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 machine has the function of automatically adding detergent. By detecting the weight of the clothes to be washed, the amount of detergent to be added is determined, and the determined amount of detergent is controlled to be added into the washing device.

[0004] However, in the current process of adding detergent, the detergent is only added to a local area in the washing device, but the detergent cannot be evenly dispersed on the clothes. Therefore, the treatment effect of the detergent on the clothes is poorly uniform.

[0005] Based on this, some washing machines control the drum to rotate forward and reverse during the process of adding detergent. However, this control method has a poor effect of evenly distributing the detergent. After the detergent is added, it will penetrate into the clothes in a short period of time. Even if the drum is controlled to rotate forward and reverse, the detergent that has penetrated into the clothes cannot be evenly distributed on other clothes. At the same time, clothes in some areas will be repeatedly sprayed with detergent, while clothes in some areas will not be stained with detergent.

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

[0007] The object of the present invention is to provide a control method for a washing machine so as to achieve the purpose of spraying detergent evenly on clothes.

[0008] Another object of the present invention is to provide a washing device that is controlled by the control method of the present invention to achieve the purpose of improving the uniformity of washing clothes by the detergent.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A control method for a washing device controls a barrel and / or a pulsator of the washing device to rotate in one direction during the process of adding detergent to the washing device.

[0011] Furthermore, the preset water level value V 0 , controlling the barrel and / or the impeller to rotate in one direction includes: obtaining the water level V of the washing device, comparing the obtained water level V with the preset water level value V 0 If V ≥ V 0 , then the one-way rotation is controlled to stop.

[0012] Furthermore, the amount of detergent added is obtained, and the preset water level value V is controlled. 0 It is positively correlated with the amount of detergent obtained.

[0013] Furthermore, the preset water inlet time t 0 , preset water level value V 0 , controlling the barrel and / or the impeller to rotate in one direction includes: accumulating water inflow time t, when the accumulated water inflow time t reaches the preset water inflow time t 0 When the current water level V is obtained, if the obtained water level V is less than the preset water level V 0 , then the one-way rotation is controlled to stop.

[0014] Furthermore, the washing device includes a motor, and a preset current value I 0 , controlling the barrel and / or the impeller to rotate in one direction includes: detecting the current value I of the motor, comparing the detected current value I with the preset current value I 0 The size of 0 , the one-way rotation is controlled to pause for a set time and then resume the one-way rotation.

[0015] Furthermore, during the process of re-performing unidirectional rotation, if the detected current value I is greater than or equal to the preset current value I 0 , the one-way rotation is controlled to pause for a set time and then resume the one-way rotation; otherwise, the one-way rotation is controlled to continue.

[0016] Furthermore, the preset number N 0 , the cumulative number of one-way rotation pauses and then restarts is N, if the cumulative number N ≥ N 0 , then the one-way rotation is controlled to stop.

[0017] Furthermore, controlling the barrel body and / or the impeller to rotate in one direction includes: controlling the impeller and the barrel body to rotate in opposite directions and in one direction, or controlling the impeller and the barrel body to rotate in the same direction and in one direction, or controlling the impeller to rotate in one direction and the barrel body not to rotate.

[0018] Furthermore, the preset load weight G 0 , obtain the load weight G in the washing device, and compare the obtained load weight G with the preset load weight G 0 The size of G≥G 0 , then the impeller and the barrel body are controlled to rotate in opposite and unidirectional directions.

[0019] The present invention also provides a washing device which is controlled by any control method described in the above technical solutions.

[0020] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0021] In the present invention, the barrel body and the impeller are controlled to rotate unidirectionally to drive the clothes in the barrel body of the washing device to move in a directional manner. In this way, during the process of adding detergent, the detergent can be evenly sprinkled on the clothes, and there will be no situation where clothes in some areas are repeatedly sprayed with detergent while clothes in other areas are not stained with detergent; in addition, the directional movement of the clothes can prevent the detergent from being concentrated in the clothes with strong water absorption and unable to be stained on other clothes; in the control method of the present invention, the detergent can be evenly dispersed on the clothes, thereby improving the uniformity of washing the clothes by the washing device.

