[0002]
[Prior art]
In a conventional humidifier, a water conveyance member made of a sheet-like porous material is enclosed in a bag-like film formed by a moisture permeable membrane that allows water vapor to pass through, and a flat water conveyance body with a composite structure in which both are combined is constructed. is doing. Humidification capable of passing water by joining a plurality of ribs forming a plurality of air passages parallel to each other on one surface of the water conduit and a water supply member having a water supply hole communicating with the water conduit that supplies water to the inside.

[Problems to be solved by the invention]
As described above, in order to manufacture a conventional humidifier, it is usually necessary to stack a plurality of humidifying functional bodies configured by joining dozens of water guide members, ribs, and water supply members, The assembly process will be diversified. In addition, since the water guide member is enclosed in a bag-like membrane formed by an extremely thin moisture permeable membrane, its surface is easily damaged, and the reliability of the humidifier, which is a finished product, is reduced after many steps. There is a risk of connection. Furthermore, the conventional humidifier is manufactured through many manufacturing processes as described above, and the overall shape depends on the shape of the water guide member, rib, and water supply member itself, so the design change such as a shape change etc. In order to produce a large number of models at once, a major review of the manufacturing process is inevitable, and there has been a problem that it has not been possible to sufficiently meet the recent demand for multi-model small-volume production.
[0005]
Further, in the above-described conventional humidifier manufacturing process, an adhesive is usually used at the time of joining the water guiding member, the rib, and the water supply member, and at the time of stacking the humidifying functional body constituted by joining them. ing. Since the properties of this adhesive are likely to change due to temperature, humidity, etc., if the number of times of bonding is large as described above, the seal around the water supply holes and water passage holes may not be completely achieved depending on the manufacturing environment of the humidifier. There is a case. Further, even when the seal around the water supply hole and the water passage hole is completely made at the time of manufacturing the humidifier, the seal may be incomplete due to a change in properties of the adhesive depending on the use environment. In such a case, there is a risk that water leakage may occur around the water supply hole or the water passage hole, leading to a decrease in the reliability of the humidifier that is the finished product.
[0006]
Furthermore, as described above, since the conventional humidifier is manufactured using an adhesive, once the humidifier is completed as a humidifier, the laminated humidifier is disassembled into individual humidifiers. Even if the individual humidifying functional bodies are disassembled into individual water guide members, ribs, and water supply members, it is difficult to return them to a state in which they can be used again as parts, for example, because the adhesive remains. For this reason, what is determined to be defective by the water leak inspection after being completed as a humidifier can only be disposed of, and this increases costs.
[0007]
The present invention has been made in order to solve the above-described problems, and its purpose is to manufacture a humidifier at a low cost with a small number of man-hours and to meet the demand for multi-model small-volume production. Further, the present invention provides a humidifier that can improve the reliability and can be reused even if it becomes a defective product in the inspection stage, and a ventilator equipped with the humidifier.
[0008]

Further, in the vicinity of the right side surface of the front surface of the water supply unit 2, a cylindrical pipe connection portion 2 b that communicates from the front side to the water tank 2 a and protrudes to the front side is formed.
[0012]
Next, the manufacturing method of the humidifier of the said structure is demonstrated.
(1) Formation process
(1) First method
Porous moisture permeable material or non-porous moisture permeable material (including non-moisture permeable material in the case of the water supply part 2) by the injection molding method or extrusion molding method (hereinafter collectively referred to as a forming material). ) Are melted and injection molded or extruded using a mold to obtain each formed body of the humidifying function part 1 and the water supply part 2, and then the mold is extracted in two directions (in the case of the injection molding method) Or the formed body is taken out from the mold (in the case of extrusion molding).
(2) Second method
After filling the mold with the powder of the forming material, the inside of the mold is heated to a temperature equal to or higher than the melting point of the forming material, and the forming material in the mold is sintered to each of the humidifying function unit 1 and the water supply unit 2. A formed body is obtained.
(3) Third method (hybrid method)
A forming material obtained by dispersing a pore-forming material that is solid at room temperature in a polymer substance is melted at a temperature at which the pore-forming material melts, and injection molding or extrusion molding is performed using a mold, and the humidifying function unit 1 and After obtaining each solid formed body of the water supply unit 2, each solid formed body is washed with a solvent that does not melt the polymer substance but melts the pore forming material, thereby forming pores. For details of the third method, refer to, for example, Japanese Patent Application Laid-Open Nos. 2001-2825 and 2002-194131. The same applies to other embodiments.
