Description

本発明は、混合水栓に用いられる分岐栓の技術に関する。   The present invention relates to a technology of a branch plug used for a mixing faucet.

従来、湯側流路および水側流路にそれぞれ連通される横孔が形成される、分岐栓本体と、分岐栓本体をその内部に設ける筒状の外装部材と、分岐流路が形成される分岐接続部材と、を具備し、混合水栓の構成部材である混合水栓本体とカートリッジとの間に配置される、分岐栓に関する技術は公知となっている。例えば特許文献1に示す如くである。   Conventionally, a branch plug body in which a lateral hole communicating with each of the hot water channel and the water channel is formed, a cylindrical exterior member in which the branch plug body is provided, and a branch channel are formed. A technology relating to a branch plug, which is provided between the main body of the mixed water faucet and the cartridge, which is a component of the mixed water faucet, is well known. For example, as shown in Patent Document 1.

また、このような分岐栓においては、分岐栓本体の外周面に、分岐栓本体に形成された横孔と連通する横溝が形成されている。外装部材には、内周面から外周面にむけて貫通する貫通孔が前記横溝と連通するように形成されている。前記外装部材における貫通孔の外周面側の開口部分と分岐接続部材の一端部とが接続されている。そして、混合水栓本体から分岐栓に流入された湯または水は、分岐栓本体に形成された横孔および横溝を介して、分岐接続部材に形成された分岐流路から流出される。   In such a branch plug, a lateral groove communicating with a lateral hole formed in the branch plug main body is formed on the outer peripheral surface of the branch plug main body. The exterior member is formed with a through hole penetrating from the inner peripheral surface to the outer peripheral surface so as to communicate with the lateral groove. An opening portion on the outer peripheral surface side of the through hole in the exterior member and one end portion of the branch connection member are connected. Then, the hot water or water that has flowed into the branch plug from the mixed water faucet body flows out from the branch flow path formed in the branch connection member through the lateral hole and the lateral groove formed in the branch plug body.

もっとも、分岐栓本体に形成された横溝の上下には、各々Oリング等のシール部材(以下、シール部材と称する)が設けられており、当該シール部材によって分岐栓本体と外装部材との間の水密性、即ち、分岐栓の水密性が確保されている。なお、分岐栓本体に形成された横溝の上下には、位置決め溝が各々形成され、当該位置決め溝によって、分岐栓本体の所定の位置にシール部材が配置されている。
特開平10−231940号公報
However, seal members such as O-rings (hereinafter referred to as seal members) are respectively provided above and below the lateral groove formed in the branch plug body, and the seal member between the branch plug body and the exterior member is provided by the seal member. Watertightness, that is, watertightness of the branch plug is ensured. A positioning groove is formed above and below the lateral groove formed in the branch plug body, and a seal member is disposed at a predetermined position of the branch plug body by the positioning groove.
JP-A-10-231940

しかしながら、外装部材内に分岐栓本体を設ける際に、前記位置決め溝からシール部材が脱落する場合がある。そして、当該位置決め溝から脱落した前記シール部材は、分岐栓本体と外装部材とに挟まれて切断されること等によって、容易に破損してしまう。つまり、分岐栓本体の外周面にシール部材が設けられるような構成では、当該分岐栓本体を具備する分岐栓の水密性を確保するために、外装部材内に分岐栓本体を嵌装する作業には熟練が必要とされ、さらに作業を慎重に行う必要があった。   However, when the branch plug body is provided in the exterior member, the seal member may drop from the positioning groove. And the said sealing member which fell from the said positioning groove will be easily damaged by being pinched | interposed into a branch plug main body and an exterior member, and cut | disconnected. That is, in a configuration in which a seal member is provided on the outer peripheral surface of the branch plug body, in order to secure the water tightness of the branch plug having the branch plug body, the work of fitting the branch plug body into the exterior member is performed. The skill required skill and the work needed to be done carefully.

また、分岐栓本体に形成された横溝の上下にシール部材を設けるためには、当該シール部材を配置するためのスペースを確保すべく、分岐栓本体の軸心方向の長さを長く構成する必要がある。一方、台所の限られたスペース内では、混合水栓本体とカートリッジとの間に分岐栓を配置することができない場合がある。例えば、混合水栓の上方に自動昇降棚が配置されている台所の構成があるが、当該自動昇降棚の下降時に、自動昇降棚の低部と水栓の上部とが接触するような場合である。また、カウンター台が混合水栓の上方にまで延出しているような場合である。つまり、このような場合においても、混合水栓本体とカートリッジ本体との間に分岐栓を配置することができるように、分岐栓の軸心方向の長さは短く構成されることが望ましい。   Further, in order to provide the seal member above and below the lateral groove formed in the branch plug body, it is necessary to configure the length of the branch plug body in the axial direction in order to secure a space for arranging the seal member. There is. On the other hand, in a limited space of the kitchen, there may be a case where a branch plug cannot be disposed between the mixing faucet body and the cartridge. For example, there is a kitchen configuration in which an automatic lifting shelf is arranged above the mixing faucet, but when the automatic lifting shelf is lowered, the lower part of the automatic lifting shelf and the upper part of the faucet come into contact with each other. is there. Moreover, it is a case where the counter stand extends even above the mixing faucet. That is, even in such a case, it is desirable that the length of the branch plug in the axial direction is short so that the branch plug can be disposed between the mixing faucet body and the cartridge body.

