Description

Technical Field

[0001] This invention relates to the field of rapid cooling equipment technology, and more particularly to a rapid cooling device, a cold storage chamber, and a control method. Background Technology

[0002] With the improvement of people's living standards, low-temperature fermented milk products have become an indispensable part of people's daily lives, and with the increase in social demand, production is also increasing year by year. In the production process of low-temperature fermented milk products, after filling, they need to be quickly sent to a low-temperature cold storage (1-6℃) for rapid cooling to ensure product quality.

[0003] In practical applications, cryogenic products are typically packaged in cardboard or plastic boxes, stacked on pallets, and then placed on large shelves in cold storage for unified cooling. However, due to the limitations of the packaging and the stacking on pallets, the cryogenic products inside the boxes cannot be effectively and quickly cooled. Existing technology simply places the airflow unit behind the shelf, which accelerates airflow, but the gap between the product and the airflow unit is large, allowing a large amount of air to enter the airflow unit through the gap, while the airflow within the product does not change significantly, resulting in low cooling efficiency. Secondly, existing technology has poor adaptability, making it difficult to adjust the space according to specific products, thus failing to improve cooling efficiency and wasting a large amount of energy from the airflow unit and cold storage resources. Thirdly, air pumps typically operate in a unidirectional manner, meaning that inflation and deflation can only occur at one time. This setup requires two air pumps to work together to expand and contract the airbag, increasing control difficulties and reducing operational reliability. Finally, existing technology has a low degree of automation, making it difficult to flexibly and automatically operate according to the arrival of goods, requiring manual intervention in the cooling process and consuming a large amount of manpower and resources.

[0004] Therefore, embodiments of the present invention are proposed. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a rapid cooling device to address the shortcomings of existing technologies, such as poor adaptability to rapid cooling of products, difficulty in adjusting space according to specific products, resulting in difficulty in improving cooling efficiency, waste of large amounts of energy from the refrigerant flow unit, and waste of large amounts of cold storage resources. The device achieves efficient rapid cooling by adjusting the size of the refrigerant flow space according to the product size, ensuring close arrangement of products.

[0006] This invention also proposes a cold storage facility to address the shortcomings of existing cold storage technologies, where uniform cooling on large cold storage shelves makes it difficult to effectively and quickly cool low-temperature products. This facility enables the establishment of a comprehensive rapid cooling solution based on product type and space dimensions, achieving efficient and safe rapid cooling operations.

[0007] This invention also proposes a control method for a rapid cooling device to address the shortcomings of existing technologies, such as low automation in rapid cooling of products and the inability to formulate specific rapid cooling schemes based on products. This method enables the establishment of a complete rapid cooling scheme based on product type and space dimensions, achieving efficient and safe rapid cooling operations.

[0008] According to a first aspect of the present invention, a rapid cooling device includes: a top airbag, a side airbag, a tray, a drainage unit, and an air pump assembly;

[0009] The top airbag is positioned above the tray;

[0010] The two side airbags are respectively disposed on a pair of opposite sides of the tray;

[0011] The drainage unit is located on one side of another pair of opposite sides of the tray;

[0012] The air pump assembly is connected to the top airbag and the two side airbags respectively;

[0013] The top airbag facing the tray, the two side airbags facing each other, and the top side of the tray surround and form a receiving chamber.

[0014] The diversion unit is used to introduce refrigerant into the containment chamber;

[0015] The air pump assembly is used to adjust the gas content inside the top airbag and the side airbags.

[0016] According to one embodiment of the present invention, the air pump assembly includes an air pump, a main pipeline, a branch pipeline, a valve body, and a flow sensor;

[0017] The air pump is connected to the main pipeline;

[0018] The main pipeline is connected to multiple branch pipelines;

[0019] The branch pipes are respectively connected to the top airbag and the side airbags;

[0020] Each of the valve bodies is provided in a one-to-one correspondence with one of the branch pipes;

[0021] Each of the flow sensors is configured in a one-to-one correspondence with one of the branch pipes.

[0022] Specifically, this embodiment proposes an air pump assembly configuration scheme. By configuring an air pump, a main pipeline, and branch pipelines, it is possible to deliver gas from the air pump into the interior of the top airbag and the side airbag, or to extract gas from the interior of the top airbag and the side airbag. Alternatively, the air pump itself can have both of the above functions.

