Abstract

PROBLEM TO BE SOLVED: To provide a bathtub with a wash place, in which the usage of a grating as an overflowing-water countermeasure from the bathtub can be inhib ited minimally even when a stepped section is not formed or only a small stepped section is formed between the floor faces of the wash place and an entrance section. SOLUTION: A groove section 102, in which overflowing water is flowed, is formed from the internal surface side of the bathtub 10 to the external surface side facing the wash place 11 in a part of the upper edge section 101A of the bathtub 10 on the wash place 11 side while the groove section 102 side of an apron 12 formed so as to be continued to the external surface side of the upper edge section 101A is indented to the bathtub 10 side up to the place of the wash place 11 extending over the vertical direction, and a drainage ditch Q communicated with the draining section 111 of the wash place 11 is formed to the lower section of a section R surrounded by the indented section 12a of the apron 12. Overflowing water passed through the groove section 102 is introduced to the draining section 111 of the wash place 11 from the drainage ditch Q through the indented section 12a of the apron 12, and a large quantity of overflowing water is not flowed to the entrance section 3a side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bathtub fitted in a support frame formed integrally with a washing place, or
The present invention relates to a bathtub with a washing place in which a bathtub and a washing place are integrally formed. More specifically, there is no step between the floor of the washing place and the floor of the entrance, or a small step is provided. Not about bathtubs with washrooms.

[0002]

2. Description of the Related Art In a bathroom unit, a step between a floor of a bathroom and a doorway is reduced or eliminated so that even an elderly person with weak legs can easily enter and exit the bathroom. We need to be able to do that.

[0003] On the other hand, if the step between the floor of the bathroom and the entrance is small, the overflow water generated by the bather entering the bathtub full of water reaches the entrance of the bathroom and flows out to the dressing room side. There is a risk of doing this. For this reason, as shown in FIG. 4, in the bathtub 500 with a washing basin in which the bathtub 510 and the washing basin 520 are integrally formed, large drain grooves 521 and 522 are formed on the four sides or three sides of the outer periphery of the washing basin 520. Even if a large amount of overflow water W is generated from the bathtub 510 to the washing area 520 in a short time, the overflow water W
Gratings 530,5 with numerous drainage inlets
The overflow water W is poured into the drain grooves 521 and 522 through the base 31 so that the overflow water W does not reach the entrance 540 side.

[0004]

However, the grating 53 is provided on four or three sides of the outer periphery of the washing area 520.
By providing the large drain grooves 521 and 522 covered by 0,531, there is a problem that a bather feels that the washing place 520 is narrow. Grating 530,
The 531 has a problem that it is not easy to clean because a large number of grooves are formed in the 531 and the shape is complicated and the weight is large.

[0005] These problems caused by the grating and the like also occur in a bathtub with a washing place of a type in which the bathtub is fitted into a support frame formed integrally with the washing place.

[0006] In view of the above, the present invention provides a method of grating as a countermeasure against overflow of water from a bathtub even if there is no step between the floors of the washing area and the entrance / exit, or even if no small steps are provided. It is an object of the present invention to provide a bathtub with a washing place that can minimize the amount of use.

[0007]

According to the first aspect of the present invention, a bathtub is fitted into a support frame formed integrally with a washing place, or the bathtub and the washing place are formed integrally. In a bathtub with a washing room where no step is provided between the floor of the washing room and the floor of the entrance provided on the washing room side, or where no small steps are provided, the bathtub on the washing room side On the part of the upper edge of the apron, a groove for overflowing water is formed from the inner surface of the bathtub to the outer surface facing the washing area, and the apron is provided so as to continue to the outer surface of the upper edge. Is depressed toward the bathtub side in the vertical direction up to the position of the washing place, and a drainage channel communicating with the drainage part of the washing place is provided below the portion surrounded by the recessed portion of the apron.

According to the present invention, for example, when a bather enters a bath tub in which the hot water is almost completely filled, the surface of the hot water rises by a predetermined amount from the bottom surface of the groove formed in the upper edge of the bath tub. The amount of rise of the molten metal surface above the upper edge of the bathtub decreases by the depth of the groove. For this reason, the total amount of overflow water that overflows the entire upper edge of the bathtub and overflows to the washing area decreases, and most of this overflow water does not reach the entrance and exit side, but flows from the drainage channel on the apron side to the washing area. Effluent is drained or drained directly into the drainage area of the washing area. On the other hand, when the hot water level falls from the upper surface of the upper edge of the bathtub, the hot water in the bathtub is discharged to the washing place side only through the groove of the upper edge portion. In this case, the overflow water flows only through the width of the groove, so that the flow rate is limited, and at the same time, the portion surrounded by the recess is guided by the apron recess formed below the groove. Flows toward the drainage channel formed below For this reason, much of this overflow water does not reach the entrance / exit side, but flows from the drainage channel on the apron side to the drainage part of the washing place.

