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 clothing processing device and the clothing processing device. Background Art

[0002] The principle behind using detergent for washing clothes is that detergents contain active ingredients that react with stains on clothing, weakening their adhesion and dissolving them. For example, the two most common stains on clothing are protein and fatty acids and their esters, commonly known as grease. The ingredients in detergents that dissolve these two stains are enzymes, primarily alkaline protease and alkaline lipase. The activity of these enzymes is temperature-dependent; excessively high or low temperatures can reduce their activity. Furthermore, proteins denature, coagulating at high temperatures and significantly reducing their solubility. Therefore, an appropriate wash water temperature maximizes the effectiveness of the detergent's active ingredients in dissolving stains. Controlling wash water temperature can significantly improve laundry quality.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The first object of the present invention is to overcome the deficiencies of the prior art and to provide a method for controlling a laundry processing device that can wash the active ingredients of a detergent within their optimal active temperature, thereby effectively improving the washing effect of the laundry.

[0005] A second object of the present invention is to provide a clothes treating apparatus to which the above-mentioned clothes treating apparatus control method is applied.

[0006] To achieve the first purpose, the basic concept of the technical solution adopted by the present invention is:

[0007] A method for controlling a clothes processing device, comprising:

[0008] Detecting the type of stains on the clothes, and selecting and adding a detergent containing active ingredients that dissolve the corresponding type of stains according to the type of stains on the clothes;

[0009] selecting the optimal active temperature range of at least one active ingredient in the detergent as the target washing temperature range;

[0010] During the main washing stage, the washing water is heated to the target washing temperature range.

[0011] Preferably, the clothing treatment device detects the content of each type of stain on the clothing and obtains the action time of each type of active ingredient to dissolve the stain, and determines the temperature holding time of each target washing temperature range according to the content of each type of stain and the action time of each type of active ingredient;

[0012] The temperature of the wash water is maintained within the corresponding target wash temperature range within the temperature holding time corresponding to each stain type.

[0013] Preferably, it is determined whether the optimal activity temperature ranges of each selected active ingredient have an intersection; if so, the intersection of the optimal activity temperature ranges with the intersection and the optimal activity temperature range without the intersection is set as the target washing temperature range; if not, the optimal activity temperature range of each selected active ingredient is set as the target washing temperature range;

[0014] The washing water is heated in order from low to high temperature to the target washing temperature range.

[0015] Preferably, the laundry processing device pre-stores a first preset value, and after the main washing is completed, it is determined whether the residual degree of each type of laundry stain is lower than the first preset value;

[0016] If yes, the process enters the rinse phase; if no, the main wash cycle for the clothes is performed again.

[0017] Preferably, the laundry processing device further pre-stores a second preset value, the first preset value and the second preset value are set according to standard values ​​of cleaning rates of various active ingredients on corresponding stains, and the first preset value is smaller than the second preset value;

[0018] After the main washing is completed, determining whether the residual degree of each type of clothing stain is lower than a second preset value;

[0019] If so, it is determined that the stain type detection of the clothes is correct and the rinsing stage is entered; if not, it is determined that there is an error in the stain type detection of the clothes, and the stain type detection and main washing of the clothes are performed again.

[0020] Preferably, when the re-detection result of the incorrect clothing stain type is determined to be the same as the first detection result, the clothing processing device provides the user with a method of manually selecting the clothing stain type.

[0021] Preferably, when the main wash of the clothes is performed again, the water level remains unchanged, and the concentration of the detergent added for the first wash is reduced according to the ratio of the residual amount of stains on the clothes to the content of stains before washing, and the detergent is added.

[0022] To achieve the second purpose, the basic concept of the technical solution adopted by the present invention is:

[0023] A clothing processing device that applies the above-mentioned clothing processing device control method is provided with a detection unit and a control unit. The detection unit detects the stain information of the clothing and sends it to the control unit. The control unit determines the type, content and residual amount of the clothing stains based on the received information.

