以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

本実施形態の洗浄水吐出装置30は、図4に示すように、流し台31のシンク32周縁部に水道カラン(図示せず)と共に併設されるものであり、シンク32の周縁部から立ち上げた支柱91に吐出ノズル1の自立性のある給水路33の下端部が支持されている。なお、給水路33として、自立性がなく、フレキシブルホースであってもよく、支柱91からフレキシブルホースを引き出して使用できるものであってもよい。吐出ノズル1の吐出口3は、図示のように下向き又は少なくとも下向きにできるように配置される。   As shown in FIG. 4, the washing water discharge device 30 according to the present embodiment is provided along with the water supply currant (not shown) at the periphery of the sink 32 of the sink 31, and is raised from the periphery of the sink 32. The support 91 supports the lower end portion of the water supply channel 33 having the self-supporting property of the discharge nozzle 1. Note that the water supply path 33 may be a flexible hose that is not self-supporting, or may be used by pulling the flexible hose from the support column 91. The discharge port 3 of the discharge nozzle 1 is disposed so as to be downward or at least downward as illustrated.

吐出ノズル1の内部構造を説明する。吐出ノズル1は、図2に示すように、直線状に配置した、給水路接続管26、上流管27、下流管28、吐出管29、からなる略筒状のノズル本体部24を備えている。   The internal structure of the discharge nozzle 1 will be described. As shown in FIG. 2, the discharge nozzle 1 includes a substantially cylindrical nozzle main body 24 including a water supply channel connection pipe 26, an upstream pipe 27, a downstream pipe 28, and a discharge pipe 29 arranged in a straight line. .

給水路接続管26の先端部は上流管27の後端部にねじ込むことで接続してあり、上流管27の先端部は下流管28の後端部にねじ込むことで接続してあり、下流管28の先端部は吐出管29の後端部にねじ込むことで接続してあり、これにより給水路接続管26、上流管27、下流管28、吐出管29の夫々の内面によって構成される内部流路5を形成している。   The front end of the water supply channel connecting pipe 26 is connected by screwing into the rear end of the upstream pipe 27, and the front end of the upstream pipe 27 is connected by screwing into the rear end of the downstream pipe 28. 28 is connected to the rear end portion of the discharge pipe 29 by screwing, so that the internal flow constituted by the respective inner surfaces of the water supply channel connection pipe 26, the upstream pipe 27, the downstream pipe 28, and the discharge pipe 29. A path 5 is formed.

ノズル本体部24の先端部(長手方向の一端部)を構成する吐出管29の先端には吐出口3が形成されている。ノズル本体部24の後端部(長手方向の他端部)を構成する給水路接続管26の後端には流入口4を形成してあり、該流入口4が給水路33の下流端に接続され、給水路33からの水道水が洗浄水としてノズル本体部24の流入口4から内部流路5に流入するようになっている。   A discharge port 3 is formed at the tip of a discharge pipe 29 that forms the tip (one longitudinal end) of the nozzle body 24. An inlet 4 is formed at the rear end of the water supply channel connecting pipe 26 constituting the rear end portion (the other end in the longitudinal direction) of the nozzle body 24, and the inlet 4 is formed at the downstream end of the water supply channel 33. Connected, tap water from the water supply channel 33 flows into the internal flow path 5 from the inlet 4 of the nozzle body 24 as cleaning water.

内部流路5の上流には後述する流量調整部90が配置されている。流量調整部09の下流側の内部流路5の途中には、洗浄水流中に気体を混入する気体混入部7と、洗浄水流中に液体の洗剤を供給する洗剤供給部8とが設けてあり、これにより気泡を含む洗浄水又は、気泡及び洗剤を含む洗浄水のうちいずれかを選択的に洗浄水中に混入可能となっている。   A flow rate adjusting unit 90 described later is disposed upstream of the internal flow path 5. In the middle of the internal flow path 5 on the downstream side of the flow rate adjusting unit 09, there are provided a gas mixing unit 7 for mixing gas into the cleaning water flow and a detergent supply unit 8 for supplying liquid detergent into the cleaning water flow. Thus, either cleaning water containing bubbles or cleaning water containing bubbles and detergent can be selectively mixed into the cleaning water.

