Is a ceiling fan patented?
Short answer: specific designs of a ceiling fan have been patented many times, but "a ceiling fan" 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 ceiling fan been patented?” but “has my combination of features been described before?” Household products tend to differ in the mechanism (how something attaches, folds, dispenses or cleans) rather than the basic idea.
