For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] The following describes a control method of the air conditioner indoor unit 100 according to an embodiment of the present application with reference to FIG1 to FIG8 .

[0048] 1, 2, and 3, a control method for an air conditioning indoor unit 100 according to an embodiment of the present application is provided, wherein the air conditioning indoor unit 100 includes: a housing 1 and an air guide assembly 3. The housing 1 is provided with a heat exchange air duct 11, and the housing 1 is also provided with an air inlet 12 and an air outlet 13 connected to the heat exchange air duct 11. When the air conditioning indoor unit 100 is in operation, air outside the housing 1 enters the heat exchange air duct 11 through the air inlet 12, exchanges heat with the indoor heat exchanger 2 inside the housing 1, and is then discharged into the room through the air outlet 13, thereby achieving the effect of regulating the indoor temperature.

[0049] The air guide assembly 3 is disposed at the air outlet 13 of the housing 1 . The air guide assembly 3 includes a first air guide member 31 and a second air guide member 32 . Both the first air guide member 31 and the second air guide member 32 are rotatably disposed on the housing 1 . The first air guide member 31 and the second air guide member 32 are both used to guide the air outlet direction of the air outlet 13. When the first air guide member 31 is used to guide the air-conditioned air outlet, the side of the first air guide member 31 facing the inside of the casing 1 is the air inlet end of the first air guide member 31, and the side facing the room is the air outlet end of the first air guide member 31; when the second air guide member 32 is used to guide the air-conditioned air outlet, the side of the second air guide member 32 facing the inside of the casing 1 is the air inlet end of the second air guide member 32, and the side facing the room is the air outlet end of the second air guide member 32; when the first air guide member 31 and the second air guide member 32 are both used to guide the air-conditioned air outlet, an air guiding channel 33 is defined between the first air guide member 31 and the second air guide member 32, and the opposite sides of the air guiding channel 33 are respectively connected to the heat exchange air duct 11 and the indoor environment. Under the guidance of the air guiding channel 33, the air outlet direction of the air guiding channel 33 is also the direction in which the air guiding channel 33 extends from the heat exchange air duct 11 side to the indoor side. When the air outlet direction of the air guide channel 33 needs to be adjusted, the air guide assembly 3 is driven to rotate relative to the housing 1 to adjust the relative position of the air guide channel 33 and the air outlet 13, thereby obtaining different air outlet directions.

[0050] It should also be noted that the air guide channel 33 can guide most of the fluid flowing out of the heat exchange air duct 11. In some embodiments, part of the fluid can also flow out from between the air guide component 3 and the inner wall of the air outlet 13. In some other embodiments, the first air guide 31 rotates until it partially fits against the inner wall of the air outlet 13, and the second air guide 32 also rotates until it partially fits against the inner wall of the air outlet 13, so that the air guide channel 33 can guide all of the fluid flowing out of the heat exchange air duct 11.

[0051] 2 , 3 and 8 , the control method includes: controlling at least one of the first air guide 31 and the second air guide 32 to rotate back and forth to switch the air guide assembly 3 between a first state and a second state, wherein in the first state, the distance between the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 is D1, and in the second state, the distance between the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 is D2, and D1>D2.

[0052] When the air guide assembly 3 switches from the first state to the second state, the air outlet end of at least one of the first air guide member 31 and the second air guide member 32 is controlled to rotate toward the other, so that the distance between the air outlet end of the first air guide member 31 and the air outlet end of the second air guide member 32 is reduced from D1 to D2.

[0053] When the air guide assembly 3 switches from the second state to the first state, the air outlet end of at least one of the first air guide member 31 and the second air guide member 32 is controlled to rotate in a direction away from the other, so that the distance between the air outlet end of the first air guide member 31 and the air outlet end of the second air guide member 32 increases from D2 to D1.

[0054] In the process of switching from the first state to the second state, the air outlet end of at least one of the first air guide member 31 and the second air guide member 32 rotates toward the other, that is, the air outlet end of the first air guide member 31 and the air outlet end of the second air guide member 32 approach each other, that is, in the process of switching from the first state to the second state, the opening of the air outlet end of the air guide channel 33 gradually shrinks.

