Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] It should be noted that for the directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0042] The present invention provides an indoor air conditioner and an air conditioner. The indoor air conditioner can be used alone, or the indoor air conditioner can be used in combination with the air conditioner. Specifically, the air conditioner can be a wall-mounted machine, an indoor air conditioner or a mobile air conditioner, etc.

[0043] Please refer to Figures 1 to 3 , the indoor air conditioner 10 provided in this embodiment includes a housing 100, a fan component 200, a purification device 300 and a cover 400. The housing 100 is provided with a first air inlet 111, a second air inlet 112 and an air outlet 113. A heat exchange air duct 110 is formed in the housing 100. The heat exchange air duct 110 communicates with the first air inlet 111, the second air inlet 112 and the air outlet 113. The fan component 200 is arranged in the heat exchange air duct 110 so that air flows into the heat exchange air duct 110 from the first air inlet 111 and / or the second air inlet 112 and flows out from the air outlet 113. The purification device 300 is arranged at the second air inlet 112. In this embodiment, please refer to Figure 1, the indoor air conditioner 10 is a wall-mounted indoor air conditioner 10. The first air inlet 111 and the second air inlet 112 are both provided at the upper end of the housing 100, and the air outlet 113 is provided at the lower end of the housing 100. In other embodiments, the indoor air conditioner 10 may also be a floor-standing unit, the first air inlet 111 and the second air inlet 112 are provided at the lower end of the housing 100, and the air outlet 113 is provided at the upper end of the housing 100. Specifically, the installation positions of the first air inlet 111, the second air inlet 112, and the air outlet 113 can be arranged according to the shape of the housing 100 and the application scenario. The purification device 300 is used to filter impurities in the air flowing through the second air inlet 112. Specifically, it may include filters for filtering particulate matter, such as HEPA, HAF, IFD, etc., and may also include filters for filtering gaseous pollutants, such as activated carbon mesh, catalytic oxidation formaldehyde removal mesh, or VOC mesh, etc.

[0044] In this embodiment, please refer to Figure 3 and Figure 4 , a first air inlet 111 is further opened on the housing 100, and the cover body 400 is movably provided at the first air inlet 111 of the housing 100. The cover body 400 has a closed state for closing the first air inlet 111 and an open state for opening the first air inlet 111. When the air conditioner is working, it can select the enhanced purification mode or the enhanced heat exchange mode. In the enhanced purification mode, please refer to Figures 7 to 9 , the cover body 400 closes the first air inlet 111, and the air entering the heat exchange air duct 110 all flows out after being purified, and the air conditioner has better purification performance. However, in the case of the same air volume, the air resistance is large, so the cooling or heating is slower and the heat exchange effect is not good. In the enhanced heat exchange mode, please refer to Figure 5 and Figure 6 , the cover body 400 opens the first air inlet 111, and the air flows into the heat exchange air duct 110 from the first air inlet 111 and the second air inlet 112. Therefore, at the same air volume, the heat exchange efficiency is higher and the cooling or heating effect is better. Those skilled in the art can understand that the air conditioner can switch between the enhanced purification mode and the enhanced heat exchange mode by itself, or can be switched between the two modes by the user according to needs. For example, within a certain period of time when the air conditioner starts to work, it adopts the enhanced heat exchange mode, controls the cover body 400 to open the first air inlet 111, the air inlet area is large, the air resistance is small, and the heat exchange efficiency is improved, so that the air conditioner can quickly cool or heat. After a period of time in the enhanced heat exchange mode, it is controlled to enter the enhanced purification mode, and the cover body 400 is controlled to close the first air inlet 111, and the air can only flow into the heat exchange air duct 110 from the second air inlet 112, and all the inflowing air is purified by the purification device 300 to ensure the air quality in the room and the purification effect is better.

[0045] In one embodiment, the second air inlet 112 and the first air inlet 111 are separately provided. In another embodiment, the quantity air inlet and the second air inlet 112 can also be connected and integrated. Specifically, a large air inlet is formed on the housing 100 of the air conditioner indoor unit 10. Part of the area belongs to the second air inlet 112, and a purification device 300 is correspondingly provided. Another part of the area of the large air inlet belongs to the first air inlet 111. The cover 400 is movably arranged at the first air inlet 111 to partially cover the large air inlet in the closed state. Specifically, the cover 400 covers the part of the large air inlet that belongs to the first air inlet 111 in the closed state, so as to achieve the purpose of adjusting the switching between the enhanced heat exchange mode and the enhanced heat exchange mode of the air conditioner according to needs.

[0046] In this embodiment, please refer to Figure 2 , the cover 400 is provided with one, which is used to close the first air inlet 111 in the enhanced purification mode. In other embodiments, there can also be multiple covers 400, and each cover 400 is respectively movably arranged at the first air inlet 111 of the housing 100. Thus, the first air inlet 111 can be covered more flexibly. In one embodiment, according to the need to increase the air intake volume, multiple covers 400 can also be controlled to partially close the second air inlet 112 or completely close the second air inlet 112, so that the air conditioner has a multi-stage adjustment mode, and thus the opening area of the first air inlet 111 can be controlled according to needs.

