 301 and the hollow section 302 are designed to satisfy the following condition: when one of the external air inlet track section 2011 and the internal air inlet track section 2012 corresponds to the filter section 301, the other corresponds to the hollow section 302.

[0065] In this embodiment, the annular filter 300 is provided with multiple filter sections 301 and multiple hollow sections 302. The lengths of the filter sections 301 and hollow sections 302 are designed such that when one of the outer air inlet track section 2011 and the inner air inlet track section 2012 corresponds to a filter section 301, the other corresponds to a hollow section 302. This ensures that there is always a filter section 301 at the corresponding air inlet 101 to filter the airflow at the air inlet 101. Specifically, as shown... Figures 1-3 As shown, when the filter section 301 in the external air inlet track section 2011 is clogged and needs cleaning, the annular filter screen 300 can be driven to move clockwise. At this time, the filter section 301 in the external air inlet track section 2011 moves to a position that avoids the air inlet 101, and the filter section 301 in the position that avoids the air inlet 101 moves to the inner air inlet track section 2012 corresponding to the air inlet 101. That is, when cleaning the annular filter screen, there is always a filter section 301 at the position corresponding to the air inlet 101 to filter the airflow, so that the indoor unit of the air conditioner does not need to be stopped when cleaning the filter screen.

[0066] Furthermore, in some possible embodiments, the annular filter track 200 also includes a dust removal track section 202 that avoids the air inlet 101 and extends along the vertical direction of the body 100. The dust removal track section 202 includes an outer dust removal track section 2021 that is located close to the outside of the body 100 and an inner dust removal track section 2022 that is located away from the outside of the body 100. The outer air inlet track section 2011, the outer dust removal track section 2021, the inner dust removal track section 2022 and the inner air inlet track section 2012 are sequentially connected together to form the annular filter track 200.

[0067] The cleaning component 500 is used to clean the filter section 301 when the filter section 301 of the annular filter 300 moves into the dust removal track section 202. The air conditioner indoor unit also includes a dust collection component 600 located at the bottom of the dust removal track section 202. The dust collection component 600 is used to collect the lint that falls down when the cleaning component 500 cleans the filter section 301.

[0068] In this embodiment, the annular filter track 200 is configured as an air inlet track section 201 corresponding to the air inlet 101 and a dust removal track section 202 that avoids the air inlet 101. 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 that avoids the air inlet 101 and be cleaned by the cleaning component 500. The cleaned capillaries can fall directly into the dust collection component 600 at the bottom under the action of gravity, thereby realizing the collection of dust and hair.

[0069] Preferably, the dust collection assembly 600 is a dust collection box disposed at the bottom of the dust collection track section 201 and having an opening at the top.

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

[0071] The multiple filter sections 301 and multiple hollow sections 302 of the annular filter screen 300 have the same length, which is equal to the length L of the external air inlet track section 2011.

[0072] Preferred, such as Figure 4 As shown, the annular filter 300 includes two filter sections 301 and two hollow sections.

[0073] In this embodiment, the annular filter 300 is divided into four equal segments, including a first filter segment L1, a second filter segment L2, a first hollow segment L3, and a second hollow segment L4. That is, one filter segment, one hollow segment, one filter segment, and one hollow segment. A single drive assembly (preferably a roller) drives the annular filter 300, allowing the two filter segments 301 of the annular filter 300 to be used alternately during the self-cleaning and dust removal process. After startup, the air conditioner detects the current degree of filter clogging. If the clogging is acceptable, the filter does not need to be rotated and can be used directly. If the clogging is unacceptable, the filter assembly runs a certain distance to clean the filter before startup, resulting in high cleaning efficiency. Through logic control, the filter can be quickly replaced or thoroughly cleaned for a more complete cleaning.

