[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0037] Combination Figures 1 to 4 As shown, an embodiment of the present disclosure provides an internal air guide assembly for an air-conditioning indoor unit, wherein the air-conditioning indoor unit includes a shell 100, an air outlet 110 is provided at the lower portion of the shell 100, an air outlet duct 120 connected to the air outlet 110 is provided inside the shell 100, and the internal air guide assembly for the air-conditioning indoor unit is arranged in the air outlet duct 120. The internal wind guide assembly for the indoor unit of the air conditioner includes a first wind guide plate 210 and a second wind guide plate 220; wherein, a plurality of first air outlets are spaced apart along the width direction of the first wind guide plate 210, and the first wind guide plate 210 has a first central axis extending along its own length direction; a plurality of second air outlets are spaced apart along the width direction of the second wind guide plate 220, and the second wind guide plate 220 has a second central axis extending along its own length direction; the internal wind guide assembly for the indoor unit of the air conditioner can be controlled to switch between at least a first wind guide state and a second wind guide state; in the first wind guide state, the first wind guide plate 210 is parallel to the second wind guide plate 220, and is spaced apart along the height direction of the air outlet duct; when switched to the second wind guide state, the first wind guide plate 210 rotates around the first central axis along the first direction, and the second wind guide plate 220 rotates around the second central axis, so that the first wind guide plate 210 and the second wind guide plate 220 are connected; wherein the first direction and the second direction have opposite rotation directions.

[0038] Optionally, an air outlet 110 is provided at the lower part of the housing 100, a heat exchanger and a fan are provided inside the housing 100, and an air outlet duct 120 connected to the air outlet 110 is defined inside the housing 100. In this way, driven by the fan, after the indoor airflow enters the housing 100, it first flows through the heat exchanger and exchanges heat with the heat exchanger, and the airflow after the heat exchange with the heat exchanger flows to the air outlet 110 through the air outlet duct 120, and further flows back to the room through the air outlet 110 to adjust the temperature of the indoor environment.

[0039] Optionally, an outer air guide plate is provided at the air outlet 110 , and the outer air guide plate is used to open or close the air outlet 110 , or to guide the outlet airflow passing through the air outlet 110 when the air outlet 110 is opened.

[0040] Optionally, the first air outlet extends along the length direction of the first air guide plate 210, and the second air outlet extends along the length direction of the second air guide plate 220. In this way, the air output of the first air guide plate 210 and the second air guide plate 220 is guaranteed.

[0041] Optionally, in the second wind guiding state, the first wind guide plate 210 is bent in a direction away from the air outlet to form an arc-shaped wind guide plate, and the second wind guide plate 220 is bent in a direction toward the air outlet to form an arc-shaped wind guide plate. In this way, by making the first wind guide plate 210 and the second wind guide plate 220 rotate in the first direction and the second direction respectively, the first wind guiding state can be switched to the second wind guiding state, so that the first wind guide plate 210 and the second wind guide plate 220 are bent in different directions. When the outlet airflow hits the first wind guide plate 210 and the second wind guide plate 220, the outlet airflow can be dispersed and guided in different directions, so that the outlet directions of the multiple first air outlets and the multiple second air outlets can be different, thereby forming multiple outlet airflows with slightly different outlet directions. In this way, when the outlet airflow is dispersed by the internal wind guide component, turbulence can also be formed between the multiple airflows, thereby improving the comfort of the outlet airflow.

[0042] Furthermore, when the first air guide plate 210 and the second air guide plate 220 rotate in the second direction and the first direction respectively, they can switch from the second air guide state to the first air guide state to achieve normal air outlet.

[0043] Optionally, the internal air guide assembly for the air conditioner indoor unit also includes a first rotating shaft 410 and a second rotating shaft 420; the first rotating shaft 410 extends along the first central axis and is arranged at both ends of the first air guide plate 210, and the rotation of the first rotating shaft 410 drives the rotation of the first air guide plate 210; similarly, the second rotating shaft 420 extends along the second central axis and is arranged at both ends of the second air guide plate 220, and the rotation of the second rotating shaft 420 drives the rotation of the second air guide plate 220, thereby realizing the parallelism or docking of the first air guide plate 210 and the second air guide plate 220.

