Detailed Description
In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
The control method of the washing machine provided by the application is applied to the scene shown in fig. 1, and the washing machine comprises a cleaning cylinder 112, a controller (not shown), a turbidity detector 116, a flow rate detector 119 and a shell 118, wherein the cleaning cylinder 112 is arranged in the shell 118 and is used for containing laundry and washing water. The casing 118 is provided with a drain port 114, and the drain port 114 is connected to the cleaning cylinder 112 via a pipe, and the turbidity detector 116 and the flow rate detector 119 are provided at the drain port 114 and connected to the controller, respectively. During the washing process of the washing machine, the generated contaminated water can be discharged through the water discharge port 114, the turbidity detector 116 is used for collecting turbidity data of the contaminated water discharged from the water discharge port 114, and the flow rate detector 119 is used for detecting a discharge rate of the contaminated water discharged from the water discharge port 114. The controller receives the turbidity data sent by turbidity detector 116 and the drain rate sent by flow rate detector 119, and further analyzes the turbidity data in combination to determine the final turbidity parameter. Finally, the controller realizes the control of the washing machine according to the current turbidity parameter of the current washing task and the historical turbidity parameter before the current washing task is executed after the washing machine is started for the first time or the barrel cleaning task is executed last time. Further, in one embodiment, the controller may also combine turbidity parameters, historical turbidity parameters, and historical turbidity parameters to achieve washing machine control.
Referring to fig. 2, a control method of a washing machine includes steps 202, 204 and 206.
Step 202, obtaining a current turbidity parameter.
Specifically, the current turbidity parameter is a turbidity parameter of the drain outlet of the washing machine to drain the sewage when the washing machine performs the current washing task. In the actual cleaning process, the dirt degree of clothes washed in the washing machine has a direct proportion to the dirt degree of the cleaning cylinder, and the dirty clothes are, the higher the turbidity of the soaking water or the washing water is, the more serious pollution is caused to the cleaning cylinder correspondingly. Therefore, the scheme of the embodiment combines the turbidity parameters of the sewage discharged from the water outlet of the washing machine to realize the control of the washing machine.
It will be appreciated that the manner in which the turbidity parameters are obtained is not exclusive, and in one embodiment, by providing a turbidity detector at the drain, the effluent is collected using the turbidity detector and the collection is sent to a controller connected thereto (which may be a wired connection or a wireless communication connection) where the current turbidity parameters are ultimately determined.
In one embodiment, the turbidity detector can collect turbidity data corresponding to a plurality of different drainage times in the drainage process of the washing machine because the washing machine generally lasts for a certain time due to more water in the cleaning cylinder in the drainage process, and the controller can analyze and process (such as mean value processing) after obtaining each turbidity data to obtain a final current turbidity parameter, so that the accuracy of the current turbidity parameter is ensured.
Further, in other embodiments, more than two turbidity detectors may be disposed at the drain outlet, and in the draining process, each turbidity detector respectively collects one turbidity data and sends the turbidity data to the controller, and the controller performs analysis processing (may be mean processing or the like) by combining the turbidity data collected by each turbidity detector, so as to finally obtain the current turbidity parameter, thereby ensuring the accuracy of the current turbidity parameter.
It should be noted that in another embodiment, a turbidity detector may be provided, and turbidity data is collected by the turbidity detector once during the draining process of the washing machine, so as to be used as a current turbidity parameter, thereby improving the detection efficiency of the current turbidity parameter.
Step 204, determining whether the washing machine meets the drum cleaning condition according to the current turbidity parameter and the historical turbidity parameter.
Specifically, the historical turbidity parameter is the turbidity parameter of the sewage discharged from the water outlet under each cleaning task after the washing machine is started for the first time or after the previous time of executing the cylinder cleaning task and before the current time of executing the cleaning task.
The cylinder cleaning condition is the condition which is required to be met for cleaning the cleaning cylinder of the washing machine. If the washing machine has not previously performed a drum cleaning task, in the actual analysis process, the turbidity parameters acquired by the controller are analyzed to detect whether the current washing machine meets the drum cleaning condition or not when the washing task is performed for the past time within the period from the time of starting the washing machine for the first time to the time of performing the washing task before the current washing task.
If the washing machine has previously performed the drum cleaning task, the controller will re-count the turbidity parameters after performing the drum cleaning task, and analyze the turbidity parameters obtained by the controller and the current turbidity parameters to detect whether the current washing machine meets the drum cleaning condition when the washing task is performed for the past time between the time when the outer drum cleaning task is performed and the time when the current washing task is performed.
