Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art As shown in FIG. 10, in a unit bath which is a prefabricated bathroom and has a structure in which a bathtub is placed on a waterproof floor, drainage in a washing place side and drainage in a bathtub are usually performed.
And water collected on the floor under the bathtub is collected in one concave portion called a drainage pit portion 107, and the drainage port 1 located therein is collected.
From 14, the water is discharged outside through a drain trap 109. The drain port 114 is covered by the lid member 106 above the drain port 114 so that the drain port 114 is not visible from the floor 101 on the washing side, thereby improving the design. A convex portion 105 called a bank is formed along the longitudinal direction of the bathtub at the boundary between the bathtub side floor 102 and the washing place side floor 101 of the waterproof floor, and separates the edge between the bathtub side floor 102 and the washing place side floor 101. ing. This is because, among the hot and cold water used in the bathroom, miscellaneous wastewater mixed with soap at the time of washing and hair washing performed in a washing place flows into the bathtub side floor 102 (below the bathtub), and the bathtub side floor 102 becomes dirty. It is formed for the purpose of preventing.

[0003] The drain pit 107 of the bathroom unit described above.
Is formed by cutting off the bank portion 105 in such a manner that it communicates with both the washing floor 101 and the bathtub floor 102 at this boundary. Since the drainage pit portion lacks the bank portion 105, miscellaneous drainage in the washing area easily flows into the bathtub side. To prevent this, the drainage hole 114 of the drainage pit portion is used.
The portion to be attached is made deeper than the bottom surface of the bathtub-side floor 102, and due to the water return step 108a formed, consideration is taken so that miscellaneous drainage from the washing place does not inadvertently flow into the bathtub-side floor 102. It had been.

However, in recent years, with the advent of the aged society, the reduction of steps in the bathroom has become the basic specification of the product, and as a result, the total height of the waterproof floor has been reduced to achieve this. Deep drain pit 107
Are difficult to physically form, and the step between the mounting surface of the drain port 114 and the bottom surface of the bathtub-side floor 102 tends to gradually decrease. Further, in recent products that have been made thinner, the mounting surface of the drainage port 114 has a lower bathtub side floor 10.
Those that are located higher than the bottom of 2 are also on the market.

[0005] In the conventional unit bath for the elderly, which must take the above-described form, the bathtub side floor 102 and the washroom side floor 1 due to the water return step 108 a of the drain pit 107 are provided.
Since the margin with 01 is not sufficiently formed, the wastewater used in the washing place easily flows into the bathtub-side floor 102 via the drainage pit 107, and there is a problem that the lower part of the bathtub is easily stained.

As one method for solving these problems, a drain port on the floor on the washing side and a drain port on the floor on the bathtub side are separated, and the drain on the washing side is drained from the drain on the washing side, and the bathtub side is on the bathtub side. Drainage from drainage outlets, two-system drainage, eliminating breakage of the bank together, completely separating the washroom floor and bathtub side floor, and drainage from the washroom floor flows into the bathtub side floor. There may be a way to avoid this. However, when this measure is taken, there is no approach route around the bathtub-side floor drain outlet, so that cleaning of the bathtub-side drain outlet becomes substantially impossible. Considering the cleanliness of the bathroom, an "approach from the washroom side" is indispensable, and the bank must be cut out in some way to secure the route.
The problem that miscellaneous wastewater from the washing yard flows into the floor pan on the bathtub side from that part and becomes dirty similarly occurs.

[0007]

SUMMARY OF THE INVENTION In view of the above, the present invention has been made in consideration of the above-described circumstances, such as when the height of a floor body is reduced, or when a water return step in a drain pit is not sufficiently formed. In order to prioritize the reduction of steps, the floor on the bathtub side must be formed lower than the floor on the washroom side, and even in bathrooms that require a drain port on the bathtub side, maintainability is sacrificed. The purpose of the present invention is to provide a unit bath having a sanitary drainage structure in which the floor of the bathtub and the floor of the washing room can be firmly cut without causing hot water after use in the washing room to flow into the floor of the bathtub. And

[0008]

According to the first aspect of the present invention, there is provided a waterproof floor provided with a bathtub mounting portion, a wall panel constituting a wall portion, and a waterproof panel mounted on the wall panel. In a bathroom unit comprising a ceiling panel to be fixed and fixed, including a drainage port at the boundary between the floor on the bathtub mounting side and the floor on the washing side, and a drainage pit communicating with both of them,
A partitioning material is arranged at the boundary between the washing pit side and the bathtub mounting side of the drainage pit portion, and a watertight material is provided at least in a portion of the partitioning material in contact with the floor drainage pit portion, so that the bathtub side floor and the washroom side floor are watertight. It is characterized in that it is sectioned in a specific manner.

