Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, and specifically provides a washing machine dehydration control method and device, a washing machine and a storage medium. Background Art

[0002] As a major household appliance, drum washing machines have gained consumer recognition for their low energy consumption and high cleaning efficiency, and their market share continues to grow. However, if eccentricity is not accurately detected during the spin cycle, high-speed spin operation can occur. This can cause vibration noise from the wash tub and even cause the washing machine to move or collide, resulting in damage.

[0003] The eccentricity detection logic implemented by the drum washing machines currently on the market is that when the clothes are severely entangled and knotted, the eccentricity value will be repeatedly detected in the final dehydration stage until the dehydration time is exhausted and an error code is output. No corresponding dehydration program will be made for different eccentricity values. The meaningless waste of time leads to a significant decrease in power consumption and dehydration efficiency.

[0004] Accordingly, the art requires a new washing machine dehydration control method, device, washing machine and storage medium solution to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects, the present invention is proposed to provide a washing machine dehydration control method, device, washing machine and storage medium that solve or at least partially solve the technical problem in the prior art that the dehydration efficiency of the washing machine is low due to the existence of an eccentric value during the dehydration process.

[0006] In a first aspect, the present invention provides a washing machine dehydration control method, the method comprising:

[0007] Get the weight of the unspun laundry;

[0012] The washing machine is controlled to perform secondary dehydration at the second speed until the dehydration is completed.

[0013] In one technical solution of the above-mentioned washing machine dehydration control method, the “determining the first rotational speed according to the first eccentricity value and the weight” includes:

[0014] determining an eccentricity limit value corresponding to the lowest speed gear according to the weight;

[0015] If the first eccentricity value is smaller than the eccentricity limit value corresponding to the lowest speed gear, the speed of the lowest speed gear is used as the first speed.

[0018] If the second eccentricity value is less than the eccentricity limit value corresponding to the lowest speed gear, the speed of the lowest speed gear is used as the first speed;

[0019] If the second eccentricity value is not less than the eccentricity limit value corresponding to the lowest speed gear, the dehydration program is stopped and a prompt message is output.

[0020] In one technical solution of the above-mentioned washing machine dehydration control method, the step of "obtaining the eccentricity value of the clothes dehydrated for the first time, and determining the second rotation speed according to the eccentricity value of the clothes dehydrated for the first time and the weight" includes:

[0021] Controlling the washing machine to execute a laundry shaking program to obtain a third eccentricity value of the laundry after first dehydration;

[0022] determining an eccentricity limit value corresponding to a maximum speed gear and an eccentricity limit value corresponding to an intermediate speed gear according to the weight;

[0023] According to the magnitude relationship between the third eccentricity limit value and all the eccentricity limit values, the rotational speed of the corresponding speed gear is used as the second rotational speed.

[0024] In one technical solution of the above-mentioned washing machine dehydration control method, the “setting the speed of the corresponding speed gear as the second speed according to the magnitude relationship between the third eccentricity limit value and all the eccentricity limit values” includes:

[0025] If the third eccentricity value is less than the eccentricity limit value corresponding to the highest speed gear, the speed of the highest speed gear is used as the second speed;

[0026] If the third eccentricity value is not less than the eccentricity limit value corresponding to the highest speed gear but less than the eccentricity limit value corresponding to the intermediate speed gear, the speed of the intermediate speed gear is used as the second speed;

[0027] If the third eccentricity value is not less than the eccentricity limit value corresponding to the intermediate speed gear, the fourth eccentricity value of the first dehydrated clothes is obtained, and the second speed is determined according to the size relationship between the fourth eccentricity value and all the eccentricity limit values.

[0028] In one technical solution of the above-mentioned washing machine dehydration control method, the step of "if the third eccentricity value is not less than the eccentricity limit value corresponding to the intermediate speed gear, obtaining the fourth eccentricity value of the clothes for the first dehydration, and determining the second speed based on the magnitude relationship between the fourth eccentricity value and all the eccentricity limit values" includes:

[0033] If the fourth eccentricity value is not less than the eccentricity limit value corresponding to the lowest speed gear, the dehydration program is stopped and a prompt message is output.

[0034] In one technical solution of the above-mentioned washing machine dehydration control method, before the step of "obtaining the weight of the undehydrated clothes", the method further includes:

[0035] After controlling the washing machine to execute a laundry shaking program, obtaining a fifth eccentricity value of the un-spun laundry;

[0037] If yes, the step of "obtaining the weight of the un-dehydrated clothes" is executed; if no, the dehydration program is stopped and a prompt message is output.

[0038] In a second aspect, the present invention provides a washing machine dehydration control device, the device comprising:

[0039] an acquisition module configured to acquire the weight of the undehydrated clothes, the first eccentricity value of the undehydrated clothes, and the eccentricity value of the clothes dehydrated for the first time;

[0040] a control module configured to control the washing machine to execute a clothes shaking program and a clothes dehydration program;

[0041] An analysis module is configured to determine a first rotation speed in a first dehydration stage according to the first eccentricity value and the weight, and to determine a second rotation speed in a subsequent dehydration stage according to the eccentricity value and the weight of the clothes dehydrated for the first time.

