Description

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

[Conventional technology]

Fig. 2 is a perspective view of a conventional natural evaporation humidifier, Fig. 8 is a configuration diagram of a general hollow porous member that constitutes the humidifier shown in Fig. 2, and Fig. 4 is the ff of Fig. 8. FIG. 3 is a cross-sectional view of the cross section at -IV as seen in the direction of the arrow.

(1) is a hollow porous sheet made of a hydrophobic polymer material such as polyethylene, polypropylene, polystyrene, or fluororesin (2), which is formed into a rectangular shape by overlapping the sheets and gluing or heat-sealing the ends. It is a member, and both ends (1
A) and (1b) are provided with a water supply port (3) and a drain port (4) that communicate with the hollow portion (IC).

The sheet (2) is a porous material made from a hydrophobic polymer material, which allows water vapor (gaseous water molecules) to pass through freely, but does not allow liquid water (liquid water molecules) to pass through at all. Therefore, countless micropores with a diameter of 10 μm or less are provided. (5) is a wave shape that is rolled up along the hollow porous member (1) so that when the hollow porous member (1) is rolled up, a ventilation path can be formed between the stacked hollow porous members (1). This is a film-like spacing plate composed of:

The humidifier configured as described above is housed in a casing (7) and attached to the outlet of dry air from an air conditioner or heater, and the water supply port (3) of the hollow porous member (1) is connected to a water supply device. By supplying water into the hollow part of the member (1), only water vapor flows into the sheet (2) of the hollow porous member (1).
) and is released into the ventilation duct, humidifying the dry air.

The drain port (4) is kept closed during humidification and is used to drain water when not in use for a long period of time.

[Problem that the invention seeks to solve]

In the conventional humidifier as described above, the hollow porous member (1) and the spacer plate (5) are wrapped around each other to create a circular shape. When the casing is made into a rectangular shape to match the heat exchanger, the casing becomes square and the area ratio of the area where the hollow porous member (1) does not exist in 4W4 is approximately 21.
．． 5%, the effective humidifying area obtained from the same space was small and the humidifying capacity was low. Furthermore, most of the mounting parts for air conditioners and heaters are rectangular like heat exchangers, so if you install multiple humidifiers housed in square casings in order to obtain the specified amount of humidification, the water supply Since the port (3) and the water distribution port (4) must be connected to the water supply device and the distribution channel (not shown), respectively, the time required for the water supply and distribution piping work is large, the manufacturing cost is high, and the piping connection is difficult. Since there are many locations, there is a problem in that the reliability of watertightness decreases accordingly. In view of this problem, the present invention involves a hollow porous member (1) and a spacer plate (5), and produces a humidifier with a cross-sectional shape approximating the shape of its attachment part. The purpose is to improve humidification capacity by reducing the space where the elastic member (1) does not exist, reduce the number of connection points for water supply and drainage piping, lower manufacturing costs, and further improve watertight reliability. be.

[Means to solve the problem]

A humidifier according to the present invention includes a rectangular hollow porous member having a water supply port at one end and made of a hydrophobic polymer material, and an interval having a wavy cross-sectional shape when overlapped with the hollow porous member. The humidifier is constructed by forming a ventilation passage between the overlapping hollow porous members by wrapping the plates around a prismatic core serving as a core material.

[Effect].

In this invention, a humidifier is constructed by overlapping a hollow porous member with a wave-shaped spacing material and wrapping it around the prismatic material from the other part having the water supply port or the other end with the prismatic material as the core material. Therefore, by making the core material a prismatic material with an arbitrary shape, the humidifier can be installed with a cross-sectional shape that is very close to the shape of the humidifier, and the humidifier can be installed with an effective humidifier for the area. By increasing the area ratio, it is possible to improve the humidifying ability.

〔Example〕

FIG. 1 is a block diagram of a humidifier showing an embodiment of the present invention. (υ to (5) indicate parts that are exactly the same as or correspond to the conventional humidifier shown in FIG. 2.

(8) is a square prism core material, in which the hollow porous member (1) and the spacing plate (5) are overlapped, and the water inlet (3) or drain port (4) of the hollow porous member (1) is connected. The core material (8) is wound around the core material (8) from the end (1a) or (lb) of the wire along the core material (8).

Since the humidifier configured as above is rolled up and has a square shape, there are no hollow porous members (1) at the four corners even when it is installed in a square casing when incorporated into an air conditioner or heater. Almost no part occurs,
Although the central core material (8) is the part where the hollow porous member (1) does not exist, this area is also very small compared to the conventional one. Further, since the shape of the roll is proportional to the aspect ratio of the core material (8), by determining the aspect ratio of the core material (8) according to the dimensional ratio of the attachment part of the air conditioner or heater, a humidifier of desired size can be obtained. In addition, if the air conditioner or heater to which the humidifier is attached has a triangular shape,
If the core material is a triangular prism, the same effect as in the above embodiment can be obtained.

The installation depends on the shape of the part.If a prismatic column with a cross-sectional shape similar to the part shape is used as the core material, the effective humidification area ratio occupied by the hollow porous member (1) will increase when installed. The same effect as in the example can be obtained.

〔Effect of the invention〕

As explained above, the present invention includes a rectangular hollow porous member having a water supply port at one end and made of a hydrophobic polymer material, and a cross-sectional shape overlapped with the hollow porous member having a corrugated shape. The humidifier was constructed by wrapping the spacing plates around a prismatic core material to form a ventilation path between the stacked mud hollow members.The humidifier can be installed by changing the shape of the core material as appropriate. The cross-sectional shape of the humidifier can be made very similar to the shape of the hollow porous member, and the effective humidifying area ratio occupied by the hollow porous member becomes large, which has the effect of improving the humidifying ability.
