Evaporative humidifier and control method thereof
An evaporative humidifier including a water bucket, a tub configured to accommodate water introduced from the water bucket, a humidifying element configured to execute humidification by receiving the water accommodated in the tub and evaporating the received water, and an ultraviolet ray emitting part provided on the tub to emit ultraviolet rays to the tub.
1. An evaporative humidifier comprising:
a water bucket;
a tub configured to accommodate water introduced from the water bucket;
a humidifying element configured to execute humidification by receiving the water accommodated in the tub and evaporating the received water; and
an ultraviolet ray emitting part provided on the tub to emit ultraviolet rays to the tub, the ultraviolet ray emitting part being provided at a position lower than a water level of the water accommodated in the tub,
wherein the tub is provided at an inside lower surface thereof with an opening to accommodate the ultraviolet ray emitting part,
the ultraviolet ray emitting part further includes a water blocking part formed to correspond to the opening, the water blocking part allowing the ultraviolet rays to pass therethrough and preventing the water accommodated in the tub from being introduced into the ultraviolet ray emitting part,
the opening includes an mounting part having a step and extending to an inner side of the opening such that the water blocking part is mounted on the mounting part;
the ultraviolet ray emitting part further includes a water leakage preventing part configured to prevent water from leaking between a gap between the mounting part and the water blocking part, and
the mounting part is configured to prevent the ultraviolet rays from being directly emitted to the water leakage preventing part.
2. The evaporative humidifier of claim 1 , wherein the ultraviolet ray emitting part is provided on a lower surface of the tub.
3. The evaporative humidifier of claim 1 , wherein the water blocking part is provided in a plate shape to form the inside lower surface of the tub by being coupled to the opening.
4. The evaporative humidifier of claim 1 , wherein the water blocking part is provided in a protruding shape protruding inwardly into the tub.
5. The evaporative humidifier of claim 3 , wherein the water blocking part is provided in a protruding tube shape protruding inwardly into the tub.
6. The evaporative humidifier of claim 4 , wherein the opening is provided in a circular shape, and the water blocking part is provided in a cylinder shape, so that the water blocking part is screw-coupled to the opening.
7. The evaporative humidifier of claim 1 , wherein the tub includes a partition part configured to partition a water supply space to which water is supplied from the water bucket from a water storage space configured to supply water to the humidifying element.
8. The evaporative humidifier of claim 7 , wherein the ultraviolet ray emitting part emits ultraviolet rays to at least one of the water supply space and the water storage space.
9. The evaporative humidifier of claim 7 , wherein the ultraviolet ray emitting part is provided adjacent to the partition part.
10. The evaporative humidifier of claim 1 , wherein the ultraviolet ray emitting part further includes an ultraviolet lamp and a power converting part configured to supply an alternating current power to the ultraviolet lamp.
11. The evaporative humidifier of claim 10 , wherein the ultraviolet ray emitting part further includes at least one ground terminal configured to prevent a short circuit.
12. The evaporative humidifier of claim 1 , further comprising a control part configured to control the ultraviolet ray emitting part such that ultraviolet rays are emitted to the water accommodated in the tub before a humidification operation of the evaporative humidifier starts.
13. The evaporative humidifier of claim 1 , further comprising a control part configured to control the ultraviolet ray emitting part such that ultraviolet rays are emitted to the water accommodated in the tub after a humidification operation of the evaporative humidifier is completed.
14. The evaporative humidifier of claim 1 , further comprising a control part configured to control the ultraviolet ray emitting part such that ultraviolet rays are emitted to the water accommodated in the tub at a constant interval during a humidification operation of the evaporative humidifier.
