Description

[Technical Field]

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

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

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-029124 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-345662 Summary of the Invention [Problem to be solved by the invention]

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

[0005] However, there is a limit to how narrow the depth can be, making it difficult to make it thinner than the water supply pipe it is housed in. While one possible way to make it thinner is to thin the back of the hand basin (back guard), this could result in a decrease in the strength of the back. Thus, the prior art left 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 aspect of the embodiment comprises a water discharge section, a water supply section that supplies water to the water discharge section, and a panel section that is installed opposite an installation surface, wherein a storage space that accommodates at least a portion of the water supply section is formed between the panel section and the installation surface, and the water supply section is arranged within the storage space and includes a plurality of second water supply passages that are connected to the downstream side of a first water supply passage that is connected to a water supply source, and a confluence section that is connected to the downstream side of the plurality of second water supply passages and that merges 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 the confluence 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 it is configured to accommodate, for example, a water supply pipe, thereby making the water discharge device thinner and more compact. Furthermore, by providing multiple water supply channels in the water supply unit with outer dimensions narrower than the water supply pipe, it is possible to discharge water from the water discharge unit while maintaining the amount of water supplied from the water supply pipe. Furthermore, the flexibility of the multiple water supply channels makes it easier to handle the water supply channels during construction and maintenance, preventing a decrease in construction and maintenance efficiency, thereby further improving construction efficiency, etc.

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

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

[0011] The water supply section is further characterized in that it includes a confluence section connected to the downstream side of the plurality of second water supply passages and confluences the water from the plurality of second water supply passages, and the confluence section is accommodated in the accommodation space.

[0012] This prevents kinking from occurring in the water supply line. That is, because the water supply line is flexible, it is more likely to kink, such as break or twist, than if the water supply line were made of a highly rigid material. Therefore, by accommodating the confluence section in the accommodation space as described above, it is possible to prevent, for example, the water supply line from being bent midway and connected to the confluence section, thereby preventing kinking from occurring in the water supply line.

[0013] The second water supply passages are arranged so as to extend vertically within the accommodation space up to a position where they connect with the junction.

[0014] This reduces the amount of unnecessary load 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 when the confluence section and the water discharge section are separate, for example, and allows the water discharge device to be made more compact.

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

[0018] This further improves the ease of installation of the water discharge device. 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 portion forward, and then raises the panel portion 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 panel portion will damage the wall surface, for example, and further improves 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 plurality of second water supply passages, which diverts water from the first water supply passage to the plurality of second water supply passages, and the diversion section is positioned so that the connection position with the plurality of second water supply passages is lower than the lower end of the insertion hole.

[0020] This allows multiple water supply lines to be accommodated in the storage space, and multiple water supply lines to be inserted into all of the counter's insertion holes. In other words, no diverters are placed in the storage space or the counter's insertion holes. Therefore, the depth of the storage space can be made thinner than when, for example, a water supply pipe and diverters are accommodated, making the water discharge device thinner and more compact.

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

[0022] This prevents 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 kinking or the like from occurring in the water supply channels due to unintended forces acting on the channels during construction. [Effects of the Invention]

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the water discharger disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments 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 thereafter are all schematic diagrams.

[0027] For ease of explanation, Fig. 1 illustrates a three-dimensional Cartesian coordinate system that defines mutually orthogonal X-, Y-, and Z-axis directions, with the positive Z-axis direction being the vertically upward direction. This Cartesian coordinate system may also be shown in other drawings used in the following explanation. In the following explanation, for example, based on the state when the water discharger 1 is installed, the positive X-axis direction in the Cartesian coordinate system may be described as "rightward," the negative X-axis direction as "leftward," the positive Y-axis direction as "forward" or "front side," the negative Y-axis direction as "rear" or "back side," the positive Z-axis direction as "upward," and the negative Z-axis direction as "downward."

