Description

Technical Field

[0001] This application relates to the technical field of smart appliances, and more particularly to a cooling method, apparatus, device, and smart appliance for a smart appliance. Background Technology

[0002] As people's living standards improve and technologies such as the internet, big data, artificial intelligence, and voice interaction become more widespread, traditional lifestyles are gradually changing, and the use of home appliances is increasingly moving towards intelligentization. While bringing more convenience to users, the functions of various home appliances are also becoming more diversified.

[0003] Existing smart refrigerators typically use a fixed air outlet layout. Cold air is generated by the evaporator and then evenly distributed to all areas inside the refrigerator through fixed air ducts and outlets. When users put fresh food into the refrigerator, it takes a long time for the food to reach the ideal preservation temperature because the cold air is dispersed throughout the refrigerator space rather than being concentrated on cooling the newly placed food. Summary of the Invention

[0004] This application provides a cooling method, apparatus, device, and smart appliance for intelligent electrical appliances, which can quickly identify and rapidly cool newly added ingredients.

[0005] On one hand, this application provides a cooling method for a smart appliance, the method comprising: The smart appliance includes multiple shelves, with a pressure sensor installed under each shelf. An infrared sensor array is installed inside the smart appliance. The method includes: The pressure sensor was used to detect the weight change of each shelf before and after the smart appliance door was closed; Based on the weight change results of each shelf, the target area where the newly added ingredients are located in the smart appliance is determined; The initial temperature of the newly added food ingredient in the target area is detected based on the infrared sensor array. If the initial temperature is greater than the refrigeration temperature threshold of the smart appliance, the cooling parameters of the air outlet of the smart appliance are adjusted based on the target area where the newly added food is located.

[0006] In one exemplary embodiment, the step of detecting the weight change of each shelf before and after the smart appliance door is closed based on the pressure sensor includes: Upon detecting that the smart appliance door is open, the first weight of each shelf is detected based on the pressure sensor. When the smart appliance door is detected to be closed, a second weight of each shelf is detected based on the pressure sensor; Based on the difference between the second weight and the first weight corresponding to each shelf, the weight change of each shelf before and after the smart appliance door is closed is determined.

[0007] In one exemplary embodiment, each shelf corresponds to multiple pressure sensors, and the multiple pressure sensors on each shelf divide each shelf into multiple detection areas. Determining the target area where newly added food is located in the smart appliance based on the weight change results of each shelf includes: Obtain the weight change results for each detection area in each shelf layer; The detection area representing the weight increase based on the weight change results is identified as the target area where the newly added ingredients are located in the smart appliance.

[0008] In one exemplary embodiment, the air outlet of the smart appliance is provided with an air outlet parameter adjustment component, which includes an air outlet angle adjustment mechanism and an air volume adjustment valve. Adjusting the cooling parameters of the smart appliance's air outlet based on the target area where the newly added food is located includes: Based on the target area corresponding to the newly added ingredients, the target direction of the air outlet is determined; Based on the initial temperature corresponding to the newly added ingredients, the target air volume of the air outlet is determined; The air outlet angle adjustment mechanism is controlled to adjust the orientation of the air outlet to the target direction; The airflow regulating valve is controlled to adjust the airflow at the air outlet to the target airflow.

[0009] In one exemplary embodiment, the air vent angle adjustment mechanism includes a horizontal rotation mechanism, a vertical adjustment mechanism, a first motor, and a second motor. The horizontal rotation mechanism is electrically connected to the first motor, and the vertical adjustment mechanism is electrically connected to the second motor. Determining the target direction of the air vent based on the target area corresponding to the newly added food ingredient includes: Based on the target area corresponding to the newly added ingredients, determine the first angle of the air outlet in the horizontal direction and the second angle in the vertical direction; The control mechanism for adjusting the air outlet angle to the target direction includes: The first operating parameters of the first motor are determined based on the first angle, and the second operating parameters of the second motor are determined based on the second angle. The first motor is controlled to operate according to the first operating parameters to drive the horizontal rotation mechanism to adjust the angle of the air outlet in the horizontal direction to the first angle; The second motor is controlled to operate according to the second operating parameters to drive the vertical adjustment mechanism to adjust the angle of the air outlet in the vertical direction to the second angle.

