Mode for Carrying Out the Invention

[0010] (1) Embodiment As shown in FIGS. 1 and 2, a faucet device according to an embodiment is a so-called single lever type faucet device used in a kitchen or a washroom, and includes a lever 1 operated by a user to adjust the water volume, a spout 4 that supports the lever 1 and through which a hose 6 is movably inserted, and a water discharge head 7 connected to the tip of the hose 6.

[0011] The lever 1 is configured to be able to adjust the mixing ratio of water and hot water, and is also configured to be able to adjust the water volume of the mixed water of water and hot water.

[0012] The spout 4 includes a support pipe 2 that stands vertically and a water discharge pipe 3 that branches obliquely upward from an intermediate portion of the support pipe 2. The lever 1 is supported at the upper end of the support pipe 2 so as to be operable. The water discharge pipe 3 is a circular pipe having a smaller diameter than the support pipe 2, and a cylindrical holder 5 is attached to the inside thereof (see FIG. 3 etc.). A part of the holder 5 protrudes outside the water discharge pipe 3, but all of the holder 5 may be located inside the water discharge pipe 3. The spout 4 is made of metal or resin, and the holder 5 is made of resin.

[0013] The hose 6 is a flexible metal hose, and its tip is fixed to the water discharge head 7. The hose 6 is inserted through the holder 5 and can be pulled out by a predetermined dimension from the holder 5 and the water discharge pipe 3 to which it is attached.

[0014] The water discharge head 7 has a circular pipe-shaped gripping portion 71 that is connected in communication with the hose 6 and a circular pipe-shaped water discharge port portion 72 that protrudes from the gripping portion 71. The gripping portion 71 has an outer shape of a circular pipe having the same diameter as the water discharge pipe 3. As shown in FIG. 1, when the hose 6 is not pulled out normally, the water discharge pipe 3 and the gripping portion 71 have an outer shape of a continuous circular pipe. In other words, normally, the water discharge pipe 3 and the gripping portion 71 are connected in series so as to extend straight obliquely upward from an intermediate portion of the support pipe 2.

[0015] The water discharge port 72 extends radially outward from the side circumferential surface of the gripping portion 71. In a side view, the gripping portion 71 and the water discharge port 72 are continuously L-shaped. The water supplied to the water discharge head 7 through the hose 6 is discharged to the outside through the water discharge port 72.

[0016] The basic configuration of the water discharge device of one embodiment has been described above. In the following, the characteristic configurations included in the water discharge device of one embodiment will be described in more detail.

[0017] (1.1) Water discharge pipe The water discharge pipe 3 has a drain hole 31 and an auxiliary drain hole 32 located on its lower surface. Both the drain hole 31 and the auxiliary drain hole 32 are through holes opened downward. The drain hole 31 is provided in the tip-side portion of the water discharge pipe 3, and the auxiliary drain hole 32 is provided in the base-side portion of the water discharge pipe 3. The auxiliary drain hole 32 is located on the base side of the water discharge pipe 3 with respect to the drain hole 31.

[0018] The drain hole 31 has a larger dimension than the auxiliary drain hole 32 in the axial direction of the water discharge pipe 3. The opening area of the drain hole 31 is larger than the opening area of the auxiliary drain hole 32.

[0019] The lower wall portion 34 constituting a part of the water discharge pipe 3 is formed longer in the axial direction of the water discharge pipe 3 than the upper wall portion 35 constituting another part of the water discharge pipe 3. The drain hole 31 and the auxiliary drain hole 32 are located at a distance from each other in the axial direction of the water discharge pipe 3 on the lower wall portion 34.

[0020] (1.2) Holder The holder 5 includes a semi-cylindrical first divided body 5a constituting the upper half of the holder 5 and a semi-cylindrical second divided body 5b constituting the lower half of the holder 5. The cylindrical holder 5 is formed by combining the first divided body 5a and the second divided body 5b. Both the first divided body 5a and the second divided body 5b are resin-molded products.

[0021] The upper first divided body 5a has a surface 51a that contacts the lower second divided body 5b, and further has a plurality of pins 52 protruding from the surface 51a (see FIGS. 5 and 6). The plurality of pins 52 are, for example, four pins 52. The four pins 52 are each columnar pins.

[0022] The lower second divided body 5b has a surface 51b that contacts the surface 51a of the upper first divided body 5a, and further has a plurality of recesses 53 recessed from the surface 51b. The plurality of recesses 53 are four recesses 53. By inserting the four pins 52 of the first divided body 5a into the four recesses 53 of the second divided body 5b one by one, the first divided body 5a and the second divided body 5b are combined at proper positions.

