Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a dehydration control method, device, clothing processing equipment and storage medium. Background Technology

[0002] With the rapid development of smart technology, users increasingly expect various home appliances (such as garment processing equipment) to become more and more intelligent. Existing garment processing equipment uses a fixed distribution time set by the factory default, which can cause the following problems: 1. If the distribution time is insufficient, the clothes will be unevenly distributed, and the inner drum will not reach a high speed during the subsequent spin-drying process, affecting the final dehydration effect; 2. If the distribution time is too long, the spin-drying time will be too long, damaging the clothes and wasting time and energy. Therefore, the required distribution time will vary depending on the dehydration environment, and a fixed distribution time may not be optimal, affecting the dehydration effect or damaging the clothes, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a dehydration control method, apparatus, garment processing equipment, and storage medium, which can ensure the accuracy of the distribution time setting, quickly and efficiently achieve the expected garment distribution effect, solve the problems of poor garment dehydration effect caused by insufficient distribution time and damage to garments caused by excessive distribution time in the prior art, optimize garment distribution effect and garment dehydration effect, and improve the user experience of using garment processing equipment.

[0004] In a first aspect, this application provides a dehydration control method applied to clothing processing equipment, the method comprising:

[0005] When the execution of the dehydration process is detected, the current distance between the inner and outer drums in the garment processing equipment is obtained;

[0006] Determine the initial distribution time for uniformly distributing the clothes in the inner tub during the dehydration process;

[0007] If the absolute value of the difference between the current distance and the stable distance is greater than the preset distance value, the initial distribution time is adjusted to obtain the target distribution time, and the dehydration procedure is executed based on the target distribution time.

[0008] This application provides a dehydration control method. By adding a distance sensor to the structure of a traditional garment processing device, the method detects the current distance between the inner and outer drums during load dehydration, thus obtaining the distribution of clothes in the inner drum. This distance is compared with a stable distance to determine whether the initial distribution time needs adjustment. When adjustment is needed, the real-time distribution time is determined based on the current dehydration environment of the garment processing device, and the initial distribution time is adjusted based on the real-time distribution time to obtain the target distribution time. This application determines the real-time distribution time by acquiring the dehydration environment of the inner drum of the garment processing device and continuously adjusts the initial distribution time. This method ensures the accuracy of the distribution time setting, quickly and efficiently achieving the desired garment distribution effect. It solves the problems of poor dehydration effect caused by insufficient distribution time and damage to clothes caused by excessive distribution time in existing technologies. It optimizes the garment distribution and dehydration effects, improving the user experience of the garment processing device.

[0009] Furthermore, the garment processing device is equipped with a distance sensor, which is disposed on the inner wall of the outer tub; obtaining the current distance between the inner tub and the outer tub in the garment processing device includes: detecting a first set of distances between the inner tub and the outer tub through the distance sensor within the current task cycle; and taking the smallest first distance in the first set of distances as the current distance.

[0010] Furthermore, adjusting the initial distribution time to obtain the target distribution time includes: determining the real-time distribution time for the clothes in the inner tub to be evenly distributed; determining the time error between the initial distribution time and the real-time distribution time; when the time error exceeds a preset range, assigning the value of the real-time distribution time to the initial distribution time to obtain an intermediate distribution time; repeating the operation of determining the real-time distribution time for the clothes in the inner tub to be evenly distributed in the next task cycle until the time error does not exceed the preset range, and then using the intermediate distribution time as the target distribution time.

[0011] Furthermore, determining the real-time distribution time for uniform distribution of clothing in the inner tub includes: determining the distance error corresponding to the first distance set; determining the current motor speed of the clothing processing device based on the distance error; and calculating the real-time distribution time based on the weight and material of the clothing in the inner tub and the current motor speed.

[0012] Furthermore, the garment handling device is equipped with a garment weight sensor, which determines the weight of the garments in the following manner: when a washing program is detected, the water inlet assembly is controlled to introduce a preset amount of water into the inner tub; the motor is controlled to be powered on and rotate for a first preset time, and then the motor is controlled to be powered off; when the motor rotates due to inertia, the first pulse value of the pulse signal of the induced electromotive force generated by the garment weight sensor is determined; the weight of the garments is determined based on the first pulse value.

