Description

Technical Field

[0001] This application relates to the field of electrical appliance technologies, and particularly to an anti-overflow control method, device, washing machine, and computer-readable storage medium. Background Art

[0002] Laundry equipment needs to fill the laundry cavity with water to enable clothes washing. Under normal circumstances, if the laundry equipment is automatically filled with water, after the water level reaches a predetermined position, the water inlet valve will be controlled to close to prevent the water level from overflowing. If the water inlet valve is damaged and cannot be automatically closed, there will be an overflow phenomenon. In addition, if the laundry equipment is manually filled with water, for example, some laundry equipment is directly connected to an external water faucet and the user manually opens the faucet to fill the water. If the user leaves and forgets to close the faucet, there will also be a phenomenon of water level overflowing.

[0003] In the prior art, the laundry equipment itself is equipped with a drain hose and the drain hose is connected to a floor drain. If there is an overflow, there is still a gap between the drain hose and the floor drain, and the overflowing water will flow into the floor drain through the gap. Thus, due to the existence of the floor drain, if water overflows from the laundry equipment, the excess water will be discharged through the floor drain, but there will still be water stains remaining on the ground. Therefore, the existing laundry equipment has not carried out relevant designs for anti-overflow. Summary of the Invention

In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but rather to be in line with the broadest scope consistent with the principles and features disclosed in the present application.

[0049] The present application provides an anti-overflow water control method, device, equipment, and storage medium, which will be described in detail below respectively.

[0050] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the scenario of the anti-overflow water control system provided by the embodiments of the present application. The anti-overflow water control system may include a washing machine 100. As Figure 1 the washing machine 100 in

[0052] It should be noted that Figure 1 the schematic diagram of the scenario of the anti-overflow water control system shown is merely an example. The anti-overflow water control system and scenario described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the anti-overflow water control system and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0053] As Figure 2 shown, Figure 2 which is a schematic flowchart of an embodiment of the anti-overflow water control method in the embodiments of the present application. The anti-overflow water control method can be applied to a target laundry device. The target laundry device includes a water inlet valve, a first water level sensor, and a drain valve, and specifically includes the following steps 201 to 203:

[0054] 201. Control the water inlet valve to close.

[0055] In an embodiment of the present application, the processor of the target laundry device issues a closing instruction to the water inlet valve according to a program. The timing of issuing the closing instruction may include: if the current water level reaches the set water level, for example, the current water level touches the sensor corresponding to the set water level, then the closing instruction is issued. Or, the user manually stops the water inlet, and at this time, the closing instruction can also be issued. Specifically, the embodiments of the present application do not limit it.

[0056] 202. Determine whether the water inlet valve is successfully closed. Among them, if the first water level sensor alarms, it is determined that the water inlet valve is closed unsuccessfully.

[0057] In an embodiment of the present application, an additional first water level sensor may be installed at the warning water level inside the laundry chamber. After issuing the instruction to control the closing of the water inlet valve, normally, if the water inlet valve is closed normally, the water level will not continue to rise. Therefore, if the water inlet valve fails to close, the water level will continue to rise. As the water level rises, the water level will touch the first water level sensor. If the water level touches the first water level sensor, the first water level sensor can send an alarm message to the processor.

[0058] 203. Control the drain valve to open to prevent water level overflow.

[0059] According to the above steps, if the processor receives the alarm message from the first water level sensor, it issues an opening instruction to the drain valve, so that the drain valve opens to drain water, thereby counteracting the problem that the water inlet valve cannot be closed, and further avoiding the problem of water level overflow.

[0060] The anti-overflow control method provided by the present application can control the closing of the water inlet valve after the water level of the laundry device reaches the established water level. Then, it can be determined whether the water inlet valve is successfully closed according to the first water level sensor. If the water inlet valve fails to close, the drain valve can be controlled to open to drain the excess water from the laundry device and avoid water overflow.

[0061] To better implement the embodiments of the present application, in an embodiment of the present application, the target laundry device includes a second water level sensor; the installation height of the second water level sensor is higher than that of the first water level sensor; controlling the drain valve to open includes:

[0062] Determine the first target alarm moment of the first water level sensor and determine the second target alarm moment of the second water level sensor; determine the target duration according to the first target alarm moment and the second target alarm moment; determine the current water level rising rate according to the target duration and the target height difference between the second water level sensor and the first water level sensor; control the opening degree of the drain valve according to the current water level rising rate.

