[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The reason why the washing machine door is not completely closed may be that the clothes are caught between the door and the door frame when the user puts the clothes in, or the clothes are stuck to the door during the washing process. And if the clothes are caught, they will be pulled as the drum rotates, causing the clothes and the door seal to wear and cause damage to the clothes.

[0031] Therefore, the present invention provides a control method for a washing machine. When the door is not completely closed, the reason why the door is not completely closed is determined according to the current step of the washing program, and different controls and reminders are performed, thereby preventing the washing machine from leaking and affecting the user experience, and preventing clothes from being caught and damaged, making the washing machine more intelligent and improving the user experience.

[0032] According to an embodiment of the present invention, a control method for a washing machine is provided, wherein the washing machine comprises a door, a door seal, a spray component, and a drum; a sensor is provided at the bottom of a clothing inlet of the washing machine; the sensor is used to detect whether there is water at the bottom of the clothing inlet; the door seal is provided at the edge of the clothing inlet, and is used to cooperate with the door seal; the spray component can rinse the door and the door seal, and the rinsed water will pass through the sensor.

[0033] The washing machine is a drum washing machine, and the clothing loading port is located on the front of the washing machine. Figure 3 As shown, the clothing inlet is circular and located at the center of the front of the washing machine. The door 1 has the same shape as the clothing inlet and can completely cover the clothing inlet. A door seal is provided on the frame of the clothing inlet. When the door is closed, the door can cooperate with the door seal to make the interior of the washing machine a closed area. The door seal is made of rubber to prevent water leakage.

[0034] A sensor is provided at the bottom of the clothing loading port, which can detect whether there is water. Figure 3 As shown, a sensor 2 is arranged just below the central axis of the clothing inlet. The sensor can be a temperature sensor, which detects by using the characteristic that the temperature changes when water flows through; the sensor can also be a weak current conductor, which detects whether water flows through by using the inductive coupling method. Specifically, a cover full of mesh holes can be placed just below the central axis of the clothing inlet, a super-hydrophobic coating is sprayed under the cover, and the sensor is arranged under the cover. The super-hydrophobic coating is added to allow water to flow through here quickly without accumulating water, thereby improving the accuracy of the sensor in detecting water leakage in the washing machine.

[0035] The spray component is located inside the washing machine. When the door is closed, the spray component can wash the inner surface of the door and the door seal. When the door is completely closed, the washing water will not flow to the sensor position; when the door is not completely closed, the washing water will flow from the door gap to the sensor position due to gravity and be detected by the sensor.

[0036] When the user puts clothes into the washing machine through the door and closes the door, if the clothes are not caught by the door, the door and the door seal fit perfectly, and the water in the washing machine will not leak out of the door, that is, no water will flow through the sensor. If the clothes are caught by the door, a gap will form between the door and the door seal, and the water in the washing machine will leak out of the door; or when the washing machine is running, the door is lifted up by the clothes, causing water leakage, and due to the effect of gravity, water will leak out from the location of the sensor, so that the sensor detects that there is water at the bottom of the clothing inlet.

[0037] like Figure 1The flowchart of an embodiment of the method of the present invention is shown in FIG. The control method of the washing machine may include: steps S110 to S140.

[0038] In step S110, after the washing machine starts to execute the washing program, the detection result of the sensor and the current washing steps are obtained; the washing steps are the steps included in the washing program.

[0039] In some embodiments, the laundry program includes the following steps in sequence: a washing step, a washing and dehydration step, a rinsing step, a rinsing and dehydration step, and a final dehydration step.

[0040] In step S120, the spray component is controlled to operate according to the current washing step.

[0041] In some embodiments, in step S120, the specific process of controlling the operation of the spray component according to the current washing step includes: when the current washing step proceeds to the washing step, before washing, controlling the spray component to operate. Alternatively, when the current washing step proceeds to the final dehydration, controlling the spray component to operate before and after the final dehydration.