[0013] Furthermore, the garment processing equipment is equipped with a garment material sensor, which determines the garment material as follows: After controlling the motor to be powered on and rotating at a preset temperature for a second preset time, the motor is then powered off; while the motor rotates due to inertia, the second pulse value of the pulse signal of the induced electromotive force generated by the garment material sensor is determined; the operation of controlling the motor to be powered on and rotating at a preset temperature for a second preset time and then powered off is repeated a preset number of times to obtain a preset set of second pulse values; the average of the second pulse value set is calculated to obtain a new second pulse value; the pulse difference between the new second pulse value and the first pulse value is determined; the fabric impedance of the garment in the inner tub is determined based on the pulse difference, and the garment material is determined based on the fabric impedance.

[0014] Furthermore, the stable distance is determined as follows: when the garment processing equipment is in an unloaded state, the motor is controlled to rotate for a third preset time; while the motor drives the inner tub to rotate, the unloaded distance between the inner tub and the outer tub is determined; a preset percentage of the unloaded distance is taken as the stable distance, which is the distance between the inner tub and the outer tub when the garment processing equipment is under load dehydration and the inner tub remains in a stable state.

[0015] Secondly, this application provides a dehydration control device integrated into a garment processing device, the device comprising:

[0016] The distance determination module is used to obtain the current distance between the inner drum and the outer drum in the clothing processing equipment when the execution of the dehydration program is detected.

[0017] A time determination module is used to determine the initial distribution time for uniformly distributing the clothes in the inner tub during the dehydration process;

[0018] The dehydration control module is used to adjust the initial distribution time to obtain the target distribution time if the absolute value of the difference between the current distance and the stable distance is greater than the preset distance value, and then execute the dehydration program based on the target distribution time.

[0019] Thirdly, this application provides a garment processing device, which includes:

[0020] At least one processor; and

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0034] It should be noted that the terms "first," "second," "target," and "original," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0035] Figure 1 This is a first flowchart illustrating a dehydration control method provided in this application embodiment. This embodiment is applicable to adjusting the distribution time of clothes for uniform distribution based on the dehydration environment conditions during the dehydration process of a garment processing device, thereby improving the dehydration effect of the garment processing device. The dehydration control method provided in this embodiment can be executed by the dehydration control device provided in this application embodiment. This device can be implemented through software and / or hardware and integrated into the electronic device executing the method. Preferably, the electronic device in this application embodiment can be a garment processing device, such as a washing machine.

[0036] See Figure 1The method in this embodiment includes, but is not limited to, the following steps:

[0037] S110. When the execution of the dehydration program is detected, obtain the current distance between the inner drum and the outer drum in the garment processing equipment.

[0038] The garment handling equipment is used to wash and care for clothes. It may include washing and care programs and a spin-drying program, with the spin-drying program executed by a motor. Optionally, the garment handling equipment is equipped with a distance sensor, which can be mounted on the inner wall of the outer tub or on the outer wall of the inner tub. When mounted on the outer wall of the inner tub, a receiving device can be mounted on the inner wall of the outer tub to receive the distance signal from the distance sensor. During the rotation of the inner tub, when the distance sensor and the receiving device meet, the distance between the inner and outer tubs can be determined.

[0039] In this embodiment, a computer processor can be introduced into the garment processing equipment. Using a computer processor enables the garment processing equipment to have more powerful data processing and control programming capabilities. The computer processor of the garment processing equipment obtains the currently executing program. When it detects that the executing program is a dehydration program, it obtains the current distance between the inner and outer tubs in the garment processing equipment. Further, this includes setting a task cycle at preset intervals (e.g., one minute). The garment processing equipment uses a distance sensor to detect the first distance between the inner and outer tubs at the measurement point (the location where the distance sensor is installed) in real time. Multiple first distances can be obtained within the current task cycle as the inner tub rotates, thus obtaining a set of first distances. The smallest first distance is selected from the set of first distances and used as the current distance.

[0040] S120. Determine the initial distribution time for uniformly distributing the clothes in the inner drum during the spin-drying process.

[0041] In this embodiment of the application, when the clothing processing device performs the operation of uniformly distributing the clothes in the inner drum, it may use the fixed distribution time set by default at the factory as the initial distribution time, or it may calculate the current distribution time corresponding to the first task cycle and use the current distribution time as the initial distribution time.

