Description

[Technical Field]

[0001] The disclosed embodiments relate to a water faucet device. [Background technology]

[0002] BACKGROUND ART Conventionally, a faucet device is known in which a spout can be pulled out from a wall panel of a bathroom vanity (see, for example, Patent Document 1). A flexible hose connected to the spout is housed in the wall panel. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-20194 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional technology, a guide member that is fixed to a wall panel and guides a flexible hose guides the flexible hose into the wall panel, where the flexible hose starts to curve inside the wall panel and is housed in the wall panel. Therefore, the wall panel requires a large space to house the curved portion of the flexible hose, and the thickness of the wall panel that houses the flexible hose increases.

[0005] One aspect of the embodiment aims to provide a faucet device that allows the spout to be pulled out from the faucet mounting portion, and that allows the thickness of the faucet mounting portion to be reduced. [Means for solving the problem]

[0006] A water faucet device according to one aspect of the present invention includes a spout that can be pulled out from a water faucet attachment part, a flexible hose that connects the spout to a water supply source, and a guide member that slidably guides the flexible hose inserted therein and is fixed to the water faucet attachment part. The guide member has a curved base end portion within which the flexible hose begins to curve.

[0007] As a result, the flexible hose begins to curve within the guide member in the direction of being accommodated in the faucet mounting portion, and is accommodated within the faucet mounting portion. Therefore, the faucet device can reduce the space required to accommodate the curved flexible hose in the faucet mounting portion. Specifically, the faucet device can reduce the thickness of the faucet mounting portion required to accommodate the curved flexible hose.

[0008] In addition, the curved base end is located downstream of the faucet mounting portion in the flow direction of water discharged from the spout.

[0009] As a result, the flexible hose inserted into the guide member begins to curve in the direction of being accommodated in the faucet mounting portion from the downstream side of the faucet mounting portion, which allows the faucet device to reduce the space required to accommodate the curved flexible hose in the faucet mounting portion and allows the faucet mounting portion to be made thinner.

[0010] The guide member also has an insertion path formed therein for inserting the flexible hose, the cross-sectional area of ​​the insertion path being upstream of the curved base end being larger than the cross-sectional area of ​​the insertion path being downstream of the curved base end.

[0011] This allows the water faucet device to bend the flexible hose in the insertion passage upstream of the curved base end and accommodate the flexible hose in the water faucet attachment part. Also, when inserting the flexible hose from the water faucet attachment part into the guide member, the worker can easily insert the flexible hose into the insertion passage upstream of the curved base end.

[0012] In addition, the insertion path upstream of the curved base end is formed so as to widen in the direction in which the flexible hose is housed in the faucet attachment portion.

[0013] This allows the flexible hose to be inserted into the faucet attachment part along the insertion path upstream of the curved base end. The faucet device reduces the sliding resistance on the flexible hose when the spout is pulled out of the faucet attachment part and when the spout is pushed back toward the faucet attachment part. In other words, the faucet device allows the flexible hose to move smoothly.

[0014] Furthermore, the insertion path upstream of the curved base end has a curved surface that follows the curve of the flexible hose.

[0015] This allows the faucet device to slide the flexible hose along the curved surface. Therefore, the faucet device can reduce the sliding resistance on the flexible hose when the spout is pulled out from the faucet attachment part and when the spout is pushed back toward the faucet attachment part. In other words, the faucet device allows the flexible hose to move smoothly along the curved surface.

[0016] The faucet device also includes a hose guide that guides the sliding of the flexible hose housed in the faucet mounting portion.

[0017] This prevents the flexible hose from coming into contact with components other than the hose guide when the flexible hose accommodated in the faucet mounting portion moves within the faucet mounting portion. This reduces the sliding resistance of the flexible hose, allowing the faucet device to move the flexible hose smoothly.

[0018] The hose guide is also configured to cover the flexible hose.

[0019] This allows the faucet device to use the hose guide to guide the flexible hose housed in the faucet mounting portion around the entire circumference. Therefore, when the flexible hose housed in the faucet mounting portion moves within the faucet mounting portion, the faucet device can prevent the flexible hose from coming into contact with components other than the hose guide. Therefore, when the flexible hose housed in the faucet mounting portion moves within the faucet mounting portion, the faucet device can reduce the sliding resistance exerted on the flexible hose. In other words, the faucet device allows the flexible hose to move smoothly.

