Abstract
Abstract A portable, gas fired Wok stove adapted particularly for outdoor cooking includes a vertically mounted outer cylinder. A heating chamber is suspended within the interior of the outer cylinder. One end of the heating chamber is open. A burner is carried in the other end of the heating chamber in substantial alignment with the heating chamber open end. A fuel system is carried in the interior of the outer cylinder nestled underneath the heating chamber. The Wok is supported in confronting alignment with the heating chamber open end such that the flow of high temperature gas exiting therethrough impinges on the Wok bottom evenly heating same. The outer cylinder and internally carried heating chamber coact to make the stove relatively insensitive to wind.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
178 words
A portable, gas fired stove adapted particularly for heating a Wok including a vertically mounted outer cylinder having the upper end open, an annular collar adapted to detachably mount on the open end of said outer cylinder, said collar being formed with a relatively large aperture, a heating chamber generally of cylindrical shape and positioned within the interior of said outer cylinder, said heating chamber having one end open, the open end of said heating chamber being sized substantially complementary to said collar aperture and substantially axially aligned therewith, said heating chamber being detachably carried by said collar in such manner as to depend into the interior of said outer cylinder with the open end of said heating chamber being substantially in the plane of said collar, burner means mounted in said heating chamber such that the last-mentioned means is spaced from said collar aperture and substantially axially aligned therewith, and means for supporting the Wok substantially in alignment with said collar aperture and spaced therefrom whereby the high temperature gas exiting therethrough evenly heats the Wok bottom.
Claim 2
Dependent Claim
178 words
A portable, gas fired stove adapted particularly for heating a Wok including a vertically mounted outer cylinder having the upper end open, an annular collar adapted to detachably mount on the open end of said outer cylinder, said collar being formed with a relatively large aperture, a heating chamber generally of cylindrical shape and positioned within the interior of said outer cylinder, said heating chamber having one end open, the open end of said heating chamber being sized substantially complementary to said collar aperture and substantially axially aligned therewith, said heating chamber being detachably carried by said collar in such manner as to depend into the interior of said outer cylinder with the open end of said heating chamber being substantially in the plane of said collar, burner means mounted in said heating chamber such that the last-mentioned means is spaced from said collar aperture and substantially axially aligned therewith, and means for supporting the Wok substantially in alignment with said collar aperture and spaced therefrom whereby the high temperature gas exiting therethrough evenly heats the Wok bottom.
Claim 3
Dependent Claim
15 words
The portable stove of claim 1, ventilation means on said outer cylinder and heating chamber.
Claim 4
Dependent Claim
30 words
The portable stove of claim 2, said ventilation means including a plurality of apertures formed in said outer cylinder and heating chamber to supply air to the respective interiors thereof.
Claim 5
Dependent Claim
22 words
The portable stove of claim 2, fuel control means coupled to said burner to control the flow of fuel to said burner.
Claim 6
Dependent Claim
45 words
The portable stove of claim 4, a source of pressurized fuel, said pressurized fuel source being coupled to said fuel control means and including a pressure vessel sized to fit in the interior of said outer cylinder to be carried therein underneath said heating chamber.
Claim 7
Dependent Claim
36 words
The portable stove of claim 5, said outer cylinder having its other end substantially closed, said pressure vessel adapted to rest on said substantially closed end and be nestled within the interior of said outer cylinder.
Claim 8
Dependent Claim
17 words
The portable stove of claim 6, said Wok support means including finger means carried by said collar.
Claim 9
Dependent Claim
176 words
A portable, gas fired stove adapted particularly for Wok cooking including in combination an outer shield generally of cylindrical shape and mounted vertically, the upper end of said shield being open, an annular collar formed with a central aperture and adaped to mount on the open end of said shield, said collar aperture being defined by an annular lip, a heating chamber generally cylindrical in shape and having one end open, said heating chamber adapted to detachably mount on said collar such that the peripheral region of said heating chamber defining said open end thereof is caused to react on said aperture-defining lip thereby to orient said heating chamber depending into the interior of said shield, burner means carried in the other end of said heating chamber thereby to space said burner means from said collar aperture, and means for supporting the Wok such that the Wok bottom confronts said collar aperture and is spaced therefrom whereby the flow of high temperature gas egressing said collar aperture impinges on the Wok bottom to evenly heat same.
Claim 10
Dependent Claim
176 words
A portable, gas fired stove adapted particularly for Wok cooking including in combination an outer shield generally of cylindrical shape and mounted vertically, the upper end of said shield being open, an annular collar formed with a central aperture and adaped to mount on the open end of said shield, said collar aperture being defined by an annular lip, a heating chamber generally cylindrical in shape and having one end open, said heating chamber adapted to detachably mount on said collar such that the peripheral region of said heating chamber defining said open end thereof is caused to react on said aperture-defining lip thereby to orient said heating chamber depending into the interior of said shield, burner means carried in the other end of said heating chamber thereby to space said burner means from said collar aperture, and means for supporting the Wok such that the Wok bottom confronts said collar aperture and is spaced therefrom whereby the flow of high temperature gas egressing said collar aperture impinges on the Wok bottom to evenly heat same.
Claim 11
Dependent Claim
35 words
The portable stove of claim 8, the mounting of said heating chamber on said collar being such so as to place said open end of said heating chamber substantially in the plane of said collar.
Claim 12
Dependent Claim
44 words
The portable stove of claim 9, said shield being formed with a plurality of ventilation holes, said heating chamber being formed with a plurality of ventilation holes, ventilation holes on said shield and heating chamber allowing air to flow into the respective interiors thereof.
Claim 13
Dependent Claim
25 words
The portable stove of claim 10, fuel control means serially coupled to said burner means to control the flow of fuel to the last-mentioned means.
Claim 14
Dependent Claim
33 words
The portable stove of claim 11, a source of fuel including pressurized vessel means adapted to be carried in said shield substantially underneath said heating chamber and coupled to said fuel control means.
Claim 15
Dependent Claim
38 words
The portable stove of claim 12, the other and lower end of said shield being substantially closed and adapted to support said pressure vessel means such that said pressure vessel means nestles within the interior of said shield.
Claim 16
Dependent Claim
20 words
The portable stove of claim 13, said Wok support means including a plurality of fingers carried on said annular collar.
Claim 17
Dependent Claim
38 words
The portable stove of claim 14, said fingers disposed substantially in the plane of said collar aperture, a grill sized complementary to said collar and adapted to be carried thereon so as generally to cover said collar aperture.
Claim 18
Dependent Claim
43 words
The portable stove of claim 15, said grill sized to fit into said collar aperture and rest on said fingers, said grill being carried in said collar aperture such that the circumferential periphery of said grill abuts said lip and is constrained thereby.
