Description

本発明は、手動操作弁と、検知センサが検知物を検出している間電流が供給され続けて開く電磁弁とにより、吐水・止水する水栓装置に関する。   The present invention relates to a faucet device that discharges and stops water using a manually operated valve and an electromagnetic valve that is continuously supplied with a current while a detection sensor detects a detected object.

従来から水栓装置として、操作ハンドルの手動操作による吐水弁の開閉と、検知センサの検知物の検知、非検知による吐水弁の開閉とにより水を吐水・止水する水栓装置（例えば、特許文献１参照）が用いられている。この特許文献１に示された水栓装置は、先端部に吐水口が設けられた吐水管と、前記吐水口に検知物が近づいたか否かを検出する前記検知センサと、開閉することで前記吐水口からの吐水、止水を変更する吐水弁と、検知物が近づいたことを検知センサが検出すると前記吐水弁を開くソレノイドと、揺動自在に設けられ操作ハンドルを備えている。操作ハンドルは、揺動されることで前記ソレノイドに前記吐水弁を操作させる状態と、前記ソレノイドと前記吐水弁との間を電気的に遮断して前記吐水弁を強制的に開く状態とに亘って、変位される。   Conventionally, as a faucet device, a faucet device that discharges / stops water by opening / closing a water discharge valve by manual operation of an operation handle, detecting a detection object of a detection sensor, and opening / closing a water discharge valve by non-detection (for example, patent Reference 1) is used. The faucet device shown in this Patent Document 1 opens and closes the water discharge pipe provided with a water discharge port at the tip, the detection sensor that detects whether or not a detection object approaches the water discharge port, A water discharge valve that changes water discharge and water stop from the water discharge port, a solenoid that opens the water discharge valve when the detection sensor detects that the detected object has approached, and a swingable operation handle are provided. The operation handle swings between a state in which the solenoid operates the water discharge valve and a state in which the solenoid and the water discharge valve are electrically disconnected to forcibly open the water discharge valve. Is displaced.

前述した水栓装置は、操作ハンドルが前記ソレノイドに前記吐水弁を操作させる状態に位置付けられて、前記検知センサが前記検知物を検出すると前記ソレノイドが前記吐水弁を開いて、吐水口から水を吐水する。また、前述した水栓装置は、操作ハンドルが前記ソレノイドに前記吐水弁を操作させる状態に位置付けられて、前記検知センサが前記検知物を検出しないと、前記ソレノイドが前記吐水弁を閉じて、吐水口からの水を止水する。さらに、水栓装置は、操作ハンドルが前記ソレノイドと前記吐水弁との間を遮断して前記吐水弁を強制的に開く状態に位置付けられると、吐水口から水を吐水する。   In the water faucet device described above, the operation handle is positioned so that the solenoid operates the water discharge valve, and when the detection sensor detects the detected object, the solenoid opens the water discharge valve, and water is discharged from the water discharge port. Water is discharged. In the water faucet device described above, if the operation handle is positioned in a state where the solenoid operates the water discharge valve, and the detection sensor does not detect the detected object, the solenoid closes the water discharge valve and discharges the water. Stop water from the water outlet. Furthermore, the water faucet device discharges water from the water discharge port when the operation handle is positioned in a state in which the operation handle is shut off between the solenoid and the water discharge valve to forcibly open the water discharge valve.

実開平０３−４０３６４号公報Japanese Utility Model Publication No. 03-40364

ところで、特許文献１に記載されている水栓装置は、一つの吐水弁をソレノイドと操作ハンドルとで操作するので、吐水量が安定せず、適正な水の流量の調整が困難であった。   By the way, since the water faucet device described in Patent Document 1 operates one water discharge valve with a solenoid and an operation handle, the water discharge amount is not stable, and it is difficult to adjust the flow rate of water appropriately.

本発明は、上記の事情に鑑みてなされたものであって、操作ハンドルの操作と、検知センサの検知物の検知、非検知により吐水・止水するものであっても、適正な水の流量の調整を容易に行うことを可能とする水栓装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and even when water is discharged or stopped by operation of the operation handle and detection / non-detection of the detection object of the detection sensor, an appropriate flow rate of water It is an object of the present invention to provide a faucet device that makes it possible to easily perform the adjustment.

