Description

[Technical Field]

[0001] The present invention relates to a bathroom unit. [Background technology]

[0002] For example, the bathtub described in Patent Document 1 below is known as a bathtub installed in a house or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-192205 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors of the present application have found that there is room for improvement in the efficiency of draining water when draining water down from a bathtub installed in a bathroom.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a bathroom unit that can drain water efficiently. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. The bathroom unit of the present invention comprises a washing area floor, a bathtub floor that is stepped down from the washing area floor, a bathtub placed on the bathtub floor, a drain trap that is placed on the bathtub floor and has an inlet for drainage from the bathtub, and an upper lid that is placed above the opening surface of the inlet, and a siphon generating member is provided in the space between the opening surface and the upper lid.

[0007] According to this invention, a siphoning member is provided in the space between the opening surface and the top lid. This allows a siphoning effect to occur inside the drain trap when drainage water flows down from the inlet toward the drain trap. This allows for efficient drainage from the bathtub. Because the siphoning member is located in the space between the opening surface and the top lid, if the siphoning member is removable from the top lid or the drain trap, it can be easily removed.

[0008] The siphoning member may also include a lower cover part disposed above the opening surface in a direction parallel to or intersecting the opening surface.

[0009] In conventional bathroom units, air bubbles can sometimes form when draining water from the bathtub. When this happens, the air bubbles are sucked into the drain trap's inlet before they collapse. This means it takes time for the drain trap to fill with wastewater. This means that the siphon effect does not occur, resulting in poor drainage efficiency. According to this invention, the siphoning member includes a lower cover part arranged above the opening surface, parallel to or intersecting the opening surface. This prevents air bubbles in the drain from flowing down from the inlet to the drain trap. This makes it easier for the drain trap to fill with drainage. This makes it easier for the siphoning phenomenon to occur in the drain trap. This allows for efficient drainage from the bathtub.

[0010] The siphon generating member may also include a plate-like part disposed below the top lid in a direction intersecting the top lid.

[0011] In conventional bathroom units, if the flow of wastewater is strong, it can swirl above the drain trap. In this case, the flow of wastewater becomes turbulent above the drain trap. This makes it difficult for the wastewater to flow into the drain pipe. As a result, it takes time for the inside of the drain trap to fill with wastewater. Therefore, it is difficult for the siphoning phenomenon to occur in a short time, which leads to the problem of poor drainage efficiency. According to this invention, the siphoning member includes a plate-shaped part arranged below the top lid in a direction intersecting the top lid. This prevents vortexes from being generated by the wastewater flowing down near the opening surface of the inlet. This prevents air from entering the inside of the drain trap. This makes it easier for the inside of the drain trap to be filled with wastewater. This makes it easier for the siphoning phenomenon to occur in the drain trap. This allows for efficient drainage from the bathtub.

[0012] The siphon generating member may further include a lower cover part connected to the lower end of the plate-like part and arranged parallel to or intersecting the opening surface.

[0013] According to this invention, the siphon generating member further includes a lower cover member connected to the lower end of the plate-shaped member and arranged parallel to or intersecting the opening surface. This allows the plate-shaped member to prevent vortex generation and the lower cover member to prevent air bubbles from merging, all in one siphon generating member. This makes it easier to generate the siphon phenomenon in the drain trap. This allows for more efficient drainage of water from the bathtub.

[0014] A slit may be provided on the lower surface of the upper cover, and the upper end of the plate-like component may be removably disposed in the slit.

[0015] According to this invention, a slit is provided on the underside of the top lid, and the upper end of the plate-shaped component is removably disposed in the slit. This allows the siphon generating member to be fixed to the top lid. Therefore, the siphon generating member can be fixed without a separate fixing structure. Furthermore, because the top lid and the siphon generating member are removable, the top lid and the siphon generating member can be easily cleaned.

[0016] The device may further include a hair catcher arranged above the opening surface, and the lower end of the siphon generating member may be removably arranged on an attachment portion formed on a part of the hair catcher.

[0017] According to this invention, the lower end of the siphon generating member is removably disposed on a mounting portion formed on a part of the hair catcher. This allows the siphon generating member to be fixed to the hair catcher. Therefore, the siphon generating member can be fixed without having a separate fixing structure. Furthermore, because the hair catcher and the siphon generating member are detachable, the hair catcher and the siphon generating member can be easily cleaned. [Effects of the Invention]

[0018] According to the present invention, a bathroom unit that can drain water efficiently can be provided. [Brief explanation of the drawings]

[0020] Hereinafter, a bathroom unit 100 according to one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the bathroom unit 100 comprises a washing area floor 10, a bathtub floor 20, a bathtub 30, a drain trap 40, an upper cover 50, a hair catcher 60, and a siphon generating member 70. The washing area floor 10 is the part where the user of the bathroom unit 100 stands. It is preferable that the washing area floor 10 is inclined with the drain trap 40 as the lowest point so that water does not accumulate on the washing area floor 10.

