Description

Technical Field

[0001] The present invention relates to a faucet device that prevents water from entering valves and the like by covering the periphery of a valve that opens, closes, and switches a water discharge passage with a spout and a decorative cover.

Background Art

[0002] Conventionally, as a technology related to such a faucet device, for example, there is one shown in Patent Document 1 (see paragraphs

[0009] to

[0011] and FIGS. 2, 5, etc.).

[0003] The faucet S according to Patent Document 1 includes a faucet body 20, a valve device 50, and a lever handle 30 for operating the valve device 50. The lever handle 30 includes a handle body 31 having a recess that opens downward, and a mounting portion 32 provided substantially cylindrically inside the recess. This mounting portion 32 is inserted and connected to a transmission member 55 that operates the valve device 50.

[0004] The mounting portion 32 is provided with a through hole, and by screwing and mounting a retaining member 85 on the outer surface portion of the mounting portion 32, the tip of the retaining member 85 fits into the transmission member 55 and the mounting portion 32 is fixed.

[0005] In this faucet, a cover member 70 is disposed around the mounting portion 32. The cover member 70 is supported by a fixing member 60 in a state where it can move downward using an elastic support member 80. Normally, the cover member 70 conceals the through hole. On the other hand, when the cover member 70 is moved downward against the biasing force of the elastic support member 80, the through hole appears.

[0006] According to the description of Patent Document 1, a sealing member for sealing the through hole becomes unnecessary, and the attachment and detachment of the lever handle 30, and the maintenance of the lever handle 30 or the faucet S can be performed without trouble. Also, the components of the lever handle 30 are reduced and the structure is simplified. Furthermore, it is said that the aesthetics of the lever handle 30 and the faucet S are improved.

Prior Art Documents

[0007] [Patent Document 1] Japanese Patent Publication No. 2008-31670 [Overview of the project] [Problems that the invention aims to solve]

[0008] In the faucet device described in Patent Document 1, the cover member 70 is biased by the elastic support member 80 to move closer to the lever handle 30. This is to conceal the retaining member 85 for the lever handle 30, and does not prevent water from entering through the gap between the bottom of the lever handle 30 and the cover member 70. As shown in Figure 5 of the prior art, a large circular opening is provided in the center of the cover member 70 so that the mounting portion 32 can swing and rotate. Therefore, water can easily enter through the gap between the edge of the opening and the mounting portion 32.

[0009] In this faucet device, there is no apparent design concept to address water ingress from below the lever handle 30. Furthermore, it is believed that other faucet devices also do not have any special measures to address water ingress from above the cover component.

[0010] Thus, conventional faucet devices still have room for improvement in ensuring waterproofing at the top of the spout, and there is a need for faucet devices with a rational waterproofing mechanism. [Means for solving the problem]

[0011] (Feature composition) The characteristic configuration of the faucet device according to the present invention is: A valve equipped with a valve lever for opening and closing / switching the water discharge flow path, A valve case housing the aforementioned valve, A valve fixing member for fixing the valve to the valve case, A cylindrical spout covering the valve case, A decorative cover is attached to the top of the spout and has an opening that allows the valve lever to swing and rotate, A guide member having a contact portion that faces and can contact the side surface of the valve lever over the swing range of the valve lever, and that allows relative rotation within a predetermined angular range with respect to the valve fixing member, The feature is that it includes a waterproof plate attached to the guide member or the valve fixing member in a manner that closes the gap between the guide member and the inner edge of the opening.

[0012] (effect) In this invention, a waterproof plate is provided to seal the gap between the decorative cover and the guide member. The decorative cover is a component that is exposed below the faucet handle, and there is a possibility that water may seep into the interior of the decorative cover by running along its surface. However, by providing a waterproof plate in the gap between the decorative cover and the guide member located at the top of the decorative cover, the gap between the components around the valve lever is reduced, and the intrusion of water into the interior of the decorative cover can be significantly reduced.

[0013] Furthermore, although there is a gap between the guide member and the valve lever corresponding to the movement trajectory of the valve lever, this gap is located in the center of the cylindrical wall section of a typical faucet lever, and water rarely reaches this position.

