DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] A refrigerator system flow diversion control method analyzes the temperature in the refrigerator to control a storage device to retrieve refrigerant, or controls an opening and closing device to close the refrigerator door, and further analyzes the posture and location of items in the refrigerator and the retrieval of refrigerant in other areas, thereby reducing the uneven distribution of refrigerant in the refrigerator.

[0028] Reference Figure 1 The embodiment of the present application discloses a refrigerator system flow diversion control method, comprising the following steps: Step S100: Acquire the detected temperature value in the refrigerator.

[0029] In this embodiment, the refrigerator has different temperature values ​​to form different areas, including a refrigeration area, a freezing area, and a fresh-keeping area, etc. The detected temperature value refers to the temperature value of each area of ​​the refrigerator, and the parameters detected by the temperature sensors preset in each area of ​​the refrigerator are used as the detected temperature value.

[0030] 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.

[0031] The reference temperature value is the temperature value set by the technician when each area of ​​the refrigerator is operating normally. The unit time is the length of time set by the technician to detect temperature changes. When the detected temperature value exceeds the reference temperature value, it means that the refrigerator door is not closed or there is a leak, so the detected temperature value is obtained again after a unit time to obtain the change value of the refrigerator temperature.

[0032] Step S102: determining a temperature change value according to the detected temperature values ​​before and after the update.

[0033] The temperature change value refers to the temperature value that the detected temperature value in the refrigerator changes per unit time, and the temperature change value is obtained by calculating the difference between the detected temperature values ​​before and after the update.

[0034] 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.

[0035] The reference change value is the minimum change value of the refrigerator temperature when the refrigerator door is not closed tightly, set by the technician. The temperature deviation value refers to the deviation between the detected temperature value and the reference temperature value. When the temperature change value does not exceed the reference change value, it means that the refrigerator door is leaking. Therefore, the difference between the detected temperature value and the reference temperature value is calculated as the temperature deviation value.

[0036] Step S104: determining the refrigeration replenishment amount according to the temperature deviation value, controlling a preset storage device to replenish with the refrigeration replenishment amount and outputting a preset prompt message.

[0037] The storage device refers to a device that stores refrigerant and is used in an emergency when the refrigerator door is not closed or leaks. The refrigeration replenishment amount refers to the amount of refrigerant that the storage device needs to replenish for the refrigerator. The refrigeration replenishment amount is matched from the preset refrigeration database through the temperature deviation value. The refrigeration database contains the corresponding relationship between the temperature deviation value and the refrigeration replenishment amount. The refrigeration database is set manually and will not be described in detail here.

[0038] Step S105: When the temperature change value exceeds a preset reference change value, a preset opening and closing device is controlled to close the refrigerator door.

[0039] The opening and closing device refers to a device used to connect to the refrigerator door to assist the refrigerator door in closing. 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. Reference Figure 2 , the method after controlling the preset opening and closing device to close the refrigerator door also includes: Step S200: Obtain a model of item placement in the refrigerator.

[0040] 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 through the picture 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.

[0041] Step S201: determining the object shape according to the object placement model.

[0042] 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.

[0043] Step S202: determining a blocking volume according to the shape of the object and a preset air circulation path.

[0044] The air circulation path is the path for air circulation in the refrigerator set by the technician. Different refrigerators can have different air circulation paths. The blocking volume refers to the volume of the object shape in the air circulation path. The distribution range of air is obtained from the air circulation path, and the volume within the distribution range is intercepted from the object shape as the blocking volume. In this embodiment, the distribution range can cover the platform on the refrigerator where the objects are placed.

[0045] 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.

[0046] The marked placement posture refers to the posture of an item placed in the refrigerator, and the marked placement posture is obtained by analyzing the blocking volume, the shape of the item, and the preset air circulation path.

[0047] 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.

[0048] 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 in 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.

[0049] The reference blocking volume is the maximum volume set by the technician where the items do not block the air circulation. The blowing device is a fan installed on the inner wall of the refrigerator and driven by a motor. The air output position is the position set by the technician where the refrigerator is installed with the blowing device.

