Generally, an ice making device includes an ice making tray, an ice bank, a full ice detection mechanism, and a controller. The ice making tray is used for making ice cubes, the ice storage box is used for storing the ice cubes discharged by the ice making tray, and the ice full detection mechanism is used for detecting whether the ice cubes in the ice storage box reach a full ice judgment reference value. When the ice blocks in the ice storage box reach the full ice judgment reference value, the controller controls the ice making tray to stop making ice.
As shown in fig. 1 to 5, an embodiment of the present invention discloses a method for controlling an ice making device. As shown in fig. 1, the method includes:
and S11, calculating the average ice-taking time interval and the average ice-taking amount in the preset time.
Specifically, the preset time may be set to 1 week or 1 month, and the average ice-fetching time interval and the average ice-fetching amount for the user to fetch ice are calculated during the preset time. The ice-taking time interval refers to the time length of the user between two adjacent ice-taking processes, and the average ice-taking time interval is the average value of the time lengths of the user between two adjacent ice-taking processes; the ice-picking amount refers to the weight of ice picked up by a user each time the ice is picked up, and the average ice-picking amount is the average value of the weights of ice picked up by the user each time the ice is picked up.
And S12, determining a first reference value according to the average ice-taking amount.
Specifically, the first reference value is set as the average ice picking amount plus a redundancy amount, and the redundancy amount is set according to experiments or experience, and generally speaking, the redundancy amount is set to be between 5% and 20% of the average ice picking amount.
Generally, the amount of ice used by a user at a time is maintained at a value that is not very different, and therefore, if the amount of ice stored in the ice bank is maintained at an average ice-picking amount level, the ice-using requirement of the user in most cases can be satisfied. However, the user may occasionally take ice larger than the average amount of ice taken, and therefore, the first reference value is set to the average amount of ice taken plus the redundancy amount in order to satisfy the situation that the user takes ice more than the average amount of ice taken at a certain time.
S13, it is determined whether the first reference value is less than the ice bank capacity.
Generally, in the related art, the ice bank capacity is set to the full ice determination reference value. As can be seen from the above, the first reference value is the sum of the average ice-fetching amount and the redundancy amount, and thus the first reference value is likely to be larger than the capacity of the ice bank. When the first reference value is greater than the capacity of the ice bank, setting the first reference value as the full ice determination reference value at this time may cause a problem of overflowing of ice cubes within the ice bank. When the first reference value is smaller than the ice bank capacity, it indicates that the amount of ice taken by the user each time is small, that is, a smaller value may be set as the full ice determination reference value. Therefore, it is first necessary to judge the magnitude relation of the first reference value and the ice bank capacity to determine the subsequent step with the judgment result. Specifically, the method comprises the following steps: if the first reference value is smaller than the ice bank capacity, step S14 is executed to determine whether the average ice-fetching time interval is greater than the ice-making cycle. If the first reference value is not less than the ice bank capacity, the process proceeds to step S16, where the ice bank capacity is set to the full ice determination reference value.
And S14, judging whether the average ice-taking time interval is larger than an ice-making period.
And after determining that the first reference value is smaller than the ice storage box capacity, continuously judging the relation between the average ice taking time interval and the ice making period. Specifically, the ice making cycle refers to a time interval of the ice making device in two adjacent ice making processes. The ice making cycle is typically a preset value. When the average ice fetching time interval is greater than the ice making period, it indicates that the ice fetching frequency of the user is low, and at this time, step S15 is executed to set the first reference value as the full ice judgment reference value.
S15, the first reference value is set as a full ice determination reference value.
At this time, the first reference value is smaller than the capacity of the ice storage box, and the average ice taking time is larger than the ice making period, which indicates that the user needs low ice, the full ice judgment reference value can be set as a small first reference value, the total ice making amount of the ice making device can be reduced, and the ice making device does not need to consume electric quantity to store a large amount of ice blocks; and the control system can stop continuously making ice in time after judging that the ice blocks in the ice storage box reach the first reference value, and start making ice after the user takes the ice so as to keep the ice blocks fresh.
S16, the ice bank capacity is set to a full ice determination reference value.
At this time, the first reference value is not less than the ice bank capacity or the average ice-taking time is not greater than the ice-making cycle. That is, at this time, the user may set the ice storage capacity (i.e., the maximum value of storable ice) as the full ice determination reference value with a large ice pickup amount or a high ice pickup frequency.
The control method of the ice making device can determine the reference value of full ice judgment according to the average ice taking time interval and the average ice taking amount of a user in the preset time; when the user does not take ice for a long time, the full ice judgment reference value can be set to be smaller, the total ice making quantity of the ice making device can be reduced, and the electric quantity does not need to be consumed to store a large number of ice blocks; in addition, the utilization rate of ice cubes of a user is improved, and the freshness of the ice cubes is kept.
