An outer tub 110 of the washing machine 10 for holding washing water; the inner tub 120 is rotatably provided in the outer tub 110 for accommodating laundry to be washed. The front of the inner tub 120 may have an opening for laundry to be put in. The inner tub 120 has a plurality of lifting ribs therein, and is driven by the motor 430 and the transmission mechanism to rotate regularly, so that the laundry is rolled and kneaded in the inner tub 120, thereby achieving the purpose of washing. The washing machine 10 can be controlled to perform washing operations such as water feeding, detergent feeding, washing, warming, rinsing, draining, and dewatering. Since the specific washing structure is well known to those skilled in the art, it will not be described herein.
The materials of the laundry are more and more abundant, and the laundry of each material has different washing requirements (for example, different requirements on washing time, washing strength, detergent addition amount, rinsing times and dewatering strength) due to the characteristics of the material. The conventional washing control manner selected by the user from the preset washing modes has failed to satisfy the user's demand. The washing machine 10 of the embodiment utilizes the hyperspectral imaging device 200 to shoot the clothes placement area of the inner barrel 120, the controller 300 can analyze and obtain a washing scheme according to the hyperspectral image obtained by shooting and control the washing execution system 400 to execute, thereby accurately determining the material of the washed clothes, determining the washing scheme to be adapted to the washed clothes, having stronger pertinence of the washing scheme, improving the washing efficiency, and effectively reducing the damage caused by the washing abrasion of the clothes on the premise of ensuring the washing cleanness.
The hyperspectral imaging apparatus 200 may be disposed at an upper portion of the opening (i.e., an upper portion of the inner side of the body 130) with a photographing direction configured to face the laundry placement area of the inner tub 120 (i.e., a middle-lower area of the inner tub 120) and configured to photograph a hyperspectral image of the laundry to be washed.
alternative arrangement structure is that the hyperspectral imaging device 200 is installed at the outer barrel 110 near the body 130, and the hyperspectral imaging device 200 is also provided with a transparent cover 210 at the installation position to isolate the hyperspectral imaging device 200 from the inner barrel 120.
The side of the transparent cover 210 facing the inner barrel 120 is coated with a super-hydrophobic nano coating to avoid water stains affecting the shooting effect of the hyperspectral imaging device 200, the super-hydrophobic nano coating can be prepared mainly based on acrylic polyurethane, is good in wear resistance and excellent in mechanical property, has good tolerance to strong acid and strong alkaline media, and in the experimental stage, the contact angle of the super-hydrophobic nano coating is still larger than 150 degrees after the super-hydrophobic nano coating is polished for 300 times by abrasive paper, so that the hydrophobic effect is good.
By using the super-hydrophobic nano coating, the transparent cover 210 does not form water stain accumulation, and the requirement of the hyperspectral imaging device 200 for shooting in the washing machine 10 is met.
Since the light inside the washing machine 10 cannot satisfy the photographing requirement, the washing machine 10 further includes: and a broad spectrum light source 220, also disposed at the upper portion of the opening, for providing photographing light to the hyperspectral imaging apparatus 200.
The broad spectrum light source 220 may comprise integrated LEDs, the light emission spectrum range of which is set to be up to 400 to 2400nm in this embodiment or more integrated LEDs may be provided, for example, the integrated LEDs may be provided around the hyperspectral imaging device 200 and shielded by the transparent cover 210.
In other embodiments, the broad spectrum light source 220 may be separately disposed from the hyperspectral imager 200, for example, on both sides of the upper portion of the body 130 of the washing machine 10 .
The hyperspectral image shot by the hyperspectral imaging device 200 can include image data and spectral data, for example, each pixel point can include an image pixel element and a spectral wavelength element of the pixel, that is, each pixel point is multivariate data sets and includes a plurality of image pixel element data and sets of spectral wavelength elements, so the hyperspectral data simultaneously obtains continuous spectral data of each pixel point and continuous image data of each spectral band.
The controller 300 includes a memory 310 and a processor 320, wherein the memory 310 stores a computer program, and the computer program can process the hyperspectral image, automatically determine a washing scheme, and control the washing execution system 400 to complete the washing scheme when being executed by the processor 320, thereby implementing an automatic washing function of the washing machine 10. The laundry control method of the washing machine 10 of the present embodiment will be described below.
Fig. 4 is a schematic diagram of a laundry control method of a washing machine according to embodiments of the present invention, which is performed by the processor 320 of the controller 300 of the washing machine 10 in the above-described embodiments to perform control of laundry washing.
Step S402, controlling the hyperspectral imaging device 200 to shoot and acquiring a hyperspectral image of the clothes to be washed shot by the hyperspectral imaging device 200, wherein the shooting control process can include acquiring a signal of turning off the washing machine 10, detecting whether the clothes to be washed are put in or not after the washing machine 10 is confirmed to be turned off, and controlling the hyperspectral imaging device 200 to shoot the hyperspectral image under the condition that the clothes to be washed are confirmed to be put in.
The process of acquiring the off signal of the washing machine 10 may include controlling the hyperspectral imaging device 200 to photograph the clothes placement area to obtain image data of the clothes placement area, determining whether clothes exist in the clothes placement area according to the image data, if the clothes exist, comparing the image data with washing history data to determine whether the clothes in the clothes placement area are the clothes washed before opening , and if the clothes washed before opening are not the clothes washed, determining to put the clothes to be washed.
When the hyperspectral imaging device 200 is controlled to shoot, the hyperspectral light source corresponding to the hyperspectral imaging device can be started at the same time to provide the required hyperspectral light for shooting.
S404, extracting characteristic information of the hyperspectral image, and identifying the material of the clothes to be washed according to the characteristic information; the extracting of the characteristic information of the hyperspectral image may include a characteristic peak of spectral data in the hyperspectral image, and the process of identifying the material of the laundry by using the characteristic peak of the spectral data may include: and identifying the characteristic peak of the spectral data by using a preset material identification model to obtain a material type corresponding to the characteristic peak of the spectral data, wherein the material identification model is obtained in advance according to various clothes materials and the characteristic peak of the corresponding spectral data through training. When the material identification model is trained, various materials such as wool, cotton fabrics, blended fabrics, silk, terylene, chinlon, hemp fabrics and the like and spectral data thereof can be combined with a chemometrics algorithm to form a training sample. For example: the spectral characteristic peak of the pure cotton material is 1950 nm; the spectral characteristic peak of the chemical fiber fabric is 1400 nm.
Since the number of the clothes to be washed may be multiple and the material thereof may be multiple, the step of extracting the characteristic information of the hyperspectral image may further include: carrying out image recognition on the image data by utilizing a neural network algorithm to determine different extraction areas of the image data; and respectively extracting characteristic peaks of the spectral data of each region from the extraction regions so as to respectively determine the clothes material of each region. For example, the image data is subjected to image recognition by using a neural network algorithm, so that regions (including regions with different colors and regions with different light intensities) presenting different image characteristics in the clothes placement region can be recognized, the regions presenting different image characteristics are respectively used as extraction regions, characteristic peaks of the spectral data are respectively extracted, and the clothes material is respectively determined according to the characteristic peaks of the spectral data of the regions.
Step S406, configuring a washing pattern according to the material of the laundry, and controlling the washing execution system 400 of the washing machine 10 to execute the washing pattern. Under the condition that the clothes to be washed contain multiple materials, the alternative scheme can be selected according to the corresponding washing scheme of the multiple materials, and the alternative scheme meets the condition of avoiding the damage of the multiple materials. The alternative washing scheme is selected as the scheme with the least damage to various clothes to be washed or the scheme with the shortest washing time.
Because some clothes made of materials cannot be shuffled, for example, the cleaning requirements of real silk materials and some chemical fiber materials are different, and meanwhile, the cleaning of all the clothes cannot be met, and the clothes can be damaged. Therefore, prompt information can be output under the condition that the materials of the clothes to be washed are not suitable for being washed at the same time or alternative washing schemes cannot be determined, so that a user can be prompted to intervene.