[0044] By using the internal air guide assembly for the indoor unit of the air conditioner provided by the embodiment of the present disclosure, when the indoor unit of the air conditioner is running, the first air guide plate 210 and the second air guide plate 220 can be respectively rotated along the first central axis and the second central axis thereof, thereby switching to the first air guide state. At this time, the first air guide plate 210 and the second air guide plate 220 are arranged at intervals along the height direction of the air outlet duct, so that while achieving conventional air outlet, the air outlet air flow can be decelerated to a certain extent, thereby improving the comfort of air outlet; or the first air guide plate 210 can be rotated along the first central axis in the first direction, and the second air guide plate 220 can be rotated around the second rotating shaft, thereby switching to the second air guide state, so that the adjacent end edges of the first air guide plate 210 and the second air guide plate 220 are connected, and at this time, the air flow in the air outlet duct can be blown outward from the first air outlet and the second air outlet, so that the air outlet air flow is dispersed by the first air outlet and the second air outlet, and the wind speed of the air outlet air flow is reduced and becomes softer, so that the user cannot feel the wind, thereby achieving a windless air outlet effect and improving the comfort.

[0045] Optionally, the inner air guide assembly further includes a first spoiler 510. The first spoiler 510 is disposed on a first windward side of the first air outlet and is disposed at a first angle with the first air guide plate 210 to form a first air guide outlet 310 with a first leeward side of the first air outlet; in the second air guide state, the first windward side faces the incoming flow direction of the airflow in the air outlet duct.

[0046] In this way, when the inner air guiding component is in the second air guiding state, through the setting of the first spoiler 510, multiple first air outlets can form first air guide outlets 310 that are staggered in sequence up and down along the flow direction of the outlet air flow, so that the multiple airflows blown out from the multiple first air guide outlets 310 have different wind speeds and frequencies. The multiple airflows are then mixed to reduce the wind speed, flow direction and turbulence, which not only makes the outlet air softer, but also reduces the outlet air noise and improves comfort.

[0047] Optionally, a plurality of first air outlets are arranged at intervals along the length direction of the first air guide plate 210; and the first spoiler 510 is arranged corresponding to the first air outlet.

[0048] In this way, the first air outlets are not only arranged in plurality along the width direction of the first air guide plate 210, but also arranged in plurality along the length direction of the first air guide plate 210. At the same time, a plurality of first spoilers 510 are arranged corresponding to the first air outlets, thereby forming a plurality of first air guide outlets 310 to improve the comfort of the outlet airflow.

[0049] Optionally, the first spoiler 510 is connected to the first air guide plate 210 with a rounded transition to reduce stress concentration, thereby improving the connection strength between the first spoiler 510 and the first air guide plate 210 .

[0050] Optionally, first connecting plates are provided at left and right ends of the first spoiler 510 to connect the first spoiler 510 and the first air guide plate 210 , so as to improve the stability of the first spoiler 510 .

[0051] Optionally, the side end of the first spoiler 510 corresponding to the first leeward side may have a certain elasticity. In this way, under the action of the airflow, this side end may be elastically deformed to change the direction of the outlet airflow again, thereby increasing the turbulence of the mixed outlet airflow and improving the comfort of the outlet airflow.

[0052] Optionally, the first angle is greater than or equal to 15° and less than or equal to 75°.

[0053] The angle of the first angle should not be too small. If the angle of the first angle is too small, that is, the opening is very small, the first spoiler 510 will seriously block the first air outlet, and the air volume of the outlet air flow dispersed by the first guide port 310 will become very small, which will seriously affect the spoiler effect of the inner air guide component on the outlet air flow and reduce the softness of the outlet air flow; at the same time, the angle of the first angle should not be too large. If the angle of the first angle is too large, that is, the opening is very large, the first spoiler 510 will seriously block the air flow dispersed by the adjacent first spoiler 510 and reduce the softness of the outlet air flow.

