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] The 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 radiation fin and a cooling fin provided on the heat radiation side. A water storage tank provided below and storing water dripping from the cooling fins is housed in a box body having ventilation holes, and the water storage tank is provided with:
A cylindrical body whose upper surface opens at the upper surface of this water storage tank and whose lower end opens near the bottom of the water storage tank is provided, and the spatial area of the cross section of this cylinder is set to 1/10 of the spatial area of the cross section of the water storage tank.
The settings are as follows.

[Function] In this invention, since the electronic cooling element, the cooling fins and heat radiation fins provided thereon, and the water storage tank are housed, when the cooling element is energized, the heat absorption effect is exerted on the heat absorption side, and the heat absorption effect is exerted on the heat radiation side. A heat dissipation effect occurs, and the surface of the cooling fins freezes, frosts, or freezes, and moisture from the air outside the box body is absorbed through the ventilation holes, and this moisture is stored in the water storage tank. . In addition, the water storage tank was equipped with a cylindrical body that opened near the top and bottom, and the cross-sectional area of this cylinder was set to 1/10 or less of the cross-sectional area of the water storage tank, so the amount of evaporation of the stored water into the box body was suppressed.

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. These water droplets are 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 (lO) 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
The box (1) rides on the airflow and passes through the ventilation hole (4a).
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 heat dissipating fins (lO) while contacting the cooling fins (8), more moisture comes into contact with the cooling fins (8), and the amount of dehumidification increases.

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 will be omitted, when the ambient temperature is low, the cooling fins (8) are controlled to be in a frosted or frozen 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.

The amount of water evaporation in the water storage tank (14) is proportional to the area of water, and it is desirable that S1/So be small in order to limit the amount of water evaporation. However, if Sl is too small, dust clogging is likely to occur, making it impractical. In this embodiment, most of the opening on the top surface of the water storage tank (14) is
Since it is closed by the lid (15) and only the cylindrical body (15b) is open upward, when the water surface of the stored water reaches the lower end of the cylindrical body (14b), S/S is 1 /
10 or less, the amount of water evaporated from the water storage tank (14) is suppressed, and the dehumidification effect of the cooling element (7) is rarely hindered. When the amount of water stored in the water storage tank (14) increases and becomes full, the water floats (18).
) floats up and activates the lever (16a) via the actuator (19).
The full water detection switch (16) is activated to cut off the circuit of the cooling element (7) and prevent water droplets from forming due to dew condensation. At the same time, the alarm (20) sounds 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.

FIG. 5 shows a water storage tank (14
) is a vertical cross-sectional view of the portion, in which a recess (14d) is provided at the bottom of the water storage tank (14), and the lower end of the cylindrical body (15b) is opened in this portion. That is, since the space area of the cross section of the recess (14d) is smaller than the space area of the cross section of the water storage tank (14), the water surface of the water stored here will quickly reach the surface of the cylinder (15b). reached the bottom end.

This means that the speed <S, /S, can be limited to 1/10 or less.

[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. When the surface of the cooling fins forms dew, frost, or ice, moisture from the air outside the box is absorbed, and the drying ability can be maintained semi-permanently. In addition, the water storage tank is equipped with a cylindrical body that opens near the top and bottom, and the cross-sectional area of this cylinder is set to 1/10 or less of the cross-sectional area of the water storage tank, so that the amount of evaporation of the stored water into the box body is reduced. This has the effect of reducing interference with the dehumidification effect of the cooling element.