本発明は以上の如き状況を鑑みて成されたものであり、分岐栓の水密性を確実に確保すること、および、分岐栓の軸心方向の長さを短く構成することを課題とする。   The present invention has been made in view of the circumstances as described above, and it is an object of the present invention to ensure the watertightness of the branch plug and to reduce the length of the branch plug in the axial direction.

The branch plug 1A is configured by combining the branch plug main body 10A, the exterior member 20A, and the first branch connection member 30 configured as described above. Below, the procedure of the said combination is demonstrated concretely.
The clonut 22 is covered from above the branch plug body 10A, and the branch plug body 10A and the owl nut 22 are fitted.
Then, the exterior main body 21A is covered from above the branch plug body 10A in such a state, and the branch body 10A and the exterior body 21A are fitted. In this case, both are fitted in a state in which the position of the first opening 15 provided in the branch plug body 10A and the position of the first through hole 25 formed in the exterior body 21A are matched.
Further, the insertion portion 31 that is one end of the first branch connection member 30 is inserted into the first through hole 25, and the insertion portion 31 of the first branch connection member 30 and the first opening 15 are directly joined. The insertion portion 31 of the first branch connection member 30 and the first opening 15 are joined by a male screw formed in the first branch connection member 30 and a female screw formed in the lateral hole 14A in the branch plug body 10A. By screwing together. In this case, a space between the male screw of the first branch connection member 30 and the female screw of the lateral hole 14A is sealed in a watertight manner by interposing a sealing material such as an adhesive.
In this way, the branch plug 1A is constituted by the branch plug main body 10A, the exterior member 20A, and the first branch connection member 30.

分岐栓1Aは、混合水栓本体2とカートリッジ3との間に配置される。以下において、混合水栓本体2とカートリッジ3との間に分岐栓1Aを配置する際の手順について具体的に説明する。
まず、混合水栓本体2の上に分岐栓1Aを載置する。この際、混合水栓本体2内に設けられた前記湯側流路管と分岐栓本体10Aに形成された湯側流路12との位置を、混合水栓本体2内に設けられた前記水側流路管と分岐栓本体10Aに形成された水側流路11との位置を、および、混合水栓本体2内に設けられた前記混合液流路管と分岐栓本体10Aに形成された戻り流路13との位置を、それぞれ一致させるようにして、混合水栓本体2の上に分岐栓1Aを載置する。斯るように混合水栓本体2の上に分岐栓1Aを載置することで、前期湯側流路管と湯側流路12とが、前記水側流路管と水側流路11とが、および、前記混合液流路管と戻り流路13とが、それぞれ連通されることとなる。
次に、フクロナット22を分岐栓本体10Aに対して回転してフクロナット22における下部の内周面に形成された雌ネジと、混合水栓本体2の上部に形成された雄ネジとを螺合さていく。当該雌ネジと雄ネジとを螺合させることにより、分岐栓本体10Aに形成された突部17と、フクロナット22に形成された突部23とが係合され、分岐栓1Aは、下方に押圧され混合水栓本体2に固定されることとなる。
そして、当該岐栓1Aの上方に、カートリッジ3を載置し、さらにハンドルレバー5が取り付けられたカバーナット4をカートリッジ3にかぶせて、カバーナット4を外装本体21Aの上端部に螺合することで、分岐栓1Aが混合水栓70に装着される。
The branch plug 1 </ b> A is disposed between the mixed water faucet body 2 and the cartridge 3. Below, the procedure at the time of arrange | positioning the branch plug 1A between the mixing faucet main body 2 and the cartridge 3 is demonstrated concretely.
First, the branch plug 1 </ b> A is placed on the mixing faucet body 2. At this time, the position of the hot water side flow pipe provided in the mixing faucet body 2 and the hot water side flow path 12 formed in the branch plug main body 10A is set to the position of the water provided in the mixing faucet main body 2. The positions of the side channel pipe and the water side channel 11 formed in the branch plug body 10A, and the mixed solution channel pipe and the branch plug body 10A provided in the mixed tap body 2 were formed. The branch plug 1 </ b> A is placed on the mixed water faucet body 2 so that the positions of the return flow paths 13 coincide with each other. In this way, by placing the branch plug 1A on the mixing faucet body 2, the previous hot water side flow channel pipe and the hot water side flow channel 12 are connected to the water side flow channel pipe and the water side flow channel 11, respectively. However, the mixed liquid channel tube and the return channel 13 are communicated with each other.
Next, the owl nut 22 is rotated with respect to the branch plug body 10A, and the female screw formed on the inner peripheral surface of the lower part of the owl nut 22 and the male screw formed on the upper part of the mixed water faucet body 2 are screwed together. Go. By engaging the female screw and the male screw, the protrusion 17 formed on the branch plug body 10A and the protrusion 23 formed on the owl nut 22 are engaged, and the branch plug 1A is pressed downward. Then, it is fixed to the mixing faucet body 2.
Then, the cartridge 3 is placed above the bifurcated plug 1A, and the cover nut 4 to which the handle lever 5 is attached is placed on the cartridge 3, and the cover nut 4 is screwed to the upper end portion of the exterior body 21A. Thus, the branch plug 1 </ b> A is attached to the mixing tap 70.

