Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a fruit and vegetable preservation refrigerator. Background Technology

[0002] Temperature affects the release rate of volatile flavor compounds. Higher temperatures generally accelerate the release of volatile compounds, making the aroma of fruits and vegetables more intense, but they can also lead to the excessive volatilization of certain flavor compounds, affecting the flavor balance. For example, refrigerated storage (12.5°C) leads to a reduction in the total volatile compounds in tomatoes. Temperature affects the metabolism of sugars and organic acids in fruits and vegetables, thus affecting their sweetness and acidity. For example, low temperatures may inhibit sugar breakdown, maintaining the sweetness of fruits and vegetables, while temperature fluctuations may cause changes in the sugar-acid ratio, affecting the harmony of flavors. For example, late-season navel oranges stored at 5°C, 15°C, 20°C, and 25°C show a decrease in flavor and an increase in off-flavors as the temperature rises. Temperature also affects the growth and metabolic activities of microorganisms, thus influencing the flavor of fruits and vegetables.

[0003] For fruit and vegetable preservation, current technologies mainly employ low-temperature storage strategies. By lowering the temperature, the respiration rate and microbial reproduction rate of fruits and vegetables are slowed down, thereby extending the shelf life. For climacteric fruits and vegetables, although low-temperature storage can control pathogen activity to some extent, prolonged low temperatures can easily lead to chilling injury, affecting the normal ripening process and causing a decline in quality.

[0004] Climax fruits and vegetables are highly susceptible to chilling injury under prolonged low temperatures, leading to problems such as browning of the flesh, tissue fibrosis, loss of flavor, and rotting. While low-temperature storage can control pathogen activity, it has a significant impact on the quality of climax fruits and vegetables, especially those in the green-ripe and early-ripe stages, where chilling injury can prevent them from maturing properly. Furthermore, the current difficulty in real-time monitoring and assessment of the preservation effects on climax fruits and vegetables makes them prone to rotting and chilling injury during storage.

It is worth noting that the method for acquiring the temperature within the fruit and vegetable preservation zone is not limited in this embodiment.

[0080] Based on the preservation temperature, calculate the integral average temperature and temperature fluctuation range within the fruit and vegetable preservation zone; the integral average temperature experienced by the fruits and vegetables to be preserved during storage is T(°C) = (T1 + T2 + ... + T...). n ) / n, where T1, T2, ..., T n This represents the temperature records during the storage of fruits and vegetables to be preserved, where n is the number of temperature records, and n≥100.

[0081] Based on the integral average temperature and the temperature fluctuation range, the fruit and vegetable flavor results are obtained and sent to the display panel 11 for display, such as... Figure 3 As shown.

[0082] In this embodiment, the types of fruits and vegetables include: berries and melons; the freshness of the fruits and vegetables includes: fresh and relatively fresh; the flavor results of the fruits and vegetables include: optimal consumption period, consumption as soon as possible, and consumption with caution; wherein, the reasonable storage temperature for berries is 1°C; and the reasonable storage temperature for melons is 5°C.

[0083] like Figure 6 The diagram shown is a flowchart for the use of berry-type fruits in this application.

[0084] The temperature control module 2 is further configured as follows:

[0085] When the confirmed information is berries and fresh, the fruit and vegetable preservation zone is controlled at 1℃; if the integral average temperature is greater than or equal to 0.5℃ and less than or equal to 1.5℃, and the temperature fluctuation range is less than or equal to 0.5℃, the preservation time of the fruit and vegetables to be preserved is determined; if the preservation time is within the first to the 21st day, the fruit and vegetable flavor result is the optimal consumption period; if the preservation time is within the 21st to the 28th day, the fruit and vegetable flavor result is to be consumed as soon as possible; if the preservation time is more than 28 days, the fruit and vegetable flavor result is to be consumed with caution.

[0086] Specifically, when the temperature control module 2 receives confirmation from the user that the berries are fresh, it maintains the fruit and vegetable preservation area at 1°C, initiates temperature control, and monitors the integral average temperature and temperature fluctuation range. When the integral average temperature is 0.5°C ≤ T ≤ 1.5°C and ΔT ≤ 0.5°C, the temperature control module 2 outputs "best before consumption" for the berries within 0 to 21 days, "consume as soon as possible" for the berries within 21 to 28 days, and "consume with caution" for the berries after 28 days.