[0010] In one exemplary embodiment, adjusting the cooling parameters of the smart appliance's air outlet based on the target area where the newly added ingredient is located includes: The cooling phase of the smart appliance is divided into a rapid cooling phase, a balanced cooling phase, and a normal cooling phase; the rapid cooling phase corresponds to a first duration, and the balanced cooling phase corresponds to a second duration. The first airflow of the rapid cooling stage is obtained by adding a preset ratio to the preset airflow at the air outlet. During the rapid cooling phase, the air outlet is controlled to blow air along the target direction according to the first air volume, and the power of the compressor in the smart appliance is increased. If the cumulative air outlet duration is detected to have reached the first duration, the smart appliance is controlled to enter the balanced cooling stage. When the cumulative duration of the smart appliance operating according to the working parameters of the balanced cooling stage reaches the second duration, the smart appliance is controlled to enter the normal cooling stage.

[0011] In one exemplary embodiment, controlling the smart appliance to enter the balanced cooling stage includes: During the balanced cooling stage, the real-time temperature of the newly added ingredients is obtained at preset time intervals. Based on the real-time detected temperature corresponding to different preset time periods, the first air volume of the air outlet is gradually reduced to obtain the second air volume corresponding to each preset time period. The air outlet is controlled to sequentially discharge air according to the second air volume of each preset time period, and the power of the compressor is gradually reduced.

[0012] On the other hand, a cooling device for a smart appliance is provided. The smart appliance includes multiple shelves, with a pressure sensor disposed below each shelf. An infrared sensor array is disposed inside the smart appliance. The device includes: The weight change determination module is used to detect the weight change of each shelf before and after the smart appliance door is closed, based on the pressure sensor. The target area determination module is used to determine the target area where the newly added food ingredients are located in the smart appliance based on the weight change results of each shelf. An initial temperature detection module is used to detect the initial temperature of the newly added food ingredient in the target area based on the infrared sensor array; The cooling parameter adjustment module is used to adjust the cooling parameters of the air outlet of the smart appliance based on the target area where the newly added food is located if the initial temperature is greater than the refrigeration temperature threshold of the smart appliance.

[0013] On the other hand, a smart appliance is provided, which uses the above-mentioned refrigeration method, and the smart appliance is one of a refrigerator or a freezer.

[0014] On the other hand, an electronic device is provided, the device including a processor and a memory, the memory storing at least one instruction or at least one program, the at least one instruction or the at least one program being loaded and executed by the processor to implement the cooling method of the smart appliance as described above.

[0015] On the other hand, a computer storage medium is provided that stores at least one instruction or at least one program, which is loaded and executed by a processor to implement the cooling method of the intelligent appliance as described above.

[0016] On the other hand, a computer program product is provided, which includes computer instructions for performing the cooling method of the intelligent appliance as described above.

[0017] The cooling method, apparatus, equipment, and smart appliance provided in this application have the following technical advantages: The smart appliance of this application includes multi-layer shelves, with a pressure sensor installed under each shelf. An infrared sensor array is installed inside the smart appliance. The pressure sensors detect the weight change of each shelf before and after the appliance door is closed. Based on the weight change of each shelf, the target area where newly added food is located in the smart appliance is determined. Thus, the pressure sensors can quickly and accurately identify newly added food in the smart appliance. Then, the infrared sensor array detects the initial temperature of the newly added food in the target area. If the initial temperature is higher than the refrigeration temperature threshold of the smart appliance, the cooling parameters of the smart appliance's air outlet are adjusted based on the target area where the newly added food is located. After identifying the newly added food, the initial temperature of the target area where the newly added food is located can be further detected by the infrared sensors to obtain the temperature of the newly added food. If the initial temperature is detected to be higher than the refrigeration temperature threshold of the smart appliance, it is determined that the temperature of the newly added food is too high and requires cooling. Therefore, based on the location of the target area, the cooling parameters of the smart appliance's air outlet are adjusted so that the air outlet faces the target area, achieving rapid cooling of the newly added food.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the embodiments of this application, the terms "module" or "unit" refer to a computer program or part of a computer program that has a predetermined function and works with other related parts to achieve a predetermined goal, and can be implemented wholly or partially using software, hardware (such as processing circuitry or memory), or a combination thereof.