[0055] On the contrary, in the process of switching from the second state to the first state, the air outlet end of at least one of the first air guide member 31 and the second air guide member 32 rotates in a direction away from the other, that is, the air outlet end of the first air guide member 31 and the air outlet end of the second air guide member 32 are away from each other, that is, in the process of switching from the second state to the first state, the opening of the air outlet end of the air guide channel 33 gradually increases.

[0056] It should also be noted that at least one of the first air guide member 31 and the second air guide member 32 rotates back and forth to switch between the first state and the second state. The first air guide member 31 may rotate back and forth, and the second air guide member 32 may be stationary relative to the casing 1 to achieve switching between the first state and the second state; the first air guide member 31 may be stationary relative to the casing 1, and the second air guide member 32 rotates back and forth to achieve switching between the first state and the second state; the first air guide member 31 may rotate back and forth, and the second air guide member 32 may also rotate back and forth at the same time to achieve switching between the first state and the second state.

[0057] According to the control method of the air conditioner indoor unit 100 of the embodiment of the present application, the first air guide member 31 and the second air guide member 32 can be controlled to switch back and forth between the first state and the second state. Relatively speaking, in the first state, the opening of the air outlet end of the air guide channel 33 is larger, which can be understood as the first state being "open" and the air outlet is relatively dispersed. In the second state, the opening of the air outlet end of the air guide channel 33 is smaller, which can be understood as the second state being "closed" and the air outlet is relatively concentrated. Therefore, the control method of the present application can drive the opening of the air outlet end of the air guide channel 33 to switch back and forth between the open and closed states, so that the air outlet area of ​​the air conditioner fluctuates, which is conducive to simulating natural wind and improving the comfort of the air conditioner air outlet.

[0058] In some specific embodiments, the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 are controlled to rotate toward each other to switch from the first state to the second state. The first air guide 31 and the second air guide 32 both rotate, thereby increasing the speed of switching from the first state to the second state.

[0059] In some embodiments, controlling the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 to rotate toward each other includes: controlling the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 to rotate toward each other at the same time; or first controlling the air outlet end of the first air guide 31 to rotate toward the air outlet end of the second air guide 32, and then controlling the air outlet end of the second air guide 32 to rotate toward the air outlet end of the first air guide 31; or first controlling the air outlet end of the second air guide 32 to rotate toward the air outlet end of the first air guide 31, and then controlling the air outlet end of the first air guide 31 to rotate toward the air outlet end of the second air guide 32. Regardless of the order in which the first air guide 31 and the second air guide 32 rotate, as long as the air outlet ends of the first air guide 31 and the second air guide 32 are rotated toward each other.

[0060] In some embodiments, in the second state, the distance between the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 is greater than 0.

[0061] Through the above technical solution, the air-conditioning indoor unit 100 can also discharge air through the air guide channel 33 in the second state, avoiding the situation where the air guide component 3 completely blocks the air outlet 13 from discharging air.

[0062] 2 , 3 and 4 , in some embodiments, before controlling the air guide assembly 3 to switch from the second state to the first state, the air guide assembly 3 is controlled to be in a wind sweeping state. In the wind sweeping state, the air guide assembly 3 is controlled to maintain the second state and the first air guide member 31 and the second air guide member 32 are controlled to rotate synchronously.

[0063] In other words, the control method described above switches the air guide assembly 3 from the "open" state to the "closed" state, then sweeps air in the "closed" state, returns to the "open" state after the sweeping is complete, and repeats the above movement. This sweeping of air avoids local overcooling, expands the air outlet range of the air conditioner, and improves the indoor temperature regulation effect of the air conditioner indoor unit 100.

[0064] In some embodiments, at the end of the wind sweeping state, that is, when the air guide assembly 3 is controlled to maintain the second state and the first air guide member 31 and the second air guide member 32 are controlled to rotate synchronously, the air outlet end of at least one of the first air guide member 31 and the second air guide member 32 is controlled to rotate away from the other so that the air guide assembly 3 is switched from the second state to the first state.

[0065] In some specific embodiments, at the end of the wind sweeping state, the position of the first air guide 31 is the same as the position of the first air guide 31 in the first state, and the air outlet end of the second air guide 32 is controlled to rotate away from the air outlet end of the first air guide 31, so that the air guide assembly 3 is switched from the second state to the first state.

