More seriously, they may be infected by microorganisms such as mold and bacteria and cause rot. Studies have shown that most fruits and vegetables can achieve good preservation effects when the storage temperature is 2 to 4 degrees and the temperature fluctuation is less than ±1°C.

DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] In the home, the refrigerator is one of the important means of preserving food. Fruits and vegetables are highly seasonal and have regional restrictions. Fruits and vegetables are usually stored in the refrigerator's cold storage area for preservation, but different temperatures and temperature fluctuations will have a huge impact on the quality of fruits and vegetables. Improper storage temperature may cause the quality of fruits and vegetables to deteriorate rapidly, such as loss of nutrients or evaporation of water. More seriously, they may be infected by microorganisms such as mold and bacteria and cause decay. Studies have shown that for most fruits and vegetables, when the storage temperature is 2 to 4 degrees, the temperature fluctuation is less than ±1°C, and a good preservation effect can be obtained. Therefore, in order to solve the problem of long-term preservation of fruits and vegetables, strict temperature control requirements are put forward for the area where fruits and vegetables are stored in the refrigerator;

[0062] In current refrigerators, although the cold storage and fresh-keeping area is divided into different compartments, including a fruit and vegetable preservation compartment, the temperature control logic is the same as that of the entire cold storage area, resulting in a larger temperature range of between 1 and 10°C, and large fluctuations, far exceeding ±1°C.

[0063] The present application provides a method for controlling a refrigerator, wherein the refrigerator comprises a temperature measuring device and a weight detecting device, wherein the temperature measuring device is located at a preset temperature measuring position in the refrigerator, and the weight detecting device is located at a preset weight measuring position in the refrigerator. Figure 1 , the refrigerator control method includes steps S101 to S107.

[0064] In step S101, current temperature detection data, current weight detection data and current operation status information are obtained.

[0068] In one possible implementation, Figure 2 The temperature measuring device is shown to be located at a preset temperature measuring position in the refrigerator. The temperature measuring device includes a temperature sensing module and a temperature measuring module. The temperature measuring module is embedded in a preset temperature measuring position of the refrigerator housing near the storage device, and the temperature sensing module is arranged at a preset temperature sensing position of the storage device. The preset temperature sensing position is within the detection range of the temperature measuring module.

[0069] In a possible implementation, the temperature measuring device is an infrared temperature measuring module, and the temperature sensing device is a metal temperature sensing plate. Specifically, the infrared temperature measuring module is an infrared sensor, and a metal temperature sensing plate sprayed with a coating with an emissivity of 0.95 that can quickly sense temperature changes is placed at the same horizontal position on the same side of the infrared sensor. The metal temperature sensing plate is installed and connected in the middle area between one side and the bottom of the drawer, representing the temperature of this fruit and vegetable preservation compartment.

[0070] In one possible implementation, Figure 2 It is shown that the weight detection device is located at a preset weight measuring position in the refrigerator.

[0071] In one possible implementation, Figure 2 It is shown that a computing control unit MCU (Microcontroller Unit) and the door state detection are integrated on the power board of the refrigerator, and the computing control unit is electrically connected to the door state detection device, the temperature measuring device, the weight detection device and the refrigeration system respectively.

[0072] In a possible implementation, a refrigeration system of a refrigerator includes a variable frequency compressor, an evaporator, a fan, and an air door and vent.

[0073] In one possible implementation, Figure 2 It is shown that the door state detection device is used to detect the opening and closing state of the door of the refrigerator to obtain the current operating state information.

[0074] In one possible implementation, Figure 2 It is shown that a refrigerator shell near the fruit and vegetable preservation compartment is provided with a refrigeration system, the refrigeration system includes an evaporator and a fan, and the refrigeration system is used to refrigerate the fruit and vegetable preservation compartment according to the current refrigeration control data.

[0075] In a possible implementation, for the fruit and vegetable fresh-keeping compartment, a refrigeration system includes a separate evaporator, a fan, and an air outlet, which can independently refrigerate the fruit and vegetable fresh-keeping compartment in the refrigerated area.

[0076] In a possible implementation, the current temperature detection data is obtained by the temperature measuring device detecting the temperature of the environment in the refrigerator at the current time.

[0077] In a possible implementation, the current weight detection data is obtained by the weight detection device performing weight detection on the storage object in the refrigerator at the current time.