Therefore, the amount of overflowing water flowing into the entrance of the bathroom is small. Therefore, when there is no step between the washing area and the floor of the entrance, for example, at the entrance of the washing area, It is sufficient to provide a small drain groove and cover this groove with a groove cover having a drain inflow portion, and it is not necessary to form a large groove portion covered with grating formed with a large number of drain inflow portions. Absent. In addition, when there is a small step between the floor of the washing area and the entrance / exit section, the drainage groove is unnecessary on the entrance / exit side of the washing area. In this case, the small step refers to, for example, a step having a maximum of about 20 mm.

According to a second aspect of the present invention, in the case of the first aspect of the present invention, a large chamfered portion is formed at a corner on the washing side of the groove so that overflow water from the bathtub flows along the apron. Or that the corner is a curved portion having a large radius of curvature.

According to the present invention, the overflow water flowing toward the washing place through the groove at the upper edge of the bathtub flows substantially along the apron through a chamfer or a curved portion formed at a corner of the groove. Most of this overflow water flows into the drain through the apron depression. Note that a large chamfered portion is, for example, a case where one side of the chamfer is 10 mm or more, and a large radius of curvature means that, for example, a radius of curvature is 10 mm.
mm or more.

According to a third aspect of the present invention, in the case of the first aspect, the groove is formed at an intermediate portion of the upper edge of the bathtub on the side of the washing place and at least the upper edge of the bathtub. One end is to form a seat for facilitating access to the bathtub.

According to the present invention, when a bather sitting on the stool formed at the upper edge of the bathtub enters the bathtub, his feet are passed through the groove formed at the upper edge of the bathtub. It is only necessary to move the inside of the bathtub, and it is possible to reduce the amount of lifting of the foot when exceeding the upper edge of the bathtub. In addition, according to the present invention, the bather sitting on the stool on the washstand side can place his or her feet on the depression side of the apron and face the bathtub as much as possible, so that the bather can easily enter and exit the bathtub. .

According to a fourth aspect of the present invention, in the case of the first aspect, the upper edge portion of the upper edge portion of the bathtub farther from the washing place is provided at a position symmetrical to the groove portion. That is, a groove having the same shape as that of FIG.

In the present invention, since the groove is formed symmetrically at the upper edge of the bathtub, the bathtub can be covered with the bath lid without any gap.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a bathtub with a washing place according to an embodiment of the present invention.

The bathroom is formed from a bathroom unit which is an assembling bathroom, and the periphery of the floor is composed of a bathtub 1 with a washing tub 1 integrally formed with the bathtub by resin molding using FRP or the like. Have been. As shown in FIG. 1, this bathtub 1 with a washing area has a washing area 11 formed by an apron 12 beside the bathtub 10, and a small wall portion 13 at the outer peripheral end of the bathtub 10 excluding the washing area 11 side. , A wall mounting portion 14 for installing the wall panel 2 is formed, and a wall mounting portion 15 for installing the door frame 3 and the wall panel 2 for forming an entrance / exit portion is provided at an outer peripheral end of the washing place 11 except for the bathtub 10 side. , And are formed so as to follow the wall mounting portion 14.

As shown in FIG. 1, the bathtub 10 is provided with a rim 101 serving as an upper edge of the bathtub 10 at the upper end of a concave water reservoir 100, and the rim 101 is a small wall. It is formed so as to spread outward to the position of the portion 13 and the apron 12. Then, the rim 101 on the side of the washing area 11
A has a shallow groove 102 in the middle part in the left-right direction (longitudinal direction).
Are formed. The groove portion 102 is formed over the entire width of the rim portion 101A from the inner surface side of the basin portion 100 to the outer surface side facing the washing place 11 side, that is, the outer surface side of the apron 12, and overflows from the basin portion 100. Water W
Flows downward through the groove 102. In this case, a curved portion 102a having a large radius of curvature (for example, a radius of 10 mm or more) is formed at the corner of the washing portion 11 side of the groove portion 102, and overflow water W passing through the groove portion 102 flows along the apron 12. It is designed to flow downward.

The rim portion 101A is formed so that the outer surface on the intermediate portion side where the groove portion 102 is located is depressed toward the sump portion 100 side.
Are formed. The rim portion 101B on the side of the small wall portion 13 facing the rim portion 101A is also symmetrical to the groove portion 102 except for the curved portion 102a.
A groove 104 having the same shape as that of FIG.

