Abstract

A laundry washing machine and method automate the selection of one or more parameters of a wash cycle of a laundry washing machine based in part on a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of one or more items added to the wash tub and a weight sensor operatively coupled to the wash tub, where the weight sensor is configured to detect the addition of an item among the one or more items to the wash tub and initiate capturing of the color composition data, and a controller is configured to configure one or more parameters for a wash cycle based upon the captured color composition data.

First claim

What is claimed is:

1. A laundry washing machine, comprising:
a wash tub disposed within a housing;
a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of one or more items added to the wash tub;
a retractable cover configured to selectively cover the color detection sensor;
a weight sensor operatively coupled to the wash tub; and
a controller coupled to the color detection sensor, the retractable cover, and the weight sensor and configured to detect an addition of an item among the one or more items to the wash tub with the weight sensor, initiate automatic retraction of the retractable cover in response to opening of a door that covers the opening of the wash tub, and initiate capturing of the color composition data with the color detection sensor responsive thereto,
wherein the controller is further configured to configure one or more parameters for a wash cycle based upon the captured color composition data.

2. The laundry washing machine of claim 1 , wherein the color detection sensor comprises an image sensor configured to capture an image in response to changes in weight sensed by the weight sensor as additional items are added to the wash tub.

3. The laundry washing machine of claim 1 , wherein the color detection sensor comprises an image sensor, and wherein the controller is configured to cause the image sensor to sequentially capture a plurality of images in response to changes in weight sensed by the weight sensor as additional items are added to the wash tub.

4. The laundry washing machine of claim 1 , wherein the controller is further configured to trigger automatic closing of the retractable cover in response to closing of the door.

5. The laundry washing machine of claim 1 , wherein the captured color composition data includes one or more images, and wherein the controller is further configured to detect a stain on an item among the one or more items added to the wash tub from the one or more images.

6. The laundry washing machine of claim 5 , wherein the controller is further configured to generate a recommendation to use a stain removal tool and communicate the recommendation to a user via a user interface or a mobile computing device in response to detecting the stain.

7. The laundry washing machine of claim 5 , wherein the controller is further configured to configure one or more parameters for the wash cycle in response to detecting the stain.

8. The laundry washing machine of claim 5 , wherein the controller is further configured to identify one or more characteristics of the stain detected and configure one or more parameters for the wash cycle in response to the identified one or more characteristics.

9. The laundry washing machine of claim 1 , wherein the controller is configured to select a load type from among a plurality of load types based upon the captured color composition data, and wherein the controller is configured to configure the one or more parameters for the wash cycle based upon the selected load type.

10. The laundry washing machine of claim 1 , wherein the one or more parameters include a wash or rinse temperature, a wash or rinse water amount, an agitation duration, an agitation stroke, a soak duration, a spin speed, a spin duration, a cycle time, or a number of phase repeats.

11. A laundry washing machine, comprising:
a wash tub disposed within a housing;
a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of an item added to the wash tub;
a retractable cover configured to selectively cover the color detection sensor;
a weight sensor operatively coupled to the wash tub; and
a controller coupled to the color detection sensor, the retractable cover, and the weight sensor and configured to detect a stain on the item added to the wash tub by detecting addition of the item to the wash tub with the weight sensor, initiating automatic retraction of the retractable cover in response to opening of a door that covers the opening of the wash tub, initiating capturing of the color composition data of the item added to the wash tub responsive to detecting the addition of the item to the wash tub with the weight sensor, and detecting the stain based upon the captured color composition data,
wherein the controller is configured to configure one or more parameters for a wash cycle based on the stain detected.

12. The laundry washing machine of claim 11 , wherein the controller is configured to identify one or more characteristics of the stain sensed by the color detection sensor.

13. The laundry washing machine of claim 12 , wherein the controller is further configured to generate a recommendation to use a stain removal tool and communicate the recommendation to a user via a user interface or a mobile computing device based on the one or more characteristics of the stain sensed by the color detection sensor.

14. The laundry washing machine of claim 11 , wherein the one or more parameters include a wash or rinse temperature, a wash or rinse water amount, an agitation duration, an agitation stroke, a soak duration, a spin speed, a spin duration, a cycle time, or a number of phase repeats.

15. The laundry washing machine of claim 11 , wherein the color detection sensor comprises an image sensor configured to capture an image in response to changes in weight sensed by the weight sensor as additional items are added to the wash tub.

16. The laundry washing machine of claim 11 , wherein the color detection sensor comprises an image sensor, and wherein the controller is configured to cause the image sensor to sequentially capture a plurality of images in response to changes in weight sensed by the weight sensor as additional items are added to the wash tub.

17. A laundry washing machine, comprising:
a wash tub disposed within a housing;
a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of an item added to the wash tub;
a retractable cover configured to selectively cover the color detection sensor; and
a controller coupled to the color detection sensor and the retractable cover configured to initiate automatic retraction of the retractable cover in response to opening of a door that covers an opening of the wash tub and initiate capturing of the color composition data with the color detection sensor,
wherein controller is further configured to configure one or more parameters for a wash cycle based upon the captured color composition data.

18. The laundry washing machine of claim 17 , wherein the controller is configured to initiate automatic closing of the retractable cover in response to closing of the door.
