Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water absorbent humidifier for a ventilation type humidifier installed in a circulating air passage of an air conditioner or the like.

[0002]

2. Description of the Related Art Ventilation-type humidifiers perform humidification by allowing an air stream to pass through a uniformly absorbent water-absorbing humidifier, and more specifically, they are contained in the humidifier by the sensible heat of circulating air. It vaporizes and evaporates water.

The ventilation type humidifier has been in practical use for about 10 years, but has started to spread due to the following advantages. Energy saving and low running cost. Approximately 70% of the amount of humidified water absorbed becomes the effective amount of moisture (vaporized), resulting in high efficiency. There is no splash of water. The device is simple and does not take up much space. It has a cooling effect because it takes away the latent heat of vaporization and vaporizes.

On the other hand, the disadvantages are as follows. Bacteria propagate on the humidifying material, which disperses in the air current. The scale that adheres to and accumulates on the humidifying material becomes white powder and scatters, adversely affecting OA equipment in the room. Due to the scale that adheres to and deposits on the humidifying material, the moisture content of the humidifying material decreases significantly within a short period of time, making it unusable as a humidifying material.

[0005]

The reason why bacteria and the like propagate on the humidifying material is that, for example, a humidifier installed at a workplace is used on weekends.
This is because, if the humidifying material is left unused for a day, the humidifying material will provide an environment suitable for the growth of bacteria under a warm room temperature where it absorbs water. Then, when the humidifier is reused, bacteria and the like propagated in the humidifying material are dissipated indoors by riding on the air flowing through the humidifying material. To prevent this, it is conceivable to add a sterilizing agent to tap water that is dripped from above the humidifying agent, but in practice it is possible from the economical point of view that the vaporized chemical components may fly into the air. I can't go up.

[0006] The cause of adhesion and deposition of scale on the humidifying material is
This is because the humidifying material contains a considerable amount of water in order to enhance the humidifying effect, and the humidifying material is dried when the humidifier is stopped at night and the calcium contained in the water is scaled.

[0007] Further, the dissolution characteristics of calcium and magnesium, which are scales, are opposite to those of salts, and the lower the water temperature, the larger the amount of dissolution, and the higher the water temperature, the more it precipitates as scale. The humidifier targeted by the present invention is incorporated in the secondary side of the air conditioner coil so as to efficiently remove latent heat of vaporization. In this case, the water temperature absorbed by the humidifier during heating is 30 to 4
This is because the temperature rises to 0 ° C. and the above-mentioned hardened components tend to precipitate.

In order to eliminate the above-mentioned disadvantages, a water purifier is attached to the humidification water supply pipe in part, but the water purifier is relatively expensive, which leads to an increase in cost. Improvement was desired.

The present invention has been made in view of the above-mentioned conventional problems, and a first object thereof is a ventilation type which can prevent bacteria from being generated in a humidifying material by an extremely simple means. It is to provide a water absorbent humidifier in a humidifier.

A second object of the present invention is to provide a water-absorbing humidifier in a ventilated humidifier capable of preventing bacteria and scale from being generated in the humidifier by an extremely simple means.

[0011]

In order to achieve the first object, in the present invention, a water-absorbing humidifier installed in a distribution air passage of an air conditioner and a water supply device for supplying water above the humidifier are provided. In such a ventilation vaporizer, the humidifying material contains copper.

As a means for containing copper in the above-mentioned humidifying material, it is preferable to form the humidifying material by using a wire material in which a copper wire is used as a core material and a water absorbing material is wound or covered on the outer periphery of the core material. , Winding or inserting a copper wire around the water absorbent humidifier,
A powdery or granular copper is attached to the water absorbent humidifier, or a copper plate or a copper net having a large number of openings is used, and the outer periphery of these copper plates or nets or between a plurality of copper plates or between nets is used. That is, the water-absorption / humidification material is disposed in contact with the material.

In order to achieve the above-mentioned second object, in the present invention, in the ventilation type humidifier of the above structure, the water absorbent humidifier contains carbon fiber or metal wire other than copper or activated carbon. .

When the carbon fiber or metal wire is used, it is preferably braided with the copper wire.

[0015]

[Function] It is widely known that a trace amount of copper ion has a function of killing bacteria and fungi, and having a deodorizing and decay preventing function. The present invention utilizes this principle. When the copper contained in the humidifying material comes into contact with the water from the water supply device, copper ions are generated, and due to the action of the copper ions, bacteria or mold are generated in the humidifying material. Are prevented.

When the water-absorption / humidifying material contains carbon fibers or a metal wire other than copper, an electrochemical potential difference is generated between the water-absorbing / humidifying material and copper through the electrolyte water, and the water in the meantime is ionized. Ionization prevents precipitation of calcium, magnesium, silica, etc. in water, and prevents these scales from precipitating on the humidifying material.