[0023] Furthermore, by setting valve bodies and flow sensors that correspond one-to-one with multiple branch pipelines, individual control of the top airbag and the two side airbags is achieved on the one hand, and the flow rate of gas entering the top airbag and the side airbags can be accurately obtained on the other hand, making it easier to grasp the clamping force of the top airbag and the side airbags on the product.

[0024] According to one embodiment of the present invention, the top airbag includes: a top first airbag and a top second airbag;

[0025] The top first airbag at least covers the receiving chamber.

[0026] Multiple top second airbags are disposed on the surface of the top first airbag facing the receiving chamber;

[0027] The branch pipeline includes multiple top sub-pipelines, the flow sensor includes a top flow sub-sensor that is configured one-to-one with the multiple top sub-pipelines, and the valve body includes a top sub-valve body that is configured one-to-one with the multiple top sub-pipelines.

[0028] The top first airbag and the multiple top second airbags are respectively connected to the top sub-pipes one by one.

[0029] Specifically, this embodiment proposes a top airbag implementation method. By setting the top airbag into two parts, a top first airbag and a top second airbag, the clamping force of the product can be adjusted. Fine-tuning of local airbag clamping can also be performed according to different product sizes and models.

[0030] It should be noted that the first airbag at the top serves as the basis for the top airbag, and its shape and size at least cover the receiving chamber in the direction of refrigerant flow. Meanwhile, the second airbag at the top is located on the surface of the first airbag facing the receiving chamber, and can be finely adjusted according to the actual size of the product.

[0031] It should also be noted that the first and second airbags at the top are each independently connected to a top sub-pipeline and a top flow sensor, which facilitates the control of inflation and monitoring of flow rate of the first and second airbags at the top.

[0032] Furthermore, the inflation volume of the top sub-tube connected to the first top airbag per unit time is greater than that of the top sub-tube connected to the second top airbag per unit time. That is, the first top airbag inflates rapidly, while the second top airbag inflates slowly relative to the first top airbag. This setting facilitates fine adjustment of the clamping force of the second top airbag on the product and also avoids damage to the product caused by the rapid expansion of the second top airbag.

[0033] Furthermore, the top sub-pipe connected to each top second airbag can also be controlled individually, thereby adjusting the inflation degree of each top second airbag and enabling rapid cooling for products in the same batch with different external dimensions.

[0034] According to one embodiment of the present invention, the top airbag includes: a top sub-airbag, wherein a plurality of the top sub-airbags at least cover the receiving chamber.

[0035] The branch pipeline includes multiple top sub-pipelines, the flow sensor includes a top flow sub-sensor that is configured one-to-one with the multiple top sub-pipelines, and the valve body includes a top sub-valve body that is configured one-to-one with the multiple top sub-pipelines.

[0036] The top sub-airbag is connected to the top sub-tube in a one-to-one correspondence.

[0037] Specifically, this embodiment proposes a top airbag implementation method. By setting the top airbag as multiple top sub-airbags evenly distributed along the refrigerant flow direction, the product clamping force can be adjusted, and the local airbag clamping can also be finely adjusted according to different product sizes and models.

[0038] It should be noted that each top sub-airbag is independently connected to a top sub-pipeline and a top flow sensor, which facilitates the control of inflation and monitoring of flow rate for each top sub-airbag.

[0039] Furthermore, the top sub-pipes connected to each top sub-airbag can also be controlled individually, thereby adjusting the inflation degree of each top sub-airbag and enabling rapid cooling for products in the same batch with different external dimensions.

[0040] According to one embodiment of the present invention, it further includes: a first pressure sensor, wherein the first pressure sensor is disposed on the side of the top second airbag or the top sub-airbag facing the receiving chamber.

[0041] Specifically, this embodiment proposes an implementation method for obtaining relevant pressure parameters generated by the top airbag squeezing the product. By setting a first pressure sensor on the side of the top second airbag or top sub-airbag facing the receiving chamber, the pressure parameters when the top airbag squeezes the product are obtained, avoiding the problem of product being squeezed and damaged due to excessive inflation of the top airbag.

[0042] According to one embodiment of the present invention, each of the side airbags includes: a first side airbag and a second side airbag;

[0043] The side-mounted first airbag at least covers the receiving chamber;

[0044] The second side airbag is disposed on the surface of the first side airbag facing the receiving chamber;

[0045] The branch pipeline includes multiple side sub-pipelines, the flow sensor includes side flow sub-sensors that are configured one-to-one with the multiple side sub-pipelines, and the valve body includes side sub-valve bodies that are configured one-to-one with the multiple side sub-pipelines.

