Description

Technical Field

[0001] This application relates to the field of control technology for washing machines, and more specifically, to a control method, device, medium, and system for a washing machine. Background Technology

[0002] Washing machines have become indispensable tools in people's lives, bringing great convenience. With the development of washing machine technology, the market has seen increasing diversification of washing machines, along with a growing number of functions and higher demands. Users want to maximize efficiency while ensuring effective cleaning and spin-drying. Currently, washing machine spin-drying functions are standardized and suitable for most loads. However, when the load is very light, the spin-drying success rate is low, and even when successful, it takes a long time, resulting in a poor user experience.

[0003] Currently, most washing machines have problems such as long spin-drying time and difficulty in spin-drying single items or small amounts of clothing. This is because all spin-drying processes use the same logic. However, when there is a very small load, it is difficult to spin-dry, resulting in a poor user experience.

[0004] The existing solution uses the same logic for washing machines to handle single items or small quantities of clothing, resulting in poor dehydration efficiency. Summary of the Invention

[0005] The main objective of this application is to provide a control method, device, medium, and system for a washing machine, so as to at least solve the problem that the existing solutions use the same logic for single or small quantities of clothing, resulting in poor dehydration efficiency.

[0006] To achieve the above objectives, according to one aspect of this application, a method for controlling a washing machine is provided, the method comprising:

[0007] Obtain the weight of the clothes to be dehydrated, get the current weight, and obtain the most recent water replenishment data, which includes the number of times the clothes were replenished and the time of the most recent water replenishment.

[0008] The current moisture content is determined based on the most recent water replenishment number and the current weight, or based on the most recent water replenishment time and the current weight.

[0017] Optionally, based on the current moisture content, the washing machine is controlled to spin-dry the clothes at different speeds, including:

[0018] Based on the current moisture content range, a target moisture content level is determined. The target moisture content level is either a first moisture content level or a second moisture content level. The first moisture content level indicates that the moisture content of the clothes to be dehydrated is higher than that of the clothes to be dehydrated, as indicated by the second moisture content level.

[0019] When the target moisture content is the first moisture content, the washing machine is controlled to spin-dry the clothes at a first rotation speed;

[0020] When the target moisture content is the second moisture content, the washing machine is controlled to spin-dry the clothes at a second rotation speed, where the first rotation speed is lower than the second rotation speed.

[0025] Obtain the eccentricity value of the clothes to be dehydrated at the current moment, and get the current eccentricity value;

[0026] If the current eccentricity value is less than the preset eccentricity value, the target moisture content level is determined based on the current moisture content range.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0042] As described in the background section, most washing machines currently suffer from problems such as long spin-drying time and difficulty in spin-drying single items or small quantities of clothing. This is because all spin-drying processes use the same logic. However, when there is a very small load, the special load is difficult to spin-dry, resulting in a poor user experience. In order to solve the problem of poor spin-drying efficiency caused by the use of the same logic for single items or small quantities of clothing in existing solutions, the embodiments of this application provide a control method, device, medium and system for a washing machine.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0044] This embodiment provides a method for controlling a washing machine. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0045] Figure 1 This is a schematic flowchart illustrating a washing machine control method according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:

[0046] Step S101: Obtain the weight of the clothes to be dehydrated, get the current weight, and obtain the most recent water replenishment data, which includes the number of times the clothes were replenished and the time of the most recent water replenishment.

[0047] Because some clothes are highly absorbent, the water level may drop during the wash cycle. In this case, rehydration is necessary. The most recent rehydration is recorded because it was least affected by other factors. Rehydration at other stages may have been completed earlier because the washing process was too long and the water was fully absorbed. No further rehydration is needed.

[0048] Step S102: Determine the current moisture content based on the most recent water replenishment time and the current weight, or determine the current moisture content based on the most recent water replenishment time and the current weight.

[0049] Step S102, which involves determining the current moisture content based on the most recent water replenishment count and the current weight, includes:

[0050] The current moisture content is determined by L = N × k, where L is the current moisture content, N is the number of the most recent water replenishment, and k is the target moisture content correction coefficient.

