[0008] <Embodiment 1> As shown in Figure 1, the washbasin vanity 1 of embodiment 1 is configured to include a washbasin cabinet 10, a holding member 60, a guide member 70, a mirror cabinet 20, a water outlet section 30, a hot and cold water mixing section 40, and a water purifier 50.

[0009] In the following description, the front-to-back direction of the bathroom vanity 1 is defined as the front when viewed from the user facing the vanity 1, and the back when viewed from the user facing the vanity 1. The left-to-right and up-to-down directions of the bathroom vanity 1 are defined as the directions as viewed from the user facing the vanity 1. The positive direction of the X axis in each diagram is the front. The positive direction of the Y axis in each diagram is the left. The positive direction of the Z axis in each diagram is the upward direction.

[0010] The washbasin cabinet 10 has a box-shaped storage section 11 that opens forward, a washbasin 13 provided at the top of the storage section 11, a standing wall 14 that rises from the rear end of the top surface of the storage section 11, and two upper and lower drawers 15 (see FIG. 2) housed in the storage section 11. The drawers 15 are not shown in FIG. 1. The storage section 11 has a pair of left and right side panels 11A, a back panel 11B, and a bottom panel 11C. A water supply pipe Wp and a hot water supply pipe Hp extend up from the floor surface F of the building frame, penetrate the bottom panel 11C, and protrude into the storage section 11. The water supply pipe Wp and the hot water supply pipe Hp are spaced a predetermined distance from the back panel 11B in the front-to-rear direction (see FIG. 2).

[0011] As shown in Figure 2, the upper and lower two drawers 15 have a decorative panel 15A that conceals the front end face of the storage section 11 and an upward-opening box section 15B for storing items. Figure 2 shows the upper drawer 15. Each drawer 15 is connected to the side panel 11A of the storage section 11 by a slide rail 15C. The rear end of the box section 15B is cut out from the center to the right end in the left-right direction, facing forward more than the left end. This ensures space within the storage section 11 for arranging a drain pipe Dp, a water supply pipe Wp, and a hot water supply pipe Hp.

[0012] The holding member 60 is formed, for example, by pressing a metal plate. The holding member 60 has a function of detachably holding the water purifier 50. As shown in FIG. 3 , the holding member 60 has a base 61 provided to stand up, a shelf portion 62 that is continuous with the lower edge of the base 61 and extends leftward in a shelf-like shape, and a rising portion 63 that stands up from the leading edge of the shelf portion 62 (the edge of the shelf portion 62 farthest from the base 61). The upper part of the base 61 is provided with a folded-back portion 64. The folded-back portion 64 is folded back in the direction (rightward) opposite to the direction (leftward) in which the shelf portion 62 extends. A through-hole 65 is formed in the base 61 and penetrates in the plate thickness direction.

[0013] A notch 66 is formed in the shelf portion 62. The notch 66 is formed so as to be recessed from the leading edge of the shelf portion 62 (the edge farthest from the base portion 61) toward the base portion 61. The rising portion 63 is located rearward of the notch 66. The holding member 60 is attached to the front portion of the right side plate 11A of the storage unit 11 (see FIG. 1). The holding member 60 is located below the upper slide rail 15C and in the vicinity of the upper slide rail 15C (see FIG. 1). The holding member 60 is fastened to the right side plate 11A by inserting a screw into the through hole 65, with the base portion 61 aligned along the right side plate 11A of the storage unit 11. When the holding member 60 is attached to the right side plate 11A of the storage unit 11, the plate thickness direction of the shelf portion 62 faces the up-down direction.

[0014] When viewing the cutout portion 66 with the holding member 60 attached to the right side plate 11A of the storage unit 11, the cutout portion 66 is formed so as to be recessed from the edge of the shelf portion 62 remote from the side plate 11A toward the side plate 11A (see FIG. 7). When viewing the rising portion 63 with the holding member 60 attached to the right side plate 11A of the storage unit 11, the rising portion 63 is formed so as to rise from the edge of the shelf portion 62 remote from the side plate 11A (see FIG. 7).

[0015] The guide member 70, like the holding member 60, is formed by pressing a metal plate. The guide member 70 is a separate component from the holding member 60. The guide member 70 has the function of detachably holding a supply hose 55 and an outflow hose 56 of the water purifier 50, which will be described later. As shown in FIG. 4 , the guide member 70 has a base portion 71 that is provided to stand up, a shelf portion 72 that is formed to be continuous with the lower edge of the base 71 and extends leftward in a shelf-like manner, and a rising portion 73 that stands up from the leading edge (left edge) of the shelf portion 72. A pair of through holes 74 is formed in the base portion 71, penetrating the plate thickness direction. The pair of through holes 74 are arranged side by side in the front-to-rear direction at the upper end of the base 71.

