DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called barrier-free unit in which a unit bath, in particular, a bathroom washing floor and a floor of an adjacent undressing space have almost no step. About the bus.

[0002]

2. Description of the Related Art Conventionally, a unit bath of this type is designed so that water overflowing from a bathtub or water used in a washing place does not flow into the undressing space side (invade from the undressing space side). A large drainage pit is provided in the room washing area so that water flowing into the washing area can be quickly accommodated and drained. The drainage pit is often formed in a groove along the lower end of the apron of the bathtub or along the opening of the bathroom, and has a sufficient size and depth so that a large amount of water can be immediately accommodated and drained. And have. Although the opening is covered with grating, the grating is necessarily large because the drainage pit is large.

[0003] The drain pit is liable to become dirty, accumulates hair and scale, and is constantly wet, so that mold is liable to be generated, which tends to be unsanitary, and requires frequent cleaning.
However, this type of conventional unit bath washing area has a complicated floor shape due to the above-mentioned drain pit, and as described above, the large drain pit requires a lot of time and effort for cleaning.In particular, many small slits are provided. It was difficult to clean the grating, which had a complicated shape.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has as its object the purpose of having only a minimum required drainage port and making it easy to clean and barrier-free. It is to provide a mold unit bus.

[0005]

In order to achieve the above object, in the unit bath of the present invention, a unit is configured such that there is almost no step between the floor of the washing area and the floor of the adjacent undressing space. In a bus, the washing space and the undressing space are separated by a partition door that can secure watertightness when the door is closed, and the washing room should not have a large drainage pit to prevent the outflow of water from the washing room to the undressing space. I made it. In other words, in the unit bath configured such that the washing floor of the unit bath main body is at substantially the same height level as the floor surface of the adjacent undressing space through the opening formed in the main body,
The unit bath body is provided with a partition door having a watertight structure attached to the opening, and a washing place without a large drainage pit for preventing water from flowing out from the washing place to the undressing space. It is preferable that a small groove communicating with a drainage trap or a drainage pipe by piping is provided in the frame body of the partition door on the dressing room side from the closed position in the frontage direction. At the washing place, at most, a drain outlet having the same size as the drain outlet of the unit bath having a step between the washing floor and the undressing space floor is provided for drainage.

In the unit bath constructed as described above, the outflow of water from the washing place to the undressing space is prevented only by the watertightness of the partition door. Then, even if the water in the washing area passes through the seal part of the partition door for some reason and enters the undressing space side, it is received in the groove provided on the undressing space side of the partition door. The water is drained directly to a drain trap or drain via a pipe. Also, since there is no large drainage pit in the washing area to prevent water from flowing into the undressing space, the shape of the floor of the washing area is simplified, which makes the washing area cleaner and easier to clean.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. A main body of the unit bath, which is generally indicated by reference numeral A in the figure, is formed in a pan shape, and is supported in a floating floor shape by legs (not shown) on the floor of the building frame to form a waterproof pan a constituting a bathroom floor; A required number of panels are erected along the periphery of the waterproof pan a and are connected to each other to form a side wall of a bathroom. A bathtub setting part 1 is provided in one half of the waterproof pan a, and a washing place 2 is provided in the other half.
The bathtub 3 is installed in the bathtub installation section 1, and necessary equipment such as a bath spout 4 and a shower faucet 5 are installed in necessary places.

The unit bath body A has a bathroom side wall facing the washing area 2 and a boundary wall with a undressing space b provided adjacent to the unit bath when the unit bath is installed. An opening 6 for an entrance is formed in a substantially rectangular shape, and a partition door 7 is attached to the opening 6.

The partitioning door 7 is constructed by housing a door 9 in a frame 8 comprising left and right vertical frames 81, 82, an upper frame 83 and a lower frame 84. The frame 8 surrounds the opening 6. Then, it is fitted into and fixed to a door mounting portion 61 protruding from the outer surface of the main body A. Partition door
7 can be any type such as a sliding door type, a hinged door type, and a folding door type.
A folding door type in which a door body 9 is formed by connecting the door members 91 and 92 with a connecting member 12 so as to be freely foldable is used.

Although not shown, one door member 92 of the door 9 is rotatably connected to one vertical frame 82 of the frame 8 by a hinge or the like. On the other door member 91, a door wheel 10 having a circumferential groove-shaped concave portion 10a in a lower frame 91a, a guide piece (not shown) attached to the upper frame 91b, and a guide member (not shown) A guide groove (not shown) is provided on the rail 11 and the upper frame 83 so that the door roller 10 of the door body 9 engages with the guide rail 11 and the guide piece engages with the guide groove. Therefore, when the door body 9 is pulled inward of the main body A, the door body 9 is broken at the connecting member 12, and one of the door members 92 rotates around the hinge as a fulcrum, and is attached to the other door member 91. The sliding door 10 rolls on the guide rail 11 and the guide piece slides in the guide groove to open the door.

