[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts, including but not limited to combinations of multiple embodiments, fall within the protection scope of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0077] Washing machines have long been popularized in people's daily family lives. With the continuous upgrading of washing machines, current washing machines already have dehydration and drying functions.

[0078] Currently, the dehydration and drying of washing machines are sequentially executed according to the programs pre-stored in the controller, and the start and stop of dehydration or drying are executed in a fixed manner set by the program.

[0079] However, when there are few clothes to be washed or the materials of the clothes to be washed are different, it is very easy to have an overly long dehydration time, which not only consumes electricity but also damages the clothes, or an overly long drying time or too high a temperature, resulting in damage to the clothes. Generally speaking, there is a technical problem in the prior art that the washing machine control parameters cannot be automatically adjusted according to the actual clothes washing situation.

[0080] Regarding the above problems, the inventive concept of the present application is:

[0081] By automatically identifying the material of the clothes and the water content after washing each time when washing clothes, and combining with the user's washing mode setting to adjust the relevant parameters of dehydration or drying, such as the rotation speed of the washing tub, the power and temperature of drying, the time length of dehydration or drying, and so on. The dual effects of not damaging the clothes and saving energy and environmental protection are achieved.

[0082] The following will specifically describe the washing machine control method provided by the present application with reference to the accompanying drawings.

[0083] Figure 1 It is a schematic diagram of an application scenario of a washing machine control method provided by the present application. As Figure 1 shown, when the user puts clothes into the washing tub 101 of the washing machine 100, the sensor 102 obtains the attribute information of the clothes, such as collecting images by using a camera, and then obtaining the material of the clothes through image recognition, or reading the clothes information stored in the electronic tag on the clothes according to the radio frequency identification (RFID) technology, such as the dry weight of the clothes. Of course, the dry weight can also be obtained by the weight sensor on the washing tub. After the user inputs the selected washing mode through the panel on the washing machine 100, the controller 103 starts washing. After the washing is completed, before dehydration and / or drying, the weight sensor on the washing tub obtains the current water content weight of the clothes, and then the washing machine starts to readjust the dehydration and / or drying parameters according to the current water content weight.

[0084] And during the dehydration and / or drying process, the change of the water content is still monitored in real time, and the corresponding control parameters are continuously adjusted or corrected.

[0085] Figure 2 It is a schematic flowchart of a washing machine control method provided by an embodiment of the present application. As Figure 2 shown, the specific steps of the washing machine control method include:

[0086] S201. Obtain the attribute information of all the clothes in the washing tub, and screen out the target materials that meet the preset conditions from all the materials.

[0087] In this step, the attribute information includes: dry weight and material.

[0088] In this embodiment, at least one camera is installed at the entrance of the washing tub of the washing machine to collect images of the clothes when the user puts the clothes into the washing tub, and then the controller uses image recognition technology to identify the materials, types of the clothes, etc. At the same time, a weight sensor is also installed at the bottom of the washing tub, so that the dry weight of the clothes put into the washing tub can be obtained one by one.

[0089] In one possible implementation, an RFID (Radio Frequency Identification) electronic tag is hung on or built into each piece of clothing, and a reader / writer is installed on the washing machine. When the clothing is put into the washing machine, the reader / writer reads the clothing attribute information recorded in the electronic tag, including dry weight, material, clothing type, etc.

[0090] In another possible implementation, the user can input the attribute information of the clothes put into the washing machine through the laundry APP application on the mobile phone, or transmit the attribute information of the clothes that has been stored when the clothes were purchased to the washing machine from the smart home cloud platform.

[0091] After obtaining the attribute information, the controller will select the target material that meets the preset conditions from the materials corresponding to all the clothes.

[0092] Specifically, all the clothes put into the washing tub may be of the same material or similar materials. In this case, the target material can be set to the same material, or one material can be randomly selected from several similar materials as the target material, or the one with the largest number of similar materials can be selected from several similar materials as the target material.

[0093] Of course, it is understandable that the clothes put in may also be of different materials, and the materials may differ greatly. In this case, the most easily damaged material may be selected from all materials, such as silk, gauze fabric, etc. as the target material.

[0094] In a possible design, after obtaining the attribute information of the clothes, the relevant parameters of the washing program are reconfigured according to the attribute information, such as water intake, washing tub speed, water temperature, etc.; optionally, when the washing mode selected by the user conflicts with the material of the clothes, an alarm message can be issued, such as a warning screen on the washing machine panel, or a buzzer alarm sound or voice alarm sound, and an alarm prompt such as an alarm text message can be sent to the user's mobile terminal such as a mobile phone. If the user responds after a timeout, the washing mode corresponding to the material is used instead. If the user manually cancels the alarm, the washing is performed according to the mode selected by the user.

[0095] S202: Obtain current status information of the clothing.

[0096] In this step, the current status information includes: the current water weight of all clothes.

[0097] Specifically, after the washing program is completed and the water is drained, the weight sensor on the washing tub obtains the water weight of the clothes in the washing tub, that is, the total weight of the water content of the clothes currently in the washing tub.