In the present invention, even after the miscellaneous wastewater from the washing place is collected along the drainage pit portion (drainage port) along the drainage slope attached to the surface of the washing place, it is obstructed by the partition member with the watertight material. Does not flow into the bathtub side, and as a result, the floor on the bathtub side is less likely to become dirty.

According to a second aspect of the present invention, in the case of the first aspect, the partition member is detachably fitted to a floor drain pit portion. is there.

According to the present invention, when cleaning the floor of the bathtub side around the drainage pit or performing maintenance, an approach path for maintenance can be secured from the washing place side by removing the partition member, thereby sacrificing maintainability. An effective water partitioning effect can be obtained without reducing the water content.

The third aspect of the present invention is the first aspect.
In the case of the invention described in ~ 2, the partition member attached to the floor in a semi-fixed state with a watertight material is provided with a fitting means capable of easily fitting a lid member covering and covering the partition material and the drain port. It is a feature.

According to the present invention, the partition member and the drain port are covered from above by the partition member fitted into the drain pit portion of the floor with a certain fitting force while bending the water-tight member to obtain a water-tight structure. By simply fitting the lid member,
The lid member is fitted to the floor via the partition material, so that even if a large amount of water flows into the drain port, the lid member does not rise and drift, and also suppresses subtle rattling of the lid member. it can.

The invention described in claim 4 of the present invention is claim 1.
In the case of the inventions described in the above-described embodiments, the upper end of the partition member for partitioning the drainage pit portion of the bathroom unit in a watertight manner is higher than the drainage port installation surface on the washing side, and the convex bank separating the washing side and the bathtub side. It is characterized by being formed lower than the upper end of the part.

According to the present invention, the upper end of the partition is made higher than the mounting surface of the drain port on the side of the washing basin so that miscellaneous drainage from the washing basin does not easily flow into the floor on the tub side, and at the same time, the upper end of the partition is made convex. Because it was formed lower than the bank, a large amount of hot water (such as overflow of the bathtub) suddenly flowed into the bathtub side floor, and when the water level of the bathtub side floor suddenly rose, the water was first overflowed from the partition material to the washing area side. The water level on the bathtub side can be quickly lowered.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a drain port of the present embodiment, FIG. 2 is a sectional view of the drain port of the present embodiment, FIG. 3 is a perspective view of the drain port of the present embodiment viewed from the bathtub side, and FIG. FIG. 5 is a perspective view from the back of the drain port lid member, FIG. 6 is a drain port cross-sectional view showing a simple fitting state of the lid member and the partition plate, and FIGS. FIG. 10 is a detailed view showing a simple fitting means with a partition plate, and FIG. 10 is a perspective view showing a structure around a drain port of a conventional bathroom.

In the present invention, as shown in FIG. 1, a floor is constituted by a washroom-side floor 1, a bathtub-side floor 2, and a bank 5 formed at the boundary between the floor and the floor, which are made of reinforced plastic or the like. As in the conventional example, a drain pit 7 is provided so as to divide the bank 5, and a drain 14 is disposed therein. A bathtub 3 is placed on the bathtub-side floor 2, and the floor 1,
A wall panel (not shown) is erected on the outer peripheral portion of the device 2. A ceiling panel (not shown) is stacked on the wall panel to constitute a bathroom unit.

As shown in FIG. 3, in this embodiment, the bathtub-side floor 2 is located at a position lower than the level of the drain pit 7, and the step 8b caused by the step 8b is the same as that of the conventional bathroom shown in FIG. The height relationship between the floor 108a and the floor on the washroom side / floor on the bathtub side is exactly opposite. This is the case when configuring a bathroom with a low step specification required for products for elderly people in recent years,
This is because it is necessary to reduce the overall height (total thickness) of the waterproof floor, and the height of the bathtub-side floor 2 is reduced to satisfy the requirement of reducing the overall height of the entire floor.

A bathtub-side floor drainage elbow 13 is provided on the bathtub-side floor 2 and is connected to the side surface of the drainage trap 9 main body. The bathtub-side floor drainage elbow 13 has a drainage fitting 19 for the bathtub 3 inserted therein.
, And is guided to the drain trap 9 body to be drained. In addition, overflow water and the like in the bathtub that has flowed into the bathtub-side floor 2 are guided to the main body of the drain trap 9 from the drain hole 17 of the bathtub-side floor drainage elbow 13 and drained in the same manner as the bathtub drainage. This drain hole 1
7, the water in the bathtub is filled by the water pressure when the bathtub is drained.
Is usually equipped with a check valve 18 in order to prevent overflow from occurring.

