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] With the rapid development of technology and the continuous improvement of people's living standards, as well as the popularization and widespread use of detergents, many models of washing machines on the market have added automatic dispensing devices to meet the needs of users. The automatic dispensing device can automatically dispense detergents to avoid repeated work for users. There are many types of detergents on the market, and different types of detergents have different concentrations and ingredients. Different concentrations and ingredients of detergents mean that the amount of detergent used for the same weight of clothes is also different.

[0003] The automatic dispensing device currently added to the washing machine cannot accurately control the amount of detergent to be dispensed for all types of detergents, so the washing machine generally sets a standard dispensing value, and all detergent usage is dispensed according to this standard value. However, when the concentration of the detergent used by the user is significantly different from the standard value stored in the washing machine, the problem of over-dispensing or under-dispensing will occur during the washing process. When too much is dispensed, it will cause the problem of difficult to rinse the clothes after washing, wasting detergent and rinsing water; and when insufficient detergent is dispensed, it will directly lead to unclean clothes, causing user complaints.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method and a washing device. After determining that the selected target detergent type is within the preset detergent type range, the amount of detergent to be added is determined by using the clothing information and the target detergent type selected by the user, thereby avoiding the waste of detergent and rinse water caused by excessive detergent addition and the reduced washing effect of clothes caused by insufficient detergent addition, thereby achieving the purpose of being able to achieve precise control of the amount of detergent added and thus improving the user experience.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] The present invention provides a control method for a washing device.

[0008] Get the target detergent type selected by the user;

[0009] determining whether the selected target detergent type is within a preset detergent type range;

[0010] If so, the clothing information is obtained, and the amount of detergent to be added is determined according to the clothing information and the selected target detergent type.

[0011] Further, detergent type includes brand, ingredients, and concentration;

[0012] First, determine whether the selected target detergent brand is within the preset detergent brand range;

[0013] Then, it is determined whether the selected target detergent composition and concentration are respectively within the preset detergent composition range and the preset detergent concentration range contained in the same detergent brand.

[0014] Further, if the selected target detergent brand is within the preset detergent brand range; and,

[0015] The selected target detergent composition and concentration are respectively within a preset detergent composition range and a preset detergent concentration range contained in the same detergent brand;

[0016] The selected target detergent type is within the preset detergent type range.

[0017] Further, if the selected target detergent brand is not within the preset detergent brand range; or,

[0018] The selected target detergent ingredient is not within the range of preset detergent ingredients contained in the same detergent brand; or,

[0019] The selected target detergent concentration is not within the preset detergent range included in the same detergent brand;

[0020] Then the selected target detergent type is not within the preset detergent type range.

[0021] Further, if it is determined that the selected target detergent type is not within the preset detergent type range;

[0022] The washing machine prompts the user to change the detergent brand and recommends a detergent brand to the user; or,

[0023] Prompt the user to change the composition and / or concentration of the detergent, and recommend the composition and / or concentration of the detergent to the user if the detergent brand remains unchanged.

[0024] Furthermore, a comparison table of detergent type, clothing information and detergent dosage is preset in the washing device, and the detergent dosage is obtained by looking up the table according to the detergent type and clothing information;

[0025] The washing machine obtains the detergent brand by photographing the brand icon carried by the detergent and obtains the detergent concentration and ingredients by scanning the QR code or barcode carried by the detergent, thereby obtaining the detergent type.

[0026] Further, according to the clothing information and the selected target washing type, the determined detergent dosage is the calculated detergent dosage;

[0027] When adjusting the calculated dosage of detergent corresponding to the selected target detergent type, the calculated dosage of detergent corresponding to other detergent types with different concentrations under the same clothing information is adjusted.

