Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator system shunt control method, system and intelligent terminal. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and is a type of household appliance.

[0003] Refrigerators mainly use the physical state changes of refrigerants to absorb and release heat to achieve the purpose of cooling. When different parts of the refrigerator require different temperatures, a fixed amount of refrigerant is controlled by branching pipes inside the refrigerator and distributed to different evaporators or refrigeration areas according to a certain path and proportion, so that the refrigerator can achieve the corresponding temperature of each part.

[0004] When the refrigerator door is not closed tightly, the temperature of the refrigerator rises over a period of time, and more refrigerant is needed to operate, resulting in uneven distribution of refrigerant. Summary of the Invention

[0005] In order to reduce the uneven distribution of refrigerant in a refrigerator, the present invention provides a refrigerator system diversion control method, system and intelligent terminal.

[0006] In a first aspect, the present invention provides a refrigerator system flow diversion control method, which adopts the following technical solution:

[0012] Determine the cooling replenishment amount according to the temperature deviation value, control a preset storage device to replenish the cooling replenishment amount and output a preset prompt message;

[0013] When the temperature change value exceeds a preset reference change value, the preset opening and closing device is controlled to close the refrigerator door.

[0014] By adopting the above technical solution, when the detected temperature value exceeds the reference temperature value, the detected temperature value is analyzed to obtain a temperature change value, and based on the comparison between the temperature change value and the reference change value, the storage device is controlled to replenish with a refrigeration replenishment amount, or the opening and closing device is controlled to close the refrigerator door, thereby reducing the probability of uneven refrigerant distribution when the refrigerator door is not closed tightly or the refrigerator door leaks.

[0015] Optionally, the method for controlling the preset opening and closing device to close the refrigerator door further includes:

[0016] Get the item placement model in the refrigerator;

[0017] Place the model based on the object to determine the object shape;

[0018] Determine the blocking volume based on the shape of the item and the pre-set air circulation path;

[0019] Determine the placement of the marker based on the blocking volume, object shape, and pre-set air circulation path;

[0020] When the blocking volume exceeds the preset reference blocking volume, the placement position is determined according to the marked placement posture and the preset air output position, and the placement device preset in the refrigerator is controlled to move and place according to the placement position and the marked placement posture.

[0021] By adopting the above technical solution, the items and the air circulation in the refrigerator are analyzed through the item placement model to obtain the marked placement posture and placement position, and the placement device is controlled to move and place the items according to the placement position and the marked placement posture, so that the posture of the items in the refrigerator can be adjusted to minimize the obstruction of the air in the refrigerator, thereby increasing the speed of temperature distribution in the refrigerator when multiple items are placed in the refrigerator.

[0022] Optionally, a method for determining the marker placement posture includes:

[0025] Determine the target detection posture based on the object shape and air circulation path;

[0026] Determine the detection air volume based on the target object posture, the target detection posture and the preset reference circulating wind speed;

[0027] According to the detected air volume, the posture corresponding to the detected air volume with the largest value is selected as the marker placement posture.

[0028] By adopting the above technical solution, the target object posture, target detection posture and reference circulation wind speed are analyzed to obtain the marked placement posture, so that the posture of the items in the refrigerator can be adjusted to maximize the air volume passing through the refrigerator.

[0029] Optionally, methods for determining placement include:

[0036] Determine a reference placement position according to the mark placement position and the preset air output position, and define the interval center axis of the reference placement position as the reference center axis;

[0037] Determine the axis offset based on the reference center axis and other interval center axes;

[0038] The detection tolerance is determined according to the axis offset, and the mark placement position with the smallest detection tolerance is selected as the placement position.

[0039] By adopting the above technical solution, the target placement position is obtained by analyzing the placement posture of the mark, and the blocking area, spacing distance and detection tolerance are analyzed to obtain the placement position, so that the air in the refrigerator can circulate with minimal obstruction.

[0045] The blowing device preset in the refrigerator is controlled to blow air at the blowing position with a blowing power, and the placing device is controlled to place the items with the updated marked placing posture.

[0046] By adopting the above technical solution, by adjusting the power of the blowing device and blowing towards the blowing position, and adjusting the marking placement posture of the items, the air volume in the refrigerator that circulates through the items can be increased without adjusting the position of the items.

