[0028] Figure 1 A flow chart of a control method for a laundry appliance provided in an embodiment of the present invention is provided. The method may be executed by a control device for the laundry appliance. The control device for the laundry appliance may be implemented in the form of hardware and / or software. The control device for the laundry appliance may be configured in the laundry appliance, such as Figure 2 As shown, the laundry machine 2 can include a filter screen 20 and a diaphragm pump 21, and the diaphragm pump 21 is used to spray a dissolving agent to dissolve the particles on the filter screen 20. Figure 1 As shown, the method may specifically include the following steps:

[0029] S101, obtaining the actual drainage time and the actual water level of the laundry machine, and determining the standard drainage time corresponding to the actual water level.

[0030] The actual drainage time may be understood as the actual time taken by the laundry machine to drain water; and the standard drainage time may be understood as the drainage time corresponding to the preset actual water level.

[0031] In an optional implementation, the water consumption is determined according to the actual water level, and the preset information is queried according to the water consumption to obtain the standard drainage time corresponding to the water consumption. The preset information may include the standard drainage time corresponding to each water consumption.

[0032] S102: When the actual drainage time exceeds the standard drainage time, a drainage time difference is determined according to the actual drainage time and the standard drainage time.

[0033] Among them, the drainage time difference can be understood as the difference between the actual drainage time and the standard drainage time.

[0034] In actual applications, if the filter is clogged, the water flow rate through the filter may decrease when the laundry machine runs the drainage program, and the actual drainage time of the laundry machine may exceed the standard drainage time corresponding to the actual water level; the more serious the degree of blockage of the filter, the greater the difference in drainage time between the actual drainage time and the standard drainage time. Therefore, in an optional embodiment, if the actual drainage time exceeds the standard drainage time, it can be determined that the filter is clogged, and then the difference between the actual drainage time and the standard drainage time can be calculated to obtain the drainage time difference, and whether to control the diaphragm pump to spray the solvent to the filter is determined according to the drainage difference.

[0035] S103, when the drainage time difference belongs to the preset spraying difference interval, control the diaphragm pump to spray the solvent onto the filter.

[0036] Among them, the preset spray difference interval can be understood as a preset drainage time difference interval required to control the diaphragm pump to spray the solvent onto the filter.

[0037] In an optional embodiment, the degree of blockage of the filter is determined according to the drainage time difference and the preset spray difference interval, the spray parameters are determined according to the blockage degree, and the diaphragm pump is controlled to spray the solvent onto the filter according to the spray parameters. Wherein, the preset spray difference interval includes a first spray difference interval and a second spray difference interval, and the drainage time difference in the first spray difference interval is smaller than the drainage time difference in the second spray difference interval; the blockage degree may include mild blockage and moderate blockage, the spray parameters may include the spray time of the diaphragm pump spraying the solvent onto the filter, and the spray amount of the diaphragm pump spraying the solvent onto the filter, the spray time may include a first spray time and a second spray time, the first spray time is smaller than the second spray time, the spray amount may include a first spray amount and a second spray amount, and the first spray amount is smaller than the second spray amount.

[0038] Specifically, different degrees of blockage correspond to different spray parameters. The more severe the blockage, the longer the spray time and the greater the spray volume. Therefore, when the drainage time difference belongs to the first spray difference interval, the blockage degree is determined to be mild blockage. When the blockage degree is mild blockage, the spray parameters are determined to be the first spray time and the first spray volume; when the drainage time difference belongs to the second spray difference interval, the blockage degree is determined to be moderate blockage. When the blockage degree is moderate blockage, the spray parameters are determined to be the second spray time and the second spray volume.

