[0026] As the air conditioner is used for a longer time, more dust will accumulate on the filter of the air conditioner. In order to prevent the dust from clogging the filter and affecting the heat exchange effect of the air conditioner, most air conditioners are currently equipped with a filter cleaning device to clean the filter. Although water-washed filters can wash away the dust on the filters with water to a certain extent, water-washed filters require manual water addition, which is inconvenient to operate; or a water pump is required to collect condensed water for cleaning. The collection of condensed water is affected by the season, and a filter needs to be set to filter the condensed water, which causes noise and cost issues.

[0027] To this end, the present invention proposes an air conditioner indoor unit, which aims to provide a solution that relies on a fresh air system to discharge dust from filter cleaning to the outdoors, thereby achieving a dust removal solution without relying on water and without causing the problem of dust accumulation.

[0028] In one embodiment of the present invention, Figures 1 to 8As shown, the air conditioner indoor unit 100 includes a filter element 110, a filter bracket 120, a cleaning box 200, a cleaning component 400 and a fresh air system 500. The filter bracket 120 places the filter element 110; the cleaning box 200 is arranged at one end of the filter bracket 120, and a movable channel 300 is provided in the cleaning box 200 and the filter bracket 120; the cleaning component 400 is used to clean the filter element 110; the fresh air system 500 has an exhaust channel 520, and the cleaning box 200 is provided with a dust exhaust port 220 which is in communication with the exhaust channel 520.

[0029] In one embodiment, the air-conditioning indoor unit 100 is a wall-mounted unit, which is installed on the wall through a back panel. The supporting member is connected to the shell of the air-conditioning indoor unit 100, and is located at the air inlet above the air-conditioning indoor unit 100. The supporting member can also be regarded as a cover plate of the air inlet. A displacement channel is formed between the supporting member and the shell of the air-conditioning indoor unit 100, that is, after the filter element 110 is installed on the supporting member, it can move in the displacement channel, such as the two channels between three parallel partitions. The cooperation between the filter element 110 and the cleaning component 400 can refer to the existing method. The cleaning box 200 is located on one side of the air-conditioning indoor unit 100, so that the filter element 110 is moved from the carrier to the cleaning box 200 for dust removal under the drive of the cleaning component 400, and then returns to the carrier after cleaning; the cleaned dust will fall into the cleaning box 200. In the traditional solution, in order to avoid the problem of dust accumulation, the filter screen is washed with water, and water flows into the cleaning box 200, and finally the waste water is discharged; in this solution, with the help of the exhaust function of the fresh air system 500, the cleaning box 200 is provided with a dust exhaust port 220 that is connected to the exhaust channel 520, so that the dust in the cleaning box 200 will be carried away by the airflow from the exhaust channel 520 and discharged to the outside, so as to achieve the purpose of dust removal without causing the problem of dust accumulation; there is also no need to manually take out the cleaning box 200 to dump the dust.

[0030] The filter element 110 is used to purify the air inhaled and exhausted by the air conditioner, and can filter particulate impurities in the air. The fresh air system 500 refers to a function in the air conditioning system, which can introduce fresh air and exhaust indoor dirty air to maintain indoor air quality. The fresh air system 500 is usually composed of the following parts: Fresh air fan: The fresh air fan is the core component of the fresh air system 500, which is responsible for introducing fresh air and exhausting indoor dirty air. The fresh air fan usually has an adjustable air volume and wind speed, and the air flow rate can be adjusted as needed. Filter: The filter in the fresh air system 500 can filter out pollutants such as particulate matter, dust and bacteria in the air to provide cleaner air. Heat exchanger: The heat exchanger in the fresh air system 500 can use the heat of the exhausted indoor dirty air to preheat the incoming fresh air, thereby improving energy utilization efficiency. Duct system: The fresh air system 500 transports fresh air to various areas of the room through the duct, and exhausts the indoor dirty air to the outside. The main function of the fresh air system 500 is to provide fresh air, improve indoor air quality, reduce the accumulation of indoor pollutants, and increase indoor comfort. At the same time, the fresh air system 500 can also save energy and improve the efficiency of the air conditioning system.

