[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device such as a hand-washing device used for cleaning the fingers of personnel engaged in medical care, food manufacturing, hospitality, etc.

[0002]

2. Description of the Related Art Due to its nature, there are business fields in which cleanliness is strongly required, such as the medical and food manufacturing industries. In such a business field, in particular, cleanliness of fingers touching a patient or a food product to be manufactured is required. Therefore, in a facility that performs such work, a hand washing device is provided, or a washing room or the like provided with the washing device is provided. Such a cleaning device includes a water spouting device that discharges cleaning water from a nozzle, a soap liquid discharging device that discharges soap liquid from the nozzle, and the like. Such various devices are arranged relatively close to each other, and are configured to be convenient for a series of operations for washing fingers.

In order to wash the fingers using this washing apparatus, a plurality of individual works described below are sequentially performed. First, perform pre-washing by discharging water to wet the fingers. Then eject the soap solution,
Rub both hands together and wash your hands with soap. When the washing with the soap solution is sufficiently performed, water is discharged again to wash the fingers and remove the soap content. Next, the fingers are dried using paper, cloth, or the like, or using warm air. next,
Disinfect your fingers with an antiseptic solution.

When this cleaning device is provided in a cleaning room dedicated to cleaning, the door for entering and exiting is an automatic door,
When moving in and out of the washing room, it may be necessary to prevent the fingers from touching the door.

Further, the following technique may be adopted in the conventional cleaning device. That is, whether or not each of the individual works required for cleaning the fingers has been sufficiently performed is determined based on the elapsed time of each work or the like. When it is determined that the fingers have not been sufficiently washed, the door of the washing chamber is closed and closed until it is determined that the fingers have been sufficiently washed. As a result, careless contamination of fingers is prevented, and contamination of patients and the like in medical treatment with bacteria or the like, or contamination of manufactured foods with bacteria or the like is prevented.

In the conventional cleaning apparatus, each of the above-mentioned individual works required for cleaning is performed in either the manual mode or the forced mode. In the manual mode cleaning device, operation buttons are provided in the vicinity of nozzles for discharging various fluids such as water for cleaning, and water is discharged for a certain time by operating each operation button. . Therefore, it is possible to start from any individual work and end with any individual work. Further, one individual work can be repeated any number of times. On the other hand, in this manual mode cleaning device, there are problems that omission of individual work, shortage of work time for individual work, and the like are likely to occur, and that cleaning of fingers is insufficient.

On the other hand, in the forced mode, the cleaning device automatically executes ejection of each fluid in accordance with the above-described procedure in finger cleaning, without being based on the operation of the user. That is, the cleaning device discharges water for pre-cleaning for a predetermined time and discharges soap liquid for a predetermined time. Next, water is again discharged for a predetermined time. The operator
According to such a sequence of operation of the cleaning device, a hand is extended under each nozzle. As a result, the fingers are washed.

[0008]

In the conventional forced mode cleaning device, the discharge of each fluid used for each individual work is performed in a predetermined order for a predetermined discharge time. Therefore, depending on the degree of stains on the fingers, there are cases where the washing of the fingers is insufficient in the individual work for the predetermined time. Conventionally, in such a case, since the individual work is forcibly progressed, there is a problem that it is difficult to re-execute the already completed individual work in an intermediate stage where all are not completed. ing.

Further, in the conventional cleaning apparatus, each individual work is executed in a predetermined order for a predetermined operation time. Therefore, the fluid used for the next individual work to be performed is discharged in a state where the object to be cleaned is not discharged below the corresponding nozzle. That is, there is a problem that the discharged fluid is wastefully consumed until the object to be cleaned is placed under the nozzle.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a cleaning apparatus capable of cleaning an object to be cleaned with high cleanliness.

[0011]

A cleaning apparatus according to the present invention is provided with a plurality of nozzles for ejecting a plurality of kinds of fluids used for cleaning an object to be cleaned, and a nozzle provided in the vicinity of each nozzle. A plurality of detection means for detecting the respective objects to be cleaned and the nozzles to which the objects to be cleaned should approach .
And guide means for outputting guidance information indicating the order of use, to detect a state which has been shown one nozzle by the guide means, and detects the detection operation of the cleaning object by the detection means corresponding to the nozzle , Ejecting fluid from the nozzle ,
Also, the one nozzle is not shown by the guiding means.
In this state, the detection means corresponding to the nozzle is used to wash
Next, the object to be cleaned comes into contact until the non-detection operation of the object is detected.
And a control means for controlling so as to stop the guidance to the nozzle to be approached, whereby the above object is achieved.

In the cleaning apparatus of the present invention, the guide means is provided near each of the nozzles, and each guide means outputs the guide information to indicate the order of the nozzles to which the object to be cleaned approaches. The above object is achieved thereby.