[0016] The base 71 and the rising portion 73 are parallel to each other and spaced a predetermined distance apart. The guide member 70 is attached to the right side plate 11A of the storage unit 11, rearward of the holding member 60 (see FIG. 1). In other words, the guide member 70 is disposed closer to the back plate 11B than the holding member 60. The guide member 70 is screwed to the side plate 11A by inserting screws into each of a pair of through holes 74, with the base 71 aligned along the right side plate 11A of the storage unit 11 (see FIG. 8). This restricts the guide member 70 from rotating relative to the right side plate 11A. When the guide member 70 is attached to the storage unit 11, the thickness direction of the shelf portion 72 faces the up-down direction.

[0017] 1, the mirror cabinet 20 is disposed above the washbasin 13. The mirror cabinet 20 is fixed to the wall W of the building frame, for example, with a fixing means such as a screw. The mirror cabinet 20 is configured to have a box-shaped cabinet main body 21 that is open toward the front, and a plurality of mirror doors 22 that are lined up in the left-right direction and close the front end of the cabinet main body 21.

[0018] The water discharge section 30 and the hot and cold water mixing section 40 are arranged side by side in the left-right direction at the upper end of the standing wall 14. Specifically, the water discharge section 30 is arranged in the center of the standing wall 14 in the left-right direction, and the hot and cold water mixing section 40 is arranged to the right of the water discharge section 30.

[0019] The water spouting unit 30 has a base unit 31, a water spouting head 32, and a pull-out hose 33. The base unit 31 is box-shaped and open upward, and is fixed to the upper end of the front surface of the standing wall 14. The water spouting head 32 is formed in a cylindrical shape and is detachably held by the base unit 31. The pull-out hose 33 is flexible. One end of the pull-out hose 33 is connected to the water spouting head 32. The other end of the pull-out hose 33 is connected to a branch socket 57 of the water purifier 50, which will be described later. The pull-out hose 33 is disposed between the standing wall 14 and the wall surface W. When the water spouting head 32 is removed from the base unit 31 and pulled out to the front, one end of the pull-out hose 33 is pulled out while still connected to the water spouting head 32. The water spouting head 32 is flexible.

[0020] The hot and cold water mixing unit 40 is configured as, for example, a disk valve incorporating a fixed disk, a movable disk, etc. As shown in Fig. 5, a water supply pipe 41, a hot water supply pipe 42, and an outflow pipe 43 are connected to the hot and cold water mixing unit 40. The user operates an operating member 45 to switch the water discharge on and off, adjust the mixing ratio of the water supplied from the water supply pipe 41 and the hot water supplied from the hot water supply pipe 42, and adjust the amount of water discharged. The water supply pipe 41, the hot water supply pipe 42, and the outflow pipe 43 are all installed between the vertical wall 14 and the wall surface W. A water supply pipe Wp is connected to the water supply pipe 41. A hot water supply pipe Hp is connected to the hot water supply pipe 42. The hot and cold water mixing unit 40 is connected downstream of the water supply pipe Wp and the hot water pipe Hp. The raw water (cold water and hot water, hereinafter simply referred to as raw water) supplied to the hot and cold water mixing section 40 through the water supply pipe 41 and the hot water supply pipe 42 is discharged to the outlet pipe 43 downstream of the hot and cold water mixing section 40. Here, the raw water is water before being purified by the water purifier 50 described later.

[0021] A socket 44 is connected to the outflow pipe 43. The socket 44 is made of, for example, synthetic resin. A flow path through which raw water flows is formed inside the socket 44. The socket 44 has a raw water inlet section 44A and a raw water outlet section 44B. The raw water inlet section 44A of the socket 44 is connected to the outflow pipe 43. The socket 44 is connected to the downstream side of the hot and cold water mixing section 40.

[0022] The water purifier 50 has a case 51, a water purification cartridge 52, an inlet portion 53, a supply hose 55, an outlet portion 54, an outlet hose 56, and a branch socket 57. The case 51 is formed to be long in one direction. The case 51 has a case main body 51A and a lid portion 51B. The case main body 51A has an accommodation space S formed therein for accommodating the water purification cartridge 52, which will be described later.

[0023] The lid 51B is detachable from the case body 51A. The lid 51B is attached to the case body 51A so as to close the storage space S. The lid 51B is provided with a switch button 51C for switching between a purification mode in which the inflowing raw water is purified and the purified water is discharged, and a non-purification mode in which the inflowing raw water is not purified and the raw water is discharged as is. The water purification cartridge 52 is cylindrical. The water purification cartridge 52 contains nonwoven fabric, activated carbon, etc. The water purification cartridge 52 is detachably housed in the storage space S of the case 51.

