[0002] With the continuous improvement of living standards, washing machines have entered thousands of households. Washing machines have become a necessity in our daily lives, but the water consumption of washing machines accounts for more than 50% of household water consumption, becoming the main source of household water. Whether from the perspective of natural resource conservation or from an economic perspective, improving the water efficiency of washing machines and reducing the water consumption of washing machines has become a necessary task in the production and development of washing machines.

[0003] In the prior art, the water intake of a washing machine is generally set only according to the weight of the laundry. However, if the user puts in wet clothes (for example, after being rubbed by hand or exposed to rain in advance) or fluffy clothes (for example, down jackets, summer quilts, etc.), it is inaccurate to set the water intake only by detecting the weight of the laundry, which will cause excessive or insufficient water intake, water intake errors, and poor washing effect.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0008] In a specific implementation of the control method of the above-mentioned washing equipment, the calculation formula for the descent height of the fixed weight block is: H1=nπd; wherein H1 is the descent height of the fixed weight block, n is the number of rotations of the support shaft, and d is the diameter of the rolling column.

[0009] In a specific implementation of the control method of the above-mentioned washing equipment, the calculation formula for the height of the object to be cleaned is: H2=H-H1; wherein H1 is the descending height of the fixed weight block, H2 is the height of the object to be cleaned, and H is the total height of the washing tub.

[0010] In a specific implementation of the control method of the above-mentioned washing equipment, the step of "determining the target water inlet height according to the first water inlet height and the second water inlet height" specifically includes: comparing the first water inlet height and the second water inlet height; when the first water inlet height is greater than the second water inlet height, the calculation formula of the target water inlet height is: L=L1-m(L1-L2); wherein L1 is the first water inlet height, L2 is the second water inlet height, L is the target water inlet height, and m is the correction coefficient.

[0011] In a specific implementation of the control method of the above-mentioned washing equipment, the step of "determining the target water inlet height according to the first water inlet height and the second water inlet height" further includes: when the first water inlet height is greater than the second water inlet height, the calculation formula of the target water inlet height is: L=L2-n(L1-L2); wherein L1 is the first water inlet height, L2 is the second water inlet height, L is the target water inlet height, and n is the correction coefficient.

[0027] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

In addition, ordinal numbers such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, it should be noted that in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in a different order.

[0031] Based on the technical problems raised in the background technology, the present invention provides a control method for a washing device, which aims to correct the amount of washing water by combining the weight and height of the objects to be washed, thereby improving the accuracy of judging the amount of washing water in different washing scenarios, reducing the problem of excessive water use during the washing process or incomplete washing and rinsing of the objects to be washed after washing, and improving the user experience.

[0032] The control method of the present invention is applicable to top-loading washing equipment, such as a pulsator washing machine, a top-loading shoe washing machine, etc. The specific implementation of the present invention is described below by taking the washing equipment as a pulsator washing machine as an example.

[0033] See first Figure 1 and Figure 2 ,in, Figure 1 is a schematic diagram of the structure of the pulsator washing machine of the present invention, Figure 2 Schematic diagram of the internal structure of the pulsator washing machine of the present invention. Figure 1 and Figure 2 As shown, the washing device includes a housing 1, a washing tub 2, a tub cover 3, a pressure cover 4 and a detection device 5. The washing tub 2 is arranged in the housing 1, the tub cover 3 is pivotally arranged at the opening of the washing tub 2, and the detection device 5 is arranged on the tub cover 3. The washing tub 2 is used to accommodate objects to be cleaned. When the user places the objects to be cleaned in the washing tub 2, the pressure cover 4 is placed in the washing tub 2 to prevent the objects to be cleaned from being thrown out during washing.

