Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, and in particular to an eccentricity correction control method for a clothing processing device, a clothing processing device, and a storage medium. Background Art

[0002] A washing machine is an appliance that uses electrical energy to create mechanical action to process clothes.

[0003] When the washing machine is performing high-speed dehydration, it is easy for the uneven distribution of clothes in the barrel and excessive eccentricity to cause the clothing processing equipment to run too noisy, the dehydration vibration to be large, and even the barrel to hit.

[0004] Patent CN118166516A determines whether the eccentricity of the washing machine is too large by judging the current frequency of the washing machine's motor. If it is detected that the eccentricity is too large, the rotation speed is adjusted to prevent problems such as excessive noise and vibration displacement. This patent requires readjustment of the rotation speed to prevent excessive eccentricity, which will cause the washing process to be prolonged. Patent CN117867818A corrects the eccentricity of the washing machine before entering the dehydration stage through cyclic eccentricity detection. This patent method has many detection steps and a long execution process, which will also cause the washing process to be prolonged.

Based on the first difference, determine a first wind speed required to balance the first difference and a corresponding first inner barrel area that needs to provide wind force, and control the operation of the fan currently corresponding to the first inner barrel area to make the wind speed of the first inner barrel area reach the first wind speed.

[0050] In some embodiments, the eccentric force of the whole drum in the laundry processing device may be first obtained, and when the eccentric force is greater than a set threshold, S101 or S102 is executed, otherwise, S101 and S102 are not executed.

[0051] The pressure of each inner barrel area is obtained by a pressure sensor;

[0052] The pressure difference between each inner barrel area and the inner barrel area arranged opposite thereto is determined.

[0053] Optionally, when there are four inner barrel areas in total, the four inner barrel areas are located at four positions, upper, lower, left and right, respectively. For the left and right inner barrel areas, the eccentric force threshold is 0, and for the upper and lower inner barrel areas, the eccentric force threshold is ( + ) g, where m is the mass of the clothes to be processed and M barrel is the mass of the inner barrel.

[0054] Optionally, based on the first difference, determining a first wind speed required to balance the first difference and a corresponding first inner barrel area required to provide wind force includes:

[0055] When the first difference is greater than 0, the inner barrel region corresponding to the first difference and having a larger pressure is determined as the first inner barrel region;

[0058] Determine the radius r of the inner barrel cavity according to the obstruction of the infrared measuring device;

[0060] Optionally, the steps of obtaining the pressure difference in the inner barrel of the clothing processing device and determining a first difference between the pressure difference and the eccentric force threshold are continuously performed during the operation phase of the clothing processing device until the clothing processing device stops operating.

[0061] Optionally, before obtaining the pressure difference in the inner barrel of the clothes processing device, the method further includes:

[0062] Obtaining the weight of the laundry to be processed, and if it is determined that eccentricity correction is required based on the weight of the laundry to be processed, obtaining the set speed of the current washing program;

[0067] like Figure 2 and Figure 3 The figure shows a schematic diagram of the barrel structure of a clothes processing device, in which 101 is an outer barrel, 102 is an inner barrel, and 103 is the bottom of the inner barrel. The bottom of the inner barrel is divided into four parts of equal area, n1, n2, n3, and n4. The corresponding inner barrel is also divided into four parts of equal volume, namely, four inner barrel areas. Figure 2 The partial division in is only an example. In actual application, it can be evenly divided into other numbers of inner barrel areas as needed. 104 is the inner barrel shaft, 105 is the bearing of the inner barrel shaft, and pressure sensors are provided on the bearings in the four directions of n1, n2, n3, and n4 to detect the force difference caused by the eccentricity of the inner barrel. 101 is the outer barrel, 102 is the inner barrel, and the bottom of the inner barrel has a hollow design to facilitate air supply. 108 is an air duct switch and a wind speed sensor, which can be closed when no air is supplied to prevent water from entering the air duct. When air is supplied, the air supply speed can be monitored in real time. 109 is an air supply duct, 110 is an air supply fan, and the wind speed of the fan is adjustable. In the current implementation, there are a total of 4 fans, corresponding to the four areas n1, n2, n3, and n4 respectively. 111 is a wind speed sensor responsible for detecting the wind speed of the outer wall of the inner barrel.

