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 describes a water discharge device provided with a lid for maintenance of the water discharge flow path. [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, providing an illuminator around the lid prevents the lid from being opened and closed, making it impossible to ensure maintainability of the water discharge flow path.

[0006] In view of the above problems, the present invention aims to provide a water discharge device in which the lid can be easily opened and closed even when a lighting device is provided in the water discharge device, and which ensures the maintainability of the water discharge flow path. [Means for solving the problem]

[0007] To solve the above problem, according to a first aspect of the present invention, there is provided the following water discharge device: This water discharge device includes a first wall portion forming the upper surface of a water discharge flow path having a water discharge outlet that discharges water toward the bathtub, a lid portion that penetrates the first wall portion and is configured to be able to open and close the water discharge flow path, an illuminator that is provided above the first wall portion and is located closer to the water discharge outlet than the lid portion, and a cord member that is connected to the illuminator and is located in a position that does not overlap with the lid portion in a plan view.

[0008] With this configuration, compared to when the cord member is positioned so that it overlaps with the lid portion in a planar view, even when the lighting device is installed on the water discharge device, the lid portion can be opened and closed easily, ensuring maintainability of the water discharge flow path.

[0009] In addition, in the water-discharging device of the second aspect of the present invention, the lighting device is longer in one of the left-right directions than the lid portion in the left-right direction perpendicular to the water-discharging direction when viewed in a plane, and the cord member is connected to one end of the lighting device on the side that is longer in the left-right direction than the lid portion.

[0010] With this configuration, compared to when the cord member is connected to the central part of the illuminator in the left-right direction, the cord member is provided in a position that does not overlap with the area between the lid portion and the illuminator, making it easier to open and close the lid portion and also ensuring maintainability of the water discharge flow path.

[0011] Moreover, in the water discharge device according to the third aspect of the present invention, the cord member is connected to the side surface of the illuminator that faces the lid portion.

[0012] With this configuration, the storage space for the cord member is not increased compared to when the cord member is connected to the side surface of the lighting device that does not face the lid, and storage efficiency is improved.

[0013] In addition, in the water-dispensing device according to the fourth aspect of the present invention, at least a part of the illuminator is arranged at a position equal to or lower than the lid portion in the height direction, and the cord member is arranged at a position equal to or lower than the lid portion in the height direction.

[0014] According to this configuration, the lid portion is positioned at the same height as or higher than the cord member, making it easier to open and close the lid portion and further ensuring ease of maintenance of the water discharge flow path.

[0015] In addition, in the water-discharging device according to the fifth aspect of the present invention, the water-discharging flow path has a storage section that stores water flowing in from the upstream side as stored water, and a throttle flow path that sends the stored water in the storage section to the water outlet, the lid section is shorter than at least a portion of the storage section in the left-right direction, the cord member is positioned so as not to overlap with the storage section in a planar view, and a portion of the cord member extends downwardly below the storage section.

[0016] With this configuration, the cord member is positioned so that it overlaps the top of the storage section, and compared to when it needs to be extended downward to avoid the storage section, the storage space for the cord member does not increase, improving storage efficiency.

[0017] In addition, in the water-discharging device according to the sixth aspect of the present invention, the side surfaces on both sides of the water-discharging flow path in the left and right directions are formed in an arc-like shape that curves in a concave direction opposite the water-discharging direction, and the lid portion has a front portion located on the side of the water-discharging outlet and a rear portion located on the opposite side from the front portion, and when viewed in a plane, the length of the front portion is the same as the length of the rear portion in the front-to-rear direction, and the cord member extends downward on the rear portion side from the front portion of the lid portion.

[0018] According to this configuration, by positioning the cord member so as to avoid the water discharge flow path, the storage space for the cord member does not increase compared to when the cord is extended downward from the front side of the lid portion, and storage efficiency is improved. [Effects of the Invention]

[0019] According to the water discharge device of the present invention, even if an illumination device is provided in the water discharge device, the lid portion can be easily opened and closed, and the ease of maintenance of the water discharge flow path can be ensured.

[Figure 7] 6 is a cross-sectional view of the water discharger shown in FIG. 5 taken along the arrow BB. DETAILED DESCRIPTION OF THE INVENTION

[0021] 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.