[0031] 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.

Therefore, they cannot be understood as limitations on the present invention.

[0033] 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.

[0034] "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.

[0035] The washing device comprises a detergent delivery module and a barrel body for accommodating clothes. The detergent delivery module contains detergent. When water enters the washing device, the incoming water flow can flush the detergent in the detergent delivery module into the barrel body for washing clothes.

[0036] The present invention provides a control method for a washing device. When water is introduced into the washing device and detergent is added, a barrel body, a pulsator, or both the barrel body and the pulsator of the washing device are controlled to rotate in one direction.

[0037] More specifically, if Figure 1 As shown, the control steps are as follows:

[0038] S1, start;

[0039] S2, obtaining the amount of detergent to be put in a;

[0040] S3, adding detergent;

[0041] S4, controlling the impeller of the washing equipment to rotate in one direction;

[0042] S5, obtaining the amount b of detergent added;

[0043] S6, determining whether the obtained amount b of detergent to be put in is greater than or equal to the amount a to be put in; if so, executing step S7; otherwise, returning to step S4;

[0044] S7. End.

[0045] Among them, in step S2, the corresponding amount a to be put in is selected according to the load in the barrel of the washing equipment, and the larger the load, the larger the corresponding amount a to be put in.

[0046] In the present invention, the barrel body and the impeller are controlled to rotate unidirectionally to drive the clothes in the barrel body of the washing device to move in a directional manner. In this way, during the process of adding detergent, the detergent can be evenly sprinkled on the clothes, and there will be no situation where the clothes in some areas are repeatedly sprayed with detergent while the clothes in other areas are not contaminated with detergent. In the control method of the present invention, the detergent can be evenly dispersed on the clothes, thereby improving the uniformity of washing the clothes by the washing device.

[0047] In particular, for some clothes with strong water absorption, the detergent will quickly penetrate into the clothes after coming into contact with the clothes, so that the detergent cannot be contaminated to other clothes, and the washing effect on other clothes is poor. After adopting the control method of the present invention, the detergent will evenly adhere to each piece of clothing in the washing device, ensuring a better washing effect.

[0048] As an embodiment of the present invention, the preset water level value V 0 , controlling the barrel and / or the impeller to rotate in one direction includes: obtaining a water level value V of the washing device, comparing the obtained water inlet level V with a preset water level value V 0 If V ≥ V 0 , then the one-way rotation is controlled to stop.

[0049] Specifically, as an implementation method of this embodiment, Figure 2 As shown, the control steps of the washing equipment are as follows:

[0050] S1, start;

[0051] S2, preset water level value V 0 ;

[0052] S3, adding detergent into water;

[0053] S4, controlling the impeller of the washing equipment to rotate in one direction;

[0054] S5, obtaining the water inlet level V of the washing equipment;

[0055] S6: Determine whether the obtained water level V is greater than or equal to the preset water level value V 0 ; If yes, proceed to step S7; otherwise, return to step S4;

[0056] S7, control the one-way rotation to stop.

[0057] In step S2 of this embodiment, the preset water level value V 0 The total water inlet level is determined according to the load in the washing equipment barrel. The greater the load, the higher the corresponding total water inlet level.

[0058] In the present invention, when the obtained water inlet level V is greater than or equal to the preset water level value V 0 It indicates that the current water level is high and the detergent has been completely put into the barrel of the washing machine. Under the action of the unidirectional rotation of the impeller, the detergent has been evenly stained on the load in the barrel, i.e. the clothes. At this time, the unidirectional rotation is controlled to stop and the washing program is started to wash the clothes to improve the washing efficiency of the clothes.

[0059] As an implementation method of this embodiment, the amount of detergent added is obtained, and the preset water level value V is controlled. 0 It is positively correlated with the amount of detergent obtained.

