Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the urinal described in Patent Document 1, the water discharge port of the urinal spreader opens downward. The washing water flowing out from the water discharge port spreads in the left - right direction on the inner surface of the back side of the urinal bowl (that is, the surface facing the user) only by the momentum of the flow spread by the urinal spreader. Also, the washing water flowing out from the water discharge port spreads in the part below the water discharge port on the inner surface of the back side of the urinal bowl, and the upper end part of the inner surface of the back side cannot be washed.

[0006] In view of the above circumstances, an object of the present disclosure is to provide a urinal capable of flowing washing water over a wider range with respect to the inner surface of the bowl.

Means for Solving the Problems

[0007] A urinal according to one aspect of the present disclosure includes a bowl recessed rearward, and a water discharge portion provided at an upper portion of the bowl for discharging washing water. The inner surface of the bowl has an upper surface facing downward and a back surface facing forward and forming a corner portion with the upper surface. The water discharge portion has a discharge port for discharging the washing water. The discharge port opens toward the corner portion.

Effect of the Invention

[0008] The urinal according to one aspect of the present disclosure can flow the washing water over a wider range with respect to the inner surface of the bowl.

Mode for Carrying Out the Invention

[0010] The urinal according to an embodiment of the present disclosure will be described in detail with reference to the drawings. Each configuration described below is merely an example of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications can be made according to the design and the like without departing from the technical idea of the present disclosure.

[0011] (One Embodiment) 1. Overview As shown in FIGS. 1 and 2, a urinal 1 according to an embodiment of the present disclosure includes a bowl 2 recessed rearward, and a water discharge part 3 provided above the bowl 2 for discharging washing water W1. The inner surface of the bowl 2 has an upper surface 20 facing downward and a back surface 21 facing forward and forming a corner part 22 between the upper surface 20. The water discharge part 3 has a water discharge port 30 for discharging the washing water W1. The water discharge port 30 opens toward the corner part 22.

[0012] In the urinal 1 of an embodiment having the above configuration, the washing water W1 can be discharged from the water discharge port 30 of the water discharge part 3 toward the corner part 22 between the upper surface 20 and the back surface 21 of the inner surface of the bowl. The washing water W1 discharged to the corner part 22 is not likely to immediately fall due to the surface tension generated between the washing water W1 and the corner part 22, and is likely to spread in the extending direction of the corner part 22, that is, in the left - right direction. Therefore, in the urinal 1 of an embodiment, since the washing water W1 can be supplied to a wider range in the left - right direction from the upper end with respect to the back surface 21 of the bowl 2, the washing water W1 can be made to flow over a wider range of the inner surface of the bowl.

[0013] 2. Details Subsequently, the urinal 1 of an embodiment shown in FIGS. 1 to 5 will be described in more detail. The urinal 1 is a urinal 1 installed on the floor along a wall. In the following description, the side where the urinal 1 is located with respect to the wall on which the urinal 1 is installed is defined as the front, the opposite side as the rear, and the direction orthogonal to the front - rear direction in a plan view is defined as the left - right direction, and each component will be described in detail.

[0014] The urinal 1 is formed using synthetic resin. Note that the urinal 1 may be formed of other materials such as pottery.

[0015] As shown in FIGS. 1 and 2, the urinal 1 includes a bowl 2 recessed rearward, and a water discharge part 3 provided above the bowl 2 for discharging washing water W1. In the present embodiment, the urinal 1 further includes a mounting member 4 for mounting the water discharge part 3 to the bowl 2, and a pipe joint 5 for connecting the water discharge part 3 and a water supply source.

[0016] 2-1. Bowl The bowl 2 is configured to receive the urine of the user. A drainage part (not shown) configured to discharge urine, washing water W1, etc. that have flowed down the inner surface of the bowl 2 is connected to the bottom part of the bowl 2. The bowl 2 is formed using synthetic resin. Note that the bowl 2 may be formed of other materials such as pottery.

