DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier for processing air into a humidified atmosphere by passing the air, and a humidifier for supplying the processed air as humidified air through the humidifier. is there.

[0002]

2. Description of the Related Art An apparatus for generating air in a humid atmosphere includes:
There are a natural evaporation type, an electric heating type, a water spray type, an ultrasonic type and the like, all of which have some problems. That is, the spontaneous evaporation type has a problem that the humidifying ability is small, and the electric heating type has a problem that the running cost is increased, and the water spray type has a low humidification efficiency and tends to be large in size. It is known that the ultrasonic type has a short service life despite the high initial cost, and it is also easy to disperse various bacteria and calcium carbonate fine powder in water.

[0003] Among them, those of the natural evaporation type have a low humidification capacity, such as low running cost and initial cost, high scattering of germs and fine powder of calcium carbonate, and high safety. There is much to gain. Based on these facts, various devices for improving the humidification capacity have been disclosed in, for example, JP-A-60-171337 and JP-A-61-175421.
JP-A-61-237942, JP-A-6-237942
This has been performed as disclosed in Japanese Patent Application Laid-Open No. 50581 and Japanese Patent Application Laid-Open No. Hei 6-213485.

[0004] The humidifiers disclosed in the above publications are:
Basically, the air to be humidified and the water are not in direct contact with each other, and the evaporation area is enlarged. That is, as shown in FIGS. 22 and 23, the tubular film body 101 is formed by a moisture permeable film that does not transmit water but transmits water vapor. A spacer is provided in the tubular film body 101, and a space having a thickness of several millimeters in which water can enter is held by the spacer. A corrugated spacing plate 102 for holding a space for supplying air to be humidified is superimposed on the tubular film body 101 and spirally wound to form a humidifier 103. With such a configuration, compared to the conventional natural evaporation type that supplies water to an open container or a plate or cloth made of a hydrophilic material, there is no scattering of germs and fine powder of calcium carbonate, and a high humidification capacity can be obtained by expanding the evaporation area. ing.

However, the natural evaporation type humidifier employing the tubular film body 101 also has some problems. For example, the spacing plate 102 is an important component for maintaining a space through which air to be humidified passes, but the spacing plate 102 made of a corrugated corrugated plate is limited in its structure by the size of a wave crest with respect to a wave height. Yes, the wave crest spacing with respect to wave height is not very large. Therefore, as a whole, the space to be supplied with air is narrowed, and the resistance of the humidified air with respect to the supply of air is considerably increased. Further, since the tubular membrane 101 is spirally wound, water used for humidification is supplied from a water supply tank 104 installed above the humidifier to the tubular membrane 10.
1, water must be supplied by the water supply tube 105,
In order to smoothly supply water to the entire tubular film body 101, an auxiliary water supply tube 106 for venting air is also required. Therefore, when a humidifier is configured by arranging a plurality of humidifiers 103, the water supply tube 105 and the auxiliary water supply tube 106 are connected to each of the humidifiers 103, and the configuration becomes complicated, and the humidifier becomes complex. Inspection and replacement of the humidifier 103 are troublesome, and the water supply tube 105 and the auxiliary water supply tube 106 are easily damaged when the humidifier 103 is attached or detached.

Most of the problems of the humidifier 103 in which the tubular film body 101 is formed in a spiral form are, in recent years, provided with an air supply layer through which the processing air passes and a water retaining layer formed by a flat water guide made of a moisture permeable membrane. The problem has been solved by the development of a humidifier having a laminated structure configured as follows. In this humidifier, each water retention layer is sealed with a rigid water-permeable member made of a perforated plate that is rigid and capable of passing water, in a bag-like membrane formed by a moisture-permeable membrane that does not transmit water but transmits water vapor. And it is comprised by the flat water guide which both combined. This humidifier has high humidification ability and can be reduced in weight.

[0007]

A humidifier having a laminated structure in which the above-described air supply layer and a water retaining layer made of a flat water guide made of a moisture permeable film are provided every other layer has excellent humidification functions. In the case where a plurality of conventional humidifiers are arranged and used, a water supply hose must be individually provided for each humidifier, and the humidifiers are individually arranged in a compact hexahedron and arranged in the apparatus. In this case, the connection of the individual humidifiers is difficult, and the inspection and replacement of the humidifier are more difficult to be performed with the humidifier at the back, so that the operability related to attachment / detachment is deteriorated.