[0060] In the washing device, different load weights and different load dirtiness have corresponding detergent delivery amounts. The greater the load weight and the higher the dirtiness, the greater the corresponding detergent delivery amount. Obtaining the detergent delivery amount includes: obtaining the load weight and the load dirtiness in the washing device, and using the detergent delivery amount corresponding to the obtained load weight and dirtiness as the obtained detergent delivery amount.

[0061] In this embodiment, the more the amount of detergent is obtained, the more detergent needs to be put into the barrel of the washing device. At this time, the preset water level value V is controlled. 0 The pulsator or barrel of the washing device can maintain unidirectional rotation at least during the whole process of adding detergent, so that the detergent can be evenly stained on the clothes.

[0062] As an embodiment of the present invention, the preset water inlet time t 0 , preset water level value V 0 , controlling the barrel and / or the impeller to rotate in one direction includes: accumulating water inflow time t, when the accumulated water inflow time t reaches the preset water inflow time t 0 When the current water level V is obtained, if the obtained water level V is less than the preset water level V 0 , then the one-way rotation is controlled to stop.

[0063] More specifically, if Figure 3 As shown, the control steps include:

[0064] S1, start;

[0065] S2, preset water level value V 0 , water inlet time t 0 ; Among them, the preset water inlet time t 0 Under normal water pressure, water enters to the preset water level value V 0 The theoretical time required for

[0066] S3, adding detergent into water;

[0067] S4, controlling the impeller of the washing equipment to rotate in one direction;

[0068] S5, cumulative water inflow time t;

[0069] S6. Determine whether the accumulated water inflow time t is greater than or equal to the preset water inflow time t 0 ; If yes, proceed to step S7; otherwise, return to step S4;

[0070] S7, obtaining the water inlet level V of the washing equipment;

[0071] S8: Determine whether the obtained water level V is less than the preset water level V 0 ; If yes, execute step S9; otherwise, return to step S10;

[0072] S9, control the one-way rotation to stop;

[0073] S10, controlling the execution of a washing program.

[0074] In this embodiment, when the accumulated water inflow time t reaches the preset water inflow time t 0 When the water level V is less than the preset water level V 0 , it indicates that the current water inflow is abnormal. At this time, the one-way rotation is controlled to stop in order to correct the water inflow abnormality.

[0075] As another embodiment of the present invention, the washing device includes a motor, which is used to provide power for the rotation of the barrel and the impeller. During the rotation of the barrel and the impeller, once a wet load is placed or a load is stuck between the impeller and the barrel, the load cannot rotate unidirectionally with the impeller, but is blocked or blocked. To address this problem, the control method provided in this embodiment is as follows:

[0076] Preset current value I 0 , controlling the barrel and / or the impeller to rotate in one direction includes: detecting the current value I of the motor, comparing the detected current value I with the preset current value I 0 The size of 0 , the one-way rotation is controlled to pause for a set time and then resume the one-way rotation.

[0077] Specifically, Figure 4As shown, the control steps of the washing equipment include:

[0078] S1, start;

[0079] S2, preset current value I 0 , set duration s;

[0080] S3, adding detergent;

[0081] S4, controlling the impeller of the washing equipment to rotate in one direction;

[0082] S5, detecting the current value I of the motor;

[0083] S6: Determine whether the current value I of the detection motor is greater than or equal to the preset current value I 0 ; If yes, proceed to step S7; otherwise, return to step S4;

[0084] S7, controlling the one-way rotation to pause for a set time s and then resume the one-way rotation; the set time can be set according to actual conditions, for example: 10s.

[0085] More specifically, the washing machine is provided with a rear current detection device, and in step S5, the current detection device is controlled to be turned on to detect the current value of the motor.

[0086] In this embodiment, if the detected current value I is greater than or equal to the preset current value I 0 , it indicates that the load may be stuck. At this time, the one-way rotation is controlled to pause for a set period of time and then resumed. This avoids detection interference caused by clothing obstruction. In addition, the position of the load will shift due to inertia when it stops, which helps to repair the stall caused by load obstruction.

