DETAILED DESCRIPTION

[0064] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0066] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0067] With the improvement of people's living standards, household appliances have entered thousands of households and become the most commonly used household appliances. The water inlet pipe of household appliances connects the faucet and household appliances. Tap water often contains impurities such as mud, heavy metals, etc. When impurities enter the washing machine through the water inlet pipe, they will not only make the washing machine's water box and other parts turn yellow and discolor, affecting the appearance and use, but also stain the clothes, causing damage to the clothes and making them unwearable.

[0068] The water inlet pipes of household appliances are usually equipped with filters to prevent foreign matter in the water from entering the water inlet valve and blocking the valve core. The holes of the filter mesh are generally small, and too dense filter mesh holes are easily blocked by impurities in the water, resulting in no water inlet or slow water inlet. When blockage occurs, the filter mesh needs to be cleaned in time, otherwise problems such as slow water inlet rate will occur.

[0069] Therefore, a method for handling the blockage of the water inlet pipe of a household appliance is needed to accurately determine whether the filter is blocked and remind the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0070] The present application provides a method for controlling household appliances, which obtains the water level value in the washing drum of the household appliance and determines whether the water level value exceeds a first preset water level value; if the water level value does not exceed the first preset water level value, then when the household appliance is washing or rinsing, the water inlet time when the water level value in the washing drum reaches the first preset water level value and the second preset water level value is recorded respectively, and the water inlet rate at that time is calculated. Finally, according to the water inlet rate at that time and the historical water inlet rate of the household appliance, it is determined whether the household appliance has a water inlet problem, and an early warning is issued when the household appliance has a water inlet problem. It realizes accurate judgment of whether the filter is blocked, and reminds the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0071] The principles and features of the embodiments of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present invention and are not used to limit the scope of the embodiments of the present invention.

[0072] Figure 1 The process of the household appliance control method provided by the present invention is Figure 1 ;like Figure 1 As shown, the household appliance control method specifically includes the following steps:

[0073] S101: Obtaining a water level value in a washing tub, and determining whether the water level value exceeds a first preset water level value.

[0074] Among them, the purpose of setting the first preset water level is to prevent the clothes put into the washing drum from absorbing water and causing errors in the calculation of the water inlet time and the water inlet speed. The first preset water level can be, for example, the reset water level of the water level sensor of the household appliance. At the same time, in order to further prevent the clothes from absorbing water and causing errors in the calculation of the water inlet time and the water inlet speed, the present application sets the household appliance to run the normal washing and care program when the washing program is running, and the judgment logic of whether the household appliance has a water inlet problem is not entered when the water is first inletted, and the judgment logic of whether the household appliance has a water inlet problem is entered when the household appliance is inletted for the second time. When the water level value in the washing drum reaches the first preset water level value, the clothes in the washing drum are in full contact with the water.

[0075] S102: If the water level value does not exceed the first preset water level value, then when the household appliance is washing or rinsing, the water inlet time when the water level value in the washing drum reaches the first preset water level value and the second preset water level value is recorded respectively, and the water inlet rate at that time is calculated, and the second preset water level value is greater than the first preset water level value.

[0076] Among them, the second preset water level value is higher than the first preset water level value, and the volume corresponding to the first preset water level and the second preset water level can be, for example, less than 5L. When the water level in the washing drum reaches the first preset water level, the clothes in the washing drum are already in full contact with the water, and when the water level in the washing drum reaches the second preset water level value, the clothes will not absorb excessive water, and then the water inlet rate of the household appliance at that time is calculated by obtaining the water inlet time when the water level in the washing drum reaches the first preset water level value and the second preset water level value. The selection of the above first set water level and the second set water level is to avoid errors in the measurement of the water inlet time and the calculation of the water inlet speed caused by the water absorption of the washed clothes. Therefore, the present application is set to record the water inlet time when the water level in the washing drum reaches the first preset water level value and the second preset water level value when the household appliance is washing or rinsing, and calculate the water inlet rate at that time to determine whether the household appliance has a water inlet problem.

[0077] S103: judging whether the household appliance has a water inflow problem according to the current water inflow rate and the historical water inflow rate of the household appliance, and issuing an early warning when the household appliance has a water inflow problem.

