[0037] Embodiment one

[0038] Referring toFigures 1-9 As shown, the embodiment discloses an air supply device 1 applied to an air outlet 21 of an air conditioner 2 to realize multi-dimensional air outlet of the air conditioner 2.

[0039] The air supply device 1 of the embodiment comprises a first air sweeping plate 11 and a plurality of air supply mechanisms 12. The first air sweeping plate 11 is rotationally arranged at the air outlet 21, and the rotation center axis of the first air sweeping plate 11 is parallel to the length direction of the first air sweeping plate 11, and the rotation center axis of the first air sweeping plate 11 is transversely arranged. The plurality of air supply mechanisms 12 are linearly distributed along the length direction of the first air sweeping plate 11. The air supply mechanism 12 comprises a second air sweeping plate 121, a fan assembly 122 and a swing driving element 123. The fan assembly 122 is connected to the second air sweeping plate 121, the second air sweeping plate 121 is rotationally connected to the first air sweeping plate 11, and the swing driving element 123 is used to drive the second air sweeping plate 121 to rotate. The rotation center axis of the second air sweeping plate 121 is vertically arranged.

[0040] In specific implementation, the two ends of the first air sweeping plate 11 are rotationally connected to the two ends of the air outlet 21, so as to accommodate more air supply mechanisms 12. In the embodiment, the air outlet direction of the fan assembly 122 corresponds to the arrangement of the air outlet 21, so that the fan assembly 122 can uniformly send out the cold air or hot air generated by the air conditioner 2 to each corner of the room; the rotation center axis of the first air sweeping plate 11 is horizontally arranged, so that the first air sweeping plate 11 can rotate upward or downward to drive the fan assembly 122 to swing upward or downward; the rotation center axis of the second air sweeping plate 121 is perpendicular to the rotation center axis of the first air sweeping plate 11, i.e. the rotation center axis of the second air sweeping plate 121 is vertically arranged, so that the second air sweeping plate 121 can rotate left or right to drive the fan assembly 122 to swing left or right.

[0041] The air supply device 1 of the embodiment uses independent fan assemblies 122 to replace the air sweeping blades 1221, so that each fan assembly 122 can independently blow air, improving the air supply efficiency; by arranging the second air sweeping plate 121 and the swing driving element 123, the swing direction of each fan assembly 122 is independently controlled, so that each fan assembly 122 can swing left or right, realizing flexible transverse air sweeping control, which is helpful for the air conditioner 2 to blow air left and right at the same time; by arranging a plurality of air supply mechanisms 12 on the first air sweeping plate 11, the first air sweeping plate 11 drives the fan assembly 122 to rotate upward or downward to realize longitudinal air sweeping function, thereby realizing multi-dimensional air flow control of the air conditioner 2, so that the air supply device 1 can comprehensively adjust the air direction in the upward, downward, leftward and rightward directions, providing more personalized and accurate air supply experience for the user, which is helpful to ensure the uniformity of air distribution, thereby helping to realize soft air supply, and can significantly improve the heat exchange efficiency and cooling effect, effectively reducing the energy consumption on the premise of ensuring user comfort, realizing the double optimization of energy saving and comfort.

[0042] Specifically, the fan assembly 122 comprises: fan blades 1221 and a blower driving element 1222; the fan blades 1221 are rotationally connected to the second sweeping panel 121, the axis of the fan blades 1221, the rotation center axis of the second sweeping panel 121 and the rotation center axis of the first sweeping panel 11 are perpendicular to each other; the blower driving element 1222 is used to drive the fan blades 1221 to rotate along the axis of the fan blades 1221. Each fan blade 1221 is equipped with an independent blower driving element 1222, which can drive the fan blades 1221 to rotate at high speed, thereby generating strong airflow, and thus improving the air supply efficiency of the air supply device 1, and each blower driving element 1222 can be independently controlled, which can increase or decrease the wind speed of the fan blades 1221, or start or stop the fan blades 1221, so as to allow the user to customize the air supply mode according to his own needs. The main air outlet direction of the fan blades 1221 is the axis direction of the fan blades 1221, the axis of the fan blades 1221, the rotation center axis of the second sweeping panel 121 and the rotation center axis of the first sweeping panel 11 are perpendicular to each other, which ensures that the rotation of the second sweeping panel 121 or the first sweeping panel 11 does not interfere with the air outlet of the fan blades 1221, and at the same time improves the compactness of the structure of the air supply device 1, and ensures the stable operation of the air supply device 1.

