Description

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 is a top view of the fireplace insert also showing an electrical outlet receptacle to power an “inside” artificial flame display, and a fragerance strip location.

FIG. 2 is a right quarter rear view in perspective showing general pipe installation detail and said receptacle.

FIG. 3 shows the general configuration of the serpentine optional electric heating rod design arrangement and disposition 21 prior to insertion in the forwardly disposed horizontal exiting heat pipes: another usual electric heating rod design is the “ladder” design arrangement (not shown). The said woven wire screen (or metal grate 22), plus the consumable fuel rests upon the said exiting air heating pipes.

FIGS. 4 and 5 show the general disposition of a draft control door 16, hinged on the near (lower) edge, smaller manual draft adjustment 17, plenum chambers (hobs) fans 11 and control 18, heater rod control 19, and ash collector pan 20. Also shown is the fireplace enclosure frame 14 and glass doors 15.

As illustrated in the drawing, FIGS. 1, 2, 4, and 5 show the plenum chambers 10, with axial air intake fans 11, supplying air being heated through one or more circular (or any shaped) pipes or tubings 12, rising from the said plenum chambers up the right and left sides of the fireplace cavity, converging across the top of the said fireplace cavity, directed down the rear surface of the said fireplace cavity, and redirected forwardly into the attending room over a fragrance strip 24 in a generally horizontal plane from the said fireplace cavity through one or more air outlets 13. Also shown is electrical outlet 23.

Claims

1. An improvement in the art relating to a residential fireplace insert fitted into a standard fireplace cavity. The insert is simply a box structure (plus front enclosure) loosely formed of metal pipes (or tubings) and using one or more plenum chambers (hobs) with suction fan(s). The fans supply air under pressure to be heated while rising up the right and left sides of the said fireplace cavity through one or more circular or otherwise shaped heating tubes. The tubes converging across the top of the said fireplace cavity, proceed down the rear of the said fireplace cavity and are directed forwardly into the attendant room from near the bottom of the said fireplace cavity using natural radient heat (and/or supplimental electric heat). The exit openings can be located between the heat-providing iron or wire screen grate level above and the ash collector pan level beneath. Said fireplace insert incorporates all related draft, fan, and heat-regulating controls.
