[0003] [Patent Document 1] JP 2017-20305 A Summary of the Invention [Problem to be solved by the invention]

[0004] In addition to different water discharge forms, water discharge devices are also known that can discharge water with different properties from raw water, such as reformed water obtained by processing raw water. If such a function is further provided in the water discharge device of Patent Document 1, it is ideal to provide separate flow paths and water outlets for the raw water and reformed water from the viewpoint of the quality of the reformed water. However, in this case, in addition to the configurations for shower water discharge and straight water discharge, a flow path and water outlet for the reformed water are further required, which raises concerns about the size of the device.

[0005] The present disclosure has been made in consideration of the above-mentioned conventional situation, and has as its object to provide a water discharge device that can prevent an increase in size while ensuring convenience and quality of reformed water. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, a water discharge device according to one embodiment of the present disclosure comprises a raw water discharge section that can switch between either a shower-like or straight water discharge form and discharge only raw water supplied from a water supply source, and a modified water discharge section that discharges only modified water obtained by modifying the raw water, and the raw water discharge section is arranged around the modified water discharge section so as to surround the modified water discharge section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A first to sixth embodiment of the water discharger according to the present disclosure will be described with reference to the drawings. In the following description of each embodiment, a form in which each water discharger is attached to a kitchen counter 110 shown in FIG. 1 will be illustrated.

[0009] <Embodiment 1> The water discharge device 10 according to the first embodiment is connected to the downstream end of a water discharge pipe 90 in a water faucet device 100, as shown in Figs. 1 and 2. The water faucet device 100 is attached to a kitchen counter 110. The water faucet device 100 includes a water faucet body 60, a raw water operation unit 70, a reformed water operation unit 80, a water discharge pipe 90, and a water discharge device 10. The water faucet device 100 includes a water supply passage 1 communicating with a water supply source, a hot water supply passage 3 communicating with a hot water supply source, and a branch passage 5 branching off the water supply passage 1 and connected to a reformed water production unit 120 midway, which are all connected to each other, and hot water and reformed water flow in. The reformed water production unit 120 produces reformed water by reforming raw water, such as purified water.

[0010] The faucet device 100 discharges, as raw water, either a mixture of water flowing in from the water supply passage 1 and hot water flowing in from the hot water supply passage 3, or an unmixed mixture, from a raw water discharge section 14, described later, in the water discharge device 10. The faucet device 100 can discharge reformed water generated in the reformed water generation section 120 from a reformed water discharge section 12, described later, in the water discharge device 10.

[0011] The faucet body 60 has a central body portion 61, a right body portion 63, and a left body portion 65. When the faucet body 60 is attached to the kitchen counter 110, the central body portion 61 extends vertically in a straight line from the top surface of the kitchen counter 110 and has a cylindrical outer shape. When the faucet body 60 is attached to the kitchen counter 110, the right body portion 63 and the left body portion 65 extend in the left-right direction relative to the central body portion 61 and have a cylindrical outer shape. The central axis of the right body portion 63 and the central axis of the left body portion 65 extend horizontally on the same straight line.

[0012] The faucet body 60 incorporates a mixing valve with a water stop function (not shown) inside the right body portion 63. The mixing valve with a water stop function has two inlet ports communicating with the water supply passage 1 and the hot water supply passage 3, and one outlet port communicating with the raw water supply passage 7 of the discharge pipe 90. The mixing valve with a water stop function opens and closes the flow path connecting the water supply passage 1 and the hot water supply passage 3 with the raw water supply passage 7, changes the amount of raw water flowing out to the raw water supply passage 7, and changes the mixing ratio of hot and cold water flowing in from each of the water supply passage 1 and the hot water supply passage 3 to change the outflow temperature.

[0013] The raw water operating unit 70 is attached to the right end of the right-side main body 63 of the faucet main body 60. The raw water operating unit 70 has an operating unit main body 71 and an operating lever 73. The operating unit main body 71 is provided coaxially with the right-side main body 63 and has a cylindrical outer shape. The operating lever 73 extends radially outward from the outer circumferential surface of the operating unit main body 71. The raw water operating unit 70 is linked to a movable part of the mixing valve with water stop function. By operating the operating lever 73, the faucet device 100 can switch between stopping and discharging raw water from the raw water discharge unit 14, change the discharge flow rate, and change the discharge temperature.

[0014] The reformed water operation unit 80 is a contact-type sensor, and is provided on the left body portion 65 of the faucet body 60. The reformed water operation unit 80 is connected to send signals to a reformed water production unit 120, which will be described later. When the reformed water operation unit 80 of the faucet device 100 is operated, the reformed water production unit 120 produces reformed water. The reformed water produced in the reformed water production unit 120 is discharged from the reformed water discharge unit 12 via the reformed water supply passage 9.

[0015] The discharge pipe 90 is provided at the upper end of the central body portion 61 of the faucet body 60 so as to be rotatable around the central axis of the central body portion 61. The discharge pipe 90 has an upstream portion 91 and a downstream portion 93. The upstream portion 91 extends in a straight line vertically upward from the upper end of the central body portion 61. The downstream portion 93 is curved in an arc that protrudes upward from the upper end of the upstream portion 91. The downstream end opening of the discharge pipe 90 faces downward.

[0016] A raw water supply channel 7 and a reformed water supply channel 9 are arranged inside the discharge pipe 90. The raw water supply channel 7 communicates with the water supply channel 1 and the hot water supply channel 3 via a mixing valve with a water stop function (not shown), and raw water passes through the mixing valve. The reformed water supply channel 9 communicates directly with the branch channel 5, and reformed water generated in the reformed water generating unit 120 passes through the raw water supply channel 7.

[0017] In this embodiment, the raw water supply channel 7 and the reforming water supply channel 9 are formed by two flexible tubes 95, 97 inserted into the discharge pipe 90, as shown in Fig. 2. The two flexible tubes 95, 97 form a double pipe, forming two flow paths. The reforming water supply channel 9 is formed in the inner flexible tube 95. The raw water supply channel 7 is formed between the inner flexible tube 95 and the outer flexible tube 97. The flexible tubes 95, 97 can be pulled out from the downstream end of the discharge pipe 90 together with the water discharge device 10 removed from the downstream end of the discharge pipe 90.

