Description

Humidifier {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 air containing moisture indoors. Humidifiers are equipped with a water tank that stores water, and are classified into ultrasonic, heated, natural evaporation, or combined types depending on the humidification method.

An ultrasonic humidifier is equipped with a vibrator that generates vibration using ultrasonic waves, and sprays water changed into fine particles by the vibration of the vibrator.

Ultrasonic humidifiers have the advantage of changing the water stored in the water tank into fine particles and producing a large amount of spray.

However, conventional humidifiers have a problem in that the cleanliness of the device is reduced due to water accumulated inside the device. Accordingly, a problem arises in which the air sprayed from the device has a high degree of contamination.

In addition, conventional humidifiers have a problem in that the cleanliness of the sprayed humidified air is reduced due to the inclusion of fine dust in the blown air. Fine dust contained in blown air precipitates in water droplets, increasing the level of contamination of humidified air.

Prior document 10-2022-0105488 discloses a humidifier. However, the humidifier has a problem in that the sanitary condition of the device is reduced due to water remaining in the water tank. In addition, the humidifier has a problem in that it cannot supply mixed clean air as the humidified air flow path is standardized.

Prior document 10-2018-0094813 discloses a humidifier that supplies heated humidified air. However, the humidifier has a separate humidifying flow path and a heating flow path, so there is a problem in that the size of the liquid droplets increases. In addition, the humidifier has a problem in that the heater operates continuously even when the heating load is small, thereby supplying humidified air with an unnecessarily high temperature and excessive energy consumption.