[0017] As a whole, the bowl 2 is formed long in the vertical direction. The bowl 2 has an upper surface 20 facing downward and a back surface 21 facing forward and forming a corner part 22 between the upper surface 20. The bowl 2 further has a bottom surface (not shown) facing upward and a pair of side surfaces 23 facing inward in the left-right direction.

[0018] The upper surface 20 is inclined with respect to the horizontal plane such that the rear part is positioned lower. The angle α of the upper surface 20 with respect to the horizontal plane is approximately 15 degrees. The angle α is preferably 10 degrees or more and 20 degrees or less, but can be set as appropriate.

[0019] The cross-sectional shape of the back surface 21 orthogonal to the vertical direction is an arc shape convex rearward. Therefore, the rear end of the upper surface 20 is an arc shape convex rearward. An arc-shaped corner part 22 convex rearward is formed between the upper surface 20 and the back surface 21. The corner part 22 extends in the horizontal direction.

[0020] A water spraying part 3 is provided on the upper surface 20. More specifically, the water spraying part 3 is provided at the central part in the left-right direction of the upper surface 20 and at a part separated forward from the rear end. A through hole 200 through which a part of the water spraying part 3 (specifically, a cylindrical part 33 described later in detail) is inserted is provided on the upper surface 20.

[0021] 2-2. Water Spraying Part The water spraying part 3 is configured to spray the washing water W1 toward the inner surface of the bowl 2. The water spraying part 3 is formed using synthetic resin. Hereinafter, with respect to the water spraying part 3, with the state of being attached to the bowl 2 as a reference, the vertical, front-rear, and left-right directions are defined, and each component will be described.

[0022] As shown in FIGS. 2 to 4, the water discharging portion 3 includes an inlet 31 into which the washing water W1 flows, an outlet 30 for discharging the washing water W1 that has flowed into the inlet 31, and a water guiding path 32 that communicates the inlet 31 and the outlet 30.

[0023] The water discharging portion 3 includes a cylindrical tube portion 33 and a hollow main body portion 34 provided integrally with the tube portion 33. The inlet 31 and a part of the water guiding path 32 are provided in the tube portion 33, and the remaining part of the water guiding path 32 and the outlet 30 are provided in the main body portion 34.

[0024] A part of the upper surface 340 of the main body portion 34 protrudes from the tube portion 33. A pair of screw fixing holes 341 for fixing the water discharging portion 3 to the bowl 2 are provided in another part of the upper surface 340. A pair of screw fixing holes 341 are provided at a location in the main body portion 34 that does not overlap with the water guiding path 32 in a plan view. The pair of screw fixing holes 341 are holes that open only upward and do not penetrate the main body portion 34 in the vertical direction.

[0025] The opening at one end (specifically, the upper end) in the axial direction of the tube portion 33 is the inlet 31. Among the inner space of the tube portion 33, the portion downstream of the inlet 31 is a first water guiding path 320 that is a part of the water guiding path 32 (specifically, the upstream portion).

[0026] The inner space of the main body portion 34 is a second water guiding path 321 that is the remaining part of the water guiding path 32 (specifically, the downstream portion). The outlet 30 is provided at the rear end portion of the main body portion 34.

[0027] The water discharging portion 3 includes a wall surface 35 that surrounds the second water guiding path 321 of the water guiding path 32. In the present embodiment, the second water guiding path 321 is fan-shaped in a plan view. The second water guiding path 321 has a larger flow passage area in the portion closer to the outlet 30.

[0028] The wall surface 35 includes an inner upper surface 350 located above the second water guiding path 321, an inner lower surface 351 located below the second water guiding path 321, a pair of inner side surfaces 352 located on the left and right of the second water guiding path 321, and an inner front surface 353 located in front of the second water guiding path 321.

[0029] Each of the inner upper surface 350 and the inner lower surface 351 is fan-shaped in plan view, and the portion closer to the discharge port 30 is longer in the left-right direction. The inner upper surface 350 and the inner lower surface 351 are farther apart in the vertical direction at the portion closer to the discharge port 30. The inner lower surface 351 extends rearward from the inner upper surface 350, and the rear end portion (in other words, the downstream end portion) of the inner lower surface 351 is located rearward of the inner upper surface 350.