[0021] The bathtub floor 20 is provided in a stepped manner from the washing area floor 10. The bathtub 30 is placed on the bathtub floor 20. The bathtub floor 20 is provided with a slope to make it easier for the wastewater flowing down from the bathtub 30 to be transported to the drain trap 40. Bathtub 30 is placed on bathtub floor 20. Bathtub 30 has bathtub drain groove 31. Bathtub drain groove 31 is used to drain water stored inside bathtub 30. It is preferable that the bottom of bathtub 30 is sloped with bathtub drain groove 31 as its lowest point.

[0022] Drain trap 40 transports wastewater flowing down from bathtub 30 to a sewer or the like. Drain trap 40 is placed on bathtub floor 20. As shown in FIG. 2, drain trap 40 has an inlet 41 and a connection port 42. The inlet 41 is located at the lowest point of the slope of the bathtub floor 20. The opening surface 41a of the inlet 41 is arranged facing upward. The upper edge of the inlet 41 is located on an imaginary plane (not shown). The opening surface 41a refers to the space on the imaginary plane that is surrounded by the upper edge of the inlet 41. The wastewater flowing down from the bathtub drain groove 31 flows into the drain trap 40 through the inlet 41. The inlet 41 is located, for example, at the boundary between the washing area floor 10 and the bathtub floor 20, as shown in Figure 2. The inlet 41 is not located below the bathtub 30. The inlet 41 is located at the bottom of a recess 10d provided in the washing area floor 10, as shown in Figures 2 and 3.

[0023] The connection port 42 is connected to a drain pipe P as shown in FIG. 2. The wastewater that flows down from the inlet 41 into the inside of the drain trap 40 is transported to the drain pipe P via the connection port 42. The drain pipe P transports the wastewater to a sewer system (not shown). In this way, the wastewater that flows down into the drain trap 40 is transported to the sewer system.

[0024] The top cover 50 is positioned above the opening surface 41a of the inlet 41. As shown in FIG. 4, the top cover 50 is placed on a step 10s provided in the washing area floor 10. As shown in FIG. 2, the top cover 50 is positioned so as to cover the inlet 41, which is located at the bottom of a recess 10d provided in the washing area floor 10. This serves to prevent the feet, etc. of a user of the bathroom unit 100 from accidentally entering the inlet 41, or to prevent objects from being accidentally dropped into the inlet 41. In addition, the hair catcher 60 can be cleaned by attaching and detaching the top cover 50. In this embodiment, a slit 51 is provided on the underside of the top cover 50. The upper end of a plate-shaped part 72a, described later, is removably positioned in the slit 51.

[0025] The hair catcher 60 is disposed above the opening surface 41a. As shown in Figures 2 and 3, the hair catcher 60 is, for example, a sieve-shaped member. When hair or the like gets into the inlet 41, the hair catcher 60 prevents the hair from entering the inside of the drain trap 40. The hair catcher 60 has an attachment part 61. The lower end of the siphon generating member 70 is removably disposed on the attachment part 61.

[0026] The siphon generating member 70 is provided in the space between the opening surface 41a of the inlet 41 and the top cover 50. The siphon generating member 70 regulates the flow of water entering the drain trap 40 from the inlet 41. The siphon generating member 70 makes it easier for the inside of the drain trap 40 to be filled with wastewater. In this way, the siphon generating member 70 generates a siphoning phenomenon inside the drain trap 40.

[0027] In this embodiment, siphon generating member 70 has a first siphon generating member 71, a second siphon generating member 72, and a third siphon generating member 73. Hereinafter, when there is no need to distinguish between first siphon generating member 71, second siphon generating member 72, and third siphon generating member 73, they will be referred to as siphon generating member 70.

[0028] As shown in Fig. 5, the first siphon generating member 71 includes a lower lid part 71a. As shown in Fig. 6, the lower lid part 71a is a plate-shaped member. As shown in Fig. 5, the lower lid part 71a is disposed above the opening surface 41a of the inlet 41, in a direction parallel to or intersecting the opening surface 41a.

[0029] The lower cover part 71a is fixed, for example, to the bottom of the recess 10d in the washing area floor 10. The lower cover part 71a is fixed, for example, by adhesive bonding to the recess 10d. The lower cover part 71a may also be fixed to the recess 10d with a bolt and nut. The lower cover part 71a may also be fixed by being inserted into an insertion part formed in the washing area floor 10. The insertion part is, for example, a gap into which the end of the lower cover part 71a can be inserted.