[0042] In the washing program, the spray component is combined, and the final washing steps can be: detecting the water level in the barrel, rinsing the machine door, weighing, washing, washing and dehydrating, rinsing, rinsing and dehydrating, the last rinse, rinsing the machine door, final dehydration, rinsing the machine door, shaking the clothes. Among them, when detecting the water level in the barrel, if the water level in the barrel is high, drain it, and if the water level is low, proceed to the next step. Weighing is to weigh the clothes in the barrel, so as to select the appropriate parameters such as the water intake. The number of rinses can be set according to the actual situation. Usually the machine door is made of transparent material, which is convenient for users to observe the situation in the barrel.

[0043] When the spray component is controlled to work to flush the machine door, a flushing time is preset. When the working time of the spray component reaches the flushing time, the spray component stops working and the washing machine executes the next step.

[0044] After the final spin, there may be foam left on the door and door seal. Rinsing the door at this time may wash the foam onto the clothes. Therefore, rinse the door before the final spin to minimize the foam on the clothes. Rinsing the door after the final spin is used to clean the door and door seal.

[0045] The flushing door before weighing is used to determine whether the external environment affects the sensor's detection results according to the sensor's detection results during the flushing process. Specifically, since the water level in the tub has been drained below the preset water level in the tub water level detection step, the water in the tub will not pass through the sensor position. At this time, if water in the external environment penetrates into the sensor from the door seal, it will affect the subsequent judgment of whether the washing machine is leaking, making the judgment inaccurate.

[0046] In some embodiments, the method further includes a process of determining whether the detection result of the sensor is accurate before the washing machine starts to execute the washing program, and the process specifically includes: determining whether there is water at the bottom of the clothing inlet according to the detection result of the sensor before the washing machine starts to execute the washing program; if there is water at the bottom of the clothing inlet, then during the current washing program of the washing machine, the washing machine is no longer detected for water leakage. If there is no water at the bottom of the clothing inlet, then during the current washing program of the washing machine, the spray component is controlled to work according to the current washing step, and when it is determined that the washing machine is leaking, the start and stop of the washing machine and the speed of the drum are controlled according to the current washing step.

[0047] Before the washing machine starts the washing program and weighs, the water in the barrel has been drained and no water will pass through the sensor position. If the sensor detects water at the bottom of the door frame, it is considered that water in the external environment has penetrated into the sensor position. Therefore, it is impossible to accurately determine whether there is a water leak in the washing machine based on the sensor's detection results, and it is impossible to determine whether the door is not closed tightly. At this time, the app and the whole machine will prompt that the washing machine will no longer be detected for water leakage during this washing process, and the washing machine will run to the end according to the washing program. Conversely, if the sensor detects that there is no water at the bottom of the door frame, it means that the sensor's detection can accurately determine whether the washing machine is leaking. Therefore, when the washing machine runs according to the washing program, it is determined whether the washing machine is leaking based on the current washing steps and the sensor's detection results, and the working state of the washing machine is controlled to make the washing machine more intelligent.

[0048] In step S130, it is determined whether the washing machine is leaking water according to the detection result of the sensor, and specifically, it is determined whether the door is leaking water due to the door not being closed tightly.

[0049] In some embodiments, in step S130, the specific process of determining whether the washing machine is leaking according to the detection result of the sensor includes: determining whether there is water at the bottom of the clothing inlet according to the detection result of the sensor; if it is determined that there is water at the bottom of the clothing inlet, it is determined that the washing machine is leaking; if it is determined that there is no water at the bottom of the clothing inlet, it is determined that the washing machine is not leaking.

[0050] Because it has been determined that the external environment will not affect the accuracy of the sensor in judging whether the washing machine is leaking before the washing program is started, it is believed that whether there is water at the bottom of the clothing inlet can indicate whether the washing machine is leaking.

