The embodiments described below with reference to the accompanying drawings are illustrative and are used only to interpret the present application, and cannot be understood as limitations on the present application.

[0025] The following disclosure provides a variety of different embodiments or examples for realizing different structures of the present application. To simplify the disclosure of the present application, specific example components and installations are described below. Of course, these are merely examples and are not intended to limit the present application. Also, the present application may repeatedly reference numbers and / or letters in different examples. This repetition is for the purposes of simplicity and clarity and does not in itself indicate a relationship between the various embodiments and / or installations discussed. Also, while the present application provides examples of various specific processes and materials, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0026] An air conditioning indoor unit 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0027] As shown in Figures 1 to 3 and 10, the air conditioning indoor unit 100 includes a housing 1 having an air outlet 10a, and a first air guide plate 2, and in order to achieve air outlet from the air conditioning indoor unit 100, the air flow within the housing 1 can be blown out through the air outlet 10a, and if the first air guide plate 2 extends along the longitudinal direction of the air conditioning indoor unit 100 (for example, the left-right direction in Figure 1), and the first air guide plate 2 is provided at the air outlet 10a so as to be rotatable around a first pivot axis 2R that is parallel to the longitudinal direction of the air conditioning indoor unit 100, the first air guide plate 2 can guide the air flow at the air outlet 10a and change the air flow direction at the air outlet 10a.

[0028] The air conditioning indoor unit 100 further includes a second air guide plate 3 and a third air guide plate 4, and the second air guide plate 3 and the third air guide plate 4 are provided in front of the first air guide plate 2 in the front-to-rear direction of the air conditioning indoor unit 100 (for example, the front-to-rear direction in FIG. 10 ), and the front-to-rear direction of the air conditioning indoor unit 100 is perpendicular to the longitudinal direction of the air conditioning indoor unit 100, and the second air guide plate 3 and the third air guide plate 4 extend along the longitudinal direction of the air conditioning indoor unit 100. The second air guide plate 3 and the third air guide plate 4 are arranged at intervals along the longitudinal direction of the air conditioning indoor unit 100, the second air guide plate 3 is arranged at the air outlet 10a so as to be rotatable around a second pivot axis 3R, and the third air guide plate 4 is arranged at the air outlet 10a so as to be rotatable around a third pivot axis 4R, and the second pivot axis 3R and the third pivot axis 4R are both parallel to the longitudinal direction of the air conditioning indoor unit 100.

[0029] The rotation of the second air guide plate 3 and the rotation of the third air guide plate 4 can be performed independently of each other, and there is no interlocking relationship between the state of the second air guide plate 3 (including the air guide angle, movement state, etc.) and the state of the third air guide plate 4. Therefore, when the air conditioning indoor unit 100 is operating, the state of the second air guide plate 3 may be the same as or different from the state of the third air guide plate 4, which effectively enriches the air blowing modes of the air conditioning indoor unit 100, and when the state of the second air guide plate 3 and the state of the third air guide plate 4 are different, the flow state of the air blown out from the second air guide plate 3 (flow direction, The airflow conditions of the air blown out from the third air guide plate 4 are different (including the airflow speed, etc.), and it is easy to achieve different airflow effects in the air-blowing area corresponding to the second air guide plate 3 and the air-blowing area corresponding to the third air guide plate 4, realizing divided airflow in the air-conditioning indoor unit 100 and satisfying the demand for differentiated airflow for different users. In turn, the air-conditioning indoor unit 100 can easily perform divided air-blowing control to meet the demands of different user groups in the same usage scenario, making it possible to simultaneously guarantee the comfort of different users.

[0030] For example, cases in which the state of the second air guide plate 3 and the state of the third air guide plate 4 are different can include, but are not limited to, the following: (1) when both the second air guide plate 3 and the third air guide plate 4 are in a certain air guide position, one of the second air guide plate 3 and the third air guide plate 4 guides air toward a first side of the air outlet 10a and the other guides air toward a second side of the air outlet 10a, the first side and the second side being opposite sides of the air outlet 10a; (2) when one of the second air guide plate 3 and the third air guide plate 4 is in a certain air guide position and the other oscillates back and forth; and (3) when both the second air guide plate 3 and the third air guide plate 4 oscillate back and forth and at least one of the oscillation width, oscillation frequency, etc. of the second air guide plate 3 and the third air guide plate 4 is different.

[0031] 5, the first pivot axis 2R, the second pivot axis 3R, and the third pivot axis 4R are all arranged in parallel, simplifying the design of the air conditioning indoor unit 100. The second air guide plate 3 and the third air guide plate 4 are both provided independently of the first air guide plate 2, and the rotation of the second air guide plate 3 and the rotation of the third air guide plate 4 are each independent of the first air guide plate 2, with no interlocking relationship between the state of the second air guide plate 3 and the state of the first air guide plate 2, and no interlocking relationship between the state of the third air guide plate 4 and the state of the first air guide plate 2. As a result, when the air conditioning indoor unit 100 is operating, the state of the first air guide plate 2 may be the same as or different from the state of the second air guide plate 3, and the state of the first air guide plate 2 may be the same as or different from the state of the third air guide plate 4, further expanding the air blowing modes of the air conditioning indoor unit 100.

[0032] Here, the edge of the second air guide plate 3 that is close to the second pivot axis 3R along the front-to-rear direction of the air conditioning indoor unit 100, and the edge of the third air guide plate 4 that is close to the third pivot axis 4R along the front-to-rear direction of the air conditioning indoor unit 100, both abut against the edge of the first air guide plate 2 that is away from the first pivot axis 1R along the front-to-rear direction of the air conditioning indoor unit 100, so that when the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all closed (as shown in Figures 1 to 3), the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 all close the air outlet 10a, achieving a good dust prevention effect, and when the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all open (as shown in Figures 9 to 17), the airflow is directed between the first air guide plate 2 and the second air guide plate 3, and between the first air guide plate 2 and the third air guide plate 4. At the same time, when the second air guide plate 3 and the third air guide plate 4 are both open and the first air guide plate 2 is closed (as shown in FIGS. 18 to 23), the first air guide plate 2 abuts against the second air guide plate 3 and the third air guide plate 4, so the airflow cannot be blown out between the first air guide plate 2 and the second air guide plate 3, nor can it be blown out between the first air guide plate 2 and the third air guide plate 4. At this time, the airflow can be guided and blown out via the side of the second air guide plate 3 that faces away from the first air guide plate 2 and the side of the third air guide plate 4 that faces away from the first air guide plate 2, further enhancing the air blowing modes of the air conditioning indoor unit 100.

[0033] According to the air conditioning indoor unit 100 of the embodiment of the present application, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are provided independently of one another, thereby effectively enriching the air flow modes of the air conditioning indoor unit 100 and realizing flexible adjustment of the air flow area. In order to simultaneously ensure the comfort of different users, divided air flow control is performed so that different air flow areas have the same or different airflow conditions in response to the needs of different user groups in the same usage scenario.

[0034] In some embodiments, the second pivot axis 3R coincides with the third pivot axis 4R, which facilitates a simpler design of the air conditioning indoor unit 100. For example, the second air guide plate 3 and the third air guide plate 4 can be arranged symmetrically. Of course, the second pivot axis 3R and the third pivot axis 4R can also be installed in parallel, which can enrich the structural design of the air conditioning indoor unit 100 and better meet the needs of actual differentiation.

[0035] In some embodiments of the present application, as shown in Fig. 4, the air conditioning indoor unit 100 further includes a first drive mechanism 81 for driving the rotation of the first air guide plate 2. For example, the first drive mechanism 81 includes a first drive motor 811 whose output shaft is directly or indirectly connected to the first air guide plate 2, and in the example of Fig. 4, the first drive mechanism 81 further includes a first boss 812 that is inserted into and pivotally fitted into a mounting hole in the housing 1, and the first boss 812, the output shaft of the first drive motor 811, and the first air guide plate 2 are all positioned circumferentially of the output shaft, and transmits power of the first drive motor 811 to the first air guide plate 2.

[0036] In some embodiments, if one end of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100 is connected to the first drive mechanism 81 and the other end of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100 is pivotally connected to the housing 1, then both ends of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100 are supported by the first drive mechanism 81 and the housing 1, respectively, thereby ensuring secure attachment and stable rotation of the first air guide plate 2, and in this case, a connection part 21 that is pivotally connected to the housing 1 is further provided between both ends of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100, which further improves the stability of the first air guide plate 2 and enables stable rotation of the first air guide plate 2 even when the weight of the first air guide plate 2 is heavy.

[0037] 4 to 6, if there are two first drive mechanisms 81 and both ends of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100 are connected to the two corresponding first drive mechanisms 81, then the two first drive mechanisms 81 are provided at both ends of the first air guide plate 2, and the two first drive mechanisms 81 together drive the rotation of the first air guide plate 2, and both ends of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100 are supported by the first drive mechanisms 81, ensuring reliable installation and operation of the first air guide plate 2. Meanwhile, a connection part 21 that is pivotally connected to the housing 1 is provided between both ends of the first air guide plate 2 in the longitudinal direction of the air conditioning indoor unit 100, further improving the stability of the first air guide plate 2 and enabling stable rotation of the first air guide plate 2 even when the weight of the first air guide plate 2 is heavy. The connecting portion 21 is formed with one of a pivot hole and a pivot shaft, and the housing 1 is provided with the other of a pivot hole and a pivot shaft, and the pivot shaft is pivotally fitted into the pivot hole, thereby realizing smooth rotation of the first air guide plate 2.

