Abstract

Abstract Improved water dispersing apparatus for dispersing water about the area of the upper rack of a dishwasher, the apparatus including a rotatable member which is of inverted, generally conical shape, different segments of the lower surface of the member having different slopes to deflect the upwardly directed stream of water at different angles depending upon which of the surfaces the stream impinges upon, the member also including segments open from the periphery to the hub to permit part of the water to pass directly upwardly therethrough.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 212 words
In dishwasher apparatus having an enclosed washing chamber and upper and lower open racks in the chamber for supporting articles to be washed, and having means for directing a part of the washing water against the lower rack and for directing another part of the washing water upwardly to rotate water dispersing means located generally centrally and below said upper rack and against which said stream of water is directed, the improvement in which the water dispersing means comprises: an inverted, generally conically-shaped member having a central hub about which said member is rotatable and having water deflecting lower surfaces sloping upwardly and outwardly from said hub to the peripheral rim portion of said member; said lower surfaces being formed of and divided into at least two sets of generally pie-shaped segments, the individual segments of one of said sets having a steeper slope than the other of said sets and therefore terminating at the upper face of said member in a rim portion spaced radially inwardly from the rim portion formed at the upper face by the individual segments of the other of said sets; and at least one open segment extending inwardly to the hub from the outer periphery of said member for permitting water to pass directly upwardly therethrough.
Claim 2
Dependent Claim 212 words
In dishwasher apparatus having an enclosed washing chamber and upper and lower open racks in the chamber for supporting articles to be washed, and having means for directing a part of the washing water against the lower rack and for directing another part of the washing water upwardly to rotate water dispersing means located generally centrally and below said upper rack and against which said stream of water is directed, the improvement in which the water dispersing means comprises: an inverted, generally conically-shaped member having a central hub about which said member is rotatable and having water deflecting lower surfaces sloping upwardly and outwardly from said hub to the peripheral rim portion of said member; said lower surfaces being formed of and divided into at least two sets of generally pie-shaped segments, the individual segments of one of said sets having a steeper slope than the other of said sets and therefore terminating at the upper face of said member in a rim portion spaced radially inwardly from the rim portion formed at the upper face by the individual segments of the other of said sets; and at least one open segment extending inwardly to the hub from the outer periphery of said member for permitting water to pass directly upwardly therethrough.
Claim 3
Dependent Claim 27 words
In dishwashing apparatus according to claim 1 including a vane projecting away from the face of one of said segments of said other set of said segments.
Claim 4
Dependent Claim 48 words
In dishwashing apparatus according to claim 1 said individual segments of said one set are bounded on opposite sides by segments of said other set to form a section of said member, and each said section is separated from an adjacent section by one of said open segments.
Claim 5
Dependent Claim 137 words
A water dispersal member for dispersing water directed against its underside about the upper portion of the dishwasher, said water dispersal member comprising an inverted, generally conically-shaped member having a central hub about which said member is rotatable by the force of water directed against said member, said member including water deflecting lower surfaces sloping upwardly and outwardly from said hub to the upper rim portion of said member, said lower surface being formed of and divided into discrete, generally pie-shaped segments, some of said segments having a steeper slope than others of said segments and having rim portions spaced inwardly from the rim portions of the others and said segments, and a number of open segments extending inwardly to the hub from the rim portion of said member for permitting water to pass directly upwardly therethrough.
Claim 6
Dependent Claim 137 words
A water dispersal member for dispersing water directed against its underside about the upper portion of the dishwasher, said water dispersal member comprising an inverted, generally conically-shaped member having a central hub about which said member is rotatable by the force of water directed against said member, said member including water deflecting lower surfaces sloping upwardly and outwardly from said hub to the upper rim portion of said member, said lower surface being formed of and divided into discrete, generally pie-shaped segments, some of said segments having a steeper slope than others of said segments and having rim portions spaced inwardly from the rim portions of the others and said segments, and a number of open segments extending inwardly to the hub from the rim portion of said member for permitting water to pass directly upwardly therethrough.
