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

In FIG. 1, reference numeral 1 denotes a door opening / closing system. The door opening and closing system 1 includes a door 3 and a door opening and closing device 9, and further includes a hand washing device 5 and a footwear washing device 7 outside the door 3. The room which can enter by opening the door 3 corresponds to, for example, a non-polluted area such as a kitchen.

A door opening / closing device 9 is connected to the door 3, and the door 3 is configured to open in the direction of arrow A. A control device 11 is connected to the door opening and closing device 9, and the opening and closing of the door 3 is controlled by the control device 11.

As shown in FIG. 2, the hand washing apparatus 5 has a washing case 13 in which a washing chamber 15 is formed. Side wall 1 of this cleaning case 13
An infrared sensor 17 is provided at 3a, and the finger inserted into the cleaning chamber 15 is detected by the infrared sensor 17. A cleaning water jet nozzle 19 is provided on the upper wall 13b of the cleaning case 13. A washing water pipe 21 is connected to the washing water jet nozzle 19, and the washing water pipe 2
1, a water supply valve 23 is connected.
Is connected to a water pipe 25. The washing water jet nozzle 19, the washing water pipe 21, and the water supply valve 23 constitute a washing water jetting device 27. This infrared sensor 17
The water supply valve 23 is connected to the control device 11 and controlled by the control device 11.

As shown in FIG.
An immersion tank 29 and a sheet sensor 31 laid under the immersion tank 29 are provided. The interior of the immersion tank 29 is filled with a sterilizing solution, and the sheet sensor 31 is connected to the control device 11 described above.
It is connected to the.

The control device 11 of the door opening / closing system 1 includes:
As shown in FIG. 4, an infrared sensor 17, a sheet sensor 31, and a timer 33 are connected to input ports by control signal lines 35a to 35a.
5c, and the output port is connected to the door opening / closing device 9 and the water supply valve 23 via control signal lines 35d and 35e.

Next, the operation of the door opening and closing system 1 will be described with reference to FIG.

When a finger is inserted into the washing room 15 of the finger washing device 5, the control device 11
When the infrared rays generated from the fingers are detected for a predetermined time (several seconds), it is detected that the fingers are inserted into the cleaning room 15 (S1).

When finger insertion is detected by the control device 11, the control device 11 sends a control signal to the timer 33 via the control signal line 35c and to the water supply valve 23 via the control signal line 35e (S2). When the control signal is
When the cleaning water is sent to the cleaning water pipe 2, the valve opens.
1 and is ejected from the washing water ejection nozzle 19. When the control signal is sent to the timer 33, the timer 33 counts the flushing time of the washing water.

When the counted ejection time (count value) reaches a predetermined time (S3), the control device 11 sends a control signal to the water supply valve 23 via a control signal line 35e.
At the same time as closing the valve, the count value is sent to the timer 33 and reset (S4). The above-mentioned predetermined time is 3 seconds in the present embodiment.

When the hand washing is completed, the control device 11
The footwear of the user is immersed in the immersion tank 2 by the sheet sensor 31.
It is presumed that it is soaked in the sterilizing solution of No. 9. That is, the seat sensor 31 converts the weight (pressure) of the user riding on the seat sensor 31 into a current by the piezoelectric effect, and detects whether or not the current is generated.

When it is estimated by the control device 11 that the footwear is immersed in the sterilizing solution in the immersion tank 29, the control device 1
1 sends a control signal to the timer 33 via the control signal line 35c (S5). When the control signal is sent to the timer 33, the timer 33 counts the time during which the footwear is immersed in the sterilizing solution in the immersion tank 29.

When the counted time (count value) reaches a predetermined time (S6), the control device 11 sends a control signal to the door opening / closing device 9 via the control signal line 35d to open the door, The signal is sent to the timer 33 via the control signal line 35c to reset the count value (S7).

As another embodiment, a clothes washing device (not shown) is provided outside the door 3 in addition to the hand washing device and the footwear washing device, and a hand washing operation by the hand washing device and a footwear washing operation by the footwear washing device are provided. The door 3 may be opened in conjunction with the operation and the end of all the clothes washing operations by the clothes washing apparatus.

Next, another embodiment will be described with reference to FIG.

The washing chamber of the washing case 13 of the hand washing apparatus 5 is divided into two parts by the partition plate 37 so as to fit the left and right fingers, and each of the washing chambers 15a and 15b has an infrared sensor 17a.
17b and cleaning water jet nozzles 19a and 19b are provided.

Then, both fingers are simultaneously in the cleaning chamber 15.
The control device 11 is configured not to detect the insertion of a finger unless it is inserted into a and 15b.

The operation of the door opening and closing system 1 according to this embodiment will be described.

The control device 11 is configured such that one finger is
a, the other finger is simultaneously inserted into the cleaning chamber 15b, the infrared sensor 17a detects the finger inserted into the cleaning chamber 15a, and the infrared sensor 17b detects the finger inserted into the cleaning chamber 15b. This detects that both fingers have been inserted into the cleaning chambers 15a and 15b.

When the insertion of the finger is detected, the above-described finger washing operation is performed.

That is, if the insertion of both fingers is not detected, the operation of the above-mentioned finger washing device 5 is not performed. For this reason, the user must insert both fingers at the same time, and both fingers can be reliably washed.