[0038] In some embodiments of the present application, as shown in Fig. 4 , the air conditioning indoor unit 100 further includes a second drive mechanism 82 for driving the rotation of the second air guide plate 3, and a third drive mechanism 83 for driving the rotation of the third air guide plate 4. For example, the second drive mechanism 82 includes a second drive motor 821 having an output shaft directly or indirectly connected to the second air guide plate 3, and the third drive mechanism 83 includes a third drive motor 831 having an output shaft directly or indirectly connected to the third air guide plate 4. In the example of Fig. 4 , the second drive mechanism 82 further includes a second boss 822 connected between the second drive motor 821 and the second air guide plate 3 to realize power transmission, and the third drive mechanism 83 further includes a third boss 832 connected between the third drive motor 831 and the third air guide plate 4 to realize power transmission.

[0039] If one end of the second air guide plate 3 that is away from the third air guide plate 4 along the longitudinal direction of the air conditioning indoor unit 100 is connected to the second drive mechanism 82, and one end of the second air guide plate 3 that is close to the third air guide plate 4 along the longitudinal direction of the air conditioning indoor unit 100 is pivotally connected to the housing 1, then both ends of the second air guide plate 3 in the longitudinal direction of the air conditioning indoor unit 100 are supported by the second drive mechanism 82 and the housing 1, respectively, and reliable attachment and stable rotation of the second air guide plate 3 can be ensured. If one end of the third air guide plate 4 that is away from the second air guide plate 3 along the longitudinal direction of the air conditioning indoor unit 100 is connected to the third drive mechanism 83, and one end of the third air guide plate 4 that is close to the second air guide plate 3 along the longitudinal direction of the air conditioning indoor unit 100 is pivotally connected to the housing 1, then both ends of the third air guide plate 4 in the longitudinal direction of the air conditioning indoor unit 100 will be supported by the third drive mechanism 83 and the housing 1, respectively, ensuring secure attachment and stable rotation of the third air guide plate 4.

[0040] For example, in the longitudinal direction of the air conditioning indoor unit 100, the second air guide plate 3 and the third air guide plate 4 can be positioned between the second drive mechanism 82 and the third drive mechanism 83, which means that the second drive mechanism 82 and the third drive mechanism 83 will not occupy the space between the second air guide plate 3 and the third air guide plate 4, reducing the distance between the second air guide plate 3 and the third air guide plate 4 in the longitudinal direction of the air conditioning indoor unit 100, reducing the airflow flowing out from between the second air guide plate 3 and the third air guide plate 4, and ensuring the effect of the second air guide plate 3 and the third air guide plate 4 in guiding the airflow at the air outlet 10a.

[0041] For example, in the example of Figure 4, in the longitudinal direction of the air conditioning indoor unit 100, pivot holes that pivotally fit onto corresponding pivot shafts of the housing 1 are formed at one end of the second air guide plate 3 that is close to the third air guide plate 4 and at one end of the third air guide plate 4 that is close to the second air guide plate 3, in order to achieve smooth pivoting of the second air guide plate 3 and the third air guide plate 4.

[0042] In some embodiments of the present application, the air conditioning indoor unit 100 has a one-sided air-blowing mode, in which the first air guide plate 2 opens the air outlet 10a, one of the second air guide plate 3 and the third air guide plate 4 opens the air outlet 10a, and the other covers the air outlet 10a, and at this time, air can be blown out between the first air guide plate 2 and the second air guide plate 3, between the first air guide plate 2 and the third air guide plate 4, and through one side of the second air guide plate 3 and the third air guide plate 4 that faces away from the first air guide plate 2, but cannot be blown out through the one side of the second air guide plate 3 and the third air guide plate 4 that faces away from the other first air guide plate 2.

[0043] It can be understood that in the one-sided airflow mode, the first air guide plate 2 may always be held at a certain angular position or may oscillate back and forth, and the open one of the second air guide plate 3 and the third air guide plate 4 may always be held at a certain angular position or may oscillate back and forth.

[0044] 4, the second air guide plate 3 and the third air guide plate 4 are installed at a distance from each other along the longitudinal direction of the air conditioning indoor unit 100. In the one-side blowing mode, the first air guide plate 2 is open, the second air guide plate 3 is open, and the third air guide plate 4 is closed, so that air can be blown out between the first air guide plate 2 and the second air guide plate 3, between the first air guide plate 2 and the third air guide plate 4, and through the side of the second air guide plate 3 facing away from the first air guide plate 2, but cannot be blown out through the side of the third air guide plate 4 facing away from the first air guide plate 2. As a result, the amount of air blown out from the right side of the air conditioning indoor unit 100 is greater than the amount of air blown out from the left side, which better meets the actual demands of the user. Of course, in the one-side blowing mode, it is also possible to open the first air guide plate 2, close the second air guide plate 3, and open the third air guide plate 4.

[0045] In some embodiments, in the one-side air-blowing mode, the first air guide plate 2 can guide air toward one side of the air outlet 10a. For example, in the examples of FIGS. 1 and 9, the air conditioning indoor unit 100 is a wall-mounted air conditioning indoor unit, the air outlet 10a extends substantially horizontally, and in the one-side air-blowing mode, the first air guide plate 2 can guide air upward to form a ceiling airflow. Note that in the one-side air-blowing mode, the setting of the air guide angle of the first air guide plate 2 may be controlled by the user or by the first drive mechanism 81. For example, in the one-side air-blowing mode, the first air guide plate 2 is rotated upward to a corresponding angle by the drive of the first drive mechanism 81 to guide air upward, the second air guide plate 3 is opened to a corresponding angle by the drive of the second drive mechanism 82 to guide air upward, and the third air guide plate 4 is closed by the drive of the third drive mechanism 83.

[0046] As shown in Figures 9 to 17, the air conditioning indoor unit 100 further has a double-sided air-blowing mode, and in the double-sided air-blowing mode, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 all open the air outlets 10a, so that the airflow can be blown out between the first air guide plate 2 and the second air guide plate 3, between the first air guide plate 2 and the third air guide plate 4, through one side of the second air guide plate 3 facing away from the first air guide plate 2, and through one side of the third air guide plate 4 facing away from the first air guide plate 2.

[0047] It can be understood that in the double-side airflow mode, the first air guide plate 2 may always be held at a certain angular position or may oscillate back and forth, the second air guide plate 3 may always be held at a certain angular position or may oscillate back and forth, and the third air guide plate 4 may always be held at a certain angular position or may oscillate back and forth. Among these, when the state of the second air guide plate 3 and the state of the third air guide plate 4 are different, divided airflow of the air conditioning indoor unit 100 can be realized.

[0048] In some embodiments of the present application, the double-sided airflow mode includes a first divided airflow mode, in which one of the second air guide plate 3 and the third air guide plate 4 guides air in a direction away from the first air guide plate 2, and the other guides air in a direction closer to the first air guide plate 2, thereby ensuring the divided airflow effect of the air conditioning indoor unit 100.

[0049] 4, the air outlet 10a extends substantially horizontally, the second air guide plate 3 and the third air guide plate 4 are provided with a gap between them on the left and right, and in the first divided air flow mode, the first air guide plate 2 is always held at a certain angular position, and the second air guide plate 3 guides air upward in a direction away from the first air guide plate 2, thereby forming a ceiling airflow and allowing the airflow to flow along the upper side of the room, and the third air guide plate 4 guides air downward in a direction approaching the first air guide plate 2, forming a waterfall-type airflow and allowing the airflow to flow along the floor surface. Of course, in the first divided air flow mode, the second air guide plate 3 can also guide air in a direction approaching the first air guide plate 2, or the third air guide plate 4 can also guide air in a direction away from the first air guide plate 2.

[0050] 1 to 4, the air conditioning indoor unit 100 further includes a first blade set 71 provided at the air outlet 10a and corresponding to the second air guide plate 3. For example, when the first blade set 71 is located on one side of the second air guide plate 3 close to the center of the housing 1, the first blade set 71 and the second air guide plate 3 can guide the airflow on the same side at the air outlet 10a. The first blade set 71 includes at least one rotatable first blade 711, and the rotation axis of the first blade 711 may be perpendicular to the second pivot axis 3R. The air conditioning indoor unit 100 further includes a second blade set 72 provided at the air outlet 10a and corresponding to the third air guide plate 4. For example, when the second blade set 72 is located on one side of the third air guide plate 4 close to the center of the housing 1, the second blade set 72 and the third air guide plate 4 can guide the airflow on the same side at the air outlet 10a. The second blade set 72 includes at least one rotatable second blade 721, and the rotation axis of the second blade 721 may be perpendicular to the third pivot axis 4R.

[0051] Obviously, the first blade group 71 and the second blade group 72 are provided independently, and the first blade 711 and the second blade 721 can be driven to rotate by different drive motors, respectively. In this case, the double-side blowing mode of the air conditioning indoor unit 100 can further include a second divided blowing mode, and in the second divided blowing mode, if the first blade group 71 and the second blade group 72 direct air in different directions, the air guide angle of the first blade group 71 and the air guide angle of the second blade group 72 will be different, and the divided blowing effect of the air conditioning indoor unit 100 will be ensured.