[0031] In other embodiments, the air-conditioning indoor unit 100 is a vertical air-conditioner or the like.

[0032] An indoor unit with a fresh air function is a device that can improve indoor air quality through fresh air provided by the outside world. These devices usually have filtering and purification functions, which can effectively remove pollutants and harmful substances in the air. At the same time, they can also provide constant humidity control and temperature adjustment to ensure the comfort of the indoor environment.

[0033] In order to prevent dust from affecting the fresh air function of the fresh air system 500 , a valve assembly 580 is provided in the cleaning box 200 , and the valve assembly 580 is used to open / close the dust exhaust port 220 .

[0034] Reference Figure 3 In one embodiment, the valve assembly 580 includes a valve motor 581 and a valve body 582 drivingly connected to the valve motor 581, and the valve body 582 can cover or reveal the dust exhaust port 220. The valve body 582 can be a shielding plate, and when the fresh air system 500 is in a mode other than the dust exhaust mode, the shielding plate shields the dust exhaust port 220, so that dust in the cleaning box 200 will not be taken away in other modes.

[0035] Reference Figure 8 In another embodiment, the valve assembly 580 includes a valve motor 581 and a valve body 582 drivingly connected to the valve motor 581 . Driven by the valve motor 581 , the valve body 582 rotates in the cleaning box 200 .

[0036] In the above embodiment, in order to make the dust in a dust-raising state, a brush head 583 is provided at the end of the cavity wall of the valve body 582 close to the dust exhaust port 220.

[0037] Reference Figures 1 to 3 In order to ensure the cleaning effect, a guide structure 210 is provided in the cleaning box 200 , and the guide structure 210 is used to guide the dust to the dust exhaust port 220 .

[0038] Specifically, in one embodiment, the guide structure 210 is a bottom wall of the cleaning box 200 that is curved in the direction from the dust outlet 220 to the cleaning assembly 400 to ensure that dust falls near the dust outlet 220 to be carried away and discharged.

[0039] In another embodiment, the guide structure 210 is inclined at the bottom of the cleaning chamber toward the dust outlet 220 , and the accumulated dust will gather at the dust outlet 220 under the action of gravity and wind suction, so as to be discharged from the exhaust channel 520 .

[0040] The valve body 582 rotates in the cleaning box 200, and when dust discharge is required, the dust removal mode is entered. At this time, the fresh air system 500 is in an exhaust working state. At this time, the valve and the brush head 583 are in a rotating state, thereby continuously sprinkling dust at the bottom of the cleaning box 200 into the exhaust passage 520. After being swept by the brush head 583, the dust can be turned into fine dust floating on the exhaust passage 520, so that through the exhaust function of the fresh air, the dust in the cleaning box 200 can be more easily sent to the outside through the fresh air duct.

[0041] Reference Figures 4 to 6 In order to avoid dust interference with the fresh air system 500, this solution makes improvements to the fresh air system 500.

[0042] In one embodiment, the fresh air system 500 includes: a fresh air housing 510, an exhaust passage 520, and an indoor air inlet 521, a fresh air outlet 522, and an air inlet and outlet 523 connected to the exhaust passage 520, and a fresh air impeller 530 is arranged in the exhaust passage 520 to introduce outdoor air from the fresh air outlet 522; or to lead indoor air out from the air inlet and outlet 523; and The valve plate 550 is disposed in the exhaust passage 520 and can close the indoor air inlet 521 or the fresh air outlet 522 .

[0043] Fresh air outlets 522 and air inlets and outlets 523 are provided at both ends of the exhaust channel 520. The shell is provided with an indoor air inlet 521 on one side of the fresh air outlet 522. The indoor air inlet 521 is connected to the exhaust channel 520 and shares the common air inlet and outlet 523. The valve plate 550 can be driven by a motor to rotate to close the indoor air inlet 521 or the fresh air outlet 522; it can also be closed by sliding.

