Technical Field

[0001] The embodiments of the present invention relate to the technical field of household appliances, and particularly to a drainage control method, device, computer device, and storage medium. Background Art

[0002] With the improvement of people's living standards and the development of home appliance production technology, people have put forward more requirements for household appliances. At present, in order to save space and resources, multiple washing devices share a drainage pipe to achieve the drainage function, thereby reducing the problem of increased floor area caused by laying drainage pipes separately for multiple washing devices.

[0003] However, during the drainage process of sharing a drainage pipe, if the drainage volume of one device is too large, the drainage speed is too fast, or the drainage pipe is blocked, sewage may enter other devices, that is, the backflow phenomenon occurs, which affects the normal operation of other devices and even causes damage to the devices. Summary of the Invention

Finally, the drainage parameters of the target washing device are adjusted according to the drainage parameter adjustment amount, and the target washing device drains water according to the adjusted drainage parameters to reduce the sewage backflow amount of the backflow washing device, thereby reducing the situation of equipment damage. In addition, since the present invention can adjust the drainage parameters of the target washing device according to the drainage parameter adjustment amount to reduce the sewage backflow amount of the backflow washing device, it solves the problem of backflow phenomenon when multiple devices share a drainage pipeline, which affects the normal operation of other devices and even causes equipment damage.

[0034] In the description of the present application, unless otherwise specified, the meaning of "a plurality" refers to two or more than two.

[0035] Figure 1 FIG. is a schematic flowchart of a drainage control method provided by the present invention. This embodiment is applicable to the situation where a plurality of washing devices share a drainage pipeline. This method can be executed by a drainage control device provided by the present invention, and the device can be implemented in a software and / or hardware manner. Specifically, the device can be integrated in a computer device. The computer device is connected to at least two washing devices through a wireless network to achieve remote control of at least two washing devices, including operations such as starting, stopping, and setting parameters. Exemplarily, the computer device can be a computer, a server, or a base station. Refer to Figure 1 Accordingly, the drainage control method of this embodiment can specifically include the following steps:

[0036] Step 110, obtain the drainage status and sewage water level status of each of at least two washing devices.

[0037] Specifically, the washing device is a device with a washing function. At least two washing devices can be devices of the same type or different types. Examples of device types include: washing machines, floor washers, dishwashers, etc. The embodiments of the present invention do not limit this. The drainage status includes a drainage open status or a drainage closed status. The sewage water level status includes a sewage water level rising status, a sewage water level unchanged status, or a sewage water level falling status.

[0038] In specific implementation, after at least one washing device starts to execute a drainage task, the drainage status and sewage water level status corresponding to each washing device can be obtained through sensors equipped with each washing device. Among them, the sensor can be a contact liquid level sensor or a non-contact liquid level sensor. The embodiments of the present invention do not limit this.

[0039] In this embodiment, by obtaining the drainage status and sewage water level status of each of at least two washing devices, it helps to determine the backflow washing device and the target washing device.

[0040] Step 120, determine the washing device that has experienced sewage backflow from at least two washing devices according to the drainage status and sewage water level status of each washing device, to obtain the backflow washing device. The washing devices other than the backflow washing device among at least two washing devices are target washing devices.

[0041] In a specific implementation, after obtaining the drainage status and the sewage water level status of each washing device, the washing device with sewage backflow, i.e., the backflow washing device, can be determined according to the drainage status and the sewage water level status of each washing device. For example, if the drainage status of a certain washing device is the drainage closed state, and when its sewage water level continuously rises, that is, the sewage water level status is the sewage water level rising state, it indicates that sewage backflow has occurred in this device, and this device is confirmed as the backflow washing device. Then, the washing devices other than the backflow washing device are determined as the target washing devices.

[0042] In this embodiment, by determining the backflow washing device and the target washing devices, it helps to reduce the amount of sewage backflow later.

[0043] Step 130: Determine the adjustment amount of the drainage parameters of the target washing device.

[0044] Specifically, the drainage parameters are the parameters that can affect the drainage volume of the washing device. Exemplarily, the drainage parameters can be the drainage duration, the drainage flow rate, the drainage valve opening degree, and / or the drainage frequency, etc. The embodiments of the present invention do not limit this. Among them, the longer the drainage duration, the larger the drainage flow rate, the larger the drainage valve opening degree, or the higher the drainage frequency of the washing device, the larger the drainage volume of the washing device.

