Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular, relates to a control method for a washing device and the washing device. Background Art

[0002] "Washing equipment" refers to a general term for household appliances that have the function of washing clothes, such as washing machines, washer-dryers, etc. When washing clothes with a washing equipment, it is usually necessary to first put washing powder into the washing equipment, dissolve the put washing powder in water, and then use the dissolved washing powder to wash clothes.

[0003] In order to improve the treatment effect of washing powder on clothes, the current washing powder particles include stain removal ingredients, softener ingredients, bleaching ingredients, and fragrance ingredients, so that the washing powder has the functions of "stain removal, bleaching, softening, and fragrance enhancement".

[0004] However, after the washing powder is added to the washing water, all its components are dissolved and dispersed in the washing water at once, and the components interfere with each other and cannot fully exert their respective maximum effects;

[0005] For example: the detersive ingredient is mainly anionic surfactants, while the softening ingredient is mainly cationic surfactants. Once the detersive ingredient and the softening ingredient are dissolved in the washing water at one time, the detersive effect will be reduced due to the mutual interference between the anionic surfactants and the cationic surfactants.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The invention provides a control method for washing equipment, so as to achieve the purpose of dissolving different functional layers of washing powder step by step and fully exerting the efficiency of each component.

During or after the washing powder is added, the dissolution program is controlled to be executed at intervals to dissolve the different functional layers of the washing powder step by step.

[0011] Furthermore, the washing programs corresponding to the different functional layers of the washing powder are preset, and the control interval execution of the dissolution program includes:

[0012] The dissolution program is started, and after the outermost functional layer of the washing powder is dissolved, the dissolution program is controlled to stop and the washing program corresponding to the outermost functional layer is executed. After the washing program is finished, the dissolution program is controlled to be executed again to dissolve the second outer functional layer of the washing powder;

[0013] Preferably, the washing programs corresponding to different functional layers have different washing intensities and / or washing durations.

[0014] Furthermore, the washing device has an instant cavity for accommodating the washing powder to be added, and the dissolution procedure includes: controlling the water to be fed into the instant cavity to dissolve the washing powder, and during the process of adding the washing powder, controlling the water to be fed into the instant cavity at intervals, and adding the washing powder solution dissolved by each interval of water feeding separately.

[0015] Further, the dissolution procedure includes: controlling the heating of water in the instant dissolving chamber to dissolve the washing powder;

[0016] Preferably, the heating process and the water inlet process are controlled to start synchronously.

[0017] Furthermore, each functional layer of the washing powder particles is coated with a slow-release film, and the concentration of the component after the slow-release film outside the preset functional layer is completely dissolved is N 01 In the process of dissolving the detergent, the concentration N of the slow-release film component in the instant cavity is obtained, and the obtained concentration N is compared with the preset concentration N 01 The size of N≥N 01 , the dissolution program is controlled to be closed and the dissolved detergent solution is added.

[0018] Furthermore, the preset concentration N 02 , and N 02 >N 01 , when N ≥ N 01 When the dissolution program is controlled to be turned on again after being turned off for a preset time t1, the concentration N of the sustained-release film component in the quick-dissolving cavity is obtained, and the obtained component concentration N is compared with the preset component concentration N 02 The size of N≥N 02 , then the controlled dissolution program is closed.

[0019] Furthermore, the preset component concentration N 03 , and N 03 >N 02 , when N ≥ N 02 When the dissolution program is closed for a preset time t2, the dissolution program is turned on again, and the concentration N of the sustained-release film component in the quick-dissolving cavity is obtained, and the obtained component concentration N is compared with the preset component concentration N 03 The size of N≥N 03 , then the controlled dissolution program is closed;

[0020] Preferably, the preset time length t1>t2.

[0021] Furthermore, the washing device includes a barrel body for containing washing water, and the dissolution procedure includes controlling the heating of the washing water in the barrel body, and after the washing powder is put into the barrel body, controlling the interval heating of the washing water.

[0022] Preferably, the functional layer of the washing powder particles is coated with a slow-release film, and the concentration of the component after the slow-release film is completely dissolved is preset to be N 01 ', during the heating process, the concentration N of the slow-release film component in the barrel is obtained, and the obtained component concentration N is compared with the preset component concentration N 01 ', if N ≥ N 01 ', the control stops heating.

