Background Art

[0002] After a washing machine completes a wash cycle, it typically needs to perform a rinse cycle to remove residual detergent and other substances from the clothes. In related solutions, the rinse cycle typically involves filling the inner drum with water to retain it. Once the water level reaches a set rinse level, the inner drum begins operating at a set start-stop ratio, utilizing the remaining water in the drum to rinse the clothes.

[0035] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Consider that in the rinsing cycle of a washing machine in a related solution, the clothes are rinsed using the water stored in the inner drum of the washing machine. However, during this rinsing process, the clothes are always rinsed using the water stored in the inner drum of the washing machine. During each rinse cycle, residual detergent and other substances may come into contact with the clothes again, causing problems such as residual detergent and other substances in the rinse water coming into contact with the clothes again, thereby affecting the rinsing effect of the clothes. In particular, in the late stage of the rinse cycle, after most of the residual detergent and other substances on the clothes have mixed into the rinse water, the already clean clothes will be adsorbed by the residual detergent and other substances, causing secondary contamination of the clothes, thereby affecting the rinsing effect of the clothes.

[0037] Therefore, the solution of the present invention proposes a control method for a washing machine, specifically a spray rinsing control method for a washing machine, by weighing the clothes in the inner drum of the washing machine, and distinguishing the weight levels of the clothes according to the weighing results; distinguishing the speed of the motor of the washing machine according to the weight level of the clothes, so that the motor of the washing machine runs at a speed matching the weight level of the clothes, and spray rinsing and draining are performed at the same time when the motor of the washing machine runs at a speed matching the weight level of the clothes; by using spray rinsing when the speed of the motor of the washing machine matches the weight of the clothes, effective rinsing of the clothes is achieved, which can improve the rinsing effect of the clothes.

[0038] According to an embodiment of the present invention, a method for controlling a washing machine is provided. Figure 1 The washing machine comprises a washing drum and a spraying device 3, wherein the washing drum is an inner drum 2; when the spraying device 3 is turned on, the spraying device 3 sprays water into the interior of the washing drum to form a water curtain.

[0039] In some embodiments, the washing machine further has a door body 1; the spray port of the spray device 3 is located on the inner side above the door body of the washing machine and can spray water into the interior of the washing drum; when the spray device 3 is turned on, the spray device 3 sprays water into the interior of the washing drum through the spray port, the area of ​​the sprayed water can cover the axial area inside the washing drum, and the water column of the sprayed water can form a water curtain.

[0040] Specifically, Figure 6 1 is a schematic structural diagram of an embodiment of a spray device of a washing machine, specifically a right side view of the spray device of the washing machine; Figure 7 FIG1 is a structural diagram of another embodiment of a spray device for a washing machine, specifically a front view of the spray device for a washing machine. Figure 6 and Figure 7 The washing machine shown includes: a door body 1, an inner drum 2, a spray device 3, a water inlet device 4 and a drainage device 5; the water inlet device 4 is arranged at the water inlet of the water inlet pipe of the washing machine, the spray device 3 is arranged at the water outlet of the water inlet pipe of the washing machine, and the drainage device 5 is arranged at the drainage outlet of the drainage pipe of the washing machine.

[0041] like Figure 6 and Figure 7 As shown, the spray device 3 is located at the upper part of the drum opening of the inner drum 2 of the washing machine. When the spray device 3 is turned on, it can spray into the interior of the inner drum 2 of the washing machine; the drainage device 5 is located at the bottom of the inner drum 2 of the washing machine, and water can be discharged from the washing machine through the drainage device 5.

[0042] like Figure 6 and Figure 7As shown, the spray device 3 located above the door 1 of the washing machine sprays toward the inside of the inner drum 2, which can cover the axial area of ​​the inner drum 2 of the washing machine. The water column of the spraying water forms a water curtain with a certain width. After the clothes (such as the clothes 6 in the drum) are close to the drum wall, the inner drum 2 is driven by the motor to rotate. Every time the inner drum 2 rotates, it can be sprayed and rinsed once by the water curtain. Under the action of centrifugal force, the water flow of the spraying water penetrates the clothes attached to the drum wall of the inner drum 2, takes away the residual detergent in the clothes, and the rinsed water is discharged through the drainage device 5. Among them, the axial direction in the axial area of ​​the inner drum 2 refers to the direction perpendicular to the rotation plane of the inner drum 2. Spraying along the axial area can spray and cover the clothes when the inner drum 2 rotates. Figure 6 In the figure, the direction from 3 to 2 is roughly the axial direction. Through the structural design of the sprinkler head, the water column it sprays can form a water curtain along the axial area, similar to the effect of a wall.

