Application No. 10/392,140
From our review of Wenning, we find that figure 1 shows a
first embodiment of a thermally insulated housing 10 which can be
used for a domestic refrigerating appliance, such as a household
refrigerator or freezer (col. 4, lines 34-37). Useful space 11
is lined by an inner housing shell 12. Inner shell 12 is a
tubular element. It is produced by bending a stainless steel
plate whose ends 14 face one another, and through bending, are
connected to one another in a vacuum tight fashion through
welding. The inner element 12 has a rectangular cross section.
The end opposite loading section 13 is provided with a cover 15,
which is manufactured from a stainless steel plate, for example,
by a deep drawing method. Shell bottom 16 forms the rear wall of
useful space 11 while shell wall 17 is designed to run around in
one piece which engages the end section of tubular element 12.
The engagement of the shell wall 17 over the end section produces
an overlap joint between the tubular element 12 and the cover 15.
The tubular element 12 and the cover 15 are connected in a
vacuum tight manner by welding (col. 4, lines 39-60). Outside of
the inner structure is an outer structure, similarly constructed,
as noted by the examiner in the answer. Between the two
