Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an air conditioner for an escalator, and in particular to a handrail for supplying cold air or hot air to conveyed objects such as passengers on a stairway conveyor. This invention relates to an air conditioning system for an escalator that has an air conditioning duct inside the structure.

(Prior Art) Generally, escalators installed in buildings are air-conditioned to air-condition the entire room or passageway in which the escalator is installed.

In other words, the outlet of the air conditioner is provided facing the room or passageway in which the escalator is installed, and cold or warm air is blown out from the outlet to cool or heat the entire room, or the entire passageway. Air conditioning was provided to the passengers.

(Problem to be solved by the invention) However, it is difficult to create a cavity for escalators (including horizontal movement) for outdoor communication at airports, stations, etc., and when air conditioning is required, the escalator passage must be constructed with an airtight dome structure. This dome structure must be covered with air conditioning ducts, exhaust ducts, etc., which increases the equipment cost of the air conditioner.

Furthermore, escalators in nursing homes or resort condominiums are often empty when there are no passengers on them, so in order to provide comfortable air conditioning to the passengers, the entire room or passageway in which the escalator is installed must be constantly air-conditioned. However, this has led to an increase in the operating costs of the air conditioner.

The purpose of the present invention, which was created to solve the above problems, is to
By installing an air conditioning duct inside the handrail structure of the escalator to supply cold or warm air to passengers and other conveyed items on the stairway conveyor, the air conditioning effect is large regardless of where the escalator is installed, reducing equipment costs and operation. The present invention provides an air conditioning system for escalators that can reduce costs.

Further, the third invention provides a cold air duct for blowing cold air onto the stair conveyor of the escalator at the upper part of the handrail structure of the escalator, and a hot air duct for blowing hot air onto the stair conveyor. It consists of a handrail installed at the bottom of the structure.

(Function) In the first invention, the air conditioning duct provided in the handrail structure of the escalator blows cold or warm air directly toward the conveyed objects such as passengers on the stair conveyor. directly cools or heats the air.

Therefore, it is possible to provide desired cooling or heating to conveyed objects such as passengers on the escalator installed in any location without providing an airtight dome or the like for air conditioning to cover the escalator.

Further, in the second invention, the control means controls the air conditioning duct provided in the handrail structure according to a signal from a sensor that detects the presence or absence and position of a conveyed object such as a passenger on the stairway conveyor. Open and close the air outlet facing the object.

In other words, as the stair conveyor moves, the air outlets facing the conveyed object are sequentially opened and closed in order to blow out cold or warm air toward the conveyed object on the stair conveyor, so that cold or warm air is always spot-on towards the conveyed object. air supply and provide the desired cooling or heating.

At this time, since only the area around the transported object is spot-conditioned as the transported object moves, the transported object can be effectively cooled or heated, and an air conditioner with a small capacity can be used.

Further, in the third invention, cold air is blown from a cold air duct provided at the upper part of the handrail structure of the escalator toward the upper part of the conveyed object such as a passenger on the stair conveyor, and the cold air is blown inside the handrail structure. Cold air is blown out from a hot air duct provided at the bottom of the vehicle toward the bottom of the passengers and other objects to be transported.

Therefore, it is possible to perform air conditioning to reduce the temperature of the head and feet depending on the part of the passenger that feels warm.

The cold air duct 5a at the top of the air conditioning duct 5 is provided with a cold air nozzle 7a that blows cold air toward the chest area of the passenger 6, and the warm air duct 5b at the bottom is provided with a hot air nozzle that blows hot air toward the feet of the passenger 6. 7b is provided.

According to these ducts 7a and 7b, it is possible to perform air conditioning to keep the head cold and feet warm according to the part of the passenger 6 that feels warm.

[Effects of the Invention] As explained above, according to the present invention, the following excellent effects can be exhibited.

(1) No matter where the escalator is installed, it can be effectively installed by blowing cold HA or warm air directly from the air conditioning duct installed in the handrail structure towards passengers and other conveyed items on the stairway conveyor. In addition, it is not necessary to provide an airtight dome for air conditioning to cover the escalator, and the cost of air conditioning equipment can be reduced.

(2) As the 111-stage conveyor moves, the control means sequentially opens and closes the outlets of the air conditioning duct facing the conveyed object, and spot air-conditions only the area around the conveyed object, thereby achieving an effective effect using a low-capacity air conditioner. It is possible to achieve efficient cooling or heating, and it is also possible to improve energy saving.

(3) By blowing cold air from the cold air duct inside the handrail structure to the upper part of the conveyed object on the stairway conveyor, and by blowing hot air to the lower part of the conveyed object from the hot air duct, the passenger who is the conveyed object can feel the warmth. It is possible to achieve air conditioning that cools the head and warms the feet depending on the area.
