[0061] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0062] Secondly, it should be noted that in the description of the embodiments of the present invention, the terms "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0063] In addition, it should be noted that in the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] With the development of economy and the improvement of people's living standards, washing and drying equipment has been more widely used. Washing and drying equipment can dry clothes after the washing stage, so that the clothes reach the dryness required by users, saving users the time of drying clothes after washing.

[0066] At present, the washing and drying linkage of washing and drying equipment needs to be completed manually by the user. When the washing machine finishes washing, the user selects the drying program, and then the dryer executes the drying program to dry the clothes. However, the time when the user selects the drying program is limited. For example, when the washing machine is in the washing operation state and the remaining washing time is less than the preset time, the drying program cannot be selected. In addition, the dryness of the clothes dried in the prior art is the default dryness of the program, which cannot achieve the best drying effect for different types of clothes, and the manual completion of the washing and drying linkage by the user also reduces the user experience.

[0067] Therefore, the art needs a new laundry equipment control method, device and equipment to solve the above problems.

[0068] The present application provides a laundry equipment control method. Before the end of the washing stage of the laundry equipment, if it is determined that the clothes need to be dried, the dryer is controlled to preheat and the laundry equipment to increase the dehydration speed. After the washing stage of the laundry equipment is finished, the dryer is controlled to dry the clothes until the humidity in the drum reaches or is less than the target humidity and lasts for a certain period of time. Finally, according to the time the dryer dries the clothes to the target humidity and lasts for a certain period of time, the drying coefficient corresponding to the target dryness of the type of clothes in the drum is obtained; the drying time is obtained according to the drying coefficient, and the clothes are dried within the drying time to reach the target dryness, so that different types of clothes can achieve the best drying effect.

[0069] The principles and features of the embodiments of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present invention and are not used to limit the scope of the embodiments of the present invention.

[0070] Figure 1 is a flow chart of a first embodiment of a laundry equipment control method provided by the present invention; Figure 1 As shown, the laundry equipment control method specifically includes the following steps:

[0071] S101: Before the washing stage of the laundry machine ends, if it is determined that the clothes are to be dried, the dryer is controlled to perform preheating, and the laundry machine is controlled to increase the dehydration speed.

[0072] The laundry device includes a washing machine and a dryer. The situation in which it is determined that the clothes need to be dried may be, for example: the laundry device receives a user's instruction to dry the clothes before the washing program starts, that is, the user sets the clothes to be dried after washing before washing; the situation in which it is determined that the clothes need to be dried may also be: the laundry device determines through the Internet of Things function that it is not suitable to dry the clothes at present.

[0073] The method for judging whether the situation is not suitable for drying clothes may be, for example: the laundry machine obtains the weather condition, temperature and humidity of the environment in which the laundry machine is located during the laundry time period through the Internet of Things function; if the weather condition of the environment in which the laundry machine is located is obtained to be rainy, foggy, dusty, etc., then it is judged to be not suitable for drying clothes; in addition, if it is obtained that the geographical location of the laundry machine is coastal (the straight-line distance to the sea is less than a preset value) or the temperature and humidity of the place are high (for example, low latitude or subtropical climate, etc.), and it is detected that the temperature and humidity in the room where the laundry machine is located are high, then it is judged to be not suitable for drying clothes.

[0074] After determining that the clothes need to be dried in the above manner, the washing machine automatically matches the drying device under the same home network. The drying device can be, for example, a dryer of an integrated washer-dryer, a combined washer-dryer, or a drying area of ​​a washer-dryer, etc. The washing device turns on the dryer by automatically starting the washing and drying linkage function, Bluetooth pairing, or detecting the drying signal of the dryer corresponding to the washing process signal uploaded by the washing machine on the home network.

