It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0048] Figure 1 Flowchart of a drainage method of a laundry treatment device according to an embodiment of the present invention. This embodiment is applicable to the situation where the laundry treatment device processes laundry. This method can be executed by a laundry treatment device, which can be implemented in the form of hardware and / or software, and the laundry treatment device can be configured in an electronic device. Exemplarily, the electronic device can be a laundry treatment device such as a washing machine. As Figure 1 shown, the method includes the following steps 101 to 104.

[0049] Step 101: Obtain the current drainage duration.

[0050] The laundry treatment device in this embodiment can be a device capable of treating laundry and requiring drainage during the laundry treatment process. Exemplarily, the laundry treatment device in this embodiment can be a washing machine. Drainage in this embodiment refers to the process of discharging the water in the laundry treatment drum.

[0051] The current drainage duration refers to the duration from the start of drainage to the current moment. In step 101, the current drainage duration can be obtained through a timing device or a clock module. The current moment in this embodiment is the moment when step 101 is executed.

[0052] Step 102: If the current drainage duration is less than a preset first drainage duration threshold, determine the current remaining drainage volume in the laundry treatment drum.

[0053] In this embodiment, in order to avoid the problem of too long drainage duration caused by a failure in the drainage system of the laundry treatment device, in step 102, subsequent operations are only executed when the current drainage duration is less than the preset first drainage duration threshold. The first drainage duration threshold in this embodiment is a value determined in advance according to empirical data. The first drainage duration threshold is used to represent the longest drainage duration required by the laundry treatment device when the drainage system is not faulty. Optionally, the first drainage duration threshold in this embodiment can be any value between 8 minutes and 30 minutes. Exemplarily, the first drainage duration threshold can be 8 minutes, 10 minutes, 15 minutes, 20 minutes, or 30 minutes, etc. If the current drainage duration is greater than or equal to the first drainage duration threshold, it indicates that there is a blockage or other failure in the drainage system of the laundry treatment device, resulting in poor drainage. At this time, stop the drainage and send a drainage abnormality message to the user.

[0054] Optionally, the drainage system in this embodiment can include: a drainage pump, a drainage pipe, a drainage valve, and a drainage port. A failure in the drainage system can be a failure of any one of the drainage pump, the drainage pipe, the drainage valve, and the drainage port.

[0055] In one implementation manner, the current remaining drainage volume in the laundry treatment drum is determined according to the following method: obtain the current remaining water depth in the laundry treatment drum; determine the current remaining drainage volume according to the cross-sectional area of the laundry treatment drum, the current remaining water depth, and the density of water.

[0056] More specifically, the current remaining drainage volume is the product of the cross-sectional area of the laundry treatment drum, the current remaining water depth, and the density of water. The cross-section of the laundry treatment drum in this embodiment refers to the plane parallel to the water surface in the laundry treatment drum. According to the type of the laundry treatment device, the shape of the cross-section of the laundry treatment drum is different. For example, when the laundry treatment device is a pulsator washing machine, the cross-section of the laundry treatment drum is circular. When the laundry treatment device is a drum washing machine, the cross-section of the laundry treatment drum is rectangular.

[0057] Optionally, the current remaining water depth can be determined by a water level switch or a water level sensor.

[0058] In another implementation, the current remaining drainage volume can be determined according to the difference between the water volume injected into the laundry treatment cylinder and the water volume discharged from the laundry treatment cylinder.

[0059] Optionally, the water volume injected into the laundry treatment cylinder can be measured by a flow meter at the water inlet valve, and the water volume discharged from the laundry treatment cylinder can be measured by a flow meter at the drainage port.

[0060] Step 103: Determine the current rotation speed of the laundry treatment cylinder corresponding to the current remaining drainage volume according to the current remaining drainage volume and the mapping relationship between the preset remaining drainage volume and the rotation speed of the laundry treatment cylinder.

[0061] In this embodiment, a mapping relationship between the remaining drainage volume and the rotation speed of the laundry treatment cylinder is preset. In step 102, after determining the current remaining drainage volume in the laundry treatment cylinder, the current rotation speed of the laundry treatment cylinder corresponding to the current remaining drainage volume can be determined according to this mapping relationship.

[0062] In order to improve the safety performance during drainage and avoid phenomena such as water splashing caused by too fast rotation speed, in the mapping relationship between the preset remaining drainage volume and the rotation speed of the laundry treatment cylinder in this embodiment, the remaining drainage volume and the rotation speed are in an inverse proportion relationship. In other words, when the remaining drainage volume is larger, the corresponding rotation speed of the laundry treatment cylinder is smaller.