[0043] During the rinsing process of the inner drum 2 of the washing machine, residual detergent remains in the inner drum 2 without being discharged, inevitably leading to secondary contamination of the clothes. If a rinsing method is adopted in which the washing machine sprays water while draining water, secondary contamination of the clothes can be effectively avoided. Therefore, the solution of the present invention provides a spray rinsing control scheme for a washing machine, which increases the speed of the washing machine's motor to a certain speed. When the motor drives the inner drum 2 to rotate, the clothes in the inner drum 2 are made to stick to the wall of the inner drum 2. The spray device 3 and the drainage device 5 are turned on at the same time, realizing spray rinsing of the clothes without storing water in the inner drum 2 of the washing machine.

[0044] In the solution of the present invention, Figure 1 As shown, the control method of the washing machine includes: steps S110 to S150.

[0045] In step S110, after the washing program of the washing machine is started and before water is added, the weight of the laundry in the washing tub is obtained and recorded as the laundry weight of the washing machine; the washing program includes: a main wash phase program and a rinse phase program.

[0046] In step S120, after the weight of the laundry in the washing tub is obtained, water is controlled to flow into the washing machine, and the washing machine is controlled to enter the main wash stage and execute the program of the main wash stage.

[0047] At step S130 , after the main wash stage is finished, the washing machine is controlled to enter the rinsing stage and execute the program of the rinsing stage.

[0048] At step S140, during the rinsing stage, the rotation speed of the motor of the washing machine is determined according to the weight of the laundry to be washed, and the current rotation speed of the motor is obtained.

[0049] In some embodiments, in step S140, during the rinsing stage, the rotation speed of the motor of the washing machine is determined according to the weight of the laundry to be washed in the washing machine. The specific process of obtaining the current rotation speed of the motor is described in the following exemplary embodiments.

[0050] The following combination Figure 2 FIG2 is a flow chart of an embodiment of the method of the present invention for determining the current rotational speed of the motor according to the weight of the laundry, further illustrating the specific process of determining the current rotational speed of the motor according to the weight of the laundry in step S140, including steps S210 to S220.

[0051] Step S210: determining the weight level of the laundry in the washing machine within a set weight range, which is recorded as the laundry weight level of the washing machine.

[0052] Step S220 , based on the correspondence between the set weight level and the set motor speed, the set speed corresponding to the set weight level that is the same as the weight level of the laundry in the washing machine in the correspondence is determined as the motor speed corresponding to the weight level of the laundry in the washing machine, as the current speed of the motor.

[0053] Specifically, Figure 8 FIG. 1 is a flow chart of an embodiment of a method for controlling the spraying and rinsing of a washing machine according to the present invention. Figure 8 As shown, a spray rinsing control method of a washing machine of the present invention includes:

[0054] Step 1: After the washing machine's wash cycle is started and before the washing machine's water is added, the washing machine's motor is rotated to weigh the laundry to determine the laundry weight. The laundry weight is then classified into weight levels, such as L1 for smaller amounts of laundry and L2 for larger amounts of laundry. Step 2 is then executed. The magnitude and change of the voltage or current generated by the washing machine's motor during rotation can be used to determine the laundry weight.

[0055] Step 2: Run the main wash process of the washing machine, and then proceed to step 3.

[0056] Step 3: After the main wash cycle is complete, the washing machine enters the spray rinsing phase, i.e., first executing step 31, followed by step 32 or step 33. In the solution of the present invention, there is no need to limit the amount of rinse water, and only one spray rinsing process is performed; spray rinsing is a simultaneous water intake and drainage process, not a water storage rinse, and does not involve heating.

