Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hygroscopic device utilizing the moisture absorption function of a deliquescent hygroscopic composition such as calcium chloride or magnesium chloride. The present invention relates to a hygroscopic device installed in a kitchen cabinet or the like and used to remove moisture in the room.

[Conventional technology]

A conventionally known basic structure of this type of moisture absorber is that a deliquescent hygroscopic agent is contained in a middle container suspended from an upper portion of a container main body,
The moisture absorbent absorbs moisture and reacts, and the deliquescent liquid is dropped from the liquid passage hole at the bottom of the inner container into the storage chamber provided in the lower part of the container main body, and the container main body falls over. At this time, in order to prevent the deliquescent liquid accumulated in the storage chamber from flowing out of the container, a moisture permeable film (a microporous film structure such as fluorine resin is applied to the opening of the container main body, air and water vapor etc. are applied. (A special film that allows the passage of gas molecules but does not allow the passage of water or a liquid such as an aqueous solution of calcium chloride) (see JP-A-61-93 and JP-A-62-179019).

[Problems to be solved by the device]

In the conventional moisture absorber described above, since the structure in which the opening of the container main body is covered with the above-mentioned moisture-permeable film, it is possible to prevent the deliquescent liquid from flowing out of the container, but the moisture-permeable property. Since the film has low air flowability, it has a drawback that the moisture absorption rate is slow.

On the other hand, although an electric (heat pump) dehumidifier is commercially available, this dehumidifier is expensive, but on the other hand, due to its structure,
Not suitable for installation in closets.

The present invention uses the deliquescent hygroscopic agent described above,
It was developed with the intention of eliminating the problems of conventional moisture absorbers in which the opening of the container body is covered with a moisture permeable film. Even if the container falls, the deliquescent liquid stored in the container does not flow out of the container without adopting the structure of covering the main opening, and the electric dehumidifier described above is not affected. However, it is an object of the present invention to provide a hygroscopic device that exhibits a hygroscopic capacity about 10 to 15 times that of a conventional hygroscopic device of this type.

[Means for solving the problem]

In order to achieve the above-mentioned object, in the present invention, a deliquescent hygroscopic agent such as calcium chloride or magnesium chloride is housed and arranged inside a container body having an open upper surface,
An inner lower portion is formed in a storage chamber, a lid is arranged at an opening on an upper surface of the container body so that the inside can be sealed, and an air suction cylinder of a predetermined length that hangs inside the container body on a lower surface of the lid. And a fan capable of rotating in the normal and reverse directions is provided inside, a through hole is provided in a portion of the lid body corresponding to the upper surface of the air intake cylinder, and a fan of the upper edge of the air intake cylinder is provided. A plurality of arc-shaped air discharge passages are formed at portions corresponding to the outer side, and the central portion of the container body is lowered through the through holes in accordance with the rotation direction of the fan, while being expanded to the peripheral portion and raised. An air flow to reach and discharge the air discharge path, or an air flow that passes through the air discharge path and descends along the peripheral edge of the container body, and collects and rises in the center to reach the through hole and is discharged. This air flow comes into contact with the deliquescent hygroscopic agent to absorb moisture. It has a configuration that.

An air discharge tube that surrounds the outside of the air suction tube and hangs down with a predetermined gap is provided on the lower surface of the lid, and the air discharge path is formed by connecting the air suction tube and the air discharge tube. It has a structure provided between them.

[Action]

The hygroscopic device according to the present invention stores a deliquescent hygroscopic agent such as calcium chloride in the container body, and when the fan is rotated with the lid body covered, the air containing moisture in the installation room becomes
Pressurized air is sucked into the container from the air suction cylinder.

Then, the inhaled air is removed by the moisture inside reacts with the deliquescent hygroscopic agent contained in the container, is dried, and is exhausted from the air exhaust passage.

 As a result, the air in the installation room changes to a dry state.

On the other hand, the deliquescent liquid of the deliquescent hygroscopic agent that has reacted with the humidity in the air is dripped and stored in the storage chamber.

Also, by connecting the fan to the battery so as to rotate in the reverse direction, moisture is sucked from the air discharge passage or the air discharge cylinder, and dry air is discharged from the air suction cylinder.

When the air discharge tube is provided outside the air suction tube and the lower edge of the discharge tube is extended to near the center of the container main body, the deliquescent liquid stored in the storage chamber is the air discharge tube. In the case where the water level has reached the level of contacting the lower end of the container, even if the container body tilts or reverses to the posture shown in FIGS. 7 (A) to (D), the stored liquid remains in the container body as shown in FIG. 8 (a). Since it flows to the state of (d), it does not flow out.

The amount of moisture absorbed after the fan stops is about 20 when the fan is rotating.
It is reduced to 1/0.

[Effect of device]

According to the present invention configured as described above, a through hole that is an air intake passage and an air discharge tube are formed in a lid that closes an upper surface opening of a container body, and forced intake and discharge by a fan are performed. Since the deliquescent hygroscopic agent housed and arranged in the container body is made to react with the air flow simultaneously, the moisture absorption in the installation chamber can be performed reliably and effectively.

Moreover, since the fan is installed in the air intake cylinder, the flow velocity in the air intake cylinder is high, and after descending from the center through the air intake cylinder, it spreads outward at the lower inner part of the container body. Air flow that rises and discharges through a plurality of arc-shaped air discharge passages, or descends through a plurality of arc-shaped air discharge passages located at the peripheral edge and gathers inward at the lower inside of the container body. After that, the air flow that rises and is discharged from the air suction cylinder becomes large, and thus a large air flow is generated over the entire inside of the container body.

Therefore, since this air flow comes into contact with the deliquescent hygroscopic agent, the hygroscopic efficiency is very high.