本例では、気体混入部7による気体の混入、及び、洗剤供給部8による洗剤の供給は、それぞれ、以下述べるように吐出ノズル1の内部流路5を洗浄水が流れる際に生じる負圧を利用している。   In this example, the gas mixing by the gas mixing unit 7 and the detergent supply by the detergent supply unit 8 each have negative pressure generated when the cleaning water flows through the internal flow path 5 of the discharge nozzle 1 as described below. We are using.

内部流路5の一部を構成する上流管27の先端部は内径が下流側程小さくなった絞り部9としてあり、上流管27の絞り部9の出口部付近は洗浄水流によって負圧が生じる負圧発生部6となっている。負圧発生部6の位置は上流管27の先端部の下流管28へのねじ込み深さを調節することで変更可能である。   The distal end portion of the upstream pipe 27 constituting a part of the internal flow path 5 is a throttle portion 9 whose inner diameter becomes smaller toward the downstream side, and a negative pressure is generated in the vicinity of the outlet portion of the throttle portion 9 of the upstream pipe 27 due to the washing water flow. The negative pressure generator 6 is provided. The position of the negative pressure generating portion 6 can be changed by adjusting the screwing depth of the distal end portion of the upstream tube 27 into the downstream tube 28.

下流管28の負圧発生部6に対向する箇所には気体混入部7を構成する大気開放口7aと、洗剤供給部8を構成する洗剤供給口8aとを設けている。   An air opening 7 a that constitutes the gas mixing part 7 and a detergent supply port 8 a that constitutes the detergent supply part 8 are provided at locations facing the negative pressure generating part 6 of the downstream pipe 28.

大気開放口7aは、例えば、吐出ノズル1の外側面と洗剤タンク14との隙間空間に連通しており、噴流洗浄水の吐出時において負圧発生部6で発生する負圧により大気開放口7aから内部流路5に空気が取り込まれ、これにより噴流洗浄水に気泡が混入される。なお大気開放口7aの位置は特に限定されず、適宜に設定変更自在である。   The air release port 7a communicates with, for example, a gap space between the outer surface of the discharge nozzle 1 and the detergent tank 14, and the air release port 7a is generated by the negative pressure generated in the negative pressure generating unit 6 when jet water is discharged. The air is taken into the internal flow path 5 from this, and thereby bubbles are mixed into the jet wash water. Note that the position of the atmosphere opening 7a is not particularly limited, and can be set and changed as appropriate.

洗剤供給口8aはタンク接続用部材20に着脱自在に取り付けた洗剤タンク14にタンク接続用部材20の内部に形成した洗剤流路18を介して連通している。タンク接続用部材20は下流管28の外面に取り付けてあり、下流管28から外方に向けて突出している。タンク接続用部材20の後面には洗剤流路18の上流端を構成するタンク接続口部21を凹設してある。   The detergent supply port 8 a communicates with a detergent tank 14 detachably attached to the tank connecting member 20 via a detergent channel 18 formed inside the tank connecting member 20. The tank connecting member 20 is attached to the outer surface of the downstream pipe 28 and protrudes outward from the downstream pipe 28. A tank connection port 21 constituting the upstream end of the detergent flow path 18 is recessed in the rear surface of the tank connection member 20.

洗剤タンク14は、吐出ノズル1の長手方向に細長い略直方体状に形成してある。なお図2中の50は洗浄水量確認用窓である。また図中の16は内部流路5を開いて吐水を行なう吐水レバーであり、25はレバー軸であり、23は上流管27の内部に収納されたレバーコックであり、吐水レバー16を閉じる方向a1に握ると吐水レバー16の基端部16aがレバーコック23に突設した係合部23aを後方b1に押してレバーコック23の先端外面に装着したOリング23bを上流管27の内周面に設けた弁座面から離して内部流路5を開放する。また吐水レバー16を離すとバネ(図示せず)によって吐水レバー16が開く方向a2に回動してレバーコック23が前方向b2に押されてOリング23bが上流管27の弁座面に当接することで内部流路5が閉じられるようになっている。   The detergent tank 14 is formed in a substantially rectangular parallelepiped shape elongated in the longitudinal direction of the discharge nozzle 1. In addition, 50 in FIG. 2 is a washing water amount confirmation window. Further, in the figure, 16 is a water discharge lever that opens the internal flow path 5 to discharge water, 25 is a lever shaft, 23 is a lever cock housed inside the upstream pipe 27, and the direction in which the water discharge lever 16 is closed. When grasped by a1, the base end portion 16a of the water discharge lever 16 pushes the engaging portion 23a projecting from the lever cock 23 to the rear b1, and the O-ring 23b attached to the outer surface of the tip of the lever cock 23 is formed on the inner peripheral surface of the upstream pipe 27. The internal flow path 5 is opened away from the provided valve seat surface. When the water discharge lever 16 is released, the spring (not shown) rotates the water discharge lever 16 in the opening direction a2, the lever cock 23 is pushed in the front direction b2, and the O-ring 23b contacts the valve seat surface of the upstream pipe 27. The internal flow path 5 is closed by contact.

