Definitions
- 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.
- KR 10-2022-0105488 discloses a humidifier.
- This humidifier 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.
- KR 10-2018-0094813 discloses a humidifier that supplies heated mummified air.
- 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.

- the humidifier includes an inlet that branches off from the air flow path and allows a space between the outer case and the inner case and the internal space of the humidification device to communicate with each other. Thus, part of blown air may be admitted to the humidification device and converted into mist.
- a part of air blown by the fan may enter the internal space of the humidification device through the inlet, and the rest may flow toward the discharge opening through the blown air flow path.
- the humidifier may further include a humidification flow path through which air admitted into the humidification device through the inlet flows.

- the mist intake may face the connector and protrude downward from the connector.
- a humidifier may have various modes by providing different flow paths: a humidification flow path and a cleaning flow path.
- clean humidified air may be supplied since the humidification flow path and the cleaning flow path combine near the discharge opening.
- a simplified flow path structure can be provided since the humidification flow path branches off from the cleaning flow path and connects into the humidification assembly.
- a flow of air can be guided in a given direction with less flow resistance since the humidified air flows upward along a wall surface of the water reservoir.
- the cleanliness of water mist to be sprayed can be improved by heating water in a heating chamber.
- the temperature of the humidified air can be increased by allowing the heating chamber and a humidification chamber to communicate with each other.

Abstract
The present disclosure relates to a humidifier. A humidifier according to one aspect of the present disclosure includes: an outer case with an intake opening; a discharge opening that opens to the outside of the outer case; an inner case spaced inward from the outer case; a fan disposed inside the outer case; a humidification assembly disposed inside the inner case and positioned downstream from the fan, that includes a humidification device internally having a space; a air flow path formed between the outer case and the inner case, that extends toward the discharge opening; and an inlet that branches off from the air flow path and allows a space between the outer case and the inner case and the internal space of the humidification device to communicate with each other. Thus, part of blown air can be admitted into the humidification device and then sprayed.

- 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.
