Kitchen appliance knocked out of shape (5)

I believe the answer is:

stove

I'm a little stuck... Click here to teach me more about this clue!

'kitchen appliance' is the definition.
(stove is a kind of kitchen appliance)

I can't explain the remainder of the clue.

(Other definitions for stove that I've seen before include "Cooking apparatus" , "Votes (anag)" , "Broke a hole in" , "Oven" , "Old cooker" .)

I've seen this clue in The Times.