[0050] The placement position refers to the position where the 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.

[0051] Reference Figure 3 , the method for determining the marker placement posture includes: Step S300: determining the detection edge according to the shape of the object and the air circulation path.

[0052] The detection edge refers to the edge in the shape of the object. In this embodiment, if the shape of the object in the air circulation path is a cylinder, the detection edge is a straight line on the cylinder. If the shape of the object in the air circulation path is a sphere or a hemisphere, the object has no detection edge.

[0053] Step S301: determining a detection angle according to the detection edges, and taking the shape of the detection edge with the minimum angle facing the air circulation path as the target object posture.

[0054] The detection angle refers to the angle between the two sides of the detection edge. The planes on both sides of the detection edge are retrieved from the object shape through the detection edge, and the angle between the 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 faces the air circulation path. The detection edge with the smallest angle is retrieved from the object shape, and the posture corresponding to the detection edge facing the air circulation path is used as the target object posture.

[0055] Step S302: Determine the target detection posture according to the shape of the object and the air circulation path.

[0056] The target detection posture refers to the posture of the object when it is placed perpendicular to the plane of the placement platform and facing the air circulation path. The plane perpendicular to the air circulation path is retrieved from the shape of the object, and the posture corresponding to the plane facing the air circulation path is used as the target detection posture.

[0057] Step S303: determining the detection air volume according to the target object posture, the target detection posture and a preset reference circulation wind speed.

[0058] The reference circulation wind speed is the wind speed set by the technician when the blowing device is in operation. The detection wind volume refers to the volume of air passing through when the object is placed in the target object posture or the target detection posture. The target object posture, the target detection posture and the reference circulation wind speed are input into the simulation system for simulation, and the wind volume when the air circulates to the target object posture or the target detection posture is detected, and the wind volume is used as the detection wind volume.

[0059] Step S304: selecting the posture corresponding to the detected wind volume with the largest value as the marking placement posture according to the detected wind volume.

[0060] The marker placement posture refers to the target object posture or target detection posture corresponding to the maximum detection air volume.

[0061] Reference Figure 4 , methods for determining placement include: Step S400: Determine the maximum blocking distance according to the marker placement posture and the air circulation path.

[0062] 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.

[0063] Step S401: Determine different target placement positions according to the maximum blocking distance, the preset placement distance, and the preset reference spacing distance.

[0064] 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 the items parallel to the air circulation path.

[0065] The target placement position refers to the center position of the object when it is placed with the reference spacing distance, placement distance and maximum blocking distance. The objects marked with placement postures are placed with the reference spacing distance, placement distance and maximum blocking distance, and there are different placement methods when placing the objects. The center position of the objects in different placement methods is used as the target placement position.

[0066] Step S402: Determine the spacing distance according to the target placement position.

[0067] The spacing distance refers to the distance between each object parallel to the air circulation path, and the spacing distance is greater than or equal to the reference spacing distance.

[0068] Step S403: Determine the blocking area according to the maximum blocking distance and the marker placement posture.

[0069] The blocking area refers to the maximum area of ​​air blocked when the object is placed in the marked placement posture. The blocking area is calculated by retrieving the size parameters within the distribution range from the shape of the object in the marked placement posture and based on the size parameters and the maximum blocking distance.

[0070] Step S404: determining a blocking coefficient according to the blocking area and the spacing distance, and selecting a marking placement position from the target placement positions according to the blocking coefficient.

[0071] The blocking coefficient refers to the coefficient value of the air blocking caused by the object. The blocking area and the interval distance are input into the preset blocking database to match the blocking coefficient. The smaller the blocking coefficient, the greater the air volume when passing through the object. The blocking database contains the corresponding relationship between the blocking area, the interval distance and the blocking coefficient. The blocking database is set manually and will not be elaborated here.

[0072] 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.

[0073] Step S405: Determine the interval center axis according to the interval distance of the mark placement position.