以上のようにして、分岐栓1Aにおいては、分岐栓本体10Aは外装部材20A内に設けられる。そして、斯る状態において、分岐栓本体10Aが具備する第一開口部15と、第一分岐接続部材30の一端部とが水密的に直接接合されることによって、分岐栓本体10Aに形成された横孔14Aと、第一分岐接続部材30に形成された第一分岐流路35と、が連通されることとなる。このため、分岐栓1Aは、分岐栓本体10Aの外周面(分岐栓本体10Aが具備する第一開口部15の上下)にシール部材を介装する必要がない。
したがって、分岐栓本体10Aと外装本体21Aとを嵌合する際にシール部材の破損を気にかける必要がなく作業に熟練を要することもないため作業が容易をとなり、分岐栓1Aの水密性を確実に確保することができる。
さらに、分岐栓本体10Aにシール部材を配置するためのスペースを確保する必要もなく、分岐栓本体10Aの長さを短く構成することができ、全体的に高さ寸法を抑えた分岐栓1Aを構成することが可能となる。
As described above, in the branch plug 1A, the branch plug main body 10A is provided in the exterior member 20A. In such a state, the first opening 15 included in the branch plug main body 10A and one end of the first branch connection member 30 are directly joined in a watertight manner to form the branch plug main body 10A. The lateral hole 14A and the first branch flow path 35 formed in the first branch connection member 30 are communicated with each other. For this reason, 1 A of branch plugs do not need to interpose a sealing member in the outer peripheral surface (upper and lower sides of the 1st opening part 15 which the branch plug main body 10A comprises) of 10 A of branch plug main bodies.
Therefore, it is not necessary to worry about the damage of the seal member when fitting the branch plug body 10A and the exterior body 21A, and the work does not require skill, so the work becomes easy, and the water tightness of the branch plug 1A is improved. It can be surely secured.
Furthermore, it is not necessary to secure a space for arranging the sealing member in the branch plug body 10A, the length of the branch plug body 10A can be shortened, and the branch plug 1A having a reduced height overall is provided. It can be configured.

また、分岐栓1Aにおいては、第一開口部15と第一分岐接続部材30の一端部とが直接接合されることにより、横孔14Aと第一分岐流路35とが連通される。このため、分岐栓1Aにおいては、第一開口部15(横孔14A)と連通する横溝を分岐栓本体10Aに形成することなく、第一分岐流路35に水を分岐させることができる。したがって、分岐栓本体10Aに横溝を形成する工程を省略することができ、ひいては、分岐栓の製造コストを低減させることができる。   Further, in the branch plug 1A, the first opening 15 and one end of the first branch connection member 30 are directly joined, whereby the lateral hole 14A and the first branch flow path 35 are communicated with each other. For this reason, in the branch plug 1A, water can be branched into the first branch flow path 35 without forming a lateral groove communicating with the first opening 15 (lateral hole 14A) in the branch plug body 10A. Therefore, the process of forming a lateral groove in the branch plug main body 10A can be omitted, and as a result, the manufacturing cost of the branch plug can be reduced.

ここで、従来の分岐栓においては、外装部材内に分岐栓本体を設けた状態で、フクロナットと混合水栓本体2とを螺合させた場合に、フクロナットと外装本体とが係合するような構成のものがあった。このような構成では、フクロナットを混合水栓本体2に螺合して外装部材を混合水栓本体2に固定した状態でも、外装部材内で分岐栓本体10Aが容易に移動し得るため、混合水栓本体2とカートリッジ3との間に分岐栓を配置する際に、その配置作業を煩雑なもとする可能性があった。
しかしながら、分岐栓1Aにおける分岐栓本体10Aの外周面には、半径方向外側に突出する周状(フランジ状)の突部17が形成されている。また、分岐栓1Aにおける外装部材20Aのフクロナット22には、分岐栓本体10Aに形成された突部17と係合するように、半径方向内側に突出する周状の突部23が設けられている。このため、フクロナット22と混合水栓本体2とにそれぞれに形成されたネジを螺合して、外装部材20Aを混合水栓本体2に固定すると、分岐栓本体10Aに形成された突部17と、フクロナット22に形成された突部23とが係合して、分岐栓本体10Aは混合水栓本体2に固定されることとなり動くことがない。したがって、混合水栓本体2とカートリッジ3との間に分岐栓1Aを配置する配置作業を簡便なものとすることができる。
Here, in the conventional branch plug, when the owl nut and the mixed water faucet body 2 are screwed together with the branch plug body provided in the exterior member, the owl nut and the exterior body are engaged. There was a configuration one. In such a configuration, since the branch plug body 10A can easily move within the exterior member even when the owl nut is screwed into the mixing faucet body 2 and the exterior member is fixed to the mixing faucet body 2, the mixed water When the branch plug is arranged between the plug body 2 and the cartridge 3, the arrangement work may be complicated.
However, on the outer peripheral surface of the branch plug main body 10A in the branch plug 1A, a circumferential (flange-shaped) protrusion 17 is formed that protrudes radially outward. In addition, the skirt nut 22 of the exterior member 20 </ b> A in the branch plug 1 </ b> A is provided with a circumferential protrusion 23 that protrudes inward in the radial direction so as to engage with the protrusion 17 formed on the branch plug body 10 </ b> A. . For this reason, when the exterior member 20A is fixed to the mixing faucet body 2 by screwing the screws formed on the crocodile nut 22 and the mixing faucet body 2, respectively, the protrusion 17 formed on the branch plug body 10A and The branch plug main body 10A is fixed to the mixed water faucet body 2 and does not move by engaging with the protrusion 23 formed on the owl nut 22. Accordingly, it is possible to simplify the arrangement work of arranging the branch plug 1A between the mixed water faucet body 2 and the cartridge 3.

