Description

本発明は、水栓に関する。   The present invention relates to a faucet.

水栓の中には、図７（ａ）及び（ｂ）に示すように、「平面摺動方式の弁装置７０」を水栓本体８０の内部に配置したものがある（以下、「従来例１」といい、特許文献１の図１等を参照）。この弁装置７０は、一般に、互いに平面摺動する固定弁体７１及び可動弁体７２を備えると共に、傾動操作及び回動操作を操作態様とするレバー型の操作部７５によって操作される。そして、この弁装置７０が操作されると、水栓本体８０に供給される湯と水の混合と、吐止水の選択と、吐水量の調節とが行われる。   Among the faucets, as shown in FIGS. 7A and 7B, there is a faucet in which a “planar sliding valve device 70” is disposed inside the faucet body 80 (hereinafter referred to as “conventional example”). 1 ”, see FIG. 1 of Patent Document 1). The valve device 70 generally includes a fixed valve body 71 and a movable valve body 72 that slide on each other, and is operated by a lever-type operation unit 75 that operates in a tilting operation and a rotation operation. And if this valve apparatus 70 is operated, the mixing of the hot water supplied to the faucet main body 80, water, selection of the stop water, and adjustment of the amount of water discharge will be performed.

また、自動温度調節機構（サーモスタット方式等）を備える「温度調節用の弁装置」と、この弁装置の２次側に配置される吐止水選択用の弁装置と、を水栓本体に内蔵するタイプの水栓（以下、「従来例２」といい、特許文献２参照の図２等を参照）も用いられている。
特開平９−４２４９４号公報 特開２０００−２４０８２９号公報 The faucet body incorporates a “temperature control valve device” equipped with an automatic temperature control mechanism (thermostat system, etc.) and a valve device for selecting water to be discharged disposed on the secondary side of the valve device. A type of faucet (hereinafter referred to as “conventional example 2”, see FIG. 2 of Patent Document 2) is also used.
JP-A-9-42494 JP 2000-240829 A

ところが、これらの従来例には以下のような問題がある。即ち、この従来例１に示す弁装置７０は、温度調節と吐止水とを行うことが必要なため、弁装置（平面摺動型のカートリッジ）としての流路構造が複雑化し易い。従って、水栓本体内に流入した湯や水が、この弁装置７０を通過するときに、この湯の給湯圧やこの水の給水圧が徒に低下すること（予定外の圧力損失を生ずること）がある。このため、「吐水手段（例えば、カランやシャワー等）」から吐水される湯や水の吐水流量（勢い）を十分に確保できず、水栓の使用勝手が悪くなることがある。   However, these conventional examples have the following problems. That is, since the valve device 70 shown in the conventional example 1 needs to adjust the temperature and stop water, the flow path structure as the valve device (plane sliding type cartridge) is likely to be complicated. Accordingly, when hot water or water that has flowed into the faucet body passes through the valve device 70, the hot water supply pressure or the water supply pressure of the hot water will drop (unexpected pressure loss will occur). ) For this reason, the hot water discharged from the “water discharge means (for example, currant, shower, etc.)” or the water discharge flow rate (momentum) of water cannot be secured sufficiently, and the convenience of use of the faucet may deteriorate.

また、従来例１の水栓は、単一の操作部によって、温度調節用の操作と、吐止水選択用の操作と、吐水量調節用の操作とを行う構造であるため、前に行われた「操作」によってなされた設定が、後に行われる「他の操作」の際に誤って変更され易いという問題を有している。例えば、操作部に温度調節用の操作を施し、所望の温度の湯を吐水しているときに、吐水量の増減のみを意図し、操作部に吐水量調節用の操作を施した。ところが、実際には、意図しない「吐水温度の変更」を生じてしまう可能性があり、従来例１の水栓では、この点からも、使用勝手が悪くなっている。   Further, the faucet of Conventional Example 1 has a structure in which a temperature adjustment operation, a water discharge selection operation, and a water discharge amount adjustment operation are performed by a single operation unit. There is a problem that the setting made by the “operation” is easily changed by mistake during the “other operation” performed later. For example, when an operation for adjusting the temperature is performed on the operation unit and the hot water having a desired temperature is discharged, only the increase and decrease in the amount of water discharge is intended, and the operation for adjusting the water discharge amount is performed on the operation unit. However, in reality, there is a possibility that an unintended “change in water discharge temperature” may occur, and the faucet of the first conventional example is not easy to use.

更に、従来例２の水栓においても、自動温度調節機構が複雑な流路構造を備えるため、水栓本体に流入する湯や水が自動温度調節機構を通過するときに、この湯の給湯圧やこの水の給水圧が徒に低下し、水栓の使用勝手が悪くなることがある。また、自動温度調節機構の構造が複雑で製造コストが掛かるため、水栓の構造の単純化を図ったり、水栓の製造コストの低廉化を図ることが困難であるという問題も有している。更に、自動温度調節機構は、サイズが大型化し易く（例えば、長尺状となり易く）、水栓本体への収納スペースが大きくなり易い。よって、水栓本体のサイズや形状の選択の自由度が低くなるため、デザインの選択の自由度が低くなっているのが実情である。   Further, in the faucet of Conventional Example 2, since the automatic temperature control mechanism has a complicated flow path structure, when hot water or water flowing into the faucet body passes through the automatic temperature control mechanism, In addition, the water supply pressure of this water may drop, and the faucet may be unusable. In addition, since the structure of the automatic temperature control mechanism is complicated and requires a manufacturing cost, it is difficult to simplify the structure of the faucet or to reduce the manufacturing cost of the faucet. . Furthermore, the automatic temperature control mechanism tends to increase in size (e.g., tends to be long), and the storage space in the faucet body tends to increase. Therefore, since the degree of freedom in selecting the size and shape of the faucet body is low, the fact is that the degree of freedom in selecting the design is low.

尚、圧力損失を生じ難い水栓としては、所謂「２ハンドル方式」の水栓を例示できる。この水栓では、湯と水の混合度合いを別個のハンドルを用いて調節する。しかし、この２ハンドル方式の水栓においては、湯側及び水側の両ハンドルを交互に反復操作して、吐水温度と吐水流量を手動で設定するという、面倒なハンドル操作が必要となる。よって、「２ハンドル方式」の水栓においても、使用勝手が悪いという問題を有している。   An example of a faucet that is less likely to cause pressure loss is a so-called “two-handle type” faucet. In this faucet, the mixing degree of hot water and water is adjusted using a separate handle. However, this two-handle water faucet requires a cumbersome handle operation in which both the hot water side handle and the water side handle are alternately operated repeatedly to manually set the water discharge temperature and the water discharge flow rate. Therefore, the “two-handle type” faucet also has a problem of poor usability.

本発明は、上述の課題を解決するものであり、使用勝手が良く、構造の単純化を図ったり、製造コストの低廉化を図ることが容易で、デザインの選択の自由度が高い水栓を提供すること目的とする。   The present invention solves the above-described problems, and is a faucet that is easy to use, simplifies the structure, easily reduces manufacturing costs, and has a high degree of freedom in design selection. The purpose is to provide.

請求項１の発明の水栓は、湯を流入させる湯側の流入路と、水を流入させる水側の流入路と、吐水手段に繋がる流出路と、を具備する水栓本体を備える水栓であって、
前記水栓本体が、
湯側の操作部によって閉弁操作されると、前記湯側の流入路と前記流出路とを非連通な状態とし、該湯側の操作部によって開弁操作されると、前記湯側の流入路と前記流出路とを連通状態とする湯側の吐止水弁と、
水側の操作部によって閉弁操作されると、前記水側の流入路と前記流出路とを非連通な状態とし、該水側の操作部によって開弁操作されると、前記水側の流入路と前記流出路とを連通状態とする水側の吐止水弁と、を備え、
前記湯側の操作部及び前記水側の操作部のうちの少なくとも一方が、上下方向への傾動操作及び左右方向への回動操作の双方、若しくは、一方のみを操作態様とするレバー型の操作部であることを特徴とする。 The faucet of the invention of claim 1 is a faucet provided with a faucet body comprising a hot water inflow passage through which hot water flows in, a water inflow passage through which water flows in, and an outflow passage connected to water discharge means. Because
The faucet body is
When the valve is operated to close by the hot water side operation section, the hot water side inflow path and the outflow path are not communicated, and when the hot water side operation section is operated to open the valve, A hot water-side water stop valve that connects the passage and the outflow passage;
When the water-side operation unit is closed, the water-side inflow path and the outflow path are disconnected from each other, and when the water-side operation unit is opened, the water-side inflow path A water-side water stop valve that makes the passage and the outflow passage communicate with each other,
At least one of the hot water side operation unit and the water side operation unit is a lever-type operation in which both the tilting operation in the up and down direction and the rotating operation in the left and right direction, or only one of them is operated. It is a part.

ここで、本明細書において「左」、「右」、「上」、「下」「前」、「後」等の方向は、使用者を基準に定めたものである。また、本明細書において、「レバー型の操作部を上方に傾動する」とは、例えば、レバー型の操作部（取っ手部）の傾斜角（使用者側に向かって上がり傾斜となる方向を正の方向と仮定する。）を増加させることを指す。更に具体的には、レバー型の操作部を、その所定の部位（例えば、取っ手部の根本側部分）を支点にして上方に持ち上げることを指す。一方、「操作部を下方に傾動する」とは、例えば、レバー型の操作部（取っ手部）の傾斜角を減少させることを指す。更に具体的には、レバー型の操作部を、その所定の部位（例えば、取っ手部の根本側部分）を支点にして下方に押し下げることを指す。   In this specification, directions such as “left”, “right”, “up”, “down”, “front”, “back”, and the like are determined based on the user. Further, in this specification, “tilting the lever-type operation unit upward” means, for example, an inclination angle of the lever-type operation unit (handle unit) (a direction in which the user moves upward toward the user side) It is assumed that the direction is increased.) More specifically, it refers to lifting the lever-type operation unit upward with a predetermined portion (for example, the base side portion of the handle) as a fulcrum. On the other hand, “tilting the operation unit downward” indicates, for example, decreasing the inclination angle of a lever-type operation unit (handle portion). More specifically, it refers to pushing down the lever-type operation portion downward with a predetermined portion thereof (for example, the base side portion of the handle portion) as a fulcrum.