[0063] The above embodiments provide a solution to prevent water level overflow by controlling the opening of the drain valve. However, in some cases, after the inlet valve receives a closing instruction, it may be in a semi-closed state, and at this time, the water level rises slowly; or, after the inlet valve receives a closing instruction, it may also be in a fully open state, and at this time, the water level rises quickly. Therefore, the rate of water level rise is also different. If the drain valve is controlled to open without controlling its opening degree, it may cause the water to drain too quickly, and then, if the user resolves the abnormality of the inlet valve, re-filling of water is required again.

[0064] Based on this, in the embodiments of the present application, the opening degree of the drain valve can be further controlled, so as to achieve the effect that the water inflow is equal to the water drainage, and further solve the problem of keeping the water level basically unchanged. If the user completes the troubleshooting of the inlet valve and completes the repair subsequently, there is no need to re-fill the water.

[0065] In the embodiments of the present application, since the model of the inlet valve is fixed, the water inlet rate can be determined for each additional degree of opening. Therefore, after installing the second water level sensor, if the drain valve is opened and the water level continuously rises to the position of the second drain valve, the target duration between the two alarm times can be determined according to the first alarm time and the second alarm time. At the same time, based on the target height difference between the two sensors, the rising rate of the water level can be calculated, and then the current water inlet rate can be known. Since the water inlet rate can be determined for each additional degree of opening, at this time, by reverse deduction, the current opening degree of the inlet valve can be known. At this time, if the drain valve and the inlet valve have the same specifications, the drain valve can be controlled to open with the same opening degree. Or, if the inlet valve and the drain valve have different specifications, the opening degree of the drain valve can be controlled according to the actual situation, for example, by measuring in advance the drainage rate for each degree of opening of the drain valve, and then determining the opening degree at which the drainage rate is the same as the water inlet rate.

[0066] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target laundry device further includes a third water level sensor; the installation height of the third water level sensor is higher than the installation height of the second water level sensor; after controlling the opening degree of the drain valve according to the current water level rising rate, the method further includes:

[0067] If the opening degree of the drain valve controlled is the maximum opening degree and the third water level sensor alarms, a first target alarm message is generated to notify the user to manually stop the water supply.

[0068] The above embodiments provide a solution to prevent water overflow by controlling the opening of the drain valve. In actual situations, after the drain valve is opened to the maximum angle, the drainage volume reaches the maximum. If an extreme situation occurs, such as a water pipe break and water directly enters by bypassing the inlet valve, the water inflow may exceed the water inflow volume corresponding to the maximum opening degree of the inlet valve. Therefore, it is possible that the drain valve cannot meet the drainage requirement, and there is still a risk of water overflow.

[0069] Based on this, for this extreme case, the third water level sensor is also provided in the embodiment of the present application for this situation. Specifically, if the opening degree of the drain valve is the largest and the water level still rises to the position of the third water level sensor, it can be determined at this time that the drainage means of the drain valve fails. At this time, the processor of the laundry equipment can generate a first target warning message, and the first target warning message can be a warning message for notifying the user to close the household water valve. The form of the first target warning message is not limited. For example, corresponding text information can be generated and notified to the user to manually cut off the water supply, such as closing the household water valve, etc., through the wifi module of the laundry equipment, through the APP or by text message. Or, it can also be that the speaker of the laundry equipment emits audio information to notify the user to close the household water valve, etc.

[0070] In order to better implement the embodiment of the present application, in one embodiment of the present application, determining whether the water inlet valve is successfully closed includes:

[0071] Execute timing to obtain a target timing duration; if the target timing duration is greater than the target duration threshold and the first water level sensor does not give an alarm, it is determined that the water inlet valve is successfully closed; if the target timing duration is less than or equal to the target duration threshold and the first water level sensor gives an alarm, it is determined that the water inlet valve is closed unsuccessfully.

[0072] The above embodiment provides a solution for determining whether the water inlet valve is successfully closed according to the first water level sensor. In the actual application process, if the water inlet valve is successfully closed, there will be no situation of reopening before the opening instruction. Therefore, if the water inlet valve is continuously detected for whether it is closed, it will waste the computing resources of the processor. Especially after the laundry equipment integrates more and more functions, including the Internet of Things or neural network models, it is more important to save the computing resources of the processor.

[0073] Based on this, after the closing instruction is issued, if the water level still does not rise to the position of the first water level sensor after a period of time, it can be determined that the closing is successful and there is no need to monitor anymore. Therefore, after the processor issues the closing instruction for the water inlet valve, timing can be started to obtain a target timing duration. If the first water level sensor still does not give an alarm after the target timing duration, it can be determined that it is successfully closed.

