The control module 20 controls the process of ice making and ice removing as follows: the water injection control module 19 injects water into the ice tray 12 through the water injection port 15, and controls the refrigeration module 18 to refrigerate so that the water is frozen into ice blocks; the ice tray temperature sensor 16 is used for detecting the temperature of the ice tray 12 and determining whether ice making is finished; after ice making is finished, the ice tray 12 is heated by controlling the deicing heater 17, so that the part of the ice block, which is in contact with the ice tray 12, is melted, and deicing is facilitated; the deicing grid 13 is fixed on the deicing rod 14, the deicing grid 13 rotates along with the rotation of the deicing rod 14 when the deicing rod 14 rotates, and the control motor 11 drives the deicing grid 13 to scrape ice blocks in the ice grids 12 out of the ice grids when driving the deicing rod 14 to rotate in the forward direction, so that the ice grids 12 are deiced.
Examples 1,
Specifically, as shown in fig. 4, the control module 20 is configured to execute the following control method of the ice maker:
s101, injecting water into the ice tray 12.
The control module 20 controls the water injection module 19 to inject water into the ice tray 12 through the water injection port 15.
And S102, refrigerating the ice tray 12 to execute an ice making process.
The control module 20 controls the refrigeration module 18 to refrigerate the ice tray 12, so that the water is frozen into ice blocks, and an ice making process is performed.
And S103, if the temperature of the ice tray 12 is less than or equal to the first set value after the first preset time, stopping refrigerating the ice tray 12.
And S104, controlling the heating of the deicing heater 17 and the forward rotation of the deicing rod 14 according to the temperature of the ice tray 12 to execute a first deicing process.
Specifically, as shown in fig. 5, the control module 20 is configured to execute steps S1041 to S1042:
and S1041, controlling the deicing heater 17 to heat the ice tray.
After the ice making is finished, the control module 20 controls the refrigeration module 18 to stop refrigerating the ice tray 12, and controls the deicing heater 17 to heat the ice tray 12 for a certain time, so that the part of the ice block, which is in contact with the ice tray 12, is melted, and the ice is conveniently deiced.
And S1042, if the temperature of the ice tray is greater than or equal to the second set value, controlling the deicing heater 17 to stop heating, and controlling the deicing rod 14 to rotate in the forward direction to execute the first deicing process.
Wherein the first set value is smaller than the second set value.
The control module 20 controls the motor 11 to drive the deicing rod 14 to rotate in the forward direction, and drives the deicing grid 13 to deice the ice grids 12.
And S105, if the deicing rod 14 cannot rotate forwards to the preset position after the second preset time, controlling the deicing rod 14 to rotate backwards to the preset position.
It is explained that the ice cubes made this time are too large due to the excessive water injection amount or incomplete ice removal at the previous time, the ice removing lever 14 cannot rotate forward to remove ice due to being stuck, and is returned to the preset position. Therefore, the control module 20 controls the motor 11 to rotate the ice-shedding bar 14 in the reverse direction to a predetermined position, so that the contact area between the ice cubes and the ice grid 12 is as large as possible.
And S106, controlling the heating of the deicing heater 17 and the forward rotation of the deicing rod 14 according to the temperature of the ice tray 12 to execute a second deicing process.
Namely, when the first deicing process fails, a second deicing process is tried, wherein the first deicing process is a normal deicing process, and the second deicing process is a treatment process of a fault caused by excessive water injection. It is understood that the second deicing process may be performed a plurality of times until deicing is successful.
Specifically, as shown in fig. 6, the control module 20 is configured to execute steps S1061-S1062:
and S1061, controlling the deicing heater 17 to heat the ice tray 12.
And S1062, if the heating time reaches a third preset time or if the temperature of the ice tray 12 is greater than or equal to a third set value, controlling the deicing heater 17 to stop heating, and controlling the deicing rod 14 to rotate in the forward direction to perform a second deicing process.
As shown in fig. 7, the control module 20 is further configured to execute S107:
and S107, if the second deicing process is continuously executed for N times, stopping filling water into the ice tray 12, and repeatedly executing the ice making process and the first deicing process.
In the process of deicing through heating, part of water remains in the ice grids, and if ice is made according to the normal water injection process after continuous N times of deicing failure, the fault of excessive water injection must be repeated. Therefore, a fault accumulation mechanism is introduced, after the second deicing process is performed N times in succession, the ice maker does not fill water, but freezes the residual water into ice by the ice making and deicing processes again, and then releases the ice by the deicing rod 14, and the normal water filling ice making can not be performed once or for multiple times until certain conditions are met (for example, the deicing is successful N times in succession), so that the reliability of the ice making and deicing processes is ensured.
N is a positive integer, for example N may be 2.
According to the ice maker and the control method of the ice maker, when the ice removing rod cannot rotate forwards to the preset position due to being clamped, the ice removing rod is controlled to rotate reversely to the preset position, and the ice removing process is carried out again, so that the ice maker can be prevented from being clamped on the ice removing rod in the ice removing process, and the ice removing process is prevented from failing.
Examples 2,
As shown in fig. 8, the control module 20 can be used to perform the following ice maker control method: wherein steps S201-S204 are an ice making process, steps S205-S209 are a normal deicing process,
s201, clearing the fault mark.
The fault flag is used to identify the number of times the second deicing process is performed. The second deicing process is described above and will not be repeated here.
S202, injecting water into the ice tray 12.
This step is the same as S101 and is not repeated here.
S203, the first timer T1 is cleared and starts counting time.
The first timer T1 is used to count the cooling time.
And S204, refrigerating the ice tray 12 to execute an ice making process.
This step is the same as S102 and is not repeated here.
And S205, if the timing of the first timer T1 reaches a first preset time P1 (namely after the first preset time), and the temperature TEMP of the ice tray 12 is less than or equal to a first set value S1, stopping cooling the ice tray 12.
This step is the same as S103.
And S206, controlling the deicing heater 17 to heat the ice tray 12.
This step is the same as S1041 and is not repeated here.
And S207, if the temperature TEMP of the ice tray 12 is greater than or equal to the second set value S2, controlling the deicing heater 17 to stop heating, and clearing and starting the second timer T2.
The second timer T2 is used to count the rotation time of the ice shedding lever 14.
And S208, controlling the ice removing rod 14 to rotate forwards.
Steps S207 and S208 are the same as step S1042 and are not repeated here.
S209, if the counted time of the second timer T2 does not reach the second preset time P2 (i.e., within the second preset time), and the deicing lever 14 can rotate forward to the preset position, the fault flag is decremented by 1.
Step S201 is performed if the failure flag is less than or equal to 0, otherwise step S203 is performed, which is the same as step S107.
S210, if the timing of the second timer T2 reaches a second preset time P2 (namely after the second preset time), and the deicing lever 14 cannot rotate forward to the preset position, controlling the deicing lever 14 to rotate reversely to the preset position, adding 1 to the fault flag, clearing the third timer T3 and starting timing.
The third timer T3 is used to count the heating time of the deicing heater 17.
This step is the same as step S105 and is not repeated here.
And S211, controlling the deicing heater 17 to heat the ice tray 12.
If the third timer T3 counts a third preset time P3 (i.e., the heating time reaches the third preset time), or if the temperature TEMP of the ice tray 12 is greater than or equal to a third set value S3, step S207 is executed again (i.e., the deicing heater 17 is controlled to stop heating, and the deicing lever 14 is controlled to rotate in the forward direction).
