Abstract

A laundry folding appliance includes one or more folding panels mechanically coupled to a cabinet and at least partially defining a folding surface for receiving articles of clothing. An actuating assembly selectively pivots the folding panels to fold the articles of clothing and a camera assembly is positioned in view of the folding surface. A controller obtains one or more images using the camera assembly, identifies the laundry articles positioned on the folding surface by analyzing the one or more images using a laundry identification model, determines a folding protocol for folding the laundry article, and operates the actuating assembly to fold the laundry article in accordance with the folding protocol.

First claim

What is claimed is:

1. A laundry folding appliance comprising:
a cabinet;
a fixed plate attached to the cabinet
one or more folding panels rotatably coupled to the fixed plate by one or more hinge mechanisms, the fixed plate and the one or more folding panels at least partially defining a flat folding surface;
an actuating assembly for selectively folding the one or more folding panels;
a camera assembly positioned in view of the flat folding surface; and
a controller operably coupled to the actuating assembly and the camera assembly, the controller being configured to:
obtain one or more images using the camera assembly;
identify a laundry article positioned on the flat folding surface by analyzing the one or more images using a laundry identification model;
determine a folding protocol for folding the laundry article; and
operate the actuating assembly to fold the laundry article in accordance with the folding protocol.

2. The laundry folding appliance of claim 1 , wherein the actuating assembly comprises:
a plurality of drive motors, each of the plurality of drive motors being mechanically coupled to one of the one or more folding panels for independently moving the one or more folding panels between a lowered position and a raised position.

3. The laundry folding appliance of claim 1 , wherein the laundry identification model analyzes the one or more images using a machine learning image recognition process to identify the laundry article.

4. The laundry folding appliance of claim 3 , wherein the machine learning image recognition process comprises at least one of a convolution neural network (“CNN”), a region-based convolution neural network (“R-CNN”), a deep belief network (“DBN”), or a deep neural network (“DNN”) image recognition process.

5. The laundry folding appliance of claim 3 , wherein the machine learning image recognition process comprises at least one of image classification, image segmentation, key point detection, or feature extraction.

6. The laundry folding appliance of claim 1 , wherein the folding protocol comprises a sequence of pivoting actions of the one or more folding panels as actuated by the actuating assembly.

7. The laundry folding appliance of claim 6 , wherein the folding protocol for pants comprises:
actuating a left panel of the one or more folding panels; and
actuating a right panel of the one or more folding panels.

8. The laundry folding appliance of claim 6 , wherein the folding protocol for shirts comprises:
actuating a left panel of the one or more folding panels;
actuating a right panel of the one or more folding panels; and
actuating a bottom panel of the one or more folding panels.

9. The laundry folding appliance of claim 1 , further comprising:
an attachment mechanism for attaching the laundry article to the flat folding surface.

10. The laundry folding appliance of claim 9 , wherein the attachment mechanism is a mechanical clip.

11. The laundry folding appliance of claim 1 , wherein the camera assembly comprises a camera mounted above the flat folding surface along a vertical direction.

12. The laundry folding appliance of claim 1 , further comprising:
a user interface panel, wherein the folding protocol is selected through the user interface panel.

13. A method of operating a laundry folding appliance, the laundry folding appliance comprising one or more folding panels rotatably coupled to a fixed plate by one or more hinge mechanisms, the fixed plate and the one or more folding panels at least partially defining a flat folding surface, an actuating assembly for selectively folding the one or more folding panels, and a camera assembly positioned in view of the flat folding surface, the method comprising:
obtaining one or more images using the camera assembly;
identifying a laundry article positioned on the flat folding surface by analyzing the one or more images using a laundry identification model;
determining a folding protocol for folding the laundry article; and
operating the actuating assembly to fold the laundry article in accordance with the folding protocol.

14. The method of claim 13 , wherein the laundry identification model analyzes the one or more images using a machine learning image recognition process to identify the laundry article.

15. The method of claim 14 , wherein the machine learning image recognition process comprises at least one of a convolution neural network (“CNN”), a region-based convolution neural network (“R-CNN”), a deep belief network (“DBN”), or a deep neural network (“DNN”) image recognition process.

16. The method of claim 14 , wherein the machine learning image recognition process comprises at least one of image classification, image segmentation, key point detection, or feature extraction.

17. The method of claim 13 , wherein the folding protocol comprises a sequence of pivoting actions of the one or more folding panels as actuated by the actuating assembly.

18. The method of claim 17 , wherein the folding protocol for pants comprises:
actuating a left panel of the one or more folding panels; and
actuating a right panel of the one or more folding panels.

19. The method of claim 17 , wherein the folding protocol for shirts comprises:
actuating a left panel of the one or more folding panels;
actuating a right panel of the one or more folding panels; and
actuating a bottom panel of the one or more folding panels.

20. The laundry folding appliance of claim 1 , wherein a first panel of the one or more folding panels is rotatable about a first axis, a second panel of the one or more folding panels is rotatable about a second axis, and the first axis and the second axis are not parallel.
