Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0037] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] See also Figure 1 and Figure 2 An embodiment of the present invention provides an air guide structure 100, which is applied to a vertical air conditioner 200. The vertical air conditioner 200 includes an air outlet 201. The air guide structure 100 includes at least one layer of cylindrical air guide member group 101. The cylindrical air guide member group 101 includes at least one pair of cylindrical air guide members 1011. The pair of cylindrical air guide members 1011 includes two cylindrical air guide members 10111 rotatably arranged at the air outlet 201. The two cylindrical air guide members 10111 are used to realize compressed wind, concentrated wind or dispersed wind when rotating in a specified rotation direction.

[0039] In this embodiment, a plurality of cylindrical air guides 10111 are arranged at the air outlet 201, and the rotation direction and speed of the cylindrical air guides 10111 are controlled to realize a variety of air supply modes such as compressed air, concentrated air or dispersed air at different angles. This not only solves the problem that the existing vertical air conditioner has a single air guide structure, which easily causes aesthetic fatigue to users, and the air outlet 201 has a black hole, affecting the appearance of the product; it also solves the problem that the air outlet 201 has a single air supply form and it is impossible to select different air supply forms according to user needs, resulting in poor cooling or heating comfort, thereby improving the user experience.

[0040] In one embodiment, two cylindrical air guides 10111 are arranged in parallel. In this embodiment, the two cylindrical air guides 10111 are arranged in parallel, which means that their axes are on the same straight line or parallel to each other, which can ensure that the airflow is evenly distributed when passing through the cylindrical air guides 10111, avoiding the situation where the local airflow is too strong or too weak. According to the user's requirements for the air supply direction, wind speed and air supply range of the air conditioner, the angle and rotation speed of the cylindrical air guide 10111 can be adjusted to meet the user's different usage scenarios and needs.

[0041] Furthermore, the axial direction of the two cylindrical air guides 10111 is perpendicular to the air outlet direction of the air outlet 201. Figure 1 and Figure 3 It can be seen that the length direction (i.e., the axial direction) of the two cylindrical air guides 10111 is perpendicular to the air outlet direction of the air outlet 201, so that the airflow can realize the conversion of the air outlet mode through the rotation of the cylindrical air guide 10111; at the same time, it ensures that the airflow can directly and effectively contact the cylindrical air guide 10111 when leaving the air outlet 201, and change its flow direction and speed by adjusting the shape and angle of the air guide, and by controlling the rotation direction and speed of the cylindrical air guide 10111, free switching of various air supply modes such as compressed air, concentrated air and dispersed air can be realized, while improving the comfort of air conditioning and improving user experience.

[0042] Further, such as Figure 2 As shown, the cylindrical air guide member group 101 is provided with multiple layers along the air outlet direction of the air outlet 201. In this embodiment, multiple layers of cylindrical air guide members 10111 are provided along the air outlet direction of the air outlet 201, the number of layers N of the cylindrical air guide members 10111 is greater than or equal to 2, and the spacing between two adjacent layers of cylindrical air guide members 10111 is the same.

[0043] In this embodiment, the arrangement of the multi-layer cylindrical air guide member group 101 can more accurately control the direction and intensity of the airflow, and can more effectively utilize the air guide area of ​​the air outlet 201, increase the number of airflow outlets and the distribution range, and help improve the air guide efficiency, so that the air conditioner can reach the ideal temperature and humidity conditions in a shorter time. Specifically, by adjusting the angle and rotation speed of the air guide members of different layers, complex airflow patterns can be achieved, such as three-dimensional air supply, directional air supply, etc.

[0044] It should be noted that the cylindrical air guide assembly 101 can be arranged in a single layer or in multiple layers. In a small or compact vertical air conditioner 200, or when the user does not have particularly high requirements for the air supply direction, the single-layer cylindrical air guide assembly 101 can also achieve multiple air supply modes, and the two cylindrical air guides 10111 in the single-layer cylindrical air guide assembly 101 are symmetrical and roughly evenly arranged; the multi-layer cylindrical air guide assembly 101 can be used in a large or high-end vertical air conditioner 200, or when the user has particularly high requirements for the air supply effect, the multi-layer cylindrical air guide assembly 101 can better meet the needs and help improve the cooling effect or heating effect of the air conditioner.

[0045] Specifically, Figure 2As shown, each layer of cylindrical air guide member group 101 includes multiple pairs of cylindrical air guide members 10111. In this embodiment, multiple pairs of cylindrical air guide members 10111 on each layer can more effectively utilize the air guide area of ​​the air outlet 201, increase the number of air flow outlets and the distribution range, help improve the air guide efficiency, and enable the air conditioner to more accurately control the flow direction, intensity and distribution of the air flow, and realize a more complex air supply mode.