請求項１の発明の水栓は、水栓本体に流入した湯の給湯圧や水栓本体に流入した水の給水圧を徒に低下させる機構を、水栓本体内に配置しない。つまり、その水栓本体の内部において、複雑な流路構造を備える弁装置（前述の「温度調節と吐止水を行う平面摺動方式の弁装置や、自動温度調節機構を備えるサーモスタット方式の温度調節用の弁装置等）を配置しないため、吐水手段から吐水される湯や水の吐水流量（勢い）を十分に確保できる。   The faucet according to the first aspect of the present invention does not have a mechanism for reducing the hot water supply pressure flowing into the faucet body or the water supply pressure flowing into the faucet body within the faucet body. In other words, inside the faucet body, a valve device having a complicated flow path structure (the above-mentioned “sliding valve device for temperature adjustment and water stoppage and thermostat type temperature device having an automatic temperature control mechanism”). Since no adjustment valve device or the like is disposed, it is possible to sufficiently ensure the hot water discharged from the water discharging means and the water discharge flow rate (momentum) of the water.

また、湯側の操作部及び水側の操作部のうちの少なくとも一方（一方の操作部、若しくは、双方の操作部）が、操作性の高い「レバー型の操作部」によって構成される。しかも、単一の「レバー型の操作部」によって、温度調節用の操作と、吐止水用の操作とを行う構造でないため、前に行われた「操作」によってなされた設定が、後に行われる「他の操作」の際に誤って変更されることはない。よって、請求項１の発明の水栓によると、従来の「レバー型の操作部」が備える水栓の長所を生かしつつ、短所を無くすことができる。つまり、「操作部の操作性の高い」という長所を生かしつつ、「意図しない設定変更を生じ易い」という短所を無くすことができる。   Further, at least one of the hot water side operation unit and the water side operation unit (one operation unit or both operation units) is configured by a “lever type operation unit” with high operability. Moreover, since the temperature control operation and the water discharge operation are not performed by a single “lever-type operation unit”, the settings made by the “operation” performed previously are performed later. It is not accidentally changed during “other operations”. Therefore, according to the faucet of the invention of claim 1, it is possible to eliminate the disadvantages while taking advantage of the faucets provided in the conventional “lever-type operation section”. That is, while taking advantage of “high operability of the operation unit”, it is possible to eliminate the disadvantage of “prone to unintended setting change”.

更に、請求項１の発明の水栓では、「湯側の操作部」及び「水側の操作部」のうちの一方を操作したり、双方を操作すれば、吐止水の選択等を行うことができる。   Further, in the faucet of the invention of claim 1, if one of the “hot water side operation part” and the “water side operation part” is operated or both are operated, the discharge water is selected. be able to.

よって、請求項１の発明の水栓は、以上の点から、操作性が高く、使用勝手に優れている。また、請求項１の発明の水栓では、その水栓本体の内部に、構造が複雑で、製造コストや設置スペースが嵩む部品（例えば、前述の「自動温度調節機構を備える温度調節用の弁装置」等）を配置しない。このため、水栓の機構（構造）の簡略化と製造コストの低廉化を図ることが容易である。また、水栓本体のサイズや形状の選択の自由度が高くなるため、水栓のデザインの選択の自由度が高くなる。   Therefore, the faucet of the invention of claim 1 has high operability and excellent usability from the above points. Further, in the faucet of the invention of the first aspect, a component having a complicated structure and a large manufacturing cost and a large installation space (for example, the above-described “temperature control valve having an automatic temperature control mechanism” is provided. Equipment ”etc. is not arranged. For this reason, it is easy to simplify the faucet mechanism (structure) and reduce the manufacturing cost. Moreover, since the degree of freedom in selecting the size and shape of the faucet body is increased, the degree of freedom in selecting the faucet design is increased.

尚、請求項１の発明の水栓では、前述の如く、「湯側の操作部」のみに開放操作（開弁操作）を施し、湯側の流入路に流入する湯のみを吐水してもよいし、「水側の操作部」のみを開放操作（開弁操作）を施し、水側の流入路に流入する水のみを吐水してもよい。これらの場合には、単一の操作部のみに施される「一操作」によって、吐止水の選択等を行うことができるため、水栓をより円滑に操作することができる。但し、請求項１の発明の水栓では、「湯側の操作部」及び「水側の操作部」の双方に開放操作（開弁操作）を施し、湯側の流入路に流入する湯と、水側の流入路に流入する水とを、水栓本体の内部で混合した上で、吐水してもよい。   In the faucet according to the first aspect of the present invention, as described above, only the "hot water side operation section" may be opened (valve opening operation) to discharge only hot water flowing into the hot water side inflow passage. Then, only the “water side operation section” may be opened (valve opening operation), and only water flowing into the water side inflow path may be discharged. In these cases, the water faucet can be operated more smoothly because selection of the water stoppage or the like can be performed by “one operation” performed only on a single operation unit. However, in the faucet of the invention of claim 1, the opening operation (opening operation) is performed on both the “hot water side operation part” and the “water side operation part”, and the hot water flowing into the hot water side inflow passage The water flowing into the inflow channel on the water side may be discharged after being mixed inside the faucet body.

また、請求項１の発明の水栓では、湯側の操作部及び水側の操作部のうちの一方のみをレバー型の操作部とし、他方を「レバー型以外のタイプの操作部」としてもよいし、湯側の操作部及び水側の操作部の双方をレバー型の操作部としてもよい。この「レバー型以外のタイプの操作部」としては、回動操作のみを操作態様とする「ハンドル型の操作部」の他に、押しボタン式の操作部、非接触型の操作部（例えば、センサによって使用者が近接したことを検知して吐止水弁に開弁駆動させ、使用者が離間したことを検知して吐止水弁に閉弁駆動させる操作部）等を例示できる。   In the faucet of the invention of claim 1, only one of the hot water side operation part and the water side operation part may be a lever type operation part, and the other may be a "non-lever type operation part". Alternatively, both the hot water side operation unit and the water side operation unit may be lever-type operation units. As this “operation part of a type other than the lever type”, in addition to a “handle-type operation part” whose operation mode is only a rotation operation, a push button type operation part, a non-contact type operation part (for example, For example, an operation unit that detects that a user has approached by a sensor and drives the discharge water valve to open, and detects that the user has separated and drives the discharge water valve to be closed can be exemplified.

請求項２の水栓は、請求項１に記載の水栓において、
前記水栓本体の外部であって前記湯側の流入路の１次側の部位に、所定の調温手段を配置し、
前記調温手段によって予め所望温度に温度制御された湯が、前記湯側の流入路に流入すると共に、
前記湯側の操作部が、前記レバー型の操作部であることを特徴とする。 The faucet of claim 2 is the faucet of claim 1,
A predetermined temperature control means is disposed outside the faucet body and on the primary side of the inflow channel on the hot water side,
Hot water whose temperature is controlled in advance to a desired temperature by the temperature adjusting means flows into the inflow passage on the hot water side,
The hot water-side operation section is the lever-type operation section.

請求項２の発明は、近年、調温手段（例えば、給湯器）によって行われる「温度制御の精度」が向上したことを考慮してなされたものである。即ち、請求項２の発明においては、水栓本体の１次側で、所望温度に温度制御された「湯」を、湯側の流入路を通じて水栓本体に流入させる。よって、使用者は、調温手段から水栓本体に供給される湯の温度を予め所望温度に設定しておくだけで、より一層、使用勝手の良い状態にて水栓を使用することができる。   The invention of claim 2 has been made in consideration of the recent improvement in “accuracy of temperature control” performed by temperature control means (for example, a water heater). That is, in the invention of claim 2, “hot water” whose temperature is controlled to a desired temperature on the primary side of the faucet body is caused to flow into the faucet body through the inflow passage on the hot water side. Therefore, the user can use the faucet in a more convenient state only by setting the temperature of the hot water supplied from the temperature control means to the faucet body to a desired temperature in advance. .

例えば、湯を吐水させたい場合（風呂への給湯時、洗髪時、手荒い時、食器洗浄時等）には、「湯側の操作部」のみに開放操作（開弁操作）を施せば足り、水を吐水させたい場合（清掃時等）には、「水側の操作部」のみに開放操作（開弁操作）を施せば足りる。つまり、湯側だけ、又は、水側だけの吐水（通水）を行う場合には、一方の操作部に一操作を施せば足りることになる。換言すると、本水栓のサイドでは、温度調節操作を一切行う必要がないことになる。但し、請求項２の発明においても、「湯側の操作部」及び「水側の操作部」の双方に開放操作（開弁操作）を施し、湯側の流入路に流入する湯と、水側の流入路に流入する水とを、水栓本体の内部で混合した上で、吐水してもよい。例えば、「湯側の流入路に供給される湯」の温度が僅かに高い場合に、この湯に「水側の流入路に供給される水」を混合することで、吐水温度の調節（例えば、微調節）を行う態様を例示できる。   For example, if you want to sprinkle hot water (when supplying hot water to the bath, washing your hair, rough hands, washing dishes, etc.), it is sufficient to perform the opening operation (opening operation) only on the "hot water side operation section" If it is desired to discharge water (during cleaning, etc.), it is sufficient to perform an opening operation (valve opening operation) only on the “water side operation section”. That is, when water discharge (water flow) is performed only on the hot water side or only on the water side, it is sufficient to perform one operation on one operation unit. In other words, it is not necessary to perform any temperature adjustment operation on the side of the faucet. However, in the invention of claim 2, both the “hot water side operation portion” and the “water side operation portion” are subjected to an opening operation (valve opening operation), and hot water flowing into the hot water side inflow passage and water The water flowing into the inflow channel on the side may be discharged after being mixed inside the faucet body. For example, when the temperature of “hot water supplied to the hot water inflow passage” is slightly high, mixing the hot water with “water supplied to the water inflow passage” to adjust the discharge water temperature (for example, , Fine adjustment) can be exemplified.

請求項３の水栓は、請求項１又は請求項２に記載の水栓において、
前記湯側の操作部及び前記水側の操作部のうちの一方が、前記レバー型の操作部であると共に、
前記湯側の操作部及び前記水側の操作部のうちの他方が、所定の操作軸を軸心とする回動操作のみを操作態様とするハンドル型の操作部であることを特徴とする。 The faucet of claim 3 is the faucet of claim 1 or claim 2,
One of the hot water side operation part and the water side operation part is the lever type operation part,
The other of the hot water-side operation unit and the water-side operation unit is a handle-type operation unit in which only a rotation operation with a predetermined operation axis as an axis is an operation mode.