[0024] Preferably, a soaking time T2 is provided, and the detection unit is provided outside the washing tub;

[0025] After the first washing phase of the clothes is completed and the clothes are soaked for a time period T2, the washing tub discharges the washing water to the detection unit, and the detection unit detects the stain information in the washing water and sends it to the control unit;

[0026] The clothes processing device replenishes water and adds detergent after the washing water is discharged from the washing tub, and starts the main washing after the water level reaches the first water filling completion level.

[0027] Preferably, the control unit determines the type, content and residual amount of the clothing stains by using at least one of the information of color, concentration, shape, area, reflectivity and distribution uniformity of the clothing stains detected by the detection unit.

[0033] (5) The present invention provides a control method for a clothing processing device and a clothing processing device, which intermittently feeds water during the initial washing stage of the clothes, so that the clothes have sufficient soaking time, avoiding excessive water intake at one time, which causes the concentration of detergent to decrease and the clothes to be washed uncleanly.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0043] Example 1

[0044] The two most common stains on clothing in daily life are protein and fatty acids and their esters, commonly known as grease. The ingredients in detergents that dissolve these two stains are enzymes, primarily alkaline protease and alkaline lipase. The activity of these enzymes is temperature-dependent; excessively high or low temperatures can reduce their activity. Furthermore, proteins denature, coagulating at high temperatures and significantly reducing their solubility. Therefore, an appropriate wash water temperature maximizes the effectiveness of the active ingredients in detergents in dissolving stains. Controlling wash water temperature can significantly improve laundry quality.

[0045] In order to achieve the best effect of detergent in dissolving stains, improve the cleaning rate of clothes and enhance the user's laundry experience, such as Figure 1 As shown, this embodiment provides a method for controlling a clothes processing device, including:

[0046] After a user puts clothes into a washing tub and starts the clothes treating device, the clothes treating device detects stains on the clothes.

[0047] Optionally, the laundry treatment device detects the type of stain on the laundry.

[0048] Preferably, the laundry processing device rotates the washing drum to turn the laundry over for detection, which can then perform a more comprehensive detection of the stains on the laundry, avoiding omissions in the types of stains.

[0049] After the clothes treating device detects the type of stains on the clothes, it selects a detergent containing active ingredients that dissolve the corresponding type of stains according to the type of stains on the clothes.

[0050] The laundry treatment device weighs the laundry in the washing tub to determine the amount of detergent to be added. Alternatively, the laundry treatment device detects the amount of stains on the laundry and determines the amount of detergent to be added based on the amount of stains.

[0051] The optimal active temperature range of at least one active ingredient in the detergent is selected as the target washing temperature range, the selected detergent is added, and in the main washing stage after the water intake is completed, the washing water is heated to the target washing temperature range.

[0052] Preferably, the clothing processing equipment detects the content of various types of stains on the clothing and obtains the action time of various types of active ingredients to dissolve the stains, and determines the temperature holding time of each target washing temperature range based on the content of various types of stains and the action time of various types of active ingredients; and maintains the temperature of the washing water within the corresponding target washing temperature range within the temperature holding time corresponding to each type of stain.

[0053] The laundry treatment device determines whether the optimal activity temperature ranges of each selected active ingredient intersect; if so, the intersection of the optimal activity temperature ranges that intersect and the optimal activity temperature range that does not intersect is set as the target washing temperature range; if not, the optimal activity temperature range of each selected active ingredient is set as the target washing temperature range;

[0054] When heating to the target washing temperature range, the target washing temperature ranges are first sorted in order from low to high temperature, and the washing water is heated to the target washing temperature range in sequence.

[0055] Optionally, the action time of each type of active ingredient in dissolving stains is obtained through experiments or common knowledge and is pre-stored in the clothing treatment device.

[0056] For example:

[0057] If the optimal activity temperatures of the two active enzymes, alkaline protease and alkaline lipase, are 39°C-41°C and 43°C-44°C respectively, 39°C-41°C and 43°C-44°C are selected as the target washing temperature ranges respectively. At the same time, based on the content of protein stains and oil stains and the action time of alkaline protease and alkaline lipase in dissolving stains, the temperature holding times are judged to be 10 minutes and 12 minutes respectively.

