Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electronic cooling dehumidifier operation control device for efficiently controlling the operation of an electronic cooling dehumidifier that cools and dehumidifies the inside of a box by an electronic cooling element.

[Conventional technology]

In general, in closed switchboards and various control equipment, in order to ensure high reliability of internal equipment, high temperature inside the box is prevented and dew condensation is prevented, and an electronic cooling dehumidifier using an electronic cooling element utilizing the Peltier effect is used. It is used.

In this electronic cooling dehumidifier, as shown in FIG. 3, an electronic cooling element (3) is arranged in a through hole formed in a side wall of a box (1) via a heat insulating material (2), and an element (3 ) The heat dissipating fins (4) which are in contact with the heat generating surface are arranged outside the box body (1), and the heat absorbing fins (5) which are in contact with the heat absorbing surface of the element (3) are arranged inside the box body (1). The peripheral side of the endothermic fins (5) is covered with a cover (6).

An intake port (7) is formed on the upper surface of the cover (6),
An exhaust port (8) is formed on the lower surface, and a water receiver (10) having a drain port (9) communicating with the outside of the box (1) is provided below the exhaust port (8).

Furthermore, above the heat absorbing fins (5) in the cover (6),
An intake fan (11) for sucking the air in the box (1) into the cover (6) is provided.

When the electronic cooling element (3) is energized and driven, the temperature of the endothermic fin (5) decreases due to the temperature decrease of the heat absorbing surface of the element (3), and the heat radiating fin due to the temperature increase of the heat generating surface of the element (3). The temperature of (4) rises and the heat of the radiating fins (4) is released to the outside, while the hot and humid air in the box (1) is sucked from the intake port (7) by driving the fan (11). The air is blown onto the endothermic fins (5), the air comes into contact with the endothermic fins (5) to lower the temperature, and the moisture in the air is condensed on the endothermic fins (5).

Then, the air that has become low in temperature and dried through the heat-absorbing fins (5) is exhausted from the exhaust port (8), and the dehumidified water that has condensed on the heat-absorbing fins (5) falls into the water receiver (10) and is discharged. The water is drained from the mouth (9) to the outside of the box (1).

Conventionally, the operation of the electronic cooling dehumidifier has been performed in continuous operation, operation of manually turning on and off, and operation of turning on when the temperature is equal to or higher than a specified temperature.

[Problems to be solved by the device]

In the case of the conventional continuous operation, there is a problem that it is an obstacle to energy saving and prolonging the life of the electronic cooling / dehumidifier.

Further, in the case of the operation that is manually turned on and off, there are problems that labor is reduced and reliability is impaired.

Further, in the case of an operation that is turned on when the temperature is equal to or higher than a specified temperature, high humidity and dew condensation cannot be prevented, which causes a problem of humidity failure.

The present invention has been made in consideration of the above points, and an object of the present invention is to provide an operation control device for preventing high humidity, preventing dew condensation and preventing high temperature, and further energy saving, labor saving, long life and high reliability.

A water receiver for receiving dehumidified water that has condensed on the heat absorbing fins, a drain port formed in the water receiver for discharging the dehumidified water to the outside of the box body, and an air inside the box body provided in the cover. An intake fan for inhaling the inside of the cover, a switch provided in the energization path of the electronic cooling element, a humidity sensor for detecting the humidity inside the box body, and a temperature sensor for detecting the temperature inside the box body, When the humidity detection value of the humidity sensor is above the specified humidity And an operation control unit that turns on the switch when the detected humidity value is lower than the specified humidity and the detected temperature value of the temperature sensor is equal to or higher than the specified temperature, and turns off the switch at other times.
