Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a refrigerator 100 includes a cabinet and a door 105 for opening and closing the cabinet, and an ice making compartment may be disposed on the door 105 of the refrigerator 100, and an ice making assembly may be installed in the ice making compartment. Of course, the ice making compartment may be provided in the refrigerating compartment or the freezing compartment of the cabinet, or the ice making unit may be directly installed inside the freezing compartment.
The ice making assembly may include an ice making tray 107, a water supply device supplying liquid water into the ice making tray 107, and an ice storage bin for receiving ice made by the ice making tray 107. The door 105 of the refrigerator 100 may further be provided with a dispenser 106 for dispensing ice or water, and a user may take out ice stored in the ice bank or water supplied from the water supply device directly through the dispenser 106 without opening the door 105. The ice making assembly can perform ice removal by twisting the ice tray and also can perform ice removal by the ice raking mechanism.
Referring to fig. 2, a temperature sensor 108 and a heater 109 may be installed at the bottom of the ice-making tray 107. Of course, the temperature sensor 108 and the heater 109 may be installed above the ice-making tray 107, such as an ice-making tray cover provided on the ice-making tray 107, and the temperature sensor 108 or the heater 109 may be provided on the ice-making tray cover.
The heater 109 may be used to heat the ice-making tray 107, for example, the heater 109 on one side of the ice-making tray 107 may be activated during freezing of liquid water, so that the liquid water in the ice-making tray 107 is gradually frozen from the side where the heater 109 is not installed to the side where the heater 109 is installed, and bubbles in the water are driven to the side where the heater 109 is installed, to make transparent ice. The heater 109 at the bottom of the ice-making tray 107 may also be activated after the liquid water in the ice-making tray 107 is completely condensed to facilitate separation of ice pieces from the ice-making tray 107 to assist in ice shedding.
The temperature sensor 108 may be configured to detect a temperature of the tray of the ice-making tray 107, determine a frozen state of water in the ice-making tray 107 according to the tray temperature, and control an operation of the heater 109 according to the tray temperature detected by the temperature sensor 108. When the temperature of the ice tray is-8 ℃, for example, it may be determined that the liquid water in the ice-making tray 107 tends to be in a completely frozen state, the heater 109 may be controlled to be turned off, and the heater 109 may be controlled to be turned on again after a predetermined period of time to assist in ice shedding.
Referring to fig. 3, in order to improve transparency of ice, an embodiment of the present invention provides an ice making control method, including:
acquiring the tray temperature of the ice-making tray 107;
the heating power of the ice making heater 109 is controlled such that the staying time in each preset temperature drop zone is within a preset time range, wherein the preset temperature drop zones are at least two temperature drop zones in which the ice making tray 107 is equally divided by a temperature difference between the freezing point temperature and the freezing temperature.
In the present embodiment, the tray temperature of the ice-making tray 107 may be detected by a temperature sensor 108 installed at the bottom of the ice-making tray 107. The freezing temperature is 0 deg.c, and when the temperature of the ice tray is lowered to the freezing temperature, the liquid water in the ice-making tray 107 starts to gradually freeze. When the temperature of the ice tray is lowered to the freezing temperature, the liquid water in the ice-making tray 107 may be substantially completely frozen, the freezing temperature being about-8 ℃.
In order to improve the transparency of ice, the temperature of the ice tray between the freezing point temperature and the freezing temperature may be divided into at least two preset temperature reduction sections by a certain temperature difference, and the power of the heater 109 may be controlled during the ice making process such that the staying time in each preset temperature reduction section is within a preset range.
Thus, the liquid water in the ice-making tray 107 can be ensured to be frozen from one side to the other side at a relatively uniform speed, and the ice transparency is prevented from being nonuniform due to excessively high or low freezing speed.
In a specific embodiment, the ice-making tray 107 is divided into a plurality of preset temperature reduction sections between the freezing temperature and the freezing temperature by taking 1 ℃ as a temperature difference, and the retention time in each preset temperature reduction section is 45-55 minutes.