[0028] Further, if the calculated amount of detergent L1 corresponding to the selected target detergent type is adjusted to L1'=L1(1+a);

[0029] The revision coefficient K is called according to the washing concentration, and the calculated amount L2 of the corresponding detergent in other detergent types is adjusted to L2'=L2(1+a)K1, the calculated amount L3 is adjusted to L3'=L3(1+a)K2, ... the calculated amount Ln is adjusted to Ln'=Ln(1+a)K(n-1); a is greater than -1 and less than 1; the revision coefficient K is greater than 0 and less than 1.

[0030] Furthermore, different detergent concentrations have different corresponding revision coefficients K, and the higher the detergent concentration, the smaller the corresponding revision coefficient K.

[0031] The present invention also provides a washing device, and a control method for the washing device provided by the above technical solution.

[0032] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] By determining that the selected target detergent type is within the preset detergent type range, the amount of detergent added is determined using the clothing information and the target detergent type selected by the user. This can avoid wasting detergent and rinse water when too much detergent is added, and reducing the washing effect of clothes when insufficient detergent is added. This can achieve precise control of the amount of detergent added, thereby improving the user experience.

[0034] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] 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.

[0041] like Figure 1 As shown, the present invention provides a control method for a washing device.

[0042] Obtain the target detergent type selected by the user; determine whether the selected target detergent type is within a preset detergent type range; if so, obtain clothing information, and determine the amount of detergent to be added based on the clothing information and the selected target detergent type.

[0043] In an embodiment of the present invention, after determining that the selected target detergent type is within a preset detergent type range, the amount of detergent added is determined using clothing information and the target detergent type selected by the user. This can avoid wasting detergent and rinsing water when too much detergent is added, and reducing the washing effect of clothes when the amount of detergent added is insufficient. This can achieve precise control of the amount of detergent added, thereby improving the user experience.

[0044] The information of the clothes includes the weight of the clothes and / or the material of the clothes. The washing machine is provided with a clothes sensor for weighing the weight of the clothes and a material sensor for detecting the material of the clothes;

[0045] The washing machine is preset with a comparison table of detergent type, clothing information and detergent dosage. Combined with the comparison table, the detergent dosage can be calculated according to the material and / or weight of the clothing and the selected target detergent type;

[0046] For clothes of the same weight, the amount of detergent to be added varies depending on the material of the clothes. For example, clothes made of different materials have different water absorption properties. For materials with good water absorption properties, the amount of detergent to be added can be relatively less.

[0047] For clothes of the same material, different amounts of detergent need to be added when using the same type of detergent depending on the weight of the clothes. For example, clothes of different weights require more detergent for washing if they are heavier.

[0048] The washing device is provided with a control unit, which receives data detected by the weight sensor and / or the material sensor and calculates the amount of detergent to be added according to a comparison table.

[0049] The washing device is a washing machine, which may be a drum washing machine or a pulsator washing machine; when the washing machine is a drum washing machine, the drum washing machine comprises a casing, an outer drum arranged in the casing, and an inner drum rotatably arranged in the outer drum; when washing clothes, the outer drum is a water drum, and the inner drum is used to place clothes, or, when washing clothes, the inner drum is a water drum, and the inner drum is used to place clothes.

[0050] The drum washing machine is provided with a dispensing device, through which detergent is dispensed into the drum washing machine. The dispensing device is used as an external dispensing device, which is arranged outside the casing and connected to the water drum through a pipe running through the casing. Alternatively, the dispensing device is used as a built-in dispensing device, which is arranged in the casing and connected to the water drum through a pipe arranged in the casing.

[0051] Furthermore, the detergent equipment is provided with a camera scanning device. The detergent package carries a brand icon to obtain the detergent brand and scans the QR code or barcode carried on the detergent package to obtain the detergent concentration and ingredients, thereby obtaining the detergent type, that is, the detergent type is affected by the brand, concentration and ingredients. The concentration of the detergent is reflected in the concentration of the active substance. The greater the concentration of the active substance, the less the amount of detergent that can be put in. The detergent ingredients are reflected in the composition of the active substance. The activity of active substances of different ingredients is different. The stronger the activity of the active substance, the stronger the decontamination ability, and the less the amount of detergent that can be put in.

