Abstract
Abstract A temperature control unit for a microwave oven and the like which includes a sensing device mounted in the wall of a vessel to be placed in a microwave oven, for example, and contact elements in the base of said oven to be positioned in registry with contact elements on the sensing device to place the sensing device in a control circuit for the regulation of time and temperature in conjunction with the oven control.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
93 words
A control for microwave cooking which comprises: (a) a vessel, (b) a temperature responsive means carried by the wall of said vessel, (c) a plurality of spaced contacts on the wall of said vessel connected to said temperature responsive means, (d) a microwave oven and spaced contact means in a microwave oven control circuit, and (e) means mounting said spaced contact means adjacent an oven wall to register with said contacts on said vessel to incorporate said temperature responsive means into a control circuit when said vessel is positioned in said microwave oven.
Claim 2
Dependent Claim
93 words
A control for microwave cooking which comprises: (a) a vessel, (b) a temperature responsive means carried by the wall of said vessel, (c) a plurality of spaced contacts on the wall of said vessel connected to said temperature responsive means, (d) a microwave oven and spaced contact means in a microwave oven control circuit, and (e) means mounting said spaced contact means adjacent an oven wall to register with said contacts on said vessel to incorporate said temperature responsive means into a control circuit when said vessel is positioned in said microwave oven.
Claim 3
Dependent Claim
35 words
A control as defined in claim 1 in which said temperature responsive means is embedded in the bottom wall of a vessel and said spaced contacts are exposed on an outer wall of the vessel.
Claim 4
Dependent Claim
31 words
A control as defined in claim 2 in which said spaced contact means in said microwave oven control circuit comprise a contact ring and a button contact located within said ring.
Claim 5
Dependent Claim
19 words
A control as defined in claim 3 in which said contact ring and said button contact are resiliently mounted.
Claim 6
Dependent Claim
28 words
A control as defined in claim 2 in which said spaced contacts and said contact means are resiliently biased toward each other when said vessel is in place.
Claim 7
Dependent Claim
38 words
A control as defined in claim 1 in which means is provided on said vessel and means is provided in said oven to locate said vessel in proper position for registry of said contacts and said contact means.
Claim 8
Dependent Claim
111 words
In combination, (a) a microwave oven having an apertured bottom wall, (b) a ring mounted on said wall having resilient radial arms extending inwardly and upwardly into a space below said aperture, (c) a conductive contact ring mounted on said arms in said aperture, (d) a bracket support having a free end extending to the center of said rings, (e) a conductive contact on said free end within said conductive contact ring, (f) a cooking vessel, (g) a thermocouple embedded in the bottom of said vessel, and (h) spaced contacts extending to the outer face of said vessel wall positioned to contact respectively said conductive contact ring and said conductive contact.
Claim 9
Dependent Claim
111 words
In combination, (a) a microwave oven having an apertured bottom wall, (b) a ring mounted on said wall having resilient radial arms extending inwardly and upwardly into a space below said aperture, (c) a conductive contact ring mounted on said arms in said aperture, (d) a bracket support having a free end extending to the center of said rings, (e) a conductive contact on said free end within said conductive contact ring, (f) a cooking vessel, (g) a thermocouple embedded in the bottom of said vessel, and (h) spaced contacts extending to the outer face of said vessel wall positioned to contact respectively said conductive contact ring and said conductive contact.
Claim 10
Dependent Claim
37 words
A combination as defined in claim 7 in which means is provided on said vessel and means is provided on said wall to locate said vessel in proper position for registering said contacts and said contact means.