[0013]

When the object to be cleaned is to be cleaned using the cleaning apparatus of the present invention, the object to be cleaned is brought close to any one of the plurality of detecting means. When the detection means detects the object to be cleaned,
The control means detects the detection operation by the detection means. Further, when the cleaning with the fluid from one nozzle is performed so as to satisfy a predetermined condition, the guiding means outputs the guiding information indicating the order of the nozzles to which the object to be cleaned approaches. That is, the guiding means guides the object to be cleaned by the fluid from one nozzle indicated by the guiding means. The control means detects the state in which one nozzle is shown by the guide means, detects the detection operation of the object to be cleaned by the detection means corresponding to the nozzle, and discharges the fluid from the nozzle.

Therefore, when the cleaning of the object to be cleaned with the fluid from one nozzle is not performed so as to satisfy the predetermined condition, the guiding means does not guide the next individual work. Therefore, one individual work is continuously performed until the guiding means guides to the next individual work. That is, the guide means does not guide the nozzle.
In this condition, the detection means corresponding to this nozzle
The object to be cleaned next approaches until the non-detection operation of the object is detected.
Control to stop the induction to the nozzle to be
Become. As a result, individual work can be performed to adequately clean the object to be cleaned.
The required amount of cleaning for a predetermined period, or the degree to which your fingers are dirty
Depending on the degree, it is possible to perform cleaning for more than a predetermined period
In addition, the object to be cleaned appears under the corresponding nozzle.
Fluid from the next nozzle to be used
It is also possible to prevent the discharge of fluid, and useless fluid
There is no need to discharge from. Therefore,
The object to be cleaned can be cleaned with a high degree of cleanliness without wastefully discharging the fluid .

When one individual work is performed for a predetermined period, the user is guided to the next individual work by the guiding means. In such a guided state, the fluid used for cleaning is discharged from the nozzle when the object to be cleaned is detected by the detection means belonging to the next individual work. Therefore, it is possible to prevent the fluid used for the next individual work to be ejected in a state where the object to be cleaned is not ejected under the corresponding nozzle, and it is possible to conserve the resources of the ejected fluid. . In addition, since the user is not forced to the next individual work by the discharge of the water or the like, the individual work should be performed for a period that is determined by the user to be longer than the predetermined period in each individual work. It is possible to significantly improve the cleanliness of fingers.

When a plurality of nozzles for respectively ejecting the plurality of kinds of fluids and an apparatus for ejecting the plurality of kinds of fluids from the respective nozzles are integrally configured as the cleaning apparatus of the present invention, each of the plurality of kinds of fluids is The work of the user who performs the cleaning operation is simplified as compared with the case where the devices are combined.

(B) Operation of Cleaning Device 1 FIG. 6 is a time chart for explaining the operation of the cleaning device 1 in the normal mode, and FIGS. 7 to 10 explain the operation of the cleaning device 1 in the normal mode. It is a flowchart to do. An automatic door is installed in the cleaning room where the cleaning device 1 is installed, and opening and closing of the door for entering and exiting the room,
The detection operation is performed by a detection element such as an infrared sensor as an example of being installed outdoors and indoors. When a person stands in front of the door to enter the washing room, the sensor outside the room detects the person and opens the door. When a user enters the cleaning chamber, the cleaning device 1 detects the sensor in the chamber to the automatic door control device 77 in order to prevent the user from leaving the room with insufficient cleaning of fingers. Disables capturing of output. That is, even if a person is detected by the sensor in the room, the driving of the door driving motor 78 is prohibited. In the cleaning device 1, when the operation switch 65 is operated to turn on the power, the control circuit 47 determines in step a1 in FIG. 7 whether the operation mode of the cleaning device 1 is the normal mode or the induction mode. To judge.

(A) Normal mode (1) Selection of each operation If the operation mode of the cleaning apparatus 1 is set to the normal operation mode by the mode selector switch 39, step a
The determination of 1 is affirmative, and the detection of the user's finger by the water sensor 9 is determined in step a2. If the determination in step a1 is negative, the process proceeds to step b1 shown in FIG. 12, and the guidance mode described later is started. If the determination is affirmative in step a2, the process shown in FIG.
The process moves to step a20 shown in, and the process related to the water discharge operation is performed. Next, the processing for confirming the amount of the disinfecting liquid in step a3 is performed. Details of the processing in step a3 are shown in FIG. Then, in step a4, the detection of the finger by the antiseptic solution sensor 11 is determined. If the determination in step a4 is affirmative, the process proceeds to step a37 shown in FIG. 10, and the process related to spraying the disinfectant solution is performed.

