Description

  The present invention relates to, for example, a hot and cold water mixing faucet that includes a horizontally long discharge port and performs a wide band-like (film-like) discharge from the discharge port.

  As a conventional faucet that performs wide discharge, there is one that prevents uneven discharge by providing a weir upstream of the discharge port (see, for example, Patent Documents 1 and 2).

Japanese Utility Model Publication No. 62-35717 Japanese Utility Model Publication No. 3-12968

  However, in the above-described water faucet, it is necessary to make the weir higher in order to more reliably prevent uneven discharge. However, the higher the weir, the larger the discharge pipe and thus the entire faucet. There's a problem.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hot and cold water mixing faucet that can perform a wide and strip-like discharge in a compact configuration.

  In order to achieve the above object, the hot and cold water mixing faucet according to the present invention includes a hot water supply pipe and a hot water from the water supply pipe after passing through the hot water mixing section and the flow rate adjustment section of the faucet body. It passes through the flat water channel which passes through back and above in this order, and it is constituted so that it may be discharged from a horizontally long discharge port in front of the faucet body (Claim 1).

  In the hot and cold water mixing faucet, two eccentric pipes are assembled to the faucet body arranged on the front side of the wall, and the two eccentric pipes are connected to the hot water supply pipe and the water supply pipe piped on the back side of the wall. Connected to the front side of the wall, and the faucet body has a wall-facing opening opening toward the wall and a reverse opening opening facing the back to the wall, the reverse opening Two through holes are provided to hold the eccentric pipe inserted from a portion to a position connectable to the hot water supply pipe or the water supply pipe so as not to come out of the opening facing the wall, and the hot water supply is inserted into the through hole. The eccentric pipe that is not connected to the pipe and the water supply pipe may be rotatable around the central axis of the eccentric pipe (claim 2).

  According to the first and second aspects of the present invention, a hot and cold water mixing faucet that can perform a wide and strip-like discharge with a compact configuration can be obtained.

  That is, in the conventional faucet that performs wide discharge, a member for forming a weir is separately provided on the upstream side of the discharge port in order to surely perform this wide discharge. However, there was a problem of increasing complexity and size.

  However, in the invention according to claim 1, the discharge member forms a water channel that reaches the front of the faucet body through the rear side and the upper side of the faucet body in this order on the upstream side of the discharge port. Since the flow path from the top to the top also plays the role of a weir, there is no need to provide a separate member for forming the weir as in the prior art.Therefore, the structure around the discharge port is simple and downsized accordingly. Thinning can be achieved. In addition, in the invention according to claim 1, since the faucet body is arranged using the vacant space below the discharge member, the faucet as a whole can be made compact and space-saving. it can.

  In the invention according to claim 2, a hot and cold water mixing faucet suitable for saving space of a so-called wall-mounted hot and cold water mixing faucet can be obtained.

  That is, in the conventional hot and cold water mixing faucet, since the eccentric tube is assembled on the back side (wall side) of the faucet body, the projecting width from the wall surface has increased accordingly, but in the invention according to claim 2, Since the eccentric tube is assembled to the faucet body in a state where the faucet body is inserted, the protrusion of the faucet body wall to the front side can be minimized, and the space can be greatly saved.

  The hot and cold water mixing faucet according to the first embodiment (hereinafter abbreviated as the first faucet) is a faucet of a type installed on a so-called deck surface or counter surface, as shown in FIG. It is installed on the upper surface (deck surface) of the rim portion R of the bathtub B, and is configured to supply hot water into the bathtub B. And the 1st faucet is equipped with the faucet body 1 and the discharge member 2 with which this faucet body 1 is mounted | worn, as shown to FIG. 2 (A) and (B) and FIG.

  As shown in FIG. 4 (A), the faucet body 1 passes through the check valve 3 and the flow rate adjustment unit 4 in this order to the hot water mixing unit 5 while the water from the hot water supply piping P1 However, after passing through the check valve 6 and the flow rate adjusting unit 7 to reach the hot water / mixing unit 5, the hot water reaching the hot / cold mixing unit 5 through different flow paths 13 and 14 (described later) is then supplied to the faucet body 1. It is comprised so that it may be derived | led-out to the back side. And the hot water led out to the back side of the faucet main body 1 passes through the flat water channel in the discharge member 2 which passes the back and upper direction of the faucet main body 1 in this order, and is a horizontally long discharge outlet in front of the faucet main body 1. It discharges toward the inside of bathtub B from 8 (refer FIG. 1, FIG. 4).