[0078] In a possible implementation, the current operating status information represents an opening or closing status of a door of the refrigerator.

[0079] In step S103, according to the current operating state information, a refrigeration capacity analysis is performed based on the current temperature detection data and the current weight detection data to obtain a current refrigeration capacity analysis result.

[0080] In a possible implementation, the current operating state information includes a first operating state and a second operating state, the first operating state indicating that the operating time after the door body is closed is greater than a first preset time, and the second operating state indicating that the door body is in an open state.

[0083] When the current operating status information is the second operating status, the door opening time from the time the door is opened to the time it is closed and the ambient temperature around the refrigerator are obtained, and ventilation and refrigeration analysis is performed based on the door opening time, the ambient temperature, the current temperature detection data, the current weight detection data and the preset temperature threshold to obtain a ventilation and refrigeration analysis result, and the ventilation and refrigeration analysis result is determined to be the current refrigeration analysis result.

[0084] In a possible implementation, the precise temperature control target of the fruit and vegetable preservation compartment is: to control the temperature of the compartment at Tb℃ (T is any one of 2 to 4℃), with a fluctuation range of ±1℃; the refrigeration temperature control logic of the fruit and vegetable compartment is divided into two control strategies, corresponding to different user refrigerator usage situations.

[0085] In a possible implementation, the first operating state indicates that the operating time after the door is closed is greater than a first preset time. Specifically, after the refrigerator has been running smoothly for n hours since the door was last opened, the value range of n is 4 to 6 (hours).

[0086] In a possible implementation, when the current operating state information is the first operating state, when the temperature detected by the infrared sensor is greater than or equal to Tb+0.5°C, the required cooling capacity is calculated according to the current total weight of fruits and vegetables and the current temperature in the fruit and vegetable fresh-keeping room, and then an application is made to start the compressor, and the air volume V of the fan can be obtained according to the required cooling capacity. Specifically, the value of Tb is any one of 2 to 4°C.

[0087] In a possible implementation, the preset temperature threshold is Tb.

[0088] In a possible implementation, the current total weight of fruits and vegetables is the current weight detection data, and the current temperature in the fruit and vegetable fresh-keeping room is the current temperature detection data.

The required refrigeration capacity is recalculated based on the weight of the new fruits and vegetables, the door opening time and the ambient temperature, and the current temperature of the fruit and vegetable preservation compartment, and then the refrigeration system is turned on based on the required refrigeration capacity.

[0091] In a possible implementation, the weight of the newly placed fruits and vegetables is the difference between the current weight detection data and the historical weight detection data.

[0092] In this implementation, the corresponding temperature control logic is determined according to different operating states, and the refrigeration capacity is estimated by combining weight and temperature, thereby improving the accuracy of refrigerator temperature control.

[0095] In the case where the temperature comparison result indicates that the difference between the current temperature detection data and the preset temperature threshold is less than or equal to the preset difference, determining the stable refrigeration analysis result as that the current environment in the refrigerator meets the preset target condition;

[0096] When the temperature comparison result indicates that the difference between the current temperature detection data and the preset temperature threshold is greater than the preset difference, a steady cooling capacity calculation is performed based on the current temperature detection data, the current weight detection data and the preset temperature threshold to obtain the steady cooling capacity, and the steady cooling capacity is determined as the steady cooling analysis result.

[0097] In a possible implementation, cooling capacity is the abbreviation of heat flow in the refrigerator refrigeration compartment. After the required heat flow in the fruit and vegetable preservation compartment is determined, the cooling capacity required to maintain a specific temperature for a period of time can be determined.

[0098] In a possible implementation, the steady cooling capacity is obtained by calculating the heat flow QS.

[0099] In a possible implementation, the heat flow QS of the fruit and vegetable preservation compartment includes two parts: operating ventilation heat Q1 and fruit and vegetable heat Q2, QS=Q1+Q2.

[0100] In a possible implementation, when the refrigerator is in the first operating state, that is, stable operation, the heat flow QS=Q2, Q1=0.

[0101] In this implementation, corresponding parameters are used to calculate the cooling capacity according to different temperature control logics, thereby improving the accuracy of temperature control.

[0108] The first ventilation cooling capacity and the second ventilation cooling capacity are accumulated to obtain the ventilation cooling analysis result.

