Description

[Technical field]

[0001] The present disclosure relates to a hose guide or a water receiving tank. The present disclosure also relates to a water faucet device having a hose guide or a water receiving tank. [Background technology]

[0002] Some faucets that are attached to kitchens, washbasins, etc. have flexible hoses. The flexible hose allows the water spout head to be removed from the faucet body while pulling out the hose and then water can be spouted. The flexible hose has a length required for pulling out. When the water spout head is attached to the faucet body, the flexible hose hangs down from the bottom of the faucet.

[0003] When the flexible hose is pulled out, it may get caught on the water supply faucet, etc. Also, when cleaning the faucet, water may get into the faucet and drip down the sink. To prevent this, a water receiving tank is provided.

[0004] Usually, the water receiving tank is fixed by hanging it on two screws driven into the back wall of the kitchen. Japanese Utility Model Application Publication No. 64-28480 discloses an attachment structure for the water receiving tank of a hair washing vanity unit, in which the water receiving tank is attached to the wall on which the hair washing vanity unit is installed via a spacer that forms a gap for piping.

[0014] Hereinafter, the embodiments will be described in detail with reference to the drawings as appropriate.

[0015] FIG. 1 is a perspective view of a water faucet device 2 according to one embodiment, FIG. 2 is a front view of the water faucet device 2, and FIG.

[0016] The water faucet device 2 includes a water receiving tank 100 according to one embodiment. This water receiving tank 100 also functions as a hose guide 102. That is, the water faucet device 2 includes a hose guide 102 according to one embodiment.

[0017] 4 is a perspective view of the faucet 2a. The faucet 2a is the faucet device 2 excluding the water receiving tank 100 (hose guide 102).

[0018] As shown in Figures 1 to 4, the faucet 2a has a main body 4, a lever handle 6, and a water discharge head 8. The faucet 2a is a so-called single-lever faucet. The faucet 2a is a hot and cold water mixing faucet. The temperature of the water discharged can be adjusted by turning the lever handle 6 left and right. The amount of water discharged can be adjusted by turning the lever handle 6 up and down. The main body 4 has a built-in valve mechanism that allows the temperature and amount of water discharged to be adjusted. This valve mechanism is well known. The lever handle 6 is an example of a handle that can adjust the water discharge stop and the amount of water discharged.

[0019] Furthermore, the faucet 2a has a hot water introduction pipe 10, a water introduction pipe 12, a discharge pipe 14, and a flexible hose H1. The hot water introduction pipe 10 extends downward from the main body 4. The hot water introduction pipe 10 is connected to a hot water tap (not shown). The water introduction pipe 12 extends downward from the main body 4. The water introduction pipe 12 is connected to a water supply tap (not shown). The discharge pipe 14 extends downward from the main body 4. The discharge pipe 14 is connected to a flexible hose H1. The discharge pipe 14 is connected to the water discharge head 8 via the flexible hose H1. Heated hot water is introduced into the hot water introduction pipe 10. Unheated water (cold water) is introduced into the water introduction pipe 12. Hot water from the hot water introduction pipe 10 and water from the water introduction pipe 12 are introduced into the valve mechanism. The mixing ratio of hot water and water is adjusted by the valve mechanism. This mixing ratio achieves temperature adjustment of the discharged water. The mixture of hot water and cold water flows into the discharge pipe 14. In the following, heated hot water, unheated water (cold water), and the mixture of these may also be simply referred to as "water".

[0020] In addition, the pipe that supplies water to the faucet 2a is also referred to as a supply pipe in this application. In this application, the hot water introduction pipe 10 and the cold water introduction pipe 12 are the supply pipes 11. In this application, there are two supply pipes 11. The number of supply pipes 11 is not limited. For example, there may be only one supply pipe 11.

[0021] The water discharge head 8 has a water guide section 16, an operating section 18, a water shape adjustment section 20, and a discharge port 22. The hot and cold mixed water flowing out of the valve mechanism passes through the discharge pipe 14, the flexible hose H1, and the water guide section 16, and is discharged from the discharge port 22. The water shape adjustment section 20 can change the shape (water shape) of the discharged water. The water shape adjustment section 20 has a water shape adjustment lever 24. The water shape can be changed by operating the water shape adjustment lever 24. The operating section 18 is a push button. The operating section 18 may be, for example, a lever. By operating the operating section 18, the discharged water can be switched between raw water and purified water.

[0022] A water purification cartridge (not shown) is built into the water conducting portion 16. The faucet 2a (the water discharge head 8) including this water conducting portion 16 includes a faucet-integrated water purifier.

[0023] The water-spouting head 8 has a grip portion 26. A user can grasp the grip portion 26 and remove the water-spouting head 8 from the main body portion 4 while pulling out the flexible hose H1. In the water-spouting head 8, the water-guiding portion 16 is the grip portion 26.

