Description

[Technical field]

[0001] The disclosed embodiment relates to a water discharge device. [Background technology]

[0002] Conventionally, there is known a water discharge device that is installed on a wall surface in, for example, a toilet room (see, for example, Patent Document 1). In such a water discharge device, a technology is also known in which a water supply pipe that supplies water to the water discharge part is provided and housed on the front side of the wall surface, thereby eliminating the need for water supply work on the back side of the wall surface, thereby improving workability (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-029124 A [Patent Document 2] JP 2002-345662 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the water discharge device described above, it is desirable to make it compact by reducing the depth in the front-to-rear direction. Therefore, for example, it is conceivable to make it compact by reducing the depth of the storage space in which the water supply pipe is stored.

[0005] However, there is a limit to how narrow the depth can be, and it is difficult to make it thinner than the water supply pipe it is housed in. In addition, one possible way to make it thinner is to thin the back part (back guard part) of the hand washing basin, but this would reduce the strength of the back part. Thus, the conventional technology has room for further improvement in terms of making the depth of the water discharge device thinner and more compact.

[0006] One aspect of the embodiment aims to provide a water discharge device that can be made compact by reducing the depth in the front-to-rear direction. [Means for solving the problem]

[0007] A water discharge device according to one embodiment comprises a water discharge section, a water supply section which supplies water to the water discharge section, and a panel section which is installed opposite an installation surface, wherein a storage space which accommodates at least a part of the water supply section is formed between the panel section and the installation surface, wherein the water supply section is arranged within the storage space and includes a plurality of second water supply passages which are connected to the downstream side of a first water supply passage which is connected to a water supply source, and a junction section which is connected to the downstream side of the plurality of second water supply passages and which joins water from the plurality of second water supply passages, wherein each of the plurality of second water supply passages is formed so that its outer dimensions are smaller than the outer dimensions of the first water supply passage and is flexible, and wherein the junction section is accommodated in the storage space and formed integrally with the water discharge section.

[0008] This allows the depth of the storage space to be smaller and thinner than when, for example, a water supply pipe is stored, and therefore the water discharge device can be made thinner and more compact. In addition, by providing a plurality of water supply passages in the water supply section with outer dimensions smaller than the water supply pipe, it is possible to discharge water from the water discharge section while maintaining the amount of water supplied from the water supply pipe. In addition, by providing the plurality of water supply passages with flexibility, the water supply passages can be easily handled during construction and maintenance, and deterioration of construction and maintenance can be suppressed, thereby further improving construction and the like.

[0009] The second water supply passages are arranged side by side in the left-right direction.

[0010] This allows the depth of the storage space to be reduced, making it thinner, and the water discharge device to be more compact.

[0011] The water supply section is further characterized in that it includes a junction section connected to the downstream side of the multiple second water supply passages and junctions the waters of the multiple second water supply passages, and the junction section is accommodated in the accommodation space.

[0012] This makes it possible to prevent kinking in the water supply passage. In other words, since the water supply passage has flexibility, kinking such as bending or twisting is more likely to occur compared to when the water supply passage is made of a material with high rigidity. Therefore, by accommodating the junction in the accommodation space as described above, it is possible to prevent, for example, the water supply passage from being bent midway and connected to the junction, and therefore it is possible to prevent kinking in the water supply passage.

[0013] The second water supply passages are arranged to extend vertically within the storage space up to a connection position with the junction.

[0014] This makes it difficult for unnecessary loads to be placed on the water supply passage, thereby effectively preventing kinking.

[0015] The confluence portion is formed integrally with the water discharge portion.

[0016] This allows the number of parts to be reduced compared to, for example, a case in which the junction section and the water discharge section are separate, making it possible to make the water discharge device more compact.

[0017] The device also includes a mounting portion provided below the water receiving portion that receives water from the water outlet portion, on which the water receiving portion is placed, and the mounting portion has insertion holes through which multiple second water supply passages are inserted.

[0018] This can further improve the ease of installation of the water discharge device. That is, for example, when placing the hand-washing basin on a counter, the worker inserts the flexible water supply passage into the insertion hole while tilting the panel part forward, and then raises the panel part and installs it on the wall surface (installation surface), thereby making it possible to place the hand-washing basin on the counter. This makes it less likely that the wall surface will be damaged by the panel part, for example, and can further improve the ease of installation of the water discharge device.

[0019] The water supply section is further characterized in that it includes a diversion section connected between the first water supply passage and the multiple second water supply passages, which diverts water from the first water supply passage to the multiple second water supply passages, and the diversion section is positioned so that its connection position with the multiple second water supply passages is lower than the lower end of the insertion hole.

[0020] As a result, multiple water supply lines are accommodated in the accommodation space, and multiple water supply lines are inserted into all of the counter's insertion holes. In other words, no diverter is arranged in the accommodation space or the counter's insertion holes. Therefore, the depth of the accommodation space can be made smaller and thinner than when, for example, a water supply pipe and a diverter are configured to be accommodated, and the depth of the water discharge device can be made thinner and more compact.

[0021] The water supply device is also characterized by comprising a holding portion for holding a plurality of the second water supply passages.

[0022] This makes it possible to prevent, for example, the multiple water supply channels from coming apart during construction, which would reduce workability. Also, by providing the retaining portion, it is possible to prevent, for example, the water supply channels from being subjected to unintended force during construction, which would cause kinking or the like in the water supply channels.

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a water discharger disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiment described below.

[0026] (First embodiment) Fig. 1 is an overall perspective view showing a water discharge device according to a first embodiment. Note that Fig. 1 and the figures shown in Fig. 2 and subsequent figures are all schematic diagrams.