[0057] Step 31 : Determine the rotation speed of the motor of the washing machine (ie, the rotation speed of the inner drum 2 ) according to the laundry weight level determined in step 1 , and then execute step 32 or step 33 .

[0058] As the drum (i.e., inner drum 2) of the washing machine rotates, the clothes will stick to the walls of inner drum 2 as the motor speed increases. For light clothes, a smaller centrifugal force can completely stick to the walls of inner drum 2; for heavy clothes, a larger centrifugal force is required to completely stick to the walls of inner drum 2. The higher the speed of inner drum 2, the greater the centrifugal force generated. Therefore, light clothes can completely stick to the walls of inner drum 2 at a lower speed, while heavy clothes require a higher speed to completely stick to the walls of inner drum 2. Therefore, when executing the spray rinsing stage, after obtaining the weight level of the clothes before the washing water enters, a spray speed that matches the weight level is adopted to achieve the effect of sticking the clothes to the walls of inner drum 2.

[0059] At step S150, during the rinsing phase, the motor is controlled to operate at the determined current speed of the motor to rotate the washing drum, the spray device 3 is controlled to be turned on, and the drain of the washing machine is controlled to be opened. As the washing drum rotates, the laundry to be rinsed within the washing drum adheres to the inner wall of the washing drum. With each rotation of the washing drum, the laundry to be rinsed adhered to the inner wall of the washing drum is rinsed once by the water curtain spray, and the rinsed water is discharged from the drain of the washing machine. Of course, the washing program may also include a spin phase. After the rinsing phase ends, the washing machine is controlled to enter the spin phase and execute the spin phase program until the spin phase ends, completing the washing of the laundry within the washing drum. The inner drum 2 operates at a determined speed, the spray device is turned on, and the drain device is turned on. Preferably, the spray device and drain device are turned on after the speed of the inner drum 2 reaches the determined speed.

[0060] The present invention proposes a spray rinsing control scheme for a washing machine. The scheme weighs the clothes in the inner drum of the washing machine and classifies the weight levels of the clothes according to the weighing results. The scheme also classifies the speed of the washing machine motor according to the weight level of the clothes, so that the washing machine motor runs at a speed that matches the weight level of the clothes. When the washing machine motor runs at a speed that matches the weight level of the clothes, spray rinsing and drainage are performed simultaneously. For example, when the amount of clothes is small (i.e., the weight of the clothes is small), a low speed spray rinsing and drainage are performed; when the amount of clothes is large (i.e., the weight of the clothes is large), a high speed spray rinsing and drainage are performed. In this way, by using spray rinsing when the speed of the washing machine motor matches the weight of the clothes, effective rinsing of the clothes can be achieved, which can improve the rinsing effect of the clothes. Thus, the problem of secondary contamination of clothes by residual detergent in the rinsing water when the water stored in the inner drum of the washing machine is used to rinse clothes is solved, and secondary contamination of clothes by residual detergent during the rinsing process can be effectively avoided.

[0061] In some embodiments, in step S150, during the rinsing phase, controlling the motor to operate at the determined current motor speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain outlet of the washing machine to open includes a control process at a low speed, specifically: if the current motor speed falls within a first set speed range, controlling the motor to operate at the determined current motor speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain outlet of the washing machine to open, until the rinsing phase ends. For example, the first speed range is 80 rpm-150 rpm.

[0062] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention also includes: step 32, if the weight level of the clothes obtained in step 1 is L1, perform low-speed spraying, and the corresponding spray speed is 80rpm-150rpm. Among them, the greater the weight of the clothes, the longer the rinsing time required. For example: when the weight of clothes is divided into four levels of very little, little, medium, and much, the basic spray time corresponding to the very little level is (T) min. On this basis, for each additional level, the spray time is (T+2n) min (n is 0, 1, 2, 3), and the spray time corresponding to the medium-level clothing weight should be (T+4) min. The setting of the spray time T can be specified according to the rated washing capacity of the washing machine. When the rinsing time is completed, stop.

[0063] In some embodiments, in step S150, during the rinsing phase, controlling the motor to operate at the determined current motor speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain outlet of the washing machine to open, further includes: a high speed control process, specifically comprising: during the rinsing phase, if the current motor speed falls within a second set speed range, controlling the motor to operate at the determined current motor speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain outlet of the washing machine to open; wherein the lower limit of the second set speed range is greater than the upper limit of the first set speed range. For example, the second set speed range is 300 rpm-800 rpm.

