Example 1

As shown in fig. 1, the present embodiment provides a control method of a washing machine.

The method is to detect the water draining of the washing machine and judge whether the clothes are washed cleanly. The solution provided in this embodiment is to detect the drain of the washing machine after the last rinsing.

The embodiment further comprises judging that the clothes are not washed cleanly if the drainage of the washing machine contains detergent components and/or stain components.

The scheme provided by the embodiment is that the intelligent terminal is in communication connection with the washing machine, a washing application program is installed on the intelligent terminal, and an NFC chip is also installed on the washing machine. In the using process, a user can rapidly open a washing application program on the intelligent terminal through NFC, and washing parameters are set according to the information of clothes. In addition, in the embodiment, the washing parameters corresponding to different pieces of clothes information are obtained through a large number of experimental calculations in a laboratory, so that the washing parameters matched with the clothes information can be set only according to the clothes information, and a good washing effect is achieved. The clothes information comprises information such as images, types, brands, materials, money numbers, colors, sizes, prices and the like of clothes. The washing machine performs a washing operation according to the set washing parameters. And when the washing machine executes the rinsing program for the last time, detecting the drainage of the washing machine after the execution is finished, and judging that the clothes are not washed completely if the drainage of the washing machine contains detergent components or stain components.

In a further aspect of this embodiment, if the detergent component and/or the stain component contained in the drain water of the washing machine reaches the set content threshold, it is determined that the laundry is not washed clean.

Since it is considered that, in actual circumstances, even if the laundry is washed clean, there is a residue of detergent components or stain components in the drain water of the washing machine after the end of rinsing. Therefore, as a further aspect of the present embodiment, the detergent component content and the stain component content detected in the discharged sewage are further defined, and if the detergent component content or the stain component content detected in the discharged sewage is greater than the set content threshold, it is verified that the laundry is not washed clean; and if the content of the detergent component or the content of the stain component detected in the discharged sewage is smaller than or equal to a set content threshold value, the clothes are proved to be washed cleanly. The set content threshold value can be set by a user according to actual conditions. In this embodiment, the content of the detergent may be the content of the detergent by detecting the content of the surfactant in the washing water, and the content of the detergent is reflected by the content of the surfactant, and the detecting device is a signal generating device, a surface acoustic wave sensor and a signal detecting circuit which are installed at the drain pipe position of the washing machine. The stain components described in this embodiment are mainly sweat components, and the sweat components and the content are detected by installing a sweat component detecting device at the position of the drain pipe of the washing machine, which is the prior art, through which the components and the content of sweat in the drain water of the washing machine can be detected.

The technical scheme of the embodiment further comprises the steps of judging that clothes are not washed cleanly and adjusting washing parameters.

The washing parameters are adjusted in the current washing process or are adjusted when the clothes matched with the clothes in the current washing are washed next time.

In the solution of this embodiment, according to the collected laundry information, it is determined that the washing parameter is adjusted in the current washing process or is adjusted when the next laundry matching the current laundry is washed.

Adjusting the washing parameters includes increasing the number of rinsing times and/or increasing the temperature of the washing water and/or extending the washing time.

If the clothes are not washed completely, judging whether the content of the detergent is larger than a set threshold value or the content of the stain component is larger than the set threshold value. If the laundry is not washed clean because the detergent content in the drain water of the washing machine is greater than a preset threshold, the washing parameters may be adjusted, the adjusted washing parameters being to increase the number of rinsing times. If the laundry is not washed clean because the content of the soil components in the drain water of the washing machine is greater than a preset threshold, the washing parameters may be adjusted, which are to raise the temperature of the washing water or to extend the washing time. After determining what material content in the water discharged from the washing machine exceeds a set threshold, judging whether to adjust the washing parameters in the current washing process according to the information of clothes. If the material of the clothes has no requirement on the washing times, the washing parameters are adjusted in the washing program, and the washing machine executes the washing operation again according to the adjusted washing parameters, so that the clothes are washed more cleanly. For example, if the content of the stain component is detected to be greater than the set threshold value in the water discharge of the washing machine, the washed clothes are determined to be the polyester outer cover according to the collected clothes information, the materials of the clothes are wear-resistant, the washing parameters can be adjusted to prolong the washing time or increase the washing strength or increase the temperature of the washing water, and the washing machine executes the washing procedure again to wash the clothes according to the adjusted washing parameters. If the content of the detergent detected in the water discharged from the washing machine is larger than the set threshold, the information of the clothes is cotton T-shirt, at the moment, the washing parameters can be adjusted to increase the number of times of rinsing, at the moment, the washing machine executes the adjusted washing parameters, and the washing clothes are subjected to a rinsing program again, so that the clothes can be washed cleanly in the current washing process.

In another aspect of this embodiment, it is determined that the laundry is not washed cleanly, and the washing parameters are adjusted when the next laundry is washed and the current laundry is matched according to the laundry information.