[0074] The interval center axis refers to the center axis of the interval distance between the mark placement positions, and the corresponding center line is obtained from the interval distance between the mark placement positions as the interval center axis.

[0075] 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.

[0076] The reference placement position refers to the position of the marked placement position close to the air output position. By connecting the air output position and the marked placement position, the marked placement position corresponding to the straight line without other marked placement positions is used as the reference placement position.

[0077] Step S407: Determine the axis offset according to the reference center axis and other interval center axes.

[0078] The axis offset refers to the horizontal distance between the other interval center axis and the reference center axis, and the axis offset is calculated by calculating the horizontal distance between the reference center axis and the other interval center axis. The straight line corresponding to the axis offset is perpendicular to the air circulation path.

[0079] 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.

[0080] The detection tolerance refers to the tolerance between the other interval center axis and the reference center axis. The detection tolerance is calculated by dividing the axis offset by 0. The calculation method of the detection tolerance is common knowledge among technicians in this field and will not be described here. The smaller the detection tolerance, the smaller the distance of the interval deviation between the front and rear mark placement positions, so the greater the air volume passing through. The placement position refers to the mark placement position with the smallest detection tolerance.

[0081] Reference Figure 5, the method after determining the blocking volume further comprises: 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.

[0082] 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.

[0083] Step S501: Determine the spacing position and spacing distance according to the marker placement position.

[0084] The spacing position refers to the center position of the spacing distance between the positions of each mark. The straight-line distance between each position point on the center axis of the spacing distance and the air output position is calculated, and the position point with the smallest straight-line distance is taken as the spacing position.

[0085] Step S502: Select the interval position with the largest value from the interval distances and within the air circulation path as the blowing position.

[0086] 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.

[0087] Step S503: determining the blowing power according to the blowing position and the preset air output position and updating the mark placement posture.

[0088] The reference power is the power of the blowing device when it is in normal operation, which is set by the technician. The blowing power refers to the position where the blowing device blows air to the blowing position. The blowing distance between the blowing position and the air output position is calculated, and the blowing distance and the reference power are input into the preset blowing database to match the blowing power. The blowing database contains the corresponding relationship between the blowing distance, the reference power, and the blowing power. The blowing database is set manually and will not be described in detail here.

[0089] 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.

[0090] Step S504: Control the blowing device preset in the refrigerator to blow air at the blowing position with the blowing power, and control the placing device to place the items with the updated marked placing posture.

[0091] 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 objects in the updated marked placing posture.

[0092] Reference Figure 6 , the method after determining the blocking volume further comprises: 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.

[0093] 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.

[0094] Step S601: defining an area in the refrigerator where the detected temperature value exceeds a preset reference temperature value as a detection area.

[0095] The detection area refers to the area where refrigerant from other areas needs to be transferred. The area where the detected temperature value in the refrigerator exceeds the reference temperature value is defined as the detection area.

[0096] Step S602: according to the detection area, the minimum cooling capacity is retrieved as the marked cooling capacity, and the minimum cooling capacity of other areas is retrieved as other cooling capacity.

[0097] 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.

[0098] Step S603: Determine other cooling capacities according to other cooling capacities and a preset benchmark cooling capacity for the corresponding area.

[0099] The benchmark cooling capacity is the amount of refrigerant required for other areas set by the technicians. The other transfer capacity refers to the maximum amount of refrigerant that can be transferred from other areas. The difference between the other cooling capacity and the benchmark cooling capacity of the corresponding area is calculated as the other transfer capacity.

[0100] Step S604: Determine the minimum freezing time of the refrigerator detection area according to the marked refrigeration capacity and other retrieved quantities.

[0101] Minimum freezing time refers to the minimum time for items in the detection area to thaw when the detection area uses refrigerant from other areas. The minimum freezing time is obtained by analyzing the marked refrigeration capacity and other used capacities.

[0102] Step S605: Control the refrigerator to retrieve according to other retrieved quantities, and output a preset alarm message.

