DETAILED DESCRIPTION

[0044] When an air conditioner blows air directly toward the user through the outlet, the airflow is high in velocity, causing hot and cold air to blow directly at the user, which can easily cause discomfort. Existing air conditioners typically block the airflow by adjusting the angle of the air deflector to prevent it from directly hitting the user. However, this approach results in a loss of airflow.

[0045] Please refer to Figures 1-4 In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] An embodiment of the present invention provides an air conditioner 300, which includes an indoor unit 310 and an outdoor unit. The outdoor unit and the indoor unit 310 are connected by a pipe to adjust the indoor environment. The indoor unit 310 includes a main body of the indoor unit 310 and an air duct device 100 disposed on the main body of the indoor unit 310. The air duct device 100 is used to discharge air from the indoor unit 310 to adjust the indoor environment.

[0047] In this embodiment, the indoor unit 310 is an indoor hanging unit. In other embodiments of the present application, the indoor unit 310 may also be of other types.

[0048] In this embodiment, the indoor unit 310 includes a middle frame 311 and a heat exchanger and a fan 313 disposed in the middle frame 311. The air duct device 100 is installed on one side of the air outlet of the fan 313, and the heat exchanger is installed on one side of the air inlet of the fan 313.

[0049] In the present embodiment, the air duct device 100 includes an air duct body 110, an air guide 130 and a drive assembly 150. The air duct body 110 has an air outlet channel 111, and the air guide 130 is movably arranged in the air outlet channel 111. The drive assembly 150 is transmission-connected to the air guide 130, and the drive assembly 150 is used to drive the air guide 130 to move. When the air conditioner 300 is in the first state, the drive assembly 150 can drive the air guide 130 to move to cooperate with the lower side wall of the air outlet channel 111 so that the air guide 130 guides the air downward. When the air conditioner 300 is in the second state, the drive assembly 150 can drive the air guide 130 to move to cooperate with the upper side wall of the air outlet channel 111 so that the air guide 130 guides the air upward.

[0050] In this embodiment, the air guide member 130 is movably arranged in the air outlet channel 111. According to different working states of the air conditioner 300, the driving component 150 is used to move the air guide member 130 to selectively cooperate with the lower side wall of the air outlet channel 111 or the upper side wall of the air outlet channel 111, so that the shape of the air outlet channel 111 is changed by the movement of the air guide member 130 so that the air guide member 130 can guide the air downward or upward, thereby improving the loss of air outlet volume when the air conditioner 300 adjusts the air outlet angle.

[0051] Please continue to refer to Figures 1-4 In this embodiment, the air guide 130 is movably disposed in the air outlet channel 111, and the driving component 150 can drive the air guide 130 to move so that the air guide 130 cooperates with the lower side wall of the air outlet channel 111 or the upper side wall of the air outlet channel 111.

[0052] In this embodiment, the air guide 130 is movably arranged in the air outlet channel 111, so that the driving component 150 can be conveniently used to achieve selective cooperation between the air guide 130 and the upper side wall and the lower side wall of the air outlet channel 111, which has a simple structure and is more convenient to control.

[0053] In this embodiment, the air guide member 130 has a first air guide surface 131 and a second air guide surface 133. The air guide member 130 is movably and rotatably arranged on the air duct body 110. The first state is the heating state, and the second state is the cooling state. When the air conditioner 300 is in the heating state, the driving component 150 can drive the air guide member 130 to move and rotate so that the first air guide surface 131 cooperates with the upper side wall of the air outlet channel 111, and the second air guide surface 133 can guide the air downward. When the air conditioner 300 is in the cooling state, the driving component 150 can drive the air guide member 130 to move and rotate so that the second air guide surface 133 fits with the lower side wall of the air outlet channel 111, and the first air guide surface 131 can guide the air upward.

[0054] In the present application, when the air conditioner 300 is in the heating state, the driving assembly 150 drives the air guide member 130 so that the first air guide surface 131 cooperates with the upper side wall of the air outlet channel 111, thereby causing the second air guide surface 133 to guide air downward, thereby alleviating the rise of hot air and improving the heating effect of the air conditioner 300. When the air conditioner 300 is in the cooling state, the driving assembly 150 drives the air guide member 130 so that the second air guide surface 133 cooperates with the upper side wall of the air outlet channel 111, thereby causing the first air guide surface 131 to guide air downward, thereby alleviating the downward flow of cold air and improving the cooling effect of the air conditioner 300.

[0055] Of course, in some other embodiments of the present application, the second state may also be a working mode such as defrosting.

[0056] Of course, in other embodiments of the present application, when the air conditioner 300 is in a heating state, the driving assembly 150 can drive the air guide member 130 to move and rotate so that the first air guide surface 131 cooperates with the upper side wall of the air outlet channel 111 and the second air guide surface 133 guides the air downward; when the air conditioner 300 is in a cooling state, the driving assembly 150 can drive the air guide member 130 to move and rotate so that the first air guide surface 131 fits with the lower side wall of the air outlet channel 111 and the second air guide surface 133 guides the air upward. It is understood that as long as one of the first air guide surface 131 and the second air guide surface 133 of the air guide member 130 fits with the upper side wall or the lower side wall of the air outlet channel 111, the other one can be used to guide the air upward or downward.

[0057] In this embodiment, when the air conditioner 300 is in the heating state, the driving assembly 150 drives the air guide member 130 so that the first air guide surface 131 cooperates with the upper side wall of the air outlet passage 111, thereby causing the second air guide surface 133 to guide air downward, thereby alleviating the upward movement of hot air and improving the heating effect of the air conditioner 300. When the air conditioner 300 is in the cooling state, the driving assembly 150 drives the air guide member 130 so that the first air guide surface 131 cooperates with the upper side wall of the air outlet passage 111, thereby causing the second air guide surface 133 to guide air downward, thereby alleviating the downward movement of cold air and improving the cooling effect of the air conditioner 300.

