The refrigerator has a compressor, an ice maker, a cabinet or box for ice making, and a storage box with a refrigeration device. As an indispensable household appliance in daily life, the precise control of the internal temperature of the refrigerator is crucial for the preservation and storage of food.

[0003] Traditional refrigerator temperature control systems mostly use simple mechanical thermostats or ordinary thermistor sensors. Mechanical thermostats have low accuracy, and the general temperature control error is ±2°C or even larger, which cannot meet the preservation needs of foods such as fresh meat, seafood, breast milk, etc. that require high storage temperatures. Although ordinary thermistor sensors have improved accuracy compared to mechanical thermostats, they still have the problem of slow response speed. When the refrigerator door is opened to take out items, the temperature inside the box will rise rapidly. Ordinary thermistor sensors cannot sense temperature changes in time and feed back to the refrigeration system, resulting in refrigeration delays, causing large temperature fluctuations in the box, affecting the preservation effect of food.

[0036] like Figure 7 , Fig.10As shown, an electronic device includes a temperature sensing structure 1, an embedded mainboard 2, a signal processing module 3, a wireless communication module 4 and a power module 5. The signal processing module 3, the wireless communication module 4 and the power module 5 are all arranged on the embedded mainboard 2. The temperature sensing structure 1, the embedded mainboard 2, the signal processing module 3, the wireless communication module 4 and the power module 5 constitute an intelligent temperature control sensor; specifically, the temperature sensing structure 1 uses photolithography technology to make a nanocomposite thermistor on a ceramic substrate to ensure that it is accurately electrically connected with the microprocessor in the signal processing module 3, the Bluetooth chip of the wireless communication module 4 and the lithium battery of the power module 5. The manufactured sensor is strictly temperature calibrated and performance tested to ensure that its temperature measurement accuracy and stability meet the design requirements. The temperature sensing structure 1 is distributed inside the structure, and there are three temperature sensing structures 1. The temperature sensing structure 1 can directly sense the air temperature in the box. This intelligent temperature control sensor includes a temperature sensing structure 1, a signal processing module 3, a wireless communication module 4 and a power module 5. The temperature sensing structure 1 uses a new type of nanocomposite thermistor, which has extremely high temperature sensitivity and can sense a small temperature change of 0.1°C. The signal processing module 3 includes a high-performance microprocessor, which processes the electrical signal transmitted from the temperature sensing structure 1 quickly and accurately and converts it into a digital temperature signal. The wireless communication module 4 uses Bluetooth 5.0 technology and can be connected to the user's mobile phone APP to achieve remote monitoring and settings. The power module 5 uses a rechargeable micro lithium battery, which is charged through wireless charging technology to ensure that the sensor can continue to work stably.

[0037] Working principle: When the temperature sensing structure 1 senses the temperature change in the refrigerator, its resistance value changes accordingly, thereby generating a corresponding electrical signal. The electrical signal is transmitted to the signal processing module 3, and the microprocessor amplifies, filters, and performs analog-to-digital conversion on the electrical signal to obtain an accurate digital temperature signal. The signal processing module 3 sends the digital temperature signal to the refrigerator control system through the wireless communication module 4. At the same time, if the user connects to the sensor through a mobile phone APP, the temperature information in the refrigerator can also be obtained in real time.

[0038] like Figure 1-11As shown, an electronic device includes a refrigerator body 6 and an intelligent control system. The intelligent control system includes a control mainboard 7, a main control board 8, a refrigeration adjustment module 9, a display module 10 and a storage module 11. The control mainboard 7 is hingedly arranged on the surface of the refrigerator body 6. The inner wall of the refrigerator body 6 is provided with a blocking component 12 for protecting the temperature sensing structure 1. The surface of the refrigerator body 6 is provided with a baffle 13. The interior of the temperature sensing structure 1 is provided with a cold air circulation component 14 for uniform circulation of cold air inside the temperature sensing structure 1. The surface of the control mainboard 7 is provided with a protection component 17. Specifically, the present invention adds an intelligent temperature control sensor and an intelligent control system on the basis of the traditional structure. The intelligent control system includes a main control board 8, a refrigeration adjustment module 9, a display module 10 and a storage module 11. The main control board 8 receives the temperature signal from the intelligent temperature control sensor and issues instructions to the refrigeration adjustment module 9 according to the preset temperature range and algorithm. The refrigeration adjustment module 9 can accurately control the speed and refrigeration capacity of the compressor to achieve accurate adjustment of the temperature in the refrigerator. The display module 10 is used to display information such as the real-time temperature, set temperature and working status in the refrigerator. The storage module 11 stores information such as the optimal preservation temperature range of different foods and historical temperature data.

[0039] like Figure 5 , Figure 6 As shown, the blocking component 12 includes a fixed block 1201, the inner wall of the refrigerator body 6 is fixedly connected with the fixed block 1201, the surface of the fixed block 1201 is fixedly connected with a plug rail 1202, and the inner wall of the plug rail 1202 is movably plugged with a block 1203; specifically, the setting of the blocking component 12 is used to protect and block the surface of the temperature sensing structure 1 so that the temperature sensing structure 1 will not be collided or blocked by stored items, the fixed block 1201 is fixedly installed inside the refrigerator body 6, the block 1203 is plugged into the plug rail 1202, and the block 1203 blocks the temperature sensing structure 1 so that the items will not collide or block the temperature sensing structure 1, thereby not affecting the normal use of the temperature sensing structure 1.