[0052] In some embodiments, as shown in FIG. 4, the air outlet 10a extends along the longitudinal direction of the air conditioning indoor unit 100, and the first blade group 71 and the second blade group 72 swing left and right to guide the air, with the first blade group 71 located to the right of the second blade group 72, and in the second divided air blowing mode, the first air guide plate 2 is always held at a certain angular position, the first blade 711 is always held at a certain angular position and guides the air toward the front of the air outlet 10a, allowing the corresponding airflow to be blown out approximately vertically toward the front, and the second blade 721 is always held at a certain angular position and guides the air toward the left side of the air outlet 10a, allowing the corresponding airflow to be blown out along the edge of the room.

[0053] Of course, the airflow state in the second divided airflow mode is not limited to this, as long as the airflow angle of the first blade 711 is different from the airflow angle of the second blade 721. Meanwhile, in the second divided airflow mode, the states of the first airflow guide plate 2, the second airflow guide plate 3, and the third airflow guide plate 4 can be set to any appropriate state according to actual needs.

[0054] When the air conditioning indoor unit 100 has a first divided airflow mode and includes a first blade group 71 and a second blade group 72, it can be understood that in the first divided airflow mode, the states of the first blade group 71 and the second blade group 72 can be set to any appropriate state according to actual demand.

[0055] In some embodiments, the first blade set 71 and the second blade set 72 are arranged symmetrically. The first blade set 71 includes a first link 712 and first blades 711, the rotation axis of the first blades 711 being perpendicular to the longitudinal direction of the air conditioning indoor unit 100, and the first link 712 can synchronously rotate the multiple first blades 711. The second blade set 72 includes a second link 722 and second blades 721, the rotation axis of the second blades 721 being perpendicular to the longitudinal direction of the air conditioning indoor unit 100, and the second link 722 can synchronously rotate the multiple second blades 721.

[0056] In some embodiments of the present application, the two-sided airflow mode can further include a third divided airflow mode, in which the second air guide plate 3 and the third air guide plate 4 respectively guide air toward opposite sides of the air outlet 10a, and the first blade group 71 and the second blade group 72 respectively guide air toward different directions.

[0057] In some embodiments of the present application, as shown in FIG. 4 , the air conditioning indoor unit 100 further includes a fourth air guide plate 5, the fourth air guide plate 5 is located inside the second air guide plate 3 and extends along the longitudinal direction of the air conditioning indoor unit 100, the fourth air guide plate 5 is provided at the air outlet 10a so as to be rotatable around a fourth pivot axis 5R, the fourth pivot axis 5R is adjacent to one side of the second air guide plate 3 that is away from the first air guide plate 2, and the fourth air guide plate 5 has a If a plurality of first air diffusion holes 50 are formed penetrating along the thickness direction and the fourth air guide plate 5 can move between a shielding position that shields the air outlet 10a and a retracted position that opens the air outlet 10a, when the fourth air guide plate 5 is in the shielding position, the air flow flowing from the air outlet 10a to the fourth air guide plate 5 is softened by the air diffusion action of the first air diffusion holes 50, and the air conditioning indoor unit 100 can easily blow air without creating a windless feeling.

[0058] Among these, the fact that the fourth air guide plate 5 is located inside the second air guide plate 3 can be understood as meaning that when the second air guide plate 3 is closed, the fourth air guide plate 5 is located on one side of the second air guide plate 3 facing the center of the housing 1.

[0059] The air conditioning indoor unit 100 further includes a fifth air guide plate 6, which is located inside the third air guide plate 4 and extends along the longitudinal direction of the air conditioning indoor unit 100. The fifth air guide plate 6 is rotatably mounted on the air outlet 10a around a fifth pivot axis 6R, the fifth pivot axis 6R being adjacent to one side of the third air guide plate 4 that is away from the first air guide plate 2. The fifth air guide plate 6 has a plurality of second air diffusion holes 60 that penetrate through it in the thickness direction, and if the fifth air guide plate 6 can move between a blocking position that blocks the air outlet 10a and a retracted position that opens the air outlet 10a, when the fifth air guide plate 6 is in the blocking position, the airflow flowing from the air outlet 10a to the fifth air guide plate 6 is softened by the air diffusion action of the second air diffusion holes 60, and the air conditioning indoor unit 100 can easily deliver air without a windy feeling.

[0060] The fact that the fifth air guide plate 6 is located inside the third air guide plate 4 can be understood as meaning that when the third air guide plate 4 is closed, the fifth air guide plate 6 is located on one side of the third air guide plate 4 facing the center of the housing 1.

[0061] For example, when the second air guide plate 3 is open, if the fourth air guide plate 5 is located in the blocking position, the fourth air guide plate 5 can block the portion of the air outlet 10a located on one side of the second air guide plate 3 facing away from the first air guide plate 2, making the airflow blown out via the one side of the second air guide plate 3 facing away from the first air guide plate 2 relatively soft, and if the fourth air guide plate 5 is located in the blocking position, it can be ensured that the fourth air guide plate 5 does not affect the airflow blown out via the one side of the second air guide plate 3 facing away from the first air guide plate 2. When the third air guide plate 4 is open, if the fifth air guide plate 6 is located in the blocking position, the fifth air guide plate 6 can block the portion of the air outlet 10a located on one side of the third air guide plate 4 facing away from the first air guide plate 2, making the airflow blown out via the one side of the third air guide plate 4 facing away from the first air guide plate 2 relatively soft, and if the fifth air guide plate 6 is located in the blocking position, it can be ensured that the fifth air guide plate 6 does not affect the airflow blown out via the one side of the third air guide plate 4 facing away from the first air guide plate 2.

[0062] Wherein, as long as the fifth air guide plate 6 and the fourth air guide plate 5 are installed at an interval along the longitudinal direction of the air conditioning indoor unit 100, the movement of the fourth air guide plate 5 and the movement of the fifth air guide plate 6 may be independent of each other, and there is no interlocking relationship between the state of the fourth air guide plate 5 (including its current position, movement state, etc.) and the state of the fifth air guide plate 6, and when the air conditioning indoor unit 100 is operating, the state of the fourth air guide plate 5 may be the same as or different from the state of the fifth air guide plate 6, which can further enrich the air blowing modes of the air conditioning indoor unit 100.

[0063] 5, the fourth pivot axis 5R and the fifth pivot axis 6R are both parallel to the longitudinal direction of the air conditioning indoor unit 100. In some cases, the fourth pivot axis 5R and the fifth pivot axis 6R may be aligned to further simplify the design of the air conditioning indoor unit 100; for example, the fourth air guide plate 5 and the fifth air guide plate 6 may be installed symmetrically. Of course, the fourth pivot axis 5R and the fifth pivot axis 6R may also be installed parallel to each other, which may enrich the structural design of the air conditioning indoor unit 100 and better meet actual differentiation needs.

[0064] 10, 11, 22, and 23, an air passage 10 having an air outlet 10a is defined within the housing 1, and one side of the air passage 10 close to the air outlet 10a has a first wall surface 10b and a second wall surface 10c that are installed opposite each other, the first wall surface 10b may be located in front of the second wall surface 10c, and the fourth air guide plate 5 and the fifth air guide plate 6 are both installed close to the first wall surface 10b, and the first air guide plate 2 is installed close to the second wall surface 10c. In the retracted position, both the fourth air guide plate 5 and the fifth air guide plate 6 are installed close to the first wall surface 10b. A first accommodating groove 10d and a second accommodating groove 10e are provided on the first wall surface 10b, and in the retracted position, the fourth air guide plate 5 is accommodated in the first accommodating groove 10d and the fifth air guide plate 6 is accommodated in the second accommodating groove 10e, and in the blocking position, the fourth air guide plate 5 is removed from the first accommodating groove 10d and blocks part of the air outlet 10a, and the fifth air guide plate 6 is removed from the second accommodating groove 10e and blocks part of the air outlet 10a.

[0065] 4 and 5 , the air conditioning indoor unit 100 further includes a fourth drive mechanism 84 for driving the rotation of the fourth air guide plate 5 and a fifth drive mechanism 85 for driving the rotation of the fifth air guide plate 6, facilitating independent operation of the fourth air guide plate 5 and the fifth air guide plate 6. One end of the fourth air guide plate 5 along the longitudinal direction of the air conditioning indoor unit 100 and away from the fifth air guide plate 6 is connected to the fourth drive mechanism 84, and one end of the fourth air guide plate 5 along the longitudinal direction of the air conditioning indoor unit 100 and close to the fifth air guide plate 6 is pivotally connected to the housing 1. If this is the case, then both ends of the fourth air guide plate 5 in the longitudinal direction of the air conditioning indoor unit 100 are supported by the fourth drive mechanism 84 and the housing 1, respectively, which ensures secure attachment and stable rotation of the fourth air guide plate 5. If one end of the fifth air guide plate 6 that is away from the fourth air guide plate 5 along the longitudinal direction of the air conditioning indoor unit 100 is connected to the fifth drive mechanism 85, and one end of the fifth air guide plate 6 that is close to the fourth air guide plate 5 along the longitudinal direction of the air conditioning indoor unit 100 is pivotally connected to the housing 1, then both ends of the fifth air guide plate 6 in the longitudinal direction of the air conditioning indoor unit 100 are supported by the fifth drive mechanism 85 and the housing 1, respectively, ensuring secure attachment and stable rotation of the fifth air guide plate 6.

