DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing air from a humidifying water passage for a humidifier.

[0002]

2. Description of the Related Art A water channel made of a porous hydrophobic polymer material can effectively achieve the purpose of humidification by being combined with a blowing mechanism, and various improvements have been known. (JP-A-61-72948, JP-A-61-72949, and JP-A-61-180842). With the conventional humidification water flow path unit, it is difficult to replace the air in the flow path with water, and when replacing the air in the flow path with water, there is also a problem that air pools can be formed in the flow path. there were.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air bleeding method which makes it easy to replace air with water when supplying humidifying water in a humidifying water flow path for a humidifier.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have completed the present invention. That is, according to the present invention, a tube made of a porous hydrophobic polymer material is inserted into the hollow unit forming the humidifying water flow path of the humidifier, and the air in the hollow unit is supplied through the tube when the humidifying water is supplied. The method for releasing air in the humidifying water flow path for a humidifier, characterized by discharging air to the outside, is provided.

【Example】

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a humidifying water channel, which is formed by winding a series of tubes made of a porous hydrophobic polymer material into a spiral shape connected to a rising portion. In addition, one end corresponding to the center of the spiral is closed, and a saucer-shaped water supply portion 2 having an open upper surface is formed at the upper end of the rising portion, which is the other end, by swelling. The humidification water flow path 1 is suspended downward with the water supply section 2 as an upper end, and flows air to be humidified in a direction indicated by an arrow in FIG. To change to the required humidified air. In the present embodiment, the tube forming the humidification water flow path is formed in a structure in which a hydrophilic continuous film 4 is laminated on the inner surface of a porous hydrophobic polymer material 3 as shown in FIG. The humidified water 5 is filled inside the hydrophilic continuous film 4 as a layer. In this case, any porous polymer material can be used as long as the porous hydrophobic polymer material 3 is hydrophobic and has a water pressure enough to prevent leakage of internal water. Since this material is required to have a water resistance of 50 mm or more, preferably 100 mm or more, the use of a porous fluororesin is preferable, and the use of porous polytetrafluoroethylene is particularly preferable. Further, a fluororesin such as a copolymer of tetrafluoroethylene and perfluoroalkyl perfluorovinyl ether (PFA) and polyvinyl fluoride can also be used effectively. As the hydrophilic continuous film 4 provided on the inner surface of the flow path, a polyurethane-based resin containing 30% or more by weight of an oxyethylene group and a prepolymer thereof, a polyester-based resin containing 30% or more by weight of an oxyethylene group, and a polyester resin thereof Prepolymers, resins containing a sulfonic acid group, an amino group, a hydroxyl group, or a carboxyl group as a terminal group or a pendant group (for example, ion exchange resins having a flexible shape) and the like can be used (for example, A resin coating as disclosed in JP-B-60-39014 can be used. The thickness of the hydrophilic continuous coating is usually 3 to
It is 400 μm, preferably 5 to 30 μm. In addition, the moisture permeability is at least 1000 g / m ² · day or more,
Preferably, it is 5 × 10 ^{3 to} 9 × 10 ⁶ g / m ² · day. Although the shape of the humidifying water flow path 1 is shown in FIG. 1 as a spiral shape formed by a tube, the shape is not limited to a spiral shape, and may be an arbitrary curved tube. May be in the shape of a bag in which the periphery is sewn. In the present embodiment, as shown in FIG. 3, a series of narrow lower ends made of a series of hydrophobic polymer materials bent to match the shape of the humidifying water channel 1 shown in FIG. An air bleeding member 6 formed by inserting a tube concentrically is provided. The inner diameter of this tube is 1 to 20 mm, preferably 4 to 8 mm. The air vent member 6 can be of various shapes according to the shape of both paths. The material used for the air vent member is the same as the hydrophobic polymer material used for the water flow path, but the hydrophilic continuous film is not formed. Therefore,
This component requires a higher water pressure resistance, typically 400
What is necessary is just to comprise so that it may have a water pressure of more than mm water column, more preferably more than 500 mm water column. FIG. 4 shows a humidification water flow path 1 formed in a corrugated curved tube and having an air vent member 6 provided therein, and each part is indicated by the same reference numeral as in FIG. According to the configuration shown in FIGS. 3 and 4, the air in the flow path is promptly collected by the air release member 6 at the stage of filling with water at the start of use, and the air can be promptly replaced with water.

[0006]

According to the method for removing air from the humidifying water channel for a humidifier according to the present invention, air in the channel is immediately collected by a tube made of a porous hydrophobic polymer material at the stage of filling with water at the start of use. Thus, the air replacement with water can be performed promptly.
