Is a electric can opener patented?

Short answer: specific designs of a electric can opener have been patented many times, but "a electric can opener" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a electric can opener been patented?” but “has my combination of features been described before?” Kitchen gadgets are a crowded, mature field; novelty usually sits in one specific mechanism, the material, or how two familiar functions are combined.
