It can also be switched to an automatic stopping mode to stop the delivery when the sensor 75 does not detect the hands.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acidic water hand washing machine used in hospitals and other health facilities.

[0002]

Recently, attention has been paid to the disinfecting action of strongly acidic water (electrolytic acidic ionized water), and in a hospital room or an operating room, strong acid water is used for disinfection of hands. It has become to. Further, a hand-washing device used in a hospital room or an operating room is desirably a portable hand-washing device in which an installation place can be freely set. For example, as described in Japanese Patent Application Laid-Open No. 7-62699, a portable acid-water hand washing device is used. Has been conventionally proposed.

The acid water hand washer described in the above-mentioned Japanese Patent Application Laid-Open No. 7-62699 has a water supply tank and a waste liquid tank provided inside a main body, and a faucet and a water receiver (hand washer) provided on the main body. is there. The water supply tank for storing the acidic water is connected to the faucet via a pump and a solenoid valve, and the outlet of the water receiver is connected to the waste liquid tank. A sensor for detecting a hand to be cleaned is provided near the faucet.

[0004] When a hand is put out below the faucet, the sensor detects this, and the pump and the solenoid valve operate, so that acidic water is sent from the water supply tank to the faucet.
Discharge from this faucet. The acidic water discharged from the faucet and the waste water after washing are sent to a waste liquid tank from an outlet of a water receiver and stored therein. On the other hand, if the hand is removed from the faucet, the sensor stops detecting the hand, so that the pump stops and the electromagnetic valve closes, thereby stopping the discharge of the acidic water from the faucet.

The water supply tank is detachable from the main body so that the water supply tank can be replaced when the acid water in the water supply tank runs out. Also, the waste tank is detachable from the main body,
When the wastewater in the waste liquid tank is discarded, the waste liquid tank can be removed.

By the way, cleaning with acidic water is at least
It is known that a sufficient disinfection effect cannot be obtained unless it is continuously performed for about 20 seconds or more. However,
In the conventional acid water handwasher, since acidic water is discharged only while the sensor is detecting the hand,
The user does not easily know how long the cleaning has been performed. For example, even 20 seconds is a relatively long time for hand washing, and in practice, a user often only performs washing for less than 20 seconds.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide an acid water hand washing machine capable of reliably obtaining a disinfecting effect by acidic water.

That is, when the sensor as the water supply start means detects the hand to be cleaned by bringing the hand close to the nozzle, the discharge of the acidic water from the nozzle is started. In the forced continuation mode, the discharge of the acidic water is forcibly continued for a predetermined time after the start. On the other hand, in the automatic stop mode, when the sensor stops detecting the hand by releasing the hand from the nozzle, the discharge of the acidic water is stopped. These two modes are switched by switching means. When the user can judge how long to clean, or when strict disinfection is not required, the automatic stop mode can reduce wasteful consumption of acidic water. In the forced continuation mode, the time during which the acidic water is continuously discharged can be adjusted by the discharge time adjusting means, and the time can be set to an appropriate value according to the required degree of disinfection.

Next, the operation of the above configuration will be described. The acidic water hand washer is used for disinfecting hands, for example, in hospital rooms and operating rooms. In addition to hospitals, it is also used for facilities where hygiene is required, such as nursing homes, or for students and teachers to disinfect their hands at school. And this acidic water hand washer can be easily transported by the casters 3 and 4, and can be installed in an appropriate place such as indoors. At the same time, an external 100 V commercial AC power supply can be used as a power supply, and even in a place where a commercial AC power supply cannot be used, the built-in battery 72 can be used as a power supply.

Then, a water supply tank 31 containing strong acid water generated by a generator separate from the acid water hand washer is placed on the main body base 2, and a hook-and-loop fastener 37 is attached to a handle 32 of the water supply tank 31. To stop. As a result, the water supply tank 31 is securely held in the hand washer body 1, and the water supply tank 31 does not fall even when the present acidic water hand washer is carried. At the same time, the strainer 18 and the water supply hose 17 are inserted into the water supply tank 31 from the through hole 36 of the water supply cap 35 screwed into the water supply port 33 of the water supply tank 31. in this way,
The attachment of the water supply tank 31 to the main body 1 of the hand washer is easy.

When washing the hand, the hand is extended below the nozzle 25. Then, the to-be-cleaned object sensor 75 detects the hand as the to-be-cleaned object, the water supply pump 16 is activated, and the water supply is started. That is, the strong acid water stored in the water supply tank 31 is supplied by the water supply hose 17, the water supply pump 16,
The air is sprayed downward from the nozzle 25 and discharged through the hose 19, the water supply flow sensor 21, the hose 22, and the faucet pipe 24 in order. The discharge amount is, for example, 600 ml /
Minutes. The hands are washed with the strongly acidic water sprayed in this manner. Then, in the forced continuation mode, the discharge of the strong acid water continues for the discharge continuation time set from the start of the discharge, that is, for 10 seconds, 20 seconds, 40 seconds, 60 seconds, 80 seconds or 120 seconds. Therefore, if the hand is not released from the nozzle 25 while the strong acid water is being discharged from the nozzle 25, the hand is surely washed for a predetermined time.
On the other hand, in the automatic stop mode, when the hand is released from the nozzle 25 and the sensor 75 stops detecting the hand, the water supply pump 16 stops, and the discharge of the strong acid water stops. In addition, the strongly acidic water discharged from the nozzle 25 or the wastewater after washing is
The water is received by the water receiver 11 of the sink 7, discharged through the drain 52, the joint pipe 53 and the hose 54 of the water receiver 11 into the drain tank 41, and stored there. After washing the hands, the hands can be wiped with the paper towel of the paper towel holder 82.