[0039] For example, the drainage time difference is S, the first spray time is T1, the first spray amount is C1, the second spray time is T2, the second spray amount is C2, T1<T2, C1<C2, the first spray difference interval is [S1, S2) , and the second spray difference interval is [S2, S3) ; if S1<S<S2, it can be determined that the drainage time difference belongs to the first spray difference interval, and the blockage degree can be determined to be mild blockage. When the blockage degree is mild blockage, the spray parameters are determined to be the first spray time T1 and the first spray amount C1; if S2<S<S3, it can be determined that the drainage time difference belongs to the second spray difference interval, and the blockage degree is determined to be moderate blockage. When the blockage degree is moderate blockage, the spray parameters are determined to be the second spray time T2 and the second spray amount C2.

[0040] In this embodiment, the actual drainage time and the actual water level of the laundry machine are obtained, and the standard drainage time corresponding to the actual water level is determined; when the actual drainage time exceeds the standard drainage time, it means that the water flow rate when the water passes through the filter is less than the normal water flow rate when the filter is not blocked, and it can be determined that the filter is blocked, and the drainage time difference is determined according to the actual drainage time and the standard drainage time; when the drainage time difference belongs to the preset spray difference interval, the diaphragm pump is controlled to spray the solvent to the filter to dissolve the particles on the filter, reduce the blockage degree of the filter, and reduce the drainage time required for the laundry machine to run the drainage program next time, thereby reducing the use cost of the laundry machine, increasing the intelligence of the laundry machine, providing users with a better use experience of the laundry machine, and solving the problem of long drainage time of the laundry machine and increased use cost of the laundry machine due to serious blockage of the filter.

[0041] Figure 3 Another flow chart of the control method of the laundry device provided by the embodiment of the present invention is as follows: Figure 3 As shown, the method may include the following steps:

[0042] S301, determining water consumption according to the actual water level.

[0043] S302, querying preset information according to the water consumption to obtain a standard drainage time corresponding to the water consumption.

[0044] The preset information may include the standard drainage time corresponding to each water consumption.

[0045] In an optional embodiment, the standard drainage time corresponding to each water consumption can be stored in preset information in advance, so that during the control process of the laundry equipment, the preset information can be directly queried according to the water consumption to obtain the standard drainage time corresponding to the water consumption, thereby improving the control efficiency of the laundry equipment.

[0046] S303, determine whether the actual drainage time exceeds the standard drainage time. When the actual drainage time does not exceed the standard drainage time, execute S304; when the actual drainage time exceeds the standard drainage time, execute S305.

[0047] S304, determining that the filter is not clogged.

[0048] In an optional embodiment, if the filter is not blocked, when the laundry machine runs the drainage program, the drainage flow rate when the water passes through the filter is a normal drainage flow rate, and thus the actual drainage time of the laundry machine will not exceed the standard drainage time corresponding to the actual water level. Therefore, if the actual drainage time does not exceed the standard drainage time, it can be determined that the filter is not blocked.

[0049] S305: Determine the drainage time difference according to the actual drainage time and the standard drainage time.

[0050] S306, determine whether the drainage time difference belongs to the preset spray difference interval. When the drainage time difference does not belong to the preset spray difference interval, execute S307; when the drainage time difference belongs to the preset spray difference interval, execute S309.

[0051] S307, determine whether the drainage time difference belongs to the preset alarm difference interval. When the drainage time difference does not belong to the preset alarm difference interval, return to execute S301; when the drainage time difference belongs to the preset alarm difference interval, execute S308.

[0052] Among them, the preset alarm difference interval can be understood as the preset drainage time difference interval for the filter blockage alarm prompt. The drainage time differences in the preset alarm difference interval are all greater than the drainage time in the preset spray difference interval. The blockage degree of the filter may also include severe blockage; when the drainage time difference belongs to the preset alarm difference interval, it means that the blockage degree of the filter is severe. At this time, the diaphragm pump is controlled to spray the solvent to the filter, but the particles accumulated on the filter cannot be dissolved, and the filter blockage alarm prompt is required to enable the user to manually clean the filter in time according to the filter blockage alarm prompt, so as to solve the problem that the filter is not cleaned in time, and the next time the user uses the laundry machine, the laundry machine will have a long drainage time due to severe blockage of the filter, and the use cost of the laundry machine will be increased.

