In the prior art, some beverage making methods for making smoothies and slush are available, and crystallization phenomenon occurs in the beverage by controlling the temperature of the beverage storage device, so that the smoothies and slush beverages are obtained. However, when the beverage once assumes a smoothie, slush state, there is an inconvenient problem in pouring out; the coarse ice crystal granular sensation can be obviously perceived at the inlet of the ice-sand or ice-mud state beverage, and the taste requirements of some groups are not necessarily met; meanwhile, the target state of the beverage is kept, and the target temperature needs to be kept for a longer time, but the temperature fluctuation of the beverage storage device is influenced due to the events such as door opening and closing, defrosting and the like in the refrigerating process, so that the refrigerating effect is influenced. To solve at least one of the above problems, a first embodiment of the present application discloses a control method of a refrigerating apparatus for making a icy drink.
Fig. 1 shows a flowchart of a control method disclosed in an embodiment of the present application, where the control method may be used to control a refrigerating apparatus for making a icy drink, and the detailed description is as follows:
In S101, a real-time temperature Tt in the refrigerating apparatus is acquired.
In the present embodiment, the refrigeration apparatus may exemplarily employ a compressor as a core member. For example, the refrigerating apparatus may include a compressor for driving a refrigerant to the evaporator to exchange heat, i.e., generate cool air, an evaporator, a fan for introducing cool air from the evaporator into the closed space in which the beverage is placed, and a closed space. A temperature sensor may be used to detect the real-time temperature Tt within the refrigeration device, the type of sensor being not limited. Specifically, the temperature sensor may detect that the beverage is in a closed 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;
and when the real-time temperature Tt is in a second preset temperature interval, controlling the refrigerating device to work in a second mode, wherein the refrigerating device works in a second power in the second mode, 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 when the temperature is greater than or equal to T11, the first preset temperature interval is located, and the second preset temperature interval has a maximum value T22 and a minimum value T21, wherein T22 is equal to T11, and when the temperature is less than T22 and greater than or equal to T21, the second preset temperature interval is located.
The present embodiment is achieved by dividing the refrigeration process into a first mode in which the refrigeration device operates at a first power and a second mode in which the refrigeration device operates at a second power, the first power being greater than the second power. By the arrangement, the refrigerating device can work by adopting a larger first power when the temperature is not reduced at the beginning of working, so that the refrigerating device can quickly reach a second preset temperature interval and enter a second mode, and the running time in the first mode is reduced. In the second mode, a smaller second power is used to control the operation of the refrigeration device, and because the temperature is reduced to be close to the target temperature in the second mode, accurate, efficient and energy-saving temperature control can be realized by using smaller power.
Alternatively, the first mode may be entered after the compressor of the refrigeration device is started. At this time, the initial temperature of the closed space of the refrigeration device is located in a first preset temperature interval. The first mode may also be entered after the compressor has completed a start-up phase, e.g., the first mode may be entered after a predetermined start-up phase, which may include a gradual increase in the frequency at which the compressor is started up to a 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 less than the maximum value of the second preset temperature interval for the first time, the refrigerating device is controlled to enter a second mode to operate. In this optional embodiment, when the real-time temperature is less than the maximum value of the second preset temperature interval, the refrigerating device is controlled to enter the second mode to work, so that an event that the refrigerating device jumps between the first mode and the second mode due to temperature fluctuation can be avoided, and the stability of the working of the refrigerating device is facilitated. In addition, in the working process of the second mode, if the difference 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 the door of the refrigerating device is opened and a large amount of beverage is put into the refrigerating device, the real-time temperature is inevitably changed greatly, and the refrigerating device is required to return to the first mode to work at the moment, so that the aim of rapid refrigeration is fulfilled.
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 from the first real-time temperature change rate. Such setting of the second power is not arbitrary but is related to the rate of change of temperature 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 the efficiency and accuracy of refrigeration. In this embodiment, the first real-time temperature change rate may be calculated by using the difference between the real-time temperature and T11 at the time of entering the first mode and the duration T1 of the first mode, for example. The specific calculation method is not particularly limited in the present embodiment.
In some embodiments, the magnitude of the second power is inversely related to the first real-time temperature change rate. That is, the greater the first real-time temperature change rate, the less the second power; the smaller the first real-time temperature change rate, the greater the second power. The larger the first real-time temperature change rate is, the smaller the refrigeration load related to factors such as the volume of the closed space where the beverage is located, the quantity of the beverage and the like is, and in order to accurately control the temperature, the overshoot is reduced, the energy efficiency is improved, and the smaller second power can be adopted. The smaller the first real-time temperature change rate, the larger the refrigeration load related to factors such as the volume of the closed space where the beverage is located, the quantity of the beverage and the like, and the second power which is slightly larger is selected in order to be capable of taking the quick and energy efficiency of temperature regulation into consideration. Specifically, a standard second power may be set, and then the second power is calculated using a product of a coefficient inversely related to the first real-time temperature change rate 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 the 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 adding a second preset deviation delta T2 to the freezing point temperature to obtain the minimum value of the second preset temperature interval, wherein the second preset deviation delta T2 = beta (Tj-Td), the second deviation coefficient beta is a positive number smaller than 1, and the alpha + beta is a positive number smaller than 1.
