Application January 13, 1947, Serial No. 721,855
3 Claims. 1
the wires and keep them black instead of the I preferable red and radiant conditions.
It is therefore an object of this invention to dispose the heating elements with baffles arranged to prevent currents of cold air from striking the elements when heated. Another object is to divert currents of air to be heated in various alternative positions over surfaces heated by the elements and to carry the air when heated into rooms to be warmed.
With these and other objects to be hereinafter stated I have illustratively exemplified my invention by the accompanying drawings of which:
Figure 1 is a vertical longitudinal section of my furnace, Figure 2 is a cross section view thereof taken on line 2-2 of Fig. 1. Figure 3 is a plan view of a preferable form of one of the heating elements. Figure 4 is a perspective view of one of the bafiles with sloping surfaces for heating and diverting currents of air.
Like numerals on the different figures represent like parts. Numeral l represents a substantially rectangular form of furnace housing in its entirety. ll indicates the bottom, 12 and I3 the ends and I4 and 15 the two sides thereof. Adjacent to the top and to the bottom of side 15 are provided grooves 8 and I1 respectively in which is disposed the side wall for convenience in mountin parts inside the housing. Adjacent the upper margins of the ends and sides are shoulders 23 with upturned flanges l9 over which are mounted a top hood or cover 20.
Approximately one third of the distance across the housing from left hand end thereof a partition 2! is mounted for dividing the housing into two chambers 22 and 23 of preferably uneven areas. Near the top of the chamber 22 angle iron brackets 24 are provided for supporting an air filter 25 of any suitable construction in common use. In the cover 20 over chamber 22 is a mouth or opening 26; the edge around this is upturned for a flange 21 to sustain a cold air intake pipe 28. Above the chamber 23 is an outlet opening 29 around which are upturned edges 30 for flanges to support a short section 3| of pipe which connects and opens into a chamber 32 for receiving, creating and dischar ng heated air, through discharge duct 3'5 in pipe supported on flanges 3%.
In chambers 23 and 3-2 are mounted a series of electric heating elements 35, 3?, and 35. These as shown. in Figure 3 consist of a base .6 of any substantial insulating material on which are aflixed ribs M with thimbles 52 for supporting resistance or heating coils 63. i'erminal or lead wires 44a extend outward for connection with any source of electrical current for heating elements.
In order to shield the heating elements from direct impact of cold currents of air passing through the chambers to be heated suit ole baiiles 44, 45, 4E and All are mounted over such heating elements. These bafiles med in general from plates it which are split lohgitudi nally along the lines and the free edges along the slits are sloped upward to form oblique louvcrs over the openings beneath the same as indicated at 56 in Fig. 4. The bellies or lcuvers are positioned. so that the sloping walls E i thereof lean in the direction that currents of air will be moved or driven thro the char hers.
As shown in Figure l. the l 31, 3B and 39 with the louver-s mounted in the chambers .23 angles to each other in such positions the forced into the chamber 22 the bottom thereof through the duct 5? will be caused to strike the louvers on plates M, 55 and A! successively being diverted from one plate and set of louvers to another in the passage of from the duct 5i through the chambers and out through duct 35. Thus the air so passing and impinging against the louvers becomes heated thereby without direct contact with the heating elements. The heating elements in addition to heating the louvers, closely assembled thereover, by radiation also radiate heat outward through the openings 58 for further heating the air as it is passed over the louvers and over the openi--gs and through. the chambers for warming the rooms.
In chamber 22 is mounted any circulating fan indicated as 52 inside a curved walled casing 53, with a fan wheel 54. The air intake between the ordinary blades of the fan are as indicated along the sides thereof at and 53 for forcing the air outward through the duct 5i and drawing the same from any outside source through the duct 26 and chamber 22. Any suitable motor as 53 may be used. to drive the fan as by belt 59.
.4. -4, Never In operation it will be understood that the heating elements are suitably heated by electricity from any suitable source. The motor then operates the fan whereby cold air or fresh supplies of air are drawn by the fan through the mouth 26 and through the chamber 22, and forced through chambers 23 and 32 and over the louvers and above the heating elements and forced out in desirable heated condition through the duct 33 for use in any home. It will be understood also that as the blasts or currents of air do not impinge directly against the heating elements that the latter retain their highly heated and reddened conditions and continue to radiate heat outward against the louvers and through the openings beneath the same with uniform high degrees of heat. In actual use of a furnace built as above described I have been able to produce a great amount of heat and far more than is possible to produce with th same amount of electricity and cost that could be produced otherwise with any other known appliance.
While I have shown and described a particular form or embodiment of my invention, it may be possible for various minor changes to be made without departing from the spirit and scope of my invention and I do not limit the claims of invention to the particular forms as shown and described.
Having described my invention I claim as new for Letters Patent:
1. An electric house furnace, comprising a body providing a relative wide air admitting chamber and a narrower heated air outlet chamber, the air admitting chamber having an air inlet at one end of the chamber and having a single opening for air passage from the air admitting chamber to the heat outlet chamber, a fan mounted in the air admitting chamber to receive air delivered to the air admitting chamber and force such air through the heated air outlet chamber, electrical heating elements arranged in the heated air outlet chamber, bailie plates arranged to overlie each heating element to prevent the incoming air under the infiUBTlCG of the fan to directly contact with such heating element, each baiiie plate being formed with openings overlying the heating elements and formed with deflecting wings arranged in advance of the openings in direction of air flow and inclined in the direction of air flow to cause the moving air passing over the wings to create a suction iniiuence on the heating element to increase the heat withdrawal from the heating element and direct the same in the direction of air flow in the air outlet chamber.
2. A construction as defined in claim 1, wherein the heated air outlet chamber is provided with a heated air outlet pipe which is provided with plates connected to the pipe and inclined inwardiy with respect to each other, and wherein a heat ing element is arranged between each of said plates and the pipe to provide a chamber directly open to the heat of the heating element, each plate being formed with a plurality of wings extending outwardly from the heating element and inclined in the direction of air flow, the plate being open to establish communication between the heating element and chamber enclosing said element and the interior of the heated air outlet chamber under the suction of the moving air passing over the wings to inspire the maximum heat exchange between the heated air outlet chamber and the heating element while preventing the incoming air from contacting directly with the heating element.
3. A construction as defined in claim 1, wherein each heating element is inclosed in a heating chamber provided by a plate secured to the air outlet chamber and terminally connected to the heated outlet chamber to completely isolate the heating element from the incoming air, the plate providing a chamber to be directly heated to the maximum of the heating element, said plates being formed with openings forming the sole outlets of the heat from the heating elements and inclosing heating chamber and acting through the suction of the incoming air by Wings leading from the plate inclined in the direction of air flow to compel the flow of the heated air from the heat chamber and from the inclosed air heating element, to prevent flow of heated air against the direction of air flow, to insure flow of air and heated current in the same chamber enclosing said element and control the direction of such heat flow.
