Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes processing, and in particular relates to a control method of a washing machine and the washing machine. BACKGROUND

[0002] The washing machine is a household appliance that removes various pollutants attached to clothes through the friction of the water flow generated by stirring and rotating water, detergent and clothes and the impact on the washing. At present, washing machines have spread to millions of families, bringing many conveniences to people's lives. However, most washing machines do not have the function of automatically adding additives. Users need to manually determine the amount of additive each time they wash and care for clothes. The fuzzy and random addition of detergents or softeners, fragrance additives, bleaching agents, disinfectants and other care agents, as well as the addition each time, cannot provide detailed care for special or high-end clothes.

[0003] When performing a washing and caring program, especially a rinsing program, most washing machines will run according to the set rinsing program regardless of whether the user has added a softener. The rinsing program will not be adjusted due to the user manually adding too much or too little softener, and it will not recommend a rinsing program based on the type of clothes, such as large clothes like curtains, bed sheets and covers, which are difficult to rinse due to their large size and thickness, and small clothes like underwear, socks and baby clothes, which are easy to rinse due to their small size and thinness. This results in the execution of a non-differentiated rinsing program for large clothes, regular clothes and small clothes, which makes the softener unable to achieve the best care effect and affects the working ability of the washing machine.

[0004] Therefore, the present application is proposed. SUMMARY

[0055] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0057] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms'mounting', 'connection', 'connecting' should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0058] As shown in FIG. 1, the present application provides a control method of a washing machine, comprising the following steps: Figures 1 to 6 Step S1: obtaining a washing and caring program, and determining a theoretical adding amount of washing and caring additives;

[0059] Step S2: detecting an actual adding amount of washing and caring additives during execution of the washing and caring program;

[0060] Step S3: determining whether to adjust the washing and caring program based on the determined theoretical adding amount of washing and caring additives and the detected actual adding amount of washing and caring additives.

[0061]

[0062] ​The control method of the washing machine is based on the theoretical adding amount of the care additive and the actual adding amount of the care additive, and the washing machine is controlled to intelligently and accurately adjust the care program, so that better washing and care of clothes are achieved, the care program is optimized under the premise of ensuring the care effect, resource waste is avoided, the working performance of the washing machine is improved, and the user experience is enhanced.

[0063] Embodiment one

[0064] As shown in Figure 2 and Figure 3 , the control method of the washing machine provided in the embodiment of the application is a rinsing program, at least includes a water inlet stage, a rinsing stage and a water discharge stage, and specifically includes the following steps:

[0065] Step S100: obtaining the rinsing program, at least determining the weight of clothes and / or the water inlet amount corresponding to the current care, and determining the theoretical adding amount of the softener corresponding thereto;

[0066] Step S200: detecting the actual adding amount of the softener during the execution of the water inlet stage;

[0067] Step S300: based on the determined theoretical adding amount of the softener and the detected actual adding amount of the softener, determining whether to adjust the operating parameters of the water inlet stage and / or the rinsing stage.

[0068] The softener is a kind of chemical substance that can change the static and dynamic friction coefficients of fibers. When the static friction coefficient is changed, the hand touch has a smooth feeling and is easy to move on the fiber or fabric; when the dynamic friction coefficient is changed, the microstructure between fibers is easy to move mutually, that is, the fiber or fabric is easy to deform, and the clothes can be soft, fluffy and elastic.

[0069] In the embodiment, the operating parameters of the water inlet stage and / or the rinsing stage are adjusted based on the determined theoretical adding amount of the softener and the detected actual adding amount of the softener, so as to avoid that the user blurs or randomly adds the softener, and the adding amount of the softener is too much, so that a large amount of softener is left on the clothes; or the adding amount of the softener is too small, so that the clothes cannot be made more soft, fluffy and elastic.

[0070] As shown in Figure 3 , in step S200, the washing machine detects the actual adding amount of the softener, specifically including:

[0071] Step S201: stopping water supply after static water supply to a reference water level;

[0072] Step S202: stirring the rinsing water containing the softener, detecting the actual concentration of the softener in the rinsing water, and determining the actual adding amount of the softener.

[0073] In the embodiment, in the water feeding stage, after the water supply is stopped at the reference water level, the rinse water containing the softener is stirred to ensure that the softener and the water form a highly uniform mixed solution, so that the actual amount of the softener detected is more accurate.