The apron 12, as shown in FIG.
The washing place 11 of the bathtub 10 is formed so as to cover the side of the tub 10 from the outer end of the rim portion 101A of the bathtub 10 to the washing place 11 below. The apron 12 is formed so as to conform to the outer surface side shape of the rim portion 101A, and is provided on the groove portion 102 side of the bathtub 10 so as to be gradually recessed toward the bathtub 10 side up and down to the position of the washing place 11. 12a are formed, and a flowing water portion R is provided in the concave portion 12a. The flowing water portion R is located below the hollow portion 12a.
Is formed, a drain passage Q communicating with a groove 111 (described later) on the washing place 11 side is formed.

As shown in FIG. 1, the washing place 11 is located at a position one step lower than the rim portion 101 of the bathtub 10.
2 and an outer portion along the left and right ends of the wall mounting portion 15 and the apron 12, a groove portion 110 covered by the groove cover 4 is formed outside the water flowing portion R of the apron 12. At the same time, a groove 111 covered with the groove cover 5 is formed on an outer peripheral portion of the apron 12 along the outside of the flowing water portion R so as to follow the groove 110. The groove 111 serves as a drain for collecting waste water from the washing place 11, and the groove 1
Both width and depth are formed sufficiently larger than 10,
As shown in FIG. 2, a drain trap 5 is attached to the lower surface side of the intermediate portion.

Here, as shown in FIG. 2, the groove cover 4 has one end supported by a step 110a in the groove 110.
The other end is supported by the wall mounting portion 15, and the upper surface is arranged so as to be flush with the upper surface of the floor 112 of the washing room 11 surrounded by the grooves 110 and 111. In this case, a gap S communicating with the inside of the groove 110 is formed between the both sides of the groove lid 4 and the groove 110, and the drainage on the washing place 11 flows into the groove 110 via the gap S. It is poured.
The groove lid 5 is also supported by the step 111a in the groove 111, is arranged so that the upper surface thereof is flush with the upper surface of the floor portion 112, and the outer end of the groove lid 5 excluding the apron 12 side. , A gap S communicating with the inside of the groove 111 is formed with the groove 111.

On the apron 12 side of the groove 111, as shown in FIG. 2, a drainage path Q following the water flowing portion R of the apron 12 is formed so as to communicate with the groove 111. In this case, the size of the entrance of the drainage channel Q is
As shown in FIG. 1, the size is the same as that of the flowing water portion R, for example, the size of the inlet width T is formed to be about 30 mm. In addition, the upper surface of the floor 112 of the washing place 11
It is inclined to descend toward.

The wall mounting portion 14 is formed at the upper end of the small wall portion 13 partly protruding to the washing place 11 side so as to have a water return 14a at the outer end. The wall mounting part 15 is a washing place 1
1 and is formed at a position one step lower than the floor 112, and as shown in FIG.
The upper surface of the lower frame 3a forming the floor part of the floor, the groove lid 4, and the washing place 1
1 between the upper surface of the floor 112 and the floor D1 of the dressing room D;
Almost no step is formed. In addition,
Since the wall mounting portion 15 is formed in the same shape on all three sides on the washing room 11 side, the door frame 3 is attached to the wall mounting portion 1.
5, there is almost no step between the upper surface of the floor 112 of the washing room 11 and the upper surface of the lower frame 3a of the door frame 3 or the floor D1 of the dressing room D.

Next, the operation and effect of the bathtub 1 with a washing place will be described. In the bathtub 1 with a washing place, the wall placing part 15 on the washing place 11 side is formed one step lower than the floor part 112 of the washing place 11. There is no need to provide a step on the floor from D to the washing area 11, and even an elderly bather or the like with weak legs can easily get in and out of the bathroom.

Further, in this bathtub 1 with a washing place, a bather sits on a stool 103 formed at both ends of a rim portion 101 and then puts his / her feet into a basin 100 of the bathtub 10.
Since the feet can be taken out of the water pool 100, the bathtub 1
It is possible to facilitate entry and exit from 0. In this case, for example, when entering the water reservoir 100, the washing place 1
Although it is necessary to move the foot on one side into the water pool 100 so as to pass over the rim 101A of the bathtub 10, a groove 102 for lowering the upper end of the rim 101A is provided in the middle of the rim 101A. As a result, the height of the foot can be reduced accordingly, and the movement of the foot with respect to the basin 100 becomes easy. Further, in this case, a recess 12a is formed on the groove 102 side of the apron 12, and the feet can be placed in the flowing water portion R in the recess 12a. Bathers,
It is possible to sufficiently face the basin 100, and at this point, it is easy to enter and exit the basin 100.

On the other hand, for example, the basin 100 of the bathtub 10
The inside is almost completely filled with water, that is, the bottom surface 10 of the groove 102.
If the bather M enters the sump 100 when there is hot water up to the position 2b, the hot water surface P in the sump 100 moves from the position of the bottom surface 102b of the groove 102 as shown in FIG. For example, the water W rises by a and overflows to the washing place 11 side.