[0024] 4, the flexible hose H1 has an outgoing path portion 30, a return path portion 32, and a folded-back portion 34. The folded-back portion 34 constitutes the lowermost portion of the flexible hose H1. The flexible hose H1 hangs down in a folded-back state at the folded-back portion 34. In the flexible hose H1, the outgoing path portion 30 is a portion upstream of the folded-back portion 34, and the return path portion 32 is a portion downstream of the folded-back portion 34.

[0025] Although the flexible hose H1 is generally a flexible metal hose made of metal, the material and specifications of the flexible hose H1 are not limited.

[0026] When the flexible hose H1 is pulled out, the position of the folded-back portion 34 in the flexible hose H1 changes. Depending on the length pulled out, the position of the folded-back portion 34 in the flexible hose H1 changes, and accordingly, the positions of the forward path portion 30 and the return path portion 32 in the flexible hose H1 also change. The forward path portion 30, the return path portion 32, and the folded-back portion 34 may be determined in a state (normal state) in which the flexible hose H1 is not pulled out. This normal state is a state in which the water spouting head 8 is attached to the main body portion 4, and is the state shown in Figures 1 to 4.

[0027] Furthermore, the faucet 2a has a shank tube 40, a washer 41, and a faucet fixing nut 42. The shank tube 40 is attached to the lower end of the main body 4. The shank tube 40 extends downward from the lower end of the main body 4. The shank tube 40 has a male thread portion 44 on its outer circumferential surface. The hot water inlet pipe 10, the cold water inlet pipe 12, and the discharge pipe 14 pass through the inside of the shank tube 40. In this application, a tubular threaded pipe having a male thread on its outer circumferential surface is referred to as a shank tube. The faucet fixing nut 42 is screwed into the male thread portion 44. The material of the shank tube 40 is usually resin or metal. In the case of metal, brass is preferable from the viewpoint of ensuring strength during construction and productivity.

[0028] The shank tube 40 serves to secure the faucet 2a to a mounting base. The mounting base is, for example, a kitchen countertop. The faucet 2a can be secured to the kitchen countertop by passing the shank tube 40 through a through hole provided in the countertop and sandwiching the countertop between the lower end surface of the main body 4 and the faucet fixing nut 42. The faucet does not have to have a shank tube. For example, a known top-mounted faucet does not have a shank tube.

[0029] The hot water introduction pipe 10 has a metal pipe section 10a and a flexible pipe section 10b. The metal pipe section 10a connects the water faucet 2a and the flexible pipe section 10b. The metal pipe section 10a is a pipe made of only metal. In this embodiment, the metal pipe section 10a is a copper pipe. The flexible pipe section 10b is a pipe with higher flexibility than the metal pipe section 10a. The bending rigidity of the flexible pipe section 10b is lower than that of the metal pipe section 10a. When a water receiving tank 100 (hose guide 102) described later is attached to the flexible pipe section 10b, the flexible pipe section 10b is bent by the weight of the water receiving tank 100 (hose guide 102). In this embodiment, the flexible pipe section 10b is a braided hose. A typical braided hose is a hose in which an inner tube is covered with a braid formed by weaving metal wires or strips. The material of the inner tube, which is the base material, can be resin (such as cross-linked polyethylene). Note that "FLEX" is an abbreviation of "flexible."

[0030] Furthermore, the hot water introduction pipe 10 has an intermediate connection part 10c and a faucet connection part 10d. The intermediate connection part 10c connects the metal pipe part 10a and the flexible pipe part 10b. The faucet connection part 10d connects the hot water introduction pipe 10 and a faucet (hot water supply faucet). The structure of the faucet connection part 10d is not limited. The material of the faucet connection part 10d is preferably metal, more preferably brass.

[0031] The structure of the hot water introduction pipe 10 is not limited. For example, the hot water introduction pipe 10 does not have to have the metal pipe portion 10a. In this case, the hot water introduction pipe 10 can be composed of a flexible pipe portion 10b and a water faucet connection portion 10d.

[0032] The water introduction pipe 12 has a metal pipe section 12a and a flexible pipe section 12b. The metal pipe section 12a connects the main body section 4 and the flexible pipe section 12b. The metal pipe section 12a is a pipe made of only metal. In this embodiment, the metal pipe section 12a is a copper pipe. The flexible pipe section 12b is a pipe having higher flexibility than the metal pipe section 12a. The bending rigidity of the flexible pipe section 12b is lower than that of the metal pipe section 12a. When a water receiving tank 100 (hose guide 102) described later is attached to the flexible pipe section 12b, the flexible pipe section 12b is bent by the weight of the water receiving tank 100 (hose guide 102). In this embodiment, the flexible pipe section 12b is a braided hose.

[0033] Furthermore, the water introduction pipe 12 has an intermediate connection part 12c and a faucet connection part 12d. The intermediate connection part 12c connects the metal pipe part 12a and the flexible pipe part 12b. The faucet connection part 12d connects the water introduction pipe 12 and a faucet (water supply faucet). The structure of the faucet connection part 12d is not limited. The material of the faucet connection part 12d is preferably metal, and more preferably brass.