[0045] In a specific implementation, the adjustment amount of the drainage parameters of the target washing device can be determined according to a preset ratio. Exemplarily, the drainage parameters are the drainage duration and the drainage valve opening degree, and the preset ratio is 50%. Assuming that the current drainage duration is 60 s per minute and the drainage valve opening degree is 360 degrees, after determining the adjustment amount of the drainage parameters of the target washing device according to the preset ratio, it can be determined that the drainage duration adjustment amount is 30 s and the drainage valve opening degree adjustment amount is 180 degrees.

[0046] In this embodiment, by determining the adjustment amount of the drainage parameters of the target washing device, it assists in completing the task of reducing the amount of sewage backflow.

[0047] Step 140: Adjust the drainage parameters of the target washing device according to the adjustment amount of the drainage parameters to reduce the amount of sewage backflow into the backflow washing device.

[0048] In a specific implementation, the drainage parameters of the target washing device are adjusted according to the previously determined adjustment amount of the drainage parameters, and then the target washing device performs the drainage task with the adjusted drainage parameters. Exemplarily, assuming that the drainage parameters are the drainage valve opening duration and the drainage valve opening degree, the current drainage valve opening duration is 60 s per minute, that is, always open, and the drainage valve opening degree is 360 degrees. The adjustment amount of the drainage parameters of the target washing device is that the drainage duration adjustment amount is 30 s and the drainage valve opening degree adjustment amount is 180 degrees. The adjusted drainage parameters of the target washing device are 30 s per minute and the drainage valve opening degree is 180 degrees.

[0049] In this embodiment, the target washing device drains water according to the adjusted drainage parameters to reduce the amount of sewage backflow into the washing device.

[0050] In an embodiment of the present invention, after at least one washing device starts to perform the drainage task, first obtain the drainage status and sewage water level status of each of at least two washing devices. By obtaining the drainage status and sewage water level status of each of at least two washing devices, it helps to determine the backflow washing device and the target washing device; then determine the washing device that has experienced sewage backflow from at least two washing devices according to the drainage status and sewage water level status of each washing device to obtain the backflow washing device, and then determine the washing devices other than the backflow washing device among at least two washing devices as the target washing device. By determining the backflow washing device and the target washing device, it provides help for reducing the amount of sewage backflow later; then determine the adjustment amount of the drainage parameters of the target washing device. By determining the adjustment amount of the drainage parameters of the target washing device, it assists in completing the task of reducing the amount of sewage backflow; finally, adjust the drainage parameters of the target washing device according to the adjustment amount of the drainage parameters. The target washing device drains water according to the adjusted drainage parameters to reduce the amount of sewage backflow into the backflow washing device, thereby reducing the situation of equipment damage. In addition, since the present invention can adjust the drainage parameters of the target washing device according to the adjustment amount of the drainage parameters to reduce the amount of sewage backflow into the backflow washing device, it solves the problem of backflow when multiple devices share a drainage pipeline, which affects the normal operation of other devices and even causes equipment damage.

[0051] Figure 2 It is another flowchart of the drainage control method provided by the present invention. This embodiment is a specific implementation based on the above embodiment. As Figure 2 shown, the method of this embodiment may specifically include the following steps:

[0052] Step 210, obtain the drainage status and sewage water level status of each of at least two washing devices.

[0053] Step 211, determine whether there is a washing device in the drainage closed state among at least two washing devices. If so, execute step 212; if not, execute step 215.

[0054] In specific implementation, after at least one washing device starts to perform the drainage task, by determining whether there is a washing device in the drainage closed state among at least two washing devices, it helps to confirm whether the washing device has experienced backflow.

[0055] Step 212, determine the washing device in the drainage closed state as a non-working device.

[0056] In a specific implementation, after determining that there is a washing device in a drainage closed state among at least two washing devices, the washing device in the drainage closed state is determined as a non-operating device.

[0057] Exemplarily, assume there are four washing devices A, B, C, and D. If devices A, B, and C are in a drainage open state and device D is in a drainage closed state, then device D is determined as a non-operating device.

[0058] Step 213, obtain the sewage water level state of the non-operating device.

[0059] Specifically, the sewage water level state includes a sewage water level rising state, a sewage water level unchanged state, or a sewage water level falling state.

