Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1, the elevator of the present invention comprises a car 1, wherein an air circulation mechanism is installed on the car 1, and an air circulation space is formed in an inner cavity of the car 1 to circulate air.
The air circulation mechanism comprises a shell, a circulating fan driven by a motor and rotating is arranged in the shell, the shell is provided with an air inlet 3 and an air outlet 2 through pipelines, and the air inlet 3 and the air outlet 2 are communicated with an air circulation space. The air circulation mechanism enters air from the air inlet 3 and exhausts air from the air outlet 2 by the rotation of the circulation fan.
Referring to fig. 2, the inner wall of the air outlet 2 is provided with guide vanes 4 circumferentially arrayed along the axis, the outer side surfaces of the guide vanes 4 are fixedly connected with the inner wall of the air outlet 2, and the inner side surfaces of the guide vanes 4 are adjacent to the axis of the air outlet 2; the guide vanes 4 extend obliquely downwards along a spiral line, and guide channels 41 communicated with the air outlet 2 are formed between adjacent guide vanes 4, so that air flow enters the air outlet 2 along the axial direction and is spirally wound around the air outlet 2 from each guide channel 41 respectively.
In order to ensure the flow guiding effect of the flow guiding blades 4, the cross sections of the flow guiding blades 4 are arc-shaped, so that the continuity of the flow guiding channel 41 is ensured, and the wind direction is convenient to change; the lower end of each guide vane 4 is located at the lower side of the adjacent guide vane 4, thereby controlling the width of the guide passage 41 and ensuring that the guide passage 41 can change the flow direction of the air flow.
The air outlet 2 and the air inlet 3 are arranged at the top of the air circulation space, and an interlayer can be arranged on the side wall of the air circulation space to lay a channel, so that the air outlet 2 and the air inlet 3 are arranged on the side surface of the air circulation space; and the air outlet 2 and the air inlet 3 can be arranged on the same side surface, and also can be oppositely arranged on two side surfaces of the two cages 1.
The air inlet 3 is sleeved on the inner side of the air outlet 2, and the air inlet 3 and the air outlet 2 are coaxially arranged. As shown in fig. 3, the air inlet 3 forms positive pressure, the air outlet 2 forms negative pressure, so that the air flow spirally enters the car 1 from the periphery, then spreads and rises towards the outer periphery, and finally gathers together with the air outlet 2 to form an ordered air circulation path. Compared with the common straight-in straight-out air circulating device, the range of the internal purification space of the elevator car is doubled by installing the air guide device, and the purification removal rate of pollutants in the air is obviously improved by 10 percent.