[0023] Among the four recesses 53, the two recesses 53 located on the tip side of the holder 5 are circular recesses, and the two recesses 53 located on the base end side of the holder 5 are elliptical recesses 53 that are long in the axial direction of the holder 5. Here, the tip side and the base end side of the holder 5 are based on the state when the holder 5 is attached to the water discharge pipe 3. The tip side of the holder 5 is the side away from the support pipe 2, and the base end side of the holder 5 is the side close to the support pipe 2. The axial direction of the holder 5 coincides with the axial direction of the water discharge pipe 3.

[0024] A groove 54a is formed on the outer peripheral surface of the first divided body 5a over the entire circumferential length. A groove 54b is also formed on the outer peripheral surface of the second divided body 5b over the entire circumferential length. In a state where the first divided body 5a and the second divided body 5b are combined, the groove 54a and the groove 54b are connected to form a groove 54. The groove 54 is an annular groove provided continuously over the entire circumference of the outer peripheral surface of the holder 5.

[0025] A ring-shaped seal member 8 is fitted into the groove 54. The seal member 8 is an O-ring that seals the space between the holder 5 and the water discharge pipe 3 in a watertight manner. The seal member 8 contacts the bottom surface of the groove 54 with pressure and also contacts the inner peripheral surface of the water discharge pipe 3 with pressure.

[0026] On the inner peripheral surface of the first divided body 5a, a plurality of ribs 551a, 552a, 553a are formed. The plurality of ribs 551a, 552a, 553a are three ribs 551a, 552a, 553a that are spaced apart from each other in the axial direction of the holder 5. Each of the ribs 551a, 552a, 553a is an arc-shaped rib formed over the entire circumferential length.

[0027] On the inner peripheral surface of the second divided body 5b, a plurality of ribs 551b, 552b, 553b are formed. The plurality of ribs 551b, 552b, 553b are three ribs 551b, 552b, 553b that are spaced apart from each other in the axial direction of the holder 5. Each of the ribs 551b, 552b, 553b is an arc-shaped rib formed over the entire circumferential length.

[0028] In a state where the first divided body 5a and the second divided body 5b are combined, the rib 551a and the rib 551b are connected to form an annular rib 551 for drainage, the rib 552a and the rib 552b are connected to form an annular rib 552 for drainage, and the rib 553a and the rib 553b are connected to form an annular rib 553 for drainage. Hereinafter, for the sake of distinction, the annular rib 551 is referred to as the first annular rib 551, the annular rib 552 is referred to as the second annular rib 552, and the annular rib 553 is referred to as the third annular rib 551.

[0029] It is preferable that the first, second, and third annular ribs 551, 552, 553 are each formed continuously over the entire circumference of the holder 5. However, in at least one of the first, second, and third annular ribs 551, 552, 553, it is also acceptable that one or more locations in the circumferential direction are divided.

[0030] The first annular rib 551 is located on the most distal end side of the holder 5 among the first, second, and third annular ribs 551, 552, 553. The third annular rib 553 is located on the most proximal end side of the holder 5 among the first, second, and third annular ribs 551, 552, 553, and the second annular rib 552 is located between the first and third annular ribs 551, 553.

[0031] The axial widths of the first, second, and third annular ribs 551, 552, and 553 of the holder 5 are different from each other. The width of the first annular rib 551 is the widest, and the width of the second annular rib 552 is the narrowest. The width of the third annular rib 553 is narrower than the width of the first annular rib 551 and wider than the width of the second annular rib 552.

[0032] The first, second, and third annular ribs 551, 552, and 553 are positioned parallel to each other, and each is positioned with a minimum clearance with respect to the hose 6. The first, second, and third annular ribs 551, 552, and 553 are configured to be in sliding contact with the hose 6 respectively when the hose 6 moves in the axial direction of the holder 5.

[0033] Among the lower second divided body 5b, an opening 56 is provided between the first annular rib 551 (rib 551b) and the second annular rib 552 (rib 552b) for causing water that has entered the holder 5 through the hose 6 to flow down toward the water drain hole 31 of the drain pipe 3. The opening 56 is an opening portion that penetrates in the radial direction of the holder 5. In the axial direction of the holder 5, the opening 56 is formed over the entire length between the first annular rib 551 and the second annular rib 552.

[0034] Furthermore, the second divided body 5b has a hook 57 for hooking on the water drain hole 31 of the drain pipe 3. The hook 57 extends from the edge 561 on the distal end side of the holder 5 in the opening 56 toward the proximal end side of the holder 5 so as to be positioned within the opening 56. The hook 57 has a support piece 571 that protrudes toward the proximal end side of the holder 5 and a locking piece 572 that extends radially outward of the holder 5 from the tip of the support piece 571. As shown in FIG. 7, when the opening 56 is viewed in its penetrating direction (in other words, the radial direction of the holder 5), the hook 57 is positioned at the central portion in the circumferential direction of the holder 5 in the opening 56 and at the portion on the distal end side of the holder 5 in the opening 56.

