Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a bathtub, and more specifically, it relates to a method for manufacturing a bathtub in which the color of the bathtub can be easily changed and the user can enjoy changing bathing.

[0002]

2. Description of the Related Art Heretofore, there has been no such bathtub itself, let alone a method for manufacturing the bathtub.

[0003]

Originally, since the bathtub is a structure which is a part of the constructed building, it is difficult to replace it frequently. Even if it is replaced, the bathtub can be replaced during the replacement work. In general, the bathtub initially installed is often used as it is because of problems such as being unusable and costly.

On the other hand, taking a day's fatigue removes fatigue from the day, recovers from fatigue and promotes health, and has a high effect of changing the mood. In order to fully utilize these effects, an optimal environment for the bathroom is formed. Things can be extremely important. In particular,
As a factor that influences the mood of taking a bath, the colors of the bathroom and the bathtub in particular are closely related.

However, due to the above-mentioned circumstances, the color of the bathtub installed at the time of building the building is not changed unless the bathtub is replaced.
It is difficult to change, let alone change the color of the bathtub to your liking depending on the mood of the day.

Therefore, an object of the present invention is to provide a method of manufacturing a bathtub in which the color can be freely changed while the bathtub is installed.

[0007]

In order to achieve this object, a characteristic means of the method of manufacturing a bathtub according to the present invention is that a transparent tube is laid in the concave mold for bathtub formation along the inner surface of the mold, The transparent tube group is sandwiched between the concave mold and the convex mold for bathtub molding, and the transparent tube group in the sandwiched state is integrally welded in a shape along the surface shapes of the both molds. There is a place to do it.

[0008]

According to the characteristic means of the bathtub manufacturing method of the present invention, the transparent tube is laid along the inner surface of the mold for forming the bathtub, and the transparent tube group is formed into the convex mold for forming the bathtub. It is sandwiched between the concave formwork by a frame, and the transparent tube group in the sandwiched state is integrally welded in a form along the surface shape of the both formworks, so that the inside of the bath skeleton can be seen from the outside. It is possible to easily form a space that can communicate with each other. For example, if the color liquid is injected into the space, the color of the color liquid can be seen through from the outside through the transparent tube. Then, it is possible to change the color of the bathtub at will.

Further, since the manufactured bath has a simple structure in which the transparent tube is simply welded, the number of materials for manufacturing is small, the production is easy, and the material of the transparent tube is soft. However, by reliably welding the adjacent transparent tubes to each other, it is possible to make it difficult for the mold to lose its shape.

If the transparent tube is made of a soft material, the bathtub itself can be provided with cushioning properties. For example, even if the user falls over while bathing and hits his head or body against the bathtub, bruise The shock caused by is relieved and it is possible to prevent serious injury.

[0011]

As described above, according to the bathtub manufacturing method of the present invention, a bathtub whose color can be freely changed can be easily manufactured without using a special material, and the productivity of the bathtub is improved. In addition to mass production and cost reduction, it is now possible to enjoy a variety of baths.