[0020] The guide member also has a rib capable of guiding the flexible hose in the insertion path upstream of the curved base end portion.

[0021] This allows the faucet device to reduce the sliding resistance on the flexible hose in the insertion path upstream of the curved base end. When the spout is pushed back after being pulled out of the faucet mounting portion, the faucet device can prevent the flexible hose from bending in a direction different from the direction in which the flexible hose is accommodated in the faucet mounting portion. Therefore, the faucet device can easily accommodate the flexible hose in the faucet mounting portion. Furthermore, the faucet device can improve the strength of the guide member by providing ribs on the guide member. [Effects of the Invention]

[0022] According to one aspect of the embodiment, in a faucet device in which the spout can be pulled out from the faucet mounting portion, the thickness of the faucet mounting portion can be reduced. [Brief explanation of the drawings]

In addition, the vertical direction will be referred to as the bottom side, and the direction opposite to the vertical direction will be referred to as the top side.

[0026] The bathroom vanity 1 includes a lower cabinet 2, a washbasin 3, a wall panel 4 (a faucet mounting portion), an operating device 5, and a faucet device 6.

[0027] The lower cabinet 2 is placed on the floor so that its back surface abuts against the wall on which the bathroom vanity 1 is installed, and is configured so that items can be stored inside.

[0028] The washbasin 3 is placed on the top surface of the lower cabinet 2, and is configured so that most of the depth of the bathroom vanity 1 can be used as a space for washing.

[0029] The wall panel 4 is provided to extend upward from the lower cabinet 2. The wall panel 4 is provided behind the washbasin 3. The wall panel 4 is configured as a box-shaped box that protrudes forward from the wall on which the bathroom vanity 1 is installed. The wall panel 4 houses various functional parts such as a flexible hose 10 (see Figure 2) described below. The wall panel 4 is configured to communicate with the lower cabinet 2. Some of the various functional parts such as the flexible hose 10 are housed in the lower cabinet 2. The wall panel 4 does not have to communicate with the lower cabinet 2. The various functional parts such as the flexible hose 10 may be housed only in the wall panel 4.

[0030] The operating device 5 is attached to the wall panel 4. The operating device 5 accepts operations related to the discharge of water from the faucet device 6. When operated by a user, the operating device 5 switches between a discharge state in which water is discharged from the faucet device 6 and a stopped state in which water is not discharged from the faucet device 6. When operated by a user, the operating device 5 adjusts the amount of water discharged from the faucet device 6. When operated by a user, the operating device 5 adjusts the temperature of the discharged water.

[0031] The water includes water supplied from an external water supply or the like, hot water supplied from a water heater, and hot water obtained by mixing water supplied from an external water supply or the like with hot water supplied from a water heater. For example, when adjusting the water temperature, the operating device 5 changes the mixing ratio of water supplied from an external water supply or the like and hot water supplied from the water heater. The operating device 5 does not have to adjust the water temperature.

[0032] The faucet device 6 is configured to discharge water in response to operation of the operating device 5. As shown in Figure 2, the faucet device 6 includes a flexible hose 10, a hose guide 11, and a spout 12. Figure 2 is a front view of a portion of the bathroom vanity 1. As shown in Figure 3, the faucet device 6 includes a guide member 13. Figure 3 is an enlarged view of the III-III cross section of Figure 2. The faucet device 6 is a pull-out type faucet device configured so that the spout 12 can be pulled out to wash hair or clean the washbasin 3.

[0033] In the following, the water flow direction may be defined as the direction of water discharged from the spout 12. In other words, the water flow direction is the direction of water flowing through the faucet device 6. The operating device 5 side of the water flow direction is upstream, and the spout 12 side is downstream. In addition, the pull-out direction of the spout 12 in the bathroom vanity unit 1 according to the embodiment is forward. In other words, the direction in which the spout 12 is pulled out and pushed back is the front-to-rear direction. The spout 12 may also be pulled out diagonally downward.

