Description

Technical Field

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

[0002] At present, the air outlets of traditional duct air conditioners are mostly engineering air outlets and louver air outlets. The cooling air supply distance of these air outlets is relatively short, and it is difficult to achieve long-distance waterfall air supply;

[0003] In order to achieve long-distance waterfall-style air supply, if the fan speed is increased, the noise will increase accordingly; if the entire air guide plate is opened and closed at a large angle, due to the problem of installing the rotating shaft of the air guide plate, there will be a certain gap between the air guide plate and the air outlet frame. The gap will cause the cold and hot air flows to converge here and produce condensation.

[0004] In summary, the matching structure of the air guide plate in the prior art is prone to condensation. Summary of the invention

[0005] An embodiment of the present invention provides an air outlet assembly and an air conditioner to solve the problem that condensation is easily generated in the matching structure of the air guide plate in the prior art.

[0006] To achieve the above-mentioned objectives, the present invention provides an air outlet assembly, comprising: an air outlet frame, which is installed on a preset structure, and the air outlet frame forms an air outlet; an air guide plate, which is rotatably connected to the air outlet frame; the air guide plate is provided with a first matching structure at the rotating shaft, and the air outlet frame is provided with a second matching structure at the rotating shaft corresponding to the air guide plate, and when the air guide plate is in a position to open the air outlet, the first matching structure and the second matching structure cooperate with each other to form a labyrinth sealing structure.

[0007] Further, the first matching structure is a tongue structure on the air guide plate, and the second matching structure is a groove on the air outlet frame;

[0008] When the air guide plate opens the air outlet, the tongue structure is located in the groove, and the tongue structure cooperates with the groove to form a labyrinth sealing structure, and a tortuous labyrinth gap is formed between the tongue structure and the side wall of the groove.

[0009] Furthermore, the wind deflector is provided with a bending structure at the rotating shaft, and the bending structure comprises a first bending section, a second bending section and the tongue structure which are connected in sequence;

[0010] The angle between the first bending section and the second bending section is less than 180°, and the angle between the second bending section and the tongue structure is less than 180°;

[0011] When the air guide plate opens the air outlet, the bending structure blocks the gap between the air guide plate and the air outlet frame.

[0012] Furthermore, the bending structure is in a Z shape or a zigzag shape.

[0013] Furthermore, the notch of the groove is arranged toward the outside, and when the air guide plate is in a position to close the air outlet, the tongue structure is located at the notch of the groove.

[0014] Furthermore, a guide surface is provided on the windward surface of the wind guide plate, and the guide surface is used to guide the airflow to flow upward.

[0015] Furthermore, there is an inclination angle between the fitting plane where the guide surface is located and the plane where the air guide plate is located, and the angle between the guide surface and the blowing direction of the airflow from the air outlet is smaller than the angle between the plane where the air guide plate is located and the blowing direction of the airflow from the air outlet.

[0016] Furthermore, the inclination angle is between 7° and 10°.

[0017] Furthermore, the guide surface extends to the free end of the wind guide plate, and the connection between the guide surface and the free end of the wind guide plate is an arc transition.

[0018] Furthermore, a flexible sealing layer is arranged in the groove.

The labyrinth sealing structure isolates the contact between the cold and hot air inside and outside the air outlet at the air guide plate shaft and the assembly gap, preventing condensation from being generated at the air guide plate shaft, and effectively solving the problem of condensation generated when the air guide plate is opened and closed at a large angle for long-distance air delivery.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0032] See also Figures 1 to 9 As shown, according to an embodiment of the present invention, an air outlet component is provided, which includes an air outlet frame 10 and an air guide plate 20, wherein the air outlet frame 10 is installed on a preset structure, and the air outlet frame 10 forms an air outlet 11; the air guide plate 20 is rotatably connected to the air outlet frame 10; the air guide plate 20 is provided with a first matching structure A1 at the rotating shaft, and the air outlet frame 10 is provided with a second matching structure A2 at the rotating shaft corresponding to the air guide plate 20, and when the air guide plate 20 is in a position to open the air outlet 11, the first matching structure A1 and the second matching structure A2 match each other to form a labyrinth sealing structure.

[0033] When the air guide plate in the air outlet assembly of the present invention is rotated open, the first matching structure and the second matching structure cooperate with each other to form a labyrinth sealing structure. The labyrinth sealing structure isolates the contact between the cold and hot air inside and outside the air outlet at the air guide plate shaft and the assembly gap, preventing condensation from being generated at the air guide plate shaft, and effectively solving the problem of condensation generated when the air guide plate is opened and closed at a large angle for long-distance air delivery.

[0034] It should be noted that the first matching structure can be a structural space for the second matching structure to rotate, which does not involve specific matching, and the second matching structure is the entire basic structure of the labyrinth sealing structure. Alternatively, the second matching structure is a structural space for the first matching structure to rotate, which does not involve specific matching, and the first matching structure is the entire basic structure of the labyrinth sealing structure. Of course, it is also possible that the first matching structure and the second matching structure each have a partial structure of the labyrinth sealing structure, and when the air guide plate opens the air outlet, the two structures move to the position to form the labyrinth sealing structure. The above-mentioned structural form can be selected according to the opening and closing angle of the air guide plate in the air outlet assembly.

[0035] In this embodiment, the first matching structure A1 is the tongue structure 21 on the air guide plate 20, and the second matching structure A2 is the groove 12 on the air outlet frame 10;

[0036] When the air guide plate 20 opens the air outlet 11, the tongue structure 21 is located in the groove 12, and the tongue structure 21 cooperates with the groove 12 to form a labyrinth sealing structure, and a tortuous labyrinth gap is formed between the tongue structure 21 and the side wall of the groove 12, see Figure 2 .

[0037] In this 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 a structure is conducive to sealing and forming a labyrinth sealing structure. In addition, the tongue structure 21 rotates with the air guide plate 20. The movement 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 structural space is better utilized, and the air guide plate is easy to disassemble and repair.

[0038] Preferably, combined Figure 2 and Figure 4 As shown, the wind deflector 20 is provided with a bending structure at the rotating shaft, and the bending structure includes a first bending section 22, a second bending section 23 and the tongue structure 21 which are connected in sequence;

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

[0040] When the air guide plate 20 opens the air outlet 11 , the bending structure blocks the gap between the air guide plate 20 and the air outlet frame 10 .

[0041] The above-mentioned bending structure also plays a certain sealing role. A bending gap can also be formed between the bending structure and other structures of the air outlet frame (with the same principle as the zigzag maze gap), making it difficult for external air or internal cold air to flow to the tongue structure position of the air guide plate, and even more difficult to approach the assembly gap at the air guide plate shaft, thereby increasing the sealing effect and preventing the air guide plate and the air outlet frame from forming a confluence of cold and hot air flows at the gap at the air guide plate shaft, further reducing the risk of condensation and effectively solving the condensation problem.

[0042] In this embodiment, the bending structure is Z-shaped or zigzag-shaped. The air outlet of the air outlet assembly can be used to deliver cold air over a long distance, and the air guide plate can be opened at a larger angle. When the air guide plate rotates to a specified position, the gap between the air guide plate and the air outlet frame is directly blocked by the zigzag bending structure on the one hand, and the labyrinth sealing structure formed by the engagement of the tongue structure and the groove in the zigzag bending structure can further block the cold air from passing through the gap.

[0043] Preferably, combined Figure 5 and Figure 6 As shown, the notch of the groove 12 is arranged toward the outside, and when the air guide plate 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 toward the outside, which means that the notch faces the external environment blown by the airflow, and can also be understood as the direction of the notch away from the inside of the air outlet frame.

[0044] The coordination of the specific shape structure of the groove 12 and the tongue structure can make the structures of the two simpler and reduce the structural volume, and can avoid the labyrinth sealing structure occupying too much structural space or too much volume, so that the volume of the air outlet component can be greatly reduced, which facilitates the installation of other structures and the installation of the air outlet frame on various adapter 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 formed by structural integration, thereby reducing the number of parts molds and reducing production costs.

[0046] In order to further improve the wind guiding effect of the wind guide plate, in the present embodiment, a guide surface 24 is provided on the windward surface of the wind guide plate 20, and the guide surface 24 is used to guide the airflow to flow upward.

[0047] The design of the guide surface can make the cold air blow more smoothly and transport it over a longer distance, thereby improving the comfort of the cold air.

[0048] Combination Figure 3 and Figure 4As shown, there is an inclination angle α between the fitting plane where the guide surface 24 is located and the plane where the air guide plate 20 is located, and the angle between the guide surface 24 and the airflow blowing direction of the air outlet 11 is smaller than the angle between the plane where the air guide plate 20 is located and the airflow blowing direction of the air outlet 11.

[0049] The airflow from the air outlet rises upward after passing through the guide surface, so that the cold air flow can pass over the free end of the air guide plate, avoiding the free end of the air guide plate (the end of the air guide plate in the airflow direction, Figure 3 Condensation forms on the far left side of the

[0050] In this embodiment, the angle of the inclination angle α is between 7° and 10°. The most preferred inclination angle α is 8°, which can balance the horizontal blowing of cold air and the wind speed, ensure the cold air delivery distance, and at the same time, the cold air can be blown upward as much as possible, so as to meet the comfort requirement that the air conditioner can sink the cold air.

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

[0052] The connection between the guide surface 24 and the free end 25 of the air guide plate 20 is an arc transition. The arc transition or smooth transition structure can make the cold air blow out smoothly and avoid condensation at the free end of the air guide plate. The starting end of the guide surface is 183mm away from the air guide plate shaft, and the end of the guide surface is at the free end 25.

[0053] In this embodiment, a flexible sealing layer is provided in the groove 12. A flexible sealing layer such as a sponge is plugged into the groove 12 to further achieve a sealing function.

[0054] Preferably, the top side wall of the groove 12 is formed by a flexible sealing layer, and when the air guide plate 20 opens the air outlet 11, a sealing fit is formed between the top side wall of the groove 12 and the bent structure. The above structural fit can further seal the labyrinth sealing structure to prevent condensation and improve the anti-condensation effect.
