Title
(EN) AIR TREATMENT APPARATUS
(FR) APPAREIL DE TRAITEMENT D'AIR
Abstract
(EN)
There is provided an air treatment apparatus comprising an air flow generator that is arranged to generate an air flow, a moisture source that is arranged to introduce water vapour into the air flow, and a water supply system. The water supply system comprises a water tank, a water supply pipe arranged to convey water from the water tank, a water pump arranged to pump water through the water supply pipe, and an ultraviolet light source arranged to irradiate the water passing through the water supply pipe. The water supply system further comprises a flow regulator. The flow regulator comprises a receptacle or flow regulation chamber that is arranged to receive water from the water pump and that is fluidically connected to the water supply pipe, and the receptacle comprises a crest or brim that is arranged to allow water to flow of the receptacle.

La présente invention concerne un appareil de traitement d'air comprenant un générateur de flux d'air qui est conçu pour générer un flux d'air, une source d'humidité qui est agencée pour introduire de la vapeur d'eau dans le flux d'air, et un système d'alimentation en eau. Le système d'alimentation en eau comprend un réservoir d'eau, un tuyau d'alimentation en eau agencé pour transporter l'eau depuis le réservoir d'eau, une pompe à eau agencée pour pomper l'eau à travers le tuyau d'alimentation en eau, et une source de lumière ultraviolette agencée pour exposer l'eau passant à travers le tuyau d'alimentation en eau à de la lumière ultraviolette. Le système d'alimentation en eau comprend en outre un régulateur de débit. Le régulateur de débit comprend un contenant ou une chambre de régulation de flux qui est agencé(e) pour recevoir de l'eau provenant de la pompe à eau et qui est en communication fluidique avec le tuyau d'alimentation en eau, et le contenant comprend une crête ou un bord qui est agencé(e) pour permettre à l'eau de s'écouler du contenant.