[0034] As with the hot water introduction pipe 10, the structure of the water introduction pipe 12 is not limited. For example, the water introduction pipe 12 does not need to have the metal pipe portion 12a. In this case, the water introduction pipe 12 can be composed of a flexible pipe portion 12b and a water faucet connection portion 12d.

[0035] The discharge pipe 14 has a metal pipe section 14a and a flexible connection section 14b. The metal pipe section 14a is a pipe made of only metal. In this embodiment, the metal pipe section 14a is a copper pipe. The flexible connection section 14b connects the discharge pipe 14 to the flexible hose H1. The material of the flexible connection section 14b is metal (brass). The material of the flexible connection section 14b is not limited, and may be polyphenylene sulfide (PPS) or polyacetal (POM). The polyacetal (POM) may contain glass fiber. The structure of the discharge pipe 14 is not limited. The discharge pipe 14 does not have to have the metal pipe section 14a.

[0036] As shown in Figures 1 to 3, the water receiving tank 100 (hose guide 102) is attached to the faucet 2a. The water receiving tank 100 (hose guide 102) is attached to a predetermined portion of the faucet 2a. The predetermined portion is any portion of the faucet 2a. The water receiving tank 100 (hose guide 102) is attached only to a predetermined portion of the faucet 2a. The water receiving tank 100 (hose guide 102) is not attached to anything other than the faucet 2a. The water receiving tank 100 (hose guide 102) is not attached to a wall.

[0037] In this embodiment, the predetermined portion of the faucet 2a is the discharge pipe 14. More specifically, this predetermined portion is the metal pipe portion 14a. As described above, the metal pipe portion 14a is a copper pipe.

[0038] As described above, the water receiving tank 100 of this embodiment also functions as the hose guide 102. In the following, the water receiving tank 100 will first be described, and then the hose guide 102 will be described.

[0039] The water receiving tank 100 has a tank portion 104, a connecting portion 106 that connects to a predetermined portion of the faucet 2a, and an extension portion 108 that extends between the tank portion 104 and the connecting portion 106. The tank portion 104 forms a container that is open at the top. The tank portion 104 has a side wall portion s1, a bottom portion b1, and an upper opening k1. The side wall portion s1 forms a ring-shaped wall portion as a whole. The tank portion 104 has a water receiving function that can store water.

[0040] The tank portion 104 receives the hanging flexible hose H1. The tank portion 104 receives the outgoing path portion 30 and the returning path portion 32 together. In other words, the outgoing path portion 30 and the returning path portion 32 are received in one space formed inside the tank portion 104.

[0041] The hose guide 102 has the same structure as the water receiving tank 100. The tank portion 104 described above is the guide portion 110 in the hose guide 102. That is, the hose guide 102 has the guide portion 110, a connecting portion 106 that connects to a predetermined portion of the faucet 2a, and an extension portion 108 that extends between the guide portion 110 and the connecting portion 106. The guide portion 110 has a side wall portion s1, a bottom portion b1, and an upper opening k1. The side wall portion s1 forms a ring-shaped wall portion as a whole. The side wall portion s1 has a guide function for guiding the flexible hose H1. Furthermore, the guide portion 110 has a water receiving function that can store water. The presence of the bottom portion b1 adds a water receiving function to the guide portion 110. The bottom portion b1 also has a guide function.

[0042] The guide portion 110 receives the hanging flexible hose H1. The guide portion 110 receives the outgoing path portion 30 and the returning path portion 32 together. In other words, the outgoing path portion 30 and the returning path portion 32 are received in one space formed inside the guide portion 110.

[0043] In this embodiment, the water receiving tank 100 (hose guide 102) is made up of a plurality of (two) members. The water receiving tank 100 (hose guide 102) has an adapter member 112 and a main body member 114.

[0044] Fig. 5(a) is a perspective view of the adapter member 112, Fig. 5(b) is a side view of the adapter member 112, and Fig. 5(c) is a plan view of the adapter member 112 seen from above. Fig. 6(a) is a perspective view of the main body member 114, Fig. 6(b) is a side view of the main body member 114, and Fig. 6(c) is a plan view of the main body member 114 seen from above.

[0045] The adapter member 112 constitutes the coupling portion 106 and the extension portion 108. That is, as shown in Figures 5(a) to (c), the adapter member 112 has the above-mentioned coupling portion 106 and the extension portion 108. The adapter member 112 also has a connection portion 118. Furthermore, the adapter member 112 has a main body locking portion 120.

[0046] The main body member 114 constitutes the tank portion 104 (guide portion 110). As shown in Figs. 6(a) to (c), the main body member 114 has the side wall portion s1, the bottom portion b1, and the upper opening k1 described above. The main body member 114 also has a main body connecting portion 122. The main body connecting portion 122 is provided on each of two opposing wall surfaces of the side wall portion s1 (see Fig. 6(b)).

