The invention provides a control method of an ice maker, the ice maker comprises an ice storage barrel 10 and an ice outlet screw 20 arranged on the ice storage barrel 10, and the ice outlet screw 20 is used for conveying ice blocks to an ice outlet.

In an embodiment of the present invention, as shown in fig. 1 to 6, a method of controlling an ice maker includes:

s1: controlling the ice discharging screw rod 20 to rotate forwards for a first preset number of turns;

s2: and after the first preset time, controlling the ice discharging screw rod 20 to rotate reversely for a second preset number of turns so as to stir the ice blocks.

In the present embodiment, the ice discharging screw 20 rotates forward to drive the ice cubes to move toward the ice outlet, and the ice discharging screw 20 rotates backward to drive the ice cubes to move away from the ice outlet; or the ice cubes can be driven by forward rotation to move away from the ice outlet, and can be driven by reverse rotation to move towards the ice outlet; the ice discharging screw 20 is not limited to this, and only the ice discharging screw 20 needs to rotate in different directions. The ice discharging screw rod 20 rotates forwards and then rotates backwards, so that ice blocks can be stirred and can be prevented from being conveyed towards one direction under the working condition of non-ice taking, therefore, the ice blocks can effectively shake in the ice storage barrel 10, the adhesion of the ice blocks is reduced, and the smoothness and the stability of ice discharging are improved; meanwhile, the stirring process is simulated through the forward and reverse rotation of the ice outlet screw rod 20, so that an ice stirring structure is omitted, and the internal structure of the ice maker is simpler.

In practical application, the first preset number of turns is the same as the second preset number of turns, so that the ice cubes can return to the original positions after each inversion is finished, and the ice cubes are prevented from being accumulated towards the ice outlet or away from the ice outlet. For example, the first preset number of turns is not less than one turn and not more than two turns; and/or the second preset number of turns is not less than one turn and not more than two turns. If the first preset number of turns is less than one turn, the stirring effect is not obvious; if the first preset number of turns exceeds two turns, the ice cubes can move too long in the single forward or reverse rotation process, and the ice cubes are easy to move out of the ice outlet. Therefore, the first preset number of turns is set to be not less than one turn and not more than two turns, so that the stirring effect can be improved, the ice making error can be prevented, and the practicability of the control method of the ice making machine is improved. Similarly, if the second predetermined number of turns is less than one turn, the agitation effect is not significant; if the second preset number of turns exceeds two turns, the ice cubes can move too long in the single forward or reverse rotation process, and the ice cubes are easy to move out of the ice outlet. Therefore, the second preset number of turns is set to be not less than one turn and not more than two turns, so that the stirring effect can be improved, the ice making error can be prevented, and the practicability of the control method of the ice maker is improved.

The control method of the ice maker provided by the invention has the advantages that the ice outlet screw rod 20 is rotated forward for the preset number of turns and is rotated backward for the first number of turns after the first preset time, so that ice blocks can be effectively stirred, the ice blocks can be prevented from being conveyed to the ice outlet under the non-ice-taking working condition, the effective stirring of the ice blocks is realized, the adhesion of the ice blocks can be prevented, the ice outlet smoothness and stability are improved, the ice stirring structure is omitted, and the internal structure of the ice maker is simplified.

Specifically, the ice discharging screw 20 rotates forwards for a first preset number of turns, and rotates backwards for a second preset number of turns after the first preset time period to form a stirring sub-period;

the control method of the ice maker is provided with a plurality of sub-periods, and a second preset time interval is formed between every two adjacent stirring sub-periods.

In this embodiment, the ice discharging screw 20 repeatedly performs the sub-period of stirring at intervals of a second preset duration, so that the ice cubes can be stirred for a plurality of times to simulate the effect of shaking the ice cube storage barrel 10, and the stirring effect on the ice cubes can be improved by increasing the stirring times and the stirring frequency, thereby further preventing the ice cubes from being adhered.

