In the prior art, some beverage making methods for making the smoothie and the slush exist, and the temperature of a beverage storage device is controlled to enable the crystallization phenomenon to occur in the beverage, so that the smoothie and slush beverage is obtained. However, there is an inconvenience in pouring out the beverage once it is in a state of slush or slush; the entrance of the beverage in the ice-sand or ice-mud state can obviously feel rough ice crystal granular sensation and does not necessarily meet the taste requirements of some groups; meanwhile, the target state of the beverage needs to be maintained for a long time at the target temperature, but the refrigeration effect is affected because the temperature fluctuation of the beverage storage device is affected by the events of opening and closing the door, defrosting and the like in the refrigeration process. In order to solve at least one of the above problems, a first embodiment of the present application discloses a method for controlling a refrigerating apparatus for producing a frozen beverage.
Fig. 1 shows a flowchart of an implementation of a control method disclosed in an embodiment of the present application, which can be used for controlling a refrigerating apparatus for making a frozen beverage, and is detailed as follows:
in S101, a real-time temperature Tt in the refrigeration apparatus is acquired.
In the present embodiment, the refrigeration apparatus may exemplarily employ a compressor as a refrigeration apparatus of a core component. For example, the refrigeration device may include a compressor, an evaporator, a fan for guiding cold air from the evaporator into the enclosed space in which the beverage is placed, and an enclosed space, and the compressor is configured to drive a refrigerant to the evaporator to perform heat exchange, i.e., generate cold air. A temperature sensor may be used to detect the real-time temperature Tt within the refrigeration unit, the type of sensor not being limiting. In particular, the temperature sensor may detect that the beverage is located in the enclosed space.
In S102, when the real-time temperature Tt is within a first preset temperature interval, controlling the refrigeration device to operate in a first mode, where the refrigeration device operates at a first power in the first mode;
and when the real-time temperature Tt is within a second preset temperature interval, controlling the refrigerating device to work in a second mode, wherein in the second mode, the refrigerating device works at a second power, the second power is smaller than the first power, and the second preset temperature interval and the first preset temperature interval form a continuous interval.
Specifically, the first preset temperature interval has a minimum value T11, and is located in the first preset temperature interval if being greater than or equal to T11, and the second preset temperature interval has a maximum value T22 and a minimum value T21, where T22 is equal to T11, and is located in the second preset temperature interval if being less than T22 and greater than or equal to T21.
The present embodiment divides the cooling process into a first mode and a second mode, and the cooling device operates at a first power in the first mode and at a second power in the second mode, and the first power is greater than the second power. The arrangement can enable the refrigerating device to work at a larger first power when the temperature is not reduced at the beginning of the operation, so that the refrigerating device can quickly reach the second preset temperature interval and enter the second mode, and the operation time in the first mode is reduced. In the second mode, a smaller second power is used to control operation of the refrigeration unit, and since the temperature has been reduced to near the target temperature in the second mode, accurate, energy efficient temperature control can be achieved using the smaller power.
Alternatively, the first mode may be entered after the compressor of the refrigeration unit is started. At this time, the initial temperature of the closed space of the refrigerating device is within the first preset temperature interval. The first mode may also be entered after the compressor completes the start-up phase, for example, the first mode may be performed after a preset start-up phase, where the preset start-up phase may include that the frequency of the start-up of the compressor gradually increases to reach the target frequency to complete the start-up process. After the start-up phase is completed, the first mode may be entered.
Optionally, when the real-time temperature Tt is first smaller than the maximum value of the second preset temperature interval, the refrigeration device is controlled to enter a second mode to operate. In this optional embodiment, when the real-time temperature is lower than the maximum value of the second preset temperature interval, the refrigeration device is controlled to enter the second mode to operate, so that an event that the refrigeration device jumps between the first mode and the second mode due to temperature fluctuation can be avoided, and the operation stability of the refrigeration device is facilitated. In addition, in the working process of the second mode, if the difference value between the real-time temperature and the maximum value of the second preset temperature interval exceeds the preset temperature difference threshold value, the refrigerating device can be controlled to return to the first mode to work. For example, when a door of the refrigeration device is opened and a large amount of beverages are put into the refrigeration device, a real-time temperature is inevitably changed greatly, and at the moment, the refrigeration device needs to return to the first mode to work so as to achieve the purpose of rapid refrigeration.
