Abstract

PURPOSE:To reduce a chimney effect of an elevator shaft by arranging a smoke sensor on the respective floors of a house, and operating a landing car to a fire causing floor when the smoke sensor is operated. CONSTITUTION:When a fire is caused on the second floor, a smoke sensor 12B is operated. By this operation, an always opening contact point of the smoke sensor 12B is turned on, and an ancillary relay of the smoke sensor 12B is excited. Then, an always opening contact point of this ancillary relay is closed, and a commanding circuit is operated, and a landing car 4 is operated to the second floor. Thereby, even if smoke tries to enter an elevator shaft from a floor entrance door 10 on the second floor, since it is checked by a landing car entrance door 5 or the landing car 4, the inside of the elevator shaft 2 does not cause a chimney effect, so that a fire does not spread.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential facility equipped with a home elevator.

[0002]

2. Description of the Related Art Recently, in order to solve housing difficulties, two generations,
It is recommended that three generations live in the same house, and the number of two-story and three-story private houses in which this type of generation lives together is increasing. Considering the problems associated with going up and down the stairs for moving people with disabilities such as the elderly living in these houses to the upper and lower floors, for example, as shown in Japanese Utility Model Publication No. 62-26370, Home elevators for two-story, three-story houses, etc. have been proposed and used in part.

[0003]

In the above-mentioned prior art, no consideration was given to a fire. That is, if a fire occurs on the second floor, for example, if the car is on the first floor, smoke enters the hoistway through the floor entrance door on the second floor, and this hoistway creates a chimney effect, which causes a larger fire. There is.

An object of the present invention is to provide a residential facility equipped with a home elevator which can reduce the stack effect of a hoistway.

[0005]

[Means for Solving the Problems] The above-described object is to provide a housing facility having a two-story or more house with a hoistway and a home elevator having a car that moves up and down in the hoistway. This is achieved by providing smoke detectors on each floor and providing means for operating the car to the fire floor when the smoke detectors are operating.

[0006]

When, for example, the smoke detector on the second floor operates, the car moves to the second floor and blocks smoke from entering the hoistway. This prevents the hoistway from becoming a chimney effect and does not increase the fire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a housing facility equipped with a home elevator according to an embodiment of the present invention, and FIG. 2 is a circuit diagram for operating a car to a fire floor.

In the figure, 1 is a house, for example, a three-story private house, 2 is a hoistway standing inside the house 1, 3 is a plunger that can move up and down in a cylinder (not shown), and 4 is a plunger. A car 5 which is fixed to the upper end of 3 and moves up and down in the hoistway 2 is a door 5, 6 and 8 provided on the car 4.
Is the floor of the house 1, and 9, 10 and 11 are the entrance doors of each floor. 12A to 12C are ceilings 13 to 15 on each floor
The contacts 12Aa to 12Ca are turned on by the operation of the smoke detectors 12A to 12C. 16A to 16C are relays, 16Aa to 16C
Reference numeral a is a contact which is turned on when the relays 16A to 16C are excited, and 17A to 17C are command circuits for operating the car 4 to the operation floor of the smoke detectors 12A to 12C.

Now, when a fire occurs on the second floor, the smoke detector 12B operates. The operation of the smoke detector turns on the contact 12Ba to form a (+)-12Ba-16B-(-) circuit, and the relay 16B is excited. As a result, the contact 16Ba is closed, and (+)-16Ba-15B-
The command circuit 15B operates by the circuit configuration of (-), the car 4 operates to the second floor, and the state shown in FIG. 1 is obtained. This allows smoke to enter the hoistway 2 through the floor door 10
The hoistway 2 is blocked by the car door 5 and car 4
It does not create a chimney effect and does not increase the fire.

[0010]

According to the present invention, since the car is operated to the fire floor, the hoistway is prevented from having a chimney effect and the fire is not increased.
