Next, each operation of the interlock of the inbox 4 will be explained by taking as an example a state in which the doors on the front room side and the patient room side are all closed in this embodiment.

First, turn on the power switch provided on the operation panel 40 on the side of the front room to turn on the pilot lamp E and supply current to the conductor and the shunt. In this state, the germicidal lights 9 and 91 are turned on, and the timer D is activated, and after a predetermined period of time, the contact _D2 is turned off, the contact _D1 is turned on, and the germicidal light is turned off. Timer D then automatically returns to operate for the set time. On the other hand, the latch portions 61..., 71... of each door 41..., 51...
is engaged with each electric lock 6..., 7..., and even if you simply pull the handle 43..., 53..., each electric lock 6...
Each pushbutton switch 62 connected to ..., 7...
Since 72... is in the off state, each electric lock 6..., 7
... does not operate and each door 41..., 51... cannot be opened.

Next, when the push button switch 72 on the front chamber side is pressed, the normally open contact 721 is turned on, and the normally closed contact 721 is turned on.
22 is turned off. As a result, the normally closed contacts 621 of the limit switch 81 on the patient room side, the electric lock 7 on the front room side, and the push button switch 62 on the patient room side connected to the shunt R ₃ are energized because they are in the on state. The equipped buzzer sounds and indicates that the electric lock 7 on the front chamber side is in an unlocked state. In this state, the door 51 is opened by pulling the handle 53. Then, the front chamber side limit switch 82, which was in contact with the back surface of the door 51, is turned off. On the other hand, the door 51 is opened in this way, and the push button switch 72 on the front chamber side is opened.
Even if the handle 43 is pulled in an attempt to release the hospital room door 41 in the restored state, the hospital room electric lock 6 is in the OFF state and the latch portion 61 is engaged.
The door 41 cannot be opened, and even if the patient room side push button switch 62 is pressed and the normally open contact 622 is turned on, the front room side limit switch 82 connected to this cannot be opened.
is in the off state, the electric lock 6 on the hospital room side is not energized and remains locked, and the door 41 is not opened and the buzzer does not sound, indicating that it is locked, and the handle 43 is pulled indiscriminately. Nothing happened. The same holds true even when the push button switch 72 on the front chamber side is pressed.

Next, when closing the door 51 on the front chamber side, even if the electric lock 7 on the front chamber side is in the locked state, the latch portion 7
Due to the kicking action using the spring 1, the door 51
is closed, and the front chamber side limit switch 82 returns to the on state.

In this state, when the door 41 on the patient room side is to be opened next, when the push button switch 62 on the patient room side is pressed, the normally closed contact 621 is turned off and the normally open contact 622 is turned on. As a result, the normally closed contacts 722 of the hospital room side electric lock 6, the front room side limit switch 82, and the front room side push button switch 72, which are connected in parallel with the shunt R ₃ , are in the on state, so they are energized, and the hospital room side electric lock is energized. The buzzer installed in 6 will sound, and the electric lock 6 on the hospital room side will be activated.
When the door 41 is shown to be unlocked and the handle 43 is pulled, the door 41 is opened. Then, the limit switch 81 on the hospital room side, which was in contact with the back surface of the door 41, is turned off.

On the other hand, even if the door 41 is opened in this way and the push button switch 62 on the patient room side is reset, even if the handle 53 is pulled in an attempt to open the door 51 on the front room side, the electric lock 7 on the front room side will be turned off. latch part 71 in the state
is engaged and the door 51 cannot be opened.Furthermore, press the front chamber side push button switch 72 to close the normally open contact 7.
Even if the door 51 is turned on, the limit switch 81 on the patient room side connected to it is in the off state, so the electric lock 7 on the front room side is not energized and remains locked, and the door 51 is not opened and the buzzer does not sound, so it is locked. This will prevent the handle 53 from being pulled unnecessarily.

The same applies even if the push button switch 62 on the patient's room side is pressed. Next, the door 41 on the side of the hospital room is closed in the same manner as the door 51 on the front room side described above.

Furthermore, by chance, the doors 41 on the patient room side and the front room side,
Push button switches 62, 72 to open 51
Even if pressed, each pushbutton switch 62,
72 are different circuits, normally closed contact 62
1,722, normally open contacts 622, 721, so neither circuit is energized,
Therefore, the electric locks 6 and 7 are also kept locked, and the door 4 is closed.
Prevent the opening of 1,51.

As described above, the doors 41 and 51 on the patient room side and the front room side of the inbox 4 are interlocked with each other.

Next, the interlock in the outbox 5 and the blinking of the germicidal lamps 9 and 91 will be described.

First, as mentioned above, unless the patient room side push button switch 62' is pressed, the electric lock 6' on the patient room side will not be energized. will not open.
When the pushbutton switch 62' on the patient's room side is pressed, the normally closed contact 621' is turned off, and the normally open contact 62' is turned off.
2' is turned on. As a result, the electric lock 6' on the patient room side, the limit switch 82' on the front room side, and the push button switch 7 on the front room side are connected in parallel with the shunt _R4 .
Since the normally closed contact 722' of 2' is in the on state, it is energized and the buzzer provided in the electric lock 6' on the patient room side sounds, indicating that the electric lock 6' on the patient room side is in the unlocked state, and the handle 43 is turned on. When the door 41 is pulled, the door 41 is opened.