洗剤タンク14の先端部には洗剤タンク14内に連通する被接続口部22を突設している。洗剤タンク14の後端部には洗剤を補給するための洗剤補給口15を設けてあり、洗剤補給口15は該洗剤補給口15に着脱自在に取り付けたキャップ19により閉塞してある。   A connected port portion 22 that communicates with the inside of the detergent tank 14 protrudes from the tip of the detergent tank 14. A detergent supply port 15 for supplying detergent is provided at the rear end of the detergent tank 14, and the detergent supply port 15 is closed by a cap 19 that is detachably attached to the detergent supply port 15.

洗剤タンク14はノズル本体部24の後部を構成する上流管27の外面に沿わせると共に被接続口部22を吐出ノズル1のタンク接続口部21に嵌め込んだ状態で吐出ノズル1に取り付けられる。   The detergent tank 14 is attached to the discharge nozzle 1 along the outer surface of the upstream pipe 27 constituting the rear portion of the nozzle main body 24 and with the connected port portion 22 fitted in the tank connection port portion 21 of the discharge nozzle 1.

タンク接続用部材20の洗剤流路18には洗剤用開閉弁17を設けている。洗剤用開閉弁17を開閉することで洗剤タンク14と内部流路5の連通・非連通状態を切替可能としてあり、洗剤用開閉弁17を開いて洗剤タンク14を内部流路5に連通することで、負圧発生部6で発生する負圧により洗剤タンク14内の洗剤を内部流路5を流れる洗浄水流中に供給できるようになっている。   A detergent opening / closing valve 17 is provided in the detergent flow path 18 of the tank connecting member 20. By opening / closing the detergent opening / closing valve 17, it is possible to switch between the communication state / non-communication state of the detergent tank 14 and the internal flow path 5, and opening the detergent opening / closing valve 17 to connect the detergent tank 14 to the internal flow path 5. Thus, the detergent in the detergent tank 14 can be supplied into the cleaning water flow flowing through the internal flow path 5 by the negative pressure generated in the negative pressure generating unit 6.

洗剤用開閉弁17は図示しないばねにより洗剤流路18を遮断する方向に付勢されている。洗剤用開閉弁17を開く場合は、タンク接続用部材20に設けた押釦スイッチ13を前記ばね力に抗して押し込むようにする。また、洗剤用開閉弁17は押釦スイッチ13の非押し込み時には前記ばね力により洗剤流路18を遮断する位置に移動し、洗剤タンク14から内部流路5への洗剤の供給を停止する。これにより洗剤が継続して内部流路5に供給されることを防止できる。   The detergent opening / closing valve 17 is urged in a direction to block the detergent flow path 18 by a spring (not shown). When the detergent opening / closing valve 17 is opened, the push button switch 13 provided on the tank connecting member 20 is pushed against the spring force. Further, when the push button switch 13 is not pushed in, the detergent opening / closing valve 17 moves to a position where the detergent flow path 18 is blocked by the spring force, and stops the supply of detergent from the detergent tank 14 to the internal flow path 5. As a result, the detergent can be prevented from being continuously supplied to the internal flow path 5.

