Under the condition of too small or unstable water pressure, for example, in rural areas, high buildings and other scenes, the phenomenon of insufficient water pressure often occurs, and because the impulsive force of water flowing into the detergent box is insufficient, the risk that the detergent in the detergent box cannot be washed cleanly exists in a washing stage, so that part of residual detergent still enters a washing barrel in a rinsing stage, and further, the residual detergent in clothes after washing is over-standard is caused, and the user experience and health are affected.
In order to solve the technical problems, the application provides a water inlet control method of a detergent box, namely, when a water inlet valve is opened and water is continuously fed, abnormal water pressure is detected, and the water inlet valve is controlled to be intermittently opened for a plurality of times so as to realize intermittent water feeding for a plurality of times.
The technical effects which can be achieved based on the above description scheme are as follows:
in the washing water inlet stage, through detecting water inlet water pressure conditions, when water pressure abnormality is detected, intermittent water inlet is performed for a plurality of times through control, as residual detergent is generally deposited at the bottom of the detergent box, and water in the detergent box can be thoroughly discharged into the washing barrel in each intermittent process, especially in the period of closing the water inlet valve, so that the detergent box is filled with water again in the period of opening the water inlet valve in the next intermittent process, and the water in the detergent box is thoroughly discharged into the washing barrel again in the period of closing the water inlet valve, so that the frequency of contact between the water and the bottom of the detergent box can be increased, the entering water can be ensured to directly impact the bottom of the detergent box in each intermittent process, the detergent at the bottom of the detergent box is flushed clean, and the phenomenon that residual detergent in the detergent box still enters the washing barrel in the rinsing stage is avoided, so that the residual detergent in clothes is out of standard after washing is finished, and the user experience and health are influenced. If the water is continuously fed, the water entering the detergent box is continuously accumulated in the detergent box, and the water level is continuously increased, so that the water capable of directly flushing the bottom of the detergent box is limited, namely the water entering the detergent box in a continuous water feeding mode has lower flushing efficiency on the bottom of the detergent box.
In order to enable those skilled in the art to better understand the solution of the present application, the following description will clearly and completely describe the solution of the embodiment of the present application in conjunction with specific embodiments of the water inlet control flow.
Fig. 1 is a flow chart showing an embodiment of a water inlet control method of a detergent box according to an exemplary embodiment of the present application, in which a detergent in the detergent box is used to wash laundry while being discharged into a washing tub with water during a washing stage. As shown in fig. 1, the water inflow control method comprises the following steps:
step 101: and detecting whether the water pressure is abnormal or not in the process of continuously feeding water when the water inlet valve is opened.
The water inlet process of step 101 belongs to a water injection process of a washing stage of the clothes treatment equipment, during the opening period of the water inlet valve, water flows into the detergent box first, water and detergent form a mixed solution, when the detergent box is full of water and overflows, the mixed solution starts to overflow from the water outlet and flows into the washing barrel, and thus, the water flowing into the detergent box continuously overflows from the water outlet and flows into the washing barrel.
In the embodiment of the application, the abnormal water pressure refers to the phenomenon that the water pressure is too small or unstable, for example, the water pressure is too small or unstable in rural areas or high floors.
It is noted that when the water pressure is too low or unstable, water flows into the detergent box, but the impulse of water is weakened, and the water inflow per unit time is reduced.
For a specific implementation process of detecting whether the water pressure is abnormal, reference may be made to the description of the following embodiments.
Step 102: after the abnormal water pressure is determined to be detected, the water inlet valve is controlled to be opened intermittently for a plurality of times so as to realize intermittent water inlet for a plurality of times.
In one possible implementation, for each intermittent opening process of the water inlet valve, a preset intermittent rule is obtained, and the water inlet valve is controlled to be opened and closed according to the intermittent rule so as to complete one intermittent process.
The intermittent rule comprises an opening time and a closing time of the water inlet valve, and the opening time and the closing time can be set according to the specific size of the detergent box.
In the embodiment of the application, the opening time length in the intermittent rule is required to ensure that water can at least cover the bottom wall of the detergent box in the time range, and the closing time length in the intermittent rule is required to ensure that water in the detergent box can be completely emptied in the time range, so that the water flowing into the detergent box can be flushed to the bottom of the detergent box in the next intermittent process.