[0098] Optionally, the distribution of the clothes in the laundry tub can also be collected by a camera device on the washing machine lid or inside the laundry tub to determine whether the clothes are in a loose state or a tangled state.

[0099] S203. Determine the water absorption characteristic parameter of the clothes according to the dry weight and the current water content weight.

[0100] In this step, the water absorption characteristic parameter is used to represent the water adsorption capacity of the overall water to be removed, and the overall water to be removed includes all the clothes. For example, cotton clothes have a stronger water adsorption capacity, while silk clothes or chemical fiber clothes have a weaker water adsorption capacity.

[0101] It should be noted that in this application, all the clothes are regarded as an overall water to be removed. Because the clothes may be entangled in the laundry tub due to flipping, at this time, dehydration and / or drying cannot correspond to the standard mode, thus generating a need to adjust relevant parameters. Such as increasing the number of forward and reverse rotations to untangle, or increasing the dehydration speed to enable the overall water to be removed to dehydrate better.

[0102] Specifically, one implementation manner of the water absorption characteristic parameter can be represented by the water content, that is, subtracting the dry weight of all the clothes in the laundry tub from the total water content weight of all the clothes to obtain the water content.

[0103] Another implementation manner of the water absorption characteristic parameter is the moisture content rate, that is, represented by the percentage of the water content in the dry weight.

[0104] In a possible design, the water content weight of the clothes can be detected multiple times, so that the change rate of the water content weight can be obtained and used to represent the water absorption characteristic of the overall water to be removed. When the change rate is large, the water absorption characteristic is small, and vice versa.

[0105] S204. Use a preset mapping model to determine the target control parameter according to the water absorption characteristic parameter.

[0106] In this step, the preset mapping model corresponds to the target material, and the target control parameter is used to control the running state of the next program, and the running state includes: on and off, the rotation speed of the laundry tub, temperature, drying power, etc.

[0107] Specifically, in this embodiment, the target control parameter includes: dehydration time and / or drying time. Then, first select the "water content - running time" mapping relationship curve corresponding to the target material in the database, that is, the preset mapping model, and find the dehydration time / drying time corresponding to the water content from the mapping relationship curve.

[0108] It can be understood that the target control parameters can also include the rotation speed of the washing tub, the drying power, the drying temperature, etc., and the corresponding parameter values can be obtained from the corresponding multiple mapping curves.

[0109] After obtaining the target control parameters, the washing machine is controlled according to the target control parameters so that the washing machine completes corresponding washing programs such as dehydration and / or drying programs.

[0110] It should be noted that steps S201 to S204 can be executed only once, or can be executed cyclically at a preset time interval, and continuously adjusted and corrected to better accurately control and adjust the relevant parameters of dehydration and / or drying when facing various different materials of clothes.

[0111] This embodiment provides a washing machine and its control method. By obtaining the attribute information of all the clothes in the washing tub, the attribute information includes the dry weight and material of the clothes, and screening out the target material that meets the preset conditions from all the materials; then obtaining the current state information of the clothes, including: the current water content weight of all the clothes; and then determining the water absorption characteristic parameters according to the dry weight and the current water content weight; finally, using a preset mapping model, according to the water absorption characteristic parameters, determining the target control parameters, and the target control parameters are used to control the state of the next program, and the state includes: on and off. It solves the technical problem that the control parameters of the washing machine in the prior art cannot be automatically adjusted according to the actual clothes washing situation, and achieves the technical effect of automatically adjusting the relevant parameters of dehydration or drying for clothes of different materials, different water contents, and different quantities, while saving energy and avoiding damage to clothes caused by excessive dehydration or drying, and improving the intelligent experience of users in using the washing machine.

[0112] Figure 3 It is a schematic flow chart of another washing machine control method provided by an embodiment of the present application. As Figure 3 shown, the specific steps of this washing machine control method include:

[0113] S301. Receive the identification information of the clothes sensed by the sensor.

[0114] In this step, the sensor includes: an image sensor, a wireless signal sensor, an infrared sensor, etc. The infrared sensor is used to obtain the number of clothes, and the identification information includes: the image of the clothes, the identification code, the RFID video identification data, etc.

[0115] Specifically, when the user puts the clothes into the washing machine, the camera device on the washing machine collects the image of the clothes, and then uses image recognition technology to distinguish the ID code of the clothes. Or the RFID electronic tag built in the clothes is read by the reader on the washing machine to obtain the identification information.

[0116] S302. Determine the attribute information of the clothing according to the preset database and the recognition information.

[0117] In this step, the controller can connect to the preset database in the Internet or the smart home Internet of Things, and obtain the attribute information of the clothing according to the recognition information such as the recognition code of the clothing. The attribute information includes: dry weight, material, clothing type, etc. That is, among the data stored in the preset database, the attribute information corresponding to the recognition information is filtered out.

