[0002] Washing machines are one of the essential smart home appliances in modern family life. From the perspective of clothing cleaning effect, washing temperature is a particularly important factor.

However, when the clothes are produced in different countries or regions, the printing standards of the graphic logos on the washing labels are also different, and the information contained in the washing labels of clothes in different countries or regions is also different. For example, the washing labels of clothes in some countries only include text information and graphic logos, and the washing labels of clothes in some countries also include material information, etc. Therefore, affected by the above factors, the washing machine may find it difficult to accurately identify the washing labels of different clothes, resulting in errors in the judgment results and affecting the washing process of the clothes.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application.

The processor has data and / or signal processing functions. The processor may be implemented in software, hardware, or a combination of the two.

[0051] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] Reference Figure 1 , is a control method for a washing device disclosed in the present application, which comprises the following steps:

[0053] S101: Acquire a washing label image of a target garment.

[0054] Specifically, in some implementations of the present application, in step S101, the image of the washing label of the target clothing can be collected by an image acquisition device, or the image of the washing label of the target clothing can be collected by a mobile terminal. For example, an image acquisition device is installed in the drum of a washing device or on the door body, and in the process of putting the clothing into the drum of the washing device, the washing label of the clothing is placed in front of the image acquisition device, so that the image acquisition device can collect the washing label image, and then the clothing is put into the drum of the washing device. When a mobile terminal is used to collect the washing label image, the mobile terminal must be connected to the washing device for communication. When washing clothing, the washing label image of the target clothing is first collected by the camera of the mobile terminal, so that the washing device obtains the washing label image through the mobile terminal, and then the target clothing is put into the drum of the washing device. It can be understood that the mobile terminal in the present application includes but is not limited to electronic devices such as mobile phones and tablets.

[0055] S102: Determine the location information of the target clothing according to the washing label image.

[0056] The location information includes different countries or regions.

[0057] S103: Select a corresponding graphic identification database according to the location information, input the washing label image into the graphic identification database for graphic comparison, and obtain a first washing temperature.

[0058] It should be noted that in the cloud database of the washing equipment, each location corresponds to a set of graphic identification databases, which are stored in the cloud database and can be updated in real time according to the printing standards of the water washing labels of each location to continuously improve the information in the database. In an optional implementation of the present application, the above-mentioned graphic comparison can be implemented using a neural network algorithm. By training the neural network, the graphic features can be automatically learned and the target graphic can be identified. This technology is a well-known image recognition technology and will not be elaborated in detail in this application.

[0059] S104: Determine a final washing temperature according to the first washing temperature.

[0060] Step S104 specifically means that in some implementations, the first washing temperature can be directly used as the final washing temperature. Of course, in other implementations, when there are other reference factors or identification methods, they can be combined with the above-mentioned first washing temperature to further determine the final washing temperature.

[0061] S105: Control the washing equipment to operate at the final washing temperature.

[0062] It should be understood that, in some embodiments, when the washing temperature is determined only based on the image comparison result in step S103, the final washing temperature is the first washing temperature.

[0063] It should be noted that the above-mentioned washing label image includes text information and graphic identification information. Among them, the text information is not limited to language information, but also includes Arabic numerals or special symbols, such as "maximum washing temperature 80°C", and the graphic identification information is the graphic identification symbol on the washing label. The graphic identification symbol can be used to reflect information such as washing temperature, whether it can be ironed, whether it can be dry-cleaned, etc. The graphic identification symbols expressing the same meaning in different countries or regions may be different.

[0064] Specifically, in step S102, "determining the location information of the target clothing according to the washing label image" includes: detecting the language of the text information, and determining the location information of the target clothing according to the language.

[0065] In step S103, "selecting a corresponding graphic identification database according to the location information, inputting the washing label image into the graphic identification database for graphic comparison, and obtaining the first washing temperature" includes: obtaining graphic identification information, inputting the graphic identification information into the graphic identification database for graphic comparison, and obtaining the first washing temperature. That is, the first washing temperature is determined only by the graphic identification of the washing label.

[0066] When washing clothes, the present application first determines the location information of the clothes according to the washing label image, then retrieves the corresponding location graphic identification database according to the location information, and finally compares the graphics to obtain the first washing temperature, and uses the first washing temperature as the reference value of the final washing temperature. In this way, it can overcome the problem of incorrect recognition results of washing equipment due to differences in washing label printing standards in different countries or regions, thereby improving the accuracy of washing label identification, so that the target clothes can be washed at a relatively ideal temperature, which not only improves the cleaning effect, but also effectively reduces the possibility of damage to the clothes.

[0067] Reference Figure 2 In a possible implementation of the present application, in the above step S104, "determining the final washing temperature according to the first washing temperature" includes:

[0068] S1041: Confirm the confidence of the first washing temperature.

[0069] It should be noted that, since the graphic comparison result cannot be 100% correct, the confidence of the first washing temperature is a percentage value output after the graphic comparison result is completed, which can also be understood as credibility. For example, the graphic identification database includes ten graphics, and each graphic has a different meaning. For example, some graphics represent washing temperature, some graphics represent whether it can be ironed, and some graphics represent whether it can be dry-cleaned, etc. Then, after the collected graphic identification information is input into the graphic identification database and compared with each of the above graphics one by one, a similarity corresponding to each graphic will be obtained. There is no doubt that the sum of the values ​​added together by each similarity is 100%, and the similarity of the graphic representing the washing temperature in the graphic identification database that is finally output is the confidence of the first washing temperature. Of course, it should be understood that the above method is only an exemplary description given in this application. In actual applications, the confidence of the first washing temperature can also be calculated according to other methods.