請求項３の発明は、２つの操作部の操作性に、意図的な差異を設けたものである。例えば、水栓の中には、「湯側の吐止水弁」を用いた「吐止水」の頻度と、「水側の吐止水弁」を用いた「吐止水」の頻度とが異なる場合がある。つまり、請求項２の発明に従って、「前記水栓本体の外部であって前記湯側の流入路の１次側の部位に、所定の調温手段を配置し、前記調温手段によって予め所望温度に温度制御された湯が、前記湯側の流入路に流入する水栓」においては、「湯側の吐止水弁」を用いた「吐止水」の頻度が、「水側の吐止水弁」を用いた「吐止水」の頻度よりも高くなることがある。この場合、湯側の操作部をレバー型の操作部とし、水側の操作部をハンドル型の操作部とする態様を例示できる。この態様によると、使用頻度の高い「湯側の操作部」の操作性をより高くした構造の水栓、即ち、「使用頻度の高い、湯側の吐止水を優先した構造の水栓」を実現できる。   The invention of claim 3 provides an intentional difference in the operability of the two operation sections. For example, in the faucet, the frequency of “stopping water” using the “water-side stop valve” and the frequency of “stopping water” using the “water-side stop valve” May be different. That is, according to the second aspect of the present invention, “a predetermined temperature adjusting means is disposed outside the faucet body and on the primary side of the inflow passage on the hot water side, and the desired temperature is set in advance by the temperature adjusting means. In the “water faucet where hot water whose temperature is controlled to flow into the hot water side inflow passage”, the frequency of the “water stoppage” using the “water side stop water valve” is “water side stoppage”. It may be higher than the frequency of “stopping water” using a “water valve”. In this case, a mode in which the hot water side operation unit is a lever type operation unit and the water side operation unit is a handle type operation unit can be exemplified. According to this aspect, the faucet having a structure that enhances the operability of the “hot water side operation section” that is frequently used, that is, the “faucet having a structure that prioritizes the hot water side of the water stoppage” Can be realized.

また、請求項３の発明においては、水側の操作部をレバー型の操作部とし、湯側の操作部をハンドル型の操作部としてもよい。この態様は、水栓本体の１次側から「湯側の流入路」に熱湯が流入する可能性がある場合等（例えば、湯側の流入路に流入する「湯」が温度制御されていない場合等）を考慮している。つまり、このタイプ水栓では、「湯側の操作部」を操作性が高い「レバー型の操作部」とすると、「湯側の操作部」を誤った操作方向に一気に操作し、「熱湯」を誤って吐水させてしまう可能性がある。ところが、「湯側の操作部」を操作性が低い「ハンドル型の操作部」とすれば、この「湯側の操作部」を一気に操作することが困難であると共に、操作時における「使用者の注意力」をこの「湯側の操作部」に集中させ易くなるため、「湯側の操作部」の誤操作を防止し易くなる。   In the invention of claim 3, the water side operation section may be a lever type operation section, and the hot water side operation section may be a handle type operation section. In this mode, there is a possibility that hot water may flow from the primary side of the faucet body into the “hot water side inflow passage” (for example, “temperature” of the “hot water” flowing into the hot water side inflow passage is not controlled). Case). In other words, with this type of faucet, if the “hot-side operation unit” is a “lever-type operation unit” with high operability, the “hot-side operation unit” is operated at once in the wrong operating direction. May cause water to be accidentally discharged. However, if the “hot water side operation part” is a “handle-type operation part” with low operability, it is difficult to operate this “hot water side operation part” at once. It is easy to concentrate the “attentive power” on the “hot water side operation section”, so that it is easy to prevent erroneous operation of the “hot water side operation section”.

この「湯側の操作部」の操作性を意図的に低下させる態様は、例えば、社会的な弱者（例えば、幼児、子供、老人等）が使用する可能性が高い水栓に対して特に好適に適用できる。つまり、誤操作を行うと、危険を生ずる可能性がある操作部を弱者等にとって操作し辛いハンドル型の操作部とし、必要に応じて、保護者や介護者等が、この「ハンドル型の操作部」を代わって操作することとすれば、水栓の安全性を高めることができるからである。   The mode of intentionally lowering the operability of this “hot water side operation section” is particularly suitable for faucets that are likely to be used by, for example, socially vulnerable persons (eg, infants, children, elderly people, etc.). Applicable to. In other words, if an incorrect operation is performed, the operation unit that may cause danger is made a handle-type operation unit that is difficult for the weak to operate, and if necessary, a guardian or a caregiver can This is because the safety of the faucet can be improved if the operation is performed instead of "."

請求項４の水栓は、請求項１乃至請求項３の何れかに記載の水栓において、
前記レバー型の操作部には、上下方向への傾動操作及び左右方向への回動操作の双方を施すことが可能であると共に、
該傾動操作及び該回動操作のうちの一方が、前記水栓の吐止水状態を変化させる本操作を構成し、
該傾動操作及び該回動操作のうちの他方が、前記水栓の吐止水状態を維持する空操作を構成することを特徴とする。 The faucet according to claim 4 is the faucet according to any one of claims 1 to 3,
The lever-type operation unit can be subjected to both a tilting operation in the vertical direction and a rotating operation in the horizontal direction,
One of the tilting operation and the turning operation constitutes this operation for changing the water stoppage state of the faucet,
The other of the tilting operation and the turning operation constitutes an empty operation for maintaining the water stoppage state of the faucet.

請求項４の発明では、レバー型の操作部を、傾動操作及び回動操作の双方を施すことが可能な構造とする。そして、この操作部に傾動操作（若しくは、回動操作）を施すと、対応する吐止水弁の開閉弁状態が変化する（水栓の吐止水状態に変化を生じさせる駆動を行う）が、回動操作（若しくは、傾動操作）を施しても、当該吐止水弁の開閉弁状態に変化を生じない（水栓の吐止水状態に変化を生じさせない）。このため、請求項４の発明によると、様々な使用状況に対し、使用勝手が良い水栓が得られる。換言すると、左右への回動方向（若しくは、上下への傾動方向）に振り角（遊び角）を持つため、様々な使用状況に対し、使用勝手が良い水栓となる。以下、この点に関し、具体例を挙げて説明する。また、空操作とは、「操作部に施されていても、水栓の吐止水状態を維持する操作」、つまり、「操作部に施されていても、水栓の吐止水状態に変化を生じさせない操作」を指す。   In a fourth aspect of the invention, the lever-type operation section has a structure capable of performing both tilting operation and rotation operation. Then, when a tilting operation (or a rotation operation) is performed on the operation unit, the corresponding on-off valve state of the water stop valve changes (drive that causes a change in the water stop state of the faucet). Even if a turning operation (or tilting operation) is performed, the on / off valve state of the water stop valve does not change (the water stop state of the faucet does not change). For this reason, according to the invention of claim 4, a faucet having good usability can be obtained for various use situations. In other words, since it has a swing angle (play angle) in the direction of rotation to the left and right (or the direction of tilting up and down), it is a faucet that is easy to use for various usage situations. Hereinafter, this point will be described with a specific example. In addition, the empty operation is “an operation for maintaining the water stoppage state of the faucet even if it is applied to the operation unit”, that is, “the operation of the faucet is performed even if it is applied to the operation unit. “Operation that does not cause change”.

請求項４の発明において、傾動操作を本操作とし、回動操作を空操作とする場合には、使用者と水栓との相対的な位置に関係無く、同様な使用性を確保できる。例えば、使用者が水栓の正面に位置する場合は、レバー型の操作部を正面に向けた状態で、この操作部を上下に傾動操作し、対応する吐止水弁を開閉弁駆動させればよい。一方、使用者が水栓の斜め前方や側方に位置する場合は、レバー型の操作部に回動操作を施し、この操作部を使用者の方向に向けた後に、この操作部に上下への傾動操作し、対応する吐止水弁を開閉弁駆動させることができるからである。   In the invention of claim 4, when the tilting operation is the main operation and the rotation operation is the empty operation, the same usability can be ensured regardless of the relative positions of the user and the faucet. For example, when the user is located in front of the faucet, with the lever-type operation unit facing the front, the operation unit can be tilted up and down to drive the corresponding water stop valve. That's fine. On the other hand, when the user is positioned diagonally forward or sideward of the faucet, the lever-type operation unit is turned, and the operation unit is directed toward the user, and then the operation unit is moved up and down. This is because the corresponding stop water valve can be driven to open and close.

また、傾動操作を空操作とし、回動操作を本操作とする場合には、使用者自身の状況（立っているか、座っているか、大人か、子供か等の状況）に関係無く、同様な使用性を確保できる。例えば、使用者が座っていたり、背が低い子供の場合には、レバー型の操作部を下方に傾動させた状態で、この操作部に開閉操作を施せばよい。一方、使用者が立った状態の大人である場合には、レバー型の操作部を上方に傾動させ状態で、この操作部に開閉操作を施せばよいからである。また、この態様は、幼児等が操作部を操作することを避けたい場合（例えば、熱湯が湯吐水される可能性がある場合）にも有効である。蓋し、レバー型の操作部を上方に傾動させ、幼児等の手が届かないようにすればよいからである。   In addition, when the tilting operation is the empty operation and the rotation operation is the main operation, the same operation is performed regardless of the user's own situation (status of standing, sitting, adult, child, etc.). Usability can be secured. For example, when a user is sitting or a child is short, the operation unit may be opened and closed with the lever-type operation unit tilted downward. On the other hand, when the user is an adult in a standing state, the lever-type operation unit is tilted upward and the operation unit may be opened and closed. This aspect is also effective when an infant or the like wants to avoid operating the operation unit (for example, when hot water may be discharged). This is because the lever-type operation unit is tilted upward so that the hand of an infant or the like cannot be reached.

請求項４の発明において、「水栓の吐止水状態が変化する」とは、例えば、対応する「吐止水弁」、つまり、「請求項４の発明に係るレバー型の操作部によって操作される吐止水弁」の開閉弁状態を変化させ（閉弁状態から開弁状態に変化させたり、開弁状態から閉弁状態に変化させる。）、止水状態にある水栓が吐水状態となったり、吐水状態にある水栓が止水状態となること等を指す。また、この吐止水弁によって吐水量の調節をも行う場合には、この吐止水弁の開度を変化させ（例えば、開弁量を増減させ）、水栓の吐水量を変化させること等も含まれる。   In the invention of claim 4, “the water stop state of the faucet changes” means, for example, a corresponding “water stop valve”, that is, “operated by the lever-type operation portion according to the invention of claim 4. The on / off valve state of the “water discharge valve” is changed (changed from the closed state to the open state, or changed from the open state to the closed state), and the water faucet in the stopped state is in the discharged state It means that the faucet in the water discharge state becomes a water stop state. Further, when the discharge amount is also adjusted by the discharge valve, the opening degree of the discharge valve is changed (for example, the opening amount is increased or decreased), and the discharge amount of the faucet is changed. Etc. are also included.

