Abstract

PURPOSE:To keep the inside of a cage in fresh state even if it is used for the transport of dust by opening a door for a prescribed time and driving ventilating fan each time when a cage stops unless a call is generated, in a ventilating fan device installed in the cage of an elevator. CONSTITUTION:The time region for the transport of dust is set on a timer X, and all-time opened contact points Xa and Xb are closed within this time region. When no calling is generated, the all-time contact points Ya and Yb of a standard floor return device Y are closed by a standard floor return comple tion signal. Accordingly, a circuit of P-1b-Xa-Ya-Tb-M-N is closed and a ventilat ing fan turns. While, a circuit of P-Ta-Xb-Yb-Z-N is closed, and a door opening controller Z operates. Since the door of an elevator is opened, and the ventilat ing fan turns, the air in a cage is discharged outside the door. When the timer T completes the set time limit, the all-time closed contact points Ta and Tb are opened, and the ventilating fan stops. The door opening controller Z carries out the door closing operation at the completion of the self set time limit.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement in a ventilation fan device provided in a car.

<Prior art> Inside the elevator car, for example,
A ventilation system as shown in Publication No. 75 is provided.

This ventilation system is used for calibration to air-cool the inside of the car during the hot summer months, and for ventilation when the car is full of passengers.

<Problems to be Solved by the Invention> Now, in high-rise apartment complexes, elevators are used to transport garbage generated within each household out of the building. For this reason, there is a problem in that the odor generated from the garbage is trapped inside the basket, causing discomfort to other users.

By the way, in the summer, since the ventilation system is activated as mentioned above, the odor generated from the garbage is immediately removed from the basket by this ventilation system, so it is not as much of a problem. However, in the winter, when the ventilation fan is turned on, it gets cold and is not used.
For this reason, the odor generated from the garbage remains inside the car, which is extremely unpleasant for the passengers.

Therefore, the present invention has been made in view of these circumstances, and its purpose is to keep the inside of the basket fresh even after it has been used for transporting garbage. An object of the present invention is to provide an elevator operating device.

Means for Solving the Problems> The elevator operation device according to the present invention is equipped with a ventilation fan device in the car, and has means for detecting a predetermined time after the car stops and there is no more call. There is. A ventilation fan device responsive to the detection means is disposed within the car, and a door opening control means responsive to the detection means extends the door opening time.

In this invention, each time the car stops, the door is opened for a predetermined period of time and the ventilation fan is driven unless a call occurs. Therefore, even after being used for transporting waste,
Odors inside the car are immediately discharged to the outside of the car, allowing the inside of the car to be kept fresh and preventing discomfort from being caused to passengers who will use the car next time.

<Example> Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a circuit configuration diagram showing an embodiment for explaining the present invention. In the figure, P and N are power supply buses, and la and lb
are a normally open contact and a normally closed contact of a relay (not shown) that is energized when it detects that there is a call to the elevator, respectively.
T is controlled based on the normally closed contact 1b, and this normally closed contact 1
When b is closed, counting starts and continues for a predetermined time, e.g. 5
A timer configured to emit an output signal indicating that a normally closed contact 1b is closed for a minute, Ta and Tb are the normally closed contacts, respectively, and 2a is a ventilation fan installed in the operation panel inside the elevator car and described later. The changeover switch X sets the motor in a driveable state, and the time period during which garbage is transported is set, and the normally open contacts Xa and Xb, which are the output signals, are closed at that time period. For some clock devices, and in normal cases, this time period is from 10 a.m. to 1 a.m.
1 o'clock, and this time slot can be set arbitrarily according to the usage time. When the elevator is no longer called, an operation command is issued to return to the standard floor, and the A standard floor return device that outputs a signal when the elevator completes returning to the standard floor.
Yb is the normally open contact, Z is the door opening control device for extending the elevator car door opening for a predetermined period of time, for example 3 minutes, Xa and Xb are the normally open contacts, and M is the aforementioned ventilation fan drive motor. , and the above are connected as shown in the figure.

Next, the operation of a specific example of the embodiment with such a configuration will be described.

