Description

  The present invention relates to a unit bath installed in a state where a separately formed waterproofing pan for a washing place and a bathtub are adjacent to each other, and more particularly, to a unit bath capable of draining water leaking from the back side of the bathtub onto the washing floor.

  There is a unit bath of a type in which a bathtub, a waterproof pan for a washing place, and a bath apron are divided, and a wall is installed on a rim portion of the bathtub. In such a unit bath, a waterproof pan for bathtubs is not installed in the lower part of the bathtub. Therefore, in the unlikely event that water leaks at the connecting portion between the bathtub and the additional cooking adapter, water will leak to the building floor. Therefore, as described in Patent Document 1, it is necessary to attach a water receiving member to a location where water leakage easily occurs on the back of the bathtub and drain the water received by the water receiving member onto the washing floor.

In addition, when the structure that can add the waterproofing pan for the bathtub as an option is considered for the specification that usually does not have the waterproofing pan for the bathtub at the bottom of the bathtub, the water collected in the waterproofing pan for the bathtub can be easily washed. It is preferable to be able to drain on the floor.

  As shown in FIG. 1, the unit bath of this embodiment includes a bathtub 1 installed on a bathtub base, a waterproof pan 2 for a washing place installed at a position adjacent to the bathtub 1 on the washing base, and a large bath apron. 3 and a small bath apron 4 and a pair of connecting members 5a and 5b are divided and formed. Bathtub 1 has inner tank part 1a which can store bathtub water, and rim part 1b formed in the upper edge part perimeter of inner tank part 1a. It is a unit bath in which wall installation parts for installing wall panels are formed on three sides of the rim part 1b formed on the upper edge of the bathtub 1 except for the side adjacent to the waterproof pan 2 for the washing place. In this embodiment, the waterproof pan for bathtubs is not installed in the lower part of the bathtub 1.

  The unit bus as described above has an advantage that it has a rational and simple configuration and is therefore low in cost. In addition, there are merits such as on-site transportability, handling during installation, ease of maintenance, and easy response to the user's high-class feelings.

  On the upper surface of the waterproof pan 2 for the washing place, a downward slope is formed toward the drain outlet portion where the drain trap is installed. The water that has flowed down onto the waterproof pan for the washing place is guided to the drain outlet and discharged to the outside of the bathroom through the drain trap. Further, a bank part 2a for returning water is formed on the side of the bathtub 1 side of the waterproof pan 2 for the washing place. Furthermore, the recessed part 2b formed one step lower is formed in the waterproofing pan 2 for washing places in the both ends of the bank part 2a. In addition, it forms so that the water return formed higher than the recessed part 2b may remain in the bathtub 1 side rather than the recessed part 2b.

  At the end on the back side of the bathtub rim 1b located on the side of the waterproof pan 2 for the washing place, there are formed a front hanging portion that is suspended downward and a rib portion that is also suspended from the front hanging portion. .

  As shown in FIG. 2, a pair of connecting members 5 a and 5 b are attached so as to connect the back side of the rim part of the bathtub 1 and the upper part of the bank part of the washing place waterproof pan 2. The pair of connecting members 5a and 5b are connected in a watertight manner at both ends of adjacent sides of the bathtub 1 and the waterproof pan 2 for a washing place. More specifically, the upper ends of the connecting members 5a and 5b are inserted between the front hanging portion and the rib portion of the bathtub 1, and the lower ends of the connecting members 5a and 5b are the waterproof pan 2 for the washing place. It is attached in the state fitted in the recessed part 2b formed in the bank part 2a.

  Further, as shown in FIGS. 2 and 3, one connecting member 5 a is provided with a through hole 7 for guiding a drain pipe portion 6 to be described later, and the drain pipe portion is fixed by a fixing band 8 from the bathtub 1 side. The ends of 6 are connected in a watertight manner. This through hole 7 is a hole for connecting the back side of the bathtub 1 and the waterproof pan 2 for the washing place with the connecting member 5a interposed therebetween.

  The front surface of the pair of connecting members 5a and 5b on the side of the waterproofing basin 2 for the washing area, the front surface of the basin 2a on the side of the waterproofing area 2 for the cleaning area, and the front surface of the rib 1 in the bathtub 1 It is arranged so as to be a flat frame-like plane. By fitting a bath apron fitted with a watertight packing formed in a frame shape against this frame-shaped plane, water is taken off so that water from the waterproof pan 2 side for the washing place does not leak to the back of the bathtub. Yes. In addition to the pipe hole 7, the connecting member 5 a has a drain pipe passage 17 for bringing a water supply pipe and a hot water supply pipe rising from the back side of the bathtub 2 to the waterproof pan 2 side for the washing place from the back side of the bathtub 1. Is formed. In addition, the above-mentioned through-hole 7 is formed in the outer peripheral side rather than the watertight line formed in the frame shape of the bus aprons 3 and 4. That is, the water that flows into the through hole 7 from the drain pipe 6 is drained onto the waterproof pan 2 for the washing place.