Further, after step S14, the method further includes:
and S17, judging whether the average ice-taking amount is less than the single ice-making amount.
And when the average ice-taking time interval is not more than the ice-making period, judging whether the average ice-taking amount is less than the single ice-making amount or not. The single ice making amount refers to the weight of ice made by the ice making tray after performing an ice making process once. Comparing the average ice-fetching amount with the single ice-making amount, if the average ice-fetching amount is smaller than the single ice-making amount, indicating that the ice-fetching amount is small, executing the step S15, and setting the first reference value as a full ice judgment reference value; if the average ice-fetching amount is not less than the single ice-making amount, which indicates that the ice-fetching amount is large, the step S16 is executed to set the ice bank capacity as the full ice determination reference value.
As shown in fig. 2, before step S11, the method further includes:
and S101, recording the ice taking times within the preset time.
The preset time can be 1 day, 1 week or 1 month, can be preset in the program of the ice making device, and can also be set according to the specific needs of the user. The embodiment of the present invention will be described with reference to 1 month as an example. For example, the user takes ice 3 times in a 1 week period.
And S102, recording the time interval between two adjacent ice taking within the preset time.
Within 1 week, the interval between the 1 st ice harvest and the 2 nd ice harvest is 10 hours, and the interval between the 2 nd ice harvest and the 3 rd ice harvest is 20 hours.
And S103, calculating an average ice-taking time interval according to the ice-taking times and the time intervals of two adjacent ice-taking times.
As mentioned above, the average ice harvest interval is: (10 + 20)/2 =15 hours.
As shown in fig. 3, after step S101, the method further includes:
and S104, recording the current ice storage amount in the ice storage box.
Before each time of taking ice, the current ice storage amount in the ice storage box is recorded. For example, the current ice storage amounts before the 1 st, 2 nd and 3 rd ice fetches are 5kg, 4.5kg and 4.1kg, respectively.
And S105, recording the ice storage amount after ice taking after each ice taking.
After the ice is taken for the 1 st time, the 2 nd time and the 3 rd time, the ice storage amount after ice taking is 4.5kg, 4.1kg and 3.8kg respectively.
And S106, calculating the single ice taking amount according to the current ice storing amount and the ice storing amount after ice taking.
The single ice harvest for the 1 st, 2 nd and 3 rd harvest can be calculated to be 5-4.5=0.5kg, 4.5-4.1=0.4kg, 4.1-3.8=0.3kg, respectively.
And S107, calculating the average ice-taking amount according to the ice-taking times and the single ice-taking amount.
The average ice harvest was (0.5 +0.4+ 0.3)/3 =0.4kg over a 1 week period.
As shown in fig. 4, after step S104 and before step S105, the method further includes:
s1041, after each time of ice taking, detecting a real-time distance from the distance sensor to the surface of the ice blocks in the ice storage box.
Specifically, the distance sensor is disposed above the ice bank at a position corresponding to an upper opening thereof, that is, a distance from the distance sensor to a bottom wall of the ice bank is a height of the ice bank. After each ice pick, the distance sensor can detect the real-time distance L from the distance sensor to the surface of the ice cubes in the ice storage box.
And S1042, calculating the height of the real-time ice blocks according to the height of the ice storage box and the real-time distance.
Ice bank height H 0 Generally, the real-time distance L is a preset value, and the real-time ice block height M can be calculated in the following manner: m = H 0 -L。
And S1043, calculating the ice storage amount after ice taking according to the real-time ice block height, the bottom area of the ice storage box and the ice block density.
At this time, the real-time ice height M is known, and the ice bank floor area S can be calculated from the length, width and height parameters of the ice bank, and the ice density p is also known. The ice storage amount Q = M × S × p after the ice is taken can be obtained.
As shown in fig. 5, after step S15, the method further includes:
and S151, setting the wind speed of the ice making fan as a first wind speed, wherein the first wind speed is less than the rated wind speed.
At this time, the first reference value is set as a full ice judgment reference value, and the first reference value is smaller than the capacity of the ice storage box, which shows that the ice demand of a user is not large, the rotating speed of the ice making fan can be reduced, less cold energy is used for refrigeration, and the energy consumption and the noise are further reduced. Accordingly, the wind speed of the ice making fan can be set to a first wind speed less than the rated wind speed. The rated wind speed is generally the normal wind speed preset by the ice making fan.
After step S16, the method further includes:
and S161, setting the wind speed of the ice making fan to be a second wind speed, wherein the second wind speed is greater than the rated wind speed.
In this case, the ice bank capacity is set to the full ice determination reference value, which indicates that the demand for ice by the user is large and a large amount of ice needs to be made quickly. The rotating speed of the fan is increased, the cold quantity is increased, and rapid ice making is carried out, so that the wind speed of the ice making fan can be set to be a second wind speed which is greater than the rated wind speed.
Referring to fig. 6-7, a control system 200 for an ice making apparatus is provided according to an embodiment of the present invention. As shown in fig. 6, the control system may include: a calculating unit 210, a determining unit 220, a judging unit 230 and a processing unit 240.
The calculating unit 210 may be configured to calculate an average ice fetching time interval and an average ice fetching amount within a preset time. Specifically, the preset time may be set to 1 week or 1 month, and the average ice-fetching time interval and the average ice-fetching amount for the user to fetch ice are calculated during the preset time. The ice-taking time interval refers to the time length of the user between two adjacent ice-taking processes, and the average ice-taking time interval is the average value of the time lengths of the user between two adjacent ice-taking processes; the ice-picking amount refers to the weight of ice picked up by a user each time the ice is picked up, and the average ice-picking amount is the average value of the weights of ice picked up by the user each time the ice is picked up.
The determining unit 220 may be configured to determine a first reference value according to the average ice harvest. Specifically, the first reference value is set as the average ice picking amount plus a redundancy amount, and the redundancy amount is set according to experiments or experience, and generally speaking, the redundancy amount is set to be between 5% and 20% of the average ice picking amount. Generally, the amount of ice used by the user at a time is kept at a value that is not very different, and therefore, if the amount of ice stored in the ice bank is kept at the level of the average amount of ice taken, the ice using requirement of the user in most cases can be satisfied. However, the user may occasionally take ice larger than the average amount of ice taken, and therefore, the first reference value is set to the average amount of ice taken plus the redundancy amount in order to satisfy the situation that the user takes ice more than the average amount of ice taken at a certain time.
The judging unit 230 may be configured to judge whether the first reference value is less than the ice bank capacity. Generally, in the related art, the ice bank capacity is set to the full ice determination reference value. As can be seen from the above, the first reference value is the sum of the average ice-fetching amount and the redundancy amount, and thus the first reference value is likely to be larger than the capacity of the ice bank. When the first reference value is larger than the capacity of the ice bank, the first reference value is set as the full ice judgment reference value, which may cause the problem of ice cubes in the ice bank overflowing. When the first reference value is smaller than the ice bank capacity, it indicates that the amount of ice taken by the user each time is small, that is, a smaller value may be set as the full ice determination reference value. Therefore, it is first necessary to judge the magnitude relation of the first reference value and the ice bank capacity to determine the subsequent step with the judgment result.
The judgment unit 230 may be further configured to judge whether the average ice-fetching time interval is greater than an ice-making cycle if the first reference value is less than the ice bank capacity. And after determining that the first reference value is smaller than the ice storage box capacity, continuously judging the relation between the average ice taking time interval and the ice making period. Specifically, the ice making cycle refers to a time interval between two adjacent ice making processes of the ice making device. The ice making cycle is typically a preset value. And when the average ice fetching time interval is greater than the ice making period, the ice fetching frequency of the user is lower.
The processing unit 240 may be configured to set the first reference value as a full ice determination reference value if the average ice-fetching time interval is greater than an ice-making period. At this time, the user needs low ice, and the full-ice judgment reference value can be set as a first small reference value, so that the total ice making quantity of the ice making device is reduced, and the electric quantity is not required to be consumed to store a large quantity of ice blocks; and, after determining that the ice cubes inside the ice storage box reach the first reference value, the processing unit 240 may timely control the ice making tray to stop making ice continuously, and start making ice after the user picks up ice, so as to keep the ice cubes fresh.
The processing unit 240 is further configured to set the ice bank capacity to a full ice determination reference value if the first reference value is not less than the ice bank capacity. At this time, the user may set the ice storage capacity (i.e., the maximum value of the storable ice) as the full ice determination reference value when the ice pickup amount is large or the ice pickup frequency is high.
Further, when the average ice fetching time interval is not greater than the ice making period, the determining unit 230 is further configured to determine whether the average ice fetching amount is less than a single ice making amount. The single ice making amount refers to the weight of ice made by the ice making tray after performing an ice making process once. Comparing the average ice-fetching quantity with the single ice-making quantity, if the average ice-fetching quantity is less than the single ice-making quantity, it is indicated that the ice-fetching quantity is less,
when the average ice-fetching amount is smaller than the single ice-making amount, the processing unit 240 is further configured to set the first reference value as a full ice determination reference value. The processing unit 240 is further configured to set the ice bank capacity to a full ice determination reference value when the average ice-making amount is not less than the single ice-making amount.
In the embodiment of the present invention, as shown in fig. 7, the control system may further include a recording unit 250, where the recording unit 250 is configured to record the number of times of ice harvesting within a preset time and record a time interval between two adjacent times of ice harvesting within the preset time. The preset time can be 1 day, 1 week or 1 month, can be preset in the program of the ice making device, and can also be set according to the specific needs of the user. The embodiment of the present invention will be described with reference to 1 month as an example. For example, the user takes ice 3 times in a 1 week period. Within 1 week, the interval between the 1 st ice harvest and the 2 nd ice harvest is 10 hours, and the interval between the 2 nd ice harvest and the 3 rd ice harvest is 20 hours.
The computing unit 210 is further configured to: and calculating the average ice-taking time interval according to the ice-taking times and the time interval of two adjacent ice-taking times. As mentioned above, the average ice harvest interval is 1 week: (10 + 20)/2 =15 hours.
The recording unit 250 is further configured to: and recording the current ice storage amount in the ice storage box. After each ice pick-up, the amount of ice stored after the ice pick-up is recorded. Before each time of taking ice, the current ice storage amount in the ice storage box is recorded. For example, the current ice storage amounts before the 1 st, 2 nd and 3 rd ice fetches are 5kg, 4.5kg and 4.1kg, respectively. After the ice is taken for the 1 st time, the 2 nd time and the 3 rd time, the ice storage amount after ice taking is 4.5kg, 4.1kg and 3.8kg respectively.
The computing unit 210 is further configured to: calculating the single ice taking amount according to the current ice storing amount and the ice storing amount after ice taking; and calculating the average ice-taking amount according to the ice-taking times and the single ice-taking amount.
The single ice taking amount of the 1 st ice taking, the 2 nd ice taking and the 3 rd ice taking can be calculated to be 5-4.5=0.5kg, 4.5-4.1=0.4kg and 4.1-3.8=0.3kg respectively. The average amount of ice taken over the 1 week period was (0.5 +0.4+ 0.3)/3 =0.4 kg.
In an embodiment of the present invention, as shown in fig. 7, the control system may further include a detection unit 260, and the detection unit 260 may be configured to detect a real-time distance from the distance sensor to the surface of the ice cubes inside the ice storage box. Specifically, the distance sensor is disposed above the ice bank at a position corresponding to an upper opening thereof, that is, a distance from the distance sensor to a bottom wall of the ice bank is a height of the ice bank. After each ice pick, the distance sensor can detect the real-time distance L from the distance sensor to the surface of the ice cubes in the ice storage box.
The calculating unit 210 is further configured to calculate a real-time ice height according to the ice bank height and the real-time distance; and calculating the ice storage amount after ice taking according to the real-time ice block height, the bottom area of the ice storage box and the ice block density.
Ice bank height H 0 Generally, the real-time distance L is a preset value, and the real-time ice block height M can be calculated in the following manner: m = H 0 -L. The ice bank floor area S can be calculated from the length, width, and height parameters of the ice bank, and the ice density p is also a known number. The stored ice amount Q = M × S × p after the ice is taken can be obtained.
In the embodiment of the present invention, as shown in fig. 7, the control system may further include a wind speed adjusting unit 270. The wind speed adjusting unit 270 may be configured to set the wind speed of the ice making fan to a first wind speed if the first reference value is set to the ice-full determination reference value, the first wind speed being less than the rated wind speed. At this time, the first reference value is set as a full ice judgment reference value, and the first reference value is smaller than the capacity of the ice storage box, which shows that the ice demand of a user is not large, the rotating speed of the ice making fan can be reduced, less cold energy is used for refrigeration, and the energy consumption and the noise are further reduced. Accordingly, the wind speed of the ice making fan can be set to a first wind speed less than the rated wind speed. The rated wind speed is generally the normal wind speed preset by the ice making fan.
The wind speed adjusting unit 270 may be further configured to set the wind speed of the ice making fan to a second wind speed, which is greater than the rated wind speed, if the ice bank capacity is set to the full ice determination reference value.
In this case, the ice bank capacity is set to the full ice determination reference value, which indicates that the user has a large demand for ice and needs to make a large amount of ice quickly. The rotating speed of the fan is increased, the cold quantity is increased, and rapid ice making is carried out, so that the wind speed of the ice making fan can be set to be a second wind speed which is greater than the rated wind speed.
