1 is a flow chart of a control method of a washing machine according to a preferred embodiment of the present invention.

detailed description

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Preferred embodiment 1:

The preferred embodiment discloses a washing machine control method. As shown in FIG. 1 , the control method includes the following steps:

Step 1. Take a picture or video of each laundry to be washed. It can be photographed or photographed before each laundry to be washed into the washing tub, or photographed or photographed during the rolling and weighing of the laundry to be washed, depending on the specific use.

In view of the fact that the photograph taken after the laundry is smashed into a group or the image obtained by the camera is difficult to reflect the overall appearance of the laundry, it is preferred to deploy the laundry to be photographed in front of the camera before being put into the washing tub, and the resulting picture or picture is most Clear and accurate.

Use 3D imaging technology to take photos or videos of each laundry to ensure that the information obtained by the photos or images is more abundant, and strive to characterize each laundry to be washed with as few pictures or photos as possible.

When using the camera mode, the laundry to be washed is usually in a state of motion. In this case, multiple pictures are taken from the video, and multiple pictures are combined to confirm the basic information of the clothes.

Step 2: The control device obtains at least one photo or at least one image taken from the video screen. The photo or image must be clear enough that it cannot be used for comparison. When the photo or picture has a repetition, keep the clearest one and delete the rest.

Step 3. The control device compares the obtained photo or picture with the clothing data in the database to confirm the basic information of each laundry to be washed. The basic information of clothing mainly includes but is not limited to color, pattern, texture, material (including cotton, linen, chemical fiber, polyester, silk, silk, down, denim, etc.), whether it is faded, category (including underwear, jacket, pants, children) Clothing, bed sheets, quilts, etc., weight, style type, optimal washing temperature, washing requirements and/or brand, as the basis for subsequent determination of the washing procedure.

The database can be set in the local server; it can also be set in a remote server or a cloud server, and through the Internet of Things communication, data reports can be formed.

After confirming the basic information of the laundry to be washed, the control device can record the number of times of cleaning each piece of clothing or designated clothes. When the cleaning times of some clothes reach the set value, the control device can remind the user that “xx clothes have been worn x times, please carry out maintenance treatment”; the control device can also grasp the user's preferences according to the number of times of washing (color, material, Brands and other aspects of preferences, more targeted when recommending new trends for users.

Step 4. The control device automatically selects a washing program based on the basic information of all the laundry to be washed. Washing procedures include, but are not limited to, whether it is possible to mix, wash time, water temperature at the time of washing, type of detergent, number of washes, and/or number of rinses.

The washing machine to which the above control method is applied includes a photographing device or an image pickup device which is mounted on the upper cover of the washing machine. When the washing is prepared, the laundry to be washed will be put into the inner cylinder through the opening, and the upturned upper cover is just aligned with the opening of the inner cylinder, and the photographing device or the camera device can be more conveniently disposed on the upper cover. Take pictures or take pictures of laundry.

Preferred embodiment two:

The preferred embodiment discloses a washing machine control method and a washing machine, the contents of which are substantially the same as those of the preferred embodiment 1. The control method is to photograph or photograph each laundry to be washed before each laundry to be washed into the washing tub or during the tumble weighing of the laundry to be washed, and the control device intercepts the self-recording image according to at least one photo or at least one piece. The picture is compared with the clothing data in the database to confirm the basic information of each piece of laundry to be washed; the control device automatically selects the washing program according to the basic information of all the clothes to be washed.

The difference is that the specific steps of the control method are not limited, and the basic information of the clothing can be judged according to the picture of the laundry to be washed or the picture captured by the video screen; the specific method of photographing or photographing, and the equipment used are not limited, A clear image of the garment is obtained; the basic information of the garment includes not only the color, the pattern, the texture, the material and/or the brand, but also other information that can be used as a basis for determining the washing procedure.

The washing machine applying the above control method may include a photographing device and an image capturing device at the same time. The specific mounting positions of the photographing device and the camera device are not limited, and may be installed on the upper cover of the washing machine, or may be installed in the inner tube of the washing machine or the observation window. The camera device and the camera device can also be separately arranged, and the laundry can be conveniently or accurately taken for photographing or imaging.