[0068] Figure 4 and Figure 5 The figure shows the inner barrel load diagram. During the high-speed dehydration stage, the clothes in the barrel will Figure 5The shaded part in the middle is also tightly attached to the inner barrel wall, forming a cavity, so there is a cavity radius r (which varies with the quality, material, distribution, etc. of the clothes). An infrared measuring device can be set on the glass bowl or barrel cover of the clothing processing equipment to measure. When the clothes block the infrared sensor, the cavity radius r can be measured according to the blocked part. The radius of the inner barrel is fixed to R. The real-time rotation speed v of the inner barrel is known (unit: r / s, revolutions per second). The linear velocity VR=2πRv (unit: m / s) corresponding to the outer wall R of the inner barrel can be obtained by conversion. The surface area of ​​the inner barrel outer wall corresponding to the n1 area is approximately SR 1 (from the radius R of the inner barrel, we know that the arc length of part n1 is πR / 4, and πR / 4 multiplied by the length of the inner barrel can get the surface area of ​​the outer wall of the inner barrel of part n1, SR1). Similarly, the surface area of ​​the inner barrel cavity is Sr1. The eccentricity of the washing machine during operation is detected by the pressure sensor installed on the inner barrel bearing. When the inner barrel is running at a constant speed v, if the clothes in the barrel are evenly distributed, the n2 and n4 parts of the inner barrel should only be subjected to the centripetal force of the corresponding parts of the inner barrel and the clothes. Then, the pressure on the n1 area is the centripetal force minus the gravity of the corresponding parts of the inner barrel and the clothes, and the pressure on the n3 area is is the centripetal force plus the gravity of the corresponding inner barrel and clothes, so the pressure on each part is about Fn2=Fn4=V^2 / R*(m / 4+M barrel / 4), Fn1=V^2 / R*(m / 4+M barrel / 4)-(m / 4+M barrel / 4)g, Fn3=V^2 / R*(m / 4+M barrel / 4)+(m / 4+M barrel / 4)g, m is the weight of clothes, M barrel is the mass of the inner barrel, g is the acceleration of gravity. To make the inner barrel of the washing machine run in a balanced manner, the pressure difference in the relative area must be Fn4-Fn2=0, Fn3-Fn1= (m / 2+M barrel / 2)g, that is, the eccentric force threshold of n2 and n4 areas is 0, and the eccentric force threshold of n3 and n1 areas is (m / 2+M barrel / 2)g, so that the force on the relative area of ​​the inner barrel is in a balanced state. If the inner barrel is in an eccentric state, the pressure difference in the corresponding area reflects the size of the eccentricity. Taking n1 and n3 areas as an example, when eccentric, Fn3-Fn1=Fc+(m / 2+M barrel / 2)g, Fc is the first difference, indicating that the n3 area is under greater pressure and the eccentricity is biased towards the n3 direction. At this time, if n1 and n3 need to maintain relative balance, the air pressure (PR) of the outer wall of the n3 part needs to be greater than the air pressure (Pr) of the internal cavity, and the air pressure difference needs to be equal to Fc, that is, PR*SR1-Pr*Sr1=Fc needs to be satisfied. Assume that the wind speed outside the barrel is Vw, and the wind speed inside the barrel is Vn (the wind speed inside and outside the barrel can be measured by the wind speed sensor), then according to the Bernoulli equation, we can get P0=Pr+(ρVn^2) / 2=PR+(ρVw^2) / 2, P0 is the standard atmospheric pressure, ρ is the air density. Based on the above, we can know that in order to balance the two symmetrical areas n1 and n3, the air flow rate on the cavity surface of the n3 area of ​​the inner barrel needs to be greater than the flow rate on the outer wall of the n3 area, so that the outer wall pressure PR is greater than the cavity pressure Pr, that is, it satisfies (When this condition is met, the forces in the n1 and n3 regions are balanced and there will be no eccentricity. The same is true for the n2 and n4 regions.) According to the above formula, the inner barrel wind speed Vn required for balance can be calculated based on other known values. The wind speed Vn is supplied to the barrel by controlling the fan in the corresponding area and the wind speed is controlled to Vn. After determining an initial Vn, the corresponding wind speed Vn can be adjusted in real time according to the eccentricity of the barrel (that is, the first difference Fc in the corresponding area). If the eccentricity value is too large, the wind speed is increased. If the eccentricity value is small, the wind speed is reduced. The equation is always satisfied. .

