Title:
WET BALL WICK WATER-SUPPLYING DEVICE
Document Type and Number:
Japanese Patent JP3140709
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent various germs from being reproduced by eliminating a float and hence simplifying a structure.
SOLUTION: Dry-bulb and wet-bulb temperatures t and t' are measured by dry-bulb and wet-bulb temperature sensors 4 and 1, respectively, and the sensors are loaded into a water-supply control part 6 and then amount of wick water consumption is obtained by an expression being stored in advance, and the operation rate of an electromagnetic pump 4 is controlled so that the amount of water where a small amount of surplus water is added can be fed. The surplus water is overflown from the water supply port of a wick pan 3, thus eliminating the need for controlling the water level due to a float. The water level is controlled by changing the amount of water feed according to usage conditions, thus reducing the surplus water, eliminating the need for the collection, and simplifying a device. Since the water supply part of the wick pan is short and, for example, a tank for controlling water level is eliminated, thus reducing the amount of preserved water, reducing the residence time of water, and suppressing the reproduction of various germs.