[0078] Among them, according to the current water inflow rate and the historical water inflow rate of the household appliance, it can be judged whether the household appliance has a water inflow problem. The water inflow problem includes that the water inflow pipe of the household appliance is blocked and / or has a trend of water inflow blockage. Specifically, by obtaining the rate difference between the current water inflow rate and the historical water inflow rate in the shortest time interval from the current time point; if the rate difference is greater than or equal to the preset difference, the water inflow blockage of the household appliance is determined; if the rate difference is less than the preset difference, according to the historical water inflow rate corresponding to each time interval and the current water inflow rate, it is determined whether the household appliance has a trend of blockage. It can be understood that the preset difference is the threshold value of the difference between the current water inflow rate of the household appliance and the historical water inflow rate in the shortest time interval from the current time point when the household appliance has a water inflow blockage problem preset in this application. If the rate difference between the current water inflow rate and the historical water inflow rate in the shortest time interval from the current time point is greater than or equal to the preset difference, it is determined that the household appliance has a water inflow blockage, otherwise it is still necessary to further determine whether the household appliance has a trend of water inflow blockage.

[0079] The household appliance control method provided in this embodiment obtains the water level value in the washing drum and determines whether the water level value exceeds the first preset water level value. If the water level value does not exceed the first preset water level value, then when the household appliance is washing or rinsing, the water inlet time when the water level value in the washing drum reaches the first preset water level value and the second preset water level value is recorded respectively and the water inlet rate at that time is calculated, and the second preset water level value is greater than the first preset water level value. According to the current water inlet rate and the historical water inlet rate of the household appliance, it is determined whether the household appliance has a water inlet problem, and an early warning is issued when the household appliance has a water inlet problem. It is realized to accurately determine whether the filter is blocked, and remind the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0080] Figure 2 is a flow chart of a second embodiment of a household appliance control method provided by the present invention, Figure 2 exist Figure 1 Based on this, the method for obtaining the water inflow rate is described in detail, such as Figure 2 As shown, the method includes:

[0081] S201: Recording the water inflow time when the water level in the washing tub reaches the first preset water level value and the second preset water level value respectively.

[0082] Among them, the second preset water level value is higher than the first preset water level value. When the water level in the washing tub reaches the first preset water level, the clothes in the washing tub are already in full contact with the water, and when the water level in the washing tub reaches the second preset water level value, the clothes will not absorb excessive water. The volume between the first preset water level and the second preset water level remains unchanged, and the water level sensor in the household appliance detects whether the water level in the household appliance reaches the first preset water level value and the second preset water level value. The time when the water level in the washing tub reaches the first preset water level value is the first time, and the time when it reaches the second preset water level value is the second time.

[0083] S202: Acquire a time difference according to a first time corresponding to the first preset water level value and a second time corresponding to the second preset water level value.

[0084] By setting the first preset water level value and the second preset water level value, the water volume of each water intake of the household appliance is the same, and then by obtaining the time difference between the first time corresponding to the first preset water level value and the second time corresponding to the second preset water level value, the water intake time when each water intake reaches the set water intake volume can be measured, and then the water intake speed of each water intake can be calculated according to the water intake volume and the water intake time. The water level sensor is used to detect whether the water intake level in the washing machine reaches the first set water level or the second set water level, and the time difference between the second time and the first time is obtained.

[0085] S203: Obtain the current water inflow according to the first preset water level value and the second preset water level value.

[0086] It can be understood that, because the second preset water level value is higher than the first preset water level value, when the water level in the washing tub reaches the first preset water level, the clothes in the washing tub are already in full contact with the water, and when the water level in the washing tub reaches the second preset water level value, the clothes will not absorb excessive water, so the current water intake can be obtained through the first preset water level value and the second preset water level value, and the current water intake can be, for example, 5L.

[0087] S204: Obtaining the current water inflow rate according to the current water inflow volume and the time difference.

[0088] The water inflow volume at that time is divided by the time difference to obtain the water inflow rate in units of L (liter) / min (minute). By comparing the current water inflow rate with the historical water inflow rate of the household appliance previously recorded, it can be determined whether the household appliance has a water inflow problem, and an early warning is issued when the household appliance has a water inflow problem, reminding the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0089] The household appliance control method provided in this embodiment records the water inflow time when the water level in the washing drum reaches the first preset water level value and the second preset water level value. The time difference is obtained according to the first time corresponding to the first preset water level value and the second time corresponding to the second preset water level value. The current water inflow volume is obtained according to the first preset water level value and the second preset water level value. The current water inflow rate is obtained according to the current water inflow volume and the time difference. The water inflow rate of the household appliance is accurately obtained, and then it is possible to judge whether the household appliance has a water inflow problem according to the current water inflow rate and the historical water inflow rate of the household appliance, and remind the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0090] Figure 3 is a flow chart of a third embodiment of a household appliance control method provided by the present invention; Figure 3 exist Figure 1 Based on the above, the method for determining whether a household appliance has a water inflow problem is described in detail, such as Figure 3 As shown, the method includes:

[0091] S301: Obtain historical water inflow rates corresponding to a plurality of different time intervals before the current time.