上記目的を達成するために、本発明に係る水栓装置は、給水源に連結した給水管と吐水管の吐水口に連通した吐水配管とが接続されて、前記給水管からの水の前記吐水配管への吐水、止水を変更可能な手動操作弁と、前記吐水口に検知物が近づいたか否かを検出する検知センサと、前記給水管と前記吐水配管とに接続したバイパス管に設けられ、かつ電流が供給されていると開き、前記電流の供給が停止されると閉じる連続通電式の電磁弁と、を備え、前記検知センサが前記検知物を検出すると前記電磁弁に電流を供給する水栓装置であって、前記電磁弁は、前記手動操作弁が開くと前記電流の供給が不可能となり、かつ前記手動操作弁が閉じると前記電流が供給可能となることを特徴とする。   In order to achieve the above object, the water faucet device according to the present invention includes a water supply pipe connected to a water supply source and a water discharge pipe connected to a water discharge port of the water discharge pipe, and the water discharge from the water supply pipe. It is provided in a manually operated valve that can change water discharge and water stop to the pipe, a detection sensor that detects whether or not a detection object approaches the water discharge port, and a bypass pipe connected to the water supply pipe and the water discharge pipe. And a continuously energized solenoid valve that opens when current is supplied and closes when supply of the current is stopped, and supplies current to the solenoid valve when the detection sensor detects the detected object. The water faucet device is characterized in that the current cannot be supplied when the manual operation valve is opened, and the current can be supplied when the manual operation valve is closed.

前記水栓装置では、手動操作弁が開くと、電磁弁への電流の供給が不可能となるために、検知センサが検知物としての人体などを検出して電磁弁が開いていても、手動操作弁が開かれると、電磁弁が閉じることとなる。このため、手動操作弁を開くと、電磁弁が開くことがないために、手動操作弁の操作のみによる水が吐水口から吐水されることとなる。したがって、吐水口から吐水される水の流量を手動操作弁のみにより調整することができ、吐水口から吐水される水の流量を容易に調整することができる。   In the water faucet device, when the manually operated valve is opened, it becomes impossible to supply current to the solenoid valve. Therefore, even if the solenoid valve is opened by detecting the human body as the detection object, When the operation valve is opened, the electromagnetic valve is closed. For this reason, when the manually operated valve is opened, the electromagnetic valve does not open, and therefore, water by only the operation of the manually operated valve is discharged from the water outlet. Therefore, the flow rate of water discharged from the water discharge port can be adjusted only by the manual operation valve, and the flow rate of water discharged from the water discharge port can be easily adjusted.

また、前記水栓装置では、前記吐水管は、前記吐水配管を引き出し可能に収容する基部と、前記基部に着脱自在でかつ前記吐水口が設けられたヘッド部と、を備え、前記電磁弁は、前記ヘッド部が前記基部から取り外されると前記電流の供給が不可能となり、かつ前記ヘッド部が前記基部に取り付けられると前記電流が供給可能となることが好ましい。この水栓装置では、ヘッド部を基部から取り外すと、電磁弁への電流の供給が不可能となるために、検知センサが検知物としての人体などを検出して電磁弁が開いていても、ヘッド部が基部から取り外されると、電磁弁が閉じることとなる。このため、ヘッド部が基部から取り外されると、電磁弁が開くことがないために、手動操作弁の操作のみによる水が吐水口から吐水されることとなる。したがって、吐水口から吐水される水の流量を手動操作弁のみにより調整することができ、吐水口から吐水される水の流量を容易に調整することができる。   Further, in the water faucet device, the water discharge pipe includes a base portion that accommodates the water discharge pipe so that the water discharge pipe can be pulled out, and a head portion that is detachably attached to the base portion and provided with the water discharge port. Preferably, the current cannot be supplied when the head portion is detached from the base portion, and the current can be supplied when the head portion is attached to the base portion. In this faucet device, if the head part is removed from the base part, it becomes impossible to supply current to the electromagnetic valve. Therefore, even if the electromagnetic sensor is open by detecting the human body as the detection object, When the head part is removed from the base part, the electromagnetic valve is closed. For this reason, when a head part is removed from a base, since a solenoid valve does not open, water by only operation of a manual operation valve will be discharged from a spout. Therefore, the flow rate of water discharged from the water discharge port can be adjusted only by the manual operation valve, and the flow rate of water discharged from the water discharge port can be easily adjusted.

本発明に係る水栓装置は、手動操作弁が開かれると、電磁弁が開くことがないため、適正な水の流量の調整を容易に行うことができる。   In the water faucet device according to the present invention, when the manually operated valve is opened, the electromagnetic valve does not open, so that it is possible to easily adjust an appropriate flow rate of water.

The water discharge port 25 of the head unit 24 is provided with a filter 27 that switches bubbles and rectification of water to be discharged by being rotated by a switching lever 26.