[0024] Inflow portion 53 is provided on the opposite side of case body 51A to lid portion 51B. Supply hose 55 is flexible and formed to be freely bendable, and one end thereof is connected to inflow portion 53. Supply hose 55 extends along the longitudinal direction of case body 51A so as to be continuous with case body 51A.

[0025] Outlet portion 54 is provided so as to protrude downward from the side surface of case body 51A. Inlet portion 53 and outlet portion 54 can be considered to be components of case 51. In other words, case 51 can be considered to have inlet portion 53 and outlet portion 54. Outlet hose 56 is flexible and formed to be freely bendable, and one end thereof is connected to outlet portion 54. Outlet hose 56 extends along the longitudinal direction of case body 51A and is arranged parallel to supply hose 55.

[0026] The branch socket 57 is made of, for example, synthetic resin. As shown in FIG. 6, the branch socket 57 has a raw water flow path F1 through which raw water flows and a purified water flow path F2 through which purified water flows. The raw water flow path F1 and the purified water flow path F2 are formed separately and do not intersect. The branch socket 57 has a raw water inlet 57A, a raw water outlet 57B, a purified water inlet 57C, and a purified water outlet 57D. The raw water inlet 57A and the raw water outlet 57B are connected by the raw water flow path F1. The purified water inlet 57C and the purified water outlet 57D are connected by the purified water flow path F2.

[0027] As shown in Figure 5, the raw water inlet 57A is connected to the raw water outlet 44B of the socket 44. The branch socket 57 is connected to the downstream side of the socket 44. The raw water outlet 57B is connected to the other end of the supply hose 55. The purified water inlet 57C is connected to the other end of the outlet hose 56. The purified water outlet 57D is connected to the other end of the draw-out hose 33 of the water discharger 30.

[0028] [Flow of raw water and purified water in the water circuit of a bathroom vanity] The raw water, ie, hot water and cold water, supplied from the water supply pipe Wp and the hot water supply pipe Hp flow into the hot water / water mixer 40 via the water supply piping 41 and the hot water supply piping 42. In the hot water / water mixer 40, the raw water and hot water are mixed and flow into the branch socket 57 of the water purifier 50 via the outlet piping 43 and the socket 44. In other words, the water purifier 50 is connected downstream of the hot water / water mixer 40. The raw water that flows into the branch socket 57 flows into the case 51 of the water purifier 50 via the raw water flow path F1 (see FIG. 6), the supply hose 55, and the inlet 53. In other words, the raw water flows into the inlet 53 from the hot water / water mixer 40. In addition, the supply hose 55 supplies the raw water to the case 51 of the water purifier 50.

[0029] In case 51, raw water is purified by water purification cartridge 52 to become purified water. The purified water then flows into drawer hose 33 via outlet 54, outflow hose 56, and purified water flow path F2 of branch socket 57. That is, purified water flows out of outlet 54. Also, purified water flowing out of case 51 of water purifier 50 flows through outflow hose 56. The purified water is then discharged from water discharge head 32 of water discharge unit 30 and reaches washbasin 13. That is, water discharge unit 30 discharges purified water purified by water purifier 50 into washbasin 13.

[0030] [Installing the water purifier in the storage compartment] First, as shown in FIG. 7 , the case 51 of the water purifier 50 is placed on the holding member 60 attached to the side plate 11A of the storage unit 11. Specifically, the case 51 is placed on the shelf portion 62 of the holding member 60 with the outlet portion 54 facing downward and the supply hose 55 and the outlet hose 56 extending rearward. This allows the water purifier 50 to be detachably attached and held on the side plate 11A. At this time, the outlet portion 54 is inserted from the left into the notch portion 66 of the holding member 60 and fitted. Then, the case 51 is placed on the upper surface of the shelf portion 62 while being positioned to the right of the rising portion 63. The cutout portion 66 restricts the movement of the outlet portion 54 in the front-to-rear direction, and the case 51 is restricted from moving left and right by fitting between the base portion 61 and the rising portion 63. The case 51 of the water purifier 50 is attached near the front of the side plate 11A (see FIGS. 1 and 8 ).