[0054] Optionally, the first angle is equal to 30°, 45°, 60°, etc.

[0055] Optionally, the first spoiler 510 includes a first side surface and a second side surface that are oppositely arranged, and the first side surface and / or the second side surface is a wavy surface.

[0056] Optionally, the first side surface is the side surface facing the first air outlet, and the second side surface is the side surface away from the first air outlet. The wave surface has multiple crests and troughs, which can break up the airflow passing through the first spoiler 510 into finer pieces, thereby improving the effect of spoiling the airflow; at the same time, it can also avoid the large wind resistance and airflow noise caused by the spoiler effect of the first spoiler 510.

[0057] Optionally, first connecting side plates are provided at both ends of the first spoiler 510, and the first connecting side plates are fixedly connected to corresponding edges of the first air outlet.

[0058] The first connecting side plate is fixedly connected to both ends of the first spoiler 510. By setting the first connecting side plate, a slit-shaped air outlet can be defined between the first spoiler 510 and the first air guide plate 210 to facilitate the outlet of the airflow. In addition, by setting the first connecting side plate, the stability of the connection between the first spoiler 510 and the first air guide plate 210 can be improved, and the first spoiler 510 can be prevented from being broken or damaged under the action of the airflow.

[0059] Optionally, the inner air guide assembly further includes a second spoiler 520. The second spoiler 520 is disposed on the second leeward side of the second air outlet and is disposed at a second angle with the second air guide plate 220 to form a second air guide outlet with the second windward side of the second air outlet; in the second air guide state, the second windward side faces the incoming flow direction of the airflow in the air outlet duct.

[0060] In this way, when the inner air guide component is in the docking state, through the setting of the second spoiler 520, multiple second air outlets can form second guide outlets 320 that are staggered in sequence up and down along the flow direction of the outlet air flow, so that multiple airflows blown out from the multiple second guide outlets 320 have different wind speeds and frequencies. The multiple airflows are then mixed to reduce the wind speed, flow direction and turbulence, which not only makes the outlet air softer, but also reduces the outlet air noise and improves comfort.

[0061] In addition, the first spoiler 510 and the second spoiler 520 have different orientations. The outlet airflow flowing through the first air guide plate 210 flows out of the first air guide plate 210 from the first air guide port 310, and the outlet airflow flowing through the second air guide plate 220 flows into the second air guide plate 220 from the second air guide port 320. In this way, the airflow flowing through the first air guide plate 210 and the airflow flowing through the second air guide plate 220 can form different flow directions and flow speeds, and can be further softened after mixing.

[0062] Optionally, a plurality of second air outlets are arranged at intervals along the length direction of the second air guide plate 220; and the second spoiler 520 is arranged corresponding to the second air outlet.

[0063] In this way, the second air outlets are not only arranged in plurality along the width direction of the first air guide plate 210, but also arranged in plurality along the length direction of the second air guide plate 220. At the same time, a plurality of second spoilers 520 are arranged corresponding to the second air outlets, thereby forming a plurality of second air guide outlets 320 to improve the comfort of the outlet airflow.

[0064] Optionally, the second spoiler 520 is connected to the second air guide plate 220 with a rounded transition to reduce stress concentration, thereby improving the connection strength between the second spoiler 520 and the second air guide plate 220 .

[0065] Optionally, first connecting plates are provided at left and right ends of the second spoiler 520 to connect the second spoiler 520 and the second wind guide plate 220 , so as to improve the stability of the second spoiler 520 .

[0066] Optionally, the side end of the second spoiler 520 corresponding to the second windward side may have a certain elasticity. In this way, under the action of the airflow, this side end may be elastically deformed to change the direction of the outlet airflow again, thereby increasing the turbulence of the mixed outlet airflow and improving the comfort of the outlet airflow.

[0067] Optionally, the second angle is greater than or equal to 15° and less than or equal to 75°.