[0060] In a specific implementation, the sewage water level state of the non-operating device can be obtained by acquiring the value of the sewage water level sensor of the non-operating device.

[0061] Exemplarily, assume that washing device D is a non-operating device, and then obtain the value of the sewage water level sensor of washing device D. If the value is greater than zero, it can be determined that the sewage water level state of washing device D is a sewage water level rising state.

[0062] In this embodiment, by obtaining the sewage water level state of the non-operating device, a judgment basis is provided for determining whether the non-operating device is a backflow washing device later.

[0063] Step 214, determine the non-operating device with a rising sewage water level state as a backflow washing device.

[0064] Exemplarily, after determining that the sewage water level state of non-operating device D is a sewage water level rising state, it can be determined that washing device D is a backflow washing device.

[0065] Step 215, obtain the sewage water level state of each washing device.

[0066] In a specific implementation, after determining that there is no washing device in a drainage closed state among at least two washing devices, the sewage water level state of each washing device can be obtained by acquiring the value of the sewage water level sensor corresponding to each washing device.

[0067] Exemplarily, assume there are four washing devices A, B, C, and D. Now, all four washing devices are draining water, so it can be determined that all four washings are in a drainage open state, that is, there is no washing device in a drainage closed state. Then, obtain the value of the sewage water level sensor corresponding to each device, perform a difference calculation with the value obtained at the previous moment, determine the device with a result greater than zero as a sewage water level rising state, the device with a result equal to zero as a sewage water level unchanged state, and the device with a result less than zero as a sewage water level falling state.

[0068] In this embodiment, by obtaining the sewage water level status of each washing device, a judgment basis is provided for determining the washing devices with backflow later.

[0069] Step 216: Determine the washing devices with the sewage water level rising state and / or the sewage water level remaining unchanged state among at least two washing devices as the washing devices with backflow.

[0070] In specific implementation, after determining that there is no washing device in the drainage closed state among at least two washing devices, obtain the sewage water level status of each washing device. Since all current devices are in the drainage open state, when the sewage water level of a device does not drop, that is, the sewage water level rises or remains unchanged, it means that there is backflow in this device. Therefore, determine the washing devices with the sewage water level rising state and / or the sewage water level remaining unchanged state among the washing devices as the washing devices with backflow.

[0071] Exemplarily, assume that there are four washing devices A, B, C, and D. Now, these four washing devices are all performing drainage operations. The sewage water level status of device A is the sewage water level dropping state, the sewage water level status of device B is the sewage water level dropping state, the sewage water level status of device C is the sewage water level remaining unchanged state, and the sewage water level status of device D is the sewage water level rising state. Then, determine device C and device D as the washing devices with backflow.

[0072] Step 217: Use the washing devices other than the washing devices with backflow among at least two washing devices as the target washing devices.

[0073] Exemplarily, assume that there are currently four washing devices A, B, C, and D. Among them, device C and device D are the washing devices with backflow. Then, the target washing devices are A and B.

[0074] Step 218: Obtain the sewage backflow volume of the washing device with backflow.

[0075] In specific implementation, the current water level value obtained from the sewage water level sensor of the washing device with backflow and the water level value at the previous moment can be used to calculate the difference between the two, and the sewage backflow volume of the washing device with backflow can be determined.

[0076] Exemplarily, assume that the current sewage water level value of the washing device with backflow is 80 cm, the sewage water level value at the previous moment is 50 cm, and the diameter of the drainage pipe of the washing device with backflow is 10 cm. The sewage backflow volume of the washing device with backflow can be obtained as 2.36 liters.

[0077] In this embodiment, by obtaining the sewage backflow volume of the washing device with backflow, a data basis is provided for determining the adjustment amount of the drainage parameters of the target washing device later.

[0078] Step 219: Determine the adjustment amount of the drainage parameters of the target washing device according to the sewage backflow volume.

[0079] Specifically, the drainage parameter can be the opening duration of the drainage valve, the drainage flow rate, the opening degree of the drainage valve, and / or the drainage frequency, etc. The embodiments of the present invention do not limit this. Among them, the larger the amount of sewage backflow, the more the drainage volume of the target washing device needs to be reduced. And the longer the opening duration of the drainage valve, the larger the drainage flow rate, the larger the opening degree of the drainage valve, or the higher the drainage frequency, the larger the drainage volume of the washing device. Therefore, when the amount of sewage backflow is larger, the drainage parameters of the target washing device that are positively correlated with the drainage volume should be smaller, such as: the opening duration of the drainage valve, the drainage flow rate, the opening degree of the drainage valve, and the drainage frequency.

