Although certain features may be combined together to illustrate a possible system design, such features may be used in other combinations not explicitly described. Thus, unless otherwise indicated, the illustrated combinations are not intended to be limiting.
The principles of the present utility model are described in detail below with reference to the drawings and examples.
As shown in fig. 1-8, the utility model provides a turnover type air duct air outlet, which comprises a fan-shaped air door 100, a connecting frame 200 and a driving mechanism, wherein the connecting frame 200 is arranged at the tail end 300 of an air duct, the fan-shaped air door 100 is rotatably arranged at the inner side of the connecting frame 200, and the driving mechanism is used for driving the fan-shaped air door 100 to rotate;
The fan-shaped air door 100 is provided with a fan-shaped tube cavity 1, one end of the fan-shaped tube cavity 1 is provided with an air inlet 11, the other end is provided with an air outlet 12, and a plurality of rotating grid bars 14 are arranged on an outer side sector 13 of the fan-shaped air door 100;
When the air outlet 12 is turned over and received in the connection frame 200, the turnstile 14 is opened by falling down by gravity;
when the air outlet 12 is turned over and extends out of the connecting frame 200, the turning bars 14 are closed by gravity engagement.
The fan-shaped air door 100 can be turned over to switch between the lower air outlet state and the side air outlet state, and as the fan-shaped air door 100 is turned over, the rotating grills 14 can open or close the outer fan surface 13 by gravity so as to form an air duct of lower air outlet or side air outlet.
According to the indoor decoration, the air duct end 300 of the air conditioning system may be vertically downward, and at this time, the turnover air duct outlet is installed at the horizontal ceiling of the roof; the duct end 300 may also extend horizontally, where the roll-over duct outlet is mounted to the side of the suspended ceiling. Taking the example that the air duct end 300 is vertically downward, the working principle of the turnover air duct air outlet is as follows:
The initial state of the air outlet of the turnover type air pipe is a lower air outlet state, at the moment, the fan-shaped air door 100 is completely retracted into the connecting frame 200 and the air pipe, in order to avoid the air channel blockage caused by the rotating grid 14, the rotating grid 14 rotates and falls down to be in a vertical state under the action of gravity, and cold air flows downwards through the fan-shaped air door 100;
When the fan-shaped air door 100 needs to be changed into a side air outlet state, the fan-shaped air door 100 is turned over under the action of the driving mechanism and gradually stretches out of the connecting frame 200 until the air outlet 12 is in a vertical state, at the moment, the rotating grid bars 14 rotate under the action of gravity, and the outer side fan surfaces 13 of the fan-shaped air door 100 are blocked one by one in a joint mode, so that the fan-shaped air door 100 forms a corner air channel, and the side air outlet effect is achieved.
The fan-shaped air door 100 is a pentahedron, the air outlet 12 and the air inlet 11 are respectively positioned on two perpendicular surfaces, the other two side plates 15 are respectively positioned on two parallel surfaces, and the remaining surface is the outer fan surface 13. The two side plates 15 are provided with a plurality of pairs of stub shafts 16, and each turnstile is rotatably mounted on a pair of stub shafts 16. The turning bars 14 are asymmetrically arranged relative to the short shaft 16, that is, the area of the turning bars 14 on one side of the short shaft 16 is larger, and the area of the other side is smaller, so that the gravity center of the turning bars 14 is continuously changed when the fan-shaped air door 100 rotates, and the turning bars automatically turn under the action of gravity. In order to avoid air leakage of the outer sector 13 of the fan-shaped air door 100 in the side air outlet state, the rotating side of the rotating grid 14, which is close to the rotating shaft, is provided with a first magnetic attraction strip 141, the rotating side of the other side of the rotating grid 14, which is far away, is provided with a second magnetic attraction strip 142 which is weighted, and when the rotating sides are connected piece by piece, the first magnetic attraction strip 141 of one rotating grid 14 attracts the second magnetic attraction strip 142 of the adjacent rotating grid 14, so that all the rotating grid 14 are connected into a whole, and gaps are avoided from being generated between the rotating grid 14.
Unlike the background art, the air outlet in the background art is an integral plastic piece, but the embodiment is divided into two main parts of the fan-shaped air door 100 and the connecting frame 200, the connecting frame 200 is used for connecting and fixing, and the fan-shaped air door 100 is used for changing the wind direction.
The driving mechanism comprises a first rack 21, a driving motor 22, a driving belt 23 and a transmission shaft 24, wherein the first rack 21 is arranged on the outer side of the outer sector 13, the driving motor is fixed on the connecting frame 200, one end of the transmission shaft 24 is provided with a gear which is meshed with the first rack 21, and the other end of the transmission shaft is in transmission connection with a rotating shaft of the driving motor 22 through the driving belt 23. The driving motor 22 can drive the fan-shaped air door 100 to turn up and down through the driving belt 23 and the driving shaft 24, so that the switching between the lower air outlet state and the side air outlet state is realized.
In this embodiment, the turnover air duct air outlet is further provided with a braking mechanism, and the braking mechanism includes a second rack 31, a friction block 32, a spring 33 and an electromagnetic switch 34. The second rack 31 is arranged outside the outer sector 13 in parallel with the first rack 21, the electromagnetic switch 34 is fixed on the connecting frame 200 and is provided with an opening, the friction block 32 is opposite to the second rack 31, the back surface of the friction block is provided with a tail rod 35, the rear end of the tail rod 35 is telescopically arranged in the opening, and the spring 33 is positioned in the opening and is arranged at the rear end of the tail rod 35.
The braking device is used to limit the overturning of the fan damper 100. The electromagnetic switch 34 and the driving motor 22 work synchronously, when the driving motor 22 works, the electromagnetic switch 34 is electrified synchronously, the tail rod 35 made of iron material is retracted backwards under the action of magnetic force against the elastic force of the spring 33, and the friction block 32 is separated from the second rack 31 so as not to prevent the fan-shaped air door 100 from overturning; when the driving motor 22 is powered off, the electromagnetic switch 34 is synchronously powered off, and the friction block 32 is pushed forward to be in close contact with the second rack 31 under the action of the spring 33, so that the fan-shaped air door 100 is limited to overturn by friction force.
The second rack 31 is composed of a plurality of transverse teeth, and the friction surface of the friction block 32 is split into a plurality of transversely extending friction strips 321, so that the friction force between the friction block and the second rack 31 can be increased.
In this embodiment, one side of the connection frame 200, which is close to the air duct, is provided with an air duct slot 41, and the opposite side is provided with a seat board 42, and the electromagnetic switch 34 and the driving motor are mounted on the seat board 42. The air pipe slot 41 is used for inserting an air pipe for butt joint, and the seat board 42 is used for fixing the suspended ceiling. The turnover air duct air outlet further comprises a veneer 43, wherein the veneer 43 is used for clamping the suspended ceiling by being matched with the seat board 42, and the turnover air duct air outlet further has a beautifying effect. The veneer 43 and the seat plate 42 are provided with fixing holes, and can be fixed by bolts.
