Abstract

PROBLEM TO BE SOLVED: To obtain washing water which is friendly to the environment and can be preserved for a long period by providing the washing water which is electrolytically ionized water having a pH of a specific value or above and a high concentration of hydrogen ions and removing the impurities, such as dissolved salts, included in the washing water to prevent the easy discharge of the electrons in the washing water into the air. SOLUTION: The electrolyzed water for washing is obtained by mixing the hydroxyl ionized water 40 produced by a hydroxyl ionized water production apparatus 4 with the alkali ionized water 30 of the pH 12.5 produced by an alkali ionized water production apparatus A consisting of an electrolytic device 1, a reverse osmosis membrane device 2 and an electrolytic device 3. The hydroxyl ionized water 40 is added to the water described above in a range of 0 to 50 wt.%. The electrolyzed water for washing has the pH value of >=12 and is removed of the impurities such as dissolved salts, included in the electrolyzed water so that the easy discharge of the electrons in the electrolyzed water is averted. Therefore, if the electrolyzed water is put into a container or tank of a hermetic state, the electrolyzed water may be preserved for a long period (about 2 to 3 years) in the state of maintaining efficacy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an air conditioner (including a car air conditioner), a bathtub, a kitchen sink, an outer wall of a building,
The present invention relates to cleaning water suitable for cleaning an object to be cleaned such as an automobile or a signboard.

[0002]

2. Description of the Related Art Detergents have conventionally been used for cleaning air conditioners, bathtubs, kitchen sinks, building exterior walls, automobiles, signboards and the like.

[0003]

When a detergent is used, a large amount of rinsing water is required to wash off the alkaline salts and surfactants remaining on the surface of the object to be cleaned after the cleaning. In addition, since the wastewater contains a detergent component, it contaminates rivers and the like, and causes workers to have rough skin. In addition, although alkaline ionized water is known to have a cleaning action, it takes time to produce water and returns to the original water in a few hours. Was unsuitable.

An object of the present invention is to provide washing water which is environmentally friendly and can be stored for a long time.

[0005]

Means for Solving the Problems [Claim 1] Wash water is electrolytic ion water having a pH value of 12 or more and having a high hydrogen ion concentration, and is used to remove impurities such as dissolved salts contained in the wash water. In addition, electrons in the washing water are not easily discharged into the air.

When the washing water comes into contact with the dirt on the object to be cleaned, a large number of negative ions seeking positive ions turn the dirt into positive ions. The surface of the positively ionized dirt attracts negative ions and wraps the dirt, and the surface of the object to be cleaned is also covered with negative ions, and the dirt is repelled by the negative ions of the dirt and the negative ions on the surface of the object to be cleaned. Pull away from. Since the dirt is completely lifted from the surface of the object to be cleaned in detail, it can be easily removed from the object to be cleaned.

[Claim 2] The washing water contains hydroxyl ions (H ₃ O ₂ ⁻ ). As for the hydroxyl ion (H ₃ O ₂ ⁻ ), the H—O—H portion shows hydrophilicity and the remaining H—O portion shows hydrophobicity. For this reason, the washing water to which hydroxyl ions (H ₃ O ₂ ⁻ ) are added has an additional surface activating effect, and is excellent in washing ability.

[Claim 3] The washing water is suitable for washing air conditioners (including car air conditioners), bathtubs, kitchen sinks, building exterior walls, automobiles, or signboards.
