[0054] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0055] A laundry dryer is generally an auxiliary treatment device after laundry, which is mainly used to remove the moisture remaining after laundry, so that the laundry reaches a dry degree that can be worn, the time length of drying the laundry through airing can be saved, or the problem that the laundry cannot be dried due to too much rainy weather can be solved.

[0056] However, the user is generally fixed in the heating time length and the heating temperature when using the function of the dryer. The drying function is too single, which can cause damage to the laundry due to the overlong drying time or the overhigh drying temperature in the case that the water content in the laundry is different.

[0057] Based on the above technical problem, the present application provides a control method of a dryer, which can include first acquiring laundry spectrum data of laundry to be dried detected by a spectrum sensor, then determining a laundry attribute of the laundry to be dried according to the laundry spectrum data, then determining a target drying parameter corresponding to the laundry attribute, and finally drying the laundry to be dried according to the target drying parameter. Thus, the laundry attribute can be determined through the spectrum characteristics of the laundry to be dried, so that the laundry is dried according to the drying parameter associated with different laundry attributes, which not only enriches the laundry drying function of the dryer, but also reduces the drying damage to the laundry with different laundry attributes.

[0058] Reference Figure 1 is shown, which shows an electrical connection structure of a dryer provided by an embodiment of the present application. The dryer can include a controller 100 and a spectrum sensor 101 electrically connected to the controller 100. The spectrum sensor 101 is installed inside a drying cavity of the dryer, and is used to detect laundry spectrum data of laundry to be dried in the drying cavity and transmit the laundry spectrum data to the controller 100.

[0059] The dryer further includes a heating device 102 electrically connected to the controller 100. The controller 100 can determine a drying temperature required for the heating device 102 to operate through the laundry spectrum data.

[0060] The dryer provided by the embodiment of the present application further comprises the control device provided by any one of the embodiments of the present application, wherein the dryer can be a device only having a clothes drying function, or a device having a clothes washing function and a clothes drying function (which can also be referred to as a washing-drying integrated machine). No more limitation is made herein.

[0061] Referring to Figure 2 , a control method of a dryer is shown, and the method can comprise:

[0062] S201, obtaining clothes spectrum data of clothes to be dried detected by a spectrum sensor.

[0063] S202, determining a clothes attribute of the clothes to be dried according to the clothes spectrum data.

[0064] In the embodiment of the present application, the clothes attribute of the clothes to be dried is different, and the corresponding clothes spectrum data also has differences. Therefore, after obtaining the clothes spectrum data detected by the spectrum sensor 101, the controller 100 can determine the clothes attribute of the clothes to be dried according to the spectrum characteristics distributed in the clothes spectrum data. The clothes attribute refers to the physical characteristics of the clothes to be dried which can be analyzed by spectrum characteristics. For example, the clothes attribute can at least include a material attribute. For example, the material attribute includes but is not limited to cotton, hemp, wool and silk, and the material attribute can also be a small category of material based on the above-mentioned large categories of material, for example, for wool material, it can also include fine wool, long wool and coarse wool, etc. The person skilled in the art can determine the division of the corresponding material attribute according to the fabrics of the clothes on the market, and no more limitation is made herein.

[0065] In some embodiments, for cotton clothes, the surface of cotton fiber is relatively rough, and the reflection ability to light is relatively strong. Therefore, the cotton clothes show a relatively high reflectivity in the clothes spectrum data. For hemp clothes, hemp fiber has strong hygroscopicity and strong light absorption. Therefore, the hemp clothes show a relatively high absorption rate in the clothes spectrum data. For wool clothes, wool fiber has a natural curly shape and strong light scattering. Therefore, the wool clothes show a relatively high scattering rate in the clothes spectrum data. Therefore, the material attribute of the clothes to be dried can be inferred according to the reflection, absorption and scattering characteristics of the clothes to be dried shown in the clothes spectrum data. As Figure 3 shown, so as to display on the display page on the interactive terminal after identifying the material attribute of the clothes.

[0066] In some embodiments, the clothing attribute can further include a material attribute and a color attribute. That is, in addition to the material attribute, the color of the clothes to be dried can also be identified through the clothes spectrum data. In this case, the color attribute of the clothes to be dried can be determined through the spectral distribution data of the light reflected by the surface of the clothes included in the clothes spectrum data.