[0051] At step S140, if it is determined that the washing machine is leaking, the working state of the washing machine and the speed of the drum are controlled according to the current washing step. The working state of the washing machine includes starting and stopping the washing machine, switching different washing programs, skipping a step in the washing program, and sending a message prompt.

[0052] When the sensor detects water during the operation of the washing machine, it may be that the water inside the washing machine has leaked out, or that the water outside the washing machine has penetrated from the door seal to the sensor position. Therefore, it is not accurate to judge whether the washing machine is leaking based on the sensor's detection results alone. Because this solution combines the washing step of the washing machine and the sensor's detection results to more accurately judge whether the washing machine is leaking; at the same time, the working state of the washing machine is controlled according to the degree of the leakage, avoiding the washing machine being shut down as soon as a leakage is detected, which affects the user experience, making the washing machine more intelligent.

[0053] In some embodiments, in step S140, the specific process of controlling the working state of the washing machine and the rotation speed of the drum according to the current washing step includes: if the current washing step proceeds to the washing step and the spray component is in a working state, the washing machine is controlled to stop executing the washing program, and the washing machine is controlled to issue a prompt message that the clothes are clamped by the door.

[0054] The door is rinsed before weighing and washing to determine whether the door is completely closed and whether it is leaking. Specifically, during the door rinse process, when the sensor detects water at the bottom of the clothing inlet, it is considered that the door is leaking, which may be caused by the door clamping the clothes and causing the door to not be completely closed. At this time, the washing machine is controlled to stop washing and a prompt message is issued that the door is clamping the clothes and the door is leaking. When the sensor detects that there is no water, it is considered that the door is not clamping the clothes and there is no leakage, and the washing machine continues to execute the washing program.

[0055] In some embodiments, in step S140, the specific process of controlling the working state of the washing machine and the rotational speed of the drum according to the current washing step also includes: if the current washing step proceeds to the washing step or the rinsing step, obtaining the weight of the clothes in the washing machine; judging the relationship between the weight of the clothes and a preset weight; if the weight of the clothes is greater than the preset weight, controlling the washing machine to execute a preset unwinding program; or controlling the washing machine to skip the current washing step and continue to execute the washing program; if the weight of the clothes is less than or equal to the preset weight, controlling the washing machine to continue to execute the washing program and reduce the rotational speed of the drum.

[0056] The weight of the clothes in the washing machine is determined by weighing. The preset untangling program is used to solve the problem of clothes tangling. During the washing and rinsing process, there is a lot of water in the barrel and the barrel is always rotating, so the clothes may be twisted and leak. Specifically, when the weight of the clothes is greater than the preset weight, it is considered that the washing machine is under medium or high load. In this case, it is more likely that the clothes are twisted and the top door is twisted. Therefore, it is determined that the clothes are twisted and the top door is twisted. At this time, the untangling program is executed, or the current step is skipped to wash and drain or rinse and dehydrate, thereby alleviating the situation of the clothes top door. It should be noted that when the clothes top door leaks, a stall signal that the motor cannot rotate often appears at the same time. At this time, skipping the current step and entering the next step can reduce the number of fault reports and enable the washing program to be fully executed. When the weight of the clothes is less than the preset weight, it is considered that there are fewer clothes in the barrel and the clothes top door will not appear. Therefore, it is considered that the external environment has changed suddenly, or the whole machine has structural damage. At this time, the rhythm of washing is slowed down, and the rotation speed of the drum is reduced to prevent excessive foam from leaking from the washing machine to the room.

[0057] In some embodiments, in step S140, the specific process of controlling the working state of the washing machine and the rotation speed of the drum according to the current washing step also includes: if the current washing step proceeds to the washing and dehydration step or the rinsing and dehydration step, controlling the washing machine to continue executing the washing program.