When the integral average temperature is 0.5°C ≤ T ≤ 1.5°C, and 0.5°C < ΔT ≤ 2°C, the temperature control module 2 outputs "best time to eat" for the berries within 0 to 14 days, "eat as soon as possible" for the berries within 14 to 21 days, and "eat with caution" for the berries after 21 days.

[0090] In this embodiment, the temperature control module 2 is further configured as follows:

[0091] When the confirmed information indicates that the fruit is a berry and fresh, the fruit and vegetable preservation zone is controlled at 1°C. If the average temperature is greater than or equal to 0.5°C and less than or equal to 1.5°C, and the temperature fluctuation is greater than 2°C, the preservation time of the fruit and vegetable to be preserved is determined.

If the preservation time is within the seventh to fourteenth day, the fruit and vegetable flavor result is to be consumed as soon as possible. If the preservation time is more than 14 days, the fruit and vegetable flavor result is to be consumed with caution. If the average temperature is greater than 1.5°C or less than 0.5°C, the fruit and vegetable flavor result is to be consumed as soon as possible.

When the integrated average temperature is 0.5°C ≤ T ≤ 1.5°C, and ΔT > 2°C, the temperature control module 2 outputs "Best Time to Eat" for the berries within 0 to 7 days, "Eat as Soon as Possible" for the berries within 7 to 14 days, and "Eat with Caution" for the berries after 14 days. When the integrated average temperature T > 1.5°C or T < 0.5°C, the temperature control module 2 outputs "Eat as Soon as Possible."

[0093] In this embodiment, the temperature control module 2 is further configured as follows:

[0094] When the confirmed information indicates that the fruit is a berry or relatively fresh, the fruit and vegetable preservation zone should be kept at 1°C and the fruit and vegetable flavor result should be consumed as soon as possible.

[0095] Specifically, when the temperature control module 2 receives confirmation from the user that the fruit and vegetable preservation area is "relatively fresh" and that the fruit and vegetable is "to be consumed as soon as possible", the temperature control module 2 maintains the fruit and vegetable preservation area at 1°C and outputs "consume the fruit as soon as possible".

[0096] like Figure 5 The diagram shown is a flowchart of the preservation process for fruits and vegetables in this application.

[0097] In this embodiment, the temperature control module 2 is further configured as follows:

[0098] When the confirmed information is fruits and vegetables and they are fresh, the fruit and vegetable preservation zone is controlled at 5℃; if the integral average temperature is greater than or equal to 4℃ and less than or equal to 6℃, and the temperature fluctuation range is less than or equal to 1.5℃, the preservation time of the fruits and vegetables to be preserved is determined; if the preservation time is within the first to the 21st day, the flavor result of the fruits and vegetables is the best time to eat; if the preservation time is within the 21st to the 28th day, the flavor result of the fruits and vegetables is to be eaten as soon as possible; if the preservation time is more than 28 days, the flavor result of the fruits and vegetables is to be eaten with caution.

[0099] Specifically, when the temperature control module 2 receives confirmation from the user that the "fruits and vegetables" are "fresh," it maintains the fruit and vegetable preservation area at 5°C, initiates temperature control, and monitors the integral average temperature and temperature fluctuation range. When the integral average temperature is 4°C ≤ T ≤ 6°C and ΔT ≤ 1.5°C, the temperature control module 2 outputs "best time to eat" for fruits and vegetables within 0 to 21 days, "eat as soon as possible" for fruits and vegetables within 21 to 28 days, and "eat with caution" for fruits and vegetables after 28 days.