  The above is the outline of the configuration of the first faucet, and a more specific description will be given below.

  As shown in FIGS. 5A and 5B, the faucet body 1 has a hollow body member 10 having a hollow and symmetrical structure. The body member 10 is made of a casting (made of a copper alloy in this example), and as shown in FIGS. 5A and 5C, connection ports 11 and 12 are formed on the left and right sides of the bottom surface. A pipe P1 (see FIG. 4A) and a water supply pipe P2 (see FIG. 4A) are connected to the connection port 12, respectively.

  5 (A) and 5 (B), the body member 10 is partitioned, and the hot water flow path 13 extending from the connection port 11 to the hot water mixing section 5 at the upper center of the body member 10, and the connection port A water flow path 14 extending from 12 to the hot water / mixing section 5 is formed. 4A and FIG. 5A, the body member 10 has the check valve 3 and the flow rate adjusting unit 4 in the hot water channel 13 and the water channel 14 in the reverse direction. The stop valve 6 and the flow rate adjusting unit 7 are configured to be located respectively.

  In this example, as shown in FIG. 4 (A), the check valves 3 and 6 are inserted and fixed from the left and right sides of the lower part of the body member 10, respectively, and the flow rate adjusting parts 5 and 7 are inserted from the left and right sides of the upper part of the body member 10. Each valve unit is inserted and fixed. Here, the check valves 3 and 6 of this example are check valves with a flow rate adjustment (adjustment for limiting the maximum flow rate) function. In addition, each valve unit constituting the flow rate adjusting units 5 and 7 of the present example is operated by rotating the hot water flow rate adjusting handle 15 and the water flow rate adjusting handle 16 (see FIG. 4A), thereby causing the hot water channel 13 and the water flow channel. 14 is configured so that the flow rate of hot water and water flowing into the hot water mixing unit 5 through 14 can be individually adjusted.

  Note that the check valves 3 and 6 and the flow rate adjusters 5 and 7 may have a known configuration, and a detailed description thereof will be omitted here.

  On the other hand, as shown in FIGS. 5 (A) and 5 (B), the center part of the back surface of the body member 10 is recessed forward from the back surface of the body member 10, and the front part opens toward the hot water / mixing part 5. A rear opening 17 is provided, and a connecting pipe 18 made of metal (made of a copper alloy in this example) shown in FIGS. 6A and 6B is connected to the rear opening 17 (FIG. 4B )reference). As shown in FIG. 6 (A), the leading end side of the connecting pipe 18 has a smaller outer diameter than the rear end side, and a male screw 18a is formed on the outer peripheral surface of the leading end side. It can be screwed onto a female screw 17a (see FIG. 5B) formed in the rear opening 17. That is, the connecting pipe 18 is connected to the rear opening 17 by screwing the male screw 18 a of the connecting pipe 18 to the female screw 17 a of the rear opening 17. In addition, three sealing members (synthetic rubber O-rings in this example) 18b are attached to the connecting pipe 18, and the sealing member 18b at the distal end side of the connecting pipe 18 is in the connected state of the back opening 17 and the connecting pipe 18. Contributes to ensuring sealing performance.

  Furthermore, as shown in FIGS. 6A and 6B, the inner peripheral wall portion 18c on the rear end side of the connecting pipe 18 has a non-circular shape in cross-sectional view (in this example, a regular hexagonal shape). As a result, an appropriate tool (in this example, a hexagon wrench) that engages with the inner peripheral wall portion 18c is inserted into the inner peripheral wall portion 18c, and the connecting tube 18 can be easily connected to the rear opening 17 by rotating the tool. can do.

  Moreover, as shown in FIG.3 and FIG5 (A)-(C), the center lower part of the trunk | drum member 10 is open | released below. That is, a recessed space portion 19 that is recessed upward from the lower surface of the trunk member 10 is provided at the center lower portion of the trunk member 10. Further, as shown in FIG. 5A, the body member 10 has two obliquely extending screw holes 20 having an upper end communicating with the inner space of the rear opening 17 and a lower end communicating with the recessed space portion 19. It is formed symmetrically.