If the freezing temperature of the ice making tray 107 is-8 ℃, the temperature from-8 ℃ to 0 ℃ can be divided into 8 preset temperature reduction intervals, specifically, the temperature is from-1 ℃ to 0 ℃, from-2 ℃ to-3 ℃ and the like. The residence time in each preset cooling interval, i.e. the time required to reduce each degree celsius, is in the range of 45-55 minutes to produce ice with the best transparency.
Further, referring to fig. 4, in an embodiment of the present invention, the ice making control method further includes:
and controlling the heater 109 to operate at a preset power corresponding to the current preset cooling interval.
In the embodiment, the temperature in the ice making chamber can be stabilized at about-18 ℃ to-20 ℃, and in order to ensure the stable proceeding of the ice making process and avoid the influence of the error operation of the user on the ice making process and the ice making transparency caused by the temperature adjustment of the ice making chamber, the ice making chamber can be set to be in a temperature unadjustable mode in the ice making process.
Therefore, the preset power of the heater 109 corresponding to each preset cooling interval may be stored in the database of the refrigerator 100, and in the case that the temperature of the ice making compartment is relatively stable, the corresponding preset power may be used for each preset cooling interval, so that the retention time in each preset cooling interval may be within a preset range.
The preset power may be a power set when the refrigerator 100 leaves the factory. In addition, because the usage environments of the refrigerator 100 are different, the power set when the refrigerator 100 leaves the factory during the ice making process may cause deviation of the retention time in each preset cooling interval, which may be slightly smaller than the preset range or slightly larger than the preset range, and thus the optimal usage state cannot be achieved. Therefore, the preset power corresponding to each preset cooling interval may be the power stored in the database after being automatically adjusted on the basis of the power set in the factory.
Specifically, for example, when the preset temperature reduction interval is set to-1 ℃ to 0 ℃ in the database at the time of factory shipment, the power of the corresponding heater 109 is 6W. When the ice is made for the first time, the heater 109 can be operated at 6W within the range of-1 ℃ to 0 ℃, the residence time within the range of-1 ℃ to 0 ℃ is recorded, and if the residence time is within 45 minutes to 55 minutes, the 6W is set as the preset power of the heater 109 corresponding to the temperature of-1 ℃ to 0 ℃. If the residence time in the temperature range of-1 ℃ to 0 ℃ is less than 45 minutes, the corresponding preset power can be increased when the ice is made next time, for example, the heating wire is operated at 6.1W, and the residence time in the temperature range of-1 ℃ to 0 ℃ is recorded; on the contrary, if the residence time in the range of-1 ℃ to 0 ℃ is more than 55 minutes, the corresponding preset power may be reduced at the time of the next ice making, for example, the heater 109 is operated at 5.9W until the residence time in the range of-1 ℃ to 0 ℃ is adjusted to be in the range of 45 minutes to 55 minutes, and the power of the corresponding heater 109 is stored as the preset power corresponding to the range of-1 ℃ to 0 ℃.
So, all set up the power of corresponding heater 109 to every cooling interval of predetermineeing, make the ice in-process with corresponding power operation heater 109, can guarantee that liquid water freezes speed evenly, can simplify the inside procedure simultaneously, improve the operating efficiency.
Further, in an embodiment of the present invention, the preset power corresponding to each preset cooling interval is reduced along with the temperature reduction of the preset cooling interval.
In this embodiment, in the ice making process, along with the decrease of the temperature of the ice tray, the liquid water in the ice making tray 107 is gradually condensed into ice, that is, the ice layer in the ice making tray 107 is thicker and thinner, and the liquid water is less and less, so as to ensure the stable freezing speed of the water in the ice making tray 107, the heat required by the ice making tray 107 is also gradually reduced, and therefore, the preset power corresponding to each preset temperature reduction interval is different, and the preset power corresponding to each preset temperature interval is reduced along with the decrease of the temperature of the preset temperature reduction interval.
Further, in an embodiment of the present invention, the ice making control method further includes:
when the cooling speed in each preset cooling interval is less than a first preset speed, controlling to reduce the power of the heater 109;
and when the cooling speed in each preset cooling interval is greater than a second preset speed, controlling to increase the power of the heater 109.
In this embodiment, when the temperature of the ice tray is decreased to each preset cooling interval during the ice making process, the ice tray may be operated at the power corresponding to the preset cooling interval stored in the database, and the cooling speed in the temperature interval may be continuously monitored and calculated. If the cooling rate in the preset cooling interval is less than the first preset rate, it may be determined that the ice tray temperature is decreased slowly, and the heating power of the heater 109 is high, so that the heater 109 is continuously operated with the power, which may result in the staying time in the preset cooling interval being longer than the preset range, and at this time, the power of the heater 109 may be controlled to be decreased to shorten the staying time in the preset cooling interval.
On the contrary, if the cooling rate in the preset cooling interval is greater than the first preset rate, it may be determined that the temperature of the ice tray is decreased too fast, the heating power of the heater 109 is low, and if the heater 109 is continuously operated with the power, the staying time in the preset cooling interval may be smaller than the preset range, so that the power of the heater 109 may be controlled to be increased to slow down the cooling rate, and the staying time in the preset cooling interval may be prolonged.
Specifically, for example, when the freezing temperature is-8 ℃, the freezing temperature and the freezing temperature can be divided into 8 preset temperature reduction sections by taking 1 ℃ as a temperature difference. If the heating power of the corresponding heater 109 is 6W at 0-1 ℃, and the speed of reducing the temperature from 0 ℃ to-0.5 ℃ is too fast in the heating process, it can be determined that the heating power of the heater 109 is too low, and the ice making tray 107 needs more heat to slow down the temperature reduction speed, otherwise, the retention time in the preset temperature reduction interval is too short, and therefore, the heating power of the heater 109 can be increased. On the contrary, if the speed of lowering from 0 ℃ to-0.5 ℃ is too slow during the heating process, it may be determined that the heating power of the heater 109 is too high and the amount of heat transferred from the heater 109 to the ice tray 107 is too large, and if the heater 109 continues to operate at power, the retention time in the cooling interval of 0 — -1 ℃ may be too long, and thus the heating power of the heater 109 may be reduced.
Therefore, the power of the heater 109 is dynamically adjusted in real time according to the temperature of the ice tray in the ice making process, the condition that the stay time in the preset cooling interval is not in the preset range due to the influence of external factors can be avoided, and the ice with high transparency can be made.
Further, in an embodiment of the present invention, the ice making control method further includes:
controlling to increase power of the heater 109 when the cooling capacity supplied into the ice making compartment increases;
when the cooling capacity supplied into the ice making compartment is decreased, the power of the heater 109 is controlled to be decreased.
In the present embodiment, in order to maintain the temperature in the ice making compartment within a certain temperature range, the amount of cold supplied to the ice making compartment needs to be adjusted during the ice making process, so as to avoid the temperature in the ice making compartment from being too low due to the continuous supply of a large amount of cold air to the ice making compartment. Specifically, the amount of cold supplied into the ice making compartment may be adjusted by adjusting the operation of a refrigeration system of the ice making compartment, or the size of a damper of the ice making compartment.
When the amount of cooling energy supplied to the ice making compartment increases, the cooling rate in the ice making compartment increases, and at this time, in order to maintain the residence time of the ice tray temperature in the preset cooling interval within the preset range, the power of the heater 109 needs to be increased, that is, the heat output by the heater 109 needs to be increased, so as to prevent the ice tray temperature from decreasing too fast. Similarly, when the amount of cooling energy supplied to the ice making compartment is decreased, the cooling rate in the ice making compartment is decreased, and in order to maintain the stay time of the ice tray temperature in the preset cooling interval within the preset range, the power of the heater 109, that is, the amount of heat output from the heater 109, needs to be decreased to avoid the ice tray temperature from being decreased slowly.
Therefore, the power of the heater 109 is automatically adjusted according to the cold energy supplied to the ice making compartment, the stability of the cooling speed of the ice making tray 107 can be further improved, and the cooling time in each preset cooling interval is ensured to be within a preset range, so that ice with better transparency can be prepared.
