Description

[Technical Field]

[0001] The present invention relates to a faucet device, and more particularly to a faucet device used for a single faucet for a bathroom sink, etc. [Background technology]

[0002] Single-piece faucet devices used in washbasins have been known for some time, and in these single-piece faucet devices, the inside of the outer casing that constitutes the faucet body is used directly as the water flow path. Also known are faucet devices in which a separate component (a water supply joint) that forms the water flow path is attached to the inside of the outer casing.

[0003] In particular, as described in Patent Document 1, a faucet device is also known in which a separate member is provided within an outer casing member to form a water passage, and in order to attach this separate member to the outer casing member, the separate member is fixed to the outer casing member with a screw portion on the water discharge side. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] CN 214143941 U Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, copper alloys, which have traditionally been used in the bodies of faucets, have the advantages of being highly rigid and resistant to corrosion, but attempts have been made to manufacture faucets using zinc for the body, which has various other advantages, such as the ability to achieve higher dimensional accuracy. When zinc is used, it is more susceptible to corrosion than conventional copper alloys, so if zinc is used for the outer casing of the faucet body, it is necessary to install a water-permeable member (water supply joint) made of resin or the like inside the outer casing to prevent water from coming into direct contact with the outer casing, and to form a flow path within this water-permeable member.

[0006] However, when attaching a water-permeable member to the water-spout side of the outer casing member, if the water-permeable member is fixed using the threaded portion of the outer casing member, as described in Patent Document 1, the tightening process takes time, and furthermore, due to the structure of the water-spout side of the outer casing member, it may not be possible to form a threaded portion around the entire circumference of the outer casing member, and various problems arise when using threaded portions.

[0007] Therefore, the present invention has been made to solve the problems associated with the prior art, and aims to provide a faucet device that allows the water supply fitting that forms the water flow path in the outer casing member to be easily fixed with a single touch. [Means for solving the problem]

[0008] In order to achieve the above object, the water faucet device of the present invention comprises an outer casing member that forms the outer casing of the water faucet device, a water supply joint that is provided inside the outer casing member and forms a water flow path, an aerator cap attached to the water discharge side of the water supply joint, a fixing ring that is arranged inside the outer casing member above the water discharge side of the water supply joint, and a joint presser that is arranged inside the outer casing member below the water discharge side of the water supply joint, and a recess that faces rearward from the tip is formed on the inside of the water discharge side of the outer casing member, and the fixing ring has first and second protrusions that protrude downward on the outer periphery side, The first and second convex portions of the fitting are first and second convex portions that are spaced apart circumferentially by a predetermined distance, and the joint holder is provided with a convex portion that protrudes toward the outer periphery and extends circumferentially.When the joint holder is rotated, one end of the convex portion of the joint holder contacts and passes over the inner surface of the first convex portion of the fixing ring, and then abuts against the second convex portion, stopping the rotation of the joint holder.At this time, the other end of the convex portion of the joint holder abuts against the first convex portion, and further, the convex portion of the joint holder engages with the underside of the concave portion of the outer casing member, thereby fixing the water supply joint to the outer casing member. In the present invention configured as described above, when attaching the water supply joint to the outer casing member, a fixing ring is provided inside the outer casing member at the top of the water supply joint on the water discharge side, and a joint presser is provided inside the outer casing member at the bottom of the water supply joint on the water discharge side, and a recess is formed on the inside of the outer casing member on the water discharge side, facing rearward from the tip, and the fixing ring has first and second protrusions that protrude downward on the outer periphery, and these first and second protrusions are spaced apart in the circumferential direction by a predetermined distance, and the water supply joint is attached to the outer casing member. The hand clamp has a convex portion that protrudes outward and extends circumferentially, and when the joint clamp is rotated, one end of the first convex portion of the joint clamp comes into contact with and passes over the inner peripheral surface of the first convex portion of the fixing ring, then comes into contact with the second convex portion, stopping the rotation of the joint clamp, at which point the other end of the convex portion of the joint clamp comes into contact with the first convex portion, and further, the convex portion of the joint clamp engages with the underside of the recess in the outer casing member, allowing the water supply joint to be fixed to the outer casing member with one touch, thereby shortening assembly time compared to conventional screw-type fixing structures, etc. Furthermore, even if a mistake is made, there is no need to destroy and disassemble the parts, and they can be disassembled using a dedicated tool and reassembled.