[0023] Furthermore, the washing device includes a barrel for containing washing water and a washing program and a rinsing program performed in sequence, and the functional layer of the washing powder particles is coated with a slow-release film.

In this way, the components of the different functional layers can be dispersed into the washing water step by step and act on the clothes respectively in different time periods. During the process of each component taking effect, it will not be disturbed by the undissolved functional layer, and the effect is good.

[0028] In the present invention, after the outermost functional layer of the washing powder is dissolved, the washing procedure corresponding to the outermost functional layer is performed, and the outermost functional layer will not be interfered by the undissolved core structure components during the functioning process, and can give full play to its effectiveness. After the outermost functional layer is completely dissolved, the core structure begins to dissolve, and after dissolving, it acts on the to-be-washed object treated by the outermost functional layer, and further treats the to-be-washed object. During the treatment process, since the outermost functional layer components have completely reacted with the to-be-washed object, the core structure components will not be interfered by the functional layer components when they act, and the effect is good.

[0029] The washing device of the present invention is controlled by the control method of the present invention. By adjusting the opening and closing of the dissolution program, different functional layers of the washing powder particles are dissolved step by step, so that the functions of various components of the washing powder are fully exerted and the treatment effect on clothes is good.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] "Washing equipment" refers to a general term for household appliances that have the function of washing clothes, such as washing machines, washer-dryers, etc. When washing clothes with a washing equipment, it is usually necessary to first put washing powder into the washing equipment, dissolve the put washing powder in water, and then use the dissolved washing powder to wash clothes.

[0047] like Figure 7 and Figure 8 As shown, the washing powder particles include different functional layers that are coated layer by layer. For example, the washing powder particles include a core structure 1 and a decontamination functional layer structure 2 located on the outer layer of the core structure 1; or, the washing powder particles include a core structure 1, a ball material 5 of a bleaching component functional layer structure located outside the core structure 1, and a decontamination functional layer structure 2 located outside the ball material 5 of the bleaching component functional layer structure.

[0048] The components of the decontamination functional layer structure 2 include: trichloroisocyanuric acid, sodium metasilicate, sodium bicarbonate, sodium hypochlorite, magnesium silicate, sodium dodecylbenzene sulfonate, sodium carbonate, sodium sulfate and other components.

[0049] The components of the core structure 1 include: one or more of quaternary ammonium salt, fatty alcohol polyoxyethylene ether, and fatty acid ester; the core structure 1 has the effect of making the fabric soft and fluffy, eliminating static electricity, and helping to restore the inherent smoothness, extension, and compression properties of the fiber. Alternatively, the components of the core structure 1 include sodium percarbonate; when the core structure 1 is dissolved in water, hydrogen peroxide is generated, and finally decomposed into water and oxygen, which has the effect of bleaching fabrics as an oxidant.

[0050] like Figures 1 to 6 As shown, the washing device includes a dissolution program for dissolving washing powder. When the dissolution program is turned on, the washing powder can be quickly dissolved under the action of the dissolution program. The control method of the washing device includes:

[0051] During the process of adding the washing powder, the dissolution program is controlled to be executed at intervals to dissolve different functional layers of the washing powder step by step. The different functional layers of the washing powder are dissolved step by step and added into the barrel of the washing device step by step.

[0052] Specifically, Figure 1 As shown, the control steps of the washing equipment include:

[0053] S1, start;

[0054] S2, start the dissolution program to dissolve the washing powder;

[0055] S3, closing the dissolution process;

[0056] S4, controlling the dissolving washing powder solution to be put into the barrel of the washing equipment;

[0057] S5, determine whether all the washing powder has been put in; if so, go to step S6, otherwise go to step S7;

[0058] Among them, different types of washing powder are preset with corresponding times N0 of dispensing according to the number of layers of their functional layers. During the dispensing process, the number of times N of dispensing is accumulated. If the accumulated number of times N of dispensing is greater than or equal to the number of times N0 of dispensing, it is determined that all washing powder has been dispensed. Otherwise, it is determined that the dispensing of washing powder has not been completed.

[0059] S6, controlling the dissolution program to close for a duration t, and returning to step S2; wherein the duration t corresponds to the detergent solution components dissolved in step S4, specifically, the duration t is the duration required for the dissolved detergent solution components to fully act on the clothes;

[0060] S7. End.

