Description

[Technical Field]

[0001] The present invention relates to a water discharge device. [Background technology]

[0002] BACKGROUND ART Water discharge devices that discharge water (including hot water) toward a bather have been known.

[0003] For example, Patent Document 1 proposes a water discharge device provided with a lid for maintenance of one of the water discharge flow paths. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-134056 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the technology described in Patent Document 1, when a water discharge flow path is provided in addition to the one water discharge flow path, it is not easy to perform maintenance on the other water discharge flow path that is not provided with a lid portion.

[0006] In view of the above problems, the present invention aims to provide a water discharge device that facilitates maintenance of not only one water discharge flow path but also other water discharge flow paths. [Means for solving the problem]

[0007] To solve the above problem, according to a first aspect of the present invention, the following water discharge device is provided: This water discharge device comprises a first wall portion forming the upper surface of a first water discharge flow path having a first water discharge outlet that discharges water toward the bathtub, a second wall portion forming the lower surface of the first water discharge flow path and forming the upper surface of a second water discharge flow path having a second water discharge outlet that discharges water toward the bathtub, a first lid portion that penetrates the first wall portion and is configured to be detachable from the first wall portion, and a second lid portion that penetrates the second wall portion and is configured to be detachable from the second wall portion.

[0008] According to this configuration, maintenance of not only the first water discharge flow path but also the second water discharge flow path is made easier compared to when the second lid portion is not provided.

[0009] Moreover, in the water discharge device according to the second aspect of the present invention, the second lid portion forms part of the lower surface of the first water discharge flow path and part of the upper surface of the second water discharge flow path.

[0010] With this configuration, compared to when the second lid portion does not form part of each water discharge flow path, it is possible to prevent the second lid portion from forming recesses or protrusions that disrupt the water flow within each water discharge flow path.

[0011] Moreover, in the water discharge device according to the third aspect of the present invention, at least a part of the first lid portion is provided in a position that overlaps with the second lid portion in a plan view.

[0012] With this configuration, the second lid portion is easier to attach and detach compared to when the first lid portion and the second lid portion are positioned so that they do not overlap, making maintenance of the second water discharge flow path even easier.

[0013] Moreover, in the water discharge device according to the fourth aspect of the present invention, at least a part of the second lid portion is provided closer to the second water discharge port than the first lid portion.

[0014] This configuration makes it easier to maintain the second water discharge port side of the second water discharge flow path compared to when the second lid portion is provided on the opposite side of the first lid portion from the second water discharge port.

[0015] Moreover, in the water discharger according to the fifth aspect of the present invention, the area of ​​the first lid portion is larger than the area of ​​the second lid portion or is the same as the area of ​​the second lid portion in a plan view.

[0016] With this configuration, the second lid portion can be more easily attached and detached through the opening in the first wall portion formed by removing the first lid portion, compared to when the second lid portion has a larger area than the first lid portion.

[0017] Moreover, in the water discharge device according to a sixth aspect of the present invention, the first lid portion or the second lid portion has a position holding portion that is provided in contact with the first lid portion and the second lid portion.

[0018] According to this configuration, it is possible to prevent the second lid portion from shifting in position compared to when no position maintaining portion is provided.

[0019] Moreover, in the water discharge device according to the seventh aspect of the present invention, the position maintaining portion has a streamlined shape.

[0020] With this configuration, it is possible to prevent the position maintaining portion from disturbing the water flow in the first water discharge channel, compared to when the position maintaining portion is not streamlined.

[0021] Moreover, in the water discharge device according to the eighth aspect of the present invention, the second lid portion is connected to the first lid portion via the position holder.

[0022] With this configuration, the second lid part can be attached and detached at the same time as the first lid part is attached and detached.

[0023] Moreover, in the water discharge device according to a ninth aspect of the present invention, the first lid portion, the second lid portion, and the position holding portion are integrally formed.

[0024] According to this configuration, it is possible to prevent the second lid portion from shifting in position compared to when the first lid portion and the second lid portion are provided as separate bodies. [Effects of the Invention]

[0025] According to the water discharge device of the present invention, maintenance of not only one water discharge flow path but also other water discharge flow paths can be facilitated. [Brief explanation of the drawings]

[0027] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. To facilitate understanding of the description, the same components in the drawings will be denoted by the same reference numerals as much as possible, and duplicated descriptions will be omitted.

