The drawings are merely schematic illustrations of the present application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.
The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the present specification.
The working process of the full-automatic washing machine comprises the following steps: the method comprises the steps of water injection, washing, water drainage, dehydration and the like, wherein the steps are automatically and sequentially executed until the washing is finished and the end of the washing is prompted. The blockage detection method of the washing machine drainage filtering device is embedded into the working process of the washing machine to be implemented.
Fig. 1 is a flowchart of a clogging detection method of a drain filtering apparatus of a washing machine according to an embodiment of the present application.
The washing tub of the washing machine has a first water level line and a second water level line, and the first water level line is higher than the second water level line. The washing tub includes an inner tub rotatably disposed in an outer tub, and a drain pipe having one end communicated with the outer tub and the other end communicated with an external environment of the washing machine, such as a drain floor drain, and a drain filtering device may be disposed in the drain pipe to filter washing water discharged from the washing tub.
As shown in fig. 1, in this embodiment, the method for detecting clogging of the drain filter of the washing machine may specifically include the following steps S110 to S150.
Step S110, the weight of the articles to be washed in the washing barrel is obtained, and the drainage time threshold is determined according to the weight of the articles to be washed.
Before water is filled, the weight of the to-be-washed clothes can be obtained according to the weight difference detected by the gravity sensors arranged in the washing barrel before and after the to-be-washed clothes are put in, and the weight of the to-be-washed clothes can also be obtained in other modes, for example, the weight of the clothes is input by a user, or the weight is obtained by other electronic weighing equipment and is transmitted to a controller of the washing machine.
It should be noted that, when the weight of the laundry is large, the amount of the laundry is increased in the space of the washing tub defined by the first water level line and the second water level line. Since the amount of water absorbed into the laundry is generally large, the water level is lowered from the first water level line to the second water level line at a low speed when the weight of the laundry is large.
Therefore, the drainage time threshold can be determined according to the weight of the laundry, so that the set drainage time threshold is matched with the weight of the laundry, and the set drainage time threshold is more accurate. Wherein, the drainage time threshold is a reference value for judging whether the drainage filtering device is blocked. Illustratively, a determination of poor drain drainage may be made when the drain time is greater than a drain time threshold.
And after the weight of the to-be-washed objects in the washing barrel is obtained, water is injected for washing.
And step S120, after washing is finished, detecting the water level in the washing barrel.
Specifically, a plurality of water level sensors may be disposed in the washing tub to obtain a current water level in the washing tub and a positional relationship between the current water level and the first and second water level lines through the water level sensors.
In step S130, in case that the water level in the washing tub is higher than the first water level line, the water discharge is started.
After the position relations between the current water level and the first water level line and between the current water level and the second water level line are obtained through the detection result of the water level sensor, different processing modes can be adopted according to different position relations between the current water level and the first water level line and between the current water level and the second water level line. Specifically, in case that the water level in the washing tub is higher than the first water level line, the water discharge is started to detect the clogging condition during the water discharge. And under the condition that the water level in the washing barrel is lower than the first water level line, starting water injection until the water level exceeds the first water level line, so that the initial drainage water level for detecting blockage every time is consistent.
In some embodiments, the washing tub further has a third water level therein, the third water level being higher than the first water level. The clogging detecting method of the drain filtering apparatus may further include the steps of, after detecting the water level in the washing tub:
filling water or draining water into the washing tub to make the water level in the washing tub reach the third water level line;
the drain of the washing tub is controlled to obtain a drain time from the first water level line to the second water level line during the drain.
In particular, since the water level sensor has a physical volume, it is possible that the water level may not be precisely positioned at the position of the first water level line by the general water level sensor. Therefore, a third water level line can be arranged above the first water level line, and water is drained from the third water level line to ensure that the water level during draining is higher than the first water level line. And, in the process of draining, the water level sensor can conveniently and accurately acquire the draining time when the water level drops from the first water level line to the second water level line. The water level sensor may be a switch type sensor such that a switch signal of the water level sensor is changed to transmit the water level when the water level reaches a position range sensed by the water level sensor.
In the step S140, in the draining process, the draining time for the water level to drop from the first water level line to the second water level line is obtained.
And controlling the drainage pump to drain when the water level in the washing barrel is determined to be higher than the first water level line, and recording the drainage time of the water level from the first water level line to the second water level line in the drainage process. Illustratively, the time when the water level reaches the first water level line can be recorded, and the time when the water level falls from the first water level line to the second water level line can be easily calculated. Or the time counting can be started when the water level reaches the first water level line, and the time counting is stopped when the water level reaches the second water level line, so as to obtain the drainage time.
And step S150, determining the blockage condition of the drainage filtering device according to the comparison result of the drainage time and the drainage time threshold value.
As described above, the drain time threshold is a reference value for determining whether the drain filter is clogged. Illustratively, a determination of poor drain drainage may be made when the drain time is greater than a drain time threshold. In one embodiment, in order to make the judgment of the blockage situation more accurate, a multi-time detection mode can be adopted, and when the blockage detection results are all blocked continuously for multiple times, a prompt that the drainage filtering device needs to be cleaned can be sent.
The prompt may be perceived by the user in one or more of visual, audible, etc., e.g., the user may be prompted to clear the drain filter device by display and beep.
