[0002] In modern society, when the existing washing equipment is draining, if the water level sensor of the washing equipment is abnormal or fails, the machine cannot drain normally. The water level sensor plays an important role in monitoring the water level in the washing equipment so as to control the water inlet and drainage process of the washing equipment. However, due to the particularity of the water level sensor, once a failure occurs, it needs to be repaired or replaced. Manual replacement of the water level sensor of the washing equipment requires professional skills and time, which brings inconvenience to users. Since the replacement of the water level sensor is more troublesome, it also increases the troubles of users encountering drainage failures when using the washing equipment. Moreover, when the water level sensor of the washing equipment is abnormal or fails, the user may not be able to discover the problem in time and take corresponding repair measures; this may cause the drainage problem in the washing process to not be solved in time, resulting in the clothes not being thoroughly washed or even causing Machine damage; in addition, the existing drainage control method of washing equipment may not provide sufficient ability to detect and troubleshoot the cause of the fault. When the washing equipment sends out a drainage fault alarm signal, the user may not be able to accurately determine whether the drainage problem is caused by a water level sensor failure or other faults. This may require the user to spend extra time and energy to find the cause of the fault and take appropriate repair measures. The existing drainage control method of washing equipment lacks flexibility and intelligence. The user may not be able to adjust the drainage mode and parameters of the washing equipment according to personal needs and specific circumstances; for example, when the user only washes a small amount of clothes or hopes to save water resources, the existing drainage control method may not meet the needs. The user may hope to be able to remotely monitor and adjust the drainage of the washing equipment through a smartphone or other device so as to flexibly control and optimize it according to actual conditions.

[0003] In general, the existing drainage control method for washing equipment has defects such as troublesome replacement of water level sensors, inconvenient troubleshooting, and lack of flexibility and intelligence. Therefore, it is necessary to improve the existing technology and provide a more convenient, flexible and intelligent drainage control method for washing equipment to improve the user experience and the performance of the washing equipment.

[0017] Determine the actual drainage volume L of the washing equipment 排实际 Is it within the allowable range, i.e. L 排最小值 ≤L 排实际 ≤L排最大值 ;

[0018] If L 排最小值 ≤L 排实际 ≤L 排最大值 If the condition is established, the reason why the washing device issues an alarm is due to a drainage failure caused by a blockage in the drainage pipe;

[0019] If L 排最小值 ≤L 排实际 ≤L 排最大值 If it is not true, then the reason why the washing device issues an alarm is not due to a drainage failure caused by a blockage in the drain pipe, and the user is prompted to continue to investigate the cause of the fault alarm.

[0020] Furthermore, the water inlet information of the washing equipment includes the water inlet volume L 进 , water flow rate is A 进流 , water inlet time is T1,

The present application reduces the time of manual replacement of the water level sensor of the washing device, brings convenience to users, and reduces the troubles of users encountering drainage failures when using the washing device. Moreover, when the water level sensor of the washing device is abnormal or fails, users can find the problem in time and take corresponding repair measures; timely solve the drainage problem in the washing process, so that the clothes are thoroughly washed or the machine is protected from damage; in addition, since the existing drainage control method of the washing device may not have Provide sufficient ability to detect and troubleshoot the cause of the fault.