[0034] The flexible hose 10 is a flexible water supply hose that is coated with metal. The flexible hose 10 connects the spout 12 and a water supply pipe 14 (water supply source). The water supply pipe 14 is a pipe into which water flows when water is supplied by operating the operating device 5. The water supply pipe 14 is fixed to the lower cabinet 2, for example. One end of the flexible hose 10 is connected to the water supply pipe 14. The other end of the flexible hose 10 is connected to the spout 12.

[0035] The flexible hose 10 is housed in the wall panel 4 and the lower cabinet 2. As shown in FIG. 2, the flexible hose 10 extends downward from the water supply pipe 14 and is folded back upward at its lower end in a generally U-shape. After being folded back upward, the flexible hose 10 extends upward and is inserted into the wall panel 4, and is provided so as to extend upward within the wall panel 4. As shown in FIG. 3, the flexible hose 10 is provided so as to curve forward in the wall panel 4, pass through a guide member 13, and extend forward. The flexible hose 10 is connected to a spout 12 on the front side.

[0036] The flexible hose 10 is pulled out from the wall panel 4 and pushed back into the wall panel 4 in response to the operation of the spout 12 by the user.

[0037] The hose guide 11 is housed in the wall panel 4 and the lower cabinet 2. The hose guide 11 may be housed only in the wall panel 4. The hose guide 11 guides the flexible hose 10. Specifically, the hose guide 11 guides the sliding of the flexible hose 10 housed in the wall panel 4 and the lower cabinet 2. The hose guide 11 is provided in the wall panel 4 so as to guide the sliding of the flexible hose 10 extending downward from near the point where the flexible hose 10 bends forward.

[0038] The hose guide 11 is configured to cover the flexible hose 10. The hose guide 11 may be provided on the wall panel 4 and on a portion between the lower cabinet 2 and the flexible hose 10. For example, the hose guide 11 may be provided between the front wall panel 4 and the flexible hose 10. Alternatively, the hose guide 11 may be provided between the rear wall panel 4 and the flexible hose 10. The hose guide 11 is attached to the wall panel 4 via an attachment member.

[0039] The guide member 13 slidably guides the flexible hose 10 inserted inside. The guide member 13 is fixed to the wall panel 4. Specifically, as shown in FIG. 3 , the guide member 13 is attached to the wall panel 4 via an attachment member 15. The guide member 13 is attached to the wall panel 4 so as to pass through a hole 4a formed in the wall panel 4. When the spout 12 is not pulled out from the wall panel 4, the spout 12 is attached to the guide member 13. In other words, the spout 12 is detachable from the guide member 13.

[0040] The guide member 13 will be described with reference to Figures 3 and 4. As shown in Figure 4, the guide member 13 includes a guide main body 20, an attachment portion 21, and a support portion 22. Figure 4 is a perspective view of the guide member 13 as seen obliquely from behind.

[0041] The guide body 20 is formed in a cylindrical shape. The guide body 20 is provided so as to protrude forward from the wall panel 4. A portion of the guide body 20 is inserted into the hole 4a in the wall panel 4. The guide body 20 is provided so as to extend in the front-to-rear direction. The guide body 20 is provided with an insertion path 24 into which the flexible hose 10 is inserted. The guide body 20 includes a spout support portion 25 and an enlarged portion 26.

[0042] Spout support portion 25 is configured to allow spout 12 to be attached and detached. Spout support portion 25 is provided forward of wall panel 4. Spout support portion 25 is formed to extend along the front-rear direction.

[0043] The expansion portion 26 is provided rearward of the spout support portion 25. The expansion portion 26 is provided so as to extend rearward from the rear end of the spout support portion 25. The front end of the expansion portion 26 is provided forward of the wall panel 4. The rear end of the expansion portion 26 is provided so as to protrude into the wall panel 4.

[0044] The expanded portion 26 is formed to protrude outward beyond the spout support portion 25. The expanded portion 26 is formed to expand in the accommodation direction of the flexible hose 10, which is the direction in which the flexible hose 10 is accommodated in the wall panel 4. When the flexible hose 10 is accommodated downward from the guide member 13 into the wall panel 4, the accommodation direction of the flexible hose 10 is downward. Therefore, the expanded portion 26 is formed to expand downward. Specifically, the expanded portion 26 is formed to expand downward as it approaches the rear side.