[0047] The main body connecting portion 122 of the main body member 114 is connected to the connecting portion 118 of the adapter member 112. As shown in Figs. 5(a) to (c), the connecting portion 118 has two projections 118a. The projections 118a have a shaft portion 118b and a head portion 118c formed at the tip of the shaft portion 118b. On the other hand, as shown in Fig. 6(a), the main body connecting portion 122 has two holes 122a. Each of the holes 122a has a first hole 122b having a size that does not allow the head portion 118c to pass through but allows the shaft portion 118b to pass through, and a second hole 122c provided below the first hole 122b and having a size that allows the head portion 118c to pass through. The hole 122a forms an elongated hole that connects the first hole 122b and the second hole 122c.

[0048] The projection 118a is inserted into the hole 122a, and the main body member 114 is hung on the adapter member 112, whereby the main body connection part 122 is attached to the connection part 118. After the projection 118a is inserted into the second hole 122c, it moves upward and is inserted into the first hole 122b. In this state, the head 118c cannot pass through the first hole 122b, so the projection 118a does not come out of the hole 122a. The state in which the projection 118a moves to the first hole 122b is easily maintained due to gravity acting on the main body member 114. The main body member 114 is not easily removed from the adapter member 112. The connection structure between the main body member 114 and the adapter member 112 is not limited.

[0049] The main body locking portion 120 forms an abutment portion that abuts against the upper side and inner side of the upper edge portion of the main body member 114. The main body locking portion 120 makes it difficult for the main body member 114 to move relative to the adapter member 112, thereby improving the stability of the posture of the main body member 114. In addition, the main body locking portion 120 restricts the main body member 114 from moving upward relative to the adapter member 112. Therefore, the protrusion 118a is unlikely to move into the second hole 122c, and the main body member 114 is unlikely to come off from the adapter member 112.

[0050] In this way, the main body member 114 can be easily attached to the adapter member 112. Moreover, the main body member 114 is unlikely to come off from the adapter member 112. The attitude and position of the main body member 114 can be effectively maintained by the adapter member 112. The main body member 114 may be integral with the adapter member 112. The water receiving tank 100 (hose guide 102) may be integrally molded as a whole.

[0051] The shape of the coupling part 106 corresponds to the shape of the part (a specified part of the faucet 2a) to which the coupling part 106 is attached. The coupling part 106 has a structure capable of holding the specified part. In this embodiment, the coupling part 106 is attached to the specified part of the faucet 2a by utilizing elastic deformation. As shown in FIG. 5(c), the coupling part 106 has a first extension part 106a and a second extension part 106b that face each other. The tip edge t1 of the first extension part 106a and the tip edge t2 of the second extension part 106b are spaced apart. The tip edge t1 and the tip edge t2 are parallel to each other. The inner surface f1 of the first extension part 106a forms a concave curved surface. The inner surface f2 of the second extension part 106b forms a concave curved surface. These concave curved surfaces are along a common imaginary cylindrical surface. The first extension part 106a and the second extension part 106b form a cylinder with a part of the circumference missing.

[0052] As shown in the embodiment of FIG. 1, in this embodiment, the predetermined portion of the faucet 2a is the metal pipe portion (copper pipe) 14a of the discharge pipe 14. The outer surface of the metal pipe portion 14a is a cylindrical surface. The diameter of this cylindrical surface is approximately equal to the diameter of the imaginary cylindrical surface. The metal pipe portion 14a is fitted between the first extension portion 106a and the second extension portion 106b. When the joint portion 106 is attached to the metal pipe portion 14a, the inner surface f1 of the first extension portion 106a and the inner surface f2 of the second extension portion 106b are along the outer surface of the metal pipe portion 14a. The metal pipe portion 14a is sandwiched between the first extension portion 106a and the second extension portion 106b. When the joint portion 106 is attached to the metal pipe portion 14a, the tip edge t1 and the tip edge t2 of the joint portion 106 are pressed against the metal pipe portion 14a. This pressing causes the connecting part 106 to elastically deform so that the tip edges t1 and t2 separate, allowing the metal pipe section 14a to pass between the tip edges t1 and t2, and then the connecting part 106 holds the metal pipe section 14a while deforming so that this elastic deformation returns to its original shape. The connecting part 106 holds the metal pipe section 14a with a force that causes the elastic deformation to return to its original shape (elastic recovery force). A specified portion of the faucet 2a (the metal pipe section 14a) is fitted into the connecting part 106. The connecting part 106 can be easily attached to the metal pipe section 14a.

[0053] The mounting structure of the coupling part 106 is not limited. Any mounting structure that corresponds to a predetermined portion of the faucet 2a may be adopted. In this embodiment, there is one coupling part 106. There may be multiple coupling parts 106.

