[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] As shown in the accompanying drawings, an embodiment of the present invention provides an air guide mechanism, including: a shell 10, the shell 10 has an air duct and an air outlet connected to the air duct; a bottom plate 20, movably arranged on the shell 10, the bottom plate 20 has a closed position and an open position, wherein, when the bottom plate 20 is in the closed position, the periphery of the bottom plate 20 cooperates with the periphery of the air outlet, and when the bottom plate 20 is in the open position, the bottom plate 20 is located in the cavity of the shell 10; an air guide plate 30, swingably arranged on the bottom plate 20, the air guide plate 30 is used for guiding air, and when the bottom plate 20 is in the open position, the air guide plate 30 enters the cavity of the shell 10 with the bottom plate 20.

[0030] By applying the technical solution of the present invention, there is provided an air guide mechanism, which includes an outer shell 10, a base plate 20 and an air guide plate 30, wherein the outer shell 10 has an air duct and an air outlet connected to the air duct; the base plate 20 is movably arranged on the outer shell 10, and the base plate 20 has a closed position and an open position, wherein when the base plate 20 is in the closed position, the periphery of the base plate 20 cooperates with the periphery of the air outlet, and when the base plate 20 is in the open position, the base plate 20 is located in the cavity of the outer shell 10; the air guide plate 30 is swingably arranged on the base plate 20, and the air guide plate 30 is used for guiding air, and when the base plate 20 is in the open position, the air guide plate 30 enters the cavity of the outer shell 10 along with the base plate 20. With the above arrangement, when guiding the wind passing through the air outlet, the bottom plate 20 can be moved to the open position, and then the wind is guided by adjusting the angle of the wind guide plate 30. In this way, the bottom plate 20 and the wind guide plate 30 are both located in the cavity of the outer shell 10 and will not be exposed to the outside of the outer shell 10 when guiding the wind, thereby avoiding the wind guide plate 30 affecting the overall aesthetics.

[0031] In this embodiment, the air guide plate 30 has a retracted state and a wind guiding state, wherein when the air guide plate 30 is in the retracted state, the air guide plate 30 is attached to the bottom plate 20; when the air guide plate 30 is in the wind guiding state, an angle is formed between the air guide plate 30 and the bottom plate 20. Since the air guide plate 30 is attached to the bottom plate 20 when the air guide plate 30 is in the retracted state, the occupied space can be reduced and the appearance can be not affected. When the air guide plate 30 is in the wind guiding state, an angle is formed between the air guide plate 30 and the bottom plate 20, so that the air can be guided by the air guide plate 30.

[0032] In this embodiment, the air outlet has a closed state and an air outlet state, wherein when the air outlet is in the closed state, the bottom plate 20 is in the closed position and the air guide plate 30 is in the retracted state; when the air outlet is in the air outlet state, the bottom plate 20 is in the open position and the air guide plate 30 is in the retracted state. In this way, when the air outlet is in the closed state, the air outlet can be blocked by the bottom plate 20 and the air guide plate 30, and the above position setting makes the bottom plate 20 and the air guide plate 30 become part of the appearance structure of the air guide mechanism, and will not protrude from the housing 10, and the overall appearance is beautiful. When the air outlet is in the air outlet state, the bottom plate 20 is in the open position and the air guide plate 30 is in the retracted state, which can ensure the smoothness of the air duct and avoid blocking the air intake.

[0033] In this embodiment, the air outlet also has an air intake state. When the air outlet is in the air intake state, the bottom plate 20 is in the open position and the air guide plate 30 is in the air guide state; or, when the bottom plate 20 is in the closed position, the air guide plate 30 is in the air guide state. In this way, the air outlet can be used for both air intake and air discharge, enriching the function of the air guide mechanism. Moreover, when the air outlet is in the air intake state, through the cooperation of the bottom plate 20 and the air guide plate 30, there are two ways to achieve air intake, which is convenient for selection.

[0034] In this embodiment, when the air guide plate 30 is in the air guiding state, the air guide plate 30 has a first air guiding position and a second air guiding position with different angles relative to the bottom plate 20. In this way, the air guide plate 30 can be adjusted to move to the first air guiding position or the second air guiding position according to different needs, which has strong versatility and meets different needs.

[0035] In this embodiment, the outer surface of the bottom plate 20 is provided with a first avoidance groove. When the bottom plate 20 is in the closed position, the outer surface of the bottom plate 20 is flush with the outer surface of the housing 10. When the air guide plate 30 is in the retracted state, the air guide plate 30 is located in the first avoidance groove, and the surface of the air guide plate 30 on the side away from the first avoidance groove is flush with the outer surface of the bottom plate 20. When the bottom plate 20 is in the closed position, the outer surface of the bottom plate 20 is flush with the outer surface of the housing 10, which can make the outer surface of the air guide mechanism smooth and improve the aesthetics. When the air guide plate 30 is in the retracted state, the air guide plate 30 is located in the first avoidance groove, and the surface of the air guide plate 30 on the side away from the first avoidance groove is flush with the outer surface of the bottom plate 20, which can ensure that the inner wall of the area where the gas flows is smooth, reduce wind resistance, and facilitate gas flow.

[0036] In this embodiment, the bottom plate 20 has a first ventilation hole 21 for ventilation. When the wind guide plate 30 is in the retracted state, the wind guide plate 30 blocks the first ventilation hole 21; when the wind guide plate 30 is in the wind guiding state, the wind guide plate 30 avoids the first ventilation hole 21. In this way, when the air outlet does not emit air or the air outlet is used to emit air, the first ventilation hole 21 can be blocked by the wind guide plate 30 to avoid air leakage. Moreover, when the wind guide plate 30 is in the wind guiding state, the wind guide plate 30 avoids the first ventilation hole 21, so that the first ventilation hole 21 can be used for gas flow and facilitates gas passage.

