Abstract

PURPOSE:To simply take a bath in a carbonated hot spring by separating combustion exhaust gas of a hot water supply machine by a carbonic acid gas separator and dissolving it once in a dissolver, and pouring this dissolved water into a bathtub. CONSTITUTION:Combustion exhaust gas E of a gas hot water supply machine 1 is sucked by a pump 5 and fed to a carbonic acid gas separator 4. In the separator 4, carbonic acid gas separated from, for instance, combustion exhaust gas E of 10-15% carbonic acid gas concentration and concentrated to 70-80%, is fed to a dissolver 6 through a check valve 5 and only that which is dissolved in feed water W is supplied to a bathtub 2 as dissolved water C of carbonic acid gas. In such a way, bathing by an artificial carbonated hot spring can be enjoyed easily without executing a preparation work such as purchasing an artificial carbonic acid gas solvent, and throwing it into a bathtub, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an artificial carbonated spring device for bathrooms that allows bathing with carbonated springs easily in a home bathroom.

Conventional technology Natural simple carbonated springs (hereinafter referred to as carbonated springs) are hot springs with a capacity of 1 kg.
It contains free carbonic acid of 1,000 μm or more, and the solid component content is 1,000 mg or less.

When you bathe in this carbonated spring, the skin capillaries on the surface of your skin dilate, so you feel a pleasant warm sensation even when the water is at a low temperature. Bathing in carbonated springs is used to treat heart valve disease, nervous breakdown, hysteria, etc. In addition, drinking carbonated springs not only promotes the secretion of gastric juices, but also promotes physiological movement of the gastrointestinal tract, promotes bowel movements, and aids in digestion.
It is effective for patients with chronic gastric catarrh, hypoacidemia, or chronic constipation. It is also widely used as a cooling agent and as a mineral mineral spring for meals.

Sodium bicarbonate, sodium carbonate,
There is a method of adding tablets of artificial carbon dioxide bath salts, which are made mainly of succinic acid with stabilizers added, into the bath water.

When a 50-gram tablet of this artificial carbon dioxide bath agent is placed in a general household bathtub (water volume: 1502.38°C), the carbon dioxide concentration is approximately 145 ppm. When bathing in this artificial carbonated spring, physiological effects such as an increase in blood flow and a heat-retaining effect have been observed, and experimental results with other animals have shown that it increases tissue oxygen partial pressure, increases local tissue flow rate, promotes the removal of lactic acid from the blood,
It is recognized that it has anti-inflammatory effects. From these physiological effects, sensitivity to cold, recovery from fatigue, hemorrhoids,
It has been shown to have clinical effects on diseases such as bedsores, peripheral artery occlusive disease, and hypertension.

Problems to be Solved by the Invention However, in order to take a bath in an artificial carbonated spring using artificial carbon dioxide gas bath additives, it is necessary to go to the trouble of purchasing artificial carbon dioxide gas bath additives, and to put in an amount commensurate with the volume of the bathtub. There was a difficult problem to solve.

An object of the present invention is to easily realize bathing in an artificial carbonated spring at home without having to perform troublesome preparatory work such as preparing and adding artificial carbon dioxide gas bath additives.

Means for Solving the Problems In order to achieve the above object, the present invention separates the combustion exhaust gas of the water heater that supplies hot water to the bathtub using a carbon dioxide gas separator, and once dissolves the carbon dioxide gas obtained in a dissolution tank, It is like pouring water into a bathtub.

Effect: With the above-described configuration, the water in the bathtub automatically becomes artificial carbonated spring water without any human intervention.

Example An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a configuration diagram of an apparatus according to the present invention that uses carbon dioxide gas separated from combustion exhaust gas to produce an artificial carbonated spring when a gas water heater is used to supply hot water to a bathtub. In the figure, in the gas hot water supply 1la1, the heat obtained by burning the fuel gas G is exchanged with the water supply W to create a bath! Hot water is being supplied H to 2. The combustion exhaust gas E at this time is sucked by the pump 3 and sent to the carbon dioxide separator 4. The carbon dioxide separator 4 is equipped with a PSA (Pressure) using an adsorbent such as molecular sieve or activated carbon.
Swing Adsorption) recovery equipment and carbon dioxide separation and concentrators using gas separation membranes are used. The carbon dioxide gas, which is separated from the combustion exhaust gas E with a carbon dioxide concentration of 10 to 15% and concentrated to 70 to 80%, is passed through the check valve 5.
It is sent to the dissolution tank 6 via. Only the concentrated carbon dioxide dissolved in the water supply W in the dissolution tank 6 is supplied to the bathtub 2 as carbon dioxide dissolved water C. This means that excess carbon dioxide gas will not enter the bathroom.

The carbon dioxide dissolved water C is mixed with hot water supply water to form an artificial carbonated spring.

The concentration of carbon dioxide gas dissolved in this artificial carbonated spring, ie, bathtub, is about 300 ppm, as shown in the diagram below.

Figure 2 shows another embodiment of the present invention, in which carbon dioxide gas separated from combustion exhaust gas is directly injected into the hot water supply H when a gas water heater is used to supply hot water in the bathroom. It is a block diagram of the apparatus used as carbonated spring.

Concentrated carbon dioxide gas obtained by the same configuration as explained in FIG. do.

In this case, the hot water supplied to the bathtub 2 can be pre-warmed and the temperature adjusted using a water heater, and the artificial carbonated spring can be enjoyed by directly applying it to the body, such as in a shower or with hot water.

As described in detail, the artificial carbonated spring device for bathrooms of the present invention provides the following various effects.

(1) Since the combustion exhaust gas from the water heater, which was conventionally released into the atmosphere, is used, it is possible to take a bath in an artificial carbonated spring without any consumables.

(2) You can easily enjoy bathing in artificial carbonated springs without having to purchase artificial carbonated gas bath additives or perform troublesome preparation work such as adding them to the bathtub.

(3) Only the carbon dioxide dissolved in the water in the dissolution tank is supplied to the bathtub as dissolved water, and excess carbon dioxide does not enter the bathroom, so unsafe conditions such as oxygen deficiency do not occur. .