[0075] The method of controlling the dryer to perform preheating may specifically be: the laundry machine controls the dryer to start preheating n minutes before the end of washing, the n minutes being set as adjustable in the program, and the n minutes may be, for example, 15 minutes; at the same time, the dryer with an independent fan starts auxiliary heating, a compressor, and an independent fan, and the dryer without an independent fan only starts auxiliary heating and a compressor to achieve preheating; in addition, the preheating of the dryer stops when the washing machine stops after washing, and the preheating time of the dryer is limited to a minimum of 15 minutes and a maximum of 20 minutes, so as to prevent long-term preheating when the washing machine is still running or the clothes are not transferred into the dryer in time.

[0076] The method of controlling the laundry device to increase the dehydration speed may specifically be: controlling the washing machine in the laundry device to adjust the dehydration speed to the highest dehydration speed of the current washing program to achieve the best dehydration effect, further saving the time for subsequent drying of clothes in the dryer.

[0077] S102: After the washing stage of the laundry device is completed, the dryer is controlled to perform drying until the humidity in the dryer drum reaches the target humidity, a first time duration for heating to the target humidity is obtained, and drying is continued for a second time duration, wherein the second time duration and the target humidity are determined according to the type of clothing.

[0078] In this step, the clothing type is one of a ready-to-wear type, a ready-to-iron type, or a storage type; the classification method of the clothing type may be, for example:

[0079] The laundry device obtains local climate information or temperature information through its own Internet of Things function to determine whether the clothes in the drum are seasonal clothes or clothes for changing seasons. For example, if the laundry device obtains through the Internet of Things that the current season is summer or the temperature is higher than 30°C, then down jackets, woolen sweaters and other clothes are judged as clothes for changing seasons, while short-sleeved shirts, shorts and other clothes are judged as clothes for the current season. The laundry device can also determine whether the clothes in the drum are seasonal clothes or clothes for changing seasons by detecting the thickness of the clothes and combining the obtained climate information or temperature information to make a judgment, and the present invention does not impose any limitation on this.

[0080] The ready-to-wear clothing may be, for example, clothing that the user wears next to the skin, bed sheets, bath towels, towels, and other clothing that are close to the skin. At the same time, the seasonal clothing may also be classified as the ready-to-wear clothing. The ready-to-iron clothing may be, for example, suits, shirts, woolen coats, and other types of clothing that are prone to wrinkling. In addition, clothing made of materials such as chemical fibers and carpets are prone to static electricity due to their low moisture content, and are also classified as the ready-to-iron clothing. At the same time, the seasonal clothing may also be classified as the ready-to-iron clothing depending on the situation. The storage clothing may be, for example, seasonal clothing. The seasonal clothing is classified as the storage clothing because it does not need to be worn at the moment.

[0081] The target humidity is the humidity in the drum of the dryer when different types of clothes preset in the laundry machine are basically dried. The target humidity corresponding to the ready-to-wear type and the storage type clothes is equal, and the target humidity corresponding to the ready-to-iron type clothes is greater than the target humidity corresponding to the storage type clothes. The target humidity corresponding to the ready-to-wear type and the storage type clothes may be, for example, 350, and the target humidity corresponding to the ready-to-iron type clothes may be, for example, 1350. It can be understood that since the ready-to-iron type clothes are prone to wrinkles after being dried and need to be ironed, their target humidity should be greater than the target humidity of the storage type and the ready-to-wear type clothes.

[0082] The second time length is the time length for which the clothes dryer continues to dry after the clothes dryer reaches or is less than the target dryness. The purpose of setting the second time length is to ensure that the clothes humidity is maintained near the target humidity. When the humidity value meets the time length requirement, the clothes state is judged to be dry, and the next step is to enter the drying stage. The second time lengths corresponding to the ready-to-wear type clothes and the ready-to-iron type clothes are equal, and the second time length corresponding to the storage type clothes is greater than the second time lengths corresponding to the ready-to-wear type and the ready-to-iron type clothes. The second time lengths corresponding to the ready-to-wear type clothes and the ready-to-iron type clothes can be, for example, 30s, and the second time length corresponding to the storage type clothes can be, for example, 60s. It can be understood that the storage type clothes are not seasonal clothes, so they need to be stored in the wardrobe after being dried. In order to ensure that they can achieve the drying effect that can be stored, the storage type clothes have a higher dryness judgment requirement, and the corresponding second time length is greater than the second time lengths corresponding to the ready-to-wear type and the ready-to-iron type clothes.