[0066] In other specific embodiments, at the end of the wind sweeping state, the position of the second air guide member 32 is the same as the position of the second air guide member 32 in the first state, and the air outlet end of the first air guide member 31 is controlled to rotate away from the air outlet end of the second air guide member 32, so that the air guide assembly 3 is switched from the second state to the first state.

[0067] In some other specific embodiments, at the end of the wind sweeping state, the position of the first air guide 31 deviates from the position of the first air guide 31 in the first state, and at the end of the wind sweeping state, the position of the second air guide 32 deviates from the position of the second air guide 32 in the first state, and the air outlet end of any one of the first air guide 31 and the second air guide 32 is controlled to rotate away from the other so that the air guide assembly 3 switches from the second state to the first state.

[0068] 2 and 5 , in some embodiments, in the first state, at least one of the first air guide 31 and the second air guide 32 is parallel to the inner wall of the air outlet 13 .

[0069] It should be understood that the first air guide 31 and / or the second air guide 32 may be completely parallel to the inner wall of the air outlet 13, or there may be a certain angle between the first air guide 31 and / or the second air guide 32 and the inner wall of the air outlet 13 but they may be similar to parallel.

[0070] Through the above technical solution, the obstruction of the first air guide member 31 and the second air guide member 32 to the air outlet of the air conditioner in the first state is reduced, thereby reducing wind loss.

[0071] In some embodiments, the rotation axis of the first air guide 31 and the rotation axis of the second air guide 32 are parallel to or coincide with each other. Through the above technical solution, when the air outlet end of the first air guide 31 and / or the air outlet end of the second air guide 32 rotates, the distance between the air outlet end of the first air guide 31 and the air outlet end of the second air guide 32 keeps changing synchronously along the length direction of the first air guide 31, so that the air conditioning air outlet is more uniform along the length direction of the first air guide 31.

[0072] In other embodiments, the rotation axis of the first air guide 31 and the rotation axis of the second air guide 32 are both parallel to the length direction of the air outlet 13 .

[0073] Through the above technical solution, the length direction of the air outlet end of the air guide channel 33 is always parallel to the length direction of the air outlet 13, which is beneficial to reducing wind loss and increasing air output.

[0074] In some other embodiments, the rotation axis of the first air guide 31 and the rotation axis of the second air guide 32 coincide with each other and are parallel to the length direction of the air outlet 13 .

[0075] The above technical solution is beneficial to the installation of the first air guide member 31 and the second air guide member 32 , reduces the space occupied by the air guide assembly 3 , and improves the space utilization rate of the air conditioner indoor unit 100 .

[0076] With reference to Fig. 3, in some embodiments, the line connecting the two free endpoints of the cross section of the first air guide 31 is the first line L1, and the line connecting the two free endpoints of the cross section of the second air guide 32 is the second line L2, and the length of the first line L1 is greater than the length of the second line L2. It should be noted that the cross section herein refers to a cross section perpendicular to the length direction, and the two free endpoints of the cross section of the first air guide 31 refer to: the two endpoints that are farthest apart in the circumferential direction of the rotation of the first air guide 31. The two free endpoints of the cross section of the second air guide 32 refer to: the two endpoints that are farthest apart in the circumferential direction of the rotation of the second air guide 32.

[0077] In the above technical solution, the length of the first connecting line L1 is greater than the length of the second connecting line L2, which can be understood as the width of the first air guide 31 is greater than the width of the second air guide 32, that is, the contact area between the first air guide 31 and the air outlet of the air conditioner is larger, thereby improving the air guiding effect of the first air guide 31.

[0078] In some specific embodiments, the ratio of the lengths of the first line L1 to the second line L2 is 1-1.8.

[0079] Through the above technical solution, the length ratio of the first connecting line L1 and the second connecting line L2 is limited within a certain range, thereby avoiding the situation where the first air guide member 31 is too wide compared to the second air guide member 32, resulting in the second air guide member 32 having an unclear air guiding effect, thereby ensuring the air guiding effect of the first air guide member 31 and the second air guide member 32 cooperating with each other.

[0080] 4 and 7 , in other embodiments, the line connecting the two free end points of the cross section of the first air guide 31 is the first line L1, the line connecting the two free end points of the cross section of the second air guide 32 is the second line L2, and the length of the first line L1 is greater than the length of the second line L2.

[0081] The first air guide member 31 and the second air guide member 32 rotate around the same rotation axis so that the first air guide member 31 and the second air guide member 32 can rotate relative to each other, that is, the first air guide member 31 can be rotated to above the second air guide member 32. Because the width of the first air guide member 31 is larger, when the first air guide member 31 is located above the second air guide member 32, the first air guide member 31 can guide more air-conditioned air downward; the first air guide member 31 can also be rotated to below the second air guide member 32. When the first air guide member 31 is located below the second air guide member 32, the first air guide member 31 can guide more air-conditioned air upward.

[0082] 2 , 3 and 4 , in some embodiments, the air conditioner indoor unit 100 includes a cooling mode, in which the first air guide 31 is controlled to be below the second air guide 32 , and at least in the first state, the first air guide 31 is controlled to guide air downward and forward.

[0083] Through the above technical solution, in the cooling mode, the first air guide member 31 is located below the second air guide member 32, so that when the first air guide member 31 guides air upward and forward, more cold air can be guided upward to form a skylight-style air supply, thereby improving the cooling effect of the air-conditioning indoor unit 100. In this embodiment, the first air guide member 31 is controlled to guide air downward and forward in the first state, so that in the cooling state, the cold air can also be guided downward and blown directly toward the user to cool the user, thereby improving the practicality of the air-conditioning indoor unit 100.

[0084] In some further embodiments, the refrigeration mode includes a refrigeration sweeping mode, in which the step of controlling at least one of the first air guide 31 and the second air guide 32 to rotate back and forth to switch the air guide assembly 3 between the first state and the second state is performed, and before controlling the air guide assembly 3 to switch from the second state to the first state, the air guide assembly 3 is controlled to maintain the second state and the first air guide 31 and the second air guide 32 are controlled to rotate synchronously, and the first air guide 31 switches between the forward and upward air guiding and supplying state and the forward and downward air supplying state.

[0085] Through the above-mentioned cooling sweeping mode, the opening of the air outlet end of the air guide channel 33 can be driven to switch back and forth between an open and a closed state, so that the amount of cold air blown out by the air conditioner fluctuates, and the cold air can be swept in the up and down directions in the cooling mode, thereby accelerating the diffusion speed of the cold air in the room. Moreover, when sweeping the air, the air outlet end of the air guide channel 33 is maintained in a "closed" state, reducing the opening of the air outlet end of the air guide channel 33, concentrating the wind force, and improving the sweeping effect.

[0086] In some specific embodiments, when in cooling mode, the first air guide 31 is located below the second air guide 32. With reference to FIG2 , in the first state, the first air guide 31 is controlled to be arranged forward and downward. When switching from the first state to the second state, the first air guide 31 is controlled to rotate upward by θ1°, and the second air guide 32 is controlled to rotate downward by θ2°. With reference to FIG3 , at this moment, the first air guide 31 is still arranged forward and downward, and then the air guide assembly 3 is controlled to sweep the wind, that is, the first air guide 31 and the second air guide 32 are synchronously rotated upward by θ2° to complete the sweeping of the wind. With reference to FIG4 , at this moment, the first air guide 31 is arranged forward and upward. Then the first air guide 31 is controlled to rotate downward by θ1°+θ2° to return to the first state, and then the air guide assembly 3 is controlled to repeat the above-mentioned motion.

[0087] The value range of θ1° is 10° to 40°, the value range of θ2° is 10° to 40°, θ1° can be equal to θ2°, or θ1° can be greater than or less than θ2°.

[0088] Through the above technical solution, when the air-conditioning indoor unit 100 is in cooling mode, the air-conditioning air output fluctuates and the cold air is guided upwards when sweeping the air, so that the air-conditioning air outlet covers a larger area. In addition, the air outlet method provided in the embodiment of the present application makes the air-conditioning air outlet distribution more uniform, reducing the local wind feeling of overcooling.

[0089] 5, 6, and 7, in some embodiments, a line connecting the two free endpoints of the cross section of the first air guide 31 is a first line L1, a line connecting the two free endpoints of the cross section of the second air guide 32 is a second line L2, and the length of the first line L1 is greater than the length of the second line L2. The air conditioner indoor unit 100 includes a heating mode. In the heating mode, the first air guide 31 is controlled to be located above the second air guide 32.

[0090] Through the above technical solution, the air-conditioning indoor unit 100 can guide more hot air downward in the heating mode to form a carpet-style air supply, thereby improving the regulating effect of the hot air on the indoor temperature.

[0091] In some embodiments, the heating mode includes a heating sweeping mode, in which the step of controlling at least one of the first air guide 31 and the second air guide 32 to rotate back and forth to switch the air guide assembly 3 between the first state and the second state is performed. Before controlling the air guide assembly 3 to switch from the second state to the first state, the air guide assembly 3 is controlled to maintain the second state and the first air guide 31 and the second air guide 32 are controlled to rotate synchronously, and the second air guide 32 keeps supplying air forward and downward.

[0092] Through the above technical solution, when the air conditioner indoor unit 100 is in heating mode, the air outlet of the air conditioner fluctuates and the hot air is guided downward when sweeping the air, so that the air outlet coverage area of ​​the air conditioner is larger, thereby improving the regulating effect of the hot air on the indoor temperature.

[0093] In some specific embodiments, in the heating mode, the first air guide 31 is located above the second air guide 32. Referring to FIG5 , in the first state, the first air guide 31 is controlled to be set forward and downward. When switching from the first state to the second state, the first air guide 31 is controlled to rotate downward by θ3° and the second air guide 32 is controlled to rotate upward by θ4°. Referring to FIG6 , at this time, the first air guide 31 is still set forward and downward, and then the air guide assembly 3 is controlled to sweep the wind, that is, the first air guide 31 and the second air guide 32 are synchronously rotated downward by θ4° to complete the wind sweep. Referring to FIG7 , at this time, the first air guide 31 is set backward and downward. Then the first air guide 31 is controlled to rotate upward by θ3°+θ4° to return to the first state, and then the air guide assembly 3 is controlled to repeat the above movement.

[0094] The value range of θ3° is 10° to 40°, the value range of θ4° is 10° to 40°, θ3° can be equal to θ4°, or θ3° can be greater than or less than θ4°.

[0095] 5 , in some embodiments, in the heating mode, the second air guide 32 is controlled in the first state to fit the inner wall of the air outlet 13 to prevent the air-conditioning air from passing between the second air guide 32 and the inner wall of the air outlet 13 , so that the air guide channel 33 can guide more air-conditioning air.

[0096] According to an embodiment of the present application, an air conditioner indoor unit 100 includes a housing 1, an air guide assembly 3, and a control module. The housing 1 is provided with a heat exchange duct 11, which is connected to an air inlet 12 and an air outlet 13. When the air conditioner indoor unit 100 is in operation, air from outside the housing 1 enters the heat exchange duct 11 through the air inlet 12, exchanges heat with the indoor heat exchanger 2 inside the housing 1, and is then discharged into the room through the air outlet 13, thereby regulating the indoor temperature.

[0097] The air guide assembly 3 is disposed at the air outlet 13 of the housing 1 . The air guide assembly 3 includes a first air guide member 31 and a second air guide member 32 . Both the first air guide member 31 and the second air guide member 32 are rotatably disposed on the housing 1 . The first air guide member 31 and the second air guide member 32 are both used to guide the air outlet direction of the air outlet 13. When the first air guide member 31 is used to guide the air-conditioned air outlet, the side of the first air guide member 31 facing the inside of the casing 1 is the air inlet end of the first air guide member 31, and the side facing the room is the air outlet end of the first air guide member 31; when the second air guide member 32 is used to guide the air-conditioned air outlet, the side of the second air guide member 32 facing the inside of the casing 1 is the air inlet end of the second air guide member 32, and the side facing the room is the air outlet end of the second air guide member 32; when the first air guide member 31 and the second air guide member 32 are both used to guide the air-conditioned air outlet, an air guiding channel 33 is defined between the first air guide member 31 and the second air guide member 32, and the opposite sides of the air guiding channel 33 are respectively connected to the heat exchange air duct 11 and the indoor environment. Under the guidance of the air guiding channel 33, the air outlet direction of the air guiding channel 33 is also the direction in which the air guiding channel 33 extends from the heat exchange air duct 11 side to the indoor side. When the air outlet direction of the air guide channel 33 needs to be adjusted, the air guide assembly 3 is driven to rotate relative to the housing 1 to adjust the relative position of the air guide channel 33 and the air outlet 13, thereby obtaining different air outlet directions.

[0098] The control module is arranged in the housing 1, and is used to execute the control method in the above technical solution.

