Description

[Technical Field]

[0001] This application claims priority from Chinese patent application CN202211326947.2, filed on October 25, 2022, for the invention title "Method, storage medium and electronic device for improving the spin-drying achievement rate of a washing machine," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of household electrical appliances, and in particular to a method for improving the spin-drying achievement rate of a washing machine, a storage medium and an electronic device. [Background technology]

[0003] As people's living standards continue to improve, washing machines have become an essential household appliance and have become very convenient for people's daily lives. Dehydration is a commonly used function in washing machines, which can significantly reduce the moisture content of washed clothes and dry them quickly.

[0004] In conventional drum washing machines, determining whether high-speed spin-drying is possible is basically based on two methods: static eccentricity and dynamic eccentricity. However, to ensure that the entire washing machine does not shift and the internal drum does not collide, the dynamic eccentricity increment is generally set to a conservative value, which often results in low spin-drying achievement or excessively long program times due to frequent load distribution. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention proposes a method, a storage medium and an electronic device for improving the spin-drying rate of a washing machine to solve the problems of the prior art, in which the spin-drying rate is low or the program time is too long due to frequent load distribution when a drum washing machine executes a spin-drying command. [Means for solving the problem]

[0006] According to a first aspect, the present invention provides a method for improving a spin-drying achievement rate of a washing machine, comprising: Step S10: In response to a spin-drying command, the drum is controlled to operate at a first rotation speed until the acquired static eccentricity value becomes smaller than a preset static eccentricity value, thereby performing load distribution; Step S20: determining whether the acquired dynamic eccentricity increment is equal to or less than a preset dynamic eccentricity increment; If the dynamic eccentricity increment is greater than the preset dynamic eccentricity increment, control the drum to operate at a second rotation speed until the acquired dynamic eccentricity increment is no longer greater than the preset dynamic eccentricity increment in step S30; and a step S40 of controlling the drum to operate at a third rotation speed to perform dehydration. The present invention provides a method for improving the spin-drying achievement rate of a washing machine, wherein the first rotation speed<the second rotation speed<the third rotation speed.

[0007] Furthermore, the method for improving the spin-drying achievement rate of the washing machine includes: Step S32: controlling the drum to operate at a second rotation speed for a preset time, and then acquiring a dynamic eccentricity increment; The method further includes step S34 of executing a different spin-drying policy based on a result of comparing the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment with the preset number of times.

[0008] Furthermore, executing a different dewatering policy based on a comparison result between the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment and the preset number of times, If the number of times that the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment is smaller than the preset number of times, the method proceeds to step S10.

[0009] If the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment is not less than the preset number of times, spin-drying is not performed.

[0010] Furthermore, the method for improving a spin-drying achievement rate of a washing machine further includes proceeding to step S40 if the dynamic eccentricity increment is not greater than the preset dynamic eccentricity increment.

[0011] Furthermore, the first rotation speed is 60 to 110 r / min.

[0012] Furthermore, the second rotation speed is 150 to 250 r / min.

[0013] According to a second aspect, the present invention provides an apparatus for improving a spin-drying achievement rate of a washing machine, the apparatus comprising: a driving module; an acquisition module; and a determination module; the drive module is configured to control the drum to operate at a first rotation speed in response to a spin-drying command until the static eccentricity value acquired by the acquisition module becomes smaller than a preset static eccentricity value, thereby performing load distribution; The determination module is configured to determine whether the acquired dynamic eccentricity increment is equal to or less than a preset dynamic eccentricity increment; the driving module is configured to control the drum to operate at a second rotation speed until the dynamic eccentricity increment acquired by the acquisition module becomes no longer larger than the preset dynamic eccentricity increment when the determination module determines that the dynamic eccentricity increment is larger than the preset dynamic eccentricity increment; The driving module controls the drum to operate at a third rotation speed to perform spin-drying when the dynamic eccentricity increment acquired by the acquisition module becomes no larger than the preset dynamic eccentricity increment, thereby providing a device for improving a spin-drying achievement rate of a washing machine.

[0014] According to a third aspect, the present invention provides a computer readable storage medium containing a program, the program executing, during operation, a method for improving spin-drying success rate of the washing machine.

[0015] According to a fourth aspect, the present invention provides an electronic device including a memory in which a computer program is stored and a processor, the processor being configured to execute a method for improving a spin-drying success rate of the washing machine using the computer program. [Effects of the Invention]

[0016] The working principle and beneficial effects of the present invention are as follows.

[0017] In this invention, assuming that the preset dynamic eccentricity increment is set to a conservative value, first, when a drum washing machine performs a high-speed spin cycle, the entire washing machine is displaced, preventing the internal drum from colliding. If the dynamic eccentricity increment is greater than the preset dynamic eccentricity increment, the drum is controlled to operate at a second rotation speed, which increases the vibration frequency of the damper in a short period of time, causing the damper to rapidly heat up through friction. Taking advantage of the damper force characteristics that change with temperature, the damper temperature rises quickly, further stabilizing the damper force, and the dynamic eccentricity of the drum quickly stabilizes, thereby reducing the dynamic eccentricity increment. This ensures that the high-speed spin cycle can be more quickly and effectively met after receiving a spin cycle command, improving the spin cycle success rate and avoiding the problem of excessively long program times due to frequent load distribution.

[0019] In order to allow those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application are described below clearly and completely, accompanied by the drawings in the embodiments of the present application, but it is obvious that the described embodiments are not all embodiments but only some embodiments of the present application.