[0040] like Figure 3 , Figure 4As shown, the cold air circulation component 14 includes a sleeve 1401, the sleeve 1401 is arranged inside the refrigerator body 6, the inner wall of the sleeve 1401 is fixedly connected with a connecting frame 1402, the inner wall of the connecting frame 1402 is fixedly connected with an inclined block 1403, and the inner wall of the sleeve 1401 is provided with a fan structure 1404; specifically, the setting of the cold air circulation component 14, according to the intelligent temperature control sensor and the intelligent control system for the intelligent regulation of the internal temperature of the refrigerator body 6, because there may be temperature differences at different positions inside the refrigerator body 6, through the cold air circulation Component 14 can circulate the gas inside the refrigerator body 6 up and down, so that the cold air can flow more evenly in the refrigerator, avoiding the situation where the temperature is too high or too low locally, thereby improving the uniformity of the temperature in the entire refrigerator and better maintaining the freshness and quality of food. When controlling the temperature, two groups of fan structures 1404 are arranged inside the sleeve 1401 up and down. When the fan structure 1404 is running, the top fan structure 1404 draws the air, and the bottom fan structure 1404 sends the gas out, so that the gas inside the refrigerator body 6 can circulate up and down.

[0041] like Figure 3 , Figure 5 As shown, the inner wall of the refrigerator body 6 is provided with a storage plate 15, and the surface of the storage plate 15 is penetrated with an opening 16; specifically, the storage plate 15 is used to place items, and the opening 16 is provided so that when the air is circulated up and down through the cold air circulation component 14, the opening 16 allows the gas to effectively pass through the storage plate 15.

[0042] like Figure 8 , Fig. 9 As shown, the protection component 17 includes a back plate 1701, the protection component 17 includes the back plate 1701, the surface of the control main board 7 is fixedly connected with the back plate 1701, the surface of the back plate 1701 is provided with ventilation holes 1702, and the inner wall of the back plate 1701 is fixedly connected with a fan structure 2 1703; specifically, the setting of the protection component 17 is used to perform protective heat dissipation treatment on the intelligent control system, the protection component 17 is installed on the surface of the intelligent control system, the fan structure 2 1703 is running, and the circulation of air inside the back plate 1701 is accelerated, and the heat is dissipated outward through the ventilation holes 1702.

[0043] like Figure 3 As shown, a weight sensor is provided on the storage plate 15; specifically, the weight sensor is used to detect the amount of food in the box and transmit the data to the main control board 8 to assist the main control board 8 in performing intelligent refrigeration regulation.

[0044] like Figure 1As shown, the intelligent control system can intelligently adjust the refrigeration capacity according to the type and quantity of food and user habits; specifically, energy-saving adjustment based on food type: the preservation requirements of different types of food vary greatly, and the requirements for refrigeration capacity are also completely different. The intelligent control system manually inputs food type information on the mobile phone APP by the user, or uses the built-in image recognition technology to identify the food in the box. When the system identifies the type of food, the main control board 8 will retrieve data such as the optimal preservation temperature range of the corresponding food from the storage module 11. For fruit and vegetable foods, the system will appropriately reduce the refrigeration power to avoid over-refrigeration; for foods such as meat that need to be stored at low temperatures, the system accurately controls the refrigeration capacity to ensure that the temperature is stable in the appropriate range, which not only meets the preservation requirements but also avoids energy waste. Energy-saving strategy based on the number of foods: The weight sensor installed on each layer of the storage board 15 monitors the weight changes of the food in real time and transmits the data to the main control board 8. The main control board 8 estimates the number of foods in the box based on the preset conversion relationship between the unit weight and the number of foods. When the amount of food increases, it means that the heat load of the refrigerator increases. The system will increase the cooling capacity accordingly, quickly reduce the temperature inside the box, and reduce the energy loss caused by the temperature rise of food. On the contrary, when the amount of food decreases, the heat load decreases, and the system automatically reduces the cooling capacity, reduces the compressor running time and power, and reduces energy consumption. For example, if a user buys a large amount of food at one time and puts it in the refrigerator, the system can quickly sense the weight change, increase the cooling power, and quickly cool down. As the food is gradually consumed, the system can reduce the cooling input in time.

[0045] Working principle: Users can set the temperature of different areas such as the refrigerator, freezer, and temperature-changing room through the operation panel on the surface of the refrigerator body 6 or the mobile phone APP. The intelligent temperature control sensor monitors the temperature in the refrigerator in real time and transmits the temperature signal to the main control board 8. The main control board 8 compares the current temperature with the preset temperature. If the temperature exceeds the preset range, the main control board 8 obtains the freshness-keeping characteristics of different foods in the storage module 11 and the current number of foods in the box through the weight sensor installed on each layer of the storage board 15, and intelligently adjusts the compressor speed and cooling capacity through the refrigeration adjustment module 9. At the same time, the display module 10 updates the temperature and working status information in real time, and the storage module 11 records the temperature data, so that users can view the historical temperature curve and understand the operation of the refrigerator.