The opening 6 to which the partitioning door 7 is attached is formed such that the lower end thereof is substantially at the same level as the floor of the washing area 2 of the waterproof pan a. The lower portion of the door mounting portion 61 formed in a frame shape extends below the level of the washing room 2 floor, and the lower frame 84 of the frame body lower frame is provided between the lower edge surface 61a and the washing room 2 floor. A step is provided which is approximately equal to the thickness or slightly smaller than the thickness. Therefore, the upper end of the frame lower frame 84 and the floor of the washing room 2 are almost at the same level,
There is almost no step between the upper surface of the interior edge 13 provided at the uppermost portion of 84 and extending toward the undressing space B and the floor of the washing room 2.

[0012] The unit bath having the above-described structure, in which almost no step is provided between the floor of the bathroom washing area 2 and the floor of the undressing space B adjacent through the bathroom opening 6, As is well known, in the present invention, in this type of unit bath, water infiltrates the undressing space B side by receiving water overflowing from the bathtub 1 or water used in the washing place 2 and quickly draining it. In order to prevent water leakage, a large drain pit covered with grating, which is usually provided in the washing area 2 of the waterproof pan b, is eliminated.
In the unit bath having a step between the floor of the washing room 2 and the floor of the undressing space B, only the drain 14 which is at most as large as the size of the drain normally provided in the washing is provided. When the partition door 7 is closed, the structure is such that watertightness can be ensured.

That is, as shown in the figure, the partition door is a lower frame of the frame 8.
84 is provided with the guide rail 11 in the frontage direction, and tight material mounting portions 15, 1 are provided on the bathroom washroom 2 side and the undressing space B side, respectively, with the guide rail 11 interposed therebetween.
6 are provided in a state of standing up to face each other. A first tight material 17 which is in contact with or engages with the lower end of the door body 9 in a water-tight manner to constitute a primary waterproof portion is attached to the tight material attaching portion 15 on the bathroom side, and the undressing space B A second tight material 18 which is in close contact with the lower end of the door body 9 on the undressing space B side and forms a secondary waterproof portion is attached to the tight material mounting portion 16 on the side.

Also, a tight material mounting portion on the undressing space B side.
A water return 19 is provided on the outside of the second tight material 18 attached to the portion, and extends slightly upward from the tight material 18. A third tight member 20 is attached to the inside of the barb 19 to form a tertiary waterproof portion. Thus, the door 9
Watertightness between the lower end and the lower frame 84 of the frame 8 is ensured by the primary to tertiary waterproof parts.

Further, in order to ensure watertightness between the door body 9 and the vertical frames 81 and 82 of the frame body 8, the partitioning door 7 has a tight material which is in close contact with the side edge of the door body 9 in the closed state. 21 are provided on the left and right vertical frames 81 and 82 of the frame 8, and a tight member 22 closely contacting the connecting member 12 is used to secure water tightness of the door connecting portion.
The connecting members 12 are provided with tight members 23 that are in close contact with the side edges, respectively.

On the other hand, the indoor edge 13 is provided further on the undressing space B side than the tight material mounting portion 16 on the undressing space B side, and is provided between the tight material mounting portion and the 16 indoor edge 13. A drain 24 is recessed. And the drain
At the bottom of 24, a drain 25 is opened.
Traps to introduce tub drainage and washroom drainage26
Alternatively, a drain pipe is connected to a drain pipe 29 extending from the drain trap 26.
He has been contacted at 27. The upper opening of the drain groove 24 is covered with a groove cover 28 having a slit 28a.

The bottom of the tight material mounting portions 15 and 16 has a groove shape whose bottom is inclined downward to the drain groove 24 side, and is opened at the base of the guide rail 11 and the tight material mounting portion 16 on the undressing space B side. It communicates with the drainage ditch 24 through the drilled water hole 29.

The watertight structure of the partition door 7 described above is an example of the embodiment, and is not limited to the above structure. In short, it is optional to adopt any structure as long as it can seal the space between the frame body 8 and the door body 9 when the door is closed and prevent water in the bathroom from entering the undressing space side.

[0019]

(1) As described above, the present invention relates to a unit bath constructed so that there is almost no step between the floor of a washing room and the floor of an adjacent undressing space.
The floor of the washing area has a simple shape by separating the washing area and the undressing space with a partition door that can secure water tightness when the door is closed, and eliminating the large drainage pit from the washing area to prevent water leakage into the undressing space. This eliminates the need to clean the drain pit and the grating covering the opening of the drain pit unlike the conventional unit bath, so that the bathroom can be easily cleaned. (2) A small groove is provided on the undressing space side of the partition door along the frontage direction, and this groove is connected to a drain trap or a drain pipe by piping, so that it passes through the watertight mechanism of the partition door for some reason. Even if water enters the dressing room side, it flows into the above-mentioned groove and is drained. Therefore, substantial intrusion of water into the dressing room is prevented. And since the above-mentioned groove is enough to receive and drain only a very small amount of water that has penetrated through the watertight structure of the partition door, it is enough to be small, and since water intrusion is rare, it is always wet It is hard to grow mold. Therefore, cleaning of the groove is easy. Further, since the above-mentioned groove is directly connected to the drain trap or the drain pipe by a pipe and is not connected to the washing place, there is no inconvenience that the water in the washing place flows backward.