[0020] It should be noted that the terms "first," "second," etc. in the specification and claims of this application and in the drawings are used to distinguish between similar items without necessarily being used to describe a particular order or priority. It should be understood that such terms may be interchanged where appropriate, such that the embodiments of this application described herein can be practiced in orders other than those shown or described herein. It should be noted that the terms "comprise," "have," and any variations thereof are intended to cover a non-exclusive "inclusion," e.g., of a process, method, system, product, or apparatus of a series of steps or units, and are not necessarily limited to those steps or units explicitly listed, but may also include other steps or units not explicitly listed or inherent in the process, method, product, or apparatus.

[0021] Example 1 The present invention proposes a method for improving the spin-drying achievement rate of a washing machine. As shown in FIG. 1, the method for improving the spin-drying achievement rate of a washing machine includes the following steps:

[0022] In response to a spin-dry command, S10 controls the drum to operate at a first rotation speed until the acquired static eccentricity value becomes smaller than a preset static eccentricity value, thereby distributing the load.

[0023] In one embodiment, when a drum washing machine receives a spin command, it controls the drum to operate at a first rotation speed and performs load distribution to ensure that clothes inside the drum are evenly attached to the drum wall. After the drum has operated at the first rotation speed for a while, it compares the current static eccentricity value with a preset static eccentricity value. If the static eccentricity value is smaller than the preset static eccentricity value, it indicates that the current static eccentricity value parameter has reached the standard, and a dynamic eccentricity increment determination can be made. If the static eccentricity value is equal to or greater than the preset static eccentricity value, it indicates that the current static eccentricity value parameter has not reached the standard, and it continues to control the drum to operate at the first rotation speed and perform load distribution until the static eccentricity value reaches the standard.

[0024] In step S20, it is determined whether the acquired dynamic eccentricity increment is greater than a preset dynamic eccentricity increment.

[0025] In one embodiment, the preset dynamic eccentricity increment may still be set to a conservative value to ensure that the entire washing machine does not displace and cause the internal drum to collide when the drum washing machine is in high-speed spin-dry mode. Therefore, after performing the load distribution on the drum, the dynamic eccentricity increment is compared with the preset dynamic eccentricity increment.

[0026] If the dynamic eccentricity increment is greater than the preset dynamic eccentricity increment, S30 controls the drum to operate at a second rotation speed until the acquired dynamic eccentricity increment is no longer greater than the preset dynamic eccentricity increment.

[0027] In one embodiment, as shown in Figure 2, if the dynamic eccentricity increment is greater than the preset dynamic eccentricity increment, the drum is controlled to operate at a second rotation speed and the damper is preheated. If the dynamic eccentricity increment is greater than the preset dynamic eccentricity increment, it indicates that the current dynamic eccentricity increment does not meet the standard and high-speed dehydration is not possible. Therefore, the drum is controlled to operate at a second rotation speed, which quickly increases the temperature of the damper and further stabilizes the damper force, causing the dynamic eccentricity of the drum to quickly approach a stable value, thereby reducing the dynamic eccentricity increment.

[0028] In step S32, the dynamic eccentricity increment is obtained after controlling the drum to operate at the second rotation speed for a preset time.

[0029] In one embodiment, after preheating the damper, the dynamic eccentricity increment is rapidly reduced to match the high-speed spin condition. The acquired dynamic eccentricity increment is again determined to be greater than the preset dynamic eccentricity increment. If the acquired dynamic eccentricity increment is equal to or less than the preset dynamic eccentricity increment, the drum is controlled to operate at a third rotation speed to perform spin-drying. If the dynamic eccentricity increment is still greater than the preset dynamic eccentricity increment after preheating the damper, the process returns to step S10, where the drum is controlled to operate at the first rotation speed to perform load distribution. This avoids the situation where the first load distribution is insufficient, resulting in uneven distribution of clothes in the drum and resulting in a large dynamic eccentricity increment.

[0030] In step S34, a different spin-drying policy is executed based on a result of comparing the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment with the preset number of times.

[0031] In one embodiment, before returning to step S10, executing a different spin-drying policy based on a comparison result between the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment and the preset number of times, If the number of times that the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment is smaller than the preset number of times, proceed to step S10; and not performing spin-drying if the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment is not less than the preset number of times.

[0032] In this embodiment, the drum is controlled to operate at the second rotation speed and the damper is preheated to reduce the dynamic eccentricity increment, and the number of preheating times is set according to different specifications of the washing machine. If the number of times of operation of the above operation (i.e., the number of times the acquired dynamic eccentricity increment is greater than the preset dynamic eccentricity increment) exceeds the preset number, it is determined that high-speed spin-drying is not possible, and the drum is controlled to directly end the operation without spin-drying.

[0033] S40 controls the drum to operate at a third rotation speed to perform dewatering.

[0034] In one embodiment, if the dynamic eccentricity increment DP0 is equal to or less than the preset dynamic eccentricity increment DPZ, the current dynamic eccentricity increment has reached the standard and high-speed dehydration is possible, so the drum is controlled to operate at the third rotation speed.

[0035] In this embodiment, the first rotation speed < the second rotation speed < the third rotation speed. The first rotation speed varies depending on the washing machine of different specifications, and is optionally 60 r / min to 90 r / min. The second rotation speed varies depending on the washing machine of different specifications, and is optionally 150 r / min to 250 r / min. The third rotation speed varies depending on the spin command of different levels received by the washing machine, and is optionally 800 r / min, 1600 r / min, etc.
