DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom unit which is an assembled bathroom.

[0002]

2. Description of the Related Art There has been known a bathroom unit in which a floor surface on a side of an entrance and exit of a bathroom is formed flat without any step to facilitate access to the bathroom. In such a bathroom unit,
As shown in FIG. 13A, a drain groove 500a is formed at the end of the floor pan 500 on the side of the washing place W along the entrance 511 of the bathroom, and a drain inflow portion is formed in the drain groove 500a. By being covered with the grating 510, the drainage on the side of the washing place W that has flowed toward the entrance 511 side of the bathroom is guided to the drain groove 500 a via the grating 510. For this reason, in this bathroom unit, the drainage of the washing place W does not flow out of the bathroom through the entrance 511 of the bathroom, even if there is no step for preventing the outflow of drainage around the entrance 511 of the bathroom. Therefore, the entrance 511 of the bathroom
The surrounding floor can be flat.

[0003]

However, in such a bathroom unit, as shown in FIGS. 13 (b) and 13 (c), if the position of the entrance 511 with respect to the bathroom is changed, the position of the drain groove 500a is changed. 3 different types of floor bread 5
00 is required. For this reason, three types of molds for the floor pan 500 are required, and the inventory quantity of the floor pan also increases, and the cost of the bathroom unit increases due to the difference in the position of the entrance 511. There was a problem of doing it.

In order to reduce the number of types of floor pans 500, for example, as shown in FIG. 14, drain grooves 500a are formed around the washing area 502 of the floor pans 500, and these are drained by gratings 510A, 510B, 510C. , 5
Some bathroom units are covered with 10D. However, in general, the bather feels uncomfortable with the grating in which the drainage inflow portion is formed, and in order to avoid entering the grating as much as possible during bathing, such a bathroom unit includes:
There was a problem that bathers felt that the washing area was narrow.

On the other hand, the grating 51 is provided at the entrance 511.
In a bathroom unit provided with a drain groove 500a covered with a zero and a step on the floor on the side of the entrance 511, a bath tub 512 is provided.
When a large amount of drainage is generated in the washing area, such as when the hot water in the inside suddenly overflows, the drainage
There is also a problem that it passes over and moves to the entrance 511.

[0007] As shown in FIG. 15, a drain groove 500 covered with a grating 510 is provided on the entrance / exit 511 side.
In the bathroom unit for the elderly, which is provided with a and has no step on the floor surface on the side of the entrance / exit 511, the height L between the floor surface of the washing room W and the upper surface of the bathtub 512 is reduced, and
It is desired to make it easy to get in and out of the washing machine 2 in this case.
It is necessary to drop it below the 02 side. For this reason,
The lower surface of the floor pan 500 on the side of the bathtub installation section 501 approaches the installation surface B of the bathroom unit.
On one side, there was a problem that the drainage pipe of this bathroom unit could not be routed sufficiently.

[0007] It is conceivable to lift the floor pan 500 as a whole and route a drain pipe below the bathtub installation part 501. In this case, however, the washing part 5 of the floor pan 500 may be used.
Because the 02 side rises, from the relationship with the dressing room side,
There is a disadvantage that the entire floor of the building becomes high.

[0008] In view of the above, the present invention provides a drainage ditch on the entrance / exit side of a bathroom and eliminates a step on the floor on the entrance / exit side to reduce the cost due to the position of the entrance / exit. It is a first object of the present invention to provide a bathroom unit which can be eliminated and which does not cause a bather to feel a washing place so narrow.

[0009] In addition to the first object, the present invention provides a bathroom unit which does not move the wastewater to the entrance / exit side even if the amount of wastewater in the washing place sharply increases. With the goal.

Further, in addition to the above first object, the present invention provides a bathroom in which a pipe can be routed without inconvenience below the floor pan on the side of the bathtub installation part even when the height of the floor pan is lowered. The purpose is to provide a unit.

[0011]

According to the first aspect of the present invention, a drainage groove is formed at an outer end of a floor of a washing room to prevent drainage from flowing out of a bathroom, and the drainage is formed. By covering the groove with a groove lid with a drainage inflow part formed,
In a bathroom unit in which a floor surface around a doorway of a bathroom can be formed flat without any level difference, a drain groove covered with a groove cover is provided on the entire outer peripheral portion of a floor portion of a washing place except a bathtub side.

