Problems solved by technology

However, if it takes time to recover due to a power failure or emergency stop, passengers will be locked in the car for a long time
At this time, if the car has an airtight structure, it will be difficult to ventilate the car, and in the worst case, the passengers may be deprived of oxygen.

Embodiment approach 1

[0026] figure 1 is an overall configuration diagram showing the elevator apparatus according to Embodiment 1 of the present invention, figure 2 It is a figure which shows the connection relationship of the ventilation opening 2 in the elevator apparatus 100, the ventilation opening monitoring apparatus 1, and the air pressure adjustment apparatus 3.

[0027] Such as figure 1 As shown, the elevator apparatus 100 according to Embodiment 1 includes a ventilation opening 2 for allowing air to enter and exit the airtight car 10 (a car with improved airtightness), and a ventilation opening 2 connected to the ventilation opening 2 and facing the ventilation opening 2 A ventilation port monitoring device 1 for monitoring, an air pressure adjustment device 3 connected to the ventilation port 2 to adjust the air pressure in the airtight car 10, a blower 7 for increasing and decreasing the air pressure in the airtight car 10, And the differential pressure gauge 9 that detects the air ...

Embodiment approach 2

[0053] Next, an elevator apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. Figure 6 It is a figure which shows the connection relationship of the ventilating port concerning Embodiment 2, a ventilating port monitoring device, and an air pressure adjusting device. In addition, in Embodiment 2, the same reference numerals are assigned to the same components as those in Embodiment 1, and detailed description thereof will be omitted.

[0054] Such as Figure 6 As shown, the main difference between the elevator apparatus according to Embodiment 2 and the elevator apparatus according to Embodiment 1 lies in that two monitoring contacts (second contacts) are configured in parallel and two in series, and that the power supply 11 Configure the ventilation ports as two in parallel (doubling).

[0055] That is, in Embodiment 2, the ventilation ports 2a and 2b are connected in parallel to the power supply 11 . Between the co...

Abstract

PROBLEM TO BE SOLVED: To provide an elevator device that can appropriately ventilate inside of a car not only during a normal operation but even when power failure or emergency stop, etc. occurs.SOLUTION: An elevator device includes: a ventilation hole 2 for ventilating inside of a car 10; a power source 11 for feeding electric power to the ventilation hole 2; an atmospheric pressure control device 1 for opening / closing the ventilation hole 2 and controlling atmospheric pressure in the car 10; a ventilation hole monitoring device 3 for opening / closing the ventilation hole 2 independently of the atmospheric pressure control device 1; a control contact 13 for connecting the power source 11 and the ventilation hole 2 with each other and connecting the atmospheric pressure control device 1 and the ventilation hole 2 with each other; a monitoring contact 12 for connecting the power source 11 and the ventilation hole 2 with each other and connecting the ventilation hole monitoring device 1 and the ventilation hole 2 with each other; and a ventilation hole opening / closing detection section 8 for detecting opening / closing of the ventilation hole 2. The monitoring contact 12 and the control contact 13 are connected in series. The ventilation hole monitoring device 1 opens the ventilation hole 2 via the monitoring contact 12 when the ventilation hole 2 is closed for a predetermined time.SELECTED DRAWING: Figure 1

Description

technical field [0001] The present invention relates to an elevator apparatus for adjusting air pressure in a car to ventilate the car. Background technique [0002] Conventionally, in high-rise buildings, long-travel and high-speed elevator devices have been used in order to improve the efficiency of movement in the building. In the above-mentioned long-travel high-speed elevator device, due to its moving speed, the air pressure per unit time in the car fluctuates greatly. For this reason, passengers in the car may feel unpleasant sensations of bloodshot ears or dizziness accompanied by large air pressure fluctuations. Therefore, in order to eliminate this unpleasant feeling, it has been proposed to control the air pressure in the car. [0003] In order to control the air pressure in the car of the elevator device, it is necessary to set the car as an airtight structure with improved airtightness and airtightness, so that the car can be pressurized and decompressed to pre...
