[0002] Food aging is a process that improves the quality of meat. It allows meat to ferment and age naturally under a specific temperature and humidity environment, thereby producing a fresh and tender meaty taste and rich flavor and aroma. Among them, the aging process is divided into dry aging process and wet aging process. The dry aging process is suitable for livestock and poultry meat, which is conducive to producing unique flavors such as butter, nuts and barbecue; the wet aging process is suitable for aquatic seafood, which tends to maintain the tenderness and bright color of seafood.

[0078] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0079] The refrigerator provided in the embodiment of the present application is a refrigeration device, which at least includes a refrigeration system, a cooling system, a control system and a cabinet to achieve refrigeration and operation. Among them, the refrigeration system is used to produce a refrigeration effect, the cooling system is used to maintain a low temperature environment, the control system is used to control the temperature and humidity in the refrigerator, etc., and the cabinet is used to provide storage space. It can be understood that the refrigeration system, the cooling system, and the control system include specific components that can achieve the above functions.

[0080] In some embodiments, the refrigeration system includes a compressor, a condenser, an evaporator, and a throttling device. Among them, the compressor is used to compress the refrigerant gas, increase the pressure and temperature, and thus promote the flow of the refrigerant in the system. During the compression process, the refrigerant changes from a low-pressure and low-temperature gas to a high-pressure and high-temperature gas, thereby producing a refrigeration effect. The condenser is used to cool the high-temperature and high-pressure gas discharged from the compressor into a liquid state. The heat is released through the heat sink, and the refrigerant gas is converted into a liquid state, ready to enter the next step of the refrigeration cycle. The evaporator is used to absorb heat in the refrigeration system. The refrigerant evaporates from a liquid state to a gas state in the evaporator, absorbing heat from the surrounding environment, thereby achieving the purpose of lowering the temperature inside the refrigerator. The throttling device may include an expansion valve and a capillary tube, which are used to adjust the flow rate of the refrigerant, reduce its pressure, and make it become a low-temperature and low-pressure gas-liquid mixed state, ready to enter the evaporator.

[0081] In some embodiments, the cooling system includes a fan connected to the evaporator. The fan circulates air in the compartments, such as the freezer and refrigerator, to transfer heat to the evaporator, helping to maintain a low temperature environment inside the refrigerator.

[0082] It should be noted that the above example is merely a simple division of the functions of the refrigerator and does not constitute a limitation on the specific structure of the refrigerator in the embodiment of the present application.

[0083] In some refrigerators, a aging area can be set up in the cold storage room for food aging. Food aging is a process to improve the quality of meat. Meat is naturally fermented and aged under a specific temperature and humidity environment, so as to produce a fresh and tender meat taste and rich flavor and aroma. Among them, the aging process is divided into dry aging process and wet aging process. The dry aging process is suitable for livestock and poultry meat, which is conducive to producing the unique flavor of butter, nuts and barbecue; the wet aging process is suitable for aquatic seafood, which tends to maintain the tenderness and bright color of seafood. During the food aging process, food aging can be achieved by controlling the temperature, humidity and wind speed in the aging area. For example, the real-time weight of the air-dried ingredients is monitored by a gravity sensor in the aging room, and the real-time juice loss rate of the air-dried food is calculated based on the real-time weight and the initial weight of the air-dried food. The wind speed of the wind speed regulating device is adjusted according to the comparison result of the real-time juice loss rate and the preset loss rate threshold, and the humidity in the aging room is controlled by setting a humidifying device. However, ordinary refrigerators usually cannot provide the required humidity control, and humidity control is essential for the drying and flavor formation of meat.