[0028] ---First embodiment--- First, a bathtub apparatus 3 to which a water discharger 1A according to a first embodiment of the present invention is applied will be described.

[0029] <Overall structure> FIG. 1 is a schematic perspective view showing a bathtub apparatus 3 to which a water discharger 1A according to a first embodiment of the present invention is applied, and FIG. 2 is a top view of the bathtub apparatus 3 shown in FIG.

[0030] As shown in Figures 1 and 2, a bathtub apparatus 3 to which a water discharger 1A according to one embodiment of the present invention is applied comprises a bathtub 2 and a water supply unit 10 that supplies hot and cold water into the bathtub 2. The water discharger 1A is installed in the bathtub 2. The bathtub 2 stores water (including hot water) supplied from the water supply unit 10. The water discharger 1A is formed with a water outlet 4 that discharges water into the bathtub 2.

[0031] The bathtub 2 has a bottom 2a, a vertical wall 2b on the short side that comes into contact with the back of the bather H, a side wall 2d on the long side of the bathtub 2, and an upper end (rim) 2c that is connected to the upper part of the vertical wall 2b and forms the upper surface of the bathtub 2. The water discharge device 1A is installed on the inner edge of the upper end 2c of the bathtub 2.

[0032] For ease of explanation, as shown in the figure, the direction parallel to the water spouting direction of water discharger 1A in a plan view is referred to as the front-to-rear direction, the direction in which water discharger 1A is installed in bathtub 2 is referred to as the rear, and the direction in which water discharger 1A is not installed is referred to as the front. Furthermore, the direction perpendicular to the front-to-rear direction in a plan view is referred to as the left-to-right direction, and when viewing water outlet 4 from the front, the right side is referred to as the right direction, and the left side is referred to as the left direction. The vertical up-down direction is referred to as the height direction, with the vertically upward direction referred to as the upward direction and the vertically downward direction referred to as the downward direction. The front-to-rear direction, the left-to-right direction, and the height direction are perpendicular to each other. These directions are not limited to being strictly perpendicular, but also include cases in which they are nearly perpendicular. These directional notations do not limit the usage orientation of water discharger 1A, and water discharger 1A can be used in any orientation depending on the application.

[0033] The rear side of the vertical wall 2b of the bathtub 2 is a backrest section 7 against which the bather H in a bathing position can rest his or her back. A high-pressure water outlet section 18 is formed on the vertical wall 2b. The upper end section 2c is set at a height relatively close to the upper body of the bather H sitting in the bathtub, such as the head, neck, or shoulders. A first water intake 6, a second water intake 22, and a water temperature sensor (detection section) 9 are formed on the side wall 2d. A pillow section 8 is located above the backrest section 7, against which the bather H in a bathing position can rest his or her head. The water outlet 4 is located between the backrest section 7 and the pillow section 8.

[0034] Bathtub 2 is a type of bathtub in which the upper part of the wall of bathtub 2 is formed in a horizontal arc shape. Bathtub 2 may also be a type of bathtub in which the upper part of the wall of bathtub 2 is formed in a horizontal arc shape, a circular bathtub, or a type of bathtub in which vertical wall 2b forms the long side.

[0035] FIG. 3 is a schematic cross-sectional view of the bathtub apparatus 3 taken along line III-III in FIG. 2, and FIG. 4 is a side view of the bathtub apparatus 3 shown in FIG. 1. As shown in FIGS. 3 and 4, the bathtub apparatus 3 further includes a first flow path 13, a pump 11, a three-way valve 12, a second flow path 14, a third flow path 16, a high-pressure water discharge unit 18, a jet pump unit 20, a fourth flow path 24, an uprising pipe 26, a control unit 28, a water temperature sensor (detection unit) 9, and an operation unit 30. The first flow path 13 extends from the first water intake 6. The second flow path 14 extends from the three-way valve 12 toward the water discharge port 4. The third flow path 16 extends from the three-way valve 12 separately from the second flow path 14. The high-pressure water discharge unit 18 discharges water supplied from the third flow path 16 into the bathtub 2 at high pressure. The fourth flow path 24 extends from the second water intake 22 to the jet pump unit 20. The detection unit 9 detects the temperature of the water in the bathtub 2. The detection unit 9 is controlled by the control unit 28. It is more preferable that the detection unit 9 is formed on the inner wall of the bathtub 2 on the wall side where the first water intake 6 or the second water intake 22 is formed, rather than on the wall side where the water discharge device 1A is installed.