[0067] S203, determining a target drying parameter corresponding to the clothing attribute.

[0068] In the embodiments of the present application, a mapping relationship between the drying parameters and the clothing attributes can be pre-set, so that after the clothing attribute is determined, the target drying parameter corresponding to the clothing attribute can be determined based on the mapping relationship. The target drying parameter can be understood as the starting parameter when the clothes are dried. In this case, the drying parameters can include the drying time and the drying temperature.

[0069] In some embodiments, clothes made of wool usually need a longer drying time because wool fibers have high moisture absorption and warmth retention. Generally, the drying time of wool clothes is about 45 minutes to 1 hour, and clothes made of wool are prone to shrinkage and deformation when heated, so the drying temperature usually needs to be between 30-40℃. For example, the drying time of clothes to be dried corresponding to wool material can be 45min, 50min, and 60min, etc.; the drying temperature of clothes to be dried corresponding to wool material can be 30℃, 35℃, and 40℃, etc. Those skilled in the art can select appropriate drying time and drying temperature according to actual test results to obtain the target drying parameter corresponding to wool material, which will not be limited here, for example, the target drying parameter corresponding to wool material is: drying time 50min; drying temperature 35℃. Referring to FIG. 2, after the target drying parameter is determined, the display page on the interactive terminal is displayed. Figure 3

[0070] In some embodiments, clothes made of silk are prone to fiber breakage and are relatively light and thin, so the drying time can usually be 20-30min; and similar to clothes made of wool, they are prone to shrinkage and deformation when heated. Therefore, the drying temperature of clothes to be dried corresponding to silk material can be 30℃, 35℃, and 40℃, etc.; the drying time of clothes to be dried corresponding to silk material can be 20min, 25min, and 30min, etc. Those skilled in the art can select appropriate drying time and drying temperature according to actual test results to obtain the target drying parameter corresponding to silk material, which will not be limited here, for example, the target drying parameter corresponding to silk material is: drying time 20min; drying temperature 35℃.

[0071] ​In some embodiments, the cotton clothes have good heat resistance, and can be quickly dried at a medium-high temperature range of 60-70℃, but attention should be paid to avoid over-drying, i.e., the drying time can be controlled to be relatively short (20-30 min) to avoid causing the clothes to shrink or deform, etc. Thus, the drying temperature of the clothes corresponding to the cotton material to be dried can be 60℃, 65℃, and 70℃, etc. The drying time of the clothes corresponding to the cotton material to be dried can be 20 min, 25 min, and 30 min, etc. A person skilled in the art can select appropriate drying time and drying temperature according to actual test results to obtain target drying parameters corresponding to the cotton material, which are not limited herein, for example, the target drying parameters corresponding to the cotton material are: drying time 25 min; drying temperature 70℃.

[0072] In some embodiments, the synthetic fiber material (such as polyester, nylon) is sensitive to heat and is easily damaged by heat, and even can easily catch fire and melt, etc. Therefore, the drying time needs to be controlled to be relatively short, for example, fluctuating around 20 min, and the drying temperature needs to be selected to be relatively low, for example, in a temperature range of 40-50℃. Thus, the drying temperature of the clothes corresponding to the synthetic fiber material to be dried can be 40℃, 45℃, and 50℃, etc. The drying time of the clothes corresponding to the synthetic fiber material to be dried can be 20 min, 22 min, and 18 min, etc. A person skilled in the art can select appropriate drying time and drying temperature according to actual test results to obtain target drying parameters corresponding to the synthetic fiber material, which are not limited herein, for example, the target drying parameters corresponding to the synthetic fiber material are: drying time 20 min; drying temperature 40℃.

[0073] S204, drying the clothes to be dried according to the target drying parameters.

[0074] In the embodiments of the present application, after the target drying parameters are determined, the controller 100 can control the heating device 102 to heat to the drying temperature specified by the target drying parameters, and dry the clothes to be dried according to the drying time in the target drying parameters. Thus, the clothes attribute is determined by the spectral characteristics of the clothes to be dried, so that the clothes can be dried according to the drying parameters associated with different clothes attributes, which not only enriches the clothes drying function of the dryer, but also reduces the drying damage to clothes with different clothes attributes.