[0018] As shown in FIG. 3, the water discharge device 10 has an overall cylindrical shape centered on the axis C. The water discharge device 10 is attached to a water discharge pipe 90 at one axial end, and discharges reformed water and raw water at the other axial end. The water discharge device 10 is detachably attached to the downstream end of the water discharge pipe 90. The water discharge device 10 can be used by being pulled out together with flexible tubes 95, 97 from the downstream end of the water discharge pipe 90. In the following description, the water discharge pipe 90 side, which is one axial end of the water discharge device 10, is also referred to as the upstream side, and the opposite side is also referred to as the downstream side.

[0019] The water discharge device 10 includes a reformed water flow path 11, a reformed water discharge section 12, a raw water flow path 13, and a raw water discharge section 14. The reformed water flow path 11 communicates with the reformed water supply path 9 on the discharge pipe 90 side at its upstream end, and the reformed water flowing in from the reformed water supply path 9 flows through it. The reformed water discharge section 12 discharges the reformed water that has flowed through the reformed water flow path 11. The raw water flow path 13 communicates with the raw water supply path 7 on the discharge pipe 90 side at its upstream end, and the raw water flowing in from the raw water supply path 7 flows through it. The raw water discharge section 14 discharges the raw water that has flowed through the raw water flow path 13. The raw water discharge section 14 is disposed around the reformed water discharge section 12 so as to surround the reformed water discharge section 12.

[0020] As shown in FIG. 4, the raw water discharge section 14 has a first straight water discharge section 15, a shower water discharge section 16, and a second straight water discharge section 17. The first straight water discharge section 15, the shower water discharge section 16, and the second straight water discharge section 17 each form a circular tubular region arranged concentrically by the water sprinkling member 30. The first straight water discharge section 15 is an example of a straight water discharge section according to the present disclosure. The first straight water discharge section 15 discharges raw water when the water discharge form from the raw water discharge section 14 is straight. The shower water discharge section 16 discharges the raw water when the water discharge form from the raw water discharge section 14 is shower-shaped. The shower water discharge section 16 is arranged surrounded by the first straight water discharge section 15. The second straight water discharge section 17, together with the first straight water discharge section 15, discharges raw water when the water discharge form from the raw water discharge section 14 is straight.

[0021] As shown in FIG. 4, the water discharger 10 includes a first opening / closing unit 18 and a second opening / closing unit 19. The first opening / closing unit 18 is an example of an opening / closing unit according to the present disclosure. The first opening / closing unit 18 opens and closes a first straight flow path 15A that communicates with the first straight water discharger 15. The first straight flow path 15A is an example of a straight flow path according to the present disclosure. The second opening / closing unit 19 opens and closes a second straight flow path 17A that communicates with the second straight water discharger 17. The water discharger 10 switches the water discharge form between a shower-like form and a straight-like form by the first opening / closing unit 18 and the second opening / closing unit 19 opening and closing the first straight flow path 15A and the second straight flow path 17A, respectively.

[0022] As shown in Figs. 3 to 5, the water discharge device 10 is configured with a pipe member 20, a water sprinkling member 30, a first inner cylinder member 41, a second inner cylinder member 42, a first outer cylinder member 51, a second outer cylinder member 52, etc., in terms of component configuration. All of these are arranged coaxially with respect to the axis C. The pipe member 20 is formed in a circular tube shape. The pipe member 20 is arranged with its central axis aligned with the axis C. The pipe member 20 is connected at its upstream end to a flexible tube 95 that forms the reforming water supply passage 9. The space inside the inner circumferential surface of the pipe member 20 is the reforming water flow path 11. The pipe member 20 forms a space on the outer circumferential surface that becomes the raw water flow path 13. That is, the water discharge device 10 forms two flow paths by double pipes, similar to the water discharge pipe 90 side.

[0023] As shown in FIG. 5, a flange portion 21 and a rib portion 22 are formed on the outer peripheral surface of the pipe member 20. The flange portion 21 is expanded radially outward from the outer peripheral surface at the downstream end of the pipe member 20 in a brim-like shape. As shown in FIG. 4, the downstream end surface 21A of the flange portion 21 is flat along a direction perpendicular to the central axis of the pipe member 20. A flat packing P1 is attached to the downstream end surface 21A. The flat packing P1 constitutes the second opening / closing portion 19 together with an upstream end portion 33A of the third cylindrical portion 33 described later. The upstream end surface 21B of the flange portion 21 expands gently from the outer peripheral surface of the pipe member 20 to the outer peripheral edge of the flange portion 21 in a cross-sectional arc shape. As a result, the flange portion 21 guides the raw water flowing along the outer peripheral surface of the pipe member 20 in the raw water flow passage 13 radially outward. The flange portion 21 is an example of a guide portion according to the present disclosure. The flange portion 21 guides the raw water flowing along the outer circumferential surface of the pipe member 20 in the axial direction of the pipe member 20 toward the first straight flow path 15A.

[0024] As shown in FIG. 5, the rib portion 22 extends along the central axis of the pipe member 20. A plurality of rib portions 22 are formed in the circumferential direction of the pipe member 20. The rib portion 22 rectifies the raw water flowing through the raw water flow path 13. Each rib portion 22 has a protruding portion 22A. The protruding portion 22A protrudes radially outward at the middle portion of the rib portion 22. A washer W is attached to the upstream end surface of each protruding portion 22A. One end of a coil spring C contacts the washer W. The other end of the coil spring C contacts a spring seat portion 41A of the first inner tube member 41, which will be described later. As a result, the coil spring C applies an elastic force in a direction in which the pipe member 20 moves relatively downstream with respect to the first inner tube member 41. The downstream end surface of the protruding portion 22A contacts the upper end surface of the second inner tube member 42.

[0025] As shown in FIG. 3, inside the pipe member 20, from the upstream side, a buffer section 23, a rectifying section 24, and an opening 25 are provided. The buffer section 23 is provided at the upstream end of the pipe member 20. The buffer section 23 temporarily retains the reforming water that has flowed from the reforming water supply passage 9 into the reforming water flow path 11, thereby suppressing pulsation in the discharged water. The rectifying section 24 is provided in the middle of the pipe member 20. The rectifying section 24 rectifies the flow of the reforming water. The opening 25 is formed at the downstream end of the pipe member 20. The opening 25 constitutes the reforming water discharge section 12 in the water discharge device 10.

[0026] 6 and 7, the water sprinkling member 30 is provided in the raw water discharge section 14 of the water discharger 10. The water sprinkling member 30 is provided so as to be freely movable relative to the pipe member 20 in a direction along the axis C, which is coaxial with the axis of the pipe member 20. By moving the water sprinkling member 30 in the direction of the axis C, the water discharger 10 switches the discharge form of the raw water discharged from the raw water discharge section 14 between straight water spouting and shower water spouting.

