Description

humidifier

Technical Field

The present invention relates to a humidifier, and more particularly to a humidifier capable of supplying water by utilizing an upper water supply structure.

Background Art

A humidifier is a device that vaporizes water and discharges humidified air with a high moisture content. A humidifier can vaporize water and generate humidified air through natural vaporization, heating vaporization, or ultrasonic vibration.

The humidifier disclosed in Korean Patent No. 10-2346621 includes: a shell having an inlet formed on the side and an outlet opening toward the upper side; a water tank arranged inside the shell; a disc assembly that supplies moisture to the air sucked in through the inlet while rotating; and a water supply assembly arranged on the upper side of the shell; the water supply assembly includes: a water supply shell arranged on the upper side of the shell, with a water supply port formed in the center; and a water supply guide located on the lower side of the water supply shell to guide water flowing in through the water supply port.

The above-mentioned conventional humidifier has a problem that the water supply guide and the water tank are separated in the vertical direction, so that the water supplied to the water tank through the water supply guide generates noise while falling.

In addition, there is a problem that the supplied water splashes around when it falls into the sink, so that residual water is generated inside the humidifier, which may breed bacteria such as mold.

In addition, the humidifier has a structure in which the disc assembly, the air supply fan, the fan motor and the water supply housing are arranged on the upper side of the water tank, which makes it inconvenient for the user to separate the water tank for cleaning after using the humidifier.

In addition, there is a problem that the user cannot check the water level of the water tank during the water supply process. Therefore, if the user oversupplies water, there is a problem that water leaks into the humidifier.

In addition, since the structure of the water supply housing is complicated, it is difficult for the user to clean the path through which the supplied water flows. Therefore, there is a problem that the supplied water is contaminated while passing through the contaminated water supply path inside the water supply housing.