[0047] Optionally, also include:

[0048] When the blocking volume does not exceed the preset reference blocking volume, the minimum cooling capacity of each area is determined according to the item placement model;

[0049] An area in the refrigerator where the detected temperature value exceeds a preset reference temperature value is defined as a detection area;

[0051] Determine other cooling capacity based on other cooling capacity and the preset benchmark cooling capacity of the corresponding area;

[0052] Determine the minimum freezing time of the refrigerator detection area based on the marked refrigeration capacity and other call-out quantities;

[0053] The refrigerator is controlled to be accessed according to other access quantities, and preset alarm information is output.

[0054] By adopting the above technical solution, the minimum refrigeration capacity is analyzed to obtain other call-out amounts, and the refrigerator is controlled to call out, so that refrigerant from other areas can be called out to extend the thawing time of items in the detection area.

[0060] The defrost time is updated according to the marked cooling capacity, other call-out amounts and contact wind speed, and the defrost time with the smallest value is selected from the updated defrost times as the minimized defrost time.

[0061] By adopting the above technical solution, the marked refrigeration capacity, other call-out quantities, item type and item volume are analyzed to obtain the thawing time, and the thawing time with the smallest value is used as the minimized freezing time, thereby improving the accuracy of the minimized freezing time.

[0062] Optionally, the method for determining the minimum freezing time further includes:

[0063] When the object placement model includes preset package features, the package location and package range are determined based on the object placement model and the detection area;

[0064] When the package position coincides with the placement position, obtaining package image information of the package position that coincides with the placement position;

[0077] In summary, this application includes at least one of the following beneficial technical effects:

[0078] 1. When the detected temperature exceeds the reference temperature, the system analyzes the detected temperature to determine a temperature change. Based on the comparison between the temperature change and the reference change, the system controls the storage device to replenish the refrigerant, or controls the opening and closing device to close the refrigerator door.

[0089] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0090] A refrigerator system diversion control method analyzes the temperature inside the refrigerator to control a storage device to retrieve refrigerant, or controls an opening and closing device to close the refrigerator door. Further analysis is performed based on the posture and location of items placed inside the refrigerator and the retrieval of refrigerant from other areas, thereby reducing uneven refrigerant distribution in the refrigerator.

[0091] Reference Figure 1 , the embodiment of the present application discloses a refrigerator system diversion control method, comprising the following steps:

[0092] Step S100: Acquire the detected temperature value in the refrigerator.

[0093] In this embodiment, the refrigerator is configured with different temperature values to form different zones, including a refrigerated zone, a frozen zone, and a fresh-keeping zone. The detected temperature values refer to the temperature values of each zone of the refrigerator, and are determined by parameters detected by temperature sensors preset in each zone of the refrigerator.

[0094] Step S101 : When the detected temperature value exceeds a preset reference temperature value, the detected temperature value is updated according to a preset unit time.

[0095] The baseline temperature is the temperature set by the technician for each refrigerator zone during normal operation. The unit time is the length of time set by the technician to monitor temperature changes. If the measured temperature exceeds the baseline, it indicates that the refrigerator door is not closed tightly or there is a leak. Therefore, the measured temperature is re-obtained after the unit time to determine the refrigerator temperature change.

[0096] Step S102: determining a temperature change value according to the detected temperature values before and after the update.

[0097] The temperature change value refers to the temperature value that the detected temperature value in the refrigerator changes per unit time. The temperature change value is obtained by calculating the difference between the detected temperature values before and after the update.

[0098] Step S103: When the temperature change value does not exceed a preset reference change value, a difference between the detected temperature value and the reference temperature value is calculated as a temperature deviation value.

[0099] The baseline change value is the minimum change in refrigerator temperature set by technicians to indicate a door is not securely closed. The temperature deviation value is the difference between the measured temperature and the baseline temperature. If the temperature change does not exceed the baseline change value, it indicates a door leak. The temperature deviation value is calculated as the difference between the measured temperature and the baseline temperature.

[0100] Step S104: determining a cooling replenishment amount according to the temperature deviation value, controlling a preset storage device to replenish the cooling replenishment amount and outputting a preset prompt message.

[0101] The storage device stores refrigerant and is used in emergencies if the refrigerator door is not securely closed or leaks occur. The refrigerant replenishment quantity is the amount of refrigerant the storage device needs to replenish the refrigerator. The refrigerant replenishment quantity is matched against a pre-set refrigeration database using the temperature deviation value. The refrigeration database contains the correspondence between temperature deviation values and refrigerant replenishment quantities. The refrigeration database is manually configured and is not detailed here.

[0102] Step S105: When the temperature change value exceeds a preset reference change value, the preset opening and closing device is controlled to close the refrigerator door.