[0042] The calculation process for the current distribution time can be as follows: Within the first task cycle, detect the weight and material of the clothing, then detect the motor speed at that time, and finally calculate the current distribution time based on the clothing weight, material, and motor speed. The specific process for calculating the current distribution time based on clothing weight, material, and motor speed will be explained below. Figure 2 The corresponding embodiments are explained in detail.

[0043] Optionally, the dehydration program of the garment processing equipment may include two stages: a low-speed distribution stage and a high-speed dehydration stage. The low-speed distribution stage can be set to a default distribution speed of 30 r / min.

[0044] S130. If the absolute value of the difference between the current distance and the stable distance is greater than the preset distance value, the initial distribution time is adjusted to obtain the target distribution time, and the dehydration procedure is executed based on the target distribution time.

[0045] In this embodiment, under load, if the clothes in the inner tub are unevenly distributed, the measurement point can be on the side with more clothes or the side with fewer clothes. When it's the side with more clothes, the current distance is less than the stable distance; when it's the side with fewer clothes, the current distance is greater than the stable distance. Regardless of the clothing distribution, the absolute value of the difference between the current distance and the stable distance is first calculated and then compared with a preset distance value. If the absolute value of the difference between the current distance and the stable distance is less than or equal to the preset distance value, it indicates that the clothes in the inner tub are evenly distributed, and there is no need to shake the clothes or adjust the initial distribution time. If the absolute value of the difference between the current distance and the stable distance is greater than the preset distance value, it indicates that the clothes in the inner tub are unevenly distributed, and it is necessary to shake the clothes and adjust the initial distribution time to obtain the target distribution time. Finally, the motor is controlled to execute the spin-drying program based on the target distribution time.

[0046] The process of adjusting the initial distribution time can be as follows: determine the current dehydration environment status of the garment processing equipment, determine the real-time distribution time based on the dehydration environment status, and then adjust the initial distribution time based on the real-time distribution time to obtain the target distribution time. The dehydration environment status may include, but is not limited to, at least one of the following: temperature, water volume, garment weight, and garment material.

[0047] Optionally, if both the inner and outer tubs are cylindrical, the distances between corresponding points on the inner tub and the outer tub are equal when unloaded. Under load, if the clothes in the inner tub are unevenly distributed, and the current distance is not the shortest distance between the inner and outer tubs, the shortest distance can be calculated based on the measured current distance.

[0048] Furthermore, the stable distance is determined as follows: when the garment processing equipment is in an unloaded state, the motor is controlled to rotate for a third preset time (e.g., half a minute); while the motor drives the inner tub to rotate, the unloaded distance between the inner tub and the outer tub is determined; a preset percentage of the unloaded distance (e.g., 20%) is taken as the stable distance. The stable distance is the distance between the inner tub and the outer tub when the garment processing equipment is under load for dehydration and the inner tub remains in a stable state.

[0049] The technical solution provided in this embodiment obtains the current distance between the inner and outer drums of the garment processing equipment when a dehydration process is detected; determines the initial distribution time for uniformly distributing the clothes in the inner drum during the dehydration process; if the absolute value of the difference between the current distance and the stable distance is greater than a preset distance value, the initial distribution time is adjusted to obtain the target distribution time, and the dehydration process is executed based on the target distribution time. This application adds a distance sensor to the structure of a traditional garment processing equipment. The distance sensor detects the current distance between the inner and outer drums of the garment processing equipment during load dehydration, thereby obtaining the distribution of clothes in the inner drum. This is compared with the stable distance to determine whether to adjust the initial distribution time; when adjustment is needed, the real-time distribution time is determined based on the current dehydration environment of the garment processing equipment, and the initial distribution time is adjusted based on the real-time distribution time to obtain the target distribution time. This application determines the real-time distribution time by obtaining the dehydration environment status of the inner drum of the clothing processing equipment and continuously adjusts the initial distribution time. In this way, the accuracy of the distribution time setting can be guaranteed, and the expected clothing distribution effect can be achieved quickly and efficiently. This can solve the problems of poor clothing dehydration effect caused by insufficient distribution time and clothing damage caused by excessive distribution time in the prior art. It can optimize the clothing distribution effect and clothing dehydration effect, and improve the user experience of using clothing processing equipment.

