以下、本発明を添付図面に示す実施形態に基づいて説明する。図１乃至図７に示す本実施形態の一例の洗浄液吐出装置１は、流し台２に設けたキッチンシンク３に気泡を含む水道水からなる洗浄液又は気泡及び洗剤を含む水道水からなる洗浄液のいずれか一方を選択的に吐出可能なものである。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The cleaning liquid discharge device 1 according to an example of the present embodiment shown in FIGS. 1 to 7 is either a cleaning liquid made of tap water containing bubbles or a cleaning liquid made of tap water containing bubbles and detergent in the kitchen sink 3 provided in the sink 2. One can be selectively discharged.

図１に示すように、洗浄液吐出装置１は、キッチンシンク３用のカラン４に接続した水道管５に接続される分岐路６と、分岐路６の下流端に設けた吐出ノズル７を備えている。カラン４は従来から利用されているキッチンシンク３用のカランと同様のものであり、図示は省略するが流し台２における後述の吐出ノズル７を支持する立上部９を設けたキッチンシンク３の周縁部上に設けてある。水道管５の分岐路６の上流端を接続した分岐点よりも上流側には図示しない湯沸かし器を設けてあり、湯沸かし器によって所定温度に加熱された湯又は非加熱状態の水が選択的にカラン４や吐出ノズル７に供給されるようにしてある。   As shown in FIG. 1, the cleaning liquid discharge device 1 includes a branch path 6 connected to a water pipe 5 connected to a currant 4 for a kitchen sink 3, and a discharge nozzle 7 provided at the downstream end of the branch path 6. Yes. The currant 4 is the same as the currant for the kitchen sink 3 that has been conventionally used. Although not shown, the peripheral portion of the kitchen sink 3 is provided with a raised portion 9 that supports a discharge nozzle 7 to be described later in the sink 2. It is provided above. A water heater (not shown) is provided on the upstream side of the branch point where the upstream end of the branch path 6 of the water pipe 5 is connected, and hot water heated to a predetermined temperature by the water heater or water in an unheated state is selectively used in the current 4. Or is supplied to the discharge nozzle 7.

分岐路６の下流部は屈曲可能なホース８で構成してあり、ホース８を屈曲して吐出ノズル７の位置や向きを自由に変更できるようになっている。図２及び図３に示すようにホース８は流し台２のキッチンシンク３の周縁部から立ち上げた立上部９の先端から引き出し自在に設けてあり、吐出ノズル７の非使用時にはホース８を立上部９内に収まり良く収納できるようになっている。立上部９は流し台２のキッチンシンク３の周縁部におけるカラン４から離れた位置においてＬ字状に立ち上げられ、その先端部分に吐出ノズル７を着脱自在に取付けることで、吐出ノズル７の吐出口１０を下方のキッチンシンク３内に向けた状態で吐出ノズル７を支持する。   The downstream portion of the branch path 6 is constituted by a bendable hose 8, and the position and direction of the discharge nozzle 7 can be freely changed by bending the hose 8. As shown in FIGS. 2 and 3, the hose 8 is provided so as to be freely drawn out from the tip of the raised portion 9 raised from the peripheral edge of the kitchen sink 3 of the sink 2, and the hose 8 is raised when the discharge nozzle 7 is not used. 9 fits inside and can be stored well. The upright portion 9 is raised in an L-shape at a position away from the currant 4 at the peripheral edge of the kitchen sink 3 of the sink 2, and a discharge nozzle 7 is detachably attached to the tip portion of the upright portion 9. The discharge nozzle 7 is supported in a state where 10 is directed into the lower kitchen sink 3.

