Description

Technical Field

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

[0002] "Washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration and other programs, such as washing machines, washer-dryers, etc.

[0003] The washing principle of a washing machine is to control the rotation of the impeller, stir the washing water in the washing machine barrel, create a strong water flow to flush and drive the clothes to turn over. The clothes are cleaned under the action of water flushing, turning and friction.

[0004] In order to improve the cleaning effect of washing machines on clothes, current washing machines generally choose to increase the impeller rotation-stop ratio and speed to increase the washing water flow intensity and thus improve the cleaning effect according to the degree of dirtiness of the clothes. However, this method will cause the clothes to become entangled, worn and severely wrinkled in the barrel, and it is inconvenient for users to take the clothes after washing.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The object of the present invention is to provide a control method for a washing device so as to improve the cleaning effect and washing efficiency of clothes and reduce the entanglement rate and wear rate of clothes during the washing process.

[0007] The present invention also provides a washing device to achieve the purpose of efficient washing of clothes, low wear on clothes during washing, and less wrinkles on clothes.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A control method for a washing device, the washing device comprising an impeller, the impeller being capable of performing forward and reverse movements of the same duration to form a washing water flow, the impeller being controlled to perform forward and reverse movements of different durations to form a reversing water flow, and after the reversing water flow is formed, the washing water flow is controlled to form the washing water flow for washing clothes.

[0010] Further, controlling the formation of the reverse water flow includes: controlling the forward rotation time t in the forward and reverse rotation cycle 正 Greater than the reversal time t 反 , or, control the alternating forward rotation time t 正 >Reversal time t 反 , reversal time t 反 >Forward rotation time t 正 procedure.

[0011] Further, the laundry information in the washing machine is obtained, and t 正 >t 反 Including: according to the obtained clothing information, select the corresponding forward rotation time t 正 and reversal time t 反 The ratio t 正 :t 反 ;

[0012] Preferably, the clothing information includes clothing weight, and the ratio t is controlled 正 :t 反 It is positively correlated with the weight of the clothes obtained.

[0013] Further, the laundry information in the washing device is obtained, and the alternate execution of t 正 >t 反 ,t 反 >t 正 The procedure includes: selecting the number of alternations corresponding to the clothing information according to the obtained clothing information;

[0014] Preferably, the clothing information includes clothing weight, and the number of alternations is controlled to be positively correlated with the acquired clothing weight.

[0015] Furthermore, the impeller can move in forward and reverse rotations with the same duration and a rotation speed lower than the corresponding rotation speed when the washing water flow is formed to form a shaking water flow, so as to determine whether the clothes in the washing device are entangled. If so, the shaking water flow is controlled to be formed first, and then the flipping water flow and the washing water flow are formed.

[0016] Further, the degree of entanglement of the clothes is divided into several entanglement levels from strong to weak. If the clothes are entangled, the entanglement level of the clothes is obtained, and the corresponding turning water flow intensity and / or washing water flow intensity is selected according to the obtained entanglement level;

[0017] Preferably, the stronger the degree of entanglement corresponding to the entanglement level of the clothes, the weaker the intensity of the turning water flow and / or the intensity of the washing water flow is controlled.

[0018] Furthermore, the preset time t 0 During the washing process, obtain the remaining washing time t and compare the obtained washing time t with the preset time t 0 The size of 0 , then control the formation of shaking water flow and stop washing.

[0019] Furthermore, obtaining the entanglement level of the clothes includes: obtaining the degree of intersection of different clothes in the washing device and the size of the crossed clothes. The higher the obtained degree of intersection and the larger the size, the higher the corresponding entanglement level.

[0020] Furthermore, the washing device has a database that pre-stores washing parameters corresponding to different clothing information, obtains the clothing information in the washing device, and determines whether the obtained clothing information belongs to the database. If not, the clothing information of the clothing and its corresponding washing parameters are updated to the database after washing is completed.

