Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a forced hand-washing device for food factories, pharmaceutical factories, etc., which prevents people from entering or leaving the room without washing their hands.

(Conventional technology) Traditionally, before entering or leaving a factory where food products such as pharmaceuticals are manufactured, hands are rubbed with detergent or soap for a certain period of time as shown in Figure 3, then washed with water for a certain period of time, and then A forced hand-washing device has been developed that prevents electric locks on doors from being unlocked (turned off) until the specified hand-washing process is completed, such as by drying with a hair dryer and then sterilizing with alcohol.

In this case, there is no need to manually operate the cleaning liquid container, faucet valve, blower switch, etc., and tap water or hot air will automatically come out just by placing your hand near them.

Moreover, food handlers are instructed by public health centers to rub their hands with detergent or soap and then rinse under running water for at least 30 seconds, so the forced hand washing device described above does not have a sensor. The water continues to flow for at least 30 seconds after the sensor senses your hand, allowing you to wash your hands.

Therefore, if a conventional forced hand washing device is installed,
Sufficient hygiene management will be carried out when entering and exiting the room.

(Problems to be Solved by the Invention) However, conventional forced hand washing devices have the following problems.

Washing your hands with tap water for 30 seconds feels like a long time, so you may find it annoying to wash your hands and stop halfway through. Moreover, with conventional forced hand-washing devices, it is not known how much time should be left to wash hands after each hand-washing process has started, making the hand-washing time seem particularly long.
There were times when I stopped washing my hands in the middle. but,
With conventional forced hand-washing devices, once hand-washing has started and the water has been running for 30 seconds, it is possible to move on to the next hand-washing process. It did not result in forced hand washing as it should have.

Furthermore, since there is no means for determining whether or not the hand washing has actually been carried out, it is difficult to carry out forced hand washing.

(Object of the Invention) The object of the present invention is to solve the above-mentioned problems.In any hand-washing process, unless you hold out your hand and wash your hands for a predetermined period of time, you cannot move on to the next hand-washing process. If the interruption continues, you will have to start washing your hands all over again, and you will have no choice but to wash your hands by making sure that automatic doors and electric locks do not open unless all hand-washing steps have been completed reliably. The purpose of the present invention is to provide a forced hand washing device that prevents the use of forced hand washing.

(Means for Solving the Problems) The forced hand washing device according to claim 1 of the present invention, as shown in FIG.

If you stop the process halfway through, the door will not be unlocked or the auto door will open unless you start washing your hands again from the beginning, so you can force the user to wash their hands even more completely.

In the forced hand washing device according to claim 3 of the present invention,
Since the remaining time of each hand-washing step is displayed on the display sections 5a to 5d, the user can check the hand-washing time, making it easier to wash hands reliably for the predetermined time even in a hurry.

(Embodiment) FIGS. 1 and 2 show an embodiment of the forced hand washing device of the present invention. In these figures, A is the cleaning liquid discharge part, B is the massaging part, C is the water washing part, D is the drying part, E is the alcohol sterilization part, F is the operating part of the electric lock or automatic door, etc., and G is the prohibition circuit. .

In the forced hand washing device of the present invention, forced hand washing is performed as follows.

First, in the cleaning liquid adhesion part A, when a hand approaches the sensor part 1a, such as an infrared photoelectric sensor, installed near the cleaning liquid discharge port, the sensor part 1a
A senses the hand, and at the same time, the supply unit 2a is driven by a signal from the processing unit 3a such as a timer, and the cleaning liquid is discharged from the cleaning liquid tank 13 and attached to the hand. During this time, the cleaning liquid discharge time is accumulated in the processing unit 3a such as a timer, and when the time reaches a predetermined set time, the discharge is stopped.
A signal indicating that it is possible to proceed to the next massaging process is output from the processing section 3a.

Next, in the massaging section B, when the hand covered with the cleaning liquid is held out near the sensor section 1b, the sensor 1b senses the hand, and this is input to the AND circuit 11a. At the same time, the same AND circuit 11a
A clock signal is inputted from the clock signal generation circuit 10, and a clock signal outputted from the AND circuit 11a is inputted to the processing section 3b. As a result, the massaging time is accumulated in the processing section 3b, and when that time reaches a predetermined set time, a signal indicating that the transfer is possible is outputted from the processing section 3b, and this is the timer for the next washing section C. etc. is input to the processing unit 3c.

At the same time, every time a clock signal is input to the processing section 3b, the down counter of the processing section 3b is counted down, and the remaining time of the massaging process is displayed on the subtractive display section 5a.

In addition, if the accumulated time during the massaging does not reach the set time even after a predetermined time has elapsed, the hand washing device is automatically reset by a reset circuit 4a such as a reset timer. , so that you have to start washing your hands all over again from the beginning.

The set time can be set or changed to a desired value using a time setter 14a.

Further, the pilot lamp 15a is turned on at the same time as the scrubbing starts, and continues to be turned on until the same process is finished.

In the subsequent washing section C, when you put your hand under the faucet, the hand is detected by the sensor section 1c installed nearby, and the sensing signal is sent to the AND circuit 17.
is input. This sensing signal is also input to the AND circuit 11b, and at the same time the same AND circuit 11b
A clock signal is inputted from the clock signal generation circuit 10, and a clock signal outputted from the AND circuit 11b is inputted to a processing section 3c such as a timer. As a result, the washing time is accumulated in the processing section 3c, and at the same time, a signal is output from the processing section 3c each time a clock signal is input to the processing section 3c, and this signal is input to the AND circuit 17.
At this time, a signal is output from the AND circuit 17 to drive the electromagnetic valve drive circuit 16, the water pipe faucet is opened, and water comes out from the water supply section 2b.

