In another aspect, the present invention further provides a control method of a cosmetic refrigerator, and particularly, the control method may be as shown in fig. 4. Specifically, in fig. 4, the control method may include:
in step S10, the outdoor temperature is acquired. Wherein, the temperature sensor is adopted to monitor the temperature outside the refrigerator body 2 in real time.
In step S11, it is determined whether the outdoor temperature is greater than the highest temperature of the preset temperature range. Wherein, the preset temperature range which needs to be reached inside the refrigerator body 2 is adjusted according to the storage temperature range of the cosmetics which need to be placed. At this time, the outdoor temperature and the preset temperature range are judged, so that the subsequent driving refrigeration assembly can adjust the temperature inside the refrigerator body 2 to the preset temperature range.
In step S12, the cooling module is activated when it is determined that the outdoor temperature is greater than the highest temperature of the preset temperature range. If the outdoor temperature is higher than the highest temperature of the preset temperature range, it indicates that the external temperature is high, and the interior of the refrigerator body 2 needs to be cooled, so that the refrigeration assembly is started to reduce the temperature inside the refrigerator body 2.
In step S13, temperature values at a plurality of times within a preset time period of the current time of the first cavity 12 are obtained. The temperature inside the first cavity 12 is monitored in real time by using a temperature sensor, and a plurality of temperature values are acquired within a preset time period at the current moment.
In step S14, a linear fit equation of the temperature at the present time is calculated according to equation (1),
y＝kt+b，
arg mink，b LOSS， (1)
wherein y is a temperature value of the temperature linear fitting equation, k is a slope of the temperature linear fitting equation, b is a longitudinal intercept of the temperature linear fitting equation, LOSS is a sum of squares of residuals, n is a total number of acquisitions, i is 1, 2iIs the time of the i-th acquisition,
is tiLinear fit value of temperature over time, y (t)i) Is acquired tiTemperature value at time, argmink，bLOSS represents the value of k and b at which LOSS is a minimum.
In step S15, the first chamber temperature at the present time is calculated according to equation (2),
T＝ktT+b， (2)
wherein, tTIntermediate time, t, of a predetermined time period for the current timeaInitial time, t, of a predetermined time period for the current timebAnd T is the temperature of the first cavity at the current moment.
In step S16, it is determined whether the first cavity temperature is less than or equal to the highest temperature of the preset temperature range. And comparing the calculated temperature of the first cavity with the highest temperature within a preset temperature range to judge whether the refrigeration effect of the refrigeration assembly reaches an expected state.
In step S17, when the first cavity temperature is determined to be less than or equal to the highest temperature of the preset temperature range, it is determined again whether the first cavity temperature is greater than or equal to the lowest temperature of the preset temperature range. If the temperature of the first cavity is less than or equal to the highest temperature of the preset temperature range, the refrigerating effect of the refrigerating assembly is good, and the temperature inside the refrigerator body 2 is gradually reduced. In order to keep the temperature inside the refrigerator body 2 within the preset temperature range, it is necessary to determine again whether the temperature of the first cavity is greater than or equal to the lowest temperature of the preset temperature range.
In step S18, when it is determined that the first cavity temperature is greater than or equal to the lowest temperature of the preset temperature range, it is determined again whether the absolute value of the slope of the temperature linear fitting equation is less than the slope threshold. If the first cavity temperature is greater than or equal to the lowest temperature of the preset temperature range, it indicates that the first cavity temperature is within the preset temperature range at this time. In order to maintain the constant temperature state inside the refrigerator body 2 and reduce the temperature fluctuation inside the refrigerator body 2, the absolute value of the slope of the temperature linear fitting equation needs to be judged and controlled within the range of the slope threshold, so as to avoid the situation of overlarge temperature change.