[0103] The opening and closing device is a device used to connect to the refrigerator door to assist in closing the refrigerator door. The opening and closing device can use a motor to drive the gear to drive the refrigerator to rotate. When the temperature change value exceeds the reference change value, it means that the refrigerator door is not closed tightly, so the opening and closing device is controlled to close the refrigerator door.

[0104] Reference Figure 2 After controlling the preset opening and closing device to close the refrigerator door, the method further includes:

[0105] Step S200: Obtain an item placement model in the refrigerator.

[0106] The item placement model refers to the three-dimensional data of the items placed in the refrigerator. The image of the items in the refrigerator is captured by a camera, and the infrared sensor scans the parameters of the items in the refrigerator. The item placement model is formed by combining the image and the parameters. The method of forming the item placement model is common knowledge among technicians in this field and will not be elaborated here.

[0107] Step S201: determining the object shape according to the object placement model.

[0108] The object shape refers to the outer contour of the object placed in the refrigerator, and the shape of each object is retrieved from the object placement model as the object shape.

[0109] Step S202: Determine a blocking volume based on the shape of the object and a preset air circulation path.

[0110] The air circulation path is the path for air circulation within the refrigerator, as determined by technicians. Different refrigerators may have different air circulation paths. The blocking volume refers to the volume of the object within the air circulation path. This is determined by calculating the air distribution range from the air circulation path and then extracting the volume within the distribution range from the object's shape as the blocking volume. In this embodiment, the distribution range covers the refrigerator's platform for placing items.

[0111] Step S203: Determine the placement posture of the marker according to the blocking volume, the shape of the object, and the preset air circulation path.

[0112] The marked placement posture refers to the posture of an item placed in the refrigerator, and is obtained by analyzing the blocking volume, the shape of the item, and the preset air circulation path.

[0113] Step S204: When the blocking volume exceeds the preset reference blocking volume, the placement position is determined according to the marked placement posture and the preset air output position, and the placement device preset in the refrigerator is controlled to move and place according to the placement position and the marked placement posture.

[0114] The placing device refers to a device used to place items in the refrigerator. The placing device includes a turntable arranged on a placing platform inside the refrigerator and a pushing device arranged on each inner wall of the refrigerator. The pushing device is provided with a clamping claw for clamping items, and each inner wall of the refrigerator is provided with a guide rail for the pushing device to slide up and down.

[0115] The baseline obstruction volume is the maximum volume of air circulation defined by the technician, without obstruction from items. The air blower is a motor-driven fan mounted on the inner wall of the refrigerator. The air outlet position is the location in the refrigerator designated by the technician for the air blower.

[0116] The placement position refers to the location where items in the refrigerator are placed. When the blocking volume exceeds the reference blocking volume, it means that the items in the refrigerator block the air flow in the refrigerator. The marked placement posture and the air output position are analyzed to obtain the placement position, and the placement device in the refrigerator is controlled to move and place the items in the refrigerator according to the placement position.

[0117] Reference Figure 3 , the method for determining the marker placement posture includes:

[0118] Step S300: Determine the detection edge according to the shape of the object and the air circulation path.

[0119] The detection edge refers to the edge of the object's shape. In this embodiment, if the object in the air circulation path is cylindrical, the detection edge is a straight line on the cylinder. If the object in the air circulation path is spherical or hemispherical, the object has no detection edge.

[0120] Step S301: determining a detection angle based on the detected edges, and taking the shape of the detection edge with the minimum angle facing the air circulation path as the target object posture.

[0121] The detection angle is the angle between the two sides of the detection edge. The detection edge is used to retrieve the planes on both sides of the detection edge from the object shape, and the angle between these planes is used as the detection angle. The target object posture refers to the posture of the object when the detection edge with the smallest angle is facing the air circulation path. The posture corresponding to the detection edge with the smallest angle is retrieved from the object shape and facing the air circulation path is used as the target object posture.

[0122] Step S302: Determine the target detection posture according to the object shape and the air circulation path.

[0123] The target detection posture refers to the posture of an object when it is placed perpendicular to the plane of the placement platform and facing the air circulation path. This is done by extracting the plane perpendicular to the air circulation path from the object's shape and using the posture corresponding to this plane facing the air circulation path as the target detection posture.

[0124] Step S303: determining the detection air volume according to the target object posture, the target detection posture and a preset reference circulating wind speed.

