Technical Field

[0001] This application relates to the field of refrigerator control technology, and in particular to a refrigerator control method and control device. Background Technology

[0002] Refrigerators are a crucial means of preserving food. Fruits and vegetables are beloved in our daily diets, but varying temperatures and temperature fluctuations can significantly impact their quality. Improper storage temperatures can cause a rapid decline in the quality of fruits and vegetables, such as nutrient loss or moisture evaporation. More seriously, they may become infected by microorganisms like mold and bacteria, leading to spoilage. Studies show that most fruits and vegetables achieve good preservation when stored at 2–4 degrees Celsius with temperature fluctuations within ±1 degree Celsius. Therefore, addressing the long-term preservation of fruits and vegetables requires strict temperature control in the storage area of ​​the refrigerator.

[0003] In existing technologies, the thermostat settings need to be adjusted by the user constantly as the seasons change and the ambient temperature fluctuates. Furthermore, the temperature control logic in existing technologies is the same throughout the entire refrigeration and preservation area, failing to precisely control the temperature range of the fruit and vegetable compartment. Therefore, there is an urgent need for a refrigerator control method that can precisely control the temperature. Summary of the Invention

Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] In the home, the refrigerator is one of the most important means of preserving food. Fruits and vegetables are highly seasonal and geographically limited, and are usually stored in the refrigerator's crisper compartment. However, different temperatures and temperature fluctuations can have a significant impact on their quality. Improper storage temperatures can cause a rapid decline in the quality of fruits and vegetables, such as nutrient loss or moisture evaporation. More seriously, they may be infected by microorganisms such as mold and bacteria, leading to spoilage. Studies have shown that for most fruits and vegetables, a storage temperature of 2–4 degrees Celsius with temperature fluctuations of less than ±1°C provides good preservation. Therefore, solving the problem of long-term preservation of fruits and vegetables requires strict temperature control in the refrigerator's fruit and vegetable storage area.

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

[0063] This application provides a refrigerator control method, wherein the refrigerator includes a temperature measuring device and a weight detection device. The temperature measuring device is located at a preset temperature measuring position inside the refrigerator, and the weight detection device is located at a preset weight measuring position inside the refrigerator. (See attached document.) Figure 1 The refrigerator control method includes steps S101 to S107.

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

[0065] In one possible implementation, such as Figure 2 As shown, the refrigerator is equipped with a fruit and vegetable preservation compartment for storing and preserving fresh fruits and vegetables.

[0066] In one possible implementation, such as Figure 2 As shown, the fruit and vegetable preservation room is equipped with fruit and vegetable drawers, which are used to store fruits, vegetables and other food ingredients.

[0067] In one possible implementation, the fruit and vegetable drawer includes a light source and a spectral sensor. The spectral sensor is used to identify the food stored in the fruit and vegetable drawer, facilitating subsequent parameter queries based on the type of food.

[0068] In one possible implementation, such as Figure 2 As shown, the temperature measuring device is located at a preset temperature measuring position inside the refrigerator. The temperature measuring device includes a temperature sensing module and a temperature measuring module. The temperature measuring module is embedded in the preset temperature measuring position of the refrigerator shell near the storage device, and the temperature sensing module is located 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 one 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 with an emissivity of 0.95 is placed at the same horizontal position on the same side of the infrared sensor. The metal temperature sensing plate is installed 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, such as Figure 2 As shown, the weight detection device is located at a preset weight measurement position inside the refrigerator.

[0071] In one possible implementation, such as Figure 2 As shown, the power board of the refrigerator integrates a computing control unit (MCU) and the door status detection. The computing control unit is electrically connected to the door status detection device, the temperature measuring device, the weight detection device, and the refrigeration system.

[0072] In one possible implementation, the refrigerator's refrigeration system includes an inverter compressor, an evaporator, a fan, and an air damper.

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

[0074] In one possible implementation, such as Figure 2 As shown, the refrigerator casing near the fruit and vegetable preservation compartment is equipped with a refrigeration system, which includes an evaporator and a fan. The refrigeration system is used to cool the fruit and vegetable preservation compartment according to the current refrigeration control data.