請求項１〜請求項４の発明において、湯側の操作部と、水湯側の操作部の双方がレバー型の操作部であっても、一方のみがレバー型の操作部であってもよい。また、湯側の操作部と、水湯側の操作部の双方がレバー型の操作部である場合に、双方が請求項４の適用を受ける「レバー型の操作部」であってもよいし、一方のみが請求項４の適用を受ける「レバー型の操作部」であってもよい。尚、請求項１〜請求項４の発明において、請求項４の適用を受けない「レバー型の操作部」を備える場合、当該操作部には、傾動操作及び回動操作のうちの一方のみを施すことが可能であってもよいし、傾動操作及び回動操作の双方を施すことが可能であってもよい。   In the first to fourth aspects of the invention, both the hot water side operation section and the hot water side operation section may be lever type operation sections, or only one of them may be a lever type operation section. . Further, when both the hot water side operation unit and the hot water side operation unit are lever type operation units, both of them may be “lever type operation units” to which the application of claim 4 is applied. Only one of them may be a “lever-type operation unit” that receives the application of claim 4. In addition, in the inventions of claims 1 to 4, when a “lever-type operation unit” that is not subject to the application of claim 4 is provided, the operation unit has only one of a tilt operation and a rotation operation. It may be possible to perform, or it may be possible to perform both a tilting operation and a rotating operation.

請求項５の水栓は、請求項１乃至請求項４の何れかに記載の水栓において、
前記レバー型の操作部が前記水栓の最上部に配置されていることを特徴とする。 The faucet according to claim 5 is the faucet according to any one of claims 1 to 4,
The lever-type operation part is arranged at the uppermost part of the faucet.

請求項５の発明によると、水栓の使用勝手が更に向上する。即ち、「レバー型の操作部」は、レバー形状を備えると共に、傾動操作や回動操作を操作態様するため、その上方や斜め上方から操作する構成とすれば、その操作性が特に向上する。この点に着目し、請求項５の発明では、レバー型の操作部を水栓の最上部に配置し、その操作性を更に向上させるため、水栓の使用勝手が更に向上する。   According to the invention of claim 5, the usability of the faucet is further improved. In other words, the “lever-type operation unit” has a lever shape and has a tilting operation and a rotating operation, so that the operability is particularly improved if the operation is performed from above or obliquely above. Focusing on this point, in the invention of claim 5, the lever-type operation part is arranged at the uppermost part of the faucet, and the operability thereof is further improved, so the usability of the faucet is further improved.

請求項６の水栓は、請求項３に記載の水栓において、
前記レバー型の操作部が前記水栓の最上部に配置されているとともに前記ハンドル型の操作部が前記水栓の側面部又は前面部のうちの一方に配置されていることを特徴とする。 The faucet of claim 6 is the faucet of claim 3,
The lever-type operation unit is disposed at the top of the faucet, and the handle-type operation unit is disposed on one of a side surface or a front surface of the faucet.

請求項６の発明によると、請求項５の発明と同様に、水栓の使用勝手が更に向上する。つまり、レバー型の操作部においては、前述のように、水栓の最上部に配置すると、その操作性が更に向上する。また、ハンドル型の操作部は、例えば、使用者がその全体をつかんで、回動させて操作するものである。このため、「ハンドル型の操作部を操作する使用者」にとっては、掌を側方に向けつつ、この操作部を操作可能であったり、この操作部を自己に近接する状態に配置しつつ、操作可能であれば、その操作性が更に高くなる。この点に着目し、請求項６の発明では、ハンドル型の操作部を水栓の側面部（掌を側方に向けて操作可能な位置）や、水栓の前面部（自己に近接する状態で操作可能な位置）に配置する。即ち、請求項６の発明を、レバー型の操作部及びハンドル型の操作部をより的確な位置に配置するため、水栓の使用勝手が更に向上する。   According to the invention of claim 6, as with the invention of claim 5, the usability of the faucet is further improved. That is, in the lever-type operation section, as described above, the operability is further improved if the lever-type operation section is arranged at the uppermost part of the faucet. Further, the handle-type operation unit is operated, for example, by the user grasping the whole and rotating it. For this reason, for the “user operating the handle type operation unit”, the operation unit can be operated while the palm is directed sideways, or the operation unit is arranged in a state close to the self, If it can be operated, the operability is further enhanced. Focusing on this point, in the invention of claim 6, the handle-type operation part is placed on the side part of the faucet (position where the palm can be operated sideways) or the front part of the faucet (the state close to self). To the position where it can be operated. That is, since the lever-type operation unit and the handle-type operation unit are arranged at more appropriate positions in the invention of claim 6, the usability of the faucet is further improved.

請求項７の水栓は、 湯を流入させる湯側の流入路と、水を流入させる水側の流入路と、吐水手段に繋がる流出路と、を具備する水栓本体を備える水栓であって、
前記水栓本体が、
湯側の操作部によって閉弁操作されると、前記湯側の流入路と前記流出路とを非連通な状態とし、該湯側の操作部によって開弁操作されると、前記湯側の流入路と前記流出路とを連通状態とする湯側の吐止水弁と、
水側の操作部によって閉弁操作されると、前記水側の流入路と前記流出路とを非連通な状態とし、該水側の操作部によって開弁操作されると、前記水側の流入路と前記流出路とを連通状態とする水側の吐止水弁と、を備え、
前記水栓本体の外部であって前記湯側の流入路の１次側の部位に、所定の調温手段を配置し、
前記調温手段によって予め所望温度に温度制御された湯が、前記湯側の流入路に流入することを特徴とする。 The faucet of claim 7 is a faucet provided with a faucet body comprising a hot water inflow passage through which hot water flows in, a water inflow passage through which water flows in, and an outflow passage connected to the water discharge means. And
The faucet body is
When the valve is operated to close by the hot water side operation section, the hot water side inflow path and the outflow path are not communicated, and when the hot water side operation section is operated to open the valve, A hot water-side water stop valve that connects the passage and the outflow passage;
When the water-side operation unit is closed, the water-side inflow path and the outflow path are disconnected from each other, and when the water-side operation unit is opened, the water-side inflow path A water-side water stop valve that makes the passage and the outflow passage communicate with each other,
A predetermined temperature control means is disposed outside the faucet body and on the primary side of the inflow channel on the hot water side,
Hot water whose temperature is controlled to a desired temperature in advance by the temperature adjusting means flows into the inflow passage on the hot water side.

請求項７の発明は、請求項２の発明と同様な趣旨でなされたものである。即ち、請求項７の発明においても、水栓本体の１次側で、所望温度に温度制御された「湯」を、湯側の流入路を通じて水栓本体に流入させる。よって、使用者は、調温手段から水栓本体に供給される湯の温度を予め所望温度に設定しておくだけで、より一層、使用勝手の良い状態にて水栓を使用することができる。   The invention of claim 7 is made for the same purpose as the invention of claim 2. That is, also in the invention of claim 7, “hot water” whose temperature is controlled to a desired temperature on the primary side of the faucet body is caused to flow into the faucet body through the inflow passage on the hot water side. Therefore, the user can use the faucet in a more convenient state only by setting the temperature of the hot water supplied from the temperature control means to the faucet body to a desired temperature in advance. .

また、請求項７の発明の水栓においても、その水栓本体の内部において、複雑な流路構造を備える弁装置を配置しないため、吐水手段から吐水される湯や水の吐水流量（勢い）を十分に確保できる。また、単一の操作部によって、温度調節用の操作と、吐止水用の操作とを行う構造でないため、前に行われた「操作」によってなされた設定が、後に行われる「他の操作」の際に誤って変更されることはない。また、「湯側の操作部」及び「水側の操作部」のうちの一方を操作したり、双方を操作すれば、吐止水の選択等を行うことができる。よって、請求項７の発明の水栓は、操作性が高く、使用勝手に優れる。   Further, in the faucet of the invention of claim 7, since a valve device having a complicated flow path structure is not arranged in the faucet body, the water discharge flow rate (momentum) of hot water or water discharged from the water discharge means Can be secured sufficiently. In addition, since there is no structure for performing the temperature adjustment operation and the spout water operation by a single operation unit, the setting made by the previous “operation” is performed after “other operation” Will not be changed accidentally. In addition, if one of the “hot water side operation unit” and the “water side operation unit” is operated or both of them are operated, it is possible to select the water to be discharged. Therefore, the faucet of the invention of claim 7 has high operability and excellent usability.

更に、請求項７の発明の水栓においても、その水栓本体の内部に、構造が複雑で、製造コストや設置スペースが嵩む部品を配置しない。このため、水栓の機構（構造）の簡略化と製造コストの低廉化を図ることが容易である。また、水栓本体のサイズや形状の選択の自由度が高くなるため、水栓のデザインの選択の自由度が高くなる。   Further, in the faucet of the invention of claim 7, a component having a complicated structure and increasing manufacturing cost and installation space is not arranged in the faucet body. For this reason, it is easy to simplify the faucet mechanism (structure) and reduce the manufacturing cost. Moreover, since the degree of freedom in selecting the size and shape of the faucet body is increased, the degree of freedom in selecting the faucet design is increased.

尚、請求項７の発明の水栓の使用態様としても、「湯側の操作部」のみに開放操作（開弁操作）を施し、湯側の流入路に流入する湯のみを吐水する使用態様と、「水側の操作部」のみを開放操作（開弁操作）を施し、水側の流入路に流入する水のみを吐水する使用態様とが特に好適である。これらの場合には、単一の操作部のみに施される「一操作」によって、吐止水の選択等を行うことができるため、水栓をより円滑に操作することができるからである。但し、請求項７の発明の水栓においても、「湯側の操作部」及び「水側の操作部」の双方に開放操作（開弁操作）を施し、湯側の流入路に流入する湯と、水側の流入路に流入する水とを、水栓本体の内部で混合した上で、吐水してもよい。   In addition, as a usage mode of the faucet of the invention of claim 7, a usage mode in which only the "hot water side operation section" is opened (valve opening operation) and only hot water flowing into the hot water side inflow passage is discharged. A use mode in which only the “water side operation portion” is subjected to an opening operation (valve opening operation) and only water flowing into the water side inflow passage is discharged is particularly preferable. In these cases, the water faucet can be operated more smoothly because selection of the water stoppage or the like can be performed by “one operation” performed only on a single operation unit. However, in the faucet of the invention of claim 7, the hot water flowing into the hot water side inflow passage is provided by performing an opening operation (valve opening operation) on both of the “hot water side operation portion” and the “water side operation portion”. The water flowing into the inflow channel on the water side may be discharged after being mixed inside the faucet body.