[0027] For ease of explanation, FIG. 1 illustrates a three-dimensional Cartesian coordinate system that defines mutually orthogonal X-axis, Y-axis, and Z-axis directions, and defines the positive Z-axis direction as the vertical upward direction. Such Cartesian coordinate systems may also be shown in other drawings used in the following explanation. In addition, in the following explanation, for example, based on the state when the water discharge device 1 is installed, the positive X-axis direction in the Cartesian coordinate system may be described as "right", the negative X-axis direction as "left", the positive Y-axis direction as "forward" or "front side", the negative Y-axis direction as "rear" or "rear side", the positive Z-axis direction as "upward", and the negative Z-axis direction as "downward".

[0028] As shown in Fig. 1, the water discharger 1 is a wall-mounted type and is installed on a wall surface W. The water discharger 1 is, for example, a hand-washing device installed on a wall surface W in a toilet room, but is not limited to this. That is, the water discharger 1 may be installed on a wall surface in other places, such as a washroom or a kitchen. The wall surface W is an example of an installation surface.

[0029] Fig. 2 is a front view of the water discharger 1, and Fig. 3 is a rear view of the water discharger 1. As shown in Figs. 1 to 3, the water discharger 1 includes a hand-washing basin 10, a counter 20, a water discharger 30 (not visible in Fig. 3), a water supply unit 40 (not visible in Fig. 1), and a holder 60 (not visible in Fig. 1).

[0030] In Fig. 2, for ease of understanding, the hand washing basin 10 and the counter 20 are shown by imaginary lines so that the water supply unit 40 located on the rear side of the hand washing basin 10, etc. can be seen. Also, in Fig. 3, the counter 20 is shown by imaginary lines.

[0031] The hand-washing basin 10 comprises a water receiving portion 11 and a panel portion 12. The water receiving portion 11 is formed, for example, in a bowl shape, and receives water discharged from the water discharge portion 30. The water receiving portion 11 drains the received water from a drain hole 13 (see FIG. 3 and FIG. 4 described later) to a drain pipe 14 (see FIG. 3) indicated by a two-dot chain line. Note that the expression "water" is sometimes used to mean water at room temperature such as clean water (tap water), as well as hot water, a mixture of hot and cold water, cold water, etc.

[0032] The panel portion 12 is formed, for example, in a flat plate shape, and is located on the back side (rear side; Y-axis negative side) of the water receiving portion 11. That is, the panel portion 12 is also a wall portion on the back side of the water receiving portion 11. Specifically, the panel portion 12 includes a back wall portion 12a, an upper wall portion 12b, and two side wall portions 12c.

[0033] The rear wall portion 12a is a flat plate-like portion formed to stand upright in the vertical direction. A water discharge portion 30 is provided on the rear wall portion 12a of the panel portion 12. The upper wall portion 12b is formed to extend rearward (Y-axis negative direction) from the upper end of the rear wall portion 12a. The side wall portions 12c are formed to extend rearward (Y-axis negative direction) from the left and right side ends of the rear wall portion 12a.

[0034] The panel unit 12 configured as described above is installed (fixed) so as to face the installation surface, which is the wall surface W. More specifically, the panel unit 12 is installed with the rear wall portion 12a disposed so as to face the wall surface W. Thus, in the panel unit 12, a space is formed that is surrounded by the rear wall portion 12a, the upper wall portion 12b, the two side wall portions 12c, and the wall surface W, and this space functions as a storage space 50 that stores a part of the water supply unit 40, which will be described later.

[0035] The counter 20 is, for example, a plate-shaped member, and is provided below the water receiving portion 11. The counter 20 is fixed to, for example, a wall surface W or a floor surface (not shown).

[0036] The counter 20 is an example of the mounting part. In the above, the counter 20 is taken as an example of the mounting part, but the present invention is not limited to this, and the mounting part may be, for example, a cabinet top plate (counter) or other objects capable of mounting the water receiving part 11. The counter 20 is also formed with an insertion hole 21 (see FIG. 6) through which a part of the water supply part 40 is inserted, which will be described later.

[0037] The water discharger 30 discharges water toward the hand-washing basin 10. The detailed configuration of the water discharger 30 will be described later with reference to FIG.

[0038] Water supply unit 40 is connected to water discharge unit 30 and supplies water to water discharge unit 30. Here, water supply unit 40, storage space 50, etc. will be described with reference to Figs. 4 to 6.

[0039] Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2. Fig. 5 is a partially enlarged cross-sectional view of Fig. 4, more specifically, an enlarged cross-sectional view of a portion surrounded by a dashed line in Fig. 4. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 2.

[0040] 4 to 6, the storage space 50 is formed between the panel portion 12 and the wall surface W. Specifically, the storage space 50 is a space surrounded by the rear wall portion 12a, the upper wall portion 12b, the two side wall portions 12c of the panel portion 12, and the wall surface W, as described above.

[0041] A part of the water supply unit 40 is provided and accommodated in such accommodation space 50. That is, in this embodiment, since the water supply unit 40 is provided on the front side of the wall W, it is possible to eliminate the need for water supply construction on the back side of the wall W, for example. This makes it possible to install the water discharger 1 in a relatively short period of time and at low cost, and improves the ease of construction of the water discharger 1.

[0042] Also, in this embodiment, the depth D (see FIG. 6) of the accommodation space 50 is made as small as possible to make it thin, thereby making the water discharger 1 compact.

[0043] 2 and 3, the water supply section 40 includes a water supply pipe 41, a water supply passage 42, a branch section 43, and a junction section 44. The water supply pipe 41 is an example of a first water supply passage, and the water supply passage 42 is an example of a second water supply passage.

[0044] The water supply pipe 41 is connected to a water supply source such as a water pipe (not shown) via a stop valve 100 (shown as a block in FIG. 2) provided on the wall surface W. A solenoid valve 101 for an automatic water faucet is connected between the water supply pipe 41 and the stop valve 100. The solenoid valve 101 opens to open the flow path while a detection signal indicating that, for example, a user's hand is placed near the water discharge unit 30 is being output from a human body detection sensor (not shown), and closes to block the flow path when the output of the detection signal stops. That is, the water discharge device 1 is equipped with an automatic water faucet that automatically discharges water when, for example, a user places his or her hand out. The water supply pipe 41 is made of a flexible material (for example, a resin such as silicone), but the material is not limited thereto.

