The hot products of combustion are then caused to pass from the combustion chamber into a radiation heater atop the chamber. Provision is also made to cause the static air rising from the duct to take a separate path into a convection heater section enveloping the combustion chamber. Intermediate the combustion chamber and the radiation heater as a component of the convection heater are deflection means for causing the convection air currents to travel generally outwardly and downwardly in the vicinity of the space heater.

24 t i il l lllt 28 ill I- m SPACE HEATER While it is true in theory that all ambient air heaters causesthe temperature to increase by both convection and radiation means, the instant space heater makes special provision for the two modes of heating. This is achieved by providing a special vertical duct serving as a "convection heater which receives nonturbulent air from a communicating horizontal Y duct after sufficient static pressure has been established therein, the rising air in the convection heater being heated by the heaters combustion chamber'loca'tedproximate thereto. The combustion chamber also receives air for from the horizontal duct and separately conyeys the heated air and the combustion gases into a radiation sectionatop the chamber. Means are disposed in the bottom of .thechamber for imparting turbulence to the air passing therein'for improving the efficiency of combustion. An important feature of the invention is the provision of a deflector to force the convection air currents rising from the vertical duct in the general direction of the floor where it can be used to heat a room space efficiently due to minimizing of heat losses to the upper strata of the air space within the room.
One object of theinvention is, to provide a new and improved space heater. I
Another object of the invention is to provide a space heater which produces uniform and efficient space heating.
A further object of the invention i s'to provide a space heater which heats by both radiation and forced convection.
Other'objects and advantages of the invention may be appreciated on reading the following detailed description of the several embodiments thereof which is taken in accordance with the accompanying drawings, in which:
FIG. 1 is a perspective view of the preferred form of the invention;
FIG. 2 is a section taken on the line 2-2 of FIG. 1;
FIG. 3 is a section taken on the line 3-3 of FIG. 1; I
FIG. 3A is a horizontal section taken on the line 3A-3A of FIG. 3;
FIG. 4 is an exploded view of the components forming the combustion, radiation and convection column of the space heater; and v FIG. 5 is a fragmentary view ofa modified form of combustion chamber for the space heater.
Referring to the drawings it is seenthat space heater is supported on a platform having at one end a handlebar 12 which is an integral extension of a pair of stantions l4 and supporting legs 16. Proximate the other end are mounted wheels 18 for rendering the heater unit portable.
Air is admitted into the heater through horizontal duct 20 being driven by motor driven fan 22. The duct serves as a static box causing the air to rise into the burner proper at such time as sufficient static pressure has developed in the duct.
' The rising air then flows along two avenues, one avenue being provided by the cylindrically formed combustion chamber 24, the other avenue being provided by'the annular air space between the wall of chamber 24 and vertical duct 26 which envelopes the chamber. The top portion of the vertical duct 3 static air at the top of the duct 20 through aperture 23b and -into the combustion chamber 24. The turbulent air in the combustion chamber mixes efficiently. for improved combustion therein.
The rotating and turbulent air and fuel mixture that rises up through the combustion chamber 24 is fired by oil burner 25 ignited by electrodes 29. Fuel for the burner is stored in tank 27. The rising gases in the chamber strikes baffle 31 and circulates above the baffle into the infrared heater section 32 consisting of a cylindrical screen member 33, which is perforated and permits the hot combustion gases toexit through the small perforations causing the member 33 to become incandescent and a source of radiant heat. A protective grille 34 surrounding the screen 33 and top cover 35 therefor house the infrared heater serving thereby to protect the users of the space heater from injury during its operation.
Optionally the entire heating column may be lowered into the duct 30, as shown in dotted line in FIG. 3, so that the several sources of heat are lower to the floor whereby heat loss to the upper air strata is minimized.
The space heater shown in the exploded view in FIG. 4 shows the convection and radiation sections of the heater column as separated units for the sake of clarity.
The modified space heater for burning gas shown in the fragmentary view of FIG. 5 provides a venturi tube 40 serving as a mixing chamber disposed over fuel nozzle 42 within horizontal duct 20. The tube communicates with the combustion chamber 24 within which a baffle plate 31 is disposed close to the ignition means 29, the flame in the chamber being confined to the space between the plate and the outlet end of the venturi tube.