[0051] Specifically, the load can be divided into two types: one is highly absorbent, where the clothes are heavy before spin-drying due to their high absorbency during washing, and the load is also low, causing them to tend to be unevenly distributed to one side. In this case, spin-drying usually requires multiple attempts, takes a long time, and may even fail. The other type of load is less absorbent, where the clothes have low moisture content after washing due to their inherent low absorbency, resulting in less water needing to be removed. If the washing machine follows its normal cycle in this case, the spin-drying time can be very long, which is detrimental to the user experience. By taking into account the most recent water replenishment frequency and the target moisture content correction coefficient, the accuracy of moisture content calculation is improved.

[0052] In one embodiment of this application, before determining the current moisture content based on the most recent water replenishment count and the current weight, the method further includes:

[0053] The target weight class is determined to be the weight class corresponding to the current weight mentioned above;

[0054] By setting different weight grades, the target moisture content correction factor can be determined subsequently.

[0055] The target moisture content correction factor is determined to be the moisture content correction factor corresponding to the target weight grade and the most recent water replenishment time.

[0056] Specifically, the target moisture content correction factor is determined based on the mapping relationship table between the most recent water replenishment time and the current weight. That is, the value of the target moisture content correction factor is determined by taking into account both the most recent water replenishment time and the current weight, thereby improving the accuracy of the calculated moisture content.

[0057] Step S102, determining the current moisture content based on the most recent water replenishment time and the current weight, includes:

[0058] according to The current moisture content is determined as follows, where L is the current moisture content, T is the time of the most recent water replenishment, V is the water valve flow rate of the washing machine, and m is the current weight.

[0059] Specifically, by taking into account the most recent water replenishment time, the water valve flow rate of the washing machine, and the current weight, the accuracy of the calculated moisture content is improved.

[0060] The current moisture content is shown in Table 1. The third moisture content grade represents the moisture content level between the first and second moisture content grades. Table 1 shows the moisture content grades corresponding to different ranges of current weight and current moisture content.

[0061] Table 1

[0062]

[0063] Step S103: Based on the current moisture content, control the washing machine to spin-dry the clothes at different speeds.

[0064] In the above steps, the current moisture content is determined based on the most recent water replenishment time and the current weight, or based on the most recent water replenishment time and the current weight, thus achieving the purpose of accurate calculation of moisture content. Based on the current moisture content, the washing machine is controlled to spin-dry the clothes at different speeds, thereby improving the dehydration efficiency compared to the existing solutions and solving the problem that the existing solutions use the same logic for single or small quantities of clothes, resulting in poor dehydration efficiency.

[0065] In one embodiment of this application, according to the current moisture content, controlling the washing machine to spin-dry the clothes to be spun at different speeds includes:

[0066] Based on the current moisture content range, a target moisture content level is determined. The target moisture content level is either the first moisture content level or the second moisture content level. The first moisture content level indicates that the moisture content of the clothes to be dehydrated is higher than that of the clothes to be dehydrated, as indicated by the second moisture content level.

[0067] When the target moisture content is the first moisture content, the washing machine is controlled to spin-dry the clothes to be spun at the first speed.

[0068] When the target moisture content is the second moisture content, the washing machine is controlled to spin-dry the clothes to be spun at a second speed, where the first speed is lower than the second speed.

[0069] Specifically, for clothing with the first moisture content level, a pre-eccentricity test is performed before spin-drying. If the eccentricity value does not meet the drum-collision condition, a low-speed spin-drying process is performed first (i.e., the first rotation speed; the maximum spin-drying speed is calculated by the spin-drying formula, and if the obtained speed is greater than the maximum set speed, the maximum set speed is used). This low-speed spin-drying process can remove some water first. Since the clothing has a high moisture content and is more prone to water loss, this operation can remove most of the water, thus bringing the eccentricity closer to that of a normal load. Then, the normal spin-drying process is run. Although a short period of low-speed spin-drying is used beforehand, the water loss to a certain extent reduces the eccentricity, making it easier to increase the rotation speed for the normal spin-drying eccentricity test. This operation can save the time of repeatedly checking the eccentricity, thereby greatly improving the success rate and efficiency of spin-drying.