[0058] During washing and dehydration and rinsing and dehydration, if the sensor detects water leakage, it is considered that the clothes are entangled in the top door. During the washing and dehydration and rinsing and dehydration process, the speed of the drum is low, usually not exceeding 400 revolutions. At low speeds, the entangled clothes will stick to the inner wall of the drum, and the clothes will not hit the top door, and there will be no displacement from hitting the drum. After dehydration, the position of the clothes will be disrupted, and the phenomenon of clothes entangled in the top door will be reduced. Therefore, when the sensor detects water leakage during the washing and dehydration and rinsing and dehydration steps, the washing machine executes the washing program normally.

[0059] In some embodiments, in step S140, the specific process of controlling the working state of the washing machine and the rotation speed of the drum according to the current washing step also includes: if the step in which the washing machine is located reaches the final dehydration step, controlling the washing machine to continue to execute the washing program; and in the final dehydration step, controlling the drum to run at a first rotation speed for a first time, and then controlling the drum to run at a second rotation speed for a second time; the first rotation speed < the second rotation speed.

[0060] During the final spin, if the sensor detects a leak, it is considered that the clothes are entangled with the top door. Usually the rotation speed of the drum is relatively high during the final spin. Therefore, in order to solve the problem of clothes entangled with the top door, a low-speed pre-spin is added during the final spin, and the maximum rotation speed of the final spin is reduced. That is, the final spin is divided into two stages. The first stage is a low-speed pre-spin, and the rotation speed of the low-speed pre-spin is a lower first rotation speed. The second stage is the final spin, and the final spin is a higher second rotation speed, and the second rotation speed is less than the preset maximum rotation speed during the final spin. By adding a low-speed pre-spin stage and reducing the maximum rotation speed of the spin, the clothes are kept close to the inner wall of the drum at a low speed, which alleviates the problem of clothes hitting the top door.

[0061] If the sensor detects a water leak during the final spin speed reduction stage, or during the door rinsing stage after the final spin, it is considered that the sensor detected the water leak due to a change in the external environment or structural damage to the washing machine. Since the washing program is about to end at this time and no water is entering the barrel, no action is taken.

[0062] Figure 4 The flowchart of another embodiment of the control method of the washing machine of the present invention comprises:

[0063] Step 1: After the washing machine door is closed, the washing program is started, and the sensor detects whether water is continuously flowing through. If water is detected to be continuously flowing through, the whole machine and the app will prompt, and the washing machine will continue to run the washing program. If no water is detected to be flowing through, the clothes will be weighed and step 2 will be executed.

[0064] Step 2: The spray pipe rinses the glass bowl and door seal of the machine door. During this process, the sensor detects whether water is continuously flowing through. If water is detected to be continuously flowing through, the washing process is suspended and an alarm is issued to the user, indicating that clothing may be caught in the machine door. If no water is detected to be flowing through, the washing process continues and step 3 is performed.

[0065] Step 3, the sensor continues to detect whether water is passing through. If the sensor continues to detect water passing through, if it is in the washing or rinsing stage, then execute step 4; if it is in the washing and dehydration or rinsing and dehydration stage, then control the washing machine to continue the washing program and re-execute step 3; if it is in the final dehydration or shaking stage, then execute step 5; if it is in the dehydration speed reduction stage of the final dehydration, it is considered that the whole machine is structurally damaged or the external environment has changed, and the washing machine is controlled to continue the washing program until it ends. If no water is detected passing through, then control the washing machine to continue the washing program until it ends.

[0066] Step 4, determine whether the load weight level in the washing machine is medium or multi-load. If the load weight level is medium or multi-load, it is determined that the clothes are entangled and twisted, and the top door is leaking. At this time, the untwisting process is run, and then the water is drained to the door opening water level, and the next washing stage is continued, and step 3 is re-executed. If the load weight level is light load, it is considered to be a false detection or structural damage of the whole machine or a change in the external environment. At this time, the washing rotation rhythm is reduced and the machine is operated to the next stage, or a fault is reported due to structural damage, and step 3 is re-executed.

