Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0028] like Figure 1 and Figure 2 As shown, on the one hand, an embodiment of the present application provides a wind guide structure 101, which includes a wind guide plate 10 and a driving device 20, which can reduce the cost of the driving device of the wind guide plate 10 and improve the swing stability of the wind guide plate 10.

[0029] The driving device 20 is disposed in the middle area of ​​the air guide plate 10, and the driving device 20 is configured to drive the air guide plate 10 to rotate. Here, the middle area may refer to an area near the center of the air guide plate 10, for example, an area near the center of the air guide plate 10 along its length direction / width direction. When the air guide structure 101 is disposed at the air outlet 1021 of the air conditioner indoor unit 100, the air guide plate 10 may swing to guide air under the drive of the driving device 20.

[0030] Compared with the related art, the air guide structure 101 provided in the embodiment of the present application only has a driving device 20 arranged in the middle area of ​​the air guide plate 10. On the one hand, there is no need to respectively arrange driving devices at both ends of the air guide plate 10, which can effectively reduce the number and cost of driving devices required. On the other hand, the problem of driving asynchrony existing in multiple driving devices can be avoided based on a single driving device 20, and the driving device 20 is centrally arranged or close to being centrally arranged, which can improve the swing stability of the air guide plate 10.

[0031] The composition structure of the driving device 20 can be determined according to actual needs, and the embodiment of the present application does not limit this. Figure 3As shown, in some embodiments, the driving device 20 may include a driving motor 21 and a reduction mechanism 22; the type of the driving motor 21 may be determined according to actual needs, and may be, for example, a stepping motor, a servo motor, etc., which is not limited in the embodiments of the present application. The air deflector 10 may include a transmission connection portion 11, which is disposed in the middle area of ​​the air deflector 10; the reduction mechanism 22 connects the driving motor 21 and the transmission connection portion 11 to adjust the output speed and output torque of the driving motor 21 to the swing speed and swing torque required by the air deflector 10. In this way, the reduction mechanism 22 can transmit the motion output by the driving motor 21 to the transmission connection portion 11, thereby driving the air deflector 10 to swing and guide the air.

[0032] The structure of the speed reduction mechanism 22 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some examples, the speed reduction mechanism 22 may include a driving gear 221 and a gear shaft 222 that mesh with each other. The driving gear 221 is fixed to the output shaft of the driving motor 21 and rotates together with the output shaft of the driving motor 21; the gear shaft 222 has a gear portion and a shaft end, and the gear portion and the driving gear 221 mesh. A connecting hole 111 is provided on the transmission connection part 11, and the shaft end of the gear shaft 222 and the connecting hole 111 are sleeved and fixed so that the gear shaft 222 and the transmission connection part 11 rotate synchronously. In this way, the driving motor 21 drives the driving gear 221 to rotate, and the driving gear 221 drives the gear shaft 222 to rotate synchronously, and then the wind deflector 10 is driven to swing and guide the wind through the cooperation of the shaft end of the gear shaft 222 and the connecting hole 111.

[0033] Exemplarily, the speed reduction mechanism 22 may further include a first housing 223 and a second housing 224. The first housing 223 and the second housing 224 are connected to enclose a mounting cavity, and the driving gear 221 and the gear shaft 222 may be respectively disposed in the mounting cavity, and the driving gear 221 and the gear shaft 222 are protected by the first housing 223 and the second housing 224. The driving motor 21 is disposed on the first housing 223, and the output shaft of the driving motor 21 passes through the first housing 223 and is connected and fixed to the driving gear 221, while the shaft end of the gear shaft 222 passes through the second housing 224 and extends outside the mounting cavity to be sleeved and fixed to the connecting hole 111 on the transmission connecting part 11.

[0034] The transmission ratio of the driving gear 221 and the gear shaft 222 can be determined according to actual needs, so that the output torque of the gear shaft 222 is sufficient to drive the air deflector 10 to swing at a preset speed, and the embodiment of the present application does not limit this. Exemplarily, the transmission ratio of the driving gear 221 and the gear shaft 222 can be set to be greater than or equal to 2:1, and the transmission ratio of the driving gear 221 and the gear shaft 222 is inversely proportional to the gear ratio of the two, that is, the transmission ratio is equal to the number of teeth of the gear shaft 222 divided by the number of teeth of the driving gear 221. Within this transmission ratio range, the output torque of the gear shaft 222 can relatively stably drive the air deflector 10 to swing at a preset speed. The shape of the shaft end of the gear shaft 222 and the connecting hole 111 can be determined according to actual needs, and can adopt, for example, a square hole shape or other special-shaped hole shapes, and the embodiment of the present application does not limit this. Exemplarily, the shaft end of the gear shaft 222 may be an outer hexagonal shaft end, and the connecting hole 111 may be an inner hexagonal hole, so that the shaft end of the gear shaft 222 and the connecting hole 111 can be connected and fixed more reliably.