[0030] The lower lid part 71a may be attached to an attachment part 61 formed on the hair catcher 60. The attachment part 61 may have, for example, a slit-like shape. In this case, the lower lid part 71a has a shape that fits into the slit-like shape of the attachment part 61. The lower lid part 71a may be fixed by being inserted into the attachment part 61.

[0031] When the lower cover part 71a is placed on the opening surface 41a, air bubbles contained in the wastewater are crushed while remaining in the lower cover part 71a when the wastewater flows down from the inlet 41 into the drain trap 40. In this way, the lower cover part 71a has the role of preventing air bubbles contained in the wastewater from entering the drain trap 40 when the wastewater flows down into the drain trap 40. The gap between the lower cover part 71a and the side wall of the recess 10d in the washing area floor 10 in which the drain trap 40 is provided is preferably, for example, 10 mm. The vertical distance between the lower cover part 71a and the opening surface 41a of the drain trap 40 is preferably, for example, 14 mm.

[0032] 7, 8 and 9, the second siphon generating member 72 includes a plate-shaped part 72a. The plate-shaped part 72a is disposed below the top cover 50 in a direction intersecting with the top cover 50. The plate-shaped part 72a is attached to, for example, a slit 51 formed on the lower surface of the top cover 50. At this time, the upper end of the plate-shaped part 72a has a shape that fits into the slit 51. The upper end of the plate-shaped part 72a is inserted into the slit 51 and fixed.

[0033] Plate-shaped part 72a may be attached to attachment part 61 formed on hair catcher 60. Attachment part 61 has, for example, a slit-like shape. In this case, plate-shaped part 72a has a shape that fits into attachment part 61 at the lower end of plate-shaped part 72a. Plate-shaped part 72a may be fixed so that the lower end of plate-shaped part 72a is inserted into attachment part 61. The plate-shaped part 72a may be fixed at only the upper end, at only the lower end, or at both the upper and lower ends.

[0034] When the plate-shaped part 72a is placed under the upper cover 50, i.e., on the opening surface 41a, when wastewater flows from the inlet 41 into the drain trap 40, the flow of the wastewater prevents a vortex from being formed near the inlet 41. In this way, the plate-shaped part 72a plays a role in preventing a vortex from being formed by the wastewater when the wastewater flows down into the drain trap 40.

[0035] As shown in FIGS. 10, 11, 12 and 13, the third siphon generating member 73 includes a plate-shaped part 72a and a lower cover part 71a. Plate-shaped part 72a has the same configuration as second siphon generating member 72. That is, plate-shaped part 72a is disposed below top cover 50 in a direction intersecting with top cover 50. The lower lid part 71a has the same configuration as the first siphon generating member 71. That is, the lower lid part 71a is disposed parallel to or intersecting with the opening surface 41a. In the second siphon generating member 72, the lower lid part 71a is connected to the lower end of the plate-shaped part 72a.

[0036] As shown in FIG. 13, the third siphon generating member 73 is formed into an inverted T shape by a plate-like part 72a and a lower cover part 71a. Similar to the second siphon generating member 72, the third siphon generating member 73 is fixed by attaching the upper end of the plate-like part 72a to the slit 51 formed in the lower surface of the upper cover 50, for example.

[0037] Similar to the first siphon generating member 71, the third siphon generating member 73 may have its lower cover part 71a fixed to the bottom of the recess 10d in the washing area floor 10 with tape. The lower cover part 71a may be inserted into an insertion part formed in the washing area floor 10 and fixed therein. The lower cover part 71a may be attached to an attachment part 61 formed on the hair catcher 60. Only the plate-shaped part 72a may be fixed to the third siphon generating member 73. Only the bottom cover part 71a may be fixed to the third siphon generating member 73. Both the plate-shaped part 72a and the bottom cover part 71a may be fixed to the third siphon generating member 73.

[0038] Next, the discharge of water W (wastewater) by bathroom unit 100 according to this embodiment will be described with reference to Figures 14, 15, and 16. As shown in Figure 14, water W stored in bathtub 30 is drained onto bathtub floor 20 via bathtub drain groove 31. The water W that has moved to bathtub floor 20 is carried to inlet 41 of drain trap 40 by the slope provided in bathtub floor 20. The water W that has been carried to inlet 41 enters the inside of drain trap 40. At this time, if the speed at which water W is discharged from bathtub drain groove 31 is faster than the speed at which water W flows down into drain trap 40, water W will accumulate on bathtub floor 20, as shown in Figure 15.

