Abstract

PROBLEM TO BE SOLVED: To provide an elevator device capable of preventing an unpleasant feeling from being given to passengers in a car caused by bad odor. SOLUTION: An elevator device is provided with an odor detector 1 operated when odor in a car 8 exceeds a specified value. This device is also provided with a deodorizing device 11 for discharging ozone in the car 8 and a deodorizing controller 27 operated according to the operation of the odor detector 1 and landing site calling made to the car 8 for energizing the deodorizing device 11. Thus, when bad odor in the car 8 exceeds the specified value, ozone is supplied into the car 8 by the deodorizing device 11 via landing site calling. Therefore, a passenger at an elevator landing site is prevented from entering the car 8 having odor. Also, since the deodorizing device 11 is operated only when necessary, power is saved.

Reference numeral 11 denotes a deodorizing device which is provided on the ceiling 9 and emits ozone into the car 8.
A controller 16 of a device such as an ozone generator 14, a blower 15,
A power supply 17 for supplying electric power to an apparatus such as an ozone generator 14 and a vibration-proof rubber 18 provided between the ceiling 9 and the deodorizing device 11
It is constituted by. Reference numeral 19 denotes an air diffusion device arranged in an opening 20 provided on one side of the ceiling 9, a large number of diffusion plates 21 and an adjusting arm 22 for changing the angle of the diffusion plates 21.
It consists of.

Reference numeral 23 denotes an intake port provided on the other side of the ceiling 9,
24 is a base of the intake port 23, 4 is a blower having a blower port connected to the diffusion device 19, and 25 is a deodorizer 11 and the suction port 23.
, An ozone supply pipe 26 connected to the blower 15 of the deodorizing device 11 and opening to the intake section of the blower 4, 1 an odor detector provided on the ceiling 9, 27 provided on the control panel 7 It is a deodorization control device.

In the elevator apparatus configured as described above, the elevator is controlled by the control panel 7 and the car 8 moves up and down the hoistway 5. In addition, the blower 4
Is energized and the air in the car 8 flows from the intake port 23 to the intake pipe 2.
5 and the ozone supply pipe 26, and is blown from the opening 20 of the ceiling 9. Then, the deodorizing device 11 and the like are controlled by the deodorizing control device 27 as shown in the flowchart of FIG.

That is, at step 101, the car 8
When the odor detector 1 operates when the bad smell in it exceeds a predetermined value,
Proceeding to step 102, if there is a hall call to the car 8, proceed to step 103. Then, in step 103, the deodorizing device 11 is activated. Then, the blower 15 is operated by the operation of the controller 16 in the deodorizing device 11, and the car 8
The air inside is sucked through the intake port 23, the intake pipe 25, the high-performance filter 12, and the cooling device 13. In addition, the ozone generator 14 operates to generate a predetermined amount of ozone, which is supplied from the ozone supply pipe 26 to the opening 20 of the ceiling 9.

When the deodorizing device 11 is energized, the ozone supplied with the air blown by the blower 15 is supplied to the diffusion device 1.
9 diffuses into the car 8 and is released. Next, proceeding to step 104, if the odor in the car 8 becomes less than the set predetermined value and the odor detector 1 becomes inactive, proceed to step 105 and deodorize the deodorizing device 11. Thus, the deodorizing action in the car 8 by the deodorizing device 11 or the like is completed. Note that the blower 4 may be operated as appropriate in summer, stopped in winter, or controlled together with the deodorizer 11.

In this way, when the malodor in the car 8 exceeds a predetermined value, ozone is supplied into the car 8 by the deodorizing device 11 or the like via the hall call. Therefore, it is possible to eliminate the problem that the passenger who was in the elevator 8 does not get into the car 8 that has not been deodorized and feels discomfort due to the bad smell. Further, since the ozone supplied into the car 8 is diffused and released by the diffusion device 19, the ozone can be quickly diffused to every corner in the car 8 and an effective deodorizing action can be obtained.

Further, the deodorizing device 11 is activated via the odor detector 1 and the hall call. For this reason, when the odor detector 1 is not operating and there is no hall call, the deodorizing device 11 does not operate and power can be saved. Also,
Since the deodorizing device 11, the blowing device 4, and the like are provided on the ceiling 9 of the car 8, the indoor space of the car 8 can be effectively used, and damage caused by mischief when the deodorizing device 11 is provided in the car 8. And the like can be prevented.

The amount of ozone supplied into the car 8 by the deodorizing device 11 is 0.1 pp considering the influence on the human body.
It is desirable to set it to m or less. In addition, the odor detector 1
Usually, a semiconductor gas sensor is used, but the above-mentioned action can be obtained by using another sensor for detecting odor, for example, a biosensor. In addition, the above-mentioned effect can be obtained by installing the odor detector 1 in an appropriate place where the odor can be detected, such as the wall of the car 8 or an operation panel (not shown) in the car, in addition to the ceiling 9 as the installation position. Can be.

In the configuration shown in FIG. 1, the air in the car 8 is supplied to the deodorizing device 11 through the intake pipe 25. Can be shortened or omitted.
In addition, the ozone of the ozone generator 14 is diffused from the ozone supply pipe 26 into the car 8 by the diffusing device 19 and released. The plurality of ozone supply pipes 26 are arranged at the corners of the ceiling 9 so as to be opened. It is also possible to arrange to discharge directly into the car 8.

The concentration of the ozone atmosphere supplied into the car 8 by the deodorizing device 11 is set to a constant value of 0.1 ppm or less. In addition, the concentration of ozone atmosphere supplied to the car 8 is set at 0. 0 depending on the loading amount of the car 8, the use of the building in which the elevator is installed, the degree of bad smell such as the environment of the elevator.
It is also possible to configure the apparatus so that it can be appropriately adjusted within the range of 1 ppm or less.

Further, according to the degree of the bad smell in the basket 8,
The apparatus is configured so that the ozone atmosphere concentration can be appropriately adjusted within the range of 0.1 ppm or less, and the air volume of the blower 15 is adjusted so that the air volume into the car 8 can be increased or decreased according to the ozone atmosphere concentration. It is also possible. Although one deodorizing device 11 is provided on the car 8 in the configuration of FIG. 1, a small deodorizing device is provided so that the entire ozone atmosphere concentration supplied into the car 8 is within a range of 0.1 ppm or less. The same operation as in the first embodiment can be obtained even with a device configuration in which a plurality of