Specifically, the first preset time period may be equal to the second preset time period, so that the time periods of the forward rotation interval and the reverse rotation interval are the same in the same stirring sub-period, and the stirring effect on the ice cubes is improved. For example, the first preset time is not less than 0.5 second and does not exceed 1 second; and/or the second preset time length is not less than 0.5 second and does not exceed 1 second. If the first preset time is less than 0.5 second, the interval time between forward rotation and reverse rotation is too short, the time for reversing and buffering the ice discharging screw rod 20 is too short, the reversing is too fast, the torsion load on the ice discharging screw rod 20 is increased, and the ice discharging screw rod 20 is easily damaged; if the first preset time exceeds 1 second, the stirring frequency is too small, and the effect of shaking the ice storage barrel 10 cannot be effectively simulated; therefore, setting the first preset time period to be not less than 0.5 seconds and not more than 1 second can protect the ice discharging screw 20 and improve the stirring effect of the ice cubes.

Similarly, if the second preset time is less than 0.5 second, the interval time between the forward rotation and the reverse rotation is too short, the time for reversing and buffering the ice discharging screw 20 is too short, and the reversing is too fast, so that the torque load on the ice discharging screw 20 is increased, and the ice discharging screw 20 is easily damaged; if the second preset time exceeds 1 second, the stirring frequency is too low, and the effect of shaking the ice storage barrel 10 cannot be effectively simulated; therefore, setting the second preset time period to be not less than 0.5 seconds and not more than 1 second can protect the ice discharging screw 20 and improve the stirring effect of the ice cubes.

In an embodiment, as shown in fig. 2, the method for controlling the ice maker further includes:

s3: acquiring the number of the stirrer sub-periods;

s4: and determining that the times of the sub-periods of the stirring are greater than or equal to preset times, and pausing for a third preset time, wherein the third preset time is greater than the second preset time.

In this embodiment, the sub-period of the stirring with the preset number of times is a main period of the stirring, and after each forward and reverse rotation of the ice discharging screw 20 with the preset number of times, the ice blocks near the ice discharging screw 20 are effectively separated, at this time, the ice discharging screw 20 can be suspended, so as to reduce energy consumption, reduce noise, and improve the service life of the ice discharging screw 20; after the third preset time, the stirring sub-period is continuously executed, so that the ice cubes in the ice outlet barrel can be intermittently stirred, ice can be discharged more smoothly, user experience can be improved, and energy consumption is reduced.

The third preset time is longer than the second preset time, so that the interval time between two adjacent stirring mother periods is enough. For example, the preset number is not less than 2 and not more than 4; and/or the third preset time length is not less than 140 seconds and not more than 160 seconds. If the preset times are less than 2, the stirring frequency is too low, and ice blocks cannot be effectively separated; if the preset times are more than 4, the time length of a stirring mother period is too long, user experience is influenced, and energy consumption is increased; therefore, the preset times are set to be not less than 2 times and not more than 4 times, so that the stirring effect of ice blocks can be improved, the energy consumption can be reduced, and the user experience is improved.

If the third preset time is less than 140 seconds, the intermittent time of the ice discharging screw 20 is too short, which is not beneficial to reducing energy consumption; if the third preset time is longer than 160 seconds, the ice blocks are excessively adhered and are not easy to separate by stirring, and the stirring difficulty is high; therefore, the third preset time is set to be not less than 140 seconds and not more than 160 seconds, so that the stirring difficulty of the ice cubes can be reduced, the stirring effect is improved, the energy consumption is reduced, and the practicability is improved.

In an embodiment, a predetermined number of the stirring sub-periods is used as a stirring main period, and before the step of starting the stirring main period, the method further includes:

s5: acquiring the motion state of the ice discharging screw rod 20;

s6: determining that the ice discharging screw 20 is in a static state, and starting the stirring mother period;

or determining that the ice discharging screw 20 is in a rotating ice conveying state, and suspending the stirring mother period.

In the present embodiment, before starting each stirring mother cycle, the system detects the motion state of the ice screw 20 and controls to execute or skip the stirring mother cycle according to the motion state of the ice screw 20. If the ice discharging screw 20 is in a static state, which indicates that the ice maker is not in an ice discharging state, the step of stirring the mother cycle is started, and the ice cubes are stirred to prevent the ice cubes from being stuck. If the ice discharging screw 20 is in the rotating ice feeding state, which indicates that the ice cubes are moving to discharge ice at this time, this process can replace the stirring mother cycle to reduce the adhesion of the ice cubes, and at this time, the stirring mother cycle can be skipped, i.e., the step of stirring the mother cycle can be suspended and executed again after a third preset time period. Therefore, the ice discharging process and the ice stirring process of the ice discharging screw 20 can be prevented from conflicting with each other, and the stability of the control method of the ice maker is improved.