[0046] The first side airbag and the plurality of second side airbags are respectively connected to the side sub-tubes one by one.

[0047] Specifically, this embodiment proposes an implementation method for a side airbag. By setting the side airbag into two parts, a first side airbag and a second side airbag, the clamping force of the product can be adjusted. Fine-tuning of the local airbag clamping can also be performed according to different product sizes and models.

[0048] It should be noted that the first side airbag serves as the basis for the side airbag, and its shape and size at least cover the receiving chamber in the direction of refrigerant flow. Meanwhile, the second side airbag is located on the surface of the first side airbag facing the receiving chamber, and can be finely adjusted according to the actual size of the product.

[0049] It should also be noted that the first side airbag and the second side airbag are each independently connected to a side sub-pipeline and a side flow sensor, which facilitates the control of inflation and monitoring of flow of the first side airbag and the second side airbag.

[0050] Furthermore, the inflation volume of the side sub-tube connected to the first side airbag per unit time is greater than that of the side sub-tube connected to the second side airbag per unit time. That is, the first side airbag inflates rapidly, while the second side airbag inflates slowly relative to the first side airbag. This setting facilitates fine adjustment of the clamping force of the second side airbag on the product and also avoids damage to the product caused by the rapid expansion of the second side airbag.

[0051] Furthermore, the side sub-pipes connected to each side second airbag can also be controlled individually, thereby adjusting the inflation degree of each side second airbag and enabling rapid cooling for products in the same batch with different external dimensions.

[0052] According to one embodiment of the present invention, each of the side airbags includes: a side sub-airbag, and a plurality of the side sub-airbags at least cover the receiving chamber.

[0053] The branch pipeline includes several side sub-pipelines, the flow sensor includes side flow sub-sensors that are configured one-to-one with the multiple side sub-pipelines, and the valve body includes side sub-valve bodies that are configured one-to-one with the multiple side sub-pipelines.

[0054] The side sub-airbags are connected to the side sub-tubes in a one-to-one correspondence.

[0055] Specifically, this embodiment proposes an implementation method for side airbags. By setting the side airbags as multiple side sub-airbags evenly distributed along the refrigerant flow direction, the clamping force of the product can be adjusted, and the local airbag clamping can also be finely adjusted according to different product sizes and models.

[0056] It should be noted that each side sub-airbag is independently connected to a side sub-pipeline and a side flow sensor, which facilitates the control of inflation and monitoring of flow for each side sub-airbag.

[0057] Furthermore, the side sub-pipes connected to each side sub-airbag can also be controlled individually, thereby adjusting the inflation degree of each side sub-airbag and enabling rapid cooling for products in the same batch with different external dimensions.

[0058] According to one embodiment of the present invention, it further includes: a second pressure sensor, the second pressure sensor being disposed on the side of the second side airbag or the side sub-airbag facing the receiving chamber.

[0059] Specifically, this embodiment proposes an implementation method for obtaining relevant pressure parameters generated by the side airbag squeezing the product. By setting a second pressure sensor on the side of the second side airbag or the side sub-airbag facing the receiving chamber, the pressure parameters when the side airbag squeezes the product are obtained, avoiding the problem of product being squeezed and damaged due to excessive inflation of the side airbag.

[0060] According to one embodiment of the present invention, it further includes: a protective plate assembly disposed on the surface of the top airbag and / or the side airbag on the side away from the receiving chamber, for restraining the displacement of the top airbag and / or the side airbag toward the side away from the receiving chamber.

[0061] Specifically, this embodiment proposes an implementation method that limits the expansion direction of the top airbag and / or side airbag during inflation. Since the top airbag and side airbag will expand and deform after inflation, in order to concentrate the expansion deformation of the top airbag and / or side airbag to one side of the receiving chamber and thus achieve product compression, this embodiment proposes to provide a protective plate assembly outside the top airbag and / or side airbag that can limit the displacement of the top airbag and / or side airbag.

[0062] According to one embodiment of the present invention, the guard plate assembly includes: a folding plate and a connector;

[0063] Multiple folded panels are spliced ​​together and laid on the surface of the top airbag and / or the side airbag away from the receiving chamber;

[0064] The two adjacent folding plates rotate about at least one of the connecting members.