[0067] Step 5: It is determined that the clothes are stuck between the door seals, or the clothes are seriously entangled and hit the door. Add a low-speed pre-spin during the final spin cycle and lower the maximum speed setting. If it is the shaking stage, no processing is done and the washing process continues until the end.

[0068] The technical solution of this embodiment is adopted, a spray component for washing the machine door and door seal is set in the washing machine, and a sensor for detecting whether there is water is set at the clothing loading port; after the washing machine starts to execute the washing program, the spray component is controlled to work according to the washing steps of the current washing program, and whether the washing machine is leaking is determined according to the detection result of the sensor; if it is determined to be leaking, the working state of the washing machine and the speed of the drum of the washing machine are controlled according to the current washing steps. In this way, the user is prevented from being affected by the leakage of the washing machine, and the washing process is carried out as completely as possible, making the washing machine more intelligent and improving the user experience.

The washing machine comprises a machine door, a door seal, a spray component, and a drum; a sensor is arranged at the bottom of the clothing inlet of the washing machine; the sensor is used to detect whether there is water at the bottom of the clothing inlet; the door seal is arranged at the edge of the clothing inlet, and is used to cooperate with the machine door seal; the spray component can rinse the machine door and the door seal, and the rinsed water will pass through the sensor.

The sensor can be a temperature sensor, which detects by using the characteristic that the temperature changes when water flows through; the sensor can also be a weak current conductor, which detects whether water flows through by using the inductive coupling method. Specifically, a cover full of mesh holes can be placed just below the central axis of the clothing inlet, a super-hydrophobic coating is sprayed under the cover, and the sensor is arranged under the cover. The super-hydrophobic coating is added to allow water to flow through here quickly without accumulating water, thereby improving the accuracy of the sensor in detecting water leakage in the washing machine.

[0072] The spray component is located inside the washing machine. When the door is closed, the spray component can wash the inner surface of the door and the door seal. When the door is completely closed, the washing water will not flow to the sensor position; when the door is not completely closed, the washing water will flow from the door gap to the sensor position due to gravity and be detected by the sensor.

[0073] When the user puts clothes into the washing machine through the door and closes the door, if the clothes are not caught by the door, the door and the door seal fit perfectly, and the water in the washing machine will not leak out of the door, that is, no water will flow through the sensor. If the clothes are caught by the door, a gap will form between the door and the door seal, and the water in the washing machine will leak out of the door; or when the washing machine is running, the door is lifted up by the clothes, causing water leakage, and due to the effect of gravity, water will leak out from the location of the sensor, so that the sensor detects that there is water at the bottom of the clothing inlet.

[0074] See also Figure 2 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The control device of the washing machine may include: an acquisition unit 102 and a control unit 104.

[0075] The acquisition unit 102 is configured to acquire the detection result of the sensor and the current washing steps after the washing machine starts to execute the washing program; the washing steps are the steps included in the washing program. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0076] In some embodiments, the laundry program includes the following steps in sequence: a washing step, a washing and dehydration step, a rinsing step, a rinsing and dehydration step, and a final dehydration step.

[0077] The control unit 104 is configured to control the spray component to work according to the current washing step. The specific functions and processing of the control unit 104 refer to step S120.

[0078] In some embodiments, the control unit 104 controls the specific process of the spray component to work according to the current washing step, including: when the current washing step proceeds to the washing step, before washing, the spray component is controlled to work. Alternatively, when the current washing step proceeds to the final dehydration, the spray component is controlled to work before and after the final dehydration.

