Description

Technical Field

[0001] The present invention relates to the field of washing machine technology, and in particular to a washing machine drainage control method, device, washing machine and storage medium. Background Technology

[0002] With the improvement of people's living standards, washing machines have entered thousands of households and become one of the most commonly used home appliances. Washing machines can wash various clothing materials, but the washing process causes wear and tear on the clothes. The lint and dander from this wear and tear are discharged through the drain pipe. As lint and dander accumulate, they can clog the drain pipe, causing the washing machine to stop operating. If users don't notice this in time, clothes will remain soaked in the washing machine for a long time, breeding bacteria and developing a foul odor. Modern washing machines have a filter at the drain outlet to isolate lint and dander, but users need to clean it regularly. If users don't clean it in time, it can easily lead to poor drainage or blockage, greatly increasing drainage time and reducing washing efficiency. Summary of the Invention

[0003] This invention provides a washing machine drainage control method, device, washing machine, and storage medium, aiming to solve the problem of low washing efficiency caused by poor drainage or blockage in existing washing machines.

[0004] In a first aspect, embodiments of the present invention provide a washing machine drainage control method. The washing machine includes an inner drum, an outer drum sleeved outside the inner drum, and a drainage pipe and a pressurizing assembly connected to the outer drum. A detection motor and a fan blade mounted on the detection motor are provided in the drainage pipe. The fan blade is used to drive the detection motor to rotate when the washing machine drains water. The method includes:

[0005] The reference power is calculated based on the first voltage of the detected motor.

[0006] The comparison power is calculated based on the second voltage of the detection motor, and the drainage pipe is used to detect whether there is an abnormality in drainage based on the comparison power and the reference power.

[0007] If the drainage pipe malfunctions, the pressurization component is activated to restore normal drainage.

[0008] Secondly, embodiments of the present invention also provide a washing machine drainage control device. The washing machine includes an inner drum, an outer drum sleeved outside the inner drum, and a drainage pipe and a pressurizing assembly connected to the outer drum. A detection motor and a fan blade mounted on the detection motor are provided in the drainage pipe. The fan blade is used to drive the detection motor to rotate when the washing machine drains water. The fan blade includes:

[0009] A calculation unit is used to calculate a reference power based on the first voltage of the detected motor.

[0010] The detection unit is used to calculate the comparison power based on the second voltage of the detection motor, and to detect whether the drainage pipe is abnormal based on the comparison power and the reference power.

[0011] The control unit is used to control the pressurization component to open if the drainage pipe is abnormal, so as to restore the drainage pipe to normal drainage.

[0012] Thirdly, embodiments of the present invention also provide a washing machine, which includes:

[0013] Inner cylinder;

[0014] The outer cylinder is fitted over the outer part of the inner cylinder;

[0015] A drainage pipe, which is fixedly installed at the bottom of the outer cylinder;

[0016] A pressurization assembly includes an air pump and a water pump, wherein the air pump is connected to the outer cylinder via an air duct, and the water pump is connected to the drainage duct via a water pumping duct.

[0017] A detection component is installed inside the drain pipe. The component includes a detection motor and a fan blade mounted on the detection motor. The fan blade is used to drive the detection motor to rotate when the washing machine drains water.

[0018] Fourthly, embodiments of the present invention also provide a washing machine, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0019] Fifthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0020] This invention provides a washing machine drainage control method, device, washing machine, and storage medium. The washing machine includes an inner drum, an outer drum sleeved outside the inner drum, and a drainage pipe and a pressurizing assembly connected to the outer drum. A detection motor and fan blades mounted on the detection motor are installed in the drainage pipe. The fan blades drive the detection motor to rotate during drainage. The method includes: calculating a reference power based on a first voltage of the detection motor; calculating a comparison power based on a second voltage of the detection motor; and detecting whether the drainage pipe is experiencing drainage abnormalities based on the comparison power and the reference power. If the drainage pipe is experiencing drainage abnormalities, the pressurizing assembly is opened to restore normal drainage.

