Description

[Technical Field]

[0001] This invention relates to a bath with a bathtub, such as a rock bath, tile bath, stainless steel bath, glass bath, high bar bath, or unit bath in a pool, open-air hot spring, indoor hot spring, or ordinary household bath, that allows the remaining water in the bathtub and the sedimented wastewater in the bathtub to be drained individually or separately, keeping the water in the bathtub always clean and allowing it to be reused, thereby realizing water conservation, and a bath with a drainage and gas blowing cassette that supplies air, oxygen gas, hydrogen gas, etc. into the bath to create a bubble bath, providing warming, cleansing, healing, heat retention, massaging, and other effects on the body while bathing. [Background technology]

[0002] In the case of ordinary household baths, after use, the hot water in the bathtub floats to the surface and the heavier dirt settles to the bottom, so all of the water is drained after cleaning the bathtub. In addition, some of the water is used for rough washing of laundry before cleaning the bathtub. On the other hand, in a free-flowing hot spring bath, dirt floating on the surface of the water is automatically discharged outside the bath by overflowing, but it settles and accumulates at the bottom, so it is drained without being reused before it cools down, which is a waste in terms of saving water, especially in hot springs. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0003] To provide a bathtub equipped with drainage and gas blowing cassettes, which allows the remaining water in the bathtub and the sedimented wastewater in the bathtub to be drained individually or separately, keeps the water in the bathtub always clean, and simultaneously saves water, and further supplies air, oxygen gas, hydrogen gas, etc. during bathing to provide a bubble bath, thereby providing effects such as a warm bath effect, a cleansing effect, a healing effect, a warming effect, and a massage effect on the body. [Means for solving the problem]

[0004] The main technical configuration of the bath in this invention that satisfies the above-mentioned problems is as described below in (1). (1) A bathtub (100) with a bathtub (101), in which a drainage / gas blowing cassette (200) is detachably installed on the bottom of the bathtub, the drainage / gas blowing cassette (200) is formed of a drainage / gas supply pipe (203) with a large number of holes (201, 202) arranged thereon, the drainage / gas supply pipe (203) is connected to a drainage / gas supply main pipe (204) extending inside and outside the bathtub, the drainage / gas supply main pipe (204) is connected to a drainage main pipe (301) and a gas supply main pipe (302) via a three-way valve (300), and the three-way valve (300) is provided to switch the communication connection between the drainage main pipe (301) and the gas supply main pipe (302) and the drainage / gas supply main pipe (204). [Effects of the Invention]

[0005] The bathtub equipped with the drain and gas supply cassette of this invention exhibits extremely significant effects thanks to the configuration described above (1). Specifically, it maintains the water in the bathtub clean while simultaneously conserving water. Furthermore, air, oxygen gas, hydrogen gas, etc. are supplied during the bath to create a bubble bath, which benefits the body through microbubbles and the ultrasound and high heat generated when the microbubbles collapse. The synergistic effects of these two components—microbubbles, ultrasound, and high heat—provide a warm bathing effect, rubbing the skin, promoting peripheral blood circulation, and increasing blood flow. Cleansing effects include body bathing, cleansing the inside of the drain pipe, removing sebum clogged in pores, removing clogged sweat glands, reducing body odor, and removing dirt with negative ions. As for soothing effects, the film of bubbles covering the body reduces water pressure during bathing, and the bursting of the bubbles stimulates the parasympathetic nervous system, creating a relaxing effect and reducing amylase levels. The heat retention effect increases the skin temperature slightly compared to plain water, making it less likely for the body to get cold after bathing. The massage effect is also comfortable for the elderly and infants. These effects are further enhanced by the bubbling effect when hydrogen gas is supplied. [Brief explanation of the drawings]

[0006] [Figure 1]FIG. 3 is a cross-sectional view taken along the arrow AA in FIG. 2, showing an embodiment of the present invention. [Figure 2] FIG. 2 is an explanatory plan view of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0007] The mode for carrying out the present invention will be described in detail with reference to the embodiment shown in FIGS. A bathtub 100 with a bathtub 101 is connected to a main drain pipe 102. The main drain pipe 102 is connected to a low point such as the center or corner of the bathtub bottom. In this example, the piping layout indicates that it is connected to a low point on the right side of the screen in Figure 2. A cover valve (drain valve) 103 is provided at this connection so that it can be opened and closed vertically. The cover valve 103 is opened and closed by a device that operates the cover valve 103 up and down via a link mechanism 105 from a solenoid drive unit 104 at the bend in the main drain pipe 102, opening and closing the connecting part.

[0008] Meanwhile, a drainage / gas blowing cassette 200, combining a rectangular shape and an X-shape, is detachably placed on the bottom of the bathtub 101. The X-shape may be omitted. The drainage / gas blowing cassette 200 is formed by a drainage / gas supply pipe 203 with a number of round holes 201 penetrating vertically and an array of rectangular slit holes 202. A drainage / gas supply main pipe 204 extending inside and outside the bathtub is connected to the drainage / gas supply pipe 203 of the drainage / gas blowing cassette 200, and a drainage main pipe 301 and a gas supply main pipe 302 are connected to the drainage / gas supply main pipe 204 via a three-way valve 300. The three-way valve 300 is provided so that the drainage / gas supply main pipe 203 can be switched between communication with the drainage main pipe 301 and the gas supply main pipe 302. The drainage main pipe 301 is connected to a drainage pump 304 via a solenoid-operated supply valve 303. The gas supply main pipe 302 is connected to a gas supply pump 306 via a supply valve 305 of an electromagnetic valve type.

[0009] With these configurations, the bath 100 can be configured such that, during bathing, the three-way valve 300 is switched to the gas supply main pipe 302 side, and air and / or hydrogen gas is supplied into the bath through the numerous round holes 201 and rectangular slit holes 202 in the drainage / gas supply pipe 203, turning it into a vibrating bath and providing the many aforementioned benefits to the body. After each bather, before the next bather arrives, three-way valve 300 is temporarily switched to the drain main pipe 301 side and drain pump 304 is operated to suck up only the wastewater that has accumulated mainly at the bottom of the bathtub through round hole 201 and rectangular slit hole 202 in drain / gas supply pipe 203 and discharge it outside the bathtub through drain main pipe 301. This process is repeated using appropriate control means, keeping the water in the bathtub always clean and allowing for bubbling bathing, or bubble bathing, while achieving the above-mentioned excellent effects, making it possible to reuse bath water and advantageously reuse any remaining water for laundry, etc. Therefore, it goes without saying that the bath 100 of this invention has tremendous effects in terms of energy and water saving, as well as the health maintenance effects mentioned above. [Industrial Applicability]

[0010] This device exhibits the excellent effects described in the "Effects of the Device" above, and by advantageously enabling the effective use of the various baths mentioned above, it will make a great contribution to the development and energy conservation of the bathing industry.