(2) Processing Related to Discharge of Soap Liquid If the determination in step a4 is negative, it is detected in step a5 that the amount of soap liquid in the tank 23 by the float switch 25 is relatively small, that is, the float. It is determined that the switch 25 is on. As shown in FIG. 6 (7), when the float switch 25 is turned on at time t1, the determination in step 5 becomes affirmative, and step a6
At this time, after the float switch 25 is turned on, every time the soap liquid discharge pump 27 is driven, a counting operation is performed in which the driving number n1 is incremented by +1.
It is determined whether the counting result n1 has reached a predetermined numerical value N1. This numerical value N1 is calculated from the discharge amount of the soap liquid once and the capacity of the tank 23. If this determination is negative, in step a7, as shown in FIG. 6 (12), at time t1, the lamp 18 that prompts the supplement of the soap liquid blinks. Then, the process proceeds to step a8. If the determination at step a6 is affirmative, then at step a9, as shown in FIG.
At step a5, the lamp 18 is turned on.
Return to.

That is, when the float switch 25 detects the decrease in the soap solution, the lamp 18 blinks, and this blinking causes the user to have a relatively small amount of the soap solution and it is necessary to replenish it. To inform. Furthermore, when the driving number n1 of the discharge pump 27 reaches the numerical value N1, it means that the soap liquid is extremely small and needs to be replenished promptly. To inform. In such a state in which the soap solution needs to be replenished, even if the soap solution sensor 10 detects a finger at time t3 as shown in FIG. 6A, the control circuit 47 causes the discharge pump 27 to operate. Do not drive.

On the other hand, if the determination in step a5 is negative, the process proceeds to step a10. Such a judgment is established when the soap solution is sufficiently left in the tank 23 or immediately after the tank solution is replenished with the soap solution. In such a case, step a10
At time t4, the lamp 18 is turned off as shown in FIG. 6 (12), and the driving frequency n1 is cleared to 0 as an example at step a11. In step a8, it is judged whether or not the soap liquid sensor 10 is in the ON state in which the finger of the user is detected. If this determination is negative, the process returns to step a2.

As shown in FIG. 6 (1), when the soap liquid sensor 10 detects a finger at time t5, the determination at step a8 becomes affirmative and the on-delay timer 66 is started at step a12. It Here, FIG.
(2) As shown in (3) and (9) of the same figure, the signals from the sensors 9 to 11 of the cleaning apparatus 1 are prioritized by the signal from the one that detects the finger first. Thereafter, the signal from the sensor that detects the finger is canceled without being processed by the control circuit 47.

At step a13, it is judged whether or not the on-delay timer 66 has timed a predetermined time limit T1. If this judgment is negative, the process is step a.
Return to 2. The on-delay timer 66 is used for the cleaning device 1
It is used to prevent unnecessary operation of. The unnecessary operation is that the soap solution sensor 10 performs an instantaneous detection operation due to movement or mischief of a small creature, and thereby the soap solution is discharged from the nozzle 7. If the determination at step a13 is affirmative, at step a14, the elapsed timer 55 for measuring the soap liquid discharge time T2 is started.

In step a15, as shown in FIG. 6 (9), at time t6, the discharge pump 27 is started and the soap liquid is discharged from the nozzle 7. Step a16
At this time, it is judged whether or not the timer 67 has timed the time limit T2, and the discharge pump 27 is driven until the time measurement of the time limit T2. At step a17, as shown in FIG.
As shown in (9), at time t7, the pump 27 is stopped. That is, the discharge pump 27 is activated when the soap liquid sensor 10 detects a finger for longer than the time limit T2, and the discharge pump 27 is not activated when the detection time is shorter than the time limit T2. After that, even if the soap liquid sensor 10 no longer detects the finger, the soap liquid discharging operation is continued.

Then, in step a18, it is determined whether or not the soap liquid sensor 10 has detected the user's finger. If the soap liquid sensor 10 detects the user's finger, the pump 27 remains stopped in step a17, and if the finger is not detected, the process returns to step a2.

The determination in step a18 is affirmative in the following cases as an example. That is, when the finger detected by the soap liquid sensor 10 in step a8 remains in the detection range of the soap liquid sensor 10 even when the discharge pump 27 is stopped, or the soap liquid sensor 10 is detected.
This is the case, for example, when the finger detected by is once removed from the detection range of the sensor 10 and then inserted again into the detection range of the soap solution sensor 10. When the operation of the pump 27 is stopped for the time limit T2, the discharge pump 27 is prevented from immediately restarting its operation unless water or disinfectant liquid is discharged or sprayed from the other nozzles 6 and 8. .

(3) Processing relating to water discharge As shown in FIG. 6 (2), at time t8, when the water sensor 9 detects a finger, the determination at step a2 becomes affirmative, and the processing shown in FIG. The process moves to step a20 of the flowchart shown in. At step a20, as shown in FIG.
As shown in (0), at time t8, the on-delay timer 66 starts measuring a predetermined time limit T3. In step a21, the on-delay timer 66
However, it is determined whether or not the time limit time T3 has been measured, and the on-delay timer 66 measures the time until the time limit T3 elapses. The on-delay timer 66 is also used to prevent the unnecessary operation of the water sensor 9 as described above.

