Problems solved by technology

[0004] This kind of hygroscopic filter, because minerals such as silicon, calcium, and magnesium contained in tap water will precipitate on the hygroscopic filter, hindering the use of capillary phenomenon to absorb water, so after long-term use, the hygroscopicity will decrease. bad situation

Embodiment 1

[0055] (Embodiment 1) Production of suction and release moisture filter

[0056] Ethanol and 1N hydrochloric acid were added to tetraethoxysilane for hydrolysis to prepare a binder solution. Mix talc and 1,1'-hexylidene bis[5-(4-chlorophenyl)biguanide] dihydrochloride as an antibacterial agent into the adhesive solution, and Albiline as an antifungal agent, and stir with a ball mill Dispersion was carried out for 5 hours to prepare a slurry.

[0057] The obtained slurry was charged into a sprayer for coating, and sprayed on both the front and back sides of the polyurethane foam and ceramic honeycomb substrate. Then, it was dried at about 100° C. for about 20 minutes to obtain a hygroscopic filter.

[0058] The foaming polyurethane with foaming density of 6 holes / 25mm, 6-10 holes / 25mm, 11-17 holes / 25mm, and 17-23 holes / 25mm was used to make hygroscopic filters. If the foaming density is 17-23 holes / 25mm or more, the pore interval of the foamed polyurethane is too small, and ...

Embodiment 2

[0060] (Embodiment 2) Humidifier

[0061] image 3 and Figure 4 Shown is a simplified cross-sectional view from the front and side of the humidifier. The humidifier 31 includes an air blower 32 as an air blower, a hygroscopic filter 33 , and a water tank 34 . An air heating unit 35 serving as an air heating unit is disposed between the air blowing unit 32 and the moisture absorbing and desorbing filter 33 . The cylindrical hygroscopic filter rotates around the shaft 36 . The dry air sucked into the humidifier 31 by the blower unit 32 is heated to about 50° C. by the air heating unit 35 , and passes through the moisture absorbing and desorbing filter. At this time, the hygroscopic filter 33 is in a wet state by receiving water from the water tank 34, so the water is vaporized, and humidified air is supplied to the downstream side.

[0062] The humidification device was equipped with the hygroscopic filter produced in Example 1, and the device was operated to measure the h...

Abstract

The present invention provides a humidifier capable of maintaining a humidification capacity even when there are deposits on a moisture absorbing and releasing filter, and not needing maintenance fora long period of time in regard to a humidifier humidifying a room. In the moisture absorbing and releasing filter 11, an inorganic material 15 with a particle diameter of 2-55 [mu]m is carried on a base material 13 having a void 12 allowing passage of air, and a surface is formed into an uneven part 16. Since a moisture absorbing and releasing property in the surface is superior, and sucking of water using the capillary phenomenon is not used, the moisture absorbing and releasing filter 11 with almost no deterioration in the humidification capacity due to adhesion of mineral components can beprovided. By using the moisture absorbing and releasing filter 11, the moisture absorbing and releasing filter 11 and the humidifier not needing maintenance for a long period of time can be provided.

Description

technical field [0001] The present invention relates to a hygroscopic filter and a humidifier using the filter. Background technique [0002] An example of a conventional humidifier is shown in Figure 6 . Generally known is a humidification system in which a moisture absorbing and desorbing filter 602 made of nonwoven fabric is placed in a humidifier 601 in a state where a part of the lower part is immersed in water 604 in a water tank 603 . The hygroscopic filter 602 sucks the water 604 in the water tank 603 by capillary phenomenon, and the dry air introduced into the humidifier 601 by the air supply unit 605 along the direction 606 indicated by the arrow passes through the non-immersed part 602a of the hygroscopic filter 602. At this time, the water sucked by the hygroscopic filter 602 is vaporized to increase the humidity in the air, and this high-humidity air is supplied into the room (for example, Japanese Patent Application Laid-Open No. 2000-356373). [0003] In th...
