Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for drying the air inside a closet, shoe rack, etc. by electronically cooling the air.

[Prior Art] Conventionally, in order to dry predetermined spaces such as closets, wardrobes, shoe cabinets, and the underside of washstands, it has been common to use desiccant agents such as quicklime and calcium chloride. This prevents mold from forming on futons, clothing, footwear, etc.

[Problems to be Solved by the Invention] The conventional drying means described above uses a desiccant to dry the air in the predetermined space, 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.

The present invention was made to solve the above problems, and an object of the present invention is to provide an electronic drying device that has high drying ability and can be maintained semi-permanently.

[Means for Solving the Problems] An electronic drying device according to the present invention includes an electronic cooling element, a cooling fin provided on the heat absorption side of the cooling element, and a heat radiation fin provided on the heat radiation side of the cooling element through ventilation holes.

[Function] In this invention, the electronic cooling element and the cooling fins and radiation fins provided thereon are housed in a box body having ventilation holes, and the surface area of the radiation fin is set to 5 times the surface area of the cooling fin.
Since it is set to ~20 times, when the cooling element is energized, a heat absorption effect occurs on the heat absorption side and a heat radiation effect occurs on the heat radiation side, resulting in condensation, frost, or ice formation on the surface of the cooling fins, which causes heat to flow through the ventilation holes. The moisture in the air outside the box body is absorbed with high efficiency9.

The electronic drying device configured as described above is used by being placed in a corner of a closet, clothes drawer, or the like. When the electronic dryer is connected to a power source, an endothermic action occurs on the endothermic side of the cooling element (7), and the cooling fins (8) are cooled, so that water vapor in the air condenses on its surface, and its amount decreases. When the amount increases, water drops form and drip from the tip at the bottom. Cooling fins (8
) The lower end of the fin plate (8a) is inclined downward and the edge is formed into a blade shape, so water droplets easily flow downward.
And easy to drip. This water droplet is absorbed by the cylindrical body (1) of the lid (15).
5b) and is stored in the water storage tank (14).

On the other hand, heat generation occurs on the heat radiation side of the cooling element (7),
This heat is transferred to the radiation fins (10) through the heat transfer body (9). Here, when the blower (5) rotates, the box body (
1) Outside air is sucked in through the mesh (lla) of the filter (11), and the dust-removed air flows from the bottom to the top inside the box (1). The heat transferred to the radiation fins (10) is
Riding the air flow above, it passes through the ventilation hole (4a) and the box body (])
Heat is radiated outside. Heat dissipation fins (10) due to its airflow
The heat is efficiently dissipated, and the amount of heat absorbed from the cooling fins (8) increases, so that the dehumidification capacity increases. Also, air is sucked in from the front of the cooling fin (8) and
Since the cooling fins (10) move toward the radiation fins (10) while contacting the cooling fins (8), more moisture comes into contact with the cooling fins (8), and the amount of dehumidification increases. The amount of dehumidification at this time is the heat radiation fin (10
) and the cooling fins (8), and whether this surface area ratio is large or small, the dehumidifying effect is impaired, and the fourth point is that it is most practical when this surface area ratio is between 5 and 20. This has been confirmed from the experimental results shown in the figure.

As described above, the air outside the box (1) is filtered through the filter (1).
1) and condensation on the cooling fins (8), moisture is removed from the air outside the box (1) and maintained in a dry state. Although details are omitted, when the ambient temperature is low, the cooling fins (8) are controlled to be in a frost or ice state.

Now, during use, water droplets are stored in the water storage tank (14), and the situation can be visually observed from the outside.

Since the water storage tank (14) has a vertically elongated shape, changes in water level appear large and are easy to see. In particular, the inclined surface (14b
) makes it easy to check changes in water level in the early stages of storage.

Most of the opening on the top of the water storage tank (14) is covered with a lid (
15) and only the cylindrical body (15b) is open upward, the amount of water evaporating from the water storage tank (14) is limited, which impedes the dehumidification effect of the cooling element (7). There aren't many. When the water storage capacity in the water storage tank (14) increases and becomes full, the water will flow) - (
18) floats up and engages the lever (16) via the actuator (19).
a) is turned, and the water detection switch (16) is activated to cut off the circuit of the cooling element (7) and prevent the formation of water droplets due to frost formation. At the same time, the 1 alarm (20) rings to notify that the water is full and urges the water to be removed.

To remove water from the water tank (14), press the knob (1
4a) and pull out the water storage tank (14). At this time, the filter (11) rotates toward you. Water storage tank(
14), drain the water inside and store it in the outer frame (2) in the reverse order of the above.

In addition, when the ozone generator (21) is energized, ozone is generated and released outside the box (1), which sterilizes mold, etc. that grows on clothes stored in closets, clothes drawers, etc., and eliminates odors. Prevent occurrence.

[Effects of the Invention] As explained above, in this invention, the electronic cooling element, the cooling fins and radiation fins provided thereon, and the water storage tank are housed in the box, so that heat absorption and heat radiation effects occur in the cooling element. By condensing, frosting, or freezing on the surface of the cooling fins, moisture from the air outside the box is absorbed with high efficiency, and the drying ability can be maintained semi-permanently.