The on-delay timer 66 sets the time limit T
When 3 is measured, in step a22, the upper limit timer 68 that measures the upper limit value T4 of the water discharge time starts counting. In step a23, the solenoid valve 30 is switched to the open state, and in step a24, it is determined whether or not the water sensor 9 has detected a finger. If this judgment is affirmative, in step a25, the discharge of water is continued until the upper limit timer 68 measures the time limit T4. If the determination in step a25 is affirmative, step a26
At, the off-delay timer 69 used when the water discharge is stopped is driven, and at step a27, it is determined whether or not the off-delay timer 69 has counted the time limit T5. If this judgment is negative, the processing returns to step a24. Further, as shown in FIG. 6B, when the water sensor 9 no longer detects the finger at the time t9, the determination at step a24 becomes negative. At this time, the process proceeds to step a26, drives the off-delay timer 69, and waits until the time limit T5 is counted in step a27.

That is, water is discharged from the nozzle 6 for a period during which the water sensor 9 is detecting a finger or for a short period of the time limit T4. Further, when the state in which the water sensor 9 does not detect the finger continues for the period of the time limit T5, as shown in FIG.
In step a28, the solenoid valve 30 is switched to the closed state. Accordingly, even if it is intermittent that the water sensor 9 momentarily stops detecting the finger due to the movement of the finger during hand washing, the situation in which the discharge of water from the nozzle 6 is intermittent is prevented, and the finger is kept This prevents a situation in which the discharge of water from the nozzle 6 suddenly stops when the water is removed from the detection range of the water sensor 9.

In step a29, the water sensor 9 is used.
Determine whether is on. If the determination is negative, the process returns to step a2, and if the determination is positive, the closed state of the solenoid valve 30 is continued in step a28.

The determination in step a29 is positive in the following cases as an example. That is, the finger detected by the water liquid sensor 9 in step a24 remains in the detection range of the water sensor 9 even if the solenoid valve 30 is closed, or the finger detected by the water sensor 9 is detected. For example, when the removed fingers are once removed from the detection range of the water sensor 9 and then inserted again into the detection range of the water sensor 9. When the open state of the solenoid valve 30 for the time limit T4 is switched to the closed state, water is discharged from the nozzle 6 unless the soap liquid or the disinfectant liquid is discharged or sprayed from the other nozzles 7 and 8. Immediate ejection is prevented.

(4) Processing relating to spraying of disinfecting liquid The details of the disinfecting liquid amount confirmation processing in step a3 are shown in FIG. In FIG. 9, step a31, whether the float switch 26 in the tank 24 of the disinfectant solution has detected that the amount of the disinfectant solution in the tank 24 is relatively small,
That is, it is determined whether the float switch 26 is turned on.
As shown in FIG. 6 (8), when the float switch 26 is turned on at time t11, step a31
When the spray switch 29 for disinfectant is driven after the float switch 26 is turned on in step a32, a counting operation is performed in which the driving frequency n2 is incremented by +1. The counting result n2 is
It is determined whether or not a predetermined numerical value N2 has been reached.
This numerical value N2 is calculated from the spray amount of the antiseptic solution once and the capacity of the tank 24.

If the determination at step a32 is negative, at step a33, the lamp 22 for urging the supplement of the disinfectant solution blinks as shown in FIG. 6 (13). Then, the process proceeds to step a4 in FIG. If the determination at step a32 is affirmative, at step a34, as shown in FIG.
The lamp 22 is turned on as shown in (13), and the process returns to step a31.

That is, when the float switch 26 detects the decrease of the disinfectant solution in the tank 24, the lamp 2
2 flashes to inform the user that the disinfectant solution is relatively small and needs to be replenished. Further, when the driving number n2 of the spray pump 29 reaches the numerical value N2, the user is informed that the disinfectant solution in the tank 24 is extremely small and needs to be replenished immediately. .

On the other hand, if the determination in step a31 is negative, the process proceeds to step a35. Such a judgment is established when the disinfectant solution is sufficiently left in the tank 24 or immediately after the disinfectant solution is replenished in the tank 24. In such a case, step a35
In step a36, the lamp 22 is turned off, and in step a36, the driving number n2 is cleared to 0, for example.

As shown in FIG. 6 (3), at time t12, when the disinfectant solution sensor 11 detects a finger, the determination at step a4 becomes affirmative, and the process proceeds to step a37 of the flowchart shown in FIG. Move. At step a37, as shown in FIG. 6 (11), the on-delay timer 66 starts counting a predetermined time limit T6. In step a38, the on-delay timer 66 determines whether or not the time limit time T6 has been counted, and the on-delay timer 66 counts until the time limit T6 elapses. This on-delay timer 66 is also used to prevent the disinfectant solution sensor 11 from causing the unnecessary operation as described above.

