Abstract
Provided is a water filtering device for a humidifier capable of increasing the filling amount of an ion exchange resin by including a separate inner cylinder having upper and lower diameters that are different from each other, increasing adsorption and removal efficiency of mineral components contained in water by taking a long ionic bonding time between the water and the ion exchange resin, and effectively preventing scales of the mineral components from being extracted by heating a heater to prevent malfunction of the heater or pipes.
Claims25
A water filtering device comprising:
- a case having an water inlet port and a discharge port;
- and
- a cylinder disposed in the case, and providing a space for filling an ion exchange resin so that water entering through the water inlet port is ion-bonded and discharged through the discharge port.
A water filtering device comprising:
- a case having an upper opening, a water inlet port, and a discharge port;
- an upper cap fitted in the upper opening of the case;
- a partitioned cylinder incorporated in one body with the case to provide an outer space for filling an ion exchange resin;
- and
- an inner cylinder detachably fitted in the partitioned cylinder to provide an inner space for filling the ion exchange resin.