  As shown in FIG. 5A, a female screw 20a is provided on the inner wall surface of each screw hole 20, and a fixing screw 21 having a male screw 21a (see FIG. 7A) to be screwed to the female screw 20a is respectively provided. Screwed into the screw hole 20 (see FIG. 4A).

  As shown in FIGS. 7 (A) and 7 (B), a tip portion of the fixing screw 21 is provided with a recess portion 21b and a tapered surface 21c from the periphery of the recess portion 21b toward the rear end side. Further, the fixing screw 21 is provided with a recessed portion 21d having an inner peripheral wall portion having a non-circular sectional shape (regular hexagonal shape in this example) extending from the rear end surface toward the front end side. As a result, an appropriate tool (in this example, a hexagon wrench) that engages the inner peripheral wall portion of the recessed portion 21d is inserted from below the recessed space portion 19, and the tool is turned to rotate the fixing screw. 21 can be easily screwed into the screw hole 20.

  Further, as shown in FIGS. 5 (A) and 5 (B), the center lower part of the back surface of the body member 10 is recessed forward from the back surface of the body member 10 and is recessed through the front communication port 22a. A back surface communication hole 22 communicating with the space 19 is provided. As shown in FIG. 5B, the back surface communication hole 22 has a recessed amount in the front of the body member 10 smaller than that of the back surface opening 17. By the way, when the fixing screw 21 is screwed into the two screw holes 20 described above, it is necessary to insert a tool from the lower side of the recessed space portion 19 toward the two screw holes 20, but it extends obliquely. Since a tool may be inserted into the two screw holes 20 from obliquely below the recessed space 19, the peripheral wall of the back surface communication hole 22 does not hinder the insertion of the tool.

  On the other hand, the discharge member 2 is a member made of metal (in this example, made of stainless steel), and as shown in FIGS. 8A and 8D, a discharge pipe 23 having a bent plate-like appearance is provided. The discharge pipe 23 includes a base portion 24 extending in a substantially vertical direction and a mountain-shaped portion 25 extending in a mountain shape from above the base portion 24 toward the front of the base portion 24. The discharge port 8 is provided. In this example, the thickness t (see FIG. 8C) of the metal plate constituting the discharge member 2 is 2 mm, and the vertical width d of the flat water channel in the discharge member 2 (see FIG. 8C) is 3 mm.

  Further, as shown in FIGS. 8A, 8C, 8D, and 8F, a substantially cylindrical tube portion 26 made of metal (in this example, made of stainless steel) is provided on the front upper portion of the base portion 24. ing. In addition, this cylinder part 26 is joined to the base 24 by welding, for example. And the opening is formed in the location where the cylinder part 26 is joined in the front surface of the base 24 so that the inside of the cylinder part 26 and the inside of the base 24 (water discharge pipe 23) may communicate.

  Here, as shown in FIG. 8A, an annular tapered groove 27 is provided on the outer peripheral surface of the cylindrical portion 26 along the circumferential direction of the outer peripheral surface.

  Further, as shown in FIGS. 5A, 5C, 5D, and 5F, a substantially cylindrical female screw member 28 made of metal (in this example, made of stainless steel) is provided at the lower front surface of the base 24. ing. The female screw member 28 is joined to the base 24 by welding, for example.

  Then, as shown in FIGS. 4A and 4B, an insertion screw 29 that is inserted through the back surface communication hole 22 of the body member 10 is screwed to the female screw member 28. The insertion screw 29 has a head portion 29 a having a diameter larger than that of the communication port 22 a of the back surface communication hole 22, and the head portion 29 a has a non-circular sectional view similar to the recessed portion 21 d of the fixing screw 21. A recessed portion 29b having an inner peripheral wall portion having a shape (regular hexagonal shape in this example) is provided.

  Next, a method for attaching the discharge member 2 to the faucet body 1 will be described.

  (1) Assume that the faucet body 1 and the discharge member 2 are assembled in advance as shown in FIG. Accordingly, the hot water supply pipe P1 and the water supply pipe P2 are already connected to the body member 10 of the faucet body 1. The fixing screw 21 is not screwed into the screw hole 20 of the faucet body 1.