[0014] With this configuration, water is less likely to enter the interior from below the faucet lever through the opening in the decorative cover, preventing contamination of the valve's moving parts and resulting in a faucet device that can maintain good working condition for a long period of time.

[0015] (Feature composition) In the faucet device according to the present invention, the waterproof plate may be oriented in the direction of mounting the decorative cover to the spout and may have an annular surface that is in close proximity to and facing the inner edge.

[0016] (effect) By providing the annular surface of this structure, the gap between the cosmetic cover and the waterproof plate can be kept small, and water can be effectively prevented from entering the inside of the cosmetic cover through the gap between the two.

[0017] Also, if the cosmetic cover is likely to be separated from the spout, the annular surface of the waterproof plate can abut against the cosmetic cover to prevent separation from the spout. That is, the waterproof plate can also function as a fixing member for the cosmetic cover, and the fixing structure of the cosmetic cover to the spout can be simplified.

[0018] (Characteristic configuration) In the faucet device according to the present invention, the waterproof plate can be configured to be attached to the guide member.

[0019] (Effect) If the waterproof plate is attached to the guide member as in this configuration, the waterproof plate rotates together with the valve lever. That is, the waterproof plate rotates together with the faucet lever attached to the valve lever. As a result, for example, the gap between the waterproof plate and the valve lever always has a constant positional relationship with respect to the extending direction of the faucet lever. Since water often travels along the surface of the faucet lever into the inside of the decorative plate, by making the shape of the waterproof plate correspond to the operating direction of the faucet lever as in this configuration, water intrusion from the gap between the waterproof plate and the valve lever is effectively prevented.

[0020] In addition, in this configuration, since the waterproof plate and the cosmetic cover rotate relative to each other, it is preferable that the annular surface of the waterproof plate is separated from the inner edge portion of the cosmetic cover or abuts under an extremely light contact pressure.

[0021] (Characteristic configuration) In the faucet device according to the present invention, it is convenient if the waterproof plate has a window portion shaped along the swing locus of the valve lever.

[0022] (Effect) The opening of the waterproof plate is preferably as small as possible. However, it is necessary to ensure the swing of the valve lever, and it is difficult to completely eliminate the opening from the waterproof plate. Therefore, in this configuration, the opening of the waterproof plate is a window portion having a shape along the swing locus of the valve lever, and when the valve lever swings, the side surface of the valve lever and the side surface of the waterproof plate are in close proximity to each other. With this configuration, the gap between the two side surfaces is minimized, and water intrusion from the gap is prevented.

[0023] (Characteristic configuration) In the faucet device according to the present invention, it is convenient if the waterproof plate has a snap-fit locking portion for the guide member.

[0024] (Effect) When the waterproof plate prevents the removal of the decorative cover, the spout that abuts against the decorative cover also has an anti-removal effect. If the anti-removal functions of both are exerted by one waterproof plate, simplification of these mounting structures can be expected. In that case, if the waterproof plate is snap-fitted to the guide member, the waterproof plate can be easily detached. Therefore, the assembly and disassembly of the faucet device are facilitated, and the maintenance and repair work of the faucet device are facilitated.

[0025] (Characteristic configuration) The assembly method of the faucet device according to the present invention is as follows. A valve having a valve lever for opening and closing and switching the water discharge passage is disposed inside a valve case installed in a spout. When fixing a valve fixing member for fixing the valve to the valve case, A contact portion that faces and can contact the side surface of the valve lever over the swing range of the valve lever is provided, and a guide member that allows relative rotation within a predetermined angle range with respect to the valve fixing member is fixed together with the valve fixing member. A decorative cover having an opening that allows the swinging and rotating operations of the valve lever is attached to the upper end of the spout. The present invention is characterized in that a waterproof plate shaped to seal the gap between the guide member and the inner edge of the opening is attached to the guide member or the valve fixing member.

[0026] (effect) With this method, a waterproof plate is attached to the opening at the top of the decorative cover, further reducing the size of the opening in the decorative cover and enhancing the waterproofing effect.