[0080] In specific implementation, after determining the amount of sewage backflow, the adjustment target can be determined according to the amount of sewage backflow, and then the specific adjustment amount can be calculated according to the adjustment target. Finally, according to the calculated adjustment amount, the drainage parameters of the target washing device are actually adjusted.

[0081] Further, there are at least two target washing devices. Determining the drainage parameter adjustment amount of the target washing device according to the amount of sewage backflow includes:

[0082] Obtaining the drainage configuration information of each target washing device;

[0083] Determining the drainage parameter adjustment amount of the corresponding target washing device according to the amount of sewage backflow and the drainage configuration information of each target washing device.

[0084] Specifically, the drainage configuration information is information that can control the drainage volume of the washing device. Exemplarily, the drainage configuration information can be the specification of the drainage pipeline, the pump parameters, and / or the drainage valve configuration, etc. The embodiments of the present invention do not limit this. Among them, the larger the diameter of the drainage pipeline, the larger the power of the pump, or the larger the opening degree of the drainage valve, the larger the drainage volume of the corresponding washing device.

[0085] In specific implementation, after obtaining the amount of sewage backflow of the backflow washing device, the drainage configuration information of each target washing device can be obtained first, and then the drainage parameter adjustment amount of the corresponding target washing device can be determined according to the amount of sewage backflow and the drainage configuration information of each target washing device.

[0086] Exemplarily, assume that there are two devices, A and B, as the target washing devices, the drainage parameter is the opening degree of the drainage valve. The drainage configuration information of device A is that the diameter of the drainage pipeline is 10 cm and the opening degree of the drainage valve is 360 degrees; the drainage configuration information of device B is that the diameter of the drainage pipeline is 5 cm and the opening degree of the drainage valve is 360 degrees; the amount of sewage backflow is 1 liter. Then the drainage parameter adjustment amount of device A can be 180 degrees, and the drainage parameter adjustment amount of device B can be 120 degrees.

[0087] In this embodiment, according to the sewage backflow volume and the drainage configuration information of each target washing device, the adjustment amount of the drainage parameters of the corresponding target washing device can be determined more accurately.

[0088] Step 220, determine the adjustment amount of the drainage parameters of the target washing device in the current period.

[0089] Specifically, the current period is a period set according to the actual situation or requirements for monitoring the drainage state and the sewage water level state of the washing device. Exemplarily, the period can be 1 minute, 2 minutes, or 4 minutes, and the embodiments of the present invention do not limit this.

[0090] In specific implementation, the adjustment amount of the drainage parameters of the target washing device in the current period can be determined according to a preset adjustment rule. For example, the drainage parameters are the opening duration of the drainage valve and the opening degree of the drainage valve. The current opening duration of the drainage valve is 60 s per minute, that is, always open, and the opening degree of the drainage valve is 360 degrees. The preset adjustment rule is that the adjustment amount of the drainage parameter is 1 / 3 of the current drainage parameter value. Then the adjustment amounts of the drainage parameters are 20 s and 120 degrees respectively. Among them, the drainage volume corresponding to the adjustment amount of the drainage parameters of the target washing device in the current period is less than the drainage volume corresponding to the adjustment amount of the drainage parameters of the target washing device in the previous period.

[0091] Step 221, adjust the drainage parameters of the target washing device according to the adjustment amount of the drainage parameters to reduce the sewage backflow volume into the washing device.

[0092] Further, within a preset number of periods, after adjusting the drainage parameters of the target washing device according to the adjustment amount of the drainage parameters of the target washing device in the current period, obtain the drainage state and the sewage water level state of the washing device with backflow;

[0093] If the drainage state of the washing device with backflow is the drainage closed state and the sewage water level state is the sewage water level rising state, then adjust the target washing device to the drainage closed state and send a drainage blockage prompt message to the user terminal;

[0094] If the drainage state of the washing device with backflow is the drainage open state, and the sewage water level state is the sewage water level rising state and / or the sewage water level unchanged state, then adjust the target washing device to the drainage closed state until the washing device with backflow is in the drainage closed state, and then adjust the target washing device to the drainage open state.

