Technical field

The present invention relates to an elevator that ventilates a car at the time of a power failure of a regular power supply due to a failure of the elevator.

Background art

In recent years, with the rise of buildings, there has been a demand for faster rides and higher ride comfort. If the height of the building exceeds 300 m, passengers may be uncomfortable due to changes in air pressure during ascent and descent. In addition, very high speeds may have a physiological effect on passenger hearing.

Therefore, from the viewpoint of minimizing the above effects, a pressure control device that changes the air pressure inside the car according to the air pressure outside the car has been proposed.

In this elevator, as shown in Fig. 8, an air supply blower 2 for pressurizing the inside of the car 1 and an exhaust blower 3 for depressurizing the inside of the car 1 are provided at the top of the car 1 as shown in Fig. 8. For example, when descending from the top floor of a high-rise building to the lowest floor at a stretch, the first half of the descent drives the air supply blower 2 to control the pressure in the car 1 and the latter half of the descent makes the exhaust blower 3 is driven to reduce the pressure inside car 1.

That is, when the car 1 suddenly descends, the air pressure outside the car 1 changes as shown by a broken line in FIG. 9, and during the descent, the amount of pressure change per unit time greatly changes. Gives passengers hearing ability Since the physiological effect is large, the air supply blower 2 and the exhaust blower 3 are driven and controlled to reduce the physiological effect on the passenger's hearing function inside the car, and the air pressure inside the car 1 is the same. As shown by the solid line in the figure, the amount of pressure change per unit time is set to be constant.

However, in order to change the air pressure in the car 1 to an optimum state, it is necessary to increase the airtightness of the car 1.

Conventionally, the following two techniques for maintaining airtightness have been considered as techniques for improving the airtightness of car 1. One of these technologies is a technology that closes the gap between the cab 1 and the door panel by covering the intersection between the cab 1 of the car 1 and the door panel. No. 1), there is a technique in which the force of the car 1 is formed in a curved shape from the passenger compartment to the door panel side, and an adhesive material is provided so as to adhere to the door panel side (JP-A-6-24). 7 6 7 5).

However, in the above technologies, the purpose is to completely block the air inside and outside the car, and because of the failure of the elevator, the power was cut off while the passengers were trapped. That is not considered. When electric power is supplied to the car from a regular power supply that is normally used, air supply and exhaust can be performed by driving the air pressure control blowers 2 and 3, so the car has insufficient oxygen. It does not happen.

However, there is a possibility that the regular power supply will be interrupted according to the details of the failure. In such a situation, the drive control of the air pressure control blowers 2 and 3 becomes impossible, and Because the car itself has a highly airtight structure, if ventilation in the car becomes impossible, the oxygen concentration in the car will decrease, not only giving passengers discomfort but also safety. There is a possibility that it may be damaged.

Disclosure of the invention

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an elevator that realizes ventilation in a car at the time of a power outage of a regular power supply due to a failure of an elevator, thereby ensuring passenger safety. I do.

The elevator according to the present invention includes a car configured to maintain airtightness, a main power supply for driving the car, and a power supply from the main power supply, which controls an air pressure inside the car. And a unit that operates when the main power supply fails and ventilates the car.
