Abstract
A portable forced air unit having a housing provided with an air driving element arranged between an air inlet and an air outlet, the air outlet feeding the forced air beneath a fixed room heat exchanger e.g. baseboard or convector heater with which the unit is designed to operate. Thermostats, responsive to the temperature of the room in which the unit is operating and the temperature of the heat exchanger, serve to control the air driving element.
Claims11
The combination with a fixed heat exchanger, disposed above the floor of a room, of a unit for forcing air through said heat exchanger, said unit comprising:
- an elongated housing portably resting on the floor wholly below the air outlet of said heat exchanger, said housing having a large cross-section portion forming an air duct and lying in front of said heat exchanger, and a projection formed on said housing and integral with said large cross-section portion and extending over substantially the entire length thereof, said projection communicating with said duct and being of smaller cross section than said large portion;
- an elongated air outlet formed in said projection facing upwardly for directing forced air upwardly through said heat exchanger;
- an air inlet formed in said large portion facing away from said heat exchanger for drawing in room air;
- means provided in said large portion between said inlet and said elongated outlet for forcing air therethrough;
- and
- a thermostat in said housing connected to said air forcing means and responsive to the temperature of said room for controlling said air forcing means.