And in the case that no alternative scheme exists in the corresponding washing schemes made of various materials, outputting prompt information for prompting that the clothes to be washed cannot be shuffled. In the case that the washing machine 10 of the present embodiment is provided with the display screen 500, an interface corresponding to a washing scheme may be output by using the display screen 500, for example, the prompt information may include information of the material of the clothes that cannot be washed at the same time, an operation prompt for prompting the user to take out the clothes, and the like.
The washing performing system 400 may include a detergent dispenser 410 for dispensing detergent into the outer tub 110 during a washing process, a water inlet 420 for discharging water into the outer tub 110 during the washing process, a driving motor 430 for driving the inner tub 120 to rotate, a drain 440, and the like. The washing execution system 400 may execute the controller 300 to determine the washing course and automatically complete the washing course.
In the washing process, the hyperspectral imaging device 200 can also be used for shooting the washing mixed liquid or the rinsing waste liquid after rinsing is completed to obtain hyperspectral images of the washing mixed liquid and the rinsing waste liquid, so that the hyperspectral images of the washing mixed liquid and the rinsing waste liquid are used for determining the concentration of the detergent in the washing mixed liquid and the rinsing waste liquid, and the washing process is adjusted.
For example, after determining the washing program, the detergent dispenser 410 may be controlled to dispense the detergent according to the initial dispensing amount; starting the hyperspectral imaging device 200 to shoot the washing mixed liquid, and determining the concentration of the detergent in the washing mixed liquid according to the hyperspectral image characteristic information of the washing mixed liquid; and controlling the detergent feeding device to increase the feeding amount of the detergent under the condition that the concentration of the detergent in the washing mixed liquid is lower than the washing target concentration.
The step of determining the detergent concentration of the washing mixed liquor according to the hyperspectral image characteristic information of the washing mixed liquor comprises the following steps: selecting a plurality of pixel points in different areas of a hyperspectral image of the washing mixed liquid, and respectively acquiring spectral data of the pixel points; extracting a spectrum curve of the spectrum data of the plurality of pixel points; respectively identifying the spectral curves of the spectral data of the multiple pixel points by using a preset detergent concentration detection model to obtain the corresponding detergent concentrations of the multiple pixel points, wherein the detergent concentration detection model is obtained by training the spectral curves of washing mixed liquor with different detergent concentrations in advance; and comprehensively judging the detergent concentrations corresponding to the multiple pixel points by using a chemometrics algorithm to obtain the detergent concentration of the washing mixed liquid.
After the washing machine finishes rinsing, the hyperspectral imaging device 200 can also shoot the rinsing waste liquid and acquire a hyperspectral image of the rinsing waste liquid shot by the hyperspectral imaging device 200. Therefore, the concentration of the detergent in the rinsing waste liquid can be determined according to the hyperspectral image characteristic information of the rinsing waste liquid; and controlling the washing machine to perform rinsing again under the condition that the concentration of the detergent in the rinsing waste liquid is higher than the rinsing target concentration. The analysis process of the hyperspectral image of the rinsing waste liquid is basically the same as the determination of the concentration of the detergent of the washing mixed liquid, and the details are not repeated.
The washing condition can be more in line with the requirement of clothes material through the content (concentration) of the detergent, and whether the washing is clean can be determined through the concentration of the detergent of the washing waste liquid, so that the washing effect is further improved .

The data can be used for identifying the material quality. After identification, a washing protocol consistent with the material is determined. The washing course sets washing time, washing intensity, detergent addition amount and rinsing times.
After the washing scheme is determined, water is automatically drained and detergent is added, the condition that the washing requirement is met probably due to the fact that the amount of the added detergent is used, then the concentration of the detergent can be detected by means of a hyperspectral imaging device, and if the concentration of the detergent is not enough, the detergent amount is added again until the washing requirement is met.
And before the washing is finished, detecting the detergent concentration of the rinsing waste liquid by using the hyperspectral imaging device again, finishing the washing process if the detergent concentration is small enough, and continuing rinsing until the detergent concentration is small enough to finish the washing if the detergent concentration is too large.