電磁弁１０は、図４に示すように、バイパス管２２に設けられ、バイパス管２２内の流路を開閉自在である。電磁弁１０は、電源２８から電流が供給されていると開き即ちバイパス管２２を通して給水管１８内の水を直接ホース２１内に導き、電源２８からの電流の供給が停止されると閉じ即ちバイパス管２２を通して給水管１８内の水を直接ホース２１内に導くことを停止する。電磁弁１０は、所謂連続通電式の電磁弁である。即ち、電磁弁１０は、開かれる時のみ電源２８からの電流が供給され、閉じる時には電源２８からの電流が供給されない。なお、電源２８として、周知の電池などの直流電源や、商用電源からの交流電流を直流電流に変換するコンバータなどを用いることができる。   As shown in FIG. 4, the solenoid valve 10 is provided in the bypass pipe 22 and can freely open and close the flow path in the bypass pipe 22. The solenoid valve 10 opens when current is supplied from the power source 28, that is, directs the water in the water supply pipe 18 into the hose 21 through the bypass pipe 22, and closes or bypasses when the current supply from the power source 28 is stopped. Directing the water in the water supply pipe 18 directly into the hose 21 through the pipe 22 is stopped. The solenoid valve 10 is a so-called continuous energization type solenoid valve. That is, the solenoid valve 10 is supplied with current from the power source 28 only when it is opened, and is not supplied with current from the power source 28 when it is closed. As the power source 28, a known DC power source such as a battery, or a converter that converts an AC current from a commercial power source into a DC current can be used.

電磁弁１０に電源２８からの電流を供給する電源系統２９には、図５に示すように、ヘッド部用スイッチ３０と、混合弁用スイッチ３１とが設けられている。ヘッド部用スイッチ３０は、前記電源系統２９に接続しかつ互いに間隔をあけた一対の固定接点３２と、ヘッド部２４に設けられた可動接点３３とを備えている。可動接点３３は、ヘッド部２４が基部２３に取り付けられると、固定接点３２同士を電気的に接続し、ヘッド部２４が基部２３から取り外されると、可動接点３３が固定接点３２から離間して、一対の固定接点３２同士を開放させる。混合弁用スイッチ３１は、前記電源系統２９に接続しかつ互いに間隔をあけた一対の固定接点３４と、湯水混合弁１４に設けられた可動接点３５とを備えている。可動接点３５は、湯水混合弁１４がホース２１への流路を閉じると、固定接点３４同士を電気的に接続し、湯水混合弁１４がホース２１への流路を開くと、可動接点３５が固定接点３４から離間して、一対の固定接点３４同士を開放させる。   As shown in FIG. 5, a power supply system 29 that supplies current from the power supply 28 to the electromagnetic valve 10 is provided with a head portion switch 30 and a mixing valve switch 31. The head unit switch 30 includes a pair of fixed contacts 32 connected to the power supply system 29 and spaced apart from each other, and a movable contact 33 provided on the head unit 24. When the head portion 24 is attached to the base portion 23, the movable contact 33 electrically connects the fixed contacts 32. When the head portion 24 is removed from the base portion 23, the movable contact 33 is separated from the fixed contact 32. The pair of fixed contacts 32 are opened. The mixing valve switch 31 includes a pair of fixed contacts 34 connected to the power supply system 29 and spaced from each other, and a movable contact 35 provided on the hot and cold mixing valve 14. When the hot water mixing valve 14 closes the flow path to the hose 21, the movable contact 35 electrically connects the fixed contacts 34. When the hot water mixing valve 14 opens the flow path to the hose 21, the movable contact 35 A pair of fixed contacts 34 are opened apart from each other.

こうして、電磁弁１０は、湯水混合弁１４が開くと電源２８からの電流の供給が検知センサ１１の検知物の検知、非検知によらず不可能となり、かつ湯水混合弁１４が閉じると電源２８からの電流が供給可能となる。また、電磁弁１０は、ヘッド部２４が基部２３から取り外されると電源２８からの電流の供給が検知センサ１１の検知物の検知、非検知によらず不可能となり、かつヘッド部２４が基部２３に取り付けられると電源２８からの電流が供給可能となる。   Thus, the solenoid valve 10 cannot supply the current from the power source 28 regardless of the detection or non-detection of the detection object of the detection sensor 11 when the hot water mixing valve 14 is opened, and the power source 28 when the hot water mixing valve 14 is closed. The current from can be supplied. Further, when the head portion 24 is removed from the base portion 23, the solenoid valve 10 cannot supply current from the power source 28 regardless of detection or non-detection of the detection object of the detection sensor 11, and the head portion 24 is in the base portion 23. When it is attached to, the current from the power source 28 can be supplied.