分岐栓1Aにおいては、分岐栓本体10Aが具備する第一開口部15に第一分岐接続部材30の挿入部31を螺合挿入して、第一開口部15と挿入部31とを直接接合するものである。つまり、第一分岐接続部材30が分岐栓本体10Aに接合される周方向の位置は、分岐栓本体10Aが具備する第一開口部15の周方向の位置によって決定されている。このため、分岐栓1Aにおいては、混合水栓本体2とカートリッジ3との間に分岐栓1Aを装着する際に、分岐接続部材の周方向の位置を調整する作業を、特に要さないこととなる。したがって、混合水栓本体2とカートリッジ3との間に分岐栓1Aを配置する配置作業を良好なものとすることができる。   In the branch plug 1A, the insertion part 31 of the first branch connection member 30 is screwed into the first opening 15 of the branch plug body 10A, and the first opening 15 and the insertion part 31 are directly joined. Is. That is, the circumferential position where the first branch connection member 30 is joined to the branch plug body 10A is determined by the circumferential position of the first opening 15 provided in the branch plug body 10A. For this reason, in the branch plug 1A, when the branch plug 1A is mounted between the mixed water faucet body 2 and the cartridge 3, the operation of adjusting the circumferential position of the branch connection member is not particularly required. Become. Therefore, the arrangement | positioning operation | work which arrange | positions 1 A of branch plugs between the mixing faucet main body 2 and the cartridge 3 can be made favorable.

図5に示す如く、第一分岐接続部材30の他端側に形成された第一分岐流路35の開口部分は、盲栓などの蓋部材50を用いて閉塞することが可能である。具体的には、蓋部材50は、第一分岐接続部材30における六角部32の外郭線と略同一の内径を備える、椀形状の部材である。また、蓋部材50の外周面は六角ナット形状に形成され、また、蓋部材50の内周面は雌ネジが形成されている。
そして、蓋部材50の内部に、水漏れ防止用の環状のパッキン51を設け、第一分岐接続部材30の六角部32に形成された雄ネジと、蓋部材50に形成された雌ネジとを螺合させる。このようにして、第一分岐接続部材30に接続対象物を接続しないような場合には、前記第一分岐流路35の開口部分を閉塞して、湯または水の誤流出等を防止することができる。
As shown in FIG. 5, the opening portion of the first branch flow path 35 formed on the other end side of the first branch connection member 30 can be closed using a lid member 50 such as a blind plug. Specifically, the lid member 50 is a bowl-shaped member having an inner diameter substantially the same as the outline of the hexagonal portion 32 in the first branch connection member 30. Further, the outer peripheral surface of the lid member 50 is formed in a hexagonal nut shape, and the inner peripheral surface of the lid member 50 is formed with a female screw.

Screw together. In this way, when the connection object is not connected to the first branch connection member 30, the opening portion of the first branch flow path 35 is closed to prevent an erroneous outflow of hot water or water. Can do.

The first opening portion 15 and the second opening portion 16 are formed at the same height in the axial direction and at positions that are bilaterally symmetrical in the circumferential direction.

外装部材20Bは、略円筒形状の外装本体21Bを具備している。外装本体21Bにおける外周が大径に形成される下部には、内周面から外周面にむけて貫通される第一貫通孔25と第二貫通孔26が形成されている。第一貫通孔25と第二貫通孔26とは、それぞれ、上下方向において同一の高さに、且つ、周方向において左右対称となる位置に形成されている。   The exterior member 20B includes a substantially cylindrical exterior body 21B. A first through hole 25 and a second through hole 26 are formed in the lower part of the exterior main body 21B where the outer periphery is formed to have a large diameter. The first through-hole 25 and the second through-hole 26 are formed at the same height in the vertical direction and at positions that are bilaterally symmetrical in the circumferential direction.

第二分岐接続部材40は、六角ボルト形状の部材に、当該六角ボルト形状の軸心方向に貫通する第二分岐流路46が形成された部材である。具体的には、第二分岐接続部材40は、一端が、円柱形状に形成された挿入部41と、他端が、六角柱形状に形成された六角部42とから構成されている。そして、第二分岐接続部材40は、挿入部41と六角部42との互いの軸心を一致させるように、挿入部41の一方の底面に六角部42を一体的に設け、且つ、前記軸心方向に貫通する第二分岐流路46が形成されている。
また、第二分岐接続部材40における挿入部41の外径は、分岐栓本体10Bに形成された横孔14Bにおける外周面近傍の径(大きい径)と略同一の外径となるように形成されている。第二分岐接続部材40における挿入部41の外周面には、雄ネジが形成されている。第二分岐流路46の径は、分岐栓本体10Bに形成された横孔14Bにおける水側流路11側の径(小さい径)と略同一となるように形成されている。また、第二分岐接続部材40における六角部42の各角には、雄ネジが形成されている。
The second branch connection member 40 is a member in which a second branch channel 46 penetrating in the axial direction of the hexagon bolt shape is formed in a hexagon bolt shape member. Specifically, the second branch connection member 40 includes an insertion portion 41 having one end formed in a columnar shape, and a hexagonal portion 42 having the other end formed in a hexagonal column shape. And the 2nd branch connection member 40 is integrally provided with the hexagonal part 42 in one bottom face of the insertion part 41 so that the axial center of the insertion part 41 and the hexagonal part 42 may correspond, and the said axis | shaft A second branch channel 46 penetrating in the central direction is formed.
Further, the outer diameter of the insertion portion 41 in the second branch connection member 40 is formed to be substantially the same as the diameter (large diameter) in the vicinity of the outer peripheral surface of the lateral hole 14B formed in the branch plug main body 10B. ing. A male screw is formed on the outer peripheral surface of the insertion portion 41 in the second branch connection member 40. The diameter of the second branch channel 46 is formed to be substantially the same as the diameter (small diameter) on the water side channel 11 side in the lateral hole 14B formed in the branch plug body 10B. A male screw is formed at each corner of the hexagonal portion 42 in the second branch connection member 40.