Therefore, the determination of the opening time and the closing time of the water inlet valve in the intermittent rule can be obtained through multiple experimental tests.
Wherein for specific control implementation of the intermittent water inlet for a plurality of times, reference can be made to the relevant description in the following embodiments.
In another possible implementation, after step 102 is performed, it is further determined that the water level in the tub has not reached the wash water level, and the water inlet valve is continuously controlled to open for continuous water inlet until the wash water level is reached and the water inlet valve is closed.
The washing water level may be a water level of the laundry selected by the user on the control panel, or may be a water level required for the laundry to be automatically recognized by the laundry treating apparatus according to the laundry in the washing tub, which is not particularly limited in the present application.
Therefore, the service life of the inlet valve is limited, so that the inlet valve is controlled to be intermittently opened for a certain number of times, so that the detergent in the detergent box is ensured to be thoroughly discharged into the washing barrel, and then the water continuously flows in until reaching the washing water level, rather than continuously controlling the intermittent water inflow until reaching the washing water level, thereby reducing the opening and closing times of the inlet valve and prolonging the service life of the inlet valve.
Further, when the water level in the washing tub reaches the washing water level, it indicates that the water intake of the washing tub is completed, and the water in the washing tub is doped with the detergent discharged from the detergent box, so that the washing process can be performed, and the washing of the laundry in the washing tub can be realized.
After detecting that the water pressure is not abnormal, the water inlet valve is kept open until the water level in the washing barrel reaches the washing water level, and the water inlet valve is closed.
Thus, the water inlet control flow shown in the figure 1 is completed, in the washing water inlet stage, through detecting the water inlet water pressure condition, when detecting water pressure abnormality, intermittent water inlet is performed for a plurality of times through control, as residual detergent is generally deposited at the bottom of the detergent box, and water in the detergent box can be thoroughly discharged into the washing barrel in each intermittent process, especially in the period of closing the water inlet valve, so that the detergent box is filled with water again in the period of opening the water inlet valve in the next intermittent process, and the water in the detergent box is thoroughly discharged into the washing barrel again in the period of closing the water inlet valve, so that the frequency of contact between the water and the bottom of the detergent box can be increased, therefore, the entering water can be ensured to directly impact the bottom of the detergent box in each intermittent process, the detergent at the bottom of the detergent box is flushed clean, the residual detergent in the detergent box still enters the washing barrel in each intermittent process, the phenomenon that the residual detergent in the clothes after washing is finished is over-standard in the rinsing stage is avoided, and the user experience and health are influenced. If the water is continuously fed, the water entering the detergent box is continuously accumulated in the detergent box, and the water level is continuously increased, so that the water capable of directly flushing the bottom of the detergent box is limited, namely the water entering the detergent box in a continuous water feeding mode has lower flushing efficiency on the bottom of the detergent box.
Fig. 2A is a schematic flow chart of another embodiment of a water inlet control method for a detergent box according to an exemplary embodiment of the present application, and on the basis of the embodiment shown in fig. 1, as shown in fig. 2A, the water inlet control method for a detergent box includes the following steps:
step 201: and determining the detection water level according to the washing water level, and determining the actual use time of the water level in the washing barrel reaching the detection water level in the continuous water inlet process of the opened water inlet valve.
In this embodiment, the detected water level is smaller than the washing water level, that is, the present application realizes the detection of the water pressure abnormality by completing a part of the water inflow.
It is to be understood that the detected water level at which a part of the water inflow is completed may be half, quarter, third, etc. of the washing water level, and the method of determining the detected water level is not particularly limited in the present application, for example, half of the washing water level may be preferable as the detected water level.
In an alternative embodiment, referring to fig. 2B, the actual time determination process for completing a portion of the influent water includes the following steps:
step 2011: when the start of water inflow of the washing tub is detected, the timing is started.
The water inlet valve is opened for a period of time to enable the washing barrel to start water inlet after the washing box is filled with water, so that timing is started when the water inlet of the washing barrel is detected in the step, and accuracy in practical use is guaranteed.
Step 2012: during the time counting, the water level in the washing tub is determined to reach the detected water level, and the time counting is ended.
Wherein during the time counting, the water level in the washing tub needs to be detected in real time for monitoring whether the detected water level is reached.
Step 2013: the difference between the start timing time and the end timing time is taken as the actual time.