[0125] The baseline circulating wind speed is the wind speed set by technicians when the blower is in operation. The detection air volume refers to the volume of air passing through when an object is placed in the target object posture or the target detection posture. The simulation system inputs the target object posture, the target detection posture, and the baseline circulating wind speed into the simulation. The air volume is measured when the air reaches the target object posture or the target detection posture, and this air volume is used as the detection air volume.

[0126] Step S304: selecting the posture corresponding to the maximum detected air volume according to the detected air volume as the marker placement posture.

[0127] The marker placement posture refers to the target object posture or target detection posture corresponding to the maximum detection air volume.

[0128] Reference Figure 4 , methods for determining placement include:

[0129] Step S400: Determine the maximum blocking distance according to the marker placement posture and the air circulation path.

[0130] The maximum blocking distance refers to the maximum distance that the object with the marked placement posture blocks the air. The maximum width perpendicular to the air circulation path and within the distribution range is retrieved from the shape of the object with the marked placement posture as the maximum blocking distance.

[0131] Step S401: Determine different target placement positions according to the maximum blocking distance, the preset placement distance, and the preset reference spacing distance.

[0132] The placement distance is the maximum distance between the items and the air output position set by the technician. The reference spacing distance refers to the minimum distance between each item parallel to the air circulation path.

[0133] The target placement position refers to the center position of an item when placed using the reference spacing distance, placement distance, and maximum obstruction distance. Items marked with placement positions are placed using the reference spacing distance, placement distance, and maximum obstruction distance. There are different placement methods for items, and the center position of the item in each placement method is used as the target placement position.

[0134] Step S402: Determine the spacing distance according to the target placement position.

[0135] The spacing distance refers to the distance between each item parallel to the air circulation path, and the spacing distance is greater than or equal to the reference spacing distance.

[0136] Step S403: Determine the blocking area according to the maximum blocking distance and the marker placement posture.

[0137] The blocking area refers to the maximum area of air blocked by an object when it is placed in the marked placement posture. The blocking area is calculated by retrieving the size parameters within the distribution range of the object shape in the marked placement posture and combining them with the maximum blocking distance.

[0138] Step S404: determining a blocking coefficient according to the blocking area and the spacing distance, and selecting a marker placement position from the target placement positions according to the blocking coefficient.

[0139] The obstruction coefficient is the amount of air obstruction created by an object. The obstruction coefficient is determined by entering the obstruction area and distance into a pre-set obstruction database. The smaller the obstruction coefficient, the greater the airflow through the object. The obstruction database contains the correspondence between obstruction area, distance, and obstruction coefficient. This database is manually configured and will not be detailed here.

[0140] The mark placement position refers to the target placement position with the smallest blocking coefficient, and the target placement position with the smallest blocking coefficient is selected from the target placement positions as the mark placement position.

[0141] Step S405: Determine the interval center axis according to the interval distance of the mark placement positions.

[0142] The interval center axis refers to the center axis of the interval distance between the marker placement positions, and the corresponding center line is obtained from the interval distance between the marker placement positions as the interval center axis.

[0143] Step S406: Determine a reference placement position according to the marked placement position and the preset air output position, and define the interval center axis of the reference placement position as the reference center axis.

[0144] The reference placement position refers to the position of the mark placement position close to the air output position. By connecting the air output position and the mark placement position, the mark placement position corresponding to the straight line where no other mark placement positions appear is used as the reference placement position.

[0145] Step S407: Determine the axis offset based on the reference center axis and other interval center axes.

[0146] The axis offset is the horizontal distance between the reference axis and the other interval axis. The axis offset is calculated by calculating the horizontal distance between the reference axis and the other interval axis. The line corresponding to the axis offset is perpendicular to the air circulation path.

[0147] Step S408: Determine the detection tolerance according to the axis offset, and select the mark placement position with the smallest detection tolerance as the placement position.

[0148] The inspection tolerance refers to the difference between the center axis of the other intervals and the reference center axis. The inspection tolerance is calculated by dividing the axis offset by 0. The method for calculating the inspection tolerance is common knowledge among those skilled in the art and will not be detailed here. The smaller the inspection tolerance, the smaller the distance between the front and rear marker placements, thus increasing the air volume. The placement position refers to the marker placement position that minimizes the inspection tolerance.

[0149] Reference Figure 5 , after determining the blocking volume, the method further comprises:

[0150] Step S500: When the blocking volume does not exceed a preset reference blocking volume, the marker placement position is determined according to the marker placement posture and the object placement model.