In this embodiment, the second preset temperature interval is set by using the preset deviation, the crystallization point temperature Tj and the freezing point temperature Td of the beverage, and in this temperature interval, the taste of the beverage is better.
In this embodiment, the meaning of a ballast beverage may be further defined as: in the beverage resting state, the beverage assumes a liquid state substantially identical to that in the normal temperature state; floc appears when the beverage is poured into a container such as a wine glass or a beverage cup. Fig. 3 shows a smoothie beverage, where the beverage in the container 30 exhibits more smoothie and it is clear that there is relatively more smoothie in the region 31, and the drinker will experience significantly more ice crystal particles after the beverage has been introduced in this state. As shown in fig. 2, in the state of beer beverage in the second preset temperature zone in this embodiment after being poured into the container 20, the interior of the beverage is clearly seen in the region 21, and the beverage in this state is soft, soft and delicious, and smooth, and no obvious ice crystal particles are perceived by drinkers. In both fig. 2 and fig. 3 beer is taken as an example.
In some embodiments, the first deviation coefficient α in the first preset deviation Δt1=α (Tj-Td) is smaller than the second deviation coefficient β in the second preset deviation Δt2=β (Tj-Td), so that the beverage in the second preset temperature interval is more likely to generate more floc when poured, and the reliability of making the icy beverage is improved.
It will be appreciated that conversely, if the first deviation factor α is set to be greater than the second deviation factor β, the resulting beverage in the second predetermined temperature interval will more readily produce more ice crystal particles when poured.
In this embodiment, the setting of the second preset temperature interval, that is, the setting of the temperature interval in which the beverage is finally obtained, it can be understood that the setting of the target temperature interval of the beverage may also be independently implemented independent of other control methods in the embodiment, that is, no matter what refrigeration strategy is adopted, the setting of the target temperature interval of the beverage by the foregoing method is not affected.
In some embodiments the maximum value of the second preset temperature interval minus the minimum value of the second preset temperature interval is less than or equal to 1 ℃. In this embodiment, the temperature variation range of the second preset temperature interval is further defined to be less than or equal to 1 ℃, and under the control precision, the reliability of making the icy slag beverage can be improved.
In some embodiments, the duration t2 of the second mode is greater than 2 hours. The embodiment ensures that the duration of the beverage in the target temperature interval is within a certain range by limiting the duration of the beverage in the target temperature interval, so that the state of the beverage is relatively stable, and the reliability of making the ballast beverage can be improved.
In some embodiments, a container, such as a wine glass, may be co-located in the refrigeration device such that the walls of the container have the same temperature within a second preset temperature interval. It is of course also possible to bring the container to a temperature within this second predetermined temperature interval by other means or devices. In this case, the floc is more durable after the beverage in the second preset temperature interval is introduced into the container, and the reliability of making the icy beverage is improved.
In some embodiments, the cooling device includes an evaporator and a fan for directing cool air from the evaporator into the space in which the beverage is placed, and the duration t2 of the second mode is positively correlated with the number of defrosted times of the evaporator and the number of door openings of the cooling device.
In this embodiment, since the evaporator of the refrigeration apparatus needs to perform the defrosting process, the refrigeration apparatus may generate door opening events, which may cause temperature fluctuations in the refrigeration apparatus to affect the state of the beverage, and thus the duration of the second mode needs to be compensated, the duration of the second mode is associated with the above events, and the duration of the second mode is prolonged as the number of defrosting times and the door opening events increase.
In some embodiments, the duration t2 is a sum of a standard duration ts plus a varying duration Δt, and the control method further includes:
acquiring a second real-time temperature change rate in the standard time length range in the second mode, and timing a time length sum of the second real-time temperature change rate being larger than a preset change threshold value, wherein the second real-time temperature change rate is an absolute value of a change rate of the real-time temperature Tt in the standard time length range in the second mode in an ascending trend;
The time duration Δt of the change is positively correlated with the time duration sum.
In this embodiment, there is no need to count the number of defrost times and door opening events. And summing up the time periods in which the temperature in the standard time period in the duration of the second mode is in the rising trend and exceeds the preset change threshold value to obtain the time period sum. The above events often occur with the result of a rise in temperature, or, for precise control, are more closely related to the effect of the above events on temperature fluctuations, as they are the direct factors affecting the stability of the beverage state. Therefore, the event that the temperature in the standard time period is in the rising trend is concerned, and the time period statistics is carried out when the preset change threshold value is exceeded by setting the preset change threshold value, so that the normal temperature change phenomenon can be eliminated. Setting the change duration delta t and the duration sum in positive correlation, wherein the longer the instant duration sum is, the longer the change duration delta t to be compensated is, so that the reasonable duration of the second mode is set, and the reliability of beverage making can be high under the condition of low energy consumption.