[0027] Furthermore, the waterproof plate allows the decorative cover to be held in place, simplifying the fixing structure and internal structure of the decorative cover. This increases the design flexibility of the components, making it possible to rationally configure the faucet device. [Brief explanation of the drawing]

[0028] [Figure 1] Cross-sectional perspective view showing the overall configuration of the faucet device according to the present invention. [Figure 2] Cross-sectional view showing the main components of the faucet device according to the present invention. [Figure 3] Exploded perspective view showing the main components of the faucet device according to the present invention. [Modes for carrying out the invention]

[0029] (overview) The faucet device S of the present invention prevents water from entering near the base of the faucet lever 9, thereby preventing contamination around the switching valve 4 and impairing the switching function of the valve 4. Furthermore, by improving the prevention structure, the structure from the valve case 3 to the faucet lever 9 is made more efficient, resulting in a faucet device S that is easy to assemble and disassemble. Hereinafter, embodiments of the faucet device S of the present invention will be described with reference to the drawings.

[0030] [First Embodiment] (Basic configuration) Figures 1 to 3 show a faucet device S according to an embodiment of the present invention. In this faucet device S, for example, a shank 1 is attached to a kitchen sink, a substantially cylindrical main body member 10 is connected to the upper part of the shank 1, and a valve case 3 and a valve 4 are connected to the main body member 10. The shank 1, the main body member 10, and the valve case 3 are enclosed in a spout 2, and a decorative cover 7 is attached to the upper part of the spout 2. A valve fixing member 5, a guide member 6, a waterproof plate 8, etc. are attached to the upper part of the valve 4 and inside the decorative cover 7. This prevents water from entering the inside of the decorative cover 7 and efficiently fixes the spout 2 and the decorative cover 7. The configuration of each part will be described below.

[0031] (Valves and valve cases) Valve 4 is equipped with a rotating plate having predetermined holes and a sliding plate that opens and closes each hole in order to open and switch the water discharge flow path. To supply flowing water to valve 4, valve 4 is enclosed in a roughly cylindrical valve case 3. Multiple flow paths are formed in the valve case 3 for the circulation of fluid obtained from cold water piping and hot water piping connected below the shank 1. Multiple flow paths 41 open below valve 4, and these openings are connected to corresponding flow paths that open at the bottom 31 of valve case 3.

[0032] A small-diameter protrusion 42 is formed at the top of the valve 4, and a valve lever 43 is provided inside the small-diameter protrusion 42. A faucet lever 9 is further connected to the valve lever 43. By swinging the faucet lever 9 up and down or rotating it horizontally, the valve lever 43 responds to this movement, and the opening and closing operation and switching operation of the switching channel formed inside the valve 4 are performed.

[0033] (Valve fixing member) The valve 4 housed in the valve case 3 is fixed by screwing a roughly cylindrical valve fixing member 5 into the valve case 3. For this purpose, a female thread 32 is formed on the inner surface of the upper opening of the valve case 3, and a male thread 51 is formed on the lower outer surface of the valve fixing member 5. In addition, the upper outer surface of the valve fixing member 5 is configured as a large-diameter hexagonal head 52 so that a wrench can be attached to it.

[0034] A groove 53 is formed around the entire circumference of the inner surface of the valve fixing member 5. The retaining claw 64 of the guide member 6, which will be described later, engages with this groove 53.

[0035] (Shank and main body components) As shown in Figure 1, a roughly cylindrical main body member 10 and a shank 1 are connected to the lower side of the valve case 3. Both the main body member 10 and the shank 1 are enclosed within the spout 2. The shank 1 is fixed by clamping the countertop of the kitchen sink with a flange on its upper part and a shank nut 1b screwed onto the threaded portion 1a at its lower part. The main body member 10 is fitted onto the cylindrical portion 1c that protrudes upward from the flange, and the two are fixed together with multiple main body fixing screws 13. Cold water pipes and oil water pipes connected to the valve case 3 are inserted from below the kitchen sink into the interior of the shank 1 and the main body member 10. The valve case 3 is connected to the main body member 10 with multiple threaded members 12, etc.

[0036] (Spout) A spout 2 is positioned on the outside of the valve case 3 and shank 1. The spout 2 is a vertically elongated cylindrical exterior design component that constitutes the exterior of the faucet device S. An arm portion 22, which houses the water discharge channel and water purification cartridge, etc., protrudes from one side of the outer surface of the spout 2.