[0058] S1: After the water is supplied to the laundry processing device, the water in the washing tub begins to be heated.

[0059] S2: First, the washing water is heated to the target washing temperature of 39℃-41℃, and the washing drum is rotated at a faster speed to perform the main wash on the clothes. At the same time, the clothing processing equipment also detects the temperature of the washing water in real time and intermittently heats the water in the washing drum to ensure that the temperature of the washing water does not drop below the target washing temperature. The main wash is performed at a temperature of 39℃-41℃ for 10 minutes.

[0060] S3: After 10 minutes, the laundry processing device continues to heat the water in the washing tub to a target washing temperature range of 43°C-44°C, and performs a main wash at a temperature of 43°C-44°C for 12 minutes.

[0061] S4: The main wash is finished and the rinse phase begins.

[0062] Since the active ingredients in detergents play a major role in cleaning stains from clothing, the above configuration ensures that each type of stain in clothing has a corresponding active ingredient in the detergent to dissolve it, and allows the active ingredients in the detergent to be washed within their optimal activity temperature, effectively improving the washing effect of clothing. Furthermore, the system can automatically detect and identify stain information on clothing and automatically select the appropriate detergent based on the stain information, eliminating manual selection by the user and improving the user experience.

[0063] In order to further improve the washing effect of clothes, preferably, the clothes processing equipment also pre-stores a first preset value. After the above-mentioned main washing is completed, it is determined whether the residual degree of stains on each type of clothes is lower than the first preset value; if so, the rinsing stage is entered; if not, the main washing of the clothes is performed again.

[0064] Optionally, the ratio of the residual amount of each type of stain on the clothes after the main wash to the content of each type of stain before washing the clothes is used as the residual degree of the stain on the clothes.

[0065] Preferably, when the main wash of the clothes is repeated, the clothes processing device determines the temperature holding time of each target washing temperature range according to the residual amount of each type of stain and the action time of each type of active ingredient.

[0066] When the main wash of the clothes is repeated, the water level remains unchanged. According to the ratio of the residual amount of stains on the clothes to the content of stains before washing, the concentration of detergent added in the first wash is reduced and detergent is added.

[0067] For example, if the second preset value for the residual protein stain is set to 8%, and the residual protein stain on the clothes is detected to be 10%, it is determined that the clothes should be washed again. The water level for this main wash is the same as that for the previous wash, and the amount of detergent added can be set to 20% of the amount of detergent added in the previous main wash based on the residual protein stain of 10%.

[0068] Optionally, after the main wash cycle is complete, the process continues to determine whether the residual stain level for each type of clothing item is below a first preset value. If so, the process proceeds to the rinse cycle. If not, the main wash cycle is repeated. This process repeats until the residual stain level for each type of clothing item is below the first preset value. Alternatively, after the main wash cycle is complete, the process proceeds to the rinse cycle.

[0069] By running this step in a cycle, the cleaning rate of clothes can be effectively improved and the user's laundry experience can be enhanced.

[0070] In order to give the clothes sufficient soaking time when water is added, and to avoid too much water added at one time causing too low a concentration of detergent and affecting the washing effect, preferably, the clothes processing device performs intermittent water addition during the water addition stage of the first washing stage of the clothes.

[0071] The clothes processing device is further provided with a soaking time T1, and detects the water level of the washing water in real time during the intermittent time to determine whether the water level of the washing water changes during the soaking time T1.

[0072] If yes, it means that the clothes have not been fully soaked and are still absorbing water, so water continues to be added after the interval time is reached; if no, it means that the clothes have been fully soaked and are no longer absorbing water, so water is stopped from being added and washing is started, and the water level value H is recorded.

[0073] Since the water level needs to remain unchanged when the main wash of clothes is repeated, the recorded water level value H is used when the water is repeated for the main wash.