[0052] The control unit obtains the imaging information and scanning information of the imaging scanning device, and determines the brand, concentration and composition of the detergent according to the imaging information and scanning information.

[0053] like Figure 1 As shown, in the embodiment of the present invention, the detergent type includes brand, ingredients and concentration;

[0054] First, determine whether the selected target detergent brand is within the preset detergent brand range;

[0055] Then, it is determined whether the selected target detergent composition and concentration are respectively within the preset detergent composition range and the preset detergent concentration range contained in the same detergent brand.

[0056] In the embodiment of the present invention, there are multiple brands of detergents, and the concentrations, ingredients, etc. of detergents of different brands may be different. The same brand of detergents may also have multiple types, and their concentrations, ingredients, etc. are different. For example, under the same brand, there are concentrated detergents and non-concentrated detergents due to different concentrations; for another example, there are active detergents and inactive detergents due to ingredients with active enzymes and ingredients without active enzymes. Therefore, when determining whether the selected target detergent type is within the preset washing type range, the detergent brand is determined first, and then the ingredients and concentration are determined, which can reduce the time for selecting the target detergent type;

[0057] There are multiple detergent brands stored in the user's home. The user selects a detergent type that matches the material and / or weight of the clothes from the multiple stored detergent types. The selected detergent brand, concentration and ingredients are determined. The camera scanning device captures the brand icon of the selected detergent and scans the QR code or barcode of the selected detergent to determine the target detergent type selected by the user.

[0058] The type of detergent selected by the user must take both the material and the weight into consideration, so that the amount of detergent stored can meet the weight of the clothes.

[0059] The washing machine is preset with a detergent type range, specifically including a preset detergent brand range, a preset detergent component range contained in the same detergent brand, and a preset detergent concentration range. Only after determining that the target detergent brand is within the preset detergent brand range can it be determined whether the target detergent component and concentration are respectively within the preset detergent component range and the preset detergent concentration range contained in the same detergent brand. Determining whether the target detergent type is within the preset detergent type range in the above order can reduce the time for selecting the target detergent type.

[0060] Further, if the selected target detergent brand is within the preset detergent brand range; and,

[0061] The selected target detergent composition and concentration are respectively within a preset detergent composition range and a preset detergent concentration range contained in the same detergent brand;

[0062] The selected target detergent type is within the preset detergent type range.

[0063] If the selected target detergent brand is not within the preset detergent brand range; or

[0064] The selected target detergent ingredient is not within the range of preset detergent ingredients contained in the same detergent brand; or,

[0065] The selected target detergent concentration is not within the preset detergent range included in the same detergent brand;

[0066] Then the selected target detergent type is not within the preset detergent type range.

[0067] For example, the user's home has brand A detergent and brand B detergent stored. The user selects a target detergent type of brand A, concentration B, and component C that matches the material and / or weight of the clothes to wash the clothes according to the material and / or weight of the clothes.

[0068] After the washing machine obtains the target detergent type selected by the user by using the camera scanning device, it first determines whether brand A is within the preset brand range. If so, it then determines whether the concentration of B is within the preset concentration range included in brand A. If so, it then determines whether component C is within the preset component range included in brand A. If so, it determines that the selected target detergent type is within the preset detergent type range.

[0069] For another example, a touch icon of a brand appears on the mobile phone APP or on the touch screen of the washing machine. When the user clicks on the touch icon of the brand, a preset detergent brand range appears on the mobile phone APP or on the touch screen of the washing machine. For example, the preset detergent brand range includes brand A, brand B, and brand C. Each brand is represented by a touch icon on the mobile phone APP or on the touch screen of the washing machine. Since the preset detergent brand range includes brand A, the selected target detergent brand is within the preset detergent brand range. The user clicks on the touch icon of brand A, so that the washing machine can obtain the target detergent brand selected by the user.

