Abstract
An air conditioner unit includes a blower fan, an inlet grille upstream of the blower fan, and an outlet grille downstream of the blower fan. The air conditioner unit also includes an air filter positioned between the inlet grille and the outlet grille with a belt encircling and enclosing the air filter on four sides. The air conditioner unit further includes a motor operatively connected to the belt. The motor is configured to rotate the belt around the air filter and thereby clean the air filter.
Claims16
An air conditioner unit defining a vertical direction, a lateral direction, and a transverse direction, the vertical direction, the lateral direction, and the transverse direction being mutually perpendicular, the air conditioner unit comprising:
- an inlet grille and an outlet grille providing fluid communication between an indoor portion of the air conditioner and an ambient environment;
- a blower fan positioned in the indoor portion of the air conditioner unit, the blower fan operable to urge air into the indoor portion of the air conditioner unit through the inlet grille and to urge air out of the indoor portion of the air conditioner unit through the outlet grille;
- an air filter positioned between the inlet grille and the outlet grille, whereby air urged by the blower fan passes through and is filtered by the air filter before the air is urged out of the indoor portion of the air conditioner unit through the outlet grille;
- a belt encircling and enclosing the air filter on four sides, the belt comprising internal bristles;
- and
- a motor operatively connected to the belt, the motor configured to rotate the belt around the air filter, whereby the internal bristles of the belt engage outer surfaces of the air filter and remove particles from the outer surfaces of the air filter, whereby the air filter is cleaned as the motor rotates the belt around the air filter.