[0100] In this embodiment, the temperature control module 2 is further configured as follows:

[0102] Specifically, when the temperature control module 2 receives confirmation from the user that the "fruits and vegetables" are "fresh," it maintains the fruit and vegetable preservation area at 5°C, initiates temperature control, and monitors the integral average temperature and temperature fluctuation range. When the integral average temperature is 4°C ≤ T ≤ 6°C and 1.5°C < ΔT ≤ 3°C, the temperature control module 2 outputs "best time to eat" for fruits and vegetables within 0 to 14 days, "eat as soon as possible" for fruits and vegetables within 14 to 21 days, and "eat with caution" for fruits and vegetables after 21 days.

[0103] In this embodiment, the temperature control module 2 is further configured to: when the confirmed information is melons and vegetables and fresh, control the fruit and vegetable preservation zone at 5℃; if the integral average temperature is greater than or equal to 4℃ and less than or equal to 6℃, and the temperature fluctuation range is greater than 3℃, determine the preservation time of the fruits and vegetables to be preserved; if the preservation time is within the first to seventh day, the fruit and vegetable flavor result is the optimal consumption period; if the preservation time is within the seventh to fourteenth day, the fruit and vegetable flavor result is to be consumed as soon as possible; if the preservation time is more than 14 days, the fruit and vegetable flavor result is to be consumed with caution; if the integral average temperature is greater than 6℃ or less than 4℃, the fruit and vegetable flavor result is to be consumed as soon as possible; when the confirmed information is melons and vegetables and relatively fresh, control the fruit and vegetable preservation zone at 5℃ and the fruit and vegetable flavor result is to be consumed as soon as possible.

[0104] Specifically, when the temperature control module 2 receives confirmation from the user that the vegetables are "fruits and vegetables" and "fresh," it maintains the fruit and vegetable preservation area at 5℃, initiates temperature control, and monitors the integrated average temperature and temperature fluctuation range. When the integrated average temperature is 4℃≤T≤6℃ and ΔT>3℃, the temperature control module 2 outputs "best time to eat" for fruits and vegetables within 0 to 7 days, "eat as soon as possible" for fruits and vegetables within 7 to 14 days, and "eat with caution" for fruits and vegetables after 14 days. When the integrated average temperature is T>6℃ or T<4℃, the temperature control module 2 outputs "eat as soon as possible." When the intelligent system receives confirmation from the user that the vegetables are "fruits and vegetables" and "relatively fresh," it maintains the fruit and vegetable preservation area at 5℃, and the temperature control module 2 outputs "eat as soon as possible."

[0105] In this embodiment, the temperature control module 2 is further configured as follows:

[0106] If no confirmation is received, the fruit and vegetable preservation area will be kept at 3°C ​​and the fruit and vegetable flavor results will be consumed as soon as possible.

[0107] Specifically, when the temperature control module 2 does not receive confirmation from the user regarding the type of fruit and vegetables and their freshness, the temperature control module 2 will maintain the fruit and vegetable preservation area at 3°C ​​and output "Eat as soon as possible".

[0108] In this embodiment, the refrigerator further includes:

[0109] Data acquisition module 3 is communicatively connected to the display panel 11 and the temperature control module 2; the data acquisition module 3 is located within the fruit and vegetable preservation area, and is configured as follows:

[0110] Images are collected within the fruit and vegetable preservation area; based on the images, it is determined whether there are fruits and vegetables to be preserved in the fruit and vegetable preservation area; the presence of fruits and vegetables in the fruit and vegetable preservation area can be confirmed by the images within the area.

[0111] If so, the display panel 11 is controlled to display the control interface, and the temperature control module 2 is controlled to record the preservation time of the fruits and vegetables to be preserved; the control interface is used to display the confirmation information, such as... Figure 4As shown; when the display time on the control interface exceeds the preset time, the fruit and vegetable preservation zone will be controlled at 3℃ and the fruit and vegetable flavor result will be set to be consumed as soon as possible. If the user forgets to enter confirmation information after the fruit and vegetable is placed in the fruit and vegetable preservation zone, and the display time on the control interface exceeds the preset time (e.g., 1 minute), the fruit and vegetable preservation zone will be controlled at an average temperature of 3℃, which is the average of the reasonable storage temperature for berries (1℃) and melons and vegetables (5℃). This will prevent the fruit and vegetable placed in the fruit and vegetable preservation zone from spoiling, and a "consume as soon as possible" indicator will remind the user to enter confirmation information as soon as possible.