[0087] As an implementation method of this embodiment, during the process of re-performing unidirectional rotation, if the detected current value I is greater than or equal to the preset current value I 0 , the one-way rotation is controlled to pause for a set time and then resume the one-way rotation; otherwise, the one-way rotation is controlled to continue.

[0088] Specifically, Figure 5 As shown, the control steps include:

[0089] S1, start;

[0090] S2, preset current value I 0 , set duration s;

[0091] S3, adding detergent;

[0092] S4, controlling the impeller of the washing equipment to rotate in one direction;

[0093] S5, detecting the current value I of the motor;

[0094] S6: Determine whether the current value I of the detection motor is greater than or equal to the preset current value I 0 ; If yes, proceed to step S7; otherwise, return to step S4;

[0095] S7, controlling the one-way rotation to pause for a set time s and then resume the one-way rotation.

[0096] S8. Detect the current value I of the motor.

[0097] S9: Determine whether the current value I of the detection motor is greater than or equal to the preset current value I 0 ; If yes, return to step S7; otherwise, execute step S10;

[0098] S10, controlling the continuous one-way rotation.

[0099] In this embodiment, if the current value I detected during the unidirectional rotation after the pause of the set time is still greater than or equal to the preset current value I 0 , it indicates that the stall situation has not been improved. At this time, the one-way rotation is controlled to pause for a set period of time and then resume the one-way rotation, and this cycle is repeated to further repair the stall situation.

[0100] On the contrary, if the current value I detected during the unidirectional rotation after pausing for the set time is less than the preset current value I 0 , it indicates that the one-way rotation has returned to normal and there is no jam. At this time, the control continues to rotate in one direction so that the detergent put in can be evenly stained on the load.

[0101] As an implementation method of this embodiment, the preset number N 0 , the cumulative number of one-way rotation pauses and then restarts is N, if the cumulative number N ≥ N 0 , then the one-way rotation is controlled to stop.

[0102] In this embodiment, if the cumulative number of times N ≥ N 0 , it indicates that the one-way rotation has been paused and then restarted for many times, which means that the operation has not effectively improved the stall situation. At this time, the one-way rotation is controlled to stop so that the user can manually intervene to check the stall situation.

[0103] As an embodiment of the present invention, during the process of adding detergent to the washing machine, the impeller and the barrel are controlled to rotate in opposite directions and in one direction. The one-way rotation of the impeller drives the clothes to rotate in one direction, so that the detergent can be evenly sprinkled on the clothes. The barrel and the impeller rotate in opposite directions, which can untangle the clothes and prevent the clothes from being tangled and knotted, so that the detergent cannot fully soak the clothes.

[0104] Alternatively, when the washing machine is feeding water and adding detergent, the impeller and the barrel are controlled to rotate in the same direction and in one direction. In this way, the one-way rotation of the impeller drives the clothes to rotate in one direction, so that the detergent can be evenly sprinkled on the clothes. The barrel and the impeller rotate in the same direction, which can effectively reduce the occurrence of clothes entanglement and knotting, so as to further ensure that the detergent is evenly stained on the surface of the clothes.

[0105] Alternatively, the impeller is controlled to rotate in one direction and the barrel body does not rotate. In this way, the impeller rotates in one direction to drive the clothes to rotate in one direction, so that the detergent can be evenly sprinkled on the clothes.

[0106] As an implementation of this embodiment, the preset load weight G 0 , obtain the load weight G in the washing device, and compare the obtained load weight G with the preset load weight G 0 The size of G≥G 0 , then the impeller and the barrel body are controlled to rotate in opposite directions and in one direction; if G<G 0 , then the impeller is controlled to rotate in one direction and the barrel body does not rotate.

[0107] In this embodiment, the obtained load weight G is greater than or equal to the preset load weight G 0 , it means that there is a lot of load in the barrel, that is, there are a lot of clothes. During the rotation of the pulsator, the clothes are easily tangled together. At this time, the pulsator and the barrel are controlled to rotate in opposite and unidirectional directions, so that they can be untangled synchronously during the process of adding detergent to ensure that the clothes can be evenly stained with detergent.