Furthermore, each module or unit can be part of an overall module or unit that includes the functionality of that module or unit.

[0023] The following describes a cooling method for a smart appliance according to this application. Figure 1 This is a flowchart illustrating a cooling method for a smart appliance provided in an embodiment of this specification. This specification provides the operational steps of the method described in the embodiment or flowchart, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiment is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server products, the method can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment) as shown in the embodiment or drawings. The smart appliance includes multiple shelves, with a pressure sensor disposed below each shelf. An infrared sensor array is disposed on the inner side of the smart appliance, specifically as follows... Figure 1 As shown, the method may include: S101: Based on the pressure sensor, detect the weight change of each shelf before and after the smart appliance door is closed. In the embodiments described in this specification, the smart appliance also includes a control module, through which the method of this embodiment is executed. The smart appliance can be a refrigerator, freezer, or other appliance with refrigeration function. The smart appliance may have multiple shelves, with a pressure sensor installed under each shelf. The pressure sensor converts mechanical deformation (applied pressure / gravity) into changes in resistance / voltage. Multiple pressure sensors can be installed under each shelf, dividing each shelf into multiple detection areas (such as a 3×3 grid layout). Each pressure sensor corresponds to one detection area, facilitating the detection of pressure changes in different areas of each shelf before and after the smart appliance is closed, thereby further determining the weight changes in different areas of each shelf. An infrared sensor array can be installed on the inner top of the smart appliance, covering the entire area inside the refrigerator to detect the temperature in different areas. The number of sensors in the infrared sensor array can be set according to actual conditions.

[0024] S103: Based on the weight change results of each shelf, determine the target area where the newly added ingredients are located in the smart appliance.

[0025] In the embodiments of this specification, the area where the weight increased after the smart appliance was closed can be determined based on the weight change results of different detection areas in each shelf, and this area can be identified as the target area where the newly added food is located. For example, to improve detection accuracy and reduce errors, a weight increment threshold can be set, and the detection area where the weight change result indicates a weight increment greater than the weight increment threshold can be identified as the target area.

[0026] S105: Detect the initial temperature of the newly added food ingredient in the target area based on the infrared sensor array.

[0027] In the embodiments of this specification, the infrared sensor array may include multiple infrared sensors. When the smart appliance door is opened and then closed, after determining the target area, the initial temperature of the newly added food in the target area can be detected by the infrared sensor array. Specifically, the target sensor corresponding to the target area can be selected from the infrared sensor array, and then the initial temperature of the target area can be collected by the target sensor. If there are multiple target sensors, the collected temperature of each target sensor can be obtained, and the average value of the collected temperatures of multiple target sensors can be calculated as the initial temperature of the newly added food.

[0028] S107: If the initial temperature is greater than the refrigeration temperature threshold of the smart appliance, adjust the cooling parameters of the air outlet of the smart appliance based on the target area where the newly added food is located.

[0029] In the embodiments of this specification, the refrigeration temperature threshold of the smart appliance can be obtained, that is, the temperature of the food stored in the smart appliance under the refrigeration effect; by comparing the initial temperature with the refrigeration temperature threshold of the smart appliance, it is determined whether the newly added food needs to be refrigerated; if the initial temperature is less than or equal to the refrigeration temperature threshold of the smart appliance, then refrigeration is not required; for example, if the food has just been taken out and immediately put in, or if the temperature of the food put in is already very low, then refrigeration is not required.