また、請求項７の発明の水栓では、「湯側の操作部」及び「水側の操作部」の態様は特に問わない。即ち、請求項１乃至請求項６の何れかの発明に示す態様の他に、湯側の操作部及び水側の操作部の双方を、「レバー型以外のタイプの操作部（例えば、ハンドル型の操作部）」とする態様も含まれる。   Further, in the faucet of the invention of claim 7, the modes of the “hot water side operation section” and the “water side operation section” are not particularly limited. That is, in addition to the aspect shown in any one of the inventions of claims 1 to 6, both the hot water side operation unit and the water side operation unit are provided with an operation unit of a type other than a lever type (for example, a handle type). The operation part) ”is also included.

請求項１〜請求項７の各発明において、「湯側の吐止水弁」及び「水側の吐水水弁」の構造、形式は種々選択できる。例えば、吐止水の選択のみを行うものであってもよいし、吐止水の選択及び吐水流量の調節を行うものや、吐止水の選択と吐水流量の調節に加えて流出路（吐水手段）の選択（切換）を行うものであってもよい。また、請求項１〜請求項７の各発明において、「湯側の吐止水弁」及び「水側の吐水水弁」の具体的構造としては、例えば、（Ａ）互いに平面摺動して、互いの流路の開閉や連通度合い等の調節を行う固定弁体及び可動弁体を備える平面摺動方式の吐止水弁、（Ｂ）対向する一対の弁口に対して弁体を進退させて流路の切換及び流量の調節を行うリフト方式の吐止水弁、（Ｃ）各々円筒状に成されると共に互いに挿嵌された固定弁体及び可動弁体を有し、互いに周面摺動して流路の開閉を行うロータリー方式の吐止水弁、（Ｄ）弁口と、この弁口方向に付勢されたボール状の弁体とを有し、弁体と弁口とを相対的に移動させて弁口の開閉を行うボール弁方式の吐止水弁、等を例示できる。また、請求項１〜請求項７の各発明の「吐水手段」としては、例えば、カランやシャワー等を例示できる。   In each of the first to seventh aspects of the present invention, the structures and types of the “hot water side water discharge valve” and the “water side water discharge water valve” can be variously selected. For example, it may be one that performs only selection of water discharge, one that performs selection of water discharge and adjustment of the water discharge flow rate, an outflow path (water discharge) in addition to selection of water discharge and adjustment of water discharge flow rate (Means) may be selected (switched). Moreover, in each invention of Claims 1-7, as a specific structure of "the hot water side water discharge valve" and "the water side water discharge water valve", for example, , A flat sliding type non-water valve having a fixed valve body and a movable valve body for opening and closing each other and adjusting the degree of communication, etc. (B) The valve body is advanced and retracted with respect to a pair of opposed valve ports. Lift type water stop valve for switching the flow path and adjusting the flow rate, and (C) each having a fixed valve body and a movable valve body which are each formed in a cylindrical shape and are fitted to each other. A rotary-type water stop valve that slides to open and close the flow path, (D) a valve port, and a ball-shaped valve body biased in the direction of the valve port, For example, a ball valve type water stop valve that opens and closes the valve port by relatively moving the valve opening and the like can be exemplified. In addition, examples of the “water discharge means” of each invention of claims 1 to 7 include a currant and a shower.

以上のように、本各発明によると、使用勝手が良く、構造の単純化を図ったり、製造コストの低廉化を図ることが容易で、デザインの選択の自由度が高い水栓が得られる。   As described above, according to the present invention, it is easy to use, it is easy to simplify the structure and to reduce the manufacturing cost, and a faucet having a high degree of freedom in design selection can be obtained.

That is, the fixed valve body 23 and the movable valve body 25 are in a state in which the inner peripheral surface of the fixed valve body 23 and the outer peripheral surface of the movable valve body 25 are slidable on the peripheral surface in a state where the axes are coaxially arranged. It is inserted.

湯側の吐止水弁２０は、上下方向への傾動操作と、左右方向への回動操作とが可能なレバー型の操作部（つまり、湯側の操作部）２６によって操作される。即ち、操作部２６に傾動操作を施すと、駆動軸２５ａ及び可動弁体２５が上下に駆動する。また、操作部２６に回動操作を施すと、駆動軸２５ａ及び可動弁体２５が回動する構成とされている。つまり、操作部２６を下方から上方に傾動すると、駆動軸２５ａ及び可動弁体２５が、それら（駆動軸２５ａ及び可動弁体２５）の軸心方向に沿って上昇する。また、操作部２６を上方から下方に傾動すると、駆動軸２５ａ及び可動弁体２５が、それら（駆動軸２５ａ及び可動弁体２５）の軸心方向に沿って下降する。更に、操作部２６に右回転操作を加えると、駆動軸２５ａ及び可動弁体２５が、それら（駆動軸２５ａ及び可動弁体２５）の軸心回りに右回転し、操作部２６に左回転操作を加えると、駆動軸２５ａ及び可動弁体２５が、それら（駆動軸２５ａ及び可動弁体２５）の軸心回りに左回転する構造となっている。   The hot water-side discharge water valve 20 is operated by a lever-type operation portion (that is, a hot water-side operation portion) 26 that can be tilted in the vertical direction and rotated in the left-right direction. That is, when the operation unit 26 is tilted, the drive shaft 25a and the movable valve body 25 are driven up and down. Further, when the operation unit 26 is turned, the drive shaft 25a and the movable valve body 25 are turned. That is, when the operation unit 26 is tilted from below to above, the drive shaft 25a and the movable valve body 25 are raised along the axial direction of them (the drive shaft 25a and the movable valve body 25). Further, when the operation unit 26 is tilted downward from above, the drive shaft 25a and the movable valve body 25 are lowered along the axial direction of them (the drive shaft 25a and the movable valve body 25). Further, when a right rotation operation is applied to the operation unit 26, the drive shaft 25a and the movable valve body 25 rotate right around the axis of the drive shaft 25a and the movable valve body 25, and the operation unit 26 performs a left rotation operation. Is added, the drive shaft 25a and the movable valve body 25 are structured to rotate counterclockwise around the axial centers of them (the drive shaft 25a and the movable valve body 25).

尚、操作部２６に施される操作（操作力）を、駆動軸２５ａ及び可動弁体２５に伝達するための「伝達手段」の具体的な構成は特に問わず、例えば、以下の具体例を例示できる。例えば、操作部２６の一端部２６ａに「略摩擦車状の部分（歯車状の部分でもよい。）」を設け、操作部２６（取っ手部２６ｂ）を、略摩擦車状の部分の軸心を支点として傾動可能とする。また、略摩擦車状の部分の周面と、駆動軸２５ａの周面との間に、駆動力伝達用の摩擦車２５ｂ（歯車若しくはピニオンであってもよい。また、ピニオン状の場合、駆動軸２５ａはラック状とされる。）を、圧接状に介在させる。そして、操作部２６を、略摩擦車状の部分を軸心に傾動させると、この「略摩擦車状の部分」に回転を生じ、この回転による回転力を摩擦車２５ｂを通じて駆動軸２５ａに伝達し、駆動軸２５ａを上下動させる。一方、操作部２６を左右に回動させると、摩擦車２５ｂと、駆動軸２５ａと、可動弁体２５とが一体で左右に回動する。また、この「伝達手段」をリンク機構等の他の機構によって構成することもできる。   The specific configuration of the “transmission means” for transmitting the operation (operation force) applied to the operation unit 26 to the drive shaft 25a and the movable valve body 25 is not particularly limited. It can be illustrated. For example, a "substantially friction wheel-like part (or a gear-like part)" is provided at one end 26a of the operation part 26, and the operation part 26 (the handle part 26b) is placed at the axial center of the substantially friction wheel-like part. It can be tilted as a fulcrum. Further, a friction wheel 25b for transmission of driving force (a gear or a pinion may be used) between the peripheral surface of the substantially friction wheel-shaped portion and the peripheral surface of the drive shaft 25a. The shaft 25a has a rack shape). When the operation portion 26 is tilted about the substantially friction wheel-shaped portion, the "substantially friction wheel-shaped portion" rotates, and the rotational force generated by this rotation is transmitted to the drive shaft 25a through the friction wheel 25b. Then, the drive shaft 25a is moved up and down. On the other hand, when the operation unit 26 is rotated left and right, the friction wheel 25b, the drive shaft 25a, and the movable valve body 25 are integrally rotated left and right. Further, the “transmission means” may be configured by other mechanisms such as a link mechanism.

可動弁体２５は、その内部空間を給湯流路２７とすると共に、周壁部２８に、可動側の湯出口２８ａを備えている。このうち、給湯流路２７は、その「１次側の端部」が前述の「湯取入口２１」と連続すると共に、「２次側の端部」が湯出口２８ａと連続している。また、可動側の湯出口２８ａは、周壁部２８の表裏を貫通する状態に設けられると共に、可動弁体２５の周方向に沿って長尺状となる略円弧形状を備えている。   The movable valve body 25 has a hot water supply passage 27 as its internal space, and a movable-side hot water outlet 28 a in the peripheral wall portion 28. Among these, the “primary side end” of the hot water supply channel 27 is continuous with the above-mentioned “hot water inlet 21”, and the “secondary side end” is continuous with the hot water outlet 28 a. Further, the movable-side hot water outlet 28 a is provided in a state of penetrating the front and back of the peripheral wall portion 28, and has a substantially arc shape that is elongated along the circumferential direction of the movable valve body 25.

固定弁体２３は、その内部空間を可動弁体２５の摺動空間とすると共に、周壁部２４に、固定側の湯出口２４ａを備えている。この固定側の湯出口２４ａも、周壁部２４の表裏を貫通すると共に、固定弁体２３の周方向に沿った略円弧形状に設けられている。但し、固定側の湯出口２４ａでは、前述の「可動側の湯出口２８ａ」に比べて、周壁部２４の周方向に沿った幅が小さくされている。また、固定側の湯出口２４ａは、その「２次側の端部」が、前述の「湯取出口２２」と連続している。   The fixed valve body 23 has an internal space as a sliding space for the movable valve body 25, and includes a fixed-side hot water outlet 24 a in the peripheral wall portion 24. The fixed-side hot water outlet 24 a also penetrates the front and back of the peripheral wall portion 24 and is provided in a substantially arc shape along the circumferential direction of the fixed valve body 23. However, in the fixed-side hot water outlet 24a, the width along the circumferential direction of the peripheral wall portion 24 is made smaller than that of the aforementioned “movable-side hot water outlet 28a”. Further, the “secondary side end” of the fixed-side hot water outlet 24 a is continuous with the “hot water outlet 22” described above.