[0009] In the present invention, the recessed portion of the outer shell member, the outer peripheral surface of the fixing ring, and the protruding portion extending in the circumferential direction of the joint presser are preferably fan-shaped. In the present invention configured in this manner, the water supply joint can be fixed to the outer casing member by rotating the joint holder by one revolution or less.

[0010] In the present invention, the inner circumferential surface of the first convex portion of the fixing ring and the inner circumferential surface of the second convex portion are preferably formed in sector shapes with the same radius of curvature when viewed from above. According to the present invention configured in this manner, the inner surface of the first convex portion of the fixing ring and the inner surface of the second convex portion are formed into sector shapes with the same radius of curvature when viewed from above, which allows the joint clamp to rotate smoothly and requires less force to rotate the joint clamp. [Effects of the Invention]

[0011] According to the water faucet device of the present invention, the water supply joint that forms the water flow path in the outer shell member can be easily fixed with a single touch. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] A water faucet device according to an embodiment of the present invention will now be described with reference to the drawings. First, the basic structure of the water faucet device will be described with reference to Figures 1 and 3. Figure 1 is a perspective view showing a water faucet device according to an embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view showing a water faucet device according to an embodiment of the present invention, and Figure 3 is an enlarged cross-sectional view of the water discharge side portion of Figure 2.

[0014] As shown in Figures 1 and 2, a faucet device 1 according to an embodiment of the present invention is a single-use washbasin faucet that is attached to a washbasin, and this faucet device 1 includes a faucet body 2. The faucet body 2 houses a single valve 4 that mixes hot and cold water and stops the water discharge, and this single valve 4 is supported by a base 5. A cold water pipe 6 and a hot water pipe 8 are connected to the base 5 from below, and cold water and hot water are supplied to the single valve 4 from the cold water pipe 6 and the hot water pipe 8 through the base 5.

[0015] Next, a single lever 10 for operating the single valve is attached to the single valve 4. This lever 10 is rotated left and right to mix hot and cold water, and moved up and down to stop the water discharge.

[0016] The faucet body 2 also has an outer casing member 12, which is made of zinc. A water supply fitting 14 is attached to the inside of this outer casing member 12, forming a water flow path for hot and cold water flowing out from the single valve 4. This water supply fitting 14 is made of resin. A foam cap 16 is attached to the tip (spout side) of this water supply fitting 14.

[0017] As shown in Figure 3, a recess 18 facing rearward from the tip is formed on the inside of the water-spouting side of the outer shell member 12. This recess 18 is fan-shaped when viewed from above, and is formed only on the water-spouting side. A fixing ring 20 is attached to the upper part of this recess 18 and to the upper part of the water-spouting side of the water supply joint 14. This fixing ring 20 is fan-shaped with an open rear side, as will be described in detail later.

[0018] A joint holder 22 is attached to the lower part and side of the water discharge side of the water supply joint 14 inside the outer shell member 12. This joint holder 22 is also cylindrical, as will be described in detail later. In this way, the water supply joint 14 is fixed to the outer shell member 12 by the fixing ring 20 and the joint holder 22. This point will also be described in detail later.

[0019] Next, the main components that make up the faucet device 1 will be described with reference to Figures 4 to 9. Figure 4 is a perspective view of the outer casing member of a faucet device according to an embodiment of the present invention, viewed obliquely from below, Figure 5 is a perspective view of the water supply joint, viewed obliquely from above, Figure 6 is a perspective view of the fixing ring, viewed obliquely from above, Figure 7 is a bottom view of the fixing ring, viewed from below, Figure 8 is a perspective view of the joint holder, viewed obliquely from above, and Figure 9 is a perspective view of the joint holder, viewed obliquely from below.

