Abstract

PURPOSE:To prevent the lowering of drying capacity by forming the surface provided with a suction port or a diffuser of a box body as an inclined surface. CONSTITUTION:The air outside a box body 1 is sucked from the meshes 11a of a filter 11 and the air from which dust is removed flows through the box body 1 from below to above. The heat transferred to a radiation fin 10 passes through a diffuser 4a while it is carried on an air stream to be discharged out of the box body 1. Air is sucked from the front surface of a cooling fin 8 and moves toward the radiation fin 10 while coming into contact with the cooling fin 8 and the contact of humidity with the cooling fin 8 increases. The upper surface 4A of the box body 1 is formed as an inclined surface and a gap is generated without closing the diffuser 4a. By this constitution, dehumidifying capacity is not impaired.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention can be used to cool airtight boxes, closets, lower chambers, etc. by electronically cooling them to cause dew, frost, or ice formation. This relates to a device that dries the air inside a shoe cabinet or the like.

[Prior Art] Conventionally, in order to dry predetermined spaces such as closets, wardrobes, shoe racks, 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] In the conventional drying means as described above, since a desiccant is used to dry the air in the predetermined space, there is a limit to the drying capacity, and the drying capacity is reduced. There is a problem in that the desiccant must be replaced with a new one again and again.

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 first aspect of the present invention includes an electronic cooling element, cooling fins provided on the heat absorption side of the cooling element, and heat radiation fins provided on the heat radiation side of the cooling element. The fins are housed in a box body having an air intake port and an air outlet, and the surface of the box body provided with the air intake port or the air outlet is formed into an inclined surface.

In a second aspect of the present invention, a protrusion protruding outward is provided near the suction port or the blowout port.

Further, the third invention of the present invention is provided with a net-like body surrounding the front surface of the suction port or the air outlet. The provided cooling fins and radiation fins are housed in a box body that has an air inlet and an air outlet, so when the cooling element is energized, heat absorption occurs on the heat absorption side and heat radiation effect occurs on the heat radiation side. When dew, frost, or ice forms on the surface of the box, moisture in the space outside the box is absorbed through the outlet.

Furthermore, since the box surface on which the suction port or the blowout port is provided is formed as an inclined surface, the suction port or the blowout port will not be blocked even if it is covered with clothes or the like in the storage.

In addition, in the second aspect of the present invention, a protrusion is provided near the suction or outlet, and in the third invention, the front surface of the inlet or outlet is surrounded by a net-like body, so that the clothes in the storage can be removed easily. The inlet or outlet will not be blocked even if it is covered with

The electronic drying device constructed as described above is used by being placed in a corner of a closet, wardrobe, etc.

When the electronic drying device 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 increases. When the amount increases, it becomes water droplets. Drip from the bottom tip. Since the fin plate (8a) of the cooling fin (8) has a downwardly inclined lower end and a blade-shaped edge, water droplets easily flow downward and drip. This water droplet is covered with a lid (
15) and is stored in the water storage tank (14) through the cylindrical body (15b).

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). At this time, the holder (9) is attached to the cooling fin (8).
Since the heat dissipation fins (10) are thermally insulated, heat loss is small. 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 above air flow, it passes through the outlet (4a) and returns to the box (1).
Heat is radiated outside. Heat dissipation fins (10) due to its airflow
The heat dissipation is performed efficiently, and the amount of heat absorbed from the cooling fins (8) increases, so that the dehumidification capacity increases. Also, the 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).
The air outside the box body (1) is dehumidified by being sucked in through the cooling fins (8) and condensed by the cooling fins (8).
/tgJ! The state is maintained. At this time, the top surface (4A)
Since the suction port (4a) is an inclined surface, even if it is covered with clothes or the like in the storage, the suction port (4a) will not be blocked and a slight gap will be created. Therefore, the dehumidification function is not impaired. Although the details will be omitted, when the ambient temperature is low, the cooling fins (8) are controlled to be in a frost or freezing state. Now, during use, water droplets are stored in the water storage tank (14), but most of the opening on the top surface of the water storage tank (14) is closed by the lid (15), and the cylindrical body (15b)
Since only the part with is open upward, the water storage tank (1
The amount of water evaporated from the cooling element (7) is limited, and the dehumidification effect of the cooling element (7) is rarely affected. Water storage tank(
When the amount of water stored in the tank (l4) increases and becomes full, the float (18) floats up due to the water, rotates the lever (16a) via the actuator (19), and activates the full water detection switch (l4).
6) is activated to cut off the circuit of the cooling element (7) and prevent water droplets from forming due to 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 storage tank (14), use the knob (1
4a) and pull out the water tank (l4). At this time, the filter (11) rotates toward you. Water storage tank(