[0068] The angle of the second angle should not be too small. If the angle of the second angle is too small, that is, the opening is very small, the second spoiler 520 will seriously block the second air outlet, and the air volume of the outlet air flow dispersed by the second guide port 320 will become very small, which will seriously affect the spoiler effect of the inner air guide component on the outlet air flow and reduce the softness of the outlet air flow; at the same time, the angle of the second angle should not be too large. If the angle of the second angle is too large, that is, the opening is very large, the second spoiler 520 will seriously block the airflow dispersed by the adjacent second spoiler 520 and reduce the softness of the outlet air flow.

[0069] Optionally, the second angle is equal to 30°, 45°, 60°, etc.

[0070] Optionally, the second spoiler 520 includes a third side surface and a fourth side surface that are oppositely arranged, and the third side surface and / or the fourth side surface is a wavy surface.

[0071] Optionally, the third side surface is the side surface facing the second air outlet, and the fourth side surface is the side surface away from the second air outlet. The wave surface has multiple crests and troughs, which can break up the airflow passing through the second spoiler 520 into finer pieces, thereby improving the effect of spoiling the airflow; at the same time, it can also avoid the large wind resistance and airflow noise caused by the spoiling effect of the second spoiler 520.

[0072] Optionally, second connecting side plates are provided at both ends of the second spoiler 520, and the second connecting side plates are fixedly connected to corresponding edges of the second air outlet.

[0073] The second connecting side plate is fixedly connected to both ends of the second spoiler 520. By setting the second connecting side plate, a slit-shaped air outlet can be defined between the second spoiler 520 and the second air guide plate 220 to facilitate the outlet of the airflow. In addition, by setting the second connecting side plate, the stability of the connection between the second spoiler 520 and the second air guide plate 220 can be improved, and the second spoiler 520 can be prevented from being broken or damaged under the action of the outlet airflow.

[0074] Optionally, the inner air guide assembly also includes: a first motor, which is driven and connected to the first air guide plate 210, and is used to drive the first air guide plate 210 to rotate along the first central axis; a second motor, which is driven and connected to the second air guide plate 220, and is used to drive the second air guide plate 220 to rotate along the second central axis.

[0075] By setting the first motor and the second motor, the first air guide plate 210 and the second air guide plate 220 can be driven separately, so that the first air guide plate 210 is driven by the first rotating shaft 410 and the second air guide plate 220 is driven by the second rotating shaft 420 to form different rotation directions, thereby switching the internal air guide component used for the air conditioner indoor unit freely between the overlapping state and the docking state.

[0076] Optionally, the first air guide plate 210 can also be driven by the first motor to switch to any other angle that does not contact the air duct wall of the air outlet duct 120, and the second air guide plate 220 can also be driven by the second motor to switch to any other angle that does not contact the air duct wall of the air outlet duct 120, thereby achieving dispersion of the outlet airflow.

[0077] Optionally, the surface of the first air guide plate 210 is coated with an air purification coating; and / or the surface of the second air guide plate 220 is coated with an air purification coating.

[0078] In this way, the first air guide plate 210 and / or the second air guide plate 220 can increase the air purification function, so that the air flow passing through the first air guide plate 210 and / or the second air guide plate 220 can be purified to a certain extent, thereby improving the cleanliness of the air flow and the comfort of the user.

[0079] Optionally, the first air guide plate 210 and / or the second air guide plate 220 itself may also have a purification function, that is, when the first air guide plate 210 and / or the second air guide plate 220 are produced, raw materials containing purification materials are mixed into the production materials of the first air guide plate 210 and / or the second air guide plate 220. In this way, the first air guide plate 210 and / or the second air guide plate 220 after molding itself can have a purification function, thereby purifying the outlet airflow passing through the first air guide plate 210 and / or the second air guide plate 220.

[0080] Optionally, the surface of the first spoiler 510 is coated with an air purification coating; and / or, the surface of the first spoiler 510 is coated with an air purification coating.