ここでは、気体混入部7から内部流路5に供給される空気の供給量は、洗浄水のボイド率(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水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跳ね抑制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8から内部流路5に供給される洗剤の量は洗浄水の洗剤希釈濃度が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水とすることで、多量の気泡を含むムース状の気泡入り洗浄水とすることができ、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水を吐出でき、水跳ね抑制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7aよりも下流側に洗剤供給口8aを設け、大気開放口7aにて気泡が混入された洗浄水に洗剤供給口8aからの洗剤を供給するようにしてあるが、大気開放口7aよりも上流側に洗剤供給口8aを設けても良いものとする。   Here, the supply amount of air supplied from the gas mixing unit 7 to the internal flow path 5 is set so that the void rate (bubble mixing rate) of the cleaning water is 10 to 30%, and the cleaning effect by the bubbles In addition, the flow of washing water can be prevented from being disturbed by bubbles, and the viscosity of the detergent can be increased to enhance the water splash suppression effect. In addition, the amount of detergent supplied from the detergent supply unit 8 to the internal flow path 5 is set so that the detergent dilution concentration of the washing water is 5000 to 10,000 times. By doing so, it can be made into a mousse-like bubbled wash water containing a large amount of bubbles, the cleaning effect can be enhanced, and bubbled wash water containing a detergent having an appropriate viscosity can be discharged, suppressing water splashing The effect can be enhanced. In the illustrated example, the detergent supply port 8a is provided on the downstream side of the atmosphere opening port 7a, and the detergent from the detergent supply port 8a is supplied to the cleaning water mixed with bubbles at the atmosphere opening port 7a. The detergent supply port 8a may be provided on the upstream side of the atmosphere opening port 7a.

上記吐出ノズル1の内部流路5の一部を構成する下流管28の大気開放口7aよりも下流側部分は減圧・加圧部10となっている。減圧・加圧部10は洗浄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10aと減圧部10aの下流側に位置して下流側程流路径を拡大した加圧部10bとで構成してある。減圧・加圧部10を洗浄水が通過すると、この通過の際に生じる洗浄水の圧力変動に伴って洗浄水が含有す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 downstream side portion of the downstream pipe 28 constituting the part of the internal flow path 5 of the discharge nozzle 1 with respect to the atmosphere opening port 7 a is a pressure reducing / pressurizing unit 10. The depressurizing / pressurizing unit 10 is composed of a venturi-shaped channel whose channel area changes in the flow direction of the washing water, and is located downstream of the depressurizing unit 10a and the depressurizing unit 10a downstream of the depressurizing unit 10a. It is comprised with the pressurization part 10b which expanded the flow path diameter to the side. When the washing water passes through the pressure reducing / pressurizing unit 10, relatively large bubbles contained in the washing water are sheared along with the pressure fluctuation of the washing water generated during the passage, and thereby the bubbles are refined.

下流管28の下流側端部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11を設けている。洗浄水に含まれる気泡は気泡剪断部11の多数の孔を通過することで更に微細化される。   A bubble shearing section 11 having a large number of holes made of a mesh, a porous body, or the like is provided at the downstream end of the downstream pipe 28. The bubbles contained in the washing water are further refined by passing through a large number of holes in the bubble shearing portion 11.

内部流路5の下流側端部を構成する吐出管29の先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12となっている。整流部12の流路長さLは整流部12の直径aの2〜5倍としてあり、洗浄水は整流部12にて整流された後に吐出口3から直線状に吐出される。   The tip of the discharge pipe 29 constituting the downstream end of the internal flow path 5 is a rectifying section 12 having the same flow path diameter in the flow direction of the cleaning water. The flow path length L of the rectifying unit 12 is 2 to 5 times the diameter a of the rectifying unit 12, and the wash water is rectified by the rectifying unit 12 and then discharged linearly from the discharge port 3.

