Abstract
An air-cleaning apparatus is mounted on a wall to collect particulates suspended in the air through electrical control. In the air-cleaning apparatus, a box is mounted on a wall to house therein a dust-collection unit and an air fan such as cross-flow fan for blowing air. The dust-collection unit collects the particulates suspended in the air by imparting a corona electric charge to these particulates, i.e., by rendering them an electrostatic charge. The box of the air-cleaning apparatus is provided with an air outlet in its lower section and also provided with a forward-protruding air duct in its upper section. The forward-protruding air duct is provided with an air inlet in its leading edge portion.
Claims11
A wall-mounted air-cleaning apparatus for collecting particulates in the air by means of electrical control, said wall-mounted air-cleaning apparatus comprising:
- a wall-mounted box housing a dust-collection unit for collecting said particulates suspended in the air by imparting a corona electric charge and rendering said particulates electrostatic, said box having an air fan provided therein for blowing air, said box having an air outlet provided at a lower section thereof;
- and
- an air duct provided with an upper section of said box and defining a forward-protruding horizontally-extending airway, said air duct having an air inlet on a leading edge, said air duct being empty and serving solely as an airway.
A wall-mounted air-cleaning apparatus for collecting particulates in the air by means of electrical control, said wall-mounted air-cleaning apparatus comprising:
- a wall-mounted box housing a dust-collection unit for collecting particulates suspended in the air by imparting a corona electric charge and rendering the particulates electrostatic, said box having an air fan provided therein for blowing air, said box having a pre-filter, a deodorizing filter and an air fan, said pre-filter, dust-collection unit, deodorizing filter and said air fan being positioned in that order in the direction of the air-flow, said box having an air outlet provided at a lower section thereof;
- and
- an air duct provided with an upper section of said box and defining a forward-protruding horizontally-extending airway, said air duct having an air inlet on a leading edge, said air duct being empty and serving solely as an airway.