[0035] In the state where the holder 5 is attached to the drain pipe 3, the locking piece 572 locks to the drain hole 31. At this time, the locking piece 572 closes a part of the drain hole 31 on the tip side of the drain pipe 3, but the other part of the drain hole 31 is opened so that water can be drained.

[0036] Furthermore, the second divided body 5b has a water stop wall 58 including a second annular rib 552 and an auxiliary opening 59 provided between the water stop wall 58 and the third annular rib 553.

[0037] The water stop wall 58 is an annular wall portion located on the base end side of the holder 5 with respect to the opening 56, and a groove 54 is provided on the outer peripheral surface of the water stop wall 58. A second annular rib 552 is provided at the end portion on the tip side of the holder 5 on the inner peripheral surface of the water stop wall 58. The second annular rib 552 protrudes inward in the radial direction. The inner peripheral surface of the water stop wall 58 excluding the second annular rib 552 is positioned with a certain clearance with respect to the hose 6 and is configured to keep non-contact with the hose 6 when the hose 6 moves in the axial direction of the holder 5.

[0038] In the state where the holder 5 is attached to the drain pipe 3, the end face 585 of the water stop wall 58 facing the tip side of the holder 5 is inclined so that the lower part is farther from the support pipe 2 and is inclined obliquely toward the drain hole 31. The end face 585 of the water stop wall 58 can function as a guide surface for guiding the water that has entered the holder 5 through the hose 6 to the drain hole 31 of the drain pipe 3. Also, the end face 585 of the water stop wall 58 can function as a guide surface for temporarily receiving the water that has flowed beyond the drain hole 31 and guiding it to the drain hole 31.

[0039] The auxiliary opening 59 is an opening portion through which the water that has passed through the hose 6 and exceeded the second annular rib 552 can flow toward the auxiliary drain hole 32 of the drain pipe 3. The auxiliary opening 59 penetrates in the radial direction of the holder 5.

[0040] In a state where the holder 5 is attached to the drain pipe 3, the first annular rib 551 is located on the distal end side of the drain pipe 3 with respect to the water drain hole 31, and the water stop wall 58 is located on the proximal end side of the drain pipe 3 with respect to the water drain hole 31. In other words, in the axial direction of the drain pipe 3, the first annular rib 551 is located closer to the distal end of the drain pipe 3 than the water drain hole 31, and the water stop wall 58 is located closer to the proximal end of the drain pipe 3 than the water drain hole 31. The second and third annular ribs 552, 553 are located on the proximal end side of the drain pipe 3 with respect to the water drain hole 31. In other words, in the axial direction of the drain pipe 3, the second and third annular ribs 552, 553 are located closer to the proximal end of the drain pipe 3 than the water drain hole 31.

[0041] Also, in a state where the holder 5 is attached to the drain pipe 3, the auxiliary water drain hole 32 is located on the proximal end side of the drain pipe 3 with respect to the auxiliary opening 59 and the third annular rib 553. In other words, in the axial direction of the drain pipe 3, the auxiliary water drain hole 32 is located closer to the proximal end of the drain pipe 3 than the auxiliary opening 59 and the third annular rib 553.

[0042] Therefore, in the faucet device of one embodiment, even if the water passing through the hose 6 penetrates into the holder 5 beyond the first annular rib 551, the water can be dropped downward through the opening 56 and guided to the water drain hole 31 of the drain pipe 3. In addition, even if a part of the water that has penetrated into the holder 5 beyond the first annular rib 551 flows along the hose 6 as it is, the inflow of the water can be blocked by the second annular rib 552 and guided to the water drain hole 31 by the end face 585 of the water stop wall 58. Even if the water passing through the hose 6 penetrates beyond the second annular rib 552, the inflow of the water can be blocked by the third annular rib 553 and guided to the auxiliary water drain hole 32 through the auxiliary opening 59.

[0043] Therefore, according to the faucet device of one embodiment, it is possible to effectively suppress the water passing through the hose 6 from penetrating into the proximal end side of the drain pipe 3 and thus into the support pipe 2.

[0044] (2) Modification As described above, the faucet device of the present disclosure has been described based on the embodiments shown in the accompanying drawings, but the faucet device of the present disclosure is not limited to the above embodiments.

[0045] For example, the number of the annular ribs 551, 552, 553 of the holder 5 is not limited to three, and may be two or four or more.