[0021] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0022] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0023] During the washing process of the present invention, the impeller is controlled to perform forward and reverse movements with different durations, so that the water flow is easy to flip up and down in the barrel body to form a flipping water flow. The flipping water flow drives the clothes to be vertically displaced and flipped up and down, thereby reducing the entanglement of the clothes in the barrel body, reducing the wear on the clothes, and avoiding the clothes from being wrinkled; the subsequent washing water flow can fully act on the flipped clothes, so that the flipped clothes can be fully washed under the scrubbing action of the washing water flow, thereby improving the cleaning effect of the clothes, without the need to additionally extend the washing time and washing intensity, saving time, electricity and water and effectively protecting the clothes.

[0024] The washing device of the present invention is controlled by the control method of the present invention, which improves the washing efficiency and cleaning effect of clothes while reducing the degree of entanglement and wear of clothes, making it less likely for the washed clothes to be wrinkled.

DETAILED DESCRIPTION

[0036] 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.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] 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.

[0039] "Washing equipment" refers to a general term for household appliances that can perform washing, dehydration and other procedures, such as washing machines, washer-dryers, etc. Figure 6 As shown, the washing device includes a barrel for accommodating clothes and a pulsator 4 rotatably arranged in the barrel. Specifically, the barrel includes:

[0040] An outer barrel 1, used for containing laundry water;

[0041] An inner tub 2, rotatably disposed in the outer tub 1, for containing laundry;

[0042] A pulsator 4 is rotatably disposed in the inner tub 2;

[0043] The motor is used to provide driving force to rotate at least one of the inner tub 2 and the pulsator 4.

[0044] like Figures 1 to 5 As shown, the present invention provides a control method for a washing device. In the present invention, the impeller 4 can make forward and reverse movements with the same duration to form a washing water flow. The impeller 4 is controlled to make forward and reverse movements with different durations to form a reversing water flow. After the reversing water flow is formed, the washing water flow is controlled to be formed for washing clothes.

[0045] In the present invention, the specific method of forming the inverted water flow includes: controlling the impeller 4 to perform continuous alternating forward and reverse motions, that is, switching to the reverse state without stopping after the impeller 4 finishes forward rotation, and the forward and reverse rotation durations are different, forming an upside-down inverted water flow in the barrel body, which is the inverted water flow.

[0046] Alternatively, the impeller 4 is controlled to perform a continuous forward rotation-pause-reverse movement, that is, after the impeller 4 finishes forward rotation, it pauses for a set time and then switches to a reverse state, and the forward and reverse rotation times are different, forming an upside-down water flow in the barrel body, which is an inverted water flow.

[0047] Alternatively, the impeller 4 and the inner tub 2 are controlled to perform alternating forward and reverse motions, that is, after the impeller 4 and the inner tub 2 finish forward rotation, they pause for a set time and switch to the reverse state, and the forward and reverse time lengths are different, so that a water flow that is reversed upside down in the barrel body is a reverse water flow; wherein, the impeller 4 and the inner tub 2 rotate in the same direction, such as: the impeller 4 and the inner tub 2 rotate forward or reverse at the same time, but the rotation speeds of the two can be the same or different, and can be specifically controlled according to actual conditions; for example: the rotation speed of the impeller 4 is 50rpm, and the rotation speed of the inner tub 2 is 400rpm; for another example: the rotation speed of the impeller 4 is 100rpm, and the rotation speed of the inner tub 2 is 100rpm.

[0048] In the present invention, the specific method of forming the washing water flow includes: controlling the barrel body and the impeller 4 to rotate in opposite directions, and performing alternating forward and reverse movements with the same duration in a forward rotation-stop-reverse cycle to form the washing water flow; or, only controlling the impeller 4 to perform alternating forward and reverse movements with the same duration in a forward rotation-stop-reverse cycle to form the washing water flow; the washing water flow rotates alternately in a clockwise and counterclockwise direction along the circumference of the barrel body.

