Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub, and more particularly, to a bathtub having a circulation fitting attached to a side wall of a bathtub body.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Publication No. 57-53519
As described in the official gazette, a boiler is provided outside the bathtub, the bathtub and the boiler are connected by a circulation pipe, and the circulation pipe supplies hot water into the bathtub from the boiler and discharges water from the bathtub. Water to the boiler.

In such a connection portion between the bathtub and the circulation pipe, a circulation fitting is attached to a side wall of the bathtub body, and a supply port and a discharge port provided at a portion of the circulation fitting protruding outward from the side wall of the bathtub body. By connecting circulation pipes from the boiler to the outlets, hot water is supplied from the boiler into the bathtub, and water is discharged from the bathtub and sent to the boiler.

By the way, for example, Japanese Utility Model Laid-Open Publication No.
As described in the official gazette, when a bathroom is provided on the upper floor, if the water leaks from the connection between the bathtub and the circulation pipe, the lower floor will be damaged. Placed on bread.

[0005]

However, when the bathtub is placed on the waterproof pan, the circulating pipe has to penetrate the waterproof pan, which requires a lot of work. In addition, when sewage accumulates in the waterproof pan, there is also a problem that dirt adheres and emits an odor.

Accordingly, the present invention has been made in view of the above-mentioned problems, and the object thereof is to:
It is possible to solve the problem in the conventional bathtub and to provide a bathtub that does not leak water from a connection portion between the bathtub and the circulation pipe.

[0007]

In order to achieve the above object, a bathtub of the present invention has a circulation fitting attached to a side wall of a bathtub body, a supply flow passage and a discharge flow passage provided in the circulation fitting, and a circulation bath. A supply port and a discharge port are respectively provided in a portion of the metal fitting facing the inside of the side wall of the bathtub body and a portion facing the outside of the side wall of the bathtub body. Each supply port is communicated with a supply flow path, and each discharge port is provided with a discharge flow. In the bathtub that is communicated with the road, a tubular body that covers the circulation fitting is protrudingly provided on the outer surface of the side wall of the bathtub body, and a closing lid is attached to the distal end opening of the tubular body. Is characterized by having a supply port and a discharge port.

[0008] In the present invention, the material of the bathtub body may be any of those conventionally used as the material of the bathtub body, and is not particularly limited. Examples thereof include FRP, stainless steel, wood, and artificial. Marble, cast iron, etc. can be used.

[Operation] In the bathtub of the present invention, a tubular body covering the circulation fitting is protruded from the outer surface of the side wall of the bathtub body, and a closing lid is attached to the opening at the tip end of the tubular body. Alternatively, since the supply port and the discharge port are provided in the closing lid, even if water leaks from the junction between the side wall of the bathtub body and the circulation fitting, the water leak is received by the cylindrical body, so that the water leaks downward. There is no fear.
