Abstract

PURPOSE:To prevent the inner surface of a porous blank of a hydrophobic high molecular weight material from being brought into close contact, by provid ing a bag form hollow structure formed from a porous blank of a hydrophobic high molecular weight material capable of preventing passage of water there through and permitting passage of a water vapor therethrough, and a belt form spacer member inserted in the structure and provided with at least two projected parts at a predetermined interval on both sides thereof. CONSTITUTION:The belt form spacer member 4 provided with at least two projected parts 4a at a predetermined interval on both sides thereof is inserted in the hollow structure 1. The average diameter of innumerable minute holes present in the sheet member of the porous blank 1a of the hydrophobic high molecular weight material is preferably 0.1-10mum, in order to permit free passage therethrough of water vapor while preventing passage therethrough of liquid water. The hollow structure 1 is formed in a bag form, by bending the sheet member and sealing end faces of the sheet member exclusive of a water supply port 2 by adhesion or fuse-welding.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a humidifier used for air conditioning.

[Conventional technology]

FIG. 3 is a perspective view showing a conventional humidifier of this type. In the figure, (1) is a bag-like hollow structure, which is made by stacking sheets of hydrophobic polymer porous material (LA) and sealing the peripheral portions by gluing or heat-sealing. (2) shows the water supply port, and (3) shows the water drain port.

Further, (a) and (b) in the figure indicate the direction of air flow.

Next, the operation will be explained. The water supplied from the water supply port (2) is supplied to the inside of the hollow structure (1) made of a porous element ((la) of hydrophobic polymer, and the air existing inside is The supplied water escapes through the fine pores of the porous material (la) made of polyester and is filled with the water.Meanwhile, the dry air supplied from a blower (not shown) etc. fills the surface of the hollow structure (1). pass through.

At this time, since water vapor can freely pass through the fine pores of the hydrophobic polymer porous material (1a), the water in the hollow structure (1) is dried by the drying material supplied from a blower, etc. Humidified air is obtained by being contained in the air.

[Problem that the invention seeks to solve]

As mentioned above, conventional humidifiers are constructed in the form of a bag using a sheet material made of a porous hydrophobic polymer q(la), so before water is supplied, the inner surface of the sheet material is in close contact with the However, it takes time for the water supplied from the water supply port to fill the interior of the hollow structure, and the supply water pressure is also required.

[Means for solving problems]

The humidifier according to the present invention includes a bag-like hollow structure made of a porous material made of a hydrophobic polymer that can prevent the passage of water and allow the passage of water vapor, and a humidifier that is inserted into the hollow structure,
It is provided with a band-shaped spacing member having at least two protrusions at a predetermined interval on both sides.

[Effect]

In this invention, a band-shaped spacing member having two or more convex portions on both sides is inserted inside the hollow structure, so that the porous bag-shaped hydrophobic polymer constituting the hollow structure is inserted. In order to prevent the inner surface of the material from coming into close contact with each other and to prevent an increase in water supply resistance during water supply, the time for the supply water to fill the inside of the hollow structure is quick.

〔Example〕

FIG. 1 is a cross-sectional perspective view of a humidifier showing an embodiment of the present invention. In the figure, (1) is a porous material made of hydrophobic polymer (
1a), and this hollow structure (1) has strip-shaped gaps (4a) having two or more convex portions (4a) at predetermined intervals on both sides. Parts (4)
is inserted. The above hydrophobic polymer porous material (l
For a), for example, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, stream ester, and fluororesin are used as materials, and the average pore diameter of the countless micropores present in these sheet materials is In order to allow liquid water molecules (like water molecules) to pass through freely, but not to allow liquid water (liquid water molecules) to pass through, it is desirable that the range is 0.1 p; 18 to 10 p. In addition, the hollow structure (1) is made by bending a sheet material of a porous material (LA) made of hydrophobic polymer and sealing each end surface of the sheet material except for the water inlet (2) by gluing or heat-sealing. is,
It has a bag-like structure.

FIG. 2 is a perspective view of a humidifier showing another embodiment of the present invention, in which the band-shaped spacing member inserted into the hollow structure (1) is folded back at a predetermined interval. , an air path through which dry air supplied from a blower (not shown) or the like passes. Although not shown in the figure, the humidifier is fixed by an auxiliary part in order to maintain its shape. In the humidifier configured as above, the hollow structure (1) has convex portions (4a) on both sides inside (1b).
Since the strip-shaped spacing member (4) having a diameter of Therefore, it is possible to prevent an increase in water supply resistance during water supply, so that the time required for the hollow structure (1) to be filled with the supply water is shortened.

〔Effect of the invention〕

As explained above, the present invention includes a bag-like hollow structure made of a porous hydrophobic polymer material that can prevent water from passing through and allow water vapor to pass through, and a bag-shaped hollow structure that is inserted into the inside of this hollow structure. Since the humidifier is constructed by providing a band-shaped spacing member having at least two protrusions at a predetermined interval on both sides, the porous hydrophobic polymer constituting the hollow structure Since it is possible to prevent the inner surface of the material from coming into close contact with each other and therefore prevent an increase in water supply resistance during water supply, it has the effect of shortening the time until the interior of the hollow structure is filled with supplied water. .

In addition, since the spacer to be inserted is strip-shaped, the thickness of the hollow structure can be reduced, and the overall structure can be reduced.
Since the band-shaped spacing member does not shift to one side inside the hollow structure, there is an effect of keeping the thickness of the hollow structure uniform.