[0064] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: step 33, if the clothing weight level obtained in step 1 is L2, performing high-speed spraying, and the corresponding spraying speed is 300rpm-800rpm.

[0065] In some embodiments, in step S150, during the rinsing stage, the motor is controlled to operate at the determined current speed of the motor to rotate the washing drum, the spray device 3 is controlled to turn on, and the drain outlet of the washing machine is controlled to open. It also includes: a control process at high speed, specifically also includes: a process of adjusting the status of the spray device 3 and the drain outlet according to the current power of the motor.

[0066] The following combination Figure 3 The flowchart of an embodiment of adjusting the state of the spray device 3 and the drain outlet according to the current power of the motor in the method of the present invention further illustrates the specific process of adjusting the state of the spray device 3 and the drain outlet according to the current power of the motor in step S150, including: steps S310 to S320.

[0067] In step S310, during the rinsing phase, if the current speed of the motor falls within the second set speed range, after controlling the motor to operate at the determined current speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain port of the washing machine to open for a set time, the current power of the motor, i.e., the operating power of the motor, is determined. For example, the operating power of the motor can be determined by detecting the voltage and current of the motor during operation.

[0068] Step S320, during the rinsing stage, the opening and closing of the spray device 3 is controlled according to the current power of the motor, the drain outlet of the washing machine is kept open, and the motor is kept running at the determined current speed of the motor to rotate the washing drum until the rinsing stage ends.

[0069] In the solution of the present invention, the speed of the inner drum 2 of the washing machine is differentiated by the weight of the clothes in the inner drum 2, such as distinguishing between high speed operation of the inner drum 2 and low speed operation of the inner drum 2; and whether the inner drum 2 is running at high speed or low speed, the operation is carried out under the condition that the spray device 3 (such as the spray valve 3) is turned on. However, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: in step 33, when performing high-speed spraying, the operating power of the motor is detected in real time; when the power of the motor is too high, it is necessary to control the opening and closing of the spray device 3 according to the power of the motor.

[0070] In some embodiments, in step S320, during the rinsing stage, the specific process of controlling the opening and closing of the spray device 3 according to the current power of the motor is described in the following exemplary embodiment.

[0071] The following combination Figure 4 The flowchart of an embodiment of controlling the opening and closing of the spray device 3 according to the current power of the motor in the method of the present invention further illustrates the specific process of controlling the opening and closing of the spray device 3 according to the current power of the motor in step S320, including: steps S410 to S430.

[0072] Step S410: During the rinsing stage, determining whether the current power of the motor is higher than a set power threshold.

[0073] Step S420: During the rinsing stage, if it is determined that the current power of the motor is not higher than the set power threshold, the spray device 3 is kept turned on.

[0074] In step S430, during the rinsing phase, if it is determined that the current power of the motor is higher than the set power threshold, the spray device 3 is controlled to be turned off until the current power of the motor is lower than the set power threshold. The spray device 3 is then controlled to be turned on again, and this cycle is repeated until the rinsing phase ends. In other words, during the high-speed rinsing process, the current power of the motor is monitored in real time or at regular intervals, and the opening and closing of the spray device 3 is controlled based on the current power of the motor until the rinsing phase ends.

[0075] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: in step 33, when performing high-speed spraying, real-time detection of the operating power of the motor; when the power of the motor is too high, closing the spray device 3 and keeping the drainage device 5 open; after detecting that the motor power has stabilized, reopening the spray device 3.

[0076] Referring to the example shown in steps 31, 32, and 33, as the clothes rotate within inner drum 2, they will cling to the walls of inner drum 2 at a certain speed. When the load is light, inner drum 2 can run at a lower speed (e.g., above 80 rpm) to ensure the clothes cling to the walls. However, when the load is heavy, inner drum 2 must run at a higher speed to ensure the clothes cling to the walls. When the clothes cling to the walls of inner drum 2, a cavity is formed within the drum, allowing spray to enter the drum through the spray port, ensuring a uniform rinse. Therefore, by using different speeds for spraying based on the weight of the clothes, this allows for quicker spraying of the clothes against the walls of inner drum 2, reducing time and energy consumption (increasing motor speed requires time and also increases energy consumption). For larger loads, this ensures a consistent rinse effect and achieves more precise rinse control.