[0054] The extension portion 108 extends between the joining portion 106 and the connecting portion 118. The extension portion 108 extends in the up-down direction. In this embodiment, there is one extension portion 108. There may be a plurality of extension portions 108. As shown in FIG. 5(b), the extension portion 108 has a straight portion 108a that extends along a straight line. The ratio of the path length of the straight portion 108a to the path length of the extension portion 108 may be 70% or more, further 75% or more, and further 80% or more. This ratio may be 100%. These path lengths may be the length of the center line CL1 of the extension portion 108. When the water receiving tank 100 (hose guide 102) is in use, the straight portion 108a is oriented substantially vertically. In the present application, this "substantially vertical direction" preferably means an angle of 15° or less with respect to the vertical direction, more preferably an angle of 10° or less with respect to the vertical direction, and even more preferably an angle of 5° or less with respect to the vertical direction.

[0055] The extension portion 108 has a thin and long shape. The thin and long extension portion 108 is easily deformed (bending deformation). The main body member 114 may be displaced by an external force caused by the movement of the flexible hose H1 or the collision of an external member. The extension portion 108 may be deformed (bending deformation) in response to the displacement of the main body member 114. By the extension portion 108 deforming in response to the displacement of the main body member 114, when the main body member 114 is displaced by some external force, the coupling portion 106 is less likely to come off from a predetermined portion. From this viewpoint, the vertical length L1 of the extension portion 108 may be 10 mm or more, further 50 mm or more, further 100 mm or more, further 150 mm or more, or further 180 mm or more. From the same viewpoint, the maximum cross-sectional width of the extension portion 108 may be 50 mm or less, further 30 mm or less, or further 10 mm or less. Considering the length of the flexible hose H1 that is folded back and hung down, the vertical length L1 of the extension part 108 can be 400 mm or less, further 300 mm or less, or further 250 mm or less. Considering the strength of the extension part 108, the maximum cross-sectional width of the extension part 108 can be 1 mm or more, further 2 mm or more, or further 3 mm or more.

[0056] The up-down direction may be the vertical direction of the water receiving tank 100 (hose guide 102) in use. The maximum cross-sectional width may be the maximum length of a line segment that crosses a cross section taken along a plane perpendicular to the center line CL1. For example, if the cross section is rectangular, the maximum cross-sectional width is the length of the diagonal of the rectangle. In this embodiment, the cross section of the extension portion 108 is circular, and the maximum cross-sectional width is the diameter of the circle. In this embodiment, the up-down length L1 of the extension portion 108 is 200 mm. In this embodiment, the maximum cross-sectional width (diameter) of the extension portion 108 is 4 mm.

[0078] The water faucet device 60 includes a water receiving tank 600. That is, the water faucet device 60 has the water receiving tank 600 and a faucet 2a. This water receiving tank 600 also serves as a hose guide 602. That is, the water faucet device 60 includes the hose guide 602 and the faucet 2a.

[0079] The water receiving tank 600 (hose guide 602) is attached to the faucet 2a. The water receiving tank 600 (hose guide 602) is attached to a predetermined portion of the faucet 2a. The water receiving tank 600 (hose guide 602) is attached only to a predetermined portion of the faucet 2a.

[0080] In this embodiment, the predetermined portion of the faucet 2a is the shank pipe 40. The water receiving tank 600 (hose guide 602) is attached to the shank pipe 40.

[0081] The water receiving tank 600 has a tank portion 604, a connecting portion 606 that connects to a predetermined portion of the faucet 2a, and an extension portion 608 that extends between the tank portion 604 and the connecting portion 606.

Furthermore, the guide portion 610 has a water receiving function that can store water. Due to the presence of the bottom portion b1, the guide portion 610 is given a water receiving function. The bottom portion b1 also has a guide function. The guide portion 610 receives the outward path portion 30 and the return path portion 32 of the flexible hose H1 together.

[0083] The above-described embodiments provide the following advantages.

[0084] The water receiving tank 100 (hose guide 102) is attached to the faucet 2a, not to a wall surrounding the faucet device 2. This makes installation easy. That is, it is easy to align the position of the tank portion 104 (guide portion 110) with the position of the hanging flexible hose H1. In addition, the installation of the water receiving tank 100 (hose guide 102) to the faucet 2a is also easy.

[0085] When the water receiving tank is attached to a wall, the wall is shifted from the position directly below the faucet 2a. In addition, depending on the positions of the water supply faucet and hot water supply faucet, etc., it may be restricted to install screws at a desired position on the wall. The area under the sink or washstand where the water receiving tank is installed is a narrow space, and drainage pipes, etc. are also present. In this location, it is not easy to take measurements and construction work is difficult to carry out. It is possible to align the tank by installing a spacer or the like between the wall and the tank part (guide part), but this requires the work of installing the spacer and the determination of the width of the spacer, and the installation of the spacer itself may be difficult due to spatial constraints. In this way, when the tank part is attached to a wall, alignment is not easy. In contrast, in this disclosure, the water receiving tank 100 (hose guide 102) is attached to the faucet 2a. Therefore, there is no need to drive screws into the wall behind the faucet 2a, and the installation work is easy. Furthermore, since the water receiving tank 100 (hose guide 102) is attached to the faucet 2a, rather than to a wall separate from the faucet 2a, it is easy to align the tank portion 104 (guide portion 110) with the flexible hose H1.