[0063] Furthermore, for the convenience of implementation and to improve the efficiency of determining the current rotation speed, the mapping relationship between the preset remaining drainage volume and the rotation speed of the laundry treatment cylinder includes: the rotation speed corresponding to the first remaining drainage volume V1 is the first rotation speed R1, the rotation speed corresponding to the second remaining drainage volume V2 is the second rotation speed R2, and the rotation speed corresponding to the third remaining drainage volume V3 is the third rotation speed R3. Among them, the first remaining drainage volume, the second remaining drainage volume, and the third remaining drainage volume increase in sequence, that is, V1 < V2 < V3, and the first rotation speed, the second rotation speed, and the third rotation speed decrease in sequence, that is, R1 > R2 > R3.

[0064] Step 104: Control the water in the laundry treatment cylinder to be discharged, and control the laundry treatment cylinder to rotate at the current rotation speed.

[0065] After determining the current rotation speed, the laundry treatment cylinder can be controlled to rotate while draining water. The rotation speed of the laundry treatment cylinder is the current rotation speed determined in step 103.

[0066] During the drainage process, the rotation of the laundry treatment drum can make the distribution of the laundry in the laundry treatment drum more uniform, avoiding the problems of low dehydration efficiency and low dehydration safety caused by eccentricity due to uneven distribution of the laundry during the subsequent dehydration process. At the same time, the laundry treatment drum rotates while draining water. Compared with the scenario where the laundry treatment drum does not rotate during drainage, it can also reduce the time for the rotation speed of the laundry treatment drum to change from zero to the required rotation speed during dehydration when entering the dehydration process, further improving the laundry treatment efficiency.

[0067] The drainage method of the laundry treatment device provided by the embodiment of the present invention includes: obtaining the current drainage duration. If the current drainage duration is less than a preset first drainage duration threshold, determining the current remaining drainage volume in the laundry treatment drum, and determining the current rotation speed of the laundry treatment drum corresponding to the current remaining drainage volume according to the current remaining drainage volume and the mapping relationship between the remaining drainage volume and the rotation speed of the laundry treatment drum. Controlling the water in the laundry treatment drum to drain, and controlling the laundry treatment drum to rotate at the current rotation speed. During the drainage process, on the one hand, only when the current drainage duration is less than the preset first drainage duration threshold, subsequent operations are performed, avoiding the problem of a long drainage process caused by performing subsequent operations in the scenario where the current drainage duration is greater than the first drainage duration threshold, and improving the laundry treatment efficiency; on the other hand, during the drainage process, controlling the water in the laundry treatment drum to drain, and at the same time controlling the laundry treatment drum to rotate at the current rotation speed, so that the laundry treatment drum rotates while draining water, which can make the distribution of the laundry in the laundry treatment drum more uniform, avoiding the problems of low dehydration efficiency and low dehydration safety caused by eccentricity due to uneven distribution of the laundry during the subsequent dehydration process, improving the laundry treatment efficiency and laundry treatment safety. At the same time, the laundry treatment drum rotates while draining water. Compared with the scenario where the laundry treatment drum does not rotate during drainage, it can also reduce the time for the rotation speed of the laundry treatment drum to change from zero to the required rotation speed during dehydration when entering the dehydration process, further improving the laundry treatment efficiency.

[0068] Figure 2 FIG. is a flowchart of another drainage method of the laundry treatment device according to the embodiment of the present invention. This embodiment is based on Figure 1 the embodiment shown and various optional implementation manners, and details other steps included in the drainage method are described in detail. As Figure 2 shown, the drainage method of the laundry treatment device provided by this embodiment includes the following steps 201 to step 211.

[0069] Step 201: Obtain the current drainage duration.

[0070] Step 202: If the current drainage duration is less than a preset first drainage duration threshold, determine the current remaining drainage volume in the laundry treatment drum.

[0071] Step 203: Determine the current rotation speed of the laundry drum corresponding to the current remaining drainage volume according to the current remaining drainage volume and the mapping relationship between the preset remaining drainage volume and the rotation speed of the laundry drum.

[0072] Step 204: Control the water in the laundry drum to be drained and control the laundry drum to rotate at the current rotation speed.

[0073] The implementation processes and technical principles of Step 201 and Step 101, Step 202 and Step 102, Step 203 and Step 103, Step 204 and Step 104 are similar and will not be elaborated here.

[0074] Step 205: After a preset duration, determine whether the water in the laundry drum has been drained completely.

[0075] Optionally, the preset duration is a preset time interval. Exemplarily, the preset duration can be 1 minute.

[0076] In one implementation, the remaining water depth can be determined by a water level switch or a water level sensor. When the remaining water depth is zero, it is determined that the water in the laundry drum has been drained completely.

[0077] In another implementation, the remaining drainage volume can be determined according to the difference between the water volume injected into the laundry drum and the water volume drained from the laundry drum. When the remaining drainage volume is zero, it is determined that the water in the laundry drum has been drained completely.

[0078] Step 206: When it is determined that the water in the laundry drum has not been drained completely, update the current drainage duration.

[0079] In Step 206, when it is determined that the water in the laundry drum has not been drained completely, it means that continuous drainage is required. Then update the current drainage duration. It can be understood that the updated current drainage duration is the sum of the current drainage duration and the preset duration.

[0080] Step 207: Use the updated current drainage duration as the new current drainage duration and return to execute the steps of Step 202.

[0081] In Step 207, use the updated current drainage duration as the new current drainage duration and return to execute the step of "if the current drainage duration is less than the preset first drainage duration threshold, then determine the current remaining drainage volume in the laundry drum".

[0082] For example, assume that the current drainage duration is 3 minutes, the first drainage duration threshold is 10 minutes, and the preset duration is 1 minute. In step 205, assume that it is determined that the water in the laundry drum has not been drained completely. In step 207, the updated current drainage duration is 4 minutes. Return to execute step 202: Since 4 minutes is less than 10 minutes, determine the current remaining drainage volume in the laundry drum. Then execute steps 203 to 207.

[0083] Step 208: When it is determined that the water in the laundry drum has been drained completely, enter the dehydration program.

[0084] When it is determined that the water in the laundry drum has been drained completely, enter the next stage of laundry processing. Exemplarily, the next stage of laundry processing can be the dehydration stage. Then in step 208, when it is determined that the water in the laundry drum has been drained completely, enter the dehydration program.

[0085] Step 209: If the current drainage duration is greater than or equal to the first drainage duration threshold, stop drainage and send a drainage anomaly message to the user.

[0086] If the current drainage duration is greater than or equal to the first drainage duration threshold, it indicates that there is a blockage or other fault in the drainage system of the laundry processing device, resulting in poor drainage. At this time, stop drainage and send a drainage anomaly message to the user.

[0087] Optionally, after sending the drainage anomaly message to the user, if a continue operation instruction triggered by the user is received, drainage can continue.

[0088] Figure 3 It is a schematic diagram of a user interface in another drainage method of a laundry processing device according to an embodiment of the present invention. As Figure 3 shown, the laundry processing device can display drainage anomaly messages such as "Drainage anomaly! The drain pipe is blocked. Please deal with it as soon as possible" in the user interface 31. The user interface 31 in this embodiment can be the user interface in the laundry processing device, for example, the display screen in the laundry processing device. The user interface 31 in this embodiment can also be the user interface of the user's terminal device, for example, the display screen of the user's mobile phone.

[0089] Step 210: When it is determined that the water in the laundry drum has been drained completely, obtain the total drainage duration.

[0090] The total drainage duration in this embodiment refers to the duration from the start of drainage to the moment when the water in the laundry drum has been drained completely. In step 210, the total drainage duration can be obtained through a timing device or a clock module.

[0091] Step 211: When the total drainage duration is less than the first drainage duration threshold and greater than or equal to the preset second drainage duration threshold, send a drainage system cleaning required message to the user so that the user can clean the drainage system according to the drainage system cleaning required message.

[0092] Among them, the first drainage duration threshold is greater than the second drainage duration threshold.

[0093] In this embodiment, the second drainage duration threshold is a value determined in advance according to empirical data. The second drainage duration threshold is used to represent the drainage duration required by the laundry treatment device in a scenario where the drainage system is not faulty but needs to be cleaned. Optionally, the second drainage duration threshold in this embodiment can be any value between 4 minutes and 7 minutes. Exemplarily, the second drainage duration threshold can be 4 minutes, 5 minutes, 6 minutes, or 7 minutes, etc.

[0094] When the total drainage duration is less than the first drainage duration threshold and greater than or equal to the preset second drainage duration threshold, it indicates that the drainage system is not faulty but needs to be cleaned at this time. Therefore, in step 211, a drainage system cleaning required message is sent to the user so that the user can clean the drainage system according to the drainage system cleaning required message.

[0095] Figure 4 FIG. is a schematic diagram of another user interface for a drainage method of a laundry treatment device according to an embodiment of the present invention. As Figure 4 shown, the laundry treatment device can display drainage system cleaning required messages such as "Poor drainage, please clean the drain pipe as soon as possible" in the user interface 41. The user interface 41 in this embodiment can be the user interface in the laundry treatment device, for example, the display screen in the laundry treatment device. The user interface 41 in this embodiment can also be the user interface of the user's terminal device, for example, the display screen of the user's mobile phone.

[0096] The laundry treatment method provided in this embodiment, on the one hand, can, when it is determined that the water in the laundry treatment drum has not been drained completely, repeatedly execute the steps of determining the current rotation speed of the laundry treatment drum corresponding to the current remaining drainage volume, controlling the water in the laundry treatment drum to drain, and controlling the laundry treatment drum to rotate at the current rotation speed, so that the laundry treatment drum drains water while rotating, further improving the laundry treatment efficiency. On the other hand, when the total drainage duration is less than the first drainage duration threshold and greater than or equal to the preset second drainage duration threshold, a drainage system cleaning required message is sent to the user, enabling the user to clean the drainage system in a timely manner, avoiding drainage system failures, and improving the subsequent laundry treatment efficiency and user experience.
