[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Combine the following Figures 1 to 5 , describing the air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0030] According to an embodiment of the utility model, an air conditioner indoor unit 100 includes: a casing 10, a heat exchanger 20, a purification component 30, and a driving component 40. The casing 10 is provided with an air inlet 10a. The heat exchanger 20 is arranged in the casing 10. The driving component 40 is arranged on the casing 10. The purification component 30 is arranged in the casing 10 and is located between the air inlet 10a and the heat exchanger 20. The purification component 30 is connected to the driving component 40 and can be switched between a first position and a second position under the drive of the driving component 40. Among them, when the purification component 30 is in the first position, the purification component 30 covers the air inlet 10a, and when the purification component 30 is in the second position, the purification component 30 is away from the air inlet 10a and close to the heat exchanger 20.

[0031] In the above embodiment, the air inlet 10a is used for taking air into the housing 10 , and the air inlet 10a may include but is not limited to being arranged at one or more positions of the top, bottom, front, rear, left and right of the housing 10 .

[0032] The purification component 30 may refer to a component used to purify particulate matter, dust, bacteria and other microorganisms in the air, thereby improving the air quality. The purification component 30 may be, but is not limited to, a filter screen, a filter membrane, etc. Among them, when the purification component 30 is a filter screen, the filter screen may include, but is not limited to, a HEPA screen, a HAF screen, a manganese screen, a gel filter screen, etc.

[0033] “The driving member 40 is disposed on the casing 10” can be understood as that the driving member 40 can be disposed outside the casing 10, and the output end of the driving member 40 passes through the casing 10 and is connected to the purification member 30; or, the driving member 40 can also be disposed inside the casing 10, and the output end of the driving member 40 is connected to the purification member 30.

[0034] The driving member 40 can drive the purification member 30 to achieve position switching. Figure 1 and Figure 3 When the driving member 40 drives the purification member 30 to be in the first position, the purification member 30 covers the air inlet 10a. In this state, the air conditioner indoor unit 100 can be in the purification mode. When the air enters from the air inlet 10a, it will pass through the purification member 30 and achieve air purification. The required air intake volume in this process is relatively low, and the purification effect is relatively good. Figure 2 and Figure 4 When the driving member 40 drives the purification member 30 to be in the second position, the purification member 30 can be away from the air inlet 10a, reducing wind resistance, reducing air volume attenuation, and reducing the influence of the purification member 30 on the air intake volume. In this state, the air-conditioning indoor unit 100 can be in cooling or heating mode. This process can achieve a relatively large air intake volume, thereby enabling the air-conditioning indoor unit 100 to have better heating or cooling capacity. Moreover, since the purification member 30 is close to the heat exchanger 20, it can also play a certain purification role, making the air outlet of the air-conditioning indoor unit 100 healthier during heating or cooling.

[0035] In the above embodiment, the driving member 40 drives the purification member 30 to move in a manner including but not limited to horizontal movement, rotation, etc., and the specific structure of the driving member 40 is not limited in this embodiment.

[0036] It should be noted that the air-conditioning indoor unit 100 of the embodiment of the utility model can be but not limited to a wall-mounted unit, a cabinet unit, a window unit, etc., and no specific limitation is made here.

[0037] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, by setting a driving member 40 to drive the connection purification member 30, the purification member 30 can be driven to a first position covering the air inlet 10a, so that the air can be efficiently purified when passing through the air inlet 10a, so that the whole machine has a higher purification effect, and the purification member 30 can also be driven to a second position away from the air inlet 10a and close to the heat exchanger 20, which can reduce the wind resistance at the air inlet 10a, so that the air-conditioning indoor unit 100 has a larger air intake volume, which is beneficial to improving the heating or cooling capacity of the whole machine.

[0038] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, when the purification element 30 is arranged in the first position, it covers a portion of the air inlet 10a.

[0039] In this embodiment, the size of the purification component 30 is smaller than the size of the air inlet 10a, that is, the air inlet 10a can be divided into at least two areas, which are respectively recorded as a first area 101 and a second area 102. The purification component 30 is in the first position to cover the first area 101. In this way, when the air-conditioning indoor unit 100 needs to purify the air in the purification mode, the air at the location of the first area 101 is purified by the purification component 30. Compared with the first area 101, the second area 102 has smaller wind resistance and less air volume attenuation when taking in air, which is conducive to accelerating indoor air circulation.

