3) The υ1 and water openings (1 and 0) formed on the bottom plate are fan guards.

and an electronic cooling element (4) and both fans (9),
(When the dehumidifying operation is started by driving II, the thermal conductor (
5), the temperature of the cooling fins (6) decreases, and the temperature of the radiation fins (7) increases, causing the intake fan (9
) The external humid air taken in by the cooling fins (6)
The water vapor contained in the humid air condenses into water, and the water is discharged from the drain port 01), and the air from which moisture has been removed becomes dry air.
10 is guided to the exhaust port (2) side, heated by the radiation fins (7), and discharged to the outside from the exhaust port (2).

Here, the intake fan (9) cools the outside air with cooling fins (6
) to promote the condensation of water vapor, and the exhaust fan 01 also forcibly sucks in air near the radiation fins (7) to promote heat radiation and enhance the dehumidification effect. . In addition, the heat conductor (5) not only prevents freezing with a built-in switch, but also increases the dimension between both fins + a) and (7) by the thickness of the heat conductor (5) itself.
This has the effect of making the heat insulation between the two fins +6+ and (7) more reliable.

However, according to the conventional dehumidifier, the intake fan (9
) and the heat dissipation side by the exhaust fan 00, two fans (9) are required.
, QO is not required, power consumption is large, operating cost increases, and both fans (9).
Since the number of moving parts increases due to +10, there is a disadvantage that the failure rate increases.

This invention was made with the above points in mind,
A cylindrical vertically outer case and a cylindrical vertically inner case whose upper part is made of a metal material and whose lower part is made of a heat insulating material are provided in a double cylinder structure, and the lower part of the inner case is connected to the outer case. A dehumidifying passage and a cooling passage are formed inside the inner case and around the entire circumference between the two canes, respectively, and a vertical heat conductive plate is provided inside the inner case, and a heat conductive plate is provided in the upper and outer sides of the heat conductive plate. The side surface is bonded to the metal material of the inner case, and the heat generating surface of the electronic cooling element utilizing the Beltier effect is bonded to the lower inner surface of the heat conductive plate, and the cold cutting surface of the electronic cooling element and the mI Cooling fins and radiation fins are respectively bonded to the upper inner surface of the heat conduction plate, and a fan is provided at the upper part of the outer case 7 to form an air flow from bottom to top in both the passages. The present invention provides a dehumidifying device.

Therefore, according to the dehumidifying device of the present invention, the outer case 7
The double cylinder structure of the inner case and the inner case allows a dehumidifying passage for dehumidified air and a cooling passage for cooling air to be formed. Heat is transferred to the metal material of the inner case, and nuclear heat can be dissipated to the air in the dehumidifying passage and the cooling passage, so the heat dissipation surface area is large and the heat dissipation effect can be enhanced.
Therefore, the cooling effect of the cooling fins can be enhanced and the dehumidification performance can be improved.Moreover, the lower part of the inner case is led out from the lower end of the outer case, and the lower end opening of the dehumidifying passage is closer to the lower end opening of the cooling passage. Because it is located at the bottom, there is no need to worry about the air flowing into the dehumidifying passage being sucked into the cooling passage, and air from different spaces flows into both passages, increasing the amount of air flowing into both passages. This allows the dehumidification performance to be further improved.

In addition, one fan blows air to the cold cutting surface.

In other words, it is possible to blow dehumidifying air and blow air to heat-generating surfaces, that is, blow cooling air, so there is no need to use two fans as in the past, reducing operating costs and reducing malfunctions. The ratio can also be reduced.