[0027] 6 and 7, the water sprinkling member 30 has a first tubular portion 31, a second tubular portion 32, a third tubular portion 33, a water sprinkling portion 34, and a connecting rib 35. The first tubular portion 31, the second tubular portion 32, and the third tubular portion 33 each have a cylindrical shape. The first tubular portion 31, the second tubular portion 32, and the third tubular portion 33 are concentrically arranged.

[0028] The first cylindrical portion 31 is disposed on the outermost side of the three cylindrical portions 31, 32, and 33. The first straight flow passage 15A is formed on the inner peripheral surface side of the first cylindrical portion 31. The first cylindrical portion 31 has a reduced diameter portion 31A, a protrusion 31B, and a notch portion 31C. The reduced diameter portion 31A is formed by bending the downstream end portion of the first cylindrical portion 31 inwardly to have a hook-like cross section. The inner diameter of the reduced diameter portion 31A is smaller than the inner diameter of the portion of the first cylindrical portion 31 above the reduced diameter portion 31A. As a result, the reduced diameter portion 31A guides the raw water flowing along the inner peripheral surface of the first cylindrical portion 31 forming the first straight flow passage 15A radially inward. The protrusion 31B is disposed in a female thread portion 52A (described later) formed on the inner peripheral surface of the second outer cylindrical member 52. The protrusion 31B moves in the female thread portion 52A by rotating the second outer cylindrical member 52.

[0029] As shown in FIG. 5, the notch 31C is formed by cutting out the upstream end of the first cylindrical portion 31 in the axial direction. A plurality of notches 31C are provided in the circumferential direction of the first cylindrical portion 31. A convex portion 42A (described later) of the second inner cylindrical member 42 is disposed in each notch 31C. The notch 31C has a width slightly larger than the circumferential width of the convex portion 42A, and a length sufficiently larger than the axial length of the convex portion 42A. Due to the action of the notch 31C and the convex portion 42A, the water sprinkling member 30 is only permitted to move axially relative to the second inner cylindrical member 42, and relative rotation about the axis is prevented.

[0030] 6 and 7, the second cylindrical portion 32 is disposed inside the first cylindrical portion 31. The second cylindrical portion 32 forms a first straight flow path 15A between itself and the first cylindrical portion 31. The upstream end portion 32A of the second cylindrical portion 32 constitutes the first opening / closing portion 18. When the water sprinkling member 30 moves axially upstream, the upstream end portion 32A of the second cylindrical portion 32 comes into contact with a lip packing P2, which will be described later, and closes the first straight flow path 15A.

[0031] The third cylindrical portion 33 is disposed at the innermost position among the three cylindrical portions 31, 32, and 33. The downstream end of the pipe member 20 is inserted into the inside of the third cylindrical portion 33. A gap is formed between the inner peripheral surface of the third cylindrical portion 33 and the outer peripheral surface of the pipe member 20. This gap is the second straight flow path 17A that communicates with the second straight water spouting portion 17. The upstream end 33A of the third cylindrical portion 33 constitutes the second opening / closing portion 19. The upstream end 33A of the third cylindrical portion 33 comes into contact with the flat packing P1 as the sprinkling member 30 moves axially upstream, thereby closing the second straight flow path 17A.

[0032] The sprinkler section 34 is annular and connects the downstream end of the second tube section 32 and the downstream end of the third tube section 33. The sprinkler section 34 forms a sprinkler surface 34A and a plurality of sprinkler holes 34B. The sprinkler surface 34A is exposed in the direction of discharge of raw water in the raw water discharge section 14. The plurality of sprinkler holes 34B open in the sprinkler surface 34A. The plurality of sprinkler holes 34B communicate with the shower flow path 16A connected to the raw water flow path 13 on the upstream side. The sprinkler surface 34A smoothly continues to the outer peripheral surface of the second tube section 32 on the outer peripheral side. The inner peripheral side portion of the sprinkler surface 34A smoothly continues to the inner peripheral surface of the third tube section 33. The sprinkler surface 34A is inclined forward in the discharge direction of raw water in the raw water discharge section 14 from the outer peripheral side toward the center side.

[0033] The connecting rib 35 connects the first tubular portion 31 and the second tubular portion 32. A plurality of connecting ribs 35 are provided at equal intervals in the circumferential direction.

[0034] As shown in Fig. 3 and Fig. 5, the first inner cylinder member 41 and the second inner cylinder member 42 are each formed in a cylindrical shape. The first inner cylinder member 41 and the second inner cylinder member 42 are fixedly connected in the axial direction with the first inner cylinder member 41 on the upstream side and the second inner cylinder member 42 on the downstream side. The first inner cylinder member 41 and the second inner cylinder member 42 in the connected state are prevented from coming off in the axial direction by a retainer 43. The first inner cylinder member 41 and the second inner cylinder member 42 house the pipe member 20 therein. The first inner cylinder member 41 and the second inner cylinder member 42 are arranged coaxially with the pipe member 20. A gap between the inner peripheral surface of the first inner cylinder member 41 and the second inner cylinder member 42 and the outer peripheral surface of the pipe member 20 functions as a raw water flow path 13.

[0035] As shown in FIG. 3, the first inner cylinder member 41 has a spring seat 41A. The spring seat 41A is formed by making a portion of the inner circumferential portion of the first inner cylinder member 41 smaller in diameter than the other portions. The other end of the coil spring C that imparts axial elastic force to the pipe member 20 contacts the spring seat 41A. As shown in FIG. 5, the second inner cylinder member 42 has a convex portion 42A. The convex portion 42A is formed to protrude in a convex shape from the outer circumferential surface of the second inner cylinder member 42. The convex portion 42A is disposed inside the cutout portion 31C in the water sprinkler member 30.

[0036] 4 and 5, a lip packing P2 is attached to the downstream end of the second inner cylinder member 42. The outer peripheral edge of the lip packing P2 is in watertight contact with the inner peripheral surface of the first cylinder portion 31 of the water sprinkling member 30. The downstream end face of the lip packing P2 comes into contact with the upstream end portion 32A of the second cylinder portion 32 when the water sprinkling member 30 moves axially upstream.