以上のようにして構成された、分岐栓本体10B、外装部材20B、第一分岐接続部材30、および、第二分岐接続部材40を組み合わせることによって、分岐栓1Bが構成される。以下において、当該組み合わせの手順について具体的に説明する。
分岐栓本体10Bの上方からフクロナット22をかぶせて、分岐栓本体10Bとフクロナット22とを嵌合させる。
そして、斯る状態の分岐栓本体10Bの上方から外装本体21Aをかぶせて、分岐栓本体10Bと外装本体21Bとを嵌合させる。この場合、分岐栓本体10Bが具備する第一開口部15の位置と外装本体21Aに形成された第一貫通孔25の位置とを、および、分岐栓本体10Bが具備する第二開口部16の位置と外装本体21Aに形成された第二貫通孔26の位置とを、それぞれ一致させた状態で両者を嵌合させる。
さらに、第二分岐接続部材40の一端である挿入部41を第二貫通孔26に挿入し、且つ、当該第二分岐接続部材40の挿入部41と第二開口部16とを直接接合する。前記第二分岐接続部材40の挿入部41と第二開口部16との接合は、第二分岐接続部材40に形成された雄ネジと、分岐栓本体10Bにおける横孔14Bに形成された雌ネジとを螺合させることによって行う。この場合、第二分岐接続部材40の雄ネジと横孔14Bの雌ネジとの間は、接着剤等のシール材を介装するなどして水密的にシールされる。
なお、第1分岐接続分岐部材と第一開口部15との接合については、上記の説明と同様にして行うため、その説明を省略する。
また、分岐栓1Bを、混合水栓本体2とカートリッジ3との間に配置する際の手順は、分岐栓1Aの場合と同様であるため、その説明を省略する。
The branch plug 1B is configured by combining the branch plug main body 10B, the exterior member 20B, the first branch connection member 30, and the second branch connection member 40 configured as described above. Below, the procedure of the said combination is demonstrated concretely.
Cover the branch plug main body 10B with the owl nut 22 by placing the owl nut 22 over the branch plug main body 10B.
Then, the exterior main body 21A is covered from above the branch plug body 10B in such a state, and the branch body 10B and the exterior body 21B are fitted. In this case, the position of the first opening 15 provided in the branch plug main body 10B and the position of the first through hole 25 formed in the exterior main body 21A and the second opening 16 provided in the branch plug main body 10B. The two are fitted in a state in which the position and the position of the second through hole 26 formed in the exterior body 21A are matched.
Further, the insertion portion 41 that is one end of the second branch connection member 40 is inserted into the second through hole 26, and the insertion portion 41 and the second opening portion 16 of the second branch connection member 40 are directly joined. The insertion portion 41 of the second branch connection member 40 and the second opening 16 are joined by a male screw formed in the second branch connection member 40 and a female screw formed in the lateral hole 14B in the branch plug body 10B. By screwing together. In this case, a space between the male screw of the second branch connection member 40 and the female screw of the lateral hole 14B is sealed in a watertight manner by interposing a sealing material such as an adhesive.
In addition, since it joins similarly to said description about joining of a 1st branch connection branch member and the 1st opening part 15, the description is abbreviate | omitted.
Further, since the procedure for disposing the branch plug 1B between the mixed water faucet body 2 and the cartridge 3 is the same as that of the branch plug 1A, the description thereof is omitted.

以上のようにして、分岐栓1Bにおいては、分岐栓本体10Bが外装部材20B内に設けられる。そして、斯る状態において、分岐栓本体10Bが具備する第二開口部16と、第二分岐接続部材40の一端部とが水密的に直接接合されることによって、分岐栓本体10Bに形成された横孔14Bと、第二分岐接続部材30に形成された第二分岐流路36と、が連通されることとなる。このため、分岐栓1Bは、分岐栓本体10Bの外周面(分岐栓本体10Bが具備する第二開口部16の上下)にシール部材を介装する必要がない。
したがって、分岐栓本体10Bと外装本体21Bとを嵌合する際にシール部材の破損を気にかける必要がなく作業に熟練を要することもないため作業が容易をとなり、分岐栓1Bの水密性を確実に確保することができる。
さらに、分岐栓本体10Bにシール部材を配置するためのスペースを確保する必要もなく、分岐栓本体10Bの長さを短く構成することができ、全体的に高さ寸法を抑えた分岐栓1Bを構成することが可能となる。
As described above, in the branch plug 1B, the branch plug body 10B is provided in the exterior member 20B. In this state, the second opening 16 provided in the branch plug main body 10B and the one end of the second branch connection member 40 are directly joined in a watertight manner to form the branch plug main body 10B. The lateral hole 14B and the second branch flow path 36 formed in the second branch connection member 30 are communicated with each other. For this reason, the branch plug 1B does not need to interpose a seal member on the outer peripheral surface of the branch plug main body 10B (up and down of the second opening 16 provided in the branch plug main body 10B).
Therefore, when fitting the branch plug body 10B and the exterior body 21B, it is not necessary to worry about the damage of the seal member and the work does not require skill, so the work becomes easy and the water tightness of the branch plug 1B is improved. It can be surely secured.
Further, it is not necessary to secure a space for disposing the sealing member in the branch plug main body 10B, the length of the branch plug main body 10B can be shortened, and the branch plug 1B having a reduced height overall is provided. It can be configured.

