Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances. Specifically, it particularly relates to a drying control method for a washing machine. Background Art

[0002] With the improvement of people's living standards, the demand for the drying function in washing machines has increased. Currently, the drying effect of washing machines with drying function is not good. The main problems are long drying time, incomplete drying, high energy consumption, etc. The reason for incomplete drying is that the diameter of the drum is relatively small, and the clothes cannot be fully shaken out, resulting in the clothes being knotted and curled, and the innermost part being wet.

[0003] In the prior art, a humidity detection device that detects the humidity of clothes in contact and is connected to the controller of the drying device is provided in the drying drum of the drying device. During the drying process, the humidity frequency of the humidity signal is selected, or at least one of the humidity amplitude and the temperature in the drying drum is used while using the humidity frequency as the basis for judging whether the clothes are entangled. When entanglement is confirmed, the controller controls the drying drum to rotate in the reverse direction.

[0004] However, when the washing machine rotates forward and backward frequently, there is an intermediate stop time during the rotation switching, which wastes electric resources, the drying is not thorough, and the drying efficiency cannot be improved.

[0005] Therefore, designing a method for judging the entanglement coefficient through the weight of the clothes and the magnitude of the motor current, and adjusting the angle of the lifting rib, the rotation speed and the stop speed of the drum is beneficial to improving the drying efficiency, reducing resource waste, and providing more convenient services for users. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a drying control method for a washing machine. A method for adjusting the angle of the lifting rib, the rotation speed and the stop speed of the drum to change the entanglement coefficient of the clothes can effectively improve the clothes drying efficiency, is beneficial to thorough drying of the clothes, and reduces the drying time.

[0007] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A drying control method for a washing machine, which executes a drying program. The drum rotates at a certain speed for a period of time and then stops. The weight G of the clothes in the drum is obtained, the motor current I when the drum stops rotating is measured, and the entanglement coefficient X of the clothes is judged according to the weight G of the clothes and the motor current I; according to the entanglement coefficient X, the angle J of the lifting rib is adjusted, and the drying program is executed according to the adjusted angle J of the lifting rib.

[0009] Further, after judging the entanglement coefficient X of the clothes, the rotation-stop ratio S of the drum is adjusted according to the entanglement coefficient X, and the drying program is executed according to the adjusted rotation-stop ratio S of the drum.

[0010] Further, a threshold value Y is preset for the winding coefficient X. If it is greater than the threshold value Y, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted; if it is less than the threshold value Y, the drying program is executed.

[0011] Further, after the washing machine executes the drying program for a period of time, the weight G1 of the clothes and the motor current I1 are measured again to obtain the winding coefficient X1. If the winding coefficient X1 is still greater than the threshold value Y, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted; when the winding coefficient X1 is less than the threshold value Y, the drying program continues to be executed.

[0012] Further, the cross-section of the lifting rib is in the shape of an isosceles triangle, and the angles of its two base angles change in real time according to the weight of the clothes. The angles of the two base angles include at least three change values.

[0013] The angle of the lifting rib in the initial state is J1.

[0014] When the winding coefficient X is large, the angle of the lifting rib is increased to J2.

[0015] When the winding coefficient X is small, the angle of the lifting rib is decreased to J3.

[0016] Further, when clothes are added to the drum, the weight G of the clothes in the drum is obtained again. The drum rotates at a certain rotational speed for a period of time and then stops. The motor current I is measured, the winding coefficient X is calculated, and the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted until the winding coefficient X is less than the threshold value Y.

[0017] Further, during the execution of the drying program, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted, and the angle J of the lifting rib and the rotation-stop ratio S of the drum when the winding coefficient X is less than the threshold value Y are recorded.

[0018] Further, the washing machine records the adjusted angle J of the lifting rib and the rotation-stop ratio S corresponding to different winding coefficients X. When the washing machine is used again and the drying program is executed, the angle J of the lifting rib and the rotation-stop ratio S that have been recorded are automatically matched according to the winding coefficient X.

[0019] Further, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted; and the drying program is executed with the adjusted angle J of the lifting rib and the rotation-stop ratio S of the drum. When the winding coefficient X is greater than the threshold value Y, the angle J of the lifting rib and the rotation-stop ratio S of the drum are repeatedly adjusted until the winding coefficient X is less than the threshold value Y.