[0037] As shown in Fig. 3 and Fig. 5, the first outer cylinder member 51 and the second outer cylinder member 52 are each formed in a cylindrical shape. The first outer cylinder member 51 and the second outer cylinder member 52 are disposed outside the first inner cylinder member 41 and the second inner cylinder member 42. The first outer cylinder member 51 and the second outer cylinder member 52 are disposed side by side in the axial direction, with the first outer cylinder member 51 on the upstream side and the second outer cylinder member 52 on the downstream side. The first outer cylinder member 51 is disposed fixedly relative to the first inner cylinder member 41.

[0038] As shown in FIG. 4 and FIG. 5, the second outer cylinder member 52 is attached to the second inner cylinder member 42 by an E-type stop ring E. The E-type stop ring E restricts the second outer cylinder member 52 from moving in the axial direction relative to the second inner cylinder member 42, but allows rotation around the axis. The second inner cylinder member 42 moves the sprinkling member 30 in the axial direction by rotating around the axis. That is, the second inner cylinder member 42 functions as a switching operation unit when switching the spouting mode of the raw water. Specifically, a female screw portion 52A is formed on the inner peripheral surface of the second inner cylinder member 42. A protrusion 31B formed on the outer peripheral surface of the sprinkling member 30 is arranged on the female screw portion 52A. The second inner cylinder member 42 moves the entire sprinkling member 30 including the protrusion 31B in the axial direction by rotating around the axis. A knurled portion 52B is formed on the outer peripheral surface of the second inner cylinder member 42. The knurled portion 52B is a portion on which the user of the water discharger 10 places his / her finger when rotating the second outer cylinder member 52.

[0039] The operation of the water discharge device 10 configured as above will be described. In the water discharge device 10, when the reforming water operating unit 80 is operated, the reforming water generating unit 120 generates reforming water. The reforming water generated in the reforming water generating unit 120 flows through the reforming water supply passage 9 and is introduced into the reforming water flow path 11 inside the pipe member 20. The reforming water introduced into the reforming water flow path 11 is buffered and rectified through the buffering unit 23 and the rectifying unit 24, and then discharged from the reforming water discharge unit 12.

[0040] When the raw water operating section 70 is operated, the water discharge device 10 sends hot water and cold water mixed in a mixing valve (not shown) to the raw water supply channel 7 as raw water. The raw water that has flowed through the raw water supply channel 7 is introduced into the raw water flow path 13 and discharged from the raw water discharge section 14. This raw water discharge section 14 is arranged around the reformed water discharge section 12 so as to surround the reformed water discharge section 12. Therefore, the water discharge device 10 has a neat and good appearance. Because the raw water discharge section 14 is arranged around the reformed water discharge section 12, the water discharge device 10 discharges water from the same place in the same direction both when discharging reformed water and when discharging raw water, making it easy to use.

[0041] The water discharge device 10 can switch the water discharge form from the raw water discharge section 14 to either a shower-like form or a straight-like form. This switching is performed by opening and closing the first straight flow path 15A and the second straight flow path 17A by the first opening and closing section 18 and the second opening and closing section 19. The first straight flow path 15A and the second straight flow path 17A are opened and closed by moving the water sprinkling member 30 in the axial direction by rotating the second outer cylinder member 52 around its axis. The water sprinkling member 30 moves in the axial direction between a first position shown in FIG. 7 and a second position shown in FIG. 8. The first position is a position where the water sprinkling member 30 has moved from the second position to the downstream side, which is one side of the axial direction. Conversely, the second position is a position where the water sprinkling member 30 has moved from the first position to the upstream side, which is the other side of the axial direction.

[0042] When the sprinkling member 30 is in the first position shown in FIG. 7, the water discharger 10 is in a state in which the first opening / closing section 18 and the second opening / closing section 19 open the first straight flow path 15A and the second straight flow path 17A. In this state, the water discharger 10 discharges raw water in a straight water discharge form from the raw water discharge section 14. In detail, when the sprinkling member 30 is in the first position, the raw water flow path 13 is in a state in which it is connected to each of the straight water discharge sections 15, 17 and the shower water discharge section 16. Therefore, the raw water that has flowed through the raw water flow path 13 can flow into each of the first straight flow path 15A, the shower flow path 16A, and the second straight flow path 17A. Of these flow paths 15A, 16A, and 17A, the first straight flow path 15A is a flow path that is connected to the first straight water discharge section 15, which is the outermost part in the raw water discharge section 14.

[0043] The first straight flow path 15A is formed between the first tubular portion 31 and the second tubular portion 32 of the water sprinkling member 30. The raw water that flows into the first straight flow path 15A flows along the outer circumferential surface of the second tubular portion 32. The outer circumferential surface of the second tubular portion 32 is smoothly connected to the sprinkling surface 34A of the sprinkling portion 34 at the downstream end. The sprinkling surface 34A is inclined toward the center side and forward in the discharge direction of the raw water in the raw water discharge portion 14. Therefore, the raw water that flows along the outer circumferential surface of the second tubular portion 32 further flows along the surface of the sprinkling surface 34A in the sprinkling portion 34 due to the action of surface tension. As a result, the raw water discharged from the first straight water discharge portion 15 forms a flow toward the center side of the raw water discharge portion 14 along the surface of the sprinkling surface 34A.

[0044] Similarly, the raw water flowing through the first straight flow path 15A flows along the inner circumferential surface of the first tubular portion 31. The flow direction of the raw water flowing along the inner circumferential surface of the first tubular portion 31 is changed by the reduced diameter portion 31A at the downstream end of the first tubular portion 31, and the raw water is guided toward the center of the raw water discharge portion 14. In this way, the first straight water discharge portion 15 forms a flow of raw water toward the center of the raw water discharge portion 14.

[0045] These flows of raw water join together by dredging up the raw water discharged from each of the shower water discharge section 16 and the second straight water discharge section 17, which are closer to the center than the first straight water discharge section 15. The raw water thus joined forms a straight water discharge. As described above, when the first opening / closing section 18 and the second opening / closing section 19 open the respective straight flow paths 15A, 17A, the water discharge device 10 forms a straight water discharge in which the raw water discharged from each of the straight water discharge sections 15, 17 and the shower water discharge section 16 join together.

[0046] 7, when the sprinkler member 30 is in the first position, raw water that has flowed through the raw water flow path 13 is guided to the first straight flow path 15A by the flange portion 21. Therefore, in the water discharge device 10, when the raw water discharged from the raw water discharge portion 14 has a straight discharge form, a sufficient flow rate of raw water is supplied to the first straight flow path 15A. As a result, a sufficient flow rate of raw water is discharged from the first straight water discharge portion 15 toward the center of the raw water discharge portion 14, and the raw water discharged from the shower water discharge portion 16 and the second straight water discharge portion 17 can be suitably merged.