[0050] The dehydration control method provided in the embodiments of this application is further described below. Figure 2 This is a schematic diagram of the second process of a dehydration control method provided in an embodiment of this application. This embodiment is an optimization based on the above embodiment, specifically an optimization whereby the process of adjusting the initial distribution time to obtain the target distribution time is explained in detail.

[0051] See Figure 2 The method in this embodiment includes, but is not limited to, the following steps:

[0052] S210. Determine the distance error corresponding to the first distance set.

[0053] This step can be: In Figure 1 In step S110 of the corresponding embodiment, when a dehydration program is detected, the garment processing equipment uses a distance sensor to detect in real time the first distance between the inner tub and the outer tub at the point to be measured (the location where the distance sensor is installed). Multiple first distances can be obtained as the inner tub rotates within the current task cycle, thus obtaining a first distance set. Then, data analysis is performed on the first distances in the first distance set, and the distance error is calculated according to a preset error formula.

[0054] This step can also be: select the first distance between the inner and outer buckets at two consecutive times within a preset time (e.g., one minute) from the first distance set, and calculate the distance error by performing error calculation on these two first distances according to the preset error formula.

[0055] S220. Determine the current motor speed of the clothing processing equipment based on the distance error.

[0056] In this embodiment, a proportional-integral-derivative (PID) control algorithm can also be introduced into the clothing processing equipment. Using the PID control algorithm allows the clothing processing equipment to adjust the distribution time more accurately. The distance error obtained in step S210 can be input into the PID control algorithm, and the output based on the PID control algorithm can obtain the current motor speed of the clothing processing equipment.

[0057] S230: Calculate the real-time distribution time based on the weight of the clothes in the inner tub, the material of the clothes, and the current motor speed.

[0058] In this embodiment, the dehydration environment state may include the weight and material of the clothes in the inner tub. The required distribution time varies depending on the weight and material of the clothes in the inner tub. Therefore, it is necessary to first determine the current dehydration environment state, and then calculate the real-time distribution time based on the current motor speed. The real-time distribution time can be represented by the following formula (1):

[0059] F(x)=a1*f1(x)+a2*f2(x)+a3*f3(x) (1)

[0060] In the formula, F(x) represents the real-time distribution time required to evenly distribute the clothes in the inner tub; f1(x) represents the functional relationship between the weight of the clothes and the distribution time, and a1 is the distribution weight coefficient corresponding to the weight of the clothes; f2(x) represents the functional relationship between the material of the clothes and the distribution time, and a2 is the distribution weight coefficient corresponding to the material of the clothes; f3(x) represents the functional relationship between the current motor speed and the distribution time, and a3 is the distribution weight coefficient corresponding to the current motor speed.

[0061] Furthermore, the garment handling equipment is equipped with a garment weight sensor to determine the weight of the garments as follows: When the user puts the garments into the inner tub of the garment handling equipment, the garment handling equipment is turned on when the user triggers the physical or virtual start button on the garment handling equipment; when the washing program is detected to be running, the garment weighing function is first activated, specifically by: controlling the water inlet component to add a preset amount of water to the inner tub; controlling the motor to be powered on and running for a first preset time (e.g., one minute), and then controlling the motor to be powered off; when the motor rotates due to inertia, the first pulse value of the pulse signal of the induced electromotive force generated by the garment weight sensor is determined; the weight of the garments is determined based on the first pulse value.

[0062] Furthermore, the garment processing equipment is equipped with a garment material sensor, which determines the garment material as follows: The water inlet assembly is controlled to supply a preset amount of water to the inner drum; the motor is powered on and rotated at a preset temperature (e.g., 30°C) for a second preset time (e.g., half a minute), then powered off; while the motor rotates due to inertia, the second pulse value of the induced electromotive force pulse signal generated by the garment material sensor is determined; the operation of powering on the motor, rotating it at the preset temperature for a second preset time, and then powering it off is repeated a preset number of times (e.g., three times), obtaining a preset set of second pulse values ​​corresponding to the preset number of times; the average of the second pulse value set is calculated to obtain a new second pulse value; the pulse difference between the new second pulse value and the first pulse value is determined; the fabric impedance of the garment in the inner drum is determined based on the pulse difference, and the garment material is determined based on the fabric impedance. In other words, the garment material can be determined by subtracting the number of pulses obtained when measuring garment quantity from the number of pulses obtained when measuring garment material. If the proportion of cotton fibers in the clothes in the drum is large, the pulse number difference will be large; if the proportion of chemical fibers is large, the pulse number difference will be small.