The on-delay timer 66 sets the time limit T
When 6 is timed, in step a39, as shown in FIG.
At time t13, the upper limit timer 70 that measures the upper limit value T7 of the spray time of the disinfecting solution starts counting at time t13. In step a40, as shown in FIG. 6 (11), the spray pump 29 is driven, and in step a41, it is determined whether or not the disinfectant solution sensor 11 has detected the user's finger. If this judgment is affirmative, step a
At 42, it is judged whether the time limit time T7 is counted by the upper limit timer 70, and if negative, the process returns to step a41 to continue spraying the disinfecting solution. When the determination in step a42 becomes affirmative, in step a43, the spray pump 29 is stopped as shown in FIG. 6 (11). Even when the determination in step a41 is negative, the process proceeds to step a43.

In step a44, it is determined whether the disinfectant solution sensor 11 has detected the user's finger.
If this determination is affirmative, the process returns to step a43 to continue the stopped state of the spray pump 29. Step a
If the determination in 44 is negative, the process returns to step a2 of FIG. 7 through step a45.

At step a45, a door opening permission signal is output to the automatic door control device 77. Therefore,
When the approach of a person to the door is detected by an infrared sensor or the like in the room, the control device 77 drives the motor 78 based on the detection signal from the infrared sensor to open the door. If each individual work is insufficient, the operation of the cleaning apparatus 1 does not reach the step a49. Therefore, the door is not opened even if a person in the washing room approaches the door and is detected by the sensor in the room.

The determination in step a44 is positive in the following cases as an example. That is, when the finger detected by the disinfectant solution sensor 11 in step a4 remains in the detection range of the disinfectant solution sensor 11 after the spray pump 29 is stopped, or when the disinfectant solution sensor 11 is detected.
This is the case, for example, when the finger detected by is once removed from the detection range of the antiseptic solution sensor 11 and then inserted again into the detection range of the antiseptic solution sensor 11. When the operation of the spray pump 29 is stopped for the time limit T7, the spray pump 29 is prevented from immediately restarting operation unless water or soap solution is discharged from the other nozzles 6 and 7.

(5) Test Operation The cleaning apparatus 1 can test the discharge state or spray state of each fluid from each nozzle 6-8. This test is immediately executed by operating the test switches 36 to 38 regardless of whether the operation mode of the cleaning apparatus 1 is the normal mode or the guide mode described later.

As shown in FIG. 6 (4), FIG. 6 (5), and (6), the test switches 36 to 38 for soap liquid, water, and disinfectant liquid are respectively set at times t 15, t 16, and t 1.
7 is operated, as shown in FIGS. 6 (9), (10) and (11), each of the test switches 36-3.
The discharge pump 27, the electromagnetic valve 30, and the spray pump 29 operate for the period in which the nozzle 8 is operated, and soap liquid, water, and a disinfectant liquid are discharged or sprayed from the nozzles 6 to 8.

(B) First induction mode (1) Pre-cleaning process FIG. 11 is a time chart showing the operation of the cleaning apparatus 1 in the first induction mode, and FIGS. It is a flow chart which shows an example of operation of 1 guidance mode, respectively. If the operation mode of the cleaning apparatus 1 is set to the first induction mode by the mode changeover switches 39 and 40, the determination at step a1 in FIG. 7 becomes negative, and the process proceeds to step b1 in FIG. Step b1
At time t21, as shown in FIG. 11 (1), the guide lamp 15 for guiding the user to perform pre-washing blinks. In step b2, the water sensor 9 corresponding to the water nozzle 6 waits for detection of the user's finger. In step b2, FIG. 11 (7)
When a finger is detected at time t22, the on-delay timer 66 is operated at step b3.
Starts the time measurement of a predetermined time limit T13. In step b4, the on-delay timer 66 determines whether or not the time limit time T13 has been counted, and the time limit time T1
The on-delay timer 66 keeps time until 3 has elapsed. The on-delay timer 66 is used to prevent unnecessary operation of the water sensor 9.

The on-delay timer 66 sets the time limit T
When 13 is measured, in step b5, the upper limit timer 68 that measures the upper limit value T14 of the water discharge time starts counting. At step b6, as shown in FIG. 11 (13), at time t23, the solenoid valve 30 is switched to the open state, and at step b7, it is judged whether or not the water sensor 9 detects a finger. To do. If this determination is affirmative, in step b8, the discharge of water is continued until the upper limit timer 68 measures the time limit T14.

If the determination in step b8 is affirmative, in step b9, the off-delay timer 69 used when stopping the discharge of water is driven, and step b10
At this time, it is determined whether the off-delay timer 69 has timed the time limit T15. If this judgment is negative, the processing returns to step b7. If the determination in step b7 is negative, the process proceeds to step b9, the off-delay timer 69 is driven, and in step b10, the time limit T15 is waited for. That is, the time limit T
If the water sensor 9 no longer detects the finger even within the period of 15, and if the water sensor 9 remains in the state of not detecting the finger for the period of the time limit T15, the solenoid valve in step b11. 30 is switched to the valve closed state, and the discharge of water is stopped.

