Abstract

PURPOSE:To prevent a packing from being easily dropped off from the upper end part of the vertical wall of a waterproof pan by adhering the leg piece of the packing to the inner surface part of the vertical wall of the waterproof pan, providing a water tight material on the upper surface of the packing, and bringing the upper end part of the watertight material into contact with the lower surface of the upper surface part of a bathtub. CONSTITUTION:A packing 3 is provided between the vertical wall 122 of a waterproof pan 1 and the upper surface part 21 of a bathtub 2, one side wall of the packing is extended along the inner surface of the vertical wall 122 of the waterproof pan 1 to form a leg piece 33. The inner surface of a recessed groove 31 on the lower surface of the packing 3 and the inner surface part of the leg piece 33 are adhered to the vertical wall 122 by an adhesive 4. A watertight material 5 consisting of a soft vinyl chloride resin foamed body is inserted into a recessed groove 32 on the upper surface of the packing 3, and the upper end part of the watertight material 5 is brought into contact with the lower surface of the upper surface part 21 of the bathtub 2. Consequently, the packing 3 is firmly mounted on the vertical wall 122, and never easily removed when the bathtub 2 is inserted into a fitting hole 12, and watertightness can be held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub with a washroom including a waterproof pan having a washroom floor and a bathtub fitting hole, and a bathtub fitted into the bathtub fitting hole of the waterproof pan.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Publication 57-43250.
As disclosed in JP-B No. 57-81697 and the like, with a washing pan comprising a waterproof pan having a washing floor and a bathtub fitting hole, and a bathtub fitted into the bathing fitting hole of the waterproof pan The bathtub is known.

By the way, in such a bathtub with a washbasin, the upper end of the bathtub has an upper surface extending outward and an edge of the upper surface is bent downward to form a folded edge so that a waterproof pan is formed. A receiving portion is formed around the bathtub fitting hole by a bottom wall and a rising wall that rises upward from the bottom wall, and the folded edge of the bathtub is inserted on the receiving portion, so that the rising wall of the waterproof pan is A packing is provided between the upper end and the lower surface of the upper surface of the bath.

[0004]

However, in such a bathtub with a washing place, when the bathtub is fitted in the bathtub fitting hole of the waterproof pan, the packing attached to the upper end of the rising wall of the waterproof pan is used for the bathtub. It has a drawback that it comes into contact with the outer surface of the side wall and falls into the bathtub fitting hole. When the heat insulating material is wound around the outer surface of the side wall of the bathtub to save energy, the heat insulating material often comes into contact with the packing when the bathtub is fitted, and thus the packing comes off more significantly.

The present invention has been made in view of the above problems in a conventional bathtub with a washing room, and an object of the present invention is to solve the above problems and to provide a packing with a rising wall of a waterproof pan. It is to provide a bathtub with a washroom that does not easily fall off the top edge of the.
