Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air duct device and an air conditioner. Background Art

[0002] 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. Summary of the Invention

[0003] The problem solved by the present invention is how to reduce the loss of air outlet of an air conditioner when the air outlet angle of the air conditioner is adjustable.

[0004] To solve the above problems, embodiments of the present invention provide an air duct device and an air conditioner, which can improve the air volume loss of the air outlet of the indoor unit.

[0011] The present invention utilizes a movable air guide within the air outlet duct. The air guide can selectively cooperate with either the upper or lower sidewall of the air outlet duct according to the operating state of the air conditioner, thereby changing the structure of the air duct to achieve upward or downward air guidance, thereby avoiding loss of air volume. Furthermore, the air guide can also close the air outlet duct when the air conditioner is turned off, thereby reducing the risk of dust entering the air conditioner when the air conditioner is turned off.

[0025] When the air conditioner is in the off state, the air guide member can be rotated so that one side of the first guide surface abuts against the upper side wall of the air outlet duct, and the other side abuts against the lower side wall of the air outlet duct; or, when the air conditioner is in the off state, the air guide member can be rotated so that one side of the second guide surface abuts against the upper side wall of the air outlet duct, and the other side abuts against the lower side wall of the air outlet duct.

[0026] When the air conditioner is turned off, the present application improves the sealing between the air guide member and the air duct body by allowing the opposite sides of the air guide member to abut against the lower side wall and the upper side wall of the air outlet duct respectively.

DETAILED DESCRIPTION

[0042] When an air conditioner blows air directly toward the user through the air outlet, the airflow velocity is high, and the hot and cold air blows directly toward the user, which can easily cause discomfort. Existing air conditioners typically adjust the angle of the air deflector to block the airflow and prevent it from blowing directly toward the user. However, this approach results in a loss of air output from the air conditioner 300.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] Please refer to Figures 1-4In 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.

[0045] 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 an indoor unit body and an air duct device 100 disposed on the indoor unit body. The air duct device 100 is used to discharge air from the indoor unit 310 to adjust the indoor environment.

[0046] 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.

[0047] 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.

[0048] In this embodiment, the air duct device 100 includes an air duct body 110 and an air guide 130. The air duct body 110 has an air outlet duct 111. The air guide 130 is movably arranged in the air outlet duct 111. When the air conditioner 300 is in the first state, the air guide 130 can be moved to cooperate with the upper side wall of the air outlet duct 111 to guide the air. When the air conditioner 300 is in the second state, the air guide 130 can be moved to cooperate with the lower side wall of the air outlet duct 111 to guide the air. When the air conditioner 300 is in the off state, the air guide 130 can be moved to close the air outlet duct 111.

[0049] This embodiment utilizes a movable air guide 130 within the outlet duct 111. Depending on the operating state of the air conditioner 300, the air guide 130 can selectively engage with either the upper or lower sidewall of the outlet duct 111, thereby changing the structure of the duct to achieve upward or downward air guidance, thereby preventing loss of airflow. Furthermore, the air guide 130 can also close the outlet duct 111 when the air conditioner 300 is turned off, thereby preventing dust from entering the air conditioner 300 when the air conditioner is turned off.

[0050] Please refer to Figure 2 and Figure 3In this embodiment, the upper side wall of the air outlet duct 111 is provided with a first mating surface 113, and the lower side wall of the air outlet duct 111 is provided with a second mating surface 115. The first state is the heating state. When the air conditioner 300 is in the heating state, the air guide 130 can move to fit with the second mating surface 115, and in the heating state, the air guide 130 can guide air downward. The second state is the cooling state. When the air conditioner 300 is in the cooling state, the air guide 130 can move to fit with the first mating surface 113, and in the cooling state, the air guide 130 can guide air upward.

[0051] In this embodiment, the heating effect of the air conditioner 300 can be improved by allowing the air guide 130 to fit with the second mating surface 115 in the heating mode, and allowing the air guide 130 to use the Coanda effect to guide the hot air flow downward. In the cooling mode, the air guide 130 can be fitted with the first mating surface 113, and allowing the air guide 130 to use the Coanda effect to guide the cold air upward, thereby improving the cooling effect of the air conditioner 300.

[0052] Of course, in other embodiments of the present application, by changing the structure of the air duct body 110 and the structure of the air guide 130, the air guide 130 can cooperate with the lower side wall of the air outlet duct 111 and guide the air upward when the air conditioner 300 is in the heating state. When the air conditioner 300 is in the cooling state, the air guide 130 can cooperate with the upper side wall of the air outlet duct 111 to guide the air downward. It can be understood that in this embodiment, the structure of the air outlet duct 111 is changed by the air guide 130 to achieve downward and upward air guidance.