[0074] Specifically, the operation control logic is as follows: When the air conditioner is turned on, it is assumed that there is a first filter section L1 in the external air inlet track section 2011. The degree of dirt and clogging of the first filter section L1 is judged, and the light transmittance M1 is ≤70% {where the light transmittance reaches 70% or more, it is usable}. If the light transmittance is qualified, it operates normally; if it is not qualified, such as... Figures 1-3As shown, the inner cleaning brush in the inner cleaning assembly 502 rotates 90° clockwise, contacts the second filter section L2, and the roller drives the annular filter screen clockwise a distance L. The first filter section L1 moves into the outer dust removal track section 2021. After being cleaned by the inner cleaning brush, the second filter section L2 moves into the inner air inlet track section 2012 of the corresponding air inlet 101. The inner cleaning brush then rotates 90° counterclockwise to reset. The light transmittance M1 of the second filter section L2 is checked for dirt accumulation. If the light transmittance is within 70%, normal operation is maintained. If not, the roller drives the annular filter screen 300 clockwise a distance of 2L, and the second filter section L2 moves into the outer dust removal track section 2021. Figures 1-3 As shown, the external cleaning brush in the external cleaning assembly 502 rotates 90° clockwise, and the roller drives the annular filter screen 300 to run counterclockwise a distance L. The second filter section L2 is cleaned by the external cleaning brush. At this time, both the inner and outer surfaces of the second filter section L2 are cleaned once. The external cleaning brush rotates 90° counterclockwise to complete the reset of the external cleaning brush bristles. The light transmittance of the second filter section L2 is checked again. If the light transmittance M1 of the second filter section L2 is ≤70%, the system will operate normally. If it is not qualified, the user will be prompted to perform a deep cleaning of the filter screen assembly.

[0075] Of course, logic control can also be added. The outer cleaning brush cleans the outer surface of the filter screen. The filter screen rotates counterclockwise for 4L per revolution, and both outer surfaces of the filter screen are cleaned. Then the inner cleaning brush cleans the inner surface of the filter screen. The filter screen rotates clockwise for 4L per revolution, and both inner surfaces of the filter screen are cleaned. The filter screen assembly is cleaned both inside and out.

[0076] Furthermore, in some possible implementations, such as Figures 1-3 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 component 500 includes an external cleaning component 501 and an internal cleaning component 502;

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

[0079] In this embodiment of the application, by reasonably controlling the forward and reverse rotation of the annular filter 300, it is possible to achieve double-layer cleaning of the inner and outer surfaces of the filter section 301 in the annular filter 300, thereby improving the cleaning effect of the filter while increasing the air intake of the air conditioner.

[0080] Furthermore, in some possible implementations, the cleaning component 500 is positioned at the dust removal track section 202 that avoids the air inlet 101;

[0081] The outer cleaning component 501 of the cleaning component 500 is disposed between the outer dust removal track section 2021 and the outer side of the body 100, and is used to clean the outer mesh surface of the filter section 301 that moves into the outer dust removal track section 2021. The inner cleaning component 502 of the cleaning component 500 is disposed between the outer dust removal track section 2021 and the inner dust removal track section 2022, and is used to clean the inner mesh surface of the filter section 301 that moves into the outer dust removal track section 2021, and / or clean the inner mesh surface of the filter section 301 that moves into the inner dust removal track section 2022.

[0082] Preferably, the external cleaning component 501 includes a rotatably configured external cleaning brush, and the internal cleaning component 502 includes a rotatably configured internal cleaning brush;

[0083] Both the inner and outer cleaning brushes have cleaning positions that contact the filter section 301 and avoidance positions that avoid the filter section 301 when they rotate.

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

[0085] Heat exchange component 700 is located inside the body 100. A top space is defined between the top of the heat exchange component 700 and the air inlet 101, and a front space is defined between the front of the heat exchange component 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 this embodiment, by setting the air inlet track section 201 of the annular filter track 200 in the top space and setting the dust removal track section 202 in the front space, the excess space formed between the heat exchange component 700 and the body 100 when the heat exchange component 700 is installed in the body 100 is fully utilized, thereby realizing the installation of the annular filter track 200 and the annular filter 300 without affecting the overall size of the machine.

[0088] Furthermore, in some possible implementations, such as Figures 1-3 As shown, the drive assembly 400 includes a roller that can be driven to rotate, with both ends of the roller engaging with the annular filter screen 300 in the longitudinal direction, so as to drive the annular filter screen 300 to move in the annular filter screen track 200 when it rotates.

[0089] The rotating drum is located at the junction of the external air inlet track section 2011 and the external dust removal track section 2021.

[0090] In this embodiment, the roller is part of the annular filter track 200. Since the roller is located at the junction of the external air inlet track section 2011 and the external dust removal track section 2021, the installation of the roller will not affect the air intake of the air inlet 101.

[0091] Furthermore, in some possible implementations, such as Figure 2 As shown, the indoor unit of the air conditioner 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 section 301 that moves to the external air inlet track section 2011 and output parameter values ​​characterizing the dirt and clogging status of the filter section 301. The internal detection device 802 is used to detect the filter section 301 that moves to the internal air inlet track section 2012 and output parameter values ​​characterizing the dirt and clogging status of the filter section 301.

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

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