Further, in an embodiment of the present invention, an ice making control method includes:
when the compressor is turned off, the power of the heater 109 is controlled to be reduced by one half.
In this embodiment, during the operation of the refrigeration system, the compressor may be operated at predetermined time intervals to maintain the temperature within the ice making compartment within a predetermined temperature range. When the compressor is turned off, the refrigeration system does not supply cold air to the ice making compartment any more, and at this time, in order to keep the staying time of the ice making tray 107 in the preset cooling interval within the preset range, the power of the heater 109 needs to be reduced. That is, when the cooling capacity in the ice making compartment is decreased, the heating capacity of the heater 109 may be decreased, and the temperature of the ice making tray 107 may be prevented from being decreased too slowly and staying for too long time in the predetermined temperature decreasing section while the compressor is turned off.
In a specific embodiment, when the compressor is turned off, the power of the heater 109 may be reduced by one half to ensure that the cooling speed of the ice tray 107 is stable, and the retention time in the preset cooling interval does not exceed the preset range, so as to make ice with high transparency.
Further, in an embodiment of the present invention, the ice making control method further includes:
when the ice tray temperature is higher than the preheating temperature, controlling the heater 109 to be turned off;
when the temperature of the ice tray is lowered to the preheating temperature, the heater 109 is controlled to be activated with preheating power, and the power of the heater 109 is controlled to be increased at a preheating speed.
In the present embodiment, the preheating temperature is 0 ℃ higher than the freezing temperature, and specifically, the preheating temperature may be 2 ℃. When the temperature of the ice tray is lowered to 0 ℃, the liquid water in the ice-making tray 107 begins to freeze gradually, and at this time, the ice-making heater 109 needs to be turned on to cause the water in the ice-making tray 107 to freeze from one side of the ice-making tray 107 to the other side. In order to further ensure that the water in the ice tray 107 is frozen from one side and simultaneously avoid the temperature jump from affecting the transparency of the ice, it is necessary to start preheating the ice tray 107 before the temperature of the ice tray is reduced to 0 ℃, and uniformly increase the power of the heater 109 to the preset power corresponding to the first preset temperature reduction interval. The preheating power of the heater 109 may be selected to be small and may be between 0-0.5W.
Therefore, the heater 109 is started to preset the ice-making tray 107 before the liquid water is frozen, and the ice-making effect is prevented from being influenced by sudden temperature change. Meanwhile, the phenomenon that the heater 109 is started when the temperature reaches 0 ℃ to cause uneven temperature output and influence the retention time in the first preset cooling interval can be avoided, or the side, where the heater 109 is installed, of the ice making tray 107 is frozen due to untimely heating.
Further, in an embodiment of the present invention, the ice making control method further includes:
when the ice tray temperature is lowered to the freezing temperature, the heater 109 power is controlled to be lowered to 0 at the freezing speed.
In the present embodiment, when the temperature of the ice tray is lowered to the freezing temperature, the liquid water in the ice-making tray 107 is substantially in a completely frozen state, and the heater 109 may be turned off. However, there may be water that is not completely frozen on the side of the ice tray 107 where the heater 109 is installed, and in order to avoid the influence of the sudden temperature change on the ice cubes, the heater 109 may be turned off in a manner of gradually reducing the power of the heater 109.
The freezing speed may be a factory-set speed, that is, when the temperature of the ice tray is lowered to the freezing temperature, the power of the heater 109 is initially controlled to gradually decrease at the freezing speed. Specifically, for example, if the freezing temperature is-8 ℃, the power of the heater 109 may be started to be reduced when the temperature sensor 108 detects that the temperature of the ice tray is-8 ℃, for example, the power of the heater 109 may be reduced to 0 within 30 minutes.

An ice-making assembly for making ice can be mounted on a cabinet or a door of refrigerator 100, and refrigerator 100 further includes a memory 102 and a processor 101, and memory 102 and processor 101 are communicatively connected through a communication bus 104.