[0053] In this embodiment, the air guide 130 includes a first guide surface 131 and a second guide surface 133 disposed opposite each other. When the air conditioner 300 is in heating mode, the first guide surface 131 abuts against the second mating surface 115, and the second guide surface 133 directs air downward. When the air conditioner 300 is in cooling mode, the first guide surface 131 abuts against the first mating surface 113, and the second guide surface 133 directs air upward.

[0054] The present application provides a first guide surface 131 that fits with the first mating surface 113 or the second mating surface 115 according to different states of the air conditioner 300 , thereby improving the air flow of the air outlet duct 111 to make it smoother.

[0055] In other embodiments of the present application, when the air conditioner 300 is in heating mode, the first guide surface 131 is in contact with the second mating surface 115, and the second guide surface 133 can direct air downward. When the air conditioner 300 is in cooling mode, the second guide surface 133 is in contact with the first mating surface 113, and the first guide surface 131 is used to direct air upward. By arranging the first guide surface 131 to align with the second mating surface 115 in heating mode and arranging the second guide surface 133 to align with the first mating surface 113 in cooling mode, air flow from the air outlet duct 111 can be made smoother.

[0056] Please refer to Figure 4 In this embodiment, the air guide member 130 is rotatably provided on the air duct body 110. When the air conditioner 300 is in the off state, the air guide member 130 can be rotated so that one side of the first guide surface 131 abuts against the upper side wall of the air outlet duct 111, and the other side abuts against the lower side wall of the air outlet duct 111.

[0057] When the air conditioner 300 of this embodiment is turned off, the sealing between the air guide 130 and the duct body 110 can be improved by allowing the opposite sides of the air guide 130 to abut against the lower side wall of the air outlet duct 111 and the upper side wall of the air outlet duct 111 respectively.

[0058] Of course, in some other embodiments of the present application, or when the air conditioner 300 is in the off state, the air guide member 130 can be rotated to make one side of the second guide surface 133 abut against the upper side wall of the air outlet duct 111, and the other side abut against the lower side wall of the air outlet duct 111.

[0059] In this embodiment, the air duct device 100 also includes a driving component (not shown in the figure), which is arranged on the air duct body 110. A rotating link 117 is provided on the air guide member 130. The air guide member 130 is rotatably arranged on the air duct body 110 through the rotating link 117, and the driving component is transmission-connected to the rotating link 117. The driving component can drive the rotating link 117 to rotate to drive the air guide member 130 to rotate.

[0060] In this embodiment, a driving assembly and a rotating connecting rod 117 are provided to drive the rotating connecting rod 117 to rotate and drive the air guide member 130 to cooperate with the upper side wall and the lower side wall of the air channel to realize upward air guidance, downward air guidance and closing of the air outlet duct 111.

[0061] It should be noted that the shape of the rotating link 117 can be set according to the three positions of the first fitting surface, the second fitting surface and the air guide 130 closing the air outlet duct 111. This embodiment does not limit the rotating link 117 to a straight rod shape.

[0062] In some embodiments of the present application, the rotating link 117 may be curved or formed by bending.

[0063] Please refer to Figure 5 In this embodiment, the air guide member 130 has a shuttle-shaped structure, and the opposite sides of the first guide surface 131 are respectively connected to the opposite sides of the second guide surface 133. The first guide surface 131 is a convex arc surface, and the first guide surface 131 is convex in the direction away from the second guide surface 133.

[0064] In this embodiment, the first guide surface 131 is configured as a convex arc surface so that the first guide surface 131 can guide the wind by utilizing the Coanda effect, thereby better guiding the wind without blocking the air output.

[0065] In this embodiment, the second guide surface 133 is a convex arc surface, and the second guide surface 133 is convex in a direction away from the first guide surface 131 .

[0066] In this embodiment, the second guide surface 133 is configured as a convex arc surface so that the second guide surface 133 can guide the wind by utilizing the Coanda effect, thereby better guiding the wind without blocking the air output.

[0067] In this embodiment, the air guide 130 is disposed on a side of the air outlet duct 111 close to the air outlet.

[0068] In this embodiment, the air guide member 130 is arranged on a side of the air outlet duct 111 close to the air outlet, so that the air guide member 130 can have a better air guiding effect.

[0069] In summary, the working principles and beneficial effects of the air guide device and air conditioner 300 provided by the embodiments of the present invention include:

[0070] This embodiment utilizes a movable air guide 130 within the outlet duct 111 of the air duct device 100 of the air conditioner 300. The air guide 130 can selectively engage with either the upper or lower sidewall of the outlet duct 111, depending on the operating state of the air conditioner 300, thereby changing the structure of the duct to achieve upward or downward air guidance, thereby preventing loss of airflow. Furthermore, the air guide 130 can also close the outlet duct 111 when the air conditioner 300 is turned off, thereby preventing dust from entering the air conditioner 300 when the air conditioner is turned off.

[0071] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
