Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dehumidifying device. More specifically, the present invention relates to a compact, maintenance-free dehumidifying device that can be used in various types of storages, distribution boards, and the like.

[0002]

[Prior Art]

 Conventionally, various dehumidifiers such as electronic cooling type, refrigerant type, and hygroscopic agent type have been used in various storages and distribution boards. Since it is relatively simple, it is widely used in various fields, and the hygroscopic agents used are classified as those that are disposable, those that require regular regeneration, and those that are maintenance-free.

Of these, the dehumidifying device in which the hygroscopic agent is maintenance-free is generally a fan that blows a hygroscopic agent (a) and air to be dehumidified to the hygroscopic agent (a) as illustrated in FIG. 5, for example. (A) and a heater (c) that regenerates the hygroscopic agent (a) that adsorbs moisture in the air. That is, in such a conventional dehumidifying device, when dehumidifying, the fan (a) introduces moist air from the air supply port (d) and blows it to the moisture absorbent (a) to remove moisture in the air. Is adsorbed on the hygroscopic agent (a) and the dry air is discharged from the exhaust port (e). On the other hand, at the time of regenerating the hygroscopic agent (a), the air heated by the heater (c) is blown to the hygroscopic agent (a) by the fan (a), and the hot air evaporates and dries the moisture of the hygroscopic agent (a). .

With such a mechanism, the maintenance-free dehumidifying device can be used for a long period of time without replacing the dehumidifying agent (a).

[0005]

[Problems to be solved by the device]

 However, in the case of the conventional dehumidifier, as shown in FIG. 5, the hygroscopic agent (A), the fan (A) and the heater (C) are separate bodies and are separately arranged in the case. As a result, the size of the entire device has increased and a large amount of device space has been required. For this reason, for example, a dry dehumidifier (Japanese Patent Laid-Open No. 2-194810) has been proposed in which a fan (a) blades are integrally provided with a hygroscopic agent (a), but in the case of this device, There is a limit to downsizing of the entire device because a space is required for an air duct that communicates with the air supply port (d) and / or the exhaust port (e).

The present invention has been made in view of the above circumstances, and is an improved maintenance-free dehumidifying device that solves the drawbacks of the conventional dehumidifying device, is small, and has excellent dehumidifying performance. Is intended to provide.

[0007]

[Means for Solving the Problems]

 This invention solves the above-mentioned problems by providing a hygroscopic agent filled as a honeycomb structure in the heat transfer body frame, a heater arranged in the center of the hygroscopic agent, and a fan for supplying and exhausting the hygroscopic agent. To provide a dehumidifying device characterized by being provided.

[0008]

[Action]

 In the dehumidifying device of the present invention, the heater is arranged in the center of the heat transfer body frame filled with the hygroscopic agent, so that the entire device can be downsized. In addition, when the hygroscopic agent is regenerated, the heater directly heats the hygroscopic agent, so that the regeneration efficiency is good.

Further, since the hygroscopic agent is filled as a honeycomb structure, its dehumidifying effect is also extremely excellent.

【Example】

 Hereinafter, embodiments will be shown with reference to the accompanying drawings to explain the present invention in more detail. FIG. 1 is a perspective view illustrating a hygroscopic agent and a heater that can be used in the dehumidifying device of the present invention.

For example, as shown in FIG. 1, the moisture absorbent (1) of the present invention is used as a honeycomb structure in the space divided by the heat equalizing plate (3) in the heat transfer frame (2). It is filled. A space (4) is formed by the heat equalizing plate (3) in the center of the heat transfer frame (2), and a cylindrical electrothermal heater (5) is inserted into the space (4) and arranged. It is designed to be integrated.

As the hygroscopic agent (1), those which are excellent in water absorption and water discharge are preferable, and for example, polymer materials such as silica gel can be exemplified as preferable ones. Further, the heat transfer body frame (2) and the heat equalizing plate (3) can be made of, for example, a metal plate material such as a stainless plate. The size and shape of the heat transfer member frame (2) can be appropriately set, and can be, for example, a thin shape as illustrated in FIG.

FIG. 3 is a cutaway perspective view of an essential part showing an embodiment of the dehumidifying device of the present invention. For example, in the case of the dehumidifying device (6) illustrated in FIG. 3, the housing (7), which is the body of the dehumidifying device (6), is filled with the hygroscopic agent (1) in a honeycomb shape, and the heater (5) is provided at the center thereof. ) And a sirocco fan (8) for blowing air to the hygroscopic agent (1).

Further, the housing (7) has a first air supply port (9) and a second air supply port (10) on the upper and lower side surfaces of the sirocco fan (8), respectively, behind the hygroscopic agent (1). A first exhaust port (11) and a second exhaust port (12) are provided on the end face and the side face located, respectively. FIG. 4 is a schematic plan view showing an installation example of the dehumidifying device (6).

For example, when the dehumidifying device (6) of the present invention is installed inside the storage (13) as illustrated in FIG. 4, at the time of dehumidification, the second air supply port (10) and the second air exhaust port The sirocco fan (8) is operated with the heater (5) stopped while the heater (5) is closed, and the humid air in the storage (13) is introduced from the opened first air supply port (9). Then, this is blown to the hygroscopic agent (1) to remove the moisture by the hygroscopic agent (1), and then discharged as dry air from the first exhaust port (11) into the storage (12) ( (Solid arrow in the figure).

On the other hand, when regenerating the hygroscopic agent that has adsorbed water in this way, the sirocco fan (8) and the heater are closed with the first air supply port (9) and the first exhaust port (11) closed. When (5) is activated, external air is introduced from the opened second air supply port (10), and this air is blown to the hygroscopic agent (1), and the second air is discharged together with the water vaporized by the heat of the heater (5). The gas is discharged from the exhaust port (12) to the outside (broken line arrow in the figure).

It should be noted that the heater (5) and the sirocco fan (8) are activated and deactivated, or the air supply ports (9) (10) and Each of the exhaust ports (11) and (12) can be opened and closed manually by an external switch. Alternatively, the series of operations can be automatically performed by an input electric control circuit or the like.

Of course, the present invention is not limited to the above examples, and it goes without saying that various aspects are possible in details.