[0035] like Figure 1 and Figure 5 As shown, in some examples, the distance L between the midpoint of the air deflector 10 along the first direction and the side of the transmission connection part 11 connected to the speed reduction mechanism 22 can be set to be less than or equal to one tenth of the length of the air deflector 10. Here, the first direction can be the length direction of the air deflector 10. When the speed reduction mechanism 22 includes a driving gear 221 and a gear shaft 222 that mesh with each other, the side of the transmission connection part 11 connected to the speed reduction mechanism 22 is the side of the transmission connection part 11 connected to the gear shaft 222, which is also equivalent to the end face of the gear shaft 222 that contacts the transmission connection part 11; accordingly, the distance between the end face of the gear shaft 222 that contacts the transmission connection part 11 and the midpoint of the air deflector 10 along the first direction can be set to be less than or equal to one tenth of the length of the air deflector 10. By limiting the connection positions of the transmission connection part 11 and the speed reduction mechanism 22 as above, after the drive device 20 and the air guide plate 10 are installed, the drive device 20 can be closer to the midpoint of the air guide plate 10 along the first direction, and thus can better overcome the influence of the deadweight of the air guide plate 10; in this way, after the air-conditioning indoor unit 100 is shut down, the air guide plate 10 can be closed more tightly at the air outlet 1021 of the air-conditioning indoor unit 100, avoiding the problem that the air guide plate 10 is not closed tightly and there is an obvious gap.

[0036] For example, the distance between the end of the driving device 20 away from the transmission connection part 11 and the midpoint of the air guide plate 10 along the first direction can be set to be less than or equal to one tenth of the length of the air guide plate 10. By defining the setting position of the driving device 20 on the air guide plate 10 as above, the driving device 20 can be further made closer to the midpoint of the air guide plate 10 along the first direction, and the influence of the deadweight of the air guide plate 10 can be better overcome; after the air conditioner indoor unit 100 is shut down, the air guide plate 10 can be more tightly closed at the air outlet 1021 of the air conditioner indoor unit 100, thereby improving the tightness of the air guide plate 10 when it is closed.

[0037] like Figure 4 As shown, in some examples, the air guide plate 10 may include two rotating connection parts 12. The two rotating connection parts 12 are respectively arranged on opposite sides of the transmission connection part 11 along the first direction, and each rotating connection part 12 is respectively configured to be rotatably connected to the indoor unit housing 102, so that the air guide plate 10 can be rotatably maintained at the air outlet 1021 of the air conditioner indoor unit 100. After the driving device 20 and the indoor unit housing 102 are installed and fixed, the air guide plate 10 is indirectly rotatably connected to the indoor unit housing 102 through the transmission connection part 11 and the driving device 20; in this way, the air guide plate 10 and the indoor unit housing 102 can be rotatably connected respectively through the transmission connection part 11 and the two rotating connection parts 12, and the two form a three-shaft connection structure; the three-shaft connection structure can obtain a higher coaxiality, so that the air guide plate 10 is more evenly stressed and has higher swing stability. Exemplarily, the rotatable connection portion 12 may be provided with a pin shaft, and the side walls on opposite sides of the air outlet 1021 may be provided with matching holes respectively, and the pin shaft can be rotatably retained in the matching holes.

[0038] like Figures 1 to 5 As shown, on the other hand, an embodiment of the present application provides an air-conditioning indoor unit 100, which includes an indoor unit housing 102 and an air guide structure 101 provided in any of the above embodiments. An air outlet 1021 is provided on the indoor unit housing 102, and the air guide plate 10 is rotatably arranged at the air outlet 1021. Here, the driving device 20 can be fixed on the indoor unit housing 102, and the air guide plate 10 and the indoor unit housing 102 are rotatably connected. The type of the air-conditioning indoor unit 100 can be determined according to actual needs, and the indoor unit structure type of a split air conditioner such as a wall-mounted air conditioner, a cabinet air conditioner, etc. can be adopted, and the embodiment of the present application does not limit this. The air-conditioning indoor unit 100 provided in the embodiment of the present application has the above-mentioned air guide structure 101, so that the cost of the driving device of the air guide plate 10 can be reduced and the swing stability of the air guide plate 10 can be improved.

[0039] In some embodiments, a mounting groove 1022 may be provided on the inner surface of the indoor unit housing 102, and the driving device 20 is embedded in the mounting groove 1022. In this way, the driving device 20 can be installed in the mounting groove 1022 in a hidden manner, can be well protected by the indoor unit housing 102, and can improve the aesthetics of the air conditioner indoor unit 100. In some examples, the mounting groove 1022 can be provided in an area near the air outlet 1021 on the inner surface of the indoor unit housing 102.

[0040] The air guide structure and the air-conditioning indoor unit provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scope.