[0047] In contrast, when the water sprinkler member 30 is in the second position shown in FIG. 8, the water discharger 10 is in a state in which the first opening / closing part 18 and the second opening / closing part 19 close the first straight flow path 15A and the second straight flow path 17A. Specifically, when the water sprinkler member 30 moves from the first position to the other upstream direction of the axial direction of the pipe member 20 and reaches the second position, the upstream end 32A of the second tubular part 32 in the water sprinkler member 30 contacts the flat packing P1 in a watertight manner, and the upstream end 33A of the third tubular part 33 contacts the lip packing P2 in a watertight manner. As a result, the first opening / closing part 18 and the second opening / closing part 19 close the first straight flow path 15A and the second straight flow path 17A. In this state, the water discharger 10 discharges raw water from the raw water discharge part 14 in a shower-like discharge form.

[0048] When the sprinkling member 30 is in the second position, the raw water flow path 13 is not connected to the first straight flow path 15A and the second straight flow path 17A, and is connected only to the shower water outlet 16. Therefore, the raw water that has flowed through the raw water flow path 13 can only flow into the shower flow path 16A. Therefore, the raw water that has flowed through the raw water flow path 13 is discharged only from the multiple sprinkling holes 34B via the shower flow path 16A, forming the shower water outlet. As described above, in the water outlet device 10, when the first opening / closing unit 18 and the second opening / closing unit 19 close the respective straight flow paths 15A, 17A, the raw water discharged only from the shower water outlet 16 forms the shower water outlet.

[0049] As shown in FIG. 9, in the process in which the water sprinkling member 30 moves from the first position to the second position, the second opening and closing part 19 closes the second straight flow path 17A before the first opening and closing part 18 closes the first straight flow path 15A. As described above, the second opening and closing part 19 is configured to have the upstream end part 33A of the third tubular part 33 in the water sprinkling member 30. The second opening and closing part 19 closes the second straight flow path 17A by the upstream end part 33A of the third tubular part 33 contacting the flat packing P1. The pipe member 20 is movable along the axial direction, and is given an elastic force in the axial direction by the coil spring C. The upstream end part 33A of the third tubular part 33 in the water sprinkling member 30 is pressed against the flat packing P1 while resisting this elastic force. The water sprinkler member 30 moves further upstream as the upstream end 33A of the third tubular portion 33 pushes the pipe member 20 upstream together with the flat gasket P1, and the upstream end 32A of the second tubular portion 32 contacts the downstream end face of the lip gasket P2.

[0050] That is, in the water discharger 10, the water sprinkler member 30 moves the pipe member 20 upstream while maintaining the state in which the upstream end 33A of the third tubular portion 33 and the flat packing P1 are in contact with each other by the elastic force of the coil spring C, and brings the upstream end 32A of the second tubular portion 32 into contact with the downstream end face of the lip packing P2. This allows the water discharger 10 to preferably achieve both the blocking of the first straight flow path 15A by the first opening / closing portion 18 and the blocking of the second straight flow path 17A by the second opening / closing portion 19.

[0051] As described above, the water discharge device 10 according to the first embodiment includes the raw water discharge section 14 and the reformed water discharge section 12. The raw water discharge section 14 can discharge raw water supplied from a water supply source (not shown) via the water supply passage 1 by switching between a shower-like discharge form and a straight discharge form. The reformed water discharge section 12 discharges reformed water obtained by reforming the raw water. The raw water discharge section 14 is disposed around the reformed water discharge section 12 so as to surround the reformed water discharge section 12.

[0052] In this way, the water discharge device 10 can switch the water discharge form from the raw water discharge section 14 between a shower shape and a straight shape. The water discharge device 10 is provided with the reformed water discharge section 12 in addition to the raw water discharge section 14. The water discharge device 10 is convenient because it can discharge water in a plurality of water discharge forms and can select a plurality of water types to discharge. In the water discharge device 10, the raw water discharge section 14 and the reformed water discharge section 12 are provided separately. Therefore, the reformed water discharged from the reformed water discharge section 12 is not mixed with the raw water, and good quality is ensured. The reformed water discharge section 12 is surrounded by the raw water discharge section 14. Therefore, the water discharge device 10 can realize a compact configuration compared to a case where each discharge section is arranged side by side, such as front to back or left to right, or a case where each discharge section is provided in a separate water discharge device. Therefore, the water discharge device 10 can suppress an increase in size while ensuring convenience and quality of the reformed water.

[0053] In the water discharge device 10, the raw water discharge section 14 has a shower water discharge section 16 and a first straight water discharge section 15 as a straight water discharge section. The shower water discharge section 16 discharges raw water when the water discharge form is a shower shape. The first straight water discharge section 15 discharges raw water when the water discharge form is a straight shape. The first straight water discharge section 15 is arranged around the shower water discharge section 16 so as to surround the shower water discharge section 16. Therefore, the water discharge device 10 can arrange the shower water discharge section 16 and the first straight water discharge section 15 in a compact manner.

[0054] In the water discharge device 10, the shower water discharge section 16 forms a water spray surface 34A on which a plurality of water spray holes 34B are formed. The water spray surface 34A is a surface exposed in the direction of discharge of raw water in the raw water discharge section 14, and is inclined forward in the discharge direction from the outer periphery toward the center. The first straight water discharge section 15 is provided on the outer periphery of the shower water discharge section 16, and forms a flow of raw water toward the center of the raw water discharge section 14 along the water spray surface 34A. Therefore, the raw water discharged from the first straight water discharge section 15 converges toward the center, realizing a neat straight water discharge.

[0055] The water discharger 10 has a first opening / closing section 18 as an opening / closing section. The first opening / closing section 18 opens and closes the first straight flow path 15A as a straight flow path that communicates with the first straight water discharger 15. When the first opening / closing section 18 closes the first straight flow path 15A, the raw water discharger 14 discharges raw water only from the shower water discharger 16 to form shower water. When the first opening / closing section 18 opens the first straight flow path 15A, the raw water discharger 14 forms straight water discharge in which the raw water discharged from each of the first straight water discharger 15 and the shower water discharger 16 join together. In this way, the water discharger 10 realizes straight water discharge by using the water discharged from the shower water discharger 16. Therefore, the water discharger 10 can be made more compact than when the water discharger for shower water discharge and the water discharger for straight water discharge are completely switched.