[0075] In one possible implementation, the refrigeration system for the fruit and vegetable preservation compartment includes a separate evaporator, a fan, and an air vent, which can individually refrigerate the fruit and vegetable preservation compartment in the cold storage area.

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

[0077] In one possible implementation, the current weight detection data is obtained by the weight detection device detecting the weight of the stored objects in the refrigerator at the current time.

[0078] In one possible implementation, the current operating status information represents the open / closed state of the refrigerator door.

[0079] In step S103, based on the current operating status information, the cooling capacity is analyzed using the current temperature detection data and the current weight detection data to obtain the current cooling capacity analysis result.

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

[0081] The step of performing cooling capacity analysis based on the current operating status information, the current temperature detection data, and the current weight detection data to obtain the current cooling capacity analysis result includes:

[0082] When the current operating status information is the first operating status, a stable cooling analysis is performed based on the current temperature detection data, the current weight detection data, and the preset temperature threshold to obtain a stable cooling analysis result, and the stable cooling analysis result is determined as the current cooling analysis result; the preset temperature threshold is a temperature value set based on the preset target conditions.

[0083] When the current operating status information is the second operating status, the door opening time from opening to closing and the ambient temperature around the refrigerator are obtained. Based on the door opening time, the ambient temperature, the current temperature detection data, the current weight detection data and the preset temperature threshold, ventilation and cooling analysis is performed to obtain the ventilation and cooling analysis result, and the ventilation and cooling analysis result is determined as the current cooling analysis result.

[0084] In one 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 can be any value between 2 and 4℃), with a fluctuation range of ±1℃; the cooling temperature control logic of the fruit and vegetable compartment is divided into two control strategies, corresponding to different user refrigerator usage situations.

[0085] In one 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 last opening, the value of n ranges from 4 to 6 (hours).

[0086] In one possible implementation, when the current operating status information is the first operating status, if the temperature detected by the infrared sensor is greater than or equal to Tb + 0.5°C, the required cooling capacity is calculated based on the total weight of the fruits and vegetables and the current temperature inside the fruit and vegetable preservation room. Then, the compressor is activated, and the fan airflow V can be determined based on the required cooling capacity. Specifically, Tb can take any value between 2 and 4°C.

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

[0088] In one possible implementation, the total weight of the current fruits and vegetables is the current weight detection data, and the temperature inside the current fruit and vegetable preservation room is the current temperature detection data.

[0089] In one possible implementation, the second operating state indicates that the door is in an open state, i.e., after the refrigerator door is opened, when the current operating state information is the second operating state.

[0090] In one possible implementation, after the refrigerator door is opened, if new fruits and vegetables are detected to have been placed inside, the required cooling capacity is recalculated based on the weight of the new fruits and vegetables, the door opening time, the ambient temperature, and the current temperature of the fruit and vegetable preservation compartment. Then, the cooling system is activated according to the required cooling capacity.

[0091] In one possible implementation, the weight of the newly added 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 cooling capacity is estimated by combining weight and temperature, which improves the accuracy of refrigerator temperature control.

[0093] In one possible implementation, the step of performing stable cooling analysis based on the current temperature detection data, the current weight detection data, and a preset temperature threshold to obtain stable cooling analysis results includes:

[0094] The current temperature detection data and the preset temperature threshold are compared to obtain a temperature comparison result;

[0095] If 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, the stable cooling analysis result is determined to be that the current environment inside the refrigerator meets the preset target conditions.

[0096] If 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, the stable cooling capacity is calculated based on the current temperature detection data, the current weight detection data and the preset temperature threshold, and the stable cooling capacity is determined as the stable cooling analysis result.

[0097] In one possible implementation, cooling capacity is an abbreviation for the heat flow of the refrigerator's cold compartment. Once the required heat flow in the fruit and vegetable preservation compartment is determined, the cooling capacity required to maintain a specific temperature over a period of time can be determined.

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

[0099] In one possible implementation, the heat flow QS of the fruit and vegetable preservation room consists of two parts: operating ventilation heat Q1 and fruit and vegetable heat Q2, where QS = Q1 + Q2.