[0030] If the initial temperature is higher than the refrigeration temperature threshold of the smart appliance, it indicates that the added food is above the refrigeration temperature of the smart appliance. In this case, cooling treatment is required for the added food. The cooling parameters of the smart appliance's air outlet can be adjusted according to the target area where the added food is located. For example, the cooling parameters of the air outlet may include, but are not limited to, air volume, air direction, air temperature, and pressure.

[0031] When it is detected that multiple new foods have been added after the refrigerator door was opened once, the new foods can be divided into room temperature foods and cooled foods based on the initial temperature of each new food; then the room temperature new foods are identified as target foods and cooled down.

[0032] For example, a smart appliance could be a refrigerator, such as... Figure 2 As shown, Figure 2 This is a schematic diagram of a refrigerator refrigeration system, including an external sensor array 01, shelves 02, pressure sensors 03, and a control module 04. Multiple small pressure sensors 03 are installed below each shelf 02, dividing the shelf 02 into several detection areas (such as a 3×3 grid layout). Simultaneously, an infrared sensor array 01 is installed on the top inside the refrigerator to detect the thermal radiation characteristics of food, thereby determining the initial temperature of newly added food. Based on the detection results from the pressure sensors 03 and the external sensor array 01, the control module 04 quickly identifies newly added food and can distinguish between room-temperature food and already cooled food, thus determining which room-temperature food requires refrigeration and enabling targeted refrigeration.

[0033] In some embodiments, the step of detecting the weight change of each shelf before and after the smart appliance door is closed based on the pressure sensor includes: Upon detecting that the smart appliance door is open, the first weight of each shelf is detected based on the pressure sensor. When the smart appliance door is detected to be closed, a second weight of each shelf is detected based on the pressure sensor; Based on the difference between the second weight and the first weight corresponding to each shelf, the weight change of each shelf before and after the smart appliance door is closed is determined.

[0034] In the embodiments described in this specification, when the user opens the refrigerator door, the system automatically activates the detection mode; after the door closes, the pressure sensor detects the weight changes in each area, and the infrared sensor detects the temperature distribution. Specifically, when the smart appliance door is detected to be open, the system detects the first weight of each detection area on each shelf based on the pressure sensor; when the smart appliance door is detected to be closed, the system detects the second weight of each detection area on each shelf based on the pressure sensor; then, the difference between the second weight and the first weight corresponding to each detection area is calculated to obtain the weight change result of each detection area on each shelf; thus accurately identifying the weight change results of each detection area before and after the smart appliance door is closed.

[0035] In some embodiments, each shelf corresponds to multiple pressure sensors, and the multiple pressure sensors on each shelf divide each shelf into multiple detection areas. Determining the target area where newly added food is located in the smart appliance based on the weight change results of each shelf includes: Obtain the weight change results for each detection area in each shelf layer; The detection area representing the weight increase based on the weight change results is identified as the target area where the newly added ingredients are located in the smart appliance.

[0036] In the embodiments of this specification, the weight change result may include a weight increase result, a weight decrease result, and a weight unchanged result. For example, in order to improve the detection accuracy and reduce errors, a weight increment threshold can be set. When the weight change result is a weight increase result, the detection area where the weight increment is greater than the weight increment threshold is determined as the target area. This allows for accurate identification of the target area corresponding to the newly added ingredients.

[0037] For example, if the weight change result is a weight reduction, the airflow of the air outlet or other cooling parameters can be reduced based on the total weight of the food currently stored in the smart appliance, in order to minimize the energy consumption of the smart appliance.

[0038] In some embodiments, the air outlet of the smart appliance is provided with an air outlet parameter adjustment component, which includes an air outlet angle adjustment mechanism and an air volume adjustment valve. Adjusting the cooling parameters of the air outlet of the smart appliance based on the target area where the newly added food is located includes: Based on the target area corresponding to the newly added ingredients, the target direction of the air outlet is determined; Based on the initial temperature corresponding to the newly added ingredients, the target air volume of the air outlet is determined; The air outlet angle adjustment mechanism is controlled to adjust the orientation of the air outlet to the target direction; The airflow regulating valve is controlled to adjust the airflow at the air outlet to the target airflow.

