Abstract
Abstract A household refrigerator cabinet comprising a condensing unit compartment at the bottom thereof includes a full width air inlet at the front of the compartment and an air outlet at a rear corner. A serpentine tube condenser mounted adjacent and substantially coextensive with the air inlet occupies the front half of the compartment while the compressor is mounted in the rear corner portion opposite the air outlet. An air circulating fan positioned between the compressor and the air outlet draws air into the compartment through the air inlet and directs air transversely of the rear portion of the compartment toward the air outlet. Partition means between the fan and the air outlet define a muffle chamber having sound absorbing walls for absorbing compressor noises.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A refrigerator cabinet comprising a top wall and side and rear walls defining a condensing unit compartment at the bottom of said cabinet and having an air inlet at the front thereof extending substantially the full width thereof; said rear wall having an air outlet therein adjacent one side wall of an area smaller than the area of said inlet; a fan for circulating air through said compartment, said fan being spaced laterally from said air outlet adjacent said rear wall with its axis generally parallel to said rear wall; partition means defining with the adjacent portions of said rear and side walls a muffling chamber between said fan and said outlet; and a condenser mounted in the forward section of said compartment adjacent and substantially coextensive with said air inlet.
Claim 2
Dependent Claim
131 words
A refrigerator cabinet comprising a top wall and side and rear walls defining a condensing unit compartment at the bottom of said cabinet and having an air inlet at the front thereof extending substantially the full width thereof; said rear wall having an air outlet therein adjacent one side wall of an area smaller than the area of said inlet; a fan for circulating air through said compartment, said fan being spaced laterally from said air outlet adjacent said rear wall with its axis generally parallel to said rear wall; partition means defining with the adjacent portions of said rear and side walls a muffling chamber between said fan and said outlet; and a condenser mounted in the forward section of said compartment adjacent and substantially coextensive with said air inlet.
Claim 3
Dependent Claim
18 words
A refrigerator cabinet according to claim 1 in which said muffling chamber is lined with sound absorbing material.
Claim 4
Dependent Claim
25 words
A refrigerator cabinet according to claim 1 in which said condenser comprises a serpentine tube structure folded to V-shape with the apex facing said inlet.
Claim 5
Dependent Claim
146 words
A refrigerator cabinet comprising a top wall and outer side and rear walls forming a condensing unit compartment at the bottom of said cabinet; said compartment having a relatively large air inlet opening at the front thereof extending substantially the full width of said compartment and a smaller air outlet in one rear corner thereof; a condenser comprising a serpentine tubing having its passes extending substantially the full width of said compartment adjacent said air inlet opening; a compressor mounted in the other rear corner of said compartment rearwardly of said condenser; a fan adjacent said rear wall and said compressor and spaced from said air outlet for directing a flow of air transversely of the rear portion of the compartment and towards said one rear corner; and partition means lined with sound absorbing material defining a muffle chamber between said fan and said air outlet.
Claim 6
Dependent Claim
