As shown in fig. 1 to 5, the water inflow control method of a dish washer provided by the invention comprises the following steps:
S1, starting a water inlet program;
s2, starting water inflow, and starting timing when the first inflection point A appears in the water level frequency signal f;
S3, judging whether the water level frequency signal f has a second inflection point B, if so, ending the timing, and calculating the water inflow in unit time according to the timing, if not, continuing water inflow.
The water inlet control method of the dish washer utilizes the fact that the volume of the water containing cavity is smaller than that of the dish washer 1, the accuracy of the change of the water level frequency signal f detected in the water inlet process is higher, nodes for starting and ending water inlet in the water containing cavity are determined, water inlet quantity in unit time is obtained, the water inlet process of the dish washer 1 is controlled, and the water inlet accuracy of the dish washer 1 is improved.
Example 1
As shown in fig. 1 and 2, the water inlet control method of the dish washer provided in this embodiment includes the following steps:
S1, starting a water inlet program;
s2, starting water inflow, and starting timing when the first inflection point A appears in the water level frequency signal f;
S3, judging whether the water level frequency signal f has a second inflection point B, if so, ending the timing, and calculating the water inflow in unit time according to the timing, if not, continuing water inflow.
In particular, the dishwasher 1 comprises a water-containing chamber defining an open-top water-storage chamber, preferably the dishwasher 1 may comprise a liner forming a washing chamber, in which racks are provided, in which dishes, utensils and other cutlery can be placed for washing, the water-containing chamber being provided below the liner, the volume of the water-containing chamber being relatively small compared to the liner, in which washing or rinsing water is collected after entering the liner, from which washing or rinsing water can be pumped out by a pump to respective spray arms mounted in the interior of the liner, so as to spray the washing or rinsing water under pressure onto the dishes, utensils and other cutlery accommodated in the racks. Because the volume of the water containing chamber is smaller, the accuracy of detecting the water level frequency signal f in the water inlet process is higher, in the embodiment, the water inlet amount of the dish washer 1 in unit time is calculated according to the water inlet time of the water containing chamber by judging the time from the start of water inlet of the water containing chamber to the time when the washing water fills the water containing chamber, namely, the time required by quantitative water inlet of the water containing chamber under the condition that the volume of the water containing chamber is known.
In detail, as shown in fig. 2, in a graph of a water level frequency signal f-time T (f-T), a water inlet program starts to run, water inlet starts, when a first inflection point A appears in the water level frequency signal f in the water containing chamber is detected, the water containing chamber is considered to start water inlet, and the dish washer 1 is controlled to start timing, and at the moment, the time is T1;
judging whether a second inflection point B appears in a water level frequency signal f in the water containing chamber in the water inlet process of the water containing chamber, if so, considering that the water inlet process of the water containing chamber is finished, namely, the water containing chamber is full of washing water, and controlling the dish washer 1 to finish timing, wherein the time is time T2;
and the time required for the water containing chamber from the beginning of water inflow to the end of water inflow can be calculated according to the following formula:
ΔT＝T2-T1
Because the volume of the water containing chamber of the dish washer 1 is fixed, the water inflow Q of the water containing chamber in unit time can be calculated according to the following formula assuming that the volume of the water containing chamber is Q1:
If the second inflection point B is not detected in the water level frequency signal f in the water containing cavity, water is continuously fed until the second inflection point B is detected in the water level frequency signal f in the water containing cavity.
Further, this embodiment detects water level frequency signal f in real time through pressure sensor, and pressure sensor sets up in flourishing water chamber, and preferably, pressure sensor sets up in flourishing water chamber's bottom, and the water level frequency signal f of detection is more accurate.
As shown in fig. 1 and 2, when water inflow is not started, the pressure sensor does not detect pressure information, the converted water level frequency signal f is the maximum water level frequency, after water inflow is started, washing water of a part of model dish washer 1 does not immediately enter the water containing cavity, but passes through a path in the inner container of the dish washer 1, so that before the washing water enters the water containing cavity, the water level frequency signal f detected by the dish washer 1 keeps the maximum water level frequency for a period of time, when the washing water enters the water containing cavity, the pressure sensor detects the pressure information, the converted water level frequency signal f starts to drop, the first inflection point A of the water level frequency signal f is obtained at the moment, and when the dish washer 1 detects the first inflection point A, timing is obtained at the moment T1;
The water level frequency signal f rapidly descends along with the continuous entering of the washing water into the water containing cavity, the change curve of the water level frequency signal f is in a straight line descending trend, when the water containing cavity reaches the maximum volume of the water containing cavity, the reduction of the water level frequency signal f converted by the pressure sensor starts to slow down, the descending trend of the change curve of the water level frequency signal f gradually slows down, the second inflection point B of the water level frequency signal f is the moment, the dish washer 1 is controlled to finish timing, and the moment T2 is the moment.
Preferably, the maximum water storage capacity of the water containing chamber is stored in the water inlet program of the dish washer 1, when the dish washer 1 judges the node of the water containing chamber for starting and ending water inlet, the water inlet time delta T required by filling the water containing chamber with washing water is calculated according to the water inlet time delta T, and the water inlet capacity q of the water containing chamber per unit time is calculated according to the following formula by the maximum water storage capacity of the water containing chamber stored in the water inlet program of the dish washer 1:
example two
The water inlet control method of the dish washer provided by the embodiment is complementary to the first embodiment.
