Portable stove

Abstract

A portable stove is provided. The stove includes a frame including an upper portion with an opening and a lower portion. A combustion chamber is positioned directly below the opening of the upper portion of the frame. The combustion chamber is defined by an inner wall, and an outer wall spaced apart from the inner wall to define a cavity therebetween. The inner wall includes a plurality of holes spaced about a periphery. A tank for oil is provided. Any oil, such as vegetable oil, can be used. A feed line directs the oil from the tank into the combustion chamber. A fan is connected to the frame and is in communication with the cavity. The fan blows air into the cavity that travels through the holes and into the combustion chamber to provide air for combustion of the oil. An ignition element is provided for igniting the oil.

What is claimed is: 
     
         1 . A portable stove, comprising:
 a frame including an upper portion and a lower portion, the upper portion including an opening;   a combustion chamber positioned directly below the opening of the upper portion of the frame, the combustion chamber defined by an inner wall, and an outer wall spaced apart from the inner wall to define a cavity therebetween, the inner wall includes a plurality of holes spaced about a periphery, the combustion chamber includes a base with an opening at a first axial end and a cover at a second axial end;   a tank for oil and a feed line that directs the oil from the tank into the combustion chamber;   a fan connected to the frame and in communication with the cavity that blows air into the cavity that travels through the holes and into the combustion chamber to provide the air for combustion of the oil; and   an ignition element for igniting the oil.   
     
     
         2 . The portable stove of  claim 1 , wherein the ignition element is a wick element positioned in the combustion chamber. 
     
     
         3 . The portable stove of  claim 1 , wherein the ignition element is an electrical resistance heating element. 
     
     
         4 . The portable stove of  claim 1 , further comprising a pump that directs the oil from the tank into the combustion chamber through the feed line. 
     
     
         5 . The portable stove of  claim 1 , wherein the feed line includes a spray nozzle at an end feeding into the combustion chamber. 
     
     
         6 . The portable stove of  claim 1 , wherein the feed line includes a control valve that prevents excess oil from entering the combustion chamber. 
     
     
         7 . The portable stove of  claim 6 , wherein a sensor located on the bottom of the combustion chamber actuates the control valve. 
     
     
         8 . The portable stove of  claim 4 , further comprising a battery that provides power to the fan and the pump. 
     
     
         9 . The portable stove of  claim 1 , wherein the oil is vegetable oil. 
     
     
         10 . A portable stove, comprising:
 a frame including an upper portion and a lower portion, the upper portion including an opening;   a combustion chamber positioned directly below the opening of the upper portion of the frame;   a tank for oil and a feed line that directs the oil from the tank into the combustion chamber;   a fan connected to the frame and in communication with the combustion chamber to provide air for combustion of the oil; and   an ignition element for igniting the oil.