[0074] Example 2

[0075] Because the characteristics of two stains may be extremely similar, the type of stain may be misidentified, affecting the cleaning rate of the clothes.

[0076] To avoid this problem, if Figure 2 As shown, the control method of the clothes processing device provided in this embodiment includes:

[0077] The laundry processing device is provided with a second preset value, and after the main washing is completed, it is determined whether the residual degree of each type of laundry stain is lower than the second preset value;

[0078] If so, the stain type of the clothes is determined to be correctly detected and the rinse stage is entered;

[0079] If not, it is determined that there is an error in the stain type detection of the clothes, and the stain type detection and the main washing of the clothes are performed again.

[0080] Both the first preset value and the second preset value can have multiple values. Each type of stain has its corresponding first preset value and second preset value. The clothing processing device sets the first preset value and the second preset value according to the multiples of the standard value of the cleaning rate of the corresponding stains by various active ingredients.

[0081] The first preset value is smaller than the second preset value.

[0082] For example, assuming that the standard values ​​of the cleaning rates of alkaline protease and alkaline lipase on clothes at the optimal activity temperature are generally 92% and 96% respectively, the standard values ​​of their residual degrees are 8% and 4% respectively.

[0083] In this case, the first preset value for determining the residual degree of protein stains can be set to 40%, and the first preset value for determining the residual degree of oil stains can be set to 20%. After the main wash phase, if the residual degree of protein stains is still not less than 40% or the residual degree of oil stains is still not less than 20%, it is determined that there is an error in the stain type detection of the clothing.

[0084] The second preset value for determining the residual protein stain level can be set to 8%, and the first preset value for determining the residual oil stain level can be set to 4%. After the main wash, if the residual protein stain level is still not less than 8% or the residual oil stain level is still not less than 8%, the clothes are deemed not clean and the main wash is repeated.

[0085] Preferably, there are two situations for the results of re-detecting the stain type: when the re-detection result is different from the initial detection result and it is determined that there is an erroneous clothing stain type, the clothing processing device selects detergent according to the re-detection result and performs the main wash of the clothing again; when the re-detection result is the same as the initial detection result and it is determined that the clothing processing device cannot correctly identify the type of stain, and a method for manually selecting the stain type of the clothing is provided to the user. After the user manually selects the stain type of the clothing, the clothing processing device selects detergent and performs the main wash of the clothing again.

[0086] After the main washing of the clothes is completed again, the clothes processing device enters the rinsing stage, or continues to determine whether the residual degree of each type of clothes stain is lower than the first preset value.

[0087] Preferably, after the user manually selects the stain type of the clothes, the clothes processing device modifies its own stain analysis model according to the stain type selected by the user.

[0088] Preferably, when the main wash of the clothes is performed again, the water level remains unchanged, and the concentration of the detergent added is proportionally reduced according to the residual degree of stains on the clothes.

[0089] Example 3

[0090] The clothes processing device provided in this embodiment applies the clothes processing device control method described in the first embodiment.

[0091] The clothes treating apparatus is provided with a detection unit and a control unit.

[0092] Optionally, the detection unit is an image sensor arranged in the washing tub.

[0093] Preferably, the laundry processing device rotates the washing drum to turn the laundry over for detection, which can then perform a more comprehensive detection of the stains on the laundry, avoiding omissions in the types of stains.

[0094] The detection unit detects at least one of the following information: color, concentration, shape, area, reflectivity, and distribution uniformity of the clothing stains, and sends it to the control unit. The control unit determines the type, content, and residual amount of the clothing stains based on the received information.

[0095] The stain analysis model in the control unit can determine the type, content and residual amount of clothing stains by identifying and analyzing at least one of the following information: color, concentration, shape, area, reflectivity and distribution uniformity of clothing stains.

[0096] For example, if a stain is bright red or dark red, has a high color concentration that covers the color of the clothing, is irregular in shape, has poor reflectivity, and is evenly distributed within the area without significant concentration differences, the stain analysis model can determine that it is a blood stain, or a protein stain.