[0100] In one possible implementation, when the refrigerator is in the first operating state, i.e., running smoothly, the heat flow is QS = Q2, Q1 = 0.

[0101] In this implementation, the cooling capacity is calculated using corresponding parameters based on different temperature control logics, which improves the accuracy of temperature control.

[0102] In one possible implementation, the step of performing ventilation and cooling analysis 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 the ventilation and cooling analysis results includes:

[0103] Obtain a preset enthalpy value set; the preset enthalpy value set includes multiple objects, and the temperature and enthalpy value of each object in the preset enthalpy value set are in one-to-one correspondence, and the objects in the preset enthalpy value set include air;

[0104] The first enthalpy value is obtained by querying the preset enthalpy value set based on the air and the ambient temperature.

[0105] The second enthalpy value is obtained by querying the preset enthalpy value set based on air and the preset temperature threshold.

[0106] The first ventilation cooling capacity is calculated based on the door opening time, the preset ventilation heat coefficient, the first enthalpy value, and the second enthalpy value; the preset ventilation heat coefficient is set based on experimental data.

[0107] The historical weight detection data and the current weight detection data are compared to obtain a weight comparison result. Based on the weight comparison result, the second ventilation cooling capacity is calculated to obtain the second ventilation cooling capacity. The historical weight detection data is obtained by the weight detection device detecting the weight of objects inside the refrigerator at historical times.

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

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

[0110] If the current weight detection data is greater than the historical weight detection data, the weight comparison result is determined to indicate the presence of a new object.

[0111] If the current weight detection data is less than or equal to the historical weight detection data, the weight comparison result is determined to be that no new object has been added.

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

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

[0114] Based on the newly added object and the preset temperature threshold, the preset respiratory heat flow set is queried to obtain the first respiratory heat flow;

[0115] The second ventilation cooling capacity is calculated based on the current weight detection data and the first respiratory heat flow.

[0116] In one possible implementation, the preset enthalpy value set also includes the newly added object.

[0117] The calculation of the second ventilation cooling capacity based on the weight comparison result, to obtain the second ventilation cooling capacity, includes:

[0118] If the weight comparison result indicates the presence of a new object, a third enthalpy value is obtained by querying the preset enthalpy value set based on the new object and the ambient temperature, and a fourth enthalpy value is obtained by querying the preset enthalpy value set based on the new object and the preset temperature threshold.

[0119] The first heat flow is calculated based on the current weight detection data, the historical weight detection data, the third enthalpy value, and the fourth enthalpy value.

[0120] And a second heat flow is calculated based on the current weight detection data, the historical weight detection data, the first respiratory heat flow, and the second respiratory heat flow; the first respiratory heat flow is obtained by querying the preset respiratory heat flow set based on the stored object and the preset temperature threshold, and the second respiratory heat flow is obtained by querying the preset respiratory heat flow set based on the stored object and the ambient temperature;

[0121] The first heat flow and the second heat flow are summed to obtain the second ventilation cooling capacity.

[0122] In one possible implementation, the preset respiratory heat flow set is as follows: Figure 5 As shown, the objects include fruits and vegetables. The respiratory heat flow can be queried for each object based on temperature.

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

[0124] Q1 = △To * A * (h1 - h2)

[0125] in,

[0126] h1 First enthalpy: The enthalpy 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 exchange coefficient is given by the laboratory.

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

[0131] In one possible implementation, Q2 is calculated as follows: Q2=Φ2a+Φ2c+Φ2d

[0132] In one possible implementation, Q2 is calculated as follows:

[0133] Q2=Φ2a+Φ2c+Φ2d

[0134] in:

[0135] Φ2a: Fruit and vegetable heat flow (W) = m*(H1-H2) / (3.6*t), where H1 is the enthalpy of the initial temperature (i.e., ambient temperature) of the newly added fruit and vegetable (i.e., the newly added object) before it is placed in the refrigerator, H2 is the enthalpy of the newly added fruit and vegetable after it is 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 refrigerator door opening time;

[0136] Φ2c: Breathing heat flow (W) during cargo cooling = m*(q1+q2) / 2; q1 and q2 are the breathing heat flow per unit mass of newly added fruits and vegetables at the initial temperature / target temperature, and m is the difference between the current weight detection data and the historical weight detection data;

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

[0138] In one 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 one possible implementation, the respiration heat flux of the fruits and vegetables is obtained by querying a preset set of respiration heat fluxes, such as... Figure 4 As shown.