[0046] Further, such as Figure 1 As shown, each cylindrical air guide 10111 is connected to a control device 203, and the control device 203 is electrically connected to the main control of the vertical air conditioner 200. In this embodiment, the control device 203 can be a motor, and the air guide is arranged in an axial direction perpendicular to the air outlet direction, and the air guide can be driven to rotate by a motor or other driving mechanism. Each pair of cylindrical air guides 1011 can work independently or in coordination to achieve a complex air supply mode.

[0047] Further, such as Figure 4 As shown, the air outlet 201 includes an upper air outlet 2011 and a lower air outlet 2012 , and each cylindrical air guide 10111 of the upper air outlet 2011 is arranged along the horizontal direction of the upper air outlet 2011 ; each cylindrical air guide 10111 of the lower air outlet 2012 is arranged along the vertical direction of the lower air outlet 2012 .

[0048] In the existing vertical air conditioner 200, the vertical air conditioner 200 with upward and downward air outlets usually has an air outlet 201 at the top and bottom of the air conditioner, so its air supply method includes a single upward air outlet method and an upward and downward air outlet method. However, since the structure of the downward air outlet 201 is fixed, the air supply form is single and cannot meet the user's comfort needs in different scenarios.

[0049] Therefore, in this embodiment, Figure 3 It can be seen that each cylindrical air guide 10111 of the upper air outlet 2011 is arranged along the horizontal direction of the upper air outlet 2011, so that when the airflow passes through the cylindrical air guide 10111, its surface rotates and drives the surrounding air to move together, and the cylindrical air guide 10111 guides the airflow to deflect forward to achieve the air pressure function. Each cylindrical air guide 10111 of the lower air outlet 2012 is arranged along the vertical direction of the lower air outlet 2012. At the lower air outlet 2012, the airflow is guided to gather in the middle by the cylindrical air guide 10111 to achieve the wind gathering function. The airflow can also be guided to diverge to both sides by the cylindrical air guide 10111 to achieve the wind dispersion function, which is particularly suitable for occasions where the ground or low areas need to be heated or cooled. Therefore, the air supply mode of upper air outlet compressed air, lower air outlet dispersed air and gathered air is adopted to make the air guide efficiency higher and further improve the user experience.

[0050] In a specific embodiment, Figure 2 As shown, a minimum control unit 300 is defined when controlling the rotation direction and speed of the cylindrical air guide 10111. Since the two cylindrical air guides 10111 are symmetrically and roughly evenly distributed, the cylinders on the left and right sides are used as the minimum control unit 300 in consideration of their symmetry. For example, if the cylinders are distributed in 2 rows and 2 columns, the cylinders in 2 rows and 1 column on the left and right sides are used as the minimum control unit 300. Figure 3 It is a side view of a vertical air conditioner 200. The two cylindrical air guides 10111 in the figure are a minimum control unit 300. When the left and right cylinders rotate clockwise, the cylindrical air guides the airflow to deflect forward to achieve a compressed air function. At the same time, different compressed air angles can be achieved by adjusting the rotation speed of the cylinder. That is to say, the compressed air function can be achieved when the rotation direction of the minimum control unit 300 is the same. Figure 5 and Figure 6 This is a simulation diagram comparing the wind speed of the cylindrical air guide before and after rotation. Figure 6 It can be seen that when the left and right cylinders rotate clockwise, the cylindrical air guide guides the airflow to deflect forward, and the wind speed is higher.

[0051] It should be noted that the purpose of compressed air is to send air forward. If the air is not compressed, the air flow will blow directly to the ceiling, which cannot meet the needs of users. Therefore, in order to achieve the compressed air function, it is necessary to ensure that the rotation directions of the cylindrical air guides 10111 on the left and right sides are the same. If the rotation speeds of the two cylindrical air guides 10111 are different, for example, Figure 3 In the middle, the left side has a high speed and the right side has a low speed, which can realize the wind gathering function; the left side has a low speed and the right side has a high speed, which can realize the wind dispersion function.

[0052] Further, still taking the single-layer two cylindrical air guides 10111 as an example, Figure 7 As shown, it is a top view of the lower air outlet of the vertical air conditioner 200. From the top view, when the cylindrical air guide 10111 on the upper side rotates clockwise and the cylindrical air guide 10111 on the lower side rotates counterclockwise, the cylindrical air guide 10111 guides the air flow to gather in the middle to achieve the wind gathering function. In this mode, the air supply distance is long, and the remote temperature of the vertical air conditioner 200 can be quickly controlled. Figure 8 It is a simulated cloud diagram of wind speed when the cylindrical air guide rotates in the wind gathering mode; Fig. 9 As shown, it is also a top view of the lower air outlet of the vertical air conditioner 200. From the top view, the cylindrical air guide 10111 on the upper side rotates counterclockwise, while the cylindrical air guide 10111 on the lower side rotates clockwise. The cylindrical air guide 10111 guides the airflow to diverge to both sides to achieve the wind dispersion function. This mode reduces the near-end wind speed without reducing the air volume, which can reduce the blowing feeling in this area and improve the user's comfort. Fig.10 It is a simulated cloud diagram of wind speed when the cylindrical air guide rotates in the scattered wind mode.