[0083] S103: After the second time period ends, a third time period is obtained according to the first time period and the target drying coefficient corresponding to the target dryness, and the dryer is controlled to dry the clothes for the third time period so that the clothes reach the target dryness, wherein the target dryness is the dryness of the clothes determined according to the type of clothes.

[0084] Among them, after the second time period ends, the clothes in the dryer drum are basically in a dried state, however, there may still be some wrinkles or areas with thicker materials in the clothes in the dryer drum that are not completely dried, and the optimal drying effect corresponding to this type of clothes is not achieved. In order to solve the above problem, the present application is provided with an additional drying process for the clothes in the dryer drum after the second time period ends, so that the clothes in the dryer drum are completely dried and achieve the optimal drying effect.

[0085] In this step, the duration of drying the laundry in the drum is the third duration, and the third duration is obtained according to the first duration and the target drying coefficient corresponding to the target dryness. The target drying coefficient is used as a calculation parameter when calculating the third duration.

[0086] The said making the clothes in the dryer drum achieve the best drying effect is to make the clothes in the dryer drum reach the target dryness corresponding to the type of clothes. The target dryness is the moisture content corresponding to different types of clothes. It can be understood that the target dryness corresponding to the ready-to-wear type clothes is greater than the target dryness corresponding to the ready-to-iron type clothes, and less than the target dryness corresponding to the storage type clothes. The moisture contents corresponding to the target dryness of the storage type clothes, the ready-to-wear type clothes, and the ready-to-iron type clothes are 0%-2%, 2%-6%, and 6%-12% respectively. Since the ready-to-iron type clothes are prone to wrinkles, they need to be ironed after drying, so the moisture content of the ready-to-iron type clothes is the highest. Since the storage type clothes do not need to be worn at present, they need to be put into the wardrobe for storage, so the moisture content of the storage type clothes is the lowest. The ready-to-wear type clothes can be worn after drying and are close to the skin, so the moisture content of the ready-to-wear type clothes is in the middle among the above three types of clothes.

[0087] The laundry control method provided in this embodiment controls the dryer to preheat and controls the laundry machine to increase the dehydration speed if it is determined that the clothes need to be dried before the washing stage of the laundry machine ends. After the washing stage of the laundry machine ends, the dryer is controlled to dry the clothes until the humidity in the dryer drum reaches the target humidity and lasts for a certain period of time, and the target humidity and the time are determined according to the type of clothes. Finally, the drying coefficient corresponding to the target dryness of the clothes is obtained according to the total time for the dryer to dry the clothes to the target humidity and last for a certain period of time, and the drying time of the clothes is obtained. The clothes are dried to reach the target dryness, and the target dryness of different types of clothes is different.

[0088] This method solves the problem in the prior art that dryers cannot achieve the best drying effect for different types of clothes, and that users manually complete the washing and drying linkage, which reduces the user experience. It matches the most suitable drying target dryness for different types of clothes, determines the additional drying coefficient and obtains the additional drying time of the clothes based on the additional drying coefficient, and after drying the clothes to reach the target humidity, it performs additional drying on the clothes to make the clothes reach the target dryness and achieve the best drying effect for the clothes.

[0089] Figure 2 is a flow chart of a second embodiment of a laundry equipment control method provided by the present invention; Figure 2 exist Figure 1 Based on this, the method of obtaining the target baking coefficient and baking time is described in detail, such as Figure 2 As shown, the method includes:

[0090] S201: In the cold air stage before the dryer heats and dries the clothes, the weight of the clothes in the drum and the current ambient temperature are obtained.