[0097] The stain is yellow or red in color, has a low color concentration, does not cover the color of the clothing itself, has a regular edge shape, high reflectivity, and is relatively evenly distributed within the distribution area without large concentration differences. In this case, the stain analysis model can determine that it is an oil stain.

[0098] Preferably, the detection unit detects at least one of the following information: color, concentration, shape, area, reflectivity, and distribution uniformity of the same type of stains on each piece of clothing to determine the content and residual amount of the stains of this type.

[0099] Preferably, before the clothes processing device leaves the factory, a large amount of analysis and training has been carried out on the stain analysis model in the control unit to ensure the reliability of its judgment.

[0100] Preferably, the control unit also determines the temperature holding time of each target washing temperature range according to the content and residual amount of each type of stain.

[0101] The clothing processing device provided in this embodiment can automatically detect and identify the stain information of clothes, and automatically select suitable detergents based on the stain information, avoiding manual selection by users and improving the user experience; and can significantly improve the cleaning rate of clothes and improve the user's satisfaction with laundry.

[0102] Example 4

[0103] As another implementation of the detection unit in the third embodiment, the detection unit of the clothes processing device provided in this embodiment is arranged outside the washing tub.

[0104] Optionally, the detection unit is connected to a branch pipe branched from the drain pipe of the washing tub, and the detection unit is composed of a transparent accommodating cavity for accommodating washing water and an image sensor.

[0105] The clothing processing device is provided with a soaking time T2. After the water intake of the clothes is completed in the first washing stage and the clothes are soaked for T2, the washing tub discharges the washing water to the detection unit. The detection unit detects the stain information in the washing water and sends it to the control unit.

[0106] Specifically, the washing drum discharges washing water into the transparent receiving chamber of the detection unit. The image sensor detects the floating condition of the stains in the washing water in the transparent receiving chamber, the size of the stain impurities, turbidity, color, transmittance and other information and sends it to the control unit. The control unit determines the type and content of the stains on the clothes based on the received information.

[0107] Optionally, the soaking time T2 may be set based on an average of the time it takes for most common stains to dissolve in clean water.

[0108] After the washing water is discharged from the washing drum for testing, the clothes processing equipment replenishes water and adds detergent. The detergent is flushed into the washing drum along with the replenished washing water until the water level value H for the first water inflow is reached, and then the main wash begins.

[0109] Compared with direct testing of clothes, this stain detection method can avoid incomplete detection caused by insufficient stacking and stretching of clothes, which may result in insufficient matching of detergent selection and affect the washing effect of clothes.

[0110] After adopting the above technical solution, the control method and clothing processing device provided by the present invention have the following beneficial effects compared with the prior art:

[0111] (1) The control method and clothing processing device provided by the present invention can dissolve various types of stains in clothing with corresponding active ingredients of detergent, and can wash the active ingredients of detergent within their optimal active temperature, thereby effectively improving the cleaning rate of clothing.

[0112] (2) The present invention provides a control method and a clothing processing device, which are provided with a detection program to avoid errors in stain type detection, thereby avoiding the situation where incorrect detergent selection is caused by errors in stain type detection, thereby resulting in poor washing effect of clothes.

[0113] (3) The present invention provides a method for controlling a clothing processing device and a clothing processing device, which can automatically detect and identify the stain information of clothing and automatically select a suitable detergent based on the stain information, thereby avoiding manual selection by the user and improving the user experience.

[0114] (4) The control method and clothing processing device provided by the present invention are provided with a program for detecting the residual rate of stains on clothing, which can improve the cleaning rate of clothing and avoid unclean washing of clothing.

[0115] (5) The present invention provides a control method for a clothing processing device and a clothing processing device, which intermittently feeds water during the initial washing stage of the clothes, so that the clothes have sufficient soaking time, avoiding excessive water intake at one time, which causes the concentration of detergent to decrease and the clothes to be washed uncleanly.

Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention.
