Description

[Technical Field]

[0001] The present invention relates to a faucet device, and more particularly to a faucet device used in a bathtub or the like. [Background technology]

[0002] BACKGROUND ART Conventionally, a hot and cold water mixing faucet is known in which a water passage member, through which a water passage through which hot and cold water flows, is embedded inside an outer casing member, as described in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. CN205090047 Summary of the Invention [Problem to be solved by the invention]

[0004] In the hot and cold water mixing faucet of Patent Document 1, the water pressure acting on the water-passing member also acts on the outer casing member, so there is a possibility that the outer casing member of the faucet body will come off the wall fixing member with force while the user is using the faucet device.

[0005] The inventors have conducted extensive research and have solved the problem of water pressure acting on the water-permeable member acting on the outer casing member, making it possible to obtain a faucet device in which the outer casing member of the faucet body does not come off the wall fixing member forcefully while the user is using the faucet device.

[0006] Therefore, the present invention has been made to solve the problems of the prior art, and has an object to provide a water faucet device with higher safety. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the faucet device of the present invention is characterized by having a faucet body, a wall fixing member for fixing the faucet body to a wall, an outer casing member that forms the outer casing of the faucet body, a water-permeable member provided inside the outer casing member, a connecting member that connects the wall fixing member and the outer casing member along the longitudinal direction, and a water pressure transmission member that is inserted into the gap between the connecting member and the water-permeable member and transmits the water pressure acting on the water-permeable member to the connecting member. In the present invention configured in this manner, the water pressure acting on the water-permeable member is transmitted to the connecting member by the water pressure transmission member, thereby preventing water pressure from acting on the outer casing member, thereby preventing the outer casing member of the faucet body from coming off the connecting member with force while the user is using the faucet device.

[0008] In the present invention, preferably, the water pressure transmission member has a flange portion extending radially outward, and this flange portion is formed on the upstream side of the water flow direction of the water pressure transmission member and is positioned so as to be able to come into contact with the upstream surface of the connecting member. In a water faucet device configured in this manner, the water pressure transmission member has a flange extending radially outward, and this flange is formed on the upstream side of the water pressure transmission member in the water flow direction and is positioned so as to contact the upstream surface of the connecting member. Therefore, even if water pressure acts on the water-passing member, this water pressure causes the flange of the water pressure transmission member to press the connecting member toward the downstream side, so that the water pressure can be more reliably transmitted to the connecting member. As a result, according to the present invention, it is possible to more reliably prevent the outer member of the faucet body from suddenly coming off the wall fixing member while the user is using the water faucet device.

[0009] In the present invention, preferably, the water-permeable member is bent at approximately a right angle in the downstream direction within the outer casing member, and the gap between the inner surface of the outer casing member and the outer surface of the part of the water-permeable member bent at approximately a right angle downstream is formed larger than the gap along the flow direction between the connecting member and the water pressure transmission member. In the present invention configured in this manner, the gap between the inner surface of the outer casing member and the outer surface of the part of the water-permeable member bent at approximately a right angle downstream is formed larger than the gap along the flow direction between the connecting member and the water pressure transmission member, thereby preventing the water-permeable member from coming into forceful contact with the outer casing member when water is passing through.

[0010] In the present invention, a seal member is preferably provided along the circumferential direction between the outer diameter side surface of the water-passing member and the inner diameter side surface of the connecting member. In the present invention configured in this manner, a sealing member is provided circumferentially between the outer diameter side of the water-passing member and the inner diameter side of the connecting member, and this sealing member can absorb tolerances along the longitudinal direction of the connecting member and the water pressure transmission member, making it easier to design the faucet device.