[0091] Among them, the second time duration is the time duration for which the dryer continues to dry the clothes after the clothes reach the target humidity. During the second time duration, the humidity in the dryer drum is maintained near the target humidity. The purpose of setting the second time duration is to accurately judge the dryness so that the clothes can achieve the ideal drying effect in the subsequent drying stage, that is, to achieve the moisture content of the corresponding type of clothes.

[0092] After the second time period, the clothes in the dryer drum are basically dried. However, some wrinkles or thicker areas of the clothes in the dryer drum may not be completely dried, and the best drying effect corresponding to the type of clothes is not achieved, that is, the moisture content corresponding to the type of clothes is not achieved. In order to make the clothes in the dryer drum reach the moisture content corresponding to the type of clothes, the present application is provided to perform an additional drying process on the clothes in the dryer drum after the second time period is over.

[0093] It is understandable that the drying time of clothes is affected by the weight of clothes in the dryer drum and the temperature of the environment in which the washing machine is located. For example, if the temperature of the environment in which the washing machine is currently located is below zero, the drying time of down jackets with thicker materials is longer in the drying stage. If the indoor temperature of the environment in which the washing machine is currently located is in a high temperature environment commonly seen in summer, the drying time of short-sleeved shirts that are lighter and easier to dry is correspondingly shorter. Since the ambient temperature remains basically unchanged and in order to ensure that the clothes are completely dried, it is necessary to obtain the weight of clothes in the dryer drum and the current ambient temperature during the cold wind stage before heating and drying the clothes for the first time period and the second time period, so as to obtain the drying time adapted to the current conditions in the subsequent steps after the second time period ends.

[0094] S202: Obtain a target drying coefficient according to the weight of the laundry in the drum, the current ambient temperature and a basic drying coefficient corresponding to the target dryness.

[0095] The basic drying coefficient and the target drying coefficient are parameters for obtaining the drying time of the dryer in the drying stage. The basic drying coefficient is a basic coefficient preset by the laundry machine according to the general drying conditions of different types of clothes, and different types of clothes have different corresponding basic drying coefficients. The drying time calculated by the basic drying coefficient can make the clothes basically reach the moisture content corresponding to their type of clothes after the drying stage.

[0096] However, due to the different environments in which the laundry equipment is located and the differences in the materials of the clothes, it is necessary to adjust the basic drying coefficient in combination with the weight of the clothes in the drum and the current ambient temperature to obtain a target drying coefficient that is suitable for the current conditions. The basic drying coefficient is negatively correlated with the target dryness. The principle is: when obtaining the drying time (third time), the quotient of the total time of the dryer drying the clothes to the target humidity and continuously drying at the target humidity for a certain period of time and the adjusted basic drying coefficient (target drying coefficient) is taken as the drying time. When the basic drying coefficient is larger, the calculated drying time is shorter, and the moisture content of the clothes after drying is higher and the dryness is lower.

[0097] S203: Obtain a third duration according to the first duration, the second duration, and the target baking coefficient.

[0098] The third time duration is the drying time duration of the dryer in the drying stage. After the clothes in the dryer drum are dried for the first time duration and the second time duration, they have basically reached a dry state. By referring to the first time duration, the second time duration and the target drying coefficient, the drying time duration for the clothes in the dryer drum to reach the target dryness can be obtained, that is, the third time duration.

[0099] The laundry equipment control method provided in the present embodiment obtains the weight of the laundry in the drum and the ambient temperature of the current environment of the laundry equipment during the cold air stage before the dryer heats and dries the laundry, obtains the target drying coefficient based on the weight of the laundry in the drum, the ambient temperature of the current environment of the laundry equipment and the basic drying coefficient corresponding to the target dryness of the type of laundry in the drum, and finally obtains the drying time of the laundry dryer based on the time it takes for the dryer to dry the laundry to reach the target humidity and last for the first time and the target drying coefficient.

[0100] This method solves the problem in the prior art that dryers cannot achieve the best drying effect for different types of clothes. After the dried clothes reach the target humidity corresponding to their type of clothes, the target drying coefficient corresponding to the type of clothes in the drum is obtained and the drying time is obtained. The clothes are dried within the drying time so that the clothes reach the target dryness corresponding to their type, so that different types of clothes can achieve the best drying effect.