[0056] The water discharge device 10 includes a sprinkling member 30 and a pipe member 20. The sprinkling member 30 has a plurality of sprinkling holes 34B formed therein, forming a shower water discharge section 16. The pipe member 20 is provided penetrating the sprinkling member 30, and has a reformed water discharge section 12 at its tip. The sprinkling member 30 is provided so as to be movable along the axial direction of the pipe member 20. The first straight water discharge section 15 is provided on the outer periphery side of the sprinkling member 30. The raw water discharge section 14 includes a second straight water discharge section 17. The second straight water discharge section 17 is formed between the sprinkling member 30 and the pipe member 20, and discharges raw water when the water discharge form is straight. The water discharge device 10 includes a second opening / closing section 19 in addition to the first opening / closing section 18. The second opening / closing section 19 opens and closes a second straight flow path 17A that communicates with the second straight water discharge section 17. The first opening / closing unit 18 and the second opening / closing unit 19 open the first straight flow path 15A and the second straight flow path 17A, respectively, as the sprinkling member 30 moves in one axial direction. The first opening / closing unit 18 and the second opening / closing unit 19 close the first straight flow path 15A and the second straight flow path 17A, respectively, as the sprinkling member 30 moves in the other axial direction. In this way, the water discharger 10 can achieve straight water discharge by utilizing water discharged from the gap between the sprinkling member 30 and the pipe member 20. When shower water is discharged, the second straight flow path 17A is closed by the second opening / closing unit 19, so that the water discharger 10 can achieve a neat shower water discharge.

[0057] In the water discharger 10, the second opening / closing part 19 closes the second straight flow path 17A before the first opening / closing part 18 closes the first straight flow path 15A. This allows the water discharger 10 to achieve regular straight water discharge and shower water discharge.

[0058] For example, when switching from straight water spouting to shower water spouting, if the first straight water spouting section 15 is stopped first, water will be spouted from the shower water spouting section 16 and the second straight water spouting section 17, and at that point, it may be mistakenly recognized that the water spouting has been switched to shower water spouting, and the switching operation may be interrupted. In contrast, if the second straight water spouting section 17 is stopped first, it is easy to recognize that the water is straight water spouting while the first straight water spouting section 15 is spouting. For this reason, the water spouting device 10 can continue the switching operation until the straight water spouting desired by the user is generated. In this way, the water spouting device 10 can urge the user to complete the switching operation from straight water spouting to shower water spouting, and by performing the complete switching operation, it is possible to realize neat straight water spouting and shower water spouting.

[0059] In the water discharger 10, the pipe member 20 is movable along the axial direction and is given an elastic force in one axial direction. The second opening / closing part 19 closes the second straight flow path 17A by the water sprinkling member 30 moving in the other axial direction as if pushing the pipe member 20 back in the other axial direction against the elastic force. In this way, in the water discharger 10, the second opening / closing part 19 closes the second straight flow path 17A by utilizing the elastic force, and the pipe member 20 is moved in the axial direction while maintaining the closed state, so that the first opening / closing part 18 can reliably close the second straight flow path 17A. As a result, the water discharger 10 can reliably close the first straight flow path 15A and the second straight flow path 17A by the two opening / closing parts 18, 19, and can realize a neat shower water discharge.

[0060] The water discharger 10 is provided with a flange portion 21 on the pipe member 20. The flange portion 21 guides the raw water flowing through the raw water flow path 13 to the first straight flow path 15A, which serves as a straight flow path. In other words, the flange portion 21 functions as a guide portion according to the present disclosure. Therefore, the water discharger 10 ensures a sufficient flow rate of raw water to be circulated to the first straight flow path 15A. This sufficient flow rate of raw water flows toward the center along the spray surface 34A, and scoops up and joins the raw water from the shower water discharger, thereby achieving neat, straight water discharge.

[0061] <Embodiment 2> The water discharger according to the second embodiment differs from the water discharger according to the first embodiment in that it is provided with a water discharge member having a water discharge surface of a different shape. In the following description, the same components as those in the first embodiment are given the same reference numerals and redundant description will be omitted.

[0062] The water discharger 210 according to the second embodiment includes a water sprinkler member 230, as shown in Fig. 10. In the water sprinkler member 230, the water sprinkler surface 234A is formed in a U-shaped cross section that protrudes most in the direction of discharge of raw water at the center between the second tubular portion 32 and the third tubular portion 33. In the water sprinkler device 210 including such a water sprinkler member 230, the first straight water spouting section 15 forms a flow of raw water toward the center of the raw water discharge section 14 along the surface of the water sprinkler surface 234A, and the second straight water spouting section 17 forms a flow of raw water toward the outside of the raw water discharge section 14 along the surface of the water sprinkler surface 234A.

[0063] The water discharger 210 configured as described above can suppress enlargement while ensuring convenience and quality of reformed water, similar to the first embodiment. In the water discharger 210, the first straight water discharger 15 and the second straight water discharger 17 discharge raw water in directions in which they collide with each other, so that the flows of raw water from the straight water dischargers 15, 17 can be reliably joined together. As a result, the water discharger 210 can realize a more ordered straight water discharge.

[0064] <Embodiment 3> The water discharger according to the third embodiment differs from the water discharger according to the first embodiment in that a seal member is provided between the tubular member and the water spray member. In the following description, the same components as those in the first embodiment are given the same reference numerals and redundant description will be omitted.

[0065] As shown in FIG. 11, the water discharger 310 according to the third embodiment is provided with a seal member P3. The seal member P3 constantly seals the gap between the outer peripheral surface of the pipe member 20 and the inner peripheral surface of the third tube portion 33 of the water sprinkler member 30 in a water-tight manner. That is, the water discharger 310 does not have a second straight water discharge section, and the raw water discharge section 14 is formed by the first straight water discharge section 15 and the shower water discharge section 16. Since the water discharger 310 does not have a second straight water discharge section, it does not have a flow path communicating with the second straight water discharge section, and a configuration such as a second opening and closing section for opening and closing this flow path is not required. Since the water discharger 310 does not have a second opening and closing section, a configuration that allows the pipe member 20 to move freely in the axial direction, a configuration for applying elastic force to the pipe member 20 in the axial direction, etc. are also not required.

[0066] The water discharge device 310 configured as described above can suppress an increase in size while ensuring convenience and quality of reformed water, similar to the first embodiment. The water discharge device 310 does not form a second straight water discharge section by providing a seal member P3 that water-tightly seals the gap between the outer circumferential surface of the pipe member 20 and the inner circumferential surface of the third tubular portion 33 in the sprinkler member 30. As a result, the water discharge device 310 does not require a configuration related to the second straight water discharge section. Therefore, the water discharge device 310 can be simplified in configuration.

