BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub apparatus, and more particularly to a bathtub hot water purification apparatus for sucking hot water in a bathtub, performing cleaning treatment such as filtration, sterilization and heat retention, and then ejecting the hot water again into the bathtub. It is a thing.

[0002]

2. Description of the Related Art Recently, hot water in a bathtub is sucked up by a circulation pump, dirt is filtered by a filtration tank, heated by a heater and kept at a preset temperature, and further sterilized by ozone to keep the hot water constantly clean and at an appropriate temperature. A bath water purifying device, which is a so-called 24-hour bath device, capable of taking a bath 24 hours a day has been developed and widely used.

An example of the hot water purifying device for the bathtub is as shown in FIG. 6, and 4 is a main body for accommodating the cleaning treatment equipment as a unit. A filtration tank 5 for filtering, a circulation pump 6 for forcedly circulating hot water, and a heater 7 for keeping the hot water at a set temperature are connected in series by a connecting pipe and housed, and as an ozone generator for sterilizing the hot water with ozone. The ozonizer 8 is stored.

A prefilter 1 for removing large dirt in the hot water sucked into the apparatus body 4 in advance at the hot water inlet of the bathtub 1.
No. 0 is attached, a jet nozzle 11 for ejecting the purified hot water as a jet flow to the bathtub 1 is attached to the spout, and the apparatus body 4 is a pre-filter 10 in which the hot water pipe 3 is attached to the hot water spout. , And the spout tube 9 is connected to the jet nozzle 11 attached to the spout opening to attach it to the bath 1.

Further, an intake pipe 12 is connected to the negative pressure portion of the jet nozzle 11, and a solenoid valve 13 for opening and closing the pipe line is attached to the tip of the intake pipe 12, and inhaled air is made into ozone. In order to do so, the ozonizer 8 is attached.

In the above apparatus, the hot water 2 in the bathtub 1 is sucked by the hot water pipe 3 into the apparatus main body 4 while the dirt is removed by the pre-filter 10 by the operation of the circulation pump 6, and enters the apparatus main body 4 first, and then in the filtration tank 5. After being filtered and subsequently kept warm by the heater 7, it is jetted again into the bath 1 from the jet nozzle 11 at the tip of the spout tube 9.

At this time, when the solenoid valve 13 is open, the air sucked from the intake pipe 12 is mixed with the hot water, and a jet jet containing air is jetted from the jet nozzle 11 to the bath tub 1 to form a bubble bath and the ozonizer 8 Is activated, the ozonized air is jetted into the tub 1 to sterilize the hot water 2 with ozone.

Conventionally, as shown in FIG. 7, the main body 4 of the apparatus is placed on the floor and installed in the bathroom, and the above-mentioned pre-filter 10 and jet nozzle 11 are integrated into the suction unit 1.
4 or as a separate hot water and hot water unit attached to the side surface of the bathtub 1 by using a suction cup or the like, and connecting the hot water pipe 3 and the hot water pipe 9 to the prefilter 10 and the jet nozzle 11 respectively. Most of the devices are simple installation types that connect the bathtub 1 and the device body 4.

Since the simple installation type device does not need to make holes for attaching the prefilter 10 and the jet nozzle 11 to the bathtub 1, the installation of the device was very easy.
Since the hot water and hot water units are attached to the side surfaces, the hot water pipe 3 and the hot water pipe 9 are piped in a state of being visible in the bathtub 1, which is unsightly and at the same time the bathtub becomes narrow.

Further, if the apparatus body 4 is placed on the floor, the floor becomes narrower. Therefore, the apparatus body 4 may be made small and placed on the edge of the bathtub 1, or placed on the bay window of the bathroom or mounted on a wall. However, if the apparatus main body 4 is downsized, the cleaning ability is inevitably lowered.

For this reason, recently, many outdoor installation apparatuses have been installed in which the apparatus body 4 is placed outdoors and the bathtub 1 is connected to the apparatus body 4 by piping through the wall of the bathroom. In addition, even those placed indoors have been developed and sold that have pipes that pass through the wall from the back of the bathtub and lead to the main body of the device to improve the appearance of the pipes.

In this case, as shown in FIG. 5, a bath hole 1 and a spout hole 16 are provided on the side surface of the bathtub 1.
5 and spout hole 16 with pre-filter 10 and jet nozzle 1
Units 1 and 1 are embedded and installed, and the hot water pipe 3 and the hot water pipe 9 that pass through the wall of the bathroom are connected to the hot water pipe connecting port 17 and the hot water pipe connecting port 18 projecting outside of the bath 1.

In this way, the inside of the bathtub 1 is not narrowed because the hot water pipe 3 and the hot water pipe 9 are not piped and the prefilter 10 and the jet nozzle 11 are not protruding. Since the hot water pipe 3 and the hot water pipe 9 are hidden behind the bathtub 1 and cannot be seen, it is not unsightly.
Further, even if the bathroom is small, it is possible to install the apparatus body 4 which is large and has a high cleaning ability.

[0014]

However, in order to install a device such as an external type, the bathtub 1 must be provided with two holes, a suction hole 15 and a spout hole 16, on the side surface. Besides this, of course, there are drainage holes on the bottom surface for draining hot water, so a total of three holes must be drilled.

In order to reduce the number of holes made in the bath 1, a pre-filter 10 and a jet nozzle 11 are opened on the side.
It is also possible to install it in one hole.

However, the pre-filter 10 is desired to be installed at the lowest position on the side surface so that the dirt sunk on the bottom can be sucked in, and the jet nozzle 11 is desired to be installed on the highest position on the side surface so that the jet flow hits the bather well.

For this reason, if the pre-filter 10 and the jet nozzle 11 are attached to one hole formed on the side surface, the suction of dirt becomes worse, or the jet flow of the jet does not hit the bather well. .

The present invention eliminates the above-mentioned drawbacks of the prior art, and only needs to make two holes in the bathtub for drainage, and the prefilter 10 and the jet nozzle 11 can fully function. The purpose is to be able to attach it to the position where it can be exerted.

[0019]

That is, according to the present invention, hot water in a bathtub is sucked by a hot water pipe, a circulation pump, a filtration tank,