[0047] There are various ways to drive the cover 400 to open or close the first air inlet 111. For example, the position of the cover 400 can be manually adjusted to open or close the first air inlet 111. In this embodiment, the air conditioner indoor unit 10 further includes a driving device, and the driving device is drivingly connected to the cover 400 to drive the cover 400 to open or close the first air inlet 111, so as to more conveniently adjust the position of the cover 400.

[0048] There are also various installation methods for the cover 400. In this embodiment, please refer to Figure 3 and Figure 4 , the cover 400 is rotatably installed on the housing 100 to have a rotating part 401 and a movable end 402 that can rotate relative to the rotating part 401. The driving device drives the movable end 402 of the cover 400 to rotate around the rotating part 401 to rotate and open or close the first air inlet 111. For example, the driving device can be drivingly connected to the rotating shaft of the cover 400 and drive the rotating shaft to rotate, thereby driving the movable end 402 of the cover 400 to rotate. In other embodiments, the cover 400 can also be slidably installed on the first air inlet 111, or rollingly installed on the first air inlet 111, and the driving device is drivingly connected to the cover 400 in a manner adapted to the installation method of the cover 400, so as to drive the cover 400 to open and close automatically.

[0049] Based on the previous embodiment, please refer to Figure 4 , the rotating part 401 is arranged in the middle of the cover body 400, and the movable ends 402 are correspondingly arranged at both ends of the cover body 400. In this way, the moving stroke of the cover body 400 to close or open the first air inlet 111 can be shortened, the structure is more stable and not easily damaged.

[0050] Based on the above embodiment, please refer to Figure 4 , a limiting protrusion 500 is arranged at the first air inlet 111, and the limiting protrusion 500 is arranged corresponding to the movable end 402 of the cover body 400 to limit the moving stroke of the cover body 400. In this embodiment, when the cover body 400 rotates to the closed position, the limiting protrusion 500 abuts against the movable end 402 of the cover body 400, so that the cover body 400 is limited in the closed position.

[0051] Furthermore, a first limiting inclined surface 501 and a second limiting inclined surface 502 are respectively arranged on the limiting protrusion 500 and the movable end 402 of the cover body 400. When the cover body 400 closes the first air inlet 111, the first limiting inclined surface 501 and the second limiting inclined surface 502 are lapped and fitted. Thus, good sealing performance is achieved, the gap between the cover body 400 and the housing 100 is reduced, and the cover body 400 better closes the first air inlet 111. It is ensured that in the enhanced purification mode, air flows into the heat exchange air duct 110 from the second air inlet 112 and is fully purified by the purification device 300, improving the indoor air quality.

[0052] In one embodiment, please refer to Figure 3 , the air conditioner indoor unit 10 further includes a primary filter 600, and the primary filter 600 is arranged in the housing 100 and at least covers the second air inlet 112. The primary filter 600 can be arranged in front of the purification device 300 or behind the purification device 300, and cooperates with the purification device 300 to further filter impurities in the air.

[0053] Based on the previous embodiment, the primary filter 600 can also cover the first air inlet 111 and the second air inlet 112. In the enhanced heat exchange mode, the air entering the heat exchange air duct 110 through the first air inlet 111 is at least purified by the primary filter 600 to achieve a preliminary purification effect. At the same time, compared with the enhanced purification mode, the air intake efficiency is still increased, and better cooling or heating effects are obtained.

[0054] The purification device 300 may specifically include a particulate filter and / or a gaseous pollutant filter. The particulate filter is used to filter out tiny particles in the air, such as HEPA, HAF, IFD, etc., while the gaseous pollutant filter is used to filter out harmful gases in the air (such as formaldehyde, etc.), such as an activated carbon mesh, a catalytic oxidation formaldehyde removal mesh, or a VOC mesh, etc. To achieve a better purification effect, the purification device 300 may specifically include both a particulate filter and a gaseous pollutant filter. The filtering device further includes a beneficial component generating device, which may include, for example, an oxygen generating device or a negative ion generator, so as to further make the air flowing out of the heat exchange air duct 110 rich in beneficial substances and improve the indoor air quality.

[0055] The present invention also provides an air conditioner, which includes an outdoor unit of the air conditioner and an indoor unit 10 of the air conditioner. The indoor unit 10 of the air conditioner is connected to the outdoor unit of the air conditioner through a refrigerant pipe. For the specific structure of the indoor unit 10 of the air conditioner, please refer to the above embodiments. Since the air conditioner includes the indoor unit 10 of the air conditioner, it has all the effects brought by the indoor unit 10 of the air conditioner, which will not be elaborated here.