[0092] Among them, the present application sets a plurality of different time intervals for storing and dividing the historical water inflow rate of the household appliance. The time intervals may be divided into, for example, 5 days, 10 days, 20 days, 30 days, and 60 days, and the present application does not limit this. By dividing the plurality of different time intervals, it is possible to obtain whether the water inflow rate of the household appliance is gradually decreasing or decreasing precipitously according to the corresponding historical water inflow rate, and then determine whether the household appliance has water inflow blockage or water inflow blockage trend.

[0093] S302: Obtain the rate difference between the current water inflow rate and the historical water inflow rate in the shortest time interval.

[0094] Among them, by obtaining the rate difference between the current water inflow rate and the historical water inflow rate in the shortest time interval, it can be determined whether the household appliance has a cliff-like drop in water inflow rate caused by the blockage of the water inlet pipe. For example, if the time interval is divided into water inflow rate records within 5 days, 10 days, 20 days, 30 days, and 60 days, then the water inflow rate in the shortest time interval is the water inflow rate within 5 days. The historical water inflow rate is the average water inflow rate obtained by averaging the water inflow rates of multiple water inflows in the time interval, wherein the starting points of the multiple time intervals are different and the end point is the current time.

[0095] S303: Determine whether the rate difference is less than a preset difference; if so, execute S305; if not, execute S304.

[0096] Among them, the preset difference is the threshold value of the difference between the current water inlet rate of the household appliance and the historical water inlet rate in the shortest time interval from the current time point when the household appliance preset in this application has a water inlet blockage problem. By judging whether the rate difference is less than the preset difference, it can be judged whether the household appliance has a cliff-like drop in water inlet rate caused by water inlet pipe blockage.

[0097] S304: judging whether the household appliance has a clogging trend according to the historical water inflow rate corresponding to each time interval and the current water inflow rate.

[0098] Among them, if the rate difference between the current water inlet rate and the historical water inlet rate of the shortest time interval from the current time point is less than the preset difference, it is determined that the household appliance does not have a short-term water inlet rate cliff-like drop problem caused by water inlet blockage, and it is still necessary to further determine whether the household appliance has a water inlet pipe blockage trend. The method for determining whether the household appliance has a water inlet pipe blockage trend can be, for example, determining the water inlet efficiency deviation corresponding to each time interval based on the historical water inlet rate and the current water inlet rate in each time interval; and judging whether the household appliance has a blockage trend based on the water inlet efficiency deviation corresponding to each time interval.

[0099] S305: Determine whether the water inlet of the household appliance is blocked.

[0100] Among them, if the difference between the current water inlet rate and the historical water inlet rate in the shortest time interval from the current time point is greater than or equal to the preset difference, it can be determined that the household appliance has a water inlet pipe blockage caused by a blockage in the water inlet pipe. This situation indicates that the water inlet valve is now seriously blocked, and it is necessary to control the household appliance to alarm, thereby reminding the user to clean the water inlet valve in time.

[0101] The household appliance control method provided in this embodiment obtains the historical water inlet rate corresponding to each of the multiple different time intervals before the current time. Obtain the rate difference between the current water inlet rate and the historical water inlet rate in the shortest time interval. Determine whether the rate difference is less than a preset difference; if so, determine that the water inlet of the household appliance is blocked. If not, determine whether the household appliance has a blocking trend based on the historical water inlet rate corresponding to each time interval and the current water inlet rate. Accurately determine whether the household appliance is blocked or has a blocking trend, and then determine whether the filter is blocked, and remind the user to replace or clean the filter in time to ensure the normal use of the household appliance.

[0102] Figure 4 The process diagram of the fourth embodiment of the household appliance control method provided by the present invention is as follows Figure 4 exist Figure 3 Based on this, the method of judging whether there is a blocking trend of household appliances is described in detail, such as Figure 4 As shown, the method includes:

[0103] S401: Determine the water inlet efficiency deviation corresponding to each time interval according to the historical water inlet rate of each time interval and the current water inlet rate.

[0104] Among them, if the rate difference between the current water inflow rate and the historical water inflow rate of the shortest time interval from the current time point is less than the preset difference, it is determined that the household appliance does not have a short-term water inflow rate cliff-like drop problem caused by water inflow blockage, and it is still necessary to further determine whether the household appliance has a water inlet pipe blockage trend. For example, when the number of time intervals is 3, the water inflow efficiency deviation corresponding to each time interval is determined based on the historical water inflow rate and the current water inflow rate of each time interval, and it can be determined whether the water inflow rate of the household appliance is gradually decreasing within the time interval, and then it can be inferred whether the household appliance has a water inflow blockage trend.

[0105] S402: Obtain a first difference between a water inlet efficiency deviation corresponding to the third time interval and a water inlet efficiency deviation corresponding to the second time interval.

[0106] Among them, if the time interval is divided into 5 days, 10 days, and 20 days, the third time interval is 20 days, and the second time interval is 10 days. The water inlet efficiency deviation corresponding to the third time interval is the difference between the water inlet rate of the household appliance in the third time interval and the current water inlet rate; the water inlet efficiency deviation corresponding to the second time interval is the difference between the water inlet rate of the household appliance in the second time interval and the current water inlet rate. By obtaining the first difference between the water inlet efficiency deviation corresponding to the third time interval and the water inlet efficiency deviation corresponding to the second time interval, the change trend of the current water inlet rate of the household appliance compared with the water inlet rates in the third time interval and the second time interval can be determined.

[0107] S403: Obtain a second difference between the water inlet efficiency deviation corresponding to the second time interval and the water inlet efficiency deviation corresponding to the first time interval.

[0108] Among them, if the time interval is divided into 5 days, 10 days, and 20 days, the second time interval is 10 days, and the first time interval is 5 days. The water inlet efficiency deviation corresponding to the second time interval is the difference between the water inlet rate of the household appliance in the second time interval and the current water inlet rate; the water inlet efficiency deviation corresponding to the first time interval is the difference between the water inlet rate of the household appliance in the first time interval and the current water inlet rate. By obtaining the second difference between the water inlet efficiency deviation corresponding to the second time interval and the water inlet efficiency deviation corresponding to the first time interval, the change trend of the current water inlet rate of the household appliance compared with the water inlet rates in the second time interval and the first time interval can be determined.

[0109] S404: If the second difference is smaller than the first difference, it is determined that the household appliance has a blocking trend.

[0110] If the second difference is smaller than the first difference, it is determined that the household appliance has a tendency to be blocked from the third time interval, the second time interval to the current water inlet. Because, in general, when the water inlet valve of the household appliance is blocked, it will become more and more blocked as the number of washings increases. If the second difference is smaller than the first difference, it indicates that the water inlet efficiency of the household appliance is getting lower and lower, and it can be inferred that the household appliance has a tendency to be blocked.

[0111] Preferably, when a household appliance has a water inflow problem, the household appliance can be controlled to emit a buzzer alarm and stop working, and the household appliance control panel can be controlled to display that the household appliance has a water inflow problem, prompting the user whether the water inlet pipe needs to be cleaned. For example, when it is determined that the household appliance has a water inflow problem, the user can be reminded by voice + flashing lights, and when it is determined that the water source is not connected, the user can be warned by the alarm light being always on. Alternatively, when it is determined that the water inlet valve is blocked, the user can be reminded by an interval buzzer alarm, and when it is determined that the water source is not connected, the user can be reminded by a continuous buzzer alarm.

[0112] The household appliance control method provided in this embodiment determines the water inlet efficiency deviation corresponding to each time interval according to the historical water inlet rate of each time interval and the current water inlet rate. Obtain a first difference between the water inlet efficiency deviation corresponding to the third time interval and the water inlet efficiency deviation corresponding to the second time interval. Obtain a second difference between the water inlet efficiency deviation corresponding to the second time interval and the water inlet efficiency deviation corresponding to the first time interval. If the second difference is less than the first difference, it is determined that the household appliance has a clogging trend. This achieves accurate judgment of whether the household appliance has a clogging trend, and then judges whether the filter is clogged, and reminds the user to replace or clean the filter in time to ensure the normal use of the household appliance.
