Claim 4

A baseboard heater having a laterally narrow elongated heat source including fins, a backwall extending behind said heat source, a front wall extending forward of said heat source and having a perforate upper section extending toward the backwall over the heat source, said front wall defining with said backwall a common airflow passage within which the heat source is positioned, said common airflow passage extending past said heat source from a common air inlet and terminating in a main hot air outlet, defined by said perforate upper section, above said heat source, a baffle positioned entirely above said heat source and connected to, positioned above, and extending over said front wall perforate upper section, said baffle having a lower edge portion spaced from the backwall and positioned above and to the rear of the heat source, said baffle having an upper edge portion positioned above and forwardly of the heat source, a main air outlet port being defined between the upper edge portion of the front wall and the upper edge portion of the baffle, a wall behind and extending above said baffle and defining with said baffle an open-ended auxiliary air passage located above and to the rear of the common airflow passage, communicating at one end with said common airflow passage behind and above said heat source and opening at its other end above said main hot air outlet and forwardly of said heat source, said baffle having a forwardly downwardly directed mouth section forward of said heat source, defining the upper edge portion of the baffle.

Claim 5

The improvement of claim 2 wherein the front wall has a perforate lower section defining said air inlet, and the upper section is integral with the lower edge portion of said baffle.

Claim 6

A baseboard heater having a laterally narrow elongated heat source including fins, a backwall extending behind said heat source, said backwall being formed of sheet metal and having an integral, forwardly extending channel on its rear surface and a corresponding forwardly extending embossment on its front surface, said embossment being at least coextensive in height and length with said heat source, a front wall extending forward of said heat source and defining with said backwall a common airflow passage within which the heat source is positioned, said common airflow passage extending past said heat source from a common air inlet below said heat source, being narrowed by said forwardly extending embossment, and terminating in a main hot air outlet above said heat source, a baffle positioned entirely above said heat source aNd positioned above and extending over said main hot air outlet, said baffle having a lower edge portion spaced from the backwall and positioned above and to the rear of the heat source, said baffle having an upper edge portion positioned above and forwardly of the heat source, a main air outlet port being defined between the upper edge portion of the front wall and the upper edge portion of the baffle, a wall behind and extending above said baffle and defining with said baffle an open-ended auxiliary air passage located above and to the rear of the common airflow passage, communicating at one end with said common airflow passage behind and above said heat source and opening at its other end above said main hot air outlet and forwardly of said heat source, said baffle having a forwardly downwardly directed mouth section forward of said heat source, defining the upper edge portion of the baffle.

Claim 7

A baseboard heater having a laterally narrow elongated heat source including fins, a backwall extending behind said heat source, said backwall being formed of sheet metal and having an integral, forwardly extending channel on its rear surface and a corresponding forwardly extending embossment on its front surface, said embossment being at least coextensive in height and length with said heat source, a front wall extending forward of said heat source and defining with said backwall a common airflow passage within which the heat source is positioned, said common airflow passage extending past said heat source from a common air inlet below said heat source, being narrowed by said forwardly extending embossment, and terminating in a main hot air outlet above said heat source, a baffle positioned entirely above said heat source aNd positioned above and extending over said main hot air outlet, said baffle having a lower edge portion spaced from the backwall and positioned above and to the rear of the heat source, said baffle having an upper edge portion positioned above and forwardly of the heat source, a main air outlet port being defined between the upper edge portion of the front wall and the upper edge portion of the baffle, a wall behind and extending above said baffle and defining with said baffle an open-ended auxiliary air passage located above and to the rear of the common airflow passage, communicating at one end with said common airflow passage behind and above said heat source and opening at its other end above said main hot air outlet and forwardly of said heat source, said baffle having a forwardly downwardly directed mouth section forward of said heat source, defining the upper edge portion of the baffle.
