Description

[Detailed explanation of the idea] The present invention relates to a bathroom unit.

BACKGROUND ART Conventionally, there have been bathroom units in which a bathtub installation part is formed integrally with a floor part, and a bathtub fitting part is formed in the bathtub installation part, and the bathtub is fitted into the bathtub fitting part.

In this bathroom unit, it is necessary to sufficiently seal the part into which the bathtub is fitted. This water sealing becomes especially important when the bathroom unit is constructed on the second floor.

Conventionally, as shown in FIGS. 1 and 2, a caulking material 4' such as silicone resin is used on the lower end of the frame part 2' of the bathtub 1' and the peripheral edge of the bathtub fitting part 3', or A sealing material such as a soft urethane resin foam containing an adhesive is placed between the back surface of the part 2' and the rising edge 5' of the bathtub installation part A' that protrudes from the peripheral edge of the bathtub fitting part 3'. I was using 6'.

However, when caulking material 4' is used as shown in Figure 1, it takes time to harden, mold may develop and the appearance deteriorates, and furthermore, it may be necessary to repair or replace bathtub 1'. There was a drawback that it was difficult to remove the bathtub 1' when cleaning the bathtub. Furthermore, when a sealing material 6' such as a soft urethane resin foam is used as shown in FIG. The rising edge 5' may become small and the sealing material 6' may not be able to be sufficiently pressed to seal the water, and the sealing material 6' may adhere to the sill portion 2' and the rising edge 5' due to the adhesive, and the bathtub 1 The problem was that it was difficult to remove.

The present invention solves the above-mentioned conventional drawbacks, completely seals the water between the bathtub and the part into which the bathtub is inserted, and allows the bathtub to be easily removed, making it convenient for repairs or replacement of the bathtub. unit.

The gist of the present invention is that a bathtub provided with a frame around its periphery is fitted into a bathtub fitting part formed in a bathtub installation part, and between the frame part and the peripheral edge of the bathtub fitting part. The bathroom unit includes a watertight material and a hard watertight material, and a flexible watertight material is pressed against the hard watertight material.

An example of the present invention will be described below with reference to the drawings.

FIG. 3 is a perspective view showing the overall shape of the bathroom unit. The lower half of the bathroom unit consists of a bathtub installation section A and a washing area B. Furthermore, the upper part of the peripheral wall and the ceiling are assembled to complete the bathroom unit. 4 is a cutaway perspective view of the lower half of the bathroom unit of FIG. 3; FIG. The bathtub installation part A has a bathtub fitting part 1.
is open, and a rising edge 2 stands up from the edge of the opening. Reference numeral 3 denotes a bathtub, and a frame part 4 is provided around the bathtub, and a hanging edge 5 is provided from the outer edge of the frame part 4. The bathtub 3 is fitted into the bathtub fitting part 1 so that the hanging edge 5 of the frame part 4 is hooked to the rising edge 2.

In the bathroom unit of the present invention, a flexible watertight material 6 and a hard watertight material 7 are provided between the frame portion 4 of the bathtub 3 and the peripheral edge of the bathtub fitting portion 1. and,
The flexible watertight material 6 is pressed against the hard watertight material 7.

FIG. 5 is a sectional view showing an example of a flexible watertight material 6 and a hard watertight material 7. The flexible watertight material 6 is made of a material such as a soft polyurethane resin foam, a soft vinyl chloride resin foam, or a rubber foam, and is divided into two parts, each of which has a cut groove 8 on one side. 8 is provided and formed into a frame-like body, and adhesive layers 9, 9 are formed on the other surface. The hard watertight material 7a is made of a metal such as copper or aluminum, or a material such as hard vinyl chloride resin or styrene resin, and is formed into a frame-like body with a vertically elongated cross section. The hard watertight material 7a is fitted into the cut grooves 8, 8 of the soft watertight materials 6a, 6a. Such watertight material 6a,
6a, 7a to the bathroom unit, while the hard watertight material 7a is fitted onto the soft watertight material 6a, 6a, apply an adhesive layer to the periphery of the bathtub fitting part 1 as shown in FIG. Glue 9. Next, as shown in FIG. 8, the bathtub fitting part 1 is fitted into the bathtub 3, and the adhesive layer 9 is adhered to the back surface of the frame part 4. The weight of the bathtub 3 compresses the flexible watertight materials 6a, 6a, and the hard watertight material 7a presses the flexible watertight materials 6a, 6a to completely seal the water. As described above, the construction of the watertight material is extremely easy, and the structure of the watertight material is also simple, so manufacturing is easy and an increase in cost can be suppressed.