[0077] The technical solution of this embodiment is adopted, by arranging a spray device on the inner side above the door body of the washing machine, when the spray device is turned on, it can spray water into the axial area inside the washing drum (i.e., the inner drum 2) of the washing machine to form a water curtain; after the washing program of the washing machine is started and before water is added, the weight of the clothes in the washing drum of the washing machine is first obtained, then water is added and the washing program is executed, and a spray rinsing stage is performed after the washing program is completed, and dehydration is completed after the spray rinsing stage is completed; in the spray rinsing stage, after the spray device and the drainage device of the washing machine are turned on, the speed of the motor of the washing machine is determined according to the weight of the clothes obtained before water is added, the motor of the washing machine is controlled to drive the washing drum to rotate at the determined speed, and the opening and closing of the spray device and the drainage device are further controlled until the spray rinsing stage is completed; thus, by adopting the method of spraying and draining at the same time during the rinsing process, and making the motor run at a speed matching the weight of the clothes before water is added, the rinsing effect of the clothes can be improved.

[0078] According to an embodiment of the present invention, a control device for a washing machine corresponding to the control method for a washing machine is also provided. Figure 5 The schematic structural diagram of an embodiment of the device of the present invention is shown. The washing machine comprises a washing drum and a spray device 3, wherein the washing drum is an inner drum 2; when the spray device 3 is turned on, the spray device 3 sprays water into the interior of the washing drum to form a water curtain.

[0079] In some embodiments, the washing machine further has a door body 1; the spray port of the spray device 3 is located on the inner side above the door body of the washing machine and can spray water into the interior of the washing drum; when the spray device 3 is turned on, the spray device 3 sprays water into the interior of the washing drum through the spray port, the area of ​​the sprayed water can cover the axial area inside the washing drum, and the water column of the sprayed water can form a water curtain.

[0080] Specifically, Figure 6 1 is a schematic structural diagram of an embodiment of a spray device of a washing machine, specifically a right side view of the spray device of the washing machine; Figure 7 FIG1 is a structural diagram of another embodiment of a spray device for a washing machine, specifically a front view of the spray device for a washing machine. Figure 6 and Figure 7 The washing machine shown includes: a door body 1, an inner drum 2, a spray device 3, a water inlet device 4 and a drainage device 5; the water inlet device 4 is arranged at the water inlet of the water inlet pipe of the washing machine, the spray device 3 is arranged at the water outlet of the water inlet pipe of the washing machine, and the drainage device 5 is arranged at the drainage outlet of the drainage pipe of the washing machine.

[0081] like Figure 6 and Figure 7 As shown, the spray device 3 is located at the upper part of the drum opening of the inner drum 2 of the washing machine. When the spray device 3 is turned on, it can spray into the interior of the inner drum 2 of the washing machine; the drainage device 5 is located at the bottom of the inner drum 2 of the washing machine, and water can be discharged from the washing machine through the drainage device 5.

[0082] like Figure 6 and Figure 7 As shown, a spray device 3 located above the washing machine door 1 sprays water into the interior of the inner drum 2, covering the entire axial area of ​​the inner drum 2. The spray water forms a water curtain of a certain width. After clothing (such as clothing 6) is placed against the drum wall, the inner drum 2 rotates driven by the motor. Each rotation of the inner drum 2 is rinsed by the water curtain. Centrifugal force causes the spray water to penetrate the clothing adhered to the inner drum 2 wall, removing any residual detergent. The rinse water is then discharged through the drain device 5.

[0083] During the rinsing process of the inner drum 2 of the washing machine, residual detergent remains in the inner drum 2 without being discharged, inevitably leading to secondary contamination of the clothes. If a rinsing method is adopted in which the washing machine sprays water while draining water, secondary contamination of the clothes can be effectively avoided. Therefore, the solution of the present invention provides a spray rinsing control scheme for a washing machine, which increases the speed of the washing machine's motor to a certain speed. When the motor drives the inner drum 2 to rotate, the clothes in the inner drum 2 are made to stick to the wall of the inner drum 2. The spray device 3 and the drainage device 5 are turned on at the same time, realizing spray rinsing of the clothes without storing water in the inner drum 2 of the washing machine.