[0086] When driving screws into a wall, it is inevitable that the wall will be damaged by the screw holes. In contrast, with the faucet device 2 of the present disclosure, the water receiving tank 100 (hose guide 102) can be installed without damaging the wall.

[0087] The connecting portion 106 has a structure that allows it to be easily attached to a predetermined portion of the faucet 2a. The connecting portion 106 has a structure that allows it to fit into a predetermined portion of the faucet 2a by elastic deformation. The connecting portion 106 is configured so that when pressed against a predetermined portion of the faucet 2a, it elastically deforms and fits into the predetermined portion. The connecting portion 106 is connected to the predetermined portion simply by being pressed. Furthermore, the connecting portion 106 can be removed from the predetermined portion simply by being pulled. In this way, the water receiving tank 100 (hose guide 102) is easy to attach.

[0088] The water receiving tank 100 (hose guide 102) can be attached to any location on the faucet 2a. The connecting portion 106 can be structured so that it can be connected to a predetermined location on the faucet 2a. By selecting a predetermined location on the faucet 2a, the position of the tank portion 104 (guide portion 110) can be finely adjusted.

[0089] The location where the water receiving tank 100 (hose guide 102) is attached is not limited. In other words, the specified location of the faucet 2a is not limited. When the faucet 2a is attached to a mounting base such as a top plate, the main body 4 and the water discharge head 8 are located on the upper side (one side) of the mounting base, and the hanging flexible hose H1 is located on the lower side (other side) of the mounting base. In this case, it is preferable that the specified location of the faucet 2a is located on the lower side (other side) of the mounting base.

[0090] Examples of the predetermined portion include the supply pipe 11 (hot water inlet pipe 10, cold water inlet pipe 12), the discharge pipe 14, and the shank pipe 40. In the embodiment of Fig. 1, the predetermined portion is the discharge pipe 14. In the embodiments of Figs. 9 and 11, the predetermined portion is the shank pipe 40.

[0091] In each of the above embodiments, the predetermined portion of the faucet 2a is one location, but the predetermined portion may be two or more locations.

[0092] The specified portion of the hot water introduction pipe 10 is not limited. This specified portion may be the metal pipe portion 10a, the flexible pipe portion 10b, the intermediate connection portion 10c, or the faucet connection portion 10d. From the viewpoint of the stability of the position of the tank portion 104 (guide portion 110), it is preferable that the specified portion is a portion that is not deformed by the weight of the water receiving tank 100 (hose guide 102) when the water receiving tank 100 (hose guide 102) is attached to the specified portion. From this viewpoint, the specified portion of the hot water introduction pipe 10 is preferably the metal pipe portion 10a and the intermediate connection portion 10c. From the viewpoint of ease of connection by the connection portion 106, it is more preferable that the specified portion of the hot water introduction pipe 10 is the metal pipe portion 10a. The metal pipe portion 10a is preferably a copper pipe. If it is a copper pipe, the metal pipe portion 10a will not bend by the weight of the water receiving tank 100 (hose guide 102), but can be bent relatively easily with bare hands, etc. This makes it easy to adjust the position of the tank portion 104 (guide portion 110). From the viewpoint of the ability to follow the position of the flexible hose H1, the water receiving tank 100 (hose guide 102) may be attached to the faucet 2a in a state in which the tank portion 104 (guide portion 110) can easily move. In this case, the predetermined portion may be, for example, the flexible pipe portion 10b.

[0093] The predetermined portion of the water introduction pipe 12 is not limited. This predetermined portion may be the metal pipe portion 12a, the flexible pipe portion 12b, the intermediate connection portion 12c, or the faucet connection portion 12d. From the viewpoint of the stability of the position of the tank portion 104 (guide portion 110), it is preferable that the predetermined portion is a portion that is not deformed by the weight of the water receiving tank 100 (hose guide 102) when the water receiving tank 100 (hose guide 102) is attached to the predetermined portion. From this viewpoint, the predetermined portion of the water introduction pipe 12 is preferably the metal pipe portion 12a and the intermediate connection portion 12c. From the viewpoint of ease of connection by the connection portion 106, it is more preferable that the predetermined portion of the water introduction pipe 12 is the metal pipe portion 12a. The metal pipe portion 12a is preferably a copper pipe. If it is a copper pipe, the metal pipe portion 12a will not bend by the weight of the water receiving tank 100 (hose guide 102), but can be bent relatively easily with bare hands, etc. This makes it easy to adjust the position of the tank portion 104 (guide portion 110). From the viewpoint of the ability to follow the position of the flexible hose H1, the water receiving tank 100 (hose guide 102) may be attached to the faucet 2a in a state in which the tank portion 104 (guide portion 110) can easily move. In this case, the predetermined portion may be, for example, the flexible pipe portion 12b.