[0045] The insertion path 24 includes a first insertion path 24a and a second insertion path 24b. The first insertion path 24a is formed so as to linearly support the flexible hose 10 inserted therein. The first insertion path 24a is formed along the front-rear direction. That is, the first insertion path 24a is formed so that the flexible hose 10 extends in the front-rear direction. The first insertion path 24a is formed in the spout support portion 25, for example.

[0046] The second insertion path 24b is provided rearward of the first insertion path 24a. The cross-sectional area of ​​the second insertion path 24b is larger than the cross-sectional area of ​​the first insertion path 24a. The cross-sectional area is the cross-sectional area on a plane perpendicular to the front-rear direction. The cross-sectional area of ​​the second insertion path 24b is the cross-sectional area on an imaginary line connecting the tips of ribs 27, which will be described later. The cross-sectional area of ​​the second insertion path 24b is the area into which the flexible hose 10 can be inserted in the second insertion path 24b.

[0047] The second insertion path 24b is formed so that the flexible hose 10 inserted into the second insertion path 24b curves in the direction in which the flexible hose 10 is housed in the wall panel 4. The second insertion path 24b is formed so as to widen in the direction in which the flexible hose 10 is housed in the wall panel 4. Specifically, the second insertion path 24b is formed so as to widen downward. For example, the second insertion path 24b has a curved surface 24c that follows the curve of the flexible hose 10. The curved surface 24c is formed so as to widen downward as it extends rearward. In other words, the curved surface 24c curves downward as it extends rearward.

[0048] In this way, the insertion path 24 has a curved base end 24d formed therein, where the flexible hose 10 starts to bend within the insertion path 24. That is, the guide member 13 has therein the curved base end 24d, where the flexible hose 10 starts to bend. The curved base end 24d is the location where the flexible hose 10 inserted into the first insertion path 24a starts to bend downward, which is the direction in which the flexible hose 10 is accommodated. For example, the curved base end 24d is the location that is the boundary between the first insertion path 24a and the second insertion path 24b in the front-rear direction.

[0049] The first insertion path 24a is an insertion path located downstream of the curved base end 24d in the direction of water flow, and the second insertion path 24b is an insertion path located upstream of the curved base end 24d in the direction of water flow.

[0050] A plurality of ribs 27 are formed in the second insertion path 24b. The plurality of ribs 27 are formed in the second insertion path 24b in a direction different from the direction in which the flexible hose 10 is accommodated. The plurality of ribs 27 are formed, for example, on the upper wall surface of the second insertion path 24b and on the side wall surfaces in the left and right directions of the second insertion path 24b.

[0051] The multiple ribs 27 are formed to extend in the front-to-rear direction. The multiple ribs 27 are configured to be able to guide the flexible hose 10. The multiple ribs 27 are formed to prevent the flexible hose 10 from bending in a direction different from the direction of accommodation when the flexible hose 10, which has been pulled out from the wall panel 4, is pushed back (stored) into the wall panel 4. The multiple ribs 27 are also formed to reduce contact resistance with the flexible hose 10 that comes into contact with the flexible hose 10 when the flexible hose 10 is pulled out from the wall panel 4 or when the flexible hose 10 is pushed back into the wall panel 4. The ribs 27 may also be formed on the curved surface 24c.

[0052] The mounting portion 21 is formed, for example, so as to protrude upward from the guide main body 20. The mounting portion 21 is formed with a screw hole 21a into which a screw 28 is inserted for fixing the guide member 13 to the mounting member 15. The support portion 22 is formed, for example, so as to protrude in the left-right direction from the guide main body 20. The support portion 22 is formed with an insertion hole 22a into which a support pin for supporting the guide member 13 is inserted.

[0053] Next, spout 12 will be described with reference to Figures 3, 5, and 6. Figure 5 is an enlarged view of the front end side of spout 12 shown in Figure 3. Figure 6 is a view of the front end side of spout 12 as seen from below.

[0054] The spout 12 is detachable from the guide member 13. The spout 12 is attached to the wall panel 4 via the guide member 13. That is, the spout 12 can be pulled out from the wall panel 4.