[0095] Specifically, the preset number is the number of times of adjusting the drainage parameters set according to the time situation or requirements.

[0096] In a specific implementation, after adjusting a preset number of cycles, the drainage state and the sewage water level state of the backflow washing device are obtained. If the drainage state of the backflow washing device is the drainage closed state and the sewage water level state is the sewage water level rising state, it means that the drainage pipe is blocked. Therefore, the target washing device is adjusted to the drainage closed state, and a drainage blockage prompt message is sent to the user terminal. For example, assume that the target washing device is Device A, the backflow washing device is Device B, and the preset number is 2. After adjusting the drainage parameters 2 times, if the drainage state of Device B is the drainage closed state and the sewage water level state is the sewage water level rising state, it means that backflow still occurs in Device B. Stop the drainage task of Device A and send a drainage blockage prompt message to the user terminal, such as: "There is a current drainage failure, Device A stops working. Please check the drainage pipe."

[0097] If the drainage state of the backflow washing device is the drainage open state, and the sewage water level state is the sewage water level rising state and / or the sewage water level remains unchanged state, it means that backflow still occurs in the backflow washing device, that is, the previous measures are ineffective. Therefore, the target washing device is adjusted to the drainage closed state until the backflow washing device is in the drainage closed state, and then the target washing device is adjusted to the drainage open state. For example, assume that the target washing device is Device A, the backflow washing device is Device B, and the preset number is 2. After adjusting the drainage parameters 2 times, if the drainage state of Device B is the drainage open state and the sewage water level state is the sewage water level remains unchanged state, it means that backflow still occurs in Device B. Stop the drainage task of Device A until Device B finishes the drainage task.

[0098] Therefore, after at least one washing device starts to execute the drainage task, the technical solution of the present invention first obtains the drainage status and sewage water level status of each of at least two washing devices, and then determines whether there is a washing device in the drainage closed state among the at least two washing devices, so as to help confirm whether the washing device is backflowing. If there is a washing device in the drainage closed state, the washing device in the drainage closed state is determined as a non-working device, and the sewage water level status of the non-working device is obtained, which provides a judgment basis for determining whether the non-working device is a backflow washing device. Then, the non-working device with the sewage water level rising state is determined as the backflow washing device. If there is no washing device in the drainage closed state, the sewage water level status of each washing device is directly obtained, which provides a judgment basis for determining the backflow washing device. Then, the washing device with the sewage water level rising state and / or the sewage water level unchanged state among the at least two washing devices is determined as the backflow washing device. Finally, the washing devices other than the backflow washing devices among the at least two washing devices are used as the target washing devices. By determining the backflow washing devices and the target washing devices, it helps to reduce the amount of sewage backflow in the future. Then, the sewage backflow amount of the backflow washing device can be obtained to determine the drainage parameter adjustment amount of the target washing device, or the drainage parameter adjustment amount of the target washing device in the current cycle can be determined to assist in completing the task of reducing the sewage backflow amount; finally, the drainage parameters of the target washing device are adjusted according to the drainage parameter adjustment amount, and the target washing device drains water according to the adjusted drainage parameters to reduce the sewage backflow amount of the backflow washing device, thereby reducing the situation of equipment damage. In addition, since the present invention can adjust the drainage parameters of the target washing device according to the drainage parameter adjustment amount to reduce the sewage backflow amount of the backflow washing device, it solves the problem of backflow when multiple devices share a drainage pipeline, which affects the normal operation of other devices and even causes equipment damage.

[0099] Exemplarily, there are 3 existing washing devices, namely device A, B, and C. Device A is a washing machine, device B is a floor washer, and device C is a dishwasher. The drainage parameters are the drainage valve opening time, the drainage valve closing time, and the drainage valve opening degree. The preset cycle is 2 minutes, and the preset adjustment times are 2.

