Seals 4, 5 are adhered closely with each other thereby and the inner part of box body 1 is insulated from the outside. When a plug 31 is connected with an electric power source, an electric power source element lamp 28 is lighted, and AC voltage is rectified by a rectifying element 34, and the DC voltage is supplied to an electromagnet 21 and a cooling element 8. A movable bar 19 is attracted by energizing the electromagnet 21, and the partition door 15 is turned making a hinge 16 as the center to communicate the receiving chamber 1a with the cooling chamber 14. Cooling fins 12 are cooled by energizing the cooling element 8, and the moisture in the air is dewed on the surface of the fins. Thus, the air in the receiving chamber 1a is dehumidified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for drying the air inside a box by electronically cooling the air to form dew, frost, or ice.

[Conventional technology] Conventionally, in order to protect food, clothing, precision equipment, etc. from moisture, a desiccant such as quicklime or silica gel was packed in a breathable sheet in the container in which these items were stored. It is normal to put it in. This prevents deterioration of food, mold on clothing, and functional deterioration of precision equipment.

[Problems to be Solved by the Invention] The conventional drying means described above uses a desiccant to dry the air inside the container, so there is a limit to the drying capacity, and drying with reduced capacity There is a problem in that the agent must be replaced again and again with a new one.

Dry storage of articles is carried out as follows.

First, open the door (2) by rotating it downward and place the item in the box (1).
) in the storage room (1a). Then, the door (2) is rotated upward and closed, and is latched to the box body (1) by the stopper (6). Since the seals (4) and (5) are now in close contact with each other, ventilation inside and outside of the box body (1) is prevented.

Next, when the plug (31) is connected to the power source, the power source element light (28) lights up. In addition, the alternating current voltage is supplied by a transformer (33
), rectified by the rectifying element (34), and smoothed by the smoothing capacitor (35).
) and the cooling element (8). By energizing the electromagnet (21), the movable rod (19) is attracted, and the partition door (15)
rotates around the hinge (l6) and opens, opening the storage compartment (
1a) and the cooling chamber (14) communicate. On the other hand, the cooling element (8
), an endothermic action occurs on its endothermic side (8a) and the cooling fins (12) are cooled, so water vapor in the air condenses on its surface, and when the amount increases, it becomes water droplets. Drip from the bottom tip. This water droplet is placed in the water socket (
22), but because there is a spherical float (23), the water is stored in the large diameter part of the water socket (22). When this amount of stored water increases, buoyancy will eventually act on the float (23) and the float (23) will float up. This creates a gap between the float (23) and the water receptacle (22), so water is discharged downward and stored in the water receptacle (25).

When water is discharged from the water socket (22), the float (23)
) is lowered and the gap is closed again to prevent external moisture from flowing back into the box (1). In addition, since the lower end of the water socket (13) is tapered, drainage is good. Although the water stored in the water tray (22) naturally evaporates, the water can also be discarded by pulling out the water tray (25) to the outside at a suitable time.

On the other hand, heat generation occurs on the heat dissipation side (8b) of the cooling element (8), and this heat is transferred to the heat dissipation fins (work 1) through the heat transfer body (9), where it is dissipated into the air.

As described above, moisture is removed from the air in the storage chamber (1a) by condensation on the cooling fins (12),
kept dry.

In the embodiment, the cooling fins (12) are used to cause dew condensation, but the cooling fins (12) are cooled to below 0°C to form frost or ice on the surface of the cooling fins (12), and then the cooling is performed. By stopping the power supply to the element (8), frost or ice can be melted and water can be dripped. At this time, the electromagnet (21) is de-energized, the partition door (l5) is moved eight times in the opposite direction by the force of the push spring (20), and the storage room (
1a) and the cooling chamber (14) are isolated. This prevents moisture that evaporates when the frost or ice on the cooling fins (12) melts from entering the storage chamber (la).

[Effect of the invention] As explained above, in this invention, a storage chamber and a cooling chamber are provided in the box body, cooling fins are fixed to the heat absorption side of the electronic cooling element and stored in the cooling chamber, and radiation fins are fixed to the heat radiation side of the electronic cooling element. In addition, a partition door was installed to communicate and cut off the storage room and the cooling room, and the partition door opened when the cooling element was energized and closed when the power was cut off, so that frost generated on the cooling fins or When the ice melts due to a power cut to the cooling element, water that evaporates from the ice is prevented from entering the storage chamber, making it possible to configure a drying device that maintains its drying ability semi-permanently.
This has the effect of improving the moisture absorption performance of the cooling fins.