[0011] In the present invention, preferably, the water pressure transmission member has its inner diameter side surface threadedly connected to the outer diameter side surface of the water-passing member, and the surface of the connecting member that contacts the water pressure transmission member has a tapered shape that extends obliquely from the outer diameter side to the inner diameter side toward the downstream side. In the present invention formed in this manner, the surface of the connecting member that comes into contact with the water pressure transmission member has a tapered shape that extends diagonally downstream from the outer diameter side to the inner diameter side.Therefore, even if the water passage member moves in a twisting manner when water is passing through, the water pressure transmission member can move in the flow direction along the tapered surface of the connecting member, thereby preventing the threads of the screw connection from being crushed. [Effects of the Invention]

[0012] According to the water faucet device of the present invention, a water faucet device with higher safety can be provided. [Brief explanation of the drawings]

[0014] A water faucet device according to an embodiment of the present invention will now be described with reference to the drawings. First, the overall structure of a water faucet device according to an embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a perspective view of a water faucet device according to an embodiment of the present invention, and Figure 2 is a side view of a water faucet device according to an embodiment of the present invention. Figure 3 is a top cross-sectional view of a water faucet device according to an embodiment of the present invention as seen along line III-III in Figure 2.

[0015] As shown in FIGS. 1 to 3, a faucet device 1 according to an embodiment of the present invention comprises a faucet body 2, and a cold water inlet 4 and a hot water inlet 6 for attaching the faucet body 2 to a wall. The faucet body 2 is equipped with a spout 8 that spouts hot and cold water, and is able to spout hot and cold water from a spout 10 provided at the tip of the spout 8. Furthermore, the faucet body 2 is equipped with a single-lever cartridge (not shown) that mixes hot and cold water and stops the water from flowing, and a single lever 12 for operating this single-lever cartridge, and the water flow can be stopped by moving this lever 12 up and down, and the hot and cold water can be mixed by moving the lever 12 sideways, allowing the temperature of the water to be adjusted.

[0016] The above-mentioned water-side inlet 4 is connected to a water pipe so that tap water at room temperature flows in, and the hot water-side inlet 6 is connected to a water heater so that hot water at a set temperature flows in.

[0017] Here, since the cold water side inlet section 4 and the hot water side inlet section 6 have the same structure, only the hot water side inlet section 6 will be explained below with reference to Figures 4 to 6. Figure 4 is an enlarged cross-sectional view of part X in Figure 3, Figure 5 is an exploded view of parts that form the hot water side inlet section shown in Figure 3, and Figure 6 is an enlarged cross-sectional view of part Y in Figure 4.

[0018] As shown in Figures 4 to 6, first, the hot water side inlet section 6 is provided with a hot water side leg member 20, which is a water supply joint, and this hot water side leg member 20 is inserted into the wall and connected to the water pipe. This hot water side leg member 20 is inserted into a hole in a cover member 22, and the part of the hot water side leg member 20 facing the wall is covered so that it cannot be seen from the outside. Furthermore, a filter-equipped packing 24 is attached to the tip side (downstream side) of the hot water side leg member 20, which serves as both a seal member and a filter between the hot water side leg member 20 and the connecting member 34.

[0019] Next, the faucet body 2 has an outer casing member 26, which is made of zinc. A resin water-permeable member 28 is fitted inside the outer casing member 26. A water passage is formed in the water-permeable member 28, allowing hot water to flow through it. A water-permeable hose 30 is connected to the water-permeable member 28, and the hot water that passes through the water-permeable hose 30 is mixed with water that has flowed in from the water-side inlet 4 on the downstream side, and this hot and cold water passes through the spout 8 and is discharged from the water outlet 10.

[0020] Next, the outer casing member 26 of the faucet body 2 is connected to the fixing member 32 along the longitudinal direction by a connecting member 34. The hot water side leg member 20 is fixed to the wall (water pipe). The fixing member 32 is screwed to the hot water side leg member 20, and the faucet body 2 is attached to the hot water side leg member 20 by rotating the fixing member 32. The cover member 22 has an internal thread on the inner diameter, and this internal thread can be connected to the external thread of the hot water side leg member 20. Therefore, by rotating the cover member 22, the gap with the wall surface can be filled. The fixing member 32, the connecting member 34, and the water pressure transmission member 36 described later are made of stainless steel (SUS304).