[0140] In this implementation, the required cooling capacity under different operating conditions is calculated based on the information of the refrigerator's storage status collected by the temperature detection device, weight detection device, and door status detection device. This improves the accuracy of the cooling capacity determination and, consequently, the accuracy of the cooling control data calculation.

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

[0142] In one possible implementation, the step of performing refrigeration control analysis based on the current refrigeration capacity analysis results to obtain current refrigeration control data includes:

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

[0144] In one possible implementation, when the temperature detected by the infrared sensor is greater than or equal to Tb + 0.5℃, the compressor is activated. The fan's airflow V can be calculated based on the required cooling capacity, which is the heat flow QS in the fruit and vegetable compartment plus the heat flow ΔQ required to lower the temperature of the fruits and vegetables by 1℃. QT = QS + ΔQ. The fan operates according to the calculated airflow parameter V. When the temperature detected by the infrared temperature sensor is less than or equal to Tb - 0.5℃, cooling is stopped.

[0145] In one possible implementation, the heat flow QS in the fruit and vegetable storage compartment consists only of the respiration heat flow of the fruits and vegetables, i.e., Qs(steady) = Q1 + Q2 = 0 + Mz * q2; where Mz is the weight of the fruits and vegetables, and q2 is the respiration heat flow per unit mass at temperature Tb. Specifically, ΔQ = Mz * (H1 - H2) / (3.6 * t), where t is the estimated cooling time, typically taken as 0.5 hours.

[0146] In one possible implementation, relevant temperature and weight data are recorded before the door is opened and after it is closed. Cooling is turned on 1 minute after the door is closed. The recorded time the refrigerator door is opened is ΔTo, 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. Therefore, the required cooling capacity at this time can be calculated as QT = QS = Q1 + Q2.

[0147] In one possible implementation, the refrigerator's refrigeration system consists of a compressor, evaporator, fan, and damper. The relationship between the current cooling capacity analysis result and the refrigeration system is as follows:

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

[0149] in:

[0150] ρ (air density): 1.2 (kg / m3);

[0151] The enthalpy of the air entering the evaporator h1 is the enthalpy of air at ambient temperature, which can be found in a table.

[0152] The enthalpy of the air outlet from the h2 evaporator is the enthalpy of the air at the preset temperature threshold.

[0153] In one possible implementation, based on the relationship between the current cooling capacity analysis results and the cooling system, the airflow control data V for the fan can be calculated and used as the current cooling control data.

[0154] In this implementation, the air volume of the refrigeration system is calculated based on the relationship between the current cooling capacity analysis results and the refrigeration system. The fan in the fruit and vegetable storage room is then controlled based on the air volume to achieve 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 one possible implementation, the fan is controlled based on the calculated air volume control data V.

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

[0158] S201, the refrigerator door is detected to be open, and the opening time, ambient temperature, and current weight detection data of the fruit and vegetable storage compartment are recorded.

[0159] S203 determines whether new fruits and vegetables are added to the fruit and vegetable storage compartment after the refrigerator door is closed.

[0160] S205 determines the temperature control strategy based on the judgment result.

[0161] In one possible implementation, when new fruits and vegetables are added, temperature control strategy one is executed. Specifically, temperature control strategy one involves calculating the required cooling capacity QT based on the mass m of the newly added fruits and vegetables, the refrigerator door opening time ΔTo, and the ambient temperature Ta when the temperature detection device detects that the current temperature data is >= Tb + 0.5.

[0162] In one possible implementation, if no new fruits and vegetables are added, temperature control strategy two is executed. Specifically, temperature control strategy two involves estimating the cooling capacity QT required to lower the temperature of the fruit and vegetable compartment to Tb-0.5.

[0163] S207 determines the required cooling capacity based on the temperature control strategy.

[0164] S209 determines the fan airflow based on the cooling capacity and starts the cooling process.

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