分岐路６のホース８よりも上流側の上流部６ａには、上流側から順に、定流量弁１１（減圧弁）、開閉弁１２、逆止弁１３を設けている。また、吐出ノズル７には、上流側から順に気体混入部１４、洗剤供給部１５、気泡微細化部１６（図７参照）、整流部１７（図７参照）を設けている。つまり、分岐路６に供給された水道水は、定流量弁１１（減圧弁）、開閉弁１２、逆止弁１３、気体混入部１４、洗剤供給部１５、気泡微細化部１６、整流部１７を順に通過した後に吐出ノズル７の吐出口１０から吐出する。   A constant flow valve 11 (pressure reducing valve), an on-off valve 12, and a check valve 13 are provided in this order from the upstream side in the upstream portion 6a upstream of the hose 8 of the branch path 6. Further, the discharge nozzle 7 is provided with a gas mixing unit 14, a detergent supply unit 15, a bubble refining unit 16 (see FIG. 7), and a rectifying unit 17 (see FIG. 7) in order from the upstream side. That is, the tap water supplied to the branch path 6 is a constant flow valve 11 (pressure reducing valve), an on-off valve 12, a check valve 13, a gas mixing unit 14, a detergent supply unit 15, a bubble refinement unit 16, and a rectification unit 17. Are sequentially discharged, and then discharged from the discharge port 10 of the discharge nozzle 7.

定流量弁１１は水道圧により水道管から分岐路６に供給された水道水を減圧し且つ流量を一定にして下流側へと送る。開閉弁１２は図４に示すように制御部を構成する制御基盤１９と共に電磁弁ユニット３０に内装した電磁弁１２ａからなる。開閉弁１２の開閉は立上部９の根元部の外面に設けた開閉弁操作部１８の操作により切り替えられ、このように開閉弁１２の開閉を切り替えることで吐出口１０から洗浄液を吐出するか否かを切り替える。開閉弁操作部１８はキッチンシンク３の周縁部から立ち上げた立上部９に設けてあるので、キッチンシンク３を利用する使用者にとって非常に近い位置にあり使い勝手が良い。なお、開閉弁操作部１８は立上部９のその他の部分に設けてあっても良く、例えば図８に示すように立上部９の根元部から流し台２の上面に沿って横方向に突出した部分の上面に設けても良い。また、開閉弁操作部１８は流し台２のキッチンシンク３の周縁部等、立上部９以外の箇所に設けてあっても良い。   The constant flow valve 11 depressurizes the tap water supplied from the water pipe to the branch path 6 by the tap pressure, and sends it to the downstream side with a constant flow rate. As shown in FIG. 4, the on-off valve 12 is composed of an electromagnetic valve 12 a housed in an electromagnetic valve unit 30 together with a control base 19 constituting a control unit. The opening / closing of the on / off valve 12 is switched by the operation of the on / off valve operating unit 18 provided on the outer surface of the root portion of the upright portion 9, and whether or not the cleaning liquid is discharged from the discharge port 10 by switching the opening / closing of the on / off valve 12 in this way. Switch between. Since the on-off valve operation part 18 is provided in the upright part 9 raised from the peripheral part of the kitchen sink 3, it is located very close to the user who uses the kitchen sink 3 and is easy to use. The on-off valve operating portion 18 may be provided in other portions of the upright portion 9. For example, as shown in FIG. 8, a portion protruding laterally from the root portion of the upright portion 9 along the upper surface of the sink 2. It may be provided on the upper surface. Moreover, the on-off valve operation part 18 may be provided in places other than the upright part 9, such as the peripheral part of the kitchen sink 3 of the sink 2.

また、開閉弁１２は図５に示すように開閉弁１２を開いてから所定時間ｔ経過後に自動的に開閉弁１２を閉じるように設定してある。具体的には、開閉弁１２が１５分間継続して開いた状態にある時に制御基盤１９の制御により開閉弁１２が自動的に閉じられる。   Further, as shown in FIG. 5, the on-off valve 12 is set to automatically close the on-off valve 12 after a predetermined time t has elapsed since the on-off valve 12 was opened. Specifically, the on-off valve 12 is automatically closed by the control of the control board 19 when the on-off valve 12 is continuously open for 15 minutes.

