All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the utility model. In the present utility model, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used to generally refer to the upper and lower positions of the device in actual use or operation, and specifically the orientation of the drawing figures; while "inner" and "outer" are for the outline of the device.
The embodiment of the utility model provides an air outlet structure and an air conditioner. The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
The air outlet structure of the embodiment of the utility model is arranged at the air outlet of the wall-mounted air conditioner.
Referring to fig. 1 and 2, the air outlet structure includes a grille 1 and an air deflector 2.
The grid 1 may comprise a number of spaced apart grids 11. Each louver 11 extends in the air outlet direction of the air outlet. The grid plates 11 are arranged in a stepped manner, so that the side edges of the grid plates 1 positioned at the inner side of the air outlet are arc-shaped side edges 12.
The air deflector 2 is rotatably arranged on the side of the arcuate side edge 12 of the grille 1. When the air deflector 2 rotates past the grille 1, the rotation route of the end of the air deflector 2 close to the grille 1 is matched with the shape of the arc-shaped side edge 12.
The air deflector 2 is configured such that when the air conditioner is in a cooling mode, the air deflector 2 rotates to expose the grille 1 such that the cool air flow is blown upward through the grille 1;
when the air conditioner is in a heating mode, the air deflector 2 rotates to shield the grille 1, so that hot air flows are blown downwards through the air deflector 2.
In some embodiments, the grille 1 may be fixedly disposed at the air outlet of the wall-mounted air conditioner, or may be rotatably connected to the air outlet of the wall-mounted air conditioner. The air deflector 2 is rotatably connected to the wall-mounted air conditioner for adjusting the opening/closing condition of the air outlet of the wall-mounted air conditioner so as to adjust the air outlet direction of the air flow.
In the case where the grill 1 is rotatably coupled to the inside of the air outlet of the air conditioner, the grill 11 can be opened by blowing of wind power.
In this embodiment, the grille 1 is fixedly arranged at the air outlet of the air conditioner, and the opening/closing condition of the air outlet of the air conditioner is adjusted by rotating the air deflector 2, so that the air is guided out from the grille 1 in the air cooling mode.
In this embodiment, the grille 1 includes a plurality of louvers 11 fixed at intervals in the vertical direction at the air outlet of the wall-mounted air conditioner. The air deflector 2 is positioned obliquely below the grille 1. The connecting line between the side edges of the grid plates 11 positioned at one side in the air conditioner is arc-shaped, namely, the side edge of the grid plate 1 positioned at the inner side of the air conditioner is arc-shaped side edge 12, so that the arc-shaped side edge 12 is matched with the rotating route of the end part of the air deflector 2, which is close to the grid plate 1, in the wall-mounted air conditioner.
Under the refrigeration working condition, the cold air needs to be blown to the high place and the far place as much as possible, in the embodiment, the air deflector 2 can rotate to the air outlet to shield, so that the cold air flow can only be blown out through the grille 1, and therefore, the cold air flow and the horizontal direction form a smaller included angle to flow; in the heating condition, the hot air needs to be blown to the lower position as much as possible. In this embodiment, due to the shape adaptation of the arc-shaped side edge 12 and the rotation route of the end of the air deflector 2 near the grille 1, the air deflector 2 can rotate to shield the grille 1, so that the hot air flows downwards, and therefore, the hot air flows at a larger included angle with the horizontal direction.
In one embodiment, the width of each louver 11 (i.e., the length in the air-out direction) gradually increases in the direction away from the air deflector 2.
The plurality of louver plates 11 may be parallel to each other; or, the grids 11 are inclined upward at different angles so that the ends of the grids outside the air outlet are higher than the ends of the grids inside the air outlet.
When the grids 11 are arranged in parallel, the intervals between any two adjacent grids 11 can be equidistant or not equidistant, so long as a gap is reserved between the grids 11.
In this embodiment, the plurality of louvers 11 are arranged in parallel, and both ends of each louver 11 are curved in a direction away from the air deflector 2. When the cool air is blown out through the grille 1, the cool air is blown out obliquely upward after passing through the grille 11 due to the coanda effect. Therefore, the flow direction of the wind is guided, so that the cold wind is blown higher and farther, and the problem of poor user experience caused by blowing to the user is avoided.
Further, referring to fig. 2, each louver 11 in the present embodiment includes two curved segments 21 curved upward and a straight segment connecting the two curved segments 21. The ends of the arcuate segments 21 remote from each other are upwardly curved to extend to increase the angle at which cold air is directed upwardly through the louvers 11, further increasing the coanda effect and allowing the cold air to be blown higher and farther. Meanwhile, due to the design of the two arc-shaped sections 21 which are bent upwards, the air quantity passing through the grille 1 can be increased, and the effect of increasing the air quantity is achieved.
Illustratively, the length of the arcuate segment 21 near the air outlet is greater than the length of the arcuate segment 21 near the air deflector 2 in order to extend the length of the louvers 11 beyond the air outlet to increase the coanda effect.
Illustratively, the angle between the extension of the line connecting the two ends of each arcuate segment 21 and the straight segment is no more than 30 °. The included angles of the arc-shaped sections 21 below all refer to included angles between the extension line of the arc-shaped sections 21 and the straight line section, wherein the included angle of the arc-shaped sections 21 close to the air deflector 2 can be larger than the included angle of the arc-shaped sections 21 outside the air conditioner so that the air quantity enters between the grid plates 11, and meanwhile, the conditions that the included angles of the arc-shaped sections 21 and the straight line section outside the air conditioner are overlarge, the air quantity is blown upwards and the distance of blowing of the air quantity is reduced are reduced.