[0074] As shown in FIG. 3, in step S300, the washing machine determines whether to adjust the operation parameters of the water feeding stage and / or the rinsing stage, specifically including: Figure 3

[0075] Step S301a: if the actual amount of the softener is equal to the theoretical amount, after the water supply is stopped after the water supply is stirred to the target water level, the rinsing stage is executed to enable the softener to be uniformly adsorbed on the clothes;

[0076] Step S301b: if the actual amount of the softener is less than the theoretical amount, after the water supply is stopped after the water supply is stirred to the target water level, the rinsing stage is executed to ensure that the actual concentration of the softener adsorbed on the clothes is close to the theoretical concentration, so that the effect of the softener is not reduced due to the actual amount being less than the theoretical amount of the softener determined;

[0077] Step S301c: if the actual amount of the softener is greater than the theoretical amount, after the water supply is stopped after the water supply is stirred to the target water level, the rinsing stage is executed to ensure that the actual concentration of the softener adsorbed on the clothes is close to the theoretical concentration, thereby reducing the residual amount of the softener.

[0078] As shown in FIG. 3, in step S300, the washing machine stops the water supply and executes the rinsing stage, specifically including: Figure 3

[0079] Step S302a: if the actual amount of the softener is equal to the theoretical amount, the set rinsing operation time is extended or maintained during the rinsing stage to enable the softener to better act on the clothes;

[0080] Step S302b: if the actual amount of the softener is less than the theoretical amount, the set rinsing operation time is extended during the rinsing stage to ensure that the softener can exert the best effect to make the clothes softer, fluffier, and more elastic;

[0081] Step S302c: if the actual amount of the softener is greater than the theoretical amount, the set rinsing operation time is shortened during the rinsing stage to reduce the residual amount of the softener on the clothes under the premise of ensuring the effect of the softener.

[0082] As shown in FIG. 3, in step S300, the washing machine stops the water supply and executes the rinsing stage, specifically including: Figure 3 ​​As shown, in the embodiment, in step S300, the washing machine stops water supply and performs the rinsing stage, and further comprises:

[0083] Step S303a: if the actual amount of softener added is equal to the theoretical amount of softener added, the set rotation speed is increased or maintained during the rinsing stage, so that the softener can be fully adsorbed on the clothes;

[0084] Step S303b: if the actual amount of softener added is less than the theoretical amount of softener added, the set rotation speed is increased during the rinsing stage, to ensure that the softener can be more fully adsorbed on the clothes, so that the clothes are softer, fluffier and more elastic;

[0085] Step S303c: if the actual amount of softener added is greater than the theoretical amount of softener added, the set rotation speed is reduced during the rinsing stage, to reduce the residual amount of softener on the clothes under the premise of ensuring the effect of the softener.

[0086] Through the control method of the washing machine, the rinsing program is adjusted based on the theoretical amount of softener added and the actual amount of softener added, so that the softener can achieve the best care effect, improve the working ability of the washing machine, and avoid the user manually adding too much softener, which causes a large amount of softener to remain on the clothes, or the user manually adding too little softener, which cannot make the clothes softer, fluffier and more elastic.

[0087] Embodiment Two

[0088] As shown in Figure 4 and Figure 5 The embodiment is a further limitation of the above-mentioned embodiment one, and before step S1, i.e., before the washing machine obtains the washing and care program and determines the theoretical amount of washing and care additive added, the following steps are further included:

[0089] Step S0: detecting whether softener is added;

[0090] Step S01: if no softener is added, performing the set rinsing program;

[0091] Step S02: if softener is added, recommending a rinsing program based on the type information of the clothes.

[0092] In the embodiment, the rinsing program is recommended based on the type information of the clothes, so that the softener can be better adsorbed on the clothes and exert the best effect, and the clothes with different type information are softer, fluffier and more elastic, improving the user's experience.

[0093] In this embodiment, the image acquisition device 300 acquires image information of the clothes in the washing machine, and determines type information of the clothes based on the image information of the clothes, the type information of the clothes including at least one of a size of the clothes, a thickness of the clothes, a wearing part of the clothes, and a material of the clothes.

[0094] As shown in the figure, Figure 5 In this embodiment, in step S02, the washing machine recommends a rinsing program based on the type information of the clothes, specifically including:

[0095] Step S02a: if the clothes are small clothes, maintaining or shortening the set rinsing running time, and / or maintaining or reducing the set rotating speed, to avoid too much softener remaining on the clothes, affecting the user experience;

[0096] Step S02b: if the clothes are regular clothes, maintaining or lengthening the set rinsing running time, and / or maintaining or increasing the set rotating speed, to ensure that the softener can play the best effect, making the clothes softer, fluffier and more elastic;

[0097] Step S02c: if the clothes are large clothes, lengthening the set rinsing running time, and / or increasing the set rotating speed, to make the softener more fully adsorbed on the clothes, so that the clothes are softer, fluffier and more elastic.

[0098] Through the above control method of the washing machine, the rinsing program is recommended based on the type information of the clothes, so that large clothes, regular clothes and small clothes execute differentiated rinsing programs, and the softener can achieve the best effect, making the clothes of different types more soft, fluffy and elastic, and improving the user experience.