[0037] Please see Figure 1 , Figure 1 This is a schematic diagram of a washing machine provided in an embodiment of the present invention. Figure 1As shown, the washing machine 10 includes an inner drum 11, an outer drum 12, a drain pipe 13, a pressurizing assembly, and a detection assembly 16. The outer drum 12 is fitted over the inner drum 11; the drain pipe 13 is fixedly installed at the bottom of the outer drum 12; the pressurizing assembly includes an air pump 14 and a water pump 15, the air pump 14 being connected to the outer drum 12 via an air pipe, and the water pump 15 being connected to the drain pipe 13 via a water pumping pipe; the detection assembly 16 is installed inside the drain pipe 13 and includes a detection motor 162 and a fan blade 161 mounted on the detection motor 162, the fan blade 161 driving the detection motor 162 to rotate when the washing machine 10 drains water. It should be noted that, in this embodiment, the washing machine 10 also includes a water tank 17, which is connected to the water pump 15 via a water pumping pipe and is used to store water pumped from the inner drum 11. The bottom of the water tank 17 is also provided with a water tank 17 drain outlet. Opening the water tank 17 drain outlet can drain the water in the water tank 17 into the drain pipe 13. Understandably, the air pump 14 is used to draw outside air into the inner cylinder 11 so that the pressure in the inner cylinder 11 is greater than the pressure at the drain pipe 13. By utilizing the pressure difference, the water in the inner cylinder 11 is discharged, thereby flushing away the lint and lint accumulated on the filter screen in the drain pipe 13, ensuring normal drainage of the drain pipe 13. The water pump 15 is used to draw water from the inner cylinder 11 into the water tank 17. Then, by turning off the water pump 15 and turning on the air pump 14, outside air is drawn into the inner cylinder 11, thereby increasing the pressure in the inner cylinder 11 again. Then, the water in the inner cylinder 11 is discharged again by utilizing the pressure difference, thereby flushing away the lint and lint accumulated on the filter screen in the drain pipe 13, ensuring normal drainage of the drain pipe 13. It should also be noted that in this embodiment, the detection motor 162 and the fan blade 161 installed on the detection motor 162 are used to detect whether the drainage pipe 13 is abnormal. When the drainage pipe 13 is abnormal, the opening and closing of the pressurization component connected to the outer drum 12 is controlled to restore the drainage pipe 13 to normal drainage. This not only eliminates the need for users to clean the filter screen regularly, but also allows for timely detection of drainage problems or blockages, reducing drainage time and improving washing efficiency.

[0038] Figure 2 This is a schematic flowchart of the washing machine drainage control method provided in an embodiment of the present invention. Figure 2 As shown, the method includes the following steps S100-S120.

[0039] S100. Calculate the reference power based on the first voltage of the detected motor.

[0040] In this embodiment of the invention, when the washing machine finishes its first wash and enters the first drainage stage, the control center of the washing machine acquires the first voltage of the detection motor as a reference voltage U0. That is, the first voltage is the voltage of the detection motor obtained during the first drainage stage of the washing machine's first wash. Based on the reference voltage U0, the resistor R0 corresponding to the detection motor, and a preset resistor R1, the power of the detection motor is calculated as a reference power P0. Specifically, as follows... Figure 3a As shown, the system includes the detection motor and voltage sampling circuit. The sampling circuit includes resistors R0 and R1, and capacitor C. Specifically, resistors R0 and R1 are connected in series, one end of resistor R2 is connected to one end of resistor R1, the other end of resistor R2 is connected to the control center, the other end of resistor R1 is grounded, and capacitor C is connected in parallel with resistor R2. The control center obtains the voltage U across resistor R1. R1 =U0*R1 / (R0+R1), P0=U0*U R1 / (R1). In Figure 3b The diagram shows the fan blades mounted on the detection motor. It should be noted that in this embodiment, the control center is an MCU. Understandably, the power of the motor rotation during the first use of the washing machine for the first drainage is used as the reference power because there are no issues with drainage obstruction or blockage during the first drainage. It should also be noted that in this embodiment, when obtaining the voltage of the detection motor, the rotational speed of the fan blades can also be obtained. Since the fan blades are coaxial with the motor, the rotational speed of the fan blades is the rotational speed of the detection motor. That is, the mechanical energy of the fan blade rotation is converted into the electrical energy of the motor. By detecting the electrical energy of the motor, such as its power, the normality of drainage through the drainage pipe can be characterized. Understandably, the normality of drainage through the drainage pipe can also be characterized by the rotational speed of the detection motor.

[0041] S110. Calculate the comparison power based on the second voltage of the detection motor, and detect whether the drainage pipe is abnormal based on the comparison power and the reference power.

