Appliance refers to two classes of objects:
- One class of objects includes items that are custom-fitted to an individual for the purpose of correction of a physical problem, such as orthotic appliances.
- The other class of objects includes items that accomplish routine household tasks, using electricity or some other energy input. These are grouped into two categories: small appliances and major appliances. Such items as toilets and sinks are not appliances, but plumbing fixtures[?], because they operate only with water and not with another energy input.
