Description

Technical Field

[0002] Dehydration of washing equipment refers to the use of centrifugal force to separate the water from the clothes in the washing machine, and the dehydration speed will directly affect the dehydration effect of the washing machine.

[0051] In order to more clearly illustrate the technical solution of the present application, the following is a brief introduction to the drawings required for use in the embodiments. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0052] Figure 1 This is a flow chart of the dehydration control method for washing equipment provided in an embodiment of the present application.

[0053] Figure 2 This is a schematic diagram of the structure of the washing equipment provided in an embodiment of the present application. DETAILED DESCRIPTION

[0054] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0055] Dehydration of washing equipment refers to the use of centrifugal force to separate the water from the clothes in the washing machine, and the dehydration speed will directly affect the dehydration effect of the washing machine.

[0056] When a user uses a washing machine to spin clothes, they can intuitively understand the performance of the washing machine through the washing and spinning results. Regarding the spin effect, if the spin time is long and energy consumption increases, or if the spin speed does not reach the set value after the spin is completed, resulting in a high moisture content in the clothes, the user experience will be poor.

[0057] Therefore, this problem can be solved by using an optimized correction strategy to control the preset dehydration curve, achieving rapid dehydration while meeting dehydration and drying requirements. Alternatively, dynamic eccentricity detection can be implemented to detect eccentricity at high speeds and control the actual preset dehydration curve. These solutions typically assign specific time and speed requirements to the curve. Depending on the load, the time may be too long or too short, or the speed may be too high or too low, making it impossible to perfectly match energy consumption and performance.

[0058] To solve the problem of mismatch between energy consumption and performance of washing equipment under different load conditions, refer to Figure 1 , an embodiment of the present application provides a dehydration control method for a washing device, comprising:

[0059] S100: receiving a dehydration start instruction to obtain dehydration parameters.

[0060] Among them, the dehydration parameters include dehydration time, preset dehydration curve, preset drum speed and drying setting; the horizontal axis of the preset dehydration curve is time, and the vertical axis is speed.

[0061] Specifically, among the dehydration parameters, the dehydration time is the maximum operating time of the washing equipment. The controller in the washing equipment can detect the time of the dehydration process. When the dehydration time is greater than the pre-set dehydration time, the washing equipment can be directly shut down to reduce energy consumption.

[0062] The preset spin curve is a pre-set curve showing the speed change over time. This means that after the washing machine begins spinning, the drum speed changes over time according to the preset spin curve, adjusting to the speed corresponding to that point in time. For example, at 50 seconds, the preset spin curve corresponds to a speed of 2000 rpm, while at 60 seconds, it corresponds to a speed of 2100 rpm. By setting a preset spin curve, the performance of the washing machine can be aligned with its energy consumption, reducing energy consumption and noise caused by high-speed vibration.

[0063] The preset drum speed is when the washing machine starts to dehydrate, and the clothes in the drum enter the leveling pre-dehydration stage as the drum rotates. At this time, the drum speed reaches the preset drum speed.

[0064] The drying setting is to determine whether to dry the clothes after dehydration. It can be set according to user habits or dehydration of clothes.

[0065] In addition, the specific steps of receiving the dehydration start instruction and obtaining the dehydration parameters include:

[0066] Generate an instruction for obtaining dehydration parameters to control the wireless device to send the instruction for obtaining dehydration parameters to the server.

[0067] According to the instruction to obtain the dehydration parameters, the control server sends the dehydration parameters to the washing device.

[0068] Specifically, when a user presses the spin button, the controller responds to the user's spin command and controls the wireless device to request spin parameters from the server. For example, in a washing machine, a dedicated spin parameter acquisition instruction can be generated based on pre-set logic and the current machine status. This spin parameter acquisition instruction includes the requested spin duration, pre-set spin curve, pre-set drum speed, and drying settings, ensuring that the server can accurately understand and respond to the request.

[0069] The wireless device then formats the generated command according to the pre-defined communication protocol format. The formatted dehydration parameter acquisition command is temporarily stored in the wireless device's transmit buffer, ready for subsequent transmission. At the same time, relevant transmission parameters, such as the target server address and port number, are set.

[0070] Once the wireless device successfully establishes a connection with the server, it retrieves the dehydration parameter acquisition instruction from its transmit buffer and sends it to the server via the wireless communication link. During this transmission process, data fragmentation and encapsulation may be necessary to accommodate wireless transmission requirements. A timer can also be started to monitor the command transmission status and timeouts. The device then waits for the server to return an acknowledgment confirming successful receipt of the dehydration parameter acquisition instruction. If no acknowledgment is received within the specified time, or if an error message is received, the wireless device will retransmit the instruction or implement appropriate error handling measures.

[0071] When the server receives a command to obtain dehydration parameters from a wireless device, it first performs an integrity check and validation on the data. For example, it verifies the data's checksum field and the command format to ensure the command's legitimacy and accuracy. It then parses the command content to extract key information, such as the device identifier and the requested dehydration parameter type.

