DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Below, 1st Embodiment of this invention is described based on FIGS. 1-3.
[0011]
As shown in FIG. 1, the sink 11 is provided with a work top 12 and a sink 13 adjacent to each other on the left and right. A ridge 12a that functions as a peripheral wall is formed on the periphery of the upper surface of the work top 12 except for the sink 13 side. Further, the upper surface of the work top 12 is gently lowered toward the sink 13 so that water on the upper surface of the work top 12 flows into the sink 13. Then, on the upper surface of the worktop 12, work such as preparation for cooking is performed. A water faucet (not shown) is provided at an upper position of the sink 13, and food and tableware are washed by discharging water from the water faucet.
[0012]
As shown in FIGS. 1 to 3, a mounting pipe 14 is erected and fixed by a nut 16 via a packing 15 on the rear end of the worktop 12 on the side opposite to the sink 13, and a mounting portion 14 a on the upper portion thereof. Projectingly formed. A support pipe 17 is rotatably attached to the attachment portion 14a of the attachment pipe 14, and a support portion 17a is formed so as to protrude from the outer peripheral surface thereof.
[0013]
A water discharge pipe 18 is attached to the support portion 17a of the support pipe 17 so as to be rotatable about its own horizontal axis extending in the left-right direction in FIG. An operation knob 19a is projected from the upper surface of the. On the peripheral surface of the water discharge pipe 18, a plurality of water discharge holes 20 for discharging cleaning water toward the upper surface of the worktop 12 are formed at predetermined intervals in the longitudinal direction.
[0014]
Then, by holding the water discharge pipe 18 and rotating the support pipe 17 around the attachment portion 14a of the attachment pipe 14, the water discharge pipe 18 is horizontally rotated, and the use position P1 indicated by a solid line in FIG. To the non-use position P2 indicated by a chain line in FIG. And in the use position P1, the water discharge pipe 18 is extended ahead along the illustration left end edge of the worktop 12, and in the non-use position P2, the water discharge pipe 18 is right along the rear end edge of the worktop 12. It is designed to be extended to the direction.
[0015]
Further, with the water discharge pipe 18 disposed at the use position P1, as shown in FIG. 3, the water discharge pipe 18 is rotated around the horizontal axis about the support portion 17a of the support pipe 17 by the operation knob 19a. As a result, the opening direction (vertical direction) of the plurality of water discharge holes 20 is changed. Thereby, the direction of the wash water discharged from the water discharge hole 20 is changed, and the flight distance of the wash water is adjusted.
[0016]
As shown in FIGS. 1 and 2, a supply pipe 21 is connected to the lower end of the mounting pipe 14, and water from a water supply pipe 23 and a hot water supply pipe 24 are connected to the supply pipe 21 via a mixing faucet 22. Hot water or a mixed water thereof is supplied. The mixing faucet 22 is disposed at the rear portion of the work top 12, and an operation handle 22a is provided on the front surface thereof. Then, the temperature of the mixed water is adjusted by rotating the operation handle 22a in the left-right direction, and the opening / closing of the mixed water and the flow rate are adjusted by rotating the operation handle 22a in the up-down direction. To be done.
[0017]
Next, functions of the water tap and the sink configured as described above will be described.
Now, in the sink 11, when work such as cooking preparation is performed on the upper surface of the work top 12, as shown by a chain line in FIG. 12 extends along the rear edge. Thereby, the preparation of cooking etc. can be performed normally using the whole upper surface of the worktop 12, without the water discharge pipe 18 getting in the way.
[0018]
In this way, when the upper surface of the work top 12 is cleaned after preparation for cooking, etc., as shown by the solid line in FIG. 1, the water discharge pipe 18 is rotated to the use position P1, and the work top 12 Extend along the left edge. In this state, when the mixing faucet 22 is opened by the operation handle 22a, the washing water is discharged from the water discharge hole 20 of the water discharge pipe 18, flows to the right along the upper surface of the work top 12, and flows down into the sink 13. Thereby, the upper surface of the worktop 12 can be easily washed with water, hot water or lukewarm water.
[0019]
In this case, as shown in FIG. 3, when the water discharge pipe 18 is rotated around the axis by the operation knob 19a, the opening direction of the water discharge holes 20 is changed. Thereby, the flight distance of the cleaning water discharged from the water discharge hole 20 is changed, and the cleaning water can be discharged to a desired position on the work top 12.
[0020]
Therefore, according to this embodiment, the following effects can be obtained.
(A) In the water faucet and sink for the sink, a water discharge pipe 18 is disposed along the upper surface of the work top 12, and the water discharge pipe 18 discharges cleaning water toward the upper surface of the work top 12.

For this reason, the upper surface of the worktop 12 can be easily cleaned without trouble by the washing water discharged from the water discharge hole 20 of the water discharge pipe 18, and the upper surface of the worktop 12 can be maintained in a clean state.
[0021]
(B) In the sink faucet and sink, the water discharge pipe 18 is disposed on the edge of the worktop 12 on the side opposite to the sink 13. Then, the cleaning water discharged from the water discharge hole 20 to the upper surface of the work top 12 flows into the sink 13 due to the ridges 12a functioning as the peripheral wall of the work top 12 and the gentle inclination of the upper surface of the work top 12. Yes. Therefore, it is possible to prevent the cleaning water discharged from the water discharge hole 20 from collecting on the upper surface of the work top 12 or dripping from the front edge of the upper surface of the work top 12.
[0022]
(C) In this water faucet and sink for a sink, the water discharge pipe 18 is configured to be able to change between a use position P1 and a non-use position P2. For this reason, when performing work such as preparation for cooking on the work top 12, the water discharge pipe 18 can be shifted to the non-use position P2. Therefore, preparation of cooking and the like can be performed normally using the entire upper surface of the work top 12 without the water discharge pipe 18 getting in the way.
[0023]
(D) In this sink faucet and sink, the flight distance of the cleaning water discharged from the plurality of water discharge holes 20 is changed by rotating the water discharge pipe 18 around the axis. Yes. For this reason, the supply position of the cleaning water discharged from the water discharge hole 20 can be arbitrarily changed according to the degree of dirt on the upper surface of the work top 12, etc., and the upper surface of the work top 12 can be more easily cleaned. .
[0024]
