The flow of hot water is reminiscent of a hot spring bath, further increasing the feeling of satisfaction. In the reflux from Ob, by configuring a bubble generating means here, it is possible to further enhance the feeling of satisfaction during bathing.

If the temperature of the water in the bathtub body 2 drops during bathing in the second step, the reheating section 7 can be operated to raise the temperature as necessary during reflux to perform hot heating. can. In addition, foreign matter such as dirt and hair that enters the bathtub body 2 when taking a bath is light and easily floats upwards.
The hot water is introduced into the hot water storage means 5, purified in the purified water m6 during reflux, and then refluxed into the bathtub body 2 in two series, so that the hot water in the bathtub body 2 can be maintained in a clear state.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a system explanatory diagram of the overall configuration of the present invention, and in this figure, reference numeral 1 is a bathtub with a washing area, and this bathtub 1 integrally constitutes a bathtub body 2 and a washing area 3. A hot water storage means 5 is connected to the drain 4 of the washing area 3, and the hot water storage means 5 passes through a water purification section 6 and a reheating section 7 to a pump 8 to bring the bathtub into the bathtub.
A reflux path 9 for refluxing the main body 2 is provided, and the reflux path 9
At the downstream end of the bath, a hot water outlet for reflux 10a and 10b is provided to constitute a bath device.

The floor surface of the washing area 3 is appropriately sloped toward the direction of the drain port 4. Further, a gutter-like portion may be provided near the drain port 4 along the bottom of the bathtub body 2.

Although the hot water storage means 5 is configured as a tank installed below the drain port 4 in the illustrated example, it can also be configured as a tank installed separately from the bathtub 1. In this case, the hot water storage means 5 Piping may be provided between the port 4 and the hot water storage means 5. Further, hot water outlet portions 10a, 101:+ for reflux are provided at the upper part and side wall portion of the bathtub body 2. A bubble mixing and spouting nozzle utilizing an ejector action can be configured in the reflux hot water outflow 5iob of the side wall. As mentioned above, the reflux route 9 includes a water purification section 6 and a reheating section 7. The water purification section 6 has a filtering function and a sterilization function, and the reheating section 7 is located downstream of the pump 8. A heat exchanger 11 and a burner 12 for heating the heat exchanger 11 are provided on the side. The reflux route 9 has a branched backwash route 13 for the filtration function of the water purification section 6, and this backwash route 13 has switching valves 14a, 14 on the upstream and downstream sides of the water purification 11!6. b, and a drainage path 16 is connected to the selection port 15a of the upstream switching valve 14a, and a backwash water path 18 leading to the backwash water source 17 is connected to the selection port 15b of the downstream switching valve 14b. There is.

In the above configuration, when a person enters the bathtub body 2 and the hot water inside overflows from the upper part into the washing area 3, the overflowing vortex is introduced into the tank serving as the hot water storage means 5 through the drain port 4. Next, the hot water in this hot water storage means 5 flows through the reflux path 9 by the pump 8, and is passed through the water purification section 6 and the reheating section 7 in sequence, and then passes through the reflux hot water outlet section 10b provided on the side wall of the bathtub body 2 or on the upper part. Returning hot water flowing out @ I Oa back into the bathtub body i can be easily controlled by providing an overflow detection means (not shown) in the hot water storage means 5, etc. . For example, by introducing hot water into the hot water storage means 5 and detecting it by the detection means, it is possible to detect a crossflow of overflowing water, that is, a person entering the bathtub body, and based on this detection, a predetermined Reflux control can be performed automatically. Further, such reflux control can be performed by using a sensor that detects the lid of the bathtub body 2,
That is, when this sensor detects the lid, it is possible to prevent reflux from occurring.

If the temperature of the water in the bathtub body drops during the above bathing, additional heating can be performed by operating the burner 12 and raising the temperature by the heat exchanger 11 as necessary during reflux. Foreign matter such as dirt and hair that gets into the bathtub body 2 when taking a bath is light and therefore tends to float upwards. Therefore, as water overflows from the upper part of the bathtub body 2, it is introduced into the hot water storage means 5 through the drain port 4, and then this hot water storage means 5 flows through the reflux path 9 together with the part that refluxes from inside. Thus, these foreign substances are purified in the water purification section 6 and removed from the hot water flowing back into the bathtub body 2, and sterilization can be performed in the water purification section 6 if necessary.

In this way, the hot water in the bathtub body 2 can be maintained in a clear state. Foreign matter accumulated in the water purification section 6 may be removed from the water purification section 6 by replacing the filter material of the water purification section 6 at appropriate intervals, or as described above, the foreign matter accumulated in the water purification section 6 may be removed from the water purification section 6 in the reflux path 9.
The backwashing path 13 can be configured to have a branched configuration, and the water can be removed from the water purification unit 6 by backwashing after being used for an appropriate period of time.

In the above-mentioned backwash path 13, when the reflux is not performed, the backwash water from the backwash water path is passed through the switching valves t4a and 14b to the water purification section 6 in the opposite direction to the reflux. and the switching valve 14a.

By draining the water from the drainage path 16 via the water pipe 14b, foreign matter is removed by backwashing and the filter medium is regenerated. In addition to tap water, hot water in the bathtub body 2 is used as backwash water. I can do both.

Note that the hot water lost from the reflux system due to the initial supply of hot water into the bathtub body 2 or the use of hot water may be replenished as appropriate using the hot water supply device 19 or the like.

(Effects of the Invention) As described above, the present invention provides a bath device using a bathtub with a washing area, in which hot water overflows from the top of the bathtub body during bathing, and the overflowing hot water is routed through the drainage outlet of the washing area. Since the structure is such that the overflowing hot water is not wasted, the water level in the bathtub body can be maintained at a high level that prevents it from overflowing, without having to pay special attention to the water. When a person enters the bathtub, the water overflows, making the bath very satisfying.In addition, the water level in the bathtub is not affected by body size, so the water level may drop after a large person takes a bath. This has the effect of causing no inconvenience. The hot water can be returned to the bathtub by selecting either the reflux hot water outlet provided on the top or the side wall, or through both at the same time. In the reflux of
The flow of the refluxed hot water can make the bath at the hot spring resort exciting, further increasing the feeling of satisfaction, and the reflux from the refluxing hot water outlet provided on the side wall can constitute a bubble generating means here. This has the effect of further increasing the feeling of satisfaction when taking a bath.
