Definitions
- This invention relates to electrical heaters of the type installed on ceilings. More particularly, it relates to a novel ceiling heater having multiple air paths for coohng the fan motor and for heat insulating the fan motor, ceiling and associated wiring from the heating element thereof.
- Prior art heaters are generally spaced some distance from the ceiling to provide a large insulating air space between the heater and the ceiling. Such heaters are not only ungainly in appearance, but the resulting poor circulation to and from the dead air space causes a loss in efficiency.
- the heater wiring must also be protected to prevent destruction of the insulation.
- High temperature insulation is used in the heater itself but wiring in the connecting junction box generally will be subject to destruction at lower temperatures.
- Special provisions to protect the already existing wiring from overheating have been required in prior art electric ceiling heaters. Many prior art heaters have their air intake adjacent their heated air outlet. Hot air blown from the heater is pulled back into the cool air intake to be heated again. This short circuiting of the air flow results in decreased efficiency.
- Another object of the invention is to provide a heater of the above character wherein the junction box wiring for the heater is protected against disintegration by heat.
- Another object of the invention is to provide a heater of the above character wherein the baflies providing multiple air paths through the heater are also utilized to support heater components while keeping heat conducted to the ceiling and associated wiring at a minimum.
- Another object of the invention is to provide a heater of the above character with the air intake located on its bottom and the heated air outlets located on the heater sides, for better distribution of heat and more efiicient circulation.
- a further object of the invention is to provide an electric heater of the above character that will not prodce excessive noise after extended use.
- Another object of the invention is to provide a heater of the above character that is inexpensive to manufacture and durable in use.
- FIGURE 1 is a perspective view of the heater of my invention
- FIGURE 2 is an exploded perspective view of the heater of my invention.
- FIGURE 3 is a side sectional view taken along lines 33 of FIGURE 1.
- Electrical heaters adapted to be installed on room ceilings have a great variety of applications and may be used to supplement the built-in heating system of a home or other building. Such heaters have found extensive use in bathrooms, garages, sheds and similar outbuildings that require heating only occasionally. These ceiling heaters also are utilized to a great extent in tropical or semitropical climates when unseasonably low temperatures occur.
- Electric heaters heretofore provided for the above described uses generally have a single air path through the heater.
- radiated and conducted heat is permitted to be transmitted to the housing panel adjacent the ceiling, resulting in a dangerous fire hazard.
- many of the prior art ceiling heaters have to be spaced a considerable distance from the ceiling. Such construction results in an unpleasant appearance of the heater and in inefiicient utilization of the radiant heat that is trans mitted to the upper panel of the heater air path.
- Such heaters are generally installed to utilize existing building Wiring and are connected to a standard junction box on a ceiling. Since high temperature insulation is not generally provided in common household wiring the junction box must be protected against overheating.
- the present invention obviates a number of the prob lems found in prior art heaters while maintaining low cost of production and attractive appearance of the heater.
- the present heater provides for multiple air paths through the heater structure to cool the heater motor and to efficiently remove heat from the heater baflies directing airflow therethrough.
- the baffling arrangement of the heater prevents transfer of radiated and conducted heat to the ceiling of the room and to the junction box wiring.
- the ceiling heater of the present invention employs a novel balanced stress arrangement for holding the enclosure thereof together.
- some parts are under bending stress, others under tensional stress, and yet others under compressive stress, all balanced such that heat cycling of the unit cannot open up clearances to allow any of the members to rattle.
- a single accessible fastener is provided so that working elements of the heater may be conveniently installed on a ceiling and the heater housing then installed around them. The housing furthermore may be easily removed for cleaning and servicing of the heater.
- openings 12 allow the passage of air through an area in bottom 14 substantially co-extensive with the air moving portions of the fan 10.
- the imperforate outer portion of bottom 14 prevents recirculation of air at the periphery of fan 10.
- a perforated decorative screen 15 is fitted just above bottom 14.
- a main partition 16 directs the majority of the .air in a primary path as indicated by the arrows 18 past heating elements generally indicated at 20 and outwardly in all directions through openings 22 in a grill generally indicated at 24.
- a secondary air path passes through opening 26 in partition 16 and past the fan motor 39 as indicated by arrows 28 to cool the heat producing elements thereof. This secondary air flow is divided, most of it flowing between partition 16 and a top plate 32 and radially therefrom. Some air may flow through opening 34 in top plate 32 and thence outwardly beneath a top panel 38 indicated by arrows 36.
- top plate 32 and top panel 38 are parallel and spaced from one another to provide the various air paths through the heater.
- Motor is located in the upper air paths of the heater to be cooled thereby while the ceiling 40 and wiring in junction box 44 are cooled by the air stream between top plate 32 and top panel 38.
- partition 16 is supported in its intermediate position between top plate 32 and bottom 14 by a plurality of brackets 46 whose horizontal portions 46a may be spot-welded to top plate 32.
