Description

[Detailed description of the invention]

[0001]

[Industrial application] Heating or cooling a room with a stove or air conditioner reduces the humidity, so that the elderly, infants, and sick people can easily hurt their throats and bronchi. In recent years, humidifiers have been widely used to compensate for the decrease in humidity in order to alleviate such a situation. There are two types of humidifiers: a system that raises the humidity by boiling and evaporating water, and a system that forms water particles by supersonic waves and discharges them into the air. This invention is based on the idea that the former type of humidifier reduces heat conduction by accumulating scale (evaporation residue due to substances dissolved in water) in or around the heating pot as the service period is prolonged. The present invention relates to a novel scale collecting material used for collecting this scale, which has problems such as worsening the effect.

2. Description of the Related Art FIG. 15 shows an example of the prior art, in which a nonwoven fabric 43 is formed into a cylindrical shape and a scale collecting material 42 is formed.
And FIG. 16 shows a state in which the scale collecting material 42 is mounted on a humidifier 46. The main part of the humidifier 46 is composed of a heating pot 23 equipped with a heater 22 and a cover 25, and a scale collecting material 42 is mounted inside the cover 25 with its lower end immersed in the water 24 of the heating pot 23. ing. Then, the water 24 in the heating pot 23 is heated by the heater 22 and boiled to generate steam, thereby performing humidification. The loss of the water 24 in the heating pot 23 due to evaporation is automatically supplied (not shown). If the water 24 continues to evaporate for a long period of time, a scale is gradually formed in the heating pot 23, and the scale permeates the scale collecting material 42 together with the water and is collected.

FIG. 17 shows another example of the prior art, in which a non-woven fabric 43 is provided with a circular scale collecting material 44 having a hole 45 formed therein.
It is. In this example, the scale collecting material 44 is mounted in the heating pot 23 of the humidifier 47 in a state of being entirely immersed in water 24 as shown in FIG.

[0004] The scale is gradually collected and accumulated in the scale collecting material as the period of use becomes longer. However, the user of the humidifier needs to renew the scale before the scale collecting capacity reaches the limit. It is to be replaced with collecting material.

[0005]

[0005] By the way, as the conventional scale collecting material, a non-woven fabric formed by forming a polyester fiber, a polypropylene fiber or the like into a felt shape is used.
There were the following problems.

[0006] The nonwoven fabric forming the scale collecting material is
Due to the hydrophobic synthetic fiber, the permeability of water into the scale collecting material was poor, and the scale was deposited only on the surface layer of the scale collecting material. As a result, the scale collecting ability was low. Therefore, the user of the humidifier has to change the scale collecting material frequently in a short time, which is very complicated. Further, if the scale collecting material is continuously used without being exchanged, a large amount of scale is deposited on the heating pot or its surroundings, resulting in a problem that the heating efficiency is lowered and the humidification capacity is lowered. In addition, in the case of a scale collecting material formed into a cylindrical shape, when attached to a humidifier, the nonwoven fabric is soft, so it is difficult to maintain the cylindrical shape because of its flexibility, and it loses shape and prevents evaporation of water in the humidifier,
There were problems such as the lower end detaching from the water surface and it was difficult to collect the scale. This invention aims to solve these problems of the prior art.

[0023]

The scale collecting material of the present invention is formed of a porous plate having a large number of small holes or narrow holes. It easily penetrates into the inside of the porous plate through a large number of small holes or narrow holes, and acts to filter and collect the scale. Therefore, not only the surface layer of the porous plate but also the entire inner layer including the inner layer effectively acts as a scale deposition space.

Further, another scale collecting material of the present invention is formed of a porous plate having a number of substantially parallel zigzag folds, so that a porous plate having an area larger than that of the prior art is adopted. The large surface area makes it possible to increase the contact area with water and facilitates the penetration of water containing scale, while the large volume of the porous plate has the effect of increasing the scale deposition space. is there.

Further, the present invention provides a porous plate made of a multi-layer nonwoven fabric which is a laminate of a web layer and a water-absorbing base fabric, in which a number of small holes or narrow holes are formed, or a number of substantially parallel holes are formed. Since a scale collecting material having zigzag folds can be used, the water containing the scale is absorbed by the water-absorbing base cloth and easily diffused throughout the porous plate.

[0026]

[Effect] Since the scale collecting material of the present invention is formed of a porous plate having a large number of small holes or narrow holes, the prior art scale collecting material has water permeability into the inside. Is bad,
As a result of the scale being deposited only on the surface layer, the trapping ability of the scale was low, but water containing the scale from many small holes or narrow holes easily penetrated into the inside of the porous plate, The scale is deposited inside and the collecting ability of the scale is remarkably improved, and the replacement life of the scale collecting material can be prolonged.

Further, another scale collecting material of the present invention is formed of a porous plate provided with a large number of substantially parallel zigzag folds. As a result, the contact area with water can be increased, and the volume of the porous plate can be increased, so that the water containing the scale can be easily permeated and the trapping ability of the scale can be remarkably improved.

The scale collecting material of the present invention can be provided with both a large number of substantially parallel zigzag folds and a large number of small holes, so that the scale collecting ability is further improved. .

Further, the scale collecting material of the present invention can be formed by forming a large number of small holes or narrow holes in a porous plate made of a multilayer nonwoven fabric which is a laminate of a web layer and a water-absorbing base fabric. Alternatively, since it can be a porous plate provided with a number of substantially parallel zigzag folds, water containing scale is absorbed by the water-absorbing base cloth and diffuses and permeates more easily throughout the porous plate. As a result of depositing the scale, the ability to collect the scale is further improved.