[0043] Specifically, the fan blades 1221 are axial flow fan blades. When the blower driving element 1222 drives the axial flow fan blades to rotate, the axial flow fan blades suck air from the back air inlet and discharge it along the axis direction, so that the air outlet direction of the fan blades 1221 is concentrated and controllable, and the rotation of the second sweeping panel 121 can easily change the air outlet direction of the fan blades 1221, thereby realizing flexible adjustment of the air outlet direction; and the axial flow fan blades have the characteristics of large air volume, low air pressure, high efficiency, energy saving and low noise, which brings a comfortable use experience to the user, and further reduces energy consumption, improves the energy efficiency ratio of the air conditioner 2, and makes the air conditioner 2 system more energy-saving and environmentally friendly during operation.

[0044] In this embodiment, the blower driving element 1222 is a direct current motor. The direct current motor has high efficiency, and under the same input power, it can provide larger air volume for the fan blades 1221, thereby meeting higher air supply requirements; the speed, direction and torque of the direct current motor can be accurately controlled by adjusting the voltage, current and electrode polarity, so as to adjust the air supply volume according to the actual needs; in addition, the direct current motor runs smoothly, has little wear and low noise, avoids large noise during operation of the air supply device 1, provides a better use experience for the user, at the same time, the service life of the direct current motor is also higher, reduces the trouble and cost caused by frequent replacement of the blower driving element 1222, and thus can ensure the stability and persistence of the fan blades 1221 during long-time operation.

[0045] It can be understood that in other embodiments, a stepping motor or a servo motor can be used to replace the direct current motor according to actual needs.

[0046] Specifically, the second sweeping panel 121 extends along the width direction of the first sweeping panel 11, the air blower driving member 1222 is connected to the second sweeping panel 121, and the axis of the fan blade 1221 is perpendicular to the second sweeping panel 121. The second sweeping panel 121 and the fan blade 1221 are vertically arranged, and under the driving action of the swing driving member 123, the second sweeping panel 121 is parallel to or forms a certain angle with the first sweeping panel 11 to realize that the air outlet 21 of the fan blade 1221 directly blows air forward or swings left and right. The air blower driving member 1222 is installed on the second sweeping panel 121 and can rotate with the second sweeping panel 121, ensuring that the fan blade 1221 can still maintain a stable rotating speed and wind power output during swinging, simplifying the structure of the air supply mechanism 12, avoiding the overlong wires between the fan blade 1221 and the air blower driving member 1222 from being easily entangled, improving the structural compactness of the air supply mechanism 12, and further reducing the maintenance difficulty and cost.

[0047] Specifically, the first sweeping panel 11 is provided with a plurality of mounting holes 111, and the plurality of mounting holes 111 are linearly distributed along the length direction of the first sweeping panel 11; and the second sweeping panel 121 is rotationally connected to the mounting hole 111. The arrangement of the mounting hole 111 enables the fan assembly 122 to be embedded in the first sweeping panel 11, making the structure of the air supply device 1 more compact and stable, reducing the occupied area of the air supply device 1, improving the space utilization, and effectively avoiding the interference of the first sweeping panel 11 with other structures in the air conditioner 2 during rotation.

