DEVICES AND METHODS FOR TOILET VENTILATION USING A RADAR SENSOR

摘要

A toilet ventilation device includes a housing that defines an air inlet aperture and an air outlet aperture. Within the housing are an air movement apparatus for drawing air into the device, a filter for removing malodorous elements in the air, and a radar sensor for activating the air movement apparatus in response to the presence of a user and, optionally, deactivatin g the air movement apparatus when the user leaves. The toilet ventilation devi ce is configured and arranged to draw air, using the air movement apparatus, fr om the toilet, through the air inlet aperture, into contact with the filter, an d out the air outlet aperture. In one embodiment, the toilet ventilation devic e is disposed over the overflow conduit of the toilet to draw air from the bow l of the toilet, through the overflow conduit, and into the toilet ventilation device. The entire toilet ventilation device is preferably disposed within a tank of a toilet.