In this case, in this bathtub 1 with a washing place, as shown in FIG. 3, the amount of rise of the molten metal surface P from the upper surface 101a of the rim portion 101 is greater than the depth of the groove portion 102 than a general bathtub. Bathtub 1
The total amount of the overflow water W flowing to the washing place 11 side over the upper surface 101a of the rim portion 101 of the “0” becomes relatively small.
For this reason, the overflow water W that has passed over the upper surface 101a of the rim portion 101 of the bathtub 10 does not accumulate in the washing place 11, and much of the water W flows through the groove lids 4 and 5 on the bathtub 10 side.
0, 111, or into the groove 111 through the drainage channel Q following the water flow section R of the apron 12,
What has reached near the door frame 3 through the floor 112 of the washing room 11 is also poured into the groove 110 on the door frame 3 side via the groove lid 4.

Then, the molten metal surface P is placed on the upper surface 10 of the rim portion 101.
When descending from 1a, the overflow water W to the washing place 11 side becomes
Although it occurs only from the groove 102 of the rim 101A, the groove 1
02 is sufficiently smaller than the length of the rim portion 101A,
The discharge flow rate of the overflow water W from the groove portion 102 is not so large, and the overflow water W flows from the groove portion 102 to the drainage channel Q side through the flowing portion R of the apron 12. For this reason, many of this overflow water W are apron 1
2 that flows into the groove 111 from the drainage channel Q through the flowing water portion R and reaches the vicinity of the door frame 3 through the floor 112 of the washing place 11 is also poured into the groove 110 via the groove lid 4. .

Therefore, in this washing tub 1,
Even when the bather enters the pool 100 which is almost full, the overflow water W generated at this time does not reach the groove 110 on the door frame 3 in a large amount. Even if the size 110 is not enlarged and covered with grating having a large number of drainage inlets, the overflow water W from the bathtub 10 can flow under the door frame 3 with no step between the floor 112 and the like. It does not flow out to the undressing room D side beyond the upper surface of the frame 3a. This is the same even if the door frame 3 is provided at any position of the wall mounting portion 15. Therefore, in the bathtub 1 with a washing place, the groove 110 on the side of the wall mounting portion 15 is enlarged and this is subjected to grating. No need to cover.

In the bathtub 1 with a washing place, the groove 1
The curved portion 10 having a large radius of curvature is located at the corner of the side of the washing area 11 of 02.
Since 2a is formed, the overflow water W that has passed through the groove portion 102 flows sufficiently in the flowing water portion R of the apron 12 and does not greatly jump out to the washing place 11 side. In addition, a groove 104 having substantially the same shape as the groove 102 is formed in a position symmetrical to the groove 102 also in the rim 101B at a position facing the rim 101A of the bathtub 10.
When the basin 100 of the bathtub is covered with, for example, a shutter-type bath lid, the bath lid can be covered without any gap without causing twisting or the like of the bath lid.

It is to be noted that the groove cover 5 is provided with several slits serving as a drainage inflow portion, or a grating having a large number of drainage inflow portions is used in place of the groove cover 5 so that the overflow water W from the bathtub 10 allows the door frame 3 It may not reach further to the side. In this case, a groove 111 covered with the groove cover 5 may be formed on the entire apron 12 side of the washing place 11.

The groove 102 provided on the rim 101A of the bathtub 10 may be provided at one end rather than at the middle of the rim 101A. In this case, a recess 12a is formed on the groove 102 side of the apron 12 to provide a flowing water portion R, and a drainage channel Q communicating with the groove 111 is provided below the flowing water portion R. Of course, the groove 102 is
It may be provided over the entire length of the rim portion 101A except for 03.

Further, when a small step (for example, within 20 mm) is formed between the floor 112 side of the washing room 11 and the upper surface of the lower frame 3a of the door frame 3, the groove 110 on the wall mounting portion 15 side is provided.
The drainage from the washing place 11 does not flow out to the undressing room D side even if it is eliminated.

Further, the corner of the groove 102 on the side of the washing place 11 is not curved, and a large chamfer (for example, 10 m
m or more chamfers).

Further, the depth L of the groove 102 may be made sufficiently large so that even if the bather M enters the bathtub 10 which is full of water, the hot water does not overflow from the area other than the groove 102.

Further, in this embodiment, a description has been given of the bathtub 1 with a washing place in which the washing place 11 and the bathtub 10 are integrally formed. However, the supporting frame of the bathtub is formed integrally with the washing place 11, and the hot water in the bathtub is formed. Even in the case of a bathtub with a washing place in which the reservoir is fitted into the support frame and the rim part is engaged with the support frame, the same effect can be obtained by adopting the same configuration as the bathtub 1 with the washing place. it can.