In this scheme provided in this embodiment, it is first determined whether the laundry is due to the residual amount of the detergent exceeding a set threshold or the content of the soil component exceeding a set threshold, and then it is determined whether the adjusted washing parameter is performed at the present time or at the next time of washing according to the information of the laundry. The scheme is mainly aimed at the fact that the information such as the material quality of clothes is not suitable for executing the washing program again, and if the washing program is continuously executed at this time, the clothes can be damaged. Therefore, in the solution of this embodiment, if the laundry is not washed completely, but cannot be washed again, the washing parameters are adjusted according to the condition of the stain component, the adjusted washing parameters and the laundry information are recorded, and the adjusted washing parameters are directly called to make the washing machine execute the washing procedure when the laundry matching with the laundry is next washed. Of course, the washing parameter may be readjusted at the next time of re-washing the laundry matched with the laundry. In this embodiment, the laundry matching the next washing with the current washing is the same laundry as the next washing and the current washing, and is the same laundry; or the information of the next washed clothes is similar to the information of the current washed clothes, and the similarity degree means that the materials of the clothes are the same and the types of the clothes are the same. For example, if the laundry is a cotton T-shirt and the laundry is a cotton coat, the laundry information is not matched at this time, and the required washing strength is different because the weight of the T-shirt and the coat are different, so the laundry information is not matched. Of course, the degree of similarity of the laundry may be set according to the actual needs of the user.

In the embodiment, the drain water of the washing machine after the last rinsing is detected to detect whether the drain water of the washing machine contains detergent or stain components, so that whether clothes are washed cleanly or not is judged, and the method is simple to operate. In order to make the detection result more accurate, the scheme of the embodiment is further improved, the content of the detergent or the content of the stain in the discharged sewage is detected, and compared with a set content threshold value, if the content of the detergent or the content of the stain is larger than the set content threshold value, the condition that the clothes are not washed cleanly is proved; and if the detergent content or the stain content is less than or equal to the set content threshold value, the clothes are proved to be washed cleanly. According to the detection result, judging whether the washing parameters are adjusted in the current washing process or in the next washing process according to the information of the clothes, so that the clothes can be washed cleanly. The scheme provided by the invention is simple to operate and accurate in measurement result.

Example two

This embodiment is further described on the basis of the above embodiment

As shown in fig. 2, the scheme of the embodiment includes that a picture of the washed clothes is obtained, and the picture is compared with a picture of the clothes before washing to determine the wrinkling condition of the clothes.

And if the ratio of the fold area of the clothes subjected to washing to the whole area of the clothes is larger than the preset ratio threshold value, adjusting the washing program.

And adjusting the washing parameters when washing the clothes matched with the clothes again.

After the clothes are washed, the picture of the washed clothes is obtained, the picture is compared with the clothes image before washing, the fold area of the clothes is determined, the fold area of the washed clothes is calculated, and the proportion of the fold area to the whole area of the clothes is calculated, so that whether the washing parameters need to be adjusted in the next washing process is judged, and the number of folds of the washed clothes is reduced. Wherein the number of wrinkles of the laundry may be reduced by decreasing the dehydration rotation speed or increasing the shaking-out time. In this embodiment, the criterion for wrinkles is that the image of the washed laundry is compared with the image of the laundry before washing, and if the linear structure not present appears on the basis of the image of the laundry before washing, it is determined that wrinkles appear. And calculating the sum of areas where wrinkles appear and the ratio of the sum of areas of the wrinkles to the whole area of the clothes, if the calculated result is larger than a preset ratio threshold value, proving that the wrinkles are more, and adjusting washing parameters when the clothes matched with the clothes are washed again. The preset threshold value can be set by a user according to actual conditions and needs.

In this embodiment, the image of the laundry is collected as the image of the laundry before washing, before the laundry is washed. The method for collecting the images of the clothes before washing is that the whole images of the clothes are collected by the image collecting equipment, and the whole images comprise the front surface and the back surface of the clothes. The preferable scheme of the embodiment is that an image of the laundry is collected before washing, the image of the laundry stored in the intelligent wardrobe is matched with the image of the laundry according to the collected image of the laundry, and the image of the laundry in the intelligent wardrobe is used as the image of the laundry before washing. In general, a user can iron and put clean clothes into a wardrobe, so that a picture of the clothes to be washed stored in the intelligent wardrobe is used as a picture of the clothes before washing, and the intelligent wardrobe is only required to be in communication connection with a washing machine. The user can also directly designate the clothes picture stored in the intelligent wardrobe as a clothes image before washing, and the information such as the image of the clothes to be washed in the intelligent wardrobe is determined after the information of the clothes to be washed is acquired and matched with the information in the intelligent wardrobe.

Because not only the clothes but also the information of the clothes are stored in the intelligent wardrobe, the clothes information comprises the information of images, types, brands, materials, money numbers, colors, sizes, prices and the like of the clothes. The clothes information recorded in the intelligent wardrobe can be directly sent to the washing machine, and the intelligent terminal can directly determine the washing parameters of the clothes by acquiring the information.