[0037] A circular opening 21 is formed at the top of the spout 2, into which the decorative cover 7 is inserted. A cylindrical insertion projection 72 is formed around the entire lower circumference of the decorative cover 7, and the insertion projection 72 is simply pushed into the opening 21 of the spout 2 to temporarily fix it in place.

[0038] In addition, the spout 2 may be integrally formed with the valve case 3, rather than in this configuration. Integrating the two reduces the number of components in the faucet device, which is advantageous in terms of parts manufacturing costs and assembly man-hours.

[0039] (Cosmetic cover) The decorative cover 7 is an aesthetic component that covers the upper part of the spout 2, and for example, it has a shape that is a part cut out of a sphere. The decorative cover 7 prevents water and debris from entering from the top of the spout 2 and also abuts against the upper end of the spout 2 to prevent the spout 2 from coming out upward.

[0040] Furthermore, a seal ring 33 is positioned between the inner surface of the spout 2 and the outer surface of the valve case 3. This seal ring 33 stabilizes the relative position of the spout 2 with respect to the valve case 3, and also prevents water from entering further downwards even if water does enter the interior of the spout 2.

[0041] (Guide member) The guide member 6 is a substantially cylindrical member that is inserted inside the valve fixing member 5. The lower part of the guide member 6 is formed in a cylindrical shape so as to be inserted into the valve fixing member 5. This cylindrical lower part is sandwiched between the outer surface of the small-diameter protrusion 42 provided on the upper part of the valve 4 and the inner surface 54 of the valve fixing member 5. However, the guide member 6 rotates horizontally together with the valve lever 43 and the valve 4. Therefore, a small gap is formed between the guide member 6 and the inner surface 54 of the valve fixing member 5. With this configuration, the guide member 6 guides the upper part of the valve 4 to rotate without rattling relative to the inner surface 54 of the valve fixing member 5.

[0042] Of the guide member 6, a plate-shaped contact portion 68 is formed at the position opposite the valve lever 43, which is close to or in contact with the valve lever 43 and guides the swing of the valve lever 43. Therefore, a gap exists between the contact portion 68 and the valve lever 43 that corresponds to the movement trajectory of the valve lever 43. However, this gap is located in the center of the cylindrical wall portion of a normal faucet lever 9, and water rarely reaches this position.

[0043] As shown in Figure 2, a slit 62 is formed along the circumferential direction on the cylindrical lower part of the guide member 6, and an elastic portion 63 is formed in the area partitioned by the slit 62. Furthermore, an outward-facing retaining claw 64 is formed on this elastic portion 63. These elastic portion 63 and retaining claw 64 are formed at two locations along the circumferential direction, that is, at radially opposite positions. This retaining claw 64 engages with a groove 53 formed on the inner surface of the valve fixing member 5. As a result, the guide member 6 rotates while being prevented from coming out of the valve fixing member 5.

[0044] To position the guide member 6 as described above, the retaining claw 64 of the guide member 6 is engaged with the groove 53 of the valve fixing member 5 before screwing the valve fixing member 5 into the valve case 3. At this time, the retaining claw 64 comes into contact with the inner surface 54 of the valve fixing member 5, causing the elastic portion 63 to shrink in diameter and engage with the groove 53. This engagement causes the cylindrical lower part of the guide member 6 to conform to the inner surface of the valve fixing member 5, so that the valve fixing member 5 and the guide member 6 can be simultaneously fitted onto the small diameter protrusion 42 of the valve 4. At this time, the valve lever 43 is inserted in the desired position into the guide opening 66 formed in the top plate portion 65 of the guide member 6.

[0045] A pair of waterproof plate fixing claws 67 are formed next to the guide opening 66 on the top plate portion 65 of the guide member 6. As will be described later, these waterproof plate fixing claws 67 engage with the locking portion 81 of the waterproof plate 8 in a snap-fit ​​manner. With this configuration, the waterproof plate 8 can be easily attached and detached. Therefore, the assembly and disassembly of the faucet device S is made easier, and repair work on the faucet device S is made easier.

