[0031] The present utility model will be described in further detail below in conjunction with the drawings and specific embodiments, but not as a limitation to the present utility model.

[0032] Referring to Figures 1 to 9 , according to the embodiment of the present utility model, an air outlet assembly is provided, which comprises an air outlet frame 10 and an air deflector 20, the air outlet frame 10 is installed on a preset structure, the air outlet frame 10 forms an air outlet 11; the air deflector 20 is rotatably connected to the air outlet frame 10; the air deflector 20 is provided with a first matching structure A1 at the rotating shaft, the air outlet frame 10 is provided with a second matching structure A2 corresponding to the rotating shaft of the air deflector 20, and the first matching structure A1 and the second matching structure A2 form a labyrinth sealing structure in the position state of the air deflector 20 opening the air outlet 11.

[0033] When the air deflector in the air outlet assembly of the present utility model rotates and opens, the first matching structure and the second matching structure cooperate with each other to form a labyrinth sealing structure, which isolates the contact of cold and hot air inside and outside the air outlet at the rotating shaft of the air deflector and the assembly gap, prevents condensation from occurring at the rotating shaft of the air deflector, and effectively solves the problem of condensation when the air deflector is opened and closed at a large angle for long-distance air supply.

[0034] It should be noted that the first matching structure can be a structure space for the rotation of the second matching structure, and no specific matching is involved, and the second matching structure is the basic structure of the labyrinth seal structure. Alternatively, the second matching structure is a structure space for the rotation of the first matching structure, and no specific matching is involved, and the first matching structure is the basic structure of the labyrinth seal structure. Of course, the first matching structure and the second matching structure can also have part of the structure of the labyrinth seal structure, and the two structures only move to the position of forming the labyrinth seal structure when the position state of the air deflector opening the air outlet. The above structure can be selected according to the opening angle of the air deflector in the air outlet assembly.

[0035] In the embodiment, the first matching structure A1 is a tongue structure 21 on the air deflector 20, and the second matching structure A2 is a groove 12 on the air outlet frame 10.

[0036] In the position state of the air deflector 20 opening the air outlet 11, the tongue structure 21 is located in the groove 12, and the tongue structure 21 and the groove 12 cooperate to form a labyrinth seal structure. The gap between the tongue structure 21 and the side wall of the groove 12 forms a tortuous labyrinth, as shown in Figure 2 .

[0037] In the embodiment, the tongue structure 21 is used as the first matching structure A1, and the groove 12 is used as the second matching structure A2. Such structure is beneficial to sealing and forming a labyrinth seal structure. Moreover, the tongue structure 21 rotates with the air deflector 20, the travel trajectory of the tongue structure 21 is easy to plan, the structure of the groove is not easy to interfere with the tongue structure 21, the structure space is better utilized, and the air deflector is also easy to disassemble and overhaul.

[0038] Preferably, in combination with Figure 2 and Figure 4 As shown, the air deflector 20 is provided with a bending structure at the rotating shaft, and the bending structure includes a first bending segment 22, a second bending segment 23 and the tongue structure 21 connected in sequence.

[0039] The angle between the first bending segment 22 and the second bending segment 23 is less than 180°, and the angle between the second bending segment 23 and the tongue structure 21 is less than 180°.

[0040] In the position state of the air deflector 20 opening the air outlet 11, the bending structure blocks the gap between the air deflector 20 and the air outlet frame 10.

[0041] The bending structure also has a certain sealing effect. The bending structure and other structures of the air outlet frame can form a bending gap (same as the winding labyrinth gap principle), so that external air or internal cold air is difficult to flow to the tongue structure position of the air deflector, and it is more difficult to approach the assembly gap of the air deflector shaft, thereby increasing the sealing effect, preventing the air deflector and the air outlet frame from forming a cold and hot airflow intersection at the gap of the air deflector shaft, further reducing the risk of condensation, and effectively solving the condensation problem.

