The present disclosure provides a heating-type humidifier, including a water tank and a base. The water tank is arranged within the base, and the water tank includes a gas guide pipe, a gas outlet, and a water filling port; the gas outlet is communicated with the gas guide pipe. The base defines a cold gas tank and a heating tank that are communicated with the gas guide pipe, and the cold gas tank is communicated with the water tank through a water supply switch. The cold gas tank is communicated with the heating tank through a guide pipe, the guide pipe being a heat dissipation pipe.

A humidifier includes a storage water tank configured to accommodate a predetermined amount of water; a circulation water tank having a smaller capacity than the storage water tank and including a circulation low water level sensor; a supply pump configured to supply water from the storage water tank to the circulation water tank; a circulation pump configured to supply water from the circulation water tank to a humidifying member; a residual water tank configured to accommodate water discharged from the circulation water tank; a drainage member disposed between the circulation water tank and the residual water tank selectively to discharge water from the circulation water tank to the residual water tank and a processor configured to control the drainage member to discharge water from the circulation water tank to the residual water tank when a low water level signal is received from the circulation low water level sensor.

A humidifier has a base and a housing. The housing has a steam exhaust vent and a vaporizer. The vaporizer includes a heating element surrounded by a removable porous sleeve that protrudes downwardly into water within a reservoir of the base. The sleeve wicks the water including its minerals and impurities into contact with the heating element wherein energization of the heating element causes the wicked water to convert to steam that rises through the exhaust vent and from the housing during a humidification mode.

An air conditioner according to the present invention includes: an air flow path through which air flows; a temperature control unit that controls a temperature of air in the air flow path; a humidifier capable of supplying vapor to the air flow path; a blower that has a suction port connected to a downstream opening of the air flow path, and a discharge port from which air sucked from the suction port is discharged; a chamber that has a communication port connected to the discharge port, and a plurality of duct connection ports configured to be connectable to ducts so as to let out air coming from the discharge port through the ducts; and a baffle plate part 8 disposed in the chamber, the baffle plate part overlapping at least partly with the discharge port when seen along a flow direction of air passing through the discharge port.

A vertical humidifier with a stepped evaporator includes a housing. An evaporative water trough is provided inside the housing, and the stepped evaporator is provided in the evaporative water trough. A fan is mounted under the stepped evaporator, and an air inlet end of the fan is communicated with an air inlet of the housing. A water tank is further mounted at the upper portion of the evaporative water trough, the stepped evaporator is mounted around the lower portion of the water tank, and the water tank is further communicated with the evaporative water trough through a water inlet. An air outlet is provided at the upper portion of the housing, and the air outlet is communicated with an air outlet end of the fan. The stepped evaporator is arranged in an airflow channel between the air outlet and the air outlet end of the fan.

An indoor unit for an air conditioner in which the water level of a steam generator is linked with the water level of a supply chamber for supplying water to the steam generator, and a supply floater, which is lowered or raised according to the water level of the supply chamber, opens and closes a supply flow channel for supplying water to the supply chamber. The indoor unit for an air conditioner can control the water supply through the level of water stored in the steam generator.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side. The methods and apparatus includes plurality of heating elements that may be individually and/or selectively addressable by at least three electrode leads.

The mist spray device according to the present invention is formed by including a mist generator configured to generate mists to above water surface of the water contained in a water tank, an air blower and an air guide part configured to form an air passage to allow the air flow generated by the air blower to be moved to a mist discharge port. Particularly, the water tank is disposed with an inlet through which part of the air flow generated by the air blower is introduced and an outlet through which the mists generated by the mist generator are discharged to the air passage, and an amount of air introduced into the water tank can be adjusted using the air inflow adjustment part.