[0101] Figure 3 1 is a flow chart of a third embodiment of a laundry equipment control method provided by the present invention; Figure 3 exist Figure 2 On this basis, the method of obtaining the target baking coefficient is described in detail, such as Figure 3 As shown, the method includes:

[0102] S301: In the cold air stage before the dryer heats and dries the clothes, the weight of the clothes in the drum and the current ambient temperature are obtained.

[0103] Among them, after the second time period ends, the clothes in the dryer drum basically reach the drying state. Due to the influence of the current weather conditions of the environment in which the washing device is located, the thickness of the clothes in the drum, etc., the clothes in the dryer drum may still have some wrinkles or areas with thicker materials that are not completely dried. In order to make the clothes in the dryer drum reach the target moisture content corresponding to its clothing type, the present application is arranged to perform an additional drying treatment on the clothes in the dryer drum after the second time period ends. It can be understood that the additional drying time of the clothes is affected by the weight of the clothes in the dryer drum and the current ambient temperature of the washing device. Since the ambient temperature remains basically unchanged and in order to ensure that the clothes are completely dried, it is necessary to obtain the weight of the clothes in the dryer drum and the current ambient temperature during the first time period and the cold wind stage before the clothes are heated and dried during the second time period, so as to obtain the additional drying time adapted to the current conditions in the subsequent steps after the second time period ends.

[0104] S302: Obtain a temperature ratio between the current ambient temperature and a preset reference temperature.

[0105] The preset reference temperature is a temperature reference value when adjusting the basic coefficient of drying and adding according to the current ambient temperature of the laundry machine. The preset reference temperature may be, for example, an ambient temperature of 25°C. If the current ambient temperature is greater than the preset reference temperature, the ratio of the current ambient temperature to the preset reference temperature is greater than 1; if the current ambient temperature is less than the preset reference temperature, the ratio of the current ambient temperature to the preset reference temperature is less than 1. By obtaining the temperature ratio of the current ambient temperature to the preset reference temperature, the basic coefficient of drying and adding may be adjusted in the ambient temperature dimension.

[0106] S303: Obtaining a weight ratio of a preset reference weight to the weight of the laundry in the drum.

[0107] The preset reference weight is the weight reference value when adjusting the basic drying coefficient according to the current weight of the laundry in the drum. The preset reference weight may be, for example, 3 kg. If the current weight of the laundry in the drum is greater than the preset reference weight, the ratio of the current preset reference weight to the weight of the laundry in the drum is less than 1. If the current weight of the laundry in the drum is less than the preset reference weight, the ratio of the current preset reference weight to the weight of the laundry in the drum is greater than 1. By obtaining the weight ratio of the preset reference weight to the weight of the laundry in the drum, the basic drying coefficient may be adjusted in terms of the weight of the laundry in the drum.

[0108] S304: Obtain a target baking coefficient according to the product of the temperature ratio, the basic baking coefficient and the weight ratio.

[0109] Among them, the method of obtaining the target drying coefficient according to the product of the temperature ratio, the basic drying coefficient and the weight ratio can be understood as adjusting the basic drying coefficient in the dimensions of ambient temperature and the weight of clothes in the drum. The adjusted basic drying coefficient is the target drying coefficient, and the target drying coefficient is adapted to the actual situation in the current clothing drying process.

[0110] For example, if the current ambient temperature is lower than the preset reference temperature, and the weight of the clothes in the drum is greater than the preset reference weight, the ratio of the current ambient temperature to the preset reference temperature is less than 1, and the ratio of the preset reference weight to the weight of the clothes in the drum is less than 1, and the calculated target drying coefficient is less than the basic drying coefficient. This situation can be, for example, in winter when drying thicker down jackets and wool sweaters. Because the basic drying coefficient is negatively correlated with the target dryness, the larger the target dryness, the smaller the basic drying coefficient, and the longer the required drying time. When the current ambient temperature is lower than the reference temperature and the weight of the clothes in the drum is greater than the preset reference weight, the required drying time is further extended. The calculated target drying coefficient is less than the basic drying coefficient and conforms to the above logic.