[0049] Specifically, Figure 1 As shown, the control steps of the washing equipment include:

[0050] S1, start;

[0051] S2, preset total washing time t 总 ; For example: 20min;

[0052] S3, control the impeller 4 to perform forward and reverse movements with different durations to form a reverse water flow; for example: forward rotation for 2 seconds, reverse rotation for 1 second;

[0053] S4, control the pulsator 4 to make forward and reverse movements of the same duration to form a washing water flow; for example: forward rotation for 1.8s, reverse rotation for 1.8s;

[0054] S5, cumulative washing time t;

[0055] S6. Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, proceed to step S7; otherwise, return to step S3;

[0056] S7, washing ends.

[0057] In the present invention, the total washing time t 总 " is related to the weight and degree of dirtiness of the laundry to be washed. The heavier the laundry, the higher the degree of dirtiness. The corresponding "preset total washing time t 总 ”The bigger it is.

[0058] During the washing process of the present invention, the impeller 4 is controlled to perform forward and reverse movements with different durations, so that the water flow is easy to flip up and down in the barrel body to form a flipping water flow. The flipping water flow drives the clothes to be vertically displaced and flipped up and down, thereby reducing the entanglement of the clothes in the barrel body, reducing the wear on the clothes, and avoiding wrinkles on the clothes; the subsequent washing water flow can fully act on the flipped clothes, so that the flipped clothes can be fully washed under the scrubbing action of the washing water flow, thereby improving the cleaning effect of the clothes, without the need to additionally extend the washing time and washing intensity, saving time, electricity and water and effectively protecting the clothes.

[0059] As an embodiment of the present invention, controlling the formation of the reverse water flow includes: controlling the forward rotation time t in the forward and reverse rotation cycle 正 Greater than the reversal time t 反 Specifically, the control wheel 4 is rotated in accordance with the "forward rotation t 正 - Pause 停 -Reverse t 反 "The period of rotation, where t 正 >t 反 More specifically, it includes at least the following two control methods:

[0060] Method 1: If Figure 2 As shown, the control steps of the washing equipment include:

[0061] S1, start;

[0062] S2, preset total washing time t 总 ;

[0063] S3, control the pulsator 4 to rotate forward t 正 - Pause 停 -Reverse t 反 The period of rotation, t 正 >t 反 ;

[0064] S4, control the pulsator 4 to rotate forward t 正 - Pause 停 -Reverse t 反 The period of rotation, t 正 =t 反 ;

[0065] S5, cumulative washing time t;

[0066] S6. Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, proceed to step S7; otherwise, return to step S3;

[0067] S7, washing ends.

[0068] In this method, the pulsator 4 is controlled to rotate in the forward direction. 正 - Pause 停 -Reverse t 反 "The cycle of rotation forms a periodic up and down flipping, which realizes the continuous and rapid flipping of clothes, reduces the entanglement of clothes in the barrel, and reduces the wear and wrinkles on clothes. The turned clothes are rubbed and washed under the action of the washing water flow, and the washing effect is better, which can effectively remove the stains on the clothes.

[0069] Method 2: Control the alternating forward rotation time t 正 >Reversal time t 反 , reversal time t 反 >Forward rotation time t 正 procedure.

[0070] Specifically, the control steps include:

[0071] S1, start;

[0072] S2, preset total washing time t 总 ;

[0073] S3, control the alternating forward rotation time t 正 >Reversal time t 反 , reversal time t 反 >Forward rotation time t 正 The program, t 正 >t 反 ; For example: control the alternate execution of "forward 2s-pause 0.5s-reverse 1s-pause 0.5s-forward 1s-pause 0.5s-reverse 2s";

[0074] S4, control the pulsator 4 to rotate forward t 正 - Pause 停 -Reverse t 反 The period of rotation, t 正 =t 反 ;

[0075] S5, cumulative washing time t;

[0076] S6. Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, proceed to step S7; otherwise, return to step S3;

[0077] S7, washing ends.

[0078] In this method, the forward rotation time t is controlled alternately. 正 >Reversal time t 反 , reversal time t 反 >Forward rotation time t 正 The program forms turning water flows of different intensities at different positions in the barrel, which helps to fully turn the clothes in the barrel.