[0046] (waterproof board) The waterproof plate 8 seals the gap between the inner edge 71a of the opening 71 of the decorative cover 7 and the guide member 6, and is attached to either the guide member 6 or the valve fixing member 5. In this embodiment, it is attached to the guide member 6.

[0047] The decorative cover 7 is a component that is exposed below the faucet lever 9, and there is a possibility that water may seep into the interior of the decorative cover 7 by running along its surface. Therefore, as in this configuration, by providing a waterproof plate 8 between the decorative cover 7 and the guide member 6, which are located at the top of the decorative cover 7, the gap between the components around the valve lever 43 is reduced, and the intrusion of water into the interior of the decorative cover 7 can be significantly reduced.

[0048] The waterproof plate 8 is installed after the guide member 6 is installed and the decorative cover 7 is attached to the top of the spout 2. The waterproof plate fixing claws 67 of the guide member 6 are engaged with the locking portion 81 formed on the edge of the window portion 82 formed in the center of the waterproof plate 8. The waterproof plate 8 rotates together with the guide member 6. Therefore, the waterproof plate 8 rotates in sync with the valve lever 43 and the faucet lever 9 attached to the valve lever 43.

[0049] In this configuration, the gap between the waterproof plate 8 and the valve lever 43 always corresponds to the direction of extension of the faucet lever 9. Therefore, by appropriately setting the shape of the waterproof plate 8, water intrusion through the gap between the waterproof plate 8 and the valve lever 43 can be effectively prevented.

[0050] The portion of the waterproof plate 8 facing the decorative cover 7 is provided with an annular surface 83 that faces the direction in which the decorative cover 7 is attached to the spout 2 and is in close proximity to the inner edge 71a of the decorative cover 7.

[0051] In this configuration, since the waterproof plate 8 and the decorative cover 7 rotate relative to each other, it is preferable that the annular surface 83 of the waterproof plate 8 is separated from the inner edge 71a of the decorative cover 7, or that it is in contact with it under extremely light contact pressure.

[0052] By providing the annular surface 83, the gap between the decorative cover 7 and the waterproof plate 8 can be kept small, effectively preventing water from entering the interior of the decorative cover 7 through the gap between them.

[0053] Furthermore, a window portion 82 is formed in the center of the waterproof plate 8, shaped to follow the oscillation trajectory of the valve lever 43. This further reduces the gap between the waterproof plate 8 and the valve lever 43. In addition, a wall portion 84 of a predetermined height is erected around the window portion 82. The reduction in the size of the window portion 82 and the installation of the wall portion 84 further reduce water intrusion.

[0054] Furthermore, in this embodiment, the waterproof plate 8 is positioned close to, or slightly touching, the decorative cover 7, preventing the decorative cover 7 from separating from the spout 2. In other words, the waterproof plate 8 also functions as a fixing member for the decorative cover 7. With the decorative cover 7 fixed, the spout 2 located beneath it is also inevitably fixed.

[0055] The waterproof plate 8 is mounted almost at the very top of the faucet device S and is installed last in the assembly of the faucet device S. In other words, to disassemble the completed faucet device S, removing the waterproof plate 8 makes it easy to attach and detach the other components. Since the waterproof plate 8 serves both as a water-stopping function and a fixing function for the decorative cover 7, the overall number of parts in the faucet device S is also reduced. As a result, the configuration and arrangement of components that were conventionally provided in the internal space of the decorative cover 7 can be changed or simplified.

[0056] For example, conventionally, valve cases and the like were made of expensive metal materials such as copper alloys. In such cases, the strength of the metal material was often utilized, and even thin-walled valve cases were fixed using screws. However, with the increasing use of resin in faucet devices to reduce CO2 emissions, there is a growing demand for valve cases and the like to be made of resin materials. In this regard, with this configuration, where the waterproof plate 8 with fixing function is located at the very top of the decorative cover 7, there is more space inside the decorative cover 7. As a result, it becomes possible to install a valve case 3 with a certain degree of thickness using resin material, and significant cost reductions are expected.

[0057] As a result of having the above configuration, the faucet device S of this embodiment makes it difficult for water to enter the interior from below the faucet lever 9 through the inner edge 71a of the decorative cover 7, prevents contamination of the movable part of the valve 4, and makes it possible to obtain a faucet device S that can maintain a good operating condition for a long period of time.

