Air filtration and sterilization system for a fireplace
First Claim
1. A fireplace comprising:
- a combustion chamber enclosure having at least top, bottom and rear panels and defining a combustion chamber for the combustion of fuel;
an outer enclosure including a plurality of panels that define an inner volume sized to receive the combustion chamber enclosure, the plurality of panels being positioned relative to the combustion chamber enclosure to form a plenum system defining an air passage around at least the top, bottom and rear panels of the combustion chamber enclosure, the air passage having an air intake below the bottom panel of the combustion chamber enclosure and an air exhaust above the combustion chamber enclosure;
a first air filtration system disposed within the plenum system and including a filter; and
a blower disposed within the plenum system to draw room air into the air passage through the air inlet and force air out of the air passage through the air exhaust, wherein the blower causes the room air to pass through the filter to remove airborne contaminants from the room air.

Abstract
An air filtration and sterilization system for removing airborne contaminants from air circulated through an air plenum system of a fireplace. Air filtration systems may include particulate, chemical, and ion filtration systems to filter the air. Air sterilization may include ultraviolet, ozone, germicidal coating, and channeled system of ducts systems to sterilize the air. Systems may be used individually or in combination. In addition, optional components, including a warning sensor for indicating when to replace a filter, an automatic initiation sensor for activating and stopping filtration and sterilization, and an air enhancement system for introducing desirable materials into the air, may be provided.

8. A fireplace including an air filtration system, the fireplace comprising:
-
an enclosure defining a combustion chamber and including an outer surface;
a plenum system defining an air passage that extends round at least a portion of the enclosure outer surface, the plenum system including a lower plenum positioned below die combustion chamber in fluid communication with a room air intake, and an upper plenum positioned above the combustion chamber in fluid communication with a room air exhaust, the upper and lower plenums being in fluid communication with each other through the air passage;
a first filtration system disposed within the lower plenum adjacent the room air intake;
a second filtration system disposed within the upper plenum adjacent the room air exhaust; and
a blower disposed within the plenum system to move room air through the air passage, wherein the blower causes the room air to pass through the first and second filtration systems, and wherein the first and second filtration systems remove airborne contaminants from the air. - View Dependent Claims (9, 10, 11, 12, 13, 14)