Step 206, pushing the drum cleaning reminding information if the washing machine meets the drum cleaning condition.
Specifically, after detecting that the washing machine meets the drum cleaning condition, the controller generates drum cleaning reminding information and pushes the drum cleaning reminding information to a user, so that the user can know the drum cleaning reminding information in time, and the user can start the drum cleaning task of the washing machine when the washing machine is idle.
It will be appreciated that in one embodiment, the drum cleaning task of the washing machine may also be automatically turned on, and after the controller determines that the drum cleaning condition is met in combination with the current turbidity parameter and the historical turbidity parameter, in addition to pushing the drum cleaning reminder to the user, the drum cleaning operation may be started when it is detected that the washing machine has completed the current cleaning task and is in an idle state.
It should be noted that the pushing manner of the drum cleaning reminding information is not unique, in one embodiment, an information reminding device may be provided in the washing machine, and the controller may push the drum cleaning reminding information to the information reminding device, and then the information reminding device outputs a reminding signal to inform the user.
While the particular type of information-prompting device is not exclusive, in a more detailed embodiment, the information-prompting device may be any one of a display screen, an audible alarm, or a light alarm. The type of information presentation device is not particularly limited.
Further, in one embodiment, the cartridge cleaning reminder information may also be pushed to the user terminal to inform the user. According to the scheme of the embodiment, the controller is in communication connection with the user terminal (can be a mobile phone or a wearable device) and pushes the barrel cleaning reminding information to the user terminal when the fact that the washing machine meets the barrel cleaning condition is detected, and a user can check the barrel cleaning reminding information through the user terminal.
According to the control method of the washing machine, when the washing machine is started to execute the current cleaning task, the current turbidity parameters of the sewage discharged by the water outlet of the current washing machine are obtained, and the historical turbidity parameters of the sewage discharged by the water outlet under each cleaning task are combined after the washing machine is started for the first time or after the previous time to execute the barrel cleaning task, so that whether the washing machine meets the barrel cleaning condition is analyzed. When the washing machine meets the drum cleaning condition, the drum cleaning reminding information is pushed so that a user can clean the drum even though the washing machine is cleaned. According to the scheme, the barrel cleaning of the washing machine is associated with the turbidity of the sewage discharged from the water outlet, whether the washing machine meets the barrel cleaning condition is automatically analyzed, and the barrel cleaning reminding information is pushed to remind a user when the barrel cleaning condition is met, so that the user does not need to independently judge whether to start the barrel cleaning, and the problem that the barrel cleaning is easy to frequently start or serious dirt is not yet started is solved.
In one embodiment, the turbidity parameters of the drain outlet to drain the waste water are: and after the soaking stage is finished, the water outlet discharges turbidity parameters of the soaked sewage.
Specifically, washing of laundry is generally classified into a soaking stage, a washing stage, a rinsing stage, a dehydrating stage, and the like. The soaking stage refers to a time period of soaking clothes in a washing task when the washing machine executes the washing task; the soaked sewage is the sewage discharged after the clothes in the cleaning cylinder are soaked. According to the scheme of the embodiment, the controller is used for analyzing the corresponding turbidity parameters according to the turbidity data obtained by collecting the soaking sewage discharged from the water outlet after the soaking stage of the turbidity detector is completed. Namely, under the current cleaning task and the historical cleaning task, the controller analyzes the turbidity data according to the turbidity data of the soaked sewage to obtain turbidity parameters, and performs corresponding control operation according to the turbidity parameters of the soaked sewage in each cleaning task.
According to the scheme of the embodiment, when each cleaning task is executed, the corresponding turbidity parameter is obtained according to the analysis of the soaking sewage discharged in the soaking stage, so that the turbidity parameter can more accurately represent the dirt degree of the cleaning cylinder, and the detection reliability of cylinder cleaning is improved.
It will be appreciated that in other embodiments, the turbidity parameters of the drain outlet effluent may also be as follows, since some cleaning tasks do not have a soaking stage (e.g. a cleaning task corresponding to a wool or silk garment): after the washing stage is completed, the water outlet discharges turbidity parameters of the washing sewage. The washing stage is a period of time for decontaminating and washing clothes; the washing sewage is the sewage discharged after the clothes are decontaminated and washed. According to the scheme of the embodiment, after the washing stage is finished, the turbidity parameters of the discharged washing sewage are obtained, and the detection operation of cylinder cleaning can be realized.