[0070] After obtaining the target detergent brand selected by the user, the preset detergent concentration range and preset detergent ingredient range included in brand A detergent will appear on the mobile phone APP or the touch screen of the washing machine. For example, the preset detergent concentration range includes A concentration, B concentration and C concentration, and the preset detergent ingredient range includes ingredient A, ingredient B and ingredient C. Each concentration is represented by a touch icon on the mobile phone APP or the touch screen of the washing machine, and each ingredient is represented by a touch icon on the mobile phone APP or the touch screen of the washing machine. Since the preset detergent concentration range includes B concentration and the preset detergent ingredient range includes ingredient C, the selected target detergent concentration is within the preset detergent concentration range, and the selected target detergent ingredient is within the preset detergent ingredient range.

[0071] After the washing machine obtains the target detergent type selected by the user by using the camera scanning device, it first determines whether brand A is within the preset brand range. If not, it is not necessary to determine whether the concentration of B and the component of C are respectively within the preset concentration range and the preset component range included in brand A, and it is determined that the selected target detergent type is not within the preset detergent type range;

[0072] After the washing machine uses the camera scanning device to obtain the target detergent type selected by the user, if yes, it then determines whether the concentration of B is within the preset concentration range included in brand A. If not, there is no need to determine whether component C is within the preset component range included in brand A, and it is determined that the selected target detergent type is not within the preset detergent type range.

[0073] like Figure 1 As shown, in an embodiment of the present invention, if it is determined that the selected target detergent type is not within the preset detergent type range;

[0074] The washing machine prompts the user to change the detergent brand and recommends a detergent brand to the user; or,

[0075] Prompt the user to change the composition and / or concentration of the detergent, and recommend the composition and / or concentration of the detergent to the user if the detergent brand remains unchanged.

[0076] In an embodiment of the present invention, the washing machine prompts the user to change the detergent brand, the composition or the concentration of the detergent through an alarm sound or an alarm light, so that the user can change the detergent type in time;

[0077] The washing machine recommends detergent brands to users based on the detected clothing material; for example, if the clothing material is silk and the user's brand A is not within the preset brand range, the washing machine recommends a brand that matches the silk material, namely brand B;

[0078] After the washing machine recommends a detergent brand to the user, the user checks whether the recommended detergent brand is among all detergent brands stored in the home based on the recommended detergent brand. If the recommended detergent brand is stored in the home, the user selects the recommended detergent brand on the mobile phone APP or the touch screen of the washing machine. If the recommended detergent brand is not stored in the home, the user can select a brand similar to the recommended detergent brand from all stored detergent brands. The similarity of detergent brands lies mainly in the similar ingredients, and they can wash clothes of similar materials. Alternatively, the user can obtain the recommended detergent type through other channels, such as purchase, borrowing, etc.

[0079] Regarding the composition and / or concentration of detergents recommended to users, for example, brand A detergent includes a pre-stored first type and a pre-stored second type, the first type has a1 component and b1 concentration, and the second type has a2 component and b2 concentration. If the composition and concentration of the target detergent are a3 component and b1 concentration respectively, the composition and concentration in the pre-stored first type and the composition and concentration in the pre-stored second type are not the composition and concentration in the target detergent type, since the a1 component is suitable for most clothes, the user may be recommended to select the pre-stored first type so that it can be adaptively matched with the material of the clothes;

[0080] In addition, other detergent types contained in other brands can also be recommended to users. For example, detergent brand A and detergent brand B may only have different brand names, and both have the same ingredient a that matches the material of clothing. In this case, the detergent type with ingredient a in detergent brand B can be recommended to users.

[0081] Furthermore, if the user selects the recommended detergent type, the amount of detergent to be added is determined based on the clothing information and the recommended detergent type, and the washing parameters of the washing device are adaptively adjusted.