During this time, the water washing time is accumulated in the processing section 3c, and when that time reaches a predetermined set time, the water flow is stopped, and the processing section 3c
A signal indicating that it is possible to proceed to the next drying step is output from c. This signal is interface 18
It is inputted to a processing section 3d such as a counter of the drying section D via the.

At the same time, every time a clock signal is input to the processing section 3c, the down counter of the processing section 3c is counted down, and the remaining time of the washing process is displayed on the subtractive display section 5b.

In addition, at this time, similarly to the above-mentioned massaging step,
If the accumulated time does not reach the set time even after a certain period of time has elapsed, the hand washing device is automatically reset by a reset circuit 4b such as a reset timer.

Further, the set time can be set or changed to a desired value using a time limit setting device 14b.

Also, at the same time as washing starts, pilot lamp 1
5b lights up and the same lamp 1 remains on until the same process is completed.
5b remains lit.

Next, in drying section D, when you bring your hand close to the air vent,
The hand is sensed by a sensor section 1d installed near the hand. The sensing signal is the AND circuit 21
is input to the AND circuit 19. At the same time, a clock signal is input from the clock signal generation circuit 22 to the AND circuit 21, and the clock signal output from the AND circuit 21 at this time is applied to the processing section 3d such as a timer.
is input. As a result, the drying time is accumulated in the processing section 3d, and at the same time, a signal is output from the processing section 3d each time a clock signal is input to the processing section 3d, and this signal is input to the AND circuit 19. At this time, a signal is output from the AND circuit 19 to drive the hot air supply section 2c, and hot air is blown from there.

During this time, each time a clock signal is input from the AND circuit 21 to the processing section 3d, the drying time is integrated in the processing section 3d, and when the time reaches a predetermined set time, the water flow is stopped and the drying time is integrated. A signal indicating that it is possible to proceed to the next drying step is output from the processing section 3d. This signal is input to the alcohol sterilization section E via the interface 20.

At the same time, every time a clock signal is input to the processing section 3d, the down counter of the processing section 3d is counted down, and the remaining time of the drying process is displayed on the subtractive display section 5c. At this time, as in the washing process, if the cumulative time does not reach the set time even after a certain period of time has elapsed, the reset circuit 4c such as a reset timer is activated.
The handwashing device is automatically reset by the button.

Further, the set time can be set to a desired value using a time limit setting device 14c.

Next, in the alcohol sterilization section E, when the hand approaches the alcohol spout, the hand is detected by the sensor section 1d installed nearby. The sensing signal is input to an AND circuit 24 and an AND circuit 25. At the same time, a clock signal is input from the clock signal generation circuit 26 to the AND circuit 24, and at this time,
A clock signal output from the AND circuit 24 is input to a processing section 3e such as a timer. As a result, the sterilization time is integrated in the processing section 3e, and at the same time, a signal is output from the processing section 3e each time a clock signal is input to the processing section 3e, and the signal is input to the AND circuit 25. At this time, a signal is output from the AND circuit 25 and the alcohol supply section 2
d is driven, and alcohol is pumped out from there.

During this time, each time a clock signal is input from the AND circuit 24 to the processing section 3e, the sterilization time is integrated in the processing section 3e, and when the time reaches a predetermined set time, the supply of alcohol is stopped and , a signal for unlocking the auto door is output from the processing unit 3e. This signal is inputted via the interface 27 to an operating unit F such as an electric lock or an automatic door.

At the same time, every time a clock signal is input to the processing section 3e, the down counter of the processing section 3e is counted down, and the remaining time of the sterilization process is displayed on the subtractive display section 5d. At this time, as in the sterilization process, if the cumulative time does not reach the set time, the hand washing device is automatically reset by a reset circuit 4d such as a reset timer. It is set as.

Further, the set time can be set or changed to a desired value using a time limit setting device 14d.

In addition, each of the above-mentioned sensor parts 1a to 1e is
It operates only while it is sensing a hand and outputs a sensing signal.

A prohibition circuit G is provided between the sensor sections 1a to 1e described above.
is provided. This prohibition circuit G is connected to the sensor section 1 of the cleaning liquid discharge section A in the reset state of the hand washing device.
When each process is completed, only the sensor section of the process immediately after it is activated. In this way, for example, even if you suddenly hold your hand to the faucet without applying cleaning liquid to your hand, no water will come out, and even if you put your hand into the dryer without washing with water after applying hand cleaning liquid, hot air will not blow out. It becomes like this. Therefore, unless the hand-washing process is performed according to a predetermined procedure, it is not possible to proceed to the next hand-washing process.

Incidentally, the number and procedure of the hand-washing steps described above may be other than those shown in the diagram, and there may be more or fewer hand-washing steps than those shown in the diagram. You can change it.

(Effects of the Invention) The forced hand washing device of the present invention has the following various effects.

Since the electric lock and automatic door will not be opened unless each hand washing process is carried out within the specified time according to a predetermined procedure, compulsory hand washing can be ensured.

If hand-washing is interrupted midway through, the hand-washing device is reset and the hand-washing must be restarted from the beginning, resulting in more thorough hand-washing.

Since the remaining time for each hand-washing step is displayed, the hand-washing process is not interrupted midway and is more likely to be carried out to the end.

If a prohibition circuit G is provided between the sensor parts 1a to 1e so that when each process is completed, only the sensor part of the process immediately after it is activated, the next one will not be activated unless the hand washing is performed according to the predetermined procedure. Since it is not possible to proceed to the hand-washing process, hand-washing is performed more thoroughly.