[0020] First, as shown in Figure 4, the outer shell member 12 is hollow and made of zinc. The outer shell member 12 has a body portion 12a that houses the single valve 4 described above, and a spout portion 12b that houses the water supply joint 14 inside.

[0021] Next, as shown in Figure 5, the water supply fitting 14 forms a water flow path inside. The water supply fitting 14 is made of resin. The water supply fitting 14 has two protrusions 14a extending laterally from both sides of approximately the center in the longitudinal direction. These protrusions 14a abut against the inner surface of the outer casing member 12, preventing the water supply fitting 14 from moving within the outer casing member 12. In addition, a storage section 14b for storing the foam cap 16 is provided on the water discharge side of the water supply fitting 14.

[0022] Next, as shown in Figure 6, fixing ring 20 is fan-shaped with an open rear side and is made of resin. Two cylindrical protrusions 20a extending upward are provided near the opening on the rear side of fixing ring 20. These protrusions 20a are inserted into recesses (not shown) provided on the inner surface of outer shell member 12, thereby preventing fixing ring 20 from rotating.

[0023] 6 and 7, a first protrusion 24 and a second protrusion 26 that protrude downward are provided on the outer circumferential side of the fixing ring 20. The first protrusion 24 and the second protrusion 26 are spaced apart in the circumferential direction by a predetermined distance L1. The inner circumferential surfaces 24a and 26a of the first protrusion 24 and the second protrusion 26 are arc-shaped with a radius r1.

[0024] Next, as shown in FIGS. 8 and 9, the joint retainer 22 is cylindrical and made of resin. The joint retainer 22 has a convex portion 28 that projects outward on the outer peripheral side and extends in the circumferential direction. This convex portion 28 is fan-shaped in top view, and the circumferential length (distance) of the convex portion 28, that is, the length from its front end portion 28b to the rear end portion 28c, is the same L1 as the separation distance between the first convex portion 24 and the second convex portion 26 of the above-described fixed ring 20. The outer peripheral surface 28a of the convex portion 28 of the joint retainer 22 is formed with a radius r2 (see FIG. 7). The radius r2 of this outer peripheral surface 28a is slightly larger than the radii r1 of the inner peripheral surfaces 24a and 26a of the first convex portion 24 and the second convex portion 26 of the above-described fixed ring 20, and there is a relationship of r1 < r2.

[0025] Note that a support convex portion 30 that projects inward on the inner peripheral side and extends in the circumferential direction is formed at the lower portion of the joint retainer 22. The lower portion of the water supply joint 14 is supported by the support convex portion 30 of the joint retainer 22 (see FIG. 3).

[0026] Next, the assembly process of the faucet device 1 will be described with reference to FIG. 10. FIG. 10 is a diagram showing the overall assembly process of the faucet device according to the embodiment of the present invention, and FIG. 11 is a diagram showing the latter half of the assembly process.

[0027] As shown in FIG. 10, first, in step (a), the pedestal 5 and the like are inserted into the outer member 12. Next, the fixed ring 20 is attached into the outer member 12. Next, the rear end side (upstream side) of the water supply joint 14 is connected to the single valve 4. Next, in step (b), the joint retainer 22 is rotated and attached, the water supply joint 14 is attached to the outer member 12, and the assembly process is completed.

[0028] Next, the above-described step (b) will be specifically described with reference to FIG. 11. In step (b1), the joint retainer 22 is inserted from below with respect to the fixed ring 20. At this time, the convex portion 28 of the joint retainer 22 is located outside the circumferential direction of the first convex portion 24 and the second convex portion 26 of the fixed ring 20.

[0029] Next, the joint holder 22 is rotated approximately half a turn (120 degrees) clockwise when viewed from above. By rotating the joint holder 22, the process proceeds to step (b2). In step (b2), the protrusion 28 of the joint holder 22 is positioned in the space formed between the first protrusion 24 and the second protrusion 26 of the fixing ring 20.