[0030] An opening 354 connected to the first water conduit 320 is provided in the front portion of the inner upper surface 350. A rib 36 in the form of a convex strip extending toward the discharge port 30 is provided on the inner lower surface 351. The inner lower surface 351 is inclined with respect to the horizontal plane so that the rear portion is located lower.

[0031] The angle β of the inner lower surface 351 with respect to the upper surface 20 is approximately 10 degrees. The angle β is preferably 5 degrees or more and 20 degrees or less, but can be set as appropriate.

[0032] The rib 36 is located at the center in the left-right direction on the inner lower surface 351. The rib 36 is located over the entire length from the front end to the rear end (that is, the downstream end) of the inner lower surface 351. The rib 36 extends in a straight line. The cross-sectional shape perpendicular to the longitudinal direction of the rib 36 is semi-circular.

[0033] The rib 36 is located opposite to the opening 354 of the inner upper surface 350. The rib 36 is located directly below the center of the opening 354. Therefore, the washing water falling from the opening 354 is likely to be affected by the rectifying effect of the rib 36.

[0034] Each of the pair of inner side surfaces 352 is flat. The pair of inner side surfaces 352 are provided such that the interval between the pair of inner side surfaces 352 becomes wider at the rear portion (the side closer to the discharge port 30). The pair of inner side surfaces 352 extend rearward from the inner upper surface 350, and the rear end portions (in other words, the downstream end portions) of the pair of inner side surfaces 352 are located rearward of the inner upper surface 350.

[0035] The space surrounded by the inner upper surface 350, the inner lower surface 351, and the pair of inner side surfaces 352 is the second water conduit 321. The discharge port 30 is a portion surrounded by the rear end portion (the downstream end portion) of the inner lower surface 351 and the rear end portion (the downstream end portion) of the pair of inner side surfaces 352, and is located behind the inner upper surface 350. The discharge port 30 opens rearward and upward. Therefore, the discharge port 30 opens toward the corner portion 22 between the upper surface 20 and the back surface 21 of the bowl 2. The discharge port 30 further opens toward the rear end portion of the upper surface 20 of the bowl 2 (that is, the portion adjacent to the corner portion 22).

[0036] The water discharge portion 3 is attached to the upper surface 20 such that the upper surface 340 of the main body portion 34 is along the upper surface 20 of the bowl 2 and the cylindrical portion 33 is inserted into the through hole 200 of the upper surface 20 of the bowl 2. The water discharge portion 3 is attached to the upper surface 20 such that a part of the upper surface 20 is located between the discharge port 30 of the water discharge portion 3 and the corner portion 22.

[0037] 2-3. Mounting member As shown in FIG. 2, the mounting member 4 has a flat plate-shaped first mounting portion 40 parallel to the upper surface 20 of the bowl 2, and a second mounting portion 41 rising upward from one end (specifically, the upper end) of the first mounting portion 40.

[0038] The first mounting portion 40 is provided with an insertion hole 400 through which the cylindrical portion 33 of the water discharge portion 3 is inserted, and two screw insertion holes (not shown) through which screws for fixing the water discharge portion 3 to the bowl 2 are inserted. Each of the insertion hole 400 and the two screw insertion holes penetrates the first mounting portion 40 in the vertical direction.

[0039] The mounting member 4 is installed above the bowl 2 on the back side of the bowl 2. The mounting member 4 is arranged such that the first mounting portion 40 is along the upper surface 20 of the bowl 2 on the back side of the bowl 2.

[0040] The water discharging part 3 is fixed to the bowl 2 and the mounting member 4 by driving screws from the back side of the bowl 2 into the two screw insertion holes and the two screw fixing holes 341 with the cylindrical part 33 of the water discharging part 3 inserted into the through hole 200 of the bowl 2 and the insertion hole 400 of the mounting member 4. In the state where the water discharging part 3 is fixed to the bowl 2 and the mounting member 4, the upper surface 340 of the main body part 34 of the water discharging part 3 contacts the upper surface of the bowl 2.