The off-delay timer 69 is used for the following purposes. That is, even if it is intermittent that the water sensor 9 momentarily stops detecting the finger due to the movement of the finger during hand washing, the situation in which the discharge of water from the nozzle 6 is intermittent is prevented, and the finger is kept wet. This prevents a situation in which the discharge of water from the nozzle 6 suddenly stops when it is out of the detection range of the sensor 9 for water.

In step b12, the induction lamp 1
5 is turned off. In step b13, it is judged whether the water sensor 9 is on. If this determination is negative, the process proceeds to step b14 in FIG. If the determination is affirmative, the process proceeds to step b11 to continue the closed state of the solenoid valve 30 and the extinguished state of the induction lamp 15. The determination in step b13 is affirmative in the following cases as an example. That is, when the finger detected by the water sensor 9 in step b7 remains in the detection range of the water sensor 9 even if the electromagnetic valve 30 is switched from the open state to the closed state, or For example, the finger detected by the sensor 9 is once removed from the detection range of the water sensor 9 and then inserted again into the detection range of the water sensor 9. When the open state of the solenoid valve 30 for the time limit T14 ends, water can be immediately discharged from the nozzle 6 unless the soap liquid or the disinfectant liquid is discharged or sprayed from the other nozzles 7 and 8. To be prevented.

(2) Processing relating to hand washing with soap solution In step b14 of FIG. 13, the guide lamp 19 for prompting the user to wash hands with soap solution blinks at time t24 as shown in FIG. 11 (2). To be done. Step b

FIG. 14 is a flow chart showing the details of the processing in step b16 mentioned above. In step c1, it is determined whether or not the float switch 25 detects that the amount of soap liquid in the tank 23 is relatively small, that is, whether or not the float switch 25 is turned on. If the determination in step c1 is affirmative, step c2
At this time, after the float switch 25 is turned on, every time the soap liquid discharge pump 27 is driven, a counting operation is performed in which the driving number n1 is incremented by +1.
It is determined whether the counting result n1 has reached a predetermined numerical value N1. If this judgment is negative, step c
At 3, the lamp 18 that prompts the replenishment of soap solution blinks.
Then, the process proceeds to step b17. Step c
If the determination of 2 is affirmative, the lamp 18 is turned on in step c4, and the discharge of soap solution is prohibited in step c5. In this prohibition process, for example, the control circuit 47 may set a predetermined flag to logic "1". After this, the process proceeds to step b17.

That is, when the float switch 25 detects the decrease of the soap solution, the lamp 18 blinks, and the user has a relatively small amount of the soap solution, but the soap solution can be used. Notify that replenishment is required. Furthermore, when the driving number n1 of the pump 27 reaches the above-mentioned numerical value N1, it means that the soap liquid is extremely small, the use of the soap liquid is prohibited, and the soap liquid needs to be immediately replenished. , Inform the user.

On the other hand, if the determination in step c1 is negative, the process proceeds to step c6. Such a judgment is established when the soap solution is sufficiently left in the tank 23 or immediately after the tank solution is replenished with the soap solution. In such a case, in step c6, the lamp 18 is turned off, and in step c7, the driving number n1 is cleared to 0 as an example.
In step c8, the discharge prohibition state of the soap liquid is released. That is, the flag is set to logic "0".
After this, the process proceeds to step b17. In the induction mode of the present embodiment, when the soap liquid is to be discharged, the state of the flag is referred to, and the discharge pump 27 is driven or stopped in accordance with the logical state of the flag.

In step b17, the soap liquid sensor 1

In step b36, as shown in FIG. 11 (13), the solenoid valve 30 for discharging water from the nozzle 6 is switched to the open state, and the water is discharged from the nozzle 6. In step b37, it is determined whether or not the water sensor 9 detects a finger. If this judgment is affirmative, in step b38, the upper limit timer 68 waits until the time limit T17 is measured. When the upper limit timer 68 measures the time limit T17, the off-delay timer 69 is driven in step b39 to measure the time limit T18. If the determination in step b37 is negative, step b39 is executed. That is, the process moves to step b39 depending on the event that the finger is out of the detection range of the water sensor 9 or the upper limit timer 68 measures the time limit T17, whichever occurs first.

At step b40, step b39 is repeatedly executed until the off-delay timer 69 measures the time limit T18 shown in FIG. 11 (13). When the off-delay timer 69 measures the time limit time T18 in step b40, the solenoid valve 30 is switched to the closed state in step b41. In step b42,
The induction lamp 16 is turned off. In step b43, it is determined whether or not the water sensor 9 corresponding to the water discharge nozzle 6 has detected a finger. If this judgment is affirmative, steps b41 to b43 are repeatedly executed.
If the above determination is negative, the processing is step b4 in FIG.