[0030] The state during the transition from step (b1) to step (b2) will be described in more detail. In step (b1) of fixation, when the joint holder 22 is rotated, first, the outer peripheral surface 28a of the circumferential tip 28b of the protrusion 28 of the joint holder 22 comes into contact with and moves against the inner peripheral surface 24a of the fixing ring 20. At this time, as shown in Fig. 7, the radius r2 of the outer peripheral surface 28a of the protrusion 28 of the joint holder 22 is slightly longer than the radius r1 of the inner peripheral surface 24a of the first protrusion 24 of the fixing ring 20, so the protrusion 28 of the joint holder 22 moves while coming into contact with the inner peripheral surface 24a of the first protrusion 24 of the fixing ring 20 while deforming itself inward.

[0031] When the entire circumferential portion of the convex portion 28 of the joint holder 22 has passed over the inner peripheral surface 24a of the first convex portion 24 of the fixing ring 20, the tip end 28b of the convex portion 28 of the joint holder 22 abuts against the second convex portion 26 of the fixing ring 20. Also, at this time, the rear end 28c of the convex portion of the joint holder 22 abuts against the first convex portion 24 of the fixing ring 20. Furthermore, at this time, as shown in FIG. 3, the convex portion 28 of the joint holder 22 rides up onto the lower surface 18a of the concave portion 18 of the outer casing member 12, preventing the joint holder 22 from falling downward. As a result, during the assembly process, the convex portion 28 of the joint holder 22 is prevented from moving circumferentially by the first convex portion 24 and the second convex portion 26 of the fixing ring 20, and further, since the convex portion 28 of the joint holder 22 is positioned within the concave portion 18 of the outer casing member 12, it is also prevented from falling downward.

[0032] Next, the effects of the water faucet device 1 according to the embodiment of the present invention described above will be described. First, in the faucet device 1 according to the embodiment of the present invention, when the water supply joint 14 is attached to the outer casing member 12, a fixing ring 20 is provided inside the outer casing member 12, above the water supply joint 14 on the water discharge side, and a joint presser 22 is provided inside the outer casing member 12, below the water supply joint 14 on the water discharge side. A recess 18 is formed on the inside of the outer casing member 12 on the water discharge side, facing rearward from the tip. The fixing ring 20 has a first protrusion 24 and a second protrusion 26 that protrude downward on the outer periphery, and these first protrusion 24 and second protrusion 26 are spaced apart in the circumferential direction by a predetermined distance L1. The fitting 22 has a protrusion 28 that protrudes outward and extends circumferentially, and when the fitting holder 22 is rotated, the tip 28b of the first protrusion 24 of the fitting holder 22 comes into contact with and passes over the inner peripheral surface 24a of the first protrusion 24 of the fixing ring 20, and then comes into contact with the second protrusion 26, stopping the rotation of the fitting holder 22, at which point the other end 28c of the protrusion 28 of the fitting holder 22 comes into contact with the first protrusion 24, and further, the protrusion 28 of the fitting holder 22 engages with the underside 18a of the recess 18 of the outer casing member 12, thereby allowing the water supply fitting 14 to be fixed to the outer casing member 12 with a single touch, thereby shortening assembly time compared to conventional screw-type fixing structures, etc. Furthermore, even if an error is made in the work, there is no need to destroy and disassemble the parts, and the parts can be disassembled using a dedicated tool and reassembled.

[0033] Secondly, according to the water faucet device 1 according to the embodiment of the present invention, the water supply joint 14 can be attached to the outer casing member 12 by rotating the joint holder 22 by one rotation or less.

[0034] Thirdly, according to the faucet device 1 of the embodiment of the present invention, the inner surface 24a of the first convex portion 24 of the fixing ring 20 and the inner surface 26a of the second convex portion 26 are formed into a fan shape with the same radius of curvature when viewed from above, which allows the joint clamp 22 to rotate smoothly and requires less force to rotate the joint clamp 22.
