<p>A CONVECTION BLOWER FOR CONVENTIONAL ELECTRIC OVENS An energy-saving, readily removable, portable electric blower for retrofit to conventional 230 volt electric ovens is placed on the oven floor between the heat elements to circulate air through the oven in various directions. One wire of the 115 volt blower motor is coupled by a wire protecting spring metal clip to an element opening in the oven wall for its neutral electrical connection, the second motor wire is coupled to an element conductor so that the blower motor is energized by an oven selector switch. The use of this convection blower can be shown to annually save an average of 350 kilowatt-hours per household.</p> |