[0079] As an implementation method of this embodiment, the laundry information in the washing device is obtained, and t 正 >t 反 Including: according to the obtained clothing information, select the corresponding forward rotation time t 正 and reversal time t 反 The ratio t 正 :t 反 .

[0080] The clothing information includes: the material of the clothing, the type of clothing, the degree of dirtiness of the clothing, the amount of clothing put in, etc. Different clothing information has a corresponding forward rotation time t 正 and reversal time t 反 The ratio t 正 :t 反 Preferably, according to historical washing information, the proportion t corresponding to the best washing effect for different clothes is selected. 正 :t 反 , and use it as the ratio t corresponding to the clothing 正 :t 反 .

[0081] The dirtier the clothes are, the longer the forward rotation time t 正 and reversal time t 反 The ratio t 正 :t 反In this way, the intensity of the upside-down water flow is greater, and the clothes can be turned more fully. The fully turned clothes with high degree of dirt can be fully and thoroughly cleaned under the action of the subsequent washing water flow.

[0082] Further preferably, the clothing information includes clothing weight, and the ratio t is controlled 正 :t 反 It is positively correlated with the weight of the clothes obtained.

[0083] The heavier the clothes are, the more difficult it is to flip them. At this time, the control ratio t 正 :t 反 The larger the water flow, the stronger the up-and-down turning of the clothes can be, so as to effectively turn the clothes over and avoid the situation where the clothes cannot be turned up and down.

[0084] As another implementation of this embodiment: obtaining the laundry information in the washing device, controlling the alternate execution of t 正 >t 反 ,t 反 >t 正 The procedure includes: selecting the corresponding number of alternations according to the acquired clothing information.

[0085] For example, the dirtier the clothes are, the more alternations they will have. In this way, the water flow will turn upside down more often, and the clothes will turn upside down more frequently. For clothes with high dirtiness, the degree of cleaning of the clothes can be effectively improved by increasing the frequency of turning.

[0086] Further preferably, the clothing information includes clothing weight, and the number of alternations is controlled to be positively correlated with the obtained clothing weight. The heavier the weight of the clothing, the more clothing there is, the more difficult it is to flip it, and thus the more difficult it is to clean the clothing. At this time, the number of alternations is controlled to be larger, so that the number of upside-down water flows formed is also greater, and further, the upside-down flipping of the clothing is more frequent. For a large number of clothing, by increasing the flipping frequency, the degree of cleanliness of the clothing to be washed can be effectively improved.

[0087] As an embodiment of the present invention, the impeller 4 can move in forward and reverse directions with the same duration and a rotation speed lower than the corresponding rotation speed when the washing water flow is formed to form a shaking water flow, and judge whether the clothes in the washing device are entangled. If so, the shaking water flow is controlled to be formed first, and then the flipping water flow and the washing water flow are formed.

[0088] Furthermore, the forward rotation time and reverse rotation time in one rotation cycle when forming the shaking water flow are controlled to be shorter than the forward rotation time and reverse rotation time corresponding to forming the washing water flow and the flipping water flow.

[0089] Specifically, Figure 3 As shown, the control steps of the washing equipment include:

[0090] S1, start washing;

[0091] S2, preset total washing time ttotal;

[0092] S3, determining whether the clothes in the washing device are entangled; if so, executing step S4, otherwise, executing step S5;

[0093] S4, controlling the pulsator 4 to move in the same forward and reverse directions at a speed lower than the speed corresponding to the speed when the washing water flow is formed to form a shaking water flow;

[0094] S5, controlling the impeller 4 to perform forward and reverse movements with different durations to form a reversing water flow;

[0095] S6, controlling the pulsator 4 to move forward and reverse with the same duration to form a washing water flow;

[0096] S7, cumulative washing time t;

[0097] S8: Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, execute step S9; otherwise, return to step S3;

[0098] S9, washing ends.