[0075] Referring to Figure 4 , another control method of a dryer is shown, which can include:

[0076] S401, obtaining clothes spectral data of clothes to be dried detected by a spectral sensor.

[0077] S402, determine a spectrum distribution image of the clothes to be dried according to the clothes spectrum data.

[0078] In the embodiment of the present application, the clothes properties of the clothes to be dried are different, and the corresponding clothes spectrum data also has differences. Therefore, after the clothes spectrum data detected by the spectrum sensor 101 is obtained, the controller 100 can determine the spectrum distribution image of the clothes to be dried according to the spectrum characteristics distributed in the clothes spectrum data. Therefore, the spectrum distribution image is used to represent the spectrum characteristics of the clothes to be dried.

[0079] S403, input the spectrum distribution image into a preset attribute classification model for identification to determine the clothes property of the clothes to be dried.

[0080] In the embodiment of the present application, the clothes property refers to the physical characteristics of the clothes to be dried which can be analyzed by spectrum characteristics. The attribute classification model is used to classify the spectrum characteristics in the spectrum distribution image, so as to obtain the clothes property of the clothes to be dried.

[0081] In some embodiments, the clothes property can at least include a material property. For example, the material property includes but is not limited to cotton, hemp, wool and silk, and the like. Correspondingly, the material property can also be a small category of material divided on the basis of the above-mentioned large categories of material, for example, for wool material, it can also include fine wool, long wool and coarse wool, etc. Those skilled in the art can determine the division of the corresponding material property according to the fabrics of the clothes on the market, which is not limited here.

[0082] In some other embodiments, the clothes property can also include a material property and a color property. That is, in addition to the material property, the color of the clothes to be dried can also be identified by the clothes spectrum data. Among them, the color property of the clothes to be dried can be determined by the spectrum distribution data of the light reflected by the clothes surface included in the clothes spectrum data.

[0083] In an alternative embodiment of the present application, the attribute classification model can be a convolutional neural network, and the method can further include a training step of the attribute classification model, which includes:

[0084] Obtain a plurality of spectrum sample images corresponding to different clothes properties, and the spectrum sample images are labeled with real clothes properties.

[0085] Input a plurality of spectrum sample images into the attribute classification model for classification and identification to obtain corresponding predicted clothes properties.

[0086] According to the real clothes attribute and the predicted clothes attribute, a loss function value of the attribute classification model is determined.

[0087] According to the loss function value, a model parameter of the attribute classification model is adjusted, and a trained attribute classification model is determined.

[0088] In the embodiment of the application, all clothes attributes corresponding to the spectral sample images are obtained in advance, and the spectral sample images are pre-labeled with the real clothes attributes to which they belong. A spectral sample image is input into the attribute classification model for classification and recognition, so as to obtain the clothes attribute predicted by the attribute classification model based on the spectral sample image. Then, according to the real clothes attribute and the predicted clothes attribute, the loss function value of the attribute classification model is determined, and finally, according to the loss function value, the parameter of the attribute classification model is adjusted. After the parameter adjustment, a spectral sample image is input into the attribute classification model after the parameter adjustment for classification and recognition, and the clothes attribute predicted by the attribute classification model based on the spectral sample image is continuously obtained. Then, according to the real clothes attribute and the predicted clothes attribute, the loss function value of the attribute classification model is determined, and finally, according to the loss function value, the parameter of the attribute classification model is adjusted. In this way, the trained attribute classification model is finally obtained. For example, when the loss function value decreases slowly, for example, the loss function value corresponding to 100 comparison results decreases within 1‰. The parameter adjustment of the attribute classification model is stopped, and the model at this time is determined as the trained attribute classification model.

[0089] S404, matching the initial drying parameter associated with the clothes attribute.