[0028] As shown in FIG. 1, water discharger 1 is a wall-mounted type and is installed on a wall surface W. 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. In other words, water discharger 1 may also be installed on a wall surface in other locations, such as a washroom or kitchen. 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 comprises a hand wash 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 Figure 2, for ease of understanding, the hand washing basin 10 and counter 20 are shown with imaginary lines so that the water supply unit 40 located on the rear side of the hand washing basin 10, etc. can be seen. In Figure 3, the counter 20 is also shown with imaginary lines.

[0031] Hand washing basin 10 comprises water receiving portion 11 and panel portion 12. Water receiving portion 11 is formed, for example, in a bowl shape, and receives water discharged from water discharge portion 30. Water receiving portion 11 drains the received water through drain hole 13 (see Figure 3 and Figure 4 described below) to drain pipe 14 (see Figure 3) indicated by a two-dot chain line. Note that the term "water" may refer to water at room temperature such as 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 rear side (rear side, negative side of the Y axis) of the water receiving portion 11. That is, the panel portion 12 also serves as a wall portion on the rear side of the water receiving portion 11. Specifically, the panel portion 12 includes a rear wall portion 12a, an upper wall portion 12b, and two side wall portions 12c.

[0033] The rear wall portion 12a is a flat plate-shaped 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 (in the negative Y-axis direction) from the upper end of the rear wall portion 12a. The side wall portions 12c are formed to extend rearward (in the negative Y-axis 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 positioned so as to face the wall surface W. Therefore, 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 part of the water supply unit 40, which will be described later.

[0035] Counter 20 is, for example, a plate-shaped member, and is provided below water receiving portion 11. Counter 20 is installed by being fixed to, for example, a wall surface W or a floor surface (not shown). Water receiving portion 11 is then placed on counter 20.

[0036] Counter 20 is an example of a mounting portion. While counter 20 has been used above as an example of a mounting portion, the present invention is not limited to this, and the mounting portion may be anything, such as a cabinet top (counter), as long as it is capable of mounting water receiving portion 11. Counter 20 is also formed with insertion hole 21 (see FIG. 6) through which a portion of water supply portion 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. 10 and other figures.

[0038] Water supply section 40 is connected to water discharge section 30 and supplies water to water discharge section 30. Water supply section 40, housing space 50, etc. will now be described with reference to Figs.

[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 dotted 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 portion of the water supply unit 40 is provided and housed in such housing 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 work 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 installation of the water discharger 1.

[0042] In addition, 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, water supply section 40 includes water supply pipe 41, water supply channel 42, branch section 43, and junction section 44. Water supply pipe 41 is an example of a first water supply channel, and water supply channel 42 is an example of a second water supply channel.

[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 W. A solenoid valve 101 for an automatic 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, for example, that a user's hand is placed near the water discharger 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. In other words, the water discharger 1 is equipped with an automatic faucet that automatically discharges water when, for example, a user places their hand in the water. The water supply pipe 41 is made of a flexible material (for example, a resin such as silicone), but the material is not limited to this.

[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 splitting 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. 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. Although all of the plurality of water supply paths 42 are set to the same outer dimension E2, 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. As a result, 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 Figure 5 etc. This allows the depth D (see Figure 6) of the accommodation space 50 to be made smaller and thinner, making the water discharger 1 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 be 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 ease of construction and maintenance.

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

[0053] In this way, by making the multiple water supply passages 42 flexible, the water supply passages 42 can be easily handled during construction and maintenance, which prevents a decrease in construction and maintenance efficiency, thereby further improving construction efficiency, etc.

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

[0055] Here, if the water is divided into multiple water supply channels 42 at the dividing section 43 as described above, and then the divided multiple water supply channels 42 are joined at the joining section 44 as described below, there is a risk that the water discharged from the water discharger 30 will be turbulent. In other words, if the water is configured as described above, for example, water will not flow evenly through each water supply channel 42, and the speed of the water flowing through each water supply channel 42 will likely differ from one another. This will cause the flow of water to be turbulent within the water supply section 40, including the water supply channels 42, when the water is divided or joined, and therefore the water discharged from the water discharger 30 will be turbulent.

