DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. As shown in FIG. 1, a vertical air conditioner according to an embodiment of the present invention includes: a casing 10, which may be cylindrical, internally formed with a cavity, and can accommodate components such as an evaporator (not shown), and the casing 10 Rotating; air duct 20, disposed in the outer casing 10, located in a cavity formed inside the outer casing 10, the air duct 20 is adjacent to the evaporator; the vertical air conditioner has a center line AA, and the center line AA is a vertical air conditioner The geometric center line of the outer casing 10, the air outlet 100 is disposed on the outer casing 10 and communicates with the air duct 20, the air outlet 100 of the vertical air conditioner is vertically disposed, and can be rotated out of the wind; the outer casing 10 of the vertical air conditioner is on the front side The position, that is, the position when the outer casing 10 of the vertical air conditioner is not rotated, is also the position of the outer casing 10 of the vertical air conditioner facing the air outlet 100; the grill 110 is disposed at the air outlet 100 of the outer casing 10. As shown in FIG. 2, the grille 110 covers the outside of the air outlet 100, and ensures that when the grille 110 rotates with the outer casing 10, the grille 110 can be placed outside the air outlet 100 to realize any position where the outer casing 10 rotates. Can guide or sweep the wind. As shown in FIG. 3, the grille 110 includes vertically disposed vertical bar grills 111, which are generally elongated, and can be vertically guided by the rotation of the outer casing 10. The vertical bar grill 111 has a curved air outlet surface. Since the vertical bar grille has a curved air outlet surface, when the wind coming out of the air duct 20 passes through the grille, the wind direction of the air outlet surface of different bending angles is different, and the center line AA of the vertical air conditioner can be clamped. The wind direction blown out in the air duct of the corner is adjusted to achieve uniform wind output and symmetrical wind effect. Therefore, the invention breaks through the traditional vane air guiding structure or sweeping structure, and overcomes the existing air outlet range of the vertical air conditioner. The problem of uneven wind sweep caused by the asymmetry of the center of the whole machine and the complicated structure and high cost of the blade type wind guiding structure or the sweeping wind structure achieve the uniform effect of the air outlet and improve the comfort of use of the air conditioner. The vertical bar grill 111 has a first end adjacent to the air duct 20 and a second end remote from the air duct 20, and the air outlet surface includes a first air surface 113 at the first end and a second air surface 117 at the second end. The first wind surface 113 and the second wind surface 117 form a bend angle. The first air outlet surface 113 is located adjacent to the air duct 20 and communicates with the air duct 20, and the second air outlet surface 117 is adjacent to the outer side of the outer casing 10. The first air outlet surface 113 and the second air outlet surface 117 may be located in the same plane, or may be located in different planes to form a certain angle. When the first air outlet surface 113 and the second air outlet surface 117 are located in the same plane, the vertical bar grid 111 further includes a straight plate shape or a straight piece vertical bar grid. The first air outlet surface 113 and the second air outlet surface 117 of the straight or straight vertical grid and/or the folded vertical grid can guide the air outlet 100, so the present invention breaks through the conventional blade. Type of wind guiding structure or sweeping structure, no need to set special rotation The mechanism drives the grille 110 to rotate, and the wind can be swept as long as the outer casing 10 rotates, which overcomes the problems that the existing vertical air conditioner adopts a blade type air guiding structure or a complicated wind sweeping structure and high cost. Further, the vertical bar grille 111 is a plurality of, and the plurality of vertical bar grilles form a plurality of bent air outlet surfaces, and the angle of each air outlet surface is adjusted, so that the sweeping wind can be uniform. Further, as shown in FIG. 3, the grill 110 further includes a horizontally disposed crossbar grille 112. In this way, wind guiding at different levels of height can be achieved, and the strength of the grid 110 is increased. Further, the plurality of horizontal bar gratings 112 are evenly distributed to make the air out of uniformity, and the horizontal bar grating 112 and the vertical bar grating 111 intersect in a mesh shape to form uniform wind guiding in different areas. Further, the grid 110 and the outer casing 10 are of a unitary structure, for example, formed by injection molding, so that the processing is easy and the strength is high. Further, as shown in FIG. 4, the plurality of vertical bar grids are in the shape of a flap or a curved plate, for example, the vertical grille has an angular shape or a curved curved first wind surface 113 and a second air surface. 117 are not on the same plane, and the two form a bend angle. The vertical grid of this shape can significantly change the direction of the wind and is sleek. Further, the bending angle of each of the plurality of vertical bar grids is between 0 and 15 degrees, and preferably, the bending angle of the vertical bar grid is between 5 and 10 degrees. When the air coming out of the duct passes through the grille, the vertical strips at different bending angles are guided at different angles. Through the experimental measurement, the bending angle of the vertical bar is adjusted, so that when the style grid is on the front side, the air outlet range of the whole machine is symmetrical, so as to achieve a better air blowing effect. Further, the air duct 20 forms an angle with the center line AA of the vertical air conditioner, and when the outer casing 10 is at the front position, the wind direction of the plurality of vertical grids is parallel to the center line AA of the vertical air conditioner. For example, when the outer casing 10 is in the front position, the wind direction of the plurality of vertical grids can be parallel to the center line AA of the vertical air conditioner by making the second wind outlet surfaces 117 parallel to the center line AA. The effect of the air outlet of the vertical air conditioner is symmetrical, and the user's comfort is increased. Further, as shown in FIG. 4, a plurality of vertical bar grids 111 are equally spaced on the outer casing 10 to make the air out uniform. In addition, the shape of each of the vertical bar grids 111 may be the same, and may be arranged in parallel to facilitate fabrication. As shown in FIG. 5, when the outer casing 10 is rotated to the right, the vertical grille 111 acts to make the wind direction to the right, and the right wind is swept; as shown in FIG. 6, when the outer casing 10 is rotated to the left, the vertical bar is passed. The function of the grille 111 is such that the wind direction is leftward, the left wind is swept, and the air guiding action through the vertical grille 111, although the air duct 20 forms an angle with the center line AA of the vertical air conditioner, can still be realized. Make the right and left sweeps even. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention.