[0045] There are a plurality (for example, three (three pipes)) of water supply paths 42, which are connected to the downstream side of the water supply pipe 41 via a flow dividing portion 43. Further, a water discharge portion 30 is connected to the downstream side of the water supply path 42 via a confluence portion 44. Note that in the above description, the number of water supply paths 42 is three, but it is not limited thereto, and for example, there may be two or four or more.

[0046] As described above, it is assumed that water supplied from the same water supply pipe 41 flows through the plurality of water supply paths 42. In other words, it is assumed that water supplied from the same water supply system flows through the plurality of water supply paths 42, but it is not limited thereto.

[0047] Each of the plurality of water supply paths 42 is formed to be thinner than the upstream water supply pipe 41. Specifically, as shown in FIG. 6, each of the plurality of water supply paths 42 is formed such that the outer dimension (outer diameter) E2 is smaller than the outer dimension (outer diameter) E1 of the water supply pipe 41 (E2 < E1). Here, the outer dimension E2 of the water supply path 42 is set to a value such that, for example, the total flow rate of the water flowing through the plurality of water supply paths 42 is the same as or equivalent to the flow rate of the water flowing through the upstream water supply pipe 41. Note that all of the plurality of water supply paths 42 are set to the same outer dimension E2, but it is not limited thereto, and a part or all of the plurality of water supply paths 42 may be set to have different outer dimensions from each other.

[0048] Then, as shown in FIGS. 5 and 6, the plurality of water supply paths 42 configured as described above are arranged in the accommodation space 50. Thereby, the depth D (see FIG. 6) of the accommodation space 50 can be made smaller and thinner than, for example, the case where the water supply pipe 41 is configured to be accommodated, and thus the depth of the water discharge device 1 can be made thinner and the device can be made more compact.

[0049] Further, in the water supply portion 40 according to the present embodiment, by providing a plurality (here, three) of water supply paths 42 having an outer dimension E2 smaller than that of the water supply pipe 41, it is possible to discharge water from the water discharge portion 30 while maintaining the amount of water supplied from the water supply pipe 41.

[0050] Furthermore, the multiple water supply channels 42 are arranged side by side in the left-right direction (X-axis direction) as shown in Fig. 5 etc. This allows the depth D (see Fig. 6) of the accommodation space 50 to be made smaller and thinner, and the water discharger 1 can be made more compact.

[0051] Here, as described above, if multiple water supply lines 42 are provided and the water supply lines 42 are made of a highly rigid material such as copper pipes, it may become difficult to handle the water supply lines 42, for example, when connecting the water supply lines 42 during construction or removing the water supply lines 42 during maintenance, which may result in a decrease in workability and maintainability.

[0052] Therefore, each of the water supply passages 42 according to the present embodiment is configured to have flexibility. Note that, as the water supply passages 42, for example, a tube made of resin (such as polyvinyl chloride or silicone) can be used, but the present invention is not limited thereto.

[0053] In this way, by having the multiple water supply passages 42 be flexible, the water supply passages 42 become easier to handle during construction and maintenance, and deterioration in construction and maintenance can be suppressed, thereby further improving construction ease, etc.

[0054] The diverter 43 is connected between the water supply pipe 41 and the multiple water supply passages 42. The diverter 43 distributes water from the water supply pipe 41 to the multiple water supply passages 42. For example, as shown in FIG. 6, the diverter 43 is inserted and positioned so that a portion of the diverter 43 is positioned in the insertion hole 21 of the counter 20. The diverter 43 is positioned so that a connection position 43x with the upstream water supply pipe 41 is lower than the lower end 21a of the insertion hole 21, while a connection position 43y with the downstream water supply passage 42 is higher than the upper end 21b of the insertion hole 21. The position at which the diverter 43 is positioned is merely an example and is not limited to the above.

[0055] Here, as described above, if the water is divided into multiple water supply channels 42 at the dividing section 43, and then, as described below, the divided multiple water supply channels 42 are merged at the merging section 44, there is a risk that the water discharged from the water discharge section 30 will be disturbed. That is, if configured as described above, for example, water will not flow evenly in each water supply channel 42, and the speed of water flowing in each water supply channel 42 is likely to differ from one another, which may cause the flow of water to be disturbed in the water supply section 40 including the water supply channels 42 at the time of division or merging, and therefore the water discharged from the water discharge section 30 may be disturbed.

[0056] Therefore, in the present embodiment, the branching section 43, the merging section 44, and the like are configured to be able to suppress turbulence in the discharged water from the water discharger 30.

[0057] First, the flow dividing section 43 will be described in detail with reference to Figs. 7 to 9. Fig. 7 is a front view of the flow dividing section 43, and Fig. 8 is a plan view (top view) of the flow dividing section 43. Fig. 9 is a cross-sectional view taken along line IX-IX in Fig. 7. For ease of understanding, in Figs. 7 to 9, the water supply pipe 41 and the water supply channel 42 connected to the flow dividing section 43 are shown by imaginary lines.

[0058] 7 to 9, the flow dividing section 43 includes an inflow section 43a, an outflow section 43b, and a flow straightening section 43c. The inflow section 43a is a section into which water flows from the water supply pipe 41. For example, the inflow section 43a is formed with an inlet 43a1. The water supply pipe 41 is connected to the inlet 43a1, and the water from the water supply pipe 41 flows in.

[0059] Outlet portions 43b are portions through which water flows out to water supply passage 42, and there are a plurality of outlet portions 43b. Since there are corresponding outlet portions 43b to water supply passage 42, there are the same number of outlet portions 43b as there are water supply passages 42 (here, three). For example, each of the plurality of outlet portions 43b is formed with an outlet 43b1. Water supply passage 42 is connected to the outlets 43b1, and water flows out to water supply passage 42.

