Summary of the invention
The problem that invention will solve
; according to the scheme disclosed in above-mentioned patent documentation 1; although the noise propagated in lift car can be reduced; but because needs form shell shape between lift car and car frame; and need to form silence space; so airspace cannot be arranged in lift car, exist cannot meet the regulation such as external specification lift car in the problem of air-conditioning requirement.
The present invention makes on the basis considering the problems referred to above point, the object of the present invention is to provide a kind of airspace can be set in lift car while reduce lift facility and the noise reducing method of noise in lift car.
For solving the technical scheme of problem
In order to solve the problem, lift facility provided by the present invention is provided with airspace, the feature of described lift facility is, there is microphone, loud speaker and control setup, described microphone is for detecting the noise in lift car, described loud speaker produces sound equipment, and described control setup makes described microphone detect to enter from the hoist trunk of described lift facility the noise in lift car, and makes described loud speaker produce the phase place sound equipment contrary with the noise that described microphone detects.
According to said structure, the noise entered from airspace in the lift car of lift facility can be detected, and the phase place sound equipment contrary with the noise detected can be produced in lift car.Thereby, it is possible to arrange airspace in lift car, and the noise in lift car can be reduced.
Invention effect
According to the present invention, airspace can not only be set in lift car, and the noise in lift car can be reduced.

Detailed description of the invention
Referring to accompanying drawing, one embodiment of the present invention is described in detail.
First be described with reference to the lift facility of Fig. 1 to present embodiment.As shown in Figure 1, be respectively arranged with airspace in the upper and lower of the lift car 2 of lift facility, in airspace, be provided with loud speaker 7 and microphone 4.
Microphone 4 detects the noise 3 entered from the hoist trunk of lift facility in lift car 2 under the control of control setup 5 described later.On the other hand, loud speaker 7 produces the phase place sound equipment contrary with the noise that microphone 4 detects under the control of control setup 5.
Control setup 5 and instrument box (BOX) 6 is provided with at the top 10 of lift car 2.Control setup 5 has the sound that microphone 4 detects is converted to the contrary signal of phase place, and produces the function of the corresponding sound equipment of the signal contrary with the phase place converted from loud speaker 7.Microphone 4 is connected with control setup 5 by cable with loud speaker 7.
The instrument box (BOX) 6 of control setup 5 from the lift car being arranged on lift facility obtains power supply, continue to detect the noise 3 entered from airspace in the lift car 2 of lift facility, and continue through loud speaker 7 in lift car 2, produce the contrary sound equipment of phase place.
In addition, as shown in Figure 3, at the airspace of lift car 2, the multiple positions between the top 10 and the side side plate 8 of cage side plate portion on lift car 2 top are provided with ventilation distance piece (distance piece) 11.In addition, the multiple positions between the top 10 and the back side side plate 9 of car back portion on lift car 2 top are provided with ventilation distance piece 11.
In addition, as shown in Figure 4, in the bottom of lift car 2, the multiple positions between the skirting board portion 13 and the side side plate 8 of car side plate of car floor are provided with ventilation distance piece 11.Further, the multiple positions between the skirting board 13 and the back side side plate 9 of car back portion of car floor are provided with ventilation distance piece 11.
Cover body 12 is being set on the side plate of hoist trunk, while guaranteeing necessary airspace, the access passage of noise 3 is being arranged to labyrinth structure.According to this structure, the approach axis of noise 3 can be limited, and noise can be detected conveniently by microphone 4.
The noise produced due to the front side in lift car 2, center side and rear side is different from each other, so also can multiple positions below the car of the side of lift car 2, lift car 2 side car above multiple positions, the back side car below multiple position and the back side car above multiple positions microphone and loud speaker are set, to detect noise respectively, and produce the contrary sound equipment of phase place.
Such as, can be as shown in Figure 5, multiple microphone and loud speaker are set respectively in the side of lift car 2 top (cross section DD) and the back side, and also multiple microphone and loud speaker can be set respectively in the side of lift car 2 bottom (cross section EE) and the back side.Thus, noise reducing effect can be obtained in all positions in lift car 2.
In addition, multiple microphone and loud speaker can be set on the top of lift car 2 or bottom or top and bottom, and also can change the magnitude setting of microphone and loud speaker according to the size of lift facility.Such as, when the depth size of lift facility is large or top height time, the magnitude setting of microphone and loud speaker can be increased further.In addition, also can change magnitude setting, the setting position of microphone and loud speaker according to the shape of lift car or interval etc. is set.
In the present embodiment, continue through microphone and detect noise, and produce the phase place sound equipment contrary with the noise detected by loud speaker, but also can be arranged to make microphone detect noise according to prespecified command speed, and produce the contrary sound equipment of phase place by loud speaker.
In addition, when also can be arranged to only take passenger 1 in lift car 2, produce the contrary sound equipment of phase place by loud speaker, and also can be arranged to only produce the contrary sound equipment of phase place when the noise of more than prescribed level being detected by loud speaker.Thereby, it is possible to prevent from unnecessarily making loud speaker produce sound equipment, the noise in lift car effectively can be reduced.
Be arranged in airspace for the microphone 4 that detects noise relative to lift car 2 toward the outer side (towards hoist trunk) arrange, and the loud speaker 7 producing the contrary sound equipment of phase place is configured to arrange towards the inner side of lift car.Thereby, it is possible to more effectively detect noise, the sound equipment corresponding to the noise detected can be produced.
In addition, loud speaker 7 is configured by car side plate to hide ventilation unit, makes the passenger 1 in lift car 2 can't see loud speaker 7, can prevent passenger 1 from moving back and forth loud speaker 7 etc. thus.Further, also can be arranged to utilize the decoration 14 etc. at lighting fixture or top to make the passenger 1 in lift car 2 directly cannot see loud speaker 7 loud speaker 7 at the top 10 of lift car 2, move back and forth loud speaker 7 to prevent passenger.
