Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
223 words
In an air conditioner, a combination comprising a motor and a pair of centrifugal fans driven by said motor and arranged on opposite sides of and along a common axis with said motor; and a casing surrounding said motor and said fans, said casing comprising two integral main components meeting each other along a plane including said axis and being fixedly connected to each other, each of said components having a plurality of walls extending transverse to said axis and respectively aligned with transverse walls of said other component so as to divide said casing into two chambers respectively housing said fans and a third chamber located between said two chambers and housing said motor, each of said transverse walls being provided with substantially semi-circular opening forming with the semicircular opening in the corresponding transverse wall of the other component as axial inlet opening of circular cross section for the respective fan and each of said components having a curved wall between the transverse walls defining each of said two chambers and meeting the curved wall of the other component in said plane so that the meeting curved walls define a scrollshaped space surrounding a respective one of said fans, one of said components being formed in each of said curved walls with a substantially tangential outlet opening communicating with the respective space.
Claim 2
Dependent Claim
223 words
In an air conditioner, a combination comprising a motor and a pair of centrifugal fans driven by said motor and arranged on opposite sides of and along a common axis with said motor; and a casing surrounding said motor and said fans, said casing comprising two integral main components meeting each other along a plane including said axis and being fixedly connected to each other, each of said components having a plurality of walls extending transverse to said axis and respectively aligned with transverse walls of said other component so as to divide said casing into two chambers respectively housing said fans and a third chamber located between said two chambers and housing said motor, each of said transverse walls being provided with substantially semi-circular opening forming with the semicircular opening in the corresponding transverse wall of the other component as axial inlet opening of circular cross section for the respective fan and each of said components having a curved wall between the transverse walls defining each of said two chambers and meeting the curved wall of the other component in said plane so that the meeting curved walls define a scrollshaped space surrounding a respective one of said fans, one of said components being formed in each of said curved walls with a substantially tangential outlet opening communicating with the respective space.
Claim 3
Dependent Claim
19 words
A combination as defined in claim 1, wherein each of said main components is integrally molded from plastic material.
Claim 4
Dependent Claim
110 words
A combination as defined in claim 1, wherein said casing is of substantially parallelepipedon shape, said one component having a top wall in which said outlet openings are formed and extending substantially parallel to said plane, and further including an evaporator supported on said top wall, and condenser supported on the other component and extending along said casing upwardly beyond said top wall, a compressor supported on said other component, and a third component supported on said top wall and forming passages for directing an air stream emanating from one of said fans over said condenser and an air stream emanating from the other of said fans over said evaporator.
Claim 5
Dependent Claim
16 words
A combination as defined in claim 3, wherein said third component is formed from heat-insulating material.
Claim 6
Dependent Claim
14 words
A combination as defined in claim 4, wherein said heat-insulating material comprises expanded polystyrene.
