Abstract

A washer and a control for an automatic washer to operate the washer through a wash cycle selected based upon a range of conditions of a fabric load to be washed. The control has a plurality of selectable stain type entrées, each with a particular dedicated wash cycle. The control also has dispensing control over at least two wash liquor additives, one being a detergent and the other being an oxidizing agent. The control operates the dedicated wash cycles, as selected, using both the detergent and the oxidizing agent, however, the detergent and the oxidizing agent may be dispensed in different orders and at different times and in different amounts, depending on the stain type selected.

Claims (33)

1. A control for an automatic washer to operate the washer through a dedicated wash cycle automatically selected based upon a range of conditions of the fabric load to be washed,

the control having at least one of a control interface and an electronic input to permit the selection of one of a plurality of stain type entrées stored in a memory of the control, each with a particular dedicated wash cycle also stored in the memory of the control,

the control being operatively connected to chambers for at least two wash liquor additives, comprising a detergent and an oxidizing agent, to provide dispensing control for selectively dispensing the detergent and the oxidizing agent during the wash cycle,

the control being operatively connected to control the dedicated wash cycles, as automatically selected, using both the detergent and the oxidizing agent, the dedicated wash cycles stored in the control memory being arranged to cause the dispensing of the detergent and the oxidizing agent in different orders, in different amounts and at different times, depending on the stain type selected.

2. The control according to claim 1 , wherein the stain types include at least one of grass, blood, cocoa, carbon, red wine, tea, coffee perspiration, dirt, mud and oily soils.

3. The control according to claim 1 , wherein the at least one of a control interface and an electronic input permit the selection of water level entrées.

4. The control according to claim 3 , wherein the water level entrées comprise high, low and regular water levels.

5. The control according to claim 1 , wherein the at least one of a control interface and an electronic input permit the selection of recirculation of the wash liquor.

6. The control according to claim 1 , wherein the at least one of a control interface and an electronic input permit the selection of agitation time entrées.

7. The control according to claim 6 , wherein the agitation time entrées comprise short, extended and regular agitation times.

8. The control according to claim 1 , wherein the at least one of a control interface and an electronic input permit the selection of water temperature entrées.

9. The control according to claim 8 , wherein the water temperature entrées comprise hot, warm, cold and any temperature.

10. The control according to claim 1 , wherein the control is arranged to dispense the oxidizing agent either instantaneously in bulk or at a controlled rate.

11. The control according to claim 1 , the control interface comprises a user input for selecting at least one of the stain type entrées.

12. The control according to claim 1 , wherein the electronic input is arranged to receive a signal indicative of at least one of the stain type entrées.

13. An automatic washer for cleaning a load of fabric, comprising:

a wash zone for receiving the load of fabric,

a first chamber for receiving a detergent additive,

a second chamber for receiving an oxidizing agent additive, and

a control arranged to operate the washer through a dedicated wash cycle automatically selected based upon a range of conditions of the fabric load to be washed,

the control having at least one of a control interface and an electronic input to permit the selection of one of a plurality of stain type entrées stored in a memory of the control, each with a particular dedicated wash cycle also stored in the memory of the control,

the control being operatively connected to the first chamber and the second chamber to provide dispensing control for selectively dispensing the detergent and the oxidizing agent during the wash cycle,

the control being operatively connected to control the dedicated wash cycles, as automatically selected, using both the detergent and the oxidizing agent, the dedicated wash cycles stored in the control memory being arranged to cause the dispensing of the detergent and the oxidizing agent in different orders, in different amounts and at different times, depending on the stain type selected.

14. The automatic washer according to claim 13 , wherein the wash zone is located in a rotatable drum.

15. The automatic washer according to claim 13 , wherein the first and second chambers are separate from one another.

16. A control according to claim 1 , further including the control having dispensing control over hot water and cold water inlet valves, and the control having a timer.

17. The control according to claim 16 , wherein the at least one of a control interface and an electronic input permit the selection of water level entrées.

18. The control according to claim 16 , wherein the at least one of a control interface and an electronic input permit the selection of agitation time entrées.

19. The control according to claim 16 , wherein the at least one of a control interface and an electronic input permit the selection of water temperature entrées.

20. A method of controlling an automatic washer stored in a computer readable memory to permit a control for the automatic washer to operate the washer through a dedicated wash cycle automatically selected based upon a range of conditions of the fabric load to be washed, the steps of the method comprising:

receiving one of a plurality of selectable stain type entrées, each entrée having a particular dedicated wash cycle,

exerting dispensing control over at least two wash liquor additives, comprising a detergent and an oxidizing agent,

operating the dedicated wash cycles, as automatically selected, using both the detergent and the oxidizing agent, however, dispensing the detergent and the oxidizing agent in different orders, in different amounts and at different times, depending on the stain type selected.