[0072] After the server obtains the device identifier, it searches the database or configuration file for the dehydration parameters of the corresponding washing machine. The dehydration parameters may be default values ​​pre-stored on the server, personalized parameters set by the user through other means, or dehydration parameters updated by the user after multiple uses.

[0073] S200: Control the motor to start so that the drum speed reaches a preset drum speed.

[0074] When the washing machine starts to dehydrate, the motor starts, which drives the drum to rotate. Then, by continuously adjusting the input voltage and frequency, the motor speed is increased, so that the clothes in the drum enter the flattening and dehydration stage. The motor drives the drum to rotate at a stable speed, using centrifugal force to throw out the water in the clothes, ensuring the dehydration effect and safety.

[0075] S300: According to the preset dehydration curve, in a chronological order, the drum speed is controlled to run at the speed of the preset dehydration curve;

[0076] The preset dehydration curve is a curve that plots the speed over time. That is, the horizontal axis of the preset dehydration curve is time, and the vertical axis is the drum speed corresponding to that time. When the drum speed reaches the preset drum speed, the drum speed will be adjusted according to the preset dehydration curve. For example, if the preset drum speed is 3000 r / min, the drum speed corresponding to 0-60s is 3000 r / min, and the drum speed corresponding to 60-120s is 2800 r / min, then when the drum speed reaches the preset drum speed, the drum speed will be 3000 r / min for the first minute and 2800 r / min for the second minute.

[0077] S400: Obtain the imbalance value and weighing value of the washing equipment.

[0078] When the drum speed runs at the preset dehydration curve, the imbalance value and weighing value of the washing equipment under the high-speed rotation of the drum can also be monitored in real time, and the drum speed can be adjusted according to the imbalance value and weighing value.

[0079] The specific steps of obtaining the imbalance value and weighing value of the washing equipment include:

[0080] Get the current change when the motor speed remains unchanged.

[0081] Calculate the unsmoothed value based on the current change.

[0082] Get the power consumption of the motor when the speed changes.

[0083] Calculate the weighing value based on the power consumption.

[0084] Specifically, the unbalance value is calculated based on the change in motor current when the drum speed is stable. The larger the unbalance value, the larger the change in motor current.

[0085] The weighing value can be calculated based on the amount of electricity consumed by the motor during acceleration. Different weighing values ​​will result in different electricity consumption at the same drum speed.

[0086] When the drum speed is stable, the magnitude of the change in the motor's current is related to the uneven distribution of the clothes in the drum. If the clothes are unevenly distributed, it will cause centrifugal force imbalance during the rotation of the drum, causing the motor current to change. The greater the current change, the more uneven the clothes are distributed, that is, the greater the imbalance value. Therefore, the imbalance value is calculated by measuring the current values ​​of the motor when it is unloaded and loaded, and obtaining the current change ΔI = Iload - Inoload. Then, according to the motor's characteristic curve or empirical formula, the current change is converted into an imbalance value. For example, a corresponding relationship table between the motor current change and the imbalance value is obtained through experiments, and the corresponding imbalance value is found in the table based on the measured current change.

[0087] During the weight calculation process, the motor needs to overcome resistance such as the inertia and friction of the clothing inside the drum during acceleration, and the amount of electrical energy consumed is related to the weight of the clothing. The greater the weight, the more electrical energy required, and the greater the current consumption. Therefore, the weight can be calculated based on the current consumption of the motor during acceleration. For example, the current value Iacceleration and the acceleration time tacceleration are measured during the acceleration process. Based on the electrical energy formula W = UIt, and with the voltage U set constant, the electrical energy W consumed by the motor during acceleration is calculated. Then, based on the motor's efficiency η, which can be determined from the motor's specifications, the actual energy output of the motor, E = W × η, is calculated. Furthermore, based on the relationship between energy and weight, for example, the energy e required per unit weight of clothing during acceleration, determined experimentally, the weight G can be calculated using the formula G = E / e.

[0088] S500: comparing the imbalance value with a preset imbalance value range to adjust a preset dehydration curve according to the comparison result;

[0089] Comparing the imbalance value with the preset dehydration curve to adjust the preset dehydration curve according to the comparison result specifically includes:

[0090] If the unbalance value is greater than the maximum value of the preset unbalance value range, the speed in the preset dehydration curve is controlled to decrease;

[0091] If the unbalance value is less than the minimum value of the preset unbalance value range, the rotation speed in the preset dehydration curve is controlled to increase.

[0092] Specifically, when the drum speed reaches the preset drum speed, the controller of the washing equipment will detect the current change of the motor in real time and send the current change to the server through a wireless device. The server calculates the imbalance value based on the current change. When the imbalance value is greater than the maximum value of the preset imbalance value range, it means that the drum speed is too high. The speed in the preset dehydration curve can be controlled to decrease. When the speed in the preset dehydration curve decreases, the controller can control the drum speed to decrease after receiving the preset dehydration curve sent by the server. When the imbalance value is less than the minimum value of the preset imbalance value range, the drum speed is too low and the dehydration effect is reduced. The speed in the preset dehydration curve can be controlled to increase. When the speed in the preset dehydration curve increases, the controller can control the drum speed to increase after receiving the preset dehydration curve sent by the server.

