Dispensing treating chemistry in a laundry treating appliance
A method of operating a laundry treating appliance having a treating chamber for receiving laundry for treatment and a dispensing system for dispensing treating chemistry for use in treating the laundry comprises, determining an amount of laundry in the treating chamber, setting at least one of a dilution and a delivery rate for the treating chemistry based on the determined amount of laundry to define a dispensing parameter and controlling the dispensing system to dispense the treating chemistry according to the dispensing parameter.
1. A method of operating a laundry treating appliance having a treating chamber for receiving laundry for treatment and a dispensing system having a dispensing pump for dispensing a treating chemistry for use in treating the laundry, the method comprising:
determining an amount of laundry in the treating chamber;
determining a dispensing parameter based on the determined amount of laundry; and
wherein the dispensing parameter is defined by one or more of a delivery rate of the treating chemistry, a dilution rate of the treating chemistry, a flow rate of a water supply, a flow rate of a dispensing pump, and a length of a dispensing interval.
2. The method of claim 1 , further comprising supplying water to the treating chamber and supplying the treating chemistry into the supplied water according to the dispensing parameter.
3. The method of claim 1 wherein the dispensing parameter is the dilution rate of the treating chemistry.
4. The method of claim 1 wherein the dispensing parameter is the delivery rate of the treating chemistry.
5. The method of claim 4 , further comprising supplying water and where the treating chemistry is delivered at the delivery rate for a duration of the supplying of water.
6. The method of claim 5 wherein the supplying water comprises supplying a predetermined amount of water.
7. The method of claim 5 wherein the delivery rate is constant for the duration of the supplying of water.
8. The method of claim 5 wherein the treating chemistry is delivered intermittently at an at least one intermittent delivery rate for the duration of the supplying of water.
9. The method of claim 8 wherein the at least one intermittent delivery rate is equal to the delivery rate.
10. The method of claim 9 wherein the treating chemistry is delivered at the at least one intermittent delivery rate two or more times and an average of the intermittent delivery rates is equal to the delivery rate.
11. The method of claim 1 wherein the dispensing parameter is set such that a rate of deposition of the treating chemistry on the laundry is approximately 0.75 ml treating chemistry/L of water to 10 ml treating chemistry/L of water.
12. The method of claim 1 wherein the dispensing the treating chemistry comprises supplying the treating chemistry into a mixing chamber.
13. The method of claim 1 wherein the dispensing the treating chemistry comprises supplying the treating chemistry into a flow of water.
14. The method of claim 13 further comprising determining a flow rate of the flow of water and the dispensing parameter is based on the determined flow rate of water.
15. The method of claim 1 further comprising supplying water to sufficiently saturate the laundry and delivering the treating chemistry at the delivery rate for the duration of an additional supply of water.
