Embodiment 1

[0027] In this embodiment, a low-noise ventilation guide system in the car, such as figure 1 As shown, a soundproof box 1, an air duct 2, a muffler 3 and an air guiding device 4 are included.

[0028] Such as figure 1 , Figure 5 with Image 6 As shown, the soundproof box is installed outside the elevator car. The soundproof box is a square box body composed of an upper cover plate 9, a lower cover plate 11 and four surrounding panels 10. A mesh hole 9 is arranged on the upper cover plate. Ventilation openings 13 are arranged on the cover plate. The blower fan 8 is arranged in the soundproof box, specifically is installed on the lower cover plate, and the air outlet of the blower fan is aligned with the air vent. In order to further improve the sound insulation effect, such as figure 1 with Figure 4 As shown, a layer of sound-absorbing cotton 14 is respectively arranged on the enclosure and the lower cover, and a layer of rubber layer 15 is also arranged between the sou...

Embodiment 2

[0034] This embodiment provides the structure of another low-noise ventilation guide system in the car, such as image 3As shown, the difference is the air guide device, which is installed on the side wall of the car. The air guide device includes an air guide port, and a piece of louver 6 is arranged in the air guide port. At one side of the air guide port, the rotating shaft is connected to a motor, and the motor is connected to the control unit, and the control unit controls the louvers to rotate 90 degrees. In this way, the wind blown by the fan can be evenly distributed in the car. Other structures are the same as those described in Example 1.

Abstract

The invention relates to a low-noise elevator car internal ventilation and air deflecting system and solves the problems that a conventional elevator car internal ventilation device has the disadvantages of high blower noise and invariable air volume. The system comprises a blower, an air duct and a control unit for controlling the operation of the blower; one end of the air duct is connected to the air outlet of the blower, and the other end of the air duct is connected with the elevator car; the blower is installed in a soundproof box, a ventilation opening is formed on the soundproof box, and the air outlet of the blower is connected with the air duct through the ventilation opening; a silencer is arranged on the air duct; and an air deflecting device is arranged at a port of the air duct, where the air duct is connected with the elevator car. The system has the advantages that the noise is effectively reduced on the basis of maintaining big air volume; the ventilation in the elevator car is more uniform, and the comfort of passengers taking an elevator is improved; and the air volume of the blower can be adjusted according to temperature and passenger capacity, so as to further meet the requirements of the passengers and to be more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to an elevator device, in particular to a low-noise and evenly ventilated car interior ventilation and air guide system. Background technique [0002] The fan used in the elevator car is generally exposed to the rear or both sides of the car. Its main function is to ventilate the car, and the fan rotates at high speed to generate noise. Since the car is a closed reverberation field, the noise of the fan is amplified in the car, which seriously affects the comfort of passengers. [0003] In addition, the ventilation in the car is unevenly distributed, only the sides or the middle can blow the wind, and it is impossible to achieve uniform ventilation in all parts of the car. The fan rotates at a constant speed, and the air volume does not change. With the same air volume, passengers feel that the air volume is too large in winter and too small in summer, which cannot meet customer needs. [0004] For example, the Chinese utility m...