[0093] S600: Calculate the change in the weighing value within the preset interval time.

[0094] S700: If the change is within a preset range, a stop dehydration instruction is generated to control the washing device to stop.

[0095] When the imbalance value remains within a preset range for a certain period of time, the system can determine whether dehydration can be stopped by monitoring the weighing value. For example, if the imbalance value changes within a certain range for more than 30 seconds, the system will start monitoring the real-time weighing value. If the change in the weighing value within the preset range within the preset interval, dehydration can be stopped early, effectively reducing energy consumption.

[0096] In some embodiments, the washing equipment dehydration control method further includes:

[0097] Get the running time of the motor.

[0098] If the running time is greater than the preset running time, a stop dehydration instruction is generated to control the washing equipment to stop.

[0099] Specifically, when the change in the weighing value has not been within the preset range, and the preset running time can be obtained based on the dehydration time in the dehydration chamber, when the running time of the motor is greater than the preset running time, the controller can generate a stop dehydration instruction, control the motor to stop, and stop the dehydration operation to prevent the clothes from being dehydrated for too long and wasting energy.

[0100] In some embodiments, after generating a dehydration stop instruction to control the washing device to stop, the dehydration control method for the washing device further includes:

[0101] Get drying settings;

[0102] If the drying mode is set to drying, the washing machine is controlled to start the drying mode.

[0103] Specifically, after the clothes are dehydrated, the drying setting in the dehydration parameters can also be obtained. For example, when the drying setting is set to dry, the washing machine can start the drying function to dry the clothes. When the drying setting is set to non-drying, the washing machine stops and opens the washing machine to facilitate the user to take the clothes out of the washing machine.

[0104] In some embodiments, after generating a dehydration stop instruction to control the washing device to stop, the dehydration control method for the washing device further includes:

[0105] Obtain the real-time speed of the drum and generate an actual dehydration curve based on the real-time speed;

[0106] Compare the actual dehydration curve with the preset dehydration curve;

[0107] If the actual dehydration curve is different from the preset dehydration curve, the preset dehydration curve is replaced by the actual dehydration curve.

[0108] Specifically, the drum speed changes based on a preset dehydration curve. When the speed in the preset dehydration curve is adjusted, the drum speed also adjusts accordingly. Therefore, after the dehydration process is complete, the server will also plot an actual dehydration curve based on the real-time drum speed during the dehydration process, showing the drum speed changing over time. If the actual dehydration curve matches the preset dehydration curve, there's no need to update the preset dehydration curve. If the actual dehydration curve differs from the preset dehydration curve, the preset dehydration curve is replaced with the actual one. By updating the preset dehydration curve, the dehydration performance of the washing machine can be improved.

[0109] In some embodiments, the present application provides a washing device, which is applied to the dehydration control method of the washing device provided in the above embodiments. The washing device includes: a controller, a drum, and a motor.

[0110] The motor is used to drive the drum to rotate.

[0114] Control the motor to start so that the drum speed reaches the preset drum speed.

[0115] According to the preset dehydration curve, the drum speed is controlled to run at the speed of the preset dehydration curve in chronological order.

[0116] Obtain the unbalance value and weighing value of the washing equipment.

[0117] The imbalance value is compared with a preset imbalance value range to adjust the preset dehydration curve according to the comparison result.

[0118] Calculate the change in the weighing value within the preset interval.

[0119] If the change is within a preset range, a stop dehydration instruction is generated to control the washing equipment to stop.

[0120] In some embodiments, the washing device further comprises a wireless device and a server; the server is connected to the controller via a wireless module;

[0121] The controller is configured as:

[0122] Generate an instruction for obtaining dehydration parameters to control the wireless device to send the instruction for obtaining dehydration parameters to the server.

[0123] According to the instruction to obtain the dehydration parameters, the control server sends the dehydration parameters to the washing device.

[0124] It can be seen from the above technical solution that the present application provides a dehydration control method for a washing device and a washing device. The dehydration control method for the washing device includes receiving a start dehydration instruction to obtain dehydration parameters; the dehydration parameters include dehydration time, a preset dehydration curve, a preset drum speed and a drying setting; the horizontal axis of the preset dehydration curve is time, and the vertical axis is the speed; controlling the motor to start so that the drum speed reaches the preset drum speed; according to the preset dehydration curve, in a time sequence, controlling the drum speed to run at the speed of the preset dehydration curve; obtaining the imbalance value and weighing value of the washing device; comparing the imbalance value with the preset imbalance value range to adjust the preset dehydration curve according to the comparison result; calculating the change in the weighing value within the preset interval time; if the change is within the preset range, generating a stop dehydration instruction to control the washing device to stop. By acquiring real-time imbalance and weight values, the washing machine's speed is corrected.