[0109] In a possible implementation, the preset enthalpy value set is as follows: Figure 3 and Figure 4 As shown, multiple objects include air and common foods, and the corresponding enthalpy value of the object can be queried according to the temperature. In a possible implementation, the weight comparison of the historical weight detection data and the current weight detection data is performed to obtain a weight comparison result, including:

[0110] In the case where the current weight detection data is greater than the historical weight detection data, determining that the weight comparison result is that a new object exists;

[0111] In a case where the current weight detection data is less than or equal to the historical weight detection data, it is determined that the weight comparison result is that there is no newly added object.

[0112] In a possible implementation, the calculating the second ventilation cooling capacity based on the weight comparison result to obtain the second ventilation cooling capacity includes:

[0113] When the weight comparison result is that there is no newly added object, a preset respiratory heat flow set is obtained; the preset respiratory heat flow set includes multiple objects, the temperature and respiratory heat flow of each object in the preset respiratory heat flow set are in one-to-one correspondence, and the objects of the preset respiratory heat flow set include the newly added object;

[0122] In a possible implementation, the preset respiratory heat flow set is as follows: Figure 5 As shown, the objects include fruits and vegetables. The corresponding respiratory heat flow can be queried for the objects according to the temperature.

[0123] In a possible implementation, the operation ventilation heat Q1 is calculated as follows:

[0124] Q1=△To*A*(h1-h2)

[0125] in,

[0126] h1 first enthalpy value: enthalpy value of air at ambient temperature,

[0127] h2 second enthalpy value: the enthalpy value of air at the preset temperature threshold,

[0128] △To: Refrigerator door opening time,

[0129] A: The preset ventilation heat coefficient is summarized by the laboratory.

[0130] In one possible implementation, enthalpy is an important state parameter in thermodynamics that characterizes the energy of a material system. The enthalpy value in air refers to the total heat contained in the air; the enthalpy difference is the difference in heat of an object at two different temperatures. The enthalpy value of an object can be obtained by looking up a preset enthalpy value set, such as Figure 3 shown.

[0131] In a possible implementation, the calculation formula of Q2 is as follows: Q2 = Φ2a + Φ2c + Φ2d

[0132] In one possible implementation, the calculation formula of Q2 is as follows:

[0133] Q2=Φ2a+Φ2c+Φ2d

[0134] in:

[0135] Φ2a: Fruit and vegetable heat flow (W) = m*(H1-H2) / (3.6*t), H1 is the enthalpy value of the initial temperature (i.e., ambient temperature) of the newly added fruits and vegetables (i.e., the newly added objects) before being placed in the refrigerator, H2 is the enthalpy value of the newly added fruits and vegetables after being cooled to the target temperature (i.e., the preset temperature threshold), m is the difference between the current weight detection data and the historical weight detection data, and t is the length of time the refrigerator door is opened;

[0136] Φ2c: Respiratory heat flow rate when goods are cooled (W) = m*(q1+q2) / 2; q1, q2 are the respiratory heat flow rate per unit mass of the initial temperature / target temperature of the newly added fruits and vegetables, and m is the difference between the current weight detection data and the historical weight detection data;

[0137] Φ2d: Respiration heat flow rate of goods during refrigeration (W) = (Mz-m)*q2; Mz is the total weight of fruits and vegetables, that is, the current weight detection data, and m is the difference between the current weight detection data and the historical weight detection data.

[0138] In a possible implementation, when the refrigerator is in the second operating state, that is, when the refrigerator door is opened and fresh fruits and vegetables are put in, the heat flow QS=Q1+Q2.

[0139] In a possible implementation, the respiratory heat flow of the fruits and vegetables is obtained by querying the preset respiratory heat flow set, and the preset respiratory heat flow set is as follows: Figure 4 shown.

[0140] In this implementation, based on the information on the refrigerator storage status collected by the temperature detection device, the weight detection device and the door status detection device, the required refrigeration capacity under different operating conditions is calculated, which improves the accuracy of determining the refrigeration capacity and thereby improves the accuracy of calculating the refrigeration control data.

[0141] In step S105, refrigeration control analysis is performed based on the current refrigeration capacity analysis result to obtain current refrigeration control data.

[0142] In a possible implementation, performing refrigeration control analysis based on the current refrigeration capacity analysis result to obtain current refrigeration control data includes:

[0143] Based on the relationship between the current refrigeration capacity analysis result and the refrigeration system, the air volume of the refrigeration system is calculated, and the air volume of the refrigeration system is determined as the current refrigeration control data.

