Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a car of a view elevator according to the present invention. A wall provided around a car floor 1 is provided with a window glass portion 2 provided so that the outside can be viewed from inside the car. ing. The window glass unit 2 is provided with a liquid crystal glass device 3 as a shielding device for limiting the amount of sunlight that enters the car from outside. The liquid crystal glass device 3 uses a dispersion type liquid crystal glass that makes the window glass portion 2 transparent and opaque by applying or releasing a voltage. When the elevator is running, the liquid crystal glass device 3 becomes transparent when a voltage is applied. When the operation of the elevator is stopped, during inspection, or when there is no call (stopped without an operation command) for a predetermined period of time, it becomes opaque because the amount of sunlight into the car is limited. The operation and non-operation of the liquid crystal glass device 3 can be switched by the user's intention.

Next, FIG. 2 is a view showing the principle of the dispersion type liquid crystal glass. There is a transparent conductive film 20 between the glass 21 and the glass 21, and there are liquid crystal molecules 23 and 24 in the capsule 22, and a power supply 25
When a voltage is applied, the glass is aligned in a certain direction, so that light can travel straight between the glass and the glass to be transparent. The liquid crystal molecules 23
Indicates a misaligned state, and the liquid crystal molecules 24 indicate an aligned state.

FIG. 3 is a flowchart for explaining the operation of the liquid crystal glass device 3 as a shielding device.

First, when the sun protection switch in the car of the observation elevator and the operation detection contact are turned on, and there is a call or the check switch is OFF, the window glass part 2 in the car of the observation elevator is made transparent. On the other hand, when there is no call when the sun protection switch or the operation switch is OFF or for a certain period of time, or when the inspection switch is ON, the window glass portion 2 in the car of the observation elevator becomes opaque.

FIG. 4 is a circuit diagram showing an embodiment of the present invention.

FIG. 4 shows a door closing confirmation relay a contact 41a which is turned on when the door is fully closed (not shown) between the DC power supply PN, an ascending direction detecting relay b contact 42b which is turned on when calling the ascending direction (not shown), and a descending direction call (not shown) There is a circuit in which a no-call detection timer consisting of a descending direction call detection relay b contact 43b that is turned on is operated, a sun protection switch 51 is provided between the AC power supplies R and T, the switch 51 is turned on, and turned on at the time of operation confirmation. When the operation detection relay a contact 44a is turned on and the inspection detection relay b contact 40b which is turned on at the time of inspection is also turned off and the above no-call detection timer 50 is turned off, a voltage is applied to the dispersed liquid crystal glass 60 in the basket. The window glass part 2 becomes transparent.

Conversely, the sun protection switch 51 is turned off or the operation detection relay contact 44a which is turned on at the time of operation confirmation is turned off, or the inspection detection relay b contact 40b which is turned on at the time of inspection is turned on or no call is detected. When the contact 50b, which is turned on after a certain period of time of the timer 50, is turned on, the dispersed liquid crystal glass 60 in the basket is
Since no voltage is applied, the window glass part 2 becomes opaque.

As described above, according to the present embodiment, the amount of sunlight into the car can be limited by the liquid crystal glass device 3 as the shielding device during the suspension of operation, so that the temperature in the car during suspension increases abnormally. Will not occur.

In addition, even during inspection, the amount of sunlight into the car can be limited by the liquid crystal glass device 2, so that the temperature inside the car can be prevented from rising, and the inspection work is not monitored from outside. The staff can be given a sense of security.

Furthermore, when a state without a call (a state in which there is no operation command and the apparatus is stopped) has passed for a predetermined time, the amount of sunlight in the car can be limited by the liquid crystal glass device 3, so that the temperature in the car can be reduced. Can be prevented.

Further, in the above embodiment, since the liquid crystal glass device is used as the shielding device, cutting off and releasing the voltage application of the liquid crystal glass device during inspection or during operation suspension leads to considerable power saving for the liquid crystal glass device. This is effective.

Furthermore, by switching ON and OFF of the sun protection switch, the shielding device can be operated or not operated, so that the shielding device can be operated according to conditions at the time of operation, When the view from the windowpane 2 is not required, by turning off the sunshade switch, the shielding device is made inoperative and the windowpane 2 can be always shielded.

[Effects of the Invention] As described above, in the control device for a prospective elevator according to the present invention, the shielding device for limiting the sunlight entering the car is provided. By shielding the glass part, the temperature inside the car can be prevented from rising, and even when a cooler is used, power consumption is kept low and energy can be saved.