[0084] Therefore, in order to solve the problem of humidity control of food ingredients in the refrigerator, see Figure 1 Some embodiments of the present application provide a food cooking method, comprising:

[0085] S101: Obtaining the initial weight of the food to be cooked;

[0086] S102: Control the electric damper to open, and deliver cold air to the ripening drawer to reduce the temperature in the ripening drawer to a first temperature range;

[0087] S103: Control the variable frequency fan to run at a first speed;

[0088] S104: Obtaining a first weight of the food to be cooked;

[0089] Among them, after the user puts the food to be cooked into the cooking drawer of the refrigerator, the cooking function of the refrigerator can be manually turned on. When the refrigerator receives the user's instruction to turn on the cooking function of the refrigerator, the refrigerator controller can control the electric damper to open, supply cold air to the cooking drawer, and reduce the temperature in the cooking drawer to the first temperature range. At the same time, the variable frequency fan is controlled to run at the first speed. At this time, the food to be cooked is in the first stage of cooking.

[0090] Specifically, when the user puts the food to be cooked into the cooking chamber, the electric damper opens and delivers cold air to reduce the temperature in the cooking chamber to a first temperature range of -8°C to -2°C. When the temperature in the cooking drawer is in the first temperature range, the variable frequency fan is started and controlled to run at a first speed of 3000-3500r / min.

[0091] When the food to be cooked is placed in the cooking drawer, the initial weight of the food to be cooked can be recorded. When the temperature in the cooking drawer is within the first temperature range and the speed of the variable frequency fan is at the first speed, the first weight of the food to be cooked can be obtained in real time. It can be understood that as the moisture in the food gradually loses, the first weight of the food to be cooked will gradually decrease.

[0092] S105: Calculating a weight loss rate of the first food material according to the initial weight and the first weight.

[0093] Calculating the weight loss rate of the first food material according to the initial weight and the first weight specifically includes:

[0094] calculating the difference between the initial weight and the first weight;

[0095] According to the difference, the ratio of the difference to the initial weight is calculated to obtain the weight loss rate of the first food.

[0096] Specifically, the weight loss rate of the first food material is obtained by calculating the difference between the initial weight and the first weight and the ratio of the difference to the initial weight. The formula for the weight loss rate of the first food material is:

[0097]

[0098] Wherein, V is the weight loss rate of the first food material, M0 is the initial weight, and M1 is the first weight.

[0099] S106: Obtaining the surface moisture content of the food to be cooked.

[0100] Among them, the surface moisture content of the food to be cooked can be detected and obtained through a hyperspectral recognition device.

[0101] S107: If the weight loss rate of the first food is within a first preset weight loss rate range, and / or the surface moisture content is within a first preset moisture content range, the electric damper and the variable frequency fan are controlled to operate in a first preset mode.

[0102] The first preset mode is that the electric damper and the variable frequency fan operate alternately in a moisturizing mode and an air drying mode. The first preset weight loss rate range is 5-10%, and the first preset moisture content range is 60-65%. When the weight loss rate of the first food is within the first preset weight loss rate range and / or the surface moisture content is within the first preset moisture content range, it indicates that the first ripening stage of the food to be cooked is over, and the food to be cooked enters the second ripening stage.

[0103] In the second stage of ripening, the electric damper and variable frequency fan will operate alternately in moisturizing mode and air-drying mode.

[0104] Among them, controlling the electric damper and the variable frequency fan to operate in the moisturizing mode includes:

[0105] Controlling the electric damper to open intermittently so that the temperature in the ripening drawer is in the second temperature range;

[0106] The variable frequency fan is controlled to run at a second speed for a first preset time.

[0107] Specifically, when the electric damper and the variable frequency fan are controlled to operate in the moisturizing mode, the electric damper is intermittently opened to maintain the temperature of the aging drawer in the second temperature range of -2°C to 2°C, and the variable frequency fan is operated at the second speed of 2500-2000r / min, and when the moisturizing time reaches the first preset time, the moisturizing mode is terminated. The first preset time is 1-3 days.

[0108] When the moisturizing mode is switched to the air-drying mode, the electric damper and the variable frequency fan are controlled to operate in the air-drying mode including:

[0109] Controlling the electric damper to open intermittently so that the temperature in the ripening drawer is in the second temperature range;

[0110] Control the variable frequency fan to run at a first speed and start timing;

[0111] Calculating characteristic parameters of water evaporation of the food to be cooked within a second preset time;

[0112] If the water evaporation characteristic parameter is within the preset range, the temperature in the ripening drawer is controlled to be in the second temperature range and the variable frequency fan is operated at the first speed;

[0113] If the water evaporation characteristic parameter is not within the preset range, the temperature in the ripening drawer is controlled to be in the third temperature range.