[0060] Straightening section 43c straightens the water flowing through water supply section 40, more specifically, straightens the water flowing from water supply pipe 41 to water supply passage 42 via flow dividing section 43. By straightening the water in such a manner, for example, water flows evenly through each water supply passage 42, and the speed of the water flowing through each water supply passage 42 tends to be the same or equivalent. This makes it difficult for the water flow to become turbulent when the water is divided or merged, and therefore makes it possible to suppress turbulence in the water discharged from water discharge section 30.

[0061] The flow straightening portion 43c will be described in detail below. For example, the flow straightening portion 43c is a portion provided between the inflow portion 43a and the outflow portion 43b. The flow straightening portion 43c is formed to be hollow, and as shown in FIG. 9, is formed to be L-shaped in side view.

[0062] For example, the flow straightening section 43c includes a first flow path 43c1, a second flow path 43c2, and a collision wall section 43c3. The first flow path 43c1 is formed so that the upstream side communicates with the inflow section 43a and the downstream side communicates with the second flow path 43c2. Also, as shown in FIG. 8, the first flow path 43c1 is formed so that it widens in the left-right direction (X-axis direction) as it approaches the second flow path 43c2, in other words, as it moves downstream.

[0063] The second flow passage 43c2 is formed so that the upstream side thereof communicates with the first flow passage 43c1 and the downstream side thereof communicates with the multiple (here, three) outlet portions 43b. The second flow passage 43c2 is formed so as to extend along the up-down direction.

[0064] 9, the collision wall portion 43c3 is formed at a position facing the inlet 43a1 of the inflow portion 43a on the upper end side (ceiling side) of the first flow path 43c1. Here, since the water flowing in from the inlet 43a1 of the inflow portion 43a flows from below to above, the water flowing in from the inlet 43a1 (in other words, the water flowing from upstream) collides with the collision wall portion 43c3 (see arrow G1).

[0065] As shown by arrow G2, the water that collides with the collision wall portion 43c3 flows into the second flow path 43c2, and then branches (diverges) into the multiple outlet portions 43b and flows into the corresponding water supply paths 42. In this manner, in the rectification portion 43c, the water from the water supply pipe 41 collides with the collision wall portion 43c3 and is rectified, and the rectified water is diverted and flows into the multiple water supply paths 42 via the second flow path 43c2 and the outlet portion 43b.

[0066] As a result, the water speed, etc. of each water supply passage 42 becomes the same or equivalent, so that the water flow is less likely to be disturbed when the water branches or merges, and disturbance of the water discharge can be suppressed, as already mentioned.

[0067] In addition, the straightening section 43c is provided with a collision wall section 43c3 against which the water from the water supply pipe 41 collides, so that the water flowing from the water supply pipe 41 to the water supply passage 42 via the branch section 43 can be straightened with a simple configuration.

[0068] Here, the positional relationship of the outlet 43b1 to the inlet 43a1 in the flow dividing section 43 will be described in detail with reference to Fig. 8. The outlet 43b1 of the flow dividing section 43 is positioned so as to be shifted from the inlet 43a1 in a plan view, in other words, when viewed from the up-down direction parallel to the water flow direction.

[0069] Specifically, the flow dividing section 43 is formed such that a central axis B1 of the flow passage cross section at the plurality of outlets 43b1 is eccentric (displaced) from a central axis A1 of the flow passage cross section at the inlet 43a1.

[0070] To state the above in another way using the water supply passage 42 connected to the outlet 43b1 and the water supply pipe 41 connected to the inlet 43a1, the central axis (same position as the above-mentioned central axis B1) of the flow path cross section at the upstream end of all water supply passages 42 provided downstream of the diversion section 43 is positioned so as to be eccentric (displaced) from the central axis (same position as the above-mentioned central axis A1) of the flow path cross section at the downstream end of the water supply pipe 41 provided upstream of the diversion section 43.

[0071] This allows water to flow more evenly from the diverter 43 to each water supply passage 42. In other words, if the central axis B1 of some of the outlets 43b1 among the multiple outlets 43b1 is coaxial with the central axis A1 of the inlet 43a1, water from the inlet 43a1 will flow more easily to the some of the outlets 43b1. As a result, the water flow will be biased to the water supply passage 42 connected to some of the outlets 43b1, and water will not flow evenly to each water supply passage 42, which may cause the water discharge from the water discharger 30 to be disturbed as described above.

[0072] In the diversion section 43 of this embodiment, the central axis B1 of the multiple outlets 43b1 is configured to be eccentric with respect to the central axis A1 of the inlet 43a1, making it possible for water to flow more evenly from the diversion section 43 to each water supply passage 42, thereby effectively suppressing turbulence in the water discharge.

[0073] Further, the outlet 43b1 is formed at a position that does not overlap with the inlet 43a1 when viewed from the central axis B1 direction of the flow path cross section at the outlet 43b1. More specifically, the outlets 43b1 are formed so that the inlet 43a1 is not positioned within a projection plane of the outlet 43b1 projected in the central axis B1 direction (in other words, the vertical direction parallel to the water flow direction).

[0074] This makes it possible, for example, to more evenly flow water from the diverter 43 to each water supply passage 42. In other words, if some of the multiple outlets 43b1 are located at positions overlapping with the inlets 43a1 when viewed from the direction of the central axis B1, water from the inlets 43a1 may easily flow to those outlets 43b1, which may result in water not flowing evenly to each water supply passage 42.

[0075] In this embodiment, the outlet 43b1 is formed at a position that does not overlap with the inlet 43a1 when viewed from the direction of the central axis B1, making it possible for water to flow more evenly from the branch section 43 to each water supply passage 42, and as a result, turbulence in the water discharge can be more effectively suppressed.

[0076] Next, a description will be given of the junction 44. As shown in Figures 2, 6, etc., the junction 44 is connected to the downstream side of the multiple water supply passages 42. The junction 44 merges the waters of the multiple water supply passages 42.

