Abstract
Abstract A baseboard heater having a housing with finned tubing mounted in an air flow path between a cool air inlet extending along the base of the housing and a hot air outlet extending along the top of the housing is provided with a streamlined diffuser plate having a series of apertures extending along the length of the outlet. A series of vanes are mounted to the diffuser plate for dividing the interior of the housing into a series of plenums corresponding in number to the apertures with a plenum in registry with an aperture. A preferred form of vane has a lower edge which overlies the finned tubing in closely spaced relation and a pair of curved legs diverging outwardly and upwardly in Vfashion from the lower edge and toward the edges of adjacent apertures. The vanes operate to improve the operational cleanliness of the heater by streamlining the flow of air through the heater. Other forms of vanes are also disclosed. The present invention relates to basboard heaters, and more particularly, the present invention relates to baseboard heaters having means for altering the flow pattern of hot air as it exists from the heater to improve the operational cleanliness of the heater.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
176 words
In a baseboard heater having a housing with heat-producing means mounted therein, said housing having an upstanding rear wall for mounting against a partition in an area to be heated and a front wall spaced from said rear wall to form an air flow passage across said heat-producing means in said housing, a diffuser plate mounted in said flow passage above said heatproducing means, said diffuser plate having a deflector flange extending forwardly from the rear wall of said housing and a flange depending from said deflector flange and spanning toward said front wall with a series of apertures therein spaced predetermined distances from one another and from said rear wall, the improvement comprising: means providing a series of vanes for dividing said air flow passage above said heat producing means into a series of plenums corresponding in number to said series of apertures, said vanes alternating with said apertures so that each plenum registers with one aperture, whereby air heated by the heat producing means is split into separate streams before exiting from the apertures.
Claim 2
Dependent Claim
176 words

Claim 3
Dependent Claim
29 words
Apparatus according to claim 1 wherein each vane extends between said rear wall and said deflecting and depending flanges and has a lower edge overlying said heat producing means.
Claim 4
Dependent Claim
43 words
Apparatus according to claim 2 wherein said lower edge is located in closely-spaced relation with said heat producing means and in a vertical plane midway between the edges of adjacent apertures and below a horizontal plane through the lower edge of the apertures.
Claim 5
Dependent Claim
34 words
Apparatus according to claim 2 wherein each vane includes a pair of deflecting legs inclining upwardly away from one another and from said edge, and including means to mount said legs in said housing.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 4 wherein said mounting means includes an outturned flange on each leg and means to fasten said outturned flanges to said deflecting flange.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 4 wherein said legs terminate closely adjacent the edges of adjacent apertures in said series.
Claim 8
Dependent Claim
14 words
Apparatus according to claim 6 wherein said legs have flat surfaces confronting said plenums.
Claim 9
Dependent Claim
14 words
Apparatus according to claim 6 wherein said legs have concave surfaces confronting said plenums.
Claim 10
Dependent Claim
22 words
Apparatus according to claim 1 wherein each vane includes a vertically-disposed planar member located substantially centrally between adjacent apertures in said series.
Claim 11
Dependent Claim
53 words
Apparatus according to claim 1 wherein each aperture in said series has a lengthwise dimension measured in a horizontal direction ranging between one-third and two-thirds of the center to center spacing of said apertures with the ratio of length to width of each aperture being in a range of substantially 1/1 to 4/1.
Claim 12
Dependent Claim
45 words
Apparatus according to claim 1 wherein said diffuser plate has a mounting flange with a depending extension spaced from said rear wall for cooperating therewith to form a dead air space at the rear of the housing for minimizing heat transfer rearwardly from the heater.
Claim 13
Dependent Claim
31 words
Apparatus according to claim 11 wherein said depending extension has a rearward offset coextensive in length with its lower margin, and including means fastening said rearward offset to said rear wall.
Claim 14
Dependent Claim
34 words
Apparatus according to claim 11 including a series of spacers interposed between said rear wall and said depending extension, and including means fastening selected ones of said series of spacers to said rear wall.
Claim 15
Dependent Claim
29 words
Apparatus according to claim 13 wherein said spacers include dimples in said depending extension and said fastening means includes spot welds between said selected dimples and said rear wall.