[0041] 2-4. Pipe Joint The pipe joint 5 is connected to the cylindrical part 33 of the water discharging part 3. The cylindrical part 33 and the pipe joint 5 are fixed to each other by connecting a metal locking tool 6.

[0042] The pipe joint 5 has an L-shaped water guiding path 50 inside. A water supply hose or a water supply pipe connected to a water supply source is connected to the pipe joint 5, and the cleaning water from the water supply source is supplied.

[0043] 3. Cleaning of the Bowl Subsequently, the cleaning of the inner surface of the bowl 2 in the urinal 1 of the present embodiment will be described.

[0044] In the urinal 1 of the present embodiment, as shown in FIG. 5, the cleaning water W1 flowing into the inlet 31 of the water discharging part 3 from the water supply source is guided by the fan-shaped second water guiding path 321 in plan view of the water guiding path 32, and the cleaning water W1 is discharged in a fan shape in plan view from the discharge port 30.

[0045] Here, in the urinal 1 of the present embodiment, as shown in FIG. 2, the discharge port 30 opens upward and rearward and is located slightly away from the corner part 22. Therefore, the cleaning water W1 discharged from the discharge port 30 includes a flow toward the upper surface 20 of the bowl 2, a flow toward the corner part 22 of the bowl 2, and a flow toward the back surface 21 of the bowl 2.

[0046] The washing water W1 directed from the water discharge port 30 toward the upper surface 20 is suppressed from immediately falling from the upper surface 20 due to the surface tension generated between the upper surface 20, and as shown in FIG. 5, it moves rearward while spreading in the left - right direction along the upper surface 20 and flows into the corner portion 22. Then, the washing water W1 that has flowed into the corner portion 22 is suppressed from immediately falling from the corner portion 22 due to the surface tension generated between the corner portion 22, and it spreads in the left - right direction along the corner portion 22 and then flows into the lower back surface 21.

[0047] Also, the washing water W1 directed from the water discharge port 30 toward the corner portion 22 is suppressed from immediately falling from the corner portion 22 due to the surface tension generated between the corner portion 22, and it spreads in the left - right direction along the corner portion 22 and then flows into the lower back surface 21.

[0048] Also, the washing water W1 directed from the water discharge port 30 toward the back surface 21 flows down while spreading in the left - right direction along the back surface 21 starting from the contact point with the back surface 21.

[0049] By flowing the washing water W1 as described above, in the urinal 1 of the present embodiment, the washing water W1 is supplied to a wider range in the left - right direction from the upper end to the back surface 21 of the bowl 2, and further, the washing water W1 flows down while spreading in the left - right direction along the back surface 21 from the upper end of the back surface 21. Thus, in the urinal 1 of the present embodiment, the washing water W1 can be flowed over a wider range in the vertical and horizontal directions with respect to the inner surface (especially the back surface 21) of the bowl 2.

[0050] 4. Operational effects In the urinal 1 of the present embodiment described above, the washing water W1 discharged from the water discharge portion 3 can be spread in the left - right direction by utilizing the upper surface 20 and the corner portion 22 of the bowl 2. Therefore, in the urinal 1 of the present embodiment, compared with the case where all of the washing water W1 is discharged from the water discharge port 30 of the water discharge portion 3 toward the back surface 21 of the bowl 2, the washing water can be flowed over a wider range in the vertical and horizontal directions with respect to the back surface 21.

[0051] In addition, in the urinal 1 of the present embodiment, since the washing water W1 can be spread in the left - right direction by utilizing the upper surface 20 and the corner portion 22 of the bowl 2, the water - discharging portion 3 can be provided compactly in the left - right direction.

[0052] Also, in the urinal 1 of the present embodiment, since the rib 36 extending to the discharge port 30 is provided at the central portion in the left - right direction of the inner lower surface 351 of the water - discharging portion 3, it is easy to divide the washing water W1 received on the inner lower surface 351 into left and right around the rib 36. Therefore, in the urinal 1 of the present embodiment, due to the rectifying effect of the rib 36, it is easy to form a flow along the pair of left - right inner side surfaces 352, and it is easy to spread the washing water W1 in the left - right direction.