(4) Fourth method
About the water supply part 2, the formation body is obtained by the above-mentioned 1st thru | or 3rd method. On the other hand, about the humidification function part 1, after obtaining the formation body of a substantially rectangular parallelepiped shape by the above-mentioned 1st thru | or 3rd method, either the air supply chamber 1a, the water flow chamber 1b, or the method of cutting or the like Formed by.
(2) Coating process
When each formation body of the humidification function part 1 and the water supply part 2 consists of a porous moisture-permeable body, each formation body is immersed in the organic polymer which has water repellency and oil repellency, or the said organic polymer is put on the surface of each formation body The surface of each formed body is coated by spraying.
(3) Joining process
The humidifying function unit 1 and the water supply unit 2 are bonded to each other by applying an adhesive to the bonding surfaces, bonded by fusing the bonding surfaces by heat fusion, or packing on the bonding surfaces as necessary. Use screws or caulking to join.
[0013]
Next, the operation of the humidifier configured as described above will be described. First, a pipe (not shown) is connected to the pipe connection part 2b of the water supply part 2, and water is stored in the water tank 2a and each water flow chamber 1b via the pipe. When the humidification function part 1 consists of a porous moisture-permeable body, water vapor passes through the holes formed in the left and right walls of the water flow chambers 1b of the humidification function part 1 and directly into the adjacent air supply chamber 1a. In the case where the humidifying function unit 1 is made of a nonporous moisture permeable body, water molecules permeate and diffuse into the left and right walls of the water flow chambers 1b of the humidifying function unit 1, and from the wall of the adjacent air supply chamber 1a It becomes steam and enters the air supply chamber 1a. On the other hand, the air of the dry atmosphere supplied from the outside is supplied to each air supply chamber 1a of the humidifying function unit 1 in FIG._ThreeThe back surface 3 of the humidifying function unit 1 enters from each opening formed in_FourIt exits from each opening formed. At this time, as described above, since water vapor enters each air supply chamber 1a from the adjacent water flow chamber 1b, the air in the dry atmosphere is supplied with moisture from the water vapor and is processed into the air in the humidified atmosphere. Being out.
[0014]
Thus, according to the structure of this example, the humidification function part 1 is manufactured only by the injection molding method, the extrusion molding method, the sintering method or the hybrid method, or only these methods and the cutting process. Therefore, since it is not necessary to go through many steps as in the prior art, the reliability of the humidifier can be improved accordingly. In addition, since the shape of the humidifying function unit 1 is determined only by the mold or only by the mold and the cutting shape, even if a design change such as a change in the shape of the humidifier or a large number of models are produced at one time, It is only necessary to exchange or change the die and change the cutting shape, and it is not necessary to reexamine the manufacturing process as in the conventional case. Therefore, it is possible to sufficiently meet the recent demand for multi-model small-volume production. Furthermore, according to the structure of this example, the humidification function part 1 consists of a single formation body, and the adhesive agent whose property is easy to change with temperature, humidity, etc. is not used conventionally. Therefore, water leakage does not occur in the humidifying function unit 1, and the reliability of the humidifier that is a finished product can be improved in this respect as well.
[0015]
Further, according to the configuration of this example, the humidifying function unit 1 and the water supply unit 2 are bonded to each other by applying an adhesive to the bonding surface, or bonded by fusing the bonding surface by thermal fusion. Alternatively, if necessary, the joint surface is inserted with a packing and joined using screws, caulking, or the like. Therefore, when the humidifying function unit 1 and the water supply unit 2 are manufactured using the same material and joined using heat fusion, screws, caulking, or the like, the water leak inspection after completing the humidifier Even if it is determined to be defective, it can be reground and reused as pellets or powder. As a result, the cost of the humidifier can be reduced. On the other hand, when the humidification function part 1 and the water supply part 2 are manufactured using separate materials, the humidification function part 1 and the water supply part 2 are manufactured using the same material and bonded using an adhesive. Even if it is a case, it is possible to inspect only the humidifying function part 1 before joining, to re-grind defective products, and to reuse them as pellets or powders. Also in this case, since the process after the water leakage inspection is only one process of joining the humidifying function unit 1 and the water supply unit 2, the reliability of the finished product is considerably high and the cost can be reduced. .