[0039] In the embodiments of this specification, for newly added food with an initial temperature higher than the refrigeration temperature threshold of the smart appliance, the target direction of the air outlet can be determined by the target area where the food is located; and the target airflow of the air outlet can be determined based on the initial temperature of the newly added food. For example, if the initial temperature is low, a smaller target airflow can be set; if the initial temperature is high, a larger target airflow can be set. Then, the orientation of the air outlet can be adjusted to the target direction by controlling the air outlet angle adjustment mechanism; and the airflow regulating valve can be controlled to adjust the airflow of the air outlet to the target airflow; thereby enabling the newly added food to cool down quickly and improving the food preservation effect.

[0040] In some embodiments, the air vent angle adjustment mechanism includes a horizontal rotation mechanism, a vertical adjustment mechanism, a first motor, and a second motor. The horizontal rotation mechanism is electrically connected to the first motor, and the vertical adjustment mechanism is electrically connected to the second motor. Determining the target direction of the air vent based on the target area corresponding to the newly added food ingredient includes: Based on the target area corresponding to the newly added ingredients, determine the first angle of the air outlet in the horizontal direction and the second angle in the vertical direction; Accordingly, controlling the air outlet angle adjustment mechanism to adjust the orientation of the air outlet to the target direction includes: The first operating parameters of the first motor are determined based on the first angle, and the second operating parameters of the second motor are determined based on the second angle. The first motor is controlled to operate according to the first operating parameters to drive the horizontal rotation mechanism to adjust the angle of the air outlet in the horizontal direction to the first angle; The second motor is controlled to operate according to the second operating parameters to drive the vertical adjustment mechanism to adjust the angle of the air outlet in the vertical direction to the second angle.

[0041] In this embodiment, the air outlet angle adjustment mechanism includes a horizontal rotation mechanism, a vertical adjustment mechanism, a first motor, and a second motor. The horizontal rotation mechanism is electrically connected to the first motor, and the vertical adjustment mechanism is electrically connected to the second motor. The horizontal rotation mechanism is used to adjust the horizontal air outlet angle, and the vertical adjustment mechanism is used to adjust the vertical air outlet angle. This embodiment can also set the horizontal rotation angle range of the horizontal rotation mechanism and the vertical adjustment angle range of the vertical adjustment mechanism. The horizontal rotation angle range and the vertical adjustment angle range can be the same or different, and can be set according to actual conditions; no specific limitation is made here.

[0042] For example, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of an air outlet cooling parameter adjustment system for a smart appliance. The smart appliance includes a control module and an air outlet cooling parameter adjustment mechanism. The air outlet cooling parameter adjustment mechanism includes an evaporator, a fan, a main air duct, and a smart air outlet connected in sequence. The smart air outlet includes a horizontal rotation mechanism and a vertical adjustment mechanism. For example, the horizontal rotation angle of the horizontal rotation mechanism is in the range of -60° to 60°, and the vertical adjustment angle of the vertical adjustment mechanism is in the range of -30° to 30°. The target direction and target air volume of the air outlet can be determined by the control module. The target direction may include a first angle along the horizontal direction and a second angle along the vertical direction of the air outlet. Then, based on the first angle, a first operating parameter of the first motor is determined, and based on the second angle, a second operating parameter of the second motor is determined. The first motor is controlled to operate according to the first operating parameter to drive the horizontal rotation mechanism to adjust the angle of the air outlet along the horizontal direction to the first angle. The second motor is controlled to operate according to the second operating parameter to drive the vertical adjustment mechanism to adjust the angle of the air outlet along the vertical direction to the second angle. The target power of the fan is determined according to the target air volume, and the fan is controlled to operate according to the target power to ensure that the air volume of the air outlet reaches the target air volume.