[0151] When the blocking volume does not exceed the reference blocking volume, it indicates that there is an object close to the air output position to block the air circulation, and the position of the object with the marked placement posture is retrieved from the object placement model as the marked placement position.

[0152] Step S501: Determine the spacing position and spacing distance according to the placement position of the markers.

[0153] The interval position refers to the center position of the interval distance between the placement positions of each mark. The straight-line distance between each position point on the center axis of the interval distance and the air output position is calculated, and the position point with the smallest straight-line distance is taken as the interval position.

[0154] Step S502: Select the interval position with the largest value from the interval distances and located within the air circulation path as the blowing position.

[0155] The blowing position refers to the position where the blowing device blows air, and the interval position with the largest value is selected from the interval distances and is within the air circulation path as the blowing position.

[0156] Step S503: determining the blowing power according to the blowing position and the preset air output position and updating the mark placement posture.

[0157] The baseline power is the power set by the technician for normal operation of the blower. The blower power refers to the position at which the blower blows air. The blower power is matched by calculating the blowing distance between the blowing position and the air output position, inputting the blowing distance and the baseline power into a pre-set blower database. The blower database contains the correspondence between blowing distance, baseline power, and blower power. The blower database is manually set and will not be detailed here.

[0158] The offset angle is obtained by analyzing the straight line corresponding to the blowing distance and the straight line of the air circulation path, and the marker placement posture is rotated by the offset angle to obtain a new marker placement posture.

[0159] Step S504: controlling the blowing device preset in the refrigerator to blow air at the blowing position with the blowing power, and controlling the placing device to place the items in the updated marked placement posture.

[0160] The blowing device is controlled to blow air at the blowing position with a blowing power, and the placing device is controlled to place the items in the updated marked placement posture.

[0161] Reference Figure 6 , after determining the blocking volume, the method further comprises:

[0162] Step S600: When the blocking volume does not exceed a preset reference blocking volume, the minimum cooling capacity of each area is determined according to the object placement model.

[0163] The minimum cooling capacity refers to the minimum amount of refrigerant required for items in each area of the refrigerator. The item placement model is used to identify the item type and item volume, and the item type and item volume are input into the preset refrigeration database to match the amount of refrigerant. The maximum amount of refrigerant is used as the minimum cooling capacity.

[0164] Step S601: defining an area in the refrigerator where the detected temperature value exceeds a preset reference temperature value as a detection area.

[0165] The detection area refers to the area where refrigerant from other areas needs to be transferred. The detection area is defined by the area where the detected temperature value in the refrigerator exceeds the reference temperature value.

[0166] Step S602: The minimum cooling capacity is retrieved according to the detection area as the marked cooling capacity, and the minimum cooling capacity of other areas is retrieved as the other cooling capacity.

[0167] The marked cooling capacity refers to the minimum cooling capacity of the detection area, and the other cooling capacity refers to the minimum cooling capacity of other areas of the refrigerator. The minimum cooling capacity of the detection area is selected from the minimum cooling capacity as the marked cooling capacity, and the minimum cooling capacity of other areas is used as the other cooling capacity.

[0168] Step S603: Determine other cooling capacities based on other cooling capacities and a preset benchmark cooling capacity for the corresponding area.

[0169] The baseline cooling capacity is the amount of refrigerant required for other areas, as determined by technicians. The other transfer capacity is the maximum amount of refrigerant that can be transferred from other areas. The difference between the other cooling capacity and the baseline cooling capacity for the corresponding area is used as the other transfer capacity.

[0170] Step S604: Determine the minimum freezing time of the refrigerator detection area according to the marked refrigeration capacity and other retrieved capacities.

[0171] Minimum freezing time is the minimum time it takes for items in a detection zone to thaw when refrigerant is transferred from other zones. This is determined by analyzing the marked refrigeration capacity and other transferred capacities.

[0172] Step S605: Control the refrigerator to access according to other access quantities, and output a preset alarm message.

[0173] The warning message is set by the technician to alert the operator to a refrigerator door leak. The diversion system refers to the system used to distribute refrigerant within the refrigerator. This system controls the refrigerator to draw refrigerant at a different volume and outputs a warning message to the operator's terminal. When the time it takes to draw refrigerant reaches the minimum freezing time, the process jumps to step S101.

[0174] Reference Figure 7, methods for determining the minimum freezing time include:

[0175] Step S700: Determine the object type and object volume according to the object placement model and the detection area.