[0108] As an embodiment of the present invention, during the process of water intake and detergent addition into the washing device, the barrel body, or the impeller, or the barrel body and the impeller of the washing device are controlled to rotate unidirectionally, the load weight in the barrel body is obtained, the rotation speed corresponding to the obtained load weight is selected, and the barrel body, the impeller, or the barrel body and the impeller are controlled to rotate unidirectionally at the selected rotation speed.

[0109] More specifically, the controlling step includes:

[0110] S1, water intake begins;

[0111] S2, obtaining the load weight in the barrel;

[0112] S3, selecting a rotation speed corresponding to the acquired load weight;

[0113] S4, controlling the impeller to rotate in one direction according to the selected speed;

[0114] S5, determine whether the water inflow is complete; if so, execute step S6; otherwise, return to step S4;

[0115] S6. End.

[0116] In the present invention, a weight sensor is provided in the barrel of the washing device. In step S2, the weight sensor is controlled to be turned on after the clothes are put in and before the water is introduced, so as to obtain the load weight in the barrel.

[0117] In the present invention, the barrel body and the impeller are controlled to rotate unidirectionally to drive the clothes in the barrel body of the washing device to move in a directional manner. In this way, during the process of adding detergent, the detergent can be evenly sprinkled on the clothes. At the same time, the corresponding unidirectional rotation speed is selected according to the obtained load weight in the barrel body. In this way, the detergent can be evenly stained on the loaded clothes, and the detergent and washing water can separately soak the loaded clothes, thereby improving the washing effect on the clothes.

[0118] As an embodiment of the present invention, selecting the rotation speed corresponding to the acquired load weight includes: acquiring the pre-inlet water level V corresponding to the load weight 0 , and the obtained pre-inlet water level V 0 The corresponding speed is taken as the selected speed.

[0119] Specifically, the control steps include:

[0120] S1, water intake begins;

[0121] S2, obtaining the load weight in the barrel;

[0122] S3. Obtain the pre-inlet water level V corresponding to the load weight. 0 ;

[0123] S4. Select and obtain the pre-inlet water level V 0 The corresponding rotation speed;

[0124] S5, controlling the impeller to rotate in one direction according to the selected speed;

[0125] S6, determine whether the water inflow is complete; if so, execute step S7; otherwise, return to step S5;

[0126] S7. End.

[0127] Preferably, the pre-inlet water level V 0 It is positively correlated with the load weight; that is, the larger the load weight obtained, the more clothes there are in the barrel of the washing device, and the more water is consumed for washing.

[0128] Further preferably, the rotation speed and the pre-inlet water level V 0 A negative correlation.

[0129] In this embodiment, the pre-inlet water level V 0 The higher it is, the more clothes are in the corresponding barrel, and the lower the unidirectional speed is controlled, so that more clothes can be fully soaked by the water flow. Furthermore, the detergent can better adhere to and dissolve on the surface of the soaked clothes.

[0130] As an embodiment of the present invention, the water level V of the essence washing water is preset. 01 , and V 01 <V 0 During the water inlet process, obtain the water level V in the barrel, and compare the obtained water level V with the essence wash water level V 01 If V≤V 01 , then the barrel body and / or the impeller are controlled to rotate in one direction.

[0131] Specifically, the control steps include:

[0132] S1, water intake begins;

[0133] S2, obtaining the load weight in the barrel;

[0134] S3. Obtain the pre-inlet water level V corresponding to the load weight. 0 , preset the water level of essence wash water V 01 ;

[0135] S4, obtaining the water level V in the barrel;

[0136] S5. Determine whether the obtained water inlet level V is less than or equal to the preset essence wash water inlet level V 01 ; If yes, go to step S6, otherwise, go to step S8;

[0137] S6. Select and obtain the pre-inlet water level V 0 The corresponding rotation speed;

[0138] S7, control the impeller to rotate in one direction according to the selected speed, and return to step S5;

[0139] S8: Determine whether the obtained water inlet level V is greater than the pre-water inlet level V 0 ; If yes, go to step S9, otherwise, return to step S5;

[0140] S9, water inflow is completed.