[0084] In the solution of the present invention, Figure 5 As shown, the control device of the washing machine includes: an acquisition unit 102 and a control unit 104.

[0085] The acquisition unit 102 is configured to acquire the weight of the laundry in the washing drum after the washing machine starts a wash cycle and before water is added, and record this as the laundry weight of the washing machine. The washing cycle includes a main wash phase and a rinse phase. The specific functions and processing of the acquisition unit 102 are described in step S110.

[0086] The control unit 104 is configured to control the water supply to the washing machine after obtaining the weight of the laundry in the washing tub, control the washing machine to enter the main wash phase and execute the main wash phase program. The specific functions and processing of the control unit 104 are shown in step S120.

[0087] The control unit 104 is further configured to control the washing machine to enter the rinsing stage and execute the rinsing stage program after the main wash stage is completed. The specific functions and processing of the control unit 104 are also shown in step S130.

[0088] The control unit 104 is further configured to determine the rotation speed of the motor of the washing machine according to the weight of the laundry in the washing machine during the rinsing phase to obtain the current rotation speed of the motor. The specific functions and processing of the control unit 104 are further described in step S140.

[0089] In some embodiments, the control unit 104 determines the rotational speed of the motor of the washing machine according to the weight of the laundry in the washing machine during the rinsing phase, and obtains the current rotational speed of the motor, including:

[0090] The control unit 104 is further configured to determine the weight level of the laundry in the washing machine within a set weight range, which is recorded as the laundry weight level of the washing machine. Specific functions and processing of the control unit 104 are also described in step S210.

[0091] The control unit 104 is further configured to, based on the correspondence between the set weight levels and the set motor speeds, determine the set speed corresponding to the set weight level that is equal to the laundry weight level of the washing machine as the motor speed corresponding to the laundry weight level of the washing machine, as the current motor speed. The specific functions and processing of the control unit 104 are further described in step S220.

[0092] Specifically, Figure 8 FIG. 1 is a flow chart of an embodiment of a method for controlling the spraying and rinsing of a washing machine according to the present invention. Figure 8 As shown, a spray rinsing control method of a washing machine of the present invention includes:

[0093] Step 1: After the washing program of the washing machine is started and before the washing water is added, the clothes are weighed by rotating the motor of the washing machine to obtain the weight of the clothes; the clothes are classified into weight levels according to the weight of the clothes, such as less clothes corresponding to clothes weight level L1, and more clothes corresponding to clothes weight level L2, and then step 2 is executed.

[0094] Step 2: Run the main wash process of the washing machine, and then proceed to step 3.

[0095] Step 3: After the main wash cycle is complete, the washing machine enters the spray rinsing phase, i.e., first executing step 31, followed by step 32 or step 33. In the solution of the present invention, there is no need to limit the amount of rinse water, and only one spray rinsing process is performed; spray rinsing is a simultaneous water intake and drainage process, not a water storage rinse, and does not involve heating.

[0096] Step 31 : Determine the rotation speed of the motor of the washing machine (ie, the rotation speed of the inner drum 2 ) according to the laundry weight level determined in step 1 , and then execute step 32 or step 33 .

[0097] As the drum (i.e., inner drum 2) of the washing machine rotates, the clothes will stick to the walls of inner drum 2 as the motor speed increases. For light clothes, a smaller centrifugal force can completely stick to the walls of inner drum 2; for heavy clothes, a larger centrifugal force is required to completely stick to the walls of inner drum 2. The higher the speed of inner drum 2, the greater the centrifugal force generated. Therefore, light clothes can completely stick to the walls of inner drum 2 at a lower speed, while heavy clothes require a higher speed to completely stick to the walls of inner drum 2. Therefore, when executing the spray rinsing stage, after obtaining the weight level of the clothes before the washing water enters, a spray speed that matches the weight level is adopted to achieve the effect of sticking the clothes to the walls of inner drum 2.

