'appliance' is the definition.
I know nothing about this answer so I can't tell whether this works.

'children unbound by rules breaking zester faulty' is the wordplay.
'children' becomes 'ch' (genealogical abbreviation).
'unbound by rules' becomes 'free' (I am not sure about this - if you are sure you should believe this answer much more).
'breaking' means one lot of letters goes inside another.
'faulty' is an anagram indicator.
'zester' with letters rearranged gives 'estzer'.
'free' put within 'estzer' is 'estfreezer'.
'ch'+'estfreezer'='CHEST FREEZER'

(Another definition for chest freezer that I've seen is " Horizontal cold store".)