[0044] Specifically, when the valve plate 550 closes the indoor air inlet 521, the outside air is sucked in from the air inlet and outlet 523 and discharged from the fresh air outlet 522. At this time, the dust exhaust port 220 is closed by the valve assembly 580, and the dust in the cleaning box 200 will not be brought in by the fresh air.

[0045] When the valve plate 550 closes the fresh air outlet 522, the indoor air enters from the indoor air inlet 521, is driven by the wind wheel of the exhaust duct 520, and is then discharged from the air inlet and outlet 523. At this time, the fresh air system 500 is in the dust exhaust mode, which is also the exhaust mode. At this time, the valve assembly 580 of the dust exhaust port 220 is opened, and the dust in the dust exhaust port 220 is carried away and discharged.

[0046] Reference Figure 7 and Figure 8 In the previous scheme, because a common air inlet and exhaust vent is used, although the structure is simpler, there is a problem of dust residue. In another embodiment, the fresh air system 500 includes a fresh air shell 510, and the fresh air shell 510 is formed with a connected fresh air channel and an exhaust channel 520, the fresh air channel is provided with a fresh air wheel 530, and the exhaust channel 520 is provided with an exhaust wheel 540. The fresh air channel has an air outlet 524 connected to the exhaust channel 520, and a movable valve is provided in the exhaust channel 520, and the valve can cover the air outlet 524 or cover the outlet of the exhaust channel 520.

[0047] In this solution, the fresh air system 500 has two volutes and two wind wheel structures, and the two parts of the structure work independently. The two parts are divided into a fresh air module and a dust removal module according to their functions. In the fresh air module, the fresh air volute and the fresh air wind wheel 530 are used in the fresh air working mode, and in the dust removal module, the dust removal volute and the dust removal wind wheel are used in the dust removal mode. The fresh air volute has a connected air port 524 at the end of the exhaust passage 520, and a valve for shielding the exhaust passage 520 or the air port 524 is provided in the dust removal volute. The cleaning box 200 has a dust removal port connected to the exhaust passage 520. The valve assembly 580 is arranged in the cleaning box 200, that is, the valve assembly 580 includes a valve motor 581 and a valve body 582 connected to the valve motor 581. Under the drive of the valve motor 581, the valve body 582 rotates in the cleaning box.

[0048] Specifically, the fresh air system 500 includes a fresh air shell 510, in which an air outlet 524 of a fresh air channel and an exhaust channel 520 connected to each other is formed, the fresh air channel is provided with a fresh air wheel 530, the exhaust air channel 520 is provided with an exhaust wheel 540, the outlet of the exhaust air channel 520 is provided with a first valve 560, the first valve 560 can cover the outlet or the air outlet 524, and the entrance of the fresh air channel is provided with a second valve 570 that can cover or reveal the entrance.

[0049] When the fresh air is running, outdoor air enters from the exhaust duct 520, but because the valve of the dust removal volute blocks the exhaust duct 520, the air passes through the fresh air filter from the side air outlet 524 and then enters the fresh air volute, and under the action of the fresh air impeller 530, the fresh air is sent out.

[0050] In this solution, the valve assembly 580 can be set in the cleaning box 200; or it can be set in the cleaning box 200. When in the cleaning box 200, it mainly plays the role of dust removal. The blocking of the first valve 560 can close the outlet of the exhaust channel 520, and the air outlet 524 is connected to the fresh air channel, which can ensure that dust exhaust and fresh air do not interfere with each other.