[0144] In a possible implementation, when the temperature detected by the infrared sensor is greater than or equal to Tb+0.5℃, the compressor is turned on, and the air volume V of the fan can be obtained according to the required cooling capacity, which is the heat flow QS of the fruit and vegetable compartment plus the heat flow △Q required to reduce the temperature of fruits and vegetables by 1℃. QT=QS+△Q; the fan operates according to the calculated air volume parameter V, and stops cooling when the temperature detected by the infrared temperature sensor is less than or equal to Tb-0.5℃.

[0145] In a possible implementation, the heat flow QS of the fruit and vegetable storage compartment is only the respiratory heat flow of the fruit and vegetable, that is, Qs (steady) = Q1 + Q2 = 0 + Mz * q2; Mz is the weight of the fruit and vegetable, and q2 is the respiratory heat flow per unit mass at temperature Tb. Specifically, △Q = Mz * (H1-H2) / (3.6 * t), t is the estimated cooling time, which is generally taken as 0.5 hours.

[0146] In a possible implementation, relevant temperature and weight data are recorded before opening and after closing the door, and refrigeration is turned on 1 minute after closing the door. The recorded time of opening the refrigerator door is △To and the ambient temperature outside the refrigerator is Ta. The weight of the newly added fruits and vegetables reported by the weight sensor is m, and the total weight is Mz. From this, the required cooling capacity can be calculated as QT=QS=Q1+Q2.

[0147] In a possible implementation, the refrigeration system of the refrigerator is composed of a compressor, an evaporator, a fan, and a damper. The relationship between the current refrigeration capacity analysis result and the refrigeration system is:

[0148] Cooling capacity QT (W) = ρ (air density) * V (air volume) * (h1 evaporator inlet air enthalpy value - h2 evaporator outlet air enthalpy value)

[0149] in:

[0150] ρ(air density):1.2(kg / m3);

[0151] h1 is the enthalpy of the air entering the evaporator, which is the enthalpy of the air at the ambient temperature and can be obtained by looking up the table;

[0152] h2 is the enthalpy value of the air outflow from the evaporator, that is, the enthalpy value of the air at the preset temperature threshold.

[0153] In a possible implementation, based on the relationship between the current refrigeration capacity analysis result and the refrigeration system, air volume control data V for the fan may be calculated and obtained as the current refrigeration control data.

[0154] In this implementation, based on the relationship between the current cooling capacity analysis result and the refrigeration system, the air volume of the refrigeration system is calculated, and the fan of the fruit and vegetable storage compartment is controlled based on the air volume to achieve the purpose of precise temperature control.

[0155] In step S107, the refrigeration system of the refrigerator is controlled according to the current refrigeration control data so that the environment inside the refrigerator meets the preset target conditions.

[0156] In a possible implementation, the fan is controlled according to the calculated air volume control data V.

[0157] In an exemplary embodiment, Figure 5 A method for controlling a refrigerator is shown, comprising steps S201 to S2011.

[0158] S201, detecting that the refrigerator door is open, recording the door opening time, ambient temperature and current weight detection data of the fruit and vegetable storage compartment.

[0159] S203, after the refrigerator door is closed, determine whether there are new fruits and vegetables in the fruit and vegetable storage compartment.

[0160] S205: Determine a temperature control strategy according to the judgment result.

[0161] In a possible implementation, when there are newly added fruits and vegetables, temperature control strategy 1 is executed. Specifically, temperature control strategy 1 is to calculate the required cooling capacity QT according to the newly added fruit and vegetable mass m, the refrigerator door opening time △To, and the ambient temperature Ta when the temperature detection device detects that the current temperature detection data is greater than or equal to Tb+0.5.

[0162] In a possible implementation, when there are no newly added fruits and vegetables, temperature control strategy 2 is executed. Specifically, temperature control strategy 2 is to estimate the cooling capacity QT required to cool the fruit and vegetable compartment to Tb-0.5.

[0163] S207: Determine the required cooling capacity according to the temperature control strategy.

[0164] S209, determining the size of the fan air volume based on the cooling capacity, and starting the cooling.

[0165] S2011, when the temperature detection device detects that the current temperature detection data is <= Tb-0.5, stop cooling.