If activated carbon is used instead of the carbon fiber or metal wire, in addition to the effect of preventing the scale from adhering, the air from the suction port of the air conditioner can be deodorized.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

The figure shows a ventilated vaporization type humidifier to which the present invention is applied. In the figure, reference numeral 1 denotes a water absorbent humidifier, and this humidifier 1
A water sprinkling pipe 2 is disposed above the water sprinkler, and the water sprinkling pipe 2 is connected to a water pipe (not shown) via a valve. A large number of small holes are formed on the lower surface of the sprinkling pipe 2, and tap water is dropped on the humidifying material 1 through the small holes.
Further, a water receiving tank 3 is installed below the humidifying material 1 and is discharged to the outside through a drainage pipe 4 or circulated above the humidifying material 1 again.

The humidifier 1 has a rear surface arranged in an air conditioner whose illustration is omitted. As shown by an arrow in the figure, the dry air flowing in through the intake port of the air conditioner flows from the rear surface to the front surface of the humidifier. pass. During this time, part of the moisture in the humidifying material is evaporated, and is accompanied by the air flow passing through the humidifying material to be discharged and circulated as humid air in the room.

As the moisturizing material 1, yarn such as fiber yarn having excellent water absorption and water retention (for example, 75% cotton and 2 polyester) is used.
5% synthetic yarn) and copper wire twisted yarn (weight ratio of yarn to copper wire 1:
1) is prepared, a plurality of mesh screens (mesh 10 mm × 10 mm) knitted and woven using the twisted yarn as a material are combined, and these are suspended in a rectangular synthetic resin frame.

The size of the humidifying material 1 is determined in accordance with the size of various air conditioners, and the number of laminated mesh screens is determined in relation to the required effective humidifying amount. The pressure loss caused by the passage is set so as not to impair the effective function of the air conditioner.

In the above structure, when water is dropped from the sprinkling pipe 2 above the frame, a part of the water is absorbed by the water-absorbing thread of the mesh screen, and the remaining water is received by the water receiving tank 3 therebelow. Drop it. While the dry air flowing in from the intake port of the air conditioner enters from the back side of the humidifying material 1 and passes through the front side, a part of the moisture absorbed by the mesh screen is evaporated and the moist air is accompanied by the air flow. Humidify the room as.

At this time, since the copper wire comes into contact with water to generate copper ions, germs and molds generated in the humidifier are killed by the sterilizing action of the copper ions, and the air flow passing through the humidifier 1 Accordingly, it is possible to prevent bacteria and the like from scattering in the room.

In the first embodiment described above, the humidifying material 1 is composed of the synthetic yarn and the twisted yarn of the copper wire in order to generate the copper ions in the humidifying material. However, various modified examples can be considered in the present invention. For example, a copper wire is used as a core material to form a moisturizing material by using a wire material wound or covered with a water absorbent material on its outer periphery, or a copper wire is wound or inserted into a water absorbent moisturizing material, Alternatively, a powdery or granular copper is adhered to the water absorbent humidifier, or a copper plate or a copper net having a large number of openings is used, and the outer periphery of these copper plates or nets or between a plurality of copper plates or between nets is used. You may make it arrange | position a water-absorption humidifying material to this.

In the second embodiment of the present invention, carbon fiber is used in addition to copper as the humidifying material. This carbon fiber may be used in place of the synthetic yarn of the above example to form a copper wire and a twisted yarn, or carbon fibers may be formed at appropriate intervals on a reticulated screen made of the twisted yarn of copper and a synthetic yarn of the above example. May be woven. Further, the moisturizing material may be formed by using the wire material and the carbon fiber in which the copper wire of the above-mentioned embodiment is used as the core material and the water absorbing material is wound or coated on the concentric outer periphery thereof. Also, the copper wire and the carbon fiber are wound around or inserted into the water absorbent humidifier, or the carbon fiber is wound around or inserted into the water absorbent humidifier formed by adhering copper in a powder state or granular form. Good. In this case, it is preferable that the carbon fiber and the copper or copper wire do not come into direct contact with each other.

In the humidifying material of the second embodiment, since copper and carbon fiber have an electrochemical potential difference, when water in the humidifying material is present between these two substances, a voltage is generated to transfer energy. Occurs, during which the water is ionized. The water thus ionized, as is well known, prevents the precipitation of crystals of calcium, magnesium, silica, etc. in water and prevents these substances from adhering to the humidifier as scale.

Although carbon fibers are used in the above embodiment, a metal different from copper, such as aluminum,
Also in the case of a wire made of stainless steel or the like, it can be used instead of carbon fiber because it has an electrochemical potential difference with copper. In this case, since the metal wire does not have liquid absorbency, it is necessary to use it in combination with another material having excellent liquid absorbency.

The third embodiment of the present invention is to use activated carbon in place of the carbon fiber of the above embodiment. In this case, preferably activated carbon particles are attached to the surface or inside of a fiber material having liquid absorbability, and a copper wire is inserted or wound around this fiber material, or copper powder or copper particles are added to this fiber material. It is to contain. Also in this case, it is preferable that the copper wire and the activated carbon do not come into direct contact with each other.