[0034] Then see Figure 3 and Figure 4 ,in, Figure 3 It is a schematic diagram of the structure of the detection device 5 of the present invention; Figure 4 FIG. 5 is a schematic diagram of the structure of the detection device 5 of the present invention when it is working. Figure 3 and Figure 4 As shown, the detection device 5 includes a support shaft 51, a connecting line 54, a driving motor 53, a rolling column 52 and a fixed weight block 55. The driving end of the driving motor 53 is connected to the supporting shaft 51, the supporting shaft 51 is rotatably arranged on the barrel cover 3, the rolling column 52 is fixedly arranged on the supporting shaft 51, one end of the connecting line 54 is wound around the rolling column 52, and the other end of the connecting line 54 is connected to the fixed weight block 55. The driving motor 53 adopts, for example, a stepping motor, a servo motor, etc. When the driving motor 53 is not working, the driving motor 53 releases the restriction on the supporting shaft 51, so that the supporting shaft 51 can rotate relative to the barrel cover 3, so that the fixed weight block 55 can be lowered in the washing barrel 2 under the action of gravity, so that the connecting line 54 on the rolling column 52 is lowered, so that the fixed weight block 55 can press down the objects to be washed in the washing barrel 2. When the fixed weight block 55 needs to rise back to its original position, the driving motor 53 locks the supporting shaft 51 and drives the supporting shaft 51 to rotate, thereby driving the rolling column 52 to rotate so that the connecting line 54 is wound around the rolling column 52 .

[0035] The weight of the fixed weight block 55 has a certain proportional relationship with the rated capacity of the washing machine. For example, the weight of the fixed weight block 55 is set to 10-20 N. It should be noted that the weight of the fixed weight block 55 is only an example, and those skilled in the art can adjust it as needed in actual operation, and the present invention does not impose any limitation on this.

[0036] It should also be noted that, although the above description is combined with "the connecting wire 54 is wound around the rolling column 52", this is not a limitation, and those skilled in the art can also omit the rolling column 52, and directly wind the connecting wire 54 around the support shaft 51, and realize the lowering or retracting of the connecting wire 54 by rotating the support shaft 51. In order to ensure that the fixed weight block 55 is stably raised and lowered in the washing tub 2, the rolling column 52 is preferably provided.

[0037] Furthermore, a detection device 56 is provided on the support shaft 51. Exemplarily, the detection device 56 is set as a displacement sensor. When the displacement sensor detects that the displacement does not change, it indicates that when the fixed weight block 55 is lowered to the object to be washed in the washing tub 2, the fixed weight block 55 no longer drops, and the rotating shaft does not rotate at this time. At the same time, the displacement sensor can also detect the number of rotations of the rotating shaft.

[0038] In the above structure, after the user places the objects to be cleaned in the washing tub 2, the user presses the fixed weight block 55 on the pressure cover 4 to evenly apply force to the objects to be cleaned in the washing tub 2, ensuring that the height of the objects to be cleaned in the washing tub 2 is basically level, so that the height of the objects to be cleaned obtained later is more accurate.

[0039] See below Figure 5 , which is a flow chart of the main steps of the control method of the washing equipment of the present invention. Figure 5 As shown, the control method of the present invention includes:

[0040] S1, obtaining the weight of the object to be cleaned in the washing tub 2;

[0041] S2, determining a first water inlet height into the washing tub 2 based on the weight of the object to be washed;

[0042] S3, obtaining the height of the object to be cleaned in the washing tub;

[0043] S4, determining a second water inlet height into the washing tub 2 based on the height of the object to be washed;

[0044] S5, determining a target water inlet height according to the first water inlet height and the second water inlet height;

[0045] S6, controlling the washing equipment to inlet water according to the target water inlet height.

[0046] In step S1 , the weight of the laundry to be washed can be obtained by fuzzy weighing or by setting a weight sensor on the washing tub 2 .

[0047] In step S2, a person skilled in the art will pre-store a mapping relationship between different weights of the laundry and the first water inlet height, and then match the corresponding water inlet height based on the actual weight of the laundry. For example, the weight of the laundry and the first water inlet height are positively correlated.

[0048] In step S3, the step of “obtaining the height of the object to be cleaned in the washing tub 2” specifically includes:

[0049] S31, when the fixed weight block 55 descends in the washing tub 2 and its weight is fully applied to the object to be washed, the number of rotations of the support shaft 51 is obtained, and the descending height of the fixed weight block 55 is calculated according to the number of rotations;

[0050] The calculation formula for the descending height of the fixed weight block 55 is:

[0051] H1=nπd;

[0052] Wherein, H1 is the descending height of the fixed weight block 55, n is the number of rotations of the support shaft 51, and d is the diameter of the rolling column 52;

[0053] S32, calculating the height of the object to be cleaned according to the descending height of the fixed weight block 55;

[0054] The calculation formula for the height of the object to be cleaned is:

[0055] H2=H-H1;

[0056] Wherein, H1 is the descending height of the fixed weight block 55 , H2 is the height of the object to be cleaned, and H is the total height of the washing tub 2 .