[0031] Next, as shown in FIG. 8 , the supply hose 55 and the outflow hose 56 are fitted into the guide member 70 from above and locked. The dimension between the base 71 and the rising portion 73 of the guide member 70 is slightly larger than the outer diameters of the supply hose 55 and the outflow hose 56. This allows the supply hose 55 and the outflow hose 56 to be easily attached to and detached from the guide member 70. For example, the rising dimension of the rising portion 73 is set to be larger than the sum of the outer diameters of the supply hose 55 and the outflow hose 56. This allows the supply hose 55 and the outflow hose 56 to be securely locked to the guide member 70 and are less likely to fall off the guide member 70. The guide member 70 guides the supply hose 55 and the outflow hose 56 along the side panel 11A toward the back panel 11B.

[0032] Next, the supply hose 55 and the outflow hose 56 are arranged to pass between the water supply pipe Wp and the hot water pipe Hp and the front surface of the back panel 11B of the storage section 11. This prevents the supply hose 55 and the outflow hose 56 from coming into contact with the rear end of the drawer 15. In this manner, the water purifier 50 is housed in the storage section 11 of the bathroom cabinet 10. When the water purifier 50 is housed in the storage section 11, the guide member 70 is attached to the side panel 11A closer to the back panel 11B than the water purifier 50. When the water purifier 50 is housed in the storage section 11, the water purifier 50 is located to the right of the hot and cold water mixing section 40, and the water discharge section 30 is located to the left of the hot and cold water mixing section 40 (see FIG. 1).

[0033] Next, the operation of the first embodiment will be described.

[0034] The bathroom vanity 1 includes a wash cabinet 10 with a wash bowl 13 provided on top, a water purifier 50 housed in the wash cabinet 10, and a water discharge part 30 that discharges purified water purified by the water purifier 50 into the wash bowl 13.

[0035] According to this configuration, purified water can be discharged from the water discharger 30, and the purified water can be used when washing hands, face, etc.

[0036] The bathroom vanity 1 further includes a hot and cold water mixing section 40, and the water purifier 50 is connected downstream of the hot and cold water mixing section 40. With this configuration, instead of only the water supplied from the water supply pipe Wp passing through the water purifier 50, mixed water obtained by mixing the water supplied from the water supply pipe Wp and the hot water supplied from the hot water supply pipe Hp by the hot and cold water mixing section 40 passes through the water purifier 50, so that purified water at the temperature desired by the user can be discharged from the water discharge section 30.

[0037] The washbasin cabinet 10 has a pair of left and right side plates 11A, and the water purifier 50 is detachably attached to the right side plate 11A. This configuration makes it easy to replace the water purification cartridge 52, and also makes it possible to effectively use the available space in the washbasin cabinet 10 as space for placing the water purifier 50.

[0038] The bathroom vanity 1 further includes a holding member 60 that is attached to the right side panel 11A of the bathroom cabinet 10 and detachably holds the water purifier 50. With this configuration, the water purifier 50 can be easily attached to and detached from the side panel 11A.

[0039] The holding member 60 has a shelf-like portion 62 on which the water purifier 50 is placed, and the shelf portion 62 has a notch 66 formed therein into which a portion of the water purifier 50 fits. With this configuration, the water purifier 50 can be attached to the side plate 11A simply by placing the water purifier 50 on the shelf portion 62. In addition, fitting a portion of the water purifier 50 (outlet portion 54) into the notch 66 makes it possible to determine the attachment position of the water purifier 50.

[0040] The cutout portion 66 is formed so as to be recessed from the edge of the washbasin cabinet 10 farthest from the right side plate 11A toward this side plate 11A. With this configuration, a part of the water purifier 50 (the outflow portion 54) can be fitted into the cutout portion 66 without interfering with the work of attaching the water purifier 50 to the holding member 60.

[0041] The water purifier 50 has an inlet portion 53 into which raw water flows from the hot and cold water mixing portion 40, and an outlet portion 54 from which purified water flows out, and the outlet portion 54 fits into the cutout portion 66. With this configuration, the outlet portion 54 fits into the cutout portion 66, thereby restricting the movement of the water purifier 50 in the front-to-rear direction relative to the holding member 60.

[0042] The holding member 60 has a rising portion 63 that rises from the left edge of the shelf portion 62, away from the right side panel 11A of the washbasin cabinet 10. With this configuration, the rising portion 63 can restrict left-right movement of the water purifier 50 relative to the holding member 60.

[0043] The water purifier 50 has a case 51 having an inlet 53 through which raw water flows in and an outlet 54 through which purified water flows out, and a water purification cartridge 52 that is detachably housed in the case 51. With this configuration, the water purification cartridge 52 can be replaced without the need to detach the supply hose 55 extending upstream of the inlet 53 of the case 51 or the outlet hose 56 extending downstream of the outlet 54 of the case 51, making replacement of the water purification cartridge 52 easy.
