Abstract

PURPOSE:To arrange forcible hand washing with the completion of all the hand washing processes as a prerequisite to open an automatic door, an electric lock, etc., by providing each hand washing process with a sensor section, a supply section for supplying water and hot air only after the presence of a human hand is detected, and a processing section including a timer for calculating the sum of the hand washing time. CONSTITUTION:In a washing liquid application section A, access of a hand to a sensor section 1a such as a photoelectric sensor by means of infrared rays and attached to the vicinity of a washing liquid outlet is detected with the sensor section 1a. At the same time, a supply section 2a is driven with a signal from a processing section 3a such as a timer to dispense washing liquid from a washing liquid tank and the liquid is applied to the hand. In the meantime, the cumulative time of washing liquid discharge is calculated at the processing section 3a such as a timer, etc. When the cumulative time reaches a predetermined value, the discharge is stopped, a signal is issued from the processing section 3a so that the next process of rub washing may be followed, and the process moves on to the next.

Description

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

(Conventional technology) Traditionally, in food and pharmaceutical factories, before entering and exiting,
As shown in Figure 3, if you do not complete the prescribed hand washing process by applying washing liquid or soap, massaging your hands for a certain period of time, then washing them with water for a certain period of time, drying them with a hair dryer, and then sterilizing them with alcohol, the door will open. A forced hand-washing device has been developed that prevents electronic locks from being unlocked (turned off).

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 wash their hands with detergent or soap and then rinse under running water for at least 30 seconds, so the above-mentioned forced hand-washing device does not allow the sensor to detect the hands. at least 30 years after
The water continues to run for a few seconds, allowing you to wash your hands.

Therefore, if a conventional forced hand-washing device is installed, hygiene control when entering and exiting a room will be sufficiently performed.

(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 long the hand-washing process should continue after the start of each hand-washing process, making the hand-washing time feel especially long and causing the user to stop washing his hands mid-way. However, with conventional forced hand-washing devices, once hand-washing has started, water is
As long as you run the water for 0 seconds, you can move on to the next hand-washing process, so even if you stop washing your hands midway through, it still means you've washed your hands, so it wasn't forced hand-washing as it should have been.

■． In addition, there is no means for determining whether or not the hand washing has actually been carried out, making it 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.

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 every time a clock signal is input to the processing section 3c, and the signal is outputted from the processing section 3c.
The signal is input to the D 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 washing time is accumulated in the processing section 3c, and when the time reaches a predetermined setting time, the water flow is stopped and a signal indicating that it is possible to proceed to the next drying process is output from the processing section 3c. be done. This signal is input to a processing section 3d such as a counter in the drying section D via the interface 18.

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 this case, as in the massaging step, if the cumulative time does not reach the set time even after a certain amount 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 is set by the time limit setting device 14b. It is possible to set or change the desired value.

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

Next, in the drying section D, when the hand approaches the air outlet, the hand is detected by the sensor section 1d installed nearby. The sensing signal is input to the AND circuit 2l and the AND circuit 19. At the same time, a clock signal is input from the clock signal generation circuit 22 to the AND circuit 2l, and at this time
A clock signal output from the circuit 2l is manually input to a processing section 3d such as a timer. As a result, the drying time is accumulated in the processing section 3d, and at the same time, a signal is outputted from the processing section 3d each time a clock signal is input to the processing section 3d, and the signal is inputted 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 2l to the processing section 3d, the drying time is accumulated in the same processing section 3d, and when the time reaches a predetermined set time, the water flow is stopped. At the same time, 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, each 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 well as in the water washing process, if the cumulative 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 4C such as a reset timer. be.

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

At this time, a clock signal is manually inputted from the clock signal generation circuit 26, and the clock signal output from the AND circuit 24 at this time is inputted to the processing section 3e such as a timer. As a result, the sterilization time is accumulated in the processing section 3e, and at the same time, a signal is outputted from the processing section 3e each time a clock signal is inputted to the processing section 3e, and the signal is outputted to the AND circuit 25.
is man-powered. At this time, a signal is output from the AND circuit 25 to drive the alcohol supply section 2d, and alcohol is sent out from there.

During this time, every 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 , same processing section 3
A signal for unlocking the auto door is output from e. 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 step, if the cumulative time does not reach the set time even after a certain period of time has elapsed, the reset circuit 4 such as a reset timer is activated.
The handwashing device is automatically reset by d.

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

Each of the above-mentioned sensor sections 1a to 1e is configured to operate only while sensing the hand and output a sensing signal.

A prohibition circuit G is provided between the sensor sections 1a to 1le described above. This prohibition circuit G operates only the sensor section Ia of the cleaning liquid discharge section A when the hand washing device is reset, and when each process is completed, only the sensor section of the process immediately after it operates. In this way, for example, if you suddenly put your hand into the faucet without applying cleaning liquid to your hand, water will still come out, or even if you put your hand in cleaning liquid and then put your hand into the dryer without washing with water, hot air will still blow out. It will not be done. 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 steps of the hand-washing steps described above may be other than those shown in the diagram, and there may be more or less hand-washing steps than those shown in the diagram, or there may be times before and after the hand-washing steps. may be changed.

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

■． The electric lock and automatic door will not be opened unless each hand-washing process is performed within the specified time according to a predetermined procedure, so it is possible to ensure that forced hand-washing is complied with.

■． If you interrupt handwashing midway through, the handwashing device will be reset and you will have to start washing your hands all over again, making forced handwashing even more thorough.

■． 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 units 1a to 1le so that when each process is completed, only the sensor unit for the process immediately after it is activated, the next process will be disabled unless hand washing is performed according to the predetermined procedure. Since the child cannot move on to the hand-washing process, the hand-washing process is more thorough.
