Detailed ways

In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and functions of the elevator car air guide device proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Its efficacy is described in detail as follows.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of setting an elevator car air vent according to an embodiment of the present invention. Ventilation opening 12 is arranged on the position in elevator car 10 not limited, can be arranged on the upper, middle, lower part of car wall plate 11 or on car enclosure, skirting board 13 according to actual needs. The shape of the air vent 12 is not limited, and its size is in accordance with the national standard. In this embodiment, it is designed as a square, and it can also be designed as other geometric shapes such as arc, circle or polygon according to the aesthetic requirements. The number of vents 12 in the elevator car 10 can be designed as one or more according to actual needs. In addition, the 12 vents can also be properly decorated, such as installing ventilation nets. In the case of a suspended ceiling or a car enclosure, the air vent 12 can be arranged within its shielding range to improve the aesthetics of the car.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of installation of an elevator car air guide device according to an embodiment of the present invention. There are two ways to install the air guiding device 20: one is to be hinged and fixed. As in this embodiment, the air guiding device 20 is hinged and fixed to the middle position of the external air vent 12 of the elevator car through the support mechanism 22. The natural wind driven by the lower operating condition makes the wind deflector 21 swing naturally. Another way is to fix directly, by directly fixing one side of the air deflector 21 to the air vent 12 of the car wall plate 11 to conduct air guidance, before fixing, the air guide direction of the air deflector 21 needs to be adjusted (the air deflector 21 Be fixed dead, can not swing). Regardless of the installation method, it is necessary to ensure that the air guide device is installed firmly, and the natural wind gathered outside the elevator car 10 can smoothly pass through the V-shaped guide plate 21 of the air guide device 20 and the car wall 11. The air passages 121 and 122 enter the interior of the elevator car 10, thereby increasing the gas convection velocity and flow rate in the car, and achieving the purpose of improving the ventilation effect in the car.

Please refer to FIG. 3 . FIG. 3 is a schematic structural diagram of an elevator car air guide device according to an embodiment of the present invention. The air guide device 20 is composed of an air guide plate 21 and a support mechanism 22 connected to the air guide plate 21 . In this embodiment, the support mechanism 22 can be designed as a support rod or a support frame that functions as a rotating shaft according to actual conditions. The wind deflector can be bent from profiles, and its bending angle can be between 100° and 180°, preferably 120°. The wind deflector 21 and the support mechanism 22 can be welded or pin-hole positioning. To be connected together, it is necessary to ensure that the connection is tight and firm; the two plates can also be welded or positioned on a support rod or a support frame by pin holes, and the two plates form an angle of 100° to 180°.

In addition, please refer to FIG. 4 again. FIG. 4 is a schematic plan view of an elevator car air guide device according to an embodiment of the present invention installed outside the car. As shown in the figure, a plurality of ventilation openings 12 are provided on the wall panel 11, the enclosure, the bottom frame of the elevator car or the skirting board 13 of the elevator car 10, and a plurality of air guiding devices 20 are added at the plurality of ventilation openings 12. When the elevator runs up and down, the air guide plates 21 of the plurality of air guide devices 20 swing up and down to guide the natural wind in the hoistway to enter the elevator car 10 . At the same time, setting the cross-flow fan 40 on the car roof of the elevator car 10 can also increase the gas convection velocity and flow rate in the elevator car 10, and achieve the purpose of improving the ventilation effect in the elevator car 10 to a greater extent. In addition, decorations can also be added on the air vents 12 in the elevator car 10 to enhance the aesthetics of the elevator car. A protective net (not shown) can be set outside the air guiding device 20 to enhance the safety of the elevator car operation. The air deflector 21 of the air deflector 20 can also be installed on the surface opposite to the wall plate 11, which is similar to a rubber vibration damping and noise reduction device 30, which can reduce the noise generated when the air deflector 20 swings back and forth, and improve the performance of the elevator when taking the elevator. comfort.

The specific operating conditions of the elevator with the air guiding device installed in the elevator car are further described below:

When the elevator goes up, the air deflector 21 of the air deflector 20 of the embodiment of the present invention swings downward under the action of wind pressure, the lower bending surface of the air deflector is in contact with the elevator wall 11, and the upper bending surface is in contact with the elevator wall. The plate 11 forms a V-shaped air guide channel 121, which forms a positive pressure at the car vent 12, guides the natural wind outside the elevator car 10 to blow into the car quickly and in large quantities, and then utilizes the through-flow installed on the car roof. The fan 40 exhausts the air so that the air in the elevator car 10 forms an effective circulation, thereby improving the feeling of stuffiness in the car 10 .

When the elevator goes down, the wind guide plate 21 of the air guide device 20 in the embodiment of the present invention swings upward under the action of wind pressure, the bent surface on the wind guide plate is in contact with the elevator wall plate 11, and the lower bent surface is in contact with the elevator wall plate 11 forms a V-shaped air guide channel 122, forming a positive pressure at the car vent 12, guiding the natural wind outside the elevator car 10 to blow into the car, and then utilizing the cross-flow fan 40 arranged on the car top to exhaust the air, so that The ventilation speed in the elevator car 10 is accelerated, so as to achieve the purpose of strengthening the air flow in the elevator car 10 .

The above detailed description is a specific description of one of the feasible embodiments of the present invention. This embodiment is not intended to limit the patent scope of the present invention.