[0114] Specifically, when the electric damper and the variable frequency fan are running in the air-drying mode, the temperature in the ripening drawer is kept constant, the speed of the variable frequency fan is adjusted to the first speed, and counting is started. Within the second preset time, the characteristic parameters of water evaporation are calculated. Among them, the second preset time is 0.5-1.5 days. The characteristic parameters of water evaporation are weight loss rate and surface water evaporator. When the weight loss rate and / or the surface water content decrease rate are within the preset range, wherein the preset range is 1-2%, and the surface water content decrease rate is 5-10%, the temperature in the ripening drawer is controlled in the second preset interval, and the variable frequency fan runs at the first speed.

[0115] When the weight loss rate and / or the surface moisture content decrease rate is less than the minimum value of the preset range, that is, the moisture evaporation characteristic parameter is not within the preset range, the damper is opened to adjust the temperature in the aging drawer to the third temperature range, wherein the third temperature range is -4°C to 0°C. The speed of the variable frequency fan remains unchanged.

[0116] When the weight loss rate and / or the rate of decrease of surface moisture content is within the preset range, the electric damper and the variable frequency fan can be controlled to operate in the moisturizing mode, and after operating in the moisturizing mode for the first preset time, the air drying mode is adjusted to operate. The moisturizing mode and the air drying mode are alternately operated to further air dry the food to be cooked.

[0117] It can be understood that when calculating the weight loss rate, the speed of the variable frequency fan is adjusted to the first speed, and when counting begins, the weight of the food to be cooked is the initial weight. After the second preset time, the difference between the current weight of the food to be cooked and the initial weight, and the ratio of the difference to the initial weight is the weight loss rate, that is, the weight detected at the end of the moisturizing mode is the initial weight.

[0118] S108: Obtaining a second weight of the food to be cooked, and calculating a weight loss rate of the second food according to the second weight;

[0119] S109: If the weight loss rate of the second food is within the second preset weight loss rate range, and / or the surface moisture content is within the second preset moisture content range, the electric damper and the variable frequency fan are controlled to operate in a second preset mode.

[0120] Among them, the second preset mode is that the electric damper is intermittently opened, so that the temperature of the ripening drawer is in the second temperature range, and the variable frequency fan runs at the third speed. The calculation method of the weight loss rate of the second ingredient is the same as that of the first ingredient. The second preset weight loss rate range is 15-20%, and the second preset moisture content range is 50-60%. When the weight loss rate of the second ingredient is within the second preset weight loss rate range, and / or the surface moisture content is within the second preset moisture content range, it means that the second ripening stage of the ingredient to be ripened is over, and the ingredient to be ripened enters the third ripening stage.

[0121] In the third ripening stage, the electric damper is opened intermittently, so that the temperature of the ripening drawer is in the second temperature range, and the variable frequency fan runs at the third speed.

[0122] Specifically, the electric damper is controlled to open intermittently to maintain the temperature of the aging drawer in the second temperature range of -2°C to 2°C, and at the same time, the variable frequency fan is operated at a third speed of 1500-2000r / min.

[0123] S110: Obtaining a third weight of the food to be cooked, and calculating a weight loss rate of the third food according to the third weight;

[0124] S111: If the weight loss rate of the third food ingredient is within a third preset weight loss rate range, and / or the surface moisture content is within a third preset moisture content range, it is determined that the food ingredient to be cooked is fully cooked.

[0125] The weight loss rate of the third food material is in the range of 20-25%, and the third preset moisture content is in the range of 40-50%. That is, if the weight loss rate of the third food material is in the range of 20-25%, and / or the surface moisture content is in the range of 40-50%, it is determined that the food material to be cooked is cooked.

