[0045] Many laundry treatment devices currently use the change of motor current to estimate the weight of laundry, and the size of current is easily affected by the eccentricity of the inner drum, so the greater the eccentricity, the greater the error, so this weighing method has a large error. Another measurement method is to directly use the deformation of the damper to detect the weight of the laundry in the drum, and this detection method will become inaccurate with the decay of the parameters of the damper. Whether using the change of motor current or using the change of damper to detect the weight of laundry in the drum, there will be problems such as large error and poor reliability. The measured weight of laundry will affect the setting of the washing program for the values such as washing water level and dehydration rotation speed, and if the measured value and the actual value differ greatly, it is easy to cause problems such as waste of resources, poor laundry cleaning ratio, poor dehydration effect, etc. To avoid the various problems caused by inaccurate weighing of laundry, the first aspect of the embodiment of the present application discloses a weighing method of a laundry treatment device, which includes a damper, as shown in Figure 1 The method includes S1-S3, wherein:
[0046] S1, obtaining a first deformation of the damper after the load is put into the laundry treatment drum;
[0047] S2, accelerating the laundry treatment drum to a preset rotation speed, detecting the weight of laundry in the drum by using the current measurement method to obtain the measured weight of laundry; detecting the second deformation of the damper to determine the change rate of the deformation of the damper;
[0048] S3, determining a correction coefficient according to the deformation of the damper and the corresponding change rate of the deformation to correct the measured weight of laundry to obtain the actual weight of laundry in the drum.
[0049] The damper of the drum washing machine is generally arranged at the bottom of the drum, and can also be arranged at the middle part of the drum on both sides and at the top, and has the functions of buffering and supporting the inner drum, and thus the deformation of the damper can feedback the related parameters of the weight of laundry in the drum. The number of dampers is at least one, and is generally 2-6, and can be arranged at the top, middle and bottom of the drum according to different designs of the whole machine. The position of the damper is not limited in the embodiment of the present application, as long as it meets the functional requirements of supporting and buffering.
[0050] The laundry treatment device includes a washing machine, a dryer, a washing-drying integrated machine, etc., and the drum washing machine is preferred in the following description. The change rate of deformation is the average value of the change values of the deformations of all dampers in unit time, and reflects the size of the eccentricity of the inner drum and the size of the measurement error of the weight of laundry.
[0051] In the current measurement method, the error is mainly caused by the inner drum eccentricity, which is related to the weight of the laundry, and the change rate of the deformation amount of the damper (denoted as ΔX) reflects the size of the inner drum eccentricity (i.e. the error) and is proportional to the size of the error. When the inner drum rotates at a set measurement speed S, with the increase of the actual weight of the laundry (denoted as Ms), the inner drum eccentricity first increases and then decreases, and the error of the measured weight of the laundry (denoted as Mc) also first increases and then decreases. Therefore, the change rate of the deformation amount of the damper can be used to represent the change of the measurement error, and the error of the current measurement method can be eliminated by using the relationship.
[0052] As shown in Figure 2 the error of the measurement can be mainly divided into three regions according to its change characteristics during the gradual increase of Ms. When the laundry is very little (0-M1), the influence of the laundry on the inner drum is very small when the inner drum rotates, the eccentricity is very small at this time, and the corresponding error is also very small and can be ignored. When the laundry is relatively more and tends to M2, since the mass of the laundry is large at this time, and the full load has not been reached, the eccentricity is large when the inner drum rotates, which leads to the overlarge motor current, and the measurement error increases with the increase of the measured mass. The error reaches the maximum at the value of M2, and ΔX is also the maximum at this time. When the mass of the laundry exceeds M2 and approaches the full load (M3 is the full load mass), since the mass of the laundry is large, the influence of the eccentricity on the error relative to the mass of the laundry becomes small, so the error decreases with the mass in the interval of M2-M3. When the actual mass of the laundry is M1, the first deformation amount L1 of the damper can be measured when the laundry drum is static, which is used as a standard value (denoted as the deformation amount setting value) for judgment and comparison. Of course, with the increase of the use time, the damping coefficient of the damper will have a corresponding attenuation, and the actual value of L1 will be larger than the measured value at that time, and the attenuation of the parameters of the damper needs to be corrected.