[0056] Therefore, in the branching section 43, the merging section 44, and the like according to this embodiment, a configuration is provided that can 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 Figures 7 to 9. Figure 7 is a front view of the flow dividing section 43, and Figure 8 is a plan view (top view) of the flow dividing section 43. Figure 9 is a cross-sectional view taken along line IX-IX in Figure 7. For ease of understanding, in Figures 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, flow dividing section 43 includes inflow section 43a, outflow section 43b, and flow rectifying section 43c. Inflow section 43a is a section into which water flows from water supply pipe 41. For example, inflow section 43a is formed with inlet 43a1. Water supply pipe 41 is connected to inlet 43a1, and water from water supply pipe 41 flows in.

[0059] Outlet portions 43b are portions through which water flows out into water supply channels 42, and there are a plurality of them. Since there are a plurality of outlet portions 43b corresponding to water supply channels 42, there are the same number of outlet portions 43b as there are water supply channels 42 (here, three). For example, each of the plurality of outlet portions 43b is formed with an outlet 43b1. The water supply channels 42 are connected to the plurality of outlets 43b1, and water flows out into the water supply channels 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 channel 42 via flow dividing section 43. Straightening by such flow dividing section 43c causes water to flow evenly through each water supply channel 42, and the speed of the water flowing through each water supply channel 42 tends to be the same or equivalent. This makes it difficult for the water flow to be disturbed 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 rectifying portion 43c will be described in detail below. For example, the flow rectifying portion 43c is a portion provided between the inflow portion 43a and the outflow portion 43b. The flow rectifying portion 43c is formed hollow, and as shown in Fig. 9, is formed in an L-shape in side view.

[0062] For example, the flow rectifying 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 its upstream side communicates with the inflow section 43a and its downstream side communicates with the second flow path 43c2. Furthermore, as shown in Fig. 8, the first flow path 43c1 is formed so that its width increases 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 path 43c2 is formed so that its upstream side communicates with the first flow path 43c1 and its downstream side communicates with the plurality of (here, three) outlet portions 43b. The second flow path 43c2 is also formed so as to extend in the up-down direction.

[0064] 9, the collision wall portion 43c3 is formed at a position opposite to the inlet 43a1 of the inflow portion 43a and 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] The water that collides with the collision wall portion 43c3 flows into the second flow path 43c2 as shown by arrow G2, and then branches off (diverges) into the multiple outlet portions 43b and flows into the corresponding water supply paths 42. In this way, 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 portions 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 rectifying section 43c is provided with a collision wall section 43c3 against which water from the water supply pipe 41 collides, so that the water flowing from the water supply pipe 41 to the water supply channel 42 via the diversion section 43 can be rectified with a simple configuration.

[0068] Here, the positional relationship of outlet 43b1 with respect to inlet 43a1 in diverter 43 will be described in detail with reference to Fig. 8. Outlet 43b1 of diverter 43 is positioned so as to be offset from inlet 43a1 in a plan view, in other words, when viewed from above or below parallel to the water flow direction.

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

[0070] To put the above in other words, using the water supply passage 42 connected to the outlet 43b1 and the water supply pipe 41 connected to the inlet 43a1, the central axes (same position as the above-mentioned central axis B1) of the flow path cross sections at the upstream ends of all water supply passages 42 provided downstream of the diversion section 43 are positioned so as to be eccentric (shifted) relative to 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 channel 42. In other words, if the central axis B1 of some of the multiple outlets 43b1 were coaxial with the central axis A1 of the inlet 43a1, water from the inlet 43a1 would flow more easily to those outlets 43b1. As a result, the water flow would be biased toward the water supply channels 42 connected to some of the outlets 43b1, preventing water from flowing evenly to each water supply channel 42, which could result in turbulent water discharge from the water discharger 30 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 to flow water more evenly from the diversion section 43 to each water supply channel 42, and as a result, turbulence in the water discharge can be effectively suppressed.

