Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.
According to the control method of the washing device, the washing device acquires the running state information before the previous running and shutdown after the washing device is started, and whether the water drainage operation is executed or not is judged according to the running state information. Through program judgment, the washing device can automatically discharge the washing water which is remained and deteriorated inside after the washing device is started, thereby ensuring the washing effect and the health of users. The washing device provided by the invention comprises but is not limited to a pulsator washing machine, a roller washing machine, a washing and drying integrated machine and a dish washing machine.
Example one
As shown in fig. 1, the present embodiment provides a control method for a washing device, which can automatically discharge the washing water that is retained for a long time and deteriorated in quality in the washing device by program judgment after the washing device is started.
The washing apparatus detects an internal water level h, such as a washing machine, i.e., detects a water level height in a washing tub, through a water level detecting device after being turned on. The washing device compares the detected water level H with a preset water level H, and when the water level H is less than or equal to the preset water level H, the washing device is controlled to execute a set washing program. When the detected water level H is higher than the preset water level H, the washing device further judges whether to discharge the washing water inside, and then executes the set washing program.
The washing device is provided with a memory module, and before the washing device is shut down in operation, the washing device stores the current operation state information in the memory module. After the washing device is started, when the judgment of whether the drainage operation is executed needs to be carried out, the running state information before the previous running and shutdown is obtained from the memory module, and whether the drainage operation is executed is judged according to the running state information.
The running state information comprises whether water exists in the washing device during the previous running shutdown, if the water exists in the washing device, the washing device is controlled to execute the drainage operation, the set washing program is executed, and if the water does not exist in the washing device, the washing device is controlled to execute the set washing program.
Specifically, the washing device judges whether water exists in the washing device or not through the running process of the washing device before shutdown. A complete washing program includes a plurality of different stages, which may be divided into a stage with water inside and a stage without water inside, such as a washing machine, the stage with water inside includes a water inlet process, a washing process, a rinsing process and a water discharge process, and the stage without water inside includes a water discharge process just finished, a dehydration process and a dehydration process finished.
The washing device judges the stage of the current running process before shutting down, and further stores whether water exists in the current washing device as running state information in a memory module. Specifically, for the washing machine, when the washing machine is in a water inlet, washing, rinsing or draining process before shutdown, water in the washing machine during shutdown is stored in the memory module; when the washing machine is in dehydration before shutdown, or the drainage process or the dehydration process is just finished, the water in the washing machine is not needed when the washing machine is shut down and is stored in the memory module.
Or, the washing device may directly store the current running process in the memory module before shutdown, obtain the stored running process information after restarting, and determine whether water is in the washing device when shutdown.
In another scheme of this embodiment, the washing apparatus may be further controlled to detect the internal water level before the apparatus is powered off, and further, information about whether water is present in the washing apparatus during the power off is stored in the memory module.
In the embodiment, when water is detected in the washing device after the washing device is started, the running state information before the previous running and shutdown is further acquired to judge whether water is in the washing device when the washing device is shut down before the previous running and shutdown, so that whether the detected washing water is left in the washing device after the previous shutdown is judged, the detected washing water is distinguished from the situation that the user manually adds the pre-washing water before the washing device is started, and the situation that the pre-washing water manually added by the user is discharged to cause waste due to misjudgment is avoided.
In a preferred embodiment of this embodiment, the operation state information further includes an interval Δ T elapsed between the previous operation shutdown of the washing apparatus and the current startup, and when the washing apparatus determines that there is water in the washing apparatus during the previous operation shutdown, it is further determined whether the interval Δ T is greater than a preset time T. If the judgment result is yes, the washing device is controlled to execute the drainage operation and then execute the set washing program, and if the judgment result is no, the washing device is controlled to execute the set washing program.
Specifically, the washing device will be shut down for a time T before being shut down0Storing in memory module, obtaining previous shutdown time T when water is in washing device during previous operation shutdown after restarting0And the current time T1Calculating the interval time DeltaT ═ T1-T0And comparing with the preset time T to judge whether to execute the drainage operation.
In this embodiment, when the washing apparatus determines that the washing water is retained in the washing apparatus when the washing apparatus is powered off last time, the interval time Δ T between the power-off operation of the previous time and the power-on operation of this time is further calculated. When the interval time delta T is less than or equal to the preset time T, namely the washing device is restarted in a short time after being shut down, the retention time of the washing water in the washing device is relatively short, and the washing water can be used for directly cleaning the articles to be washed. When the interval time deltat is greater than the preset time T, the washing water has been retained in the washing apparatus for a long time, there is a possibility of generating bacteria or bad smell, which cannot be used for washing, and the washing apparatus is controlled to perform a draining operation to drain the washing water, which may be deteriorated.
When the washing device in the embodiment is started and water is detected in the washing device, the running state information before the previous running and shutdown can be automatically acquired, and whether the drainage operation is executed or not is judged. Only when the washing device is shut down last time, the washing device is stored with the washing water which is not discharged, and the interval time between the previous operation of the washing device and the shutdown of the washing device and the current startup is longer, the washing device firstly executes the water discharging operation and then executes the set washing program. Through above-mentioned control mode, washing device can be after the start-up automatic discharge detention time longer probably take place rotten washing water, has guaranteed that washing effect and user are healthy, directly utilizes to the washing water that the detention time is shorter, has practiced thrift the water resource, has still avoided the mistake to cause extravagant condition with the manual prewashing water discharge that adds of user simultaneously.
