[0039] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides an internal air guide assembly for an indoor unit of an air conditioner, wherein the indoor unit of the air conditioner comprises a housing 100, an air outlet 110 is provided at the lower portion of the housing 100, and an air outlet duct 120 connected to the air outlet 110 is provided inside the housing 100. The internal air guide assembly for the indoor unit of the air conditioner is arranged in the air outlet duct 120, and comprises a first air guide plate 210, a second air guide plate 220, a first rotating shaft 310, and a second rotating shaft 320. Among them, the first air guide plate 210 is provided with a plurality of first air outlets spaced apart along its width direction; the second air guide plate 220 is provided with a plurality of second air outlets spaced apart along its width direction; the first rotating shaft 310 extends along the length direction of the first air guide plate 210 and is arranged close to the upper air duct plate of the air outlet duct 120, and the projection of the first rotating shaft 310 on the first air guide plate 210 extends with the center line of the first air guide plate 210; the second rotating shaft 320 extends along the length direction of the second air guide plate 220 and is arranged close to the lower air duct plate of the air outlet duct 120, and the projection of the second rotating shaft 320 on the second air guide plate 220 extends with the center line of the second air guide plate 220. The inner air guide assembly can be switched between an overlapping state and a docking state in a controlled manner; in the overlapping state, the first air guide plate 210 and the second air guide plate 220 are stacked; when switched to the docking state, the first air guide plate 210 rotates along a first direction around the first rotating shaft 310, and the second air guide plate 220 rotates around the second rotating shaft 320, so that the first air guide plate 210 and the second air guide plate 220 are docked; wherein the first direction and the second direction have opposite rotation directions.

[0040] 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.

[0041] 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 air flow passing through the air outlet 110 when the air outlet 110 is opened.

[0042] 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.

[0043] Optionally, in the overlapping state, the first air guide plate 210 is bent toward the direction close to the first rotating shaft 310 to form an arc-shaped air guide plate, and the second air guide plate 220 is bent toward the direction away from the second rotating shaft 320 to form an arc-shaped air guide plate. In this way, when the outlet airflow hits the first air guide plate 210 and the second air 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 inner air guide component, turbulence can be formed between the multiple airflows, thereby improving the comfort of the outlet airflow.

[0044] Optionally, the first rotating shaft 310 is fixedly connected to the first air guide plate 210, the first rotating shaft 310 extends along the length direction of the first air guide plate 210 and is arranged close to the upper air duct plate of the air outlet duct 120, and the projection of the first rotating shaft 310 on the first air guide plate 210 extends along the center line of the first air guide plate 210; the second rotating shaft 320 is fixedly connected to the second air guide plate 220, the second rotating shaft 320 extends along the length direction of the second air guide plate 220 and is arranged close to the lower air duct plate of the air outlet duct 120, and the projection of the second rotating shaft 320 on the second air guide plate 220 extends along the center line of the second air guide plate 220. In this way, driven by the first rotating shaft 310 and the second rotating shaft 320, the first air guide plate 210 and the second air guide plate 220 can overlap in the air outlet duct 120 to form a stacked state, so that the air conditioner indoor unit can achieve normal air outlet; or, the adjacent end edges of the first air guide plate 210 and the second air guide plate 220 can be docked to achieve dispersion of the outlet airflow.

[0045] Optionally, the first rotating shaft is fixedly connected to the first air guide plate 210 via a connecting rod or a fixing plate to improve structural stability; similarly, the second rotating shaft is fixedly connected to the second air guide plate 220 via a connecting rod or a fixing plate to improve structural stability.

[0046] By using the internal air guide assembly for the indoor unit of the air conditioner provided in 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 switched to overlap so that the two are superimposed, and normal air outlet can be achieved at this time; by arranging an upper air duct plate close to the air outlet duct 120, and the projection of the first rotating shaft 310 on the first air guide plate 210 coincides with the center line of the first air guide plate 210, and a lower air duct plate close to the air outlet duct 120, and the projection of the second air guide plate 220 coincides with the center line of the second air guide plate 220 If the lines overlap, the first air guide plate 210 can be controlled to rotate around the first rotating shaft 310 in the first direction, and the second air guide plate 220 can be controlled to rotate around the second rotating shaft 320, so that the adjacent end edges of the first air guide plate 210 and the second air guide plate 220 are connected. At this time, the air flow in the air outlet duct 120 can be blown out from the first air outlet and the second air outlet. In this way, the outlet air flow is broken up by the first air outlet and the second air outlet, and the wind speed of the 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 comfort.

[0047] Optionally, the inner air guide assembly further includes a first air guide plate 410. The first air guide plate 410 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 610 with a first leeward side of the first air outlet; in the docking state, the first windward side faces the incoming flow direction of the airflow in the air outlet duct 120.

