Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
An arrangement for the internal viewing of the preparation of a food product or the like in a microwave oven; comprising a telescopable tubular member insertable through an aperture in a wall of said microwave oven so as to position the leading end of said tubular member in proximity to the food product in said microwave oven; a generally cylindrical optical viewing device being inserted in said tubular member in coaxially concentric relationship therewith, said viewing device having an outer diameter which is smaller than the inner diameter of said tubular member to form an annular space therebetween; at least one ring-shaped apertured disc extending transversely in the space between said viewing device and said tubular member for radially supporting said device within said tubular member; and a mesh structure being positioned in said tubular member to extend transversely in front of the leading end of said viewing device in said microwave oven so as to form a radiation screen inhibiting the leakage of microwave radiation therethrough.
Claim 2
Dependent Claim
167 words
An arrangement for the internal viewing of the preparation of a food product or the like in a microwave oven; comprising a telescopable tubular member insertable through an aperture in a wall of said microwave oven so as to position the leading end of said tubular member in proximity to the food product in said microwave oven; a generally cylindrical optical viewing device being inserted in said tubular member in coaxially concentric relationship therewith, said viewing device having an outer diameter which is smaller than the inner diameter of said tubular member to form an annular space therebetween; at least one ring-shaped apertured disc extending transversely in the space between said viewing device and said tubular member for radially supporting said device within said tubular member; and a mesh structure being positioned in said tubular member to extend transversely in front of the leading end of said viewing device in said microwave oven so as to form a radiation screen inhibiting the leakage of microwave radiation therethrough.
Claim 3
Dependent Claim
32 words
An arrangement as claimed in claim 1, wherein said mesh structure has a lattice-forming wire matrix facilitating unobstructed viewing of said food product in said microwave oven by said optical viewing device.
Claim 4
Dependent Claim
28 words
An arrangement as claimed in claim 1, wherein said tubular member, aperture disc and mesh structure are formed of an electrically-conductive metal, such as aluminum, copper or brass.
Claim 5
Dependent Claim
24 words
An arrangement as claimed in claim 1, wherein said grid-like disc comprises a radiation screen inhibiting leakage of microwave radiation from said microwave oven.
Claim 6
Dependent Claim
37 words
An arrangement as claimed in claim 1, comprising means for conveying a cooling medium through said annular space between the viewing device and tubular member to cool said viewing device from heat generated in said microwave oven.
Claim 7
Dependent Claim
20 words
An arrangement as claimed in claim 1, wherein said viewing device comprises an endoscope possessing a fiber optic lens system.
Claim 8
Dependent Claim
23 words
An arrangement as claimed in claim 6, wherein said endoscope has an optical lens viewing diameter within the range of about 6-16 mm.
Claim 9
Dependent Claim
16 words
An arrangement as claimed in claim 6, wherein said endoscope lens diameter is about 8 mm.
Claim 10
Dependent Claim
28 words
An arrangement as claimed in claim 8, wherein the opening size of said mesh structure is about 8 mm square to allow for unobstructed viewing through said endoscope.
Claim 11
Dependent Claim
30 words
An arrangement as claimed in claim 1, wherein said tubular member comprises a plurality of coaxial tubular sections in threaded interconnection to impart the desired length to said tubular member.
Claim 12
Dependent Claim
43 words
An arrangement as claimed in claim 10, wherein respectively one of said apertured discs is clamped between the junctures of each of said tubular sections so as to form a plurality of axially spaced supports for said viewing device in said tubular member.
Claim 13
Dependent Claim
47 words
An arrangement as claimed in claim 11, comprising annular flange means and a ring-shaped element for retaining the outer circumference of said mesh structure and each of said discs therebetween, and the contacting end surfaces of said tubular sections imparting an axial clamping force to said components.
Claim 14
Dependent Claim
33 words
An arrangement as claimed in claim 1, comprising further openings in the side walls of said microwave oven for connection of external fiber optic means for lighting the interior of said microwave oven.