ここで、昨今の台所設備事情においては、分岐水栓の接続対象物が2台(例えば、整水器と食洗機の2台)となる場合がある。もっとも、従来における分岐栓は、分岐接続部材を1つしか具備していなかったため、接続対象物が2台ある場合においても、同時に当該2台の接続対象物と接続することができず、台所作業を煩雑なものとしていた。
しかしながら、分岐栓1Bは、第一分岐接続部材30と第二分岐接続部材40とを具備している。このため、接続対象物が2台あるような場合においても、第一分岐接続部材30および第二分岐接続部材40と当該2台の接続対象物とを同時に接続することができ、台所作業を良好に行うことができる。
Here, in recent kitchen equipment circumstances, there are cases where there are two objects to be connected to the branch faucet (for example, two units, a water conditioner and a dishwasher). However, since the conventional branch plug has only one branch connection member, even when there are two connection objects, it cannot be connected to the two connection objects at the same time, and kitchen work Was complicated.
However, the branch plug 1 </ b> B includes the first branch connection member 30 and the second branch connection member 40. For this reason, even when there are two connection objects, the first branch connection member 30 and the second branch connection member 40 and the two connection objects can be connected at the same time, and the kitchen work is good. Can be done.

分岐栓1Bにおいては、第一開口部15と第二開口部16とは、それぞれ、周方向において左右対称となる位置に形成されている。第一貫通孔25と第二貫通孔26とは、それぞれ、周方向において左右対称となる位置に形成されている。このため、第一分岐接続部材30と第一開口部15を、および、第二分岐接続部材40と第二開口部16とをそれぞれ接合した際には、第一分岐接続部材30および第二分岐接続部材40とは、平面視で左右対称に、外装部材20Bからそれぞれ延出することとなる。したがって、左右のいずれの方向に接続対象物が配置されていている場合であっても、第一分岐接続部材30または第二分岐接続部材40と当該接続対象物とを容易に接続することができる。   In the branch plug 1 </ b> B, the first opening 15 and the second opening 16 are formed at positions that are left-right symmetrical in the circumferential direction. The first through hole 25 and the second through hole 26 are respectively formed at positions that are left-right symmetrical in the circumferential direction. Therefore, when the first branch connection member 30 and the first opening 15 and the second branch connection member 40 and the second opening 16 are joined, respectively, the first branch connection member 30 and the second branch The connecting member 40 extends from the exterior member 20 </ b> B symmetrically in plan view. Therefore, even if the connection object is arranged in any of the left and right directions, the first branch connection member 30 or the second branch connection member 40 and the connection object can be easily connected. .

第一開口部15と第二開口部16とは、それぞれ、上下方向において同一の高さに形成されている。第一貫通孔25と第二貫通孔26とは、それぞれ、軸心方向において同一の高さに形成されている。このため、第一分岐接続部材30と第一開口部15、および、第二分岐接続部材40と第二開口部16とをそれぞれ接合した際には、第一分岐接続部材30および第二分岐接続部材40とは、正面視で軸心方向において同一の高さで、外装部材20Bからそれぞれ延出することとなる。したがって、分岐栓1Bのように、分岐栓の軸心方向の長さを長く構成することなく、また、分岐接続部材を2つ具備する分岐栓を実現することができる。   The first opening 15 and the second opening 16 are each formed at the same height in the vertical direction. The first through hole 25 and the second through hole 26 are each formed at the same height in the axial direction. For this reason, when the 1st branch connection member 30 and the 1st opening part 15, and the 2nd branch connection member 40 and the 2nd opening part 16 were joined, respectively, the 1st branch connection member 30 and the 2nd branch connection The members 40 respectively extend from the exterior member 20B at the same height in the axial direction when viewed from the front. Therefore, unlike the branch plug 1B, a branch plug having two branch connection members can be realized without increasing the axial length of the branch plug.

また、分岐栓1Bにおいては、図8に示す如く、分岐栓1Aと同様に、蓋部材50を用いて、第二分岐接続部材40の他端側に形成された第二分岐流路46の開口部分を閉塞することが可能である。このように、接続対象物が、第一分岐接続部材30または第二分岐接続部材40のいずれか一方にしか接続されない場合には、蓋部材50を用いて、第一分岐接続部材30の他端側に形成された第一分岐流路35の開口部分、または、前記第二分岐流路46の開口部分を閉塞して、接続対象物と接続されない側の分岐接続部材から、湯または水が流出することを防止することができる。   Further, in the branch plug 1B, as shown in FIG. 8, similarly to the branch plug 1A, the opening of the second branch channel 46 formed on the other end side of the second branch connection member 40 using the lid member 50 is used. It is possible to close the part. Thus, when the connection object is connected to only one of the first branch connection member 30 and the second branch connection member 40, the other end of the first branch connection member 30 is used using the lid member 50. Hot water or water flows out from the branch connecting member on the side that is not connected to the connection object by closing the opening of the first branch channel 35 formed on the side or the opening of the second branch channel 46. Can be prevented.

