Description

[Detailed description of the invention] The present invention relates to an external pot-type bathtub with a washing area that connects the bathtub body and a water heater installed outside the bathroom with a circulation pipe, and boils the water inside the bathtub body while circulating it naturally or forcedly. It is something.

Generally, in order to connect a circulation pipe to a connection hole drilled in the tank wall of the bathtub body in a bathtub with a washing area, the inner member of the circulation pipe connection fitting attached to one end (tip) of the circulation pipe is attached to the rim of the connection hole. Inside,
The outer member is disposed on the outer surface of the mouth edge of the connecting hole, and sealing materials are interposed between these two members and the inner and outer surfaces of the mouth edge of the connecting hole, respectively, and the two members are threadedly connected.

However, the sealing material interposed between the circulation pipe connection fitting and the inner and outer surfaces of the mouth edge of the connection hole deteriorates after long-term use, causing bath water to leak and land on the floor surface where the bathtub with washing area is installed. There is a risk that dripping water may corrode the metal support legs and support frames that support the bottom (back side) of the bathtub with a washing area.Also, if the bathtub is installed on the second floor, the dripping water may damage the ceiling of the lower floor. There was a risk of contamination.

The present invention was developed in view of the above conventional circumstances, and its purpose is to prevent bath water leaking due to deterioration of the sealing function of the sealing material from dripping onto the floor surface where the bathtub with washing area is installed. The dripping water (bath water) is collected by a leak catcher installed outside the tank, and the dripping water (bath water) can be led to the drain pipe connected to the drain hole of the bathtub and washing area, and drained from the bathtub and washing area. Even if drainage water such as bath water or sewage flows back to the water leak receiving side due to a blockage in the drain pipe 7, etc., this will be reliably blocked and dripping (water leakage) onto the installation floor will also be prevented. The purpose is to provide a bathtub with a washing area that can be used easily.

The basic structure of the bathtub with washing area of the present invention is to provide a water leakage catch on the outside of the lower part of the circulation pipe connection hole drilled in the tank wall of the bathtub, and to connect an auxiliary drain pipe between the water leakage catch and the drain pipe. The system is characterized in that a check valve is connected and equipped in the middle of the auxiliary drain pipe, and an example of its implementation will be explained based on the drawings.

A bathtub with a washing area is made by integrally molding the bathtub body A and the washing area B from synthetic resin material such as FRP.
This is a conventionally well-known outer pot type in which connection holes 2 are drilled at two locations on the top and bottom of one side of the tank wall a of the bathtub body A, or at one location as shown in the figure, and the other end is inserted into the connection hole 2. One end (tip) of the circulation pipe 1 connected to the pot C is connected, and a water leak catcher 3 is provided outside the lower part of the hole.

The water leak catcher 3 is for catching the melted water leaking from the connection hole 2 so that it does not drip onto the installation floor D of the bathtub with washing area, and is formed into a box shape from a synthetic resin material such as FRP.

In addition, a drain hole 4 is opened in the bottom of the water leakage catcher 3, and is located between the front drain hole 4 and the drain pipe 7 connected to the drain holes 5 and 6 of the bathtub A and washing area B. Connect the auxiliary drain pipe 8 to.

The water leak catcher 3 is attached in a protruding manner to the outer surface of the tank wall a directly below the circulation pipe connection hole 2 by means of attachment such as adhesive, and an auxiliary drain pipe 8 is installed between the drain hole 4 and the drain pipe 7. At the same time as connecting the drain pipe 8
A check valve 9 is installed in the middle of the valve.

The check valve 9 connects the drain pipe 7 from the bathtub A and the washing area B.
Drainage water such as bath water and sewage discharged into the interior may flow into the auxiliary drain pipe 8 for some reason, and the leakage catcher 3
This is to prevent the backflow of wastewater into the interior of the drain, and there are various structures, but in the embodiment of the present invention, a simple structure with a built-in valve cover 10 that closes due to the water pressure of backflowing wastewater is used. I am using it. Note that the check valve 9 may have any structure selected for use.

In the figure, reference numeral 11 indicates a circulation pipe connection fitting consisting of an inner member 12 and an outer member 13 for connecting and fixing one end of the circulation pipe 1 to the circulation pipe connection hole 2, and 14 indicates an inner fitting 12, an outer fitting 13, and the circulation pipe connection hole. A sealing material interposed between the inner and outer surfaces of the mouth rim of 2;
15 is the floor D where the bottom (back side) of the bathtub with washing area is installed.
This is a support member such as a metal support leg or a support frame that can be supported above.

In the above embodiment, the separately molded water leak catcher 3 is provided on the outer surface of the tank wall a by means of attachment such as adhesive. It may be provided and is optional.

Since the bathtub with washing area of the present invention is constructed as described above, it has the following advantages.

(1) A water leak catcher was installed on the outside of the lower part of the circulation pipe connection hole drilled in the tank wall of the bathtub body, and an auxiliary drain pipe was connected between the water leak catcher and the drain pipe.
Even if the sealing material interposed between the inner and outer edges of the connection hole deteriorates after long-term use and bath water leaks, the bath water can be caught without dripping onto the installation floor and can be drained by guiding it to the drain pipe. .

(2) A check valve is installed in the middle of the auxiliary drain pipe, so in the unlikely event that bath water or sewage drained from the drain hole of the bathtub or washing area due to clogging of the drain pipe or other reasons, will end up on the auxiliary drain pipe side. Even if water flows in, it can reliably prevent water from flowing back into the leakage receiver, and prevent water from dripping (water leakage) from the leakage receiver onto the installation floor.
There's nothing to do.

Thus, the intended purpose can be achieved.