[0126] The present application calculates the moisture content and weight loss rate of the food to be cooked, and matches the appropriate variable frequency fan speed and cooking drawer temperature at different cooking stages to ensure the cooking effect of the food to be cooked. In addition, in the food cooking method of the present application embodiment, there is no need to control the humidity in the cooking drawer, so as to solve the problem of needing to control the humidity during the cooking process of refrigerator food.

[0127] During the ripening process of the food to be cooked, it is also necessary to sterilize the ripening chamber to ensure the freshness of the food. At the same time, since the surface of the food to be cooked will gradually dry during the ripening process and there are fewer microorganisms, the sterilization frequency can be adjusted according to the ripening stage of the food to be cooked to reduce the power consumption of the refrigerator.

[0128] Therefore, in some embodiments, the food cooking method further comprises:

[0129] If the variable frequency fan is running at the first speed, the ion generator is turned on for a third preset time at a fourth preset time interval;

[0130] If the electric damper and the variable frequency fan are operated in the moisturizing mode, the ion generator is turned on for a fifth preset time at a sixth preset time interval;

[0131] If the electric damper and the variable frequency blower are operated in the air-drying mode, the ion generator is turned on for a third preset time at a fourth preset time interval;

[0132] If the variable frequency fan runs at the third speed, the ion generator is turned on for a fifth preset time at a sixth preset time interval.

[0133] Specifically, when the variable frequency fan runs at the first speed, that is, the food is in the first stage of cooking, at this time, the ion generator is turned on for the third preset time at a fourth preset time interval, wherein the fourth preset time is 5-10 minutes, and the third preset time is 3-5 seconds, that is, the ion generator is turned on for 2-5 seconds each time and stopped for 5-10 minutes.

[0134] When the electric damper and the variable frequency fan are running in the moisturizing mode, that is, the food is in the second stage of ripening, the ion generator is turned on for the fifth preset time at the sixth preset time interval. Among them, the fifth preset time is 1-3s, and the sixth preset time is 0-5min. That is, the ion generator is turned on for 1-3s each time and stopped for 0-5min.

[0135] When the electric damper and the variable frequency fan are running in the air-drying mode, that is, the food is in the second stage of ripening, the ion generator is turned on for the third preset time at a fourth preset time interval; wherein, the fourth preset time is 5-10 minutes, and the third preset time is 3-5 seconds, that is, the ion generator is turned on for 2-5 seconds each time and stopped for 5-10 minutes.

[0136] When the variable frequency fan runs at the third speed, that is, the food is in the third stage of cooking, at this time, the ion generator is turned on for the fifth preset time at the sixth preset time interval. Among them, the fifth preset time is 1-3s, and the sixth preset time is 0-5min. That is, the ion generator is turned on for 1-3s each time and stopped for 0-5min.

[0137] By setting up an ion generator, the ion generator sterilizes the microorganisms in the cold air when the damper is opened to prevent contamination of the food to be cooked, which affects the cooking effect and food safety. The sterilization logic is different in different stages. When the speed of the variable frequency fan increases, the wind speed in the drawer increases, which increases the working time of the ion generator.

[0138] In an embodiment of the present application, a wind speed sensor may also be provided in the ripening drawer. At different stages of food ripening, the speed of the variable frequency fan may be adjusted by controlling the wind speed in the ripening drawer.

[0139] For example, in the first stage of ripening, the variable frequency fan in the air duct is turned on, so that the wind speed in the ripening drawer reaches 1.0-1.5m / s.

[0140] In the second stage of ripening, when the electric fan and the variable frequency fan operate in moisturizing mode, the wind speed in the ripening drawer is 0-0.5m / s, thereby adjusting the speed of the variable frequency fan; when the electric fan and the variable frequency fan operate in air-drying mode, the wind speed in the ripening drawer is adjusted to 1.0-1.5m / s.

[0141] In the third stage of ripening, the wind speed in the ripening drawer is 0.5-1.0m / s, so the wind speed of the variable frequency fan is adjusted.