[0077] 6, the junction 44 is accommodated in a storage space 50. More specifically, the junction 44 is accommodated in the storage space 50 together with the water supply passage 42. In other words, the junction 44 is accommodated in the same storage space 50 as the water supply passage 42.

[0078] This can prevent kinking from occurring in the water supply passage 42. In other words, since the water supply passage 42 is flexible, kinking such as bending or twisting is more likely to occur than when the water supply passage 42 is made of a material with high rigidity. Therefore, in this embodiment, since the junction 44 is accommodated in the accommodation space 50, it is possible to prevent, for example, the water supply passage 42 from being bent midway and connected to the junction 44, and therefore it is possible to prevent kinking from occurring in the water supply passage 42.

[0079] The water supply passages 42 are arranged to extend vertically within the accommodation space 50 to a connection position 44x with the junction 44. More specifically, the water supply passages 42 are arranged to extend linearly vertically within the accommodation space 50 from a connection position 43y with the upstream branch section 43 to a connection position 44x with the downstream junction 44.

[0080] This makes it difficult for unnecessary load to be placed on the water supply passage 42, thereby effectively preventing kinking.

[0081] Next, the configuration of the junction 44 that can suppress turbulence in the discharged water will be described in detail with reference to Figs. 10 to 12. Fig. 10 is a front view of the junction 44, and Fig. 11 is a side view of the junction 44. Fig. 12 is a cross-sectional view taken along line XII-XII in Fig. 10. For ease of understanding, in Figs. 10 to 12, the water supply passage 42 connected to the junction 44 is shown by imaginary lines.

[0082] As shown in Figs. 10 to 12, the junction 44 includes an inlet 44a, an outlet 44b (shown only in Fig. 12), and a flow straightening section 44c. The inlet 44a is a portion into which water flows from the multiple water supply channels 42, and there are multiple inlet sections 44a. Since the inlet sections 44a correspond to the water supply channels 42, there are the same number of inlet sections 44a as the water supply channels 42 (here, three). For example, each of the multiple inlet sections 44a is formed with an inlet 44a1. The water supply channels 42 are connected to the multiple inlet sections 44a1, and the water from the water supply channels 42 flows in.

[0083] As shown in Fig. 12, the outflow section 44b is a section that discharges water to the water discharger 30. For example, an outlet 44b1 is formed in the outflow section 44b. The outlet 44b1 is connected to the water discharge port 31 (see Fig. 10) of the water discharger 30, and discharges water to the water discharge port 31.

[0084] Before describing the flow straightening section 44c, the water discharge section 30 will be described. As shown in FIG. 10, the water discharge section 30 receives water that has been joined at the joining section 44 and discharges it from the water discharge port 31. The water discharge port 31 is formed to be wide in the left-right direction (X-axis direction). Therefore, water is discharged from the water discharge port 31 in the shape of a wide waterfall (in other words, a thin film). Note that the outlet 44b1 of the outflow section 44b corresponds to the water discharge port 31, and is therefore formed to be wide in the left-right direction, similar to the water discharge port 31 (see FIG. 12).

[0085] In this embodiment, the junction 44 and the water discharger 30 are integrally formed. In this manner, the junction 44, which is a part of the water supply section 40, and the water discharger 30 are integrally formed, so the number of parts can be reduced compared to when the junction 44 and the water discharger 30 are separate, and the water discharger 1 can be made more compact.

[0086] In the above, the confluence portion 44 and the water discharge portion 30 are formed integrally, but this is not limited to this, and for example, the confluence portion 44 and the water discharge portion 30 may be formed separately.

[0087] Returning to the explanation of rectifier 44c, rectifier 44c rectifies the water flowing in water supply unit 40, more specifically, rectifies the water flowing from water supply passage 42 to water discharge unit 30 via junction 44. Such rectification by rectifier 44c causes water to flow evenly in each water supply passage 42 and flow path 44c1 (see FIG. 12) of junction 44, and the speed of water flowing in each water supply passage 42 tends to be the same or equivalent. This makes it difficult for the water flow to become turbulent when the water is divided or merged, thereby making it possible to suppress turbulence in the water discharged from water discharge unit 30.

[0088] The flow straightening portion 44c will be described in detail below. For example, the flow straightening portion 44c is a portion provided between the inflow portion 44a and the outflow portion 44b. The flow straightening portion 44c is formed to be hollow and to extend in the up-down direction.

[0089] For example, as shown in Fig. 12, the flow straightening section 44c includes a flow path 44c1, a collision wall section 44c2, and a guide section 44c3. The flow path 44c1 communicates with the inflow section 44a (more specifically, the inlet 44a1) on the upstream side. This allows water from the multiple water supply passages 42 to flow into the flow path 44c1 via the inflow section 44a and merge.

[0090] The flow path 44c1 is formed so that the downstream side is in communication with the outflow portion 44b (more specifically, the outflow port 44b1). The flow path 44c1 is formed so that the width of the flow path 44c1 increases in the left-right direction (X-axis direction) as it approaches the outflow portion 44b, in other words, as it moves downstream.

[0091] The collision wall portion 44c2 is formed in the flow path 44c1 at a position facing the inlet 44a1 of the inflow portion 44a. There are a plurality of collision wall portions 44c2. Since the collision wall portions 44c2 correspond to the inlet 44a1, there are the same number of collision wall portions 44c2 as the inlet 44a1 (here, three). The collision wall portion 44c2 is, for example, a cylindrical boss erected in the flow path 44c1, but is not limited thereto and may be a wall portion of another shape, such as a plate shape.

[0092] The guide portion 44c3 is formed in the flow path 44c1 on the downstream side of the collision wall portion 44c2, and guides the water in the flow path 44c1 to the outlet 44b1. For example, the guide portion 44c3 is formed to extend radially toward the downstream side from the collision wall portion 44c2 located near the center of the flow path 44c1.