[0053] The weighing method provided by the embodiment of the present application can measure the first deformation amount of the damper when the laundry is processed, which reflects the relative weight of the laundry in the drum. Then the laundry processing drum is accelerated to a preset speed, the current measurement method is used to detect the weight of the laundry in the drum, and the second deformation amount of the damper at the preset speed is detected, so that the deformation amount of the damper and the change rate of the deformation amount (which reflects the size of the inner drum eccentricity (i.e. the error)) can be determined. The correction coefficient is determined according to the deformation amount of the damper and the change rate thereof, the measurement error of the weight of the laundry is corrected in real time, the measurement error caused by the current change, the attenuation of the parameters of the damper and the like is reduced, and the weight of the laundry is measured more accurately. Since the change rate of the deformation amount of the damper is measured in real time in the present application, the error of the current measurement method is corrected, and the weight of the laundry is calculated in real time by combining the two variables, so that the measurement is more accurate, real-time and reliable.
[0054] In one implementation manner of the embodiment of the present application, the change rate of the deformation amount of the damper is measured in real time, the error of the current measurement method is corrected, and the weight of the laundry is calculated in real time by combining the two variables. Figure 3, S3 corrects the measured weight of the clothes according to the deformation of the damper and the corresponding deformation rate, comprising S31-S32, wherein:
[0055] S31, compares the deformation with the deformation setting value, and compares the deformation rate with the deformation rate setting value;
[0056] S32, in the case that the deformation is greater than the deformation setting value and the deformation rate is greater than the deformation rate setting value, corrects the measured weight of the clothes according to the deformation and the deformation rate.
[0057] When the actual weight of the clothes is M1, the average deformation of the damper can be measured as L1 when the washing machine is at rest, which is used as a standard value for comparison and is recorded as the deformation setting value; the deformation rate setting value is an experimental value or an empirical value, which is used as a standard value for judging the error size and is recorded as ΔL1.
[0058] The deformation of the damper (recorded as X) is compared with the deformation setting value, and the deformation rate (recorded as ΔX) is compared with the deformation rate setting value. If X>L1 and ΔX>ΔL1 are satisfied, it means that the weight of the clothes is relatively large and the measurement error is relatively large, so the measured weight of the clothes needs to be corrected according to the deformation and the deformation rate to obtain the actual weight of the clothes in the drum.
[0059] Further, in combination with Figure 3 The method further comprises S33-S34, wherein:
[0060] S33, in the case that the deformation is less than or equal to the deformation setting value and the deformation rate is less than or equal to the deformation rate setting value, the measured weight of the clothes is taken as the actual weight of the clothes in the drum;
[0061] If X≤L1 and ΔX≤ΔL1 are satisfied, it means that the weight of the clothes, the eccentricity in the drum, and the measurement error are all very small, and the error can be ignored, so the measured weight parameter can be directly used for the subsequent washing program (M=Mc).
[0062] S34, in the case that the deformation is greater than the deformation setting value and the deformation rate is less than or equal to the deformation rate setting value, the measured weight of the clothes is taken as the actual weight of the clothes in the drum;
[0063] If X>L1 and ΔX≤ΔL1 are satisfied, it means that the eccentricity in the drum and the measurement error are very small, which actually reflects that the actual weight of the clothes is very small, so the deformation measured by the damper should be very small, but the actual deformation of the damper is very large, which can only be caused by the attenuation of the damping coefficient. Therefore, the judgment condition provided by the embodiment can judge whether the damping coefficient is attenuated. The attenuation of the damping coefficient causes the measured value X to be greater than the deformation setting value L1, but the measurement error of the weight of the clothes is very small, so "M=Mc" is sufficient.
[0064] Furthermore, combined with Figure 3 The method also includes S35:
[0065] S35, if the deformation is less than or equal to the deformation set value and the deformation rate of change is greater than the deformation rate set value, a fault warning will be issued and the program will be stopped;
[0066] If X≤L1 and ΔX>ΔL1, it means that the damper deformation is very small. However, when the inner cylinder rotates, the current detection error is very large. This may indicate that the cylinder structure is unstable or that the sensor or damper is malfunctioning. Therefore, a warning is issued and the program is stopped to prevent the clothing processing equipment from malfunctioning due to installation problems and to ensure the reliability of the weighing detection.
[0067] Furthermore, the method also includes:
[0068] The deformation setpoint and deformation rate setpoint can be modified and adjusted according to the type of clothing processing equipment, running time, and damper structure.