[0043] In this embodiment, the specific types of the first motor and the second motor can be selected according to the actual situation; for example, the first motor can be a stepper motor and the second motor can be a servo motor; the stepper motor continuously consumes power (full current excitation) when maintaining the position, while the current of the servo motor can drop to near zero after reaching the target position.

[0044] In some embodiments, such as Figure 4 As shown, Figure 4 This is a flowchart illustrating a method for adjusting the cooling parameters of the air outlet of a smart appliance based on the target area where the newly added ingredient is located. The method includes: S401: The cooling phase of the smart appliance is divided into a rapid cooling phase, a balanced cooling phase, and a normal cooling phase; the rapid cooling phase corresponds to a first duration, and the balanced cooling phase corresponds to a second duration. S403: Increase the preset air volume at the air outlet by a preset ratio to obtain the first air volume of the rapid cooling stage; S405: During the rapid cooling phase, the air outlet is controlled to discharge air along the target direction according to the first air volume, and the power of the compressor in the smart appliance is increased. S407: When the cumulative air outlet duration is detected to have reached the first duration, the smart appliance is controlled to enter the balanced cooling stage; S409: When the cumulative duration of the smart appliance performing operation according to the working parameters of the balanced cooling stage reaches the second duration, control the smart appliance to enter the normal cooling stage.

[0045] In the embodiments of this specification, the cooling stage of the smart appliance is divided into a rapid cooling stage, a balanced cooling stage, and a normal cooling stage; the rapid cooling stage corresponds to a first duration, and the balanced cooling stage corresponds to a second duration; the first duration and the second duration can be the same or different; for example, the first duration and the second duration can both be set to 30 minutes, the rapid cooling stage is 30 minutes after the start of cooling, the balanced cooling stage is from the 30th minute to the 60th minute, and the normal cooling stage is the time after the 60th minute.

[0046] During the rapid cooling phase, the air outlet is controlled to discharge air along the target direction at the first airflow rate, and the power of the compressor in the smart appliance is increased. For example, the preset airflow rate of the smart appliance under normal operating conditions can be obtained first, and then a preset percentage can be added to the preset airflow rate at the air outlet to obtain the first airflow rate for the rapid cooling phase. The preset percentage can be set according to actual conditions, for example, it can be set to 150%, that is, increasing the preset airflow rate by 150% to obtain the first airflow rate. The power of the compressor in the smart appliance can also be increased by a target percentage (e.g., 110%) based on its rated power. When the cumulative airflow duration at the air outlet reaches the first duration, the smart appliance is controlled to enter the balanced cooling phase. When the cumulative duration of the smart appliance operating according to the working parameters of the balanced cooling phase reaches the second duration, the smart appliance is then controlled to enter the normal cooling phase. This time-segmented intelligent cooling strategy ensures the preservation of newly added ingredients while also protecting existing ingredients, and achieves energy-saving operation of the smart appliance.

[0047] In some embodiments, such as Figure 5 As shown, Figure 5 A schematic diagram of a process for controlling the smart appliance to enter the balanced cooling stage, including: S4071: During the balanced cooling stage, the real-time temperature of the newly added food ingredient is obtained at preset time intervals. S4073: Based on the real-time detected temperature corresponding to different preset time periods, gradually reduce the first air volume of the air outlet to obtain the second air volume corresponding to each preset time period; S4075: Control the air outlet to sequentially discharge air according to the second air volume of each preset time period, and gradually reduce the power of the compressor.

[0048] In the embodiments of this specification, during the balanced cooling stage, the directional airflow is gradually reduced based on temperature sensor feedback; the compressor power gradually returns to normal; and the cooling needs of other areas are also addressed. Specifically, the real-time temperature of the newly added food can be obtained at preset time intervals; then, based on the real-time temperature corresponding to different preset time intervals, the first airflow of the air outlet is gradually reduced to obtain the second airflow corresponding to each preset time interval; finally, the air outlet is controlled to sequentially discharge air according to the second airflow of each preset time interval, and the compressor power is gradually reduced; thereby ensuring rapid cooling of the newly added food while also addressing the cooling needs of other existing food in the smart appliance.

