Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
Example one
As shown in fig. 1, the present embodiment provides a method for diagnosing clogging of a drain pipe filter, which includes the following steps:
s1, before draining, acquiring the amount of washing water in a washing drum of the washing machine, and acquiring a first preset draining speed corresponding to the amount of the stored washing water;
s2, in the drainage process, randomly obtaining a plurality of instantaneous drainage speeds of the drainage pipe, comparing and obtaining the maximum instantaneous drainage speed in the instantaneous drainage speeds, and if the maximum instantaneous drainage degree is less than or equal to a first preset drainage speed, giving out a prompt of blockage of a filter screen of the drainage pipe.
It can be understood that as the number of times the washing machine is used increases, debris such as clothes, thread scraps, etc. are gradually accumulated on the filter screen, resulting in clogging of the filter screen. When the filter screen is blocked, the drainage speed when the filter screen is blocked is lower than that when the filter screen is not blocked under the condition that the amount of washing water is the same. At the moment, in the drainage process, a plurality of instantaneous drainage speeds of the drainage pipe are randomly acquired, the maximum instantaneous drainage speed is obtained by comparing the instantaneous drainage speeds, if the maximum instantaneous drainage speed is less than or equal to a first preset drainage speed, the situation that the filter screen is blocked is indicated, and at the moment, a user is prompted to clean the filter screen in time. If the maximum instantaneous drainage speed is higher than the first preset drainage speed, the filter screen can be considered to be not blocked or the blocked degree is small, and the user is not prompted.
It should be noted that the first preset drainage speed is less than or equal to the drainage speed when the filter screen is not blocked, and the first preset drainage speed can be set according to actual needs.
Further, the first preset water discharge speed may be obtained through an experiment and stored in a controller of the washing machine. Specifically, when the filter screen is blocked by X%, the set washing water amount is the same each time, n maximum drainage speeds in the drainage process of n times are obtained, the average value of the n maximum drainage speeds after one maximum value and one minimum value are removed is aveN, the aveN is the first preset drainage speed, wherein n is more than or equal to 2, and X% is more than or equal to 0 and less than 100%. It is understood that the specific value of X% can be selected according to actual needs, and when X% ═ 0, it indicates that the filter screen is not blocked, and when X% > 0, it indicates that the filter screen is blocked. Further preferably, in this embodiment, n is 10, so that misjudgment in case of single drainage can be avoided, and the reason why the drainage speed is slow in the drainage process is many, such as: the drain pipe is blocked, bent and not put down, the drain valve is in failure and the like, so that the n value is set to 10, a maximum value and a minimum value are removed, and then the average value is obtained, the accuracy of the calculation result can be improved, and the accuracy of judging whether the filter screen is blocked or not is further improved. Of course, in other embodiments, n may also be an integer greater than 2 and less than 10, or an integer greater than 10.
It should be noted that the filter has a plurality of drainage holes, and thus the filter screen clogging X% means that the number of drainage holes clogged accounts for X% of the total number of drainage holes, or means that the area of the clogged drainage holes accounts for X% of the total area of drainage holes.
The filter screen blockage prompt can be prompted through a control panel of the washing machine, for example, the prompt is prompted by displaying characters on the control panel. The alarm mode is as follows: and sending alarm information to the mobile terminal through a network. So that the user can clean the filter screen in time.
Further, in this embodiment, the step of obtaining the amount of washing water in the washing tub of the washing machine before draining comprises: the weights of the washing cylinders before and after water inflow are respectively obtained, and then the washing water quantity is calculated. Specifically, the weight of the washing drum before and after water intake can be obtained by a weight sensor provided in the washing machine. Of course, in other embodiments, a flow meter may be disposed at the water inlet valve of the washing machine, and during the water inlet process, the total water amount entering the washing drum is detected and calculated by the flow meter, so as to obtain the washing water amount.
In summary, in the method for diagnosing clogging of a filter screen of a drain pipe according to the present embodiment, before draining, the amount of washing water in a washing drum of a washing machine is obtained, and a stored first preset draining speed corresponding to the amount of washing water is obtained; in the drainage process, a plurality of instantaneous drainage speeds of the drainage pipe are randomly acquired, the maximum instantaneous drainage speed in the instantaneous drainage speeds is acquired, if the maximum instantaneous drainage speed is less than or equal to a first preset drainage speed, a prompt of blockage of a filter screen of the drainage pipe is sent, and the prompt of blockage of the filter screen can be timely given to a user, so that the user can timely clean the filter screen, normal drainage of the washing machine is prevented from being influenced, and user experience is improved; and the method for diagnosing the blockage of the filter screen of the drain pipe has the advantages of fast value taking, less filter screen and high diagnosis efficiency.
The embodiment also provides a washing machine, and whether the drain pipe filter screen of the washing machine is blocked is judged by adopting the drain pipe filter screen blocking diagnosis method.
Furthermore, a filter screen and a flow rate detection unit are arranged in the drain pipe of the washing machine, and the flow rate detection unit is used for acquiring the instantaneous drainage speed of the drain pipe. The flow rate detection unit may be a flow rate meter electrically connected to a controller of the washing machine, and the controller stores a first preset drain speed and a second preset drain speed corresponding to each amount of washing water.
Example two
As shown in fig. 2, the method for diagnosing clogging of a drain pipe filtering net provided in this embodiment is basically the same as the method for diagnosing clogging of a drain pipe filtering net in the first embodiment, except that: after the amount of washing water in the washing drum of the washing machine is obtained, the method for diagnosing blockage of the filter screen of the drain pipe further comprises the steps of obtaining a second preset drainage speed corresponding to the amount of the stored washing water, wherein the second preset drainage speed is smaller than the first preset drainage speed, and if the maximum instantaneous drainage speed is larger than the second preset drainage speed and smaller than or equal to the first preset drainage speed, sending a filter screen blockage prompt and normally draining; and if the maximum instantaneous speed is less than or equal to the second preset drainage speed, stopping drainage and giving an alarm.
It can be understood that when the maximum instantaneous drainage speed is greater than the second preset drainage speed and less than or equal to the first preset drainage speed, the filter screen is blocked but drainage is not affected, at the moment, a filter screen blocking prompt and normal drainage can be sent to a user, and the user can select cleaning or continue to use according to actual conditions. When the maximum instantaneous drainage speed is less than or equal to the second preset drainage speed, the filter screen is blocked to a greater extent, normal drainage of the drainage pipe is influenced, and at the moment, drainage is stopped and an alarm is given to the user so that the user can clean the filter screen in time and the user experience is improved.
Further, if the maximum instantaneous drainage speed is greater than the first preset drainage speed, it indicates that the filter screen is not blocked or slightly blocked, and no prompt is given to the user at this time.
Further, in the present embodiment, the first preset water discharge speed and the second preset water discharge speed are a water discharge speed when the filter screen is blocked by X1% and a water discharge speed when the filter screen is blocked by X2% for the same amount of washing water, wherein X1% is smaller than X2%. Specifically, when the filter screen is blocked by X1%, the set washing water amount is the same each time, n maximum drainage speeds in the drainage process of n times are obtained, the average value of the n maximum drainage speeds after one maximum value and one minimum value are removed is aveNX1, and aveNX1 is the first preset drainage speed. When the filter screen is blocked by X2%, the set washing water amount is the same every time, n maximum drainage speeds in the drainage process of n times are obtained, the average value of the n maximum drainage speeds after one maximum value and one minimum value are removed is aveNX2, and aveNX2 is the second preset drainage speed. Further preferably, in the present embodiment, X1% is 25%, X2% is 50%, and in other embodiments, the specific values of X1% and X2% may be selected according to actual needs.
In addition, it is understood that a first preset drain speed, a second preset drain speed … …, an Mth preset speed, M being greater than or equal to 3, may be set to be decreased in sequence for the same amount of washing water, the first preset drain speed and the second preset drain speed … … correspond to X1%, X1% … … XM%, X1% < X2% < … … XM%, respectively, the user is prompted for the clogging degree of the filter screen by comparing the maximum instantaneous drainage rate with the first preset drainage rate, the second preset drainage rate … …, the mth preset rate, such as M equals 3, when the maximum instantaneous drainage speed is greater than the second drainage speed and less than or equal to the first drainage speed, the blockage degree of the filter screen is smaller, when the maximum instantaneous speed is greater than the third preset drainage speed and less than or equal to the second preset drainage speed, the light blockage degree of the filter screen is indicated to be medium; when the maximum instantaneous speed is less than or equal to the third preset drainage speed, the blockage degree of the filter screen is indicated to be larger.
The embodiment also provides a washing machine, and whether the drain pipe filter screen of the washing machine is blocked is judged by adopting the drain pipe filter screen blocking diagnosis method.
Furthermore, a filter screen and a flow rate detection unit are arranged in the drain pipe of the washing machine, and the flow rate detection unit is used for acquiring the instantaneous drainage speed of the drain pipe. The flow rate detection unit may be a flow rate meter electrically connected to a controller of the washing machine, and the controller stores a first preset drain speed and a second preset drain speed corresponding to each amount of washing water.
EXAMPLE III
The method for diagnosing blockage of a drain pipe filter screen provided by the embodiment is basically the same as the method for diagnosing blockage of a drain pipe filter screen in the first embodiment, and the difference is that: the method for diagnosing the blockage of the filter screen of the drain pipe provided by the embodiment further comprises the following steps: if the maximum instantaneous drainage speed is less than or equal to the first preset drainage speed, adding 1 to the drainage times of the washing machine, further judging whether the drainage times are more than the preset times, and if the drainage times are more than or equal to the preset times, stopping drainage and giving an alarm.
It can be understood that if the maximum instantaneous drainage speed is less than or equal to the first preset drainage speed, it indicates that the filter screen is blocked, and at this time, a user is prompted, but the blocking degree of the filter screen may still be relatively small, and the filter screen can still be continuously used, and the user may not timely clean the filter screen after receiving the prompt of the blockage of the filter screen. After a user uses the washing machine for multiple times, the filter screen is not cleaned, and in order to avoid the influence on the washing machine when the blockage degree of the filter screen is larger, when the water is drained every time, if the maximum instantaneous water drainage speed is smaller than or equal to the first preset water drainage speed after judgment, the water drainage frequency of the washing machine is added with 1, the water drainage frequency is compared with the preset frequency stored in the washing machine in advance, and if the water drainage frequency is larger than or equal to the preset frequency, the water drainage is stopped and an alarm is given. At this time, it is considered that after the drainage is performed for the preset number of times, the clogging degree of the filter screen reaches the degree that the filter screen must be cleaned, and the user must clean the filter screen.
The preset times can be obtained through a plurality of tests and can be set according to actual requirements, for example, when the sundries such as scraps, line sections and the like of the washed clothes are relatively less, the filter screen is relatively difficult to block, and the preset times are relatively larger at the moment. When the sundries such as scraps, line segments and the like of the washed clothes are relatively more, the filter screen is relatively easy to block, and the preset times are relatively smaller.
In summary, in the method for diagnosing clogging of a filter screen of a drain pipe according to the present embodiment, before draining, the amount of washing water in a washing drum of a washing machine is obtained, and a stored first preset draining speed corresponding to the amount of washing water is obtained; in the drainage process, a plurality of instantaneous drainage speeds of the drainage pipe are randomly acquired, the maximum instantaneous drainage speed in the instantaneous drainage speeds is acquired, if the maximum instantaneous drainage speed is less than or equal to a first preset drainage speed, a prompt that a filter screen of the drainage pipe is blocked is given, meanwhile, the drainage frequency of the washing machine is added by 1, whether the drainage frequency is greater than the preset frequency is further judged, and if the drainage frequency is greater than or equal to the preset frequency, drainage is stopped and an alarm is given. The filter screen blockage reminding device can prompt a user of the blockage of the filter screen in time, so that the user can clean the filter screen in time, the influence on normal drainage of the washing machine is avoided, and the user experience is improved; and the method for diagnosing the blockage of the filter screen of the drain pipe has the advantages of fast value taking, less filter screen and high diagnosis efficiency.
The embodiment also provides a washing machine, and whether the drain pipe filter screen of the washing machine is blocked is judged by adopting the drain pipe filter screen blocking diagnosis method.
Furthermore, a filter screen and a flow rate detection unit are arranged in the drain pipe of the washing machine, and the flow rate detection unit is used for acquiring the instantaneous drainage speed of the drain pipe. The flow rate detection unit may be a flow rate meter electrically connected to a controller of the washing machine, and the controller stores preset times corresponding to each amount of washing water.
