しかしながら、従来の切換え装置では、供給する水の種類を変えるとき、スイッチや蛇口のハンドルなどを操作しなければならず、スイッチなどに触れたときに洗い終えたばかりの手が菌などで汚染されるという課題があった。このとき、スイッチとして近接スイッチを用いれば、スイッチに触れずに水の切換えが可能になるが、手の洗浄の動作と水を切り換えるスイッチの操作とを別々に行うことになり、操作に手間がかかることになる。   However, in the conventional switching device, when changing the type of water to be supplied, the switch and the handle of the faucet have to be operated, and when the switch is touched, the hand just washed is contaminated with bacteria. There was a problem. At this time, if a proximity switch is used as a switch, water can be switched without touching the switch. However, the washing operation of the hand and the operation of the switch for switching the water are performed separately, and the operation is troublesome. It will take.

本発明は、このような従来の課題に着目してなされたもので、手を清潔に保ったままで２種類の水を容易に切り換えることができる注水切換え装置を提供することを目的としている。   The present invention has been made paying attention to such a conventional problem, and an object thereof is to provide a water injection switching device capable of easily switching between two types of water while keeping hands clean.

上記目的を達成するために、本発明に係る注水切換え装置は、医療現場や厨房など衛生面が重視される環境で、手を洗浄するために使用される注水切換え装置であって、第１範囲内の物体を検出する第１近接スイッチと、前記第１範囲より小さく少なくとも一部が前記第１範囲に含まれる第２範囲内の物体を検出する第２近接スイッチと、給水口と第１供給口と第２供給口とを有し、前記第１近接スイッチがオンで前記第２近接スイッチがオフのとき前記給水口を前記第１供給口に接続し、前記第１近接スイッチおよび前記第２近接スイッチがオンのとき前記給水口を前記第２供給口に接続し、前記第１近接スイッチがオフのとき前記給水口と前記第１供給口および前記第２供給口との間を遮断する弁と、前記第２供給口に接続され、中性水から酸性水を生成して送水口に送る酸性水生成器と、前記第１供給口および前記送水口に接続された注水口とを有し、前記第１近接スイッチおよび前記第２近接スイッチは前記注水口の下方に前記第１範囲および前記第２範囲が設定されており、前記第２近接スイッチは前記注水口の下方で前記第１範囲の最下端の検出境界より上方に最下端の検出境界を有することを、特徴とする。
In order to achieve the above object, a water injection switching device according to the present invention is a water injection switching device used for washing hands in an environment where hygiene is important, such as a medical site or a kitchen, and has a first range. A first proximity switch for detecting an object within the second range, a second proximity switch for detecting an object within a second range that is smaller than the first range and at least partially included in the first range, a water supply port, and a first supply A water supply port connected to the first supply port when the first proximity switch is on and the second proximity switch is off, the first proximity switch and the second supply port A valve that connects the water supply port to the second supply port when a proximity switch is on, and shuts off between the water supply port and the first supply port and the second supply port when the first proximity switch is off And neutral water connected to the second supply port. An acidic water generator that generates acidic water and sends the acidic water to a water supply port, and a water injection port connected to the first supply port and the water supply port, wherein the first proximity switch and the second proximity switch are The first range and the second range are set below the water inlet, and the second proximity switch is below the water inlet and above the lowermost detection boundary of the first range. It is characterized by having .

本発明に係る注水切換え装置では、第１近接スイッチおよび第２近接スイッチは、物体の存在を検出することができる非接触型のスイッチから成り、例えば光電スイッチから成る。   In the water injection switching device according to the present invention, the first proximity switch and the second proximity switch are constituted by non-contact type switches that can detect the presence of an object, for example, photoelectric switches.

本発明に係る注水切換え装置は、給水口を水道管などに接続して使用される。第１範囲内に何も検出しないとき、第１近接スイッチはオフになっている。このとき、弁は給水口と第１供給口および第２供給口との間を遮断しており、第１供給口および第２供給口から水は出ない。このため、注水口から水は供給されない。
The water injection switching device according to the present invention is used by connecting a water supply port to a water pipe or the like. When nothing is detected within the first range, the first proximity switch is off. At this time, the valve shuts off between the water supply port and the first supply port and the second supply port, and water does not come out from the first supply port and the second supply port. For this reason, water is not supplied from the water inlet.

第１範囲内に手が入ると、第１近接スイッチがその存在を検出してオンになる。このとき、弁は給水口を第１供給口に接続し、第１供給口から水が出る。これにより、第１供給口に接続されている注水口から水が供給される。
When a hand enters the first range, the first proximity switch detects its presence and turns on. At this time, the valve connects the water supply port to the first supply port, and water is discharged from the first supply port. Thereby, water is supplied from the water injection port connected to the first supply port.