ここで、分岐栓本体10Bの横孔14Bは、湯側流路12と水側流路11とのいずれにも連通するように、分岐栓本体10Bに形成される場合がある。例えば、混合水栓の径が小さいため、それに合わせて分岐栓の径を小さく構成する必要があって、湯側流路12および水側流路11の何れかと連通しないように横孔14Bを形成するだけのスペースがない場合や、3台以上の接続先との接続を想定して、分岐栓本体10Bに横孔14Bとは別の横孔14を形成するような場合である。
このように、分岐栓本体10Bの横孔14Bが、湯側流路12と水側流路11とのいずれにも連通するような場合には、そのままでは分岐接続部材から流出させる液体は湯と水の混合液となってしまい、湯または水を分岐させてその一方のみを接続対象物に流出させることはできない。
もっとも、以上のような場合においても、湯側流路12または水側流路11を閉塞する閉塞部材60を、湯側流路12または水側流路11に挿入することによって、湯側流路12または水側流路11のいずれか一方のみに横孔14Bが連通される構成にすることができる。このように構成することによって、分岐栓本体10Bに形成された横孔14Bが、湯側流路12および水側流路11に連通するような場合でも、湯または水のみを容易に分岐して第一分岐接続部材30および第二分岐接続部材40から流出させることができる。
Here, the lateral hole 14B of the branch plug main body 10B may be formed in the branch plug main body 10B so as to communicate with both the hot water side flow path 12 and the water side flow path 11. For example, since the diameter of the mixed water faucet is small, it is necessary to configure the diameter of the branching faucet accordingly, and the horizontal hole 14B is formed so as not to communicate with either the hot water side channel 12 or the water side channel 11. This is the case where there is not enough space to do so, or a case where a lateral hole 14 different from the lateral hole 14B is formed in the branch plug main body 10B, assuming connection with three or more connection destinations.
Thus, when the lateral hole 14B of the branch plug body 10B communicates with both the hot water side channel 12 and the water side channel 11, the liquid that flows out from the branch connection member as it is is hot water. It becomes a mixed solution of water, and it is impossible to branch hot water or water and flow only one of them into the connection object.
Of course, even in the above case, the hot water channel is inserted by inserting the closing member 60 that closes the hot water channel 12 or the water channel 11 into the hot water channel 12 or the water channel 11. The lateral hole 14 </ b> B can be communicated only with either the 12 or the water-side flow path 11. With this configuration, even when the lateral hole 14B formed in the branch plug main body 10B communicates with the hot water channel 12 and the water channel 11, only hot water or water can be easily branched. It can flow out from the first branch connection member 30 and the second branch connection member 40.

具体的には、図9から図11に示す如く、分岐栓本体10Bに形成される湯側流路12の上方部12aは、その径が、水側流路11の径と略同一の径となるように、且つ、上方部12aの上下中途部において横孔14Bの後方と連通するように形成されている。また、湯側流路12の下方部12bは、その径が、前記上方部12aの径より小さい径となるように形成されている。   Specifically, as shown in FIGS. 9 to 11, the upper portion 12 a of the hot water side channel 12 formed in the branch plug body 10 </ b> B has a diameter substantially the same as the diameter of the water side channel 11. In addition, the upper portion 12a is formed so as to communicate with the rear of the horizontal hole 14B in the middle of the upper and lower portions 12a. Further, the lower part 12b of the hot water side channel 12 is formed to have a diameter smaller than the diameter of the upper part 12a.

閉塞部材60は、湯側流路12の上方部12aに挿入可能なように、その外径が、湯側流路12の上方部12aの内径と略同一の、また、その内径が、湯側流路12の下方部12bの内径と略同一の筒形状に形成されている。閉塞部材60の軸心方向の長さは、湯側流路12の上方部12aの長さと略同一の長さとなるように形成されている。閉塞部材60の上下中途部、即ち、湯側流路12の上方部12aに閉塞部材60を挿入した際における横孔14Bと湯側流路12とが連通する部分に相当する部分には、周状に凹溝62が形成されている。
閉塞部材60には、凹溝62の上下部に、図示しない位置決め溝が各々形成されており、当該位置決め溝にOリング61・61が嵌装されている。
The outer diameter of the closing member 60 is substantially the same as the inner diameter of the upper portion 12a of the hot water side channel 12 so that the closing member 60 can be inserted into the upper portion 12a of the hot water side flow channel 12. It is formed in a cylindrical shape that is substantially the same as the inner diameter of the lower portion 12 b of the flow path 12. The length of the closing member 60 in the axial direction is formed so as to be substantially the same as the length of the upper portion 12a of the hot water channel 12. In the middle of the upper and lower portions of the closing member 60, that is, the portion corresponding to the portion where the horizontal hole 14B and the hot water side channel 12 communicate with each other when the closing member 60 is inserted into the upper portion 12a of the hot water side channel 12, A concave groove 62 is formed in a shape.
In the closing member 60, positioning grooves (not shown) are respectively formed in the upper and lower portions of the concave groove 62, and O-rings 61 and 61 are fitted in the positioning grooves.

以上のように構成された閉塞部材60が、湯側流路12の上方部12aに挿入されると、横孔14Bと湯側流路12との連通は遮断、つまり、湯側流路12は横孔14Bに対して閉塞されることとなる。そして、横孔14Bは、湯側流路12に連通されず、水側流路11にのみ連通されることとなる。したがって、閉塞部材60によって、分岐栓本体10Bに形成された横孔14Bが、湯側流路12および水側流路11に連通するような場合でも、水のみを分岐させることができる。   When the blocking member 60 configured as described above is inserted into the upper portion 12a of the hot water side flow path 12, the communication between the lateral hole 14B and the hot water side flow path 12 is blocked, that is, the hot water side flow path 12 is It will be obstruct | occluded with respect to the horizontal hole 14B. And the horizontal hole 14B is not connected to the hot water side flow path 12, but is connected only to the water side flow path 11. Therefore, even when the horizontal hole 14B formed in the branch plug main body 10B communicates with the hot water side channel 12 and the water side channel 11 by the closing member 60, only water can be branched.