[0042] In a third aspect, a washing machine is provided, comprising a processor and a storage device, wherein the storage device is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by the processor to execute the washing machine dehydration control method described in any one of the technical solutions of the above-mentioned washing machine dehydration control method.

[0043] In a fourth aspect, a computer-readable storage medium is provided, which stores a plurality of program codes, wherein the program codes are suitable for being loaded and run by a processor to execute the washing machine dehydration control method described in any one of the technical solutions of the above-mentioned washing machine dehydration control method.

[0044] The above one or more technical solutions of the present invention have at least one or more of the following beneficial effects:

[0045] In the technical solution of the present invention, the first speed of the first dehydration is determined according to the weight of the undehydrated clothes and the first eccentricity value. Most of the water in the clothes can be removed through the first dehydration, so that the subsequent shaking of the clothes can achieve a better distribution effect and thus obtain a more accurate eccentricity value; the second speed is determined according to the eccentricity value of the clothes dehydrated for the first time and the weight of the clothes measured before, and the washing machine is controlled to dehydrate at the second speed until the end. The reasonable second speed is set according to the newly measured eccentricity value, so that the washing machine can set a reasonable execution logic in the presence of the eccentricity value, thereby ensuring that each sub-stage in the dehydration stage can proceed smoothly.

[0046] Furthermore, in implementing the technical solution of the present invention, the eccentricity limit corresponding to the lowest speed gear is determined based on weight. If the first eccentricity value is less than the eccentricity limit corresponding to the lowest speed gear, the speed of the lowest speed gear is used as the first speed. The present invention fully considers that the first eccentricity value of undehydrated clothing with a high water content may be detected inaccurately. Therefore, the speed of the lowest speed gear is set as the first speed for the first dehydration, avoiding the problem of directly setting a higher speed when the clothing is tangled and knotted, which may cause the washing machine to crash into the drum.

[0047] Furthermore, in the technical solution of the present invention, if the first eccentricity value is not less than the eccentricity limit value corresponding to the lowest speed gear, the clothes are shaken out and the second eccentricity value is obtained again. If the second eccentricity value meets the conditions, the first dehydration is performed. If the second eccentricity value still does not meet the conditions, the dehydration program is stopped and a prompt message is output. The present invention performs a second shaking attempt if the first eccentricity value does not meet the conditions. If the conditions are still not met, the dehydration program is stopped in time and a prompt message is output. This not only reduces meaningless energy consumption but also provides timely reminders. After receiving the reminder message, the user can make appropriate adjustments to the clothes, which indirectly improves the dehydration efficiency.

[0048] Furthermore, in the technical solution of the present invention, the third eccentricity value of the clothes dehydrated for the first time is obtained, and the eccentricity limit value corresponding to the highest speed gear and the eccentricity limit value corresponding to the middle speed gear are determined according to the weight. The reasonable second speed is determined by utilizing the size relationship between the third eccentricity value and the eccentricity limit values ​​corresponding to the lowest speed gear, the middle speed gear, and the highest speed gear. The corresponding dehydration speed is matched with the actually measured eccentricity value to ensure the smooth progress of the dehydration process, avoid the problem of hitting the barrel due to the actual eccentricity value being large but the speed being also high, and avoid the problem of poor dehydration effect caused by low dehydration efficiency due to the actual eccentricity value being small but the speed being also low.

[0049] Furthermore, in the technical solution of the present invention, if the third eccentricity value is not less than the eccentricity limit value corresponding to the intermediate gear, the fourth eccentricity value is obtained again after the clothes are shaken out, and the second speed is determined based on the fourth eccentricity value and all the eccentricity limits. In the subsequent dehydration stage, the present invention does not directly set the minimum speed because the third eccentricity value is not less than the eccentricity limit value corresponding to the intermediate speed gear. When the dehydration speed cannot be set to the highest speed or the intermediate speed, the present invention further attempts to lower the eccentricity value by shaking the clothes out again, exploring the possibility of uniform distribution of the clothes within a reasonable number of attempts, avoiding the poor dehydration effect caused by directly abandoning a reasonable number of attempts and directly setting the minimum speed due to a large eccentricity value.

[0050] Furthermore, in the technical solution of the present invention, before dehydration, the washing machine is controlled to execute the clothes shaking program to obtain the fifth eccentricity value, and the fifth eccentricity value is compared with the preset threshold value. If the fifth eccentricity value is not less than the preset threshold value, it can be directly judged that the clothes have serious knotting and entanglement, and the dehydration program is stopped immediately and a prompt message is output. After receiving the reminder message, the user can make appropriate adjustments to the clothes, which indirectly improves the dehydration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for controlling the dehydration of a washing machine according to an embodiment of the present invention. Figure 1 As shown, the washing machine dehydration control method in the embodiment of the present invention mainly includes the following steps S1 to S6.

[0060] Step S1: Obtaining the weight of undehydrated clothes;

[0061] Step S2: After controlling the washing machine to execute the clothes shaking program, obtain the first eccentricity value of the unspun clothes;

[0062] Step S3: determining a first rotational speed according to the first eccentricity value and the weight;

[0063] Step S4: Controlling the washing machine to perform a first dehydration at a first speed;

[0064] Step S5: obtaining the eccentricity value of the clothes first spun, and determining the second rotation speed according to the weight and the eccentricity value of the clothes first spun;

[0065] Step S6: Control the washing machine to a second speed to perform secondary dehydration until the dehydration is completed.

[0066] Based on the above steps S1 to S6, the present invention determines the first speed for the first dehydration according to the weight of the undehydrated clothes and the first eccentricity value. Most of the water in the clothes can be removed through the first dehydration, so that the subsequent shaking of the clothes can achieve a better distribution effect and thus obtain a more accurate eccentricity value; the second speed is determined according to the eccentricity value of the clothes dehydrated for the first time and the weight of the clothes measured previously, and the washing machine is controlled to dehydrate at the second speed until the end. A reasonable second speed is set according to the newly measured eccentricity value, so that the washing machine can set a reasonable execution logic in the presence of an eccentricity value, thereby ensuring that each sub-stage in the dehydration stage can proceed smoothly.

[0067] Please see the attached Figure 2 , Figure 2 FIG. 1 is a flowchart of a method for controlling the dehydration of a washing machine according to an embodiment of the present invention. In this embodiment, the washing machine performs a dehydration operation according to the following steps:

[0068] a. At the beginning of dehydration, the computer board controls the motor to rotate at a speed of V f Perform distribution operation to make the clothes as evenly distributed as possible on the inner drum wall; when the distribution is stable, the frequency converter board transmits the eccentricity value detected by the motor to the computer board, and the computer board compares the eccentricity measurement value Y with the set empty drum maximum eccentricity value Y max Compare; if Y<Y max , then go to step b, otherwise it will directly alarm and prompt the user "Clothes are tangled, please open the door to tidy up the clothes, then close the door and press the start button to re-execute the dehydration program."

[0069] b. The computer board controls the motor to weigh the clothes in the washing machine. The computer board confirms the eccentricity limit values ​​Y1, Y2, and Y3 of the three spin speed gears corresponding to the current clothes weight based on the weighing value and then enters step c.

[0070] c. The computer board controls the motor to rotate at speed V f Perform distribution and compare the measured eccentricity value Y with Y3. If the eccentricity value Y is less than Y3, skip step d and proceed to step e; otherwise, proceed to step d.

[0071] d. The computer board controls the motor to rotate at a speed of V f Redistribute and measure the eccentricity value. If the measured eccentricity value Y is less than Y3, go to step e. Otherwise, directly alarm and prompt the user "Clothes are tangled, please open the door to tidy up the clothes, close the door and press the start button to re-execute the dehydration program."

[0072] e. The washing machine will perform low-speed dehydration according to the minimum spin speed V3 set by the computer board, and after a duration of T (the purpose of this step is to spin off most of the water at a low speed first, which is conducive to improving the distribution effect next time and is more conducive to setting the highest speed) and enter step f.

[0073] f. The computer board controls the motor to rotate at speed V f Distribute and measure the eccentricity value Y. If Y<Y1, the computer board controls the motor to accelerate directly to the highest spin speed V1 until the end; if Y1≤Y<Y2, the computer board controls the motor to accelerate directly to the middle spin speed V2 until the end; if Y≥Y2, enter step g.

[0074] g. The computer board controls the motor to rotate at a speed of V f The eccentricity value Y is distributed and measured. If Y<Y1, the computer board controls the motor to directly accelerate to the highest spin speed V1 until the end; if Y1≤Y<Y2, the computer board controls the motor to directly accelerate to the middle spin speed V2 until the end; if Y2≤Y<Y3, the computer board controls the motor to directly accelerate to the lowest spin speed V3 until the end; if Y≥Y3, an alarm is directly issued and the user is prompted "Clothes are entangled, please open the door to tidy up the clothes, close the door and press the start button to re-execute the dehydration program."

[0075] Through the above steps, the washing machine uses the accurately obtained eccentricity value to match the corresponding dehydration speed, thereby improving the dehydration efficiency. While solving the problems of the washing machine hitting the barrel and shifting due to the eccentricity problem, it also avoids the time and power consumption caused by the excessive eccentricity value of the washing machine during the dehydration stage. When the clothes are tangled, the washing machine promptly issues an alarm and prompt information to avoid the problem of wasting time due to the user's ignorance. Especially for commercial washing machines, dehydration time and efficiency are particularly important.