[0036] Pump 11 is provided on first flow path 13 and sucks water from bathtub 2 and pumps it downstream. Pump 11 is electrically connected to control unit 28 and is controlled by control unit 28.

[0037] The three-way valve 12 controls the flow of water at the downstream end of the first flow path 13. The three-way valve 12 can selectively supply water supplied from the first flow path 13 to both or either the second flow path 14 and the third flow path 16. The three-way valve 12 can freely change the flow rate distribution ratio. The three-way valve 12 is electrically connected to a control unit 28 and is electrically controlled to open and close by the control unit 28. The second flow path 14 forms a flow path extending from the three-way valve 12 to the jet pump unit 20.

[0038] The control unit 28 controls the pump 11 and the three-way valve 12. The control unit 28 is attached to the back side of the bathroom wall (not shown). The control unit 28 is electrically connected to the pump 11, the three-way valve 12, the operation unit 30, etc., and is capable of operating each of the above-mentioned parts. The control unit 28 controls each device in response to an operation signal from the operation unit 30 or in accordance with a stored program, etc. The control unit 28 is equipped with a storage device such as a memory and a calculation unit that enable it to appropriately control the water discharge device 1A.

[0039] The operating unit 30 is operated by the bather H. The operating unit 30 is provided so that the bather H can turn the water discharge device 1A on and off, and is attached to a wall in the bathroom. Information on the bather H's operation of the operating unit 30 is sent from the operating unit 30 to the control unit 28 via an electrical signal. Specifically, for example, when the bather H operates the operating unit 30, the water supply unit 10 supplies hot water into the bathtub 2. Furthermore, when the bather H operates the operating unit 30, the temperature of the water that the water supply unit 10 supplies into the bathtub 2 is set.

[0040] The jet pump unit 20 is provided in the downstream portion of the second flow path 14. The jet pump unit 20 includes a chamber portion 32 in which water drawn in by the jet pump action is stored, and a jet nozzle 34 arranged at the downstream end of the second flow path 14. By employing the jet pump unit 20, the water discharge device 1A can discharge a large amount of shoulder-water water from the water discharge port 4 using a relatively small pump 11.

[0041] Chamber 32 forms a box-shaped water storage chamber, and the downstream end of fourth flow path 24 is connected to chamber 32. Chamber 32 is connected to bathtub 2. A jet nozzle 34 is attached to the bottom of chamber 32, facing vertically upward. An opening is formed in the upper surface of chamber 32 at a position opposite jet nozzle 34, and riser pipe 26 extends upward from this opening.

[0042] The jet nozzle 34 injects water supplied from the pump 11 into the riser pipe 26 through the chamber 32. Because the jet nozzle 34 injects water so that it passes through the chamber 32, it induces a jet pump action that draws water from within the chamber 32. The jet nozzle 34 is formed so that the diameter of its internal flow path is narrower than the diameter of the second flow path 14 upstream of the jet nozzle 34. Therefore, the water pumped by the pump 11 is further accelerated within the jet nozzle 34 and is ejected from the jet nozzle 34 as a high-speed water stream. The high-speed jet ejected from the jet nozzle 34 draws in water from the chamber 32, increasing its flow rate and decreasing its flow velocity.

[0043] The rising pipe 26 extends vertically upward from the jet pump unit 20. Specifically, the rising pipe 26 forms a circular tubular flow path that extends vertically upward from the chamber portion 32. The water discharger 1A discharges the water supplied from the rising pipe 26 into the bathtub 2. The tip of the rising pipe 26 on the water discharger 1A side branches into multiple parts.

