In step 1, a photograph or video of each piece of clothes to be washed is taken. Depending on specific use conditions, the photograph or video of each piece of clothes to be washed may be taken before the clothes are thrown into a washing drum, or during a process of rolling and weighing the clothes.
Considering that the photograph or picture captured after the clothes to be washed are kneaded is difficult to reflect an entire shape and appearance of the clothes, the clothes to be washed are preferably unfolded and photographed in front of a camera before thrown into the washing drum. Accordingly, the photograph or picture captured at this time is most clear and accurate.
The photograph or video of each piece of clothes to be washed taken by adopting a three-dimensional imaging technology, so as to ensure that the captured picture or image is informative. Thus, it is tried to use as few pictures or images as possible to represent each piece of clothes to be washed.
In the case that the video of the clothes to be washed is taken, the clothes are generally in a motion state. In this case, a plurality of pictures need to be extracted from the video, and the basic information of the clothes is confirmed in combination with the plurality of pictures.
In step 2, at least one photograph or at least one picture extracted from the video is obtained by a control apparatus. The photograph or picture should be clear enough. Otherwise, the photograph or picture cannot be used for comparison. When the photographs or pictures are repeated, the clearest one is reserved and the others are deleted.
In Step 3, the photograph or picture is compared with clothes data in the database by the control apparatus to confirm the basic information of each piece of clothes to be washed. The basic information of the clothes mainly includes but not limited to colors, patterns, texture, material (including cotton, linen, chemical fiber, dacron, silk, silk fabric, down feather, denim and the like), decoloration property, types (including underwear, overcoat, trousers, children clothes, sheet, quilt covers and the like), weight, styles, best washing temperature, washing requirements and/or brands, which are uses as a basis for determining the washing procedure subsequently.
The database may be arranged in a local server. Optionally, the database may also be provided in a remote server or cloud server, and may be communicated through Internet of things to form data reports and the like.
After the basic information of the clothes to be washed is confirmed, washing times of each piece of clothes or specified clothes is recorded by the control apparatus. The control apparatus is configured to remind the user that “xx clothes have been worn x times, and need to be maintained and treated” when the washing times of some clothes reach a set value. The control apparatus is further configured to master user preferences (preferences in aspects of colors, material, brands and the like) according to the washing times of the clothes, so as to recommend new fashionable products for the user pertinently.
In Step 4, the washing procedure is automatically selected by the control apparatus according to the basic information of all the clothes to be washed. The washing procedure includes but not limited to mixed washing or not, washing time, water temperature during washing, detergent types, washing times and/or rinsing times.
A washing machine applying the above control method includes a photographing apparatus and/or a videoing apparatus. The photographing apparatus and/or the videoing apparatus is installed on an upper cover of the washing machine. At the time of preparing washing, the clothes to be washed are thrown into an inner drum through an opening. The turned-up upper cover is exactly aligned with the opening of the inner drum.
