20240200807
This application claims priority to Korean Patent Application No. 10-2022-0177802, filed Dec. 19, 2022, whose entire disclosures are hereby incorporated by reference.
The present disclosure relates to a humidifier, and more particularly, to a humidifier that supplies clean humidified air.
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.
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.
Ultrasonic humidifiers have advantages such as converting the water stored in the water reservoir into fine particles and spraying large amounts of mist.
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.
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.
Prior Art Document 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.
Prior Art Document 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.
The present disclosure is directed to overcoming the above problems and others.
Another aspect of the present disclosure is to supply clean humidified air.
Yet another aspect of the present disclosure is to separate and combine a humidification flow path and a cleaning flow path.
A further aspect of the present disclosure is to optimally mix humidified flow and cleaning flow.
A further aspect of the present disclosure is to improve the cleanliness of humidified flow.
A further aspect of the present disclosure is to combine air in a heating flow path and air in a humidification flow path.
A further aspect of the present disclosure is to simplify a flow path structure.
A further aspect of the present disclosure is to minimize flow resistance.
A further aspect of the present disclosure is to guide a flow of air in a given direction.
A further aspect of the present disclosure is to improve air heating and humidification efficiency.