さらに、第１範囲内で第２範囲内に手が入ると、第１近接スイッチとともに第２近接スイッチがその存在を検出してオンになる。このとき、弁は給水口を第２供給口に接続し、第２供給口から水が出る。これにより、第２供給口に接続されている酸性水生成器に水が供給され、酸性水生成器で酸性水が生成される。酸性水生成器により生成した酸性水が送水口を経て注水口から供給されるため、酸性水で手を消毒することができる。
Further, when a hand enters the second range within the first range, the second proximity switch together with the first proximity switch detects its presence and turns on. At this time, the valve connects the water supply port to the second supply port, and water comes out from the second supply port. Thereby, water is supplied to the acidic water generator connected to the second supply port, and acidic water is generated in the acidic water generator. Since the acidic water generated by the acidic water generator is supplied from the water inlet through the water inlet, the hands can be disinfected with the acidic water.

第１範囲内で第２範囲内から手が遠ざかると、第２近接スイッチはオフになって、再び第１供給口を経て注水口から水が供給される。このため、手に付いた酸性水を水道水で洗い流したり、手を水道水で洗浄したりすることができる。さらに、第１範囲内から手が遠ざかると、第１近接スイッチもオフになって、第１供給口および第２供給口のいずれからも水は供給されず、注水口から水は供給されない。このように、本発明に係る注水切換え装置は、給水口の接続先を第１供給口と第２供給口とで切り換えたり、ともに遮断したりすることができる。
When the hand moves away from the second range within the first range, the second proximity switch is turned off, and water is again supplied from the water inlet through the first supply port . For this reason, it is possible to wash away the acidic water on the hand with tap water or wash the hand with tap water. Furthermore, when the hand moves away from the first range, the first proximity switch is also turned off, and water is not supplied from either the first supply port or the second supply port, and water is not supplied from the water injection port. Thus, the water injection switching device according to the present invention can switch the connection destination of the water supply port between the first supply port and the second supply port, or can block both together.

本発明に係る注水切換え装置は、スイッチや蛇口のハンドルなどに触れることなく、手を清潔に保ったままで２種類の水を容易に切り換えることができる。
The water injection switching device according to the present invention can easily switch between two types of water without touching a switch , a faucet handle , or the like while keeping the hand clean.

本発明に係る注水切換え装置では、第１近接スイッチおよび第２近接スイッチがオンからオフ、またはオフからオンに切り換わるとき、その切換えに応じて弁が即座に動作しても、所定の時間をおいてから動作してもよい。   In the water injection switching device according to the present invention, when the first proximity switch and the second proximity switch are switched from on to off or from off to on, even if the valve operates immediately according to the switching, a predetermined time is passed. It may operate after leaving.

本発明に係る注水切換え装置は、第１範囲および第２範囲が注水口の下方に設定されているため、注水口に手を近づける自然の動作で、注水口から酸性水または水道水を出すことができる。また、第２近接スイッチが注水口の下方で第１範囲の最下端の検出境界より上方に最下端の検出境界を有しているため、注水口の下方で手を上下に動かすことにより、酸性水と水道水との切換えを行うことができる。
 In the water injection switching device according to the present invention, the first range and the second range are set below the water injection port, so that acid water or tap water is discharged from the water injection port by a natural operation of bringing a hand close to the water injection port. Can do. Moreover, since the 2nd proximity switch has the detection boundary of the lowest end above the detection boundary of the lowest end of the 1st range below the water injection opening, it is acidic by moving a hand up and down below the water injection opening. Switching between water and tap water can be performed.

なお、第１近接スイッチおよび第２近接スイッチのオン、オフは、手で行うほか、容器や器具など他のいかなるもので行ってもよい。また、第１範囲と第２範囲の範囲の設定は、調整可能であることが好ましい。   Note that the first proximity switch and the second proximity switch may be turned on and off by hand, as well as any other device such as a container or instrument. Moreover, it is preferable that the setting of the range of a 1st range and a 2nd range is adjustable.

この酸性水生成器を用いる構成は、医療現場や厨房など衛生面が重視される環境で好適に使用することができる。   The configuration using the acidic water generator can be suitably used in an environment where hygiene is important, such as a medical site or a kitchen.

本発明によれば、手を清潔に保ったままで２種類の水を容易に切り換えることができる注水切換え装置を提供することができる。   According to the present invention, it is possible to provide a water injection switching device that can easily switch between two types of water while keeping hands clean.

注水切換え装置１０は、医療現場や厨房など衛生面が重視される環境で好適に使用することができる。注水切換え装置１０は、手を洗浄するために好適に使用される。 Next, the operation will be described.
The water injection switching device 10 can be suitably used in an environment where hygiene is important, such as a medical site or a kitchen. The water injection switching device 10 is preferably used for washing hands.