[0048] Specifically, the swing driving member 123 is a motor, the motor is connected to the first sweeping panel 11, the output shaft of the motor extends along the width direction of the first sweeping panel 11 and is connected to the second sweeping panel 121. The motor as the swing driving member 123 can provide stable and easy-to-control driving force for the second sweeping panel 121, so that the second sweeping panel 121 can accurately swing left and right, improving the automation degree and control accuracy of the air supply device 1, so as to realize different air supply effects by adjusting the parameters of the motor. The output shaft of the motor is connected to the second sweeping panel 121, which can make the second sweeping panel 121 rotate around the output shaft of the motor as the rotation center axis, so that the rotation center axes of the first sweeping panel 11 and the second sweeping panel 121 are perpendicular to each other and do not interfere with each other, so that the first sweeping panel 11 and the second sweeping panel 121 can control the up-down and left-right rotation of the fan assembly 122, respectively, improving the adjustment flexibility of the air supply direction and meeting the needs of users for various air supply directions and modes.

[0049] In the embodiment, the swing driving member 123 is a stepper motor. The stepper motor can control the rotation angle of the second air sweeping plate 121 accurately in fixed steps, which helps the user to set a specific air supply angle according to the need, and also helps to automatically adjust the air supply direction according to the environmental conditions, thereby improving the self-definition, intelligence and automation of the air supply device 1.

[0050] It can be understood that in other embodiments, a servo motor, a rotary cylinder or other driving members can be used to replace the stepper motor according to actual needs.

[0051] Specifically, the second air sweeping plate 121 is further provided with a rotating shaft 1211 at the end away from the motor output shaft, and the mounting hole 111 is provided with a shaft hole corresponding to the rotating shaft 1211, and the rotating shaft 1211 is arranged in the shaft hole (not shown). The rotating shaft 1211 and the output shaft of the swing driving member 123 are arranged at two ends of the second air sweeping plate 121 respectively, so that the second air sweeping plate 121 can rotate more stably, and the cooperation of the rotating shaft 1211 and the shaft hole can reduce the friction and wear during the rotation of the second air sweeping plate 121, thereby improving the durability and stability of the air supply device 1 and prolonging the service life of the air supply device 1.

[0052] Specifically, the air supply device 1 of the embodiment further comprises a rotation driving member 13. The rotation driving member 13 is used to drive the first air sweeping plate 11 to rotate. The rotation center axis of the first air sweeping plate 11 is parallel to the length direction of the first air sweeping plate 11. The rotation driving member 13 drives the first air sweeping plate 11 to rotate up and down, and the first air sweeping plate 11 drives the second air sweeping plate 121 to rotate up and down, and the second air sweeping plate 121 drives the fan assembly 122 to rotate up and down. The rotation driving member 13 and the swing driving member 123 are independent of each other, so that the left-right rotation and the up-down rotation of the fan assembly 122 do not interfere with each other, which helps the fan assembly 122 to rotate left and right while rotating up and down, and helps to increase the air supply effect and the dispersion area of the air, thereby increasing the types of air supply modes, so that the user can adjust the rotation speed and swing angle of the fan blade 1221 through the intelligent control system, and realize diversified use requirements such as soft wind, strong wind, and fixed-point air supply.

[0053] In the embodiment, the rotation driving member 13 is a stepper motor. The stepper motor can control the rotation angle of the first air sweeping plate 11 accurately in fixed steps, which helps the user to set a specific air supply angle according to the need, and also helps to automatically adjust the air supply direction according to the environmental conditions, thereby improving the self-definition, intelligence and automation of the air supply device 1.

[0054] It can be understood that in other embodiments, a servo motor, a rotary cylinder or other driving members can be used to replace the stepper motor according to actual needs.

[0055] Specifically, the air supply device 1 of the embodiment further comprises a wind shield 14, the two ends of the wind shield 14 are connected to the two ends of the first air sweeping plate 11 respectively, the wind shield 14 is arranged on the air outlet end of the fan assembly 122, and a gap exists between the wind shield 14 and the first air sweeping plate 11. The wind shield 14 can guide the airflow to gather in the middle of the air outlet 21, so as to improve the air supply efficiency of the air supply device 1, and can also make the airflow diffuse outward around the air outlet 21, so as to avoid directly blowing the user, and make the airflow more evenly distributed to each corner of the room.

