  As shown in FIGS. 8 to 9, in the valve operating body 46, a fixed plate 63 sandwiched by a pair of packing plates 64 is disposed between the first and second valve case plates 61 and 62. The fixing plate 63 is sandwiched and fixed by a plurality of bolts 65 between the first and second valve case plates 61 and 62. A pair of through holes 63a and 64a and one insertion hole 63b and 64b are formed in the fixing plate 63 and both packing plates 64 so as to correspond to each other. A recess 61a and an insertion hole 61b are formed in the first valve case plate 61 so as to correspond to the through holes 63a and 64a and the insertion holes 63b and 64b. On one side of the fixed plate 63 (hereinafter, the fixed plate 63 will be described as including both packing plates 64), a movable plate 66 is disposed so as to be movable in a direction in which the movable plate 66 contacts and separates from the fixed plate 63. First and second valve bodies 67 and 68 project from the side surface of the movable plate 66 and are slidably fitted into the through holes 63a and 64a and the recess 61a. The first valve body 67 is formed in a cylindrical shape, and a communication hole 67a is provided at the center thereof. On the other hand, the 2nd valve body 68 is formed in the column shape.

  On the side surface of the movable plate 66, a short columnar working body 69 projects and is inserted into the insertion holes 63b, 64b, 61b of the fixed plate 63 and the first valve case plate 61 so as to be able to appear and retract. A spring receiving recess 70 is formed on the inner surface of the second valve case plate 62. A spring 71 for biasing the movable plate 66 toward the fixed plate 63 is interposed between the spring receiving recess 70 and the movable plate 66. As shown in FIGS. 8 and 10, the movable plate 66 is normally disposed at a position where it is joined to the fixed plate 63 by the biasing force of the spring 71, and the actuating body 69 is inserted through the insertion holes 63b and 64b and the recess 61a. One valve case plate 61 protrudes outward.

  Connection holes 72 to 74 are formed in the lower portions of the peripheral surfaces of the recesses 61 a of the first valve case plate 61 and the spring receiving recesses 70 of the second valve case plate 62. The end of the first pilot tube 47a on the valve operating body 46 side is connected to the connection hole 72 of the recess 61a corresponding to the first valve body 67. The end of the second pilot tube 47 b is connected to the connection hole 73 of the spring receiving recess 70. Furthermore, the end of the third pilot tube 47 c is connected to the connection hole 74 of the recess 61 a corresponding to the second valve body 68.

Is opened, and the connection hole 72 is communicated with the connection hole 73 via the communication hole 67a. For this reason, as indicated by arrows in FIGS. 7 and 10, the water pressure on the primary side of the flow passage 56 in the water stop valve 39 passes through the first pilot tube 47a, the connection holes 72 and 73, and the second pilot tube 47b. , Acting on the back side of the valve body 58 of the water stop valve 39. As a result, the valve body 58 is pressed against the valve seat 57 and the flow passage 56 of the water stop valve 39 is closed. Therefore, water does not flow into the water purifier 38 from the water supply pipe 30 via the purified water supply pipe 37a or flow out of the purified water supply pipe 37b.

  On the other hand, as shown in FIGS. 12 and 13, when the operating body 69 of the valve operating body 46 is pressed through the operating rod 49 by the turning operation of the operating handle 50, the movable plate 66 is fixed. The communication hole 67 a of the first valve body 67 is closed by joining with the second valve case plate 62. Further, the space between the movable plate 66 and the fixed plate 63 is opened, and a passage is formed there. As a result, the connection hole 72 is blocked from communicating with the connection hole 73, and the connection hole 72 serves as a gap between the outer circumferences of the valve bodies 67 and 68 and the through holes 63 a and 64 a, and the fixed plate 63 and the movable plate 66. To the connection hole 74 through the passage. For this reason, as shown by arrows in FIGS. 13 and 14, the water pressure on the primary side of the flow passage 56 in the water stop valve 39 passes through the first pilot tube 47a, the connection holes 72 and 74, and the third pilot tube 47c. Then, it comes out to the secondary side of the flow passage 56 of the water stop valve 39. Accordingly, the application of the primary pressure to the back side of the valve body 58 is released, the valve body 58 is moved to a position away from the valve seat 57 by the pressure in the flow path 56, and the flow path 56 of the water stop valve 39 is opened. . For this reason, water flows into the water purifier 38 from the water supply pipe 30 through the purified water supply pipe 37a, and the water purifier 38 enters a state where the water purification treatment is performed.