[0093] Here, the water flowing from the inlet 44a1 of the inflow section 44a into the flow path 44c1 of the flow straightening section 44c flows from the bottom to the top, so that the water that has flowed into the flow path 44c1 from the inlet 44a1 (in other words, the water flowing from upstream) collides with the collision wall section 44c2 (see arrow H1).

[0094] The water that collides with the collision wall portion 44c2 spreads radially by the guide portion 44c3 as shown by the arrow H2, and flows and is discharged through the outlet 44b1 of the outflow portion 44b to the water discharge portion 30. In this way, in the rectification portion 44c, the water from the multiple water supply passages 42 collides with the collision wall portion 44c2 and is rectified, and the rectified water is discharged from the water discharge portion 30 through the outflow portion 44b.

[0095] As a result, water flows evenly in each water supply passage 42 and flow path 44c1, and the speed of the water flowing in each water supply passage 42 tends to be the same or equivalent, so that the water flow is less likely to be disturbed when the water branches or merges, and turbulence in the water discharge can be suppressed, as already mentioned.

[0096] In addition, the straightening section 44c is provided with a collision wall section 44c2 against which water from the water supply passage 42 collides, so that the water flowing from the water supply passage 42 through the junction section 44 to the water discharge section 30 can be straightened with a simple configuration.

[0097] Here, the multiple water supply passages 42 connected to the junction 44 configured as described above are formed to have the same length. This makes it possible to further suppress turbulence in the discharged water.

[0098] Specifically, as shown in FIG. 2, the water supply passages 42 are formed so that the lengths F1 from a connection position 43y with the branch portion 43 to a connection position 44x with the junction portion 44 are the same.

[0099] As a result, for example, the pressure loss experienced by the water flowing through the multiple water supply passages 42 becomes the same among the multiple water supply passages 42, and the water flows evenly in each water supply passage 42, making it easier for the water velocity and the like to become the same or equivalent. Therefore, the water flow is less likely to be disturbed when the water flowing through each water supply passage 42 joins at the junction 44, and disturbance in the discharge of water can be further suppressed.

[0100] In the above, all of the multiple water supply passages 42 are formed to have the same length, but this is not limited to this, and for example, only some of the multiple water supply passages 42 may be formed to have the same length.

[0101] Next, the holding portion 60 will be described with reference to Figures 2, 3, and 5. As shown in Figures 2, 3, and 5, the holding portion 60 is a member that holds a plurality of water supply passages 42. For example, as shown in Figure 5, the holding portion 60 includes a flat portion 61 and a curved portion 62.

[0102] The flat plate portion 61 is a flat plate-like member, and is formed to extend in the vertical direction along the surface of the rear wall portion 12a of the panel portion 12 on the wall surface W side. The curved portion 62 is formed to be curved so as to protrude from the flat plate portion 61 towards the wall surface W. In the curved portion 62, the water supply channel 42 can be arranged (disposed) in the space formed by the curvature. There are multiple curved portions 62 (three in this case) to accommodate the water supply channel 42.

[0103] In the holding portion 60 configured as described above, the water supply passages 42 are arranged in the curved portion 62, and the flat portion 61 is attached to the rear wall portion 12a of the panel portion 12, thereby allowing multiple water supply passages 42 to be held.

[0104] In this way, the water discharge device 1 according to this embodiment is configured to include the retaining portion 60, and therefore, for example, during construction, it is possible to prevent the multiple water supply channels 42 from coming apart, which would reduce workability. Also, in this embodiment, by including the retaining portion 60, it is possible to prevent the water supply channels 42 from being kinked, for example, due to an unintended force acting on the water supply channels 42 during construction.

[0105] The above-described configuration of the holding portion 60 is merely an example and is not intended to be limiting. In other words, the holding portion 60 may be configured to hold a plurality of water supply channels 42 by using, for example, adhesive tape or a band.

[0106] As described above, the water discharge device 1 according to the first embodiment includes a water discharge section 30, a water supply section 40, and a panel section 12. The water supply section 40 supplies water to the water discharge section 30. The panel section 12 is installed to face a wall surface W (installation surface). A storage space 50 that stores at least a part of the water supply section 40 is formed between the panel section 12 and the wall surface W (installation surface). The water supply section 40 is disposed within the storage space 50, and includes a plurality of water supply passages 42 (second water supply passages) that are connected to the downstream side of a water supply pipe 41 (first water supply passage) that is connected to a water supply source. Each of the plurality of water supply passages 42 is formed so that the outer dimensions are smaller than the outer dimensions of the water supply pipe 41, and is flexible.

[0107] This allows the water discharger 1 to be made compact by reducing the depth in the front-rear direction.

[0108] The water discharge device 1 according to the first embodiment includes a water discharge section 30, a water supply section 40, and a panel section 12. The water supply section 40 supplies water to the water discharge section 30. The panel section 12 is installed so as to face a wall surface W (installation surface). A storage space 50 that stores at least a part of the water supply section 40 is formed between the panel section 12 and the wall surface W (installation surface). The water supply section 40 is disposed within the storage space 50, and includes a plurality of water supply passages 42 (second water supply passages) connected to the downstream side of a water supply pipe 41 (first water supply passage) connected to a water supply source, a branching section 43 connected between the water supply pipe 41 and the plurality of water supply passages 42, which branches the water from the water supply pipe 41 to the plurality of water supply passages 42, and a merging section 44 connected downstream of the plurality of water supply passages 42, which merges the water from the plurality of water supply passages 42. Each of the plurality of water supply passages 42 is formed so that its outer dimension is smaller than that of the water supply pipe 41, and has flexibility. At least one of the branch section 43 and the junction section 44 includes a rectification section 43c, 44c that rectifies the water flowing through the water supply section 40.

[0109] This makes it possible to reduce the depth of the water discharge device 1 in the front-rear direction to make it more compact, while suppressing turbulence in the discharged water.