[0079] In the washing program, the spray component is combined, and the final washing steps can be: detecting the water level in the barrel, rinsing the machine door, weighing, washing, washing and dehydrating, rinsing, rinsing and dehydrating, the last rinse, rinsing the machine door, final dehydration, rinsing the machine door, shaking the clothes. Among them, when detecting the water level in the barrel, if the water level in the barrel is high, drain it, and if the water level is low, proceed to the next step. Weighing is to weigh the clothes in the barrel, so as to select the appropriate parameters such as the water intake. The number of rinses can be set according to the actual situation. Usually the machine door is made of transparent material, which is convenient for users to observe the situation in the barrel.

[0080] When the spray component is controlled to work to flush the machine door, a flushing time is preset. When the working time of the spray component reaches the flushing time, the spray component stops working and the washing machine executes the next step.

[0081] After the final spin, there may be foam left on the door and door seal. Rinsing the door at this time may wash the foam onto the clothes. Therefore, rinse the door before the final spin to minimize the foam on the clothes. Rinsing the door after the final spin is used to clean the door and door seal.

[0082] The flushing door before weighing is used to determine whether the external environment affects the sensor's detection results according to the sensor's detection results during the flushing process. Specifically, since the water level in the tub has been drained below the preset water level in the tub water level detection step, the water in the tub will not pass through the sensor position. At this time, if water in the external environment penetrates into the sensor from the door seal, it will affect the subsequent judgment of whether the washing machine is leaking, making the judgment inaccurate.

[0083] In some embodiments, the control unit 104 is further configured to: before the washing machine starts to execute the washing program, determine whether there is water at the bottom of the clothing inlet according to the detection result of the sensor; if there is water at the bottom of the clothing inlet, then during the current execution of the washing program by the washing machine, no longer detect whether the washing machine is leaking. If there is no water at the bottom of the clothing inlet, then during the current execution of the washing program by the washing machine, control the spray component to work according to the current washing step, and control the start and stop of the washing machine and the speed of the drum according to the current washing step when it is determined that the washing machine is leaking.

[0084] Before the washing machine starts the washing program and weighs, the water in the barrel has been drained and no water will pass through the sensor position. If the sensor detects water at the bottom of the door frame, it is considered that water in the external environment has penetrated into the sensor position. Therefore, it is impossible to accurately determine whether there is a water leak in the washing machine based on the sensor's detection results, and it is impossible to determine whether the door is not closed tightly. At this time, the app and the whole machine will prompt that the washing machine will no longer be detected for water leakage during this washing process, and the washing machine will run to the end according to the washing program. Conversely, if the sensor detects that there is no water at the bottom of the door frame, it means that the sensor's detection can accurately determine whether the washing machine is leaking. Therefore, when the washing machine runs according to the washing program, it is determined whether the washing machine is leaking based on the current washing steps and the sensor's detection results, and the working state of the washing machine is controlled to make the washing machine more intelligent.

[0085] The control unit 104 is further configured to determine whether the washing machine is leaking according to the detection result of the sensor. The specific functions and processing of the control unit 104 are shown in step S130. Specifically, it is determined that the door is leaking due to the door not being closed tightly.

[0086] In some embodiments, the control unit 104 determines whether the washing machine is leaking according to the detection result of the sensor, including: determining whether there is water at the bottom of the clothing inlet according to the detection result of the sensor; if it is determined that there is water at the bottom of the clothing inlet, it is determined that the washing machine is leaking; if it is determined that there is no water at the bottom of the clothing inlet, it is determined that the washing machine is not leaking.

[0087] Because it has been determined that the external environment will not affect the accuracy of the sensor in judging whether the washing machine is leaking before the washing program is started, it is believed that whether there is water at the bottom of the clothing inlet can indicate whether the washing machine is leaking.

[0088] The control unit 104 is further configured to control the working state of the washing machine and the speed of the drum according to the current washing step if it is determined that the washing machine is leaking. The specific functions and processing of the control unit 104 are shown in step S140. The working state of the washing machine includes starting and stopping the washing machine, switching different washing programs, skipping a step in the washing program, and providing message prompts.