[0022] <Embodiment> First, a bathtub apparatus 3 to which a water discharger 1 according to an embodiment of the present invention is applied will be described.

[0023] <Overall structure> FIG. 1 is a schematic perspective view showing a bathtub apparatus 3 to which a water discharger 1 according to an embodiment of the present invention is applied, and FIG. 2 is a top view of the bathtub apparatus 3 shown in FIG.

[0024] As shown in Figures 1 and 2, a bathtub apparatus 3 to which a water discharger 1 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 1 is installed in the bathtub 2. The bathtub 2 stores water (including hot water) supplied from the water supply unit 10. The water discharger 1 is formed with a water outlet 4 that discharges water horizontally and in a band shape into the bathtub 2.

[0025] 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 end (rim) 2c that is connected to the top of the vertical wall 2b and forms the top surface of the bathtub 2. The water discharger 1 is installed on the inner edge of the upper end 2c of the bathtub 2.

[0026] For ease of explanation, as shown in the figure, in a plan view, the direction parallel to the water spouting direction of the water spouting device 1 is referred to as the front-to-rear direction, the direction in which the water spouting device 1 is installed in the bathtub 2 is referred to as the rear, and the direction in which the water spouting device 1 is not installed is referred to as the front. Also, in a plan view, the direction perpendicular to the front-to-rear direction is referred to as the left-to-right direction, and when looking at the water spout 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, and the vertically upward is referred to as the upward direction and the vertically downward is referred to as the downward direction. The front-to-rear direction, left-to-right direction, and height direction are perpendicular to each other. These directions are not limited to being strictly perpendicular, but also include cases in which they are approximately perpendicular. These directional notations do not limit the usage orientation of the water spouting device 1, and the water spouting device 1 can be used in any orientation depending on the application.

[0027] 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 discharge section 18 is formed on the vertical wall 2b. The 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 discharge port 4 is located between the backrest section 7 and the pillow section 8, and discharges water toward the bathtub 2, particularly toward the shoulders of the bather H in a bathing position.

[0028] 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.

[0029] 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 discharger 1 is installed.

[0030] 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.

[0031] 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.

[0032] 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 able to operate 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 1.

[0033] The operating unit 30 is operated by the bather H. The operating unit 30 is installed on a wall in the bathroom so that the bather H can turn the water discharge device 1 on and off. 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.

[0034] 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 1 can discharge a large amount of shoulder-water water from the discharge port 4 using a relatively small pump 11.

[0035] 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.

[0036] 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.

[0037] 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 1 discharges the water supplied from the rising pipe 26 into the bathtub 2. The tip of the rising pipe 26 on the water discharger 1 side branches into multiple parts.

[0038] <Detailed configuration of water discharge device 1> FIG. 5 is a side cross-sectional view of the water discharger 1 shown in FIG. 1 with the pillow part 8 removed.

[0039] As shown in FIG. 5, the water discharger 1 includes a pillow rest portion 50, a wall portion 51, a lid portion 40, and an illuminator 60.

[0040] The pillow rest 50 is provided on the top surface of the water discharger 1. The pillow rest 50 is provided over the entire range in the front-to-rear direction on the top surface of the water discharger 1, but may also be provided over a portion of the range from the front end of the front side facing the inside of the bathtub 2 to the rear side. The pillow rest 50 is also provided so that the top of the water discharger 1 can be opened and closed.

[0041] Wall 51 is a molded resin product, and is formed by assembling first wall 511 and second wall 513 with fasteners such as screws. Note that first wall 511 and second wall 513 may be formed integrally. A plurality of water conduits 53 protruding downward are provided at intervals in the left-right direction at the bottom of second wall 513. Water conduits 53 are inserted through bathtub 2, and the aforementioned riser pipe 26 is connected to their ends. Water intake 81 is formed inside water conduit 53, and bathwater is pumped from pump 11 through riser pipe 26.