[0072] The flexible hose 10 is connected to the connection member 31, and when the spout 12 is pulled out from the wall panel 4, the flexible hose 10 moves integrally with the connection member 31 and is pulled out from the wall panel 4. In other words, the flexible hose 10 is pulled out from the wall panel 4 integrally with the spout 12.

[0073] When the spout 12 pulled out from the wall panel 4 is attached to the wall panel 4, that is, when the spout 12 is pushed back, the spout 12 and the flexible hose 10 are pushed back together.

[0074] When the spout 12 is pushed back, the stopper 35 abuts against the tip of the water discharge member 34 on the downstream side in the water flow direction, so the water discharge member 34 moves and is pushed back together with the exterior member 30. The water discharge member 34, joint member 33, and connection member 31 also move and are pushed back together. The flexible hose 10 is pushed back together with the connection member 31, and a portion of the flexible hose 10 is housed in the wall panel 4. Note that the engaging member 32 is in contact with the connection member 31 in the front-to-rear direction by the second engaging portion 41, and is engaged with the exterior member 30 by the first engaging portion 40, so it moves and is pushed back together with the exterior member 30 and the like.

[0075] The flexible hose 10 is inserted into the guide member 13, curves downward rearward from the curved base end 24d of the guide member 13, and is housed in the wall panel 4. The curved base end 24d is formed in the insertion path 24 of the guide member 13 and is formed forward of the wall panel 4. The guide member 13 has a curved surface 24c in a second insertion path 24b provided rearward of the curved base end 24d that widens downward toward the rear.

[0076] As a result, the flexible hose 10 curves downward along the curved surface 24c from the front side of the wall panel 4. This reduces the length of the curved flexible hose 10 in the front-to-rear direction within the wall panel 4. In other words, the length of the wall panel 4 in the front-to-rear direction required to accommodate the curved flexible hose 10 is reduced.

[0077] When the flexible hose 10 is pulled out from the wall panel 4, and when the flexible hose 10 is pushed back into the wall panel 4, the flexible hose 10 slides while being guided by the hose guide 11 within the wall panel 4. Therefore, the flexible hose 10 is prevented from coming into contact with, for example, other components, and moves smoothly along the hose guide 11 within the wall panel 4.

[0078] Furthermore, by forming a plurality of ribs 27 extending in the front-rear direction in the second insertion path 24b of the guide member 13, for example, when the flexible hose 10 is pushed back, the flexible hose 10 is guided by the ribs 27. Specifically, the ribs 27 prevent the flexible hose 10 from bending in a direction different from the direction in which it is stored in the wall panel 4.

[0079] The faucet device 6 includes a spout 12 that can be pulled out from the wall panel 4, a flexible hose 10 that connects the spout 12 to a water supply pipe 14, and a guide member 13 that slidably guides the flexible hose 10 inserted inside and is fixed to the wall panel 4. The guide member 13 includes a curved base end 24d inside where the flexible hose 10 begins to curve.

[0080] As a result, the flexible hose 10 begins to curve in the direction of accommodation of the flexible hose 10 within the guide member 13, and is accommodated in the wall panel 4. Therefore, the faucet device 6 can reduce the space required in the front-to-rear direction in the wall panel 4 to accommodate the curved flexible hose 10. Specifically, the faucet device 6 can reduce the thickness of the wall panel 4 required to accommodate the curved flexible hose 10. By reducing the thickness of the wall panel 4, the faucet device 6 can improve the design.

[0081] The curved base end portion 24d is located downstream of the wall panel 4 in the flow direction of water discharged from the spout 12.

[0082] As a result, the flexible hose 10 inserted into the guide member 13 starts to curve in the direction of accommodation of the flexible hose 10 from downstream of the wall panel 4. Therefore, the faucet device 6 can reduce the space required in the front-to-rear direction in the wall panel 4 to accommodate the curved flexible hose 10, allowing the thickness of the wall panel 4 to be reduced.

[0083] Further, an insertion path 24 into which the flexible hose 10 is inserted is formed in the guide member 13. The cross-sectional area of ​​the second insertion path 24b upstream of the curved base end 24d is larger than the cross-sectional area of ​​the first insertion path 24a downstream of the curved base end 24d.