When the strong acid water in the water supply tank 31 is consumed and the water supply tank 31 is emptied, water is not supplied to the nozzle 25 even if the water supply pump 16 is operated. The feedwater flow sensor 21 monitors whether or not water is flowing through the inside thereof. When the feedwater flow sensor 21 stops detecting the flow of water when the feedwater pump 16 is operating, the feedwater pump 16 stops and the LED 103 Flashes red. This indicates that the water supply tank 31 has become empty. When the water tank 31 is empty,
Is removed once, and the strong acid water is newly added, or the water supply tank 31 is replaced with another water supply tank 31 containing the strong acid water.

The float switch 56 detects that the drain tank 41 is full of waste water. Then, when the float switch 56 is operated, the LED 104 flashes in red to notify that the drain tank 41 is full. To drain the wastewater in the drainage tank 41 to the outside, transport the acidic water hand washer to the drainage area if necessary, and
Is extended to the drainage place, the cock 67 of the drain port 68 is opened, and the push button switch 101 is pressed. This allows the drain pump 6
When the drain pump 61 is driven, the waste water in the drain tank 41 is discharged from its outlet 63 through the hose 62 and the drain pump.
The water is drained to a drainage place through a hose 61, a drainage flow sensor 65, a drainage port 68, and a drainage hose 69 in this order. During drainage, the LED 105 flashes red. During draining, the drainage flow sensor 65 monitors whether water is flowing inside the drainage tank.However, when the drainage tank 41 becomes empty and the drainage flow sensor 65 stops detecting water flow, The drain pump 61 stops. Thereafter, the cock 67 is closed again.

Since the drain pump 61 can be driven by an external commercial AC power supply or a built-in battery 72, drainage work can be performed not only in a place where an external commercial AC power supply can be used but also in a place where an external AC power supply cannot be used. .

Further, the water supply pump 16 and the drainage pump 61 can be operated at the same time, so that the hands can be washed even while the drainage from the drainage tank 41 is being performed.

When the power cord is connected to an external commercial AC power supply, the secondary battery 72 is charged. When the capacity of the secondary battery 72 is sufficient, the LED 102 lights in green, but when the discharge of the secondary battery 72 is completed, the LED 102 turns on.
102 flashes in red, which indicates that the secondary battery 72 needs to be charged. During this charging, LED102
Lights in orange.

As described above, according to the configuration of the above-described embodiment, the disinfecting effect of the strongly acidic water cannot be sufficiently obtained unless the cleaning is performed for a predetermined period of time. The cleaning object sensor 75 detects the hand and the nozzle 25
Since the discharge of the strong acid water continues for a predetermined time after the discharge of the strong acid water from the nozzle 25, if the hand is not released from the nozzle 25 while the strong acid water is being discharged from the nozzle 25, The hands can be washed for a predetermined time. Therefore, the disinfecting effect of the strongly acidic water can be reliably obtained.

By operating the push button switches 91 and 92, the discharge continuation time of the strongly acidic water can be reduced from 10 seconds to 120 seconds.
It can be freely switched to seconds, and the discharge duration can be adjusted to an appropriate one according to the intended use of the acidic water hand washer and the required degree of disinfection. For example, when careful disinfection is required in a hospital or the like, a long discharge duration is set, whereas strict disinfection is not required, whereas in schools where many people have to perform cleaning, , To shorten the discharge duration. Thereby, useless consumption of the strongly acidic water can be reduced.

Further, by operating the push button switches 91 and 92, a forced continuation mode in which the discharge of the strong acid water continues for a predetermined time, and the strong acid water is discharged only while the object to be cleaned sensor 75 detects the hand. The mode can be switched between an automatic stop mode for discharging. For example, the automatic stop mode may be set when the user can determine for how long the cleaning should be performed, or when strict disinfection is not required. This can also reduce wasteful consumption of acidic water.

Further, since a drain port 68 with an opening / closing device for discarding waste water in the drain tank 41 is provided in the outer shell portion of the hand basin body 1 at a position above the center in the vertical direction,
When opening and closing the cock 67 of the drain port 68, the operator does not need to bend down deeply and can easily perform drainage work.

Next, a second embodiment of the acidic water hand washer of the present invention will be described with reference to FIG. Since the acidic water hand washer of the second embodiment has substantially the same configuration as the acid water hand washer of the first embodiment, the same reference numerals are given to portions corresponding to those of the first embodiment. The description is omitted. That is, the acidic water hand washer of the second embodiment is different from the first embodiment in that the paper towel holder 82 of the first embodiment is not provided. The main body cover 126 is provided to cover the main body. The front wall of the main body cover 126 is an openable and closable door 128 rotatably supported by a hinge 127. By opening the front surface of the main body cover 126, the water supply tank 31 can be attached and detached. It has become.

According to the structure of the second embodiment, the body cover
126 enhances the appearance and the water tank
The effect is obtained that the protection of 31 can be ensured. On the other hand, if the water supply tank 31 has a structure that is always exposed as in the first embodiment, there is an advantage that the work of attaching and detaching the water supply tank 31 can be facilitated.

Note that the present invention is not limited to the above-described embodiment, and various modifications can be made. For example,
In the above embodiment, the discharge duration of the strongly acidic water from the nozzle 25 can be adjusted to six stages of 10 seconds, 20 seconds, 40 seconds, 60 seconds, 80 seconds, and 120 seconds. The time may be set to a time other than the above, or may be adjusted continuously. Further, both the paper towel holder 82 and the main body cover 126 need not be provided. Further, the configuration of each detail can be variously modified.