吐出ノズル７の内部には図７に示す内部流路２０を形成してあり、内部流路２０の上流端がホース８に接続される。内部流路２０の途中には既述の気体混入部１４と洗剤供給部１５を設けてあり、本例の気体混入部１４による気体の混入及び洗剤供給部１５による洗剤の供給は吐出ノズル７の内部流路２０を洗浄水が流れる際に生じる負圧を利用する。   An internal flow path 20 shown in FIG. 7 is formed inside the discharge nozzle 7, and an upstream end of the internal flow path 20 is connected to the hose 8. The gas mixing section 14 and the detergent supply section 15 described above are provided in the middle of the internal flow path 20. Gas mixing by the gas mixing section 14 and supply of detergent by the detergent supply section 15 in this example are performed by the discharge nozzle 7. A negative pressure generated when cleaning water flows through the internal flow path 20 is used.

内部流路２０の一部は内径が下流側程小さくなる絞り部２１により構成してあり、内部流路２０の絞り部２１の出口部付近は洗浄液の吐出時において負圧が生じる負圧発生部２２となっている。   A part of the internal flow path 20 is constituted by a throttle portion 21 whose inner diameter becomes smaller toward the downstream side, and a negative pressure generating portion in which a negative pressure is generated near the outlet of the throttle portion 21 of the internal flow path 20 when the cleaning liquid is discharged. 22

内部流路２０の負圧発生部２２に対向する箇所には気体混入部１４を構成する大気開放口１４ａと洗剤供給部１５を構成する洗剤供給口１５ａを設けている。大気開放口１４ａは吐出ノズル７の外部に連通し、洗浄液の吐出時において負圧発生部２２で発生する負圧により大気開放口１４ａから内部流路２０に空気が取り込まれ、これにより水道水に気泡が混入される。   An air release port 14 a that constitutes the gas mixing unit 14 and a detergent supply port 15 a that constitutes the detergent supply unit 15 are provided at locations facing the negative pressure generation unit 22 of the internal flow path 20. The atmosphere opening port 14a communicates with the outside of the discharge nozzle 7, and air is taken into the internal flow path 20 from the atmosphere opening port 14a due to the negative pressure generated in the negative pressure generating portion 22 when the cleaning liquid is discharged, and thus, into tap water. Air bubbles are mixed in.

洗剤供給口１５ａは吐出ノズル７に着脱自在に取り付けた洗剤タンク２３に洗剤流路２４を介して連通しており、洗剤流路２４には洗剤用開閉弁２５を設けている。洗剤用開閉弁２５の開閉は吐出ノズル７に設けた押釦スイッチ２６ａからなる洗剤用開閉弁操作部２６により切り替えられる。洗剤用開閉弁２５を開閉することで洗剤タンク２３と内部流路２０の連通・非連通状態を切替可能としてあり、洗浄液の吐出時に洗剤用開閉弁２５を開いて洗剤タンク２３が内部流路２０に連通することで、負圧発生部２２で発生する負圧により洗剤タンク２３内の液体の洗剤を内部流路２０を流れる水道水に供給できるようになっている。   The detergent supply port 15 a communicates with a detergent tank 23 detachably attached to the discharge nozzle 7 via a detergent channel 24, and a detergent opening / closing valve 25 is provided in the detergent channel 24. The opening / closing of the detergent opening / closing valve 25 is switched by a detergent opening / closing valve operating unit 26 including a push button switch 26 a provided in the discharge nozzle 7. By opening and closing the detergent opening and closing valve 25, the detergent tank 23 and the internal flow path 20 can be switched between communication and non-communication, and the detergent tank 23 is opened by the internal flow path 20 when the cleaning liquid is discharged. The liquid detergent in the detergent tank 23 can be supplied to the tap water flowing through the internal flow path 20 by the negative pressure generated in the negative pressure generating unit 22.