[0061] Alternatively, after the washing powder is added, the dissolution procedure is controlled to be executed at intervals to dissolve different functional layers of the washing powder step by step, that is, after the washing powder is added into the barrel of the washing device at one time, the different functional layers of the washing powder are dissolved step by step.

[0062] Specifically, Figure 2 As shown, the control steps of the washing equipment include:

[0063] S1, start;

[0064] S2, control the washing powder to be put into the barrel of the washing equipment;

[0065] S3, start the dissolution program to dissolve the washing powder;

[0066] S4, closing the dissolution process;

[0067] S5, determine whether the washing powder is completely dissolved, if so, go to step S6, otherwise go to step S7;

[0068] Among them, different types of washing powder are preset with corresponding dissolution times Q0 according to the number of layers of their functional layers. During the dispensing process, the number of times Q that have been dissolved is accumulated. If the accumulated number of times Q that have been dissolved is greater than or equal to the number of times Q0, it is determined that the washing powder is completely dissolved, otherwise, it is determined that the washing powder is not completely dissolved;

[0069] S6, controlling the dissolution program to close for a duration t, and returning to step S3; wherein the duration t corresponds to the detergent solution components dissolved in step S4, and specifically, the duration t is the duration required for the dissolved detergent solution components to fully act on the clothes;

[0070] S7. End.

[0071] In the present invention, after the dissolution program of the washing device is turned on, the washing powder can be dissolved quickly and efficiently, and the dissolution program is executed at controlled intervals so that different functional layers of the washing powder are dissolved step by step from the outer layer to the inner layer in sequence. In this way, the components of the different functional layers can be dispersed into the washing water step by step and act on the clothes respectively in different time periods. During the process of each component taking effect, it will not be disturbed by the undissolved functional layer, and the effect is good.

[0072] As an embodiment of the present invention, washing programs corresponding to different functional layers of washing powder are preset, and the control interval execution of the dissolution program includes: the dissolution program is started, and after the outermost functional layer of the washing powder is dissolved, the dissolution program is controlled to stop and the washing program corresponding to the outermost functional layer is executed, and after the washing program is finished, the dissolution program is controlled to be executed again to dissolve the second outermost functional layer of the washing powder.

[0073] Specifically, Figure 3 As shown, the control steps include:

[0074] S1, start;

[0075] S2, start the dissolution program to dissolve the washing powder;

[0076] S3, controlling the outermost functional layer of the washing powder (such as the decontamination functional layer structure 2) to dissolve; wherein the components of the decontamination functional layer structure 2 include: trichloroisocyanuric acid, sodium metasilicate, sodium bicarbonate, sodium hypochlorite, magnesium silicate, sodium dodecylbenzene sulfonate, sodium carbonate, sodium sulfate and other components;

[0077] S4, closing the dissolution process;

[0078] S5, controlling and executing the washing program corresponding to the outermost functional layer (e.g., decontamination functional layer structure 2);

[0079] S6, determine whether the washing powder is completely dissolved; if so, execute step S9, otherwise execute step S7;

[0080] S7, start the dissolution process to dissolve the secondary outer functional layer of the washing powder, such as: the inner core structure 1;

[0081] The components of the core structure 1 include: one or more of quaternary ammonium salt, fatty alcohol polyoxyethylene ether, and fatty acid ester; the core structure 1 has the effect of making the fabric soft, fluffy, and eliminating static electricity; helping to restore the inherent smoothness, extension, and compression properties of the fiber; or, the components of the core structure 1 include sodium percarbonate; when the core structure 1 is dissolved in water, hydrogen peroxide will be generated, and finally decomposed into water and oxygen, which has the effect of bleaching the fabric as an oxidant;

[0082] S8, controlling to execute the washing procedure corresponding to the secondary outer functional layer, and returning to step S6;

[0083] S9. End.

[0084] In this embodiment, after the outermost functional layer of the washing powder is dissolved, the washing procedure corresponding to the outermost functional layer is executed. During the process of the outermost functional layer taking effect, it will not be interfered by the undissolved components of the inner core structure 1, and can give full play to its effectiveness. After the outermost functional layer is dissolved, the inner core structure 1 begins to dissolve, and after dissolving, it acts on the laundry treated by the outermost functional layer, and further treats the laundry. During the treatment process, since the components of the outermost functional layer have completely reacted with the laundry, the components of the inner core structure 1 will not be interfered by the components of the functional layer when taking effect, and the effect is good.