[0044] <Detailed configuration of water discharge device 1A> FIG. 5 is a side cross-sectional view of the water discharger 1A shown in FIG. 1 with the pillow part 8 removed.

[0045] 5, the water discharger 1A includes a wall portion 51 and a lid portion 40. The wall portion 51 and the lid portion 40 form a first water discharge flow path 80, an introduction pipe 81, a second water discharge flow path 90, and a water intake port 91. As the water discharge port 4 described above, the first water discharge flow path 80 includes a first water discharge port 805, and the second water discharge flow path 90 includes a second water discharge port 905.

[0046] Wall 51 comprises first wall 511, second wall 513, and third wall 515. Wall 51 is a molded resin product, and is formed by assembling first wall 511, second wall 513, and third wall 515 with fasteners such as screws. A water conduit 53 protruding downward is formed at the bottom of third wall 515. Water conduit 53 is inserted through bathtub 2, and the aforementioned riser pipe 26 is connected to its tip. A water intake 91 is formed inside water conduit 53, and bathwater is pressure-fed from pump 11 through riser pipe 26. An inlet pipe 81 is provided in second wall 513, penetrating second wall 513. Inlet pipe 81 is a pipe that supplies bathwater from the branched tip of riser pipe 26 to first water discharge flow path 80.

[0047] The first wall portion 511 has a horizontally long, slit-shaped first water outlet 805 formed in the front portion. A first water discharge flow path 80 that connects the inlet pipe 81 and the first water outlet 805 is formed inside the first wall portion 511. The first wall portion 511 forms the upper surface of the first water discharge flow path 80, and the second wall portion 513 forms the lower surface of the first water discharge flow path 80. The first water discharge flow path 80 has a throttle flow path 801, a first storage portion 803, and a first water outlet 805. The first water discharge flow path 80 is formed horizontally long so that its cross section is wider than its height. The first storage portion 803 temporarily stores water flowing in from the inlet pipe 81 as reserved water. The throttle flow path 801 is formed so that the height of the first water discharge flow path 80 is smaller than that of the first storage portion 803. The stored water in the first storage section 803 is sent out to the first water outlet 805 through the throttle flow path 801. Specifically, the stored water is throttled as it passes through the throttle flow path 801, increasing the flow rate, and the water is forcefully discharged from the first water outlet 805 as a water flow W1.

[0048] A second water outlet 905 is formed in the front part of the second wall portion 513. A second water outlet flow path 90 that connects the water conduit 53 and the second water outlet 905 is formed inside the second wall portion 513. The second wall portion 513 forms the upper surface of the second water outlet flow path 90, and the third wall portion 515 forms the lower surface of the second water outlet flow path 90. The second water outlet flow path 90 has a jet flow path 901 and a second water outlet 905. Water is sent from the water intake 91 through the jet flow path 901 to the second water outlet 905 and is sprayed as a jet W2.

[0049] The lid portion 40 includes a first lid portion 401, a second lid portion 403, and a position-maintaining portion 60. The first lid portion 401 and the position-maintaining portion 60 are integrally formed.

[0050] The first lid portion 401 is provided so as to penetrate the first wall portion 511. The first lid portion 401 also forms part of the upper surface of the first water discharge flow path 80. Specifically, the first lid portion 401 forms part of the upper surface (ceiling wall) of the first storage portion 803. The left-right dimension of the first lid portion 401 is preferably at least half the left-right dimension of the first water discharge flow path 80, in order to facilitate maintenance of the first water discharge flow path 80. The first lid portion 401 is also formed of an elastically deformable soft material. The first lid portion 401 is pressed against the first wall portion 511 and elastically deforms, so that the first lid portion 401 is attached in close contact with the first wall portion 511.

[0051] The first lid portion 401 is configured so that it can be attached and detached from the first wall portion 511 while the water discharger 1A remains attached to the bathtub 2. Specifically, the first lid portion 401 has gripping claws or handles (not shown) on the top surface of the first lid portion 401. The first lid portion 401 is gripped by the gripping claws or handles and attached and detached from the first wall portion 511. By removing the first lid portion 401, an opening that communicates with the first water discharge flow path 80 is formed in the first wall portion 511. By providing the first lid portion 401, it becomes easy to perform maintenance such as cleaning of the first water discharge flow path 80 while the water discharger 1A remains attached to the bathtub 2.

