Systems and methods for inhibiting growth of fungi and other organisms in air treatment systems such as air conditioners, humidifiers, dehumidifiers, and air washers. A pair of electrodes are brought into contact with liquid collected by a collection subsystem of the air treatment system. One of the electrodes includes a bio-inhibiting conductor. Electrical current is caused to pass between the electrodes, causing the bio-inhibiting conductor to be released into the collected liquid.

A humidifier includes a main housing, a fan unit and an air guiding arrangement, which includes a guiding roller and a partitioning assembly. The partitioning assembly is supported in the main housing at a position adjacent to the guiding roller to substantially enclose the water storage compartment. The partitioning assembly defines at least one air slot and an air passage channel, wherein when the fan unit and the guiding roller are driven to rotate, air is drawn from the air inlet and guided to pass through the air slot to reach the water storage compartment for effectively mixing with the water in the water storage compartment to form a predetermined amount of mist. The mist is arranged to pass through the partitioning assembly through the air passage channel and the fan unit, and eventually discharged out of the main housing.

An air disinfector and humidifier combo is revealed. The air disinfector and humidifier combo includes a tank used for storing water and provided with an air outlet, an electrolytic oxygen generator arranged at the tank for hydrolysis of water in the tank to generate ozone water, an ultrasonic oscillator disposed on the tank for atomizing the ozone water in the tank to produce ozone water mist, an air pump, a bubble refiner connected to an air vent of the air pump and mounted in the tank for generating submicron bubbles, and an electronic control unit electrically connected to the electrolytic oxygen generator, the ultrasonic oscillator, and the air pump for control of their operating time. The air disinfector and humidifier combo provides humidification, disinfection and purification functions. The submicron fine bubbles of the ozone water interact better with dirty air to improve disinfection and cleaning effect.

A drain pan includes a light-transmissive member forming at least part of the drain pan and is for transmitting ultraviolet light emitted from a light source. The light-transmissive member has a light-emitting surface that is exposed to the inside of the drain pan and from which ultraviolet light that has been transmitted through the light-transmissive member is emitted.

The present invention provides a humidifier that provides for improved mist generation, to provide for rapid evaporation and rapid humidification and to avoid common problems such as bacteria/pathogen growth associated with conventional approaches. The invention relates to the field of room humidifier devices, and more particularly to an ultrasonic humidifier having improved mist generation for aerosolization of source water.

The humidifier includes a humidifying member, a storage water tank, a circulating water tank, a residual water tank, a supply pump configured to supply water accommodated in the storage water tank to the circulating water tank, a circulating pump configured to supply water accommodated in the circulating water tank to the humidifying member. A fan configured to blow air toward the humidifying member and thereby cause water evaporated to be discharged outside the humidifier, an internal pipe configured to form a flow passage through which water not evaporated by the humidifying member is recovered to the circulating water tank, a drainage member configured to selectively discharge water accommodated in the circulating water tank to the residual water tank, and a controller configured to operate the humidifier in humidity mode based on the water level in the storage water tank.

The invention provides a humidifier with an ultrasonic suspension atomizing head, comprising a water tank, an atomization guiding tube, an atomizing head, and a cover body; the atomization guiding tube is arranged in the water tank, and the side wall of the atomization guiding tube is provided with an opening; the atomizing head is arranged in the atomization guiding tube; the cover body is arranged on the water tank and connected to the atomization guiding tube; an atomization outlet of the cover body is communicated with the atomization guiding tube. The invention has a simple structure; by arranging an atomization guiding tube and an atomizing head, the atomized water vapor does not need to roll from the bottom of the humidifier to the water surface, which achieves a good spray effect, and at the same time, eliminates the sound when the water vapor rolls.

An evaporative air cooling tower includes a housing, a fan at least partially disposed within the housing, and a drawer at least partially disposed within the housing. The drawer includes a liquid tank configured for storing liquid and receiving an ice pack and a pump therein. The evaporative air cooling tower further includes a hose connector positioned adjacent to a top portion of the housing and a first hose disposed within the housing. The first hose includes a first end connected to the pump and a second end connected to the hose connector, such that the pump is configured to pump the liquid stored in the liquid tank to the hose connector through the first hose.

A drain pan includes a light-transmissive member forming at least part of the drain pan and is for transmitting ultraviolet light emitted from a light source. The light-transmissive member has a light-emitting surface that is exposed to the inside of the drain pan and from which ultraviolet light that has been transmitted through the light-transmissive member is emitted.

An evaporative air cooler includes a housing including a top portion and a bottom portion coupled to the top portion. The evaporative air cooler further includes a water tank disposed in the top portion of the housing and configured to store water therein. The water tank includes an upper portion and a lower portion extending from the upper portion. The evaporative air cooler also includes a fan disposed within the housing. The evaporative air cooler further includes a holder removably attached to a back face of the housing. The evaporative air cooler also includes an ice pack at least partially received and supported by the holder. The ice pack is configured for cooling air entering the evaporative air cooler.