洗剤用開閉弁２５は図示しないばねにより洗剤流路２４を遮断する方向に付勢されている。洗剤用開閉弁２５を開く場合は、押釦スイッチ２６ａを前記ばね力に抗して押し込む。また、洗剤用開閉弁２５は押釦スイッチ２６ａの非押し込み時には前記ばね力により洗剤流路２４を遮断する位置に移動し、洗剤タンク２３から内部流路２０への洗剤の供給を停止する。これにより意図せずに洗剤が継続して内部流路２０に供給されることを防止できる。   The detergent opening / closing valve 25 is urged in a direction to block the detergent flow path 24 by a spring (not shown). When opening the detergent opening / closing valve 25, the push button switch 26a is pushed against the spring force. The detergent opening / closing valve 25 moves to a position where the detergent flow path 24 is blocked by the spring force when the push button switch 26a is not pushed, and stops the supply of detergent from the detergent tank 23 to the internal flow path 20. Thereby, it can prevent that a detergent continues and is not supplied to the internal flow path 20 unintentionally.

気体混入部１４から内部流路２０に供給される空気の供給量は洗浄液のボイド率（気泡混入率）が１０〜３０％となるように設定してあり、気泡による洗浄効果を高めると共に気泡により洗浄液の流れが乱れることを防止でき、また、洗剤による粘性を高めて水はね防止効果を高めることができるようにしてある。また、洗剤供給部１５から内部流路２０に供給される洗剤の量は洗浄液の洗剤希釈濃度が５０００〜１００００倍となるように設定してあり、洗剤の希釈濃度の高い気泡入り洗浄液とすることで、多量の気泡を含むムース状の気泡入り洗浄液とすることができ、洗浄効果を高めることができ、また適度の粘性を有する洗剤を含む気泡入り洗浄液を吐出でき、水はね防止効果を高めることができるようにしてある。なお、図示例では大気開放口１４ａよりも下流側に洗剤供給口１５ａを設け、大気開放口１４ａにて気泡が混入された洗浄水に洗剤供給口１５ａからの洗剤を供給するようにしてあるが、大気開放口１４ａよりも上流側に洗剤供給口１５ａを設けても良いものとする。   The supply amount of air supplied from the gas mixing unit 14 to the internal flow path 20 is set so that the void ratio (bubble mixing ratio) of the cleaning liquid is 10 to 30%, and the cleaning effect by the bubbles is enhanced and the bubbles The flow of the cleaning liquid can be prevented from being disturbed, and the viscosity of the detergent can be increased to enhance the water splash preventing effect. In addition, the amount of detergent supplied from the detergent supply unit 15 to the internal flow path 20 is set so that the detergent dilution concentration of the cleaning liquid is 5000 to 10,000 times, and the cleaning liquid containing bubbles has a high detergent dilution concentration. Therefore, it is possible to obtain a mousse-like bubble-containing cleaning liquid containing a large amount of bubbles, which can enhance the cleaning effect, and can discharge the bubble-containing cleaning liquid containing a detergent having an appropriate viscosity, thereby improving the water splash preventing effect. I can do it. In the illustrated example, the detergent supply port 15a is provided on the downstream side of the atmosphere opening port 14a, and the detergent from the detergent supply port 15a is supplied to the cleaning water mixed with bubbles at the atmosphere opening port 14a. The detergent supply port 15a may be provided on the upstream side of the atmosphere opening port 14a.

内部流路２０の大気開放口１４ａよりも下流側の流路の一部は減圧・加圧部２７となっている。減圧・加圧部２７は水道水の流れ方向において流路面積が変化するベンチュリ管状の流路からなり、下流側程流路径を縮小した減圧部２７ａと減圧部２７ａの下流側に位置して下流側程流路径を拡大した加圧部２７ｂとで構成してある。減圧・加圧部２７を水道水（なお、洗剤用開閉弁２５の開成時にはこの水道水には洗剤が含まれている）が通過すると、この通過の際に生じる水道水の圧力変動に伴って水道水に含まれる比較的大きな気泡が剪断され、これにより気泡が微細化される。   A part of the flow path on the downstream side of the air flow opening 14 a of the internal flow path 20 is a pressure reducing / pressurizing unit 27. The decompression / pressurization unit 27 is composed of a Venturi-shaped channel whose channel area changes in the direction of tap water flow, and is located downstream of the decompression unit 27a and the decompression unit 27a with the channel diameter reduced toward the downstream side. It is comprised with the pressurization part 27b which expanded the flow path diameter to the side. When tap water (note that this tap water contains detergent when the detergent opening / closing valve 25 is opened) passes through the pressure reducing / pressurizing unit 27, along with the pressure fluctuation of the tap water generated at the time of the passage The relatively large bubbles contained in the tap water are sheared, whereby the bubbles are refined.

内部流路２０の減圧・加圧部２７よりも下流側にはメッシュや多孔質体等からなる多数の孔を有する気泡剪断部２８を設けている。洗浄水に含まれる気泡は気泡剪断部２８の多数の孔を通過することで更に微細化される。   A bubble shearing portion 28 having a large number of holes made of a mesh, a porous body, or the like is provided downstream of the decompression / pressurization portion 27 of the internal channel 20. The bubbles contained in the washing water are further refined by passing through a large number of holes in the bubble shearing portion 28.

内部流路２０の下流側端部は洗浄水の流れ方向において流路径が同一となる整流部１７となっている。整流部１７の流路長さＬは整流部１７の直径ａの２〜５倍としてあり、洗浄水は整流部１７にて整流された後に吐出口１０から直線状に吐出される。   The downstream end portion of the internal flow path 20 is a rectifying section 17 having the same flow path diameter in the flow direction of the cleaning water. The flow path length L of the rectifying unit 17 is 2 to 5 times the diameter a of the rectifying unit 17, and the wash water is rectified by the rectifying unit 17 and then discharged linearly from the discharge port 10.

また、図示は省略するが、吐出ノズル７には吐出口１０への水道水の供給（洗浄液の吐出）を停止するための止水手段を設けている。止水手段は例えば内部流路２０の絞り部２１よりも上流側の箇所に設けた内部流路２０を開閉する機能に加えて流量調整する機能を備えた流量調整機構からなり、吐出ノズル７には流量調整機構を操作するための流量調整機構操作部２９（止水手段操作部）を設けている。   Although not shown, the discharge nozzle 7 is provided with water stop means for stopping the supply of tap water (discharge of cleaning liquid) to the discharge port 10. For example, the water stop means includes a flow rate adjusting mechanism having a function of adjusting the flow rate in addition to the function of opening and closing the internal flow channel 20 provided at a location upstream of the throttle portion 21 of the internal flow channel 20. Is provided with a flow rate adjusting mechanism operating portion 29 (water stop means operating portion) for operating the flow rate adjusting mechanism.

上記洗浄液吐出装置１を用いてキッチンシンク３の内面や食器等の被洗浄物を洗浄するには、開閉弁操作部１８を操作して開閉弁１２を開き、この状態で洗剤タンク２３を取り付けた吐出ノズル７を把持して吐出口１０を被洗浄物に向け、止水手段操作部２９を操作して内部流路２０を開く。   In order to clean an object to be cleaned such as the inner surface of the kitchen sink 3 or tableware using the cleaning liquid discharge device 1, the on-off valve operating portion 18 is operated to open the on-off valve 12, and the detergent tank 23 is attached in this state. The discharge nozzle 7 is gripped, the discharge port 10 is directed toward the object to be cleaned, and the internal flow path 20 is opened by operating the water stop means operation unit 29.

これにより、洗剤用開閉弁２５が閉じた状態にある場合には、分岐路６から吐出ノズル７に供給された水道水は気体混入部１４にて気泡が混入され、次に水道水に含まれる気泡が減圧・加圧部２７及び気泡剪断部２８で構成される気泡微細化部１６にて微細化され、この後、整流部１７で整流された後、吐出口１０から微細気泡を含む洗浄液として吐出される。   Thereby, when the detergent on-off valve 25 is in the closed state, the tap water supplied from the branch path 6 to the discharge nozzle 7 is mixed with bubbles in the gas mixing section 14 and then included in the tap water. The bubbles are refined by the bubble refining unit 16 constituted by the decompression / pressurization unit 27 and the bubble shearing unit 28, and then rectified by the rectifying unit 17, and then the cleaning liquid containing the fine bubbles from the discharge port 10 is used. Discharged.

また、押釦スイッチ２６ａを押し込んで洗剤用開閉弁２５が開いた状態にある場合には、分岐路６から吐出ノズル７に供給された水道水は、気体混入部１４にて気泡が混入され、次に洗剤供給部１５にて洗剤が供給され、次に、水道水に含まれる気泡が減圧・加圧部２７及び気泡剪断部２８にて微細化され、この後、整流部１７で整流された後、吐出口１０から微細気泡及び洗剤を含む洗浄液として吐出される。そして、このように吐出口１０から吐出された微細気泡又は微細気泡及び洗剤を含む洗浄液を被洗浄物に当てて被洗浄物を洗浄する。   Further, when the push button switch 26a is pushed in and the detergent on-off valve 25 is in the open state, the tap water supplied from the branch path 6 to the discharge nozzle 7 is mixed with bubbles in the gas mixing section 14, and next. After the detergent is supplied to the detergent supply unit 15, the bubbles contained in the tap water are refined by the decompression / pressurization unit 27 and the bubble shearing unit 28 and then rectified by the rectification unit 17. The liquid is discharged from the discharge port 10 as a cleaning liquid containing fine bubbles and a detergent. Then, the object to be cleaned is washed by applying the fine bubbles or fine bubbles discharged from the discharge port 10 in this way to the object to be cleaned.

このように本発明の洗浄液吐出装置１は洗剤を含む水道水からなる洗浄効果の高い洗浄液を吐出できるので、被洗浄物を綺麗に洗浄できる。また、気体混入部１４から吐出ノズル７に供給された水道水に気体を供給して気泡を含む水道水からなる洗浄液を吐出できる。この気泡を含む洗浄液は衝撃力が高く洗浄力が高いため、一層洗浄効果を高めることができる。また、既述のように水道圧を利用して洗浄液を吐出できるので別途洗浄液吐出用のポンプを設ける必要がなく、コストを削減できる。また、気泡を含む洗浄液は衝撃力が高く洗浄力が高いので、この点でも洗浄効果が高い。また、洗剤供給部１５は水道管５から最も離れた分岐路６の下流端部の吐出ノズル７に設けているので、洗剤供給部１５から供給された洗剤がキッチンシンク３用のカラン４に通じる水道管５に逆流することを確実に防止できる。 As described above, since the cleaning liquid discharge device 1 of the present invention can discharge a cleaning liquid having a high cleaning effect made of tap water containing a detergent, the object to be cleaned can be cleaned cleanly. Further, Ru can discharge a cleaning liquid comprising a gas tap water supplied to the discharge nozzle 7 from the gas mixing unit 14 from the tap water containing air bubbles is supplied. Since the cleaning liquid containing bubbles has high impact force and high cleaning power, the cleaning effect can be further enhanced. Further, as described above, since the cleaning liquid can be discharged using the water pressure, it is not necessary to separately provide a pump for discharging the cleaning liquid, and the cost can be reduced. Further, since the cleaning liquid containing bubbles has high impact force and high cleaning power, the cleaning effect is high in this respect as well. Moreover, since the detergent supply part 15 is provided in the discharge nozzle 7 of the downstream end part of the branch path 6 furthest from the water pipe 5, the detergent supplied from the detergent supply part 15 leads to the currant 4 for the kitchen sink 3. Backflow to the water pipe 5 can be reliably prevented.

また、本例では洗浄液に含まれる気泡は泡径が非常に小さい微細気泡であるため、汚れへの付着性、浸透性、剥離効果が高く、このため被洗浄物に付着した油汚れをより効果的に落とすことができる。また、この微細気泡は泡径が非常に小さく均一に含まれるために洗浄液の水流を乱しにくく、このため前述の水はねを一層防止できるという効果もある。   Also, in this example, the bubbles contained in the cleaning liquid are fine bubbles with a very small bubble diameter, so the adhesion to dirt, permeability and peeling effect are high, so oil stains adhering to the object to be cleaned are more effective. Can be dropped. Further, since the fine bubbles have a very small bubble diameter and are uniformly contained, the water flow of the cleaning liquid is hardly disturbed, and therefore, the above-described water splash can be further prevented.

また、本例では上記開閉弁１２は電磁弁１２ａであり、即ち弁を電気的に駆動できる電気的駆動弁で構成してあるので、吐出口１０から洗浄液を吐出するか否かを速やかに切り替えることができる。また、この開閉弁１２は制御基盤１９からなる制御部により開いてから所定時間ｔ経過後に自動的に開閉弁１２を閉じるように制御される。従って、既述の止水手段操作部２９によって操作される流量調整機構により内部流路２０を遮断した時に開閉弁１２が開き続けた状態となり、開閉弁１２から吐出ノズル７の流量調整機構までの流路に水道圧がかかって水漏れや破損が生じることを防止できる。   In the present example, the on-off valve 12 is an electromagnetic valve 12a, that is, an electrically driven valve that can electrically drive the valve, so that whether or not the cleaning liquid is discharged from the discharge port 10 is quickly switched. be able to. Further, the on-off valve 12 is controlled so as to automatically close the on-off valve 12 after a predetermined time t has elapsed after being opened by the control unit comprising the control board 19. Therefore, when the internal flow path 20 is shut off by the flow rate adjusting mechanism operated by the water stop means operating portion 29 described above, the on-off valve 12 continues to open, and the flow from the on-off valve 12 to the flow rate adjusting mechanism of the discharge nozzle 7 It is possible to prevent water leakage or breakage due to water pressure applied to the flow path.

なお、上記一例の洗浄液吐出装置１は、開閉弁１２を分岐路６を開閉する電磁弁１２ａにより構成したが、開閉弁１２は手動のものであっても良い。また、開閉弁１２を流量調節可能な電動弁（図示せず）により構成しても良く、電動弁としては開成時における弁の開度を調節可能なものが用いられる。また、この場合、電動弁を操作する開閉弁操作部１８は、上記一例と同様に立上部９の根元部の外面や流し台２におけるキッチンシンク３の周縁部上に設けられるつまみや複数のスイッチ等により構成する。例えば、図６（ａ）には開閉弁操作部１８を流量を段階的に変更可能としたつまみで構成した例が開示してあり、また、図６（ｂ）には開閉弁操作部１８を無段階的に変更するボリュームスイッチで構成した例が開示してある。なお、このように開閉弁１２として流量調節可能とした電動弁を用いる場合には、上記一例における流量調整機構を設けなくても良いものとする。   In the cleaning liquid discharge apparatus 1 of the above example, the on-off valve 12 is configured by the electromagnetic valve 12a that opens and closes the branch path 6, but the on-off valve 12 may be manually operated. Further, the on-off valve 12 may be constituted by an electric valve (not shown) capable of adjusting the flow rate, and an electric valve capable of adjusting the opening of the valve at the time of opening is used. Further, in this case, the on-off valve operating portion 18 for operating the motor operated valve is a knob or a plurality of switches provided on the outer surface of the root portion of the upright portion 9 or the peripheral portion of the kitchen sink 3 in the sink 2 as in the above example. It consists of. For example, FIG. 6A discloses an example in which the on-off valve operation unit 18 is configured with a knob that can change the flow rate stepwise, and FIG. 6B shows the on-off valve operation unit 18. An example of a volume switch that changes steplessly is disclosed. In addition, when using the electric valve which enabled flow volume adjustment as the on-off valve 12 in this way, it is not necessary to provide the flow volume adjustment mechanism in the said example.

また、上記各例の洗浄液吐出装置１は分岐路６の下流部を屈曲自在なホース８により構成したが、屈曲できない金属製の管体等により構成しても良い。また、洗剤タンク２３は吐出ノズル７に設けず、流し台２内に設ける等して、ポンプにより吐出ノズル７の洗剤供給部に供給するものあっても良い。   Further, in the cleaning liquid discharge device 1 of each of the above examples, the downstream portion of the branch path 6 is configured by the bendable hose 8, but may be configured by a metal tube that cannot be bent. Further, the detergent tank 23 may be provided in the sink 2 without being provided in the discharge nozzle 7 and supplied to the detergent supply section of the discharge nozzle 7 by a pump.