[0118] In a possible case, if the attribute information corresponding to the recognition information is not pre-stored in the preset database, the preset estimated attribute is used as the attribute information, and the preset estimated attribute is used to represent the average comprehensive characteristics of multiple pieces of clothing.

[0119] Specifically, if the attribute information of the clothing placed in the washing machine by the user has not been collected in advance, the recognition code cannot be recognized in the clothing image collected by the imaging device, and naturally the corresponding attribute information cannot be searched in the database. However, when the clothing is detected to be placed in the washing tub by the infrared sensor, at this time, in order to achieve more accurate control, the estimated clothing closest to the clothing with unrecorded information can be identified through the image, and the attribute value of the estimated clothing, that is, the preset estimated attribute, is used as the attribute information of the clothing with unrecorded information.

[0120] It can be understood that if there is no imaging device in the washing machine, the weight obtained by the weight sensor in the washing tub can be used to select the attribute value of the clothing closest to its weight, that is, the preset estimated attribute value, as the attribute information of the clothing.

[0121] It can also be that in the preset database, a preset estimated attribute is stored in advance. This preset estimated attribute is the comprehensive evaluation attribute data obtained by developers through a large number of experiments, and is the attribute data obtained after the attribute information of various materials is simulated through a comprehensive algorithm.

[0122] S303. Screen out the target material that meets the preset conditions from the materials of all clothing attribute information.

[0123] In this step, the washing process of the washing machine can be divided into several step programs, such as: water injection program, washing program, drainage program, dehydration program, drying program, etc.

[0124] It should be noted that for the control method provided in this embodiment, the steps starting from this step are executed in a loop, and the loop steps can be embedded in each step program, and the relevant control parameters of each step program can be adjusted separately.

[0125] In the control method of this embodiment, before entering the next program, it is necessary to determine the control parameters of the next program:

[0126] If the next program is a washing program, screen out the material that has the greatest impact on washing control from all materials as the target material;

[0127] If the next program is a dehydration program, screen out the material that has the greatest impact on dehydration control from all materials as the target material;

[0128] If the next program is a drying program, screen out the material that has the greatest impact on drying control from all materials as the target material.

[0129] S304. Obtain the current status information of the clothes in a loop according to the preset detection conditions.

[0130] In this step, the current status information includes: the current water content weight of all clothes, the entanglement status of all the clothes in the current water to be removed, that is, in the washing tub, the temperature of the clothes or in the washing tub, the humidity in the washing tub, etc.

[0131] The preset detection conditions can be to perform loop detection according to a fixed time period, or to change the detection cycle time according to the change situation of the status information detected within a continuous preset number of times.

[0132] Specifically, if the change amount of the current water content weight within the preset loop times is greater than the first preset threshold, set the time change amount of the loop detection cycle to the first adjustment value;

[0133] Set a new loop detection cycle according to the first adjustment value and the current loop detection cycle.

[0134] For example, in the dehydration program, with 15 seconds as an original detection cycle, when the change rate of the water content weight detected continuously 2 times or continuously 3 times is greater than the preset threshold, such as greater than 3%, it is considered that the water absorption characteristic of the overall water to be removed is poor, and dehydration for 5 minutes can meet the drying requirement, and there is no need to perform the drying program anymore. At this time, the detection cycle can be extended to 30 seconds, that is, the time change amount of the detection cycle is 15S, and the new loop detection cycle is 30S. And after the next two detections, if it is found that the water content change rate changes according to 3%, the detection cycle remains unchanged, that is, the time change amount is 0; if it is found that the water content change rate is less than 3%, set the time change rate to -15S, that is, adjust the loop detection cycle back to 15S again.

[0135] Similarly, in another possible design, if the change amount of the current water content weight within the preset loop times is less than the second preset threshold, set the time change amount to the second adjustment value;

[0136] Set a new cycle detection period according to the second adjustment value and the current cycle detection period.

[0137] In another possible design, if the change amount of the current water content weight within the preset number of cycles is greater than or equal to the second preset threshold and less than or equal to the first preset threshold, then set the time change amount to a third adjustment value;

[0138] Set a new cycle detection period according to the third adjustment value and the current cycle detection period.

[0139] In this way, by continuously adjusting the cycle detection period in different laundry step programs, such as the dehydration program or the drying program, it is possible to dynamically and more accurately adjust the relevant control parameters. It can not only achieve accurate and rapid response to the state changes of the overall water to be removed, but also take into account the flexible allocation of the controller's computing resources, thereby saving energy consumption.

[0140] S305. Re-determine the water absorption characteristic parameters of the clothes according to the dry weight and the current water content weight in the current state information.

[0141] In this step, the water absorption characteristic parameters are used to represent the water adsorption capacity of the overall water to be removed, and the overall water to be removed includes all the clothes.

[0142] The water absorption characteristic parameters include: water content, water content percentage, change amount of water content, average water content change rate, etc. It should be noted that those skilled in the art can select the implementation form of the water absorption characteristic parameters according to actual needs, and this application does not make any limitations.