[0089] When the sensor detects water during the operation of the washing machine, it may be that the water inside the washing machine has leaked out, or that the water outside the washing machine has penetrated from the door seal to the sensor position. Therefore, it is not accurate to judge whether the washing machine is leaking based on the sensor's detection results alone. Because this solution combines the washing step of the washing machine and the sensor's detection results to more accurately judge whether the washing machine is leaking; at the same time, the working state of the washing machine is controlled according to the degree of the leakage, avoiding the washing machine being shut down as soon as a leakage is detected, which affects the user experience, making the washing machine more intelligent.

[0090] In some embodiments, the control unit 104 controls the specific process of the working state of the washing machine and the rotation speed of the drum according to the current washing step, including: if the current washing step proceeds to the washing step and the spray component is in a working state, the washing machine is controlled to stop executing the washing program, and the washing machine is controlled to issue a prompt message that the clothes are clamped by the door.

[0091] The door is rinsed before weighing and washing to determine whether the door is completely closed and whether it is leaking. Specifically, during the door rinse process, when the sensor detects water at the bottom of the clothing inlet, it is considered that the door is leaking, which may be caused by the door clamping the clothes and causing the door to not be completely closed. At this time, the washing machine is controlled to stop washing and a prompt message is issued that the door is clamping the clothes and the door is leaking. When the sensor detects that there is no water, it is considered that the door is not clamping the clothes and there is no leakage, and the washing machine continues to execute the washing program.

[0092] In some embodiments, the control unit 104 controls the working state of the washing machine and the specific process of the rotation speed of the drum according to the current washing step, and also includes: if the current washing step proceeds to the washing step or the rinsing step, obtaining the weight of the clothes in the washing machine; judging the relationship between the weight of the clothes and a preset weight; if the weight of the clothes is greater than the preset weight, controlling the washing machine to execute a preset unwinding program; or controlling the washing machine to skip the current washing step and continue to execute the washing program; if the weight of the clothes is less than or equal to the preset weight, controlling the washing machine to continue to execute the washing program and reduce the rotation speed of the drum.

[0093] The weight of the clothes in the washing machine is determined by weighing. The preset untangling program is used to solve the problem of clothes tangling. During the washing and rinsing process, there is a lot of water in the barrel and the barrel is always rotating, so the clothes may be twisted and leak. Specifically, when the weight of the clothes is greater than the preset weight, it is considered that the washing machine is under medium or high load. In this case, it is more likely that the clothes are twisted and the top door is twisted. Therefore, it is determined that the clothes are twisted and the top door is twisted. At this time, the untangling program is executed, or the current step is skipped to wash and drain or rinse and dehydrate, thereby alleviating the situation of the clothes top door. It should be noted that when the clothes top door leaks, a stall signal that the motor cannot rotate often appears at the same time. At this time, skipping the current step and entering the next step can reduce the number of fault reports and enable the washing program to be fully executed. When the weight of the clothes is less than the preset weight, it is considered that there are fewer clothes in the barrel and the clothes top door will not appear. Therefore, it is considered that the external environment has changed suddenly, or the whole machine has structural damage. At this time, the rhythm of washing is slowed down, and the rotation speed of the drum is reduced to prevent excessive foam from leaking from the washing machine to the room.

[0094] In some embodiments, the control unit 104 controls the working state of the washing machine and the speed of the drum according to the current washing step, and further includes: controlling the washing machine to continue executing the washing program if the current washing step proceeds to the washing and dehydration step or the rinsing and dehydration step.

[0095] During washing and dehydration and rinsing and dehydration, if the sensor detects water leakage, it is considered that the clothes are entangled in the top door. During the washing and dehydration and rinsing and dehydration process, the speed of the drum is low, usually not exceeding 400 revolutions. At low speeds, the entangled clothes will stick to the inner wall of the drum, and the clothes will not hit the top door, and there will be no displacement from hitting the drum. After dehydration, the position of the clothes will be disrupted, and the phenomenon of clothes entangled in the top door will be reduced. Therefore, when the sensor detects water leakage during the washing and dehydration and rinsing and dehydration steps, the washing machine executes the washing program normally.