この湯側の吐止水弁２０では、操作部２６（取っ手部２６ｂ）がその軸線を略水平に向けると、可動弁体２５は最下方に位置する。このとき、可動側の湯出口２８ａは、固定側の湯出口２４ａよりも下方に位置し、両湯出口２８ａ、２４ａは非連通な状態となる｛図３（ａ）参照｝。つまり、本実施例の水栓１０は、「湯側の吐止水弁２０に関する止水状態」となる。   In the hot water side stop water valve 20, when the operation part 26 (handle part 26b) orients the axis line substantially horizontally, the movable valve body 25 is located in the lowest part. At this time, the movable hot water outlet 28a is located below the fixed hot water outlet 24a, and the hot water outlets 28a and 24a are in a non-communication state {see FIG. 3 (a)}. That is, the faucet 10 of the present embodiment is in a “water-stopping state relating to the hot water-side water stop valve 20”.

また、操作部２６を上方に傾動すると、可動弁体２５が上昇する。そして、操作部２６の上方への傾動量が所定量となると、両湯出口２８ａ、２４ａが連通状態となる｛図３（ｂ）参照｝。このとき、湯側の流入路１５と流出路１７とが、湯取入口２１、給湯流路２７及び湯取出口２２を介して連通する。これにより、本実施例の水栓１０は、「湯側の吐止水弁２０に関する吐水状態」となる。尚、可動側の湯出口２８ａのうちで、固定側の湯出口２４ａによって解放される量、つまり、湯出口２８ａの解放量は、操作部２６の上方への傾動量によって決定される。つまり、この湯側の吐止水弁２０では、操作部２６（取っ手部２６ｂ）に加える上下への傾動操作が「本操作」を構成する。   Further, when the operation unit 26 is tilted upward, the movable valve body 25 is raised. Then, when the amount of tilting upward of the operation unit 26 reaches a predetermined amount, both hot water outlets 28a and 24a are in communication (see FIG. 3B). At this time, the hot water side inflow passage 15 and the outflow passage 17 communicate with each other via the hot water inlet 21, the hot water supply passage 27, and the hot water outlet 22. Thereby, the faucet 10 according to the present embodiment is in a “water discharge state related to the hot water-side water stop valve 20”. Of the movable-side hot water outlet 28a, the amount released by the fixed-side hot water outlet 24a, that is, the released amount of the hot water outlet 28a is determined by the upward tilting amount of the operation unit 26. In other words, in the hot water side stop water valve 20, the upward and downward tilting operation applied to the operation portion 26 (the handle portion 26 b) constitutes the “main operation”.

一方、操作部２６に回動操作（右回転操作や左回転操作）を施しても、水栓１０の吐止水状態に変化を生じさせない。つまり、この湯側の吐止水弁２０では、操作部２６（取っ手部２６ｂ）に加える左右への回動操作が「空操作」を構成する。具体的には、操作部２６の上下方向（傾動方向）に沿った位置が、両湯出口２８ａ、２４ａを連通させない位置（可動側の湯出口２８ａを、固定側の湯出口２４ａよりも下方に配置する位置）である場合は、操作部２６に回動操作（右回転操作や左回転操作）を施しても、両湯出口２８ａ、２４ａは非連通な状態を維持する。即ち、操作部２６の上下方向（傾動方向）に沿った位置が、水栓１０を止水状態にする位置であるときには、操作部２６に回動操作（右回転操作や左回転操作）を施しても、水栓１０は止水状態のままである。   On the other hand, even if a rotation operation (right rotation operation or left rotation operation) is performed on the operation unit 26, no change occurs in the water stoppage state of the faucet 10. In other words, in the hot water-side water stop valve 20, the left / right turning operation applied to the operation portion 26 (the handle portion 26b) constitutes an “empty operation”. Specifically, the position along the vertical direction (tilting direction) of the operation unit 26 is a position where the hot water outlets 28a and 24a are not communicated (the hot water outlet 28a on the movable side is below the hot water outlet 24a on the fixed side). In the case of the arrangement position, both hot water outlets 28a and 24a are maintained in a non-communication state even if the operation unit 26 is rotated (right rotation operation or left rotation operation). That is, when the position along the up-and-down direction (tilting direction) of the operation unit 26 is a position where the faucet 10 is stopped, a rotation operation (right rotation operation or left rotation operation) is performed on the operation unit 26. Even so, the faucet 10 remains in a water-stopped state.

また、操作部２６の上下方向（傾動方向）に沿った位置が、両湯出口２８ａ、２４ａを連通させる位置（可動側の湯出口２８ａを、固定側の湯出口２４ａよりも下方に配置する位置）である場合は、操作部２６に回動操作（右回転操作や左回転操作）を施しても、両湯出口２８ａ、２４ａは連通状態を維持する。しかも、可動側の湯出口２８ａが周壁部２６の周方向に沿って長尺状に設けられている。このため、操作部２６に回動操作を施して可動側の湯出口２８ａと固定側の湯出口２４ａとの周方向に沿った相対位置が変化しても、可動側の湯出口２８ａのうちで、固定側の湯出口２４ａによって解放される量、つまり、湯出口２８ａの解放量が変化しないようにされている。即ち、操作部２６の上下方向（傾動方向）に沿った位置が、水栓１０を吐水状態にする位置であるときには、操作部２６に回動操作（右回転操作や左回転操作）を施しても、水栓１０は吐水状態のままであるばかりか、吐水量も一定に保たれる。   Further, the position along the vertical direction (tilting direction) of the operation unit 26 is a position where the hot water outlets 28a and 24a communicate with each other (a position where the movable hot water outlet 28a is disposed below the fixed hot water outlet 24a). ), The hot water outlets 28a and 24a maintain the communication state even if the operation unit 26 is rotated (right rotation operation or left rotation operation). Moreover, the movable-side hot water outlet 28 a is provided in a long shape along the circumferential direction of the peripheral wall portion 26. For this reason, even if the relative position along the circumferential direction of the movable hot water outlet 28a and the fixed hot water outlet 24a is changed by rotating the operation portion 26, the movable hot water outlet 28a The amount released by the fixed-side hot water outlet 24a, that is, the released amount of the hot water outlet 28a is kept unchanged. That is, when the position along the vertical direction (tilting direction) of the operation unit 26 is a position where the faucet 10 is in a water discharge state, the operation unit 26 is rotated (right rotation operation or left rotation operation). However, the faucet 10 remains in the water discharge state, and the water discharge amount is also kept constant.

水側の吐止水弁３０は、吐止水の選択と吐水量の調節を行うための弁機構（図示を省略）を備えており、この弁機構は操作軸（例えば、スピンドル）３３を水栓本体１１の前方に突出させている（図１参照）。そして、この操作軸３３の突端には、ハンドル型の操作部（つまり、水側の操作部）３６が装着されている。この操作部３６は、操作軸３３を軸心とする回動操作のみを操作態様とするものである。そして、図２（ｂ）に示すように、操作部３６の取っ手部３６ａを上方に向けた状態とすると、水側の吐止水弁３０（弁機構）は閉弁駆動され、閉弁状態となる。このため、水側の流入路１６と、流出路１７とが非連通な状態となり、「水側の吐止水弁３０に関する水状態」となる。   The water-side stop water valve 30 includes a valve mechanism (not shown) for selecting the stop water and adjusting the water discharge amount. It protrudes in front of the plug body 11 (see FIG. 1). A handle-type operation unit (that is, a water-side operation unit) 36 is attached to the protruding end of the operation shaft 33. The operation unit 36 has only the rotation operation about the operation shaft 33 as an operation mode. Then, as shown in FIG. 2 (b), when the handle portion 36a of the operation portion 36 is directed upward, the water-side stop water valve 30 (valve mechanism) is driven to close, Become. For this reason, the inflow channel 16 on the water side and the outflow channel 17 are not in communication with each other, and the “water state relating to the water stop valve 30 on the water side” is established.

一方、操作部３６を右方向（左方向でもよい。）に回転させると、水側の吐止水弁３０（弁機構）は開弁駆動され、開弁状態となる。このため、水側の流入路１６と、流出路１７とが連通状態となり、「水側の吐止水弁３０に関する吐水状態」となる。   On the other hand, when the operation unit 36 is rotated rightward (or leftward), the water-side stop water valve 30 (valve mechanism) is driven to open, and the valve is opened. For this reason, the inflow path 16 on the water side and the outflow path 17 are in communication with each other, and the “water discharge state relating to the water-side stop valve 30” is established.

尚、流出路１７に流入する水の流量（水の吐水量）は、操作部３６を右回転方向（左回転方向でもよい。）への回転量（操作量）を増加させると、増加するように構成されている。また、本実施例では、水側の吐止水弁３０の具体的な構成の図示等を省略するが、例えば、平面摺動方式の吐止水弁、リフト方式の吐止水弁、ロータリー方式の吐止水弁、ボール弁方式の吐止水弁等の種々の弁装置を例示することができる。   It should be noted that the flow rate of water flowing into the outflow passage 17 (the amount of water discharged) increases as the amount of rotation (operation amount) of the operation unit 36 in the right rotation direction (or the left rotation direction) may be increased. It is configured. Further, in this embodiment, illustration of a specific configuration of the water-side stop water valve 30 is omitted, but for example, a flat-slide-type stop water valve, a lift-type stop water valve, and a rotary system Various valve devices such as a water stop valve and a ball valve type water stop valve can be exemplified.

次に、図１〜図５を用いて、本水栓設備Ｓの使用例を簡単に説明する。先ず、図１及び図２に示すように、両操作部２６、３６が止水位置にあると、両吐止水弁２０、３０内の弁機構は止水状態とされる。このため、給湯用の元配管部１Ａから供給される湯が、湯側の吐止水弁２０の２次側（流出路１７）に流出できないと共に、給水用の元配管部１Ｂから供給される水が、水側の吐止水弁３０の２次側（流出路１７）に流出できないため、本水栓１０全体が止水状態となる。   Next, the usage example of this water faucet equipment S is demonstrated easily using FIGS. First, as shown in FIG.1 and FIG.2, when both the operation parts 26 and 36 exist in a water stop position, the valve mechanism in both the water discharge valves 20 and 30 will be in a water stop state. For this reason, the hot water supplied from the hot water supply main piping section 1A cannot flow out to the secondary side (outflow passage 17) of the hot water side discharge water valve 20, and is supplied from the main water supply piping section 1B. Since water cannot flow out to the secondary side (outflow passage 17) of the water-side water stop valve 30, the water faucet 10 as a whole is stopped.

