Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying method for diffusing humidifying water into the air to humidify the air, and a humidifying apparatus used therefor.

[0002]

2. Description of the Related Art Conventionally, general tap water has been used as humidifying water that is diffused into the air for the purpose of humidifying the air.

[0003]

However, in general, the p
The H value is adjusted with a neutral value as a target, but the humidifying water is completely vaporized during the emission process and before it is absorbed into the air. When it remains floating in the air in the mist state, it tends to absorb acid components (carbon dioxide gas, etc.) in the air and acidify due to contact with the air. Especially, in urban areas where air pollution is increasing, it is included in the air. This acidification tendency is strong due to the influence of pollutants such as sulfides that are generated, and due to this acidification, there is a problem that promotes corrosion of metal members in the air conditioning equipment including the humidifier itself and the air-conditioned room. This acidification is not preferable in terms of safety and hygiene and comfort of personnel in a humid atmosphere.

An object of the present invention is to prevent corrosion due to acidification of humidifying water and to improve safety and comfort for personnel in a humid atmosphere.

[0005]

The humidifying method according to the present invention is characterized in that the pH value of the humidifying water is adjusted to the increasing side, and the adjusted humidifying water is diffused into the air to humidify the air. It is in.

A first characteristic configuration of the humidifying device according to the present invention is to adjust the pH value of the humidifying water supplied from the water supply source to the dispersing means to the increasing side, for spreading the humidifying water into the air.

The control means is provided to control the adjusting means so that the pH value of the humidifying water supplied to the dissipating means becomes the target alkaline value based on the detection information of the detecting means.

[0008]

That is, in the humidifying method of the present invention, since the pH value of the humidifying water is adjusted to the increasing side and the humidifying water is diffused into the air, the acidic component in the air is absorbed by the contact with the air. However, acidification can be suppressed as compared with the conventional humidification in which the increase in pH value is not adjusted.

In the first characteristic configuration of the humidifying device of the present invention, the pH value of the humidifying water supplied from the water supply source is adjusted to the increasing side by the adjusting means, and the adjusted humidifying water is aired by the dissipating means. Disperses into and humidifies the air.

That is, the humidifying method of the present invention is implemented in the first characteristic configuration.

In the second characteristic configuration of the humidifying device of the present invention, when the pH value of the humidifying water is adjusted to the increasing side by the adjusting means, the adjusting means is controlled by the control means based on the detection of the pH value to disperse The pH value of the humidifying water supplied to the means, that is, the pH value of the humidifying water diffused into the air is automatically adjusted and maintained at a target alkaline value.

[0012]

In other words, according to the humidifying method of the present invention, acidification of the release humidifying water due to acidic components in the air can be suppressed, so that corrosion of the metal member in the air conditioning equipment including the humidifying device itself or in the room to be air conditioned. Can be effectively prevented, and in addition, safety and comfort for personnel in a humid atmosphere can be improved.

According to the first characteristic construction of the humidifying device of the present invention, the humidifying device suitable for carrying out the humidifying method of the present invention can be provided in that the adjusting means can adjust the pH value increase of the humidifying water. .

According to the second characteristic construction of the humidifying device of the present invention, the effects of the above humidifying method of the present invention are stable while the device management is easy without the need for artificial pH value monitoring and pH value adjusting operation. The humidifying device can be obtained.
