Abstract
A portable heating unit is provided with an elongated housing and a tray. The tray may be positioned above the housing. The tray may be secured to a handle of the portable unit along with the housing of the portable heating unit. The tray may also include sloping surfaces of the tray bottom wall and dividers separating compartments of the tray. The tray may also narrow in the direction of airflow from the inlet end to the outlet end of the housing.
Claims19
A portable heater comprising:
- an elongated heater housing having an inlet end and an outlet end;
- a combustion chamber positioned within said heater housing, wherein said combustion chamber and said heater housing define an airflow cooling channel therebetween;
- a tray disposed above said heater housing and adjacent said airflow cooling channel, said tray having a rear portion upstream from a front portion, wherein said tray includes a bottom wall and a projecting sidewall, wherein said sidewall defines a tray opening;
- wherein said front portion of said tray is spaced upstream from said outlet end of said housing;
- and
- wherein said tray narrows in a downstream direction from said rear portion to said front portion to reduce the exposure of heat from said combustion chamber to said tray.

A portable heater comprising:
- an elongated cylindrical housing having an inlet end and an outlet end;
- a combustion chamber positioned within said housing, wherein said combustion chamber and said housing define an airflow cooling channel therebetween;
- a tray having a bottom wall and a sidewall, wherein said sidewall defines a tray opening;
- said tray includes a rear portion upstream from a front portion, wherein said tray narrows from said rear portion towards said front portion to reduce the exposure of heat from said combustion chamber to said tray, thereby said rear portion of said tray includes a first width and said front portion of said tray includes a second width, wherein said first width is larger than said second width;
- and
- wherein said tray includes a saddle member connecting said tray bottom wall to said cylindrical housing.
3 more elements
A portable heater comprising:
- an elongated housing extending along a longitudinal axis and having an inlet end and an outlet end;
- a combustion chamber extending longitudinally through said housing;
- a tray positioned above said housing and having an opening surrounded by a sidewall extending from a bottom wall;
- a saddle member interconnecting said bottom wall of said tray to said housing, wherein said saddle member includes one or more ribs defining one or more apertures therein;
- and
- wherein said saddle member includes an arcuate portion receiving said housing.
3 more elements
A portable heater comprising:
- an elongated heater housing having an inlet end and an outlet end;
- a combustion chamber positioned within said heater housing, wherein said combustion chamber and said heater housing define an airflow cooling channel therebetween;
- a tray disposed above said heater housing and adjacent said airflow cooling channel, said tray having a rear portion upstream from a front portion, wherein said tray includes a bottom wall and a projecting sidewall, wherein said sidewall defines a tray opening;
- wherein said front portion of said tray is spaced upstream from said outlet end of said housing;
- and
- one or more handles connected to said portable heater, wherein said tray is secured at a first attachment to said one or more handles and is secured at a second attachment to said heater housing downstream of said inlet end towards said outlet end.
3 more elements
A portable heater comprising:
- an elongated cylindrical housing having an inlet end and an outlet end;
- a combustion chamber positioned within said housing, wherein said combustion chamber and said housing define an airflow cooling channel therebetween;
- a tray having a bottom wall and a sidewall, wherein said sidewall defines a tray opening;
- said tray includes a rear portion upstream from a front portion, wherein said tray narrows from said rear portion towards said front portion to reduce the exposure of heat from said combustion chamber to said tray, thereby said rear portion of said tray includes a first width and said front portion of said tray includes a second width, wherein said first width is larger than said second width;
- and
- wherein said tray is positioned above said housing and includes opposing overhanging portions laterally extending beyond the outermost lateral extent of said housing in a direction perpendicular to a longitudinal axis of said cylindrical housing.