[0049] In some embodiments, controlling the smart appliance to enter the normal cooling phase includes: controlling the air outlet to face the initial direction, controlling the air volume of the air outlet to the initial air volume, and controlling the smart appliance to enter an energy-saving operation mode during the normal cooling phase. Specifically, the air outlet can return to its normal position to restore uniform airflow; the system can then return to the energy-saving operation mode.

[0050] This embodiment achieves an optimal balance between cooling efficiency and energy saving by precisely controlling time and adjusting power, ensuring rapid cooling of fresh ingredients while avoiding excessive energy consumption. Compared to traditional cooling methods, the time for fresh ingredients to reach the ideal temperature is reduced by 60%, while overall energy consumption increases by only 15%.

[0051] In one exemplary embodiment, such as Figure 6 As shown, Figure 6 A flowchart illustrating a cooling control strategy for a smart appliance, such as... Figure 6 As shown in Figure a, this refrigeration control method includes a rapid cooling stage, a balanced cooling stage, and a normal cooling stage. In the rapid cooling stage: the air vents are directed towards the new food, and the airflow is increased to 150%; the compressor power is moderately increased (110% of rated power); other areas maintain basic airflow to ensure overall temperature stability. In the balanced cooling stage: based on temperature sensor feedback, the directional airflow is gradually reduced; the compressor power gradually returns to normal; and the system begins to meet the cooling needs of other areas. In the normal cooling stage: the air vents return to their normal positions, restoring uniform airflow; the system returns to energy-saving operation mode. Figure 6 Figure b shows the air volume power change curve, total power consumption change curve, and compressor power change curve for the three working stages. It can be seen that the cooling speed of new food is increased by 60%, shortening the time from 30 minutes to 12 minutes, with an overall energy consumption increase of only 15%, achieving energy saving through intelligent control. It also improves the food preservation effect and reduces the loss of nutrients and deterioration of quality.

[0052] As can be seen from the technical solutions provided in the embodiments of this specification above, the smart appliance in these embodiments includes multiple shelves, with a pressure sensor installed under each shelf. An infrared sensor array is installed inside the smart appliance. Based on the pressure sensors, the weight change of each shelf before and after the smart appliance door is closed is detected. Based on the weight change of each shelf, the target area where the newly added food is located in the smart appliance is determined. Thus, the pressure sensor can quickly and accurately identify the newly added food in the smart appliance. Then, based on the infrared sensor array, the initial temperature of the newly added food in the target area is detected. If the initial temperature is greater than the refrigeration temperature threshold of the smart appliance, the cooling parameters of the air outlet of the smart appliance are adjusted based on the target area where the newly added food is located. After identifying the newly added food, the initial temperature of the target area where the newly added food is located can be further detected by the infrared sensor to obtain the temperature of the newly added food. When the initial temperature is detected to be greater than the refrigeration temperature threshold of the smart appliance, it is determined that the temperature of the newly added food is high and needs to be cooled. Therefore, based on the location of the target area, the cooling parameters of the air outlet of the smart appliance are adjusted so that the air outlet is directed towards the target area, thereby achieving rapid cooling of the newly added food.

[0053] This specification also provides an intelligent appliance that uses the above-described refrigeration method. The intelligent appliance is one of a refrigerator or a freezer.

Based on the weight change of each shelf, the target area where newly added food is located in the smart appliance is determined. Thus, the pressure sensors can quickly and accurately identify newly added food in the smart appliance. Then, the infrared sensor array detects the initial temperature of the newly added food in the target area.

After identifying the new ingredient, the initial temperature of the target area where the new ingredient is located can be detected by an infrared sensor to obtain the temperature of the new ingredient. If the initial temperature is detected to be higher than the refrigeration temperature threshold of the smart appliance, it is determined that the temperature of the new ingredient is too high and needs to be refrigerated. Then, according to the location of the target area, the cooling parameters of the air outlet of the smart appliance are adjusted so that the air outlet is directed towards the target area to achieve rapid cooling of the new ingredient.
