Preferably, the initial position is a central position of the guide rail 13 a.
In practice, as mentioned above, all the vane assemblies 20 need only be moved to the same vertical plane, and there is no limitation on the specific moving position, for example, all the vane assemblies 20 can be moved to the position where the most vane assemblies 20 are currently located.
For example, a window blind has 20 blade devices 20, and the moving positions of the blade devices 20 include three positions, namely, the central position of the guide rail 13a and the two end positions of the guide rail 13 a. If it rains, 10 blade devices 20 are located at one end of the guide rail 13a close to the outdoor, 5 blade devices 20 are located at one end of the guide rail 13a close to the indoor, and 5 blade devices 20 are located at the center of the guide rail 13a, then the following 10 blade devices 20 can be moved to one end of the guide rail 13a close to the outdoor, so that the 20 blade devices 20 are located in the same vertical plane, and the movement amount required by the method is minimum.
It should be understood that the moving position of the vane device 20 is not limited to the aforementioned three, and the entire stroke section of the guide rail 13a may be the moving position of the vane device 20.
Thirdly, automatically adjusting lighting and ventilation
The sliding window comprises a light intensity sensor 41 and a particulate matter concentration sensor 43.
The light intensity sensor 41 is arranged on the side, facing outdoors, of the frame 11 and is connected with the processor 50, the light intensity sensor 41 is used for detecting outdoor light intensity, and if the outdoor light intensity is larger than a preset light intensity threshold value, a first level signal is generated and sent to the processor 50.
The particulate matter concentration sensor 43 is arranged on one side of the frame 11 facing the indoor space and connected with the processor 50, the particulate matter concentration sensor 43 is used for detecting the concentration of the indoor particulate matter, and if the concentration of the indoor particulate matter is larger than a preset concentration threshold value, a second level signal is generated and sent to the processor 50.
The processor 50, in response to receiving only the first level signal, sends a switching control command to the light valve switching unit 60 to switch some or all of the paddle means 20 to the frosted state.
The processor 50 sends a switching control instruction to the light valve switching unit 60 to switch some or all of the blade devices 20 to the frosted state in response to receiving the first level signal and the second level signal at the same time, and sends a first push-pull control instruction to some of the push-pull mechanisms 13 to move some of the blade devices 20 to the outdoor or indoor, or sends a first push-pull control instruction and a second push-pull control instruction to some or all of the push-pull mechanisms 13 to move some or all of the blade devices 20 to the outdoor or indoor, respectively, where the moving directions of the first push-pull control instruction and the second push-pull control instruction are opposite.
The particulate matter concentration sensor 43 is used for detecting the indoor particulate matter concentration, including PM2.5 concentration and the like, for example, when someone smokes, the indoor particulate matter concentration can rise rapidly, and indoor personnel need to open windows for ventilation and the like. As mentioned above, the ventilation function can be achieved by turning the blade arrangement 20 or pushing or pulling the blade arrangement 20. If the outdoor light is strong, the blade device 20 can be pushed or pulled and the blade device 20 can be switched to the frosted state at the same time, so that the compatible effects of ventilation and lighting can be realized.
As can be seen from the foregoing, the farther the distance between adjacent vane devices 20 is, the larger the generated ventilation channel is, and the sliding window can determine the width of the generated channel, that is, the push-pull mode of the vane device 20 according to the specific value range of the indoor particulate matter concentration.
For example, when the concentration of particulate matter in the room is very high, the adjacent vane devices 20 are pushed in opposite directions to both ends of the guide rail 13a, respectively, to generate the maximum ventilation passage. When the indoor particulate matter concentration is high, part of the vane device 20 is pushed outward or inward, a smaller ventilation passage is created, and the like.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. The present invention is intended to cover by those skilled in the art various modifications and adaptations of the invention without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is subject to the claims.