なお、閉塞部材60によって、水側流路11を遮断する構成としてもよいものとする。また、水側流路11と湯側流路12との形状を、ともに閉塞部材60を挿入可能な形状に形成した場合には、湯側流路12と水側流路11とのいずれか一方を選択して遮断することが可能となる。   In addition, the water-side flow path 11 may be blocked by the closing member 60. Further, when the shapes of the water side channel 11 and the hot water side channel 12 are both formed such that the closing member 60 can be inserted, either the hot water side channel 12 or the water side channel 11 is used. It becomes possible to select and block.

また、凹溝62が形成されていない閉塞部材を、湯側流路12また水側流路11に挿入した場合には、分岐栓本体10Bの構成によっては、第一開口部15と第二開口部16との間は当該閉塞部材により遮断されることとなる場合がある。例えば、横孔14Bの径が湯側流路12の径より小さく、当該横孔14Bの軸心と当該湯側流路12の軸心とが交差しているような場合である。
しかしながら、閉塞部材60には凹溝62が形成されているため、閉塞部材60を湯側流路12また水側流路11に挿入しても、第一開口部15と第二開口部16との間を遮断することなく、第一開口部15と第二開口部16との間は、凹溝62を介して連通することとなる。このため、閉塞部材60を、湯側流路12また水側流路11に挿入しても、第一分岐接続部材30と第二分岐接続部材40とのいずれにも、水を分岐させることができる。
Further, when a blocking member in which the concave groove 62 is not formed is inserted into the hot water side channel 12 or the water side channel 11, the first opening 15 and the second opening may be formed depending on the structure of the branch plug main body 10B. The portion 16 may be blocked by the blocking member. For example, the diameter of the horizontal hole 14B is smaller than the diameter of the hot water side flow path 12, and the axial center of the horizontal hole 14B and the axial center of the hot water side flow path 12 intersect.
However, since the recessed member 62 is formed in the closing member 60, even if the closing member 60 is inserted into the hot water channel 12 or the water channel 11, the first opening 15 and the second opening 16 The first opening 15 and the second opening 16 communicate with each other through the concave groove 62 without blocking the gap. For this reason, even if the blocking member 60 is inserted into the hot water channel 12 or the water channel 11, the water can be branched into either the first branch connection member 30 or the second branch connection member 40. it can.

第一開口部15と第二開口部16とが、また、第一貫通孔25と第二貫通孔26とが、それぞれ上下方向において同一の高さに形成されることに特に限定するものではない。また、第一開口部15と第二開口部16とが、また、第一貫通孔25と第二貫通孔26とが、周方向において左右対称となる位置に形成されることに特に限定するものではない。   The first opening 15 and the second opening 16, and the first through hole 25 and the second through hole 26 are not particularly limited to being formed at the same height in the vertical direction. . Further, the first opening 15 and the second opening 16 are particularly limited to be formed at positions where the first through hole 25 and the second through hole 26 are symmetrical in the circumferential direction. is not.

外装部材20A・20Bは、金属素材からなるが、樹脂素材からなる構成としてもよいものとする。外装部材20A・20Bは、外装本体21Aとフクロナット22とを一体的に構成する場合でも良いものとする。分岐栓本体10A・10Bを、混合水栓本体2に固定する方法として、フクロナット22によって係合させて固定する方法に特に限定するものではない。   The exterior members 20A and 20B are made of a metal material, but may be made of a resin material. The exterior members 20A and 20B may be configured such that the exterior body 21A and the owl nut 22 are integrally formed. The method of fixing the branch plug main bodies 10A and 10B to the mixed water faucet main body 2 is not particularly limited to the method of engaging and fixing with the frog nut 22.

第一・第二分岐接続部材30・40と第一・第二開口部15・16との接合は、第一・第二分岐接続部材30・40の挿入部31・41と横孔14A・14Bとの間に接着剤等のシール材を介在させた状態で、第一・第二分岐接続部材30・40に形成された雄ネジと、分岐栓本体10A・10Bにおける横孔14A・14Bに形成された雌ネジとを螺合させることに特に限定するものではない。つまり、例えば第一・第二分岐接続部材30・40と第一・第二開口部15・16との接合は、第一・第二分岐接続部材30・40の挿入部31・41と横孔14A・14Bとの間に接着剤等のシール材を介在させた状態で、当該挿入部31・41を第一・第二開口部15・16から横孔14A・14Bに圧入するなど挿入して、挿入部31・41と横孔14A・14Bを接合させてもよいものとする。また、上述したようにネジの螺合によってのみ、第一・第二分岐接続部材30・40と第一・第二開口部15・16とを接合してもよいものとする。   The first and second branch connection members 30 and 40 and the first and second openings 15 and 16 are joined by the insertion portions 31 and 41 of the first and second branch connection members 30 and 40 and the lateral holes 14A and 14B. With a sealing material such as an adhesive interposed between the male screw formed on the first and second branch connection members 30 and 40 and the lateral holes 14A and 14B in the branch plug main bodies 10A and 10B. It does not specifically limit to screwing with the formed female screw. That is, for example, the first and second branch connection members 30 and 40 and the first and second openings 15 and 16 are joined by the insertion portions 31 and 41 of the first and second branch connection members 30 and 40 and the horizontal holes. 14A and 14B with a sealing material such as an adhesive interposed between the first and second openings 15 and 16 and inserting the insertion parts 31 and 41 into the horizontal holes 14A and 14B.