[0103] The alarm information is set by the technician to remind the operator that the refrigerator door has leaked. The diversion system refers to the system used to distribute refrigerant in the refrigerator. By controlling the diversion system preset in the refrigerator to call with other call amounts and outputting the alarm information to the terminal held by the operator, when the time for the refrigerator to call other call amounts reaches the minimum freezing time, jump to step S101.

[0104] Reference Figure 7 , methods for determining the minimum freezing time include: Step S700: Determine the object type and object volume according to the object placement model and the detection area.

[0105] The item type refers to the type of the 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 the item in the detection area is identified through 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.

[0106] Step S701: Determine the thawing time according to the item type, item volume and detected temperature value.

[0107] The thawing time refers to the time it takes for an item to thaw at the detected temperature. The thawing time is matched by inputting the item type, item volume, and detected temperature value into a preset thawing database. The thawing database contains the correspondence between the item type, item volume, and detected temperature value. The thawing database is manually set and will not be described in detail here.

[0108] Step S702: Determine a placement location according to the item type and the item placement model.

[0109] The placement position refers to the position where the object in the detection area is placed, and the position of the object type is retrieved from the object placement model as the placement position.

[0110] Step S703: Obtain contact wind speed according to the placement position.

[0111] The contact wind speed refers to the wind speed to which the object at the placement location is subjected. The wind speed at the placement location is detected by a preset ultrasonic sensor as the contact wind speed.

[0112] Step S704: updating the defrosting time according to the marked cooling capacity, other retrieved capacities and contact wind speed, and selecting the defrosting time with the smallest value from the updated thawing time as the minimized freezing time.

[0113] By calculating the sum of the marked refrigeration capacity and other call-up amounts as the total call-up amount, the contact wind speed and the total call-up amount are input into the preset thawing database to match each thawing time, and the minimum thawing time is selected as the minimized freezing time. The thawing database also contains the correspondence between the total amount of ice-making agent, the contact wind speed and the thawing time, which will not be elaborated here.

[0114] Reference Figure 8 , the method for determining the minimum freezing time also includes: Step S800: When the object placement model includes a preset package feature, the package location and package range are determined according to the object placement model and the detection area.

[0115] The wrapping feature is the feature of the wrapped items in the refrigerator set by the technician. The wrapping position refers to the position of the wrapped items in the detection area, and the wrapping range refers to the range of the wrapped items in the detection area.

[0116] 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.

[0117] 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.

[0118] Package image information refers to an image of a package that can identify the type of item. When the package position coincides with the placement position, it means that the type of item can be identified through the packaging. The camera then captures an image of the package position that coincides with the placement position as the package image information.

[0119] Step S802: Determine the wrapping material and the laminating range according to the wrapping image information.

[0120] The package material refers to the material of the package that can identify the type of the item. The material corresponding to the package feature is identified from the package image information as the package material. The fitting range refers to the range where the package and the item are fitted. The color when the package and the item are not fitted is identified from the package image information, and the colors of the package range are compared. The range of colors with a higher color concentration than the color concentration when the package and the item are not fitted is taken as the fitting range.

[0121] Step S803: When the bonding range exceeds a preset reference bonding range, the thermal conductivity coefficient is determined according to the wrapping material.

[0122] The reference fitting range is the minimum range of heat absorption of the item set by the technician. When the fitting range exceeds the preset reference fitting range, it means that the item absorbs heat through the wrapping, and the wrapping material is input into the preset wrapping database to match the thermal conductivity coefficient. The wrapping database contains the corresponding relationship between the wrapping material, the detection temperature value and the thermal conductivity coefficient. The wrapping database is a manually set database and will not be described here.

[0123] Step S804: When the lamination range does not exceed the preset reference lamination range, the thermal conductivity coefficient is determined according to the package material and the detected temperature value.

[0124] When the fitting range exceeds the preset reference fitting range, it means that the heat absorbed by the article 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.

[0125] 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.

[0126] The target thawing time refers to the minimum time required for the packaged items to be thawed. 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 minimized 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 elaborated here.
