Claims
- 1. A microwave heating system comprising:
- a heating chamber in which a foodstuff may be placed for cooking;
- microwave cooking means for applying microwave energy to the interior of said heating chamber to cook said foodstuff;
- gas sensor means disposed for monitoring gas in said chamber and producing a gas signal indicative thereof;
- means for monitoring the timewise variation of said gas signal from sampled values of said gas signal at different sample times and for determining the desired final level of said gas signal from said timewise variation, said desired final level of said gas signal being different from said sampled levels, said means for monitoring developing a first signal when said desired final level of said gas signal is achieved;
- control means for enabling said microwave cooking means, said control means disabling said microwave cooking means upon receipt of said first signal.
- 2. The microwave heating system of claim 1 further comprising:
- temperature sensor means disposed for monitoring a temperature in said chamber and producing a temperature signal indicative thereof;
- second means for monitoring the timewise variation of said temperature signal from sampled values of said temperature signal at different sample times and for determining the desired final level of said temperature signal from its timewise variation, said desired final level of said temperature signal being different from said sampled temperature values, said second means for monitoring developing a second signal when said desired final level of said temperature signal is achieved;
- said control means disabling said microwave cooking means upon receipt of both said first and second signals.
- 3. The microwave heating system of claim 2 wherein said gas sensor means and said temperature sensor means are disposed in a passageway adjacent said heating chamber; said passageway allowing air to exit said chamber.
- 4. The microwave heating system of claim 3 further comprising a single cook switch operatively interconnected to said control means which when activated causes said control means to enable said microwave cooking means.
- 5. A microwave heating system comprising:
- a heating chamber in which a foodstuff may be placed for cooking;
- microwave cooking means for applying microwave energy to the interior of said heating chamber to cook said foodstuff;
- temperature sensor means disposed for monitoring a temperature signal from the sampled values of said temperature signal at different sample times and for determining the desired final level of said temperature signal from said timewise variation, said desired final level of said temperature signal being different from said sampled values, said means for monitoring developing a control signal when said desired final level of said temperature signal is achieved;
- control means for enabling said microwave cooking means, said control means disabling said microwave cooking means upon receipt of said control signal.