Further, referring to fig. 1, the air deflector 2 is bent and arranged in the air outlet of the air conditioner, and the rotation angle of the air deflector 2 in the air outlet of the air conditioner is smaller than 360 degrees, so that the space occupied in the air conditioner due to excessive rotation of the air deflector 2 is further reduced.
Specifically, both ends of the air guide plate 2 are bent toward the inside of the air conditioner. The rotating track of the end part of the air deflector 2 is arc-shaped and just rotates in the arc-shaped side edge 12, so that the rotating path of the air deflector 2 is more attached to the arc-shaped side edge 12.
Further, referring to fig. 3, when the air deflector 2 rotates to be parallel to the grid plate 11, a first air outlet duct 22 is formed between the top wall of the air deflector 2 and the air conditioner, and the grid plate 11 is located in the first air outlet duct 22. A second air outlet duct 23 is formed between the bottom wall of the air deflector 2 and the wall-mounted air conditioner. At this time, the second air outlet duct 23 may be omitted, so that the cool air is blown out from above the air deflector 2 and between the grid plates 11.
In this embodiment, the air outlet flow of the first air outlet duct 22 is greater than the air outlet flow of the second air outlet duct 23, that is, the distance between the air deflector 2 and the grid plate 11 is greater than the distance between the air deflector 2 and one side of the air conditioner wall-mounted unit away from the grid 1, so that most of cold air is blown out from the upper part of the air deflector 2 and the grid plate 11 when cold air is discharged, and the cold air is blown out at a higher and more distant angle. A small part of cold air enters the second air outlet duct 23, and at the moment, the cold air entering the second air outlet duct 23 is influenced by the coanda effect due to the shape of the air deflector 2, and the cold air coming out of the second air outlet duct 23 is still blown out at an inclined upward angle after passing through the lower part of the air deflector 2, so that the cold air blown out of the first air outlet duct 22 and the second air outlet duct 23 are all blown out in an inclined upward direction.
Referring to fig. 3 and 4, in the refrigerating state: when the air deflector 2 rotates counterclockwise according to the rotation axis, and the air deflector 2 rotates by a certain angle a (the value range of a is 28 degrees to-68 degrees, as shown in fig. 4, the air deflector rotates counterclockwise, the angle takes the horizontal direction as the reference, and the clockwise direction is the positive direction), the value of the embodiment is-11 degrees.
At this time, the direction of the air flow generated by the air conditioner is shown in fig. 3, and the air flow can move along the air deflector 2 and the grille 1 due to the diversion effect of the air deflector 2 and the grille 1, so that the cold air is blown higher and farther, and the problem of poor user experience caused by direct blowing to the user is avoided; and cold air utilizes the density difference to slowly subside under the action of gravity, cools down indoor environment, and the wind sense that user experience was little this moment, and the travelling comfort is high.
Referring to fig. 5 and 6, in the heating state: the air deflector 2 rotates clockwise according to the rotation axis, when the air deflector 2 rotates a certain angle B (the value range of B is 28-190 degrees, as shown in fig. 5, the angle is clockwise rotated by taking the horizontal direction as a reference, and the clockwise direction is positive), the value of the embodiment is 100 degrees, at the moment, the air flow direction is as shown in fig. 6, and the hot air flows upwards under the action of the buoyancy lift force due to the fact that the hot air flows pass through the air deflector 2, so that the temperature of the indoor environment is raised by utilizing the density difference. Thus, the carpet-type air supply is realized, and the comfort is improved.
Referring to fig. 7, when the air deflector 2 rotates to be smoothly connected with the air duct wall on the side of the air deflector 2 away from the grille 1, a minimum air outlet is formed between the air deflector 2 and the grille 1. When the air deflector 2 rotates to the minimum air outlet position, air flow can be blown out through the minimum air outlet, the air pressure of air outlet from the grille 1 is reduced, meanwhile, wind noise is reduced, and the effect that noise is minimum after the air deflector 2 opens the minimum air outlet is achieved.
Further, in order to better implement the air outlet structure in the embodiment of the present utility model, on the basis of the air outlet structure, the embodiment of the present utility model further provides an air conditioner, where the air conditioner includes the air outlet structure in any one of the embodiments, and the grille 1 and the air deflector 2 in the exemplary air outlet structure are both located at the air outlet of the air conditioner. Referring to fig. 7 and 8, the air conditioner includes a base 3, a middle frame 4, a panel 5, and an air outlet formed between the panel 5 and the base 3, wherein a through-flow fan 41 rotates in the middle frame 4. The air conditioner in the embodiment of the utility model has all the beneficial effects of the air outlet structure because the air outlet structure in the embodiment is arranged, and the detailed description is omitted.
It should be noted that the surface appearance of the grille 1 is not limited to the horizontal and vertical shapes in fig. 8, and various shapes with hollowed-out structures can be realized, such as V-shape, diamond shape, pattern or other patterns; second, the surface appearance may also be finished using secondary processes, such as spraying, plating, etc., to achieve a cosmetic appearance. The position of the grid 1 is determined by the position of the upper edge of the air deflector 2, for example, when the upper edge of the air deflector 2 is matched with the middle frame 4 or the cover plate, the position matched with the upper edge of the air deflector 2 is made into a grid 1 shape, and the design is not limited to the design on the panel 5.