[0111] The laundry control method provided in this embodiment obtains the weight of the clothes in the dryer drum and the ambient temperature of the current environment of the laundry machine in the cold wind stage before the dryer heats and dries the clothes. The target drying coefficient is obtained according to the ratio of the current ambient temperature to the preset reference temperature and the ratio of the preset reference weight to the weight of the clothes in the drum multiplied by the basic drying coefficient.

[0112] This method obtains the current ambient temperature of the washing machine and the weight of the clothes in the drum, adjusts the basic drying coefficient and finally obtains the target drying coefficient. The drying time calculated by the target drying coefficient meets the drying requirements of clothes under different conditions, and finally achieves the best drying effect for different types of clothes after the drying stage.

[0113] Figure 41 is a flow chart of a fourth embodiment of a laundry equipment control method provided by the present invention; Figure 4 exist Figure 2 Based on this, the method for obtaining the baking time is described in detail, such as Figure 4 As shown, the method includes:

[0114] S401: Obtain a candidate duration according to a ratio of a sum of the first duration and the second duration to a target baking coefficient.

[0115] Among them, after the clothes in the dryer drum are dried for the first time and the second time, they have basically reached the dry state. According to the first time, the second time and the target drying coefficient, a candidate time for the clothes in the dryer drum to reach the target dryness corresponding to its type can be obtained. The specific method is: the ratio of the sum of the first time and the second time to the target drying coefficient is used as the candidate time.

[0116] S402: Determine whether the candidate duration is between a preset minimum baking duration and a preset maximum baking duration; if so, execute S403; if not, execute S404.

[0117] The preset minimum drying time is the lower limit of the drying time preset by the laundry device, to prevent the clothes from not reaching the target dryness corresponding to their clothing types after the drying stage. The preset maximum drying time is the upper limit of the drying time preset by the laundry device, to prevent the clothes from being in the drying stage for too long, resulting in excessive drying and causing the clothes to wrinkle and pill, etc., which damages the clothing material. It is determined whether the candidate time is between the preset minimum drying time and the preset maximum drying time to obtain the drying time of the current drying stage.

[0118] S403: Use the candidate duration as the third duration.

[0119] Among them, the third time length is the drying time length of the current drying stage. If the candidate time length is between the preset minimum drying time length and the preset maximum drying time length, the clothes will not reach the target dryness corresponding to their clothing type after the drying stage ends, or excessive drying will cause the clothes to wrinkle and pill, thereby damaging the clothing material. Therefore, the candidate time length is used as the third time length.

[0120] S404: The preset minimum baking time or the preset maximum baking time is used as the third time.

[0121] Among them, if the candidate time is longer than the preset maximum drying time, it is easy for the clothes to be over-dried and cause wrinkles and pilling, etc., which damages the clothing material. In order to prevent this from happening, the preset maximum drying time is used as the third time. If the candidate time is shorter than the preset minimum drying time, it is easy for the clothes to not reach the target dryness corresponding to their clothing type after the drying stage ends. Therefore, the preset minimum drying time is used as the third time.

[0122] The laundry equipment control method provided in this embodiment takes the ratio of the time it takes for a dryer to dry clothes to reach a target humidity and last for a certain period of time to the target drying coefficient as a candidate time, and then compares the candidate time with a preset minimum drying time and a preset maximum drying time, and finally obtains the drying time for the dryer to dry clothes.

[0123] This method avoids the situation where the dryer overdries or fails to reach the target dryness during the drying process of clothes by comparing the candidate time with the preset minimum drying time and the preset maximum drying time. The maximum drying time and the minimum drying time are used as the upper and lower limits of the drying time for clothes, ensuring that different types of clothes can achieve the best drying effect after the drying stage.