上記洗浄水吐出装置30を用いてシンクの内面や食器等の被洗浄物を洗浄するには、洗剤タンク14を取り付けた吐出ノズル1を把持して吐出口3から洗浄水を被洗浄物に向けて噴射させる。このとき、後述する流量調整部90の操作部90aによって吐出流量の調整を行なうことができる。またこのとき、洗剤用開閉弁17が閉じた状態にある場合は、給水路33から吐出ノズル1に供給された洗浄水には気体混入部7にて気泡が混入され、次に洗浄水に含まれる気泡が減圧・加圧部10及び気泡剪断部11にて微細化され、この後、整流部12で整流された後、吐出口3から微細気泡を含む洗剤入り洗浄水として吐出される。一方、押釦スイッチ13を押して洗剤用開閉弁17が開いた状態にある場合には、給水路33から吐出ノズル1に供給された洗浄水は、気体混入部7にて気泡が混入され、次に洗剤供給部8にて洗剤が供給され、次に、洗浄水に含まれる気泡が減圧・加圧部10及び気泡剪断部11にて微細化され、この後、整流部12で整流された後、吐出口3から吐出される。   In order to clean the object to be cleaned such as the inner surface of the sink or tableware using the cleaning water discharge device 30, the discharge nozzle 1 to which the detergent tank 14 is attached is held and the cleaning water is directed from the discharge port 3 to the object to be cleaned. And spray. At this time, the discharge flow rate can be adjusted by an operation unit 90a of the flow rate adjusting unit 90 described later. Further, at this time, when the detergent opening / closing valve 17 is in a closed state, bubbles are mixed in the cleaning water supplied from the water supply channel 33 to the discharge nozzle 1 in the gas mixing section 7 and then included in the cleaning water. The air bubbles are refined by the pressure reducing / pressurizing unit 10 and the bubble shearing unit 11, and then rectified by the rectifying unit 12, and then discharged from the discharge port 3 as detergent-containing cleaning water containing fine bubbles. On the other hand, when the pushbutton switch 13 is pressed and the detergent opening / closing valve 17 is in the open state, the cleaning water supplied from the water supply channel 33 to the discharge nozzle 1 is mixed with bubbles in the gas mixing section 7, and then After the detergent is supplied by the detergent supply unit 8, the bubbles contained in the washing water are refined by the decompression / pressurization unit 10 and the bubble shearing unit 11, and then rectified by the rectification unit 12, It is discharged from the discharge port 3.

次に、本発明の流量調整部90を備えた吐出ノズル1を説明する。   Next, the discharge nozzle 1 provided with the flow rate adjusting unit 90 of the present invention will be described.

図1〜図3は、請求項1、4に対応する実施形態であり、流し台31に設置される洗浄水吐出装置30は、上記構成の吐出ノズル1と、吐出ノズル1への給水量を調整するための流量調整部90とを備えている。本例では、吐出ノズル1の後端部の給水路接続管26に手動式の流量調整部90を設けてある。この流量調整部90の操作部90aは、給水路接続管26の外面側に突出している。本例の流量調整部90は例えば内部流路5の上流から流入する洗浄水の水量を調整するためのゲート式バルブで構成されており、吐出ノズル1外部から操作部90aの操作によって内部流路5に供給される単位時間当りの給水量が調整可能となっている。   FIGS. 1 to 3 are embodiments corresponding to claims 1 and 4, and the cleaning water discharge device 30 installed in the sink 31 adjusts the discharge nozzle 1 having the above-described configuration and the amount of water supplied to the discharge nozzle 1. And a flow rate adjusting unit 90 for the purpose. In this example, a manual flow rate adjusting unit 90 is provided in the water supply channel connecting pipe 26 at the rear end of the discharge nozzle 1. The operation unit 90 a of the flow rate adjusting unit 90 protrudes to the outer surface side of the water supply channel connecting pipe 26. The flow rate adjusting unit 90 of this example is configured by a gate type valve for adjusting the amount of washing water flowing in from the upstream of the internal flow channel 5, for example, and the internal flow channel is operated by operating the operation unit 90a from the outside of the discharge nozzle 1. The amount of water supply per unit time supplied to 5 can be adjusted.

しかして、水道水圧を利用して吐出ノズル1の吐出口3から洗剤を含む気泡入り洗浄水を高圧で吐出させて、皿や鍋等の被洗浄物の汚れをより確実に除去できるようになるので、手でこすり洗いする必要がなくなり手荒れ防止を図ることができる。さらに、吐出ノズル1に設けた操作部90aによって流量調整部90を操作して内部流路5上流の流路部分の開口面積を増やしたり、減らしたりすることによって、被洗浄物の汚れの付着強度、種類に応じて吐出流量を調整することができる。例えば汚れが少ないときは流量調整部90を絞って小流量とし、強い汚れのときときは流量調整部90を開いて大流量とすることで、水跳ねを抑制でき、また流量を調整するだけで、吐出される洗浄水の性状(流速、水圧等)は変わらないので、洗浄力を高く維持できる構造となる。しかもポンプ等の動力を用いずに、水道水圧を利用した簡易な構造で済むので、吐出ノズル1の低コスト化、節電を図ることができる。   Accordingly, it is possible to more reliably remove dirt on the object to be cleaned such as a dish or a pan by discharging the cleaning water containing bubbles from the discharge port 3 of the discharge nozzle 1 with high pressure using tap water pressure. This eliminates the need for scrubbing by hand, thereby preventing rough hands. Furthermore, by operating the flow rate adjusting unit 90 with the operation unit 90a provided in the discharge nozzle 1 to increase or decrease the opening area of the flow channel portion upstream of the internal flow channel 5, the adhesion strength of the dirt on the object to be cleaned is increased. The discharge flow rate can be adjusted according to the type. For example, when the amount of dirt is small, the flow rate adjustment unit 90 is squeezed to a small flow rate. When the level of dirt is strong, the flow rate adjustment unit 90 is opened to increase the flow rate. Since the properties (flow velocity, water pressure, etc.) of the discharged cleaning water are not changed, the cleaning power can be maintained high. In addition, since a simple structure using tap water pressure can be used without using power such as a pump, the cost of the discharge nozzle 1 can be reduced and power can be saved.