[0053] Also, in the urinal 1 of the present embodiment, since the water droplets of the washing water W1 remaining on the inner lower surface 351 of the water - discharging portion 3 can easily flow along the rib 36, the discharge position of the remaining water droplets is likely to be stable.

[0054] Also, in the urinal 1 of the present embodiment, since the water - discharging portion 3 has a water - guiding path (second water - guiding path 321) in a fan - shape in plan view, it is easy to spread the washing water W1 in the left - right direction at the upper surface 20 and the corner portion 22 of the bowl 2.

[0055] Also, in the urinal 1 of the present embodiment, since the upper surface 20 of the bowl 2 is inclined by about 15 degrees with respect to the horizontal plane such that the portion closer to the corner portion 22 is located lower, the washing water W1 easily flows along the upper surface 20 and into the corner portion 22.

[0056] Also, in the urinal 1 of the present embodiment, since the angle of the inner lower surface 351 with respect to the upper surface 20 of the bowl 2 is 5 degrees or more and 20 degrees or less, the washing water W1 discharged along the inner lower surface 351 does not easily fall immediately when hitting the upper surface 20 and easily flows along the upper surface 20.

[0057] Also, in the urinal 1 of the present embodiment, since the discharge port 30 of the water discharge part 3 is located adjacent to the corner part 22 of the bowl 2, the amount of water directly heading from the discharge port 30 to the back surface 21 of the bowl 2 can be suppressed. Therefore, in the urinal 1 of the present embodiment, most of the cleaning water W1 discharged from the discharge port 30 can be easily spread in the left - right direction by utilizing the upper surface 20 and the corner part 22 of the bowl 2.

[0058] (Modification example) Subsequently, a modification example of the urinal 1 of the above - described embodiment will be described. Note that each of the following modification examples can be combined as appropriate.

[0059] The water discharge part 3 does not necessarily have to be provided on the upper surface 20 such that a part of the upper surface 20 of the bowl 2 is located between the discharge port 30 and the corner part 22. For example, the discharge port 30 may be provided so as not to open upward but only to open rearward, and the cleaning water W1 discharged from the discharge port 30 may hit the corner part 22 without hitting the upper surface 20. Also in this case, due to the surface tension generated between the discharge port 30 and the corner part 22, the cleaning water W1 can be easily spread in the left - right direction.

[0060] Also, the upper surface 20 does not necessarily have to be inclined with respect to the horizontal plane such that the portion closer to the back surface 21 is located lower, and it may be provided parallel to the horizontal plane.

[0061] The second water channel 321 of the water channel 32 does not have to be limited to a fan - shaped in plan view, and any shape that can discharge the cleaning water W1 in a direction spreading in the left - right direction with respect to the corner part 22 is acceptable. For example, the second water channel 321 may be a water channel extending linearly, and the opening direction of the discharge port 30 may be provided so as not to be orthogonal to the corner part 22 but to be inclined.

[0062] The inner lower surface 351 of the water discharge part 3 does not necessarily have to be provided with ribbed ridges 36.

[0063] The water discharge part 3 does not necessarily have to be provided on the upper surface 20, and it may be provided on the bowl 2 such that a gap is formed between the upper surface 340 of the main body part 34 of the water discharge part 3 and the upper surface 20 of the bowl 2.

[0064] (Summary) As described above in one embodiment and its modification, the urinal (1) of the first aspect has the following configuration.

[0065] That is, the urinal (1) of the first aspect includes a bowl (2) recessed rearward, and a water discharge part (3) provided above the bowl (2) for discharging washing water (W1). The inner surface of the bowl (2) has an upper surface (20) facing downward and a back surface (21) facing forward and forming a corner part (22) between the upper surface (20). The water discharge part (3) has a water discharge port (30) for discharging the washing water (W1). The water discharge port (30) opens toward the corner part (22).