[0066] For example, the fourth drive mechanism 84 may include a fourth drive motor 841 and a fourth boss 842 connected between the fourth drive motor 841 and the fourth air guide plate 5 to achieve power transmission. The fifth drive mechanism 85 may include a fifth drive motor 851 and a fifth boss 852 connected between the fifth drive motor 851 and the fifth air guide plate 6 to achieve power transmission.

[0067] In some embodiments of the present application, the air conditioning indoor unit 100 has windless modes including a double windless mode. In the double windless mode, the second air guide plate 3 and the third air guide plate 4 both open the air outlet 10a, the fourth air guide plate 5 and the fifth air guide plate 6 are both located in the blocking position, the second air guide plate 3 is close to the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, for example, the second air guide plate 3 is in contact with the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, and the third air guide plate 4 is close to the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, for example, the third air guide plate 4 is in contact with the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, The plate 4 is in contact with the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, and the fourth air guide plate 5 shields the portion of the second air guide plate 3 of the air outlet 10a that is located on one side facing away from the first air guide plate 2, and the fifth air guide plate 6 makes it easy to shield the portion of the third air guide plate 4 of the air outlet 10a that is located on one side facing away from the first air guide plate 2, so that the air blown out from both sides of the air outlet 10a in the longitudinal direction of the air conditioning indoor unit 100 becomes relatively soft.

[0068] In some examples, in the double-sided no-wind mode, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all installed with a gap between them, the fourth air guide plate 5 moves in cooperation with the second air guide plate 3, so that the fourth air guide plate 5 and the second air guide plate 3 block part of the air outlet 10a and the fourth air guide plate 5 can shield a part of the second air guide plate 3 of the air outlet 10a that is located away from the first air guide plate 2, and the fifth air guide plate 6 moves in cooperation with the third air guide plate 4, so that the fifth air guide plate 6 and the third air guide plate 4 block part of the air outlet 10a and the fifth air guide plate 6 can shield a part of the third air guide plate 4 of the air outlet 10a that is located away from the first air guide plate 2. At this time, a portion of the airflow corresponding to the second air guide plate 3 at the air outlet 10a flows out through the fourth air guide plate 5 to realize a soft blow-out airflow, and another portion flows out through the gap between the second air guide plate 3 and the first air guide plate 2, and a portion of the airflow corresponding to the third air guide plate 4 at the air outlet 10a flows out through the fifth air guide plate 6 to realize a soft blow-out airflow, and another portion flows out through the gap between the third air guide plate 4 and the first air guide plate 2.

[0069] Alternatively, in the double-sided no-wind mode, the first air guide plate 2 abuts against the second air guide plate 3 and the third air guide plate 4, respectively, the fourth air guide plate 5 can shield a portion of the second air guide plate 3 of the air outlet 10a located on one side facing away from the first air guide plate 2, and the fifth air guide plate 6 can shield a portion of the third air guide plate 4 of the air outlet 10a located on one side facing away from the first air guide plate 2. At this time, almost all of the airflow corresponding to the second air guide plate 3 at the air outlet 10a flows out via the fourth air guide plate 5 to achieve a soft blown-out air, and almost all of the airflow corresponding to the third air guide plate 4 at the air outlet 10a flows out via the fifth air guide plate 6 to achieve a soft blown-out air.

[0070] In some embodiments of the present application, the air conditioning indoor unit 100 has windless modes including a one-sided windless mode. In the one-sided windless mode, the second air guide plate 3 opens the air outlet 10a, the fourth air guide plate 5 is located at the blocking position, the second air guide plate 3 is close to the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, for example, the second air guide plate 3 is in contact with the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, the fifth air guide plate 6 is located at the retracted position, and the third air guide plate 4 blocks the air outlet 10a. At this time, part of the air blown out of the air outlet 10a corresponding to the one side where the second air guide plate 3 is located is blocked by the fourth air guide plate 5 to achieve soft airflow. Some of the air flows out through the gap between the second air guide plate 3 and the first air guide plate 2, and almost all of the air blown out from the air outlet 10a corresponding to the one side where the third air guide plate 4 is located is blown out between the third air guide plate 4 and the first air guide plate 2. This reduces the amount of air blown out from the gap around the third air guide plate 4, thereby reducing noise, and also reduces the loss of air blown out from the air outlet 10a corresponding to the one side where the third air guide plate 4 is located by passing through the second wind diffusion holes, thereby improving the heating and cooling efficiency in the one-side no-wind mode.

[0071] Alternatively, in the one-sided no-wind mode, the third air guide plate 4 opens the air outlet 10a, the fifth air guide plate 6 is positioned at the blocking position, the third air guide plate 4 is close to the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, for example, the third air guide plate 4 is in contact with the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, the fourth air guide plate 5 is positioned at the retracted position, and the second air guide plate 3 blocks the air outlet 10a, thereby reducing the amount of air blowing out from the gap around the second air guide plate 3 and reducing noise.

[0072] As a result, in the one-side windless mode, the air blown out from one side of the air outlet 10a in the longitudinal direction of the air conditioning indoor unit 100 is softened, which is advantageous for reducing operating noise in this mode.

[0073] Of course, the present application is not limited to this, and in the one-sided no-wind mode, the first air guide plate 2 may be configured to open the air outlet 10a until it is spaced apart from the second air guide plate 3 and the third air guide plate 4, the second air guide plate 3 and the third air guide plate 4 both have their air outlets 10a open, and one of the fourth air guide plate 5 and the fifth air guide plate 6 is positioned in the blocking position, so that wind does not blow out from the gaps around the second air guide plate 3 or the third air guide plate 4 and cause noise.

[0074] In some embodiments, in the one-side blowing mode, a soft airflow can be achieved by opening the first air guide plate 2, opening one of the second air guide plate 3 and the third air guide plate 4, and closing the other, and at this time, the fourth air guide plate 5 or the fifth air guide plate 6 can be positioned in the blocking position, corresponding to the opening of one of the second air guide plate 3 and the third air guide plate 4. For example, to achieve a soft airflow in the one-side blowing mode, the first air guide plate 2 and the second air guide plate 3 can both be opened, the third air guide plate 4 can be closed, the fourth air guide plate 5 can be positioned in the blocking position, and at this time the fifth air guide plate 6 can be positioned in the retracted position.

[0075] In some embodiments, in the double-sided blowing mode, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 all open the air outlets 10a to realize one-sided soft blowing, or double-sided soft blowing. For example, in the double-sided blowing mode, the fourth air guide plate 5 or the fifth air guide plate 6 can be placed in the closed position to realize one-sided soft blowing, and also, for example, in the double-sided blowing mode, the fourth air guide plate 5 and the fifth air guide plate 6 can both be placed in the closed position to realize double-sided soft blowing.

[0076] 4 and 5, the air conditioning indoor unit 100 further includes a first blade set 71 provided at the air outlet 10a and corresponding to the second air guide plate 3. For example, when the first blade set 71 is located on one side of the second air guide plate 3 close to the center of the housing 1, the first blade set 71 and the second air guide plate 3 can guide the airflow on the same side at the air outlet 10a. The first blade set 71 includes at least one rotatable first blade 711.

[0077] The air conditioning indoor unit 100 further includes a second blade set 72 provided at the air outlet 10a and corresponding to the third air guide plate 4. For example, when the second blade set 72 is located on one side of the third air guide plate 4 close to the center of the housing 1, the second blade set 72 and the third air guide plate 4 can guide the airflow on the same side of the air outlet 10a. The second blade set 72 includes at least one rotatable second blade 721.

[0078] The air conditioning indoor unit 100 has windless modes, including a one-sided windless person avoidance mode. In the one-sided windless person avoidance mode, the second and third air guide plates 3 and 4 both open the air outlet 10a, the fourth air guide plate 5 closest to the user is positioned in the blocking position, the second air guide plate 3 is close to the edge of the fourth air guide plate 5 that faces away from the fourth pivot axis 5R—for example, the second air guide plate 3 is in contact with the edge of the fourth air guide plate 5 that faces away from the fourth pivot axis 5R—the fifth air guide plate 6 is positioned in the retracted position, and the second blade set 72 guides air in a direction away from the first blade set 71, thereby preventing the air discharged from the air conditioning indoor unit 100 from blowing directly toward the user, ensuring the airflow volume of the air conditioning indoor unit 100 and the heat exchange effect of the air conditioning indoor unit 100, and easily achieving the goal of a cool, windless feeling.

[0079] For example, when a user is close to one side where the fourth air guide plate 5 is located, in the one-sided no-wind-sense person avoidance mode, the first air guide plate 2 opens the air outlet 10a until it is installed with a gap between it and the second air guide plate 3 and the third air guide plate 4, the fourth air guide plate 5 is located in the blocking position, the edge of the fourth air guide plate 5 away from the fourth pivot axis 5R is brought into contact with the second air guide plate 3, the fifth air guide plate 6 is located in the retracted position, the second blade set 72 guides air in a direction away from the first blade set 71, and at this time the second air guide plate 3 opens the air outlet 10a and the third air guide plate 4 turns the air outlet 10a on or off.

[0080] Alternatively, in the one-sided no-wind-sense person avoidance mode, the second air guide plate 3 and the third air guide plate 4 both open the air outlet 10a, the fifth air guide plate 6 closer to the user is positioned in the shielding position, the third air guide plate 4 is close to the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, for example, the third air guide plate 4 is in contact with the edge of the fifth air guide plate 6 that is away from the fifth pivot axis 6R, the fourth air guide plate 5 is positioned in the retracted position, and the first blade group 71 guides air in a direction away from the second blade group 72.