[0098] The control unit 104 is further configured to, during the rinsing phase, control the motor to operate at the determined current speed of the motor to rotate the washing drum, control the spray device 3 to turn on, and control the drain of the washing machine to open. As the washing drum rotates, the laundry to be rinsed within the washing drum adheres to the inner wall of the washing drum. With each rotation of the washing drum, the laundry to be rinsed adheres to the inner wall of the washing drum by the water curtain spray, and the rinsed water is discharged from the drain of the washing machine. Of course, the washing program may also include a spin phase. After the rinsing phase ends, the washing machine is controlled to enter the spin phase and execute the spin phase program until the spin phase ends, completing the washing of the laundry within the washing drum. The specific functions and processing of the control unit 104 are further described in step S150.

[0099] The present invention proposes a spray rinsing control scheme for a washing machine. The scheme weighs the clothes in the inner drum of the washing machine and classifies the weight levels of the clothes according to the weighing results. The scheme also classifies the speed of the washing machine motor according to the weight level of the clothes, so that the washing machine motor runs at a speed that matches the weight level of the clothes. When the washing machine motor runs at a speed that matches the weight level of the clothes, spray rinsing and drainage are performed simultaneously. For example, when the amount of clothes is small (i.e., the weight of the clothes is small), a low speed spray rinsing and drainage are performed; when the amount of clothes is large (i.e., the weight of the clothes is large), a high speed spray rinsing and drainage are performed. In this way, by using spray rinsing when the speed of the washing machine motor matches the weight of the clothes, effective rinsing of the clothes can be achieved, which can improve the rinsing effect of the clothes. Thus, the problem of secondary contamination of clothes by residual detergent in the rinsing water when the water stored in the inner drum of the washing machine is used to rinse clothes is solved, and secondary contamination of clothes by residual detergent during the rinsing process can be effectively avoided.

[0100] In some embodiments, the control unit 104 controls the motor to operate at the determined current speed of the motor to rotate the washing tub, controls the spray device 3 to turn on, and controls the drain outlet of the washing machine to open during the rinsing phase, including a control process at a low speed, specifically, the control unit 104 is further configured to, during the rinsing phase, if the current speed of the motor falls within a first set speed range, control the motor to operate at the determined current speed of the motor to rotate the washing tub, controls the spray device 3 to turn on, and controls the drain outlet of the washing machine to open, until the rinsing phase ends. For example, the first speed range is 80 rpm-150 rpm.

[0101] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: step 32, if the clothing weight level obtained in step 1 is L1, performing low speed spraying, and the corresponding spraying speed is 80rpm-150rpm.

[0102] In some embodiments, the control unit 104 controls the motor to operate at the determined current speed of the motor to rotate the washing tub, controls the spray device 3 to turn on, and controls the drain outlet of the washing machine to open during the rinsing phase. The control process at high speed specifically includes: the control unit 104 is further configured to control the motor to operate at the determined current speed of the motor to rotate the washing tub, controls the spray device 3 to turn on, and controls the drain outlet of the washing machine to open during the rinsing phase if the current speed of the motor falls within a second set speed range; wherein the lower limit of the second set speed range is greater than the upper limit of the first set speed range. For example, the second set speed range is 300 rpm-800 rpm.

[0103] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: step 33, if the clothing weight level obtained in step 1 is L2, performing high-speed spraying, and the corresponding spraying speed is 300rpm-800rpm.

[0104] In some embodiments, the control unit 104 controls the motor to operate at the determined current speed of the motor to rotate the washing drum, controls the spray device 3 to turn on, and controls the drain outlet of the washing machine to open during the rinsing phase. The control process at high speed also includes a process of adjusting the states of the spray device 3 and the drain outlet according to the current power of the motor, as follows:

[0105] The control unit 104 is further configured to, during the rinsing phase, determine the current power of the motor, i.e., the operating power of the motor, after controlling the motor to operate at the determined current speed to rotate the washing tub, controlling the spray device 3 to turn on, and controlling the drain port of the washing machine to open for a set time, if the current speed of the motor falls within the second set speed range. For example, the operating power of the motor can be determined by detecting the voltage and current of the motor during operation. The specific functions and processing of the control unit 104 are further described in step S310.

