[0065] In existing ventilation equipment, in order to improve the air outlet effect, a wind sweeping mechanism or a wind guiding mechanism is provided at the air outlet. The wind sweeping mechanism or the wind guiding mechanism includes a plurality of wind guiding plates. By controlling the rotation of the wind guiding plates, the air is guided above, below, to the left or to the right of the air outlet.

[0068] Embodiment 1

[0069] <Air outlet device>

[0070] As Figures 1a to 6 shown, this embodiment provides an air outlet device, including:

[0071] An air outlet frame 1, one end of which forms an air inlet 16 of the air outlet frame, and the other end of the air outlet frame 1 forms an air outlet 17 of the air outlet frame. An air outlet duct 18 communicating the air inlet 16 of the air outlet frame and the air outlet 17 of the air outlet frame is formed inside the air outlet frame 1. The air outlet duct 18 includes a first air outlet duct wall 11 and a second air outlet duct wall 12 arranged opposite to each other, and a third air outlet duct wall 13 and a fourth air outlet duct wall 14 arranged opposite to each other. The first air outlet duct wall 11, the third air outlet duct wall 13, the second air outlet duct wall 12 and the fourth air outlet duct wall 14 are sequentially connected and enclose the air outlet duct 18. One of the first air outlet duct wall 11 and the second air outlet duct wall 12 forms an air guiding surface 115 of the air outlet duct;

[0072] The air deflector 2, one end of which is rotatably arranged on the other one of the first air outlet duct wall 11 and the second air outlet duct wall 12; the air deflector 2 is arranged close to the air outlet 17 of the air outlet frame, and the air deflector 2 is formed with an air deflector surface 21; there is only one air deflector 2, and the air deflector 2 can be controlled to open or close the air outlet 17 of the air outlet frame or adjust the air outlet direction of the air outlet 17 of the air outlet frame;

[0073] When the air outlet 17 of the air outlet frame is in an open state and the air deflector surface 21 of the air deflector and the air duct deflector surface 115 are arranged oppositely, the air deflector surface 21 of the air deflector and the air duct deflector surface 115 cooperate to guide the air in the air outlet duct 18; by adjusting the position of the air deflector surface 21 of the air deflector relative to the air duct deflector surface 115, the air outlet direction of the air in the air outlet duct 18 can be adjusted;

[0074] Specifically, the size of the air deflector 2 is designed according to the size of the air outlet 17 of the air outlet frame, and the area of the air deflector 2 is greater than or equal to the flow area of the air outlet 17 of the air outlet frame, preventing air leakage at the edge of the air outlet 17 of the air outlet frame when the air deflector 2 closes the air outlet 17 of the air outlet frame, and at the same time the air deflector 2 can beautify the appearance; preferably, the air deflector 2 rotates up and down to adjust the air outlet direction of the air outlet 17 of the air outlet frame;

[0075] By replacing multiple small air deflectors with one large air deflector, the number of air deflectors is reduced, the structure and the assembly process are simplified, the assembly efficiency is improved, and thus the production efficiency of the whole machine is improved, solving the problem in the prior art that the air guiding mechanism requires many small air deflectors, resulting in a complex structure and a cumbersome assembly process; by controlling the rotation of one large air deflector, a large range of air guiding can be realized, and the air guiding effect is obvious.

[0076] The first air outlet duct wall 11 and the second air outlet duct wall 12 can be arranged oppositely up and down or left and right; when the first air outlet duct wall 11 and the second air outlet duct wall 12 are arranged oppositely up and down, the air deflector surface 21 of the air deflector and the air duct deflector surface 115 cooperate to guide the air from the air outlet 17 of the air outlet frame to the front upper or front lower or directly front; when the first air outlet duct wall 11 and the second air outlet duct wall 12 are arranged oppositely left and right, the air deflector surface 21 of the air deflector and the air duct deflector surface 115 cooperate to guide the air from the air outlet 17 of the air outlet frame to the front left or front right or directly front;

[0079] When the air deflector 2 is in the second air guiding position, a second air guiding area 24 is formed between the air guiding surface 21 of the air deflector and the air guiding surface of the air outlet duct, and the air in the second air guiding area 24 can be discharged directly in front of the air outlet 17 of the air outlet frame.