[0073] Furthermore, 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 of the flow path cross section at the outlet 43b1. 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 direction of the central axis B1 (in other words, in 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 channel 42. In other words, if some of the multiple outlets 43b1 are located at positions that overlap with the inlets 43a1 when viewed from the direction of the central axis B1, water from the inlets 43a1 may more easily flow to those outlets 43b1, which may prevent water from flowing evenly to each water supply channel 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 to flow water 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, we will explain the confluence 44. As shown in Figures 2 and 6, the confluence 44 is connected to the downstream sides of the multiple water supply channels 42. The confluence 44 merges the water from the multiple water supply channels 42.

[0077] 6, the confluence 44 is accommodated in a storage space 50. More specifically, the confluence 44 is accommodated in the storage space 50 together with the water supply passage 42. In other words, the confluence 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, because the water supply passage 42 is flexible, kinking such as bending or twisting is more likely to occur compared to when the water supply passage 42 is made of a highly rigid material. Therefore, in this embodiment, the junction 44 is accommodated in the accommodation space 50, which makes it possible to prevent, for example, the water supply passage 42 from being bent midway and connected to the junction 44, thereby preventing kinking from occurring in the water supply passage 42.

[0079] The multiple water supply passages 42 are arranged in the accommodation space 50 so as to extend vertically to a connection position 44x with the confluence 44. Specifically, the multiple water supply passages 42 are arranged in the accommodation space 50 so as to extend linearly vertically from a connection position 43y with the upstream branch section 43 to a connection position 44x with the downstream confluence 44.

[0080] This makes it difficult for unnecessary loads to be applied to 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 Figures 10 to 12. Figure 10 is a front view of the junction 44, and Figure 11 is a side view of the junction 44. Figure 12 is a cross-sectional view taken along line XII-XII in Figure 10. For ease of understanding, in Figures 10 to 12, the water supply channel 42 connected to the junction 44 is shown by imaginary lines.

[0082] As shown in Figures 10 to 12, the confluence section 44 includes an inlet section 44a, an outlet section 44b (shown only in Figure 12), and a flow rectification section 44c. The inlet sections 44a are sections 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 Figure 12, outflow section 44b is a section that discharges water to water discharger 30. For example, outflow section 44b is formed with outlet 44b1. Outflow outlet 44b1 is connected to water discharge port 31 (see Figure 10) of water discharger 30, and discharges water to water discharge port 31.

[0084] Before describing the flow rectifying section 44c, we will now describe the water discharger 30. As shown in FIG. 10, water discharger 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, just like the water discharge port 31 (see FIG. 12).

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

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

[0087] Returning to the explanation of rectifier 44c, rectifier 44c rectifies the water flowing in water supply section 40, more specifically, rectifies the water flowing from water supply passage 42 to water discharge section 30 via junction 44. Due to the rectification by rectifier 44c, water flows 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 suppressing turbulence in the water discharged from water discharge section 30.

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

[0089] 12, the flow rectifying 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 join together.

[0090] The flow path 44c1 is formed so that its downstream side communicates with the outflow portion 44b (more specifically, the outlet 44b1). The flow path 44c1 is formed so that its width 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 multiple 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 downstream 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 so as 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 inlet section 44a into the flow path 44c1 of the straightening section 44c flows from the bottom to the top, so 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 arrow H2, and flows through the outlet 44b1 of the outlet portion 44b to be discharged to the water discharge portion 30. In this way, in the rectifying 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 outlet 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 the water flow is less likely to be disturbed when the water branches or merges, and disturbances 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 channel 42 collides, so that the water flowing from the water supply channel 42 through the confluence section 44 to the water discharge section 30 can be straightened with a simple configuration.

[0097] Here, the plurality of water supply passages 42 connected to the confluence portion 44 configured as described above are formed to have the same length, which makes it possible to further suppress turbulence in the discharged water.

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

[0099] As a result, for example, the pressure loss experienced by water flowing through the multiple water supply channels 42 becomes the same among the multiple water supply channels 42, and water flows evenly through each water supply channel 42, making it easier for the water speed and other factors to become the same or equivalent. Therefore, the flow of water is less likely to become turbulent when the water flowing through each water supply channel 42 joins at the joining section 44, and turbulence in the discharge of water can be further suppressed.