[0039] As shown in Figure 15, when water W accumulates on the bathtub floor 20, the inside of the drain trap 40 and the drain pipe P connected to the drain trap 40 are not filled with water W. At this time, the siphon generating member 70 provided between the inlet 41 of the drain trap 40 and the top cover 50 acts to fill the inside of the drain trap 40 with water W.

[0040] This causes a siphoning phenomenon inside the drain trap 40. When the siphoning phenomenon occurs, the speed at which the water W flows inside the drain trap 40 increases. This allows the water W stored on the bathtub floor 20 to be transported to the drain trap 40 efficiently. The siphoning generated inside the drain trap 40 by the siphon generating member 70 continues until the amount of water W accumulated on the bathtub floor 20 becomes sufficiently small, as shown in Figure 16. This prevents the water W from overflowing onto the washing area floor 10.

[0041] As described above, according to the bathroom unit 100 of this embodiment, a siphon generating member 70 is provided in the space between the opening surface 41a and the top cover 50. This allows a siphoning phenomenon to occur inside the drain trap 40 when drainage water flows down from the inlet 41 toward the drain trap 40. This allows for efficient drainage from the bathtub 30. Because the siphon generating member 70 is disposed in the space between the opening surface 41a and the top cover 50, if the siphon generating member 70 is made removable from the top cover 50, the drain trap 40, etc., it can be easily removed.

[0042] In conventional bathroom units (100), air bubbles can sometimes form when draining water from the bathtub (30). When this happens, the air bubbles are sucked into the inlet (41) of the drain trap (40) before they collapse. This means it takes time for the inside of the drain trap (40) to fill with wastewater. This prevents the siphon effect from occurring, resulting in poor drainage efficiency. In contrast, siphoning member 70 includes lower cover part 71a arranged above opening surface 41a in a direction parallel to or intersecting opening surface 41a. This prevents air bubbles in the wastewater from flowing down from inlet 41 to drain trap 40. This makes it easier for the inside of drain trap 40 to be filled with wastewater. This makes it easier for the siphoning phenomenon to occur in drain trap 40. This allows for efficient drainage from bathtub 30.

[0043] In conventional bathroom units 100, if the flow of wastewater is strong, it can swirl above the drain trap 40. In this case, the flow of wastewater becomes turbulent above the drain trap 40. This makes it difficult for the wastewater to flow into the drain pipe P. As a result, it takes time for the inside of the drain trap 40 to fill with wastewater. This makes it difficult for the siphoning phenomenon to occur in a short period of time, resulting in poor drainage efficiency. In contrast, siphoning member 70 includes plate-shaped component 72a disposed below top lid 50 in a direction intersecting top lid 50. This prevents vortexes from being generated by the flowing wastewater near opening surface 41a of inlet 41. This prevents air from entering inside drain trap 40. This makes it easier for the inside of drain trap 40 to be filled with wastewater. This makes it easier for the siphoning phenomenon to occur in drain trap 40. This allows for efficient drainage from bathtub 30.

[0044] Siphon generating member 70 also includes lower cover member 71a, which is connected to the lower end of plate-shaped member 72a and is arranged parallel to or intersecting opening surface 41a. This allows the single siphon generating member 70 to achieve both the effect of preventing vortex generation by the plate-shaped member and the effect of preventing air bubbles from merging by lower cover member 71a. This makes it easier to generate the siphon phenomenon in drain trap 40. This allows water to be drained from bathtub 30 more efficiently.

[0045] Furthermore, a slit 51 is provided on the underside of the top cover 50, and the upper end of the plate-shaped part 72a is removably disposed in the slit 51. This allows the siphon generating member 70 to be fixed to the top cover 50. Therefore, the siphon generating member 70 can be fixed without having a separate fixing structure. Furthermore, because the top cover 50 and the siphon generating member 70 are removable, the top cover 50 and the siphon generating member 70 can be easily cleaned.

[0046] Furthermore, the lower end of siphon generating member 70 is removably disposed on mounting portion 61 formed on a part of hair catcher 60. This allows siphon generating member 70 to be fixed to hair catcher 60. Therefore, siphon generating member 70 can be fixed without having a separate fixing structure. Furthermore, because the hair catcher 60 and siphon generating member 70 are detachable, the hair catcher 60 and siphon generating member 70 can be easily cleaned.

[0047] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the siphon generating member 70 may be molded integrally with the top cover 50. The siphon generating member 70 may be molded integrally with the hair catcher 60. The siphon generating member 70 may be molded integrally inside the recess 10d of the washing area floor 10. Furthermore, the siphon generating member 70 may not be disposed so as to be detachable from the hair catcher 60, but may simply be in contact with it.

[0048] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