[0085] As an implementation mode of this embodiment, the washing intensity, or the washing duration, or the washing intensity and the washing duration of the washing programs corresponding to different functional layers are different.

[0086] Specifically, during the washing process, it is detected whether there is a core structure 1 component in the washing water. If so, the washing intensity and washing time corresponding to the core structure component 1 are executed. Otherwise, the washing parameters corresponding to the functional layer structure components are controlled. The greater the speed and the rotation-stop ratio of the impeller or the barrel of the washing equipment, the greater the corresponding washing intensity.

[0087] For example, the core structure 1 is composed of a bleaching component, such as sodium percarbonate; the functional layer structure is composed of a decontamination component, and the washing intensity of the washing parameter corresponding to the decontamination component is controlled to be greater than the washing intensity of the washing parameter corresponding to the bleaching component.

[0088] When the decontamination component is dissolved in the washing water, the washing speed is V1; when the bleaching component is dissolved in the washing water, the washing speed is switched from V1 to V2, where V1>V2. Furthermore, the concentration of hydrogen peroxide in the washing water is detected. Once the concentration of hydrogen peroxide is detected to be greater than a preset value, it can be determined that the bleaching component is dissolved in the washing water.

[0089] In this way, under the action of a stronger water flow, the detergent ingredients can fully react with the clothes to ensure that the stubborn stains on the clothes are washed away; when the bleaching ingredients take effect, the washing intensity does not need to be too high, as long as the bleaching ingredients can contact the clothes to play their role.

[0090] As an embodiment of the present invention, the washing machine has an instant cavity for accommodating the washing powder to be put in. The user can put all the washing powder to be put in the instant cavity, so that the washing machine can automatically put the washing powder in the instant cavity into the barrel body.

[0091] The "dissolution procedure" in the present invention includes: a procedure for controlling water to flow into the instant cavity to dissolve the washing powder. In this way, during the process of adding the washing powder, water is controlled to flow into the instant cavity at intervals, and the washing powder solution dissolved by each interval of water flow is added separately.

[0092] In this embodiment, water is controlled to flow into the instant cavity, and the water entering the instant cavity will dissolve the washing powder, and the dissolution order is to dissolve from the outer layer of the washing powder particles to the inner layer layer by layer. After each layer is dissolved, the water flow into the instant cavity is stopped, and the washing powder solution that has been dissolved in the instant cavity is controlled to be put into the barrel body for washing clothes. This method realizes the precise control of the dissolution of different functional layers of washing powder, truly realizes the purpose of dissolving one component and putting one component, so that different components of washing powder will not interfere with each other.

[0093] As an implementation of this embodiment, the "dissolution program" also includes: controlling the water inlet into the heating instant cavity to dissolve the washing powder.

[0094] Specifically, a heating device is provided in the instant cavity of the washing machine. During or after the water is introduced into the instant cavity, the heating device is controlled to turn on and heat the water in the instant cavity so as to quickly dissolve the layer structure of the washing powder.

[0095] Alternatively, the washing device has a thermal water inlet pipe, which has a heating function and can heat the water flowing through the water inlet pipe. The thermal water inlet pipe is connected to the instant cavity and is used to supply hot water to the instant cavity to quickly dissolve the layer structure of the washing powder.

[0096] Preferably, the heating process and the water inlet process are controlled to start synchronously, so that the water flowing into the instant cavity can be heated accurately and quickly, so that the washing powder in the instant cavity dissolves quickly, thereby improving the delivery efficiency.

[0097] In this embodiment, the water inlet into the instant cavity is controlled and heated to improve the dissolution efficiency of the washing powder in the instant cavity, and the heating temperature and heating time can be adjusted according to the type of washing powder and the different functional layers of the washing powder particles.

[0098] As another embodiment of the present invention, each functional layer of the washing powder particles is coated with a slow-release film. Figure 7 As shown, the core structure 1 is coated with a sustained-release membrane structure 3; or, each functional layer structure has a sustained-release membrane structure 3 coating the functional layer structure.