[0058] (Assembly method) The assembly method for the faucet device S of this embodiment is described again below.

[0059] After connecting the valve case 3 and the shank 1, a valve 4 for opening, closing, and switching the water discharge flow path is placed inside the valve case 3. The valve 4 is pre-assembled with multiple rotating and sliding plates that can be operated by the valve lever 43.

[0060] Next, the male thread 51 of the cylindrical valve fixing member 5 is screwed into the female thread 32 of the valve case 3 to fix the valve 4. This screwing presses the back surface of the valve 4 against the bottom 31 of the valve case 3 via multiple seal rings 44, thereby creating a sealed connection between the opening of the flow path formed in the valve 4 and the opening of the flow path formed in the valve case 3.

[0061] When screwing in the valve fixing member 5, the retaining claw 64 formed on the lower part of the substantially cylindrical guide member 6 is engaged with the groove 53 formed on the inner surface 54 of the valve fixing member 5. With the valve fixing member 5 screwed into the valve case 3, the lower cylindrical part of the guide member 6 is held in place by being sandwiched between the valve fixing member 5 and the small diameter protrusion 42 of the valve 4. As the retaining claw 64 rotates circumferentially while engaged with the groove 53, both the guide member 6 and the valve 4 rotate relative to the valve fixing member 5 over a predetermined angle.

[0062] Next, insert the decorative cover 7 into the opening 21 at the upper end of the spout 2 and position it. The decorative cover 7 can be easily removed from the spout 2 by pulling it upwards.

[0063] The waterproof plate 8 is brought close to the inner edge 71a of the decorative cover 7 from above, and the locking portion 81 formed on the edge of the window portion 82 of the waterproof plate 8 is snap-fitted into the waterproof plate fixing claw 67 provided on the upper part of the guide member 6. Much of the gap between the guide member 6 and valve lever 43 and the inner edge 71a of the decorative cover 7 is closed. The annular surface 83 formed downwards around the periphery of the waterproof plate 8 is separated from the inner edge 71a of the decorative cover 7, or is in contact with the inner edge 71a under very light contact pressure.

[0064] With this method, the waterproof plate 8 is attached to the inner edge 71a at the top of the decorative cover 7, effectively reducing the gap with the inner edge 71a and enhancing the waterproofing effect. Furthermore, the waterproof plate 8 can hold down the decorative cover 7, allowing for simplification of the fixing structure and internal structure of the decorative cover 7. As a result, the design freedom of the components is increased, making it possible to rationally configure the faucet device S.

[0065] [Material] Shank 1 requires strength because it forms the mounting portion to the top plate, as well as a stopper to restrict the rotation of the spout. Furthermore, cost reduction is also necessary, so it is preferable to construct it from copper alloy or ABS (acrylonitrile butadiene styrene) resin.

[0066] Since the valve 4 and valve case 3 require a certain level of strength and also need to be cost-effective, materials such as POM (polyacetal resin) (with 10% glass fiber added) and PPS (polyphenylene sulfide) are used.

[0067] The valve fixing member 5 is preferably made of PPS or a copper alloy to ensure the required strength.

[0068] The spout 2, decorative cover 7, and faucet lever 9 are aesthetic components that require plating, and ABS resin is used to reduce costs. Other materials such as copper alloy or zinc can also be used.

[0069] The guide member 6 should ideally possess not only strength but also flexibility, sliding properties, and water resistance. Furthermore, low cost is desirable. Therefore, POM, ABS resin, or PP (polypropylene) can be used.

[0070] The waterproof plate 8 needs to have sliding properties with the faucet lever 9, and POM or ABS resin is suitable for this purpose to reduce costs.

[0071] The faucet lever 9 is an aesthetic component and requires plating for its appearance, as well as chemical resistance and strength. ABS resin is used to reduce costs. Zinc can also be used. [Industrial applicability]

[0072] The faucet device according to the present invention can be widely applied to faucet devices equipped with a faucet lever that performs oscillating and rotating action in a position above the spout. [Explanation of Symbols]