  (2) First, the cylindrical portion 26 and the female screw member 28 of the discharge member 2 are respectively inserted into the rear opening 17 and the rear communication hole 22 of the faucet body 1 (see FIG. 3).

  Thereby, the approximate positioning of the discharge member 2 is made. At this time, the cylindrical part 26 is fitted on the connecting pipe 18 extending toward the rear side of the faucet body 1 inside the rear opening 17 (see FIG. 5B) (FIG. 4 ( B)). And the sealing performance between the connecting pipe 18 and the cylinder part 26 connected by this external fitting is improved by the two sealing members 18b provided on the rear end side of the connecting pipe 18.

  (3) Subsequently, the two fixing screws 21 are respectively screwed into the two screw holes 20 from below, and the tip portions (tapered surfaces 21c) of the fixing screws 21 are tapered grooves 27 in the cylindrical portion 26. (See FIGS. 2 and 3B).

  That is, as the two fixing screws 21 are screwed, even after the tip portions (tapered surfaces 21c) of the fixing screws 21 abut against the groove walls of the tapered grooves 27, they slide on the groove walls. As a result, the tube portion 26 is drawn forward, and eventually the gap between the back surface of the faucet body 1 and the front surface of the base portion 24 of the discharge member 2 disappears, and the discharge member 2 is completely positioned. The member 2 is firmly fixed to the faucet body 1.

  (4) Further, the insertion screw 29 is screwed to the female screw member 28 (see FIG. 4B).

  At this time, the insertion screw 29 is inserted through the insertion port 22a of the back surface communication hole 22, and the head 29a is in contact with the peripheral wall of the insertion port 22a. Therefore, the fixing of the female screw member 28 and thus the discharge member 2 to the faucet body 1 is further strengthened by the screwing.

  In addition, you may perform this process (4) before the said process (3).

  With the above, the attachment of the discharge member 2 to the faucet body 1 is completed. In the first faucet assembled in this way, hot water and water from the hot water supply pipe P1 and the water supply pipe P2 are mixed with hot water as described above. After reaching the inside of the section 5, it is led out into the discharge member 2 through the connecting pipe 18 communicating with the hot water / mixing section 5.

  In the first faucet having the above-described configuration, wide and strip-like (film-like) discharge from the discharge port 8 can be performed satisfactorily. That is, in the conventional faucet that performs wide discharge, a member for forming a weir is separately provided on the upstream side of the discharge port in order to surely perform this wide discharge. However, there was a problem of increasing complexity and size.

  However, in the first faucet, the discharge member 2 forms a water channel on the upstream side of the discharge port 8 from the inside of the tubular portion 26 to the front of the faucet body 1 through the rear and upper sides of the faucet body 1 in this order. In addition, since the flow path from the base 24 of the discharge member 2 to the uppermost portion 25a of the chevron 25 also serves as a weir, there is no need to separately provide a member for forming a weir as in the prior art, Accordingly, the structure around the discharge port 8 can be made simple, downsized, and thinned accordingly. Moreover, in the first faucet, the faucet body 1 is arranged using the vacant space below the discharge member 2 which is a mountain, so that the faucet as a whole is made compact and space-saving. Can also be achieved.

  Further, in addition to the two fixing screws 21 abutting symmetrically and firmly with respect to the cylindrical portion 26, fixing is also performed by screwing the female screw member 28 and the insertion screw 29. Even if the left and right end portions of the discharge port 8 are accidentally or intentionally pressed downward, the mounting posture of the discharge member 2 is not distorted by the pressing force.

  Further, a configuration is adopted in which a tapered groove 27 is provided in the cylindrical portion 26 of the discharge member 2 and the discharge member 2 is fixed to the faucet body 1 by bringing a fixing screw 21 into contact with the groove wall of the taper groove 27. Therefore, since the two screw holes 20 are provided, high-precision processing is not required, and the first water faucet can be manufactured at a low cost.

  The first water faucet can be appropriately changed in the constituent elements such as the material and shape of each member.

