JPH0680775U - Elevator car ventilator - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a comfortable in-car environment without odor. [Composition] An exhaust fan 7 was attached to the skirting board 6 so that the operation of the exhaust fan 7 was controlled in accordance with the time zone for dust disposal in the housing complex.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation system for an elevator car, and more particularly to a ventilation system for an elevator car suitable for an elevator installed in a housing complex or the like where food waste is transported at a specific time.

[0002]

[Prior art]

 As a conventional device, as described in Japanese Utility Model Laid-Open No. 63-123571, an aroma device is attached to an elevator car, and when the elevator reaches a specific floor, aroma is generated in the car for a certain period of time. Alternatively, as described in Japanese Unexamined Publication No. 92-4523, the concentration of malodorous gas in a car was detected, and a deodorizing and neutralizing agent for malodor was sprayed.

[0003]

[Problems to be solved by the device]

 By the way, there are large individual differences in the response to ventilation, and it is doubtful that the synthesized odor is always comfortable when adding a strong odor to the residual odor to cancel it. In addition, the malodorous component is not constant, and it is almost impossible to detect its concentration with a simple device. Therefore, it is said that it is extremely difficult to create a neutralizing agent that scientifically decomposes this component. is there.

An object of the present invention is to provide an elevator car ventilation device that has a simple structure and is effective in removing malodors in the car.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to an elevator car ventilation system having an intake fan in the ceiling part of the car, in which an exhaust fan for exhausting air from a skirting part provided between the car floor and side plates is attached. The exhaust fan is operated every day for a certain period of time, and the intake fan is also operated at least during this operating time.

[0006]

[Action]

 According to this invention, an exhaust fan that exhausts air from the skirting board is installed so that the odor can be discharged to the lower part beyond the sense of smell by operating in accordance with the time when the garment is being discharged. Can be prevented from feeling.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a conceptual diagram of an elevator car, and FIG. 2 is a fan control circuit diagram.

In FIG. 1, 1 is an elevator car, 2 is a ceiling of the car 1, 3 is a floor, 4 is a side plate, 5 is an intake fan attached to the ceiling 2, 6 is provided between the side plate 4 and the floor 3. The baseboard 6 is an exhaust fan attached by cutting out a part of the baseboard 6.

In FIG. 2, (+) and (−) are control power supplies, F ₁ is a relay that sends a control signal to an intake fan, F ₂ is a relay that sends a control signal to an exhaust fan, and S is an excitation of relay F ₁ . Manual switches Ta ₁ and Ta ₂ are a-contacts of the timer T.

If the passenger 8 brings the garbage bag 9 into the car 1 during the time when the intake fan 5 and the exhaust fan 7 are currently operating, the air that flows into the car 1 by the intake fan 5 is exhausted. Since the fan 7 constantly exhausts the air as a downward air flow to the outside of the car 1, the malodor emitted from the dust bag 9 does not stimulate the passenger 8's sense of smell. Therefore, even during the above-mentioned time period, which has been a problem in the past, no passengers who use the car 1 are annoyed by the bad smell.

[0011]

[Effect of device]

 According to this invention, an exhaust fan that exhausts air from the skirting board is installed so that the odor can be discharged to the lower part beyond the sense of smell by operating in accordance with the time when the garment is being discharged. It is possible to provide a ventilation system for an elevator car that does not make people feel.