[0057] In step S31, the number of rotations of the support shaft 51 is obtained by setting a displacement sensor on the support shaft 51. When the displacement of the displacement sensor does not change, it indicates that when the fixed weight block 55 is lowered to the object to be washed in the washing tub 2, the fixed weight block 55 no longer drops, and the rotating shaft does not rotate at this time.

[0058] Furthermore, in step S31 , if the rolling post 52 is omitted, d is the diameter of the support shaft 51 .

[0059] In step S4, those skilled in the art will pre-store the mapping relationship between the different heights of the objects to be washed and the second water inlet height, and then match the corresponding water inlet height based on the height of the objects to be washed actually obtained.

[0060] In step S5, the step of “determining a target water inlet height according to the first water inlet height and the second water inlet height” specifically includes:

[0061] S51, comparing the first water inlet height with the second water inlet height;

[0062] S52, when the first water inlet height is greater than the second water inlet height, the calculation formula of the target water inlet height is:

[0063] L = L1-m(L1-L2);

[0064] S53, when the first water inlet height is greater than the second water inlet height, the calculation formula of the target water inlet height is:

[0065] L = L2-n(L1-L2);

[0066] When the first water inlet height is equal to the second water inlet height, the calculation formula for the target water inlet height is:

[0067] L = L1 = L2;

[0068] Among them, L1 is the first water inlet height, L2 is the second water inlet height, L is the target water inlet height, m ​​is the correction coefficient, and n is the correction coefficient.

[0069] In step S5, the present invention corrects the water inlet height according to the first water inlet height and the second water inlet height to obtain the target water inlet height, thereby improving the accuracy of the water inlet amount in different washing scenarios and reducing the problem of excessive or insufficient water use during the washing process. Specifically, when the user's to-be-washed items have been pre-washed, for example, there are stains on a certain part of the clothes and the clothes are rubbed by hand to make the clothes pre-soaked, or the clothes are soaked by rain, etc., if the first water inlet height is determined directly according to the weight of the clothes, then the water level of the first water inlet height will be larger than the water level required for actual washing, which will cause a waste of water resources. In this case, the second water inlet height is determined in combination with the height of the clothes, and the water inlet height is corrected. The first water inlet height is greater than the second water inlet height. Therefore, when the first water inlet height is greater than the second water inlet height, the target water inlet height L = L1-m (L1-L2), and illustratively, m = 2 / 3. When the items to be washed put in by the user are relatively fluffy items, such as down jackets, summer quilts, etc., such items take up a large area before being immersed in water, are relatively light in weight, and have good water absorption. If the first water inlet height is determined directly according to the weight of the clothes, then the water level of the first water inlet height will be smaller than the water level required for actual washing, which will cause insufficient water supply and poor washing and rinsing effects. In this case, the second water inlet height is determined in combination with the height of the clothes, and the water inlet height is corrected. The first water inlet height is less than the second water inlet height. Therefore, when the first water inlet height is less than the second water inlet height, the target water inlet height L = L1-n (L1-L2), and n = 1 / 3 for example. When the items to be washed put in by the user are other than the above two situations, at this time, the first water inlet height is equal to the second water inlet height, and the calculation formula of the target water inlet height is: L = L1 = L2.

[0070] It should be noted that the values ​​of the correction coefficient m and the correction coefficient n are only exemplary, and those skilled in the art may adjust them as needed in actual operation, and the present invention does not impose any limitation on this.

[0071] The control method of the present invention further includes:

[0072] Determine whether the user has set the water inlet height;

[0073] If the judgment result is "yes", the washing equipment is controlled to inlet water according to the set water inlet height.

[0074] If the judgment result is "No", execute step S2.

[0075] It should be noted that the step of “determining whether the user sets the water inlet height” may be performed before step S1 or after step S1 , and the present invention does not impose any limitation on this.

[0076] See below Figure 6 , a possible control process of the present invention is introduced. Figure 6 As shown, a possible complete process of the control method of the present invention is:
