After the ice-removing process is completed, the ice-making machine can perform the water injection, ice-making and ice-removing processes of the next period, and the ice-making is repeated in such a circulating way. However, in the actual use process, the volume of ice blocks in the ice grids is too large due to excessive water amount in the ice grids caused by unstable water pressure, incomplete ice shedding in the previous period and the like, the ice blocks exceed the normal ice shedding range of the ice shedding rods, the ice shedding rods are clamped, and the ice shedding process fails. Or the ice-shedding rod is frozen, clamped and the like, so that the ice machine cannot smoothly shed ice. For example, in the working process of the ice maker, if the scraped ice blocks do not fall into the ice storage chamber smoothly, the ice blocks stay on the ice block baffle or are clamped in the ice block baffle clamping groove, so that the ice shedding rod cannot shed ice smoothly during next ice shedding, the ice shedding efficiency of the ice maker is affected, and even normal ice making is impossible.

Referring to fig. 2, the ice tray 1 includes an ice tray 11 and a shutter 12. The ice tray 1 may include a plurality of ice trays 11, and the plurality of ice trays 11 are arranged in an array. The ice tray 11 can be arc-shaped or crescent-shaped, so that ice can be conveniently scraped out of the ice tray 11 after ice making is finished, and the ice can be removed. The baffle 12 can include through-hole or breach 121, is favorable to the water injection in-process to the ice tray of ice tray, and water between the adjacent ice tray can flow, is favorable to keeping the higher comparatively close of surface of water between the different ice trays, thereby avoids the great partial ice tray ice-cube of part ice tray ice-cube to be less so that the inhomogeneous condition of ice-cube that makes, also is favorable to reducing because of the too big risk of blocking ice of ice-cube.

The deicing module 2 includes a deicing lever 21 and a motor 22. The deicing rod 21 is used for deicing the ice tray 11, and the motor 22 is used for driving the deicing rod 21. The motor 22 includes a position switch 221.

Referring to fig. 3, the refrigeration module 3 includes an evaporator 31, and the evaporator 31 is used for refrigeration. The evaporator 31 may have a U-shaped configuration to enhance the refrigerant transfer function.

Referring to fig. 1 and 3, the heating module 4 includes a heater 41 and a temperature sensor 42. The heater 41 is disposed near the ice tray 11 to melt ice, and is disposed near the evaporator 31 to defrost the evaporator 31. The temperature sensor 42 is arranged near the ice tray 11 and far away from the heater 41, so that the interference of the heater 41 on the temperature of the temperature sensor 42 can be avoided, the temperature value detected by the temperature sensor 42 is more close to the temperature of the ice tray and the temperature inside the ice tray, and the heating state or the refrigerating state of the ice tray and the heating state or the refrigerating state inside the ice tray can be accurately reflected.

The heater 41 may have a U-shaped structure and the ice tray 1 has a rectangular structure, the heater 41 is adapted to the size of the ice tray 1 and the heater 41 is stacked under the ice tray 1, so that the heater 41 can uniformly and efficiently heat the ice tray 1.

Referring to fig. 1 and 3, the evaporator 31 and the heater 41 may have sizes adapted to each other, and the evaporator 31 is stacked under the heater 41, so that the evaporator 31 may be defrosted while the ice tray 1 is heated by the heater 41, thereby improving ice making efficiency of re-making ice after the ice making machine 100 completes subsequent ice removal.

The controller 5 may be a microprocessor and is connected to the motor 22, the cooling module 3, and the heating module 4. The controller 5 is configured to execute the control method according to any one of the embodiments of the present application.

Next, a method for controlling an ice maker according to an embodiment of the present invention will be described.

It should be noted that the control method of the ice maker of the present application is applicable to the ice maker of any one of the embodiments of the present application and a modification thereof.

Referring to fig. 2 and 4, a method for controlling an ice maker 100 according to an embodiment of the present invention includes:

s01: and controlling the refrigeration module 3 to refrigerate the stored water in the ice tray 11 until the ice making ending condition is met.

S02: when the ice making end condition is satisfied, the heating module 4 is controlled to heat the ice tray 11 and the heating state of the heating module 4 is monitored.

S03: and when the heating state of the heating module 4 meets the deicing starting condition, controlling the deicing module 2 to perform deicing treatment on the ice tray 11.

Referring to fig. 2 and 5, in some embodiments, the control method may further include step S5, step S06, and step S07.

S05: monitoring the deicing state of the deicing module 2 in the process of controlling the deicing module 2 to perform deicing treatment on the ice tray 11;

s06: when the deicing state is deicing failure, controlling the heating module 4 to heat the ice tray 11 and monitoring the heating state of the heating module 4;

s07: and when the heating state of the heating module 4 meets the ice-melting completion condition, controlling the heating module 4 to stop heating.

In a further embodiment, please refer to fig. 6, after ice making is started, the control method first controls the refrigeration module 3 to refrigerate the stored water in the ice tray 11 until an ice making ending condition is met, so that ice making is ended. After the ice making is finished, that is, when the ice making finishing condition is satisfied, for example, when the ice making time period reaches the fifth preset time period t5, the heating module 4 is controlled to start heating the ice tray 11 and the heating state of the heating module 4 is monitored. In some embodiments, the ice-making end condition needs to be further satisfied that the ice of the ice bank is not full, whereby the ice of the ice bank can be prevented from overflowing or being inconveniently taken out. The heating state of the heating module 4 includes a heating time period and a heating temperature. When the heating state of the heating module 4 meets the ice-shedding opening condition, that is, the heating time reaches a third preset time t3 or the heating temperature reaches a second preset temperature Tb, the ice-shedding module 2 is controlled to perform ice-shedding treatment on the ice tray 11. In the process of controlling the deicing module 2 to perform deicing treatment on the ice tray 11, the heating module 4 is controlled to continue heating to perform defrosting treatment on the refrigerating module 3 until the heating state of the heating module 4 meets the defrosting ending condition. The defrosting end condition includes that the heating time length reaches a fourth preset time length t4 and the heating temperature reaches a third preset temperature Tc, and the third preset temperature Tc is greater than the second preset temperature Tb. In addition, when the ice tray 11 is continuously heated during the process of performing the deicing process on the ice tray 11, the deicing efficiency of the deicing process on the ice tray 11 can be further increased, and the ice removing rod 21 is prevented from being frozen during the deicing process.

Preferably, the second preset temperature Tb may be less than or equal to zero degrees centigrade, for example the second preset temperature Tb may be-5 ℃, -4 ℃, -3 ℃, -2 ℃, -1 ℃ or 0 ℃ and the like. The third predetermined temperature Tc may be greater than zero degrees centigrade, for example, the third predetermined temperature Tc may be 3 ℃, 4 ℃, 4.5 ℃, 5 ℃, 5.5 ℃, 6 ℃ or 6.5 ℃, etc. Heating module 4 heats ice tray 11, and when temperature sensor 42 temperature reached the second and predetermine temperature Tb, control deicing module 2 promptly and carry out the deicing processing to ice tray 11, the second is predetermine temperature Tb and be less than or equal to zero degree centigrade for deicing module 2 begins to carry out the deicing processing when the ice in ice tray 11 is about to begin to melt, and follow-up continuation heating continues the deicing processing simultaneously, thereby can improve deicing efficiency.

Preferably, the third preset time period t3 is the preset heating upper limit time tmax of the heater 41, which can avoid the heating time from being too long due to the failure of the temperature sensor 42 or other transmission failures. The upper heating limit time tmax may include 9min, 10min, 11mim, 12min, or 13min, etc. And after the defrosting process is started, the heating time of the heater 41 is counted again, and when the heating time of the heater 41 reaches tmax again and the heating temperature does not reach the third preset temperature Tc, the heater 41 is also controlled to stop working, and the next deicing operation is continued. The fourth preset time t4 is the minimum defrosting time, and the minimum defrosting time may be 5min, 5.5min, 6min, 6.5min, 7min, or the like. That is, it is ensured that the defrosting of the evaporator 31 is completed after the fourth preset time period t 4. It will be appreciated that if the ice cubes may have completely separated from the ice grid 11 when the heating module 4 is controlled to continue heating for defrosting the cooling module 3, the heater 41 heats the ice grid 11 and the temperature rises faster, but the evaporator 31 still takes some time to ensure defrosting is completed. Therefore, setting the fourth preset time period t4 as the minimum defrosting time is beneficial to the evaporator 31 to defrost smoothly, so as to better improve the ice making efficiency of re-making ice after the ice maker 100 finishes the subsequent ice removal.

With continuing reference to fig. 6, during the ice removing process of the ice tray 11 by the ice removing module 2, after the defrosting process, the ice removing state of the ice removing module 2 is monitored. When the deicing state is deicing failure, performing deicing treatment, namely controlling the heater 41 in the heating module 4 to heat the ice tray 11 and monitoring the heating state of the heating module 4, and controlling the heating module 4 to stop heating when the heating state of the heating module 4 meets the deicing completion condition. The ice-melting completion condition may be that the heating time length reaches a second preset time length t2 or the heating temperature reaches a first preset temperature Ta. The second preset time period t2 may be a preset heating upper limit time tmax of the heater 41, which may avoid too long heating time caused by a failure of the temperature sensor 42 or other transmission failures. The first predetermined temperature Ta may be greater than the third predetermined temperature Tc, for example, the first predetermined temperature Ta may be 8 ℃, 8.5 ℃, 9 ℃, 9.5 ℃, 10 ℃, 10.5 ℃, 11 ℃, 11.5 ℃ or 12 ℃ or the like. Because the third preset temperature Tc is stable for the heating of the deicing module 2 when the deicing module is used for normally deicing the ice tray 11, the first preset temperature Ta is greater than the third preset temperature Tc, so that the ice tray 11 is heated at the preset heating temperature higher than the normal deicing treatment when the deicing fails, and the ice bar which may be clamped with the deicing bar 21 or clamped in the ice tray 11 can be rapidly melted, thereby improving the efficiency of deicing and continuously completing subsequent deicing when the deicing fails, and being beneficial to improving the ice production efficiency of the ice maker 100.

Referring to fig. 2, 5 and 7, in some embodiments, the deicing module 2 includes a motor 22. The monitoring of the deicing state of the deicing module 2 (S05) includes:

s051: after the motor 22 is started, timing the starting time of the motor;

s052: detecting whether the motor 22 returns to the initial position within a time period from the start of the motor start time period to the first preset time period t 1;

s053: when the motor 22 returns to the initial position within the time period from the start of the motor starting time to the first preset time t1, judging that the ice-shedding state is successful in ice shedding;

s054: and when the motor 22 does not return to the initial position within the time period from the start of the motor starting time period to the first preset time period t1, judging that the ice shedding state is ice shedding failure.

Referring to fig. 2 and 8, in some embodiments, the control method may further include:

s08: when the deicing state is judged to be successful, resetting the deicing failure times;

s09: when the deicing state is judged to be deicing failure, increasing the deicing failure times once, and setting a water non-injection flag bit;

s010: and when the deicing module 2 meets the deicing restart condition, controlling the deicing module 2 to reinitialize and then perform deicing treatment on the ice tray 11, wherein the deicing restart condition comprises that the deicing failure times are greater than the preset times.

Specifically, referring to fig. 9, after ice shedding is started, the motor 22 is started, and the start time of the motor 22 is counted. Then, it is detected whether the motor 22 is returned to the initial position within a period of time in which the starting period of the motor 22 is started until the first preset period t1 is reached. When the motor 22 returns to the initial position within the time period from the start time of the motor 22 to the first preset time t1, the ice-shedding state is judged to be the ice-shedding success, the ice-shedding failure times are cleared, and the next water injection and ice making process can be skipped. The first preset time period t1 may be 11min, 12min, 13min, 14min or 15min, and may be 2 to 4 times the time period from the motor start to return to the initial position in normal deicing, i.e., in the case where no ice scraping failure occurs. For example, if it takes 4min on average for the motor to start until returning to the initial position in case of normal deicing, the first preset time period t1 may be 10 min. When the motor 22 does not return to the initial position within the time period from the start of the motor 22 until the first preset time period t1, it is determined that the ice shedding state is ice shedding failure. The number of times of ice-shedding failure is increased once, and a water non-injection flag bit is set. The water non-injection flag bit is set, so that water injection is not performed in the next water injection ice making process, and ice making and ice removing are performed directly. It can be understood that when the ice-shedding state is ice-shedding failure, the ice-melting process can be executed, and because the temperature in the ice-melting process can reach the first preset temperature Ta and is relatively high, more ice-melting water can be generated in the ice tray 11, and if the next water injection ice making and ice-shedding process is normally performed, the water storage amount in the ice tray 11 is too much, so that the phenomenon that the ice is overflowed or the made ice blocks are too large and are easily blocked again is caused. Therefore, the ice-shedding state is judged to be ice-shedding failure, the water-non-injection flag bit is set, water in the ice grid 11 can be prevented from falling into the ice storage chamber, the situation that the ice-shedding rod 21 is clamped in the next round of ice shedding can be reduced, the ice-making quality can be improved, the failure rate of the ice-making machine 100 is reduced, and the ice-making efficiency is improved. And when the deicing module 2 meets the deicing restart condition, namely the deicing failure times are greater than the preset times N, controlling the deicing module 2 to reinitialize and then deicing the ice tray 11, wherein the deicing restart condition comprises that the deicing failure times are greater than the preset times N. For example, N may be 3, and when the number of times of ice shedding failure is greater than the predetermined number of times 3, it is determined that the ice shedding module 2 is failed, and the ice shedding module 2 is controlled to be initialized. In some embodiments, the software process of the ice-shedding module 2 is mainly installed on the motor 22, and when the ice-shedding failure time is greater than the predetermined time 3, it may be determined that the motor 22 is out of order and the motor 22 is controlled to be initialized. It can be understood that when the number of times of ice detachment failure is greater than a certain number of times, since the ice detachment process is mainly realized by the ice detachment module 2, the ice detachment module 2 is likely to have a fault, and the initialization of the ice detachment module 2 is controlled at the moment, so that the ice detachment failure caused by the internal fault problem of the ice detachment module 2 can be avoided, and the ice making efficiency can be improved.

In summary, according to the control method of the ice maker, the ice maker and the refrigerator in the embodiments of the present application, the heating module is controlled to continue heating to defrost the refrigeration module while the deicing module is controlled to perform deicing on the ice tray, so that defrosting on the evaporator is performed while heating and deicing are performed without increasing hardware, and accordingly, the ice making efficiency of re-making ice after subsequent deicing of the ice maker is completed can be improved. And, control heating module continued heating when this application carries out the process of deicing processing to the ice tray, still keeps the heating to the ice tray in other words, can further accelerate the efficiency of deicing that carries out deicing processing to the ice tray to be favorable to preventing the in-process deicing pole of deicing from being frozen.