[0021] Here, an inner recess 32a is formed on the tip side (downstream side) of the fixing member 32, and an outer protrusion 34a is formed on the rear end side of the connecting member 34, with the outer protrusion 34a of the connecting member 34 fitted into the inner recess 32a of the fixing member 32 so as to prevent movement in the longitudinal and radial directions. Furthermore, the rear end side (upstream side) of the outer casing member 26 and the tip side (downstream side) of the connecting member 34 are screw-coupled. In this way, the outer casing member 26 and the fixing member 32 are connected by the connecting member 34.

[0022] Next, a water pressure transmission member 36 is provided inside the connecting member 34. A flange portion (outer convex portion) 36a is formed on the rear end side (upstream side) of this water pressure transmission member 36, and this flange portion 36a is fitted into an inner concave portion 34b on the rear end side (upstream side) of the connecting member 34, preventing the water pressure transmission member 36 from moving in the longitudinal and radial directions. In addition, the tip side (downstream side) of the water pressure transmission member 36 is screw-connected to the outer surface 28a of the water passage member 28. A small gap C is formed between the inner surface of the connecting member 34 and the outer surface of the water pressure transmission member 36 .

[0023] Next, a ring-shaped seal member 40 is attached between the inner surface of the connection member 34 and the outer surface of the water-passing member 28 .

[0024] The process of assembling the outer casing member 26 of the faucet body 2 to the hot water side leg member 20 will be described. First, the filter packing 24 and the cover member 22 are pre-assembled to the hot water side leg member 20, with the filter packing 24 and cover member 22 placed between the connecting member 34 and the hot water side leg member 20. In this state, the fixing member 32, connecting member 34, water pressure transmission member 36, filter packing 24, and cover member 22 are attached to the tip side (downstream side) of the hot water side leg member 20. Specifically, as shown in Figure 4, the water-permeable member 28 is housed inside the outer casing member 26, and then the fixing member 32 is inserted between the outer casing member 26 and the connecting member 34, and the outer casing member 26 and the connecting member 34 are screwed together. The inner diameter portion of the connecting member 34 has a hexagonal hole shape, so that it can be rotated using a hexagonal wrench or the like. The water pressure transmission member 36 is threadedly connected to the water passage member 28 from the upstream side of the threaded connection member 34. The water pressure transmission member 36 also has a hexagonal hole formed therein. At this time, the outer convex portion 34a formed on the rear end side of the connecting member 34 is fitted into the inner recess 32a formed on the tip side (downstream side) of the fixing member 32, and further, an inner recess 34b is also formed on the rear end side (upstream side) of the connecting member 34, and a flange portion (outer convex portion) 36a formed on the rear end side (upstream side) of the water pressure transmission member 36 is fitted into this inner recess 34b.

[0025] Next, in this state, as shown in Figure 4, the connecting member 34 is inserted into the gap between the outer casing member 26 and the water-permeable member 28. At this time, the outer casing member 26 and the connecting member 34 are screwed together to prevent the connecting member 34 from rotating. In addition, a seal member 38 is provided between the outer diameter side surface of the water-permeable member 28 and the inner diameter side surface of the connecting member 34 along the circumferential direction.

[0026] In addition, the water-permeable member 28 bends at approximately a right angle toward the downstream side inside the outer casing member 26, and the gap A between the inner surface 26a of the outer casing member 26 and the outer surface 28a of the part of the water-permeable member 28 bent at approximately a right angle toward the downstream side is formed larger than the gap B along the flow direction between the connecting member 34 and the flange portion 36a of the water pressure transmission member 36.

