Abstract

A humidifier according to one embodiment of the present disclosure comprises: a water tank forming a space for storing water; a first humidifying water tank connected to the water tank through a supply pipe and having a heater disposed therein; a first water level sensor for detecting the water level of water stored inside the first humidifying water tank; a second humidifying water tank connected to the first humidifying water tank through a first connecting pipe and a second connecting pipe and having a vibrator disposed therein; a second water level sensor for detecting the water level of water stored inside the second humidifying water tank; and a pump disposed in the second connecting pipe. When the humidification operation is turned on, if the first water level is detected by the second water level sensor, the pump operates to perform a residual water recovery operation in which the residual water in the second humidifying water tank is recovered into the first humidifying water tank through the second connecting pipe.

Description

Humidifier The present disclosure relates to a humidifier, and more specifically, to a humidifier that supplies humidified clean air. A humidifier is a device that supplies moisture-containing air into a room. Humidifiers are equipped with a water tank to store water and are classified into ultrasonic, heated, natural evaporation, or hybrid types depending on the humidification method. A humidifier is a device that vaporizes water and emits humidified air with a high moisture content. Humidifiers can generate humidified air by vaporizing water through natural evaporation, heated evaporation, or ultrasonic vibration. Each vaporization method has its advantages and disadvantages. In the case of natural evaporation, there is a problem in that the user must frequently manage the humidification medium used. Ultrasonic humidifiers are equipped with a transducer that generates vibrations using ultrasound, and they spray water transformed into fine particles by the vibration, offering the advantage of a high mist output. However, vaporization via ultrasonic vibration presents several challenges: the humidified air may not circulate actively within the room due to the atomization of supplied water; unpleasant humidified air may circulate if unsterilized water is used; and the ultrasonic transducer is vulnerable to high temperatures. In the case of heated vaporization, safety accidents may occur if hot humidified air is discharged directly. Prior art Korean registered patent KR 10-0158806 discloses a heater-type ultrasonic humidifier that humidifies heated water. Generally, air purifiers and humidifiers are manufactured and used as separate products, but in response to the diverse demands of consumers, products that combine both humidification and air purification functions into a single product are being released. For example, the prior art Korean published patent KR 10-2005-0024044 discloses a humidification device that also serves as an air purifier. Meanwhile, as described in the prior art, in a humidifier or a device providing a humidification function, if water accumulates or moisture remains inside when providing the humidification function, the cleanliness is compromised and there is a possibility that contaminated humidified air may be discharged. Therefore, internal hygiene management of the humidifier is necessary, and it is desirable for hygiene-related operations to be performed automatically under appropriate circumstances.