[0099] For example: Figure 3 As shown, the core structure 1 is a softener component, and the core structure 1 is coated by the first slow-release membrane structure 31 to form a first coating body 4; the ball material 5 of the bleaching component functional layer structure is located outside the first coating body 4; or, the ball material 5 of the bleaching component functional layer structure is made into a slurry and coated on the outside of the first coating body 4; the first coating body 4 and the ball material 5 of the bleaching component functional layer structure are coated with the second slow-release membrane structure 32 to form a second coating body 6; finally, the decontamination functional layer structure 2 is coated on the outside of the second coating body 6.

[0100] When the washing powder is added to the washing water, the dissolution order of each component is: decontamination functional layer structure 2-second slow-release membrane structure 32-bleaching component functional layer structure-first slow-release membrane structure 31-core structure 1. In this way, the washing powder in this embodiment treats the clothes in the order of "decontamination-bleaching-softening", and the treated clothes not only have a good cleaning effect, but also become soft, free of static electricity, and less wrinkled.

[0101] In this embodiment, the functional layer structure first dissolves and acts on the clothes. After the functional layer structure is dissolved, the slow-release membrane structure protects the inner core structure 1 from immediately contacting the washing water. Instead, the inner core structure 1 starts to dissolve after the slow-release membrane structure is dissolved, thereby reserving sufficient time for the functional layer structure to process the clothes.

[0102] Furthermore, by coating the slow-release membrane structure 3 outside each functional layer structure, after the washing powder is added to the washing water, the functional layer structure located on the outer layer dissolves first and acts on the clothes. After the outer functional layer structure is completely dissolved, the inner functional layer structure is protected by the slow-release membrane structure 3 and will not contact the washing water immediately. Instead, the inner functional layer structure will start to dissolve after the slow-release membrane structure 3 is completely dissolved, thereby reserving sufficient time for the outer functional layer structure to process the clothes.

[0103] The slow-release membrane structure 3 can be a polyvinyl alcohol film. Polyvinyl alcohol is a water-soluble polymer characterized by good compactness, high crystallinity, strong adhesion, and a film made of it that is flexible and smooth, oil-resistant, solvent-resistant, abrasion-resistant, and has good gas barrier properties and good water solubility. The thickness of the slow-release membrane structure 3 in this embodiment can be adjusted according to the particle size of the washing powder particles.

[0104] The control method of this embodiment includes: presetting the concentration N of the component after the sustained-release film outside the functional layer is completely dissolved 01 In the process of dissolving the detergent, the concentration N of the slow-release film component in the instant cavity is obtained, and the obtained concentration N is compared with the preset concentration N 01 The size of N≥N 01 , the dissolution program is controlled to be closed and the dissolved detergent solution is added.

[0105] Specifically, a polyvinyl alcohol concentration detector is provided in the instant dissolving chamber of the washing equipment, and the polyvinyl alcohol concentration detector is controlled to be turned on to obtain the concentration N of the sustained-release film component in the instant dissolving chamber.

[0106] In this embodiment, if the obtained concentration N is greater than or equal to the preset concentration N 01 , it indicates that the sustained-release film outside the functional layer has been completely dissolved. Once the sustained-release film is dissolved, the functional layer components will immediately come into contact with water and quickly dissolve into the water. At this time, the dissolved detergent solution is controlled to be added so that the functional layer components can act on the clothes in the washing device to treat the clothes.

[0107] As another embodiment of the present invention, the preset concentration N 02 , and N 02 >N 01 When N ≥ N 01When the dissolution program is controlled to be turned on again after being turned off for a preset time t1, the concentration N of the sustained-release film component in the quick-dissolving cavity is obtained, and the obtained component concentration N is compared with the preset component concentration N 02 The size of N≥N 02 , the controlled dissolution program is closed.

[0108] In this embodiment, when the obtained concentration N is greater than or equal to the preset concentration N 01 , it indicates that the outermost functional layer structure of the washing powder particles has been completely dissolved. At this time, the dissolution program is controlled to be closed for the preset time t1, so that the components of the outermost functional layer can fully act on the clothes within the preset time t1 to treat the clothes.

[0109] Furthermore, after the dissolution program is closed for a preset time t1, it is opened again for dissolution. When the obtained concentration N is greater than or equal to the preset concentration N 02 , it indicates that the sub-outer functional layer structure of the washing powder particles has been completely dissolved. At this time, the dissolution program is controlled to be closed to prevent the dissolution program from continuing to dissolve the washing powder particles, causing the sub-outer functional layer of the washing powder particles to mix with the functional layer components within its sub-outer functional layer, thereby reducing the effect of each functional layer.