[0112] This application provides a fruit and vegetable preservation refrigerator. By having the user confirm whether the fruit is a "berry" or a "melon and vegetable," the refrigerator provides appropriate storage temperature conditions and sends this information to the temperature control system for temperature control. The user also confirms the freshness status as "fresh" or "relatively fresh." While this method increases user intervention, the refrigerator's intelligent system obtains food information accurately and at a low cost. Because berries are perishable and sensitive to ambient temperature, this application provides precise temperature control for "berries" and, based on the different changes in their shelf life, aroma, and sweetness under varying temperature conditions, prompts the user to consume them at the appropriate time. Since melons and vegetables undergo a ripening process, although low temperatures can extend their shelf life, they are detrimental to the volatilization of aroma compounds and the maturation of flavor; high temperatures are beneficial for the volatilization of aroma compounds and the improvement of flavor, but shorten their shelf life. This application provides appropriate storage temperatures for "melon and vegetable" and, based on the different changes in their shelf life, aroma, and sweetness under varying temperature conditions, prompts the user to consume them at the appropriate time. By detecting and analyzing the decay rate, aroma substances, and sweetness substances of fresh "berries" or "melons and vegetables" under different temperature fluctuations, the optimal consumption period of "berries" or "melons and vegetables" is determined and the refrigerator's intelligent system provides notifications to the user.

[0113] This application provides a fruit and vegetable preservation refrigerator, as shown in Example 1 below:

[0114] When fresh blueberries are stored in the fruit and vegetable preservation refrigerator provided in this application, the user confirms "berries" and "fresh." The temperature control module 2 sends a "1℃" preservation request to the fruit and vegetable preservation zone. The temperature control module 2 analyzes the integral average temperature T and temperature fluctuation range ΔT of the fruit and vegetable preservation zone. When the integral average temperature is 0.5℃≤T≤1.5℃ and ΔT≤0.5℃, the temperature control module 2 outputs "best time to eat" for berries within 0 to 21 days, indicating "high values ​​of aldehydes (representing aroma), high values ​​of alcohols (representing sweetness), and high values ​​of olefins (representing fruit aroma)." Within 21 to 28 days, the temperature control module 2 outputs "eat as soon as possible" for berries, indicating "the value of aldehydes (representing aroma) gradually decreases, the value of alcohols (representing sweetness) is high, and the value of olefins (representing fruit aroma) gradually decreases." After 28 days, the temperature control module 2 outputs "eat with caution" for berries, indicating "the value of aldehydes (representing aroma) decreases rapidly, the value of alcohols (representing sweetness) gradually decreases, and the value of olefins (representing fruit aroma) decreases rapidly."

[0115] This application provides a fruit and vegetable preservation refrigerator, as shown in Embodiment 2 below:

[0116] When fresh tomatoes are stored in the fruit and vegetable preservation refrigerator provided in this application, the user confirms "fruits and vegetables" and "fresh." The temperature control module 2 sends a "5℃" preservation request to the fruit and vegetable preservation zone. The temperature control module 2 analyzes the integral average temperature T and temperature fluctuation range ΔT of the fruit and vegetable preservation zone. When the integral average temperature is 4℃≤T≤6℃ and 1.5℃<ΔT≤3℃, the temperature control module 2 outputs "best time to eat" for fruits and vegetables within 0 to 14 days, indicating "high values ​​of aldehydes (representing aroma), high values ​​of alcohols (representing sweetness), and high values ​​of esters (representing fruit aroma). Within 14 to 21 days, the temperature control module 2 outputs "eat as soon as possible" for fruits and vegetables, indicating "gradual decrease in aldehydes (representing aroma), high values ​​of alcohols (representing sweetness), and gradual decrease in esters (representing fruit aroma). After 21 days, the temperature control module 2 outputs "eat with caution" for fruits and vegetables, indicating "rapid decrease in aldehydes (representing aroma), gradual decrease in alcohols (representing sweetness), and rapid decrease in esters (representing fruit aroma)."