- Grill 24 is formed from a flat sheet of metal.
- Bottom 14 has an upstanding flange 48 while top plate 32 has a depending flange 50 so that grill 24, which is interposed therebetween, is resiliently bent into a circle to press radially outwardly against flanges 48 and 50.
- Grill 24 is fitted tightly between bottom 14 and top plate 32 to avoid rattling during operation of the fan. This tight fit is accomplished by a spring-type bracket, generally indicated at 52 in FIGURES 2 and 3.
- this bracket includes three resilient prongs 54, 56 and 58 which extend radially from and are secured to a central disc 60, thence substantially upwardly to terminate in hook-like portions 54a, 56a and 58a. These hook-like portions extend through suitably positioned openings 62 in partition 16 and resiliently press outwardly against the outer edges of openings 62.
- a threaded stud 61 extends through the central portion 14a of bottom 14 and nut 63 is threaded thereon.
- top panel 38 may be conveniently secured to the ceiling of the room by way of a bracket member 68 having right angle flanges 68a interfitting with upstanding flange 38a on top panel 38, these flanges being provided with suitable holes 70, the parts being held together by screws 72.
- bracket 68 is shaped to be secured to a junction box, generally indicated at 44, of standard and well known construction and containing the usual electric wiring for various types of electric fixtures. Bracket 68 is held in this position to support the entire heater assembly by screws 76 secured in the flanges 78.
- Motor 36 is preferably a standard A.C. motor which fits within openings 26 and 34 in partition 16 and top plate 32, as can be seen in FIGURE 3 with its upper portion extending through an opening 38b in top panel 38. It is held in this position by suitable bolts and nuts, generally indicated at 86, which securely fasten the motor to the top panel 38. Still referring to FIG- URE 3, the motor shaft 82 extends downwardly and the fan 19 is secured thereto by a collar 84 and a set screw 86.
- the heating element 26 comprises a series of sections 86 preferably curved in shape and held in position by s ring clips, generally indicated at 88, which in turn support ceramic collars 90.
- these spring clips include angle-shaped legs 92 which extend through suitable holes 34 i partition 16 to rest upon the top side thereof.
- These clips 88 are designed to spring outwardly so that the angle-shaped legs press against the edges of holes 94 to thereby hold the heater assembly 20 firmly in the position shown and to avoid rattling during operation of the fan.
- Suitable wiring extends from the junction box, through insulators 98 and 100 in top panel 38 and top plate 32 respectively, to be connected to binding posts or the like, generally indicated at 102, which are preferably mounted in the position shown on partition 16.
- Suitable electrical connections are made between the motor 30 and the heating elements 20 to provide the necessary electric power, and this wiring will, of course, include proper switch connections for controlling the heater assembly from a wall switch (not shown) or the like.
- the heater is turned on by a remote switch (not shown) to supply current to the heating elements 20 and fan motor 36. Intake air is drawn upwardly and the major portion thereof is directed as shown by arrows 18, beneath partition 16 past the heating element 20 and then through the grill 24 to be circulated through the room. A minor portion of the air goes through opening 26 in partition 16 and around the motor for cooling purposes.
- Air also flows through opening 34 and out between top plate 32 and top panel 38 thus coacting with top panel 38 to prevent overheating the ceiling.
- the dead air space between the top panel 38 and the ceiling provides added protection against overheating of the ceiling and junction box wiring.
- the heater of the present invention is thus extremely efficient and same in operation.
- the directing of multiple air paths through the heater results in rapid removal of heat and distribution throughout the room.
- the heater of my invention is inexpensive to manufacture since the great majority of parts can be easily stamped from sheet metal and assembled with a minimum of labor. Further there is a minimum of short circ-uiting of heated air back into the heater, and there is no direct hot air blast below the heater since heated air is circulated outwardly from all sides of the heater.
- the heater of the present invention is extremely easy to install, clean, and service, merely requiring the removal of the single nut 63.
- a balanced stress arrangement is inherent in the structure preventing rattling of the various parts during heater operation.
- An electric heater for installation on a ceiling comprising in combination:
- a housing for the electric heater comprising (1) a perforated grill extending around the periphery of the heater, including at least a portion of the peripheral areas above and below said main partition to provide an air outlet around said housing, and
- said bottom panel having means forming an air intake opening therein 2.
- said fan blades are pitched so as to direct air upwardly through said air intake orifice and against said main partition and said aperture is of smaller diameter than said fan but large enough to permit a small portion of the upwardly directed unheated air to pass over the heat producing portions of said motor.
- An electric heater comprising in combination:
- bracket comprises (1) at least three resiliently bendable wire prongs connected together at a fastener attached to said bottom plate, and wherein (2) said three wire prongs are engageable in openings in said main partition and when so engaged are urged against the edges of said openings.
- An electric heater comprising in combination:
