Is a slow cooker patented?
Short answer: specific designs of a slow cooker have been patented many times, but "a slow cooker" 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 slow cooker 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.
