Description

TECHNICAL FIELD The present invention relates to an air conditioner that obtains humidified air or cold air by rotating a belt-shaped filter having a lower part immersed in a water tank and ventilating the belt-shaped filter.

(B) Prior Art Air-conditioning described in the specification and drawings attached to the application of Japanese Patent Application No. 63-69149 (filed on March 23, 1988) filed by the applicant as a technology prior to the present invention. There is an opportunity.
The air conditioner exhausts the air in the frame from the outlet to make the inside of the frame a negative pressure, and the pressure difference between the outside and the inside of the frame sucks in through the intake port to ventilate the belt filter. Therefore, the inside of the frame has a higher humidity and a lower temperature than the outside of the frame due to vaporization due to passing through the belt-shaped filter. If this air invades various parts inside the frame, especially the electrical component parts, there is a problem with humidity resistance and electrical insulation, so the electrical component was covered with a cover to prevent the air from entering.

However, when covering the electrical equipment with the cover, it is not completely sealed, so air with high humidity enters the space inside the cover,
In addition, the temperature of the inner space of the cover is raised by the electric component, and the outside of the cover is cooled, so that dew condensation may occur on the inner surface of the cover. Further, if the cover is completely covered with the cover, the temperature inside the cover may rise and the electrical components (semiconductor circuit components) may be thermally destroyed.

(C) Problem to be Solved by the Invention An object of the present invention is to provide a cold air fan capable of smoothly increasing the temperature of an electric component part and performing a wiring process.

(D) Means for providing an object of the invention The present invention relates to a frame in which an inlet and an outlet are formed, and a blower in which the outlet side is connected to the outlet and the suction side is located in the frame body space and is installed in the frame body. A device and a water tank arranged in the lower part of the frame,
An electrical component including a switch for controlling the blower and the drive motor, the lower part of which is soaked in water in a water tank, arranged so as to cover the intake port, and provided with a ventilation hydrous belt filter which is rotated by the drive motor. The object is to solve the problem by a means of covering the electric component with an electric component cover body having an electric hole and a cord storage box portion for accommodating and holding the wiring connection portion.

Further, the present invention, a box-shaped frame body having an intake port formed on the rear wall and an outlet port formed on the front wall, and a water tank disposed in the lower portion of the frame body,
Cover the intake port, immerse the lower part in the water in the water tank, connect the ventilated hydrous belt filter that is rotated by the drive motor, the outlet side to the outlet port, and position the intake side inside the frame body space. An air blower installed inside the body and an electrical board that is fixed to a boss that projects from the inside of the frame and that includes a switch that controls the blower and the drive motor; and a ventilation section that covers the electrical board and the inside of the frame. The problem is solved by a means for forming an air conditioner with an electric component cover body in which a vent hole is formed in the rear wall portion and a cord storage box portion for storing the intermediate wiring connection portion is formed.

(E) Operation In the present invention, air is sucked in from the air inlet by the air blower so as to make the inside of the frame negative pressure, and the electric component cover body is positioned in the flow, and the air inside the electric component cover body is passed through the ventilation hole. By constantly flowing, even if high-humidity air flows, the insulating property is not bad and dew condensation does not occur.

Also, when the air conditioner is stopped, the heat generated by the electrical components has stopped the flow of air inside the frame, and the humidity has dropped due to the rise in the air temperature inside the electrical component cover, resulting in poor electrical insulation of the electrical components due to high humidity. Is also prevented.

(F) Example The present invention is embodied in a cold air fan 1 as an air conditioner that obtains cold air by utilizing vaporization and latent heat of water, and will be described in detail with reference to the drawings.

And a lid 6. The lid 6 has an intake port 8 covered with the belt-shaped filter 5. The main frame body 2 and the lid body 6 form a frame body of the cold air fan 1, and a ventilation path that passes through the belt-shaped filter 5 from the intake port 8 to the outlet port 7 is formed in the frame body.

The cold air fan 1 rotates the belt-shaped filter 5,
The part of the belt-shaped filter 5 immersed in the water W in the water tank 4 moves from the bottom to the top and from the top to the bottom in the ventilation path, and the belt-shaped filter 5 always containing water is located in the ventilation path. Air is passed through the belt-shaped filter 5 by blowing air, and cool air is obtained by utilizing latent heat of vaporization of water. This cold air is cold air with high humidity. When the belt-shaped filter 5 is stopped, water is not supplied to the belt-shaped filter 5, and when the belt-shaped filter 5 is dried, cooling due to the latent heat of vaporization of water is lost and air is simply blown (no temperature change).

The guide rod 11 may be a driven roller that rotates, or the sliding surface of the belt-shaped filter 5 may be a fixed rod that is fixed to the stage. A drive roller 13, which is driven to rotate by a drive motor 12, is pivotally supported between the upper ends of the support wall plates 9. A part of the belt-shaped filter 5 can be separated by the joining means 14, so that the belt-shaped filter 5 can be easily installed and removed between the drive roller 13 and the guide rod 11.