Wherein, the actual time is the actual time required for the laundry treating apparatus to complete the water inflow of the detected water level, and the actual time is related to the actual water pressure condition.
For the processes from step 2011 to step 2013, the actual water pressure condition cannot be obtained, and therefore the actual water inflow in unit time cannot be obtained, so that the actual time determination of completing a part of water inflow is realized by detecting the water inflow condition in the washing barrel in real time, and the method is convenient and accurate.
Step 202: and acquiring theoretical time spent when the water inlet of the washing barrel reaches the detection water level.
The theoretical time of use refers to the time required by the clothes treatment equipment to finish the water inflow theory of the water level under the normal water pressure condition.
In an alternative embodiment, referring to FIG. 2C, the theoretical time-consuming determination of a portion of the incoming water includes the steps of:
step 2021: and obtaining the water inflow per unit time under the preset water pressure condition.
The preset water pressure condition is a normal water pressure condition, namely a standard water pressure provided by municipal administration. That is, the water inflow per unit time belongs to the theoretical calculation value.
For example, under normal water pressure conditions of 0.2MPa to 0.3MPa, the water inflow per unit time is measured to be 11L/min to 12L/min.
Step 2022: and obtaining the required water quantity of the water entering the washing barrel to reach the detection water level.
It will be appreciated that the required amount of water is related to the size of the washing tub in addition to the required water level, and the specific calculation of the required amount of water to reach the detected water level is not particularly limited by the present application.
Step 2023: and determining theoretical time by using the required water quantity and the water inflow in unit time.
The theoretical time is a value obtained by dividing the required water amount by the water inflow amount per unit time.
With respect to the above-described processes of steps 2021 to 2023, since the standard water pressure conditions, the tub size parameters, and other structural parameters in the laundry treatment apparatus all belong to known parameters, the theoretical water inflow per unit time and the required water amount can be obtained by using these known parameters, and thus the theoretical time consumption can be obtained.
Step 203: determining whether there is a water pressure abnormality according to the actual time and the theoretical time, if not, executing step 204, and if so, executing step 205.
In this embodiment, if there is a problem in that the water pressure is too small or unstable, the water flow becomes slow, and thus the required time increases.
Based on this, it is possible to determine whether or not there is a water pressure abnormality by comparing the actual time of use with the theoretical time of use, that is, if the actual time of use is greater than the theoretical time of use, it is indicated that there is a water pressure abnormality, and if the actual time of use is less than or equal to the theoretical time of use, it is indicated that there is no water pressure abnormality.
Step 204: and continuously keeping the water inlet valve open until the water level in the washing barrel reaches the washing water level, and closing the water inlet valve.
If the abnormal water pressure phenomenon does not exist, the fact that the detergent in the detergent box is continuously flushed by utilizing the impact force of water can flow into the washing barrel along with the water, intermittent water inflow is not needed, and the water inlet valve is kept open until water inflow is completed.
Step 205: and determining the intermittent times corresponding to the difference between the actual time and the theoretical time.
If there is abnormal water pressure, it means that the detergent in the detergent box cannot be washed out due to insufficient water impact, and the water inlet mode needs to be changed, that is, the intermittent water inlet mode is used for multiple times, so as to effectively reduce the residual detergent in the detergent box.
It should be noted that, the larger the difference between the actual use and the theoretical use, the more serious the phenomenon of unstable water pressure is, the more detergent remains in the detergent box, and the residual detergent can be discharged to the washing barrel only by intermittent water inlet flushing for many times; the smaller the difference between the actual use and the theoretical use, the less serious the phenomenon of unstable water pressure is, so that the detergent residue in the detergent box is less, and the residual detergent can be discharged to the washing barrel by intermittent water inlet with less times. That is, the larger the difference, the more intermittent water inflow times are required.
For the process of determining the number of pauses, in one possible implementation, if the difference is greater than a preset threshold, determining the number of pauses as a first preset number of pauses; and determining the intermittent times as second preset times according to the difference value smaller than or equal to the preset threshold value.
Wherein the first preset times are greater than the second preset times.
Step 206: and controlling the water inlet valve to be opened intermittently according to the intermittent times so as to realize intermittent water inlet for a plurality of times.
For a specific limitation of the intermittent opening in step 206, reference may be made to the description related to step 101 in the above embodiment, and the present application will not be described in detail here.