また本例では、微細気泡を混入させたバブル水とすることにより、見かけの体積を増やして吐出速度を高めることができ、通常の水道水に比べて洗浄力(衝撃力)をより高めることができる。さらに気泡混入率を例えば10〜30%程度とすることで、例えば2.5リットル/分程度の比較的低い流量でバブル水を生成・吐出できるものである。さらにバブル水に洗剤を導入することで、バブル水に対する汚れの付着、浸透がそれぞれ高まり、結果、被洗浄物からの汚れの剥離効果が高まることで、油汚れ等に対してより高い洗浄力を持たせることができる。   In addition, in this example, by using bubble water mixed with fine bubbles, the apparent volume can be increased and the discharge speed can be increased, and the cleaning power (impact power) can be further increased compared to normal tap water. it can. Furthermore, by setting the bubble mixing rate to about 10 to 30%, for example, bubble water can be generated and discharged at a relatively low flow rate of about 2.5 liters / minute. Furthermore, by introducing a detergent into the bubble water, the adhesion and penetration of dirt into the bubble water will increase, and as a result, the effect of removing dirt from the object to be washed will increase, resulting in higher detergency against oil stains, etc. You can have it.

ところで、水跳ねの抑制には、上記のように洗浄水の吐出流量を調整することが効果的であるが、さらに加えて洗浄水を整流することも水跳ね抑制に効果的である。本例では吐出口3の先端長さを吐出口3径の2〜5倍程度とすることで、整流効果を持たせるようにしている。さらに加えて、洗浄水に混入させる気泡径を小さくして水流(水束)を乱さないようにするために洗剤入りマイクロバブルを発生させることによって、水跳ねと油汚れ除去により一層効果的な洗浄を実現することができる。   By the way, in order to suppress water splash, it is effective to adjust the discharge flow rate of the wash water as described above. In addition, rectifying the wash water is also effective in suppressing water splash. In this example, the tip length of the discharge port 3 is set to about 2 to 5 times the diameter of the discharge port 3 to provide a rectifying effect. In addition, by generating microbubbles with detergent to reduce the bubble size mixed in the washing water and not disturb the water flow (water bundle), more effective washing by removing water splash and removing oil stains Can be realized.

さらに本例では流量調整部90の操作部90aを吐出ノズル1の後端部に配置しているので、吐出ノズル1を持つ手で操作部90aの操作が可能となる。つまり片手で吐出ノズル1を持って操作部90aを操作しながら、もう片手で被洗浄物を持って洗浄できるようになり、操作性に優れるうえに洗浄作業がはかどる利点もある。   Furthermore, in this example, since the operation part 90a of the flow rate adjustment part 90 is disposed at the rear end part of the discharge nozzle 1, the operation part 90a can be operated by a hand holding the discharge nozzle 1. That is, while the operation part 90a is operated with the discharge nozzle 1 with one hand, the object to be cleaned can be cleaned with the other hand, so that the operability is excellent and the cleaning operation is accelerated.