[0070] S1042: Obtain the second washing temperature according to the text information, and confirm the confidence level of the second washing temperature.

[0071] It should be noted that in step S1042, "obtaining the second washing temperature according to the text information" means directly identifying the text information printed on the washing label image after determining the location information according to the language information. Similarly, "the confidence level of confirming the second washing temperature" is also a percentage value of the recognition result, which can be calculated based on the OCR text recognition technology, and this application will not go into details. The content of the temperature information reflected in the text information is generally, for example, "the maximum washing temperature is 60°C" or "the washing temperature is lower than 60°C", etc. Although the expression method is slightly different, the essential meaning expressed is basically the same.

[0072] S1043: Compare the confidence level of the first washing temperature and the confidence level of the second washing temperature, and determine the final washing temperature according to the temperature value corresponding to the one with higher confidence level.

[0073] For example, if the first washing temperature is "the washing temperature is lower than 40°C" and its confidence is 80%, and the second washing temperature is "the washing temperature is lower than 50°C" and its confidence is 90%, then the second washing temperature should be selected, that is, the final washing temperature is determined according to the second washing temperature. It can be understood that when there are no other factors or identification methods as references, the final washing temperature is the second washing temperature.

[0074] The present application compares the confidence of the recognition result of the text information with the confidence of the comparison result of the graphic logo, and determines the final washing temperature based on the recognition result with higher confidence as the reference washing temperature, that is, the two recognition results are corrected with each other, which can improve the reliability of the final washing temperature and further improve the recognition accuracy.

[0075] It should also be noted that, since some clothes only include graphic identification information, and their text information does not include temperature information or other reference information, steps S1041 to S1043 cannot be performed in this case. Therefore, steps S1041 to S1043 are performed only when the text information of the washing label of the target clothes includes temperature information.

[0076] Reference Figure 3 In a possible implementation of the present application, when the acquired text information of the target clothing includes material information (for example, the fabric is polyester), after step S1043, the control method of the washing device further includes:

[0077] S1044: Determine the material information of the target clothing according to the text information.

[0078] S1045: Determine a third washing temperature of the target clothing according to the material information.

[0079] Regarding step S1045, it should be understood that different materials of clothing generally have their own maximum washing temperatures, for example, the maximum washing temperature of polyester is 45°C, the maximum washing temperature of wool fabric is 40°C, etc. When the washing device obtains the material information, it will automatically output the corresponding temperature value. When the clothing includes multiple materials, the lowest temperature can be used as the third washing temperature.

[0080] S1046: Compare the value of the third washing temperature with the temperature value corresponding to the one with a higher confidence level, and use the one with a lower value as the final washing temperature.

[0081] In one scenario, the text information of the washing label of the target clothing contains both material information and temperature information, and the final washing temperature will be determined through steps S1041-S1046. For example, through steps S1041-S1043, it is obtained that the temperature corresponding to the one with a higher confidence is "washing temperature below 50°C", and the material of the target clothing determined in step S1044 is "fabric 100% polyester", then the third washing temperature is "washing temperature below 45°C", at this time, correction is performed according to step S1046, and the final washing temperature is obtained as "washing temperature below 45°C". That is, in the control method of the present application, the correction of steps S1041-S1043 uses the one with a higher confidence as the preliminary reference value, and the correction of steps S1044-S1046 uses the one with a lower washing temperature as the final reference value, so as to calibrate the final washing temperature.

[0082] By adopting the above steps, the reference temperature values ​​obtained through multiple identification paths are compared and screened respectively. Specifically, the first comparison and correction takes the one with higher confidence as the preliminary reference value, and the second comparison and correction takes the one with lower temperature as the final reference value. In this way, the error rate of the identification result can be reduced, thereby further improving the identification accuracy.

[0083] Reference Figure 4 As another implementation of the present application, when the text information of the target laundry label does not include temperature information but only includes material information, the control method will omit steps S1041-S1043, that is, in step S104, "determining the final washing temperature according to the first washing temperature" includes:

[0084] S1044: Determine the material information of the target clothing according to the text information.

[0085] S1045: Determine a third washing temperature of the target clothing according to the material information.

[0086] S1047: Compare the value of the third washing temperature with the value of the first washing temperature, and use the lower value as the final washing temperature.

[0087] With the above Figure 3 The control method described in is different in that, compared with step S1046, step S1047 here directly compares the value of the third washing temperature determined according to the material information with the value of the first washing temperature determined according to the graphic comparison result, and then uses the lower value as the final washing temperature.

[0088] The present application also discloses a washing device, which includes a processor and a storage device, wherein the storage device is suitable for storing a plurality of program codes, and the program codes are suitable for being loaded and run by the processor to execute the control method described in any of the above embodiments. The washing device in the present application can be a drum washing machine, a pulsator washing machine, etc.

[0089] It should be noted that the above-mentioned processor can be a central processing unit, a microprocessor, a digital signal processor or any other suitable processor, which can be implemented in software, hardware or a combination of the two. Such adjustments to the processor form and application level do not deviate from the principles and scope of this application.

[0090] Similarly, the above-mentioned storage device can be any suitable medium that can store program codes, such as a hard disk, a flash memory, a read-only memory, a random access memory, etc., and the present application does not impose any limitation on its form.

[0091] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
