The present invention relates to home freezer

and the accompanying‘drawings. in which simi

throughout the several views.
Referring to the drawings, of which there are
cabinets and is particularly concerned with cab

be used in the home to freeze food and t'o main
tain it at a very low temperature for its preserva