Now, in a high-rise apartment complex, the morning dispatch time has passed.
At 10:00 a.m., for example, if garbage collection trucks are making their rounds during this time, each household will take their garbage to the elevator during this time.
Start transporting using.

When this time period comes, the clock device X outputs a signal Xa,
Xb is being issued, and the frequency of use of elevators during this time is also the lowest in 24 hours, excluding midnight, as can be seen from the composition of the residents of the area. Therefore, once an elevator is used, a considerable amount of time passes before it is used again. Therefore, the number of times the call detection relay is operated is reduced, and the probability that its normally closed contact 1b is closed is increased. Therefore, if the call detection relay that detects the above-mentioned call is not activated between the time the elevator is used and the next time it is used, when the timer T counts the set time period by the normally closed contact 1b, The normally closed contacts Ta and Tb, which are the output signals, are released. In addition, in this state, in this embodiment, the elevator operation device is equipped with a reference floor return device Y when there are no more calls, so the reference floor return device Y is activated. hand,
The elevator travels toward the reference floor, and when the elevator car returns to the reference floor, the reference floor return device Y sends a normally open contact Y, which is a reference floor return completion signal.
a and yb are closed. Based on this operation, the ventilation fan motor M has P-1b-Xa-Ya-T
The b-M-N circuit is closed and power is supplied to drive the ventilation fan, thereby rotating the ventilation fan. On the other hand, a P-Ta-Xb-Yb-Z-N circuit is formed, the door opening control device Z is activated, and the elevator door is operated until the activation time limit of the door opening control device Z is reached. For this reason, the elevator door is open during this time, and the ventilation fan is rotating, so the air inside the elevator car is exhausted outside by the wind force from the ventilation fan. It turns out. If the condition of the elevator before this situation was that it was used by occupants to transport garbage, the odor emitted from the garbage would be absorbed during this period while no passengers were present, due to the operation described above. When the timer T finishes counting the set time period, the normally closed contacts Ta and Tb are opened.
The ventilation fan motor M thereby stops its rotation.

On the other hand, before the normally closed contact Ta is opened, the door opening control device 22 issues a command to perform the door closing operation after the time limit set in its own device expires, and the elevator door is closed. . However, even if such an operation is performed, the door is opened and the ventilation fan is rotated before that, so the air inside the car flows through the car entrance and exit, and the air inside the car is Since the garbage is in a fresh state, even if the next passenger to use the elevator enters the car, the odor generated from the garbage will be eliminated, and this user will not feel uncomfortable. .

Furthermore, if a call occurs while the door opening operation is being extended by the door opening control device Z before the time limit of the timer T expires, the timer T activates the above-mentioned call detection relay to activate the door opening operation. When the normally closed contact Ta is released, the door opening control device Z stops its operation, immediately closes the door, and performs the service of traveling to the operated floor.

In this embodiment, as mentioned above, a specific time period,
That is, since the above-mentioned operation is performed only from 10:00 a.m. to 11:00 a.m. as explained in this embodiment, the elevator
Because the car is stopped for a long time and the occurrence rate of calls is lowest, it allows the necessary time for the odor to flow out from inside the car, ensuring that the car is safe for the next person to use. It is possible to freshen the air inside. Therefore, it has become possible to realize an elevator that does not cause discomfort to users even in winter.

On the other hand, in this embodiment, the above-mentioned operation is performed only on the standard floor facing the outdoors. It also has the effect of preventing odors generated from being trapped.

Furthermore, in this embodiment, by operating the changeover switch 2a, when a passenger makes a call when using the elevator in the summer, the above-mentioned call detection relay that detects the call is activated. The normally open contacts 1a are energized, and power is supplied to the ventilation fan motor M, so that the ventilation fan rotates to ventilate the air inside the car and provide cold air to the passengers. This allows passengers to use the elevator in comfort.

In this way, in this embodiment, the inside of the car can be kept fresh at all times, and users can now use the elevator in comfort.

It goes without saying that the present invention is not limited to this embodiment, and that there are other embodiments as described in the claims.

<Effects of the Invention> As explained above, the present invention can reliably prevent odors generated from garbage from accumulating in the elevator car even after the elevator is used for transporting garbage. In addition, there is an effect that the elevator can always be provided in a comfortable condition to the users.