[0100] 1. When the washing machine is in the drainage - on state and the floor washer and the dishwasher are in the drainage - off state, obtain the sewage water - level status of the floor washer and the dishwasher. If the sewage water - level status of the floor washer and / or the dishwasher is in the rising state of the sewage water level, it indicates that there is a back - flow phenomenon. It is necessary to adjust the drainage parameters of the washing machine and determine the washing machine as the target washing device. The current drainage - valve opening time of the washing machine is 60 s per minute of opening, the drainage - valve closing time is 0 s per minute of closing, and the drainage - valve opening degree is 360 degrees. Then, the drainage - valve opening time of the washing machine can be adjusted to 50 s per minute of opening, the drainage - valve closing time can be adjusted to 10 s per minute of closing, and the drainage - valve opening degree can be adjusted to 300 degrees. After 2 minutes, obtain the sewage water - level status of the floor washer and the dishwasher again. If the sewage water - level status of the floor washer and / or the dishwasher is in the rising state of the sewage water level, it indicates that there is still a back - flow phenomenon. It is necessary to continue to adjust the drainage parameters of the washing machine and determine the washing machine as the target washing device. The current drainage - valve opening time of the washing machine is 50 s per minute of opening, the drainage - valve closing time is 10 s per minute of closing, and the drainage - valve opening degree is 300 degrees. Then, the drainage - valve opening time of the washing machine can be adjusted to 30 s per minute of opening, the drainage - valve closing time can be adjusted to 30 s per minute of closing, and the drainage - valve opening degree can be adjusted to 180 degrees. After 2 minutes, obtain the sewage water - level status of the floor washer and the dishwasher again. If the sewage water - level status of the floor washer and / or the dishwasher is in the rising state of the sewage water level, it indicates that there is still a back - flow phenomenon. At this time, turn off the drainage function of the washing machine, adjust the washing machine to the drainage - off state, and send a drainage - blockage prompt message to the user terminal.

[0101] 2. When the washing machine, floor washer, and dishwasher are all in the drainage - open state, obtain the sewage water - level status of the washing machine, floor washer, and dishwasher. If the sewage water - level status of the dishwasher is the sewage - water - level - rising state or the sewage - water - level - unchanged state, it indicates that a back - flow phenomenon occurs, and the drainage parameters of the washing machine and floor washer need to be adjusted. The washing machine and floor washer are determined as the target washing devices. Currently, the drainage - valve opening time of both the washing machine and the floor washer is 60 s per minute, the drainage - valve closing time is 0 s per minute, the drainage - valve opening degree is 360 degrees. The diameter of the drainage pipe of the washing machine is 10 cm, and the diameter of the drainage pipe of the floor washer is 5 cm. Then, the drainage - valve opening time of the washing machine can be adjusted to 30 s per minute, the drainage - valve closing time can be adjusted to 30 s per minute, and the drainage - valve opening degree can be adjusted to 180 degrees; the drainage - valve opening time of the floor washer can be adjusted to 50 s per minute, the drainage - valve closing time can be adjusted to 10 s per minute, and the drainage - valve opening degree can be adjusted to 300 degrees. After 2 minutes, obtain the sewage water - level status of the dishwasher again. If the sewage water - level status of the dishwasher is the sewage - water - level - rising state or the sewage - water - level - unchanged state, it indicates that the back - flow phenomenon still occurs, and the drainage parameters of the washing machine and floor washer need to be continuously adjusted. The washing machine and floor washer are determined as the target washing devices. Currently, the drainage - valve opening time of the washing machine is 30 s per minute, the drainage - valve closing time is 30 s per minute, and the drainage - valve opening degree is 180 degrees; the drainage - valve opening time of the floor washer is 50 s per minute, the drainage - valve closing time is 10 s per minute, and the drainage - valve opening degree is 300 degrees. Then, the drainage - valve opening time of the washing machine can be adjusted to 20 s per minute, the drainage - valve closing time can be adjusted to 40 s per minute, and the drainage - valve opening degree can be adjusted to 100 degrees; the drainage - valve opening time of the floor washer can be adjusted to 30 s per minute, the drainage - valve closing time can be adjusted to 30 s per minute, and the drainage - valve opening degree can be adjusted to 180 degrees. After 2 minutes, obtain the sewage water - level status of the dishwasher again. If the sewage water - level status of the dishwasher is the sewage - water - level - rising state or the sewage - water - level - unchanged state, it indicates that the back - flow phenomenon still exists. At this time, turn off the drainage functions of the washing machine and floor washer, and adjust the washing machine and floor washer to the drainage - closed state until the dishwasher stops the drainage task.
