The number is about 10,000. In addition, these hollow fiber membranes 1
Are not limited to these ranges.

As the hollow fiber membrane 1, a hydrophobic one is preferably used, and a three-layer composite hollow fiber membrane having a three-layer structure in which both sides of a non-porous layer are sandwiched between porous layers is used. Can be. When this three-layer composite hollow fiber membrane is used, the oxygen permeation rate of the sandwiched non-porous gas permeable membrane is 0.6

Thermosetting resin such as phenolic resin, amino resin, unsaturated polyester resin, diallyl phthalate resin, silicone resin, epoxy resin, urethane resin, or thermoplastic resin such as polyethylene resin, polypropylene resin, polyvinyl chloride resin, acrylic resin The ends of the bundled hollow fiber membranes 1 are immersed in these uncured resin liquids, respectively, and after the resin liquids are cured, the cured portions are cut and the fixed hollow fiber membranes 1 are fixed. It is manufactured so that both ends are open. As shown in FIGS. 2 and 3, the shape of the fixing portion 2 is an annular shape corresponding to the convergence form of the hollow fiber membrane 1.

The humidifying unit 10 has a water supply section 3 attached to one fixed section 2 and a water discharge section 4 attached to the other fixed section 2. Each of the water supply unit 3 and the water discharge unit 4 is a pipe made of metal, plastic, or the like, and has a shape corresponding to the convergence form of the hollow fiber membrane 1. As shown in FIG. Has an opening 3a or 4a formed on the outer peripheral side surface thereof, and a mounting through groove is formed in a circular shape in a central portion on one side thereof. The fixing portion 2 is inserted into the mounting through groove, and the hollow fiber membrane 1 is set therein, and is fixed in a liquid-tight manner. At this time, FIG.
As shown in FIG. 2, both ends of the hollow fiber membranes 1, 1,... Are positioned on the internal paths of the water supply unit 3 and the water discharge unit 4 in an open state.

A water supply pipe 5 is attached to an opening 3a of the water supply unit 3, and a drainage pipe 6 is attached to an opening 4a of the water discharge unit 4. FIG. 4 shows the water supply unit 3 and the water supply pipe 5 or the water discharge unit 4 and the drainage pipe 6
It is sectional drawing of the connection part with. The opening end side of the opening 3a of the water supply unit 3 has a connecting portion 3 having a smaller diameter than the diameter of the water supply unit 3 side.
b, the connecting portion 3b has an opening 5a
A water supply pipe 5 that can be locked and detached at is provided.

Each of these openings 3a, 4a has a cylindrical main body through which water flows,
Two or more metal balls 5c to be locked in the coupling groove 3c are attached. The diameter of the metal ball 5c is increased to a diameter at which the connecting portion 3b can be inserted by retreating the slide ring 5d on the outer peripheral portion of the opening 5a. Slide ring 5
d is constantly urged forward by a spring in the opening 5a. By press-fitting the connecting portion 3b into the opening 5a, the coupling groove 3c is locked by the metal ball 5c in the opening 5a, and the tip of the connecting portion 3b is locked by the O-ring 5b. And the water supply pipe 5 are communicated. By retreating the slide ring 5d of the opening 5a, the connecting portion 3b is separated from the opening 5a, and the connection between the water supply unit 3 and the water supply pipe 5 is released. The structure of these connecting parts is the connecting part 4b of the opening 4a of the water discharging part 4.
The same applies to the opening 6a of the drain pipe 6.

If the mechanism for connecting the opening 3a to the opening 5a and the opening 4a to the opening 6a is a mechanism that can be attached and detached with one touch, the connection between the water supply unit 3 and the water supply pipe 5 and the water discharge unit 4 It is preferable because it is easy to attach / detach to / from drain pipe 6. Further, it is preferable that the water supply pipe 5 and the drainage pipe 6 be flexible pipes because the attachment / detachment operation is further facilitated. Since the water supply part 3 and the water supply pipe 5 or the water discharge part 4 and the drainage pipe 6 are detachably formed in this manner, when the humidification unit 10 is mounted on a humidifier, the hollow fiber membrane is formed. The humidification unit 10 can be easily replaced when the performance of the humidification unit 1 is deteriorated due to adhesion of the humidification unit 1. Also, the hollow fiber membranes 1, 1,... Of the humidifying unit 10 thus removed are washed,
Can be used again.