When the determination in step b43 is affirmative, the steps b41 and b42 are repeatedly executed. As described in the processing in steps b11 to b13, once the water discharge from the nozzle 6 is stopped, another This is to prevent the discharge of water from the nozzle 6 from being immediately restarted unless the soap liquid or the disinfectant liquid is discharged or sprayed from the nozzles 7 and 8.

(4) Processing Related to Hand Wiping Operation FIG. 17 is a flowchart showing the hand wiping and disinfectant spray processing in the cleaning device 1. In step b44, the hand-wiping timer 58, which defines the period of the hand-wiping operation for removing water from the fingers, is driven by drying the paper or cloth or warm air after the washing of the fingers with soap solution and water is completed. As shown in 11 (4), at time t29, a predetermined time limit T21 is measured. In step b45, the guide lamp 20 for guiding the user to perform the hand-wiping operation blinks. At this time, the user who has judged that the washing with soap solution or the washing with water in the previous individual work is insufficient, may want these individual work again before moving to the hand-wiping operation.

In step b46, it is judged whether or not the operation button 42 for ejecting the soap liquid is operated. If not, in step b47 it is judged whether or not the operation button 41 for ejecting water is operated. To judge. If the determination in step b46 is affirmative, the processing is as shown in FIG.

In step 1, it is determined whether the float switch 26 detects that the amount of the disinfecting liquid in the tank 24 is relatively small, that is, whether the float switch 26 is turned on. If the determination in step d1 is affirmative, in step d2, the number of times n2 of driving is incremented by +1 each time the spray pump 29 for disinfectant is driven after the float switch 26 is turned on. The operation is performed, and it is determined whether or not the counting result n2 has reached a predetermined numerical value N2. The numerical value N2 is calculated from the spray amount of the antiseptic solution once and the capacity of the tank 24. If the determination in step d2 is negative, the lamp 22 that prompts the supplement of the disinfectant solution blinks in step d3. Then, the process proceeds to step b55 of FIG. 18 described later.

If the determination at step d2 is affirmative,
In step d4, the lamp 22 is turned on, and in step d5, spraying of the disinfecting liquid is prohibited. As the prohibiting process, a predetermined flag may be set to the logic "1" in the control circuit 47 as described above as an example. After this, the process proceeds to step b55. That is, when the float switch 26 detects the decrease of the disinfectant solution, the lamp 22 blinks to inform the user that the disinfectant solution is relatively small and needs to be replenished. Further, when the driving number n2 of the spray pump 29 reaches the numerical value N2, it means that the disinfectant solution is extremely small, spraying of the disinfectant solution is prohibited, and immediate replenishment is necessary. To inform.

On the other hand, if the determination in step d1 is negative, the process proceeds to step d6. Such a judgment is established when the disinfectant solution is sufficiently left in the tank 24 or immediately after the disinfectant solution is replenished in the tank 24. In such a case, in step d6, the lamp 22 is turned off, and in step d7, the driving number n2 is cleared to 0 as an example.
At step d8, the discharge prohibition state of the antiseptic solution is released. That is, the flag is set to logic "0".

The state where 21 is turned off is maintained. That is, once the spraying of the disinfecting liquid from the nozzle 8 is stopped, the spraying of the disinfecting liquid from the nozzle 8 is immediately restarted unless the operation of discharging the water or the soap liquid from the other nozzles 6 and 7 is executed. There is no such thing.

If the determination in step b66 is negative, the initial mode return timer 75 is started in step b67 to measure a predetermined time limit. Step b68
Then, it is judged whether or not the initial mode return timer 75 has timed the time limit. If the judgment is affirmative, the process proceeds to step b1 of FIG. 12 through step b72.

In step b72, a door opening permission signal is output to the automatic door control device 77. Therefore,
When the approach of a person in the washing room to the door is detected by an infrared sensor or the like in the room, the control device 77 drives the motor 78 based on the detection signal from the infrared sensor to open the door. If each individual work is insufficient, the operation of the cleaning apparatus 1 does not reach the step b72. Therefore, even if a person in the washing room approaches the door and the infrared sensor in the room detects the approach of the person, the door is not opened.

If the determination in step b68 is negative, the operation of the operation button 42 for discharging the soap solution is determined in step b69, and if the determination is affirmative, step b1 in FIG.
If the processing is moved to 4 and the determination is negative, the operation of the operation button 41 for discharging water is determined in step b70. If the determination in step b70 is affirmative, the process proceeds to step b28 in FIG. 16, and if not, step b71.
At this time, the operation of the operation button 43 for spraying the disinfectant is judged. If the determination is affirmative in step b71, the process proceeds to step b50 in FIG.

If the determination in step b71 is negative, the process returns to step b68. When the determinations in steps b69 to b71 are negative and the initial mode return timer 75 measures the time limit, the process proceeds to step b1 in FIG. In step b1 of FIG. 12, the guide lamp 15 for instructing the user to pre-wash is blinked as described above. That is, the blinking state of the induction lamp 15 is the initial state of the cleaning device 1 in the first induction mode.

