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.

An air purification device includes a housing configured to house a desiccant material filter and a fan coupled to the housing and configured to cause airflow to pass through the desiccant material filter. Moisture is to be collected from the airflow by the desiccant material filter. The moisture is to be removed from the desiccant material filter via one or more of heat or microwave energy.

A heating, ventilating and air conditioning (HVAC) unit. The unit comprises a heat exchanger or drain pan located inside a HVAC housing that has one or more access openings and ultraviolet light-sensitive components therein. The unit also comprises a light located inside of the HVAC housing and a light shield located between the heat exchanger or drain pan and the light source. The light source includes a network of open-ended cells, each cell having ultraviolet light reflective walls. The light shield is oriented to direct an ultraviolet light from the light source through the open-ended cells towards the heat exchanger or drain pan and away from the one or more access openings and ultraviolet light-sensitive components.

A floating ultrasonic humidifier capable of generating ultraviolet rays according to an embodiment of the present invention includes: a floating body configured to float in a water tub that accommodates water; an ultrasonic humidification generating module disposed in the floating body and configured to generate humidification particles by means of ultrasonic vibration; and an ultraviolet ray generating module provided in the floating body or the ultrasonic humidification generating module and configured to emit light within an ultraviolet region to a space in the water tub.

A water treatment device includes: an insulating divider which divides a space inside a water tank into two treatment vessels adjacent to each other in a horizontal direction, and includes a current carrier which is able to energize water in the two treatment vessels; a treatment unit including a pair of electrodes, a power supply, and a power supply controller; a water supplier which supplies water to each of the treatment vessels; and a draining member which drains water from each of the treatment vessels. The treatment unit includes a detector which detects a level of water in each of the treatment vessels based on an index corresponding to a current value between the pair of electrodes.

A humidifying device for transferring water and/or water vapour from waste air of a waste air flow to supply air of a supply air flow is provided. In the compensating chamber of the housing of the humidifying device, at least one spreading means is arranged, which spreads apart the plate stack of the humidifying device and the housing cover closing the housing in the direction of the longitudinal axis.

A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.

Disclosed is a humidifier with an electrolytic sterilization module, including a water storage tank and an electrolytic sterilization module arranged in the water storage tank. The electrolytic sterilization module includes a housing arranged in the water storage tank, a titanium anode mesh and a titanium cathode mesh. The titanium anode mesh and the titanium cathode mesh are arranged in the housing. The titanium anode mesh is electrically connected with a positive electrode of a power supply by a titanium anode bolt, and the titanium cathode mesh is electrically connected with a negative electrode of the power supply by a titanium cathode bolt, The titanium anode bolt and the titanium cathode bolt penetrate through the housing and the bottom of the water storage tank.

The invention relates in particular to an apparatus (100) for disinfecting at least one room, in particular for one or more persons, preferably a dwelling space or treatment room, for example a treatment room in a building, in particular a sickroom, a patient room and/or an operating theatre, by means of an atomiser. Specifically, the apparatus (100) is characterised in that the atomiser includes a rotatable bell cup (1) for atomising a disinfectant into the room. The invention relates to an associated method and furthermore to the use of a bell cup (1) for atomising a disinfectant in a room for, in particular, one or more persons.

The invention discloses an aromatherapy humidifier, which includes a base, a shell and a cover, which are superimposed sequentially. An atomizing container is arranged on the base. A water storage tank is arranged on the atomizing container. The atomizing container and the water storage tank are contained in the shell. The water storage tank supplies water for the atomizing container and is provided with a mist channel communicated with the atomizing container. The atomizing container is provided with an atomizing assembly for atomizing water into mist and an aromatherapy assembly for volatilizing essential oil. The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and an water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.
