Detailed Description

Fig. 1 is an external view of embodiments of an automatic washing machine 10 according to the present invention, fig. 2 is an internal structure view of embodiments of the automatic washing machine 10 according to the present invention, and fig. 3 is a control schematic block diagram of embodiments of the automatic washing machine 10 according to the present invention, the automatic washing machine 10 of the present embodiment may generally include an outer tub 110, an inner tub 120, a hyperspectral imaging apparatus 200, an image analysis apparatus 300, and a washing execution system 400, the automatic washing machine 10 of the present embodiment is described by taking a front loading type drum washing machine as an example, and since the washing machine of other configurations generally has differences only in the structures of the inner tub 120, the outer tub 110, the supporting manner, and the like, but the operation principle and other structures are substantially , and it is possible for a person skilled in the art to apply the solution of the present embodiment to washing machines of other configurations based on understanding the solution of the application of the present embodiment to the front loading type drum washing machine.

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 automatic washing of this embodiment utilizes this hyperspectral imaging device 200 to place the district to shoot to the clothing of interior bucket 120, and image analysis device 300 obtains the washing scheme according to the hyperspectral image analysis who shoots and obtains, accurately confirms the material of the clothing of being washed, and the washing scheme that determines suits with the clothing of being washed, and the pertinence of washing scheme is stronger, has improved washing efficiency, and under the prerequisite of guaranteeing to wash cleanly, the damage that the washing wearing and tearing of reduction clothing caused effectively.

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.

Fig. 4 is a schematic diagram of the combination of the mid-high spectrum imaging device 200 and the wide spectrum light source 220 of the automatic washing machine 10 according to embodiments of the present invention, the wide spectrum light source 220 may include integrated LEDs, and the light emission spectrum range of the integrated LEDs is set to be 400 to 2400nm, in this embodiment, or more integrated LEDs (4 are shown in the figure, but a specific number may be set according to the light requirement in practical application) may be provided, for example, the integrated LEDs may be disposed around the mid-high spectrum 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 image analysis device 300 is in data connection with the hyperspectral imaging device 200 and is configured to configure a washing protocol according to the hyperspectral image. The washing pattern may include the type of detergent put in by the detergent putting device 410, a putting amount, a putting time, a water discharge amount, a water discharge time, and a rotation speed of the driving motor 430 at each stage of the washing process, that is, the washing pattern may specify washing parameters such as a washing time, a washing intensity, a detergent addition amount, a detergent type, and a rinsing frequency.

The analysis process of the image analysis apparatus 300 may be: extracting image characteristic information and characteristic spectrum information from hyperspectral data shot by the hyperspectral imaging device 200; identifying the material characteristics of the clothes according to the image characteristic information and the characteristic spectrum information to determine the material of the clothes to be washed; and determining a corresponding washing scheme according to the material of the clothes to be washed. The absorption peak positions and the intensities of different molecular groups in the clothes material are different, and the material identification is carried out by analyzing the molecular vibration reflected light information and combining a chemometrics algorithm, so that the clothes material information and the content information of different materials can be obtained.

For example, the characteristic spectrum information of the hyperspectral data may include a characteristic peak of the spectral data, and a preset material identification model may be used to identify the characteristic peak of the spectral data 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 clothing materials and the characteristic peak of the corresponding spectral data by training (a training sample may be formed by combining various materials such as wool, cotton, blended fabrics, silk, polyester, chinlon, hemp fabrics, and the like, and the spectral data thereof with a chemometric algorithm). 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 materials of the clothes may be multiple, the image analysis device 300 may further determine the material type and the number of the clothes to be washed by using a neural network algorithm to discriminate the image characteristics in the hyperspectral data of the clothes to be washed; thereby respectively extracting the characteristic information of the hyperspectral images of the clothes to be washed made of various materials.

In the case that the laundry contains a plurality of materials, the image analysis apparatus 300 may determine the washing solutions corresponding to the plurality of materials, and select an alternative washing solution from the washing solutions corresponding to the plurality of 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.

In order to solve the problem that a plurality of pieces of clothes are put in simultaneously, so that part of the clothes are blocked, the inner barrel 120 is driven to rotate by a preset angle after the clothes are put in, the hyperspectral imaging device 200 shoots hyperspectral images for a plurality of times to obtain a plurality of groups of hyperspectral images, and the clothes material identification is respectively carried out, so that all clothes material identification results are obtained.

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, when the image analysis device 300 determines that the material of the clothes to be washed is not suitable for simultaneous cleaning or the alternative washing scheme cannot be determined, prompt information can be output to prompt the user to intervene.

The washing machine 10 of the present embodiment may further be provided with a display screen 500, and the display screen 500 may be configured to output an interface corresponding to a washing scheme, for example, output the above prompt information, which may include information about the material of the clothes that cannot be washed at the same time, an operation prompt for reminding a 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 image analysis apparatus 300 to determine the washing pattern and automatically complete the washing process.

The washing machine 10 of the embodiment can accurately determine the material of the washed clothes by means of the hyperspectral image analysis technology, the determined washing scheme is adaptive to the washed clothes, the pertinence of the washing scheme is stronger, the washing efficiency is improved, and the damage caused by washing abrasion of the clothes is effectively reduced on the premise of ensuring the washing cleanness.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
