An automatically moving floor treatment appliance has a floor treatment element for acting on a surface to be treated, and a control device for controlling the floor treatment element. To increase the area of application of the floor treatment appliance, the control device is embodied to automatically control the floor treatment element as a function of a measuring result from an air parameter sensor in such a way that a floor treatment of the surface to be treated occurs using the floor treatment element and/or to automatically control the floor treatment element as a function of environmental data stored in an external storage device and relating to an air quality.

A dust removal device blows air toward a subject and removes dust. The dust removal device includes a fan arranged to blow air, and a blow-out location changing part arranged to change a blow-out location of air that is blown by the fan and to move toward the subject. The blow-out location changing part is arranged to change the blow-out location in accordance with a height of the subject such that the air is blown toward the subject from a neck down.

An air purifier includes: a housing; a fan in the housing; an outlet in a top face of the housing, air being blown out via the outlet; an air passage spatially connecting the fan to the outlet; and an illumination unit configured to illuminate the air passage, wherein the air passage includes an upstream, first air passage and a downstream, second air passage, the first air passage extends upwards, the second air passage has a curved surface or an inclined surface inclined with respect to the first air passage, and the illumination unit illuminates the curved surface or the inclined surface.

An atomizing diffuser for gaseous environment cleaning: includes a tank cover covered in a water tank to define an oscillation space in the tank cover so as to enhance the effect of oscillating atomized liquid, a housing shield shielding the tank cover and provided with a water filling hole for allowing direct filling of liquid in the water tank and the oscillation space, and an oscillation device with the oscillator thereof coated with a layer of acid and alkali resistant coating for oscillating the alkaline ionized water and other acid-alkaline cleaning liquids in the oscillation space into gaseous cleaning mist that is outputted to the external environmental space for sterilization, cleaning, deodorization, virus elimination, or air purification, and an umbrella-shaped panel with radial ribs provided in the housing is illuminated by light to show the beauty of a paper umbrella, matching the spray effect.

Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a wellness or sense of wellbeing provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for jet lag or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and/or facility personnel, as is instruction, and surveys, including assessing wellness.

Disclosed is a slim-type air processing device adopting a centrifugal fan which is capable of air suction on both sides of the device. The disclosed slim-type air processing device comprises: a housing; a centrifugal fan provided inside the housing; an air suction part which is formed in the housing and is provided in the radial direction of the centrifugal fan; and an air processing part which is mounted in the housing, is disposed on a flow path of air flowing from the air suction part to the centrifugal fan, and processes air passing therethrough in a manner of at least one of dehumidification, humidification, and purification. According to the slim-type air processing device, it is possible to efficiently use the entire area of a filter, and to obtain an effect in which the device has a smaller size and has an improved design.

An aroma diffusion system includes an aroma diffusion unit, an acquisition unit, an identification unit, and an aroma determination unit. The aroma diffusion unit has a plurality of patterns of aromas to be diffused, and diffuses an aroma corresponding to the pattern into a target space. The acquisition unit acquires person information relating to at least one of an activity and a mood of a person in the target space. The identification unit identifies at least one of the activity and the mood of the person in the target space, based on the person information acquired by the acquisition unit. The aroma determination unit determines the pattern of the aroma diffusion unit, based on a result of the identification by the identification unit.

An HVAC air freshener comprises a cylindrical housing having at least one opening in the wall of the housing along the length of the housing, the housing adapted to be inserted through an opening in a planar portion of an HVAC plenum or ductwork, a magnetic ring encircling and attached to the housing near one end of the housing and adapted to magnetically attach to an exterior planar surface of the plenum or ductwork, and a fragrance cartridge inserted into the housing. The fragrance from the fragrance cartridge escapes from the cartridge through the housing opening and into the plenum or ductwork.

A computer implemented method, a computerized system and a computer program product for selective scent dispensing. The computer implemented method comprising: detecting an event, wherein the event is associated with a person entering a predetermined physical area; in response to the detection of the event, determining, by a processor, a scent for the event; and applying, by a dispenser, the scent on the predetermined physical area.