According to the present invention, since the drainage groove covered with the groove cover is provided on the entire outer peripheral portion of the floor of the washing area except for the bathtub side, the entrance is provided at any outer end of the floor of the washing area. However, the floor around the entrance can be formed flat without any level difference, and the bathtub side does not have the groove cover, so that the bather does not feel the washing place narrow. in this case,
For example, if the plane shape of the washing area is rectangular, there is only one floor pan for three types of entrances.

According to a second aspect of the present invention, in the case of the first aspect, a water collecting recess covered with a drainage lid is formed at an intermediate position of a bathtub side end of a floor of a washing area. At the same time, a drain trap is attached to the floor on the bottom side of the water collecting recess to discharge the drainage from the washing area collected in the water collecting recess to the outside through the drainage inflow portion of the drain cover, and a bathtub. A drain outlet is provided at the downstream end of the closer drain, and the drain outlet is connected to the water sealing portion on the lower side of the drain trap by a drain pipe arranged below the floor.

In the present invention, the drainage water in the drainage ditch is caused to flow not into the water collecting concave portion, which is upstream of the drain trap, but into the water sealing portion, which is downstream of the drain trap.
The flow rate of drain water at the inlet side (upstream side) of the drain trap is reduced, and the flow resistance of drain water to the drain trap can be reduced accordingly. Therefore, in the bathroom unit 1, a large amount of wastewater can be flown to the wastewater trap. Further, according to the present invention, even if the water collecting recess is made shallow so that the amount of protrusion below the drain trap from the floor of the washing place is reduced, the drainage in the drain canal can be sealed without inconvenience at the lower part of the drain trap. The floor of the washing room can be lowered to the installation surface side of the bathroom unit.
For this reason, when the floor surface of the entrance / exit portion of the bathroom unit is made flat without any step, it is not necessary to raise the floor surface of the dressing room side more than necessary.

According to a third aspect of the present invention, in the case of the second aspect of the present invention, the upper surface of the outer peripheral portion of the floor of the washing area except for the bathtub side is formed at the same level, and the floor of the washing area is formed. That is, the upper surface is inclined downward from the outer peripheral portion toward the water collecting recess.

According to the present invention, most of the wastewater on the washroom side is collected in the drainage concave side, and only the wastewater flowing out to the drainage side is collected in this drainage groove. For this reason, the amount of drainage discharged to the drain can be reduced, and
Drainage can be prevented from moving to the entrance / exit side of the bathroom beyond the gutter.

According to a fourth aspect of the present invention, in the case of the second or third aspect of the present invention, the bath tub installation portion of the floor pan on which the bath tub is installed is replaced with the floor pan of the washing place. In addition to being formed one step lower than the washing part side, a notch is formed in a bank part separating the bath tub setting part and the washing part part of the floor pan, and the notch part is provided below the apron positioned on the bank part by the notch part. That is, an opening communicating with the installation section is formed.

According to the present invention, the cutout provided in the bank forms an opening below the apron to the bathtub installation section, so that the hot water overflows from the bathtub and suddenly moves to the washing place side. Even if a large amount of drainage is generated, the drainage can be drained not only from the drainage ditch and the water collecting recess but also from the opening to the bathtub installation part side. Therefore, it is possible to prevent the washing place from being filled with drainage. In this case, since the bath tub installation part side of the floor pan is one step lower than the washing place side, the height of the straddle from the washing place upper surface to the bath tub upper surface can be reduced, and the entrance and exit to and from the bath tub become easy. Further, according to the present invention, since the apron can be supported from below by putting a hand in the cutout portion of the bank portion, when the apron is removable, the apron can be easily attached and detached.

According to a fifth aspect of the present invention, in the case of the fourth aspect, the notch is formed at the downstream end side of the drain groove of the bank, and the opening formed by the notch is formed. With at least a part left on the lower side of the groove lid,
This opening is covered with a groove cover so that it cannot be seen from the washing place side.

According to a sixth aspect of the present invention, in the case of the fourth aspect, the notch is formed in a portion of the bank facing the water collecting recess, and the opening formed by the notch is formed. The opening is covered with a drain cover so that at least a part of the opening is left on the lower surface side of the groove lid so that the opening cannot be seen from the washing place side.