[0053] S308, issuing a filter blockage alarm.

[0054] In an optional implementation, a filter clogging alarm may be generated and sent to a user terminal device bound to the laundry device to prompt the user to clean the filter in time.

[0055] S309, determining the clogging degree of the filter screen according to the drainage time difference and the preset spray difference interval.

[0056] S310, determining spray parameters according to the degree of blockage.

[0057] S311, controlling the diaphragm pump to spray the solvent onto the filter screen according to the spraying parameters.

[0058] Among them, Figure 2 As shown, the laundry device 2 may further include a solvent delivery box 22, such as Figure 4As shown, the diaphragm pump includes a motor 211, a diaphragm 212, a solvent outlet 213, a solvent inlet 214 connected to the solvent delivery box 22, and a cam 215. In actual use, the motor 211 rotates to drive the cam 215 to move half a circle, so that the diaphragm 212 moves toward the motor 211, and the diaphragm chamber is at negative pressure, and the solvent can be sucked from the solvent inlet 214. When the motor 211 rotates and drives the cam 215 to continue to move half a circle, the diaphragm 212 moves in the opposite direction of the motor 211, the diaphragm chamber is at positive pressure, and the solvent is sprayed from the solvent outlet 213 to the filter.

[0059] In an optional embodiment, the number of revolutions of the motor corresponding to the spraying duration is determined; and the number of revolutions of the motor is controlled to spray a spraying amount of solvent onto the filter.

[0060] Specifically, the single rotation duration of the diaphragm pump's motor for one rotation is fixed, and the number of rotations of the motor can be determined based on the spraying duration and the single rotation duration.

[0061] For example, if the spraying time is T3, the single rotation time of the motor is t, and the number of rotations of the motor is determined to be T3 / t=2 according to the spraying time and the single rotation time, and the motor is controlled to rotate 2 circles to spray the spraying amount of solvent onto the filter.

[0062] S312, after a preset time, the current weight of the filter is detected by a weight sensor.

[0063] S313, determining whether the current weight exceeds the preset weight, if the current weight exceeds the preset weight, returning to execute S304; if the current weight does not exceed the preset weight, returning to execute S301.

[0064] The preset weight may be understood as a critical value of the preset filter weight.

[0065] In an optional embodiment, when the current weight is greater than the preset weight, it is determined that the current weight exceeds the preset weight, indicating that after the diaphragm pump is controlled to spray the solvent onto the filter according to the spray parameters, the particulate matter accumulated on the filter is not completely dissolved by the solvent, and the filter needs to be manually cleaned. Therefore, a filter blockage alarm prompt is required to enable the user to clean the filter in time according to the filter blockage alarm prompt; when it is determined that the current weight does not exceed the preset weight, it means that after the diaphragm pump is controlled to spray the solvent onto the filter according to the spray parameters, the blockage degree of the filter is reduced, and the filter does not need to be manually cleaned, which can trigger the operation of determining the water consumption according to the actual water level.

[0066] In this embodiment, the actual drainage time and the actual water level of the laundry machine are obtained, and the standard drainage time corresponding to the actual water level is determined; when the actual drainage time exceeds the standard drainage time, it means that the water flow rate when the water passes through the filter is less than the normal water flow rate when the filter is not blocked, and it can be determined that the filter is blocked, and the drainage time difference is determined according to the actual drainage time and the standard drainage time; when the drainage time difference belongs to the preset spray difference interval, the diaphragm pump is controlled to spray the solvent to the filter to dissolve the particles on the filter, reduce the blockage degree of the filter, and reduce the drainage time required for the laundry machine to run the drainage program next time, thereby reducing the use cost of the laundry machine, increasing the intelligence of the laundry machine, providing users with a better use experience of the laundry machine, and solving the problem of long drainage time of the laundry machine and increased use cost of the laundry machine due to serious blockage of the filter.