[0141] In this embodiment, when the obtained water inlet level V is less than or equal to the preset essence washing water inlet level V 01When , it indicates that the current water level is low. At this time, it is in the initial stage of water inflow. In this stage, the washing equipment controls the water inflow and the detergent, and controls the barrel and the impeller to rotate in one direction, which helps to spray the detergent evenly on the load surface. At the same time, the speed of the one-way rotation is controlled and the pre-water level V is obtained. 0 Correspondingly, to ensure that the detergent and washing water can fully soak the loaded clothes.

[0142] As an implementation of this embodiment, during the water intake process, the speed of the one-way rotation is controlled to decrease as the water level increases. In this implementation, the water level increases, indicating that the amount of water entering the barrel increases. At this time, the speed of the one-way rotation is controlled to decrease, so that the washing water entering the barrel has enough time to contact the clothes in the barrel, thereby fully soaking the clothes.

[0143] As another implementation of this embodiment, if the water level V in the barrel is greater than the essence wash water level V 01 , the impeller is controlled to execute the forward rotation-pause-reverse timing according to the set cycle, and the forward and reverse rotation speeds of the impeller are higher than the unidirectional rotation speed.

[0144] Specifically, the control steps are as follows:

[0145] S1, water intake begins;

[0146] S2, obtaining the load weight in the barrel;

[0147] S3. Obtain the pre-inlet water level V corresponding to the load weight. 0 , preset the water level of essence wash water V 01 ;

[0148] S4, obtaining the water level V in the barrel;

[0149] S5. Determine whether the obtained water inlet level V is less than or equal to the preset essence wash water inlet level V 01 ; If yes, go to step S6, otherwise, go to step S8;

[0150] S6. Select and obtain the pre-inlet water level V 0 The corresponding rotation speed;

[0151] S7, control the impeller to rotate in one direction according to the selected speed, and return to step S5;

[0152] S8, controlling the impeller to execute the forward rotation-pause-reverse rotation sequence according to the set cycle;

[0153] S9: Determine whether the obtained water inlet level V is greater than the pre-water inlet level V 0 ; If yes, go to step S10, otherwise, return to step S8;

[0154] S10, water intake is completed.

[0155] In this embodiment, if the obtained water inlet level V is greater than the preset essence washing water inlet level V 01 , indicating that the current water intake is large and the detergent has been added. At this time, the pulsator is controlled to execute the forward-pause-reverse timing according to the set cycle to form the washing water in the barrel into forward and reverse water flow, and rub and wash the clothes in the barrel.

[0156] Furthermore, when executing the forward-pause-reverse sequence, the forward and reverse rotation speeds of the impeller are controlled to be higher than the unidirectional rotation speed. This helps to form a stronger forward and reverse water flow, further improving the rubbing and washing effect on the clothes.

[0157] As an implementation mode of this embodiment, controlling the impeller to execute the forward rotation-pause-reverse timing includes: during the water intake process, controlling the forward and reverse rotation speeds of the impeller to increase as the water level increases.

[0158] When executing the forward-pause-reverse sequence, if the water level is low and the speed is too high, the water will flow at high speed in the barrel, causing splashing, which can easily damage clothes and consume a lot of energy; if the water level is high and the speed is too low, a strong and effective washing water flow cannot be formed, and the washing efficiency of clothes is low.

[0159] Based on this, in the control method of this embodiment, as the water level increases, the forward and reverse rotation speeds of the impeller are controlled to increase accordingly so as to form a strong washing water flow. This makes full use of the water flow to wash clothes, improves the washing efficiency of clothes, and the rotation speed corresponding to the water level will not be too high, thereby avoiding damage to clothes.