[0020] Further, when the drying program of the washing machine is used again, it is detected and judged whether the winding coefficient X is the same as the winding coefficient X recorded by the washing machine. If so, the corresponding angle J of the lifting rib and the rotation-stop ratio S are matched; if not, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted according to the winding coefficient X. After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0021] 1. Automatically adjusting the angle of the lifting ribs and the drum rotation stop ratio can effectively disperse the entangled clothes, avoiding the problem of incomplete drying caused by clothes entanglement. This helps to ensure that the clothes can be fully exposed to the hot air during the drying process, thereby improving the drying effect.

[0022] 2. By using the inertial current and the weight of the clothes to determine whether the clothes are entangled, this method enables the drum washing machine to more intelligently monitor the state of the clothes, thereby achieving automatic adjustment and processing, and improving the efficiency and convenience of the drying process.

[0023] 3. This method helps to extend the service life of the clothes and the drum washing machine, because it avoids the damage or wear of the drum that may be caused by clothes entanglement, and at the same time reduces the need for users to manually intervene due to clothes entanglement, improving the user experience.

[0034] Embodiment 1

[0035] A drying control method for a washing machine, after the washing is completed, the clothes in the drum are weighed as G, the motor current I when the drum stops rotating after the washing is completed is measured, and the winding coefficient X of the clothes is judged according to the clothes weight G and the motor current I; the angle J of the lifting rib is adjusted according to the winding coefficient X.

[0036] When the drying program starts to execute, the drum rotates at a certain speed for a period of time and then stops. First, the clothes in the washing drum are weighed to obtain the weight G of the clothes. The motor current I when the drum stops rotating is measured, and the winding degree of the clothes, that is, the winding coefficient X, is judged according to the ratio of the clothes weight G and the motor current I.

[0037] The motor current I of the washing machine is generated by the principle of electromagnetic induction. When the washing machine is powered on, the current passes through the electromagnetic coil to generate a magnetic field. In the motor of the washing machine, there is usually a rotor (also called the rotor core) and a stator coil. When the current passes through the stator coil, the generated magnetic field will cause the rotor core to rotate. This is based on the Ampere's rule and the Lorentz force principle, that is, the current will be affected by a force in the magnetic field.

[0038] In the washing machine motor, by controlling the direction and magnitude of the current, the change of the magnetic field can be controlled, and then the rotation of the rotor can be controlled. In this way, the operation of the washing machine motor is realized, driving the inner barrel of the washing machine to rotate, so as to realize the function of washing clothes.

[0039] First, obtain the weight G of the clothes in the drum after the drying program in the washing machine has been executed for a period of time.

[0040] Obtain the motor current I generated by the inertial force on the drum wall when the drum of the washing machine stops rotating. Then the winding coefficient X = I / G.

[0041] Adjust the angle J of the lifting rib according to the magnitude of the winding coefficient X. The lifting rib is a structure inside the washing machine. By adjusting the angle of its cross-section, it can affect the movement trajectory of the clothes during drying, helping to prevent clothes entanglement and ensuring the drying effect.

[0042] Judge the entanglement situation of the clothes based on the clothes weight G and the motor current I, and automatically adjust the angle J of the lifting rib according to this situation, so that the clothes are shaken loose under the acting force of the lifting rib beating, in order to achieve a more effective drying effect and solve the problem of incomplete drying caused by clothes entanglement.

[0043] The lifting rib of the washing machine plays a key role during the washing process. On the one hand, it causes friction with the clothes, and the part of the clothes close to the lifting rib and the relative moving part rub against each other to produce a kneading effect; on the other hand, the lifting rib drives the clothes to rotate together. The clothes are lifted out of the liquid surface and sent to a certain height, and then fall back into the laundry detergent again due to the action of gravity, hitting the laundry detergent to produce a rod-beating and falling effect, thereby achieving the washing effect.

[0044] As Figure 2-4 shown, the projection of the cross-section of the lifting rib in the rotating drum is approximately an isosceles triangle. The angle of the lifting rib in the initial state is J1; when the winding coefficient X is relatively large, increase the angle of the lifting rib to J2; it is convenient to lift the clothes higher and shake the clothes loose. When the winding coefficient X is relatively small, reduce the angle of the lifting rib to J3; it is convenient to reduce the friction on the clothes and reduce the loss.