Referring to FIG. 3, in one embodiment, step 204 includes steps 302 and 304.
Step 302, determining a turbidity average according to the current turbidity parameter and the historical turbidity parameter.
Step 304, determining whether the washing machine meets the drum cleaning condition according to the turbidity average value.
Specifically, according to the scheme of the embodiment, after obtaining the current turbidity parameter corresponding to the current cleaning task and the obtained historical turbidity parameter in the historical cleaning task of the current cylinder cleaning period, the controller carries out average value solving on each turbidity parameter to obtain a turbidity average value, and finally analyzes whether the washing machine meets the cylinder cleaning condition according to the turbidity average value.
It will be appreciated that in one embodiment, if the canister cleaning condition is met and the canister cleaning operation is completed, the controller clears the historical turbidity parameter of the canister cleaning detection program and re-opens the next canister cleaning cycle. And when the controller does not meet the cleaning conditions of the cylinder according to the analysis of the current turbidity parameters and the historical turbidity parameters, updating and storing the current turbidity parameters in the historical turbidity parameters, and continuously executing the next cleaning task according to the requirements of the user. And when the cleaning task is executed each time, the controller acquires the current turbidity parameter and solves the current turbidity parameter and the historical turbidity parameter to obtain a turbidity average value, and whether the cleaning condition of the cylinder is met is analyzed according to the turbidity average value.
Referring to FIG. 4, in one embodiment, step 304 includes steps 402 and 404.
Step 402, determining a current pollution degree coefficient according to the turbidity average value and a preset corresponding relation between the turbidity average value and the pollution degree coefficient.
Step 404, determining whether the washing machine satisfies a drum cleaning condition according to the current dirt level coefficient.
Specifically, in the solution of this embodiment, the dirt level coefficient is used to characterize the dirt level of the cleaning drum of the washing machine. The corresponding relation between the turbidity average value and the dirt degree coefficient is prestored in the controller, after the turbidity average value is obtained by combining the analysis of the current turbidity parameter and the historical turbidity parameter by the controller, the turbidity average value is brought into the corresponding relation between the preset turbidity average value and the dirt degree coefficient for matching, and the current dirt degree coefficient can be obtained. Finally, the controller further determines whether the washing machine satisfies a drum cleaning condition based on the current soil level coefficient.
The corresponding relation between the preset turbidity average value and the dirt degree coefficient is not unique, and in a more detailed embodiment, the corresponding relation may be obtained by testing the same type of washing machine in an experimental environment and stored in a controller of the washing machine.
It should be noted that the correspondence between the turbidity average value and the fouling degree coefficient is not unique in the storage manner in the controller, and in one embodiment, the storage may be performed by a form of a graph, a table, or the like, which is not particularly limited.
In one embodiment, different fouling coefficients can be set for different turbidity average value ranges, the turbidity average values in the same turbidity average value range have the same corresponding fouling coefficients, and the turbidity average values in different turbidity average value ranges have different corresponding fouling coefficients. In a more detailed embodiment, four soil level coefficients are illustrated, as shown in the following table:

Figure BDA0004035677340000114
Within that, the corresponding current dirt degree coefficient is D 4 。
It will be appreciated that in other embodiments, there may be a soil level coefficient for each turbidity average, the greater the turbidity average, the higher the soil level coefficient. The correspondence between the turbidity average value and the dirt degree coefficient is not unique, and is not limited in this case, and what kind of correspondence is specifically adopted is only required to be set in combination with actual demands.
Referring to fig. 5, in one embodiment, step 404 includes step 502.
Step 502, determining that the washing machine meets the drum cleaning condition if the current dirt level coefficient is greater than or equal to a preset coefficient threshold.
Specifically, a preset coefficient threshold value is pre-stored in the controller, after the controller analyzes the current dirt degree coefficient, the current dirt degree coefficient is compared with the preset coefficient, and when the current dirt degree coefficient is greater than or equal to the preset coefficient threshold value, the washing machine is considered to meet the cleaning condition of the drum.
According to the scheme, after the fact that the current dirt degree coefficient is larger than or equal to the preset coefficient threshold is detected, the fact that the washing machine meets the cylinder cleaning condition is directly determined, so that cylinder cleaning reminding information is pushed, and the method has the advantage of being high in detection speed.