  For example, the first faucet is not limited to a so-called two-valve faucet having two flow rate adjusting units 4 and 7, and may be a single lever type faucet.

  Moreover, although the 1st water tap is installed in the bathtub B, you may install in the washstand, for example.

  Further, in the first faucet, the discharge member 2 is made of stainless steel, and since there is material strength, the intermediate portion of the discharge member 2 does not bend. However, the discharge member 2 may be made of resin. In this case, in order to prevent the intermediate portion of the discharge member 2 from being bent, a rib may be provided at an appropriate location.

  Further, the check valves 3 and 6 may not have a flow rate adjusting function.

  In the first faucet, a pair of screw holes 20 (fixing screws 21) are provided symmetrically, but only one of them may be provided, or three or more may be provided. .

  Next, a hot and cold water mixing faucet according to the second embodiment of the present invention will be described.

Some play (0.5 mm in this example) is provided between the surfaces. Further, the tip of the attachment member 68 is configured to abut on the stepped portion 74 of the eccentric tube main body 54. Therefore, the eccentric tube main body 54 inserted into the through hole 41 by the mounting member 68 fixed to the hole wall of the through hole 41 is rotatable around the axis of the eccentric tube 32 and has a reverse opening. 43 so that it does not come out of 43.

  Next, a method for attaching the hot and cold water mixing faucet will be described.

  (1) First, the eccentric tube 32 shown in FIG. 23 is assembled.

  That is, the seal member 61 is attached to each annular recessed portion 60 of the eccentric tube main body 54, and the seal member 65 is attached to each annular recessed portion 64 of the connection tool 56, and the connection tool is viewed from below the eccentric hole 53 in FIG. 56 is inserted upwards. At this time, an outer diameter portion 56a larger than the inner diameter of the small diameter portion 53a provided on one end (the upper end in FIG. 23) side of the eccentric hole 53 is projected on the outer peripheral surface of the connecting tool 56. The complete removal of the 56 from the upper side of the eccentric hole 53 is prevented by the engagement of the both 53a and 56a.

  (2) After that, the split ring 67 is attached to the male thread portion 57 of the connection tool 56 protruding above the eccentric hole 54, and the fixing nut 58 is screwed.

  (3) Subsequently, after attaching the attachment member 68 to the eccentric tube 32 shown in FIG. 23 to obtain the state shown in FIGS. 22 and 25A and 25B, the eccentric tube 32 is opened in the reverse direction. 43 is inserted into the through-hole 41, and the male threaded portion 69 of the mounting member 68 is screwed into the female threaded portion 72 of the through-hole 41, and the both 69 and 72 are fixed by an adhesive. That is, an adhesive is applied to the male screw portion 69 in advance.

  As a result, the eccentric tube main body 54 is held by the attachment member 68 so as to be able to rotate 360 ° around the axis of the eccentric tube 32 and so as not to come out from the reverse opening 43 side. As shown in FIG. 21, an outer diameter portion 54a larger than the inner diameter of the small diameter portion 41a provided on the distal end (lower end in FIG. 21) side of the through hole 41 is provided on the outer peripheral surface of the eccentric tube main body 54. Therefore, the eccentric tube main body 54 is prevented from being completely removed from the wall-facing opening 42 side by the engagement of both 41a and 54a.

  Similarly, the connection tool 56 is held by the eccentric tube main body 54 so as to be rotatable around the axis of the connection tool 56 so as not to come out from the reverse opening 43 side. Further, as shown in FIG. 21, a fixing nut 58 that contacts the rear end of the eccentric tube main body 54 is screwed into the male thread portion 57 of the connection tool 56, so that the connection tool 56 can be seen from the wall-facing opening 42 side. Complete removal is prevented by the engagement between the eccentric tube main body 54 and the fixing nut 58.

  (4) Next, each eccentric tube 32 inserted through the opening 43 in the reverse direction with respect to each through hole 41 is rotated around the central axis of the eccentric tube 32, and two eccentricities with respect to the hot water supply pipe P1 and the water supply pipe P2 are operated. Positioning is performed so that the two connection portions 55 and 55 provided at the tips of the pipes 32 and 32 can be connected, and the two connection portions 55 and 55 are connected to the hot water supply pipe P1 and the water supply pipe P2 ( Screw). In this example, the connecting portion 55 is a male screw, and the tip of the supply pipe P is a female screw to which the connecting portion 55 is screwed.