[0027] By providing such connecting member 34 and water pressure transmission member 36, water pressure acting on water-permeable member 28, which is the primary flow path, is transmitted to water pressure transmission member 36, and then from this water pressure transmission member 36 to connecting member 34, and further to fixing member 32, without being transmitted to outer casing member 26. With this configuration, outer casing member 26 of faucet body 2 will not come off forcefully from connecting member 34 while a user is using faucet device 1. Furthermore, because water pressure does not act on outer casing member 26, zinc can be used as the material for outer casing member 26. Although zinc has higher dimensional accuracy than copper alloys, it is more susceptible to corrosion than copper alloys and is expected to weaken bonds with other members.

[0028] Next, a water faucet device according to a modified embodiment of the present invention will be described with reference to Figures 7 to 9. Figure 7 is an enlarged cross-sectional view of part X, corresponding to Figure 3, of a water faucet device according to a modified embodiment of the present invention, Figure 8 is an exploded view of parts that form the hot water side inlet of the water faucet device according to the modified embodiment of the present invention shown in Figure 7, and Figure 9 is an enlarged cross-sectional view of part Z in Figure 7.

[0029] In this modified example, only the parts that differ from the example shown in Figures 4 to 6 will be described. In this modified example, a tapered surface 50a that extends obliquely downstream from the outer diameter side to the inner diameter side is formed on the inner surface on the rear side (upstream side) of the connecting member 50. In addition, a flange portion 52a is formed on the rear side (upstream side) of the water pressure transmission member 52.

[0030] In this modified example, even when water pressure is applied when water is passing through, the flange portion 52a of the water pressure transmission member 52 pushes the tapered surface 50a of the connecting member 50 in the direction of the water flow, while being able to slide circumferentially.

[0031] Next, the effects and advantages of the faucet device according to the above-described embodiment and its modified example of the present invention will be described.

[0032] In the faucet device 1 according to an embodiment of the present invention, the water pressure transmission member 36 transmits the water pressure acting on the water-permeable member 28 to the connecting member 34, and does not transmit it to the outer casing member 26, thereby preventing the outer casing member 26 of the faucet body 2 from coming off the connecting member 34 with force while the user is using the faucet device 1.

[0033] In the faucet device 1 according to the embodiment of the present invention, the water pressure transmission member 36 has a flange 36a extending radially outward, and this flange 36a is formed on the upstream side of the water flow direction of the water pressure transmission member 36 and is positioned so as to contact the upstream surface of the connecting member 34. Therefore, even if water pressure acts on the water-permeable member 28, this water pressure causes the flange 36a of the water pressure transmission member 36 to press the connecting member 34 downstream, so that the water pressure can be more reliably transmitted to the connecting member 34. As a result, according to the present embodiment, it is possible to more reliably prevent the outer member 26 of the faucet body 2 from forcefully coming off the wall fixing member 32 while the user is using the faucet device 1.

[0034] In the faucet device 1 according to an embodiment of the present invention, the gap A between the inner surface of the outer casing member 26 and the outer surface of the portion of the water-permeable member 28 bent at approximately a right angle downstream is formed larger than the gap B along the flow direction between the connecting member 34 and the water pressure transmission member 36, thereby preventing the water-permeable member 28 from coming into forceful contact with the outer casing member 26 when water is passing through.

[0035] In the faucet device 1 according to an embodiment of the present invention, a sealing member 38 is provided circumferentially between the outer diameter side surface of the water-passing member 28 and the inner diameter side surface of the connecting member 34, and this sealing member 38 can absorb tolerances along the longitudinal direction of the connecting member 34 and the water pressure transmission member 36, making it easier to design the faucet device 1.

[0036] In the faucet device 1 according to an embodiment of the present invention, the surface 50a of the connecting member 50 that comes into contact with the water pressure transmission member 52 has a tapered shape that extends diagonally downstream from the outer diameter side to the inner diameter side. Therefore, even if the water-passing member 28 moves in a twisting manner when water is passing through, the water pressure transmission member 52 can move in the flow direction along the tapered surface 50a of the connecting member 50, thereby preventing the threads of the screw connection from being crushed.