[0048] In this way, when the inner air guide component is in the docking state, through the setting of the first guide plate 410, multiple first air outlets can form first guide outlets 610 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 guide outlets 610 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.

[0049] 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 air guide plate 410 is arranged corresponding to the first air outlets.

[0050] 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 guide plates 410 are arranged corresponding to the first air outlets, thereby forming a plurality of first guide outlets 610 to improve the comfort of the outlet airflow.

[0051] Optionally, the first guide plate 410 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 guide plate 410 and the first air guide plate 210 .

[0052] Optionally, first connecting plates are provided at left and right ends of the first guide plate 410 to connect the first guide plate 410 and the first air guide plate 210 , so as to improve the stability of the first guide plate 410 .

[0053] Optionally, the side end of the first guide plate 410 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.

[0054] Optionally, the first angle is greater than or equal to 15° and less than or equal to 75°.

[0055] 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 guide plate 410 will seriously block the first air outlet, and the air volume of the outlet airflow dispersed by the first guide port 610 will become very small, which will seriously affect the turbulence effect of the inner air guide component on the outlet airflow and reduce the softness of the outlet airflow; 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 guide plate 410 will seriously block the airflow dispersed by the adjacent first guide plate 410 and reduce the softness of the outlet airflow.

[0056] Optionally, the first angle is equal to 30°, 45°, 60°, etc.

[0057] Optionally, the inner air guide assembly further includes a second air guide plate 420. The second air guide plate 420 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 620 with the second windward side of the second air outlet; in the docking state, the second windward side faces the incoming flow direction of the airflow in the air outlet duct 120.

[0058] In this way, when the inner air guide component is in the docking state, through the setting of the second guide plate 420, multiple second air outlets can form second guide outlets 620 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 620 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.

[0059] In addition, the first guide plate 410 and the second guide plate 420 have different orientations. The outlet airflow flowing through the first guide plate 210 flows out of the first guide plate 210 from the first guide port 610, and the outlet airflow flowing through the second guide plate 220 flows into the second guide plate 220 from the second guide port 620. In this way, the airflow flowing through the first guide plate 210 and the airflow flowing through the second guide plate 220 can form different flow directions and flow speeds, and can be further softened after mixing.

[0060] 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 air guide plate 420 is arranged corresponding to the second air outlets.

[0061] 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 guide plates 420 are arranged corresponding to the second air outlets, thereby forming a plurality of second guide outlets 620 to improve the comfort of the outlet airflow.

[0062] Optionally, the second guide plate 420 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 guide plate 420 and the second air guide plate 220 .

[0063] Optionally, first connecting plates are provided at left and right ends of the second guide plate 420 to connect the second guide plate 420 and the first guide plate 220 , thereby improving the stability of the second guide plate 420 .

[0064] Optionally, the side end of the second guide plate 410 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.

[0065] Optionally, the second angle is greater than or equal to 15° and less than or equal to 75°.

[0066] 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 guide plate 420 will seriously block the second air outlet, and the air volume of the outlet airflow dispersed by the second guide outlet 620 will become very small, which will seriously affect the turbulence effect of the inner air guide component on the outlet airflow and reduce the softness of the outlet airflow; 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 guide plate 420 will seriously block the airflow dispersed by the adjacent second guide plate 420 and reduce the softness of the outlet airflow.

[0067] Optionally, the second angle is equal to 30°, 45°, 60°, etc.

[0068] Optionally, the inner air guide assembly further includes a first motor and a second motor. The output shaft of the first motor is drivingly connected to the first rotating shaft 310, and is used to drive the first rotating shaft 310 to rotate so as to drive the first air guide plate 210 to rotate; the output shaft of the second motor is drivingly connected to the second rotating shaft 320, and is used to drive the second rotating shaft 320 to rotate so as to drive the second air guide plate 220 to rotate.

[0069] 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 310 and the second air guide plate 220 is driven by the second rotating shaft 320 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] Optionally, the surface of the first guide plate 410 is coated with an air purification coating; and / or the surface of the second guide plate 420 is coated with an air purification coating.

[0075] In this way, the first guide plate 410 and / or the second guide plate 420 can increase the air purification function, so that the airflow passing through the first guide plate 410 and / or the second guide plate 420 can be purified to a certain extent, thereby improving the cleanliness of the airflow and the comfort of the user.

[0076] Optionally, the first guide plate 410 and / or the second guide plate 420 itself may also have a purification function, that is, when the first guide plate 410 and / or the second guide plate 420 are produced, raw materials containing purification materials are mixed into the production materials of the first guide plate 410 and / or the second guide plate 420, so that the first guide plate 410 and / or the second guide plate 420 after molding itself can have a purification function, thereby purifying the outlet airflow passing through the first guide plate 410 and / or the second guide plate 420.
