Abstract

A laundry treating appliance having a treating chamber and a bulk dispenser and a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and a controller coupled with the user interface and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense the predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser and 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.

Claims (24)

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 treating chemistry meter configured to dispense a predetermined amount of treating chemistry from the bulk treating chemistry dispenser;

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 operably coupled with the sensor and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense a predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser based on information received from the sensor and the treating chemistry meter.

2. The laundry treating appliance of claim 1 wherein the predetermined amount of treating chemistry set to be dispensed by the controller varies from operating cycle to operating cycle.

3. The laundry treating appliance of claim 1 wherein the predetermined amount of treating chemistry set to be dispensed by the controller varies for a same type of operating cycle.

4. The laundry treating appliance of claim 1 , further comprising a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and wherein the treating chemistry meter is operably coupled to the user interface and is configured to send a signal to the user interface indicative of the amount of treating chemistry available or used.

5. The laundry treating appliance of claim 1 , further comprising a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and wherein the controller is configured to control the user interface such that the indication on the user interface relates to the determined number of doses of treating chemistry available in the bulk treating chemistry dispenser.

6. The laundry treating appliance of claim 5 wherein the indication of the number of doses of treating chemistry available in the bulk treating chemistry dispenser is an indication of a number of doses of treating chemistry remaining in the bulk treating chemistry dispenser, each dose being an average dose size.

7. The laundry treating appliance of claim 6 wherein the controller is further configured to determine the average dose size based on information output from the treating chemistry meter.

8. The laundry treating appliance of claim 7 wherein the controller is further configured to determine the average dose size from a running average of dispensed doses over a predetermined number of recent cycles.

9. The laundry treating appliance of claim 7 wherein the controller is further configured to determine the amount of treating chemistry remaining in the bulk treating chemistry dispenser based at least on a sensed presence of the treating chemistry and configured to determine the amount of treating chemistry by decrementing a predetermined number of doses for each executed cycle.

10. The laundry treating appliance of claim 1 wherein the controller is further configured to determine the number of doses of treating chemistry available in the bulk treating chemistry dispenser by dividing the sensed remaining treating chemistry by a reference dose size.

11. The laundry treating appliance of claim 10 wherein the treating chemistry meter provides historical usage data to the controller to define the reference dose size.

12. The laundry treating appliance of claim 1 wherein the controller is further configured to control execution of the operating cycle based on the number of doses of treating chemistry available in the bulk treating chemistry dispenser.

13. The laundry treating appliance of claim 12 wherein the controller is further configured to cease executing the operating cycle based on the number of doses of treating chemistry available in the bulk treating chemistry dispenser.

14. The laundry treating appliance of claim 1 , further comprising a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and wherein the user interface provides an indication of the determined number of doses of treating chemistry available in the bulk treating chemistry dispenser.

15. The laundry treating appliance of claim 14 wherein the user interface provides an iconic representation of the number of doses of treating chemistry available in the bulk treating chemistry dispenser.

16. The laundry treating appliance of claim 15 wherein the iconic representation of the number of doses of treating chemistry available 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.

17. 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.

18. The laundry treating appliance of claim 17 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.

19. The laundry treating appliance of claim 18 , further comprising a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and wherein the controller is further configured to control the user interface such that the user interface provides an indication of the determined insufficient amount.