[0053] Generally speaking, when the upper air outlet realizes the air pressure function or mode, the two cylindrical air guide members in the pair of cylindrical air guide members rotate in the same direction; when the lower air outlet realizes the wind gathering function, the two cylindrical air guide members in the pair of cylindrical air guide members rotate toward each other along the air outlet direction, for example Fig.11 In the embodiment, the upper cylindrical air guide piece should rotate towards the lower cylindrical air guide piece, that is, rotate clockwise, and the lower cylindrical air guide piece should rotate towards the upper cylindrical air guide piece, that is, rotate counterclockwise, and the two form an effect of gathering the wind direction. When the lower air outlet realizes the wind dispersion function, the rotation direction of the two cylindrical air guide pieces in the pair of cylindrical air guide pieces is to rotate away from each other along the air outlet direction, such as Fig.12 In the embodiment, the cylindrical air guide member on the upper side should rotate in the direction away from the cylindrical air guide member on the lower side, that is, rotate counterclockwise, and the cylindrical air guide member on the lower side should rotate in the direction away from the cylindrical air guide member on the upper side, that is, rotate clockwise, and the two form an effect of diffusing the wind direction.

[0054] Further, such as Fig.11 As shown, the installation elevation angle of a pair of cylindrical air guides 1011 with respect to the horizontal direction ranges from 0° to 45°. In this embodiment, taking a pair of single-layer cylindrical air guides 1011 arranged at the upper air outlet as an example, the installation elevation angle of the cylindrical air guide 10111 with respect to the horizontal direction is a (the angle between a straight line passing through the center points of a pair of cylinders and the horizontal direction). Considering the appearance effect when viewed from the front, the value range of the cylindrical installation elevation angle a is between [0°, 45°]. In order to avoid interference between the structure of the cylindrical air guide 10111 and the body of the vertical air conditioner 200 and also for the convenience of installation, the gap between the outermost edge of the cylindrical air guide 10111 and the wall of the body should be no less than 3 mm, that is, ((Cc+0.5d)cos a-0.5d)≥3mm, where d is the diameter of the cylindrical air guide 10111. In order to determine the above-mentioned gap, a straight line can be drawn along the installation elevation of the cylindrical air guide 10111. This straight line passes through the center of the cylindrical air guide. The intersection of this straight line and the edge of the cylindrical air guide close to the fuselage wall is c, and the intersection of this straight line and the fuselage wall is C. Cc is the distance from point C to point C.

[0055] Furthermore, the diameter of the cylindrical air guide 10111 is between 20 and 200 mm. In this embodiment, taking a pair of single-layer cylindrical air guides 1011 as an example, the fuselage length of the vertical air conditioner 200 is AC, and the diameter of the cylindrical air guide 10111 is d. Usually, the fuselage length AC of the vertical air conditioner 200 has a value range of 300 to 500 mm. If the diameter d of the cylindrical air guide 10111 is too small, if its surface is to reach a certain speed, the rotation speed of the cylindrical air guide 10111 needs to be increased very high. If the diameter d of the cylindrical air guide 10111 is too large, the flow passage area of ​​the air outlet 201 is too small, and the air outlet resistance is too large. Considering the above, the diameter d of the cylindrical air guide 10111 is in the range of 20 to 200 mm.

[0056] Further, such as Fig.12 and Fig.13 As shown, the surface of the cylindrical air guide 10111 is provided with a pit structure 101111 and / or a convex structure 101112. In the present embodiment, the pit structure 101111 and the convex structure 101112 are small depressions or holes formed on the surface of the cylindrical air guide 10111, such as hemispherical grooves or hemispherical protrusions. In other embodiments, the pit structure 101111 and / or the convex structure 101112 can also be a regular or irregular structure, such as a square structure. The pit structure 101111 and / or the convex structure 101112 provided on the surface of the cylindrical air guide 10111 enhances the roughness of its surface, can more effectively drive the movement of the surrounding airflow, and makes the airflow more easily disturbed and dispersed when passing through, and this disturbance helps to enhance the turbulence of the airflow and improve the air guiding efficiency of the cylindrical air guide 10111.

[0057] The embodiment of the present invention further provides a vertical air conditioner 200, comprising the air guide structure 100 as described in any one of the above items.