[0110] As another embodiment of the present invention, the preset component concentration N 03 , and N 03 >N 02 , when N ≥ N 02 When the dissolution program is closed for a preset time t2, the dissolution program is turned on again, and the concentration N of the sustained-release film component in the quick-dissolving cavity is obtained, and the obtained component concentration N is compared with the preset component concentration N 03 The size of N≥N 03 , the dissolution program is controlled to be closed; preferably, the preset time length t1>t2.

[0111] More specifically, if Figure 4 As shown, the control steps are as follows:

[0112] S1, start;

[0113] S2, preset concentration N 01 、N 02 、N 03 ; Preset duration t1, t2;

[0114] S3, start the dissolution program to dissolve the washing powder;

[0115] S4, obtaining the concentration N of the sustained-release film component in the quick-dissolving cavity;

[0116] S5. Determine whether the obtained concentration N is greater than or equal to the preset concentration N 01, if yes, go to step S6, otherwise return to step S3;

[0117] S6, closing the dissolution process;

[0118] S7, controlling the dissolving washing powder solution to be put into the barrel of the washing equipment;

[0119] S8, controlling the dissolution program to be turned on again after being turned off for a preset time t1;

[0120] S9, obtaining the concentration N of the sustained-release film component in the quick-dissolving cavity during the dissolution process;

[0121] S10, determine whether the obtained concentration N is greater than or equal to the preset concentration N 02 , if yes, go to step S11, otherwise return to step S9;

[0122] S11, controlling the dissolution program to be turned on again after being turned off for a preset time t2;

[0123] S12, obtaining the concentration N of the sustained-release film component in the quick-dissolving cavity during the dissolution process;

[0124] S13, determine whether the obtained concentration N is greater than or equal to the preset concentration N 03 , if yes, go to step S14, otherwise return to step S12;

[0125] S14, closing the dissolution process;

[0126] S15. End.

[0127] In this embodiment, each functional layer of the laundry detergent powder is coated with a slow-release membrane structure 3, and the outermost functional layer is a decontamination functional layer structure 2; the bleaching component functional layer structure is coated by the second slow-release membrane structure 32; and the core structure 1 is coated by the first slow-release membrane structure 31, and the core structure 1 is a softener component.

[0128] If the obtained concentration N is greater than or equal to the preset concentration N 01 , it indicates that the decontamination functional layer structure 2 has been dissolved. At this time, the control closes the dissolution program t1 and then restarts it. If the obtained concentration N is greater than or equal to the preset concentration N 02 , it indicates that the second sustained-release membrane structure 32 and the decontamination functional layer structure 2 coated therein have been dissolved. At this time, the control closes the dissolution procedure t2 and then restarts it. If the obtained concentration N is greater than or equal to the preset concentration N 03 , it indicates that the first sustained-release membrane structure 31 and the core structure 1 coated thereon have been dissolved, and at this time, the dissolution program is controlled to be closed.

[0129] In this embodiment, during the time when the dissolution program t1 is closed, the washing program corresponding to the decontamination functional layer is controlled to be executed; during the time when the dissolution program t2 is closed, the washing program corresponding to the bleaching component functional layer is controlled to be executed; after the first slow-release membrane structure 31 is dissolved, the washing program corresponding to the softener component is controlled to be executed.

[0130] The washing program corresponding to the decontamination functional layer has the largest proportion of running time to the total washing time, and the impeller speed and the turn-stop ratio are the largest; so that the decontamination components can fully act on the clothes to ensure that the stubborn stains on the clothes are washed away. The washing program corresponding to the bleaching component functional layer has a shorter proportion of running time to the total washing time, and the impeller speed and the turn-stop ratio are smaller; so that the bleaching components can penetrate into the clothes to bleach the clothes. The washing program corresponding to the softener component has the shortest proportion of running time to the total washing time, and the impeller speed and the turn-stop ratio are the smallest, so that the softener components can penetrate into the clothes to soften and remove static electricity. When the softener takes effect, the speed does not need to be too high to avoid tangling the clothes together and reducing its treatment effect.

[0131] As an embodiment of the present invention, the washing device includes a barrel for containing washing water, and the dissolution program includes controlling the heating of the washing water in the barrel, and after the washing powder is put into the barrel, controlling the interval heating of the washing water.

