Abstract

A method may include detecting one or more insertion actions for a loading one or more articles into the dishwashing appliance and directing, subsequent to the detected insertion actions, a dishwasher cycle within the dishwashing appliance. The method may also include detecting, subsequent to the dishwasher cycle, one or more removal actions for unloading the one or more articles from the dishwashing appliance. The method may further include evaluating the detected removal actions against the detected insertion actions and directing a user interface of the dishwashing appliance based on the evaluation.

Claims (49)

1. A method of operating a dishwashing appliance comprising:

detecting one or more insertion actions for a loading one or more articles into the dishwashing appliance;

directing, subsequent to the detected insertion actions, a dishwasher cycle within the dishwashing appliance;

detecting, subsequent to the dishwasher cycle, one or more removal actions for unloading the one or more articles from the dishwashing appliance;

evaluating the detected removal actions against the detected insertion actions; and

directing a user interface of the dishwashing appliance based on the evaluation;

transmitting, prior to detecting one or more removal actions and subsequent to the dishwasher cycle, a monitoring request to one or more connected domestic appliances spaced apart from the dishwashing appliance; and

receiving a monitoring signal from the one or more connected domestic appliances in response to transmitting the monitoring request,

wherein detecting one or more removal actions is based on the received monitoring signal,

wherein detecting one or more insertion actions comprises receiving a captured image from a camera assembly in operable communication with the dishwashing appliance,

wherein the camera assembly is fixed to a corresponding domestic appliance of the one or more connected domestic appliances spaced apart from the dishwashing appliance, and

wherein the camera assembly is directed away from the corresponding domestic appliance.

2. The method of claim 1 , further comprising detecting a door-open event subsequent to the dishwasher cycle,

wherein detecting one or more removal actions is partially conditioned on detecting the door-open event.

3. The method of claim 1 , wherein detecting one or more insertion actions comprises analyzing the captured image according to a trained AI model.

4. The method of claim 1 , further comprising initiating a clean load indication at the user interface subsequent to the dishwasher cycle;

wherein evaluating comprises determining the detected removal actions meets a predetermined matching condition based on the detected insertion actions, and

wherein directing the user interface comprises halting the clean load indication in response to determining the detected removal actions meets the predetermined matching condition.

5. The method of claim 1 , further comprising initiating a clean load indication at the user interface subsequent to the dishwasher cycle;

wherein evaluating comprises determining the detected removal actions fails a predetermined matching condition based on the detected insertion actions, and

wherein directing the user interface comprises maintaining the clean load indication in response to determining the detected removal actions fails the predetermined matching condition.

6. The method of claim 1 , wherein evaluating comprises determining the detected removal actions fails a predetermined matching condition based on the detected insertion actions,

wherein the method further comprises detecting a new insertion action subsequent to determining the detected removal actions fails the predetermined matching condition, and

wherein directing the user interface comprises initiating an improper loading indication in response to detecting the new insertion action.

7. A method of operating a dishwashing appliance comprising:

detecting, apart from the dishwashing appliance, one or more insertion actions for a loading one or more articles into the dishwashing appliance;

directing, subsequent to the detected insertion actions, a dishwasher cycle within the dishwashing appliance;

detecting, apart from the dishwashing appliance and subsequent to the dishwasher cycle, one or more removal actions for unloading the one or more articles from the dishwashing appliance;

evaluating the detected removal actions against the detected insertion actions;

determining a load status of the dishwashing appliance based on the evaluation; and

directing a user interface of the dishwashing appliance based on the determined load status;

transmitting, prior to detecting one or more removal actions and subsequent to the dishwasher cycle, a monitoring request to one or more connected domestic appliances spaced apart from the dishwashing appliance; and

receiving a monitoring signal from the one or more connected domestic appliances in response to transmitting the monitoring request,

wherein detecting one or more removal actions is based on the received monitoring signal,

wherein detecting one or more insertion actions comprises receiving a captured image from a camera assembly in operable communication with the dishwashing appliance,

wherein the camera assembly is fixed to a corresponding domestic appliance of the one or more connected domestic appliances spaced apart from the dishwashing appliance, and

wherein the camera assembly is directed away from the corresponding domestic appliance.

8. The method of claim 7 , further comprising detecting a door-open event subsequent to the dishwasher cycle,

wherein detecting one or more removal actions is partially conditioned on detecting the door-open event.

9. The method of claim 7 , wherein detecting one or more insertion actions comprises analyzing the captured image according to a trained AI model.

10. The method of claim 7 , further comprising initiating a clean load indication at the user interface subsequent to the dishwasher cycle;

wherein evaluating comprises determining the detected removal actions meets a predetermined matching condition based on the detected insertion actions, and

wherein directing the user interface comprises halting the clean load indication in response to determining the detected removal actions meets the predetermined matching condition.

11. The method of claim 7 , further comprising initiating a clean load indication at the user interface subsequent to the dishwasher cycle;

wherein evaluating comprises determining the detected removal actions fails a predetermined matching condition based on the detected insertion actions, and

wherein directing the user interface comprises maintaining the clean load indication in response to determining the detected removal actions fails the predetermined matching condition.

12. The method of claim 7 , wherein evaluating comprises determining the detected removal actions fails a predetermined matching condition based on the detected insertion actions,

wherein the method further comprises detecting a new insertion action subsequent to determining the detected removal actions fails the predetermined matching condition, and

wherein directing the user interface comprises initiating an improper loading indication in response to detecting the new insertion action.