検知センサ１１は、図２及び図３に示すように、取付金具７に取り付けられかつ吐水管９の上方に設けられている。検知センサ１１は、周知の赤外線式、光電式などの検知センサを用いることができ、所定の感知エリア内に手などの人体の一部や各種の食器などの検知物が侵入すると、この検知物を検出する非接触式のセンサである。検知センサ１１は、吐水管９に手などの検知物が位置付けられると、この手などの検知物が近付いたことを検出する。検知センサ１１は、検出した結果を制御装置１２に向かって出力する。   As shown in FIGS. 2 and 3, the detection sensor 11 is attached to the mounting bracket 7 and provided above the water discharge pipe 9. As the detection sensor 11, a known infrared type or photoelectric type detection sensor can be used. When a detection object such as a part of a human body such as a hand or various tablewares enters a predetermined detection area, the detection object is detected. It is a non-contact type sensor that detects. When a detection object such as a hand is positioned on the water discharge pipe 9, the detection sensor 11 detects that the detection object such as the hand has approached. The detection sensor 11 outputs the detected result toward the control device 12.

制御装置１２は、図示しないＲＡＭ、ＲＯＭ、ＣＰＵ、入出力ポート及び記憶装置を備えた演算装置である。制御装置１２の入力ポートには、少なくとも検知センサ１１が接続している。制御装置１２の出力ポートには、少なくとも電源２８が接続している。制御装置１２は、検知センサ１１が検出した吐水管９に手などの検知物が近付いたことを示す情報に基づいて、水栓装置１全体の制御をつかさどる。   The control device 12 is an arithmetic device including a RAM, a ROM, a CPU, an input / output port, and a storage device (not shown). At least the detection sensor 11 is connected to the input port of the control device 12. At least a power supply 28 is connected to the output port of the control device 12. The control device 12 controls the entire faucet device 1 based on information indicating that a detection object such as a hand has approached the water discharge pipe 9 detected by the detection sensor 11.

制御装置１２は、検知センサ１１が検知物が近付いたことを検出すると、電源２８に電磁弁１０に電流を供給させる。また、制御装置１２は、検知センサ１１が検知物が近付いたことを検出しないと、電源２８に電磁弁１０に電流を供給させない。電磁弁１０、制御装置１２及び電源２８は、ベースキャビネット３内に収容される。   When the detection sensor 11 detects that the detected object is approaching, the control device 12 causes the power supply 28 to supply current to the electromagnetic valve 10. In addition, the control device 12 does not cause the power supply 28 to supply current to the electromagnetic valve 10 unless the detection sensor 11 detects that the detected object is approaching. The solenoid valve 10, the control device 12 and the power supply 28 are accommodated in the base cabinet 3.

前述した構成の水栓装置１は、図６に示すように、湯水混合弁１４が閉じかつヘッド部２４が基部２３に取り付けられている状態で、検知センサ１１が検知物を検出すると、制御装置１２が電源２８に電磁弁１０に電流を供給させて、電磁弁１０を開き、吐水口２５から水を吐水させる。また、水栓装置１は、ヘッド部２４が基部２３に取り付けられかつ検知センサ１１が検知物を検出し電磁弁１０が開いて吐水している状態で、湯水混合弁１４が開かれると、図６に示すように、混合弁用スイッチ３１が開放して電磁弁１０への電流の供給が不可能となり、電磁弁１０が閉じる。そして、湯水混合弁１４が開いて、吐水口２５から水を吐水させる。また、湯水混合弁１４が閉じると、混合弁用スイッチ３１が閉じて電磁弁１０へ電流が供給されて、電磁弁１０が開いて、吐水口２５から吐水させる。   As shown in FIG. 6, the faucet device 1 having the above-described configuration is configured such that when the detection sensor 11 detects a detection object in a state where the hot water / water mixing valve 14 is closed and the head portion 24 is attached to the base portion 23, the control device 12 causes the power supply 28 to supply current to the electromagnetic valve 10, opens the electromagnetic valve 10, and discharges water from the water outlet 25. In addition, when the hot water / water mixing valve 14 is opened in the state in which the head portion 24 is attached to the base portion 23 and the detection sensor 11 detects a detection object and the electromagnetic valve 10 is open to discharge water, the faucet device 1 As shown in FIG. 6, the mixing valve switch 31 is opened to make it impossible to supply current to the solenoid valve 10, and the solenoid valve 10 is closed. Then, the hot and cold mixing valve 14 is opened, and water is discharged from the water outlet 25. When the hot and cold water mixing valve 14 is closed, the mixing valve switch 31 is closed and a current is supplied to the electromagnetic valve 10, and the electromagnetic valve 10 is opened and water is discharged from the water outlet 25.