According to a seventh aspect of the present invention, in the case of the first aspect of the present invention, the bath tub installation portion side of the floor pan on which the bath tub is installed is used as the floor portion of the washing pan. The lower part is formed one step lower than the side, and a step is formed at the opposite ends of the bathtub installation part in contact with the washing area, with the bottom raised above the center part, and the piping space below this step Is formed.

According to the present invention, even if the bath pan installation section side of the floor pan is lower than the washing place side by one step, the height of straddling the bath tub is reduced, and the lower part of the bath tub installation section side is brought closer to the installation surface side. By utilizing the routing space formed below the step portion of the bathtub installation portion, for example, the discharge pipe from the drain trap can be routed also to the bathtub installation portion side. In this case, the steps of the bathtub setting section are formed at opposite ends of the bathtub setting section that is in contact with the washing area, so that the steps are located below the deck of the bathtub, and this step does not hinder the setting of the bathtub. Absent.

As shown in the figure, the floor pan 2 is connected to the outside of the bathroom installation space through the routing space V below the step portion 211 formed on one side of the bathtub installation portion 21. In addition, discharge pipe 1
5 may be connected to the outside of the bathroom installation space through the routing space V below the step portion 211 on the other side of the floor pan 2, or may be directly connected to the outside of the bathroom installation space from the washing section 20 side of the floor pan 2. You may make it connect to piping.

Next, the flow of drainage in the bathroom unit 1 will be described. Most of the drainage on the washing place W side is collected directly on the trap cover 9 side along the inclination of the upper surface of the land portion 202 of the floor pan 2 or on the trap cover 9 side via the drain recess 203. After being collected, the water passes through the drainage inflow portion H of the trap cover 9 and the like,
Collected in the collecting recess 201. Then, the wastewater is collected in the water sealing section 120a from the water sealing pipe 122 after the foreign matter such as the hair is removed by the eye plate 123 of the water trap 12, and the overflow water from the water sealing section 120a It is discharged to the outside through the discharge pipe 15 connected to the entrance / exit 120b. Therefore, the odor on the discharge pipe 15 side is blocked by the water sealing portion 120 a of the drain trap 12, and is not transmitted to the water collecting recess 201 side of the floor pan 2. In addition,
Since the drainage on the trap cover 9 is blocked by the projection 91, it does not flow toward the bath tub installation section 21 of the floor pan 2.

Further, the drainage from the washing place W which has flowed out from the land portion 202 of the floor pan 2 to the groove cover 7 and the grating 8 is discharged into the drainage inflow portions F and G of the groove cover 7 and the grating 8.
Flows into the drain 200 through the drain 200
Through the drainage channel portion 200a of the tub 3
00c is discharged into the second drain pipe 14. Then, the drainage in the second drain pipe 14 is directly collected in the water sealing portion 120a of the drain trap 12, and then the drain trap 12
Is discharged to the outside through the discharge pipe 15.

Accordingly, the drainage water on the washing place W side is not discharged out of the bathroom beyond the groove cover 7 and the grating 8.
On the grating 8 side where is formed, even if the water return step is not provided around the door frame 5 and the floor around the entrance is flattened, the drainage is discharged outside beyond the door frame 5. Never. In this case, the second drain pipe 14 is directly connected to the water sealing section 120a of the drain trap 12, and the second drain pipe 14 is also filled with drain water to the same level as the upper end of the water sealing section 120a. Therefore, the odor in the second drain pipe 14 is not transmitted to the drain groove 200 side.

On the other hand, on the bathtub setting part 21 of the floor pan 2,
Although a large amount of drainage does not occur, drainage also occurs on the side of the bathtub installation section 21 due to a gap formed between the bathtub 3 and the wall panel 4 and a gap between the apron 6 and the bank 22 of the floor pan 2. Leakage occurs and drainage also occurs on the bathtub installation part 21. This drainage is collected on the check valve 11 side along the inclination of the upper surface of the bathtub installation part 21, and after the foreign matter such as hair is removed by the countersunk part 11 a of the check valve 11, the first drain pipe 13 is removed. Drain trap 1
The water is collected directly in the second water sealing section 120a. In this case, the first
In the drain pipe 13, the water sealing part 1 of the drain trap 12 is always provided.
Since the drainage is filled to the level at the upper end of 20a,
The odor in the first drain pipe 13 is caused by the bathtub installation part 2 of the floor pan 2.
It is not transmitted to one side.