That is, in the period in which the individual operations of pre-washing with water, hand washing with soap solution, hand washing with water, hand-wiping and disinfection are all completed and the initial mode return timer 75 counts the time limit, The user uses each sensor 9
When a finger is extended in any of the detection ranges 1 to 11, water, soap solution, or antiseptic solution is discharged or sprayed from any of the corresponding nozzles 6 to 8. When the initial mode return timer 75 finishes measuring the time limit, the guide lamp 15 that prompts the prewash blinks, and only the finger for the water sensor 9 can be detected.

As described above, the following advantages can be achieved by using the cleaning apparatus 1 of this embodiment.

(1) A single cleaning device 1 is constructed by arranging water discharge nozzles, soap solution discharge nozzles, and disinfectant spray nozzles relatively close to each other. Therefore, when washing the fingers, the user can wash the fingers without moving the body, and the work efficiency of the washing work is improved.

(2) If one individual work is not performed for a predetermined sufficient time, the cleaning device 1 does not guide the user to the next individual work. Therefore, one individual work is performed for each of the induction lamps 15, 16,
It will be continued until the next individual work is guided by 19, 20, 21, 22. Thereby, each individual work can be performed for a predetermined period required for sufficient cleaning of fingers. Therefore, the fingers can be cleaned with high cleanliness.

(3) When one individual work is performed for a predetermined period, the user can see the guide lamps 15, 16, 1
9, 20, 21, and 22 guide you to the next individual work. In such a guided state, when a sensor belonging to the next individual work detects a finger to be washed, water, soap solution, antiseptic solution or the like is ejected or sprayed from the corresponding nozzle. Therefore, it is possible to prevent water, soap liquid, disinfectant liquid, etc. used for the next work to be performed next from being ejected or sprayed under the condition that the fingers are not ejected under the corresponding nozzles. Can be saved. In addition, since the user is not forced to perform the next individual work due to the discharge of water or the like, each individual work can be performed for a period that is determined by the user to be longer than the predetermined period in each individual work. Therefore, the cleanliness of fingers can be significantly improved.

(4) In the cleaning device 1, when the cleaning operation progresses between a plurality of individual works constituting the finger cleaning operation, it is already completed in the intermediate stage before all the cleaning operations are completed. The completed individual work can be easily restarted. As a result, the individual work that the user thinks is insufficient can be performed again, and the cleanliness of the fingers to be washed is significantly improved.

(5) In this embodiment, the cleaning device 1 is installed in the cleaning chamber having an automatic door. Control device 7
In No. 7, the entry into the cleaning chamber is always permitted, and the above-mentioned restrictions are imposed on the exit. That is, the cleaning device 1 outputs a door opening permission signal to the automatic door control device 77 when the finger cleaning operation is sufficiently performed. Therefore, when the approach of a person in the washing room to the door is detected by the infrared sensor or the like in the room, the control device 77 drives the motor 78 based on the detection signal from the infrared sensor to open the door. . On the other hand, if each individual work is insufficient, the cleaning device 1 outputs a door open prohibition signal to the control device 77 for leaving the room. Therefore, in this case, the door is not opened even if a person in the washing room approaches the door. However, when a person outside the room tries to enter the room and approaches the door, the control device drives the motor 78 based on the detection signal of the paired infrared sensor to open the door.

In this way, by controlling the cleaning device 1 to prohibit or permit the opening of the automatic door, a user who has insufficient cleaning of fingers can leave the cleaning room to the outside as it is. It is possible to prevent the occurrence of accidents such as bacterial contamination.

The guiding means of the present invention is not limited to the guiding lamps 15, 16, 19, 20, 21 of the above-mentioned embodiments. As an example, in FIG. 4, a ROM (read only memory) electrically connected to the control circuit 47 is arranged, and the induction lamps 15, 16, 19, 20 are arranged at the mutually divided addresses of the ROM. , 21 may be used to store the voice information data corresponding to the meaning of the guidance operation performed by each. At this time, the voice upper data stored in the ROM is converted into voice by a well-known voice generating circuit and a speaker. Therefore, each induction lamp 15, 16, 19,
Under the condition that 20 and 21 are driven, the guidance information is provided to the user by voice.

Alternatively, image data may be stored in the ROM and a display device such as a liquid crystal panel may be installed on the front side of the cleaning devices 1 and 80. In this example, the guidance information is provided to the user as visual information.

The cleaning devices 1 and 80 use the door of the cleaning chamber in which the cleaning devices 1 and 80 are provided as an automatic door, and output a signal for opening the automatic door when the cleaning operation of the fingers according to a predetermined procedure is completed. I am trying. A cleaning device of the present invention, which does not have a combination with the automatic door, is included in the modification of the present invention.