[0099] The washing device of the present invention is provided with an image acquisition module 3 for acquiring an image in the barrel of the washing device. Step S3 of this embodiment includes: acquiring a picture in the barrel of the washing device, identifying position information of the clothes in the picture, and determining whether the clothes are entangled based on the identified position information.

[0100] In this embodiment, the shaking-off water flow has the same duration for forward and reverse rotations and has a lower rotation speed, so that the water flow formed is gentler and can shake off the tangled clothes to a certain extent, laying the foundation for the subsequent turning and washing of the clothes.

[0101] As an implementation method of this embodiment: the degree of entanglement of clothes is divided into several entanglement levels from strong to weak. If clothes are entangled, the entanglement level of the clothes is obtained, and the corresponding turning water flow intensity or washing water flow intensity or the turning water flow intensity and the washing water flow intensity are selected according to the obtained entanglement level.

[0102] For example, the degree of entanglement of clothes is divided into: "strong entanglement level, medium entanglement level, weak entanglement level" from strong to weak, and the "strong entanglement level, medium entanglement level, weak entanglement level" have corresponding turning water flow intensity and washing water flow intensity. According to the entanglement level of the current clothes, the corresponding turning water flow intensity and washing water flow intensity can be selected. Specifically, Figure 4 As shown, the control steps of the washing equipment include:

[0103] S1, start washing;

[0104] S2, preset total washing time t 总 ;

[0105] S3, determining whether the clothes in the washing device are entangled; if so, executing step S4, otherwise, executing step S7;

[0106] S4, obtaining the entanglement level of the clothing;

[0107] S5, selecting the turning water flow intensity and the washing water flow intensity corresponding to the entanglement level;

[0108] S6, controlling the pulsator 4 to move in the forward and reverse directions with the same duration and at a speed lower than the speed corresponding to the speed when the washing water flow is formed to form a shaking water flow;

[0109] S7, controlling the formation of an overturning water flow according to the selected overturning water flow intensity;

[0110] S8, controlling to form a washing water flow according to the selected washing water flow intensity;

[0111] S9, cumulative washing time t;

[0112] S10: Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, execute step S11; otherwise, return to step S3;

[0113] S11, washing ends.

[0114] In this embodiment, the tangle level of the clothes is different, and the corresponding turning water flow intensity and washing water flow intensity are also different, so that the turning water flow intensity and washing water flow intensity can be adjusted according to the current tangle situation of the clothes.

[0115] When the clothes are tangled in the washing machine, if the turning water flow and the washing water flow are stronger, the clothes will be more seriously agitated and entangled, that is, the entanglement of the clothes will be aggravated; conversely, when the clothes are not tangled in the washing machine, if the turning water flow and the washing water flow are stronger, the clothes will be fully turned over and it will not be easy to tangle the clothes together.

[0116] Therefore, in this embodiment, if the clothes are severely entangled, the turning water flow intensity and the washing water flow intensity can be controlled to be low to avoid further aggravating the entanglement of the clothes; conversely, if the clothes are lightly entangled, the turning water flow intensity and the washing water flow intensity can be controlled to be high so as to improve the turning and washing efficiency of the clothes.

[0117] Preferably, the stronger the degree of entanglement corresponding to the entanglement level of the clothes, the weaker the intensity of the turning water flow and the intensity of the washing water flow are controlled.

[0118] In this embodiment, the higher the entanglement level of the clothes, the more serious the entanglement of the clothes in the current washing device. Even if the clothes are shaken loose, the clothes may still be entangled to a certain extent. At this time, the flipping water flow intensity and the washing water flow intensity are controlled to be low to avoid high-intensity flipping and stirring that will aggravate the entanglement of the clothes.

[0119] As an embodiment of the present invention, the preset time t 0 During the washing process, obtain the remaining washing time t and compare the obtained washing time t with the preset time t 0 The size of 0 , then control the formation of shaking water flow and stop washing.