In an embodiment, as shown in fig. 4, before the step of controlling the ice discharging screw 20 to rotate forward for a first preset number of turns, the method further includes:

s7: acquiring the amount of ice in the ice storage bin 10;

s8: determining that the ice amount is greater than or equal to a preset amount, and starting the step of controlling the ice discharging screw rod 20 to rotate forwards for a first preset number of turns;

s9: and stopping the step of controlling the ice outlet screw rod 20 to rotate forwards for the first preset number of turns when the ice amount is determined to be smaller than the preset amount.

In the present embodiment, after the ice making process is finished, if the ice cubes in the ice storage bin 10 are not taken, the ice cubes also need to be periodically stirred until the ice cubes in the ice storage bin 10 are not adhered enough to cause difficulty in ice discharging. Before stirring ice each time, the ice amount of the ice storage barrel 10 is detected, so that the ice discharging screw 20 can be prevented from idling, and the energy consumption is reduced. For example, when ice making is started, no ice cubes are present in the ice storage bin 10 or the amount of ice is small, and the ice discharging screw 20 may not enter the stirring cycle, so as to reduce energy consumption. When the ice amount reaches a preset value, the ice discharging screw 20 can normally start the next ice stirring period. After the ice making is finished, the evaporator stops working, and at this time, if a preset amount of ice still exists in the ice storage barrel 10, the ice discharging screw 20 should continue to perform an ice stirring cycle to prevent ice blocks from adhering until the amount of ice in the ice storage barrel 10 is less than the preset amount. Therefore, the ice discharging screw 20 can be prevented from idling when ice making is started, and stirring is stopped when the ice making is finished, so that the energy consumption is reduced, the ice discharging stability is improved, and the practicability of the ice making machine control method is improved.

In an embodiment, as shown in fig. 5, before the step of controlling the ice discharging screw 20 to rotate forward for a first preset number of turns, the method further includes:

s10: acquiring the motion state of the ice discharging screw rod 20;

s11: determining that the ice discharging screw rod 20 is in a static state, and starting to control the ice discharging screw rod 20 to rotate forwards for a first preset number of turns;

s12: and determining that the ice discharging screw rod 20 is in a rotating ice conveying state, and suspending the step of controlling the ice discharging screw rod 20 to rotate forward for a first preset number of turns.

In this embodiment, before controlling the ice discharging screw 20 to start each stirring step, the system detects the motion state of the ice discharging screw 20 and controls to perform or skip this stirring step according to the motion state of the ice discharging screw 20. If the ice discharging screw 20 is in a static state, which indicates that the ice maker is not in an ice discharging state, the ice stirring step of the ice discharging screw 20 is started, and the ice cubes are stirred to prevent the ice cubes from being stuck. If the ice discharging screw 20 is in the rotating ice feeding state, it indicates that the ice cubes are moving to discharge ice at this time, this process can replace the ice stirring step to reduce the adhesion of the ice cubes, at this time, the ice stirring step can be skipped, that is, the ice stirring step can be suspended, and the process is executed again after a preset time. Therefore, the ice discharging process and the ice stirring process of the ice discharging screw 20 can be prevented from conflicting with each other, and the stability of the control method of the ice maker is improved.

It should be noted that, if the user controls the ice discharging screw 20 to rotate and send ice during the ice stirring process, the ice stirring process is stopped and replaced by the ice discharging screw 20 rotating and sending ice process, so as to prevent the ice cubes from being stirred many times in a short time and reduce energy consumption.

The present invention also provides an ice making machine, comprising: the ice storage barrel comprises an ice storage barrel 10 and an ice outlet screw 20 arranged on the ice storage barrel 10, wherein the ice outlet screw 20 is used for conveying ice blocks to an ice outlet; and a memory, a processor and a computer program stored on the memory and executable on the processor, the computer program, when executed by the processor, implementing the steps of a method of controlling an ice maker. The specific steps of the control method of the ice maker refer to the above embodiments, and since the ice maker adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