[0045] The lifting rib drives the clothes to lift through friction, achieving the effect of beating and shaking loose. When the current clothes winding coefficient X is large, automatically change the angle of the cross-section included angle of the lifting rib, so that the upward force generated by the lifting rib on the clothes is greater, lift the clothes higher, and the effect of shaking the clothes loose is better.

[0046] The specific steps of this washing machine drying control method are as follows:

[0047] After executing the drying program for a period of time, obtain the weight G of the clothes in the drum: The washing machine can weigh the clothes in the drum according to the weighing sensor to obtain the weight G of the clothes. If there are too many clothes, it may cause the washing machine to be unable to weigh accurately, and error handling is required. Then it is necessary to weigh multiple times, obtain different weight values, and take the average value.

[0048] Obtain the motor current I when the drum stops rotating after washing is completed: At the moment when the drum stops rotating, the gravity of the clothes and the degree of entanglement generate an inertial force that impacts the drum wall. At this time, the measured motor current I is the current at the moment when the gravity of the drum generates an inertial force on the drum wall. The magnitude of the motor current I is related to the entanglement of the clothes. Entangled clothes will increase the load on the motor, thereby increasing the current. It is possible that if there is a fault or other factors inside the washing machine that cause the current to be abnormal, the abnormal situation needs to be handled.

[0049] Judge the entanglement coefficient X of the clothes according to the clothes weight G and the motor current I: Perform a logical calculation on the clothes weight G and the motor current I to obtain a proportional relationship, and judge the degree of entanglement of the clothes according to the proportional relationship to obtain the entanglement coefficient X.

[0050] It is necessary to accurately judge and handle the entanglement coefficient X for different types of clothes and under different washing conditions.

[0051] Different types of clothes include cotton, wool, silk, synthetic fibers, etc. Each type of clothing has different textures and characteristics, and different washing and drying methods are required. Therefore, when using the washing machine drying control method, consider the characteristics and needs of different types of clothes to ensure effective drying of different types of clothes.

[0052] In actual processing, it is necessary to judge the clothing material and washing conditions to avoid damaging or deforming the clothes due to inappropriate washing methods. You can check the washing label on the clothes to understand the material and suitable washing conditions of the clothes.

[0053] Inside the washing machine, clothes of different materials will become entangled to different degrees. This is usually caused by the fiber structure of the clothes and surface friction during the drying process.

[0054] For example, cotton clothes usually get entangled with woolen or synthetic fiber clothes. To reduce clothing entanglement, classify the clothes before washing to avoid mixing clothes of different materials. Use a laundry bag, put the clothes that are prone to entanglement into the bag for separate washing and then put them into the washing machine. Select the appropriate washing program and rotation speed to avoid excessive rotation speed causing clothing entanglement.

[0055] As Figure 1 shown, in this embodiment, adjust the angle J of the lifting rib according to the entanglement coefficient X: According to the magnitude of the entanglement coefficient X, the washing machine automatically adjusts the angle J of the lifting rib.

[0056] Adjust the angle of the lifting rib to J: According to the weight of the clothes G and the winding coefficient X, calculate the lifting rib angle J = f(G, X). The larger the winding coefficient, the larger the angle of the lifting rib, because the larger the angle of the lifting rib, the better the effect of shaking the clothes loose. However, the angle is related to the weight. When the clothes are heavier, the angle should be adjusted accordingly to avoid damage to the drum and the lifting rib during rotation due to the large angle with heavy clothes.

[0057] By monitoring the weight of the clothes G and the motor current I, the washing machine can judge the winding situation of the clothes in real time and adjust the angle J of the lifting rib accordingly to reduce the winding between the clothes. This helps to protect the clothing fibers, extend the service life of the clothes, and at the same time reduces the trouble for the user to untangle the clothes when taking them out.

[0058] According to the winding situation of the clothes, the intelligent washing machine can adjust the rotation-stop ratio S of the drum so that the clothes can be heated more evenly during the drying process, achieving a more effective drying effect. This can reduce the drying time, save energy, and at the same time maintain the texture of the clothes. It improves the user experience. Helps to extend the service life of the clothes, save energy, and conforms to the concept of sustainable development.

[0059] After the angle J of the lifting rib is adjusted to a certain value, adjust the rotation-stop ratio S of the drum according to the winding coefficient X.

[0060] Rotation-stop ratio S of the drum: According to the weight of the clothes G and the winding coefficient X, calculate the rotation-stop ratio S of the drum S = f(G, X). The larger the winding coefficient, the greater the required rotational speed of the drum, because a high rotational speed and quick stop are convenient for lifting and shaking the clothes loose. However, the rotational speed is related to the weight to avoid damage to the drum caused by heavy clothes and too high a rotational speed.