[0096] In some embodiments, the control unit 104 controls the working state of the washing machine and the rotation speed of the drum according to the current washing step, and further includes: if the step in which the washing machine is located reaches the final dehydration step, the washing machine is controlled to continue to execute the washing program; and in the final dehydration step, the drum is controlled to run at a first rotation speed for a first time, and then the drum is controlled to run at a second rotation speed for a second time; the first rotation speed < the second rotation speed.

[0097] During the final spin, if the sensor detects a leak, it is considered that the clothes are entangled with the top door. Usually the rotation speed of the drum is relatively high during the final spin. Therefore, in order to solve the problem of clothes entangled with the top door, a low-speed pre-spin is added during the final spin, and the maximum rotation speed of the final spin is reduced. That is, the final spin is divided into two stages. The first stage is a low-speed pre-spin, and the rotation speed of the low-speed pre-spin is a lower first rotation speed. The second stage is the final spin, and the final spin is a higher second rotation speed, and the second rotation speed is less than the preset maximum rotation speed during the final spin. By adding a low-speed pre-spin stage and reducing the maximum rotation speed of the spin, the clothes are kept close to the inner wall of the drum at a low speed, which alleviates the problem of clothes hitting the top door.

[0098] If the sensor detects a water leak during the final spin speed reduction stage, or during the door rinsing stage after the final spin, it is considered that the sensor detected the water leak due to a change in the external environment or structural damage to the washing machine. Since the washing program is about to end at this time and no water is entering the barrel, no action is taken.

[0099] Figure 4 The flowchart of another embodiment of the control method of the washing machine of the present invention comprises:

[0100] Step 1: After the washing machine door is closed, the washing program is started, and the sensor detects whether water is continuously flowing through. If water is detected to be continuously flowing through, the whole machine and the app will prompt, and the washing machine will continue to run the washing program. If no water is detected to be flowing through, the clothes will be weighed and step 2 will be executed.

[0101] Step 2: The spray pipe rinses the glass bowl and door seal of the machine door. During this process, the sensor detects whether water is continuously flowing through. If water is detected to be continuously flowing through, the washing process is suspended and an alarm is issued to the user, indicating that clothing may be caught in the machine door. If no water is detected to be flowing through, the washing process continues and step 3 is performed.

[0102] Step 3, the sensor continues to detect whether water is passing through. If the sensor continues to detect water passing through, if it is in the washing or rinsing stage, then execute step 4; if it is in the washing and dehydration or rinsing and dehydration stage, then control the washing machine to continue the washing program and re-execute step 3; if it is in the final dehydration or shaking stage, then execute step 5; if it is in the dehydration speed reduction stage of the final dehydration, it is considered that the whole machine is structurally damaged or the external environment has changed, and the washing machine is controlled to continue the washing program until it ends. If no water is detected passing through, then control the washing machine to continue the washing program until it ends.

[0103] Step 4, determine whether the load weight level in the washing machine is medium or multi-load. If the load weight level is medium or multi-load, it is determined that the clothes are entangled and twisted, and the top door is leaking. At this time, the untwisting process is run, and then the water is drained to the door opening water level, and the next washing stage is continued, and step 3 is re-executed. If the load weight level is light load, it is considered to be a false detection or structural damage of the whole machine or a change in the external environment. At this time, the washing rotation rhythm is reduced and the machine is operated to the next stage, or a fault is reported due to structural damage, and step 3 is re-executed.

[0104] Step 5: It is determined that the clothes are stuck between the door seals, or the clothes are seriously entangled and hit the door. Add a low-speed pre-spin during the final spin cycle and lower the maximum speed setting. If it is the shaking stage, no processing is done and the washing process continues until the end.