[0037] Furthermore, a second ventilation hole is provided on the inner wall of the air duct, and when the bottom plate 20 is in the open position, the bottom plate 20 is attached to the inner wall of the air duct, and the second ventilation hole is connected to the first ventilation hole 21. Through the above arrangement, it is convenient for wind to pass through the bottom plate 20 and the inner wall of the air duct to achieve air intake.

[0038] In this embodiment, the air duct has a first inner wall 11 and a second inner wall 12 arranged at intervals. When the bottom plate 20 is in the open position, the bottom plate 20 is attached to the first inner wall 11; when the air guide plate 30 is in the air guiding state, there is a gap between the end of the air guide plate 30 away from the bottom plate 20 and the second inner wall 12. The bottom plate 20 is attached to the first inner wall 11, which can prevent the bottom plate 20 from obstructing the flow of gas. When the air guide plate 30 is in the air guiding state, there is a gap between the end of the air guide plate 30 away from the bottom plate 20 and the second inner wall 12, so that both sides of the air guide plate 30 can be used for air intake or air outlet.

[0039] In this embodiment, the first inner wall 11 has an air guiding surface and a second avoidance groove arranged on the air guiding surface. When the air outlet is in the air outlet state, at least a portion of the bottom plate 20 and at least a portion of the air guide plate 30 are both located in the second avoidance groove, and the surface of the bottom plate 20 facing the second inner wall 12 and the surface of the air guide plate 30 facing the second inner wall 12 are both flush with the air guiding surface. Through the above arrangement, when the air outlet is in the air outlet state, the position arrangement of the bottom plate 20 and the air guide plate 30 makes the inner wall of the area where the gas flows through smooth, which can reduce wind resistance and facilitate gas flow.

[0040] In this embodiment, there are two air outlets, which are respectively located at the upper end and the lower end of the air duct, two bottom plates 20, which are arranged one-to-one with the two air outlets, and two air guide plates 30, which are arranged one-to-one with the two bottom plates 20; wherein, the two air outlets are respectively the first air outlet and the second air outlet, and when the first air outlet is inlet, the second air outlet is outlet; when the first air outlet is outlet, the second air outlet is inlet. Through the above arrangement, the air guide mechanism can be switched to upper air intake and lower air outlet, or switched to lower air intake and upper air outlet, thereby enriching the functions of the air guide mechanism and the air conditioner using the air guide mechanism. For example, the air is discharged from the upper part during cooling and from the lower part during heating, which can improve the heat exchange effect and user comfort.

[0041] In this embodiment, the air guide mechanism further includes: a first driving unit 40, which is disposed on the housing 10, at least a portion of which is movably disposed, and the first driving unit 40 is drivingly connected to the bottom plate 20 to drive the bottom plate 20 to swing; a second driving unit 50, which is disposed on the bottom plate 20, at least a portion of which is movably disposed, and the second driving unit 50 is drivingly connected to the air guide plate 30 to drive the air guide plate 30 to swing. In this way, the positions of the bottom plate 20 and the air guide plate 30 can be automatically adjusted.

[0042] Specifically, the first driving unit 40 includes a gear 41 and an arc-shaped rack 42, the arc-shaped rack 42 is meshed with the gear 41, the gear 41 is rotatably arranged on the housing 10 to drive the arc-shaped rack 42 to rotate, one end of the arc-shaped rack 42 is connected to the bottom plate 20 to drive the bottom plate 20 to swing; the second driving unit 50 includes a stepping motor, the motor shaft of the stepping motor is drivingly connected to the air guide plate 30 to drive the air guide plate 30 to swing. With the above arrangement, the positions of the bottom plate 20 and the air guide plate 30 can be accurately controlled, and the transmission is reliable.

[0043] Optionally, the bottom plate 20 includes a baffle, a rotating shaft and a connecting piece, wherein the rotating shaft and the connecting piece are both arranged on the baffle, wherein the rotating shaft is hinged to the housing 10, the connecting piece is connected to the first driving part 40, and the baffle is used to block the air outlet. Furthermore, the connecting piece has a waist-shaped hole, and the connecting piece is movably connected to the arc-shaped rack 42 through the waist-shaped hole, so that the bottom plate 20 can be prevented from getting stuck when rotating.

[0044] Optionally, one end of the bottom plate 20 is rotatably disposed on an edge of the air outlet, and a limiting member is disposed on the other edge of the air outlet. The limiting member is located on the rotation path of the other end of the bottom plate, and when the bottom plate is rotated to the blocking position, the limiting member cooperates with the stopper at the other end of the bottom plate. In this way, the rotation position of the bottom plate 20 can be limited by the limiting member to prevent the bottom plate 20 from protruding from the housing 10.

[0045] Optionally, the first driving unit 40 further includes a motor and a transmission gear. The motor is arranged on the housing 10, the motor is drivingly connected to the gear, and the transmission gear is respectively meshed with the gear and the arc-shaped rack 42.

[0048] Another embodiment of the present invention provides an air conditioner, which includes the above-mentioned air guide mechanism. With the air conditioner, when guiding the wind passing through the air outlet, the bottom plate 20 can be moved to the open position, and then the wind is guided by adjusting the angle of the wind guide plate 30, so that the bottom plate 20 and the wind guide plate 30 are both located in the cavity of the housing 10, and will not be exposed to the outside of the housing 10 when guiding the wind, thereby avoiding the wind guide plate 30 affecting the overall aesthetics of the air conditioner. In addition, the air inlet and outlet methods of the air conditioner are flexible and diverse, which improves the user experience.
