This is shown on the base 4'. A metal heat conductor layer 2 ′ having a metal truncated cone shape for fitting to the outer surface of a conical heat source block 5 ′ as a heating source mounted via a heat insulating material 7 ′; The heat conductor layer 2 'is formed by a water-absorbing layer 3' which is fitted on the outer surface of the heat-conductive layer 2 'and closely sucks water from the reservoir tank portion 6' by capillary action.
[0003]
[Problems to be solved by the invention]
However, this type of water-absorbing element 1 ′ has a problem to be further improved. Specifically, since the water absorbing layer 3 'expands during water absorption, and the adhesion between the water absorbing layer 3' and the heat conductor layer 2 'decreases, the heat from the heat source block 5' to the water absorbing layer 3 'is reduced. This is a point in which the conduction of water becomes insufficient, and in some cases, a predetermined amount of transpiration cannot be obtained.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0007]
In FIG. 1, reference numeral 1 denotes a water absorption element of the present invention, and the water absorption element 1 is a water absorption type heating humidifier equipped with a truncated cone-shaped heat source block 5 in which a reservoir tank 6 is arranged on the outer periphery of the lower part. It fits on the heat source block 5 and consists of a water absorbing material 8 and a rubber-like elastic body 9, which will be described in detail later. In FIG. 1, 4 is a base, and 7 is a heat insulating packing.
[0008]
The water-absorbing material 8 of the water-absorbing element used in the present invention has a shape such as a woven fabric, a knitted fabric or a non-woven fabric made of a water-absorbing material such as rayon or cotton, which is rich in water-absorbing material. Punch nonwoven fabric is suitable, and the thickness and density are preferably relatively thick and high density from the viewpoint of securing a sufficient amount of water absorption and evaporation during heating, for example, a basis weight of 300 to 1500 g / It is preferable to use one or a plurality of m ^{2 having} a thickness of about ² to 10 mm.
[0009]
The shape of the water-absorbing material 8 is a fan-like shape in which a truncated conical cylinder is developed as shown in FIG. The length of the water-absorbing material 8 at this time is such that, for example, when the obtained water-absorbing element 1 is mounted on the frustoconical heat source block 5 of the water-absorbing and heating type humidifier, the lower end of the water-absorbing material 8 is the reservoir tank. It is made to immerse under the water surface in the part 6, and this makes it possible to suck up the water in the reservoir tank part 6 by capillary action.
[0010]
Further, the rubber-like elastic body 9 of the water-absorbing element 1 used in the present invention may be any material having rubber elasticity such as natural rubber, synthetic rubber, and polyurethane, and in particular, a water-absorbing rubber-like elastic body such as polyurethane is used. desirable.
[0011]
The water-absorbing element 1 of the present invention comprises the water-absorbing material 8 and a rubber-like elastic body 9, and has a fan-like shape in which a truncated conical cylinder is developed as shown in FIGS. The water absorbing material 8 is fixed by sewing, bonding, or the like so that both side edges of the water absorbing material 8 are connected by a rubber-like elastic body 9, thereby improving the adhesion to the truncated cone-shaped heat source block. The shape of the rubber-like elastic body 9 may be fixed to all the side edges of the water absorbing material 8 or may be partially fixed.
[0012]
Furthermore, the water-absorbing element of the present invention can have two or more layers by adding other layers to the outside or the inside of the water-absorbing material 8, for example, heat transfer from the heat source block to the inside of the water-absorbing material 8. It is also possible to closely contact a thin sheet-like material that does not hinder.
[0013]
In addition to directly covering the heat source block, the water absorbing element of the present invention can also be used by covering the heat source block with a heat conductor and covering it.
[0014]
The water-absorbing element 1 of the present invention obtained as described above is in close contact with a frustoconical heat source block 5 provided in a water-absorbing heating humidifier as shown in FIG. The lower end portion is immersed in the reservoir tank portion 6 disposed on the outer periphery of the lower portion, and the water sucked up by the capillary action can be evaporated.
[0015]
In short, the water-absorbing element 1 of the present invention can absorb a large amount of water by the water-absorbing material 8, and the water-absorbing element and the heat source block or a heat conductor covering the water-absorbing element are fitted on both side edges of the water-absorbing material. Since the rubber-like elastic body is fixed so that the tension to act becomes, the water-absorbing element and the heat source block are always tightly fitted, and the absorbed water may be in sufficient contact with the heat heated by the heat source block. Is possible. Even if the water-absorbing material swells due to water absorption, the close contact between the water-absorbing element and the heat source block can be maintained by the tension of rubber elasticity, and heat conduction is performed extremely effectively. In this way, a large amount of water contained in the water absorbing material of the water absorbing element is heated, and humidified steam is generated.
For this reason, the water absorption element of this invention can maintain the transpiration amount stabilized for a long time.
[0016]
【Example】
Hereinafter, the present invention will be specifically described by way of examples.
[0017]
Example When a needle punched nonwoven fabric (weighing 700 g / m ² , thickness 4 mm) 8 consisting of 70% by weight of rayon fiber and 30% by weight of polyester fiber is wound along the outer peripheral surface of the heat source block, between both side edges. The truncated cone was cut into a developed shape as shown in FIG. 4 so that a gap of 20 mm was formed. Both side edge portions were sewn and connected to a rubber-like elastic body 9 having a width of 10 mm and a length of 117.6 mm to obtain a truncated cone-shaped water absorbing element shown in FIG.
[0018]
Comparative Example When a needle punched nonwoven fabric (weighing 700 g / m ² , thickness 4 mm) composed of 70% by weight of rayon fiber and 30% by weight of polyester fiber is wound along the outer peripheral surface of the heat source block, both side edges thereof come into contact with each other. As shown in FIG. 6, the truncated cone was cut into a developed shape. The both side edges were sewn and connected to form a frustoconical water-absorbing element.
[0019]
The water-absorbing element obtained in the above-mentioned examples and comparative examples is attached to the heat-source block of a water-absorbing heating humidifier (Mitsubishi Heavy Industries Cold Equipment Co., Ltd., Beaver Steam Fan Humidifier SHE403R-H type) Continuous humidification operation was performed at room temperature of -25 ° C for 8 hours a day. When the water-absorbing element of the example was used, steam was generated 3 minutes after the start of heater energization. Furthermore, the humidification operation was performed smoothly over 60 days, and the humidification amount (transpiration amount) was stable in the range of 2700 to 3000 g per 8 hours per day.
[0020]
On the other hand, when the water-absorbing element of the comparative example was used, steam was generated in 3 minutes after starting the heater energization in the initial stage of operation, and the humidification amount (transpiration amount) was stable in the range of 2700 to 3000 g per 8 hours per day. . However, as the operation was repeated, the time until the generation of steam became longer and the amount of transpiration decreased, and it was impossible to obtain a humidified amount after 5 days. The water absorbing element after the experiment expanded, and a gap was generated between the water absorbing element and the heat source block.
[0021]
【The invention's effect】