[0084] This allows the water faucet device 6 to bend the flexible hose 10 in the second insertion passage 24b upstream of the curved base end 24d, and store the flexible hose 10 in the wall panel 4. Furthermore, when inserting the flexible hose 10 from the wall panel 4 into the guide member 13, the worker can easily insert the flexible hose 10 into the second insertion passage 24b upstream of the curved base end 24d.

[0085] Further, the second insertion path 24b located upstream of the curved base end portion 24d is formed so as to widen in the direction in which the flexible hose 10 is housed.

[0086] This allows the faucet device 6 to insert the flexible hose 10 into the wall panel 4 along the second insertion path 24b upstream of the curved base end 24d. The faucet device 6 can reduce the sliding resistance applied to the flexible hose 10 when the spout 12 is pulled out of the wall panel 4 and when the spout 12 is pushed back toward the wall panel 4. In other words, the faucet device 6 can move the flexible hose 10 smoothly.

[0087] Further, the second insertion path 24b on the upstream side of the curved base end portion 24d has a curved surface 24c that follows the curve of the flexible hose 10.

[0088] This allows the faucet device 6 to slide the flexible hose 10 along the curved surface 24c. Therefore, the faucet device 6 can reduce the sliding resistance applied to the flexible hose 10 when the spout 12 is pulled out from the wall panel 4 and when the spout 12 is pushed back toward the wall panel 4. In other words, the faucet device 6 allows the flexible hose 10 to move smoothly along the curved surface 24c.

[0089] The water faucet device 6 also includes a hose guide 11 that guides the sliding of a flexible hose 10 housed in the wall panel 4.

[0090] As a result, the faucet device 6 can prevent the flexible hose 10 housed in the wall panel 4 from coming into contact with components other than the hose guide 11 when the flexible hose 10 moves within the wall panel 4. As a result, the faucet device 6 can reduce the sliding resistance applied to the flexible hose 10. In other words, the faucet device 6 can move the flexible hose 10 smoothly.

[0091] The hose guide 11 is configured to cover the flexible hose 10 .

[0092] As a result, the faucet device 6 can use the hose guide 11 to guide the entire circumference of the flexible hose 10 housed in the wall panel 4. Therefore, when the flexible hose 10 housed in the wall panel 4 moves within the wall panel 4, the faucet device 6 can prevent the flexible hose 10 from coming into contact with components other than the hose guide 11. Therefore, when the flexible hose 10 housed in the wall panel 4 moves within the wall panel 4, the faucet device 6 can reduce the sliding resistance applied to the flexible hose 10. In other words, the faucet device 6 can move the flexible hose 10 smoothly.

[0093] The guide member 13 also includes a rib 27 capable of guiding the flexible hose 10 in the second insertion path 24b upstream of the curved base end portion 24d.

[0094] As a result, the faucet device 6 can reduce the sliding resistance applied to the flexible hose 10 in the second insertion path 24b upstream of the curved base end 24d. The faucet device 6 can prevent the flexible hose 10 from bending in a direction different from the direction in which the flexible hose 10 is stored when the spout 12 is pushed back after being pulled out of the wall panel 4. Therefore, the faucet device 6 can easily store the flexible hose 10 in the wall panel 4. Furthermore, the faucet device 6 can improve the strength of the guide member 13 by providing ribs 27 on the guide member 13.

[0095] For example, it is possible to insert a retaining ring from the outside to the inside to secure the exterior component and the connecting component. However, in this case, the length of the inserted retaining ring must be considered, and the size of the spout in a plane perpendicular to the direction of water flow (hereinafter simply referred to as the "spout size") becomes large. Furthermore, if the size of the spout is reduced while considering the length of the retaining ring, for example, the flexible hose becomes thinner, and the cross-sectional area of ​​the flow path of the flexible hose becomes smaller, which may prevent water from being discharged from the spout in the desired manner.