[0040] Example 1

[0041] A method for controlling drainage of a washing device, wherein before drainage, the washing device includes but is not limited to a washing machine, and a mobile terminal obtains water inflow information of the washing device, wherein the water inflow information includes a water inflow flow rate A 进流, water inlet time T1, the mobile terminal according to the water inlet flow A of the washing device 进流 , water inlet time T1, calculate the water inlet volume L of the washing equipment 进 , that is, the water inlet of the washing equipment is L 进 =A 进流 ×T1, therefore, the water inlet information includes the water inlet flow rate A 进流 , water inlet time T1, and water inlet volume L of the washing device 进 The mobile terminal transmits the water inlet information to the control panel of the washing device, and the control panel obtains the drainage time range (T0, T2) allowed by the washing device. The method for obtaining the drainage time range (T0, T2) allowed by the washing device is: the drainage flow rate A of the washing device 排流 Remain unchanged, according to L 进 =A 进流 ×T1 to obtain the allowable drainage time of the washing device. Modern washing machines often have a fuzzy water level function. The fuzzy water level refers to a function in the washing machine that automatically adjusts the water level according to the load and type of clothes. Traditional washing machines usually have fixed water level options, but different sizes and types of clothes require different amounts of water. The fuzzy water level function can determine the load of clothes through sensors or intelligent algorithms, thereby automatically adjusting the water level to an appropriate amount of water. This can avoid wasting water resources with excessive water, ensure the washing effect, and reduce damage to clothes. According to the fuzzy water level function combined with the moisture content of the laundry, the allowable drainage time range (T0, T2) of the washing device is obtained, and the actual drainage volume T of the washing device is determined. 排实际 Is it satisfied that T0<T 排实际 Within the time range of <T2, the mobile terminal will record the actual drainage time T of the washing device. 排实际 Compared with the drainage time range (T0, T2) allowed by the washing equipment, the actual drainage time T of the washing equipment is determined. 排实际 Is it within the drainage time range (T0, T2) allowed by the washing equipment? If so, the actual drainage time T 排实际 Satisfy T0<T 排实际 <T2, the washing equipment is draining normally, if not, the actual drainage time is T 排实际 Does not satisfy T0<T 排实际 <T2, an alarm is issued.

[0042] In this embodiment, by comparing the actual drainage time with the allowed drainage time, it is determined whether the drainage of the washing equipment is within a reasonable range, thereby reducing the time for manual replacement of the water level sensor, making it faster and more accurate to troubleshoot the cause of the fault. The present application determines that if the actual drainage time exceeds the set allowable range, it may mean that there are problems such as blockage or obstruction in the drainage pipe, or that there is a fault in the equipment itself. In this way, drainage problems can be discovered earlier, and measures can be taken in time to repair and solve them. By determining whether the drainage time is normal, the normal operation of the washing equipment and the safety of users can be ensured, and unexpected situations that may be caused by abnormal drainage due to equipment failure can be avoided, thereby reducing the risks for users when using the washing equipment.

[0043] In this embodiment, the washing device is connected to the network and a mobile terminal is used to calculate the water flow rate A of the washing device. 进流 , water inlet time T1, calculate the water inlet volume L of the washing equipment 进 , and transmit the water inlet information to the control panel of the washing equipment. If the washing equipment is set according to the water inlet flow rate A of the washing equipment 进流 , water inlet time T1, calculate the water inlet volume L of the washing equipment 进 , increasing the cost of the washing equipment, the use of the terminal can achieve a popularization effect, and is convenient and fast, and will not increase the design and manufacturing costs of other washing equipment.

[0044] In this embodiment, the method is applicable to both upper drainage type washing equipment and lower drainage type washing equipment.

[0045] In this embodiment, flow sensors are installed at the water inlet and the outlet of the washing device, respectively, wherein the flow sensor installed at the water inlet is used to measure the water inlet flow rate A of the washing device. 进流 ; The present application sets a flow sensor at the water inlet to replace the water level sensor, and transmits the water inlet information and the drainage information to the control panel of the washing device according to the flow sensor. When the water level sensor of the washing device is abnormal or fails, the washing device cannot drain normally. The water level sensor plays an important role in monitoring the water level in the washing device so as to control the water inlet and drainage process of the washing device. Due to the particularity of the water level sensor, once a failure occurs, it needs to be repaired or replaced. The present application reduces the time for manual replacement of the water level sensor of the washing device, brings convenience to users, and reduces the troubles of users encountering drainage failures when using the washing device. Moreover, when the water level sensor of the washing device is abnormal or fails, the user can find the problem in time and take corresponding repair measures; solve the drainage problem in the washing process in time, so that the clothes are thoroughly washed or the machine is protected from damage; wherein, the flow sensor installed at the drainage port is used to measure the actual drainage volume L within a period of time 排实际When an alarm is issued, the cause of the fault is assisted to be eliminated. After the fault alarm is issued, a flow sensor is set through the drain port to measure the actual drainage volume L of the washing equipment. 排实际 ,

[0046] The water output within the time period is different because the washing machine brand and model are different, so the drainage time is also different, but the drainage time of the existing washing machine is between 1-3 minutes; for example: when the washing machine issues a fault alarm, the flow sensor at the water outlet measures the drainage volume of the washing machine 1-3 minutes after the fault alarm occurs as the actual drainage volume L 排实际 , according to the actual water output L 排实际 Determine whether the cause of the fault alarm is a drainage failure caused by a blockage in the drain pipe.

[0047] The allowed drainage volume L of the washing equipment is obtained according to the water inlet information of the washing equipment. 出 The range of L 排最小值 and L 排最大值 ,

[0048] Determine the actual discharge volume L of the washing equipment according to the water inlet information of the washing equipment 排实际 Is it within the allowable range, i.e. L 排最小值 ≤L 排实际 ≤L 排最大值 ,

[0049] If L 排最小值 ≤L 排实际 ≤L 排最大值 If the fault alarm of the washing device is established, the reason is that the drainage failure caused by the blockage of the drainage pipe.

[0050] If L 排最小值 ≤L 排实际 ≤L 排最大值 If it is not true, then the reason why the washing device issues a fault alarm is not due to a drainage failure caused by a blockage in the drain pipe, and the user is prompted to continue to investigate the cause of the fault alarm.

[0051] In this embodiment, by measuring the actual drainage volume, it can be determined whether the cause of the fault alarm is due to the blockage of the drain pipe. If the actual drainage volume is within the allowable range, the possibility of the blockage of the drain pipe can be ruled out, helping the user to quickly locate the cause of the fault and avoid unnecessary maintenance or troubleshooting. The flow sensor can quickly and accurately measure the actual drainage volume and compare it with the set allowable range to determine the cause of the fault. Through this automated method, the speed and accuracy of fault diagnosis can be improved, the time users wait for maintenance can be reduced, and the overall service quality can be improved; if the actual drainage volume is not within the allowable range, that is, the blockage of the drain pipe is not the cause of the fault, the system will prompt the user to continue to troubleshoot the cause of the fault alarm, which helps to guide the user to continue to check other possible fault points according to the actual situation, avoid blind operation or misunderstanding of the cause of the fault, and improve the user's self-repair ability; by using the flow sensor to assist in troubleshooting the cause of the fault, the drainage fault can be quickly solved, reducing the user's troubles and distress, which can improve the user's satisfaction with the washing equipment and provide the user with a more convenient user experience.

[0052] In this embodiment, the control panel of the washing device and the user's mobile phone can be connected via wireless communication, and the user's mobile phone can receive the current drainage status and alarm information of the washing device sent by the control terminal.

[0053] The user can reselect / adjust the drainage state of the washing device according to the alarm information on the mobile phone, and send a control signal to the washing device. Through the wireless communication connection between the mobile phone and the washing device, the control panel of the washing device receives the signal of the reselected / adjusted drainage state of the washing device and executes it.

[0054] Users can remotely control the washing equipment. No matter where they are, as long as their mobile phones are connected to the Internet, they can monitor the status of the washing equipment in real time and perform operational control. There is no need for users to go to the equipment in person to operate, which provides great convenience and flexibility. By receiving the drainage status and alarm information of the washing equipment on the mobile phone, users can promptly understand the working status and problems of the equipment, which enables users to quickly detect abnormalities of the equipment during the washing process and take timely measures to adjust or repair it to avoid further expansion of the fault. By reselecting / adjusting the drainage status of the washing equipment on the mobile phone and sending control signals to the equipment, users can more actively participate in the control of the washing process and can flexibly adjust it according to actual needs and washing conditions, providing a more personalized and convenient user experience. By receiving the alarm information of the washing equipment on the mobile phone, users can convey this information to the after-sales service or maintenance team for online support or remote diagnosis, which helps to improve the diagnostic efficiency and repair speed of equipment failures, reduce users' waiting time for repairs, and improve the quality of after-sales service.