水栓装置１は、湯水混合弁１４が閉じかつ検知センサ１１が検知物を検出し電磁弁１０が開いて吐水している状態で、ヘッド部２４が基部２３から取り外されると、図６に示すように、ヘッド部用スイッチ３０が開放して電磁弁１０への電流の供給が不可能となり、電磁弁１０が閉じて、吐水口２５からの水を止水させる。そして、湯水混合弁１４が開くと、吐水口２５から水を吐水させる。ヘッド部２４が基部２３に取り付けられても、湯水混合弁１４が開いていると、吐水口２５から水を吐水させ続ける。その後、湯水混合弁１４が閉じると、検知センサ１１が検知物を検出している間、電磁弁１０を開き、吐水口２５から吐水させる。   The water faucet device 1 is shown in FIG. 6 when the head portion 24 is removed from the base portion 23 in a state where the hot water / water mixing valve 14 is closed and the detection sensor 11 detects the detected object and the electromagnetic valve 10 is open to discharge water. As described above, the head portion switch 30 is opened, and it becomes impossible to supply current to the electromagnetic valve 10, and the electromagnetic valve 10 is closed to stop water from the water outlet 25. Then, when the hot and cold water mixing valve 14 is opened, water is discharged from the water outlet 25. Even if the head portion 24 is attached to the base portion 23, the water continues to be discharged from the water outlet 25 when the hot and cold water mixing valve 14 is open. Thereafter, when the hot and cold water mixing valve 14 is closed, the electromagnetic valve 10 is opened and water is discharged from the water outlet 25 while the detection sensor 11 is detecting the detected object.

上記のように構成された水栓装置１では、湯水混合弁１４が開くと、電磁弁１０への電流の供給が不可能となるために、検知センサ１１が検知物としての人体などを検出して電磁弁１０が開いていても、湯水混合弁１４が開かれると、電磁弁１０が閉じることとなる。このため、湯水混合弁１４を開くと、電磁弁１０が開くことがないために、湯水混合弁１４の操作のみによる水が吐水口２５から吐水されることとなる。したがって、吐水口２５から吐水される水の流量を湯水混合弁１４のみにより調整することができ、吐水口２５から吐水される水の流量を容易に調整することができる。   In the faucet device 1 configured as described above, when the hot and cold mixing valve 14 is opened, it becomes impossible to supply current to the electromagnetic valve 10, so the detection sensor 11 detects a human body or the like as a detection object. Even if the electromagnetic valve 10 is open, the electromagnetic valve 10 is closed when the hot water / water mixing valve 14 is opened. For this reason, when the hot and cold water mixing valve 14 is opened, the solenoid valve 10 is not opened, so that water only by the operation of the hot and cold water mixing valve 14 is discharged from the water outlet 25. Therefore, the flow rate of water discharged from the water discharge port 25 can be adjusted only by the hot water mixing valve 14, and the flow rate of water discharged from the water discharge port 25 can be easily adjusted.

また、水栓装置１では、ヘッド部２４を基部２３から取り外すと、電磁弁１０への電流の供給が不可能となるために、検知センサ１１が検知物としての人体などを検出して電磁弁１０が開いていても、ヘッド部２４が基部２３から取り外されると、電磁弁１０が閉じることとなる。このため、ヘッド部２４が基部２３から取り外されると、電磁弁１０が開くことがないために、湯水混合弁１４の操作のみによる水が吐水口２５から吐水されることとなる。したがって、吐水口２５から吐水される水の流量を湯水混合弁１４のみにより調整することができ、吐水口２５から吐水される水の流量を容易に調整することができる。   Further, in the faucet device 1, when the head portion 24 is removed from the base portion 23, it becomes impossible to supply current to the electromagnetic valve 10. Therefore, the detection sensor 11 detects a human body or the like as a detection object and detects the electromagnetic valve. Even if 10 is open, if the head portion 24 is removed from the base portion 23, the electromagnetic valve 10 will be closed. For this reason, when the head part 24 is removed from the base part 23, the electromagnetic valve 10 does not open, so that water only by the operation of the hot water / mixing valve 14 is discharged from the water outlet 25. Therefore, the flow rate of water discharged from the water discharge port 25 can be adjusted only by the hot water mixing valve 14, and the flow rate of water discharged from the water discharge port 25 can be easily adjusted.

However, the present invention is not limited to the vanity table 2 and may be applied to various housing equipment. Further, in the above-described embodiment, the hot water / water mixing valve 14 is shown as a manual operation valve.
