Abstract
A heated door is formed by two wooden face panels rendered fire-resistant, which are spaced apart by laths which define flues at the base of which are arranged one or more electrical heating elements. Openings are formed in the upper part and the lower part of each of the two face panels and into them are fitted deflectors or they are blocked by covers which are connected to the deflectors by screws. Arrangements are made for supplying power to and regulating the door and making it safe to use. This type of door is usable in dwelling or work spaces.
Claims15
A heated door comprising, two spaced apart wood face panels, at least one of said panels having a lower fresh air inlet opening and an upper heated air outlet opening;
- means defining a plurality of chimneys between said face panels and extending along substantially the entire height of said panels, said chimneys comprising, a plurality of upright wood laths extending between the face panels and extending along substantially the entire height of said panels, and means securing the laths to said face panels in spaced apart relation width-wise of the door;
- the distance between two adjacent laths not exceeding 150 mm;
- electric heating element means in said chimneys in a lower third of said door for heating air in said chimneys to cause flow from said inlet opening to said outlet opening;
- and means for supplying electrical energy to said heating element means.