本実施例において、「給湯用の元配管部１Ａから供給される湯のみを吐水する場合（以下、「湯吐水」という。）」には、湯側の吐止水弁２０のみを開弁状態とし、水側の吐止水弁３０を閉弁状態のままとする。   In the present embodiment, when “only hot water supplied from the hot water supply original piping section 1A is discharged (hereinafter referred to as“ hot water discharge ”)”, only the hot water side stop water valve 20 is opened. The water-side water stop valve 30 is kept closed.

具体的には、水栓１０を正面に見る使用者Ａが、湯吐水を行う場合｛図４（ａ）参照｝、この使用者Ａは、湯側の操作部２６を上方に傾動操作する。これにより、駆動軸２５ａと共に可動弁体２５が上昇し、可動側の湯出口２８ａが固定側の湯出口２４ａと連通し、湯側の流入路１５と流出路１７とが、湯取入口２１、給湯流路２７及び湯取出口２２を介して連通する｛図３及び図４（ｂ）参照｝。よって、給湯用の元配管部１Ａから水栓本体１０に供給された湯が、吐水手段４０（カラン）を通じて吐水される。そして、この「湯吐水」の際の吐水量は、操作部２６の上方への傾動量によって決定される。一方、水栓１０の正面Ａに位置する使用者Ａが、湯吐水を取り止める場合には、湯側の操作部２６を下方に傾動操作すればよい。   Specifically, when the user A who looks at the faucet 10 performs hot water discharge (see FIG. 4A), the user A tilts the hot water-side operation unit 26 upward. As a result, the movable valve body 25 rises together with the drive shaft 25a, the movable hot water outlet 28a communicates with the fixed hot water outlet 24a, and the hot water inlet 15 and outlet 17 are connected to the hot water inlet 21, It communicates via the hot water supply flow path 27 and the hot water outlet 22 (see FIG. 3 and FIG. 4B). Therefore, the hot water supplied to the faucet body 10 from the main piping part 1A for hot water supply is discharged through the water discharging means 40 (curan). The amount of water discharged during the “hot water discharge” is determined by the upward tilt amount of the operation unit 26. On the other hand, when the user A located on the front surface A of the faucet 10 stops the hot water discharge, the hot water operation section 26 may be tilted downward.

水栓１０を左斜め前方に見る使用者Ｂが、湯吐水を行う場合｛図５（ａ）参照｝、この使用者Ｂは、湯側の操作部２６を自己の正面に回動させた後に、この湯側の操作部２６を上方に傾動操作する。これにより、駆動軸２５ａと共に可動弁体２５が上昇し、可動側の湯出口２８ａが固定側の湯出口２４ａと連通し、湯側の流入路１５と流出路１７とが、湯取入口２１、給湯流路２７及び湯取出口２２を介して連通し｛図５（ｂ）参照｝、給湯用の元配管部１Ａから水栓本体１０に供給された湯が、吐水手段４０（カラン）を通じて吐水される。一方、この使用者Ｂが、湯吐水を取り止める場合には、湯側の操作部２６を下方に傾動操作すればよい。   When the user B who sees the faucet 10 diagonally to the left performs hot water discharge (see FIG. 5A), the user B turns the hot water-side operation unit 26 to the front of the user B. Then, the hot water side operation section 26 is tilted upward. As a result, the movable valve body 25 rises together with the drive shaft 25a, the movable hot water outlet 28a communicates with the fixed hot water outlet 24a, and the hot water inlet 15 and outlet 17 are connected to the hot water inlet 21, The hot water supplied to the faucet body 10 from the main pipe portion 1A for hot water supply is discharged through the water discharge means 40 (curan) through the hot water supply passage 27 and the hot water outlet 22 (see FIG. 5B). Is done. On the other hand, when the user B stops the hot water discharge, the hot water side operation unit 26 may be tilted downward.

水栓１０を右斜め前方に見る使用者Ｃが、湯吐水を行う場合、この使用者Ｃは、湯側の操作部２６を自己の正面に回動させた後に、この湯側の操作部２６を上方に傾動操作する。これにより、駆動軸２５ａと共に可動弁体２５が上昇し、可動側の湯出口２８ａが固定側の湯出口２４ａと連通し、湯側の流入路１５と流出路１７とが、湯取入口２１、給湯流路２７及び湯取出口２２を介して連通し｛図５（ｃ）参照｝、給湯用の元配管部１Ａから水栓本体１０に供給された湯が、吐水手段４０（カラン）を通じて吐水される。一方、この使用者Ｃが、湯吐水を取り止める場合には、湯側の操作部２６を下方に傾動操作すればよい。   When the user C who sees the faucet 10 diagonally right forward performs hot water discharge, the user C rotates the hot water-side operation unit 26 in front of the user, and then the hot water-side operation unit 26. Is tilted upward. As a result, the movable valve body 25 rises together with the drive shaft 25a, the movable hot water outlet 28a communicates with the fixed hot water outlet 24a, and the hot water inlet 15 and outlet 17 are connected to the hot water inlet 21, The hot water supplied to the faucet body 10 from the main pipe portion 1A for hot water supply is discharged through the water discharge means 40 (curan) through the hot water supply passage 27 and the hot water outlet 22 (see FIG. 5C). Is done. On the other hand, when the user C stops hot water discharge, the hot water side operation unit 26 may be tilted downward.

このように、本実施例では、湯側の操作部２６が左右の回転方向（回動方向）に振り角（遊び角）を有する。このため、使用者が水栓１０の正面に位置しない場合（斜め前方や、側方等に位置する場合）にも、この使用者は、湯側の操作部２６を自己の正面に向けたり、自己により近接する位置に移動することができる。つまり、本水栓１０は、その使用状況に応じて、湯側の操作部２６の位置を変更し、吐止水操作や吐水量の選択操作を行うことができる。   As described above, in the present embodiment, the operation unit 26 on the hot water side has a swing angle (play angle) in the left and right rotation direction (rotation direction). For this reason, even when the user is not located in front of the faucet 10 (when obliquely forward or laterally), the user can point the hot water-side operation unit 26 toward his / her own front, You can move closer to yourself. In other words, the water faucet 10 can change the position of the hot water-side operation unit 26 according to the usage state, and perform a water discharge operation and a water discharge amount selection operation.

本実施例において、「給水用の元配管部１Ｂから供給される水のみを吐水する場合（以下、「水吐水」という。）」には、水側の吐止水弁３０のみを開弁状態とし、湯側の吐止水弁２０を閉弁状態のままとする。つまり、止水位置にある水側の操作部３６を、右回転方向に回転させると｛図２（ｂ）参照｝、水側の吐止水弁３０（弁機構）は開弁駆動され、開弁状態となる。このため、水側の流入路１６と、流出路１７とが連通状態となり、水吐水が開始される。一方、この状態から水吐水を取り止める場合には、吐水位置にある水側の操作部３６を、左回転方向に回転させ、水側の吐止水弁３０（弁機構）を閉開弁駆動し、閉弁状態とすればよい。尚、流出路１７に流入する水の流量（水の吐水量）は、操作部３６の右方向への回転量（回動量）に応じて定められる。   In the present embodiment, when “only water supplied from the original water supply pipe section 1B is discharged (hereinafter referred to as“ water discharge ”)”, only the water-side stop valve 30 is opened. And the hot water-side water stop valve 20 remains closed. That is, when the water-side operation unit 36 in the water stop position is rotated in the clockwise direction (see FIG. 2B), the water-side stop water valve 30 (valve mechanism) is driven to open and open. It becomes a valve state. For this reason, the inflow path 16 on the water side and the outflow path 17 are in communication with each other, and water spouting is started. On the other hand, when water discharge is stopped from this state, the water-side operation unit 36 at the water discharge position is rotated in the counterclockwise direction, and the water-side discharge valve 30 (valve mechanism) is driven to open and close. The valve may be closed. The flow rate of water flowing into the outflow passage 17 (water discharge amount) is determined according to the amount of rotation (rotation amount) of the operation unit 36 in the right direction.

本実施例において、給湯用の元配管部１Ａから供給される湯と、給水用の元配管部１Ｂから供給される水との混合水（以下、単に「混合水」という。）を吐水させたい場合には、湯側の操作部２６及び水側の操作部３２の双方を、止水位置から吐水位置に操作すればよい。この場合、湯側の流入路１５に流入し、湯側の吐止水弁２０を通過した湯と、水側の流入路１６に流入し、水側の吐止水弁３０を通過した水とが、流出路１７に流入し、混合されて混合水となる。このとき、「湯」と「水」の混合比率は、湯側の操作部２６の上方への傾動操作量と、水側の操作部３６の右回転方向への回転操作量との比に応じて選択され、これにより、「湯」と「水」とを混合して構成される湯水の温度が選択される。但し、本実施例では、給湯用の元配管部１Ａから供給される湯の温度は、調温手段によって所望温度に制御されているため、このように、湯水を混合する必要性は乏しい。   In the present embodiment, it is desired to discharge water (hereinafter, simply referred to as “mixed water”) of hot water supplied from the hot water supply original piping portion 1A and water supplied from the water supply original piping portion 1B. In this case, both the hot water side operation unit 26 and the water side operation unit 32 may be operated from the water stop position to the water discharge position. In this case, the hot water that has flowed into the hot water side inflow passage 15 and passed through the hot water side water stop valve 20, the water that has flowed into the water side inflow passage 16 and passed through the water side water stop valve 30, However, it flows into the outflow passage 17 and is mixed to become mixed water. At this time, the mixing ratio of “hot water” and “water” depends on the ratio of the upward tilting operation amount of the hot water side operation unit 26 and the rotation operation amount of the water side operation unit 36 in the clockwise rotation direction. Thus, the temperature of hot water configured by mixing “hot water” and “water” is selected. However, in the present embodiment, the temperature of the hot water supplied from the hot water supply original piping section 1A is controlled to a desired temperature by the temperature control means, and thus there is little need to mix hot water.