The above-described hollow fiber membrane 1, fixed section 2, water supply section 3
A humidifier 7 for heating the humidifying unit 10 is provided inside the cylindrical humidifying unit 10 including the water discharging unit 4.
Is stored. The heating body 7 has a sheathed heater embedded in the wall surface of a cylindrical housing made of metal.

The sheathed heater has a cord shape in which a nichrome wire and a powder of magnesium oxide, aluminum oxide or the like are contained in a SUS pipe. It generates heat. Since this sheathed heater is in a cord shape, it can be formed in various shapes in accordance with the shape of the humidifying unit 10 and is therefore preferably used. In the case as shown in FIG. 1, it is arranged in a meandering manner in a metal cylinder, and is entirely cylindrical.

The heating element 7 has a humidifying unit 10 on its surface.
When the heating element generates heat, the water in the hollow fiber membrane 1 of the humidifying unit 10 is heated by the heat and evaporates. At this time, in the humidifying member 51 of the present invention, since the humidifying unit 10 and the heating element 7 are integrated, the water quickly becomes water vapor and exudes to the surface of the hollow fiber membrane 1. The distance between the heating body 7 and the hollow fiber membrane 1 can be set arbitrarily according to the target conditions. Further, the heating body 7 and the hollow fiber membrane 1 may be in close contact with each other.

In the humidifying member 51 having such a configuration, when water is supplied to the water supply section 3 of the humidification unit 10 through the water supply pipe 5, the water is supplied to the openings of the hollow fiber membranes 1, 1,. Disperse into the interior from the edge. And the humidification unit 1
, The hollow fiber membranes 1, 1,...
The water in the inside is heated, becomes steam, moves from the inside to the outside of the hollow fiber membrane 1, and is oozed out from the fine pores on the outer surface of the hollow fiber membranes 1, 1,. Then, the remaining water is collected by the water discharge unit 4 and discharged through the drain pipe 6.

Further, since the hollow fiber membrane 1 is mainly made of a hydrophobic material, the water vapor that has been heated and vaporized oozes out to the surface as a gas. At this time, the humidifying unit 1
If air is pumped from the side of the hollow fiber membrane 1, the hollow fiber membrane 1, 1,
..The water vapor on the surface moves into the air and can humidify the air. In this case, dust, dirt, germs, molds, and the like existing in the water cannot pass through the micropores of the hollow fiber membrane, and sterile hygienic humidification that is not contaminated by these substances can be performed. In addition, when a composite hollow fiber membrane 1 having a three-layer structure in which a non-porous gas-permeable membrane sandwiches a non-porous layer between porous layers from both sides thereof is used, inorganic substances dissolved in water do not pass therethrough. Also, no white powder is generated on the surface of the hollow fiber membrane 1 due to the precipitation of inorganic substances. Furthermore, since it is integrated with the heating element 7, the moisture quickly becomes water vapor and the amount thereof is large, so that the air can be humidified quickly and efficiently.

In this case, the sheathed heater is meanderingly arranged in a plane to form a heating body 17, and is arranged in parallel and close to the surface of the hollow fiber membrane 11 of the humidifying unit 20. At this time, when a current is supplied from the power supply 8 to the sheathed heater, the nichrome wire in the sheathed heater generates heat. In this way, the humidifying unit 20 is heated by the heated heating element 17.
In the hollow fiber membrane 11 is heated and becomes water vapor and exudes from the micropores of the hollow fiber membranes 11, 11. Then, the remaining water is collected in the water discharge unit 14.
