Abstract

A method of operating a washing machine appliance includes filling a wash tub with a wash liquid during a first cycle. The method also includes receiving a pause input after filling the wash tub and before draining the wash tub during the first cycle. In response to the pause input, the first cycle is paused for a pause duration. The method further includes incrementing a pause counter in response to the pause input and storing the pause duration after pausing the first cycle. The method also includes filling the wash tub with a wash liquid during a second cycle after the first cycle and automatically pausing the second cycle after filling the wash tub with the wash liquid during the second cycle, based on the pause counter and the stored pause duration.

First claim

What is claimed is:

1. A method of operating a washing machine appliance, the washing machine appliance comprising a cabinet and a wash tub mounted within the cabinet, the wash tub configured for containing fluid during operation of the washing machine appliance, the method comprising:
filling the wash tub with a wash liquid during a first cycle of the washing machine appliance;
receiving a pause input from a user interface of the washing machine appliance after filling the wash tub with the wash liquid during the first cycle and before draining the wash liquid from the wash tub during the first cycle;
pausing the first cycle of the washing machine appliance for a pause duration in response to the pause input;
resuming the first cycle of the washing machine at the end of the pause duration;
incrementing a pause counter in response to the pause input;
storing the pause duration after resuming the first cycle of the washing machine appliance;
filling the wash tub with a wash liquid during a second cycle of the washing machine appliance after the first cycle; and
automatically pausing the second cycle of the washing machine appliance after filling the wash tub with the wash liquid during the second cycle, based on the pause counter and the stored pause duration.

2. The method of claim 1 , wherein the second cycle of the washing machine appliance is automatically paused when the pause counter is greater than a threshold value.

3. The method of claim 1 , wherein the second cycle of the washing machine appliance is automatically paused for a default pause duration.

4. The method of claim 1 , further comprising one or more intermediate cycles between the first cycle and the second cycle, receiving a pause input after filling the wash tub with a wash liquid during each of the one or more intermediate cycles and before draining the wash liquid from the wash tub during each of the one or more intermediate cycles, pausing each of the one or more intermediate cycles of the washing machine appliance for a respective pause duration in response to each respective pause input, and calculating an average pause duration from the pause duration of the first cycle and each respective pause duration of the one or more intermediate cycles, wherein the second cycle of the washing machine appliance is automatically paused for the average pause duration.

5. The method of claim 1 , further comprising recording a cycle type of the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a cycle type of the second cycle is the same as the cycle type of the first cycle.

6. The method of claim 1 , further comprising recording a soil level selection of the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a soil level selection of the second cycle is the same as the soil level selection of the first cycle.

7. The method of claim 1 , further comprising recording a temperature selection of the wash liquid during the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a temperature selection for the second cycle is the same as the recorded temperature selection from the first cycle.

8. The method of claim 1 , further comprising recording a turbidity level during the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a turbidity level during the second cycle is the same as the recorded turbidity level from the first cycle.

9. The method of claim 1 , further comprising recording one or more conditions of the first cycle, wherein the pause counter is a first pause counter corresponding to the one or more recorded conditions of the first cycle and the one or more recorded conditions of the first cycle are present in the second cycle, further comprising incrementing a second pause counter in response to receiving a pause input during a third cycle of the washing machine appliance, wherein the one or more recorded conditions of the first cycle are not present in the third cycle.

10. The method of claim 1 , further comprising providing a prompt to add a soak time on the user interface of the washing machine appliance based on the pause counter and the stored pause duration prior to the second cycle of the washing machine appliance, wherein the second cycle of the washing machine appliance is automatically paused after receiving an affirmative response to the prompt.

11. A washing machine appliance comprising:
a cabinet;
a wash tub mounted within the cabinet, the wash tub configured for containing fluid during operation of the washing machine appliance; and
a controller, the controller configured for:
filling the wash tub with a wash liquid during a first cycle of the washing machine appliance;
receiving a pause input from a user interface of the washing machine appliance after filling the wash tub with the wash liquid during the first cycle and before draining the wash liquid from the wash tub during the first cycle;
pausing the first cycle of the washing machine appliance for a pause duration in response to the pause input;
resuming the first cycle of the washing machine at the end of the pause duration;
incrementing a pause counter in response to the pause input;
storing the pause duration after resuming the first cycle of the washing machine appliance;
filling the wash tub with a wash liquid during a second cycle of the washing machine appliance after the first cycle; and
automatically pausing the second cycle of the washing machine appliance based on the pause counter and the stored pause duration.

12. The washing machine appliance of claim 11 , wherein the controller is configured for automatically pausing the second cycle of the washing machine appliance when the pause counter is greater than a threshold value.

13. The washing machine appliance of claim 11 , wherein the controller is configured for automatically pausing the second cycle of the washing machine appliance for a default pause duration.

14. The washing machine appliance of claim 11 , wherein the controller is further configured for performing one or more intermediate cycles between the first cycle and the second cycle, receiving a pause input after filling the wash tub with a wash liquid during each of the one or more intermediate cycles and before draining the wash liquid from the wash tub during each of the one or more intermediate cycles, pausing each of the one or more intermediate cycles of the washing machine appliance for a respective pause duration in response to each respective pause input, and calculating an average pause duration from the pause duration of the first cycle and each respective pause duration of the one or more intermediate cycles, wherein the second cycle of the washing machine appliance is automatically paused for the average pause duration.

15. The washing machine appliance of claim 11 , wherein the controller is further configured for recording a cycle type of the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a cycle type of the second cycle is the same as the cycle type of the first cycle.

16. The washing machine appliance of claim 11 , wherein the controller is further configured for recording a soil level selection of the first cycle, wherein the step of automatically pausing the second cycle of the washing machine appliance is performed when a soil level selection of the sec
