Abstract

PROBLEM TO BE SOLVED: To prevent a passenger from feeling uncomfortableness caused by dust, by stopping the operation of a dust removing device when load to be detected by a car load detecting device exceeds a set value. SOLUTION: A load detecting device composed of a load sensor 8a and a control part 8b is installed on the floor of a car 1 of an elevator. When load not more than the set load, for example, 120kg is detected by the load sensor 8a, a contact of the load detecting device built in the control part 8b is released. The contact of a dust removing device is opened, a switch 7 is turned off, and the operation of the fans 2, 2a is stopped. The load detecting device is always electrified, when the detected load is less than the set load, the switch 7 of the dust removing device is turned on, a timer 9 is operated, and the fans 2, 2a are driven. When a passenger gets on the elevator, scattering of dust is prevented by stopping the dust removing device, and uncomfortableness can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car provided with a dust removing device for scattering, for example, an object to be conveyed in a car of an elevator or dust attached to a person in a dust removing chamber.

[0002]

2. Description of the Related Art As described in JP-A-6-239567, in a car of an elevator of a building where a clean room for producing semiconductors, electronic members, etc. is present, it is attached to an object to be conveyed including an operator. An apparatus has been proposed that removes dust that is present by blowing air.

[0003]

By the way, in the above-described conventional apparatus, when a passenger is present when using the elevator, when the conventional apparatus is operated, dust is scattered to the passenger and the passenger is not allowed to operate. It could be uncomfortable.

An object of the present invention is to provide an elevator car in which the operation of the device is prohibited when a passenger is present when using the elevator, and the passenger is not uncomfortable.

[0005]

SUMMARY OF THE INVENTION The above object is to provide an elevator car having a car load detecting device for detecting a load and a dust removing device for scattering dust adhering to an object to be transported by blowing air. When the object to be conveyed enters the car and the load detected by the car load detection device exceeds a predetermined value set in advance, the operation is interlocked with and the operation of the dust removing device is stopped to prevent operation. This is achieved by providing means.

As described above, when the passenger is using the elevator, the operation of the device is prohibited, so that the passenger is not uncomfortable due to dust scattering or the like.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an elevator car according to the present invention will be described below with reference to the drawings.

FIG. 1 is an overall view of an embodiment of an elevator car according to the present invention. FIG. 2 is a cross-sectional view taken along the line XX 'of FIG. FIG. 3 is a circuit diagram of essential parts showing an embodiment of the elevator car of the present invention.

In this embodiment, as shown in FIG. 1, clean air is blown out into a car 1 of an elevator, and a hollow container 5 standing vertically in the car and a car 5 in the car. Support means 6 having presser portions 6c and 6f for detachably mounting on the shaft, shaft portions 6a and 6d, and fixing nuts 6b and 6c, and air outlets 5a and 5b provided in the central portion of the storage body 5. Intake ports 2 provided at both ends of the storage body 5
d, 2f, filters 2c, 2e provided inside the intake ports 2d, 2f, respectively, and a switch 7 are installed.

Inside the housing 5, the fan 2 is arranged so that the discharge ports thereof are aligned with the air outlets 5a and 5b.
a, 2b and the fan 2a, and mix the deodorants 3c, 3d into the clean air.
a and 3b and a deodorant 3c and 3b, and a deodorizing device 3,
It is composed of a timer 9 located below the filter 2d.

In this embodiment, as shown in FIG. 1, first, the fans 2a and 2b and the deodorizing device 3 are provided in the car 1.
Is installed, and the shaft portions 6a and 6b are rotated to expand and contract, and the pressing portions 6c and 6f are brought into contact with the ceiling and floor of the car 1 and fixed by the fixing portions 6b and 6e, Supports the storage body 5.

On the floor of the elevator car 1,
A load detection device 8 is installed in a space between the car 1a and the frame 1b, and is composed of a load sensor 8a and a control unit 8b. When the load sensor 8a detects a predetermined load or more, it is built in the control unit 8b. The contact 8c of the load detection device 8 is opened, and when the load sensor 8a detects less than a predetermined load, the contact 8c is closed. And
Contact 8c of load detection device 8 and contact 9a of dust removal device
Are connected in series.

Next, the operation will be described.

As shown in FIG. 3, the load detecting device 8 is constantly energized, and when the total weight of the passengers in the car 1 of the elevator is less than 120 kg, the load sensor 8a of the load detecting device 8 is detected. Detects that the load is less than a predetermined load, and the contact 8c in the controller 8b is in a closed state. When the passenger turns on the switch 7 of the dust removing device, the contact 9a of the timer 9 is closed and the fans 2a and 2b are closed.
At the same time as the rotation, the timer 9 starts counting for 15 seconds.

When the fan 2a rotates, the blade portion 2h of the fan 2a rotates counterclockwise. When the wing portion 2h rotates, air is sucked in through the spaces 5c and 5d and blown out from the air outlet 5a.

At the same time, since the solenoid valve 3a is closed to open, the volatile component 3c of the deodorant 3b diffuses into the container 5.

On the other hand, by the rotation of the fans 2a and 2b, the air in the car 1 is sucked and passes through the intake ports 2d and 2f and the filters 2c and 2e, and the dust is removed by the filters 2c and 2e. Then, the air from which dust has been removed is guided to the gaps 5c and 5d and mixed with the volatile components of the deodorants 3c and 3d, and the air pushed out by the fans 2a and 2b is guided to the air outlets 5a and 5b, respectively. It is blown out of the storage body 5 at a flow velocity of 10 m / sec or more and is blown onto the clothes of passengers.

The volatile components of the deodorants 3c and 3d act on the odor adsorbed on the clothes, and the deodorizing effect is exerted, and the dust adhering to the clothes is also removed, so that the odor adheres. The service for passengers can be improved.

Further, since the dust scattered in the car 1 of the elevator is guided to and adheres to the intake port 2d or 2f while the dust removing device is operating, the car 1 is kept hygienic. .

Further, since the storage means 5 is provided with the support means 16 for detachably mounting it in the car 1, it can be mounted without depending on the height of the car 1 and can be stored in the car 1. The body 5 can be stably installed.

After 15 seconds, the contact 9a of the timer 9
Is opened, the rotations of the fans 2a and 2b are decelerated and stopped.

Next, when the total weight of the passengers in the elevator car 1 is 120 kg or more, the load sensor 8a of the load detecting device 8 detects that the weight is less than 120 kg, and the inside of the control unit 8b is detected. Since the contact point 8c is opened, even if a passenger in the car 1 of the elevator turns on the switch 7 of the dust removing device, the fans 2a and 2b are not energized and are in a stopped state, so the dust removing device operates. do not do. When the load sensor 8a of the load detection device 8 detects that the weight is less than 120 kg, it is determined that there is a passenger in the car 1 of the elevator, and the passenger tries to operate the deodorizing air supply device by the switch 7. Since it cannot be operated, it does not cause discomfort to other passengers.

When the passenger subsequently descends and the total weight becomes less than the predetermined load, the load sensor 8a of the load detecting device 8 detects that the load is less than 120 kg, and the contact point 8c in the control section 8b is detected. Closed.

[0024]

As described above, when the passenger is present when using the elevator, the operation of the device is prohibited, so that the passenger is not uncomfortable due to dust scattering or the like.