[0042] In an embodiment of the present invention, when the washing machine is not used for the first time or is not in the first drainage during the first use, that is, when the washing machine is not draining water for the first time during washing, the second voltage of the detection motor is obtained in real time as the comparison voltage U1. Understandably, the second voltage is the voltage of the detection motor obtained when draining water during non-first use of the washing machine or the voltage of the detection motor obtained during non-first drainage during the first use of the washing machine. According to the comparison voltage U1, the resistance R0 corresponding to the detection motor, and the preset resistance R1, the power of the detection motor is calculated as the reference power P1. Understandably, the voltage obtained by the control center on the resistance R1 is U R1 = U1 * R1 / (R0 + R1), P1 = U1 * U R1 / (R1). After calculating the comparison power U1, it is detected whether the drainage pipe is draining abnormally according to the comparison power P1 and the reference power P0. Specifically, the comparison power is compared with half of the reference power; if the comparison power is less than half of the reference power, that is, if P1 < P0 / 2, it is determined that the drainage pipe is draining abnormally; if the comparison power is not less than half of the reference power, P1 ≥ P0 / 2, it is determined that the drainage pipe is draining normally. Understandably, the closer the comparison power P1 is to the reference power P0, the more normal the drainage of the drainage pipe is and there is no blockage. On the contrary, it indicates that the drainage pipe is draining abnormally. It should be noted that in this embodiment, if the drainage pipe is draining normally, it can be directly drained until the end.

[0043] S120. If the drainage pipe is draining abnormally, control the booster component to open so that the drainage pipe resumes normal drainage.

[0044] In an embodiment of the present invention, if the drainage pipe is draining abnormally, that is, if P1 < P0 / 2, control the booster component to open so that the drainage pipe resumes normal drainage. Among them, the booster component includes an air pump, a water pump, and a water tank connected to the water pump. The air pump is connected to the outer cylinder, and the water pump is connected to the outer cylinder through the drainage pipe. It should be noted that in this embodiment, by borrowing the air pump and the water pump, the pressure in the inner cylinder can be increased, so that the pressure in the inner cylinder is greater than the pressure in the drainage pipe, and then a pressure difference is formed to drain the water in the inner cylinder, thereby flushing away the accumulated lint and thread flocs on the filter screen in the drainage pipe and making the drainage pipe drain normally. Understandably, after the drainage pipe drains normally, it is directly drained until the end. It should also be noted that in this embodiment, controlling the booster component to open is to first control the air pump to open so that the drainage pipe resumes normal drainage.

[0045] In some embodiments, such as this embodiment, as Figure 4 As shown, step S120 may include steps S121-S125.

[0046] S121. Turn on the air pump;

[0047] S122. Calculate the comparison power based on the obtained voltage of the detected motor;

[0048] S123. If the comparison power is not less than half of the reference power and the washing machine's drainage volume is normal, then the air pump is turned off, and it is determined that the drainage pipe has returned to normal.

[0049] S124. If the comparison power is less than half of the reference power or the washing machine's drainage volume is abnormal, then the air pump is turned off and the water pump is turned on to draw a preset amount of water into the water tank.

[0050] S125. Turn off the water pump, turn on the air pump, and return to step S122 until the drainage pipe returns to normal.

[0051] In an embodiment of the present invention, if the drainage of the drainage pipe is abnormal, that is, if P1 < P0 / 2, the air pump is turned on to extract external air into the inner cylinder, increasing the pressure in the inner cylinder. At this time, the comparison power P2 is calculated according to the obtained voltage of the detection motor, and it is determined whether the comparison power is less than half of the reference power; if the comparison power is not less than half of the reference power, that is, if P2 ≥ P0 / 2, it indicates that the drainage volume in the drainage pipe has increased compared with that before the air pump is turned on, which also means that the pressure in the inner cylinder is greater than the pressure in the drainage pipe, forming an air pressure difference; it is further determined whether the drainage volume of the washing machine is normal. If the drainage volume of the washing machine is normal, it indicates that the air pressure difference is sufficient to drain the water in the inner cylinder, thereby flushing away the lint and thread flocs accumulated on the filter screen in the drainage pipe, making the drainage of the drainage pipe normal. It should be noted that in this embodiment, the step of determining whether the drainage volume of the washing machine is normal is specifically as follows: obtain the drainage flow rate of the washing machine. If the drainage flow rate of the washing machine is greater than the preset drainage flow rate threshold, it is determined that the drainage volume of the washing machine is normal; otherwise, if the drainage flow rate of the washing machine is not greater than the preset drainage flow rate threshold, it is determined that the drainage volume of the washing machine is abnormal; calculating the comparison power P2 according to the obtained voltage U2 of the detection motor is similar to calculating the comparison power P1, which will not be elaborated here. It should also be noted that in an embodiment of the present invention, the liquid level sensor built in the washing machine is used to collect the liquid level values before and after the air pump is turned on, and the difference between the front and rear liquid level values is calculated to obtain the drainage volume; the preset drainage flow rate threshold is set according to actual needs and will not be specifically limited here.