Further, according to the configuration of this example, when each forming body of the humidifying function unit 1 and the water supply unit 2 is made of a porous moisture permeable body, each forming body is immersed in an organic polymer having water repellency and oil repellency. Alternatively, the surface of each formed body is coated by spraying the organic polymer onto the surface of each formed body. Therefore, since the humidification function part 1 and the water supply part 2 have water repellency and oil repellency, the porous moisture permeable body is hydrophilized by oily components such as cutting oil and organic or inorganic impurities in the water for humidification. Water leakage that occurs can be prevented.

[0023]
Embodiment 3 FIG.
FIG. 7 shows an exploded state of the humidifier according to Embodiment 3 of the present invention, FIG. 8 shows an external configuration of the humidifier, (a) is a front view, and (b) is a front view. A top view, (c) is a bottom view, and (d) is a right side view. 7 and 8, parts corresponding to those in FIGS. 1 and 2 are given the same reference numerals, and descriptions thereof are omitted. In the humidifier shown in FIGS. 7 and 8, in place of the humidifying function unit 1 shown in FIGS. 1 and 2, a humidifying function unit 21 is newly provided, and a cover 23 is newly provided.
[0024]
The humidification function part 21 consists of a nonporous moisture-permeable body which does not permeate | transmit water mentioned above but permeate | transmits water vapor | steam, for example. The humidification function part 21 has a substantially rectangular parallelepiped shape as a whole. The humidifying function unit 21 is provided on the left side 22₁From the vicinity of the right side 22₂Is a substantially rectangular parallelepiped shape at a predetermined interval toward the vicinity of the_ThreeFrom the side to the back 22_FourA plurality of air supply chambers 21a (four in the example of FIGS. 7 and 8) penetrating on the side are formed. Further, the humidifying function unit 21 has a left side surface 22.₁From the vicinity of the right side 22₂Between the air supply chambers 21a adjacent to each other at a predetermined interval and having a substantially rectangular shape and having a bottom surface 22_FiveFrom the side of the upper surface 22₆A plurality (three in the example of FIGS. 7 and 8) of water flow chambers 21b penetrating on the side of the water is formed. The cover 23 is made of, for example, a porous body that transmits air but does not transmit water (hereinafter referred to as “porous air-permeable gas”), and a large number of holes are formed throughout.
[0025]
In the third embodiment, unlike the first and second embodiments described above, the bottom surface 22 of the humidifying function unit 21._FiveFrom the side of the upper surface 22₆A plurality of water flow chambers 21b penetrating to the same side are formed and a cover 23 made of porous gas is provided for the following reason. That is, when water is supplied to the water tank 2a for the first time after installing the humidifier, or when water is supplied to the water tank 2a after maintenance or failure repair, each water flow chamber 21b contains air. When the humidifying function unit 21 is made of a porous moisture permeable body, air is sequentially emitted from a number of holes formed above the water flow chambers 21b as water is stored in the water flow chambers 21b by water supply. As a result, water can be stored in each of the water flow chambers 21b. On the other hand, when the humidification function unit 21 is made of a nonporous moisture permeable body, there is no air escape space in each water flow chamber 21b even if an attempt is made to store water in each water flow chamber 21b by water supply. A so-called “air reservoir” is formed in the upper part of the chamber 21b, so that water cannot be stored in each of the water flow chambers 21b, and the function of the humidifier cannot be fully utilized.
[0026]
In this regard, if the humidifier is a model that supplies water from above the humidifying function unit 21, the air contained in each water flow chamber 21b is pushed out to the water supply side by the pressure of the water supplied. It is also conceivable to exhaust the air contained in each water flow chamber 21b with a pump or the like before water supply. However, since the humidifier is required to have a degree of freedom in its installation direction, depending on the model, it is not possible to supply water from above the humidifying function unit 21, or from the viewpoint of cost etc., the pump is only used to eliminate the above “air pool”. It may not be possible. Therefore, in the third embodiment, the bottom surface 22 of the humidification function unit 21 is used._FiveFrom the side of the upper surface 22₆A plurality of water flow chambers 21b penetrating to the side of the water is formed, and a cover 23 made of porous gas is provided. Thus, as water is stored in each water flow chamber 21b by water supply, air sequentially comes out from the openings formed above each water flow chamber 21b and the numerous holes formed in the cover 23. The above “air pool” is eliminated, water can be stored in the entire water flow chambers 21b, and the function of the humidifier can be fully utilized.