[0051] When the dust removal mode is in progress, the valve switches to close the air port 524, and the exhaust channel is in an open state. The indoor air passes through the air inlet of the air conditioner and passes through the dust removal volute of the filter element 110. Under the action of the dust removal wind wheel, the dust in the cleaning box is lifted up and discharged through the exhaust channel 520. In this process, the valve assembly 580 is arranged in the cleaning box 200, and the dust is turned into fine dust floating on the exhaust channel 520, so that through the exhaust function of the dust removal volute, the dust in the cleaning box 200 is more easily sent to the outside through the fresh air duct. At this time, the dust removal outlet channel is unobstructed, so that the dust removal of the air conditioner filter is not restricted by seasons, and the dust on the filter can be automatically discharged to the outside without affecting the fresh air and its exhaust function.

[0052] Regarding cleaning of the filter element 110 .

[0053] The filter element 110 is driven by a driving assembly, and the driving assembly is configured as a roller assembly. The cleaning assembly 400 includes a brush assembly 410 and a dust scraping structure 420. The roller assembly is arranged in the movable channel 300 to drive the filter element 110 to move in the movable channel 300; the brush assembly 410 is arranged in the movable channel 300, located below the roller assembly, to clean the filter element 110; and the dust scraping structure 420 is arranged in the movable channel 300 to scrape off dust on the brush assembly 410.

[0054] Specifically, the carrier includes a first installation cavity and a second installation cavity for placing the filter member 110, the roller assembly is installed in the cleaning box 200, the roller assembly includes a roller member and a guide member arranged below the roller member, the roller member is engaged with the filter member 110, the guide member is used to guide the filter member 110, and the roller member drives the filter member 110 to move between the first installation cavity and the second installation cavity.

[0055] The roller member and the filter member 110 are meshed with each other, and gears are provided at the ends of the roller to mesh with the teeth on both sides of the filter member 110. The roller member and the brush assembly 410 can be driven by motors individually, or by a motor and a gear set.

[0056] After the roller member rotates, the filter member 110 is moved out of the first installation cavity and driven toward the brush assembly 410. After passing through the guide member, the filter member 110 changes direction and moves toward the second installation cavity. During this process, the brush assembly 410 located below the guide member rotates to clean the dust on the filter member 110, so that the dust is separated from the filter member 110. The cross-section of the guide member is C-shaped, which facilitates the smooth movement of the filter member 110.

[0057] During the process of the brush assembly 410 cleaning the filter element 110 , since fluff easily sticks to the brush assembly 410 and piles up to cover the brush and affect the cleaning effect, a dust scraping structure 420 is provided to scrape off the dust on the brush assembly 410 .

[0058] The dust scraping structure 420 may be disposed obliquely above the brush assembly 410 , or may be disposed below the brush assembly 410 .

[0059] Specifically, the dust scraping structure 420 is disposed in the cleaning box 200 and is located below the brush assembly 410 .

[0060] The scraping structure 420 is configured as a scraping member 421 , one end of which is connected to the wall of the cleaning box 200 , and the other end of which is close to the brush assembly 410 .

[0061] In order to ensure the cleaning effect, the end of the scraper 421 is provided with a bevel chamfer. In one embodiment, the scraper 421 and the cleaning box 200 are detachably connected; in another embodiment, the scraper 421 and the cleaning box 200 are integrated into one body, which is convenient for processing and production.

[0062] Specifically, the scraping members 421 include two, the two scraping members 421 are arranged facing each other, a dust outlet 422 is formed between the two scraping members 421, and the dust outlet 422 is located below the brush assembly 410. On the one hand, the provision of the two scraping members 421 can improve the cleaning effect, and on the other hand, when the filter member 110 is reset to the first installation cavity, the cleaning of the filter member 110 can also be ensured.

[0063] In one embodiment, the cross-sections of the two scraping members 421 are both inclined "I"; in another embodiment, the cross-sections of the scraping members 421 are Z-shaped, and a clearance opening can be provided in the gap between the scraping members 421 and the side walls of the cleaning box 200 to facilitate the dust at this position to fall into the bottom of the cleaning box 200.

[0064] Furthermore, a brush tooth structure 423 is provided on a side of the scraper 421 facing the brush assembly 410 .

[0065] The brush tooth structure 423 is a brush tooth like a "comb" arranged at the end of the scraper 421.