[0176] The item type refers to the type of item placed in the detection area, and the item volume refers to the volume of the item placed in the detection area. The type of item in the detection area is identified by the item placement model as the item type, and the volume of the item corresponding to the item type is retrieved from the item placement model as the item volume.

[0177] Step S701: Determine the thawing time according to the item type, item volume and detected temperature value.

[0178] The defrost time is the time it takes for an item to thaw at the detected temperature. This time is determined by entering the item type, volume, and detected temperature into a pre-set defrost database. This database contains the correspondence between item type, volume, and detected temperature. The defrost database is manually configured and will not be detailed here.

[0179] Step S702: Determine a placement location based on the item type and the item placement model.

[0180] The placement position refers to the position where the object is placed in the detection area, and the position of the object type is retrieved from the object placement model as the placement position.

[0181] Step S703: Obtain contact wind speed according to the placement position.

[0182] The contact wind speed refers to the wind speed to which the object is subjected at the placement location. The wind speed at the placement location is detected by a preset ultrasonic sensor as the contact wind speed.

[0183] Step S704: updating the defrost time according to the marked cooling capacity, other called-up quantities and the contact wind speed, and selecting the defrost time with the smallest value from the updated defrost time as the minimized defrost time.

[0184] The total demanded amount is calculated by adding the marked cooling capacity and other demanded amounts. The contact air velocity and total demanded amount are then input into a pre-set defrost database to match different defrost times. The minimum defrost time is then selected as the minimum defrost time. The defrost database also contains the corresponding relationships between the total amount of ice maker, contact air velocity, and defrost time, which will not be detailed here.

[0185] Reference Figure 8 , the method for determining the minimum freezing time also includes:

[0186] Step S800: When the object placement model includes preset package features, the package location and package range are determined according to the object placement model and the detection area.

[0187] The "wrapping characteristics" are the characteristics of the items wrapped in the refrigerator, as set by the technician. The "wrapping location" refers to the location of the wrapped item in the detection area, and the "wrapping range" refers to the range of the wrapped item in the detection area.

[0188] When the item placement model includes a wrapping feature, it indicates that an item is wrapped and placed in the detection area of the refrigerator. Therefore, the position of the wrapping feature in the detection area is retrieved from the item placement model as the wrapping position, and the range of the wrapping feature in the detection area is retrieved from the item placement model as the wrapping range.

[0189] Step S801: when the package position coincides with the placement position, obtain package image information of the package position that coincides with the placement position.

[0190] Package image information refers to an image of the package that can identify the type of item. When the package location coincides with the placement location, it indicates that the type of item can be identified through the packaging. The camera then captures an image of the package location that coincides with the placement location as the package image information.

[0191] Step S802: Determine the wrapping material and the laminating range according to the wrapping image information.

[0192] The parcel material refers to the material of the parcel that can identify the item type. The parcel material is determined by identifying the material corresponding to the parcel's features from the parcel image information. The fitting range refers to the range within which the parcel fits the item. The fitting range is determined by identifying the color of the parcel when not attached to the item from the parcel image information and comparing the colors within the parcel range. The range with a higher color density than the color density when the parcel and item are not attached is considered the fitting range.

[0193] Step S803: When the lamination range exceeds a preset reference lamination range, the thermal conductivity coefficient is determined according to the wrapping material.

[0194] The baseline fit range is the minimum heat absorption range for an item, as determined by technicians. If the fit range exceeds this preset baseline fit range, indicating that the item is absorbing heat through the wrapping, the wrapping material is entered into a pre-set wrapping database to determine the thermal conductivity. The wrapping database contains the correspondence between wrapping materials, test temperatures, and thermal conductivity. This database is manually configured and will not be discussed further here.

[0195] Step S804: When the lamination range does not exceed the preset reference lamination range, the thermal conductivity coefficient is determined according to the wrapping material and the detected temperature value.

[0196] When the fitting range exceeds the preset reference fitting range, it means that the heat absorbed by the item needs to be wrapped, and the wrapping material and the detected temperature value are input into the preset wrapping database to match the thermal conductivity coefficient.

[0197] Step S805: determining a target thawing time according to the thermal conductivity and the detected temperature value, and taking the minimum target thawing time as the minimized freezing time.

[0198] The target thawing time is the minimum time required for a packaged item to thaw. The target thawing time is matched by inputting the thermal conductivity coefficient and the detected temperature value into the thawing database, and the minimum target thawing time is used as the minimum freezing time. The thawing database also contains the corresponding relationship between the thermal conductivity coefficient, the detected temperature value, and the target thawing time, which will not be detailed here.