  In other words, the eccentric tube 32 inserted into the through hole 41 and not connected to the supply pipe P is rotatable around the central axis of the eccentric tube 32. Then, by rotating each eccentric tube 32 around the central axis of the eccentric tube 32, the distance between the two connection portions 55 and 55 can be changed. 26 is the maximum in the state shown in FIG. 26 and is the minimum in the state shown in FIG. In this example, as shown in FIG. 20, the positions are aligned at an intermediate distance.

  Further, the screwing of the connecting portion 55 to the supply pipe P after the positioning is performed in a state where a tool (not shown) engaging with the inner peripheral wall portion 66a (in this example, a hexagon wrench) is inserted into the recessed portion 66. This is done by turning. And when screwing the connection part 55 in the supply piping P, in order to prevent a water leak reliably, processing, such as winding a seal tape around the connection part 55, may be suitably performed.

  (5) Then, the fixing nut 58 screwed to the male threaded portion 57 provided at the rear end portion of the connector 56 is rotated, and the fixing nut 58 is brought into contact with the rear end of the eccentric tube main body 54. Let Thereby, the assembly of the eccentric tubes 32 and 32 to the faucet body 31 is completed (see FIG. 28A).

  (6) Finally, as shown in FIG. 28 (B), a removable cover 75 is attached to the faucet body 31 so that the eccentric tubes 32 and 32 are covered with the cover 75. This completes the installation of the hot and cold water mixing faucet.

  In the hot and cold water mixing faucet attached through the above steps (1) to (6), as shown in FIG. 25 (B), the outer communication portion 59 of the eccentric tube main body 54 and the inner communication portion 63 of the connector 56. Are in communication with each other. Accordingly, the hot water and water that have entered the eccentric pipes 32 and 32 from the hot water supply pipe P1 and the water supply pipe P2 pass through the hollow portion 62, the inner communication portion 63, and the outer communication portion 59 in this order, respectively, toward the outside of the eccentric tubes 32. And then flows into the faucet body 31.

  Then, the hot water that has reached the faucet body 31 from the hot water supply pipe P1 flows from the rear left lower part of the faucet body 31 toward the rear center lower part as shown by the broken line in FIG. (C) flows from the strainer 34 a into the check valve 34 (see FIG. 13B) inserted and fixed in the body member 40 from the left opening 44, and is led out above the check valve 34. Next, after flowing toward the upper left rear side of the faucet body 31 as shown by a broken line in FIG. 16C, the front (upper left upper side of the faucet body 31) as shown by a broken line in FIG. To the hot water mixing section 35 from the annular space 35a provided outside the hot water mixing section 35 shown in FIG. That is, the hot / cold water mixing unit 35 is provided on the front left upper portion of the faucet body 31.

  On the other hand, the water that has reached the faucet body 31 from the water supply pipe P2 flows from the rear right lower part of the faucet body 31 toward the rear center lower part, as shown by a one-dot chain line in FIG. 16 (C) flows from the strainer 34a into the check valve 34 (see FIG. 13 (B)) inserted and fixed in the body member 40 through the opening 44 on the right side, and is led out above the check valve 34. . Next, as shown by a one-dot chain line in FIG. 16 (C), after flowing toward the upper left part on the rear side of the faucet body 31, it heads forward (the upper left part on the front side of the faucet body 31), and FIGS. As shown by the alternate long and short dash line in (D), the hot water mixing section 35 is reached from the upper side of the hot water mixing section 35.

  Thereafter, hot water and water are appropriately mixed in the hot water / water mixing section 35, and then reach the flow rate adjustment section 36 provided at the upper front center of the faucet body 31.

  In the state where the flow rate adjustment unit 36 is switched to discharge water from the shower side, the hot water flows from the shower opening 47b of the flow rate adjustment unit 36 (see FIGS. 17A to 17C) to the outer peripheral side. Then, as shown by a two-dot chain line in FIG. 12, it flows from the front center upper part of the faucet body 31 toward the front center lower part, and passes through the shower elbow 37 and the shower hose 38, and then the hand shower head 39 (see FIG. 9). ).