[0132] In this embodiment, the washing water is heated at intervals so that the washing powder can be quickly dissolved layer by layer from the outer layer to the inner layer during the heating process. In this embodiment, the purpose of gradually dissolving the washing powder particles in layers is achieved by controlling the interval heating of the washing water.

[0133] As an implementation of this embodiment, the functional layer of the washing powder particles is coated with a slow-release film, and the concentration of the component after the slow-release film is completely dissolved is preset to be N 01 ', during the heating process, the concentration N of the slow-release film component in the barrel is obtained, and the obtained component concentration N is compared with the preset component concentration N 01 ', if N ≥ N 01 ', the control stops heating.

[0134] Specifically, Figure 5 As shown, the control steps include:

[0135] S1, start;

[0136] S2, the concentration of the component after the preset sustained-release film is completely dissolved N 01 ';

[0137] S3, controlling the washing powder to be put into the barrel of the washing device;

[0138] S4, control heating of washing water to dissolve washing powder;

[0139] S5, obtaining the concentration N of the sustained-release film component in the barrel;

[0140] S6. Determine whether the obtained concentration N is greater than or equal to the preset concentration N 01 ', if yes, go to step S7, otherwise return to step S4;

[0141] S7, control to stop heating;

[0142] S8. End.

[0143] In this embodiment, if the obtained concentration N is greater than or equal to the preset concentration N 02 , it indicates that the sustained-release film outside the functional layer has been completely dissolved. Once the sustained-release film is dissolved, the functional layer components will immediately come into contact with water and quickly dissolve into the water. At this time, the heating is controlled to stop to prevent the other functional layers of the laundry detergent powder particles from continuing to dissolve and mixing with the already dissolved functional components, thereby reducing the effects of the components of each functional layer.

[0144] As another embodiment of the present invention, a washing device includes a barrel for containing washing water and a washing program and a rinsing program performed in sequence, and the functional layer of the washing powder particles is coated with a slow-release film.

[0145] The concentration of the component after the preset sustained-release film is completely dissolved N 02 ', during the washing process, the concentration N of the slow-release film component in the barrel is obtained, and the obtained concentration N is compared with the preset concentration N 02 ', if N ≥ N 02 ', then the washing program will be started after the set washing time.

[0146] Specifically, Figure 6 As shown, the control steps are as follows:

[0147] S1, start washing;

[0148] S2, the concentration of the components after the preset sustained-release film is completely dissolved N 02 ';

[0149] S3, controlling the interval to execute the dissolution program to dissolve the washing powder;

[0150] S4, obtaining the concentration N of the sustained-release film component in the barrel;

[0151] S5. Determine whether the obtained concentration N is greater than or equal to the preset concentration N 02 ', if yes, go to step S6, otherwise return to step S3;

[0152] S6. After controlling the set washing time, enter the rinsing program; the set time can be adjusted according to actual conditions, for example, 10 minutes.

[0153] In this embodiment, if the obtained concentration N is greater than or equal to the preset concentration N 02 ', it indicates that the detergent has been completely dissolved. At this time, the control continues to wash for a set time and directly enters the rinsing program, which simplifies the control process of the washing equipment.

[0154] As another embodiment of the present invention, a method for preparing a washing powder as described in any one of the above technical solutions is provided, which specifically comprises:

[0155] S1, preparing functional layer slurry;

[0156] S2, placing the core structure 1 in a molding device;

[0157] S3, injecting the prepared functional layer slurry into a molding device, drying, and cooling to obtain washing powder particles.

[0158] In the present invention, the functional layer slurry is injected into the molding equipment so that the functional layer structure can be coated on the outside of the core structure 1, thereby preparing a washing powder particle having a layered core structure and a functional layer structure; the functional layer structure of the powder particle located on the outer layer is dissolved first, and the core structure is dissolved later, so that different components act on the clothes in sequence according to the dissolution order, and the clothes are treated in steps.

[0159] As an embodiment of the present invention, a method for preparing washing powder comprises:

[0160] S1, preparing functional layer slurry;

[0161] S2, firstly coating the sustained-release membrane structure 3 outside the inner core structure 1;

[0162] S3, placing the core structure 1 coated with the sustained-release membrane structure 3 in a molding device;

[0163] S4, injecting the prepared functional layer slurry into a molding device;

[0164] S5, drying and cooling to obtain washing powder particles.