図5〜図10は請求項2、3に対応する実施形態であり、操作部90aをシンク32周縁部に配置した場合を示している。図5、図7〜図10では、シンク32周縁部より立ち上がる支柱91に吐出ノズル1を支持した構造において、支柱91近傍に操作部90aを配置している。これにより、操作部90aを吐出ノズル1周辺の手の届く範囲に配置することができ、操作部90aによる吐出流量の調整がしやすくなると共に、操作部90aを吐出ノズル1から切り離すことで吐出ノズル1の構造を簡略化できる。なお、流量調整部90の操作部90aは支柱91に限らず、図6に示すように、給水路33の下端部を立ち上げるベース板91´から突設してもよい。この図6の例では給水路33と吐出ノズル1とを着脱自在とすることで、洗剤タンク14や吐出ノズル1の掃除、メンテナンス等が容易にできるようにしている。   5 to 10 show an embodiment corresponding to claims 2 and 3 and show a case where the operation unit 90 a is arranged on the periphery of the sink 32. 5 and 7 to 10, in the structure in which the discharge nozzle 1 is supported by the support column 91 rising from the periphery of the sink 32, the operation unit 90 a is disposed in the vicinity of the support column 91. Accordingly, the operation unit 90a can be disposed within a reachable area around the discharge nozzle 1, the discharge flow rate can be easily adjusted by the operation unit 90a, and the operation unit 90a is separated from the discharge nozzle 1 to thereby discharge the discharge nozzle. The structure of 1 can be simplified. Note that the operation unit 90a of the flow rate adjusting unit 90 is not limited to the support column 91, and may protrude from a base plate 91 'that raises the lower end of the water supply channel 33, as shown in FIG. In the example of FIG. 6, the water supply passage 33 and the discharge nozzle 1 are detachable so that the detergent tank 14 and the discharge nozzle 1 can be easily cleaned and maintained.

ここで、図7〜図9は、支柱91に設けられる手動式の流量調整部90の一例を示している。図7は、支柱91が、操作部として機能する回転可能な上部材90aと、回転不能な下部材90bとで構成されており、上部材90a内部には給水路33に連通する横方向に幅広の流路96aが開口しており、下部材90b内部には水道分岐管に連通する横方向に幅狭の複数の流路97a,97aが開口しており、上部材90aは下部材90bに対して擦り合わせ式で回転可能とされ、上部材90aを矢印N方向のいずれか一方に回転させることで、両流路96a,97aの連通面積を可変にすることができ流量調整ができるものである。なお、図8のように操作部90aの回転操作によって流路内の孔付きボール98を回転させて流路調整を行なうボール式バルブからなる流量調整部90であってもよく、或いは、図9のように操作部90aの押し込み操作によって流路をゲート99で仕切ったり、開いたりするゲート式バルブからなる流量調整部90であってもよい。   Here, FIGS. 7 to 9 show an example of a manual flow rate adjusting unit 90 provided on the support column 91. In FIG. 7, the column 91 is configured by a rotatable upper member 90 a that functions as an operation unit and a non-rotatable lower member 90 b, and the upper member 90 a is wide in the lateral direction communicating with the water supply passage 33. The lower member 90b has a plurality of channels 97a and 97a that are narrow in the lateral direction communicating with the water branch pipe, and the upper member 90a is connected to the lower member 90b. By rotating the upper member 90a in one of the directions indicated by the arrow N, the communication area of both flow paths 96a and 97a can be made variable and the flow rate can be adjusted. . 8 may be a flow rate adjusting unit 90 formed of a ball type valve that adjusts the flow path by rotating the holed ball 98 in the flow path by rotating the operation section 90a, or FIG. In this manner, the flow rate adjusting unit 90 may be a gate type valve that partitions or opens the flow path with the gate 99 by pushing the operating unit 90a.

図10は、支柱91に設けられる電動式の流量調整部90の一例を示している。本例では支柱91内部に、水道分岐管に通じる入口95aと給水路33に通じる出口95bとを備え、入口95aと出口95b間の流路を電動弁で開閉する電動弁ユニット95を組み込み、操作部90aにより電動弁ユニット95を電気的に駆動させて流量調整を行なえるようにしたものである。   FIG. 10 shows an example of an electric flow rate adjusting unit 90 provided on the support column 91. In this example, an electric valve unit 95 that includes an inlet 95a that leads to the water supply branch pipe and an outlet 95b that leads to the water supply channel 33 and opens and closes the flow path between the inlet 95a and the outlet 95b with a motor-operated valve is incorporated in the column 91. The electric valve unit 95 is electrically driven by the portion 90a so that the flow rate can be adjusted.
