In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
As shown in fig. 2, the application provides a coffee powder grinding time control method of a coffee machine, comprising the following steps:
s1, presetting a reference parameter set in a coffee machine; wherein the reference parameter set includes: the method comprises the steps of presetting a plurality of parameters in a coffee machine before starting the coffee machine, wherein the parameters are respectively the reference coffee bean grinding time, the reference extraction hot water quantity and the reference extraction time;
s2, starting a coffee machine, grinding beans and extracting by the coffee machine according to the preset reference parameter set, and obtaining actual extraction time in the extraction process;
obtaining the actual extraction time, including:
s21, automatically pumping cold water into a pipeline by an extraction pump;
s22, heating cold water by a heating body, and then entering a brewing assembly for extraction;
and S23, measuring the passing hot water quantity by a flowmeter, and recording the extraction elapsed time as the actual extraction time when the passing hot water quantity reaches the preset reference extraction hot water quantity.
Here, there are two ways to record the time of extraction, which are respectively:
(1) The total time from the start to the stop of the extraction pump, namely the start time of the extraction pump is the start time, the stop time of the extraction pump is the end time, and the elapsed time is the actual extraction time;
(2) The total time from when the flow meter starts to pass the hot water flow to when the no water flow passes, namely the time from when the flow meter starts to pass the hot water flow is the starting time, the time when the no water flow passes is the ending time, and the time elapsed between the two times is the actual extraction time.
Wherein in the preset reference parameter set, the reference coffee bean grinding time is set according to the conventional coffee bean grinding time, for example, 1.5g/s;
the reference extraction hot water quantity is determined according to the quantity of the coffee powder theoretically ground in the set time.
The quantity of coffee liquid extracted by the coffee machine each time is programmed, for example 35ml of espresso coffee, and the operating time of the extraction pump is controlled according to the quantity of water metered by the flowmeter. The operation time of the extraction pump is started after the coffee powder enters the brewer and is compressed into a coffee powder cake, and is stopped after the preset amount of coffee liquid is reached.
And S3, comparing the obtained actual extraction time with the reference extraction time in the reference parameter set, and executing a subsequent processing step based on a comparison result.
Specifically, the subsequent processing steps are performed based on the comparison result, including:
step S31, when the actual extraction time deviates from the reference extraction time, adjusting the reference coffee bean grinding time;
it should be noted that, in order to avoid the influence of external factors, the processing method when the actual extraction time deviates from the reference extraction time includes:
step S311, when the actual extraction time deviates from the reference extraction time for the first time, the grinding time is not adjusted;
step S312, the actual extraction time is obtained continuously and compared with the reference extraction time, and after the rechecking condition is reached, the extraction average value of all the obtained actual extraction times is calculated, and the subsequent processing steps are executed based on the comparison of the extraction average value and the reference extraction time.
In particular to a special-shaped ceramic tile,
the extraction average value is larger or smaller than the reference extraction time, and the reference coffee bean grinding time is adjusted;
the extraction average value is equal to the reference extraction time, and the reference coffee bean grinding time is not adjusted.
Wherein, adjust reference coffee bean grinding time, include:
when the extraction average value is larger than the reference extraction time, reducing the grinding time of the next reference coffee beans;
and when the extraction average value is smaller than the reference extraction time, increasing the grinding time of the next reference coffee beans.
Furthermore, when the deviation between the extraction average value and the reference extraction time is large, the adjustment range of the reference coffee bean grinding time is large; when the deviation between the extraction average value and the reference extraction time is small, the adjustment range of the reference coffee bean grinding time is small. The deviation value and the adjustment amplitude are adjusted in the negative correlation direction, that is, negative adjustment is performed (polishing time is reduced) when the deviation is positive, and positive adjustment is performed (polishing time is increased) when the deviation is negative.
For example, if the extraction average value is compared with the reference extraction time, the reference coffee bean grinding time (reduced grinding time) is adjusted for 3 seconds if the extraction average value is greater than the reference extraction time for 5 seconds, and the reference coffee bean grinding time is adjusted for 2 seconds if the extraction average value is greater than the reference extraction time for 4 seconds; therefore, the grinding time of the reference coffee beans is adjusted according to the deviation of the extraction time, and the calibration speed and accuracy are improved.
Wherein, the rechecking condition is: the actual extraction time is obtained for three times, or at least three deviations occur when the actual extraction time is compared with the reference extraction time.
When either of the two compounding conditions is reached, then an average calculation and comparison is performed.
And S32, when the actual extraction time is not deviated from the reference extraction time, grinding is continued according to the reference coffee bean grinding time.
According to the coffee machine coffee powder grinding time control method provided by the application, the extraction time of the coffee machine is detected and compared with the reference extraction time, and then the grinding time of the grinder is automatically controlled and calibrated according to the deviation, so that the optimal control and adjustment of the reference coffee bean grinding time are realized, the automatic adjustment and calibration are realized, and the standard Italian espresso coffee beverage is manufactured through the standard control of the time, the temperature, the pressure and the single cup quantity parameters, so that the taste of coffee is unified and pure.

The computer readable storage medium has stored thereon a computer program which, when executed by a processor, is capable of performing a method for controlling the grinding time of coffee grounds in a coffee machine.
When in use, as shown in fig. 2, the coffee machine automatically adjusts the grinding time of the reference coffee beans according to the logic control method in fig. 2, and firstly, the grinding time of the reference coffee beans, the reference extraction hot water quantity and the reference extraction time are preset; then grinding the coffee beans by a grinder; grinding coffee beans into coffee powder, entering the brewing assembly 4 and compressing the coffee powder into a coffee cake; then the extraction pump 3 starts to pump cold water into the pipeline to provide power for coffee extraction; the flow meter 2 measures the amount of cold water flowing through, and the amount of hot water measured by the flow meter 2 is the amount of hot water because the amount of cold water is equal to the amount of hot water heated by the heating body 5; the heating body 5 heats water to enter the brewing assembly 4 to extract coffee; the flowmeter 2 measures the water passing amount and stops after reaching the preset hot water amount; simultaneously, automatically recording the actual extraction time; comparing the actual extraction time with the reference extraction time, and when the actual extraction time deviates from the reference extraction time, performing rechecking action, wherein rechecking means that three actual extraction times are obtained, or that the actual extraction time deviates from the reference extraction time at least three times; then calculating the extraction average value of all the obtained actual extraction times, and increasing the grinding time of the next reference coffee beans when the extraction average value is smaller than the reference extraction time; when the extraction average value is larger than the reference extraction time, reducing the grinding time of the next reference coffee beans; the actual extraction time is equal to the reference extraction time, and the reference coffee bean grinding time is not adjusted.
As shown in fig. 3, in order to provide a flow chart of the extraction pump of the coffee machine of the present application, the outlet flow of the electromagnetic vibration pump (extraction pump 3) decreases with the increase of the flow resistance. The flow resistance is increased due to the fact that the compactness of the powder cake is high due to the fact that the quantity of the coffee powder is large, so that the flow is reduced, and the extraction time is prolonged; on the contrary, the flow resistance is reduced due to the fact that the compactness of the powder cake is small due to the fact that the coffee powder is small, the flow is increased, and the extraction time is shortened.