[0110] Second embodiment Next, a second embodiment will be described. In the following description, the same reference numerals are used for parts that are similar to those already described, and duplicated descriptions will be omitted. In the following description of the second embodiment, the configurations corresponding to those of the first embodiment may be described with a "1" added to the beginning of the reference numeral.

[0111] Fig. 13 is a front view of the water discharger 1 according to the second embodiment. Also, Fig. 14 is a cross-sectional view taken along line XIV-XIV in Fig. 13. As shown in Fig. 13 and Fig. 14, the water supply section 40 according to the second embodiment includes a diverter section 143 having a different configuration from the diverter section 43 of the first embodiment.

[0112] For example, the diverter 143 is disposed so as to be located below the counter 20, as shown in Fig. 13. Specifically, the diverter 143 is positioned so that a connection position 143y with the multiple water supply passages 42 connected on the downstream side is below the lower end 21a of the insertion hole 21 of the counter 20. In addition, the diverter 143 is positioned so that a connection position 143x with the water supply pipe 41 connected on the upstream side is below the lower end 21a of the insertion hole 21 of the counter 20.

[0113] As a result, multiple water supply passages 42 are accommodated in the accommodation space 50, and multiple water supply passages 42 are inserted into all of the insertion holes 21 of the counter 20. In other words, the accommodation space 50 and the insertion holes 21 of the counter 20 are configured so that no diverter section 143 is disposed therein.

[0114] This allows the depth D of the storage space 50 to be made smaller and thinner than when it is configured to accommodate, for example, a water supply pipe 41 or a diversion section 143, and therefore the depth of the water discharge device 1 can be made thinner and more compact.

[0115] Furthermore, as described above, since a plurality of water supply passages 42 are inserted into the insertion holes 21 of the counter 20, the ease of installation of the water discharger 1 can be further improved.

[0116] That is, for example, when placing hand-washing basin 10 on counter 20, an operator inserts flexible water supply passage 42 into insertion hole 21 while tilting panel portion 12 forward, and then raises panel portion 12 to install it on wall surface W, thereby making it possible to place hand-washing basin 10 on counter 20. This makes it less likely that wall surface W will be damaged by panel portion 12, for example, and further improves the ease of installation of water discharge device 1.

[0117] Next, the flow dividing section 143 will be described in more detail with reference to Fig. 15 to Fig. 17. Fig. 15 is a front view of the flow dividing section 143, and Fig. 16 is a plan view (top view) of the flow dividing section 143. Fig. 17 is a cross-sectional view taken along line XVII-XVII in Fig. 15.

[0118] 15 to 17, the flow dividing section 143 includes an inlet section 143a, an outlet section 143b, and a flow straightening section 143c. An inlet 143a1 is formed in the inlet section 143a, and the water from the water supply pipe 41 flows in. Each of the multiple outlet sections 143b is formed with an outlet 143b1, and the water flows out to the water supply channel 42.

[0119] Straightening section 143c straightens the water flowing through water supply section 40, more specifically, straightens the water flowing from water supply pipe 41 to water supply channel 42 via flow dividing section 143. For example, straightening section 143c is a section provided between inflow section 143a and outflow section 143b. Straightening section 143c is hollow and formed in a cylindrical shape.

[0120] For example, as shown in Fig. 17, the flow straightening section 143c includes a flow path 143c1 and a collision wall section 143c2. The flow path 143c1 is formed so that the upstream side communicates with the inflow section 143a and the downstream side communicates with the outflow section 143b. The flow path 143c1 is formed so that the diameter of the flow path 143c1 partially increases as it approaches the outflow section 143b, in other words, as it moves downstream.

[0121] The collision wall portion 143c2 is formed at a position opposite to the inlet 143a1 of the inflow portion 143a, on the upper end side (ceiling side) of the flow path 143c1. Since the water flowing in from the inlet 143a1 of the inflow portion 143a flows from below to above, the water flowing in from the inlet 143a1 (in other words, the water flowing from upstream) collides with the collision wall portion 143c2 (see arrow K1).

[0122] As shown by arrow K2, the water that collides with the collision wall portion 143c2 is diverged (branched) into the multiple outflow portions 143b and flows into the corresponding water supply passages 42. In this manner, in the rectification portion 143c, the water from the water supply pipe 41 collides with the collision wall portion 143c2 and is rectified, and the rectified water is diverted and flows into the multiple water supply passages 42 via the outflow portions 143b.

[0123] As a result, the water speed, etc. of each water supply passage 42 becomes the same or equivalent, so that the water flow is less likely to become disturbed when branching or merging, and disturbance of the water discharge can be suppressed, similar to the first embodiment.

[0124] Here, the positional relationship of the outlet 143b1 to the inlet 143a1 in the diverting section 143 will be described in detail with reference to Fig. 16. The outlet 143b1 of the diverting section 143 is positioned so as to be shifted from the inlet 143a1 in a plan view, in other words, when viewed from above and below parallel to the water flow direction.

[0125] Specifically, the flow dividing section 143 is formed such that a central axis B2 of the flow passage cross section at the plurality of outlets 143b1 is eccentric (displaced) from a central axis A2 of the flow passage cross section at the inlet 143a1.

[0126] More specifically, the flow dividing section 143 is formed such that the distances J1 from the central axis B2 of the flow passage cross section at the plurality of outlets 143b1 to the central axis A2 of the flow passage cross section at the inlet 143a1 are all the same. In addition, in the flow dividing section 143, the outlets 143b1 are formed at predetermined intervals (here, 120 degree intervals) around the central axis A2 of the flow passage cross section at the inlet 143a1 in a plan view.

[0127] This allows water to flow more evenly from the diverter 143 to each water supply passage 42. In other words, if the distance from the central axis B2 of the outlet 143b1 to the central axis A2 of the inlet 143a1 differs between the multiple outlets 143b1, for example, water from the inlet 143a1 will flow more easily to the outlet 143b1 closest to the inlet 143a1. As a result, the flow of water will be biased toward the water supply passage 42 connected to the outlet 143b1 closest to the inlet 143a1, and water will not flow evenly to each water supply passage 42, which may cause the water discharge from the water discharger 30 to be disturbed.

