Abstract
Abstract An improved toy oven for baking foods quickly that includes a baking chamber with inner and outer parallel walls constructed so as to attain a predetermined temperature rapidly, utilizing a single radiant energy source. The electric bulb heats the surrounding air and establishes a convection current which flows through the baking chamber to heat the food. The toy oven further includes an input shelf and an output shelf that function to provide cooling for the baking pans used with the oven, and their contents. A baking shelf in the baking chamber is arranged to be horizontal and together with the input and output shelves, and input and output doors of said chamber, form a continuous horizontal track upon which a baking pan is placed and pushed into said baking chamber for baking and then onto said output shelf for cooling, prior to being removed from the oven.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
A toy oven for baking foods comprising: (a) a baking pan for receiving foods to be baked; (b) a double walled chamber defining an outer baking chamber between said walls with input and output doors disposed in opposite sides thereof a configuration sufficient to allow the entrance therethrough of said baking pan to the space between said double walls; (c) the inner of said double walls defining a heating chamber and a horizontal baking shelf means for supporting said pan between said double walls and extending from said input door through said baking chamber to said output door; (d) a single electric light bulb for said oven disposed within said heating chamber below said horizontal baking shelf for providing heat for baking said foods there being a convection current flow path from below said baking shelf through the space thereover; (e) means venting to the atmosphere the areas of said baking chamber above said horizontal shelf means; and (f) shell means surrounding said baking chamber and including input and output shelf means.
Claim 2
Dependent Claim
172 words
A toy oven for baking foods comprising: (a) a baking pan for receiving foods to be baked; (b) a double walled chamber defining an outer baking chamber between said walls with input and output doors disposed in opposite sides thereof a configuration sufficient to allow the entrance therethrough of said baking pan to the space between said double walls; (c) the inner of said double walls defining a heating chamber and a horizontal baking shelf means for supporting said pan between said double walls and extending from said input door through said baking chamber to said output door; (d) a single electric light bulb for said oven disposed within said heating chamber below said horizontal baking shelf for providing heat for baking said foods there being a convection current flow path from below said baking shelf through the space thereover; (e) means venting to the atmosphere the areas of said baking chamber above said horizontal shelf means; and (f) shell means surrounding said baking chamber and including input and output shelf means.
Claim 3
Dependent Claim
19 words
The toy oven of claim 1, wherein said input and output doors are normally biased to a closed position.
Claim 4
Dependent Claim
46 words
The toy oven of claim 1, wherein said baking shelf means is comprised of pan support means including a plurality of raised portions for allowing heat to circulate beneath said baking pans and to allow heat from said light bulb to rise above said baking pan.
Claim 5
Dependent Claim
26 words
The toy oven of claim 1, wherein said shell means includes a plurality of cooling fins and slots for venting said baking chamber to said atmosphere.
Claim 6
Dependent Claim
35 words
The toy oven of claim 1, further including a separate pusher means for pushing a baking pan through said input door and into said baking chamber to rest on said horizontal baking shelf for baking.
Claim 7
Dependent Claim
37 words
