Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation fan operation control device that operates and stops a ventilation fan provided in a dust chute in accordance with opening and closing of an inlet opening/closing lid of the dust chute.

Conventionally, a dust chute with a dust inlet is installed on each floor of a building in order to dispose of the dust generated in the building as one type of dust treatment equipment.The end of the dust chute is connected to a compactor, and the dust is fed through the inlet. Instead of a structure in which the waste is packed into a container by the compactor and then transported to a treatment plant, this dust chute is equipped with an opening/closing lid over the waste inlet, and a ventilation fan is installed at the top.
The odor emitted by the garbage is released outside the building, but the ventilation fan is turned on by the operator's switch before starting the garbage treatment, and is turned off after the process is finished.
If workers dispose of garbage without operating the ventilation fan, odors will enter the building when the opening/closing lid is opened, and the ventilation fan may continue to operate without stopping even if the opening/closing lid is closed at the end of work. Problems were rare.

The present invention has been made in view of this point, and the ventilation fan provided at the top of the dust chute is activated when at least one of the dust chute lids on each floor is opened, and all the lids on each floor are opened. To provide a dust chute ventilation fan operation control device that stops operating when the dust chute is closed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

As shown in Figure 1, 1 is a garbage processing device that collects the garbage generated in the building 2 in one place and carries it out. A dust chute 4 having a dust chute 3 is provided, and the dust inlet 3 is provided with an opening/closing lid 5. Also, on the lowest floor, an extrusion port 6 is opened in the front, a feeding lower is opened in the upper surface, and an internal cylinder is opened. A plate compactor 10 is installed in which a ram 9 connected to a ram 8 reciprocates and pushes out dust from the extrusion port 6, and the end of the dust chute 4 is connected to the feeding lower.

A container 11 is connected to the extrusion port 6 and garbage is packed therein, and when the container 11 is full, it is loaded onto a transport vehicle and transported to a garbage disposal site.

Further, a ventilation fan 12 is installed at the upper end of the dust chute 4 to release the odor emitted by the dust to the outside of the building 2.

The detection means for emitting the opening/closing signals are respectively connected to the garbage inlet 3.
It has an open signal transmitter 14a that emits an open signal when the lid 5 is opened, and a close signal transmitter 14b that emits a close signal when the lid 5 is closed.

All of the open signal transmitting parts 14a are connected to a first OR circuit 17, the first OR circuit 17 is connected to a first AND circuit 18, and the first AND circuit 18 is connected to an operating switch 19 of the garbage processing device 1. First memory circuit 20
and is connected to the operation control circuit 15 via a second memory circuit 21.

The first for circuit 17 sends a signal to the first and circuit 18 when an open signal is issued from one of the open signal transmitting parts 14a, and the first and circuit 18 closes the operation switch 19 and outputs the output signal of the first or circuit 17. The first
A signal is sent to the memory circuit 20, the first memory circuit 20 stores the signal and sends the signal to the second memory circuit 21, and the second memory circuit 21 stores the signal and sends the signal to the operation control circuit 15. , the operation control circuit 15 operates the ventilation fan 12 in response to the input of the signal.

On the other hand, all of the closure signal transmitting parts 14b are connected to a second AND circuit 22, the second AND circuit 22 is connected to a third AND circuit 23, and the third AND circuit 23 is connected to the first memory circuit 20 and a first timer. 24 and 2nd o
It is connected to the stop control circuit 16 via the r circuit 25, the stop control circuit 16 is connected to the first memory circuit 20, and the second OR circuit 25 is also connected to the second memory circuit 21.

The second AND circuit 22 sends a signal to the third AND circuit 23 when all of the closure signal transmitting parts 14b issue a closure signal, and the third AND circuit receives the output signals of the second AND circuit 22 and the first storage circuit 20. A signal is sent to the first timer 24, and the first timer 24 sets the time until the compactor 10 packs all the garbage into the container 11 after all the opening/closing lids 5 are closed.
When the output signal No. 3 is input, the operation starts, and when the set time has elapsed, the output signal is sent to the stop control circuit 16 and the second memory circuit 21 via the second OR circuit 25, and the second memory circuit 2
The output signal of No. 1 is stopped, the stop control circuit 16 sends the stop signal to the first storage circuit 20, and the output signal of the first storage circuit 20 is stopped.

Further, the first memory circuit 20 is connected to the second memory circuit 20 via the second timer 26.
The second timer 26 is connected to the OR circuit 25 and stops the operation of the ventilation fan 12 when the opening/closing lid 5 is not closed at the end of the work of putting dust into the dust chute 4.
The time required for all garbage processing is set, and the first memory circuit 2
When an output signal of 0 is input, the operation starts, and after a predetermined period of time, the signal is sent to the stop control circuit 1 via the second OR circuit 25.
6 and the second storage circuit 21.