[0165] Preferably, the sustained-release membrane structure is a polyvinyl alcohol film.

[0166] In step S2 of this embodiment, coating the slow-release film structure 3 on the outer surface of the core structure 1 includes: immersing the component particles constituting the core structure into a polyvinyl alcohol aqueous solution, drying, and cooling, to obtain the core structure 1 coated with a polyvinyl alcohol film. For example: immersing a hemispherical cationic softener into a polyvinyl alcohol aqueous solution, and then drying and cooling to form a polyvinyl alcohol film to wrap the softener core structure 1.

[0167] The preparation method of this embodiment can be used to prepare washing powder particles having a slow-release membrane structure 3 between the core structure 1 and the functional layer structure. When the washing powder is added to the washing water, the functional layer structure first dissolves and acts on the clothes. After the functional layer structure is dissolved, the slow-release membrane structure 3 protects the core structure 1 from immediately contacting the washing water. Instead, the core structure 1 starts to dissolve after the slow-release membrane structure 3 is dissolved, thereby reserving sufficient time for the functional layer structure to process the clothes.

[0168] As another embodiment of the present invention, the core structure of the softener component is coated with a bleaching component functional layer structure and a decontamination component functional layer structure in sequence from the inside to the outside, and the preparation steps include:

[0169] S1, coating the slow-release membrane structure 3 on the outer surface of the core structure 1 of the softener component to form a first coating body 4;

[0170] S2, placing the first coating body 4 and the bleaching component functional layer structure ball material 5 into a molding device, and heat-sealing and coating them with the slow-release film structure 3 to form a second coating body 6;

[0171] S3, preparing a decontamination component functional layer structure slurry;

[0172] S4, placing the second coating body 6 in a molding device;

[0173] S5, injecting the prepared decontamination component functional layer structure slurry into a molding device;

[0174] S6, drying;

[0175] S7, cooling to obtain washing powder particles.

[0176] The powder particles prepared by the preparation method of this embodiment are, from the outer layer to the inner layer, the following: decontamination functional layer structure 2 - the second slow-release membrane structure 32 - the bleaching component functional layer structure - the first slow-release membrane structure 31 - the inner core structure 1. In this way, the washing powder in this embodiment will treat the clothes in the order of "decontamination-bleaching-softening". The treated clothes not only have a good cleaning effect, but also become soft after washing, do not have static electricity, and have fewer wrinkles.

[0177] As an implementation mode of this embodiment, preparing a decontamination component functional layer structural slurry includes: weighing trichloroisocyanuric acid, sodium metasilicate, sodium bicarbonate, sodium hypochlorite, and magnesium silicate, putting them into 40-50°C water, stirring to dissolve, raising the temperature to 60-65°C, and then adding sodium dodecylbenzene sulfonate and sodium carbonate to dissolve, adding sodium sulfate after dissolution, filtering, degassing, and aging to obtain the product.

[0178] Specifically, in the present invention, 5-8 parts of trichloroisocyanuric acid, 10-15 parts of sodium metasilicate, 4-6 parts of sodium bicarbonate, 2-5 parts of sodium hypochlorite, and 10-11 parts of magnesium silicate are weighed in proportion, put into warm water at 40-50° C., and stirred with a slurry mixer; after stirring and dissolving, the temperature is raised to 60-65° C., and 20-30 parts of sodium dodecylbenzene sulfonate and 20-25 parts of sodium carbonate are added and dissolved; after dissolution, 20-30 parts of sodium sulfate are added, followed by filtering and degassing, and then aging for 30-40 minutes to obtain a decontamination component functional layer structure slurry.

[0179] The functional layer structure slurry of the decontamination component is injected into a spherical molding device equipped with sodium percarbonate and softener wrapped with a polyvinyl alcohol film, dried at 110-120°C to remove excess moisture, and finally cooled. Finally, 5-15 parts of protease and lipase and 1-2 parts of fragrance are sprayed on the surface to obtain laundry detergent powder particles.

[0180] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0181] The washing device of the present invention is controlled by the control method of the present invention. By adjusting the opening and closing of the dissolution program, different functional layers of the washing powder particles are dissolved step by step, so that the functions of various components of the washing powder are fully exerted and the treatment effect on clothes is good.

[0182] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