[0052] The second lid portion 403 is provided so as to penetrate the second wall portion 513. The second lid portion 403 also forms part of the lower surface of the first water discharge flow path 80 and part of the upper surface (ceiling wall) of the second water discharge flow path 90. The second lid portion 403 is formed from an elastically deformable soft material. The second lid portion 403 is pressed against the second wall portion 513 and elastically deforms, so that the second lid portion 403 is attached in close contact with the second wall portion 513.

[0053] The second lid portion 403 is configured so that it can be attached and detached from the second wall portion 513 while the water discharger 1A remains attached to the bathtub 2. Specifically, the second lid portion 403 has a gripping claw or handle (not shown) on the upper surface of the second lid portion 403. The second lid portion 403 is gripped by the gripping claw or handle and attached and detached from the second wall portion 513. Furthermore, to prevent interference with the water flow in the first water discharge flow path 80, it is preferable that the gripping claw or handle be provided near the left and right ends of the first water discharge flow path 80. By removing the second lid portion 403, an opening communicating with the second water discharge flow path 90 is formed in the second wall portion 513. Therefore, providing the second lid portion 403 makes it easy to perform maintenance, such as cleaning, of the second water discharge flow path 90 while the water discharger 1A remains attached to the bathtub 2.

[0054] The position-retaining unit 60 is provided on the first lid portion 401. The position-retaining unit 60 abuts against the first lid portion 401 and the second lid portion 403, thereby restricting movement of the second lid portion 403 relative to the second wall portion 513. This prevents the second lid portion 403 from shifting position and forming a recess or protrusion that would hinder the water flow in the first water discharge flow path 80 or the second water discharge flow path 90. The position-retaining unit 60 also restricts movement of the first lid portion 401 relative to the first wall portion 511. This prevents the first lid portion 401 from shifting position and forming a recess or protrusion that would hinder the water flow in the first water discharge flow path 80.

[0055] The position-maintaining unit 60 has a streamlined shape. For example, the position-maintaining unit 60 is a circular cylinder or an elliptical cylinder. This makes it possible to prevent the position-maintaining unit 60 from interfering with the water flow in the first water discharge flow path 80, compared to when the position-maintaining unit 60 is a rectangular parallelepiped that is not streamlined.

[0056] At least a portion of the first lid portion 401 is provided in a position overlapping with the second lid portion 403 in a plan view. Here, the second lid portion 403 is removed through an opening in the first wall portion 511 that is created by removing the first lid portion 401. Therefore, by providing the first lid portion 401 in a position overlapping with the second lid portion 403 in a plan view, the second lid portion 403 is easily visible from outside the water discharger 1, and the distance between the second lid portion 403 and the opening in the first wall portion 511 is shortened, making it easier to attach and detach the second lid portion 403. Furthermore, the area of ​​the first lid portion 401 is larger than the area of ​​the second lid portion 403 in a plan view. With this configuration, the opening in the first wall portion 511 is larger than when the area of ​​the second lid portion 403 is larger than the first lid portion 401, making it easier to attach and detach the second lid portion 403. The ease of attachment and detachment of the second lid portion 403 makes it even easier to perform maintenance such as cleaning of the second water discharge flow path 90. Furthermore, at least a portion of the second lid portion 403 is provided closer to the second water discharge port 905 (forward) than the first lid portion 401. In other words, at least a portion of the second lid portion 403 is provided forward of the first lid portion 401. This configuration makes it easier to perform maintenance such as cleaning in front of the second water discharge flow path 90.

[0057] <Action and effect> As described above, the water discharge device 1A of this embodiment comprises a first wall portion 511 that forms the upper surface of the first water discharge flow path 80, which has a first water discharge outlet 805 that discharges water toward the bathtub 2; a second wall portion 513 that forms the lower surface of the first water discharge flow path 80 and forms the upper surface of the second water discharge flow path 90, which has a second water discharge outlet 905 that discharges water toward the bathtub 2; a first lid portion 401 that is provided to penetrate the first wall portion 511 and is configured to be detachable from the first wall portion 511; and a second lid portion 403 that is provided to penetrate the second wall portion 513 and is configured to be detachable from the second wall portion 513.

[0058] According to this configuration, maintenance of not only the first water discharge flow path 80 but also the second water discharge flow path 90 is made easier compared to when the second lid portion 403 is not provided.

[0059] Furthermore, in the water discharge device 1A, the second lid portion 403 forms part of the lower surface of the first water discharge flow path 80 and part of the upper surface of the second water discharge flow path 90.

[0060] With this configuration, compared to when the second lid portion 403 does not form part of each water discharge flow path 80, 90, it is possible to prevent the second lid portion 403 from forming a recess or protrusion that would disrupt the water flow within each water discharge flow path 80, 90.

[0061] In addition, in the water discharger 1A, at least a part of the first lid part 401 is provided at a position where it overlaps with the second lid part 403 in a plan view.

[0062] With this configuration, the second lid portion 403 is easier to attach and remove compared to when the first lid portion 401 and the second lid portion 403 are positioned in a position where they do not overlap, making maintenance of the second water discharge flow path 90 even easier.

[0063] Furthermore, in the water discharger 1A, at least a part of the second lid part 403 is provided closer to the second water discharge port 905 than the first lid part 401.

[0064] This configuration makes maintenance of the second water outlet 905 side of the second water outlet flow path 90 easier than when the second lid portion 403 is located on the opposite side of the second water outlet 905 from the first lid portion 401.

[0065] In addition, in the water discharger 1A, the area of ​​the first lid portion 401 is larger than the area of ​​the second lid portion 403 or is the same as the area of ​​the second lid portion 403 in a plan view.

[0066] With this configuration, it is easier to attach and detach the second lid portion 403 through the opening in the first wall portion 511 formed by removing the first lid portion 401, compared to when the second lid portion 403 has a larger area than the first lid portion 401.

[0067] Moreover, in the water discharger 1A, the first lid part 401 or the second lid part 403 has a position holding part 60 that is provided in contact with the first lid part 401 and the second lid part 403.

[0068] According to this configuration, it is possible to prevent the second lid part 403 from shifting position, compared to when the position holder 60 is not provided.

[0069] Moreover, in the water discharger 1A, the position holding part 60 has a streamlined shape.

[0070] With this configuration, the position-maintaining section 60 can be prevented from disturbing the water flow in the first water discharge flow path 80, compared to when the position-maintaining section 60 is not streamlined.

[0071] ---Second embodiment--- Next, a water discharge device 1B according to a second embodiment will be described.

[0072] The second embodiment differs from the first embodiment in the configuration of the lid portion 40. Note that a description of the same points as in the first embodiment will be omitted.

[0073] FIG. 6 is a side cross-sectional view of a water discharger 1B according to the second embodiment, with the pillow part 8 removed.

[0074] 6, second lid portion 403 is connected to first lid portion 401 via position-maintaining portion 60. Specifically, first lid portion 401, second lid portion 403, and position-maintaining portion 60 are integrally formed. In other words, lid portion 40 is integrally formed.

[0075] Because second lid portion 403 is connected to first lid portion 401 via position holder 60, second lid portion 403 can be attached and detached at the same time as first lid portion 401. Specifically, if lid portion 40 is formed as a separate body, when removing second lid portion 403, first lid portion 401 is removed, and then second lid portion 403 is removed from the opening opened in first wall portion 511. On the other hand, if lid portion 40 is formed as an integral body, second lid portion 403 can be removed at the same time as first lid portion 401 is removed.

[0076] Furthermore, because the lid portion 40 is integrally formed, it is possible to prevent the second lid portion 403 from shifting position, compared to when the lid portion 40 is formed separately. When the lid portion 40 is formed separately, the second lid portion 403 is positioned so as not to form recesses or protrusions that would obstruct the water flow in each of the water discharge channels 80, 90 when attached. On the other hand, when the lid portion 40 is integrally formed, it is possible to position the second lid portion 403 according to the position of the first lid portion 401. This prevents, for example, the second lid portion 403 from being pushed too far toward the second water discharge channel 90 when attached, and prevents the second lid portion from forming recesses or protrusions that would obstruct the water flow in each of the water discharge channels 80, 90. Furthermore, compared to when the second lid portion 403 is connected to the first lid portion 401 via the position-retaining portion 60 with fasteners such as screws, the integral formation of the lid portion 40 prevents the connection portion from obstructing the water flow in the first water discharge channel 80.

