Abstract
A heated air circulator adapted to be placed against a radiant-type heating stove. The housing of the circulator, which defines a chamber therewithin, includes upright back and side walls which are unjoined along their adjacent upper edge portions. A plurality of spaced-apart, transverse fold lines on the back and side walls, where the same are unjoined, permit portions of these walls to be folded over to form a chamber top at a height conforming to the height of the stove. The circulator includes a damper regulated by a temperature-responsive spring whereby flow of unheated air into the chamber increases as the temperature within the chamber increases.
Claims7
A heated air circulator adapted to be placed adjacent a radiant-type heating stove, comprising
- a housing including wall means defining a chamber therein, said wall means comprising an upright back wall and opposed upright side walls, said back and side walls being unjoined along their adjacent upper edge portions, p1 means defining a plurality of spaced-apart, transverse fold lines on said back and side walls, permitting portion of said walls, where the same are unjoined, to be folded over to form a chamber top at a height conforming to the height of said stove, and
- flow means for controlling the flow of air through said chamber.
A heated air circulator adapted to be placed adjacent a radiant-type heating stove, comprising
- a housing including wall means defining a chamber therein, said wall means comprising a sheet of metal having a central section forming a back wall and opposed side margins folded inwardly therefrom to form a pair of opposed upright side walls, with upper portions of said central section and said side margins being unjoined along their adjacent edges,
- means defining a plurality of spaced-apart, transverse fold lines on said back and side walls, permitting portions of said walls, where the same are unjoined, to be folded over to form a chamber top at a height conforming to the height of said stove,
- intake and exhaust openings defined in said wall means, permitting flow of air through said chamber,
- a damper plate mounted on said wall means adjacent said intake opening for movement between open and closed positions, wherein said plate controls flow of air through said intake opening,
- temperature-responsive means for moving said plate toward its open and closed positions in response to temperature variations within chamber, said temperature-responsive means including a temperature-responsive spring mounted within said chamber and connected to said plate to bias said plate toward its closed position, and a second spring mounted outside said chamber and attached to said plate to bias said plate toward an open position, and
- a motor-driven fan for forcing heated air from said chamber through said exhaust opening.