[0061] Sensor detection: Use sensors to detect the angle J of the lifting rib and the winding coefficient X. The sensors can be angle sensors, pressure sensors, etc., for real-time monitoring of relevant values.

[0062] Control algorithm design: According to the detected values of the angle J of the lifting rib and the winding coefficient X, design a control algorithm to adjust the rotation-stop ratio S of the drum.

[0063] Motor control: Control the rotational speed and stop of the motor according to the result output by the control algorithm.

[0064] Feedback control: Feed back the actual rotational speed and stop state of the motor to the control system of the washing and drying equipment to ensure that the rotation-stop ratio S of the drum meets the requirements.

[0065] Preset a threshold value Y for the winding coefficient X. If it is greater than the threshold value Y, then adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum; if it is less than the threshold value Y, then no adjustment is required.

[0066] The entanglement coefficient X being greater than the threshold value Y indicates a state in which the washing machine detects that the clothes are entangled to a certain extent.

[0067] The setting of threshold value Y ensures that there will be no serious entanglement problem during the drying process. When it is greater than this threshold value, the washing machine will issue an alarm or a prompt sound to indicate that the clothes in the drum are highly entangled during the current drying process. At this time, the washing machine automatically adjusts the angle J of the lifting ribs and the rotation-stop ratio S of the drum. After adjustment, the entanglement coefficient X can be repeatedly measured, and the angle J of the lifting ribs and the rotation-stop ratio S of the drum can be repeatedly adjusted until the entanglement coefficient X is less than the threshold value Y, indicating that the clothes have been shaken loose, and the alarm is lifted or the prompt sound is cancelled.

[0068] Specifically, the winding coefficient X is calculated by monitoring the laundry weight G and the motor current I. Then, the winding coefficient X is compared with a preset threshold value Y.

[0069] If the entanglement coefficient X is greater than the threshold value Y, the washing machine will automatically adjust the angle J of the lifting ribs and adjust the drum's rotation and stop ratio S to reduce the entanglement of the clothes. This can more effectively solve the problem of clothing entanglement and improve the efficiency and washing effect of the washing machine.

[0070] If the entanglement coefficient X is less than the threshold value Y, the washing machine does not need to be adjusted and can continue the washing and drying process. Intelligent clothing entanglement processing can be achieved, the intelligence level of the washing machine can be improved, and the user experience can be enhanced.

[0071] After the washing machine executes the drying program for a period of time, it measures the clothing weight G1 and the motor current I1 again to obtain the winding coefficient X1. If the winding coefficient X1 is still greater than the threshold value Y, the angle J of the lifting rib and the rotation-stop ratio S of the drum are adjusted; when the winding coefficient X1 is less than the threshold value Y, the drying program continues.

[0072] Check whether the winding coefficient X1 is greater than the threshold Y.

[0073] If the winding coefficient X1 is greater than the threshold Y, the adjustment process is entered.

[0074] If the first adjustment of the angle J of the lifting rib and the rotation-stop ratio S of the drum cannot make the winding coefficient X less than the threshold value Y, a secondary adjustment is required.

[0075] The clothing weight G1, motor current I1, and winding coefficient X1 measured again are all obtained by adjusting the angle J of the lifting ribs and the rotation-stop ratio S of the drum based on the winding coefficient X obtained in the previous detection, and then detecting the winding coefficient X1 again.

[0076] Start adjusting the angle J of the lifting rib and the rotation-stop ratio S of the drum. If the second adjustment of the angle J of the lifting rib and the rotation-stop ratio S of the drum still does not make the winding coefficient X1 less than the threshold value Y, it is necessary to detect the winding coefficient X2 again and determine whether it is greater than the threshold value Y. If so, adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum again. After the adjustment, if the winding coefficient X2 is less than the threshold value Y, continue to execute the drying program.

[0077] When the winding coefficient X is less than the threshold value Y, it indicates that the current clothes have been shaken out, which is convenient for thorough drying, and the drying program is executed.

[0078] The drying program should ensure completion within an appropriate temperature and time, while avoiding over-drying and damaging the clothes.