The drainage in the water reservoir 30 of the bathtub 3 is
The water is discharged into the first drain pipe 13 through the bathtub drain pipe 16. In this case, since a large amount of wastewater is discharged to the drain trap 12 side at a time, the inside of the first drain pipe 13 overflows with wastewater,
This overflowing water tends to flow backward to the bath tub installation section 21 side of the floor pan 2. In this case, since the floating plate 11 b of the check valve 11 closes the opening K of the perforated plate section 11 a, the overflow water flows from the first drain pipe 13. No backflow of drainage occurs.

Next, a case will be described in which a bather enters the water reservoir 30 of the bathtub 3 which is almost full and is filled with hot water, and instantaneously a large amount of drainage is generated on the washing place W side.
In this case, the amount of drainage is reduced by the second drain pipe 14 or the drain trap 12.
, The inside of the drain 200 and the water collecting recess 201 is temporarily filled with water, and the washing place W
The side may be filled with drainage and the drainage may move to the door frame 5 side.

However, in the bathroom unit 1, the first and second notches 220, 221 are provided in the bank 22 of the floor pan 2.
Since the openings D1 and E1 and the flow path J are formed below the groove cover 7 and the trap cover 9, the openings D1 and E1 and the flow path J are formed below the groove cover 7 and the trap cover 9.
A part of the wastewater in 1 flows through the openings D1 and E1 and the flow path J to the bathtub installation part 21 side, and reduces the wastewater on the washing place W side. For this reason, the washing place W is not filled with the drainage, and the drainage of the washing place W is prevented from moving to the door frame 5 side. In this case, the drainage on the bathtub installation part 21 side is the check valve 1
1. When discharged through the first drain pipe 13 to the drain trap 12 side, the first drain pipe 13 becomes full of drain water, and the floating plate 11b of the check valve 11 covers the perforated portion 11a. In
It is temporarily stored on the bathtub installation part 21.

As described above, in this bathroom unit 1,
Since the drain groove 200 covered with a groove cover such as the groove cover 7 and the grating 8 is provided on the entire outer peripheral portion of the washing section 20 of the floor pan 2 except for the bathtub 3 side, the drain groove 2 of the floor pan 2 is provided.
The doorway (door frame 5) can be provided on any outer end side along 00A, 200B, and 200C without providing a water return step on the floor surface.

That is, in the bathroom unit 1, the washing area 2 of the floor pan 2, which can be provided with an entrance to the bathroom, is provided.
Since the entrance can be provided at any end of the floor without causing a step on the floor surface, the types of the floor pan 2 due to the difference in the position of the entrance can be reduced, and the floor pan 2 can be manufactured. Can be reduced, and the stock amount of the floor pan 2 can also be reduced. In this case, since the groove covers such as the groove cover 7 and the grating 8 are not provided on the entire circumference of the washing place W, the bather does not feel that the washing place W is narrow due to the groove cover.

Further, in the bathroom unit 1, the grating 8 in which a large number of drainage inflow portions G are formed is used only for the drainage groove 200B on the entrance / exit side, while the other drainage grooves 200B are not used.
A, 200C uses the groove cover 7 in which the drainage inflow portion is formed only at both end sides, so that compared to the conventional bathroom unit using grating for all the groove covers,
As a whole, it is possible to easily clean the groove lid. The land portion 202 of the floor pan 2 is provided on the upper surface of the groove cover 7.
Since the same pattern as that described above is formed, the bather is less likely to feel a sense of discomfort in the groove cover 7, and can accordingly feel the washing place W wider.