[0096] In contrast, the faucet device 6 comprises a spout 12 that can be pulled out from the wall panel 4, and a flexible hose 10 that connects the spout 12 to a water supply pipe 14. The spout 12 comprises a tubular exterior member 30, a connecting member 31 that is connected to the front end of the flexible hose 10 that is inserted into the exterior member 30, and an engaging member 32 that is housed in the exterior member 30 upstream of the connecting member 31 in the flow direction of water discharged from the spout 12 and is provided between the exterior member 30 and the flexible hose 10. The engaging member 32 comprises a first engaging portion 40 that engages with the exterior member 30 and a second engaging portion 41 that engages with the connecting member 31 at a position different from the first engaging portion 40.

[0097] As a result, the faucet device 6 can reduce the thickness required to provide each engagement part by providing the first engagement part 40 that engages with the appearance member 30 and the second engagement part 41 that engages with the connection member 31 that connects to the flexible hose 10 in different locations. This allows the faucet device 6 to reduce the size of the spout 12. Furthermore, by reducing the size of the spout 12, the faucet device 6 can improve its design. Furthermore, the faucet device 6 can reduce the size of the spout 12 without, for example, making the flexible hose 10 thinner. Therefore, the faucet device 6 can discharge water from the spout 12 in a desired manner.

[0098] Additionally, the first engagement portion 40 engages with the appearance member 30 by snap-fitting.

[0099] As a result, the faucet device 6 can reduce the thickness of the portion where the engaging member 32 and the exterior member 30 engage, while still engaging the engaging member 32 and the exterior member 30. As a result, the faucet device 6 can reduce the size of the spout 12. Furthermore, the faucet device 6 can reduce the size of the spout 12 while preventing the flexible hose 10 from becoming thinner, for example. Furthermore, workers and the like can easily release the engagement between the engaging member 32 and the exterior member 30, making it easy to disassemble the faucet device 6. As a result, workers and the like can easily perform maintenance on the faucet device 6.

[0100] Additionally, the second engagement portion 41 abuts against the connection member 31 in the direction of water flow.

[0101] As a result, the water faucet device 6 can reduce the thickness of the portion where the engaging member 32 and the connecting member 31 engage while still engaging the engaging member 32 and the connecting member 31. As a result, the water faucet device 6 can reduce the size of the spout 12. Furthermore, the water faucet device 6 can reduce the size of the spout 12 while, for example, preventing the flexible hose 10 from becoming thinner. Furthermore, because the second engaging portion 41 abuts the connecting member 31 in the direction of water flow, when the engagement between the engaging member 32 and the appearance member 30 is released, the water faucet device 6 can release the engagement between the engaging member 32 and the connecting member 31 by, for example, moving the engaging member 32 upstream. This makes it easy for workers to disassemble the water faucet device 6, facilitating maintenance of the water faucet device 6.

[0102] The spout 12 is housed in the exterior member 30 and includes a water-spouting member 34 that spouts water, and a stopper 35 that is located downstream of the water-spouting member 34 in the direction of water flow and abuts against the water-spouting member 34. A groove 30b is formed in the inner wall of the exterior member 30 along the circumferential direction. The stopper 35 is fitted into the groove 30b.

[0103] As a result, the stopper 35 in the faucet device 6 can prevent the water discharge member 34 housed in the spout 12 and other components from coming out of the spout 12. Furthermore, the faucet device 6 can reduce the amount of protrusion of the stopper 35 that protrudes inward from the spout 12 by fitting the stopper 35 into a groove 30b provided in the inner wall of the exterior component 30. This makes it possible to reduce the visibility of the stopper 35 when the faucet device 6 is viewed from the direction of water discharge, for example. Furthermore, the faucet device 6 can prevent the water discharge member 34 from moving without having to insert a screw or the like from the outside to the inside of the exterior component 30. This allows the size of the spout 12 in the faucet device 6 to be reduced.

[0104] The groove 30b also has a notch 30c on the downstream side in the direction of water flow.

[0105] This allows a user or the like to remove stopper 35 from groove 30b via notch 30c. For example, a worker or the like can insert a thin pin into notch 30c to remove stopper 35 from groove 30b. This allows a worker or the like to easily perform maintenance on faucet device 6.

[0106] In the modified faucet device 6, the water discharge member 34 may be provided with an elastically deformable protrusion that protrudes outward from the front end side of the water discharge member 34, and the protrusion may be fitted into the groove portion 30b of the appearance member 30, thereby integrating the water discharge member 34 and the appearance member 30.
