Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warm water bath for circulating bath water by removing water in a bath tub, purifying the water in a purification tank, sterilizing it with a sterilizing device, returning it to the bath tub again and circulating the bath water. is there.

[0002]

2. Description of the Related Art In recent years, bath water in a bathtub has been purified with a purifying material,
Hot water baths, which are returned to the bathtub and always used, have come to be used at home. A normal hot water bath has a heating means for maintaining a constant temperature, a pre-filter for removing large solids such as hair and dust, and secretions from the body in the bath water (amino acids, protein, etc. contained in body fluids). It consists of a purifying tank that removes foreign substances such as skin that has been converted into water, and a sterilizing device for bacteria in the bath water such as ultraviolet rays and ozone, so that you can take a bath at any time without changing the bath water every day. It is convenient and can save water.

[0003] The mechanism for purifying the water quality of this warm bath is considered as follows. That is, coarse dust such as hair is removed from a pre-filter made of urethane foam or the like.
(Hair-catcher), and the secretions from the body in the bath water are purified in a purification tank. In other words, the purification tank contains granular ceramics such as those obtained by crushing barley stone, natural stone, etc. and sintering them in a porous state. The bath water is purified because microorganisms eat and decompose ammonia and proteins contained in the bath water as food.
Then, bacteria derived from the body taking a bath are sterilized by a sterilizer such as ultraviolet rays and ozone. However, in recent years, in order to enable long-term use of bath water, it has been required to enhance sterilization of the bathtub wall and the inside of the piping system.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to effectively sterilize bacteria living in such bath water and further inhabiting the bathtub wall and the inside of the piping system, thereby enabling use of the bath water for a long time. It is intended to provide a warm bath.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The gist of the present invention is to provide a water intake section for taking in water in a bathtub and a pump for circulating water from the water intake section. A hot water bath equipped with a purifying tank for purifying the water, a sterilizing device for sterilizing the bacteria in the water, and a discharge unit for returning the purified and sterilized water to the bathtub. The present invention relates to a warm bath equipped with a disinfectant injection device, usually a chlorine agent injection device.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a warm water bath as described above, which is provided with an ultraviolet germicidal lamp and a separate germicide injection device, usually a chlorine agent input device, as a germicidal device. It is assumed that. In addition to the ultraviolet sterilizing lamp, a disinfectant (for example, chlorine agent) input device is added, and the disinfection of the bathtub wall and the inside of the piping system is performed by the input disinfectant. It is preferable to provide a bypass circuit before and after the purification tank.

It is particularly preferable that the disinfectant dispensing device, which is provided separately from the bath water circuit of the hot water bath, is equipped with a timer to appropriately add a required amount to the bath water. In this case, as a chlorine agent, sodium dichloroisocyanurate, trichloroisocyanuric acid, sodium hypochlorite, calcium hypochlorite are preferably used, and sodium dichloroisocyanurate is an inorganic salt or The blowing agent is mixed and used as a tablet or powder, and sodium hypochlorite is preferably used as a 1 to 14% aqueous solution. In addition, as the chlorinating agent introduction device, a device having a structure in which a trichloroisocyanuric acid tablet having low solubility is gradually dissolved while being in contact with water is excellent in handling.

[0008] By constantly irradiating the circuit with an ultraviolet germicidal lamp, the bacteria brought in by the bather can be always sterilized, and the injected germicide, for example, a chlorine agent is activated by being exposed to the ultraviolet light. As a result, the contact time with the purification bacteria in the purification tank can be shortened as much as possible. Further, it is preferable to close the bypass circuits before and after the purifying tank so that the chlorine agent does not flow into the purifying cylinder when the sterilizing agent is supplied. This is because the germicidal action of the chlorine agent sterilizes even the purified bacteria in the purification column.

[0009]

EXAMPLES Hereinafter, the warm bath of the present invention will be described in more detail with reference to examples. FIG. 1 is an overall view showing a preferred example of a warm water bath of the present invention. First, a water bath 2 and a discharge unit 3 are provided in bath water in a bathtub 1. And the hot water bath body 20
Inside are a pump 4, a purification tank 5, an ultraviolet germicidal lamp 6,
Necessary components such as a filter 7 are provided.
It is connected by. In addition, a sterilization input device, which is a separate system from the main circuit of the hot water bath, specifically, a chlorine input device 9 is disposed. In particular, a bypass 10 is provided with the purification tank 5 interposed therebetween.

[0010] Without limiting the chlorine agent dispenser 9 in particular, chlorine agent tank 9 _1, pump 9 _2, row by hypochlorite turned from chlorine agent dispenser 9 consisting timer -9 ₃ etc. to be generated It is common to be done. When sodium hypochlorite is used as the chlorine agent, there is no residue, and the chlorine concentration is less than about 2 hours.

In FIG. 1, when the chlorine agent is not charged, the bypass 10 of the purification tank 5 is operated with the tank closed, and the bath water in the bathtub 1 is taken in from the water intake unit 2,
The organic matter in the bath water is decomposed in the purification tank 5 to purify the bath water, the bacteria in the bath water are sterilized by the ultraviolet germicidal lamp 6, heated by the heater 7, and heated from the discharge port 3 to the bath tub. It will be returned in 1.

When sterilizing bacteria and the like that inhabit the bathtub wall surface and the piping system inner wall surface, a chlorinating agent is introduced into the bath water to deal with these bacteria. When the chlorinating agent is charged, the operation is performed with the bypass 10 released. In other words, when a chlorinating agent is introduced into the circuit, the chlorinating agent in the bath water may be activated by an ultraviolet germicidal lamp, and the bacteria in the bath water will be the bacteria that inhabit the wall surface of the bathtub or the inner wall of the piping system. Is to sterilize. When the bypass 10 is released, that is, when the valves at both ends of the bypass 10 are closed, the chlorine-containing agent does not enter the purification tank 5 and the internal purification bacteria do not die.

[0013]

According to the hot water bath of the present invention, not only bacteria in the bath water but also bacteria living in the bathtub wall and the inside of the piping system can be effectively sterilized. The present invention provides a safe hot water bath by long-term use.
