Abstract

PURPOSE:To maintain the inside of a cage in a comfortable temperature environment while suppressing the equipment cost and running cost. CONSTITUTION:When elevator doors 14, 15 are opened, the ventilating fan 16 of a car 13 is started so as to take the air 12, conditioned to the suitable temperature in an elevator hall 11, into a cage, and when the elevator doors 14, 15 are closed, the ventilating fan 16 is stopped so as to keep the air in the cage from escaping. Comfortable environment can be obtained by thus taking almost the same air as in the elevator hall into the cage. In the stand-by state without a call for an elevator for the fixed time or more, a ventilation control device for the elevator opens the elevator doors 14, 15 periodically for the fixed time and starts the ventilating fan 16 of the car 13 so that the conditioned air 12 in the elevator hall 11 is taken into the cage. The temperature in the cage can be thus maintained at the suitable value even in the stand-by state.

The ventilation control device for the elevator is driven by the elevator operation control unit 1 to drive the elevator car up and down, the elevator motor 2, the door drive unit 3 for opening and closing the elevator doors, and the hall call hall hall. The hall call lamp on the operation panel is lit up, the car call inside the car room is illuminated, the car call lamp on the destination floor on the operation panel is lit up, and the elevator position is displayed on the elevator position indicator in the elevator hall on each floor. Display control unit 4 for displaying the elevator position on the elevator position indicator, a position sensor for detecting the position of the elevator car when it reaches the deceleration start position or when it reaches the stop position, the fully closed state of the elevator door, and the fully open state. Door sensor to detect the status, speed sensor to detect the speed of the elevator car , And a sensors 5, such as travel position sensor for detecting the position of the elevator during running.

As a feature of this embodiment, the ventilation control device for the elevator measures the timer A6 which is started when the elevator enters the stand-by state for a certain period of time after all the calls for the elevator are exhausted, and the drive time of the ventilation fan. It includes a timer B7 for operating, a ventilation fan drive unit 8 for driving a ventilation fan (described later) for a time defined by the timer B7, and a temperature sensor 9 for detecting the temperature inside the car.

Next, the mechanical structure of the elevator ventilation control system of this embodiment will be described with reference to FIG. 2. In the direction in which the ventilation fan 16 discharges the air in the car room to the ceiling of the elevator car 13. A temperature sensor 9 for detecting the room temperature is installed at an appropriate place in the car room. A control panel 18 for elevator control is installed in the machine room 17 at the top of the building, and most of the control circuit shown in FIG. 1 is housed therein.

Next, the operation of the elevator ventilation control device having the above-described structure will be described. First, the timer A6 is 5
Minutes, and timer B7 is set within a maximum of 3 minutes from the law. Further, the temperature range of the forced ventilation is set such that the forced ventilation is started when the temperature inside the car is 20 ° C. or lower in the winter and 25 ° C. or higher in the summer, for example.

Therefore, during normal operation, the operation control unit 1 drives and controls the elevator electric motor 2 in response to the hall call signal or the car call signal, moves the elevator car 13 to the hall call floor or the car call floor, and stops. The door drive unit 3 opens and closes the hold door 14 and the elevator door 15 which form the elevator door, and allows the user to get on and off.

Then, in synchronization with the opening timing of the elevator doors 14 and 15, the operation control unit 1 activates the ventilation fan 16 by the ventilation fan drive unit 8 so that the passengers can get on and off the elevator doors 14 and 15 completely. When the door is closed and the door closing signal is input from the sensors 5, the operation control unit 1
Gives a stop command to the ventilation fan drive unit 8, and the ventilation fan 1
Stop 6

As a result, as shown in FIG. 2, while the elevator car 13 arrives at any floor and opens the door,
The air in the car 13 is moved to the hoistway 19 by the ventilation fan 16.
The conditioned air 12 discharged into the elevator hall 11 is taken into the car 13.

Ventilation control when the elevator enters a standby state after a certain period of time has passed since the elevator was no longer called will be described with reference to the flowchart of FIG. Forcibly move the elevator to a floor that is pre-determined as the elevator is in a non-use time zone after a preset time, for example 3 to 5 minutes, has passed since all the hall calls and car calls for the elevator have disappeared. Control is made to wait. Therefore, the process of the flowchart is started when the operation control unit 1 enters the standby state.

First, when the timer A6 is started and its set time has elapsed (steps S1 and S2), the operation controller 1 reads the temperature detected by the temperature sensor 9 and determines whether it is within a predetermined temperature range. For example, in the summer, it is determined whether or not the comfortable room temperature is higher than 25 ° C, and conversely, in the winter, it is lower than 20 ° C (step S
3).

If the temperature is outside the predetermined temperature range,
The operation control unit 1 gives a command to forcibly open the door to the door drive unit 3 to open the elevator doors 14 and 15, and gives a ventilation fan start command to the ventilation fan drive unit 8 to provide an elevator inside the car 13. Air-conditioned air 12 in hall 11
To take in (step S4). Then, when the control of the forced ventilation is started, the timer B7 is activated, and the preset time is within 3 minutes at maximum (this time, the experiment is performed for each building depending on the capacity of the car 13 and the capacity of the ventilation fan 16). Is temporarily set and is variably adjusted), the forced ventilation is ended and the elevator doors 14 and 15 are closed (steps S5 to S).
7).

Thereafter, while the operation control unit 1 is in the standby state,
The forced ventilation control described above is repeatedly executed, and the indoor temperature of the car 13 becomes too high in the summer or too low in the winter. Make sure that the room temperature is maintained at a comfortable level even when you get on.

Thus, in the elevator ventilation control system of this embodiment, the appropriately conditioned air present in the living room of the building where the elevator is installed or in the elevator hall is always taken into the elevator car 13. It is possible to maintain a comfortable temperature state in the car room at low cost without separately providing costly equipment such as an air conditioner on the car room side. Moreover, the temperature sensor 9
Since the indoor temperature of the car 13 is detected by this and the ventilation fan 16 is driven only when the temperature is not within the comfortable temperature range, it is possible to achieve energy saving without wastefully starting the ventilation fan 16. You can

The time setting of each of the timers A and B in the above embodiment is not particularly limited, and can be adjusted depending on the environment around the elevator, the capacity of the car, the capacity of the ventilation fan, etc. It is a thing.

Next, another embodiment of the invention of claim 2 will be described with reference to FIGS. 4 and 5. The elevator ventilation control device of this embodiment has a configuration in which the temperature sensor 9 for detecting the room temperature of the car 13 used in the first embodiment is omitted, and the other circuit elements are the same as those of the embodiment shown in FIG. The same reference numerals are given to them.

6 is started / stopped, and when the elevator enters the standby state, the elevator doors 14 and 15 are periodically opened regardless of the room temperature to ventilate the car 13 for a certain period of time. . (Therefore, the mechanical structure is the structure in which the temperature sensor 9 is deleted in FIG. 2.) That is, as shown in the flowchart of FIG. When shifting to the standby state, the operation control unit 1 activates the timer A6, and when the set time has elapsed (step S11,
S12), the operation control unit 1 gives the door drive unit 3 a command to forcibly open the door to open the elevator doors 14 and 15, and gives the ventilation fan drive unit 8 a ventilation fan start command to the car 13 The conditioned air 12 in the elevator hall 11 is taken in (step S13). Then, when the control of the forced ventilation is started, the timer B7 is activated, and the preset time is within 3 minutes at maximum (this time, the experiment is performed for each building depending on the capacity of the car 13 and the capacity of the ventilation fan 16). Is set and is variably adjusted), the forced ventilation is ended and the elevator doors 14 and 15 are closed (steps S14 to S16).

Thereafter, while the operation control unit 1 is in the standby state,

It is possible to maintain a comfortable temperature state in the car room at low cost without separately providing costly equipment such as an air conditioner on the car room side.

In the above embodiment as well, the timer A,
The time setting for each B is not particularly limited, and can be adjusted depending on the environment around the elevator, the capacity of the car, the capacity of the ventilation fan, and the like.

Next, another embodiment of the invention of claim 1 will be described with reference to FIG. The elevator ventilation control device of this embodiment is a functionally simplified one, and does not consider whether or not forced ventilation is performed after the elevator enters the standby state, and is synchronized with the opening and closing of the elevator doors 14 and 15. The ventilation fan 16 is controlled to start and stop. Therefore, the timer A6, the timer B7, and the temperature sensor 9 are not provided, but other elements common to the embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals.

Also in the elevator ventilation device of this embodiment,
While the elevator is in operation, the operation control unit 1 responds to the hall call signal and the car call signal to drive the elevator motor 2
Is controlled to move the elevator car 13 to the hall call floor or the car call floor and stop, and the door drive unit 3 opens and closes the hold door 14 and the elevator door 15 to get the user on and off. Then, in synchronization with the opening timing of the elevator doors 14 and 15, the operation control unit 1 activates the ventilation fan 16 by the ventilation fan drive unit 8 and the elevator doors 14 and 15 are fully closed after the user gets on and off. ,
When the door closing signal is input from the sensors 5, the operation control unit 1 gives a stop command to the ventilation fan drive unit 8 to stop the ventilation fan 16.

As a result, as shown in FIG. 2, while the elevator car 13 arrives at any floor and opens the door,
The air in the car 13 is moved to the hoistway 19 by the ventilation fan 16.
The air-conditioned air 12 existing in the elevator hall 11 is taken into the car 13, and as long as the elevator is operating, the air-conditioned air 12 on the elevator hall 11 side causes the car 13 to be in the room. By replacing the air, it can be operated at a comfortable temperature.