[0066] In the urinal (1) of the first aspect having the above configuration, the washing water (W1) can be discharged from the water discharge port (30) of the water discharge part (3) toward the corner part (22) between the upper surface (20) and the back surface (21) of the inner surface of the bowl. The washing water (W1) discharged to the corner part (22) is not likely to immediately drop due to the surface tension generated between the washing water (W1) and the corner part (22), and is likely to spread in the extending direction of the corner part (22), that is, in the left - right direction. Therefore, in the urinal (1) of the first aspect, the washing water (W1) can be supplied to a wider range in the left - right direction from the upper end with respect to the back surface (21) of the bowl (2), so that the washing water (W1) can flow over a wider range with respect to the inner surface of the bowl.

[0067] Also, as described above in one embodiment and its modification, the urinal (1) of the second aspect additionally has the following configuration in addition to the configuration of the first aspect.

[0068] That is, in the urinal (1) of the second aspect, the water discharge part (3) is provided on the upper surface (20) such that a part of the upper surface (20) is located between the water discharge port (30) and the corner part (22).

[0069] In the urinal (1) of the second aspect having the above configuration, since the washing water (W1) is discharged from the discharge port (30) toward the upper surface (20), the washing water (W1) flowing along the upper surface (20) can be spread in the left - right direction on the upper surface (20). And the washing water (W1) spread in the left - right direction can be further spread in the left - right direction at the corner portion (22). Therefore, in the urinal (1) of the second aspect, the washing water (W1) can be made to flow over a wider range with respect to the inner surface of the bowl.

[0070] Also, like the above - described embodiment and its modification, the urinal (1) of the third aspect additionally includes the following configuration in addition to the configuration of the second aspect.

[0071] That is, in the urinal (1) of the third aspect, the upper surface (20) is inclined with respect to the horizontal plane such that the portion closer to the back surface (21) is positioned lower.

[0072] In the urinal (1) of the third aspect having the above configuration, the washing water (W1) discharged from the discharge port (30) to the upper surface (20) easily reaches the corner portion (22) along the upper surface (20), and the upper surface (20) and the corner portion (22) easily spread the washing water (W1) in the left - right direction.

[0073] Also, like the above - described embodiment and its modification, the urinal (1) of the fourth aspect additionally includes the following configuration in addition to the configuration of any one of the first to third aspects.

[0074] That is, in the urinal (1) of the fourth aspect, the water - discharging portion (3) has a water - guiding path (second water - guiding path 321) that spreads in a fan - shape in plan view. The downstream end of the water - guiding path (second water - guiding path 321) is the discharge port (30).

[0075] In the urinal (1) of the fourth aspect having the above configuration, since the washing water (W1) can be discharged in a fan - shape in plan view from the discharge port (30) of the water - discharging portion (3), it is easy to spread the washing water (W1) to both sides in the extending direction of the corner portion (22), that is, in the left - right direction.

[0076] Also, like the above-described embodiment and its modified examples, the urinal (1) of the fifth aspect additionally includes the following configuration in addition to the configuration of the fourth aspect.

[0077] That is, in the urinal (1) of the fifth aspect, the water discharge part (3) forms a part of the wall surface (35) surrounding the water guide path (second water guide path 321), and has an inner lower surface (351) located below the water guide path (second water guide path 321). A rib (36) in the form of a raised strip extending toward the water discharge port (30) is provided on the inner lower surface (351).

[0078] In the urinal (1) of the fifth aspect having the above configuration, due to the rectifying effect of the rib (36), the washing water (W1) received on the inner lower surface (351) can be spread in a direction away from the rib (36), and it is easy to spread the washing water (W1) over the entire water guide path (second water guide path 321) in a fan shape in plan view. Therefore, in the urinal (1) of the fifth aspect, it is easy to discharge the washing water (W1) in a fan shape in plan view from the water discharge port (30) of the water discharge part (3), and it is easy to spread the washing water (W1) in the extending direction of the corner part (22), that is, the left-right direction. Also, in the urinal (1) of the fifth aspect, since the water droplets remaining on the inner lower surface (351) can easily flow along the rib (36), the discharge position of the water droplets at the water discharge port (30) is likely to be stable.