[0070] Pre-eccentricity detection:

[0071] Obtain the eccentricity value of the above-mentioned clothes to be dehydrated at the current moment, and get the current eccentricity value;

[0072] If the current eccentricity value is less than the preset eccentricity value, the target moisture content level is determined based on the current moisture content range.

[0073] When the current eccentricity value is greater than or equal to the preset eccentricity value, the washing machine is controlled to spin-dry the clothes to be spun at a third speed, wherein the third speed is less than the first speed and less than the second speed.

[0074] The third rotation speed can be the leveling speed during normal dehydration, used for buffering.

[0075] For garments with a second moisture content level, we can directly spin-dry them (i.e., at the second speed; the maximum spin speed is calculated using the spin-drying formula, and if the calculated speed is greater than the maximum set speed, then the maximum set speed will be used). Because these garments have fewer items and a low moisture content, it is difficult to remove water during the low-speed and medium-speed spin-drying stages. Although the pre-spin-drying time is short, the numerous steps will prolong the spin-drying time. Furthermore, due to the low moisture content, the amount of water removed is small or even almost zero, which actually increases the spin-drying time. If the garments are arranged properly, the eccentricity value is low, and the garments are less likely to collide with the drum. Even if the garments are placed to one side, resulting in a large eccentricity, this can be reduced by leveling them. At this point, directly attempting spin-drying will greatly shorten the spin-drying time and improve the user experience.

[0076] In one embodiment of this application, before controlling the washing machine to spin-dry the clothes to be spun at a first rotation speed, or controlling the washing machine to spin-dry the clothes to be spun at a second rotation speed, the method further includes:

[0077] According to the dehydration formula: Determine either the first rotational speed or the second rotational speed mentioned above;

[0078] Where n is either the first rotational speed or the second rotational speed mentioned above. The correction factor is Y, the current eccentricity value is C, the current number of judgments is M, and the target weight level is the weight level corresponding to the current weight.

[0079] Specifically, the current number of judgments refers to the number of times the first speed or the second speed mentioned above has been determined. The correction coefficient can be selected according to the model of the washing machine.

[0080] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the washing machine control method of this application will be described in detail below with reference to specific embodiments.

[0081] This embodiment relates to a specific control method for a washing machine, such as... Figure 2 As shown, it includes:

[0082] Get the weight of the clothes to be dehydrated, obtain the current weight, and get the most recent water replenishment data, which includes the number of times the clothes were replenished and the time of the most recent water replenishment.

[0083] Determine the target weight class as the weight class corresponding to the current weight; determine the target moisture content correction factor as the moisture content correction factor corresponding to the target weight class and the most recent water replenishment time;

[0084] The current moisture content is determined based on the most recent water replenishment frequency and the target moisture content correction factor.

[0085] Specifically, the current moisture content is determined according to L = N × k, where L is the current moisture content, N is the number of the most recent water replenishment, and k is the target moisture content correction coefficient.

[0086] Get the eccentricity value of the clothes to be dehydrated at the current moment, and obtain the current eccentricity value;

[0087] If the current eccentricity value is less than the preset eccentricity value, the target moisture content level is determined based on the current moisture content range.

[0088] When the current eccentricity value is greater than or equal to the preset eccentricity value, the washing machine is controlled to spin-dry the clothes at a third speed, wherein the third speed is less than the first speed and less than the second speed.

[0089] The preset eccentricity value can be set according to the inner diameter of the rotating drum;

[0090] If the current eccentricity value is less than the preset eccentricity value, the target moisture content level is determined according to the current moisture content range. The target moisture content level is either the first moisture content level or the second moisture content level. The first moisture content level represents a higher moisture content of the clothes to be dehydrated than the second moisture content level.

[0091] When the target moisture content is the first moisture content level, control the washing machine to spin the clothes at the first speed to spin dry;

[0092] When the target moisture content is the second moisture content level, the washing machine is controlled to spin the clothes at the second speed, while the first speed is lower than the second speed.

[0093] Specifically, before controlling the washing machine to spin-dry the clothes at a first speed or a second speed,

[0094] according to Determine the first speed or the second speed;

[0095] Where n is the first rotational speed or the second rotational speed. Y is the correction factor, C is the current eccentricity value, C is the current number of judgments, and M is the target weight class, which is the weight class corresponding to the current weight.