[0079] When clothes are added to the drum, re-obtain the weight G of the clothes in the drum. The drum rotates at a certain rotational speed for a period of time and then stops. Measure the motor current I, calculate the winding coefficient X again, and adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum again until the winding coefficient X is less than the threshold value Y.

[0080] The washing machine records the winding coefficient X corresponding to different clothes weights G, and the adjusted angle J of the lifting rib and the rotation-stop ratio S of the drum corresponding to different winding coefficients X. When the drying program is used again, it is automatically adjusted according to the winding coefficient X.

[0081] The larger the winding coefficient X, the larger the rotation-stop ratio S of the drum is adjusted. The washing machine records the adjusted rotation-stop ratio S of the drum under this winding coefficient X;

[0082] The rotation-stop ratio of the washing machine drum refers to the ratio between the rotation and stop speeds of the drum during the washing process. Usually, the higher the rotation-stop ratio, the longer the stopping time of the drum. To calculate the rotation-stop ratio, the following formula can be used:

[0083] Rotation-stop ratio = (Stop time / (Stop time + Rotation time)) * 100%

[0084] Among them, the stop time is the time when the drum stops rotating, and the rotation time is the time when the drum rotates during the washing process.

[0085] For example, if during the washing process of the washing machine, the stop time of the drum is 20 seconds and the rotation time is 60 seconds, then the rotation-stop ratio is: (20 / (20 + 60)) * 100% = (20 / 80) * 100% = 25%. Adjusting the rotation-stop ratio of the washing machine drum can affect the degree of clothes winding. The higher the rotation-stop ratio, the longer the stopping time of the drum, and the frictional force and pulling force during the washing process will be reduced, thereby reducing the degree of clothes winding. This is particularly important for washing soft and easily wound clothes (such as sweaters, underwear, etc.).

[0086] A lower rotation-stop ratio will increase the friction and pulling force during the washing process, which may cause more serious entanglement of the clothes. Adjusting the rotation-stop ratio of the washing machine drum can effectively reduce the degree of clothes entanglement.

[0087] While adjusting the angle J of the lifting rib, correspondingly change the rotation-stop ratio S of the drum. After the drum rotates again, calculate the entanglement coefficient X, and determine whether the entanglement coefficient X is greater than the threshold value Y. If it is greater, continue to adjust; if it is less, record the value of the angle J of the lifting rib and the rotation-stop ratio S of the drum corresponding to the entanglement coefficient X.

[0088] The clothing materials used in the current season and the number of clothes to be dried affect the weight G of the clothes. When the number of clothes is large but the weight G is small, the detected entanglement coefficient X is greater than that when the number of clothes is small but the weight G is large.

[0089] Adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum; and execute the drying program with the adjusted angle J of the lifting rib and the rotation-stop ratio S of the drum. When the entanglement coefficient X is greater than the threshold value Y, repeatedly measure the entanglement coefficient X and adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum until the entanglement coefficient X is less than the threshold value Y.

[0090] Repeatedly detect the entanglement coefficient X. After obtaining a more accurate value, repeatedly adjust the angle J of the lifting rib and the rotation-stop ratio S of the drum to ensure that the clothes can be evenly and fully dried during the drying process, avoiding uneven clothes entanglement or incomplete drying. Improve the drying effect of the washing machine and provide a better user experience during use.

[0091] When the washing machine drum rotates, it will generate an inertial current. By measuring the characteristics of these inertial currents, it is possible to preliminarily judge whether the current clothes are entangled, and automatically adjust or match the angle J of the lifting rib and the rotation-stop ratio S of the drum corresponding to the previously recorded entanglement coefficient X.

[0092] The washing and drying equipment dynamically measures the entanglement coefficient X during the execution of the drying program, and dynamically measures and adjusts in real time the angle J of the lifting rib of the washing and drying equipment and the rotation-stop ratio S of the drum during the execution of the drying program. Improve the drying effect: Dynamically adjusting the angle J of the lifting rib and the rotation-stop ratio S of the drum according to the real-time entanglement coefficient X can make the drying process more uniform, improve the drying effect, and ensure uniform drying of the clothes. Make the washing and drying equipment more intelligent, capable of intelligent adjustment according to the actual situation, and improve the user experience. Reduce maintenance costs: By reducing the entanglement of the clothes, the failure rate of the washing and drying equipment can be reduced, the service life of the equipment can be extended, and the maintenance costs can be reduced.

[0093] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention can make some changes or modifications to equivalent embodiments with equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention.