[0074] Specifically, the washing machine starts to fill with water, and at the same time, the water level sensor senses the water level. When the water level has not reached the specified water level, the drain valve is always open, and water continuously enters the sample cylinder; when the water level reaches the specified water level, the drain valve closes, and water intake into the sample cylinder stops. Starting from the water cut-off time, a 30-second timer is started. If the water level has not reached the 9th gear (the water level gear corresponding to the first water level sensor), the washing machine continues to operate normally until the end; if the water level reaches the 9th gear, it is determined that the "drain valve stops water intake" instruction has not caused the drain valve to perform an effective closing action, a drain valve failure alarm is given, and at the same time, the drain valve is opened to drain water to prevent excessive water from overflowing to the ground. The drain valve remains in the open state until the user actively pauses the program.

[0075] To better implement the embodiments of the present application, in one embodiment of the present application, after determining whether the water inlet valve has been successfully closed, the method further includes:

[0076] If the water inlet valve is successfully closed, execute the target laundry process.

[0077] In the embodiments of the present application, the target laundry process may include any washing process, such as dry cleaning, wool washing mode, silk washing mode, quick washing mode, etc. Specifically, it can be executed according to the user's setting or according to the program's setting, and the embodiments of the present application do not limit it.

[0078] To better implement the embodiments of the present application, in one embodiment of the present application, before controlling the water inlet valve to close, the method further includes:

[0079] Detect whether the user-set water level has been obtained; if the user-set water level has been obtained, control the water inlet valve to open so that the water level reaches the user-set water level; if the user-set water level has not been obtained, weigh the laundry cavity to determine the current weight information; according to the current weight information, determine the target washing water level; control the water inlet valve to open so that the water level reaches the target washing water level.

[0080] In the above embodiments, multiple implementation methods for preventing water overflow are provided. Before controlling the water inlet valve to close, the embodiments of the present application also provide a solution for controlling the water inlet of the water inlet valve.

[0081] Among them, the user-set water level can be obtained according to the operations of the user on the APP of the laundry device or the control panel of the laundry device. The embodiments of the present application do not limit it. In addition, the user-set water level can also be obtained according to historical records. For example, if the user selects Mode A to wash clothes, and if the user has set the water level in Mode A and the current user has not reset the water level, then the historical set water level corresponding to Mode A can be obtained as the user-set water level; or, for example, if the user selects Mode B to wash clothes, and if the user has set the water level in Mode B and the current user has not reset the water level, then the historical set water level corresponding to Mode B can be obtained as the user-set water level. Of course, it can also include Mode C, Mode D, etc., which will not be elaborated here.

[0082] After obtaining the user-set water level, the processor can issue an opening instruction for the water inlet valve until the water inlet valve is closed.

[0083] Alternatively, the laundry device also has a weighing function. If there is no user-set water level, at this time, the laundry device can adapt a suitable water level according to the weight of the clothes. For example, multiple clothes weight ranges can be preset in advance, and each clothes weight range corresponds to a water level. After obtaining the current weight information by weighing the current clothes, determine which specific target clothes weight range the current weight information belongs to, and according to the water level corresponding to the target clothes weight range.

[0084] In order to better implement the embodiments of the present application, in one embodiment of the present application, if the first water level sensor alarms and it is determined that the control of closing the water inlet valve fails, the method further includes:

[0085] Generate a second target alarm message to inform the user that there is a water overflow phenomenon; if a target operation instruction issued by the user is obtained, execute the corresponding control process according to the target operation instruction.

[0086] The above embodiment provides a solution for the processor to generate a first target alarm message, which is used to inform the user to block the water source. In the embodiments of the present application, a solution for generating a second target alarm message is also provided.

[0087] Among them, the purpose of the second target alarm message is to inform the user that there is a water overflow phenomenon, but it is not a serious water overflow and is still in the controllable stage of the drain valve. For example: the second target alarm message can be information indicating that there is a water overflow phenomenon. The form of the second target alarm message is not limited. For example, corresponding text information can be generated and notified of the water overflow phenomenon through the wifi module of the laundry device, in the form of an APP notification or a text message. Or, it can also be that the speaker of the laundry device emits audio information to notify the user that there is a water overflow phenomenon.

[0088] At this time, after the user obtains the second target warning information, there may be control operations for the laundry equipment. For example: shutting down the laundry equipment, or restarting the laundry equipment, etc. These instructions all belong to the target operation instructions. Therefore, if the target operation instruction issued by the user is obtained subsequently, it can be responded to and executed.

[0089] To better implement the anti-overflow control method in the embodiments of the present application, on top of the anti-overflow control method, an anti-overflow control device is also provided in the embodiments of the present application. This device is applied to the target laundry equipment, and the target laundry equipment includes a water inlet valve, a first water level sensor, and a drain valve, as Figure 3 shown, the device 300 includes:

[0090] A control module 301, configured to control the water inlet valve to close;

[0091] A determination module 302, configured to determine whether the water inlet valve is successfully closed. Among them, if the first water level sensor gives an alarm, it is determined that the water inlet valve fails to close;

[0092] The control module 301 is further configured to control the drain valve to open to prevent water level overflow.

[0093] The anti-overflow control device provided by the present application can, after the water level of the laundry equipment reaches the established water level, control the water inlet valve to close through the control module 301. Then, the determination module 302 can determine whether the water inlet valve is successfully closed according to the first water level sensor. If the water inlet valve fails to close, the control module 301 can control the drain valve to open to drain the excess water from the laundry equipment and avoid water overflow.

[0094] In some embodiments of the present application, the target laundry equipment includes a second water level sensor; the installation height of the second water level sensor is higher than the installation height of the first water level sensor. The control module 301 is specifically configured to:

[0095] Determine the first target alarm moment of the first water level sensor and determine the second target alarm moment of the second water level sensor;

[0096] Determine the target duration according to the first target alarm moment and the second target alarm moment;

[0097] Determine the current water level rising rate according to the target duration and the target height difference between the second water level sensor and the first water level sensor;

[0098] Control the opening degree of the drain valve according to the current water level rising rate.

[0099] In some embodiments of the present application, the target laundry equipment further includes a third water level sensor; the installation height of the third water level sensor is higher than the installation height of the second water level sensor;

[0100] After controlling the opening degree of the drain valve according to the current water level rising rate, the control module 301 is further specifically configured to:

[0101] If the opening degree of the drain valve is controlled to be the maximum opening degree and the third water level sensor alarms, generate a first target alarm message to notify the user to cut off the water supply manually.

[0102] In some embodiments of the present application, the determining module 302 is specifically configured to:

[0103] Execute timing to obtain a target timing duration;

[0104] If the target timing duration is greater than the target duration threshold and the first water level sensor does not alarm, determine that the water inlet valve is successfully closed;

[0105] If the target timing duration is less than or equal to the target duration threshold and the first water level sensor alarms, determine that the water inlet valve is closed unsuccessfully.

[0106] In some embodiments of the present application, after determining whether the water inlet valve is successfully closed, the control module 301 is further specifically configured to:

[0107] If the water inlet valve is successfully closed, execute a target laundry process.

[0108] In some embodiments of the present application, before controlling the water inlet valve to close, the control module 301 is further specifically configured to:

[0109] Detect whether the user-set water level is obtained;

[0110] If the user-set water level is obtained, control the water inlet valve to open so that the water level reaches the user-set water level;

[0111] If the user-set water level is not obtained, weigh the laundry chamber to determine the current weight information;

[0112] Determine a target washing water level according to the current weight information;

[0113] Control the water inlet valve to open so that the water level reaches the target washing water level.

[0114] In some embodiments of the present application, if the first water level sensor alarms and it is determined that the control of closing the water inlet valve fails, the control module 301 is further specifically configured to:

[0115] Generate a second target alarm message to inform the user that there is a water overflow phenomenon;

[0116] If a target operation instruction issued by the user is obtained, execute a corresponding control process according to the target operation instruction.

[0117] An embodiment of the present application further provides a washing machine, which includes a processor, a memory, and a computer program stored in the memory and executable on the processor. The processor executes the computer program to implement the steps in any one of the anti-overflow control methods in the embodiments of the present application. Among them, the washing machine integrates any one of the anti-overflow control methods provided in the embodiments of the present application, such as Figure 4 As shown, it shows a schematic structural diagram of the washing machine involved in the embodiments of the present application. Specifically:

[0118] The washing machine may include components such as a processor 401 with one or more processing cores, a memory 402 with one or more computer-readable storage media, a power supply 403, and an input unit 404. Those skilled in the art can understand that Figure 4 the washing machine structure shown in does not constitute a limitation on the washing machine, and it may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0119] Among them:

[0120] The processor 401 is the control center of the washing machine, connecting various parts of the entire washing machine through various interfaces and lines. By running or executing software programs and / or modules stored in the memory 402, and calling data stored in the memory 402, it executes various functions of the washing machine and processes data, thereby monitoring the washing machine as a whole. Optionally, the processor 401 may include one or more processing cores; the processor 401 may be a central processing unit (CPU), or it may also be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), off-the-shelf programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc. Preferably, the processor 401 may integrate an application processor and a modulation and demodulation processor. Among them, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modulation and demodulation processor mainly processes wireless communication. It can be understood that the above modulation and demodulation processor may not be integrated into the processor 401 either.

[0121] The memory 402 can be used to store software programs and modules.