[0058] Please continue to refer to Figures 1-4 In this embodiment, the air guide member 130 has a shuttle-shaped structure, and the first air guide surface 131 and the second air guide surface 133 are both convex arc-shaped. The first air guide surface 131 is convex in the direction away from the second air guide surface 133, and the second air guide surface 133 is convex in the direction away from the first air guide surface 131, and the opposite sides of the first air guide surface 131 are respectively connected to the opposite sides of the second air guide surface 133, and the first air guide surface 131 and the second air guide surface 133 have the same shape.

[0059] Of course, in some other embodiments of the present application, the shapes of the first wind guiding surface 131 and the second wind guiding surface 133 may also be different, for example, the curvatures may be different.

[0060] In this embodiment, the air duct device 100 also includes a transmission member 170, which is arranged on the air guide member 130, and the transmission member 170 is movably and rotatably arranged on the air duct body 110. The driving component 150 is transmission-connected to the transmission member 170, and the driving component 150 can drive the transmission member 170 to rotate while moving.

[0061] In this embodiment, a transmission member 170 is provided on the air guide member 130 , so that the transmission member 170 can be better connected to the driving assembly 150 , so that the driving assembly 150 can simultaneously drive the air guide member 130 to move and rotate.

[0062] Of course, in some other embodiments of the present application, the transmission member 170 may also be installed in the air duct body 110 by only rotating or only moving.

[0063] Please continue to refer to Figures 1-4 In this embodiment, the air duct body 110 includes an upper air duct plate 113, a lower air duct plate 115 and an end plate 117. The end plate 117 is arranged between the upper air duct plate 113 and the lower air duct plate 115, and the end plate 117 is connected to the lower air duct plate 115 and the upper air duct plate 113. The upper air duct plate 113, the end plate 117 and the lower air duct plate 115 enclose an air outlet channel 111. A guide groove 119 is provided on the end plate 117. The air guide member 130 is movably and rotatably installed in the guide groove 119. The driving component 150 can drive the air guide member 130 to move along the guide groove 119 while rotating.

[0064] In the present application, a guide groove 119 is provided on the end plate 117 so that the driving assembly 150 drives the air guide member 130 to move along the guide groove 119, thereby making the movement of the air guide member 130 controllable and the transmission more stable.

[0065] In this embodiment, a first bonding surface 121 is provided on the upper air duct plate 113, and a second bonding surface 123 is provided on the lower air duct plate 115. When the air conditioner 300 is in cooling mode, one of the first air guide surface 131 and the second air guide surface 133 is in contact with the first bonding surface 121, while the other guide surface guides air upwards using the Coanda effect. However, when the air conditioner 300 is in heating mode, one of the first air guide surface 131 and the second air guide surface 133 is in contact with the second bonding surface 123, while the other guide surface guides air downwards using the Coanda effect.

[0066] In this embodiment, the first fitting surface 121 and the second fitting surface 123 are in a groove shape, so as to better guide the wind with the first wind guiding surface 131 and the second wind guiding surface 133 .

[0067] In this embodiment, the transmission member 170 is movably and rotatably arranged in the guide groove 119, and the transmission member 170 is transmission-connected to the driving assembly 150. The driving assembly 150 can drive the transmission member 170 to move and rotate along the guide groove 119 to drive the air guide member 130 to move and rotate at the same time.

[0068] The present application provides a transmission member 170 on the air guide member 130 and a guide groove 119 on the end plate 117 , and installs the transmission member 170 movably and rotatably in the guide groove 119 , thereby better realizing the movement of the air guide member 130 .

[0069] Of course, in some other embodiments of the present application, the movement and rotation of the air guide member 130 may not be performed simultaneously. For example, the air guide member 130 is first moved a preset distance and then rotated and then moved again.

[0070] In this embodiment, the transmission member 170 is an arc-shaped bar 171, the guide groove 119 is an arc-shaped groove 125, and the arc-shaped bar 171 is movably arranged in the arc-shaped groove 125. The arc-shaped bar 171 is transmission-connected to the driving component 150, and the driving component 150 can drive the arc-shaped bar 171 to slide along the side wall of the arc-shaped groove 125.

[0071] In the present application, the guide groove 119 is set as an arc groove 125 and the transmission member 170 is set as an arc bar 171, so that the arc bar 171 can rotate when it moves along the arc groove 125, making the transmission structure simpler.

The gear 151 is in driving connection with the drive member and meshes with the meshing teeth 173. When the drive member is operated, the gear 151 drives the arcuate strip 171 to move along the arcuate groove 125.

[0073] The present application provides meshing teeth 173 on the arc strip 171 and configures the driving assembly 150 as a driving member and a gear 151, and utilizes the driving member to drive the gear 151 to rotate, thereby driving the arc strip 171 to rotate while moving, so that it can be conveniently integrated into the indoor unit 310.

[0074] Of course, in some other embodiments of the present application, the meshing teeth 173 may also be provided on the outer circumference of the arc strip 171 , and the inner circumference of the arc strip 171 abuts against the arc groove 125 .

[0075] In this embodiment, the driving member is a motor, and the gear 151 is mounted on the output shaft of the motor. The motor is mounted on the air duct body 110. Of course, in other embodiments of the present application, the motor can also be mounted on the middle frame 311 of the air conditioner 300, and the arcuate groove 125 can also be formed on the middle frame 311 of the air conditioner 300.

[0076] In summary, the working principles and beneficial effects of the air duct device 100 and the air conditioner 300 provided in this embodiment include:
