A dehydration control method for optimizing the drum's deviation-correcting action

Abstract

The present invention discloses a dehydration control method for optimizing drum deviation correction, relating to the technical field of drum washing machines. The method comprises the following steps: operating the machine at 90 rpm for eccentricity detection, performing a weighing test based on the eccentricity value, and adjusting the eccentricity and weighing values to a target speed, and then performing dehydration at the target speed. The method first tests the vibration performance limits of the entire machine, then compares the limits with the actual measured OOB limits and speed fluctuations under load, thereby determining the appropriate action for the entire machine to achieve deviation correction, thereby improving the dehydration success rate and reducing the total deviation correction time.

Description

Technical Field

[0001] The present invention belongs to the technical field of drum washing machines, and in particular relates to a dehydration control method for optimizing a drum deviation-correcting action. Background Art

[0002] There are some small loads on the market that are prone to absorbing water. These include bath clothes, baby clothes, and fleece jeans. Especially in the summer, users tend to wash fewer clothes at a time, resulting in only one or two pieces of absorbent clothing in the drum. This condition can easily lead to large eccentricity. Furthermore, the design of washing machine cabinets during home renovations can lead to thinner washing machine bodies, resulting in a larger inner drum diameter. If this problem occurs, dehydration becomes more difficult.

[0003] At this stage, all products are making continuous improvements in this aspect. Most products rely on the forward and reverse rotation of the inner barrel to shake out the clothes before dehydration, hoping that the clothes will be evenly distributed in the barrel and the eccentricity in the barrel will be reduced. The above method can currently achieve the desired correction effect for most loads, but when encountering a pair of fleece jeans or cotton baby clothes, because the clothes are highly absorbent and easy to shrink into a ball, the correction action is difficult to achieve the shaking effect. At the same time, when encountering multiple loads of different materials, some loads will be squeezed in a corner and cannot be shaken out. The specific shortcomings are as follows:

[0004] 1. When a large eccentricity is formed under full load conditions, the eccentricity cannot be effectively reduced;

[0005] 2. The probability of reaching the highest speed during dehydration cannot be guaranteed;

[0006] 3. If a large eccentricity is formed, it will lead to constant correction, resulting in loss of power and time;

[0007] 4. Large eccentricity and high speed will lead to poor user experience and risks in program verification;

[0008] 5. Failure to dehydrate properly will result in excessively high moisture content, affecting the customer experience.

[0009] A dehydration control method for optimizing drum deviation correction is provided. The method first determines the limit of the machine's extreme state. When this limit is met, a short pre-spin is added to complete the dehydration process. This removes some water from the more absorbent clothing in the drum, reducing the eccentricity within the drum and making the load easier to shake loose, allowing for subsequent loosening to complete the dehydration process. Summary of the Invention

[0010] The purpose of the present invention is to provide a dehydration control method for optimizing the drum correction action. By first testing the limit value of the vibration performance of the whole machine, and comparing the limit value with the OOB limit value and the speed fluctuation value actually measured under load, it is determined what action the whole machine should take at this time, and the correction effect is completed, thereby solving the problem that the existing drum eccentricity causes power and time loss and affects the customer experience.

[0011] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0012] The present invention is a dehydration control method for optimizing the drum deviation correction action, comprising the following steps:

[0013] Step 1, start dehydration;

[0014] Step 2, start pre-dehydration;

[0015] Step 3: Run at 90 rpm to perform eccentricity detection;

[0016] Step 4: Determine whether the eccentricity value (OOB) is less than or equal to the eccentricity limit value (A); if so, perform a weighing test; if not, proceed to step 7;

[0017] Step 5: Determine whether the eccentricity value (OOB) and the weighing value (IB) meet the target speed standard. If so, proceed to step 10; if not, the number N = N + 1;

[0018] Step 6, determine whether the number N is less than or equal to 20; if so, return to step 3; if not, proceed to step 12;

[0019] Step 7, perform speed fluctuation detection, and determine whether C < speed fluctuation value (U) < B. If so, proceed to step 8; if not, proceed to step 9;

[0020] Step 8: Run to 180 rpm and maintain for 30 seconds, the number of times N1 = N1 + 1, determine N1 ≤ 3, if yes, return to step 3; if not, increase to 240 rpm and maintain for 30 seconds, return to step 3;

[0021] Step 9: Determine if the speed fluctuation value (U) is less than C. If so, run to 240 rpm and maintain for 30 seconds before returning to step 3; if not, proceed to step 12;

[0022] Step 10, reaching the target speed for dehydration;

[0023] Step 11, start main dehydration;

[0024] Step 12, dehydration is completed.

[0025] The present invention has the following beneficial effects:

[0026] (1) The present invention first tests the limit of the vibration performance of the whole machine, and compares the limit according to the OOB limit and the speed fluctuation value actually measured under load, so as to judge what action the whole machine should take at this time, thereby completing the correction effect, improving the success rate of dehydration, and reducing the total correction time.

[0027] (2) The present invention performs a low-speed pre-stripping within the vibration performance range of the entire machine, with the main purpose of removing water from the clothes. After implementation, the efficiency of subsequent correction actions is improved without affecting the normal clothing washing process and time.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
