Abstract

A method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.

First claim

What is claimed is:

1. A laundry treating appliance, comprising:
a laundry treating chamber;
a bulk treating chemistry dispenser configured to hold multiple doses of treating chemistry for dispensing into the laundry treating chamber;
a user interface configured to provide an indication to the user;
a sensor adjacent to the bulk treating chemistry dispenser and where the sensor is configured to sense at least one of a presence of the treating chemistry, a presence of the bulk treating chemistry dispenser, a fill level of the treating chemistry in the bulk treating chemistry dispenser, or a volume of the treating chemistry in the bulk treating chemistry dispenser and provide an output signal indicative thereof; and
a controller coupled with the user interface, the sensor, and the bulk treating chemistry dispenser and configured to execute an operating cycle, the controller configured to determine an amount of treating chemistry an amount of treating chemistry remaining in the bulk treating chemistry dispenser based on the output signal, and the controller configured to control the user interface such that the user interface provides an indication of the determined amount of treating chemistry remaining in the bulk treating chemistry dispenser as the amount of treating chemistry is reduced.

2. The laundry treating appliance of claim 1 wherein the controller is configured to determine the amount of treating chemistry remaining in the bulk treating chemistry dispenser based at least on the sensed presence of the treating chemistry or the sensed presence of the bulk treating chemistry dispenser.

3. The laundry treating appliance of claim 2 wherein the controller is further configured to determine the amount of treating chemistry by decrementing a predetermined number of doses for each executed cycle.

4. The laundry treating appliance of claim 3 wherein a treating chemistry meter for the bulk treating chemistry dispenser provides historical usage data to the controller for each of the executed cycles.

5. The laundry treating appliance of claim 1 wherein the user interface provides an indication of an amount of treating chemistry remaining in the bulk treating chemistry dispenser as the amount of treating chemistry is reduced from a filled dispenser to that of an emptied dispenser.

6. The laundry treating appliance of claim 1 wherein the controller is further configured to determine that there is an insufficient amount of treating chemistry present in the bulk treating chemistry dispenser for a selected cycle.

7. The laundry treating appliance of claim 6 wherein the controller is further configured to effect the dispensing of entire contents of the bulk treating chemistry dispenser when it is determined that there is an insufficient amount of treating chemistry.

8. The laundry treating appliance of claim 7 wherein the controller is further configured to control the user interface such that the user interface provides an indication of the determined insufficient amount.

9. The laundry treating appliance of claim 6 wherein the controller is configured to control the user interface such that the user interface provides an indication of the determined insufficient amount.

10. A laundry treating appliance, comprising:
a laundry treating chamber;
a bulk treating chemistry dispenser configured to hold multiple doses of treating chemistry for dispensing into the laundry treating chamber;
a user interface configured to provide an indication to the user;
a sensor configured to sense a fill level of the treating chemistry in the bulk treating chemistry dispenser and provide a signal indicative of the fill level; and
a controller coupled with the user interface, the sensor, and the bulk treating chemistry dispenser and configured to execute an operating cycle and to control the user interface such that the user interface provides an indication of an amount of treating chemistry remaining in the bulk treating chemistry dispenser as the amount of treating chemistry is reduced.

11. A laundry treating appliance, comprising:
a laundry treating chamber;
a bulk treating chemistry dispenser configured to hold multiple doses of treating chemistry for dispensing into the laundry treating chamber;
a user interface configured to provide an indication to the user;
a sensor configured to sense a volume of the treating chemistry in the bulk treating chemistry dispenser and provide a signal indicative of the volume; and
a controller coupled with the user interface, the sensor, and the bulk treating chemistry dispenser and configured to execute an operating cycle and to control the user interface such that the user interface provides an indication of an amount of treating chemistry remaining in the bulk treating chemistry dispenser as the amount of treating chemistry is reduced.

12. The laundry treating appliance of claim 11 wherein the controller is further configured to control execution of the operating cycle based on the signal.

13. The laundry treating appliance of claim 12 wherein the controller is further configured to cease executing the operating cycle based on the signal.

14. The laundry treating appliance of claim 11 wherein the user interface provides an indication of the volume remaining in the bulk treating chemistry dispenser.

15. The laundry treating appliance of claim 14 wherein the user interface provides a volumetric numerical value of the volume remaining in the bulk treating chemistry dispenser.

16. The laundry treating appliance of claim 14 wherein the user interface provides an iconic representation of the volume remaining in the bulk treating chemistry dispenser.

17. The laundry treating appliance of claim 16 wherein the iconic representation of the volume remaining in the bulk treating chemistry dispenser is at least one of an icon, an alpha-numeric reading, a bar reading to be proportionally illuminated, or a stack of lights to be proportionally illuminated.

18. The laundry treating appliance of claim 11 wherein the signal to the controller indicative of the volume comprises a signal indicative of a percentage of the total volume of the bulk treating chemistry dispenser.

19. The laundry treating appliance of claim 18 wherein the controller is further configured to determine a remaining volume of treating chemistry present in the bulk treating chemistry dispenser based on the signal indicative of the percentage of the total volume of the bulk treating chemistry dispenser.