Example two
As shown in fig. 2 and fig. 3, the present embodiment provides a method for controlling a washing apparatus, wherein a local terminal of the washing apparatus can be connected to a server terminal in a communication manner. And sending the current running state information to a server side for storage before the washing device stops running and is shut down, detecting the water level H in the washing device after the washing device is restarted, and comparing the water level H with a preset water level H. And when the water level H is less than or equal to the preset water level H, controlling the washing device to execute a set washing program. And when the detected water level H is higher than the preset water level H, the washing device sends an instruction for inquiring the running state information to the server side, and waits for the server side to issue an instruction for judging whether to execute the drainage operation.
And the server side reads the stored running state information after receiving the instruction for inquiring the running state information, and sends an instruction for judging whether to execute the drainage operation to the local side according to the running state information.
The operation state information comprises whether water exists in the washing device during the previous operation shutdown, if the water exists in the washing device, the server side sends an instruction for executing a drainage operation to the local side, and if the water does not exist in the washing device, the server side sends an instruction for executing a set washing program to the local side.
Further, the running state information comprises a running process of the washing device before shutdown, and the server side judges whether water exists in the washing device according to the running process. For example, for a washing machine, if the washing machine is performing water inlet, washing, rinsing or drainage processes before the washing machine is turned off, the server determines that water is in the washing device when the washing machine is turned off; if the washing machine is in dehydration before the machine is shut down, or the drainage process or the dehydration process is just finished, the server judges that no water exists in the washing machine when the machine is shut down.
In a preferable scheme of this embodiment, the operation state information further includes a shutdown time T of a previous shutdown operation0When the water is in the washing device during the previous operation shutdown, the server end reads the stored shutdown time T0And obtains the current time T1Calculating the interval time DeltaT ═ T1-T0And judging whether the interval time delta T is greater than a preset time T. If the judgment result is yes, an instruction for executing the drainage operation is sent to the local terminal, and if the judgment result is no, an instruction for executing the set washing program is sent to the local terminal.
The local terminal of the washing device controls the washing device to operate according to the instruction issued by the server terminal, if the instruction for executing the drainage operation is received, the washing device is controlled to drain the internal washing water, the set washing program is executed, and if the instruction for executing the set washing program is received, the washing device is controlled to directly start to operate according to the set washing program.
In this embodiment, by providing the server capable of communicating with the home machine side of the washing apparatus, the storage of the running state information and the program judgment of whether to execute the drainage operation are both performed at the server side, and the memory at the home machine side of the washing apparatus is not occupied, so that the control program of the home machine side of the washing apparatus can be simplified. And the same server end can communicate with the local machine ends of a plurality of washing devices, so that the control of the plurality of washing devices is realized. The washing device in the embodiment is in communication connection with the server end, so that the effect of automatically discharging the washing water which is possibly deteriorated and has long retention time after the washing device is started can be achieved, and the reasonable, healthy and effective utilization of the washing water is realized.
EXAMPLE III
The present embodiment provides a method for controlling a washing apparatus, where the washing apparatus has a power-off memory function, and is capable of recording an operation process of a current washing program before the washing apparatus is powered off, and controlling a process interrupted by the previous power-off and a subsequent process of the washing apparatus when the washing apparatus is restarted and it is determined that the previous washing program is powered off and interrupted during the operation process according to the recorded operation process.
Further, the recorded running process is acquired after the washing device is restarted for judgment, when the washing program which is run last time is judged to be unfinished, whether the drainage operation is executed or not is further judged, if the judgment result is yes, water is fed after the drainage operation, and the interrupted process and the subsequent process which are run last time are executed; if the judgment result is no, directly executing the interrupted process and the subsequent process in the previous operation.
The method for determining whether to execute the drainage operation is similar to the first embodiment or the second embodiment, and the specific steps are as follows:
1) the washing device judges whether water exists in the washing device during the previous shutdown through the operation process, if the judgment result is negative, the water drainage operation is not executed, and if the judgment result is positive, the step 2) is executed;
2) the washing device obtains the previous shutdown time T0And the current time T1Calculating the interval time DeltaT ═ T1-T0Judging whether the interval time delta T is greater than the preset time T or not;
3) if the judgment result is yes, the drainage operation is executed, and if the judgment result is no, the drainage operation is not executed.
In a preferred aspect of the present embodiment, when it is determined that the drain operation is performed, the washing apparatus further determines whether a course interrupted at the previous operation is a washing course after detergent is added. If the judgment result is negative, the washing device is controlled to directly enter water to operate after the water drainage is finished, if the judgment result is positive, the washing device is controlled to enter water and add the detergent again after the water drainage is finished, and then the washing device continues to operate, or the washing device is controlled to prompt the user to add the detergent again after the water drainage is finished, and after a signal that the user finishes adding the detergent is received, the washing device is controlled to start to operate.
In the embodiment, after the washing device is restarted, whether the washing program set last time is finished is judged according to the recorded running process, and when the washing device is shut down and interrupted in the current running process, the washing device can be controlled to execute the process interrupted in the previous shutdown and the subsequent processes, so that the washing device is not required to reset the washing program, and is more convenient. The washing device judges whether to execute the drainage operation before starting to operate, can automatically discharge the washing water remained for a long time aiming at the condition that the interruption time of the washing process is longer, and then executes the unfinished part of the washing program, thereby ensuring the washing effect and the health of users. In the case where the detergent has been added but the initial washing process has not been completed, the detergent is discharged if the washing apparatus performs a draining operation. When the washing device judges that the drainage operation needs to be executed, the washing device is controlled to throw in the detergent again in the water inlet process after the drainage is finished or after the water inlet is finished, or the user is reminded to add the detergent, and the washing device starts to operate after the detergent is confirmed to be added again, so that the cleaning effect of the articles to be washed is ensured.