[0094] The predetermined portion of the discharge pipe 14 is not limited. This predetermined portion may be the metal pipe portion 14a or the flexible joint portion 14b. From the viewpoint of the stability of the position of the tank portion 104 (guide portion 110), it is preferable that the predetermined portion is a portion that is not deformed by the weight of the water receiving tank 100 (hose guide 102) when the water receiving tank 100 (hose guide 102) is attached to the predetermined portion. The metal pipe portion 14a and the flexible joint portion 14b satisfy this condition. From the viewpoint of the ease of connection by the joint portion 106, the predetermined portion of the discharge pipe 14 is more preferably the metal pipe portion 14a. The metal pipe portion 14a is preferably a copper pipe. If it is a copper pipe, the metal pipe portion 14a will not bend by the weight of the water receiving tank 100 (hose guide 102), but can be bent relatively easily with bare hands, etc. This makes it easy to adjust the position of the tank portion 104 (guide portion 110).

[0095] Copper tubes that can be used for the metal tube portion 10a, the metal tube portion 12a, and the metal tube portion 14a are not limited. When the copper tube has an appropriate rigidity, when the water receiving tank 100 (hose guide 102) is attached to the copper tube, the tank portion 104 (guide portion 110) can be easily aligned, and the position of the tank portion 104 (guide portion 110) is maintained. From the viewpoint of appropriate rigidity, the outer diameter of the copper tube is preferably 5 mm or more and 10 mm or less, and the wall thickness of the copper tube is preferably 1.2 mm or more and 2 mm or less. From the viewpoint of appropriate rigidity, the material of the copper tube is preferably a copper alloy containing 84 mass% or more of Cu, preferably a copper alloy containing 86 mass% or more of Cu, and more preferably a copper alloy containing 89 mass% or more of Cu. The material of the copper tube may be 100 mass% of Cu.

[0096] The hot water tap to which the hot water introduction pipe 10 is connected and the water supply tap to which the water introduction pipe 12 is connected are installed on the wall or floor around the faucet 2a. The hot water introduction pipe 10 and the water introduction pipe 12 are usually bent in order to connect to the hot water tap and the water supply tap. The hot water tap and the water supply tap may be located on the left and right sides of the position directly below the main body 4 of the faucet 2a. In this case, the hot water introduction pipe 10 and the water introduction pipe 12 are bent to the left and right, respectively, as shown in FIG. 1. Also, the hot water tap and the water supply tap may be located on the left or right side of the position directly below the main body 4 of the faucet 2a. In this case, both the hot water introduction pipe 10 and the water introduction pipe 12 are bent in the same direction. In any case, the hot water introduction pipe 10 is usually bent toward the hot water tap, and the water introduction pipe 12 is bent toward the water supply tap. In contrast, the discharge pipe 14 does not need to be bent. The discharge pipe 14 is oriented substantially vertically. The metal pipe portion 14a extends substantially vertically. A flexible hose H1 is connected to the discharge pipe 14. By connecting the connecting portion 106 to the discharge pipe 14 (metal pipe portion 14a), the tank portion 104 (guide portion 110) can be easily disposed directly below the main body portion 4. By configuring the predetermined portion as the discharge pipe 14 (metal pipe portion 14a), it becomes easy to align the tank portion 104 (guide portion 110).

[0097] It is preferable that the position of the flexible hose H1 and the position of the tank portion 104 (guide portion 110) are highly consistent. If this consistency is high, the sliding resistance generated between the flexible hose H1 and the tank portion 104 (guide portion 110) is reduced when the flexible hose H1 is pulled out. Referring to FIG. 2, when the flexible hose H1 is pulled out, the return path portion 32 moves upward (see the arrow in FIG. 2). If the positional deviation of the tank portion 104 (guide portion 110) relative to the flexible hose H1 is large, the contact pressure between the return path portion 32 and the tank portion 104 (guide portion 110) becomes large, and the sliding resistance when the flexible hose H1 is pulled out increases. If this sliding resistance increases, it becomes difficult to pull out the flexible hose H1, and the usability of the faucet 2a decreases. If the above consistency is high, the flexible hose H1 becomes easy to pull out, and the usability of the faucet 2a improves.

[0098] If the hot water tap and cold water tap are offset to the left or right of the position directly below the main body 4 of the faucet 2a, it may be impossible to secure space to position the tank portion 104 (guide portion 110) directly below the main body 4. In such cases, the position of the tank portion 104 (guide portion 110) can be adjusted by bending the discharge pipe 14 (metal pipe portion 14a). This adjustment makes it possible to position the tank portion 104 (guide portion 110) while minimizing deviation from the position of the flexible hose H1. As mentioned above, this adjustment is easy when the metal pipe portion 14a is a copper pipe.