Further, in this bathroom unit 1, in addition to the drainage on the washing place W side being collected from the water collecting recess 201 into the water sealing pipe 122 which is the upstream part of the drain trap 12, the second drainage pipe 14 is also drained from the drainage groove 200. Since all the wastewater is collected in the water sealing section 120a on the downstream side of the drain trap 12, the wastewater is collected in the water sealing pipe 122 of the drain trap 12. 1
The flow resistance of the wastewater on the side 22) can be reduced, and a correspondingly large amount of wastewater can flow through the wastewater trap 12. Therefore, even if a large amount of wastewater is suddenly generated in the washing place W, the wastewater can be quickly discharged to the outside through the wastewater trap 12 without being accumulated in the washing place W.

In this case, the drainage in the drainage groove 200 does not need to flow toward the water collecting recess 201, so that the bottom of the water collecting recess 201 does not need to be lower than the bottom surface of the drainage groove 200. 201 can be made shallower. Therefore, the amount of protrusion of the drain trap 12 projecting downward from the lower surface of the washing section 20 of the floor pan 2 can be reduced, and the washing section 20 of the floor pan 2 can be made closer to the installation surface B accordingly. Therefore, the floor surface around the entrance (door frame 5) of the bathroom can be flattened without making the floor surface N1 (see FIG. 4) on the undressing room N side higher than usual.

In the bathroom unit 1, the upper surface S 1 of the outer peripheral portion of the land portion 202 of the washing section 20 is set to the same level, and the upper surface S of the land portion 202 is inclined downward from the outer peripheral portion to the water collecting recess 201. Because of this, much of the wastewater from the washing place W can be poured into the water collecting recess 201 side, and the amount of wastewater flowing to the groove cover 7 and the grating 8 side can be reduced. Therefore, it is possible to sufficiently prevent the drainage from flowing to the door frame 5 side beyond the grating 8. Of course, since the upper surface S1 of the outer peripheral portion of the land portion 202 is at the same level, even if the entrance (door frame 5) is provided at any end of the washing section 20 of the floor pan 2, the upper surface of the groove lid is not affected. There is no step between the upper surface of the land portion 202 and the upper surface.

Further, in this bathroom unit 1, a bank portion 2 that separates a washing area 20 of the floor pan 2 from a bathtub installation section 21.
2, first and second cutouts 220 and 221 are provided, and a passage J and openings D1 and E1 for communicating between the washing section 20 and the bathtub installation section 21 are formed below the apron 6 placed on the bank section 22. Therefore, even if the drainage of the washing place W increases rapidly, a part of the drainage can be discharged to the bathtub installation part 21 side. That is, even when a large amount of drainage is generated in the washing basin W in a short time, such as when the hot water in the basin 30 of the bath tub 3 suddenly overflows, the washing basin W is not filled with the drainage. Therefore, the drainage does not move to the door frame 5 side beyond the grating 8.

In this bathroom unit 1, the openings D1 and E1 below the apron 6 are covered by the trap cover 9 and the groove cover 7 and cannot be seen from the washing place W side.
These do not impair the appearance in the bathroom.

Further, in this bathroom unit 1, the bathtub 3
The bottom 210 of the bathtub installation part 21 of the floor pan 2 is fixed to the land 20
The lower part of the bath pan installation part 21 of the floor pan 2 does not hinder the installation of the bath tub 3 although the distance between the lower surface side of the bath tub installation part 21 and the installation surface B of the bathroom unit 1 is small. Steps 211 are provided on both sides of the
Since a piping space V is formed below 1,
The discharge pipe 15 from the drain trap 12 can be easily routed outside the bathroom installation space through the bathtub installation section 21 side.

Further, in this bathroom unit 1, the hand can be inserted below the apron 6 through the openings D and E by removing the groove cover 7, the trap cover 9 and the bank cover 10, so that the apron 6 Can be easily attached and detached. Therefore, cleaning around the lower part of the bathtub 3 can be facilitated.

In this bathroom unit 1, the drain 2
Since the water return 231 of the wall mounting portion 23 facing 00 is cut in advance, an entrance having no steps around the floor surface can be easily provided in this portion. In this case, since the water return 231 is left in a part of the wall mounting part 23, the installation of the wall panel 4 in this part is also facilitated.

In this bathroom unit 1, floor pan 2
The first and second cutouts 220 and 221 are provided in the bank portion 22 of this embodiment. However, the same effect can be obtained by providing the cutout portion only in the drain groove 200 side of the bank portion 22 or only in the water collecting recess 201 side. Can be obtained.