[0042] The first wall portion 511 has a horizontally long, slit-shaped water outlet 4 formed in its front portion, and a water discharge flow path 80 connecting the water intake 81 and the water outlet 4 is formed inside it. The water discharge flow path 80 is formed horizontally long so that the width of its cross section in the left-right direction of the flow path is greater than the flow path height. The first wall portion 511 forms the upper surface of the water discharge flow path 80, and the second wall portion 513 forms the lower surface of the water discharge flow path 80. The water discharge flow path 80 has a storage portion 803, a throttle flow path 805, and the water outlet 4. Water flowing in from the water intake 81 is temporarily stored in the storage portion 803 as stored water. The throttle flow path 805 is formed so that the flow path height of the water discharge flow path 80 is smaller than that of the storage portion 803. The stored water in the storage portion 803 is sent out to the water outlet 4 through the throttle flow path 805. Specifically, the stored water is throttled as it passes through the throttle flow path 805, increasing its flow rate, and the water is forcefully discharged from the water discharge port 4 as a discharged water flow W.

[0043] The lid portion 40 has a front portion 401 located on the side of the spout 4 in the front-to-rear direction parallel to the water discharge direction when viewed from above, and a rear portion 403 located on the opposite side from the front portion 401. In other words, the front portion 401 is the front region of the lid portion 40. The rear portion 403 is the rear region of the lid portion 40. In the front-to-rear direction, the length of the front portion 401 is the same as the length of the rear portion 403.

[0044] The lid portion 40 is provided so as to penetrate the first wall portion 511. The lid portion 40 also forms part of the upper surface of the water discharge flow path 80. Specifically, the lid portion 40 forms part of the upper surface (ceiling wall) of the storage portion 803. The left-right dimension of the lid portion 40 is preferably at least half the left-right dimension of the water discharge flow path 80, in order to sufficiently improve the maintainability of the water discharge flow path 80.

[0045] The lid portion 40 is configured to be able to open and close the water discharge flow path 80 while the water discharge device 1 remains attached to the bathtub 2. By opening or removing the lid portion 40, an opening that communicates with the water discharge flow path 80 is formed. This makes it easy to perform maintenance such as cleaning up to the rear of the water discharge flow path 80 while the water discharge device 1 remains attached to the bathtub 2. Note that being openable and closable also includes being detachable.

[0046] The lid portion 40 extends in the horizontal direction. Therefore, by opening or removing the lid portion 40, the maintenance of the horizontally long water discharge flow path 80 can be ensured.

[0047] The illuminator 60 is provided on the upper part of the first wall portion 511, and is located closer to the spout 4 (forward) than the lid portion 40. The illuminator 60 has an LED light emitter 67 and a housing case 65. The housing case 65 is waterproof and translucent, and covers the light emitter 67. The housing case 65 may also form part of the ceiling wall of the throttle flow path 805, or part of the ceiling wall of the spout 4. At least part of the illuminator 60 is provided at the same height as the lid portion 40 or lower than the lid portion 40.

[0048] The illuminator 60 illuminates the water flow W discharged from the water outlet 4. Specifically, the light L emitted from the illuminator 60 toward the bathtub 2 directly illuminates the water flow W discharged from the water outlet 4.

[0049] The second wall portion 513 and the first wall portion 511 may be formed as separate bodies, with a waterproof packing provided between them. Also, a packing may be provided between the accommodating case 65 and the first wall portion 511.

[0050] FIG. 6 is a schematic view of the water discharger 1 shown in FIG. 5, with the pillow rest portion 50 removed, viewed from the direction A.

[0051] As shown in FIG. 6, the water discharger 1 includes a cord member 61 and a cord hole 63 in addition to the lid portion 40, wall portion 51, and illuminator 60 described above.

[0052] The cord member 61 is a power line for supplying power to the illuminator 60 from a power supply unit (not shown) outside the water discharger 1. The cord member 61 is provided at a position where it does not overlap with the lid portion 40 in a plan view. That is, the cord member 61 is provided at a position different from the lid portion 40 in a plan view. This configuration prevents the cord member 61 from getting caught on the lid portion 40 when the lid portion 40 is opened or closed, and prevents the cord member 61 from interfering with the opening and closing of the lid portion 40. Furthermore, the cord member 61 is connected to the side surface of the illuminator 60 facing the lid portion 40. That is, the cord member 61 is connected to the side surface of the illuminator 60 on the rear side.

[0053] The cord hole 63 is a hole formed through the wall portion 51. A cord member 61 is inserted into the cord hole 63. At least a part of the cord member 61 extends from the cord hole 63 downward from the water discharger 1.