[0080] Furthermore, the first air outlet duct wall 11 is located above the second air outlet duct wall 12;

[0081] The end of the air deflector 2 close to the air outlet 17 of the air outlet frame is rotatably arranged on the side surface of the first air outlet duct wall 11 facing the second air outlet duct wall 12. The air deflector 2 can be controlled to rotate up and down, and thus the air deflector 2 can be in the first air guiding position and the second air guiding position. When the air outlet 17 of the air outlet frame is in the open state, a air guiding surface 21 of the air deflector is formed on the side of the air deflector 2 facing the air guiding surface 115 of the air outlet duct;

[0082] The side surface of the second air outlet duct wall 12 facing the first air outlet duct wall 11 forms an air guiding surface 115 of the air outlet duct.

[0083] Aiming at the problem of weak air guiding effect caused by the unreasonable positions of the air guiding surface 21 of the air deflector and the air guiding surface 115 of the air outlet duct, in this embodiment, the included angle between the air guiding surface 21 of the air deflector and the first air outlet duct extension surface 181 is the inclination angle α of the air guiding surface 21 of the air deflector, and the inclination angle α can change with the rotation of the air deflector 2; the included angle between the air guiding surface 115 of the air outlet duct and the second air outlet duct extension surface 182 is the inclination angle β of the air guiding surface 115 of the air outlet duct, and the inclination angle β remains unchanged, and the inclination angle β satisfies: 2° ≤ β ≤ 15°;

[0084] When the inclination angle α is negative, and the inclination angle α and the inclination angle β satisfy: β ≤ |α| ≤ 45°, the air deflector 2 is in the first air guiding position;

[0085] When the inclination angle α is positive, and the inclination angle α and the inclination angle β satisfy: 0 < α ≤ β, the air deflector 2 is in the second air guiding position;

[0086] Wherein, the first air outlet duct extension surface 181 is a plane passing through the rotation axis of the air deflector 2 and parallel to the thickness direction of the air outlet frame 1; when it is counterclockwise from the first air outlet duct extension surface 181 to the air guiding surface 21 of the air deflector, the inclination angle α is positive; when it is clockwise from the first air outlet duct extension surface 181 to the air guiding surface 21 of the air deflector, the inclination angle α is negative; the second air outlet duct extension surface 182 is a plane passing through the edge of the air guiding surface 115 of the air outlet duct close to the air inlet 16 of the air outlet frame and parallel to the thickness direction of the air outlet frame 1;

[0087] Preferably, the inclination angle β satisfies: 5° ≤ β ≤ 10°;

[0088] When the air deflector 2 is in the first air guiding position, the inclination angle α satisfies: -30° ≤ α ≤ -15°;

[0089] When the air deflector 2 is in the second air guiding position, the inclination angle α satisfies: 0° < α ≤ 2°.

[0090] In view of the problem that the inclination angle α of the air deflector 2 cannot be accurately controlled when there is no limiting structure during the rotation of the air deflector 2, in this embodiment, a duct limiting structure 141 is formed on the third duct wall 13 and / or the fourth duct wall 14; the duct limiting structure 141 includes an upper stroke limiting end 1411 and a lower stroke limiting end 1412, and the upper stroke limiting end 1411 and the lower stroke limiting end 1412 are located on the rotation path of the air deflector 2;

[0124] Embodiment 2

[0125] Different from Embodiment 1, in the rotation direction of the air guiding plate 2, the air guiding plate 2 further has a third air guiding position; when the air guiding plate 2 is in the third air guiding position, a third air guiding area is formed between the air guiding surface 21 of the air guiding plate and the air guiding surface of the air outlet duct, and the air in the third air guiding area can be discharged to the lower front of the air outlet 17 of the air outlet frame;

[0126] The end of the air guiding plate 2 close to the air outlet 17 of the air outlet frame is rotatably arranged on the side surface of the second air outlet duct wall 12 close to the first air outlet duct wall 11, and the air guiding plate 2 can be controlled to rotate up and down, and thus the air guiding plate 2 can be in the second air guiding position and the third air guiding position; when the air outlet 17 of the air outlet frame is in the open state, a air guiding surface 21 is formed on the side of the air guiding plate 2 close to the air guiding surface 115 of the air outlet duct;

[0127] An air guiding surface 115 of the air outlet duct is formed on the side surface of the first air outlet duct wall 11 facing the second air outlet duct wall 12, and the air guiding surface 115 of the air outlet duct is inclined downward relative to the thickness direction of the air outlet frame 1.

[0128] The casing air outlet may further include an upper air outlet on the casing, the main air duct includes an upper air duct, and the air outlet end of the upper air duct corresponds to the upper air outlet on the casing; the upper end of the front side wall 41 forms the upper air outlet on the casing, and an air outlet device is arranged between the upper air outlet on the casing and the upper air duct;

[0129] When the air guiding plate 2 is in the second air guiding position, the air outlet direction of the upper air outlet on the casing is directly in front of the upper air outlet 411 on the casing; the cabinet air conditioner can operate in the heating mode, can avoid the rapid upward floating of hot air, and can achieve rapid heating;

[0130] When the air deflector 2 is in the third air guiding position, the air outlet direction of the air outlet on the casing is the lower front of the air outlet 411 on the casing; the air can be timely sent to the area required by the user, solving the problem in the prior art that the air from the air outlet of the casing cannot be timely sent to the area required by the user, resulting in poor user experience.

[0131] Embodiment 3

[0132] As Figure 8a and Figure 8b shown, on the basis of Embodiment 1, when the air deflector 2 is in the first air guiding position, a part of the air in the air outlet duct 18 will enter the ventilation duct 45 through the first gap 43, resulting in eddy current and thus air volume loss. In this embodiment, it is proposed that the air outlet frame 1 further includes a sealing mechanism. The sealing mechanism is arranged at the first gap 43 and includes a first reel 61, a second reel 62, a torsion spring and a sealing cloth 63; the first reel 61 is rotatably arranged on the side of the first air outlet duct wall 11 facing the second air outlet duct wall 12, and the first reel 61 is close to the air inlet 16 of the air outlet frame. The first reel 61 can rotate relative to the first air outlet duct wall 11; one end of the torsion spring is connected to the side of the first air outlet duct wall 11 facing the second air outlet duct wall 12, and the other end of the torsion spring is connected to the first reel 61; the second reel 62 is rotatably arranged at the end of the air deflector 2 away from the first air outlet duct wall 11. The second reel 62 can rotate integrally with the air deflector 2 and can rotate relative to the air deflector 2.

[0133] One end of the sealing cloth 63 is wound on the first reel 61, and the other end of the sealing cloth 63 is wound on the second reel 62; when the air deflector 62 is controlled to rotate and the end of the air deflector 2 close to the air inlet moves away from the first air outlet duct wall 11, the sealing cloth 63 gradually unfolds and closes the first gap 43, and the torsion spring stores energy; the air in the air outlet duct 18 cannot enter the ventilation duct 45 through the first gap 43, avoiding air volume loss.

[0134] When the air deflector 2 is controlled to rotate and the end of the air deflector 2 close to the air inlet approaches the first air outlet duct wall 11, the torsion spring releases energy, and the end of the sealing cloth 63 close to the first reel 61 gradually winds on the first reel 61, and the unfolded area of the sealing cloth 63 gradually decreases.

[0135] In this way, by controlling the rotation of the air deflector 2, the air guiding surface 21 of the air deflector and the air guiding surface 115 of the air outlet duct cooperate to guide the air in the air outlet duct 18. At the same time, the air deflector 2 drives the sealing cloth 63 to unfold, and the sealing cloth 63 can close the first gap 43.

[0136] When the air deflector 2 is in the first air guiding position, the sealing cloth 63 unfolds and closes the first gap 43; the air in the air outlet duct 18 directly enters the first air guiding area 23, and the air in the first air guiding area 23 is discharged from the air outlet 17 of the air outlet frame and the air outlet of the casing to the upper front of the air outlet of the casing.

[0137] Example 4

[0138] As Figure 9a and Figure 9b shown, based on Example 1, when the air deflector 2 is in the first air guiding position, a part of the air in the air outlet duct 18 will enter the ventilation duct 45 through the first gap 43, resulting in eddy currents, and further causing air volume loss. In this embodiment, it is proposed that the front side wall 41 is formed with ventilation holes 412, and the positions of the ventilation holes 412 correspond to the positions of the end of the air deflector 2 close to the air outlet 17 of the air outlet frame; the ventilation holes 412 are communicated with the ventilation duct 45;

[0139] When the air deflector 2 is in the first air guiding position, a part of the air in the air outlet duct 18 enters the ventilation duct 45 through the first gap 43, and the air in the ventilation duct 45 can be directly discharged through the ventilation holes 412; another part of the air in the air outlet duct 18 directly enters the first air guiding area 23, and the air in the first air guiding area 23 is discharged from the air outlet 17 of the air outlet frame and the air outlet of the housing to the upper front of the air outlet of the housing;

[0140] The ventilation holes 412 discharge the air in the ventilation duct 45, which can prevent the air in the ventilation duct 45 from forming eddy currents and causing air volume loss;

[0141] Furthermore, the ventilation holes 412 are small holes or grille holes, and the hole depth direction of the ventilation holes 412 can be the horizontal direction, the vertical direction, or inclined with respect to the horizontal direction.

[0142] The exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, arrangements, or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
