Definitions

  • U.S. patent 3,309,500 issued March 14, 1967 to Reynolds is directed to a flat, rectangular heater adapted to be positioned in a vertical orientation inside the well of a desk.
  • U.S. patent 2,032,622, issued March 3, 1936 to Le Guillou describes a reflector with a reflective surface of which the contour can be altered by the user.
  • U.S. patent 2,479,425, issued August 16, 1949 to Steingruber is directed to a stand-alone heater having a complex internal construction.
  • U.S. patent 2,612,825, issued September 30, 1952 to McCann describes a heating device for feet, the device being suggested for use on the floor within the well of a desk.
  • U.S. patent 2,613,308, La Mirand discloses a radiant heater and tray, with means for supporting the same at an angle to the horizontal.
  • U.S. patent 2,715,668, issued August 16, 1955 to Booker et al., is directed to a panel heater adapted to provide radiant heat.
  • this invention provides a heating unit for desks, comprising: a frame, a substantially flat radiant heating surface supported by said frame, said surface having a periphery, an elongate, substantially U-shaped trough having a reflective inner surface, the trough being supported by said frame and located adjacent a portion of said periphery, an elongate heating element within and parallel to said trough, a reflector flap hingedly mounted with respect to the frame about a swivel axis adjacent the trough but remote from the heating surface, and disposed such that at least a portion of the radiant energy reflected out of said trough by said inner surface is re-reflected by said flap when it has a predetermined angulation with respect to said heating surface, and electrical means for energizing both the heating surface and the elongate heating element.
  • Figure 1 is a top plan view of a heater constructed in accordance with this invention.
  • Figure 2 is a cross-sectional view taken at the line 2-2 in Figure 1 ; and Figure 3 is a simplified wiring diagram for the heater constructed in accordance with this invention.
  • a radiant panel heater 10 includes a frame 12 which includes four external frame members 14, 15, 16 and 17.
  • the frame members 14, 15 and 17 have the cross-sectional configuration shown at the bottom of Figure 2, this configuration including a first outer flange 20, a second outer flange 22, a first inner flange 24, a second inner flange 26, a main wall member 28, and a projection 30 for receiving threaded fasteners and the like.
  • a first external panel 32 is adapted to be received within the space defined between the outer and inner flanges 20 and 24, whereas a second exterior panel 34 is adapted to be received within the space between the flanges 22 and 26.
  • Located within the space between the panels 32 and 34 is a radiant heater element 38 which may be of conventional construction, drawing electrical power and converting this to radiant heat.
  • an elongate chamber 44 in which is disposed a specular heat deflector in the form of a trough having a substantially parabolic section, along with two marginal portions 50 which are received within the spaces between the rightward flanges of the frame members 40 and 16 (rightward as • viewed in Figure 2).
  • an elongate heating element 48 mounted within and parallel to the deflector 46 is an elongate heating element 48, which may be a CALROD (TM) or any other suitable element adapted to give off radiant heat upon electrical energization.
  • TM CALROD
  • the illustrated heater also includes a reflector flap 52 having a reflective surface 54.
  • the flap 52 is hingedly mounted about a swivel axis 56 defined by the internal projection 58 of the frame member 16. The mounting of the flap 52 with respect to the frame member 16 is accomplished in such a way that friction will cause the flap 52 to remain in any desired angular position with respect to the remainder of the panel.
  • the reflector flap 52 is located adjacent the trough defined by the deflector 46, but is remote from the radiant heating panel 38 and from the external panel 32 through which heat from the unit 38 is radiated.
  • the flap 52 has a gentle curvature which is concave toward the panel 32, and that this section is uniform throughout the length of the flap 52. It will thus be understood that at least a portion of the radiant energy reflected from the deflector 46 (and originally generated by the heating element 48) will be re-reflected by the inner surface 54 of the flap 52, the particular angulation of the flap 52 determining the quantity of heat that is re- reflected. Finally, it will be appreciated that the flap 52 is configured so as to allow it to be folded tightly against the heating surface while covering the trough, for ease of shipping, packaging and stacking.
  • the panel 10 includes L-shaped mounting flanges 60 by which the heating unit can be mounted to a vertical surface 62, for example the vertical surface inside the well of a desk.
  • the unit includes a rheostat or other equivalent unit by which the amount of heat generated by the unit can be controlled by the user.
  • FIG. 3 A specific wiring diagram is shown in Figure 3, in which a source 65 of AC power provides the input to an autotransformer 68, of which the output voltage can be adjusted by the sliding contact 70.
  • a resistance 48a representing the heating element 48 in Figure 2 and a further resistance 38a representing the radiant heater element 38, are wired in parallel.
  • alternative wiring diagrams could be provided.
  • the heating unit provided herein when mounted in the well of a desk, permits office temperatures to be reduced while maintaining the necessary heat input to the user. This results in energy savings, improved productivity due to the cooler ambient air surrounding the upper portion of the user's body, and a perception of control over the work environment. Discomfort associated with lowered office air temperature is thus avoided.

Abstract

Un dispositif de chauffage comprend un cadre et une surface chauffante à rayonnement plane soutenue par le cadre. Une partie creuse parabolique à surface interne réfléchissante est montée le long d'un bord du pourtour de la surface chauffante, et contient un élément chauffant allongé. En outre, un volet réfléchissant est monté articulé à proximité de la partie creuse mais éloigné par rapport à la surface chauffante, et il est disposé de façon qu'au moins une partie de l'énergie de rayonnement réfléchie hors de la partie creu par la surface interne réfléchissante est à nouveau réfléchie par le volet, selon son angle par rapport à la surface chauffante.