[0054] The cord member 61 is arranged at a height position equal to or lower than the lid portion 40. Specifically, the cord member 61 is connected to the illuminator 60 at a height position equal to or lower than the lid portion 40, and does not extend upward from the lid portion 40, but extends downward from the cord hole 63. In other words, the lid portion 40 is arranged at a height position equal to or higher than the cord member 61. With this configuration, when the lid portion 40 is opened or closed from above, the cord member 61 does not interfere with the opening and closing of the lid portion 40, making it easier to open and close the lid portion 40 and ensuring maintainability of the water discharge flow path 80.

[0055] The illuminator 60 is longer than the lid 40 in the left-right direction perpendicular to the water discharge direction when viewed from above. That is, the illuminator 60 is longer leftward than the left side surface of the lid 40, or longer rightward than the right side surface of the lid 40, or longer left-right than the lid 40. Here, the cord member 61 is connected to one end of the illuminator 60 on the side that is longer left-right than the lid 40. That is, the cord member 61 is provided in a position different from the area between the lid 40 and the illuminator 60.

[0056] FIG. 7 is a cross-sectional view of the water discharger 1 shown in FIG. 5 taken along the arrow BB.

[0057] 7, a part of the cord member 61 extends from the cord hole 63 downward below the storage portion 803. Furthermore, the cord member 61 is provided at a position that does not overlap with the storage portion 803 in a plan view.

[0058] The left and right side surfaces of the water discharge flow path 80 are formed in an arc-like shape that curves in a direction opposite to the water discharge direction (rearward). The rear of the wall portion 51 is formed in a rectangular shape with rounded corners. Here, the cord member 61 extends downward from the front portion 401 of the lid portion 40 toward the rear portion 403. Specifically, the cord hole 63 is formed in the area where there is a gap between the water discharge flow path 80 at the rear of the water discharger 1 and the outer edge of the wall portion 51, and the cord member 61 extends downward from the cord hole.

[0059] The above-described lid portion 40 is shorter in the left-right direction than at least a part of the storage portion 803. That is, the left-right dimension of the lid portion 40 is smaller than the left-right dimension of the storage portion 803.

[0060] <Action and effect> As described above, the water discharge device 1 of this embodiment comprises a first wall portion 511 that forms the upper surface of a water discharge flow path 80 having a water discharge outlet 4 that discharges water toward the bathtub 2, a lid portion 40 that is provided to penetrate the first wall portion 511 and is configured to be able to open and close the water discharge flow path 80, an illuminator 60 that is provided on the upper part of the first wall portion 511 and is located closer to the water discharge outlet 4 than the lid portion 40, and a cord member 61 that is connected to the illuminator 60 and is located in a position that does not overlap with the lid portion 40 in a planar view.

[0061] With this configuration, even when the lighting device 60 is installed on the water discharge device 1, the lid portion 40 can be opened and closed more easily than when the cord member 61 is installed in a position that overlaps with the lid portion 40 in a planar view, ensuring maintainability of the water discharge flow path 80.

[0062] In addition, in the water discharge device 1, the lighting device 60 is longer in one direction in the left-right direction than the lid portion 40 in the left-right direction perpendicular to the water discharge direction when viewed in a plane, and the cord member 61 is connected to one end of the lighting device 60 on the side that is longer in the left-right direction than the lid portion 40.

[0063] With this configuration, compared to when the cord member 61 is connected to the central part of the left-right direction of the illuminator 60, the cord member 61 is provided in a position that does not overlap with the area between the lid portion 40 and the illuminator 60, making it easier to open and close the lid portion 40 and ensuring maintainability of the water discharge flow path 80.

[0064] In addition, in the water discharger 1, the cord member 61 is connected to the side of the illuminator 60 that faces the lid portion 40.

[0065] According to this configuration, the storage space for the cord member 61 does not increase compared to when the cord member 61 is connected to the side of the illuminator 60 that does not face the lid portion 40, and storage efficiency is improved.

[0066] In addition, in the water discharge device 1, at least a part of the lighting device 60 is arranged at a position equal to or lower than the lid portion 40 in the height direction, and the cord member 61 is arranged at a position equal to or lower than the lid portion 40 in the height direction.

[0067] According to this configuration, the lid portion 40 is positioned at the same height as or higher than the cord member 61, making it easy to open and close the lid portion 40 and ensuring ease of maintenance of the water discharge flow path 80.

[0068] In addition, in the water discharge device 1, the water discharge flow path 80 has a storage section 803 that stores water flowing in from the upstream side as stored water, and a throttle flow path 805 that sends the stored water in the storage section 803 to the water discharge outlet 4, the lid section 40 is shorter in the left-right direction than at least a part of the storage section 803, the cord member 61 is arranged in a position that does not overlap with the storage section 803 in a planar view, and a part of the cord member 61 extends downward below the storage section 803.

[0069] According to this configuration, the cord member 61 is provided at a position overlapping the upper part of the storage section 803, and the storage space for the cord member 61 is not increased, and storage efficiency is improved, compared to when the cord member 61 needs to be extended downward to avoid the storage section 803.

[0070] In addition, in the water discharge device 1, the side surfaces on both the left and right sides of the water discharge flow path 80 are formed in an arc shape that curves so as to be concave in the direction opposite to the water discharge direction, and the lid portion 40 has a front portion 401 located on the water discharge outlet 4 side and a rear portion 403 located on the opposite side from the front portion 401, and when viewed in a plane, the length of the front portion 401 is the same as the length of the rear portion 403 in the front-to-back direction, and the cord member 61 extends downward on the rear portion 403 side from the front portion 401 of the lid portion 40.

[0071] According to this configuration, by positioning the cord member 61 so as to avoid the water discharge flow path 80, the storage space for the cord member 61 does not increase compared to when the cord member 61 is extended downward from the front side of the lid portion 40, and storage efficiency is improved.

[0072] <Modification> 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.

[0073] For example, the illuminator 60 is longer in one of the left and right directions than the lid portion 40 in the example described above, but the illuminator 60 may include a configuration that is shorter in the left and right direction than the lid portion 40.

[0074] Furthermore, although the configuration in which the cord member 61 is connected to the side surface of the illuminator 60 facing the lid portion 40 has been given as an example, the cord member 61 may be connected to the side surfaces of the illuminator 60 in the left and right directions.

[0075] Furthermore, the code member 61 is not limited to a power line, but may be a communication line for communicating with the outside.

[0076] In addition, although the configuration in which lid portion 40 is shorter than at least a portion of storage portion 803 in the left-right direction has been given as an example, lid portion 40 may be longer than storage portion 803 in the left-right direction. Furthermore, lid portion 40 may form a portion of the ceiling wall of storage portion 803 and most of the rear side wall at the top of storage portion 803. Furthermore, the left-right dimension of lid portion 40 may be half or less of the lateral dimension of water discharge flow path 80.

[0077] Moreover, the code member 61 may be provided at a position overlapping the area between the lid portion 40 and the illuminator 60 in a plan view. The code member 61 may also be located at a position overlapping the storage portion 803 in a plan view.

[0078] Furthermore, the cord member 61 may be connected to a side of the illuminator 60 other than the side facing the lid 40. That is, the cord member 61 may be connected to a side of the illuminator 60 on the front side or on the left or right side.

[0079] In addition, although the configuration in which the left and right side surfaces of the water discharge flow path 80 are formed in an arc shape that curves in a direction opposite to the water discharge direction (rearward) has been shown as an example, the left and right side surfaces of the water discharge flow path 80 may also be formed in a straight line. For example, the left and right side surfaces of the water discharge flow path 80 may have a rectangular structure in a plan view.

[0080] In addition, although the above example shows a configuration in which at least a portion of the illuminator 60 is provided at the same position as or lower than the lid portion 40 in the height direction, at least a portion of the illuminator 60 may be provided at a higher position than the lid portion 40. In addition, the above example shows a configuration in which at least a portion of the cord member 61 is provided at the same position as or lower than the lid portion 40 in the height direction, but at least a portion of the cord member 61 may be provided at a higher position than the lid portion 40.

[0081] In addition, although the cord member 61 has been configured to extend downward from the storage section 803 as an example, the cord member 61 may extend rearward instead of downward and be connected to the power supply section. In this case, the cord hole 63 may be provided in, for example, the pillow rest section 50. In addition, the cord member 61 has been configured to extend downward from the front section 401 of the lid section 40 toward the rear section 403 as an example, but it may also extend downward from the front section 401 side of the lid section 40.
