Abstract
A temperature responsive blower control attachment for a wood-burning stove. The attachment is mountable to or seatable on a heated external surface of the stove and provides thermostatically regulated operation of an electrically operated blower or fan that circulates air heated by the stove. Temperature is sensed through an element which is in contact with the heated surface of the stove, but the other circuit elements of the attachment are isolated from and are not subjected to the potentially damaging temperature of the stove surface.
Claims5
A thermostatic control for an electric blower that circulates air heated by a stove, said control including,
- a housing mounting thermostatic means having a temperature receiving face which is positioned outwardly of said housing,
- said housing also mounting a rheostat for controlling the blower speed, an electric socket for receiving an electric plug from the blower, and circuit means including said thermostatic means and said plug for establishing an electrical circuit between the blower plug and an external source of power when the temperature receiving face of said thermostatic means senses a temperature above a predetermined minimum,
- said control also including spacing means which in use is positioned between said housing and a heated surface of said stove, thereby to separate the housing from the stove surface and to provide an air space between the stove surface and the housing,
- said spacing means spacing the housing from the stove so that the temperature receiving face of the thermostatic means is in thermal engagement with said heated surface of said stove.