注水切換え装置１０は、第１範囲２１内に何も検出しないとき、第１近接スイッチ１１および第２近接スイッチ１２はオフになっている。このとき、電磁弁１６は給水口１３と第１供給口１４および第２供給口１５との間を遮断しており、第１供給口１４および第２供給口１５から水は供給されない。このため、注水口１９から水は供給されない。   When the water injection switching device 10 does not detect anything within the first range 21, the first proximity switch 11 and the second proximity switch 12 are off. At this time, the electromagnetic valve 16 blocks the water supply port 13 from the first supply port 14 and the second supply port 15, and water is not supplied from the first supply port 14 and the second supply port 15. For this reason, water is not supplied from the water inlet 19.

第１範囲２１内に手が入ると、第１近接スイッチ１１がその存在を検出してオンになる。このとき、電磁弁１６は、給水口１３を第１供給口１４に接続し、第１供給口１４から水道水が出る。これにより、第１供給口１４に接続されている注水口１９から水道水が供給される。   When a hand enters the first range 21, the first proximity switch 11 detects its presence and turns on. At this time, the solenoid valve 16 connects the water supply port 13 to the first supply port 14, and tap water is discharged from the first supply port 14. Thereby, tap water is supplied from the water injection port 19 connected to the first supply port 14.

さらに、第１範囲２１内で手の位置を上げて第２範囲２２内に手が入ると、第１近接スイッチ１１とともに第２近接スイッチ１２がその存在を検出してオンになる。このとき、電磁弁１６は、給水口１３を第２供給口１５に接続し、第２供給口１５から水道水が出る。これにより、第２供給口１５に接続されている酸性水生成器１７に水道水が供給され、酸性水生成器１７で酸性水が生成される。生成された酸性水は、送水口１８を経て注水口１９から供給される。このため、酸性水で手を消毒することができる。   Further, when the hand is moved up within the first range 21 and the hand enters the second range 22, the presence of the second proximity switch 12 together with the first proximity switch 11 is turned on. At this time, the solenoid valve 16 connects the water supply port 13 to the second supply port 15, and tap water comes out from the second supply port 15. Thereby, tap water is supplied to the acidic water generator 17 connected to the second supply port 15, and acidic water is generated by the acidic water generator 17. The generated acidic water is supplied from the water inlet 19 via the water inlet 18. For this reason, it is possible to disinfect hands with acidic water.

第１範囲２１内で手の位置を下げて第２範囲２２内から手が遠ざかると、第２近接スイッチ１２はオフになって、再び第１供給口１４を経て注水口１９から水道水が供給される。このため、手に付いた酸性水を水道水で洗い流したり、手を水道水で洗浄したりすることができる。さらに、第１範囲２１内から手が遠ざかると、第１近接スイッチ１１もオフになって、第１供給口１４および第２供給口１５のいずれからも水は供給されず、注水口１９から水は供給されない。   When the position of the hand is lowered within the first range 21 and the hand moves away from the second range 22, the second proximity switch 12 is turned off, and tap water is supplied from the water injection port 19 through the first supply port 14 again. Is done. For this reason, it is possible to wash away the acidic water on the hand with tap water or wash the hand with tap water. Further, when the hand moves away from the first range 21, the first proximity switch 11 is also turned off, water is not supplied from either the first supply port 14 or the second supply port 15, and water is supplied from the water injection port 19. Is not supplied.

注水切換え装置１０は、給水口１３の接続先を第１供給口１４と第２供給口１５とで切り換えたり、ともに遮断したりすることができる。注水切換え装置１０は、スイッチや蛇口のハンドルなどに触れることなく、手を清潔に保ったままで酸性水および水道水の２種類の水を容易に切り換えることができる。注水切換え装置１０は、第１範囲２１および第２範囲２２が注水口１９の下方に設定されているため、注水口１９に手を近づける自然の動作で、注水口１９から酸性水または水道水を出すことができる。また、第２近接スイッチ１２が、注水口１９の下方で第１範囲２１の最下端の検出境界より上方に最下端の検出境界を有しているため、注水口１９の下方で手を上下に動かすことにより、酸性水と水道水との切換えを行うことができる。   The water injection switching device 10 can switch the connection destination of the water supply port 13 between the first supply port 14 and the second supply port 15, or can block both. The water injection switching device 10 can easily switch between two types of water, acid water and tap water, while keeping hands clean without touching a switch or a faucet handle. Since the first range 21 and the second range 22 are set below the water injection port 19, the water injection switching device 10 is a natural operation of bringing a hand close to the water injection port 19, and acid water or tap water is supplied from the water injection port 19. Can be put out. In addition, since the second proximity switch 12 has a lowermost detection boundary below the water injection port 19 and above the lowermost detection boundary of the first range 21, the hand is moved up and down below the water injection port 19. By moving, it is possible to switch between acidic water and tap water.

なお、第１近接スイッチ１１および第２近接スイッチ１２のオン、オフは、手で行うほか、容器や器具など他のいかなるものでも行うことができる。   The first proximity switch 11 and the second proximity switch 12 can be turned on and off by hand, as well as any other device such as a container or instrument.