Using flexible watertight material 6a and hard watertight material 7a,
Since the flexible watertight material 6a is pressed against the hard watertight material 7a to achieve water sealing, complete water sealing is achieved even if the compressive force due to the weight of the bathtub 3 is small.
The space between the peripheral edge of the bathtub fitting part 1 and the frame part 4 of the bathtub 3 is narrow, and the rising edge 2 is small, or the rising edge 2 is narrow.
Water leakage can be prevented even if there is no water leakage. In addition, the flexible watertight material 6a prevents the rising edge 2 of the bathtub fitting part 1 and the hanging edge 5 of the stile part 4 from hitting the other person.

Since the flexible watertight material 6a and the hard watertight material 7a are not bonded and therefore not joined between the bathtub 3 and the bathtub fitting part 1, the sill part 4 of the bathtub 3 as shown in FIG. The bathtub 3 can be removed while the upper flexible watertight material 6a is adhered to the bathtub 3. However,
The bathtub 3 can be replaced or the piping below the bathtub installation part A can be repaired.

The cross-sectional shape of the hard watertight material 7 can be changed in various ways.
Further, the cut groove 8 of the flexible watertight material 6a stably holds the hard watertight material 7a. As shown in Figure 5, a flexible watertight material 6 is used before construction of the bathroom unit.
a, 6a and the hard watertight material 7a can be combined, making handling convenient.

Fig. 10 shows an example in which a hard watertight material 7b with a square cross section is used, and if it can be held between the flexible watertight materials 6b, 6b, there is no need to provide a cut groove 8 in the flexible watertight materials 6b, 6b. . Of course, in order to hold the hard watertight material 7b more stably, flexible watertight materials 6b, 6 are used.
A cut groove 8 can also be provided in b. FIG. 11 shows another embodiment of the present invention. A flexible watertight material 6c is adhered to the back surface of the frame portion 4 of the bathtub 3, and an adhesive layer 9 is formed on one side of a hard watertight material 7c having an E-shaped cross section, and is adhered to the peripheral edge of the bathtub fitting portion 1. The flexible watertight material 6c is pressed against the hard watertight material 7c to effectively seal water. If a hard watertight material 7c is used, it must be adhered to the peripheral edge of the bathtub fitting portion 1 to prevent water from leaking. A cut groove is provided in the flexible watertight material 6c, and the flexible watertight material 6c and hard watertight material 7c are combined as shown in FIG. 5 and attached to the peripheral edge of the bathtub fitting part 1 as shown in FIG. You can do it as you like.

FIG. 12 shows yet another embodiment. The hard watertight material 7d is integrally provided as a protruding strip from the periphery of the frame portion 4 of the bathtub 3 and the bathtub fitting portion 1. Of course, the hard watertight material 7d is inserted into the bathtub 3 as shown in Fig. 11.
Alternatively, it may be adhered to the peripheral edge of the bathtub fitting part 1 as a separate body. The flexible watertight material 6d is formed into a band-shaped body, and is sandwiched between the hard watertight materials 7d and pressed to form a water seal.

The flexible watertight material 6 and the hard watertight material 7 do not need to be shaped into a frame-like body as shown in FIG. In some cases, the flexible watertight material 6 and the hard watertight material 7 may be divided into a plurality of pieces.

The flexible watertight materials 6' and 6'' shown in FIGS. 13 and 14 have a part cut out and do not form a frame-like body. 3. It is used by being located in the part of the bathtub fitting part 1 facing the washing area B. By forming the peripheral edge of the bathtub fitting part 1 with a gentle slope through which water flows toward the washing area B, in the event that hot water leaks from the watertight materials 6 and 7, the hot water will flow to the rising edge 2. The water is stopped and can be poured into the washing area through the notched portions of the flexible watertight materials 6', 6''.

Because the bathroom unit of the present invention has the above-described configuration, it can be used when the space between the rim of the bathtub and the peripheral edge of the bathtub fitting part is narrow and conventional sealing materials cannot be used, or when compression is caused by the weight of the bathtub. Even if the force is small, a complete water sealing effect can be obtained, and it is easy to install and handle.After the bathtub is installed, the rim of the bathtub will hit the periphery of the bathtub fitting, causing noise. There is nothing to do.

Furthermore, in the bathroom unit of the present invention, when it is necessary to repair piping or replace the bathtub, the bathtub can be removed from the bathtub fitting part and repair work can be carried out freely.