[0106] The control unit 104 is further configured to, during the rinsing phase, control the opening and closing of the spray device 3 based on the current power of the motor, maintain the drain opening of the washing machine open, and maintain the motor running at the determined current speed to rotate the washing tub until the rinsing phase ends. The specific functions and processing of the control unit 104 are further described in step S320.

[0107] In the solution of the present invention, the speed of the inner drum 2 of the washing machine is differentiated by the weight of the clothes in the inner drum 2, such as distinguishing between high speed operation of the inner drum 2 and low speed operation of the inner drum 2; and whether the inner drum 2 is running at high speed or low speed, the operation is carried out under the condition that the spray device 3 (such as the spray valve 3) is turned on. However, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: in step 33, when performing high-speed spraying, the operating power of the motor is detected in real time; when the power of the motor is too high, it is necessary to control the opening and closing of the spray device 3 according to the power of the motor.

[0108] In some embodiments, the control unit 104 controls the opening and closing of the spray device 3 according to the current power of the motor during the rinsing stage, including:

[0109] The control unit 104 is further configured to determine whether the current power of the motor is higher than a set power threshold during the rinsing phase. The specific functions and processing of the control unit 104 are further described in step S410.

[0110] The control unit 104 is further configured to keep the spray device 3 turned on if it is determined that the current power of the motor is not higher than the set power threshold during the rinsing phase. The specific functions and processing of the control unit 104 are also shown in step S420.

[0111] The control unit 104 is further configured to, during the rinsing phase, control the spray device 3 to be turned off if it determines that the current power of the motor is higher than a set power threshold. This control unit 104 will control the spray device 3 to be turned off until the current power of the motor falls below the set power threshold. It will then control the spray device 3 to be turned on again, and this cycle will continue until the rinsing phase ends. In other words, during the high-speed rinsing process, the current power of the motor is monitored in real time or at regular intervals, and the spray device 3 is controlled to be turned on and off based on the current power of the motor until the rinsing phase ends. The specific functions and processing of the control unit 104 are further described in step S430.

[0112] Specifically, if Figure 8 As shown, a spray rinsing control method for a washing machine of the present invention further includes: in step 33, when performing high-speed spraying, real-time detection of the operating power of the motor; when the power of the motor is too high, closing the spray device 3 and keeping the drainage device 5 open; after detecting that the motor power has stabilized, reopening the spray device 3.

[0113] Referring to the example shown in steps 31, 32, and 33, as the clothes rotate within inner drum 2, they will cling to the walls of inner drum 2 at a certain speed. When the load is light, inner drum 2 can run at a lower speed (e.g., above 80 rpm) to ensure the clothes cling to the walls. However, when the load is heavy, inner drum 2 must run at a higher speed to ensure the clothes cling to the walls. When the clothes cling to the walls of inner drum 2, a cavity is formed within the drum, allowing spray to enter the drum through the spray port, ensuring a uniform rinse. Therefore, by using different speeds for spraying based on the weight of the clothes, this allows for quicker spraying of the clothes against the walls of inner drum 2, reducing time and energy consumption (increasing motor speed requires time and also increases energy consumption). For larger loads, this ensures a consistent rinse effect and achieves more precise rinse control.

After the washing program of the washing machine is started and before water is added, the weight of the clothes in the washing drum of the washing machine is first obtained, and then water is added and the washing program is executed. After the washing program is completed, a spray rinsing stage is performed, and dehydration is completed after the spray rinsing stage is completed. In the spray rinsing stage, after the spray device and the drain device of the washing machine are turned on, the speed of the motor of the washing machine is determined according to the weight of the clothes obtained before water is added, the motor of the washing machine is controlled to drive the washing drum to rotate at the determined speed, and the opening and closing of the spray device and the drain device are further controlled until the spray rinsing stage is completed. By distinguishing the weight of the clothes, different speeds are used for spraying. In the case of a small amount of clothes, spraying can be quickly achieved by sticking to the wall of the inner drum 2 to reduce time and energy consumption. In the case of a large amount of clothes, the rinsing effect can be guaranteed.