以上のように、本実施例の水栓１０では、水栓本体１１に流入した湯の給湯圧や水栓本体１１に流入した水の給水圧を徒に低下させる機構を、水栓本体１１内に配置しない構造を備える。つまり、その水栓本体１１の内部において、複雑な流路構造を備える弁装置を配置しないため、吐水手段（カラン）４０から吐水される湯や水の吐水流量（勢い）を十分に確保できる。   As described above, in the faucet 10 of the present embodiment, a mechanism for reducing the hot water supply pressure of the hot water flowing into the faucet body 11 and the water supply pressure of the water flowing into the faucet main body 11 is provided in the faucet main body 11. It has a structure that is not arranged in That is, since a valve device having a complicated flow path structure is not arranged in the faucet body 11, a water discharge flow rate (momentum) of hot water or water discharged from the water discharge means (calant) 40 can be sufficiently secured.

また、湯側の操作部２６が、操作性の高い「レバー型の操作部」によって構成される。しかも、単一の操作部によって、温度調節用の操作と、吐止水用の操作とを行う構造でないため、前に行われた「操作」によってなされた設定が、後に行われる「他の操作」の際に誤って変更されることはない。よって、本実施例の水栓１０によると、従来の「レバー型の操作部」を備える水栓の長所を生かしつつ、短所を無くすことができる。つまり、「操作部（レバー型）の操作性の高い」という長所を生かしつつ、「意図しない設定変更を生じ易い」という短所を無くすことができる。   Further, the hot water side operation unit 26 is constituted by a “lever type operation unit” with high operability. In addition, since the temperature control operation and the spout water operation are not performed by a single operation unit, the setting made by the previous “operation” is set to “other operation”. Will not be changed accidentally. Therefore, according to the faucet 10 of the present embodiment, the disadvantages can be eliminated while taking advantage of the faucets provided with the conventional “lever-type operation section”. That is, while taking advantage of the “operability of the operation unit (lever type) is high”, it is possible to eliminate the disadvantage that “unintended setting change is likely to occur”.

また、本実施例の水栓１０では、「湯側の操作部２６」及び「水側の操作部３６」のうちの一方を操作したり、双方を操作すれば、吐止水の選択等を行うことができる。   Further, in the faucet 10 of the present embodiment, if one of the “hot water side operation unit 26” and the “water side operation unit 36” is operated or both are operated, the selection of the discharge water is performed. It can be carried out.

よって、本実施例の水栓１０は、操作性が高く、使用勝手に優れる。また、本実施例の水栓１０は、湯側の操作部（レバー型の操作部）２６を水栓１０（水栓本体１１）の最上部に配置し、水側の操作部（ハンドル型の操作部）３６を水栓１０（水栓本体１１）の前面部に配置するため、水栓１０の使用勝手が更に向上している。更に、本実施例の水栓１０では、その水栓本体１１の内部に、構造が複雑で、製造コストや設置スペースが嵩む部品を配置しないため、水栓１０の機構（構造）の簡略化と製造コストの低廉化を図ることが容易である。更に、水栓本体１１のサイズや形状の選択の自由度が高くなるため、水栓１０のデザインの選択の自由度が高くなる。   Therefore, the faucet 10 of this embodiment has high operability and excellent usability. Further, the faucet 10 of the present embodiment has a hot water side operation part (lever type operation part) 26 disposed at the top of the water faucet 10 (water faucet body 11), and a water side operation part (handle type operation part). Since the operation portion 36 is disposed on the front surface of the faucet 10 (the faucet body 11), the usability of the faucet 10 is further improved. Furthermore, in the faucet 10 of the present embodiment, the structure (structure) of the faucet 10 is simplified because the faucet body 11 does not include components having a complicated structure and a large manufacturing cost and installation space. It is easy to reduce the manufacturing cost. Furthermore, since the degree of freedom in selecting the size and shape of the faucet body 11 is increased, the degree of freedom in selecting the design of the faucet 10 is increased.

また、本実施例の水栓１０によると、使用者は、調温手段（給湯器５１）から水栓本体１１に供給される湯の温度を予め所望温度に設定しておくだけで、より一層、使用勝手の良い状態にて水栓１０を使用することができる。例えば、湯を吐水させたい場合（風呂への給湯時、洗髪時、手荒い時、食器洗浄時等）には、「湯側の操作部２６」のみに開放操作（開弁操作）を施せば足り、水を吐水させたい場合（清掃時等）には、「水側の操作部３６」のみに開放操作（開弁操作）を施せば足りる。つまり、湯側だけ、又は、水側だけの吐水（通水）を行う場合には、一方の操作部２６，３６に一操作を施せば足りることになる。換言すると、本水栓１０のサイドでは、温度調節操作を行わずに、水栓１０を使用することもできる。   Further, according to the faucet 10 of the present embodiment, the user can set the temperature of the hot water supplied from the temperature control means (the water heater 51) to the faucet body 11 in advance to a desired temperature. The faucet 10 can be used in an easy-to-use state. For example, if you want to discharge hot water (when supplying water to the bath, washing your hair, rough hands, washing dishes, etc.), it is sufficient to perform the opening operation (valve opening operation) only on the "hot water side operation unit 26". When it is desired to discharge water (for cleaning, etc.), it is sufficient to perform an opening operation (valve opening operation) only on the “water-side operation unit 36”. That is, when performing water discharge (water flow) only on the hot water side or only on the water side, it is sufficient to perform one operation on one of the operation units 26 and 36. In other words, the faucet 10 can be used on the side of the faucet 10 without performing the temperature adjustment operation.

更に、本実施例の水栓１０では、２つの操作部２６，３６の操作性に、意図的な差異を設けている。つまり、使用頻度の高い「湯側の操作部２６」の操作性をより高くし、使用勝手を更に向上させた水栓１０、即ち、「使用頻度の高い、湯側の吐止水を優先し、使用勝手を更に向上させた水栓１０を得ることができる。また、本実施例の水栓１０では、傾動操作を本操作とし、回動操作を空操作とするため、使用者と水栓１０との相対的な位置に関係無く、同様な使用性を確保できる。つまり、左右の回動方向（上下の傾動方向）に振り角（遊び角）を持つため、様々な使用状況に対し、使用勝手が良い水栓１０となる。   Furthermore, in the faucet 10 of the present embodiment, an intentional difference is provided in the operability of the two operation portions 26 and 36. That is, the operability of the "hot water side operation unit 26" that is frequently used is further enhanced, and the faucet 10 that is further improved in usability, that is, "frequently used hot water side spout water is given priority. The faucet 10 can be obtained with further improved usability, and the faucet 10 of the present embodiment has the tilting operation as the main operation and the turning operation as the empty operation, so that the user and the faucet can be obtained. The same usability can be secured regardless of the relative position with respect to 10. In other words, since there is a swing angle (play angle) in the left and right rotation direction (up and down tilt direction), The faucet 10 is easy to use.

尚、本各発明の範囲は前記各実施例に示す具体的な態様に限定されず、本各発明の範囲内で種々の変形例を例示できる。   The scope of each invention is not limited to the specific modes shown in the above embodiments, and various modifications can be exemplified within the scope of each invention.

For example, when the lever-type operation unit (either the hot water-side operation unit 26 or the water-side operation unit 36, or both of them) is tilted up and down, the selection of the water stoppage is performed as in the embodiment. Adjust the amount of water discharged. On the other hand, when the operation unit is rotated in either the left or right direction, water discharge from the first water discharge means (for example, currant) is selected, and when the operation unit is rotated in the left or right direction, the second The aspect by which the water discharge from a water discharge means (for example, shower) is selected can be illustrated.

尚、この変形例２においては、水栓本体１１の内部に複数の流出路が形成される。そして、吐止水弁（湯側の吐止水弁２０及び水側の吐止水弁３０のうちの一方、若しくは、双方）には、流出路に対応する数の流出口が設けられ、各流出口が各流出路に接続される。そして、吐止水弁によって、吐水に使用する流出路が選択される。   In the second modification, a plurality of outflow passages are formed inside the faucet body 11. And in the water stop valve (one of the hot water side stop water valve 20 and the water side stop water valve 30 or both), the number of outlets corresponding to the outflow path is provided, An outlet is connected to each outflow channel. And the outflow path used for water discharge is selected by the water discharge valve.

また、本実施例では、水栓本体１１の内部において、給湯用の元配管部１Ａから供給される湯と、給水用の元配管部１Ｂから供給される水とを混合可能な態様を例示したが、本各発明の水栓は、このような混合を行わないものであってもよい。例えば、請求項１〜請求項７の発明の水栓やその周囲に、以下のような禁止手段を設けてもよい。（Ａ）「湯側の吐止水弁の操作部」及び「水側の吐止水の操作部」の一方に開放操作（開弁操作）が施されたときに、他方に開放操作（開弁操作）が施されることを禁止する禁止手段、（Ｂ）「湯側の吐止水の操作部」に開放操作（開弁操作）が施されたときに、水側の流入路に水が流入することを禁止し、「水側の吐止水弁の操作部」に開放操作（開弁操作）が施されたときに、湯側の流入路に湯が流入することを禁止する禁止手段、（Ｃ）「湯側の吐止水弁の操作部」に開放操作（開弁操作）が施されたときに、水側の流入路に流入した水が「水側の吐止水弁」の２次側に流出することを禁止し、「水側の吐止水弁の操作部」に開放操作（開弁操作）が施されたときに、湯側の流入路に流入した湯が「湯側の吐止水弁」の２次側に流出することを禁止する禁止手段、等を設ける態様を例示できる。   Moreover, in the present Example, the aspect which can mix the hot water supplied from the main piping part 1A for hot water supply and the water supplied from the main piping part 1B for water supply inside the faucet main body 11 was illustrated. However, the faucets of the present inventions may not perform such mixing. For example, the following prohibition means may be provided around the faucet of the inventions of claims 1 to 7 and the periphery thereof. (A) When an opening operation (opening operation) is performed on one of the “operating section of the hot water side blocking water valve” and the “operating section of the water side blocking water”, the opening operation (opening) is performed on the other side. Prohibiting means for prohibiting the valve operation), (B) When the opening operation (opening operation) is performed on the "water-side water stop operation section", water is introduced into the water-side inflow passage. Prohibition of inflow of water and prohibition of hot water from flowing into the hot water inflow passage when the "operation part of the water-side discharge valve" is opened (opening operation) Means, (C) When the opening operation (opening operation) is performed on the “operating portion of the hot water-side stop water valve”, the water flowing into the water-side inflow passage is “the water-side stop water valve”. ”Is prohibited from flowing out to the secondary side, and when the opening operation (opening operation) is performed on the“ operation part of the water-side stop water valve ”, Outflows to the secondary side of the “water stop valve” The exemplified embodiment to provide a prohibiting means, such as to prohibit the.
