Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bathtub device in which welded parts are not visible from the front side.

<Prior Art> Conventionally, a bathtub device in which a top plate is provided on the top edge of the bathtub is manufactured by connecting the top edge of the side surface of the bathtub and the opening of the top plate by a method such as welding.

<Problem to be solved by the invention> However, when manufacturing a bathtub device made of stainless steel, the oxide film discolors during welding and impairs the aesthetic appearance, so the oxide film must be removed by polishing.

Furthermore, when using a colored stainless steel plate with a resin film laminated on its surface, the resin film melts or burns due to the welding heat, and the color of the welded part disappears. could not be provided.

<Means for Solving the Problems> The present invention was proposed in view of the above, and includes forming a protrusion on the side surface of the bathtub with the upper edge bent outward to form a folded shape, and The mounting allowance is made up of a horizontal piece whose lower edge is bent inward horizontally and a vertical piece whose tip edge is bent upward, and an upright piece is formed by bending the inner edge of the opening upward. The present invention relates to a bathtub device in which the above-mentioned bathtub is fitted into an opening of a top plate formed with a top plate, and the vertical piece of the attachment allowance and the upright piece are brought into contact within the protrusion and welded.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

The upper edge 2 of the side surface of a stainless steel bathtub 1 is bent outward and folded back to form a protruding part 3, and a mounting allowance 4 is formed at the lower edge of the protruding part 3.

The above-mentioned attachment allowance 4 consists of a horizontal piece 5, which is formed by horizontally bending the lower edge of the protrusion 3 inward, and a vertical piece 6, which is formed by bending the tip edge of the horizontal piece 5 upward. .

Then, the inner edge of the opening of the stainless steel top plate 7, which has an opening slightly larger than the size of the top surface of the bathtub 1, is bent upward to form the upright piece 8, and the outer edges of the three sides of the top plate 7 are bent upward. The extending piece 9 is formed by bending the edge downward, and the water return piece 10 is formed by bending the outer edge of the other side upward.

To attach the top plate 7 to the bathtub 1 described above, turn it over so that the upper edge of the bathtub 1 is on the bottom, fit the opening of the top plate 7 from the bottom of the bathtub 1 to the protrusion 3, and then Vertical piece 6 and upright piece 8 of top plate 7
The bathtub device can be manufactured easily by simply making contact with the inside of the protrusion 3 and welding the entire circumference of the tip of the vertical piece 6 and the tip of the upright piece 8.

Further, if necessary, a thick heat insulating material 11 can be pasted on the outside of the bathtub 1 and on the lower surface of the top plate 7 to improve the heat retention of the bathtub device.

Therefore, according to the present invention, the protrusion 3 and the attachment allowance 4 are formed on the upper edge of the bathtub in advance, and the upright piece 8 is formed on the top plate 7, so that the attachment allowance 4 and the attachment allowance 4 of the protrusion 3 are formed in advance. By welding the upright piece 8 of the top plate 7 inside the protrusion 3, the top plate 7 can be fixed to the upper edge of the bathtub.

<Effects of the Invention> As explained above, in the bathtub device of the present invention, the force-contacting portion is not visible from the outside, so the appearance is not spoiled.

Therefore, even if an oxide film is formed due to welding, the welded portion is not visible, and there is no need to remove the oxide film by polishing, so assembly can be facilitated.

Furthermore, even when a colored stainless steel plate with a resin film laminated on its surface is used as the material for the bathtub device of the present invention, even if the resin film is damaged during welding, it is only slight and does not reach the outside of the protrusion. It is possible to provide a bathtub device in various colors without spoiling the appearance, and it is of high practical value.
