Abstract
A humidifier that suppresses formation of a slime, a scale, and a dew bridge in a lower portion of a humidifying member thereby preventing degradation in humidifying performance. The humidifier includes one or more porous metal bodies serving as the humidifying member and including therein a plurality of voids, a fan that blows air to the porous metal body, a water-supplying device (a supply pipe, a reservoir, and a nozzle) that supplies water to the porous metal body, and the porous metal body includes a tip portion formed in a lower end portion, in a protruding shape or a pointed shape.
Claims9
A humidifier comprising:
- a plurality of humidifying members constituted of a foamed metal, having a flat plate shape and having a surface subjected to a hydrophilic treatment, and opposed to each other with a gap therebetween;
- a water-supplying device that supplies water to the plurality of humidifying members;
- a blower device that draws air which passes horizontally through the plurality of humidifying members outside the humidifier;
- and
- a projecting portion comprising a projection or a corner, the projection or the corner projecting along a direction in which air is caused to flow in each of the plurality of humidifying members, the projection or the corner being formed on a lower end portion of each of the plurality of humidifying members, wherein the airflow is preferentially supplied to the projecting portion of each of the plurality of humidifying members in a drying operation in which the water-supplying device does not supply the water to each of the plurality of humidifying members and the blower device causes air to flow to each of the plurality of humidifying members, in comparison to a portion of each of the plurality of humidifying members other than the projecting portion,
- wherein each of the humidifying members is vertically erected and configured such that a thickness of each of the humidifying members becomes smaller from an upper position of each of the humidifying members toward a lower position of each of the humidifying members stepwise or steplessly, and a gap is provided between the water-supplying device and the plurality of humidifying members, and
- wherein the humidifier is configured to selectively perform a humidifying operation in which the water-supplying device supplies the water to each of the plurality of humidifying members and the blower device causes air to flow to each of the plurality of humidifying members.

- a conductor electrode opposed to each of the plurality of humidifying members with a gap therebetween;
- and
- a power source that applies a voltage between each of the plurality of humidifying members and the conductor electrode.