[0042] In the embodiment, the bending structure is Z-shaped or zigzag-shaped. The air outlet of the air outlet assembly can be used for long-distance cold air delivery, and the air deflector can be opened at a large angle. When the air deflector is rotated to a specified position, the gap between the air deflector and the air outlet frame is directly blocked by the zigzag-shaped bending structure, and the labyrinth sealing structure formed by the interlocking of the tongue structure and the groove in the zigzag-shaped bending structure can further block the cold air from passing through the gap.

[0043] Preferably, in combination with Figure 5 and Figure 6 As shown, the notch of the groove 12 is arranged outward, and in the position state where the air deflector 20 closes the air outlet 11, the tongue structure 21 is located at the notch position of the groove 12. The notch of the groove 12 is arranged outward, which means that the notch is directed to the external environment where the airflow blows, and it can also be understood that the notch is directed away from the inside of the air outlet frame.

[0044] The specific shape structure of the groove 12 and the cooperation of the tongue structure can make the structures of the two simpler and the structure volume smaller, so that the labyrinth sealing structure can avoid occupying too much structure space or too much volume, so that the volume of the air outlet assembly can be greatly reduced, and other structures can be easily installed. The air outlet frame can be easily installed on various adaptive structures or mounting structures.

[0045] Since the groove structure and the tongue structure can realize the labyrinth sealing structure through a simple structure, the labyrinth sealing structure can be integrally formed in structure, reducing the number of part mold opening and reducing production cost.

[0046] In order to further improve the air deflection effect of the air deflector, in the embodiment, a flow guide surface 24 is arranged on the windward surface of the air deflector 20, and the flow guide surface 24 is used to guide the airflow to flow upwards.

[0047] The design of the flow guide surface can make the cold air blowing more smoothly, the delivery distance farther, and the comfort of the cold air blowing improved.

[0048] In combination with Figure 3 and Figure 4As shown, the fitting plane where the flow guide surface 24 is located and the plane where the air deflector 20 is located have an inclination angle alpha, and the angle between the flow guide surface 24 and the air flow blowing direction of the air outlet 11 is smaller than the angle between the plane where the air deflector 20 is located and the air flow blowing direction of the air outlet 11.

[0049] The air flow blown by the air outlet is lifted upward after flowing through the flow guide surface, so that the cold air flow can pass over the free end of the air deflector, and the free end (the end of the air deflector in the air flow direction, Figure 3 the leftmost end) of the air deflector does not form condensation.

[0050] In the embodiment, the inclination angle alpha is between 7 degrees and 10 degrees. The inclination angle alpha is most preferably 8 degrees. The inclination angle alpha can balance the cold air blowing and the air speed, ensure the cold air delivery distance, and also make the cold air blow upward as much as possible, so as to achieve the comfort requirement that the air conditioner can make the cold air sink.

[0051] Preferably, the flow guide surface 24 extends to the free end 25 of the air deflector 20, and the connection between the flow guide surface 24 and the free end 25 of the air deflector 20 is a circular arc transition.

[0052] The connection between the flow guide surface 24 and the free end 25 of the air deflector 20 is a circular arc transition, and the circular arc transition or smooth transition structure can make the cold air blow smoothly and avoid the free end of the air deflector from forming condensation. The starting end of the flow guide surface is located at a position 183 mm away from the air deflector shaft, and the end of the flow guide surface is located at the free end 25.

[0053] In the embodiment, the recess 12 is provided with a flexible sealing layer. The flexible sealing layer such as a sponge plug in the recess 12 can further realize the sealing function.

[0054] Preferably, the top side wall of the recess 12 is formed by a flexible sealing layer, and a sealing fit is formed between the top side wall of the recess 12 and the bending structure in the position state where the air deflector 20 opens the air outlet 11. The above structure fit can further seal on the labyrinth sealing structure, prevent condensation, and improve the condensation prevention effect.