It should be noted that the magnitude of the preset coefficient threshold is not unique, and the preset coefficient threshold may be different according to the correspondence between the turbidity average value and the fouling degree coefficient. In a more detailed embodiment, the soil level coefficient includes D 1 、D 2 、D 3 、D 4 At this time, the preset coefficient threshold may be set to D 3 。
In another embodiment, if the current soil level coefficient is less than the preset coefficient threshold, it is determined that the washing machine does not meet the drum cleaning condition, and the current turbidity parameter is recorded at this time, and the washing task is continuously executed according to the user requirement.
Referring to FIG. 6, in one embodiment, step 404 includes steps 602 and 604.
Step 602, if the current dirt degree coefficient is greater than or equal to a preset coefficient threshold, obtaining a drainage rate of last drainage when the washing machine executes the current cleaning task.
Step 604, determining whether the washing machine satisfies a drum cleaning condition according to the current soil level coefficient and the drain rate.
Specifically, when the washing machine performs a washing task, after entering a draining stage, the washing machine drain will filter some filigree, knitting wool, fine sand, etc., which are also components of the contaminants in the washing machine tank. The small volume of the filter can flow out along the drain pipe, but the large volume of the filter can be filtered and stays on the filter screen, and when the pollutants accumulate to a certain degree, the drainage of the washing machine is affected. That is, the drain of the washing machine can reflect the dirt degree of the cleaning cylinder of the washing machine to a certain extent.
Therefore, in the solution of this embodiment, when it is detected that the current dirt level coefficient is greater than or equal to the preset coefficient threshold, the controller further needs to obtain the drain rate of the last drain when the washing machine performs the current washing task. Finally, the detection operation of whether the cleaning of the cylinder is satisfied is realized by combining the drainage rate and the current dirt degree coefficient. According to the scheme, when the current dirt degree coefficient is detected to be larger than or equal to the preset coefficient threshold, whether the cylinder cleaning condition is met or not is detected by combining the current dirt degree coefficient and the drainage rate, and the detection accuracy of cylinder cleaning is improved.
It will be appreciated that the manner in which the drain rate is obtained is not the only way in which the drain port of the washing machine is provided, in one embodiment, with a flow rate detector by which the flow rate of water is obtained as the washing machine drains. Further, the flow rate corresponding to the last water discharge operation of the cleaning task is only required to be used as the water discharge rate.

Accordingly, in the case that the tub cleaning desired value is greater than or equal to the preset desired threshold value, the washing machine is considered to satisfy the tub cleaning condition.
It should be noted that the manner of obtaining the preset desired threshold is not exclusive, and in one embodiment, may be obtained by performing experimental analysis on the same type of washing machine in an experimental environment, and stored in the controller.
Referring to fig. 10 in combination, in order to facilitate understanding of the technical solution of the present application, the following description will explain the present application in connection with more detailed embodiments.
After the washing machine has performed a drum cleaning task, the turbidity parameters associated with the controller drum cleaning program will be cleared and the controller will re-record the turbidity. After the cylinder cleaning task is executed last time and before the current cleaning task, the controller analyzes the obtained historical turbidity parameters according to turbidity data obtained by collecting the soaking sewage after the soaking stage is completed by the turbidity detector in each cleaning task. And analyzing the turbidity data acquired by collecting the soaked sewage after the soaking stage of the current cleaning task is completed to acquire the current turbidity parameters.
And then the controller carries out mean value solving on the historical turbidity parameters and the current turbidity parameters to obtain a turbidity average value, and the turbidity average value is brought into a corresponding relation between the preset turbidity average value and the pollution degree coefficient to be matched to obtain the current pollution degree coefficient. In particular according to the mean value of turbidity

The specific position in the constructed interval is obtained by matching. If the current dirt degree coefficient is D 1 Or D 2 And the cleaning condition of the cylinder is not met at the moment, and the cleaning task is continuously executed according to the requirement of the user. If the current dirt degree coefficient is D 3 Or D 4 Indicating that the cleaning cylinder has dirty to a certain extent, at this time, the controller will acquire the drainage rate of the last drainage when the washing machine performs the current cleaning task, and substituting the current dirty degree coefficient and the drainage rate into e=dx1/V, and calculating to obtain the cylinder cleaning expected value.
Finally, the controller analyzes whether the cylinder cleaning expected value is greater than or equal to a preset expected threshold, and if the cylinder cleaning expected value is greater than or equal to the preset expected threshold, the controller indicates that the cylinder cleaning condition is met, and then the cylinder cleaning reminding information is pushed. If the cylinder cleaning expected value is smaller than the preset expected threshold value, the cleaning task is continuously executed according to the user requirement.