[0099] The extension portion 108 has a shape retention property that allows it to maintain a certain shape. Even if the extension portion 108 is elastically deformed, it returns to its original shape when the external force is removed. The shape retention property of the extension portion 108 stabilizes the position of the tank portion 104 (guide portion 110). The extension portion 108 may be a continuous body that does not have shape retention property. Examples of such a continuous body include a string, a rope, and a band. In this case, there is an advantage that the tank portion 104 (guide portion 110) is easily displaced in accordance with the displacement of the flexible hose H1.

[0100] The joining structure of the joining portion 106 is not limited. Examples of the joining structure include fitting using elastic deformation (see the joining portion 106 in FIG. 1), clamping using a clamping structure for fixing the faucet 2a to the mounting base (see the joining portion 506 in FIG. 9), screwing, attachment using magnetic force, hanging, tying, and the like. The structure of the joining portion 106 can be a structure that is easy to join to a selected predetermined portion. Also, a joining structure may be provided on the predetermined portion of the faucet 2a, and the joining portion 106 may be joined to the predetermined portion by the structure on the predetermined portion side. There may be no joining structure between the joining portion 106 and the predetermined portion, and a different joining member may be used. For example, the joining portion 106 and the predetermined portion may be joined by a joining member such as a fastener such as a cable tie or a clamp such as a clip.

[0101] In the embodiment of FIG. 1, the tank portion 104 (guide portion 110) forms a bottomed container that is open at the top. Therefore, the tank portion 104 (guide portion 110) has a water receiving function. The tank portion 104 (guide portion 110) also houses the forward path portion 30, the return path portion 32, and the folded back portion 34. The tank portion 104 (guide portion 110) has a guide function that restricts the horizontal movement of the flexible hose H1, particularly when the flexible hose H1 is pulled out. This guide function prevents the flexible hose H1 from getting caught on or coming into contact with surrounding portions (hot water tap, water tap, etc.), making it easier to pull out the flexible hose H1.

[0102] 9, the guide portion 510 does not have a bottom and does not have a water receiving function, but does have a guide function. That is, the guide portion 510 houses the outgoing path portion 30 and the return path portion 32, and has a guide function to restrict the horizontal movement of the flexible hose H1, particularly when the flexible hose H1 is pulled out. This guide function makes it easier to pull out the flexible hose H1.

[0103] In the embodiment of FIG. 1, the tank portion 104 (guide portion 110) receives the outgoing path portion 30 and the return path portion 32 together. In other words, the outgoing path portion 30 and the return path portion 32 are received in one space formed inside the tank portion 104 (guide portion 110). In the case of a tank portion or guide portion that solely restrains the outgoing path portion 30, the sliding resistance is likely to increase when the flexible hose H1 is pulled out. The same is true in the case of a tank portion or guide portion that solely restrains the return path portion 32. In this embodiment, since the outgoing path portion 30 and the return path portion 32 are received together in one space in which the outgoing path portion 30 and the return path portion 32 are accommodated, the outgoing path portion 30 and the return path portion 32 are unlikely to be restrained, and the flexible hose H1 is easy to pull out. In addition, it is easy to insert the outgoing path portion 30 and the return path portion 32 of the flexible hose H1 into this space.

[0104] The tank portion 104 (guide portion 110) receives the outward path portion 30 and the return path portion 32 together, and houses the folded-back portion 34. This provides excellent water capture capability for the water traveling down the flexible hose H1. The tank portion 104 (guide portion 110) provides excellent water receiving capability.

[0105] 9, the guide portion 510 also receives the outgoing path portion 30 and the returning path portion 32 together. In other words, the outgoing path portion 30 and the returning path portion 32 are received in one space formed inside the guide portion 510. This prevents the flexible hose H1 from getting caught on a faucet or the like, making it easy to pull out the flexible hose H1. It is also easy to insert the flexible hose H1 into the guide portion 510.

[0106] In the embodiments of Figs. 7(a) to (c) and Fig. 8, the length of the extension parts 208, 308 can be adjusted. Therefore, the length of the extension parts can be adjusted according to the length of the flexible hose H1. The length adjustment mechanism is not limited. As in the above embodiment, a mechanism can be adopted in which the extension part is composed of two members and the length of the extension part is adjusted by changing the connection position between them. Also, for example, as this length adjustment mechanism, a double pipe structure including an inner pipe and an outer pipe that can move relative to each other and a restricting part that restricts the relative movement between them may be adopted.

[0107] Preferable materials for the extension part include resin and metal. The resin also includes fiber-reinforced resin. From the viewpoint of cost, resin is more preferable, and POM (polyacetal) and PP (polypropylene) are more preferable.

[0108] Preferred materials for the joint include resin and metal. The resin also includes fiber-reinforced resin. From the viewpoint of cost, resin is more preferred, and POM (polyacetal) and PP (polypropylene) are more preferred.