[0056] Specifically, the wind shield 14 is provided with a flow guide hole 141. The flow guide hole 141 is arranged corresponding to the air outlet 21 and the fan blade 1221, so that the fan blade 1221 can convey the airflow to the air outlet 21 through the flow guide hole 141.

[0057] Specifically, the air supply device 1 of the embodiment further comprises two connecting pieces 15, the two connecting pieces 15 are connected to the two ends of the first air sweeping plate 11 in the length direction respectively, and the two ends of the wind shield 14 are connected to the two connecting pieces 15 respectively. The connecting pieces 15 can make the wind shield 14 more firmly connected to the first air sweeping plate 11, and also make a gap exist between the first air sweeping plate 11 and the wind shield 14, so as to provide a rotating space for the second air sweeping plate 121 and the fan assembly 122, ensure that the second air sweeping plate 121 can rotate a larger angle, and further expand the air supply area and range, so as to effectively disperse the airflow, avoid local uneven cold and heat, and improve the use comfort.

[0058] Specifically, the output shaft of the rotating drive piece 13 is connected to one of the connecting pieces 15. The rotating drive piece 13 drives the first air sweeping plate 11 and the wind shield 14 to rotate through the connecting piece 15, the first air sweeping plate 11 takes the output shaft of the rotating drive piece 13 as the rotating center axis of the first air sweeping plate 11, that is, the first air sweeping plate 11 rotates around the output shaft of the rotating drive piece 13. The output shaft of the rotating drive piece 13 is connected to the connecting piece 15, which helps to keep the first air sweeping plate 11 and the wind shield 14 balanced, improves the structural stability of the air supply device 1, and ensures that the first air sweeping plate 11 and the wind shield 14 can keep stable rotation even when the air supply direction is frequently adjusted, reduces the vibration and noise caused by imbalance.

[0059] Specifically, the air supply device 1 of the embodiment further comprises a rotating rod 16, and the rotating rod 16 is connected to the connecting piece 15 away from the output shaft of the rotating drive piece 13. The rotating rod 16 and the output shaft of the rotating drive piece 13 are connected to the two connecting pieces 15 respectively, so that the first air sweeping plate 11 and the wind shield 14 can rotate more stably. In specific implementation, the rotating rod 16 is sleeved with the convex shaft of the inner side wall of the air outlet 21, or is arranged in the concave hole of the inner side wall of the air outlet 21, so as to reduce the friction resistance when the first air sweeping plate 11 rotates, improve the rotation smoothness of the first air sweeping plate 11, and further improve the air supply efficiency and stability of the air supply device 1.

[0060] It can be understood that in other embodiments, the output shaft of the rotating driving member 13 and the rotating rod 16 can be respectively connected to the two ends of the first air sweeping plate 11 or the two ends of the air baffle 14 according to actual needs.

[0061] Specifically, the first air sweeping plate 11 is provided with a first air sweeping part 112 and a second air sweeping part 113, which are arranged along the length direction of the first air sweeping plate 11; the fan assemblies 122 are connected to the first air sweeping part 112 or the second air sweeping part 113, and the number of the fan assemblies 122 on the first air sweeping part 112 and the second air sweeping part 113 is the same. The fan assemblies 122 located on the first air sweeping part 112 swing to the left or to the right, and the fan assemblies 122 on the second air sweeping part 113 swing in the opposite direction to the fan assemblies 122 on the first air sweeping part 112, which can enable the air supply device 1 to simultaneously perform left air sweeping and right air sweeping.

[0062] It can be understood that the air supply device 1 of the embodiment can realize the following air supply modes.

