Definitions

  • a wall furnace having a chamber defined by two flues extending upwardly from the substantially flat top plate of a combustion chamber includes a blower positioned in the chamber so that the blower draws air into the cabinet and forces the air downwardly against the top plate of the combustion chamber and through the flow passages which are formed by spacing the combustion chamber from the walls defining the heater cabinet.
  • This invention relates to wall furnaces for heating rooms.
  • Such furnaces may be installed free standing or pinned to a wall or partially recessed in a wall.
  • a further object is to provide a novel arrangement of the elements of a wall furnace which gives an improved flow of air through the furnace.
  • FIGURE 1 is a front elevational view, partly in section, of my novel wall furnace
  • FIGURE 2 is a front view, partly in section, with portions of the cabinet and combustion chamber cut away, and showing an oil burner element of the gun type in the lower part of the cabinet;
  • FIGURE 3 is a side view with portions of cabinet and combustio chamber cut away;
  • FIGURE 4 is a view of the lower section of the cabinet with an oil burner element of the pot type.
  • the embodiment shown in the drawing utilizes oil burning elements.
  • the invention is not limited to oil burning elements, but may be utilized with gas or other fuels.
  • the embodiment shown in the drawing comprises a cabinet generally indicated at with a base 12, side walls 14, front and back walls 16 and a tap 18.
  • the cabinet is rectangular in horizontal cross section and is adapted to be partially recessed in a wall or it may be pinned to a wall or may be placed free-standing in a room.
  • combustion chamber 20 the walls of which are spaced from the cabinet 10.
  • a combustion chamber 20 in the lower section of the combustion chamber is a conventional oil burner element of the gun type, which is shown schematically and designated 22, with associated conventional oil sup ply lines, fuel controls, pump and the like.
  • the combustion chamber 20 has front and back walls 24 and 26 and side walls 28 and 30.
  • the base 32 of the combustion chamber is supported on horizontal plate 34 in the lower part of the cabinet.
  • the top of the combustion chamber is in the form of a flat plate 36 and adjacent the side Walls 28 and 30 of the combustion chamber, two flues 38 and 40 extend, each arching upwardly and inwardly to connect with a single flue 42 in the upper portion of the cabinet (see FIG. 2).
  • the single flue 42 is connected to exhaust pipe 44 through which the products of com bustion are carried away.
  • the upward and inward arching of the two flues 38 and 40 provides a chamber or cavity 46.
  • a conventional bucket fan and motor desig nated generally at 48 is mounted in this chamber 46.
  • a shelf 50 which divides the cabinet into an upper section and lower section. This shelf has an opening through which the air from the fan passes into the lower section of the cabinet. This shelf permits the creation of suction in the upper portion of the housing in which the fan is located and the creation of considerable pressure in the lower section of the cabinet as the blower is operated.
  • - curved :balfle plate 52 is positioned on the shelf 50 beneath the fan. This plate serves to direct the air to the opening in the shelf 50 and thus increases the efliciency of the fan.
  • Grilled openings 54 and 56 are located in the top 18 of the cabinet. Filter pads 58 are positioned in each of these openings for filtering incoming air. Air from the room is drawn through these openings into the fan, as the fan is operated. Room air also is drawn to the fan through grilled opening 60 in the upper section of the front wall 16 of the cabinet. As shown in FIGURE 1, this opening is directly opposite the intake of the fan.
  • Air also enters the cabinet through grilled opening 62 in the lower section of each side wall 14.
  • Channel members 64 are positioned in the interior of the side walls of the cabinet to provide ducts connecting the grilled opening 62 with the upper section of the cabinet in which the fan is located. The room air travels upwardly through these ducts formed by channel members 64, and serves to cool the cabinet walls. At the same time this incoming air is pro-heated.
  • Air exhaust grill 66 is provided in the front wall of the cabinet. Exhaust grills 68 are located in the lower section of the side walls 14 of the cabinet. Grilled opening '70 may be provided in the back wall 16 of the cabinet for use if the furnace is positioned free-standing on the floor of the room. An additional grill may be provided in the bottom section of the front wall of the cabinet to per mit room air to enter the bottom section of the cabinet to cool the controls for the burner element.
  • FIGURES 1, 2 and 3 show a gun type oil burner
  • FIGURE 4 shows a alternative type of burner, namely, an oil pot burner 72.
  • Supply line, controls, etc. are schematically shown.
  • FIGURES 1, 2 and 3 of the drawing show the general direction of the currents of air cated by the directional arrows in FIGURE 2 through the flue sections 38 and 40 to the flue 42 and the ex haust pipe 44.
  • These flues 38 and 40 serve to preheat the incoming air as it moves to the fan.
  • the fan draws room air into the upper section of the cabinet through the grilled openings previously described. From the fan the air is moved downwardly under considerable pressure into the lower section of the cabinet against the flat top plate 36. As the air strikes the flat plate 36 it is projected upwardly and meets the oncoming downwardly moving air from the fan. This action of the air currents causes the oncoming air from the fan to spread and move evenly and smoothly over the combustion chamber downwardly around the combustion chamber where it absorbs heat. The air moves thence out of the cabinet through the eX- haust grills previously described.
  • the unit is compact and the cabinet is of face area than a single flue and minimum depth. This is obviously desirable in a wall furnace, as pointed out above.
  • the incoming cool .air is first passed over the fan motor so that the motor is cooled.
  • the bifurcated flue provides greater surthereby increases the efiiciency of the heat exchanger.
  • the flat top of the combustion chamber is heated directly by the burner and provides an improved heat exchanger for the air impinged thereon. Fitth, the impingement of the air against the flat top of the combustion chamber provides a smooth flow of air downwardly around the combustion chamber and into the room.
  • a Wall furnace comprising a cabinet having a base, a top and front, rear and side Walls, ports in the cabinet to admit and emit air, a combustion chamber within the cabinet and spaced from the cabinet walls to provide flow passages between the cabinet and the combustion chamber, heating means Within said combustion chamber, a substantially flat plate forming the top of said combustion chamber with two flues extending upwardly from the top plate and joining to form a chamber therebetween, said chamber being in flow communication with the flow passages, and a blower including its motor positioned in said chamber to draw air into said cabinet and force such air downwardly against the top plate of the combustion chamber and through the flow passages in heat exchange relationship with the combustion chamber.