[0067] <Embodiment 4> The water discharger according to the fourth embodiment differs from the water discharger according to the first embodiment in that a configuration equivalent to a water sprinkler member is integrated with a tubular member. In the following description, the same components as those in the first embodiment are given the same reference numerals and redundant description will be omitted.

[0068] The water discharger 410 according to the fourth embodiment includes a pipe member 420 as shown in FIG. 12. The pipe member 420 is integrally provided with a configuration corresponding to the water sprinkler member 30 according to the first embodiment. In detail, the pipe member 420 has a configuration similar to that of the first tubular portion 31, the second tubular portion 32, the third tubular portion 33, the water sprinkler portion 34, and the connecting rib 35 of the first embodiment. The pipe member 420 has a configuration in which the third tubular portion 33 is connected to the outer circumferential surface of the lower end portion. Therefore, the water discharger 410 does not have a configuration corresponding to the second straight water discharger, the second straight flow path, the second opening and closing portion, etc. It can be said that the water discharger 410 has a configuration in which the raw water discharger 14 is configured by the first straight water discharger 15 and the shower water discharger 16, as in the third embodiment.

[0069] In the case of the water discharger 410 of the fourth embodiment, when switching between shower water discharge and straight water discharge, the entire pipe member 420 moves in the axial direction. This opens and closes the first straight flow path 15A by the first opening and closing part 18. Since the water discharger 410 does not have a second opening and closing part, a configuration for applying an elastic force in the axial direction to the tubular member is not required.

[0070] The water discharge device 410 configured as described above can suppress an increase in size while ensuring convenience and quality of reformed water, similar to the first embodiment. The water discharge device 410 includes the pipe member 420 that integrates a configuration equivalent to a water sprinkling member, and thus does not form a second straight water discharge section, and therefore does not require a configuration related to the second straight water discharge section. Therefore, the water discharge device 410 can be simplified in configuration.

[0071] <Embodiment 5> The water discharger according to the fifth embodiment differs from the water dischargers of the above-mentioned embodiments in the mechanism for switching between shower water discharge and straight water discharge. In the following description, the same components as those of the above-mentioned embodiments are given the same reference numerals and redundant description will be omitted.

[0072] 13 and 14, the water discharge device 510 according to the fifth embodiment includes a raw water discharge section 514. The raw water discharge section 514 is disposed around the reformed water discharge section 12 so as to surround the reformed water discharge section 12. The raw water discharge section 514 has a straight water discharge section 515 and a shower water discharge section 516. The straight water discharge section 515 is disposed around the shower water discharge section 516 so as to surround the shower water discharge section 516.

[0073] The water discharge device 510 includes a water sprinkling member 530 and a pipe member 520. The pipe member 520 is cylindrical and forms a reforming water flow path 11 inside. The pipe member 520 has a reforming water discharge section 12 at its tip. The pipe member 520 is provided to penetrate the water sprinkling member 530. A raw water flow path 513 is formed on the outer peripheral surface side of the pipe member 520. The downstream end of the raw water flow path 513 is blocked by a blocking plate section 513A. A communication hole 513B is formed in the blocking plate section 513A. The raw water flowing through the raw water flow path 513 can flow downstream only from the communication hole 513B. A plurality of communication holes 513B are formed at equal intervals around the axis C.

[0074] The water sprinkling member 530 is provided in the raw water discharge section 514 of the water discharger 510. The water sprinkling member 530 is provided to the pipe member 520 so as to be rotatable about an axis C that is coaxial with the axis of the pipe member 520. The water discharger 510 switches the discharge form of the raw water discharged from the raw water discharge section 514 between straight water discharge and shower water discharge by rotating the water sprinkling member 530 about the axis C.

[0075] The water sprinkling member 530 has a first tube portion 531, a second tube portion 532, a third tube portion 533, and a water sprinkling portion 534. The first tube portion 531, the second tube portion 532, and the third tube portion 533 are each cylindrical. The water sprinkling member 530 has the first tube portion 531, the second tube portion 532, and the third tube portion 533 arranged concentrically from the outside. The first tube portion 531 and the second tube portion 532 are connected at a distance by a connecting rib (not shown). The gap between the first tube portion 531 and the second tube portion 532 is a straight flow path 515A. The space between the second tube portion 532 and the third tube portion 533 is a shower flow path 516A. The third tube portion 533 is connected to the downstream end of the second tube portion 532 by the water sprinkling portion 534. The downstream end of third cylindrical portion 533 extends downstream further than the downstream end of pipe member 520. Spray portion 534 has spray surface 534A. Spray surface 534A is flat and extends in a direction perpendicular to axis C.

[0076] A perforated plate 536 is attached to the water sprinkling member 530. This perforated plate 536 functions as a guide portion according to the present disclosure. The perforated plate 536 is in the shape of a disk formed with an outer diameter equal to that of the first cylindrical portion 531. The perforated plate 536 is attached to the upstream end of the water sprinkling member 530 so as to block the shower channel 516A from the upstream side. The perforated plate 536 is attached so as not to be movable relative to the water sprinkling member 530. As shown in FIG. 14, the perforated plate 536 forms through holes 536A. The through holes 536A are formed at equal intervals around the axis C with the same number and pitch diameter as the communication holes 513B.

[0077] Water sprinkling member 530 is connected to second outer cylinder member 52 on the outer circumferential surface side of first cylinder portion 531. As a result, water sprinkling member 530 rotates about axis C in response to rotation of second outer cylinder member 52. Perforated plate 536 is attached so as to be immovable relative to water sprinkling member 530, and therefore rotates in conjunction with the rotation of water sprinkling member 530 about axis C. As a result, the positions of multiple through holes 536A formed in perforated plate 536 about axis C are changed.

[0078] The water sprinkling member 530 is rotatable about the axis C between a first position shown in FIG. 13 and a second position shown in FIG. 14. When the water sprinkling member 530 is in the first position, the positions of the through holes 536A in the perforated plate 536 about the axis C are shifted from the positions of the communication holes 513B about the axis C. When the positions of the through holes 536A in the perforated plate 536 about the axis C are shifted from the positions of the communication holes 513B about the axis C, the water spouting device 510 can collide the raw water spouting from the communication holes 513B with the perforated plate 536 and introduce it into the straight flow path 515A on the outer periphery side. That is, the raw water spouting from the communication holes 513B is guided to the straight flow path 515A by the perforated plate 536. As a result, the water spouting device 510 spouts the raw water from the raw water discharge part 514 in a straight water discharge form.

