Abstract

(57) [Summary] [Purpose] The conventional scale adsorbent used in humidifiers has poor permeability of water to the inside, and as a result of the scale depositing only on the surface layer, the scale adsorbing ability is low and short-term. I had to replace the scale collector with a new one in between,
Further, if the replacement is neglected, a large amount of scale is deposited in the heating pot, which lowers the heating efficiency and eventually the humidifying ability. The present invention aims to solve these problems. [Structure] A scale collecting material comprising a porous plate having a large number of small holes or narrow holes, or a porous plate having a large number of substantially parallel zigzag-shaped folds.

[Industrial applications]

 When a room is heated or cooled with a stove or air conditioner, the humidity drops, so it is easy for the elderly, infants, and sick people to hurt their throat and bronchi. Humidifiers are becoming widespread in recent years to compensate for the decrease in humidity in order to mitigate this situation. There are two types of humidifiers: a method of boiling and evaporating water to increase the humidity, and a method of supersonic sounding water into fine particles that are discharged into the air. In this device, the former type of humidifier reduces the heat conduction by accumulating scale (evaporation residue by a substance dissolved in water) in or around the heating pot as the usage period is prolonged. However, there are problems such as deterioration of the evaporation effect, and the present invention relates to a novel scale trapping material used for trapping this scale.

[Prior art]

 FIG. 15 shows an example of a conventional technique, in which a nonwoven fabric 43 is formed into a cylindrical shape to serve as a scale collecting material 42. Further, FIG. 16 shows a state in which the scale collecting material 42 is attached to the 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. The scale trapping material 42 inside the cover 25 has its lower end immersed in the water 24 of the heating pot 23. It is installed. Then, the water 24 in the heating pot 23 is heated by the heater 22 and boils to generate steam, thereby humidifying. The amount of water 24 in the heating pot 23 lost by evaporation is automatically replenished (not shown). When the water 24 continues to evaporate for a long period of time, a scale is gradually formed in the heating kettle 23, but the scale penetrates into the scale collecting material 42 together with the water and is collected.

FIG. 17 shows another example of the prior art, which is a circular scale collecting material 44 in which a hole 45 is formed in the nonwoven fabric 43. In this example, as shown in FIG. 18, the scale collecting material 44 is mounted in the heating pot 23 of the humidifier 47 with the whole being immersed in the water 24.

The scale collecting material gradually collects and accumulates the scale as the period of use becomes longer. However, the user of the humidifier can use the new scale before the capacity of the scale reaches its limit. It is to be replaced with a trapping material.

[Problems to be solved by the device]

 By the way, a non-woven fabric in which a polyester fiber, a polypropylene fiber or the like is formed in a felt shape is used as a conventional scale collecting material, but there are the following problems.

The non-woven fabric forming the scale-collecting material is a hydrophobic synthetic fiber, so that the permeability of water into the interior of the scale-collecting material is poor, and the scale is deposited only on the surface layer portion of the scale-collecting material. As a result, the ability to collect scale was low. Therefore, the user of the humidifier has to replace the scale trapping material frequently after a short time, which is very complicated. Further, if the scale trapping material is used without being replaced, a large amount of scale will be deposited in or around the heating pot, which will lower the heating efficiency and eventually the humidifying ability. In addition, in the case of a scale collector formed into a cylindrical shape, when it is attached to a humidifier, it is difficult to maintain the cylindrical shape due to the softness of the nonwoven fabric, which may cause the shape to collapse and prevent evaporation of water in the humidifier. There was a problem that scales were difficult to collect because they separated from the surface of the water. This invention aims to solve these problems of the prior art.

[Action]

 Since the scale-collecting material of this invention is formed of a porous plate having a large number of small holes or narrow holes, the water containing the scale in the heating pot of the humidifier has a large number of small holes. It easily penetrates through the holes or narrow holes into the inside of the porous plate and acts to filter and collect the scale. For this reason, not only the surface layer of the porous plate but also the whole including the inner layer acts effectively as a scale deposition space.

In addition, another scale collecting material of the present invention is formed of a porous plate provided with a large number of substantially parallel zigzag folds, and thus a porous plate having an area larger than that of the prior art is adopted. The large surface area allows a large contact area with water to facilitate the permeation of water containing scale, and the large volume of the porous plate has the effect of increasing the scale deposition space. is there.

Further, according to the present invention, a large number of small holes or narrow holes are formed in a porous plate made of a multilayer nonwoven fabric which is a laminate of a web layer and a water-absorbent substrate, or a large number of substantially parallel holes are formed. Since it can be used as a scale-collecting material having a zigzag fold, water containing scale is also absorbed by the water-absorbent base fabric and easily diffused throughout the porous plate.

【effect】

 Since the scale trapping material of the present invention is formed of a porous plate having a large number of small holes or narrow holes, the scale trapping material of the prior art has poor permeability of water into the inside. As a result of the scale being deposited only on the surface layer, the ability to collect the scale was low, whereas the water containing the scale easily penetrates into the porous plate through a large number of small holes or narrow holes. As the scale is deposited inside, the scale collection ability is greatly improved and the replacement life of the scale collection material can be extended.

In addition, another scale collecting material of the present invention is formed of a porous plate provided with a large number of substantially parallel zigzag folds, and therefore a porous plate having an area larger than that of the prior art is adopted. As a result, the large contact area with water and the large volume of the porous plate facilitate the permeation of water containing scale, and the scale's collection ability is greatly improved.

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

Further, the scale collecting material of the present invention is such that a large number of small holes or narrow holes are formed in a porous plate made of a multi-layered nonwoven fabric which is a laminate of a web layer and a water-absorbent substrate. Alternatively, a porous plate with a large number of substantially parallel zigzag folds can be used, so that water containing scale is absorbed by the water-absorbent base fabric and easily diffuses and permeates through the entire porous plate. As a result of depositing scales, the ability to collect scales is further improved.
