BACKGROUND
Field
[0001] The present disclosure relates to a humidifier, and more particularly, to a humidifier
that supplies clean humidified air.
Related Art
[0002] A humidifier is an appliance that supplies moisture-containing air within a room.
The humidifier is equipped with a water reservoir for storing water, and is classified
as ultrasonic humidifier, heated humidifier, natural evaporative humidifier, or hybrid
humidifier depending on the method of humidification.
[0003] Ultrasonic humidifiers are equipped with a vibrator to create vibrations from ultrasonic
waves, and convert water into fine particles using the vibrations from the vibrator
and spray them.
[0004] Ultrasonic humidifiers have advantages such as converting the water stored in the
water reservoir into fine particles and spraying large amounts of mist.
[0005] However, conventional humidifiers are problematic in that the device may have a poor
state of cleanliness because of the stagnant water in the device. As such, air sprayed
from the device can be highly contaminated.
[0006] Another problem with conventional humidifiers is that blown air containing fine dust
or the like may cause degradation in the cleanliness of humidified air sprayed from
them. The fine dust contained in the blown air is deposited in water droplets, thus
leading to high contamination of the humidified air.
[0007] KR 10-2022-0105488 discloses a humidifier. This humidifier, however, is problematic in that the device
may have a poor state of cleanliness because of water remaining in a water reservoir.
Another problem is that this humidifier is not capable of supplying clean air in mixture
because of its monolithic flow path of humidified air.
[0008] KR 10-2018-0094813 discloses a humidifier that supplies heated mummified air. However, his humidifier
has the problem of the increased droplet size because a humidification flow path and
a heating flow path are provided separately. Another problem with this humidifier
is that, the heater operates continuously even with a small heating load, which leads
to supply of humidified air that has an unnecessarily high temperature and excessive
consumption of energy.