[0081] For example, when a user is close to one side where the fifth air guide plate 6 is located, in the one-sided no-wind-sense person avoidance mode, the first air guide plate 2 opens the air outlet 10a until it is installed with a gap between it and the second air guide plate 3 and the third air guide plate 4, the fifth air guide plate 6 is located in the blocking position, the edge of the fifth air guide plate 6 away from the fifth pivot axis 6R is brought into contact with the third air guide plate 4, the fourth air guide plate 5 is located in the retracted position, the first blade group 71 guides air in a direction away from the second blade group 72, and at this time the third air guide plate 4 opens the air outlet 10a and the second air guide plate 3 turns the air outlet 10a on or off.

[0082] For example, in the example of FIG. 4 , the first blade group 71 is located to the right of the second blade group 72, the first blade group 71 is installed to correspond to the fourth air guide plate 5 and the second air guide plate 3, and the second blade group 72 is installed to correspond to the fifth air guide plate 6 and the third air guide plate 4. In the one-sided no-wind-sense person avoidance mode, when the air conditioning indoor unit 100 detects that a user is located on the right side of the air conditioning indoor unit 100, to ensure the comfort of the user, the first air guide plate 2 is opened until it is spaced apart from the second air guide plate 3 and the third air guide plate 4, and then the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all opened, the fourth air guide plate 5 is in the shielding position, the fifth air guide plate 6 is in the retracted position, and the second blade group 72 guides air towards the left side of the air conditioning indoor unit 100.

[0083] It can be understood that in the one-sided no-wind-sense human avoidance mode, the air guide angle of the air guide plate, the air guide angle of the first blade group 71 and the air guide angle of the second blade group 72 can be remotely adjusted and controlled by the user, and the recognition of the user's location can also be automatically adjusted and controlled by the sensors of the air conditioning indoor unit 100.

[0084] In some embodiments of the present application, in the windless mode, the first air guide plate 2 opens the air outlet 10a. For example, in the double-windless mode, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 all open the air outlet 10a, and the first air guide plate 2 is arranged to be spaced apart from the second air guide plate 3 and the third air guide plate 4, or the first air guide plate 2 is arranged to be in contact with the second air guide plate 3 and the third air guide plate 4. For example, in the one-sided windless mode, the first air guide plate 2 opens the air outlet 10a, and the first air guide plate 2 is arranged to be spaced apart from the second air guide plate 3 and the third air guide plate 4. Of course, in the one-sided windless mode, the first air guide plate 2 can also open the air outlet 10a and be in contact with the second air guide plate 3 and the third air guide plate 4.

[0085] If the air conditioning indoor unit 100 uses a cross-flow fan wheel to blow air, and if there is one cross-flow fan wheel, the cross-flow fan wheel corresponds to each of the second air guide plate 3 and the third air guide plate 4. In this case, in the one-sided no-wind mode, if one of the second air guide plate 3 and the third air guide plate 4 is closed and the first air guide plate 2 moves until it abuts against the second air guide plate 3 and the third air guide plate 4, a large amount of air will blow out from the gap around one of the second air guide plate 3 and the third air guide plate 4, generating noise. For this reason, in the present application, by opening the first air guide plate 2 until it is spaced apart from the second air guide plate 3 and the third air guide plate 4, the amount of air blown out from the gap around the third air guide plate 4 or the gap around the second air guide plate 3 can be effectively reduced, thereby effectively reducing noise.

[0086] In some embodiments of the present application, the double-sided no-wind mode includes a first stage, a second stage, and a third stage, as shown in Figures 15 to 20. In the first stage, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all open, the first air guide plate 2 is disposed at a distance from each of the second air guide plate 3 and the third air guide plate 4, and airflow can be blown out between the first air guide plate 2 and the second air guide plate 3, between the first air guide plate 2 and the third air guide plate 4, through one side of the second air guide plate 3 facing away from the first air guide plate 2, and through one side of the third air guide plate 4 facing away from the first air guide plate 2. In the second stage, the first air guide plate 2 abuts against the second air guide plate 3 and the third air guide plate 4, and the airflow cannot be blown out between the first air guide plate 2 and the second air guide plate 3, nor can it be blown out between the first air guide plate 2 and the third air guide plate 4. The airflow can be guided and blown out via one side of the second air guide plate 3 facing away from the first air guide plate 2 and one side of the third air guide plate 4 facing away from the first air guide plate 2. In the third stage, the fourth air guide plate 5 and the fifth air guide plate 6 are both positioned in the blocking position, and part of the airflow at the air outlet 10a is dispersed via the first air diffusion holes 50, and the other part is dispersed via the second air diffusion holes 60, thereby realizing a soft blown air.

[0087] 15 to 17, in the first stage, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 move together to guide the airflow from the air outlet 10a substantially horizontally, preventing the airflow from blowing directly toward the user and ensuring that the airflow has a certain capacity output so that the indoor temperature meets the user's needs. In the second stage, as shown in FIGS. 18 to 20, the first air guide plate 2 rotates upward from its first-stage position until it abuts against the second air guide plate 3 and the third air guide plate 4, respectively, achieving a tight fit between the edges of the first air guide plate 2 and the second and third air guide plates 3 and 4, thereby reducing the airflow output and alleviating the user's sense of wind. In the third stage, both the fourth air guide plate 5 and the fifth air guide plate 6 can be moved from the retracted position to the shielding position, and at this time, the fourth air guide plate 5 abuts against the second air guide plate 3, and the fifth air guide plate 6 abuts against the third air guide plate 4, thereby achieving dispersion of all airflow from the air outlet 10a.

[0088] For example, predetermined conditions such as the temperature and / or humidity of the airflow area may be set according to actual demand, and the air conditioning indoor unit 100 can control the progression stage of the double-sided no-wind mode depending on whether the predetermined conditions are met. For example, if it is determined that a first predetermined condition is met, the air conditioning indoor unit 100 can proceed to the second stage, and if it is determined in the second stage that both the first airflow area corresponding to the second air guide plate 3 and the second airflow area corresponding to the third air guide plate 4 meet the second predetermined condition, the air conditioning indoor unit 100 proceeds to the third stage. If the air conditioning indoor unit 100 determines that at least one of the first air blowing area and the second air blowing area described above does not satisfy the second predetermined condition, the air conditioning indoor unit 100 returns to the first stage, and if it determines in the third stage that both the first air blowing area and the second air blowing area satisfy the third predetermined condition, the air conditioning indoor unit 100 can proceed to the third stage, and conversely, if it determines that at least one of the first air blowing area and the second air blowing area does not satisfy the third predetermined condition, the air conditioning indoor unit 100 returns to the second stage.

[0089] As a result, the area division control realizes stages in which the windless state of the area corresponding to the air outlet 10a can be individually controlled depending on the temperature and humidity of the actual air blowing area, and at different windless stages, the first blade group 71 and the second blade group 72 can rotate correspondingly to adapt to the corresponding windless stage.

[0090] In some embodiments, the air conditioning indoor unit 100 has a cooling mode, and in cooling mode, as shown in Figures 9 to 11, the tangential extension planes of the first air guide plate 2 and the second wall surface 10c of air passage 10 substantially coincide, and at this time, the cooperation of the upstream end of the first air guide plate 2 and the downstream end of the second wall surface 10c corresponds to extending air passage 10, thereby effectively increasing the air blowing distance and achieving a good cooling effect. The second air guide plate 3 and the third air guide plate 4 are both substantially parallel to the first air guide plate 2, and can further extend air passage 10.

[0091] At this time, the fourth air guide plate 5 and the fifth air guide plate 6 can both be positioned in the retracted position so as not to provide significant resistance to the airflow. The first blade set 71 and the second blade set 72 can be specifically configured according to demand, for example, to realize a double-sided air blowing mode or to perform reciprocating oscillation.

[0092] In the cooling mode, the first air guide plate 2 can also swing back and forth within a certain range, and the second air guide plate 3 and the third air guide plate 4 can each rotate within the blowing area of the air outlet 10a to change the air direction, which gives users more choices and better meets the demand for differentiation.

[0093] This allows the area division control to realize the airflow angle and speed for cooling that meets the user's demand depending on the actual airflow area.

[0094] In some embodiments, the air conditioning indoor unit 100 has a heating mode, and as shown in Figures 12 to 14, in the heating mode, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 all guide air downward, blowing hot air onto the floor surface; since the hot air current has low density and rises upward, it can provide the user with a more comfortable heating experience and realize the function of "warm feet." For example, the first air guide plate 2, the second air guide plate 3, and the third air guide plate 4 are all arranged approximately vertically so as to be approximately perpendicular to the floor surface, thereby realizing downward air guidance.

[0095] In some examples, in heating mode, the first air guide plate 2 directs air downward, and the second and third air guide plates 2 and 4 swing independently to change the airflow direction, making it easier to blow air over longer distances to meet the airflow needs of users in different areas. In this case, the fourth and fifth air guide plates 5 and 6 can both direct air downward. For example, the fourth and fifth air guide plates 5 and 6 can both be arranged approximately vertically, or the fourth and fifth air guide plates 5 and 6 can swing independently to improve the airflow range and distance. The first and second blade sets 71 and 72 can be specifically configured according to demand, for example, to direct air forward, achieve a two-sided airflow mode, or swing back and forth. This allows for area division control to achieve the airflow angle and speed in a cooling state that meets the user's demand depending on the actual airflow area.