  Moreover, in the unit bath by this embodiment mentioned above, since the bathtub waterproofing pan is not installed in the lower part of the bathtub 1, the connection part of the bathtub 1 and the additional cooking adapter as shown in FIG. In the unlikely event that water leaks at the connection part or the connection part between the building side and the unit bath side in the water supply hot water startup drain pipe (not shown), the water will leak to the building floor. Therefore, it is necessary to attach the water receiving member 9 to a place where water leakage easily occurs on the back of the bathtub 1 and drain the water in the water receiving member 9 onto the waterproof pan 2 for the washing place.

  Therefore, in the unit bath according to the present embodiment, the water receiving member 9 and the through-hole 7 formed in the connecting member 5a are flexible in order to drain the water from the water receiving member 9 onto the waterproof pan 2 for the washing place. It is connected in a watertight manner by a drain pipe portion 6 formed of a material having

  Thereby, the water from the water receiving member 9 passes through the drain pipe portion 6 that is watertightly connected to the hole formed in the water receiving member 9, to the through hole 7 of the connecting material 5 a that is watertightly connected. It is guided and drained from the through hole 7 formed in the connecting member 5a onto the washing place waterproofing pan 2. In addition, it is necessary for the whole drain pipe part 6 and the through-hole 7 of the connection material 5a to be formed in a lower position than the overflow surface of the water receiving member 9. More preferably, the drain pipe portion 6 is attached to the lower surface of the water receiving member 9, and the drain pipe portion 6 is preferably arranged so as to always incline downward toward the through hole 7 of the connecting member 5a. By doing in this way, since water does not remain in the drain pipe part 6 and the water receiving member 9, it is preferable.

  Thus, since the water on the back side of the bathtub 1 is drained on the washing place waterproof pan 2, the user can notice that water leaks on the back side of the bathtub 1. For example, in the case where the water from the water receiving member 9 is guided into the drain trap, the user cannot notice that water leaks on the back side of the bathtub 1. Moreover, in the form connected to the drain trap, if the water in the drain trap flows into the drain pipe, the drain pipe may be clogged with dirt, but in this embodiment, the drain pipe 6 is clean. It can be used in any state. Further, cleaning is possible by simply removing the bus aprons 3 and 4, and there is a merit in that a large-scale operation such as dismantling the structure is not required when replacing.

  Further, since the surface of the wash basin waterproofing pan side 2 of the connecting member 5a that is watertightly connected to the drain pipe 6 is covered by the bath apron 3 and 4, it cannot be visually observed from the wash basin waterproof pan side 2. For this reason, since the through-hole 7 etc. are also hidden, the designability is not impaired.

Next, a unit bus according to a second embodiment of the present invention will be described.

It is. In the case of such a specification that a bathtub waterproof pan can be added as an option, the bathtub waterproof pan does not bear a part of the structure of the bathroom unit.

  In this case, since the bottom of the bathtub waterproof pan is formed at a position lower than the through hole 7 formed in the connecting member 5a, the attachment position of the drain pipe portion 6 to the bathtub waterproof pan is for the bathtub. It will be formed on the side of the waterproof pan. That is, when water of a predetermined level or more of the waterproofing pan for bathtubs has accumulated, the water is drained from the through hole 7 onto the waterproofing pan 2 for the washing place through the drain pipe portion 6.

  According to the present embodiment, it is possible to drain water in the bathtub waterproof pan without providing a dedicated drain trap on the bathtub waterproof pan or joining the drain trap attached to the waterproof pan 2 for the washing place. It becomes.

  In addition, even if it is combined with a special trap for the bathtub waterproofing pan or a drain trap attached to the washing place, even if these are clogged, water leaks from the back of the bathtub 1 to the building floor side. It becomes possible to prevent.

  As described above, even when a bathtub waterproof pan is added as an option, the bathtub waterproof pan and the through hole 7 of the connecting member 5a are connected in a watertight manner with the same structure as in the first embodiment. The water in the waterproof pan can be drained onto the waterproof pan 2 for the washing place.