[0100] In the above, all of the multiple water supply channels 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 channels 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 multiple water supply channels 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-shaped 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 correspond to the water supply channel 42.

[0103] In the holding portion 60 configured as described above, the water supply channels 42 are arranged in the curved portion 62, and the flat plate portion 61 is attached to the rear wall portion 12a of the panel portion 12, thereby allowing multiple water supply channels 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, which can prevent the multiple water supply channels 42 from coming apart during construction, which would reduce workability. Furthermore, in this embodiment, the presence of the retaining portion 60 can prevent unintended forces from acting on the water supply channels 42 during construction, which could cause kinks in the water supply channels 42.

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

[0106] As described above, the water discharger 1 according to the first embodiment comprises a water discharger 30, a water supply unit 40, and a panel unit 12. The water supply unit 40 supplies water to the water discharger 30. The panel unit 12 is installed facing a wall surface W (installation surface). A storage space 50 is formed between the panel unit 12 and the wall surface W (installation surface) to store at least a portion of the water supply unit 40. The water supply unit 40 is disposed within the storage space 50 and includes a plurality of water supply passages 42 (second water supply passages) connected downstream of a water supply pipe 41 (first water supply passage) connected to a water supply source. Each of the plurality of water supply passages 42 is formed so that its outer dimensions are smaller than those 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] Moreover, the water discharger 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 portion 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 diverting section 43 connected between the water supply pipe 41 and the plurality of water supply passages 42 and diverting 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 and merging the water from the plurality of water supply passages 42. Each of the plurality of water supply channels 42 is formed so that its outer dimensions are smaller than those of the water supply pipe 41, and is flexible. At least one of the branch section 43 and the confluence 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 discharger 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, parts that are similar to parts that have already been described will be given the same reference numerals as those already described, and duplicated descriptions will be omitted. In the following description of the second embodiment, parts that correspond to parts in the first embodiment will be given with a "1" prefixed to the reference numeral.

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

[0112] 13, the diverter 143 is disposed so as to be located below the counter 20. Specifically, the diverter 143 is positioned so that a connection position 143y with the plurality of water supply passages 42 connected downstream is below the lower end 21a of the insertion hole 21 of the counter 20. The diverter 143 is also positioned so that a connection position 143x with the water supply pipe 41 connected upstream is below the lower end 21a of the insertion hole 21 of the counter 20.

[0113] As a result, multiple water supply channels 42 are accommodated in the accommodation space 50, and multiple water supply channels 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 arranged therein.

[0114] This allows the depth D of the storage space 50 to be made smaller and thinner than when it is configured to store, for example, a water supply pipe 41 or a diverter 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 and installs it on wall surface W, thereby making it possible to place hand washing basin 10 on counter 20. This makes it less likely that panel portion 12 or the like will damage wall surface W, further improving 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 143a, an outlet 143b, and a flow straightening section 143c. An inlet 143a1 is formed in the inlet 143a, through which water from the water supply pipe 41 flows in. An outlet 143b1 is formed in each of the multiple outlets 143b, through which 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 diverter section 143. For example, straightening section 143c is a section provided between inlet section 143a and outlet section 143b. Straightening section 143c is hollow and formed in a cylindrical shape.

[0120] 17, the flow rectifying portion 143c includes a flow path 143c1 and a collision wall portion 143c2. The flow path 143c1 is formed so that its upstream side communicates with the inflow portion 143a and its downstream side communicates with the outflow portion 143b. The flow path 143c1 is also formed so that its diameter partially increases as it approaches the outflow portion 143b, in other words, as it moves downstream.

[0121] The collision wall portion 143c2 is located opposite the inlet 143a1 of the inflow portion 143a and is formed 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 plurality of outflow portions 143b and flows into the corresponding water supply channels 42. In this way, 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 plurality of water supply channels 42 via the outflow portions 143b.

[0123] This makes the water speed, etc. of each water supply passage 42 the same or equivalent, so the water flow is less likely to be disturbed when the water branches or merges, and disturbances in the water discharge can be suppressed, just like in the first embodiment.