[0069] In one implementation of this invention, step S3 involves determining a correction coefficient based on the deformation of the damper and its corresponding rate of change of deformation, correcting the measured weight of the clothing, and obtaining the actual weight of the clothing inside the garment. This includes steps A1 to A2, wherein:
[0070] A1, calculate the correction coefficient based on the deformation and the rate of change of the deformation;
[0071] A2, correct the measured weight of clothing according to the correction factor.
[0072] If the damping coefficient decreases with increasing usage time, it will lead to inaccurate measurements of deformation X and the rate of change of deformation ΔX. A correction factor can eliminate the effect of damping coefficient decay, thus reflecting the true error. This true error is used to correct the error in current detection, resulting in a more accurate weighing value and avoiding various problems caused by inaccurate clothing weighing.
[0073] In one implementation of this invention, the actual weight of the clothes inside the tube is calculated using the following formula:
[0074]
[0075] M = K1 × Mc;
[0076] X = X1 - X0;
[0077] Where K1 represents the correction coefficient, X1 represents the second deformation, X0 represents the first deformation, X represents the deformation, ΔX represents the rate of change of the deformation, K represents the measurement error proportionality coefficient, K>0, M represents the actual weight of the clothes in the tub, and Mc represents the measured weight of the clothes obtained by the current measurement method.
[0078] Because the measured values with errors caused by the eccentricity inside the bucket or the attenuation of the damper coefficient are all greater than the actual values, the correction values must be less than the measured values, 0 < K1 < 1.
[0079] Since the value of X reflects the magnitude of M, and X is proportional to M, K is the damping attenuation correction coefficient, and the value of (X+KΔX) reflects the magnitude of Mc, and (X+KΔX) is proportional to Mc, under the condition that other conditions remain unchanged, the smaller the damping coefficient, the larger the values of X and (X+KΔX). Therefore, the influence of the damping coefficient can be eliminated by dividing "X / (X+KΔX)", thereby obtaining the accurate value of M.
[0080] In one implementation of this invention, S1 obtains the first deformation of the damper after the load is applied to the clothing handling tub, including S11 to S12, wherein:
[0081] S11, execute the shakeout procedure;
[0082] S12, bring the clothing processing drum to a standstill and obtain the first deformation of the damper.
[0083] When weighing is required during garment processing, the garment processing drum is kept stationary. The first deformation of the damper is measured while the drum is stationary; this value reflects the relative weight of the garment inside the drum (the value X is affected by the damping coefficient; for the same weight, the smaller the damping coefficient, the larger X). Then, the motor is controlled to accelerate the garment processing drum. When the drum reaches the set rotational speed S, the garment mass Mc is measured using a current measurement method, and the second deformation of the damper is measured again. The difference between the deformation of the damper when the drum is stationary and when it reaches the set rotational speed is calculated to obtain the change in deformation. The rate of change of deformation ΔX is obtained by dividing the change in deformation by the duration of change. ΔX reflects the change in damper deformation per unit time, indicating the magnitude of the inner drum eccentricity and the error in garment weight measurement.
[0084] The principle of the current measurement method is as follows: The inner drum rotates at a set speed S. The greater the weight of the clothes inside the drum, the greater the resistance to the inner drum, and the greater the force and motor current required for the motor to drive the inner drum. By detecting the change in motor current at the set speed S, the weight of the clothes inside the drum can be calculated.
[0085] In one specific implementation, the rotational speed S is set to an adjustable range, generally 30 to 70 rpm, such as 30, 40, 50, 60, 70, etc., with 60 rpm being the preferred value.
[0086] In one implementation of this invention, multiple dampers are provided, and the deformation of the dampers is obtained by:
[0087] Obtain the deformation of each damper and calculate the average value of all damper deformations to obtain the damper deformation.
[0088] Specifically, the garment processing equipment also includes multiple displacement sensors, which can measure the deformation of multiple dampers one by one. The controller calculates the average value of the deformation of all dampers to obtain the deformation X of the damper.
[0089] In one implementation of this invention, step S2 involves detecting the second deformation of the damper and determining the rate of change of the damper's deformation, including steps S21 to S22, wherein:
[0090] S21, calculate the difference between the deformation of each damper at the set speed and the deformation at rest, and obtain the deformation change of each damper;
[0091] S22, calculate the average value of the deformation change of all dampers and the quotient of the time to obtain the deformation change rate.
[0092] The deformation change rate ΔX is the average value of the deformation change of all dampers per unit time, reflecting the size of the inner tub eccentricity and the magnitude of the measurement error of the clothing weight.
[0093] When weighing clothes, first quickly shake them to distribute them evenly in the drum and prevent them from tangling and affecting the measurement results. Then stop the motor until the drum comes to a complete stop. At this point, a displacement sensor can be used to measure the average deformation X of multiple dampers in the washing tub. This value reflects the relative weight of the clothes in the drum. Comparing X with the set deformation value can determine if the weight of the clothes is too large. Comparing the rate of change of deformation with the set deformation rate can determine if the error is too large. Combining the results of the weight judgment and the error judgment, it can be determined whether the current detection result needs to be corrected. If the weight of the clothes is large and the error is also large, the weight of the current detection needs to be corrected. If the error is small, the weight of the current detection does not need to be corrected. Further combining the results of the weight judgment can also determine the attenuation of the damping coefficient. Specifically, if the weight of the clothes is judged to be large but the error is small, it is considered that the deformation measurement value is greater than the deformation set value due to the attenuation of the damping coefficient. If the weight of the clothes is very small and the error is also small, the error can be ignored. In addition, if the weight of the clothing is judged to be large but the error judgment is small, a fault reminder can be issued and the program can be stopped to avoid problems caused by unstable drum structure.
[0094] Specifically, the logic diagram for weighing clothing is as follows: Figure 2As shown. When weighing clothes, first shake the clothes quickly to prevent them from getting tangled and affecting the measurement results. Then stop the motor until the inner tub comes to a stop. Use a displacement sensor to measure the average deformation X of multiple dampers in the washing tub. This value reflects the relative weight of the clothes in the tub (the value of X is affected by the damping coefficient. For the same weight, the smaller the damping coefficient, the larger X is). Next, accelerate the inner tub to a speed of S rpm (set to 60 rpm). Measure the weight of the clothes (Mc) using the current measurement method. Simultaneously measure the average rate of change of deformation of multiple dampers in the washing machine (ΔX is the average value of the change in deformation of all dampers per unit time, reflecting the size of the inner tub's eccentricity and the magnitude of the measurement error in the weight of the clothes). First, determine if "X ≤ L1 and ΔX ≤ ΔL1?". If this condition is met, it indicates that the weight of the clothes, the eccentricity of the tub, and the measurement error are all very small, and the error can be ignored. The measured weight parameters can be directly used for subsequent washing programs (M = Mc). If this condition is not met, determine if "X > L1 and ΔX > ΔL1?". If this condition is met, it indicates that the weight of the clothes is large, and the measurement error is large. Use the equation "M = McX / (X + KΔX)" to correct the measurement error, where K is the correction coefficient, and X reflects the weight of the clothes. The value of M, and the value of (X+KΔX) reflect the value of Mc. The advantage of this formula is that if the damping coefficient decreases with the increase of usage time, resulting in inaccurate measurement of the values of X and ΔX, then "X / (X+KΔX)" can eliminate the influence of the damping coefficient by dividing (the values of X and ΔX are both proportional to the damping coefficient), thus reflecting the true measurement error. If "X>L1 and ΔX>ΔL1?" is not satisfied, then "X>L1?" is judged. If this condition is satisfied, it means "X>L1 and ΔX≤ΔL1", and the decrease of the damping coefficient causes the measured value of X to be greater than the original set value L1, but the impact on the measurement error of the weight of clothing is very small. Let "M=Mc" be sufficient. If "X>L1?" is not satisfied, it means "X≤L1 and ΔX>ΔL1", indicating that the bucket structure is unstable or the sensor or damper is abnormal, issuing a warning and stopping the program.
[0095] Taking a 10kg washing machine as an example, the value of M1 is 0.5-1.5kg, with an optimal value of 1.2kg; the value of M2 is 4.5-6.1kg, with an optimal value of 5.6kg; and M3 is the full load weight of 10kg. When using four dampers with a damping force of 120N and a maximum deformation of 160mm (different washing machines and damper structures will also affect the parameters, the following data is for reference only), the value of L1 is 14-23mm, with an optimal value of 20mm; the value of ΔL1 is 8-15mm, with an optimal value of 12mm; and the value of K is 0.13-0.25, with an optimal value of 0.19.