[0096] A control method for an air conditioning indoor unit 100 according to an embodiment of the present application will be described below with reference to the drawings. The air conditioning indoor unit 100 can be the air conditioning indoor unit 100 according to any of the above-described embodiments of the present application.

[0097] 4, the air outlet 10a has multiple air outlet regions 10f arranged in sequence along the longitudinal direction of the air conditioning indoor unit 100, and each air outlet region 10f is provided with one set of blades that can swing left and right to guide the air blown out of the corresponding air outlet region 10f, and the front region of the air conditioning indoor unit 100 includes multiple air blowing regions arranged in sequence along the longitudinal direction of the air conditioning indoor unit 100, each air outlet region 10f corresponding to one air blowing region, and the air conditioning indoor unit 100 can blow air towards the corresponding air blowing region via the air outlet region 10f. In the description of this application, "multiple" means two or more.

[0098] As shown in Figs. 24 to 26, the control method for the air conditioning indoor unit 100 includes the steps of detecting whether or not a target object is present in the front area of the air conditioning indoor unit 100, and, if a target object is present in the front area of the air conditioning indoor unit 100, controlling the corresponding blow-out area 10f to switch to windless blow-out air depending on the air-blowing area in which the target object is located. For example, the step determines the air-blowing area in which the target object is located, that is, determines which or which air-blowing area the target object is located in. For example, if there is one target object, the step determines which air-blowing area the target object is located in, and if there are multiple target objects, the step determines which air-blowing area each of the multiple target objects is located in. After making the determination, the method includes the steps of controlling the air outlet region 10f corresponding to the air outlet region where the target object is located to switch to windless air outlet, obtaining the distance between the target object and the air conditioning indoor unit 100 and comparing the obtained distance with a predetermined distance, and controlling the blade set corresponding to the air outlet region of the air conditioning indoor unit 100 where the target object is located to rotate based on the comparison result, i.e., controlling the state of the blade set based on the proximity of the target object to the air conditioning indoor unit 100 so that the state of the blade set matches the distance between the target object and the air conditioning indoor unit 100, thereby ensuring comfort regardless of the distance between the target object and the air conditioning indoor unit 100. In this regard, the front region of the air conditioning indoor unit 100 can be understood as the air outlet region of the air conditioning indoor unit 100.

[0099] In the present application, the order of the steps of "obtaining the distance between the target object and the air conditioning indoor unit 100" and "controlling the corresponding blowing area 10f to switch to windless blowing air depending on the air blowing area in which the target object is located" is not fixed.

[0100] Specifically, the "step of controlling the corresponding blowing area 10f to switch to windless blowing air depending on the blowing area where the target object is located" can be performed before the "step of acquiring the distance between the target object and the air conditioning indoor unit 100", and for example, the control method includes the steps of detecting whether or not the target object is present in the front area of the air conditioning indoor unit 100, and if present, first controlling the corresponding blowing area 10f to switch to windless blowing air depending on the blowing area where the target object is located, then acquiring the distance between the target object and the air conditioning indoor unit 100 and comparing the acquired distance with a predetermined distance, and controlling the corresponding blade group to rotate based on the comparison result. Alternatively, the "step of controlling the corresponding blowing area 10f to switch to windless-feeling blowing air depending on the blowing area where the target object is located" can be performed after the "step of acquiring the distance between the target object and the air conditioning indoor unit 100". For example, the control method includes the steps of detecting whether or not a target object is present in the front area of the air conditioning indoor unit 100, and if present, first acquiring the distance between the target object and the air conditioning indoor unit 100 and comparing the acquired distance with a predetermined distance, controlling the corresponding blade group to rotate based on the comparison result, and then controlling the corresponding blowing area 10f to switch to windless-feeling blowing air depending on the blowing area where the target object is located. In this step, the order of the "step of controlling the corresponding blade group to rotate based on the comparison result" and the "step of controlling the corresponding blowing area 10f to switch to windless-feeling blowing air depending on the blowing area where the target object is located" is not fixed. Alternatively, the "step of controlling the corresponding blowing area 10f to switch to windless blowing air depending on the blowing area in which the target object is located" and the "step of acquiring the distance between the target object and the air conditioning indoor unit 100" can be performed simultaneously.

[0101] In some embodiments, the target object is an individual user. For example, when detecting the presence of a target object in the front region of the air conditioning indoor unit 100, if there is one target object, and the target object is located in one of the multiple air-blowing regions, the air-blowing region 10f corresponding to the one air-blowing region is controlled to switch to windless airflow, thereby satisfying the target object's need for windless airflow and improving comfort. If there are multiple target objects, for example, if there are two target objects and the two target objects are located in different air-blowing regions, the air-blowing regions 10f corresponding to the two air-blowing regions are controlled to switch to windless airflow, thereby satisfying the multiple target objects' need for windless airflow simultaneously and ensuring comfort for the multiple target objects. Of course, there may be three or more target objects.

[0102] It can be understood that the number of blowing areas 10f and the number of air blowing areas are the same, and there may be a one-to-one correspondence between the multiple blowing areas 10f and the multiple air blowing areas, or there may be no direct relationship between the number of blowing areas 10f and the number of target objects, and the number of blowing areas 10f may be greater than, equal to, or less than the current number of target objects.

[0103] This further enriches the ventilation modes of the air conditioning indoor unit 100, realizing windless ventilation in the corresponding area according to the position of the target object, flexibly controlling the divided ventilation to achieve comfortable blowing air in the area, and controlling the rotation of the corresponding blade group to match the state of the blade group to the current position of the target object based on the distance between the target object and the air conditioning indoor unit 100, thereby further improving the comfort of the corresponding area and better meeting the demand for differentiation for different targets.

[0104] In some embodiments, a camera or a sensor (for example, a radar sensor) or the like is used to detect whether or not a target object is present in the front area of the air conditioning indoor unit 100, and the air-blowing area in which the target object is located is determined.

[0105] In some embodiments of the present application, the control method further includes a step of controlling the remaining air outlet areas 10f other than the corresponding air outlet area 10f based on the air outlet area where the target object is located to switch to normal air outlet, wherein the air outlet volume of the air outlet area 10f during normal air outlet is larger than the air outlet volume of the air outlet area 10f during calm air outlet, so that the air outlet volume of one air outlet area 10f during normal air outlet is relatively large, thereby enabling the ambient temperature of the corresponding air outlet area to be quickly adjusted. In other words, when no target object is present in one or some of the air outlet areas, all of the air outlet areas 10f corresponding to that air outlet area are switched to normal air outlet.

[0106] For example, when it is detected that a target object exists in the front region of the air conditioning indoor unit 100, if there is one target object, the target object is located in one of the multiple air flow regions, and in this case, the blowing region 10f corresponding to the one air flow region is switched to windless air flow, and the remaining air flow regions 10f are all controlled to be switched to normal air flow, so that the target object's demand for windless air flow is met, and the target object's demand for environmental temperature is better met and comfort is further improved. If there are multiple target objects, for example, taking an example where there are two target objects, and the two target objects are located in the same air flow region, the blowing region 10f corresponding to the air flow region in which the target object is located is controlled to be switched to normal air flow. The control unit 10 controls the blowing area 10f corresponding to the two blowing areas 10a to switch to windless airflow and the remaining blowing areas 10f to switch to normal airflow, and if two target objects are in different blowing areas, and the number of blowing areas 10f is greater than the number of target objects, the control unit 10 controls the blowing areas 10f corresponding to the two blowing areas 10a to switch to windless airflow and the remaining blowing areas 10f to switch to normal airflow, and if there are two blowing areas 10f, both of these two blowing areas 10f are switched to windless airflow, thereby better meeting the demands of multiple target objects for environmental temperature under the premise that the demands of multiple target objects for windless airflow are met simultaneously.

[0107] In some embodiments of the present application, as shown in FIG. 4, the plurality of blowing areas 10f are two blowing areas 10f, and the two blowing areas 10f are respectively a first blowing area 10g and a second blowing area 10h, and the plurality of air-blowing areas are two air-blowing areas, and the two air-blowing areas are respectively a first air-blowing area and a second air-blowing area, and among them, the first blowing area 10g corresponds to the first air-blowing area, and the second blowing area 10h corresponds to the second air-blowing area.

[0108] 25, the step of controlling the corresponding air outlet region 10f to switch to windless airflow depending on the air outlet region in which the target object is located includes the steps of: determining whether the target object is in the first air outlet region; if the answer is yes, i.e., if the target object is in the first air outlet region, controlling the first air outlet region 10g to switch to windless airflow to ensure the comfort of the target object; and if not, i.e., if the target object is not in the first air outlet region, indicating that the target object is in the second air outlet region, controlling the second air outlet region 10h to switch to windless airflow to ensure the comfort of the target object. This allows the air conditioning indoor unit 100 to have a simple structure, simple control logic, and is easy to implement.

[0109] Of course, the present application is not limited to this, and for example, the step of controlling the corresponding air outlet region 10f to switch to windless air outlet according to the air outlet region where the target object is located includes the steps of determining whether the target object is in the second air outlet region, and if so, controlling the second air outlet region 10h to switch to windless air outlet, and if not, indicating that the target object is in the first air outlet region, controlling the first air outlet region 10g to switch to windless air outlet. Of course, the number of air outlet regions 10f may be three or more.