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

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

[0126] More specifically, the flow dividing section 143 is formed so that the distances J1 from the central axis B2 of the flow path cross section at the plurality of outlets 143b1 to the central axis A2 of the flow path 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 path 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 channel 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 among multiple outlets 143b1, water from the inlet 143a1 will more easily flow to the outlet 143b1 that is closest to the inlet 143a1. As a result, the flow of water will be biased toward the water supply channel 42 that is connected to the outlet 143b1 that is closest to the inlet 143a1, preventing water from flowing evenly to each water supply channel 42 and causing disturbances in the discharge of water from the water discharger 30.

[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, making it possible to flow water more evenly from the diversion section 143 to each water supply channel 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, and 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 "2" to the beginning of the reference numeral.

[0131] Fig. 18 is an overall perspective view showing a water discharger 1 according to the 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 multiple water supply channels 42 are formed so that the lengths F2 from the connection position 43y with the branch section 43 to the connection position 244x with the junction section 244 are the same, as in the previous embodiment.

[0133] The junction section 244 and water discharge section 230 will be described below with reference to Figures 20 to 22. Figure 20 is a front view of the junction section 244 and water discharge section 230, and Figure 21 is a side view of the junction section 244 and water discharge section 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 using, for example, a filter, and discharges bubbly water from water discharge port 231, i.e., performs foam water discharge. Note that water discharger 230 is not limited to the type that discharges foam water described above, and may also discharge water in other forms, such as shower water.

[0135] As shown in Figure 22, the confluence section 244 includes an inlet section 244a, an outlet section 244b, and a flow path 244c. There are multiple inlet sections 244a, and these are sections into which water flows in from multiple water supply channels 42. Each of the multiple inlet sections 244a is formed with an inlet 244a1, through which water from the water supply channels 42 flows in. The outlet section 244b is formed with an outlet 244b1, through which water flows out to the water discharge port 231 (see Figure 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 passages 42 flows into the flow path 244c via the inflow section 244a and joins together.

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

[0138] In this way, the confluence section 244 according to the third embodiment does not have a collision wall section, and is designed to prevent rectification due to collisions. This is because the water discharge section 230, which performs the foam water discharge described above, is less likely to experience turbulence in the discharged water due to water turbulence that occurs when the flows join, so the confluence section 244 is designed to prevent rectification due to collisions.

[0139] In this way, in the third embodiment, by configuring the water discharging device 1 so that collision-induced straightening is performed at the diversion section 43 (see Figure 19), while collision-induced straightening is not performed at the confluence section 244, it is possible to configure the water discharging device 1 appropriately according to the water discharging form of the water discharging section 230.

[0140] In the third embodiment, the rectification due to collisions is not performed at the junction 244, but the present invention is not limited to this, and the rectification due to collisions 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] (Variation) 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, branching section, and 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 vertical direction parallel to the direction of water flow.

[0144] In water supply unit 300, the internal space is partitioned by such partition walls 345, thereby forming 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 downstream 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 inlet 343a is diverted into multiple water supply channels 342 at diverting section 343, as shown by arrow M1. The diverted water flows through multiple water supply channels 342, then merges at junction 344, as shown by arrow M2, and flows and is discharged to water discharger 30 via outlet 344a.

[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, storage space 50 is configured to accommodate a portion of water supply unit 40, but this is not limited to this and storage space 50 may accommodate the entire water supply unit 40. In other words, storage space 50 only needs to accommodate at least a portion of water supply unit 40.

[0148] In the first and second embodiments described above, both the branching section 43, 143 and the merging section 44 are provided with a rectifying section, but it is also possible to provide a rectifying section in either one of the branching section 43, 143 and the merging section 44. In other words, it is sufficient that at least one of the branching section 43, 143 and the merging section 44 is provided with a rectifying section.

[0149] Furthermore, in the above description, the water discharger 1 is provided with an automatic faucet, but the invention is not limited to this and may be provided with a manual faucet.
