Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub installed and used in a general house or the like, and more particularly to a bathtub capable of adjusting a water level of hot water in the bathtub.

[0002]

2. Description of the Related Art Conventionally, the inner volume of a bathtub used in general households is structurally constant, and the amount of hot water in the bathtub is substantially constant. On the other hand, in each family,
Due to the family structure of bathing, children from small children to adults with large physiques are mixed, but it is not possible to pour hot water into the bathtub according to the volume of each person's body, and in large bathtubs, a large amount corresponding to the bathtub. It is generally used with hot water.

[0003]

However, as described above, in the conventional bathtub, the volume of hot water required cannot be adjusted according to the physique of each person, and the bathtub is always oversized. Since there is no choice but to pour hot water into it, the amount of hot water used is wasted, which is uneconomical.

For example, Japanese Utility Model Laid-Open No. 6-13672 describes a cushion cover for a bathtub which is provided with a cover made of a soft material on the inside of the bathtub so as to have a cushioning property. However, the purpose is to give the inner surface of a hard bathtub cushioning, and it is not a device that can solve the above problems, but its purpose is different.

The present invention has been made by paying attention to the above-mentioned problems of the prior art. The object of the present invention is to solve these problems and allow a bath with a minimum amount of hot water. Further, the present invention provides a bathtub which has an effect of preventing a temperature drop of hot water due to its heat insulating property.

[0006]

In the bathtub of the present invention, a stretchable membrane is attached to the inner wall surface of the bath, the periphery of the membrane is sealed, and fluid is supplied from an inlet provided in the membrane. Is injected and sealed.

As the material of the film body, synthetic rubber or the like having excellent elasticity and durability is preferably used. Further, the film body is provided with an injection port capable of injecting a fluid such as air or water so that the fluid can be taken in and out and the injection amount can be freely adjusted.

The film body is attached to the inner wall surface of the bathtub by a fusion method or a sticking method using an adhesive. Further, it is preferable to provide vertical and horizontal partitions on the film body so that the respective parts communicate with each other, which is effective in preventing a large local expansion.

Further, the film body may be a flat bag-like one, and one side may be attached to the inner wall surface of the bathtub.

[0010]

In the bathtub of the present invention, as described above, the stretchable film body is attached to the inner wall surface of the bathtub in a state in which the periphery is sealed, and a fluid such as air is supplied from the inlet provided in the film body. Is injected and sealed inside, so by adjusting the amount of injected air, the volume of the bathtub can be adjusted according to each person's physique, and the level of the hot water (water level) can be adjusted. It is possible to bathe with a certain amount of hot water, and it is possible to improve economic efficiency. In addition, a heat insulating layer formed by a fluid such as air is formed between the inner wall surface of the bathtub and the film body, which has the effect of preventing the temperature of the hot water from decreasing, and there is less need for additional heating. It is also expected to have an economic effect that it will be completed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of the bathtub of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. In the bathtub 1 of the present invention, the left and right which can be expanded and contracted to the inner wall surface 11 of the bathtub 1,
A sheet-like membrane body 2 made of synthetic rubber, which is divided into upper and lower parts
However, it is attached in a state in which the periphery is attached and sealed.

The film body 2 provided on the inner wall surface 11 of the bathtub 1 is partitioned in the left-right direction and the up-down direction in order to prevent a large local expansion. Each of the film bodies 22 is constituted by.

Further, each of the film bodies 21 in the left-right direction is provided with a partition portion 2.
The fluid such as the injected air is communicated with each other at a, and the partition portion 2a
It is fixed to the inner wall surface 11 of the bathtub 1 by using a water-resistant adhesive.

Reference numeral 3 is an inlet for a fluid such as air. In this embodiment, the inlet 3 is provided in each row so that the fluid such as air can be easily injected. As shown in the detailed structure of FIG. 3, the inlet 3 is provided with a sealing plug 31, which is a structure that can be easily attached and detached so that the amount of air enclosed can be adjusted freely.

Further, for example, the air injected from the injection port 3 is made to uniformly flow into each of the membrane members 21, 22, 23 in the row via the communicating portion of the partition 2a.

As shown in FIG. 3, when air is sealed (sealed by the sealing plug 31), a similar air layer 4 is formed on each of the film bodies 21, 22, 23. Therefore, the total volume of each partition 2a of the air layer 4 formed in the bath 1 contributes to the rise of the water level of the hot water in the bath.

That is, by increasing or decreasing the volume of the air layer 4 according to the volume of the person's physique, the amount of hot water filling the bathtub 1 can be adjusted and the level of the hot water can be adjusted. It is possible to bathe with a certain amount of hot water, and it is possible to improve economic efficiency.

By enclosing a fluid such as air having a low thermal conductivity between the inner wall surface of the bathtub and the film body, a heat insulating layer is formed by the air, and the temperature of the hot water is lowered. It has the effect of preventing heat generation, and is expected to have an economic effect such that the need for reheating is small.

In the bathtub of the present invention, in the above embodiment,
The sheet-shaped film body 2 is partitioned into the inner wall surface 11 of the bathtub 2a.
Although the structure is provided and the structure is directly attached, the film body 2 may be configured in a bag shape in which the partition 2a is provided at a required position.

Further, each film body 21, 2 between each partition portion 2a
The communication of 2, 23, etc. may be provided in the vertical direction instead of being provided in the left-right direction as in the above embodiment, and accordingly, the inlet port 3 for air or the like may be provided so as to be communicated in the vertical direction.

[0021]

In the bathtub of the present invention, as described above, the stretchable film body is attached to the inner wall surface of the bathtub in a state in which the periphery is sealed, and air or the like is supplied from the inlet provided in the film body. Since the fluid of is injected and sealed inside, the volume of the bath can be adjusted according to each person's physique by adjusting the amount of injected air, and the level of the water (water level) can be adjusted. It is possible to take a bath with the minimum amount of hot water, and it is possible to improve economic efficiency. That is, the amount of water used and the amount of heat sources such as gas and electricity used can be reduced, which is useful for resource saving.

Further, since a heat insulating layer formed by a fluid such as air is formed between the inner wall surface of the bathtub and the film body, it has an effect of preventing the temperature of the hot water from lowering, and it is necessary to reheat it. It is also expected to have an economic effect of requiring less.

Further, by using synthetic rubber or the like for the film body, there is an anti-slip effect in the bath tub, which enables safer bathing and secures cushioning properties as compared with the hard inner surface of the conventional bath tub. You can enjoy a more comfortable bath. Therefore, it is suitable as a bathtub.