[0090] In the embodiment of the application, the mapping relationship between the drying parameter and the clothes attribute can be pre-set, so that after the clothes attribute is determined, the target drying parameter corresponding to the clothes attribute can be determined based on the mapping relationship. The target drying parameter can be understood as the starting parameter for clothes drying. The drying parameter can include the drying time and the drying temperature. In this application, in order to improve the user experience and enrich the clothes drying function of the drying machine, the user can adjust the drying parameter based on the user terminal before the drying program is started, or the adjustment of the drying parameter can be realized based on the temperature and humidity of the clothes to be dried in the drying cavity. Therefore, the initial drying parameter can be determined in advance, and the initial drying parameter can be updated to determine the target drying parameter.

[0091] In some optional embodiments, when the clothing attribute only includes the material attribute, a material mapping relationship between the drying parameter and the material attribute can be preset, so that after the material attribute is determined, the initial drying parameter associated with the material attribute can be matched based on the material mapping relationship.

[0092] In some other optional embodiments, when the clothing attribute includes the material attribute and the color attribute, an initial drying rule associated with the material attribute can be matched, and an initial drying parameter associated with the color attribute can be matched from the initial drying rule. The initial drying rule can include a plurality of clothing drying parameters corresponding to different color attributes of the same material attribute. Thus, when the initial drying parameter is determined, the initial drying rule associated with the material attribute can be matched first, and then the color attribute is used to match the initial drying rule, so that the initial drying parameter associated with the color attribute can be matched from the initial drying rule.

[0093] S405, obtaining a correction parameter and updating the initial drying parameter according to the correction parameter.

[0094] In the embodiments of the present application, the correction parameter can be generated by a user based on an editing operation of a user terminal. For example, the correction parameter can include a set drying time. In addition, the correction parameter can also be generated by the controller 100 based on the temperature and humidity data detected by the temperature and humidity sensor. Correspondingly, the correction parameter can also include temperature data and humidity data. Thus, the initial drying parameter can be updated according to the correction parameter, so that the clothing drying function of the dryer can be enriched, the drying damage to the clothing with different clothing attributes can be further reduced, and the user experience can be improved.

[0095] In some optional embodiments of the present application, the method further includes:

[0096] A control page including a control control is provided to the user terminal.

[0097] The correction parameter fed back by the user terminal is received, the correction parameter being determined according to the triggering of the control control, and the correction parameter including a set drying time.

[0098] In the embodiments of the present application, the user terminal can include a mobile user terminal and a user interactive terminal, etc. The mobile user terminal is loaded on a mobile device such as a mobile phone, a tablet computer and a computer, and the user interactive terminal is loaded in the dryer. Referring to Figure 5The control page is displayed on the user terminal, and the control page further includes a control control. Based on an editing operation of the control control by the user, the controller 100 triggers the user terminal to feed back a correction parameter. The correction parameter can include a set drying time manually set by the user.

[0099] Accordingly, the set drying time can be used to update the drying time in the initial drying parameter. For example, the set drying time can be used as the drying time in the updated initial drying parameter. For another example, whether to update the drying temperature in the initial drying parameter can be determined according to a time difference between the set drying time and the drying time in the initial drying parameter.

[0100] In an example, a first time threshold can be preset for the time difference. The first time threshold is used to evaluate whether the set drying time can reach a dryness required by the clothes to be dried at the initial drying temperature of the initial drying parameter. The first time threshold can be 5 minutes, 10 minutes, etc. A person skilled in the art can determine a specific first time threshold according to the drying test results of clothes of different material properties, which is not limited herein.

[0101] In a case where the time difference is greater than or equal to the first time threshold, it is determined to update the drying temperature in the initial drying parameter. For example, the first time threshold is 10 minutes, and the initial drying parameter corresponding to the wool material is: drying time 50 minutes; drying temperature 35℃. The set drying time is 40 minutes, and the time difference is equal to the first time threshold. It is determined that the set drying time cannot reach the dryness required by the wool clothes at the initial drying temperature. Accordingly, in a case where the set drying time is too short, the initial drying temperature can be updated according to the suitable drying temperature of the wool clothes. For example, the initial drying temperature can be updated to 40℃.

[0102] In order to avoid that the set drying time set by the user is too short, the control control on the control page can be set with an adjustment limit range of the drying time. The adjustment limit range can be determined based on the suitable drying temperature range and the drying time of different material properties.

[0103] In some alternative embodiments of the invention, the drying parameters can be adjusted based on the temperature and humidity of the clothes to be dried within the drying chamber. Correspondingly, the dryer may also include a temperature sensor and a humidity sensor, and the calibration parameters include the humidity and temperature of the clothes. After determining the initial drying parameters for the clothes to be dried, the drying temperature and / or drying time in the initial drying parameters can be updated based on the humidity and temperature of the clothes.

[0104] In this embodiment of the invention, considering that the initial drying parameters, including the calibrated temperature and humidity, may differ from the actual operating conditions of the dryer—for example, the calibrated temperature is typically 25°C, and the calibrated humidity is typically between 40% and 60%—the temperature of the clothes placed in the drying chamber may be relatively high after the dryer has just finished drying the clothes once. Alternatively, the moisture and humidity content of the clothes before and after wringing may differ. Therefore, the drying temperature in the initial drying parameters can be updated based on the clothing humidity and temperature. Alternatively, the drying time in the initial drying parameters can be updated. The clothing humidity is directly proportional to the drying temperature, and the clothing temperature is inversely proportional to the drying temperature (for example, when the clothing temperature is high, the clothes are in a pre-drying state in the drying chamber before the dryer starts the drying program). If the drying time remains unchanged, the drying temperature can be slightly reduced. The clothing humidity and drying time are directly proportional, and the clothing temperature and drying time are inversely proportional, and so on, to update the initial drying parameters.

[0105] S406. Use the updated initial drying parameters as the target drying parameters.

[0106] S407. Dry the clothes to be dried according to the target drying parameters.

[0107] In this embodiment of the invention, the updated initial drying parameters are used as the target drying parameters. The controller 100 can control the heating device 102 to heat to the drying temperature specified by the target drying parameters and dry the clothes to be dried according to the drying time specified in the target drying parameters. Thus, by using the spectral characteristics of the clothes to be dried, the clothing properties can be determined, allowing for drying based on drying parameters associated with different clothing properties. This not only enriches the drying function of the dryer but also reduces drying damage to clothes with different properties.

[0108] S408. Monitor the drying status of the clothes to be dried during the drying process.

[0109] S409. Match auxiliary drying parameters associated with the current drying status.

[0110] S410, control the auxiliary drying equipment of the dryer, run according to the auxiliary drying parameter.

[0111] In the embodiment of the application, the drying state of the clothes to be dried can be monitored during the drying process of the clothes to be dried, and the drying state can be divided into states in time sequence, for example, the drying state can include a preheating state in a first time period, a destaticizing state in a second time period, a clothes fluffing state in a third time period, and an air exchange state in a fourth time period, etc.

[0112] For example, in the first time period, the clothes rotating device can be driven to rotate, so that the clothes to be dried can be uniformly heated, and the problem of unsatisfactory drying effect caused by partial overheating or overcooling of the clothes can be reduced. In the second time period, the steam generating device can be started to release high-temperature steam, so that static electricity and wrinkles of the clothes to be dried can be removed. In the third time period, the pressurizing device can be started to pressurize the drying cavity, and the clothes can be simulated to be beaten to make the clothes to be dried more fluffy. In the fourth time period, the air exchange device can be started to exchange air inside and outside the drying cavity, so that the clothes to be dried can be naturally cooled, and wrinkles can be further reduced.

[0113] The clothes rotating device, the steam generating device, the pressurizing device, and the air exchange device all belong to the auxiliary drying equipment of the surgical dryer, so that the auxiliary drying parameter associated with the current drying state can be matched according to the drying state of the clothes to be dried during the drying process. The auxiliary drying parameter can be understood as the running parameter of the auxiliary drying equipment. The auxiliary drying parameter can be pre-set.

[0114] For example, for the clothes rotating device, the auxiliary drying parameter thereof can include the rotating speed and the rotating time length, for the pressurizing device, the auxiliary drying parameter thereof can include the pressure value and the pressurizing interval, and so on. In the clothes to be dried in different drying states, the controller 100 can control the related auxiliary drying equipment of the dryer to run according to the auxiliary drying parameter. Thus, the drying effect of the clothes to be dried can be improved, and the user experience can be improved.
