Abstract
Abstract A laundry additive dispenser for use with laundry appliances has a tiltable bin pivotally mounted for user access on a panel of the laundry appliance. The bin is divided into three sections which are exposed when the bin is tilted forward to a receiving position and may be filled with liquid or granular laundry additives. The bin is then tilted back to a dispensing position. The sections of the bin for dispensing liquid laundry additives each have a siphon therein. Solenoid operated valves selectively communicate each section with a water distribution path. When an appropriate valve is opened water flows in the proper section of the bin and when the water-additive solution reaches an appropriate level, siphoning action begins and the entire contents of the section is dispensed to a clothes treatment zone in the appliance. Each section is provided with an overflow tube to insure that the liquid level in the section does not reach a level so as to prevent the siphoning action.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
In an automatic washer having a tub for receiving a clothes load to be washed and a water supply for delivering water to said tub, a dispenser for delivering an additive to said tub, said dispenser comprising: a container for receiving and dispensing said additive; a mounting means for pivotally supporting said container for movement between a receiving position and a dispensing position; at least one siphon within said container communicating with said tub for siphoning a liquid from said container to said tub whenever said liquid rises above a dispensing level in said container; an overflow tube within said container, said overflow tube movable with said container to said receiving position and when in said receiving position, effective to prevent filling said container to said dispensing level, said overflow tube movable with said container to said dispensing position and when in said dispensing position, effective to allow said liquid to rise above said dispensing level; and a valve means for directing a portion of said water supply to said container for mixing with said additive to raise the liquid level within said container above said dispensing level.
Claim 2
Dependent Claim
188 words
In an automatic washer having a tub for receiving a clothes load to be washed and a water supply for delivering water to said tub, a dispenser for delivering an additive to said tub, said dispenser comprising: a container for receiving and dispensing said additive; a mounting means for pivotally supporting said container for movement between a receiving position and a dispensing position; at least one siphon within said container communicating with said tub for siphoning a liquid from said container to said tub whenever said liquid rises above a dispensing level in said container; an overflow tube within said container, said overflow tube movable with said container to said receiving position and when in said receiving position, effective to prevent filling said container to said dispensing level, said overflow tube movable with said container to said dispensing position and when in said dispensing position, effective to allow said liquid to rise above said dispensing level; and a valve means for directing a portion of said water supply to said container for mixing with said additive to raise the liquid level within said container above said dispensing level.
Claim 3
Dependent Claim
26 words
The dispenser of claim 1 wherein said container is divided into a plurality of noncommunicating compartments for receiving a plurality of different additives in respective compartments.
Claim 4
Dependent Claim
51 words
The dispenser of claim 1 wherein said container is divided into three noncommunicating compartments and wherein two of said compartments contain a siphon for dispensing liquid additive and wherein one of said compartments has an opening in a bottom thereof for dispensing a mixture of said water and a granular additive.
Claim 5
Dependent Claim
67 words
The dispenser of claim 3 wherein said valve means directs a portion of said water supply simultaneously to one of said compartments containing a siphon and said granular additive dispensing compartment at a first time in a cycle of operation, and directs a portion of said inlet water supply to the other of said compartments containing a siphon at a second time in said cycle of operation.
Claim 6
Dependent Claim
16 words
The dispenser of claim 1 wherein said valve means comprises at least one solenoid-controlled diaphragm valve.
Claim 7
Dependent Claim
68 words
The dispenser of claim 1 wherein said automatic washer has a cabinet having vertical walls, said mounting means is disposed in one of said vertical walls and said container has a front face, wherein said container is in said receiving position when said front face is in a tilted position with said container front face forming an angle with the wall in which said mounting means is disposed.
Claim 8
Dependent Claim
61 words
The dispenser of claim 1 wherein said automatic washer has a cabinet having vertical walls, said mounting means is disposed in one of said vertical walls, and said container has a front face, wherein said container is in said dispensing position when said front face of said container is coplanar with the vertical wall in which said mounting means is disposed.
Claim 9
Dependent Claim
180 words
In an automatic washer appliance having a treatment zone operable through a programmed sequence of washing, rinsing and drying steps, additive dispensing means in said appliance comprising a container adapted to be filed to selective levels, mounting means carrying said container for pivotal movement between a first receiving position and a second dispensing position, whereby the container may be charged with additive in said receiving position, siphon means in said container for siphoning liquid out of said container and into a treatment zone in response to the liquid in the container reaching a specified level, means for preventing said liquid from reaching said specified level when said container is in said first receiving position, and water control means for selectively providing water to said container and operable in correlation with the programmed sequence, whereby the container may be prefilled to a first selected level with additive and thereafter will be automatically filled to said specified level with water as a function of the programmed sequence of the machine whereupon the additive and water will be siphoned into the treatment zone.
Claim 10
Dependent Claim
180 words
In an automatic washer appliance having a treatment zone operable through a programmed sequence of washing, rinsing and drying steps, additive dispensing means in said appliance comprising a container adapted to be filed to selective levels, mounting means carrying said container for pivotal movement between a first receiving position and a second dispensing position, whereby the container may be charged with additive in said receiving position, siphon means in said container for siphoning liquid out of said container and into a treatment zone in response to the liquid in the container reaching a specified level, means for preventing said liquid from reaching said specified level when said container is in said first receiving position, and water control means for selectively providing water to said container and operable in correlation with the programmed sequence, whereby the container may be prefilled to a first selected level with additive and thereafter will be automatically filled to said specified level with water as a function of the programmed sequence of the machine whereupon the additive and water will be siphoned into the treatment zone.
Claim 11
Dependent Claim
152 words
For use with a domestic cleaning appliance having a treatment zone, an additive dispenser having a tiltable bin pivotally mounted for user access and partitioned to provide plural compartments for plural additives, presettable sequential control means including water control means actuable during the course of a programmed sequence of washing, rinsing and drying steps to direct a flow of water into at least one of said compartments in selected program sequence, a siphon means contained within at least one of said compartments for siphoning liquid from said compartments, each said siphon means being responsive to attainment of a dispensing water level in said compartment to automatically siphon the additive and water contents of such compartment into said treatment zone, and an overflow tube contained within each of said plurality of compartments to prevent a siphoning action by said siphoning means before said control means directs said flow of water into said compartment.