[0160] As another implementation of this embodiment, controlling the impeller to execute the forward rotation-pause-reverse timing includes: during the water intake process, the rotation time within the set cycle increases with the increase of the water level.

[0161] In this embodiment, the higher the water level, the more water enters the barrel. At this time, the rotation time is controlled to increase so that the clothes are in a rotating state. All areas of the clothes in the rotating state can come into contact with the water flow. That is, increasing the rotation time can make a large amount of washing water in the barrel fully contact with the clothes, so that they can be quickly and efficiently soaked into the clothes.

[0162] As an embodiment of the present invention, the preset water inlet level V 02 , and V 01 <V 02 <V 0 , the control of the impeller to execute the forward rotation-pause-reverse timing includes: during the water inlet process, obtaining the water level V in the barrel, comparing the obtained water level V with the preset water level V 02If V ≥ V 02 , the pause time within the set period of control decreases as the inlet water level increases.

[0163] Specifically, the control steps are as follows:

[0164] S1, water intake begins;

[0165] S2, obtaining the load weight in the barrel;

[0166] S3. Obtain the pre-inlet water level V corresponding to the load weight. 0 , preset the water level of essence wash water V 01 , preset water level V 02 And V 01 <V 02 <V 0 ;

[0167] S4, obtaining the water level V in the barrel;

[0168] S5. Determine whether the obtained water inlet level V is less than or equal to the preset essence wash water inlet level V 01 ; If yes, go to step S6, otherwise, go to step S8;

[0169] S6. Select and obtain the pre-inlet water level V 0 The corresponding rotation speed;

[0170] S7, control the impeller to rotate in one direction according to the selected speed, and return to step S5;

[0171] S8, controlling the impeller to execute the forward rotation-pause-reverse rotation sequence according to the set cycle;

[0172] S9: Determine whether the obtained water inlet level V is greater than or equal to the preset water inlet level V 02 ; If not, go to step S10; If yes, go to step S11;

[0173] S10, the rotation time increases with the increase of the water level, the pause time remains unchanged, and the process returns to step S9;

[0174] S11, the rotation time increases with the increase of the water level, and the pause time decreases with the increase of the water level;

[0175] S12: Determine whether the obtained water inlet level V is greater than the pre-water inlet level V 0 ; If yes, go to step S13, otherwise, return to step S11;

[0176] S13, water intake is completed.

[0177] In this embodiment, if the acquired water level V is greater than or equal to the preset water inlet level V 02And less than the pre-inlet water level V 0 , it means that the detergent has been added and the current water level is high, so the amount of water in the barrel is large. At this time, the pause time in the rotation-stop sequence is shortened, so that the time when the clothes are in the rotating state is prolonged. In this way, the clothes in the rotating state can be more and more fully in contact with a larger amount of washing water, further allowing the washing water to fully penetrate the clothes.

[0178] On the contrary, when the acquired water level V is greater than the preset water inlet level V 01 And less than the pre-inlet water level V 02 It indicates that the detergent has been added, but the water amount in the barrel is moderate. At this time, the rotation time in the control rotation-stop sequence increases with the increase of the water level, and the pause time remains unchanged, which reasonably ensures that the washing water can soak the clothes.

[0179] As another embodiment of the present invention, the water absorption of the load in the washing device is obtained, and the rotation speed of the unidirectional rotation is controlled to be positively correlated with the obtained water absorption.

[0180] Furthermore, obtaining the water absorbency of the load in the washing device includes: obtaining the material of the load, and selecting the water absorbency corresponding to the material as the obtained water absorbency.

[0181] In this embodiment, the greater the water absorbency of the load, the faster the water flow can penetrate into the clothes after contacting the load clothes. Therefore, the speed of the unidirectional rotation is controlled to increase accordingly, which can ensure that the washing water soaks the clothes and improve the soaking efficiency.

[0182] The present invention also provides a washing device, which is controlled by the control method of the present invention. The clothes washed by the washing device of the present invention will not have large color differences in local areas, and the washing effect is good.

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.
