Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
An apparatus for treating laundry which utilizes a spin drying perforated drum disposed within a surrounding housing and wherein a circumjacent space is defined between the drum and the housing, the provision therewith of a fluid pressure source connected in flow communication with the circumjacent space to direct a pressurized fluid flow into the space and thence inwardly through the drum perforations, means for selectively curtailing the flow from the pressurized source, means for subjecting the interior of the drum to suction, the fluid pressure source being a compressed air source which is blower interconnected to the housing by an inlet conduit, an open end on the drum connected in communication with the outlet end of a laundry washing unit by means of a laundry transfer chamber, suction means for creating negative pressure within the drum, and the suctions means including an outlet conduit from the transfer chamber which leads to the intake side of a blower.
Claim 2
Independent Claim
157 words
An apparatus for treating laundry which utilizes a spin drying perforated drum disposed within a surrounding housing and wherein a circumjacent space is defined between the drum and the housing, the provision therewith of a fluid pressure source connected in flow communication with the circumjacent space to direct a pressurized fluid flow into the space and thence inwardly through the drum perforations, means for selectively curtailing the flow from the pressurized source, means for subjecting the interior of the drum to suction, the fluid pressure source being a compressed air source which is blower interconnected to the housing by an inlet conduit, an open end on the drum connected in communication with the outlet end of a laundry washing unit by means of a laundry transfer chamber, suction means for creating negative pressure within the drum, and the suctions means including an outlet conduit from the transfer chamber which leads to the intake side of a blower.
Claim 3
Dependent Claim
34 words
The invention of claim 1 further including an inlet conduit directing the fluid pressure source to the circumjacent space and wherein the inlet conduit and the outlet conduit are connected to a single blower.
Claim 4
Dependent Claim
33 words
The invention of claim 1 wherein the outlet conduit includes a widened intermediate portion at a point along the length thereof remote from the transfer chamber which serves as a laundry separating chamber.
Claim 5
Dependent Claim
16 words
The invention of claim 3 wherein the separating chamber has a selectively closable waste air outlet.
Claim 6
Dependent Claim
80 words
The invention of claim 3, wherein the outlet conduit is provided with a valve located between the separating chamber and the transfer chamber, a branch conduit communicates from a port in the sidewall of the outlet conduit to a branch conduit, and the port is located between the valve and the transfer chamber, an optionally operable routing means is provided within the outlet conduit and adjacent the port, and the branch conduit is adapted for connection to a drying unit.
Claim 7
Dependent Claim
29 words
The invention of claim 3 wherein the separating chamber has, on the bottom thereof, a closable outlet aperture for the removal of laundry from which liquid has been extracted.
Claim 8
Dependent Claim
37 words

Claim 9
Dependent Claim
26 words
The invention of claim 7 wherein the spin-drying drum axis is inclined downwardly at an angle of about 15° to 30° to the washing drum axis.
Claim 10
Dependent Claim
25 words
The invention of claim 7, wherein the spin-drying drum axis is inclined downwardly at angle of inclination of about 20° to the washing drum axis.