[0110] In some embodiments of the present application, the air conditioning indoor unit 100 has a windless mode, and by executing the control method of the present application in the windless mode, if the user requires a windless effect, the air conditioning indoor unit 100 can be controlled to operate in the windless mode, and at this time, it is detected whether or not there is a target object in the front area of the air conditioning indoor unit 100, and if there is, it is determined that this is the air blowing area where the target object is located, and the blowing area 10f corresponding to the air blowing area where the target object is located is controlled to switch to windless blowing air.

[0111] It can be understood that when the air conditioning indoor unit 100 is in the windless mode, the air conditioning indoor unit 100 is capable of both cooling and heating. Of course, the air conditioning indoor unit 100 can have various other modes.

[0112] There may be one or more second air guide plates 3, and when there are multiple second air guide plates 3, the multiple second air guide plates 3 are arranged at intervals along the longitudinal direction of the air conditioning indoor unit 100, and each second air guide plate 3 is capable of rotating around the second pivot axis 3R. There may be one or more third air guide plates 4, and when there are multiple third air guide plates 4, it can be understood that the multiple third air guide plates 4 are arranged at intervals along the longitudinal direction of the air conditioning indoor unit 100, and each third air guide plate 4 is capable of rotating around the third pivot axis 4R.

[0113] In some embodiments of the present application, as shown in FIG. 4, the second air guide plate 3 is provided in one of the blowing areas 10f so as to be pivotable about the second pivot axis 3R, and the third air guide plate 4 is provided in the other blowing area 10f so as to be pivotable about the third pivot axis 4R, that is, the second air guide plate 3 and the third air guide plate 4 are provided in different blowing areas 10f, and the second pivot axis 3R and the third pivot axis 4R are both parallel to the longitudinal direction of the air conditioning indoor unit 100, and for example, the second pivot axis 3R coincides with the third pivot axis 4R. The air conditioning indoor unit 100 further includes a fourth air guide plate 5 and a fifth air guide plate 6, and if the fourth air guide plate 5 and the second air guide plate 3 are provided in the same blow-out region 10f and the fifth air guide plate 6 and the third air guide plate 4 are provided in the same blow-out region 10f, the fourth air guide plate 5 and the fifth air guide plate 6 are arranged at an interval along the longitudinal direction of the air conditioning indoor unit 100, both the fourth air guide plate 5 and the fifth air guide plate 6 extend along the longitudinal direction of the air conditioning indoor unit 100, and the fourth air guide plate 5 and the fifth air guide plate 6 are provided in different blow-out regions 10f. In this regard, the fourth pivot axis 5R is adjacent to one side of the second air guide plate 3 away from the first air guide plate 2, and the fifth pivot axis 6R is adjacent to one side of the third air guide plate 4 away from the first air guide plate 2. In the shielding position, the fourth air guide plate 5 is detached from the first accommodating groove 10d and shields a portion of the corresponding blowing area 10f, and the fifth air guide plate 6 is detached from the second accommodating groove 10e and shields a portion of the corresponding blowing area 10f.

[0114] The step of controlling the corresponding blowout region 10f to switch to windless-feeling blowout air includes the step of controlling the corresponding fourth air guide plate 5 and / or fifth air guide plate 6 to move to the blocking position, i.e., when there is one or more blowout regions 10f that need to be switched to windless-feeling blowout air, if the fourth air guide plate 5 corresponds to all of the blowout regions 10f, the corresponding fourth air guide plate 5 is controlled to move to the blocking position, if the fifth air guide plate 6 corresponds to all of the blowout regions 10f, the corresponding fifth air guide plate 6 is controlled to move to the blocking position, and when there are more than one blowout region 10f that need to be switched to windless-feeling blowout air, if some of the multiple blowout regions 10f correspond to the fourth air guide plate 5 and some correspond to the fifth air guide plate 6, the corresponding fourth air guide plate 5 and fifth air guide plate 6 are controlled to move to the blocking position. This achieves windless-feeling blowout air from the air outlet 10f, and the method is simple and easy to control.

[0115] Therefore, by configuring the first air guide plate 2, the second air guide plate 3, the third air guide plate 4, the fourth air guide plate 5 and the fifth air guide plate 6, it is possible to realize multi-angle and multi-mode air flow control of the air conditioning indoor unit 100, thereby better meeting the differentiated needs of different users.

[0116] It should be noted that there may be one or more fourth air guide plates 5, and when there are multiple fourth air guide plates 5, the multiple fourth air guide plates 5 can be arranged at intervals along the longitudinal direction of the air conditioning indoor unit 100, each of the fourth air guide plates 5 being rotatable about a fourth pivot axis 5R, and each fourth air guide plate 5 being installed to correspond to one second air guide plate 3. There may be one or more fifth air guide plates 6, and when there are multiple fifth air guide plates 6, the multiple fifth air guide plates 6 can be arranged at intervals along the longitudinal direction of the air conditioning indoor unit 100, each of the fifth air guide plates 6 being rotatable about a fifth pivot axis 6R, and each fifth air guide plate 6 being installed to correspond to one third air guide plate 4. The fourth pivot axis 5R and the fifth pivot axis 6R are both parallel to the longitudinal direction of the air conditioning indoor unit 100, for example, the fourth pivot axis 5R coincides with the fifth pivot axis 6R.

[0117] In the following, an example will be described in which the fourth air guide plate 5 moves to the blocking position to realize a windless blown air from the corresponding blowing area 10f. For example, as shown in Fig. 22, the second air guide plate 3 opens the blowing area 10f, the fourth air guide plate 5 is located at the blocking position, the second air guide plate 3 is close to the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, for example, the first air guide plate 2 is in contact with the edge of the fourth air guide plate 5 that is away from the fourth pivot axis 5R, the first air guide plate 2 opens the blowing port 10a, and one end of the first air guide plate 2 that is away from the first pivot axis 2R and the second air guide plate 3 are spaced apart. In this case, part of the air blown out corresponding to the air outlet region 10f of the second air guide plate 3 flows out through the fourth air guide plate 5, realizing a soft air blown out, and another part of the air blown out through the gap between the second air guide plate 3 and the first air guide plate 2, which is advantageous for improving the cooling / heating efficiency of the corresponding air outlet region 10f, and because the first air guide plate 2 opens the air outlet 10a, it is easy to ensure the cooling / heating efficiency of the other air outlet regions 10g.

[0118] For example, as shown in Figures 2 and 3, the housing 1 includes a chassis 11, a heat exchanger member 12, a fan wheel member 13, a surface frame 14, and a panel 15, the heat exchanger member 12, the fan wheel member 13, and the surface frame 14 are all attached to the chassis 11, the panel 15 is provided in front of the surface frame 14, the cross section of the heat exchanger member 12 is approximately U-shaped, the fan wheel member 13 is provided inside the heat exchanger member 12, the fan wheel member 13 can correspond to any of the multiple blowing areas 10f, and the fan wheel member 13 includes a cross-flow fan wheel.

[0119] When it is necessary to achieve windless blowing air in the blowing area 10f, if the air conditioning indoor unit 100 is in the cooling state, the first air guide plate 2, the second air guide plate 3 and the third air guide plate 4 can all be controlled according to the logic in the cooling mode of the air conditioning indoor unit 100, but this is not limited to this. For example, in the cooling mode, in the case of the first air guide plate 2, the tangential extension plane of the first air guide plate 2 and the second wall surface 10c of the air passage 10 substantially coincide with each other, and at this time, the cooperation of the upstream end of the first air guide plate 2 and the downstream end of the second wall surface 10c corresponds to extending the air passage 10, thereby effectively increasing the air blowing distance and achieving a good cooling effect. Alternatively, the first air guide plate 2 can also swing up and down around the first pivot axis 2R within a certain range, and in the case of the second air guide plate 3 and the third air guide plate 4, the second air guide plate 3 and the third air guide plate 4 can both be substantially parallel to the first air guide plate 2 and further extend the air passage 10. Alternatively, the second air guide plate 3 can swing up and down around the second pivot axis 3R, and the third air guide plate 4 can swing up and down around the third pivot axis 4R.

[0120] For example, in a cooling mode, the blade set can be rotated to a position that directs air forward, and can also oscillate back and forth from side to side about the axis of rotation.

[0121] In some embodiments of the present application, the step of controlling the remaining blowing areas 10f other than the corresponding blowing area 10f to switch to normal blowing air may include a step of controlling the corresponding fourth air guide plate 5 or fifth air guide plate 6 to move to a retracted position.

[0122] For example, in a step of controlling the corresponding blowing area 10f to switch to windless blowing air based on the blowing area in which the target object is located, and controlling the remaining blowing areas 10f other than the corresponding blowing area 10f to switch to normal blowing air, if the target object is within the blowing area corresponding to the fourth air guide plate 5, for example, the fourth air guide plate 5 is controlled to move to a shielding position, and the fifth air guide plate 6 is controlled to move to a retracted position, so that the blowing area 10f corresponding to the fifth air guide plate 6 realizes normal blowing air.