Therefore, the drainage time threshold is determined by the weight of the objects to be washed in the washing barrel, so that the drainage time threshold is related to factors such as the size of a space defined by the first water level line and the second water level line, the drainage diameter of the drainage pipe and the like, and is also related to the weight of the objects to be washed, and the drainage time threshold can be set more accurately. Furthermore, the blockage of the drainage filtering device is determined according to the drainage time and the drainage time threshold value when the water level drops from the first water level line to the second water level line, so that the blockage of the drainage filtering device can be conveniently and accurately detected. More importantly, the blockage detection method of the washing machine drainage filtering device can be embedded into the working process of the washing machine, hardware setting does not need to be changed, and only software support is needed, so that the scheme described in the application is relatively easy to implement.
In some embodiments, the method for detecting clogging of a drain filter device of a washing machine after acquiring the weight of the laundry may further include:
determining a load weight interval of the washing machine according to the weight of the articles to be washed, wherein the load weight interval is a ratio interval of the weight of the articles to be washed in the total weight capable of being washed;
and determining a drainage time threshold according to the load weight interval.
Specifically, the total washable weight is a total weight that can be washed in a single washing operation set in the washing machine, for example, 10 KG. If the weight of the object to be washed is 5KG, the ratio of the weight of the object to be washed to the total weight of the object to be washed is 0.5. The ratio of 0.4 to 0.6 can be determined as the same load weight interval, and the drainage time threshold is determined according to the load weight interval. This reduces the increase in control complexity due to the difference in the weight of the laundry.
In some embodiments, determining the drainage time threshold from the load weight interval comprises: and determining the drainage time threshold corresponding to the load weight interval according to the corresponding relation between the load weight interval and the drainage time threshold. Illustratively, if the ratio is 1, the drainage time threshold corresponding to the weight of the laundry and the total weight of the laundry may be obtained according to a plurality of tests or calculations, and the load weight interval and the drainage time threshold corresponding to the load weight interval are stored correspondingly, so as to conveniently determine the drainage time threshold corresponding to each load weight interval.
Fig. 2 is a flowchart of a clogging detecting method of a drain filtering apparatus of a washing machine according to another embodiment of the present application. As shown in fig. 2, in this embodiment, after determining the clogging condition of the drainage filtering device according to the comparison result between the drainage time and the drainage time threshold, the method may specifically include the following steps:
step S210, obtaining the saved historical overtime times, wherein the historical overtime times are the times that the drainage time before the current time point is greater than the drainage time threshold;
step S220, when the drainage time is greater than the drainage time threshold, updating the historical overtime times;
and step S230, when the historical overtime frequency exceeds the preset frequency, sending a blockage prompt of the drainage filtering device.
Specifically, as the number of washing times increases, debris such as debris in the laundry is gradually accumulated. It is known that the process of stacking is a slow process. The historical overtime times are the times that the drainage time before the current time point is greater than the drainage time threshold value. And when the drainage time in the continuous and multiple detection processes is greater than the drainage time threshold value, the drainage is determined to be unsmooth. Therefore, on one hand, the washing machine can prevent the user from being questioned about the performance of the washing machine due to the fact that the user is frequently reminded of cleaning, on the other hand, whether the washing machine is blocked or not can be detected more accurately, and the situation that the washing machine is mistakenly reminded due to misdetection caused by accidental factors is prevented from occurring.
In some embodiments, the method for detecting clogging of a drain filter device of a washing machine after acquiring the weight of laundry in a washing tub may further include the steps of:
obtaining the type of the object to be washed;
the draining time threshold is determined according to the type and weight of the laundry.
Specifically, the drainage time threshold may be determined in accordance with the weight of the laundry and the type of the laundry. Types of the laundry include summer clothes and winter clothes. As can be easily understood, the summer clothing is generally thin, and the water absorbed by the thin clothing is generally less than that absorbed by the heavy clothing, therefore, in the same drainage process, the drainage time threshold corresponding to the summer clothing of the laundry can be set to be lower than the drainage time threshold corresponding to the winter clothing of the laundry, so that the drainage time threshold can be set more accurately.
In another embodiment, the type of laundry may be further differentiated according to the fabric of the laundry, which may be known by the washing mode selected by the user, for example, if the user selects real silk washing, the drainage time threshold may be accurately set according to the water absorbency of the real silk and the weight of the washed real silk.
For a better understanding, the method for detecting clogging of a drain filter of a washing machine provided by the present application will be described below with reference to a specific embodiment.
Fig. 3 is a flowchart of a clogging detecting method of a drain filtering apparatus of a washing machine according to still another embodiment of the present application. As shown in fig. 3, the method for detecting clogging of a drain filter of a washing machine may specifically include the following steps.
Step S301, running a weighing program to obtain the weight of the object to be washed in the washing barrel;
step S302, determining a drainage time threshold according to the weight of the to-be-washed object;
step S303, detecting the water level in the washing tub;
step S304, judging whether the water level reaches a third water level line; if yes, go to step S305, otherwise go to step S306;
step S305, controlling drainage;
step S306, injecting water;
step S307, in the drainage process, the drainage time of the first water level line descending to the second water level line is obtained;
step S308, judging whether the drainage time is greater than a drainage time threshold value; if not, go to step S314; if yes, go to step S309;
step S309, acquiring historical overtime times;
step S310, updating the historical overtime times, namely, increasing the historical overtime times by 1;
step S311, determining whether the historical timeout times are greater than a preset time, and if so, executing step S312; if not, go to step S314;
step S312, determining as blocking;
step S313, controlling display or buzzing to prompt a user to clean the drainage filtering device;
in step S314, it is determined that there is no clogging.
In another embodiment, step S302 may also be to determine the draining time threshold according to the weight and type of the laundry.