[0052] Further, if the comparison power is less than half of the reference power, that is, if P2 < P0 / 2, it indicates that the drainage volume in the drainage pipe has not increased compared with that before the air pump is turned on, which also means that the pressure difference between the pressure in the inner cylinder and the pressure in the drainage pipe is small, and the formed air pressure difference is insufficient. To increase the air pressure difference, the air pump is turned off, and the water pump is turned on to extract a preset amount of water into the water tank, where the preset amount of water can be set according to actual needs and will not be limited here; after extracting the preset amount of water, the water pump is turned off, the air pump is turned on, and the process returns to execute calculating the comparison power P3 according to the obtained voltage U3 of the detection motor, and continue to compare the size of the reference power P0 and half of the comparison power. If P3 ≥ P0 / 2, continue to detect whether the drainage volume of the washing machine is normal, and repeat the cycle until it meets that the comparison power is not less than half of the reference power and the drainage volume of the washing machine is normal, then turn off the air pump and determine that the drainage pipe has returned to normal.

[0053] Further, if the comparison power is not less than half of the reference power, that is, P2≥P0 / 2, it indicates that the drainage volume in the drainage pipe has increased compared with that before the air pump is turned on, which also means that the pressure in the inner cylinder is greater than the pressure in the drainage pipe, forming the air pressure difference. Then, it is judged whether the drainage volume of the washing machine is normal. If the drainage is normal, it indicates that the formed air pressure difference is large, and the lint and thread flocs accumulated on the filter screen in the drainage pipe can be washed away without turning on the water pump, making the drainage pipe drain normally.

[0054] For easy understanding, Figure 5 is the flow diagram of the washing machine drainage control method provided by the embodiment of the present invention. As Figure 5 shown, first judge whether P1 is less than P0 / 2. If P1≥P0 / 2, it indicates that the drainage pipe is normal and the drainage ends; if P1<P0 / 2, it indicates that the drainage pipe is abnormal, then turn on the air pump to extract external air into the inner cylinder to increase the pressure in the inner cylinder; calculate the comparison power P2 through the obtained voltage U2 of the detection motor, and judge whether Pi is less than P0 / 2. At this time, i = 2. If P2<P0 / 2, it indicates that the drainage pipe has not recovered to normal and the air pressure difference formed between the inner cylinder and the drainage pipe is insufficient. Then turn off the air pump and turn on the water pump to pump a preset amount of water into the water tank, and then turn on the air pump to extract external air into the inner cylinder, thereby increasing the pressure in the inner cylinder, that is, increasing the air pressure difference. After increasing the air pressure difference, calculate the comparison power P3 through the obtained voltage U3 of the detection motor, and judge whether Pi is less than P0 / 2. At this time, i = 3, until Pi≥P0 / 2; when Pi≥P0 / 2, i = 2, 3, 4......, judge whether the drainage volume of the washing machine is normal. If the drainage volume is normal, the drainage ends. If the drainage volume of the washing machine is not normal, return to execute the step of turning off the air pump and turning on the water pump until Pi≥P0 / 2 and the drainage volume is normal, indicating that the drainage pipe has recovered to normal and the drainage ends.

[0055] It should be noted that in the embodiment of the present invention, the detection motor and the fan installed on the detection motor are used to detect whether the drainage pipe drains abnormally. When the drainage pipe drains abnormally, the opening and closing of the air pump and the water pump connected to the outer cylinder are controlled to make the drainage pipe drain normally. Not only does it not require the user to clean the filter screen regularly, but it can also timely detect poor drainage or blockage, reduce the drainage time, and improve the laundry efficiency.