[0077] <Action and effect> As described above, in the water discharger 1B according to this embodiment, the second lid part 403 is connected to the first lid part 401 via the position holder 60.

[0078] According to this configuration, the second lid part 403 can be attached and detached at the same time as the first lid part 401 is attached and detached.

[0079] Moreover, in the water discharger 1B, the first lid portion 401, the second lid portion 403, and the position holder 60 are integrally formed.

[0080] According to this configuration, displacement of second lid portion 403 can be prevented more effectively than in the case where first lid portion 401 and second lid portion 403 are provided as separate bodies.

[0081] ---Variations--- The present invention is not limited to the above-described embodiments. In other words, designs that are produced by those skilled in the art with appropriate design modifications to the above-described specific examples are also included within the scope of the present invention as long as they include the features of the present invention. Furthermore, the elements of the above-described embodiments and the following modifications can be combined to the extent technically possible, and such combinations are also included within the scope of the present invention as long as they include the features of the present invention.

[0082] For example, Fig. 7 is a side cross-sectional view of a water discharger 1C according to a modified example with the pillow portion 8 removed. As shown in Fig. 7, the first lid portion 401 of the lid portion 40 and the position-retaining portion 60 are integrally formed. Furthermore, the first lid portion 401 forms most of the first wall portion 511 at the rear of the upper surface of the first storage portion 803, and most of the first wall portion 511 on the rear side surface of the first storage portion 803. Comparing this configuration with the water discharger 1A of the first embodiment, a larger opening is formed in the first wall portion 511 when the first lid portion 401 is removed. This makes maintenance of the first water discharge flow path 80 and the second water discharge flow path 90 even easier.

[0083] In the first embodiment, the components of the lid portion 40 are formed from an elastically deformable soft material. However, the material of the lid portion 40 is not limited to this. For example, the lid portion 40 may be formed from a resin material. For example, the first lid portion 401 may be provided with a locking claw and the first wall portion 511 may be provided with a locking hole, thereby engaging the first lid portion 401 with the first wall portion 511 and attaching the first lid portion 401 to the first wall portion 511. Furthermore, the first lid portion 401, the position retaining portion 60, and the second lid portion 403 may be formed from different materials. For example, the first lid portion 401 may be formed from a resin material, and the position retaining portion 60 and the second lid portion 403 may be formed from a soft material. Furthermore, the portion of the first wall portion 511 that contacts the first lid portion 401 or the portion of the second wall portion 513 that contacts the second lid portion 403 may be formed from a soft material. For example, a hollow cylindrical member made of a soft material may be disposed on the portion of second wall portion 513 that contacts second lid portion 403. With this configuration, for example, the hollow cylindrical member is pressed against second lid portion 403 and elastically deforms, thereby attaching second lid portion 403 to second wall portion 513 in close contact therewith.

[0084] In addition, the water discharge device 1A may have two or more first lid portions 401 or two or more second lid portions 403, for example, one first lid portion 401 and two second lid portions 403.

[0085] In addition, although the above example shows a configuration in which at least a portion of first lid portion 401 is provided in a position that overlaps with second lid portion 403 in a plan view, first lid portion 401 may be provided in a position that does not overlap with second lid portion 403 in a plan view. In addition, the above example shows a configuration in which the area of ​​first lid portion 401 is larger than the area of ​​second lid portion 403 in a plan view, but the area of ​​first lid portion 401 may be smaller than or the same as the area of ​​second lid portion 403. In addition, the above example shows a configuration in which at least a portion of second lid portion 403 is provided closer to second spout 905 (forward) than first lid portion 401, but second lid portion 403 may be provided rearward than first lid portion 401.