[0069] In actual applications, the inner barrel rotates, but the eccentricity caused by the rotation of the inner barrel will have a bias, which will eventually force the inner barrel to lean towards one direction. Figure 2 As shown, the inner barrel is evenly divided into four parts, namely n1, n2, n3, and n4. These four parts and their corresponding air ducts, fans, pressure sensors, etc. are in fixed positions and do not change with the rotation of the inner barrel. When the inner barrel becomes eccentric and leans toward a certain direction, the pressure on this area will be greater and will be detected by the pressure sensor.

[0070] like Figure 6 As shown, when the clothing processing device enters the washing program, it first obtains the weight m of the washed clothes and the dehydration speed Vt set for the washing program, and correspondingly obtains the set threshold value Bv of the eccentric force required for the set speed (the higher the speed of the clothing processing device, the smaller the eccentricity value required. If the eccentricity is large, forcing the speed to increase will cause phenomena such as hitting the barrel and shifting. Therefore, each speed requires a limited set threshold value of eccentric force to prevent hitting the barrel and shifting), and detects the speed v of the barrel in real time. If the weight m of the clothes is less than the preset value Mmin (taking a 10kg washing machine as an example, the preferred value is 1kg), it is determined that the weight of the clothes is too light, and there is no need to correct the eccentricity, and the correction program is terminated directly. If m>Mmin, when entering the dehydration program, the clothes are shaken and distributed normally. When the dehydration enters the speed-up stage, the clothes will be close to the barrel wall, such as Figure 5As shown in the shaded part, at this time, the actual inner barrel diameter r is obtained, and the pressure Fn in the four directions of the inner barrel n1 to n4 is detected at the same time (n is 1, 2, 3, 4, corresponding to 4 areas), the outer barrel wind speed Vw and the inner barrel wind speed Vn are detected, and the eccentric force B in the inner barrel of the clothing processing device and the set eccentric force threshold Bv are compared in real time. If B≤Bv is always satisfied, the normal dehydration program is executed until the dehydration is completed. If B>Bv, the inner barrel area that needs to be compensated is calculated according to the pressure Fn of the four relative areas, and the first difference Fc that needs to be compensated is calculated, and then according to the mass m of the clothes, the inner barrel is The barrel diameter R, inner barrel mass M barrel, standard atmospheric pressure P0, air density ρ, real-time test rotation speed v, cavity radius r, inner barrel outer wall wind speed Vw are used to calculate the initial wind speed Vn in the barrel. The fan in the corresponding area is controlled to start so that the wind speed in the barrel in this area reaches Vn. The size of Vn is adjusted in real time according to the value of Fc. For symmetrical areas such as n1 and n3, only the fan in the area with a large relative eccentricity value (that is, the area with a large pressure Fn) is turned on to balance the force on the barrel in the symmetrical area, so that B is always less than the set threshold value Bv of the set eccentricity, and B≤Bv is maintained until the end of the dehydration stage.

[0071] In an embodiment of the present application, air is supplied to the severely eccentric part of the inner barrel according to the eccentricity in the barrel of the clothing processing device during high-speed dehydration, so that the air flow rate in the severely eccentric part of the barrel is higher than the air flow rate of the outer wall of the inner barrel. The pressure is low where the air flow rate is high, the air pressure on the outer wall of the inner barrel is greater than that on the inner barrel, and the surface area of ​​the outer wall of the inner barrel is also greater than that on the inner barrel. Therefore, at this time, the pressure on the outer wall of the inner barrel is greater than that on the inner wall of the barrel. This pressure is used to offset the eccentricity of the inner barrel, so that the inner barrel is in a stable operating state. The entire correction process does not require extending the washing process, will not affect the washing time, and has a better user experience.