[0040] It can be understood that the above scheme can better balance the air purification amount and the air intake amount. The air conditioner indoor unit 100 has a higher air intake amount while meeting the air purification requirements, thereby improving the working efficiency of the whole machine in the purification mode.

[0041] In some embodiments of the present invention, the shell wall of the casing 10 having the air inlet 10a is the first shell wall. When the purification element 30 is in the first position, the projection area of ​​the purification element 30 on the first shell wall is half of the area of ​​the air inlet 10a.

[0042] It can be understood that the casing 10 may include multiple casing walls, and the casing wall provided with the air inlet 10a is recorded as the first casing wall. When the purification component 30 is in the first position, the projection area of ​​the purification component 30 on the first casing wall is half of the area of ​​the air inlet 10a. In this way, the balance between the air purification amount and the air intake amount of the air conditioner indoor unit 100 in the purification mode can be better, and the whole machine can further have a better purification effect and higher working efficiency.

[0043] In some embodiments of the present invention, Figures 1 to 4 As shown, the casing 10 includes a connected top shell wall 11 and a front shell wall 12, the top shell wall 11 is provided with an air inlet 10a, and the air inlet 10a extends to the front shell wall 12; the heat exchanger 20 includes a first heat exchange part 21, the first heat exchange part 21 is inclined relative to the top shell wall 11, and one end of the first heat exchange part 21 is close to the top shell wall 11, and the other end is close to the front shell wall 12, wherein the purification element 30 is arranged in a space jointly defined by the top shell wall 11, the front shell wall 12 and the first heat exchange part 21.

[0044] In the above technical solution, the first heat exchange part 21 is inclined relative to the top shell wall 11, and one end of the first heat exchange part 21 is close to the top shell wall 11, so that the top shell wall 11, the front shell wall 12 and the first heat exchange part 21 can form a relatively ample space. By arranging the purification component 30 in the space, on the one hand, the space formed by the top shell wall 11, the front shell wall 12 and the first heat exchange part 21 can be fully utilized to improve the space utilization rate inside the air-conditioning indoor unit 100. On the other hand, it is convenient to arrange the purification component 30, and it is also easier to realize the position switching of the purification component 30.

[0045] Alternatively, if Figures 1 to 4 As shown, the top shell wall 11 and the front shell wall 12 are substantially perpendicular to each other. That is, the top shell wall 11 and the front shell wall 12 may be perpendicular to each other; the angle between the top shell wall 11 and the front shell wall 12 is close to 90 degrees, for example, the angle between the top shell wall 11 and the front shell wall 12 may be, but not limited to, 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, etc.

[0046] In the above solution, the top shell wall 11 and the front shell wall 12 are substantially perpendicular to each other, so that a relatively large space is formed between the top shell wall 11 , the front shell wall 12 and the first heat exchange part 21 , which facilitates the arrangement of the purification element 30 .

[0047] In some embodiments of the present invention, Figures 1 to 5As shown, the casing 10 also includes a rear casing wall 13, which is connected to the top casing wall 11; the heat exchanger 20 also includes a second heat exchange portion 22 and a third heat exchange portion 23, which are arranged at opposite ends of the first heat exchange portion 21, the second heat exchange portion 22 is close to the front casing wall 12, and the third heat exchange portion 23 is close to the rear casing wall 13.

[0048] It can be understood that in the above scheme, the heat exchanger 20 constitutes a three-section structure. For example, the heat exchanger 20 is C-shaped as a whole and is compactly arranged inside the casing 10. With this scheme, the internal structure of the air-conditioning indoor unit 100 is more compact, which is beneficial to reducing the volume of the whole machine and is beneficial to the miniaturization of the air-conditioning indoor unit 100.

[0049] In some embodiments of the present invention, Figures 1 to 4 As shown, the driving member 40 is a rotary driving member, which can drive the purification member 30 to rotate between the first position and the second position.