In step S19, in the case where the absolute value of the slope of the temperature linear fit equation is judged to be greater than or equal to the slope threshold, the cooling component power is reduced. If the absolute value of the slope of the temperature linear fitting equation is greater than or equal to the slope threshold, it indicates that the temperature variation trend is too large, and after a period of time, the temperature will jump out of the preset temperature range, so that the purpose of controlling the internal temperature of the first cavity 12 cannot be achieved. At this time, the power of the refrigeration component needs to be reduced, the temperature values at a plurality of moments within the preset time period of the current moment of the first cavity 12 are obtained in a return mode, and the temperature of the first cavity is monitored and adjusted in real time, so that the purpose of controlling the internal constant temperature of the refrigerator body 2 is achieved.
In step S20, when the first cavity temperature is judged to be higher than the highest temperature of the preset temperature range, the power of the refrigeration assembly is increased. If the first cavity temperature is higher than the highest temperature of the preset temperature range, the first cavity temperature is still higher than the highest temperature of the preset temperature range, the refrigeration efficiency is low, and at the moment, the power of the refrigeration assembly can be increased, so that the first cavity temperature can quickly reach the inside of the preset temperature range. Meanwhile, after the power of the refrigeration component is increased, the temperature values at a plurality of moments within the preset time period of the current moment of the first cavity 12 are returned, and the temperature of the first cavity is monitored and adjusted in real time, so that the purpose of controlling the internal constant temperature of the refrigerator body 2 is achieved.
In steps S10 to S20, the outdoor temperature is obtained and compared with the highest temperature of the preset temperature range, and if the outdoor temperature is judged to be higher than the highest temperature of the preset temperature range, it indicates that the inside of the refrigerator body 2 needs to be cooled, and the cooling component is started. In the process of refrigerating the inside of the refrigerator body 2, temperature values at a plurality of moments within a preset time period of the current moment of the first cavity 12 are obtained, and a temperature linear fitting equation and the current moment temperature of the first cavity 12 are sequentially calculated. And comparing the temperature of the first cavity with the highest temperature of a preset temperature range and the lowest temperature of the preset temperature range in sequence, and if the temperature of the first cavity is within the preset temperature range, judging whether the absolute value of the slope of the temperature linear fitting equation is smaller than a slope threshold value or not. If the absolute value of the slope of the temperature linear fitting equation is smaller than the slope threshold, stabilizing the power of the refrigeration assembly; if the absolute value of the slope of the temperature linear fitting equation is greater than or equal to the slope threshold, the power of the refrigeration assembly is reduced, and the change state of the internal temperature of the first cavity 12 is obtained again, so that the purpose of controlling the internal constant temperature of the refrigerator body 2 is achieved.
In this embodiment of the present invention, in order to control the temperature inside the refrigerator cabinet 2 more precisely, the power of the first heating assembly needs to be regulated and controlled in real time, and the control method can be specifically shown in fig. 5. Specifically, in fig. 5, the control method may include:
in step S30, the outdoor temperature is acquired. Wherein, the temperature sensor is adopted to monitor the temperature outside the refrigerator body 2 in real time.
In step S31, it is determined whether the outdoor temperature is less than the lowest temperature of the preset temperature range. Wherein, the preset temperature range which needs to be reached inside the refrigerator body 2 is adjusted according to the storage temperature range of the cosmetics which need to be placed. At this time, the outdoor temperature and the preset temperature range are judged, so that the first heating assembly 7 is driven to adjust the temperature inside the refrigerator body 2 to the preset temperature range.
In step S32, when it is judged that the outdoor temperature is less than the lowest temperature of the preset temperature range, the first heating assembly 7 is activated. If the outdoor temperature is lower than the highest temperature of the preset temperature range, it indicates that the external temperature is low, and the interior of the refrigerator body 2 needs to be heated, so that the first heating assembly 7 is started to raise the temperature of the interior of the refrigerator body 2.
In step S33, temperature values at a plurality of times within a preset time period of the current time of the first cavity 12 are obtained. The temperature inside the first cavity 12 is monitored in real time by using a temperature sensor, and a plurality of temperature values are acquired within a preset time period at the current moment.
In step S34, a linear fit equation of the temperature at the present time is calculated according to equation (1),
y＝kt+b，
arg mink，b LOSS， (1)
wherein y is a temperature value of the temperature linear fitting equation, k is a slope of the temperature linear fitting equation, b is a longitudinal intercept of the temperature linear fitting equation, LOSS is a sum of squares of residuals, n is a total number of acquisitions, t is 1, 2iIs the time of the i-th acquisition,
is tiLinear fit value of temperature over time, y (t)i) Is acquired tiTemperature value at time, argmink，bLOSS represents the value of k and b at which LOSS is a minimum.
In step S35, the first chamber temperature at the present time is calculated according to equation (2),
T＝ktT+b， (2)
wherein, tTIntermediate time, t, of a predetermined time period for the current timeaInitial time, t, of a predetermined time period for the current timebAnd T is the temperature of the first cavity at the current moment.
In step S36, it is determined whether the first cavity temperature is greater than or equal to the lowest temperature of the preset temperature range. Wherein, the calculated first cavity temperature is compared with the lowest temperature of the preset temperature range to determine whether the heating effect of the first heating assembly 7 reaches the expected state.
In step S37, when the first chamber temperature is determined to be greater than or equal to the lowest temperature of the preset temperature range, it is determined again whether the first chamber temperature is less than or equal to the highest temperature of the preset temperature range. If the temperature of the first cavity is greater than or equal to the lowest temperature of the preset temperature range, it indicates that the heating effect of the first heating assembly 7 is good, and the temperature inside the refrigerator body 2 gradually rises. In order to keep the temperature inside the refrigerator body 2 within the preset temperature range, it is necessary to determine again whether the temperature of the first cavity is less than or equal to the highest temperature of the preset temperature range.
In step S38, when it is determined that the first cavity temperature is less than or equal to the highest temperature of the preset temperature range, it is determined again whether the absolute value of the slope of the temperature linear fitting equation is less than the slope threshold. If the first cavity temperature is less than or equal to the highest temperature of the preset temperature range, the first cavity temperature is within the preset temperature range at the moment. In order to maintain the constant temperature state inside the refrigerator body 2 and reduce the temperature fluctuation inside the refrigerator body 2, the absolute value of the slope of the temperature linear fitting equation needs to be judged and controlled within the range of the slope threshold, so as to avoid the situation of overlarge temperature change.
In step S39, in the case where it is determined that the absolute value of the slope of the temperature linear fit equation is greater than or equal to the slope threshold value, the power of the first heating assembly 7 is reduced. If the absolute value of the slope of the temperature linear fitting equation is greater than or equal to the slope threshold, it indicates that the temperature variation trend is too large, and after a period of time, the temperature will jump out of the preset temperature range, so that the purpose of controlling the internal temperature of the first cavity 12 cannot be achieved. At this time, the power of the first heating assembly 7 needs to be reduced, the temperature values at a plurality of moments within the preset time period of the current moment of the first cavity 12 are obtained, and the temperature of the first cavity is monitored and adjusted in real time, so that the purpose of controlling the internal constant temperature of the refrigerator body 2 is achieved.
In step S40, when the first cavity temperature is determined to be lower than the lowest temperature of the preset temperature range, the power of the first heating assembly 7 is increased. If the first cavity temperature is lower than the lowest temperature of the preset temperature range, it indicates that the first cavity temperature is still below the lowest temperature of the preset temperature range, the heating efficiency is low, and at this time, the power of the first heating assembly 7 can be increased, so that the first cavity temperature quickly reaches the inside of the preset temperature range. Meanwhile, after the power of the first heating component 7 is increased, the temperature values at a plurality of moments within the preset time period of the current moment of the first cavity 12 are returned to be obtained, and the temperature of the first cavity is monitored and adjusted in real time so as to achieve the purpose of controlling the internal constant temperature of the refrigerator body 2.
In steps S30 to S40, the outdoor temperature is obtained and compared with the lowest temperature of the preset temperature range, and if the outdoor temperature is determined to be lower than the lowest temperature of the preset temperature range, it indicates that the interior of the refrigerator body 2 needs to be heated, and the first heating element 7 is activated. In the process of heating the inside of the refrigerator body 2, temperature values at a plurality of moments within a preset time period of the current moment of the first cavity 12 are obtained, and a temperature linear fitting equation and the current moment temperature of the first cavity 12 are sequentially calculated.