Then, the indoor limit switch 81' that was in contact with the back surface of the door 41 is turned off, thereby cutting off the shunt _R5 , turning off the relay 10, and turning off the timer D as well.

In this way, with the door 41 open and the push button switch 62' on the patient room side reset, even if the handle 53 is pulled in an attempt to open the door 51 on the front room side, the electric lock 7 on the front room side will be turned off. In the state, the latch part 71
is engaged and the door 51 cannot be opened. In addition, push button switch 7 on the front side of outbox 5
Even if 2' is pressed to turn on the normally open contact 722', the relay 10 connected to it is in the OFF state, so the electric lock 7' on the front chamber side is not energized and remains locked.
The door 51 cannot be opened and the buzzer does not sound, indicating that it is locked, and the door 51 cannot be opened.
3 is never run over.

The same holds true even when the push button switch 6' on the patient's room side is pressed.

Next, when closing the door 41 on the side of the hospital room, even if the electric lock 6' on the side of the hospital room is in the closed state, the latch part 6
The door 41 is opened by the kicking action using the spring 1'.
is closed, and as a result, the back surface of the door 41 comes into contact with the limit switch 81' on the hospital room side, returning the limit switch 81' on the hospital room side to the on state, energizing the shunt _R5 , and turning on the relay 10. Also, timer D is turned on, and contact D ₁ of timer D is turned on.
is turned off, contact D ₂ is turned on, the germicidal lamps 9 and 91 are turned on, and the hour meter C starts to operate and starts counting the lighting time of the germicidal lamps 9 and 91. In this state, the shunt _R4 is not energized at all because the contact _D1 of the timer D is off, and the electric locks 6' and 7' remain locked in any case to prevent the doors 41 and 51 from opening. do.

Next, when a predetermined period of time (the time set in the timer) has elapsed with the germicidal lights 9, 91 on, the contact _D1 of the timer D is turned on, the contact _D2 is returned to the off state, and the germicidal lights 9, 91 are turned on. goes out and hour meter C stops. When the door 41 is opened and closed again, the germicidal lights 9 and 91 are turned on by the same operation as described above. In other words, germicidal lights 9 and 91 are outbox 5.
When the door 41 on the side of the hospital room is closed, the light is always turned on for a predetermined period of time.

Next, when opening the door 51 on the front chamber side, when the front chamber side push button switch 72' of the outbox 5 is pressed, the normally open contact 721' is turned on and the normally closed contact 722' is turned off. This causes shunt R ₄
The normally closed contacts 621' of the relay 10, the electric lock 7' on the front room side, and the push button switch 62' on the patient room side connected to the front room side push button switch 62' are energized because they are in the on state, and the electric lock 7' on the front room side is energized.
The buzzer installed in the front room side electric lock 7' sounds and
The door 51 is opened by indicating that it is in the unlocked state and pulling the handle 53 in this state. Then, the front chamber side limit switch 82' which was in contact with the back surface of the door 51 is turned off.

Next, even if the door 51 is opened as described above and the push button switch 72' on the front room side is reset, even if the handle 43 is pulled in an attempt to release the door 41 on the patient room side, the electric lock on the patient room side ' is in the off state, the latch 61 is engaged, and the door 41 cannot be opened.
Furthermore, even if the patient room side push button switch 62' is pressed to turn on the normally open contact 622, the front room side limit switch 82' connected to this is in the OFF state.
The electric lock 6' on the hospital room side is not energized and remains locked, the door 41 is not opened, and the buzzer does not sound, indicating that the door is locked, and the handle 43 is not pulled indiscriminately. On the other hand, the same thing happens even if the push button switch 72' on the front room side is pressed, or if you accidentally press the push button switches 62', 72' on the patient room side and the front room side at the same time and try to open the doors 41, 51. Also, each pushbutton switch 62', 7
2' are different circuits, normally closed contacts 62
1', 722', and normally open contacts 622', 721', none of the circuits are energized, and therefore the electric locks 6', 7' also remain locked,
Prevent doors 41, 51 from opening.

As described above, the present invention divides the pass box into an inbox dedicated to transporting items from the front room to the patient room and an outbox dedicated to transporting goods from the patient room to the front room. In addition, since each door is interlocked with each other, there is no risk of items accidentally falling onto the other side when placing the items in the box, and there is no risk of the items being dropped onto the other side while being carried in. When the door is opened, the contaminated air inside the hospital room will not inadvertently flow into the front room. In addition, there is a germicidal light inside the outbox that turns on automatically for a predetermined period of time when the outbox door is closed, and while the germicidal light is on, neither the patient room side nor the front room side doors of the outbox can be opened. Therefore, contaminated items (such as tableware, etc.) in the hospital room are completely sterilized, and there is no possibility that contaminated items will be accidentally carried out to the front room and become a source of infection.