[0120] Specifically, Figure 5 As shown, the control steps of the washing equipment include:

[0121] S1, start washing;

[0122] S2, preset total washing time t 总 ,t 0 ; For example: t 总 20min, t 0 2min;

[0123] S3, determining whether the clothes in the washing device are entangled; if so, executing step S4, otherwise, executing step S7;

[0124] S4, obtaining the entanglement level of the clothing;

[0125] S5, selecting the turning water flow intensity and the washing water flow intensity corresponding to the entanglement level;

[0126] S6, controlling the pulsator to move in the same forward and reverse directions at a speed lower than the speed corresponding to the speed when the washing water flow is formed to form a shaking water flow;

[0127] S7, controlling the formation of an overturning water flow according to the selected overturning water flow intensity;

[0128] S8, controlling to form a washing water flow according to the selected washing water flow intensity;

[0129] S9, cumulative washing time t;

[0130] S10, calculate the remaining washing time t=t 总 -t;

[0131] S11. Determine whether the calculated duration t is less than t 0; If yes, go to step S12, otherwise, return to step S3;

[0132] S12, controlling the pulsator to move in the same forward and reverse directions at a speed lower than the speed corresponding to the speed when the washing water flow is formed to form a shaking water flow;

[0133] S13, cumulative washing time t;

[0134] S14: Determine whether the accumulated washing time t is greater than or equal to the preset total washing time t 总 ; If yes, execute step S15; otherwise, return to step S12;

[0135] S15, washing ends.

[0136] In this embodiment, when the remaining washing time t is less than the preset time t 0 It indicates that the washing process is about to be completed. At this time, the control is to form a shaking water flow before the end of the washing program so that the clothes can be shaken out after washing and the entanglement of clothes can be reduced as much as possible. This is conducive to the subsequent sufficient rinsing and stable dehydration of the clothes.

[0137] As an implementation of this embodiment, obtaining the entanglement level of the clothes includes: obtaining the degree of intersection of different clothes in the washing device and the size of the crossed clothes. The higher the obtained degree of intersection and the larger the size, the higher the corresponding entanglement level.

[0138] Among them, the image acquisition module 3 of the washing device is controlled to obtain the degree of intersection of different clothes in the washing device. Specifically, it includes: collecting color information of different clothes in the washing device, controlling the image acquisition module 3 to obtain images in the washing device, identifying the intersection of different colors on the image, and the more times different colors are crossed, the higher the degree of intersection of the clothes. The higher the degree of intersection and the larger the size of the clothes, the greater the difficulty of untangling, so the higher the corresponding entanglement level, that is, the entanglement level of the clothes can be accurately obtained in this embodiment, so as to accurately control the intensity of the shaking water flow, the flipping water flow, and the washing water flow.

[0139] As an embodiment of the present invention, the washing device has a database that pre-stores washing parameters corresponding to different clothing information, obtains clothing information in the washing device, and determines whether the obtained clothing information belongs to the database. If not, the clothing information and the corresponding washing parameters of the clothing are updated to the database after washing is completed; if so, washing is directly performed according to the washing parameters corresponding to the clothing information in the database.

[0140] More specifically, if the acquired clothing information does not belong to the database, it is determined whether the clothing in the washing device is entangled. If so, the shaking water flow is controlled to be formed first, and then the turning water flow and the washing water flow are formed. The strength of the shaking water flow, the turning water flow, and the washing water flow is adjusted according to the entanglement situation. The more serious the clothing entanglement is, the longer the duration of the shaking water flow is, so as to fully shake the clothing.

[0141] In this embodiment, if the acquired clothing information belongs to the database of the washing device, the washing parameters corresponding thereto are directly retrieved without setting the washing parameters according to the actual washing situation, thereby simplifying the control steps of the washing device. If the acquired clothing information does not belong to the database of the washing device, the washing parameters are set according to the actual washing situation, and the washing parameters are updated to the database to facilitate the subsequent use of the washing device to wash the same type of clothing.

[0142] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0143] The washing device of the present invention is controlled by the control method of the present invention, which improves the washing efficiency and cleaning effect of clothes while reducing the degree of entanglement and wear of clothes.

[0144] 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.