As shown in fig. 1, a dishwasher water inlet control method further includes, before water inlet, the following operations: the total amount of the water inlet is set,
S4, calculating the residual water inlet time according to the total water inlet amount and the water inlet amount in unit time, and controlling the dish washer 1 to feed water according to the residual water inlet time;
S5, judging whether the residual water inlet time is reached, if so, ending water inlet, executing the next program according to program setting, namely executing the residual stage of the washing program, and if not, continuing water inlet.
In detail, a water inlet program starts to run, water inlet starts, when a water level frequency signal f in a water containing cavity is detected to have a first inflection point A, the water containing cavity is considered to start to enter water, and a dish washer 1 is controlled to start timing, and at the moment, the time is T1;
judging whether a second inflection point B appears in a water level frequency signal f in the water containing chamber in the water inlet process of the water containing chamber, if so, considering that the water inlet process of the water containing chamber is finished, namely, the water containing chamber is full of washing water, and controlling the dish washer 1 to finish timing, wherein the time is time T2;
and the time required for the water containing chamber from the beginning of water inflow to the end of water inflow can be calculated according to the following formula:
ΔT＝T2-T1
Because the volume of the water containing chamber in the dish washer 1 is certain, the water inflow Q of the water containing chamber in unit time can be calculated according to the following formula assuming that the volume of the water containing chamber is Q1:
If the second inflection point B is not detected in the water level frequency signal f in the water containing cavity, water is continuously fed until the second inflection point B is detected in the water level frequency signal f in the water containing cavity.
Assuming that the total amount of water intake set by a user or the total amount of water intake in a washing program set in the dishwasher 1 is Q2, the accuracy of detecting the water level frequency signal f by using the pressure sensor is lowered due to the fact that the water intake exceeding the capacity of the water holding chamber is enlarged in the cavity of the inner container of the dishwasher 1, the water intake cannot be directly judged by adopting a method of judging the sampling value of the pressure sensor, and therefore, the total water intake time T3 required for the total amount of water intake can be calculated by adopting the following formula according to the obtained water intake amount per unit time:
The residual water inlet time T4 can be obtained according to the method:
T4＝T3-ΔT
and controlling the dish washer 1 to continue water feeding, starting timing, judging whether the residual water feeding time reaches the required residual water feeding time T4, if so, ending water feeding, and executing the next program according to program setting, namely executing the residual stage of the washing program, if not, continuing water feeding until the required residual water feeding time T4 is reached, wherein the total water feeding amount is the target total water feeding amount set by the end user or the target total water feeding amount preset by the washing program.
Example III
The difference between this embodiment and the second embodiment is that:
In this embodiment, assuming that the total amount of water intake set by the user or the total amount of water intake in the washing program set in the dishwasher 1 is Q2, the accuracy of detecting the water level frequency signal f by the pressure sensor is reduced due to the fact that the inner container cavity of the dishwasher 1 is enlarged, and the water intake cannot be directly determined by a method of determining the sampling value of the pressure sensor, so that the required residual water intake Q3 can be calculated according to the maximum water storage capacity of the water containing chamber stored in the washing program of the dishwasher 1, that is, the volume of the water containing chamber:
Q3＝Q2-Q1
And then, according to the obtained water inflow in unit time, calculating the residual water inflow time T4 required for water inflow to the required residual water inflow Q3 by adopting the following formula:
and controlling the dish washer 1 to continue water feeding, starting timing, judging whether the residual water feeding time reaches the required residual water feeding time T4, if so, ending water feeding, and executing the next program according to program setting, namely executing the residual stage of the washing program, if not, continuing water feeding until the required residual water feeding time T4 is reached, wherein the total water feeding amount is the target total water feeding amount set by the end user or the target total water feeding amount preset by the washing program.
Example IV
The water inlet control method of the dish washer 1 provided by the implementation is that on the basis of the first embodiment, the second embodiment or the third embodiment, the following steps are added in the step S2:
As shown in fig. 3, step S2 further includes step S20, before water inflow is started, detecting a water level frequency signal f, determining whether the water level frequency signal f at this time is at a set maximum value, if not, starting water inflow, if not, executing a water drainage program, after water drainage is finished, continuing to detect the water level frequency signal f, and circulating in this way until the set maximum value of the water level frequency signal f is detected.
The water inlet time of the water containing chamber judged by the dish washer 1 is error, and the water inlet precision of the dish washer 1 is affected when the water inlet time is calculated according to the maximum volume of the water containing chamber, so that the water inlet precision of the dish washer 1 is not enough, and the washing effect is affected.
Specifically, due to the influence of the detection accuracy and the environmental factors, the maximum value of the water level frequency signal f is not a specific value, but a section value, and as long as the detected water level frequency signal f is within the section, the detected water level frequency signal f can be considered to be at the maximum value.

Preferably, the water level detection module 102 includes a pressure sensor disposed at the bottom of the water containing chamber.
When water inflow is not started, the pressure sensor does not detect pressure information, the converted water level frequency signal f is the maximum water level frequency, after water inflow is started, the pressure sensor detects the pressure information, the converted water level frequency signal f starts to descend, and the converted water level frequency signal f is the first inflection point A of the water level frequency signal f;
the water level frequency signal f rapidly drops along with the increase of water inlet, and when the water containing chamber reaches the maximum water storage capacity, the reduction of the water level frequency signal f converted by the pressure sensor starts to slow down, and the water level frequency signal f is a second inflection point B.