In S103, calculating a first real-time temperature change rate of the real-time temperature Tt in the first mode, and determining a value of the second power according to the first real-time temperature change rate; the first real-time temperature change rate is an absolute value of a change rate of the real-time temperature Tt in the first mode.
In this embodiment, the value of the second power is determined in accordance with a first real-time rate of temperature change. Such setting of the second power is not arbitrarily set but is correlated with the rate of temperature change in the first mode. The temperature change rate in the first mode reflects the size of the refrigeration load, so that the second power is set to be related to the temperature change rate in the first mode, the second power can be directly and conveniently related to the refrigeration load, complex load calculation steps are not needed, and the calculation result is more accurate. The value of the second power set in this way can give consideration to both the efficiency and the accuracy of the refrigeration. In the present embodiment, for example, the first real-time temperature change rate may be calculated using the difference between the real-time temperature at the time of entering the first mode and T11 and the duration T1 of the first mode. The specific calculation manner is not particularly limited in this embodiment.
In some embodiments, the magnitude of the second power is inversely related to the first real-time rate of temperature change. That is, the greater the first real-time rate of temperature change, the smaller the second power; the smaller the first real-time rate of temperature change, the greater the second power. The greater the first real-time temperature change rate, the lower the refrigeration load associated with the volume of the enclosed space in which the beverage is located, the quantity of beverage, etc., and a lower second power may be used in order to enable accurate temperature control, reduce overshoot, and improve energy efficiency. The smaller the first real-time temperature change rate is, the larger the refrigeration load related to the volume of the closed space in which the beverage is placed, the number of beverages, and the like is, and the second power is selected to be slightly larger in order to allow for rapidity and energy efficiency of temperature adjustment. Specifically, a standard second power may be set, and then the second power may be calculated using a product of a coefficient that is inversely related to the first real-time rate of temperature change and the standard second power.
In some embodiments, the control method further comprises:
obtaining a crystallization point temperature Tj and a freezing point temperature Td of the beverage, and subtracting a first preset deviation delta T1 from the crystallization point temperature to obtain a maximum value of the second preset temperature interval, wherein the first preset deviation delta T1= alpha (Tj-Td), and a first deviation coefficient alpha is a positive number smaller than 1; and obtaining the minimum value of the second preset temperature interval according to the freezing point temperature plus a second preset deviation delta T2, wherein the second preset deviation delta T2= beta (Tj-Td), a second deviation coefficient beta is a positive number smaller than 1, and alpha + beta is a positive number smaller than 1.
In this embodiment, the preset deviation, the crystallization point temperature Tj of the beverage and the freezing point temperature Td are used to set a second preset temperature interval in which the taste of the beverage is better.
In this embodiment, the meaning of the ballast beverage may be further defined as: in the static state of the beverage, the beverage is in a liquid state basically the same as that in the normal temperature state; when the beverage is poured into a container such as a wine glass or a drinking glass, the beverage is flocculent. In the case of a slush-type beverage, shown in figure 3, the beverage in the container 30 is more slush, and in the region 31 it is clearly seen that there is more slush in the beverage, and the beverage in this condition is in the mouth and the consumer perceives ice crystal particles clearly. As shown in fig. 2, in the present embodiment, the beer beverage in the second predetermined temperature range is in the state after being poured into the container 20, and it is clearly seen in the region 21 that the inside of the beverage is flocculent, and the beverage in this state is soft and delicious and smooth at the inlet, and the drinker does not feel obvious ice crystal particles. In both fig. 2 and fig. 3, beer is taken as an example.
In some embodiments, a first deviation coefficient α of the first predetermined deviation Δ T1= α (Tj-Td) is smaller than a second deviation coefficient β of the second predetermined deviation Δ T2= β (Tj-Td), so that the beverage in the second predetermined temperature interval is more likely to generate more flocs when poured out, thereby improving the reliability of making the beverage.
It will be appreciated that, conversely, if the first deviation factor α is set to be greater than the second deviation factor β, the beverage in the second predetermined temperature interval thus obtained is more likely to produce a greater number of ice crystal particles when poured.
In this embodiment, the second preset temperature interval is set, that is, the temperature interval for finally obtaining the beverage is set, and it can be understood that the setting of the target temperature interval of the beverage can also be independently implemented independently from other control methods in the embodiment, that is, the setting of the target temperature interval of the beverage by using the foregoing method is not affected no matter what refrigeration strategy is adopted.
In some embodiments, the maximum value of the second predetermined temperature interval minus the minimum value of the second predetermined temperature interval is less than or equal to 1 ℃. The embodiment further limits the temperature variation range of the second preset temperature interval to be less than or equal to 1 ℃, and under the control precision, the reliability of the preparation of the ice slag beverage can be improved.
In some embodiments, the duration t2 of the second mode is greater than 2 hours. The embodiment limits the duration of the beverage in the target temperature interval, so that the duration is ensured to be within a certain range, the state of the beverage is relatively stable, and the reliability of making the ice slag beverage can be improved.
In some embodiments, containers, such as wine glasses, may be placed together in the refrigeration unit such that the walls of the containers have the same temperature within a second predetermined temperature interval. It is of course also possible to use other means or devices for bringing the wall of the container to a temperature within this second predetermined temperature interval. In this case, after the beverage in the second preset temperature interval is introduced into the container, the floccules are more abundant and durable, and the reliability of the preparation of the ice-ballast beverage is improved.
In some embodiments, the refrigeration apparatus includes an evaporator and a fan for guiding cool air from the evaporator into a space where a beverage is placed, and the duration t2 of the second mode is positively correlated with the number of times of defrosting of the evaporator and the number of times of opening a door of the refrigeration apparatus.
In this embodiment, since the evaporator of the refrigeration device needs to be defrosted, the refrigeration device may be subjected to a door opening event, which may cause temperature fluctuations within the refrigeration device and affect the state of the beverage, and therefore, the duration of the second mode may need to be compensated, which is associated with the above events, and the duration of the second mode may be extended as the number of defrosted times and the door opening event increase.
In some embodiments, the duration t2 is the sum of the standard duration ts plus the variation duration Δ t, and the control method further includes:
acquiring a second real-time temperature change rate in the standard time length range in the second mode, timing the sum of time lengths of which the second real-time temperature change rate is greater than a preset change threshold value, wherein the second real-time temperature change rate is the absolute value of the change rate of the real-time temperature Tt in the standard time length range in the second mode in the ascending trend;
the duration of change Δ t is positively correlated with the sum of said durations.
In this embodiment, no statistics need be made on the number of defrost times and door opening events. And the time lengths of the second mode, in which the temperature in the standard time length is in the rising trend and exceeds the preset change threshold value, are summed to obtain the sum of the time lengths. The above events often occur as a result of a temperature rise, or, for precise control, the effect of the event on temperature fluctuations is of greater concern, since it is temperature fluctuations that are the direct factor in affecting the stability of the beverage state. Therefore, the event that the temperature in the standard time length is in the rising trend is focused, the time length statistics is carried out only when the preset change threshold value is exceeded through setting the preset change threshold value, and the normal temperature change phenomenon can be eliminated. The change time duration deltat is positively correlated with the sum of the time durations, and the longer the sum of the time durations, the longer the change time duration deltat to be compensated, so that the reasonable duration of the second mode is set, and the reliability of the beverage making can be too high with the lowest energy consumption as possible.