  On the contrary, in a state where the flow rate adjusting unit 36 is switched so as to discharge water from the discharge member (calant) 33 side, the hot water is supplied to the curan opening 47a of the flow rate adjusting unit 36 (FIGS. 17A to 17C). (See FIG. 13, FIG. 13 (A), FIG. 15 (D), and FIG. 16 (C) as shown by dotted lines (FIG. 13 (B) and FIG. 16 (A). )), And flows from the front center upper part of the faucet body 31 toward the rear left upper part, and is discharged from the discharge port 8 through the connecting pipe 18 and the discharge member 33.

  And in the 2nd water faucet, unlike the conventional tap water mixing faucet, the eccentric pipes 32 and 32 are not assembled | attached to the back side (wall W side) of the faucet main body 31, but the faucet main body 31 is penetrated. Since the eccentric tubes 32 and 32 are assembled in such a state, the protrusion of the wall W of the faucet body 31 to the front side can be minimized, and space saving can be achieved.

  Moreover, in the second faucet, the interior of the faucet body 31 is skillfully partitioned, so that the faucet body 31 and further the entire faucet can be made compact. That is, the hot water / water mixing unit 35 and the flow rate adjusting unit 36 that are installed in the front upper part of the faucet body 31 from the eccentric tubes 32 and 32 assembled at the lower part of the faucet body 31, and the flow rate adjusting unit 36. Both the hot and cold water flow paths leading to the discharge member 33 connected to the rear surface of the faucet body 31 from the faucet body 31 are provided by partitioning the rear upper part of the faucet body 31. The increase in size is avoided.

  Further, in the second faucet attachment method, for example, if the above steps (1) to (3) are performed in advance in a factory or the like, it can be started from the alignment of the step (4) at the construction site. The mounting workability can be remarkably improved.

  Furthermore, the effect produced by the first faucet can also be produced by the second faucet.

  In addition, the second faucet can also be appropriately changed in the constituent elements such as the material and shape of each member as in the first faucet.

  For example, in the second faucet, the wall W is used as a bathroom wall, but the wall W is not limited to a wall extending in a substantially vertical direction so as to partition a room (room) in this way. Or a wall that forms a housing, or a wall that extends in a substantially horizontal direction, such as a wall that forms the upper surface of a washstand.

  The faucet body 31 is not limited to the one having the above-described configuration, and the faucet body 31 having various configurations can be employed. Furthermore, the position where the through holes 41 are provided is not limited to the lower portion of the body member 40 and can be set as appropriate.

  Further, instead of a configuration in which the connecting portion 55 is a male screw and the tip of the supply pipe P is a female screw, a configuration in which the connecting portion 55 is a female screw and the tip of the supply pipe P is a male screw may be employed.

  Further, the fixing nut 58 may not be used.

  In addition, the number of holes 59a constituting the outer communication portion 59 and the holes 63a constituting the inner communication portion 63 are not limited to the above-described configuration, and the number and arrangement thereof can be changed as appropriate.

  Further, when the attachment member 68 is used, the male screw portion 69 may be screwed without being bonded to the female screw portion 72 of the through hole 41, and the attachment member 68 may not be used. However, it is preferable to use at least one of the mounting member 68 and the fixing nut 58 in terms of workability and safety, and using both of them is more suitable in terms of workability and safety. Needless to say.

  Further, the inner peripheral wall portion 66a is not limited to a regular hexagonal shape, and may be, for example, an elliptical shape or another regular polygonal shape. In this case, as a tool used in the step (4), a tool that engages with the inner peripheral wall portion 66a may be used.

  In addition, the connection tool 56 is provided with a recess 66, and in the step (4), an appropriate tool is inserted into the recess 66 to rotate the connection tool 56. For example, the connection tool 56 is replaced with the recess 66. A non-circular convex portion may be provided, and the connecting tool 56 may be rotated in the step (4) using an appropriate tool that engages with the convex portion.

  Moreover, you may perform the said process (2) after a process (3).

  Further, FIGS. 14, 18A and 18B show the left cylinder portion 26 closed by the plug member 26a. The cylinder member 26 is molded so as not to be opened and the plug member 26a is formed. May be omitted.