[0050] In the above solution, the rotary drive component may be, but is not limited to, a motor, a rotary cylinder, a rotary oil cylinder and the like.

[0051] By setting the driving member 40 as a rotating driving member and driving the purification member 30 to switch between the first position and the second position in a rotational manner, this driving method can be combined with the limited space inside the casing 10 to easily realize the position switching of the purification member 30, thereby improving the feasibility of the entire solution. In addition, this driving method has a relatively simple structure, high stability and reliability, and is conducive to extending the service life.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the driving member 40 is disposed close to an end of the first heat exchange portion 21 away from the front shell wall 12 , and close to the top shell wall 11 .

[0053] In this technical solution, since the driving member 40 is far away from the front shell wall 12, there is more space around the driving member 40 during the assembly stage and there are fewer obstacles, which is conducive to reducing the difficulty of assembling the driving member 40, improving the assembly efficiency and product yield of the whole machine, and also facilitating the inspection and maintenance of the driving member 40 during the inspection and maintenance stage.

[0054] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the driving member 40 is arranged near the corner of the front shell wall 12 and the top shell wall 11.

[0055] In this technical solution, since the driving member 40 is close to the corner position of the front shell wall 12 and the top shell wall 11, when the driving member 40 drives the purification member 30 to switch to the second position, the purification member 30 can be set close to the front shell wall 12. In this way, when the air-conditioning indoor unit 100 is heating or cooling, the purification member 30 will not be in the flow path of the incoming air flow, and the obstruction to the incoming air flow is smaller, that is, the wind resistance is lower, and the impact on the air volume attenuation is also smaller, which can further increase the air intake volume of the air-conditioning indoor unit 100 during heating or cooling, thereby further improving the heating or cooling capacity of the whole machine.

[0056] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, when the purification component 30 is in the second position, the purification component 30 is parallel to the first heat exchange part 21. In this technical solution, the purification component 30 is parallel to the first heat exchange part 21, so that the purification component 30 has a larger opening and closing degree relative to the shell wall where the air inlet 10a is located, which is conducive to further reducing the wind resistance of the air conditioner indoor unit 100 during heating or cooling, thereby further reducing the air intake attenuation, and enabling the air conditioner indoor unit 100 to have a larger air intake volume during heating or cooling, thereby further improving the heating or cooling capacity.

[0057] In some embodiments of the present invention, the driving member 40 is further configured to have at least three gears to drive the purification member 30 to switch between at least three positions, and the at least three positions include a first position and a second position.

[0058] It can be understood that the driving member 40 can not only drive the purification member 30 to switch between the first position and the second position, but also drive the purification member 30 to switch between more positions. When the purification member 30 is in different positions, the wind resistance formed by the purification member 30 at the air inlet 10a is different, so that different degrees of purification effect and air intake volume can be achieved. In the purification mode and heating or cooling mode of the air conditioner indoor unit 100, the driving member 40 can drive the purification member 30 in different positions to have more options and meet different requirements.

[0059] For example, when the air-conditioning indoor unit 100 is in purification mode, the driving component 40 drives the purification component 30 to switch between multiple positions, so that the air-conditioning indoor unit 100 can have multiple purification adjustment gears, so that the user can choose different purification adjustment gears according to needs, which is conducive to improving the user experience.

[0060] Optionally, the driving member 40 may be, but is not limited to, a servo motor and a palletizer, etc., thereby enabling the purification member 30 to be switched among at least three positions.

[0061] It should be noted that other structures and operations of the air conditioner indoor unit 100 of the embodiment of the utility model are known to those skilled in the art, and specific reference may be made to the air conditioner indoor unit in the related art. Figures 1 to 4 As shown, the air conditioner indoor unit 100 may further include a wind wheel 50, and the housing 10 further has an air outlet passage 10c and an air outlet 10b, and the wind wheel 50 is arranged in the air outlet passage 10c. When the air conditioner indoor unit 100 is working, the wind wheel 50 can drive air from the air inlet 10a into the air outlet passage 10c, and then be discharged outward from the air outlet 10b. When the air conditioner indoor unit 100 is in a heating or cooling mode, the heat exchanger 20 can perform heat exchange with the air entering the housing 10 to achieve heating or cooling.