[0123] 10 and 16, when the second air guide plate 3 opens the air outlet 10f, the fourth air guide plate 5 is located at the retracted position, the first air guide plate 2 opens the air outlet 10a, and one end of the first air guide plate 2 away from the first pivot axis 2R is spaced apart from the second air guide plate 3, part of the air blown out from the second air guide plate 3 corresponding to the air outlet region 10f flows out through one side of the second air guide plate 3 facing away from the first air guide plate 2, and another part flows out through the gap between the second air guide plate 3 and the first air guide plate 2, which makes it easy to ensure the cooling / heating efficiency of the corresponding air outlet region 10f.

[0124] In some embodiments of the present application, the step of controlling the blade group corresponding to the airflow region where the target object is located to rotate includes the step of controlling the corresponding blade group to rotate to a predetermined position, as shown in Figures 25 and 26. This simplifies the control of the rotation of the blade group, which is advantageous for simplifying the control logic, reducing energy consumption, and saving resources while ensuring comfort.

[0125] Of course, the present application is not limited to this, and the step of controlling the blade group corresponding to the air blowing area where the target object is located to rotate further includes a step of controlling the corresponding blade group to oscillate back and forth within a predetermined range.

[0126] In some embodiments of the present application, as shown in FIG. 25, the step of controlling the corresponding blade set to rotate to a predetermined position based on the comparison result indicates that the target object is far from the air conditioning indoor unit 100 if the acquired distance L is greater than the predetermined distance L0, and controls the blade set corresponding to the air blowing area where the target object is located to rotate to a position that guides air forward, thereby preventing the air blown out from the air conditioning indoor unit 100 from blowing directly onto the target object and easing the temperature at the location where the target object is located, thereby ensuring comfort. and if the acquired distance L is less than a predetermined distance L0, i.e., L≦L0, it indicates that the target object is close to the air conditioning indoor unit 100, and controls the blade group corresponding to the air blowing area where the target object is located to rotate to a position that directs air away from the central plane 100a of the air conditioning indoor unit 100, so that the central plane 100a is perpendicular to the longitudinal direction of the air conditioning indoor unit 100, and in this case, the air blown out of the air conditioning indoor unit 100 is similarly prevented from blowing directly toward the target object, making it easy to ensure comfort. wherein distance L is the distance between the acquired target object and the air conditioning indoor unit 100.

[0127] In some embodiments, the predetermined distance L0 satisfies 3 m≦L0≦5 m, allowing the control method of the air conditioning indoor unit 100 to better adapt to different indoor spaces.

[0128] In the following, an example in which there are two blowout regions 10f and one or two target objects will be described, but after reading the following embodiments, those skilled in the art will easily understand embodiments in which there are three or more blowout regions 10f and three or more target objects. For example, if the two blowout regions 10f are the first blowout region 10g and the second blowout region 10h, and the two airflow regions are the first airflow region and the second airflow region, respectively, there may be two blade groups, a first blade group 71 provided in the first blowout region 10g and a second blade group 72 provided in the second airflow region 10h, and the central plane 100a is located between the first blade group 71 and the second blade group 72.

[0129] When there is one target object, or when multiple target objects are located in approximately the same position, as shown in FIG. 26, if the target object is located in the first air-blowing area and the distance between the target object and the air-conditioning indoor unit 100 is greater than a predetermined distance, the first blade set 71 is controlled to rotate to a position where it guides air forward, and at this time, there are no particular restrictions on the state of the second blade set 72. If the target object is located in the first air-blowing area and the distance between the target object and the air-conditioning indoor unit 100 is equal to or less than a predetermined distance, the first blade set 71 is controlled to rotate away from the central plane 100a. The state of the second blade set 72 is not particularly limited at this time, and rotating the first blade set 71 to a position where it guides air in a direction away from the central plane 100a can be understood as controlling the first blade set 71 to rotate to a position where it guides air leftward if the first blade set 71 is located to the left of the second blade set 72, and controlling the first blade set 71 to rotate to a position where it guides air rightward if the first blade set 71 is located to the right of the second blade set 72. Explanation of the case where the target is located in the second air blowing area will be omitted.

[0130] When there are two target objects, if the two target objects are located in the same air-blowing area, the operation is the same as when there is one target object, and if the first target object is located in the first air-blowing area and the second target object is located in the second air-blowing area, and (1) the distance between the first target object and the air-conditioning indoor unit 100 is greater than a predetermined distance and the distance between the second target object and the air-conditioning indoor unit 100 is greater than the predetermined distance, the first blade set 71 and the second blade set 72 are controlled to rotate to positions where they direct air forward, respectively, and (2) the distance between the first target object and the air-conditioning indoor unit 100 is less than the predetermined distance and if the distance between the second target object and the air conditioning indoor unit 100 is equal to or less than a predetermined distance, the first blade set 71 and the second blade set 72 are controlled to rotate to positions where they direct air away from the central plane 100a, respectively; (3) if the distance between the first target object and the air conditioning indoor unit 100 is greater than the predetermined distance and the distance between the second target object and the air conditioning indoor unit 100 is equal to or less than the predetermined distance, the first blade set 71 is controlled to rotate to a position where it directs air forward, and the second blade set 72 is controlled to rotate to a position where it directs air away from the central plane 100a.

[0131] In some embodiments, the predetermined position varies depending on the distance between the target object and the air conditioning indoor unit 100. For example, multiple distance intervals may be set in advance, with the predetermined distance being the upper limit endpoint of the longest distance interval among the multiple distance intervals, and the multiple distance intervals respectively corresponding to multiple different predetermined distances, with the larger the distance corresponding to the distance interval, the smaller the angle between the blade set and the position where it directs air forward when in the predetermined position. Conversely, the smaller the distance corresponding to the distance interval, the larger the angle between the blade set and the position where it directs air forward when in the predetermined position. In this case, the distance interval in which the target object and the air conditioning indoor unit 100 are located can be determined, and the corresponding blade set can be controlled to rotate to the predetermined position corresponding to the distance interval.

[0132] Of course, the present application is not limited to this, and in other embodiments, when the obtained distance L is equal to or less than a predetermined distance L0, i.e., when L≦L0, the predetermined position may be an extreme position where the blade group directs air in a direction away from the central plane 100a of the air conditioning indoor unit 100, that is, the blade group is rotated to a position where the included angle with the position where the blade group directs air forward is maximum.

[0133] In some embodiments of the present application, when it is detected that there is one target object, if the acquired distance L is greater than a predetermined distance L0, all of the blade sets are controlled to rotate to positions where they direct airflow forward, and if the acquired distance L is equal to or less than the predetermined distance L0, all of the blade sets are controlled to rotate to positions where they direct airflow away from the central plane 100a. This ensures that the air blown out from other air-blowing areas blows directly, and prevents the target object from being so far away from the air conditioning indoor unit 100 that it no longer feels cold or hot, effectively ensuring comfort at different distances to the target object.

[0134] In the following, an example in which there are two blow-out regions 10f will be described, and those skilled in the art will be able to easily understand the case in which there are three or more blow-out regions 10f after reading the following embodiment. As shown in Fig. 25, when it is detected that there is one target object, if the target object is located in the first air-blowing region and the distance between the target object and the air-conditioning indoor unit 100 is greater than a predetermined distance, the first blade set 71 and the second blade set 72 are controlled to rotate to positions in which they direct air forward, and if the target object is located in the first air-blowing region and the distance between the target object and the air-conditioning indoor unit 100 is equal to or less than the predetermined distance, the first blade set 71 and the second blade set 72 are controlled to move away from the center plane 100a. In this regard, rotating the first blade group 71 and the second blade group 72 to a position where they guide air in a direction away from the central plane 100a can be understood as controlling the first blade group 71 to rotate to a position where they guide air leftward if the first blade group 71 is located to the left of the second blade group 72, and controlling the first blade group 71 to rotate to a position where they guide air rightward if the first blade group 71 is located to the right of the second blade group 72.

The control device includes a determination module and a control module, wherein the determination module is used to detect whether a target object exists in the front area of the air conditioning indoor unit 100 and determine the air-blowing area in which the target object is located, the determination module is further used to acquire the distance between the target object and the air-conditioning indoor unit 100 and compare the acquired distance with a predetermined distance, the control module is used to control the corresponding air-blowing area 10f to switch to windless air-blowing based on the determination result of the determination module, the control module is used to control the rotation of the blade group corresponding to the air-blowing area in which the target object is located based on the determination result of the determination module for the air-blowing area in which the target object is located to switch to windless air-blowing, and the control module is used to control the rotation of the blade group corresponding to the air-blowing area in which the target object is located based on the determination result of the determination module for the air-blowing area in which the target object is located

[0138] In some embodiments, the control module is further used to control the remaining blowing areas 10f other than the corresponding blowing area 10f to switch to normal blowing air based on the determination result of the determination module, and for the same blowing area 10f, the blowing air volume during normal blowing air is greater than the blowing air volume during windless blowing air. In some embodiments, there are two blowing areas 10f and two blowing areas, and the control module is used to control the first blowing area 10g to switch to windless blowing air when it is determined that the target object is in the first blowing area, and to control the second blowing area 10h to switch to windless blowing air when it is determined that the target object is not in the first blowing area. In some embodiments, the control module stage is further used to control the corresponding blade group to rotate to a position where it directs air forward when the determining means determines that the distance acquired is greater than a predetermined distance, and to control the corresponding blade group to rotate to a position where it directs air away from the central plane 100a that is perpendicular to the longitudinal direction of the air conditioning indoor unit 100 when the determining means determines that the distance acquired is equal to or less than the predetermined distance.