[0082] The washing parameters may be washing time and washing speed, and the washing effect on the clothes may be increased by extending the washing time and / or increasing the washing speed;

[0083] By adjusting the washing parameters of the washing equipment, the washing effect of the detergent on the clothes can be kept unchanged, avoiding the reduction of the washing effect on the clothes due to the change of the washing type;

[0084] For example, under the same brand, the target detergent type has a composition a and a concentration b, and the recommended detergent type has a composition a1 and a concentration b. The target detergent type has a composition a1 specifically for washing cotton clothes, and the recommended detergent type has a composition a1 that is suitable for clothes of all materials. After selecting the recommended detergent type, since the recommended detergent type is not specifically for washing cotton clothes, the washing effect of the clothes may be reduced. Therefore, in order to keep the detergent effect unchanged, the washing speed of the washing equipment can be increased.

[0085] In addition, if the user does not select the recommended detergent type, the user reselects the target detergent type.

[0086] In the embodiment of the present invention, the detergent dosage determined according to the laundry information and the selected target washing type is the calculated detergent dosage;

[0087] When adjusting the calculated dosage of detergent corresponding to the selected target detergent type, the calculated dosage of detergent corresponding to other detergent types with different concentrations under the same clothing information is adjusted.

[0088] In the embodiment of the present invention, when the user adjusts the calculated amount of detergent corresponding to the target detergent type according to his or her own habits or the degree of dirtiness of the detected clothes, the user can adjust it manually, or the washing machine can adjust it automatically, and wait for the user to confirm. By adjusting the calculated amount of detergent, it is possible to avoid the situation where the detergent is wasted due to excessive detergent and the laundry washing effect is poor due to insufficient detergent.

[0089] The calculated amounts of detergent corresponding to other detergent types with different concentrations under the same clothing information are adjusted as the calculated amount of detergent corresponding to the target detergent type is adjusted, and the calculated amounts of detergent corresponding to all detergent types after the adjustment are updated in the comparison table. When clothes with the same clothing information are washed again, the detergent amount is obtained according to the updated comparison table, so that the washing effect of the clothes can remain unchanged.

[0090] Further, if the calculated amount of detergent L1 corresponding to the selected target detergent type is adjusted to L1'=L1(1+a);

[0091] Then, the correction coefficient K is called according to the washing concentration, and the calculated amount of detergent L2 corresponding to each of the other detergent types is adjusted to L2'=L2(1+a)K1, and the calculated amount of detergent L3 is adjusted to L3'=L3(1+a)

[0092] K2, ... the calculated delivery amount Ln is adjusted to Ln'=Ln(1+a)K(n-1); a is greater than -1 and less than 1; the revision coefficient K is greater than 0 and less than 1.

[0093] It should be noted that the above adjustment of the amount of detergent applied is applicable not only to detergents of the same brand, but also to detergents of different brands;

[0094] For example, the detergent types under brand A are represented by A1, A2, A3, etc., and the detergent types under brand B are represented by B1, B2, B3, etc., and the concentration of each detergent type is different;

[0095] The calculated amount of detergent corresponding to the selected target detergent type A1 is increased by 10%. When the user washes clothes of the same weight next time, the calculated amount of detergent is LA1'=LA1*(1+10%).

[0096] Secondly, the calculated dosage of other types of detergents such as A2, A3...B1...are also changed accordingly to LA2'=LA2*(1+10%)*k1, LA3'=LA3*(1+10%)*k2..., LB1'=LB1*(1+10%)*k3..., where k1, k2...are coefficients when different detergents are adjusted to the same level of calculated dosage based on experiments).

[0097] Different detergent concentrations have different corresponding revision coefficients K. The higher the detergent concentration, the smaller the corresponding revision coefficient K, so that the washing effect remains unchanged when washing clothes of the same weight.

[0098] The above description 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 as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