[0063] Generally, the weight and fabric composition of clothes are measured before washing. Fabric composition primarily determines whether the clothes are cotton or synthetic fibers. Different fabrics have different compositions and therefore different fabric impedances under a given water level. To determine the fabric composition, a certain amount of water is added and the motor is run at a preset temperature. Then, the power is suddenly cut off. Due to inertia, the motor will continue to rotate for a short time. At this time, the motor is in generator mode, generating a certain induced electromotive force that gradually decays to zero. Since the decay rate has a linear relationship with fabric impedance, the electrical heating at both ends of the stator winding is rectified and detected, and then photoelectrically isolated to form a pulse signal. The more pulse signals, the lower the fabric impedance, and vice versa. After several measurements, the fabric impedance can be determined, and the fabric composition can be deduced from this. Optionally, the fabric weight sensor can be a resistance sensor. The fabric weight sensor and the fabric quantity sensor can be the same device, only the detection method differs, i.e., the motor's operating state differs.

[0064] S240. Determine the time error between the initial distribution time and the real-time distribution time.

[0065] In this embodiment, when the clothing processing device performs a uniform distribution operation on the clothes in the inner drum, it can use the fixed distribution time set by the factory default as the initial distribution time, or it can calculate the current distribution time corresponding to the first task cycle and use the current distribution time as the initial distribution time. Then, after calculating the real-time distribution time based on the weight of the clothes in the inner drum, the material of the clothes, and the current motor speed in step S230, the time error between the initial distribution time and the real-time distribution time is calculated.

[0066] S250. When the time error exceeds the preset range, the value of the real-time distribution time is assigned to the initial distribution time to obtain the intermediate distribution time.

[0067] In this embodiment, the preset range can be set by the user according to actual needs, or it can be a fixed value set by the garment processing equipment before leaving the factory. When the time error exceeds the preset range, it indicates that the initial distribution time is not set appropriately or accurately. In this case, the initial distribution time needs to be updated by assigning the value of the real-time distribution time to the initial distribution time to obtain the intermediate distribution time.

[0068] S260. Repeat the operation of determining the real-time distribution time for uniform distribution of clothes in the inner tub in the next task cycle until the time error does not exceed the preset range, and take the intermediate distribution time as the target distribution time.

[0069] In this embodiment of the application, the operation of determining the real-time distribution time for uniform distribution of clothes in the inner tub is repeated in the next task cycle. That is, the operation of determining the distance error corresponding to the first distance set is repeated in the next task cycle until the time error does not exceed the preset range. Then, the intermediate distribution time of this task cycle is stopped from being updated, and the intermediate distribution time obtained in this task cycle is taken as the target distribution time.

[0070] The technical solution provided in this embodiment involves determining the distance error corresponding to a first distance set; determining the current motor speed of the clothing processing equipment based on the distance error; calculating the real-time distribution time based on the weight and material of the clothing in the inner tub and the current motor speed; determining the time error between the initial distribution time and the real-time distribution time; when the time error exceeds a preset range, assigning the value of the real-time distribution time to the initial distribution time to obtain an intermediate distribution time; and repeating the operation of determining the real-time distribution time for uniform distribution of clothing in the inner tub in the next task cycle until the time error does not exceed the preset range, at which point the intermediate distribution time is taken as the target distribution time. This application adds a PID control algorithm to the structure of traditional garment processing equipment. The PID control algorithm provides feedback adjustment to the dehydration process. Specifically, it controls the time error within a reasonable range by providing feedback on the error between the initial distribution time and the real-time distribution time calculated per unit time during garment distribution. Furthermore, it determines the real-time distribution time by acquiring the dehydration environment status of the inner drum of the garment processing equipment and continuously adjusts the initial distribution time, thereby ensuring the accuracy of the distribution time setting. This allows for rapid and efficient achievement of the desired garment distribution effect, solving the problems of poor dehydration due to insufficient distribution time and damage to garments due to excessive distribution time in existing technologies. It optimizes both garment distribution and dehydration effects, improving the user experience of the garment processing equipment.