[0063] Mode one: left and right air sweeping, which includes unidirectional air sweeping and bidirectional air sweeping. Unidirectional air sweeping, that is, all the fan blades 1221 simultaneously swing in one direction under the action of the swing driving member 123, such as swinging to the left or to the right, as shown in FIG. 6, which is suitable for scenes requiring concentrated air supply; bidirectional air sweeping, that is, the fan blades 1221 on the first air sweeping part 112 and the second air sweeping part 113 swing in opposite directions to achieve more extensive air flow coverage, as shown in FIG. 7, which is suitable for scenes requiring large-area air supply. Figure 3 Figure 4 Mode two: up and down air sweeping. The second air sweeping plate 121 is parallel to the first air sweeping plate 11, the swing driving member 123 is not working, and the rotating driving member 13 drives the first air sweeping plate 11 to swing up and down. The up and down air sweeping mode of the fan blades 1221 in this mode is similar to the working mode of the traditional air deflector, but the air supply device 1 of the embodiment improves the air output and further improves the air supply efficiency and enhances the comfort of the user in combination with the arrangement of the fan assemblies 122.

[0064] Mode three: comprehensive air sweeping. The fan blades 1221 can perform comprehensive up and down and left and right air sweeping under the action of the rotating driving member 13 and the swing driving member 123, which realizes multi-dimensional air flow control and ensures the uniformity of air flow distribution and the extensiveness of coverage, further improving the air supply effect.

[0065] Mode three: comprehensive air sweeping. The fan blades 1221 can perform comprehensive up and down and left and right air sweeping under the action of the rotating driving member 13 and the swing driving member 123, which realizes multi-dimensional air flow control and ensures the uniformity of air flow distribution and the extensiveness of coverage, further improving the air supply effect.

[0066] ​Mode four: custom wind direction adjustment. Users can customize the rotation speed and swing angle of the fan blades 1221 according to actual needs to adjust the wind direction of the air supply device 1 in any one direction or all directions in the four directions of up, down, left and right, thereby realizing diversified needs such as soft wind, strong wind, and fixed-point air supply. This highly personalized setting provides users with more accurate and comfortable air supply experience.

[0067] More specifically, the amplitude range of left-right sweeping wind of the air supply device 1 of the embodiment is (-60°, 30°), wherein the angle of sweeping wind to the left and right sides is negative, and the angle of sweeping wind to the middle part is positive. The mutual interference between the fan blades 1221 is effectively avoided, ensuring the maximization of the sweeping wind area, thereby improving the air supply efficiency and comfort.

[0068] More specifically, the amplitude range of up-down sweeping wind of the air supply device 1 of the embodiment is (-75°, 60°), wherein the angle of sweeping wind upward is positive, and the angle of sweeping wind downward is negative. It is worth mentioning that the up-down sweeping wind angle cannot reach -90° to avoid the wind directly blowing into the air conditioner 2 to cause equipment damage or performance degradation, not only ensuring the uniformity and comfort of the air supply of the air supply device 1, but also effectively protecting the normal operation of the air conditioner 2 equipment.

[0069] Embodiment two

[0070] Referring to Figures 1-9 As shown in the figure, the embodiment discloses an air conditioner 2 comprising the air supply device 1 of embodiment one. The air conditioner 2 of the embodiment is provided with an air outlet 21, and the air supply device 1 is arranged at the air outlet 21.

[0071] The air conditioner 2 of the embodiment is equipped with the air supply device 1 with large sweeping wind range, uniform dispersion, and high personalization, so that the air conditioner 2 can provide a more comfortable use environment for users. The multi-dimensional air flow control function of the air supply device 1 allows the air conditioner 2 to adjust the air supply direction and intensity according to the user's needs. The fan assembly 122 can be driven by the first sweeping plate 11 and the second sweeping plate 121 to realize adjustment of different angles and directions, making the air flow distribution more uniform and avoiding the problem of local cold and hot unevenness, thereby improving the overall heat exchange efficiency and cooling effect of the air conditioner 2, reducing additional energy consumption, and achieving energy saving and environmental protection. Not only helps to reduce the user's electricity bill, but also meets the pursuit of green, environmental protection and sustainable development in modern society.

[0072] In specific implementation, users can easily adjust the working mode and parameters of the air supply device 1, such as setting the air supply angle, wind speed, air supply mode, etc. through the remote controller of the air conditioner 2, mobile phone APP or smart home system.