[0086] Furthermore, the water discharger 1A may be provided with only one second water discharge flow path 90, or with two or more. For example, the second water discharge flow paths 90 may be provided separately on the left and right sides of the water discharger 1A, or may be provided in the center of the water discharger 1A in the left-right direction. The water discharger 1A may be provided with only one second water discharge outlet 905, or with two or more second water discharge outlets 905. For example, the jet flow W2 may be discharged from two second water discharge outlets 905 branching off from one second water discharge flow path 90, or each of the two second water discharge flow paths 90 may have one second water discharge outlet 905, and the jet flow W2 may be discharged from each second water discharge outlet 905.

[0087] In addition, although one example has been given in which the rising pipe 26 branches and water flows from the water conduit 53 into the second water discharge flow path 90 and from the introduction pipe 81 into the first water discharge flow path 80, for example, water may also flow into the first water discharge flow path 80 via the second water discharge flow path 90. Furthermore, a three-way pipe or the like may be connected to the tip of the rising pipe 26 that does not branch, thereby branching the flow path and allowing water to flow into the first water discharge flow path 80 and the second water discharge flow path 90.

[0088] Moreover, the lid portion 40 may not have the position maintaining portion 60. For example, the water discharger 1A may have a configuration in which the first lid portion 401 and the second lid portion 403 are provided separately, and the position maintaining portion 60 is not provided.

[0089] Furthermore, in the first embodiment, the position-maintaining unit 60 is formed integrally with the first lid unit 401 and separate from the second lid unit 403, but the position-maintaining unit 60 may be formed integrally with the second lid unit 403 and separate from the first lid unit 401. The position-maintaining unit 60 may also be formed separate from the first lid unit 401 and the second lid unit 403, and assembled using fasteners such as screws. However, it is more preferable that the position-maintaining unit 60 be formed integrally with the first lid unit 401 or the second lid unit 403 so as not to obstruct the water flow in the first water discharge flow path 80.

[0090] Furthermore, the water discharger 1A may be provided with only one position maintaining section 60, or may be provided with two or more position maintaining sections 60. Preferably, the water discharger 1A is provided with two or less position maintaining sections 60.

[0091] Furthermore, although the position-maintaining unit 60 has been shown to have a streamlined shape as an example, the position-maintaining unit 60 may also be a rectangular parallelepiped. However, it is more preferable that the position-maintaining unit 60 has a streamlined shape so as not to disturb the water flow in the first water discharge flow path 80.

[0092] Furthermore, the diameter of the position-maintaining part 60 can be determined arbitrarily so as not to interfere with the water flow in the first water discharge flow path 80 or the second water discharge flow path 90, and so as to limit the movement of the first lid part 401 and the second lid part 403. Furthermore, the diameter of the position-maintaining part 60 does not have to be constant; for example, it may become narrower or wider from the first lid part 401 to the second lid part 403. As described above, the position-maintaining part 60 may be designed into a shape that is less likely to disturb the water flow, based on the dimensions of each component, such as the first water discharge flow path 80, the inlet pipe 81, and the second water discharge flow path 90.

[0093] The second wall portion 513 may be configured as a single member, or may be divided into two or more members. For example, the second wall portion 513 may be divided into one second wall portion 513 that forms the underside of the first water discharge flow path 80, and another second wall portion 513 that forms the upper surface of the second water discharge flow path 90. The third wall portion 515 may also be configured as a single member, or may be divided into two or more members. For example, the third wall portion 515 may be divided into one third wall portion 515 that forms the underside of the second water discharge flow path 90, and another third wall portion 515 that is connected to the bathtub 2.

[0094] Furthermore, each component of the wall 51 may be integrally formed, or may be formed separately. For example, the first wall 511 and one second wall 513 that form the first water discharge flow path 80 may be integrally formed, and the other second wall 513 and third wall 515 that form the second water discharge flow path 90 may be integrally formed separately. With this configuration, the components that form the first water discharge flow path 80 and the components that form the second water discharge flow path 90 may be separable. Also, for example, the second wall 513 and one third wall 515 that form the second water discharge flow path 90 may be integrally formed, and the third wall 515 that connects to the bathtub 2 may be formed separately. With this configuration, the components that form the second water discharge flow path 90 and the components that connect to the bathtub 2 may be separable. [Explanation of symbols]