  Therefore, if the operating body 69 is moved to the position shown in FIGS. 12 and 13 by operating the operation handle 50, tap water from the water supply main plug 29 side flows into the water purifier 38 via the purified water supply pipe 37a and the like. Then, it is purified and discharged from the discharge unit 26 through the purified water supply pipe 37b and the like, and can be used for drinking and the like.

  As shown in FIGS. 4 to 6, a connecting portion 77 protrudes on the side surface of the faucet 23 opposite to the mounting portion 42 of the adapter 41, and a male screw 77 a is formed on the outer periphery of the connecting portion 77. ing.

Moreover, the hot water mixing valve part 27 of the faucet 23 is directly connected to the water supply pipe 30 without connecting the purified water supply pipes 37 a and 37 b via the branch cheese 36. Further, a branch cheese 82 is connected to the hot water supply pipe 32, and a branch pipe 83 is connected between the branch cheese 82 and the connection passage 78 of the adapter 41.

  A branch stop cock 84 having an operation handle 85 is detachably connected to the connection portion 77 of the adapter 41. A dishwasher 86 as an external device is detachably connected to the secondary side of the branch stop cock 84 via a coupling 87. When the branch stop cock 84 is opened by operating the operation handle 85, the hot water from the hot water supply pipe 32 passes through the branch pipe 83, the connection passage 78 of the adapter 41, and the branch stop cock 84, and then the dishwasher 86. Supplied in. For this reason, dishwashing can be performed in the dishwasher 86.

  In the faucet 23, an adapter 41 is fitted on the outer periphery of the base of the faucet body 24, and an attachment portion 42 is provided on the adapter 41. And the operation mechanism 43 for operating the water stop valve 39 connected in the purified water supply pipes 37a and 37b is attached to this attachment part 42 so that attachment or detachment is possible. Therefore, if the faucet 23 is attached to the sink 21 in advance and constitutes a part of the kitchen system, even if the water purifier 38 is additionally attached after that, a water faucet dedicated to the water purifier is provided separately. There is no need to replace the existing faucet 23 with an expensive faucet having an operation function of the water stop valve 39 for the water purifier 38.

  That is, by incorporating the operation mechanism 43 including the valve operating body 46 and the operation handle 50 into the mounting portion 42 of the adapter 41, the operation function of the water stop valve 39 related to the water purifier 38 can be easily performed with respect to the existing faucet 23. Can be retrofitted. Therefore, the additional equipment of the water purifier 38 can be performed at low cost. In addition, unlike the case where a separate water purifier dedicated faucet is provided, the operation portion of the water stop valve 39 is not disposed at a position away from the faucet, and is provided integrally on the faucet body 24. Therefore, it is possible to prevent the possibility of deteriorating the aesthetics or deteriorating the operability.

  Further, in the faucet 23, the water stop valve 39 is opened and closed by switching the pilot flow path acting on the water stop valve 39 by the operation mechanism 43. For this reason, compared with the conventional method which uses a solenoid valve as a water stop valve, the cost of the water stop valve 39 and its operation configuration can be reduced, and electrical wiring and the like are no longer necessary. Easy to equip.

  In addition, in the faucet 23, a connection passage 78 is formed in the adapter 41 on the faucet body 24 for connecting a branch pipe 83 branched from a pipe such as the hot water supply pipe 32 and an external device. For this reason, when installing external devices, such as the dishwasher 86, an external device can be easily connected with piping using the existing faucet 23. FIG.

In addition, when the water purifier 38 and the dishwasher 86 are not used, the aesthetic appearance can be maintained by fitting the cap 81 or the cap 79 to the attachment portion 42 or the connection portion 77.