[0099] 2 , 3 and 4 , according to the air-conditioning indoor unit 100 of the embodiment of the present application, the first air guide member 31 and the second air guide member 32 can be controlled to switch back and forth between the first state and the second state, that is, the opening of the air outlet end of the air guide channel 33 can be driven to switch back and forth between an open and a closed state, so that the air outlet area of ​​the air conditioner fluctuates, which is conducive to simulating natural wind and improving the comfort of the air outlet of the air conditioner.

[0100] In some embodiments, the first air guide 31 and the second air guide 32 are both constructed as air guide plates.

[0101] In some specific embodiments, a first air guiding surface 311 is provided on the side of the first air guiding member 31 facing the rotation axis thereof. The first air guiding surface 311 is a plane. In some other embodiments, the first air guiding surface 311 may also be an arcuate surface.

[0102] In some specific embodiments, a second air guide surface 321 is provided on the side of the second air guide member 32 facing the rotation axis thereof. The second air guide surface 321 is a plane. In some other embodiments, the second air guide surface 321 may also be an arcuate surface.

[0103] In some embodiments, the line connecting the two free end points of the cross section of the first air guide 31 is the first line L1, the line connecting the two free end points of the cross section of the second air guide 32 is the second line L2, and the length of the first line L1 is greater than the length of the second line L2.

[0104] In the above technical solution, the length of the first connecting line L1 is greater than the length of the second connecting line L2, which can be understood as the width of the first air guide 31 is greater than the width of the second air guide 32, that is, the contact area between the first air guide 31 and the air outlet of the air conditioner is larger, thereby improving the air guiding effect of the first air guide 31.

[0105] In some specific embodiments, the ratio of the lengths of the first line L1 to the second line L2 is 1-1.8.

[0106] Through the above technical solution, the length ratio of the first connecting line L1 and the second connecting line L2 is limited within a certain range, thereby avoiding the situation where the first air guide member 31 is too wide compared to the second air guide member 32, resulting in the second air guide member 32 having an unclear air guiding effect, thereby ensuring the air guiding effect of the first air guide member 31 and the second air guide member 32 cooperating with each other.

[0107] 2 , 3 and 4 , in some embodiments, the first air guide 31 is provided with a plurality of louvers 4 arranged at intervals, and the louvers 4 on the first air guide 31 can further guide the direction of the air outlet of the air conditioner.

[0108] In some specific embodiments, the louvers 4 are disposed on the side of the first air guide 31 facing the rotation axis, that is, the louvers 4 are located within the air guide channel 33, which can disperse the airflow of the air conditioner to a certain extent and reduce the sense of wind. The louvers 4 are spaced apart along the length of the first air guide 31, and the louvers 4 can swing along the length of the first air guide 31, that is, the louvers 4 can adjust the airflow of the air conditioner along the length of the first air guide 31.

[0109] In some specific embodiments, the air conditioner indoor unit 100 is a wall-mounted indoor unit, and the length direction of the first air guide 31 is parallel to the left-right direction of the air conditioner indoor unit 100. That is, the first air guide 31 and the second air guide 32 rotate relative to the housing 1 to adjust the air flow in the vertical direction, and the louver 4 swings along the length direction of the first air guide 31 to adjust the air flow in the left-right direction.

[0110] 1 , in some embodiments, the air guide assembly 3 has a closed state, in which the first air guide member 31 and the second air guide member 32 cooperate to block the air outlet 13 .

[0111] In the above technical solution, the air outlet 13 can be blocked by the cooperation of the first air guide member 31 and the second air guide member 32. On the one hand, it can reduce the entry of external impurities into the air duct through the air outlet 13. On the other hand, it can block the internal structure of the casing 1 and improve the aesthetics of the air-conditioning indoor unit 100.

[0112] In some specific embodiments, in the closed state, the mating sections of the first air guide 31 and the second air guide 32 are staggered in the front-to-back direction to block the gap between the first air guide 31 and the second air guide 32, thereby improving the appearance of the air conditioner indoor unit 100 when it is turned off.

[0113] Of course, in other embodiments, the air outlet 13 may be covered by another cover. When the air-conditioning indoor unit 100 is started, the cover can move to avoid the air outlet 13. When the air-conditioning indoor unit 100 is shut down, the cover can move to block the air outlet 13 and the air guide assembly 3.