[0128] In the second embodiment of the diversion section 143, the distance J1 from the central axis B2 of the multiple outlets 143b1 to the central axis A2 of the inlet 143a1 is formed to be the same for each of them, so that water can flow more evenly from the diversion section 143 to each water supply passage 42, and as a result, turbulence in the water discharge can be effectively suppressed.

[0129] In the above description, all of the plurality of outlets 143b1 are formed so that the distance J1 is the same, but this is not limited thereto. For example, some of the plurality of outlets 143b1 may be formed so that the distance is the same.

[0130] (Third embodiment) Next, a third embodiment will be described. In the following description of the third embodiment, configurations corresponding to those of the first embodiment may be designated by adding a "2" to the beginning of the reference numeral.

[0131] Fig. 18 is an overall perspective view showing a water discharger 1 according to a third embodiment, and Fig. 19 is a front view of the water discharger 1 according to the third embodiment. As shown in Fig. 18 and Fig. 19, the water discharger 1 according to the second embodiment includes a junction section 244 having a different configuration from the junction section 44 of the first embodiment, and a water discharger 230.

[0132] As shown in FIG. 19, the water supply passages 42 are formed so that the lengths F2 from the connection position 43y with the branch portion 43 to the connection position 244x with the junction portion 244 are the same, as in the previous embodiment.

[0133] The junction 244 and the water discharger 230 will be described below with reference to Figures 20 to 22. Figure 20 is a front view of the junction 244 and the water discharger 230, and Figure 21 is a side view of the junction 244 and the water discharger 230. Also, Figure 22 is a cross-sectional view taken along line XXII-XXII in Figure 20.

[0134] 20 and 21, water that has been joined at joining section 244 is supplied to water discharger 230. Water discharger 230 mixes air into the supplied water, for example, using a filter, and spouts bubbly water from water outlet 231, that is, performs foam water spouting. Note that water discharger 230 is not limited to the above-mentioned type that spouts foam water, and may be of another type of water spouting, such as shower water spouting.

[0135] As shown in Fig. 22, the junction 244 includes an inlet 244a, an outlet 244b, and a flow path 244c. The inlet 244a is a portion into which water flows from the multiple water supply passages 42, and there are multiple inlet sections 244a. Each of the multiple inlet sections 244a is formed with an inlet 244a1, into which the water from the water supply passages 42 flows. The outlet 244b is formed with an outlet 244b1, through which the water flows out to the water discharge port 231 (see Fig. 20).

[0136] The flow path 244c communicates with the inflow section 244a (more specifically, the inlet 244a1) on the upstream side, so that water from the multiple water supply paths 42 flows into the flow path 244c via the inflow section 244a and joins with the flow path 244c.

[0137] The flow path 244c is formed so that the downstream side is in communication with the outflow portion 244b (more specifically, the outlet 244b1). The flow path 244c is also formed so that the width in the left-right direction (X-axis direction) becomes smaller as it approaches the outflow portion 244b, in other words, as it moves downstream. As a result, the water that joins in the flow path 244c flows and is discharged to the water discharger 30 (see FIG. 20) through the outlet 244b1 of the outflow portion 244b, as shown by arrow L1, while increasing in speed as it moves downstream.

[0138] In this way, the junction 244 according to the third embodiment does not include a collision wall portion, and straightening due to collision is not performed. This is because the water discharger 230 that performs the above-mentioned foam water discharge is unlikely to cause disturbance in the discharged water due to water turbulence that occurs at the time of merging, so the configuration is such that straightening due to collision is not performed in the junction 244.

[0139] In this way, in the third embodiment, while straightening due to collision is performed at the diversion section 43 (see Figure 19), straightening due to collision is not performed at the merging section 244, making it possible to configure the water discharge device 1 appropriately according to the water discharge form of the water discharge section 230.

[0140] In the third embodiment, the rectification due to collision is not performed at the junction 244, but the present invention is not limited to this, and the rectification due to collision may be performed.

[0141] Furthermore, the water discharger 1 according to the third embodiment is provided with a diverter section 43 as shown in FIG. 19, but instead of this, it may be provided with, for example, the diverter section 143 according to the second embodiment.

[0142] (Modification) Next, a modified example will be described. Fig. 23 is a diagram for explaining the water supply passages and the like according to the modified example. In the modified example, a water supply unit 300 having the functions of the above-mentioned multiple water supply passages, the branching section, and the merging section is used. In Fig. 23, the water discharge section 30 is shown as a schematic block.

[0143] 23, water supply unit 300 is formed in a pouch shape (bag shape) with a liquid-tight periphery. For example, inside water supply unit 300, a plurality of partition walls 345 are provided along the up-down direction parallel to the water flow direction.

[0144] In water supply unit 300, the internal space is partitioned by such partition walls 345 to form a plurality of water supply passages 342. In water supply unit 300, a branch section 343 is formed upstream of the plurality of water supply passages 342, and a junction section 344 is formed downstream of the plurality of water supply passages 342. In addition, water supply pipe 41 is connected to the upstream side of branch section 343 via inflow section 343a. Water discharge section 30 is connected to the downstream side of junction section 344 via outflow section 344a.

[0145] As a result, in water supply unit 300 according to the modified example, water flowing in from water supply pipe 41 via inflow portion 343a is diverted into multiple water supply channels 342 at diverting portion 343, as shown by arrow M1. The diverted water flows through multiple water supply channels 342, and then merges at merging portion 344, as shown by arrow M2, and flows through outflow portion 344a to be discharged to water discharger 30.

[0146] In the modified example, even when the pouch-shaped water supply unit 300 as described above is used, the same effects as those of the previous embodiment can be obtained.

[0147] In the above-described embodiments and modifications, the storage space 50 is configured to store a portion of the water supply unit 40, but is not limited thereto, and may store the entire water supply unit 40.