Normally, when a check valve or the like is provided on the floor on the bathtub side as described above, it is necessary to periodically perform maintenance of this part. By notching the part of the bank, it is possible to approach from the washing place side during maintenance. Also, without using a check valve, a special trap is also provided on the floor on the bathtub side, and the drainage on the washing tub side and the bathtub side is performed by separate systems using two traps. Since regular maintenance is required, the conditions such as the installation position of the bathtub side trap to secure the approach path to this part and the necessity of notching the bank part are implemented by using the check valve. This is the same as in the example.

At the boundary between the drain pit portion 7 and the bathtub side floor 2, a partition member 11 having a soft (for example, rubber) watertight material 12 is provided around the boundary between the bathtub side floor 2 and the drain pit as shown in FIG. It is fitted in a boundary portion with the portion 7 in a watertight and simple fitting state, and restores the water stopping and edging functions of the bank portion 5 which has been lost by the drainage pit portion 7.

A cover member 6 is installed above the drain pit 7 so as to cover it, and as shown in FIGS. 5 and 6, the back surface of the cover member 6 and the surface of the partition member 11 are respectively provided. Is provided so that the lid member 6 can be easily fitted to the partition member 11. In addition, this lid member is generally called a trap cover.

FIGS. 7, 8 and 9 show an example of locking means by simple fitting of the lid member 6 and the partition member 11. FIG. FIG. 7 shows that a bush 20 made of a soft material such as rubber is attached to a convex portion 15 a formed on the front surface side of the partition member 11, and a protrusion 16 a formed on the back surface of the lid member 6 is fitted into the bush 20. Thus, the lid member 6 and the partition member 11 are simply connected. 8, similarly to FIG. 7, a chrysanthemum seat having a split is formed integrally with a projection 15 b formed on the surface of the partition member 11, and a projection 16 b is formed on the back surface of the lid member.
The cover member 6 and the partition member 11 are easily fitted by inserting the chrysanthemum seat portion b while elastically deforming the same. FIG. 9 shows that a locking piece 16c is formed on the back surface of the lid member 6,
By providing a receiving member 15c corresponding to the surface of the partition member 11, the lid member 6 and the partition member 11 can be easily fitted. The simple fitting means is not limited to the illustrated one as long as it is a normally conceivable locking means.
For example, a hook-and-loop fastener may be used.

Next, the operation of the embodiment of the present invention will be described. The embodiment of the present invention shows an example in which the total height of the floor is reduced and the bathtub-side floor 2 is lower than the drain pit 7, but the bathtub-side floor 2 is lower than the drain pit 7. Even if it is not lower than that, if the effective water return step cannot be formed, the operation and effects described below are the same.

The used wastewater used in the washing floor 1 flows along the drainage gradient, is collected in the drainage pit 7, and is then drained out from the drainage port 14. A considerable amount of water comes to the drain pit 7 like the prior art. In this case, since the bathtub-side floor 2 communicating with the drainage pit 7 is lower in height than the drainage pit 7, the gray water easily flows into the bathtub-side floor 2 as it is. In the present invention, the drainage pit 7
Since the boundary between the tub and the bathtub-side floor 2 is water-tightly partitioned by the partition member 11, miscellaneous wastewater collected in the drainage pit 7 does not flow into the bathtub-side floor 2. In addition, the upper end portion 11b of the partition member 11 for partitioning the drain pit portion 7 of the bathroom unit in a water-tight manner is higher than the mounting surface of the drain port 14 on the washing side, and a convex bank portion separating the washing side and the bathtub side. 5 is formed lower than the upper end 5a, so that the drainage from the washing place hardly flows into the bathtub-side floor 2, and a large amount of hot water (such as overflow of the bathtub) flows into the bathtub-side floor 2 at a stretch. Even if the water level rises, the water level at the bathtub side can be immediately lowered by overflowing from this portion to the washing side first. Naturally, an effective effect cannot be obtained unless the partition member 11 is in a watertight state with respect to the floor.
A soft (for example, rubber) watertight material 12 is disposed at least around the partition member 11 in contact with the floor, and is fitted to the floor boundary while flexing the soft portion, thereby providing a high degree of watertightness and simple fitting to the floor. A match is made.

The drain port portion 14 and the partition member 11 are covered with a cover member 6 so as to cover both of them from the upper portion, and are finished almost integrally with the floor surface in design. Partition material 11
A simple fitting mechanism 1 is provided between the upper part 11a of the
5 and 16 are provided, and the lid member 6 is covered while being fitted to the partition member 11. That is, since the lid member 6 is easily fitted to the partition member 11 which is simply fitted to the floor, the lid member 6 is simply fitted to the floor indirectly, and a large amount of hot and cold water is drained. Even when it flows into the mouth pit portion 7, the lid member 6 is not free and does not float on the water and drift. In addition, rattling of the lid member 6 is also suppressed.