[0079] When the water spouting member 530 is in the second position, the positions of the plurality of through holes 536A in the perforated plate 536 about axis C match the positions of the plurality of communication holes 513B about axis C. When the positions of the plurality of through holes 536A in the perforated plate 536 about axis C match the positions of the plurality of communication holes 513B about axis C, the water spouting device 510 can introduce the raw water spouting from the communication hole 513B into the downstream shower flow path 516A via the through hole 536A. This allows the water spouting device 510 to spout raw water from the raw water discharge portion 514 in a shower-like water spouting form.

[0080] The water discharger 510 having the above configuration can suppress an increase in size while ensuring convenience and quality of reformed water, similar to the first embodiment. The water discharger 510 can switch between shower water discharge and straight water discharge without providing an opening / closing section or the like. Therefore, the water discharger 510 can be simplified in configuration.

[0081] <Embodiment 6> The water discharger according to the sixth embodiment differs from the water dischargers according to the above-mentioned embodiments in terms of the arrangement of the shower water discharger and the straight water discharger in the raw water discharger. In the following description, the same components as those in the above-mentioned embodiments are given the same reference numerals and the duplicated description will be omitted.

[0082] As shown in Figures 15 and 16, the water discharge device 610 according to the sixth embodiment includes a raw water discharge section 614. The raw water discharge section 614 is disposed around the reformed water discharge section 12 so as to surround the reformed water discharge section 12. The raw water discharge section 614 has a straight water spouting section 615 and a shower water spouting section 616. In the raw water discharge section 614, the straight water spouting section 615 is disposed closer to the axis C than the shower water spouting section 616. That is, the raw water discharge section 614 has the shower water spouting section 616 disposed around the straight water spouting section 615 so as to surround the straight water spouting section 615.

[0083] The water discharger 610 includes a water sprinkling member 630 and a pipe member 520 similar to that of the fifth embodiment. The water sprinkling member 630 is provided in the raw water discharge section 614 of the water discharger 610. The water sprinkling member 630 is provided to the pipe member 520 so as to be rotatable about an axis C that is coaxial with the axis of the pipe member 520. The water discharger 610 switches the discharge form of the raw water discharged from the raw water discharge section 614 between straight water discharge and shower water discharge by rotating the second outer tube member 52 to rotate the water sprinkling member 630 about the axis C. In the water discharger 610, the water sprinkling member 630 is rotated about the axis C to switch the discharge form of the raw water, similar to the water sprinkling member 530 of the fifth embodiment.

[0084] In the water spray member 630, the gap between the first cylindrical portion 631 and the second cylindrical portion 632 is the shower flow path 616A. The water spray portion 634 is provided between the first cylindrical portion 631 and the second cylindrical portion 632. The space between the second cylindrical portion 632 and the outer circumferential surface of the pipe member 520 is the straight flow path 615A. For the sake of molding convenience, a flow straightening member 637, which is separate from the water spray member 630, is attached to the space that forms this straight flow path 615A.

[0085] The water sprinkling member 630 is provided with a baffle plate portion 636. This baffle plate portion 636 functions as a guide portion according to the present disclosure. The baffle plate portion 636 is provided at the upstream end of the water sprinkling member 630 so as to cover the straight flow path 615A. As shown in FIG. 16, the baffle plate portion 636 has a plurality of fan-shaped openings 636A formed at equal intervals in the circumferential direction around the axis C. The number of openings 636A formed is the same as the number of communication holes 513B. A partition portion 636B stands up along the axial direction on the periphery of the openings 636A.

[0086] Water sprinkling member 630 is connected to second outer cylinder member 52 on the outer circumferential surface side of first cylinder portion 631. As a result, water sprinkling member 630 rotates about axis C in response to rotation of second outer cylinder member 52. Baffle plate portion 636 is attached so as to be immovable relative to water sprinkling member 630, and therefore rotates in conjunction with the rotation of water sprinkling member 630 about axis C. As a result, the positions of multiple openings 636A formed in baffle plate portion 636 about axis C are changed.

[0087] The water sprinkling member 630 is rotatable about an axis C between a first position shown in Fig. 15 and a second position shown in Fig. 16. When the water sprinkling member 630 is in the first position, the downstream side of the communication hole 513B is covered by the baffle plate portion 636. In this state, the water spouting device 610 causes the raw water that collides with the baffle plate portion 636 to flow into the shower flow path 616A on the outer periphery side. As a result, the water spouting device 610 spouts the raw water from the raw water discharge portion 614 in a shower-like spouting form.

[0088] In the water discharger 610, when the water sprinkler member 630 is in the second position shown in FIG. 16, the positions of the multiple openings 636A in the baffle plate portion 636 around the axis C match the positions of the multiple communication holes 513B around the axis C. When the positions of the multiple openings 636A in the baffle plate portion 636 around the axis C match the positions of the multiple communication holes 513B around the axis C, the water discharger 610 can introduce the raw water spouting from the communication hole 513B into the straight flow path 615A on the downstream side through the openings 636A. That is, the raw water spouting from the communication hole 513B is guided to the straight flow path 615A by the baffle plate portion 636. As a result, the water discharger 610 discharges the raw water from the raw water discharge portion 614 in a straight water discharge form.

[0089] The water discharger 610 having the above configuration can suppress an increase in size while ensuring convenience and quality of reformed water, similar to the first embodiment. The water discharger 610 can switch between shower water discharge and straight water discharge without providing an opening / closing section or the like. Therefore, the water discharger 610 can be simplified in configuration.

[0090] The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included in the technical scope.

[0091] The modified water according to the present disclosure is not limited to the purified water exemplified in each of the above embodiments, and may be, for example, alkaline ionized water, carbonated water, or the like.

[0092] The water discharge device according to the present disclosure may be attached to the water discharge pipe so as not to be pulled out. The connection between the water discharge device and the water discharge pipe is not limited to the above-mentioned embodiments. The shape, size, etc. of the water discharge pipe to which the water discharge device is attached are not particularly limited.

[0093] The manner of the switching operation when switching the water discharge mode from the raw water discharge portion is not limited to the above-described embodiments.

[0094] It is not essential that the water discharge device includes a guide portion. [Explanation of symbols]