After the laundry is washed, a laundry image is acquired. The image of the washed clothes is an integral image of the clothes acquired by the image acquisition equipment after the clothes are washed, and the integral image comprises the front surface and the back surface of the clothes. In this embodiment, the image of the laundry after washing is an image of the laundry collected by the image collecting device on the intelligent clothes hanger, and the intelligent clothes hanger is connected with the washing machine in a communication manner and is also connected with the intelligent terminal in a communication manner, and the intelligent terminal is provided with a program for analyzing the image. Because the intelligent clothes hanger can judge the condition of clothes on the clothes hanger through the collected images and execute corresponding operations, such as rising to a clothes placing position or a storage position, the clothes images collected by the intelligent clothes hanger can be used as clothes images for finishing washing, and the scheme does not need to additionally collect the clothes images for finishing washing, so that the program is saved, and the time is saved.

In another aspect of this embodiment, the image of the washed laundry may be acquired at other stages after the washing is completed, for example, after the spin-drying is completed or after the drying is completed. In the washing procedure, whether the clothes dryer needs to be preheated is confirmed to a user, after the user confirms, the clothes dryer is started and preheated, after washing is finished, the user is reminded of drying operation on washed clothes through an intelligent terminal or a voice sound box, after the drying is finished, the wrinkling condition of the clothes is detected, the wrinkling information is reported to the user, washing parameters adjusted according to the wrinkling information are stored as independent labels, and the stored labels can be directly called when the clothes are rewashed next time. The mode of collection can also be to collect the image of the clothes which is washed by the collection device, such as a camera or a mobile phone. Wherein the camera is communicatively coupled to either the camera or a control system that collects and analyzes the images.

Whether the proportion of the fold area of the washed clothes to the whole area of the clothes is larger than a preset proportion threshold value is calculated through comparison of the pictures, if the proportion of the fold area of the washed clothes to the whole area of the clothes is larger than the preset proportion threshold value, the fact that the folds are too many is indicated, the washing parameters are adjusted when the clothes matched with the clothes at this time are washed again, and the rotating speed during dehydration can be reduced or the shaking time can be increased. As for the criteria for matching the clothing information, the above embodiment has been described, and the user may set different criteria for matching the clothing.

According to the scheme provided by the embodiment, the image of the washed clothes is obtained and is compared with the image of the clothes before washing to judge the wrinkling situation of the clothes, if the proportion of the wrinkling area of the washed clothes to the whole area of the clothes is larger than the preset threshold value, the wrinkling is reduced by adjusting the washing parameters when the clothes matched with the clothes are washed again, and therefore a good washing effect of the clothes can be achieved.

Example III

This embodiment is a further description of the above embodiments

And if the clothes are not washed cleanly, adjusting the washing parameters.

The method for judging stains on the washed clothes in the embodiment is that firstly, the positions of the clothes images before washing and the positions of the clothes images after washing are extracted from the clothes images after washing, then whether colors, patterns or pattern layers of peripheral clothes at the positions of the clothes images after washing are consistent or not is analyzed, if so, the clothes are proved to be washed completely, and if not, the clothes are proved to be not washed completely. That is, the positions of the clothes image before washing and the positions of the stains, which are positions where the clothes image after washing changes, are identical to each other in color and image around the positions where the stains are changed if the clothes image is washed completely, and two layers cannot appear. If the stain is not completely washed but after washing, the stain is shallowed, the two images are compared, or the change is made, the changed position is compared with the surrounding color and layer, the color is inconsistent, and the additional layer exists, the condition that the clothes are not washed is confirmed.

The adjustment of the washing parameters means extending the washing time and/or increasing the number of rinsing times.

Recording the washed clothes and the adjusted washing parameters after washing is finished; and when the clothes are washed again, identifying the clothes to be washed, and if the clothes to be washed are matched with the recorded clothes to be washed, running a washing program according to the adjusted washing parameters.

If the laundry information of the laundry is the same as the recorded laundry information of the laundry, judging that the laundry information of the laundry is matched with the recorded laundry information.

In this embodiment, after the washing is finished, a washed clothes image is collected, and the washed clothes image is compared with a collected clothes image before washing, if the comparison is performed, it is confirmed that the clothes are not washed completely, the washing parameters of the washing program are adjusted, and the washed clothes information and the adjusted washing parameters are recorded. When the clothes are washed next time, information of the washed clothes is extracted, if the information of the clothes in the next time is the same as the information of the clothes in the last time, the information of the clothes refers to information such as color, style and material of the clothes, that is, the information of the clothes is the same, namely, the same clothes is washed twice. Therefore, after the next piece of clothes information is extracted, when the next piece of clothes is judged to be the piece of clothes which are not washed cleanly, the adjusted washing parameters are directly called in the next piece of clothes, wherein the adjustment of the washing parameters means one or more modes of prolonging the washing time, increasing the rinsing times and increasing the temperature of washing water. And washing clothes by calling the adjusted washing parameters, so that the clothes can be washed cleanly.

According to the technical scheme provided by the embodiment, through comparing the image information of the clothes before and after washing, whether the clothes are provided with stains or not can be intuitively and accurately judged, and whether the clothes are washed cleanly or not is judged. Based on this determination, it is determined whether the washing parameter needs to be adjusted. If not, adjusting the washing parameters, recording the clothes information and the washing parameters, and calling the adjusted washing program when the same or similar clothes to the clothes to be washed are washed again, so that the clothes to be washed achieve a good washing effect.