[0065] Specifically, this embodiment proposes an implementation method for a protective plate assembly. By setting a connector to connect two spliced ​​folded plates, and the two spliced ​​folded plates can rotate around the connector, the constraint of displacement towards the side away from the receiving chamber is achieved during the inflation and expansion of the top airbag and / or side airbag. At the same time, it avoids the problem of damage or shortened service life caused by the top airbag and / or side airbag being squeezed by external force due to rigid connection.

[0066] According to one embodiment of the present invention, the connector is a damper with a self-resetting function.

[0067] Specifically, this embodiment proposes an implementation method for a connector. By setting a damper with a self-resetting function, the protective plate assembly can automatically return to its initial state during the exhaust process after the top airbag and / or side airbags have finished compressing the product.

[0068] A cold storage unit provided according to a second aspect of an embodiment of the present invention has at least one of the above-described rapid cooling devices.

[0069] Furthermore, the cold storage is used to place the products to be cooled on the tray.

[0070] According to one embodiment of the present invention, the product to be cooled is food.

[0071] Specifically, this embodiment proposes an implementation method for a product awaiting cooling.

[0072] According to one embodiment of the present invention, the product to be cooled is a fermented dairy product.

[0073] Specifically, this embodiment proposes another implementation method for products that need to be cooled.

[0074] A control method for the above-described rapid cooling device according to a third aspect of an embodiment of the present invention, the method comprising:

[0075] Obtain product information of the products to be cooled placed on the tray, and generate first rapid cooling parameters based on the product information;

[0076] Obtain the relative position information between the product to be cooled and the receiving chamber, and generate a second rapid cooling parameter based on the relative position information;

[0077] A rapid cooling decision is generated based on the first rapid cooling parameter and the second rapid cooling parameter.

[0078] According to one embodiment of the present invention, the step of obtaining product information of the product to be cooled and generating a first rapid cooling parameter based on the product information specifically includes:

[0079] Obtain at least the first parameter information carrying the type of the product to be cooled;

[0080] The historical rapid cooling records of the product to be cooled are determined based on the first parameter information;

[0081] If a first historical rapid cooling information corresponding to the first parameter information is matched in the historical rapid cooling record, then the first historical rapid cooling information is used as the first rapid cooling parameter.

[0082] If no first historical rapid cooling information corresponding to the first parameter information is matched in the historical rapid cooling record, then the second parameter information carrying the preset rapid cooling information of the product to be cooled is obtained, and the first rapid cooling parameter is generated according to the first parameter information and the second parameter information.

[0083] Specifically, this embodiment provides an implementation method for obtaining product information of products to be cooled. By obtaining the first parameter information that identifies the category or model of the product to be cooled, it can be known whether the same type and model of the product to be cooled has been subjected to rapid cooling operation in the historical rapid cooling record. If there is corresponding relevant information, the relevant rapid cooling operation parameters in that operation are directly retrieved and the relevant rapid cooling operation parameters are used as the first rapid cooling parameter.

[0084] Furthermore, for new products undergoing rapid cooling for the first time, a second parameter information is formed by acquiring the preset rapid cooling information of the product to be cooled, and a first rapid cooling parameter is generated based on the first parameter information and the second parameter information.

[0085] It should be noted that the first parameter information can be the category of the product to be cooled, the product identification QR code, and the product number, etc., which are the corresponding methods used to distinguish the product; the second parameter information is the relevant parameters preset by the product to be cooled during the rapid cooling process, such as the target temperature, air speed, and working time.

[0086] According to one embodiment of the present invention, the step of obtaining the relative position information of the product to be cooled and the receiving chamber, and generating a second rapid cooling parameter based on the relative position information, specifically includes:

[0087] Obtain the size information of the product to be cooled, and establish a three-dimensional model of the product based on the receiving chamber;

[0088] The top first inflation parameter of the top airbag and the side first inflation parameter of the side airbag are generated based on the product 3D model and the first parameter information.

[0089] The second rapid cooling parameter is generated based on the first inflation parameter at the top and the first inflation parameter at the side.

[0090] Specifically, this embodiment proposes a method for placing a product to be cooled into a receiving chamber. Since the product may deviate from a preset area during placement, or its height may be higher than that of a conventional product, or the products in the same batch may have irregular shapes, or the same batch may consist of multiple product models, all of these situations can lead to uncertainty in the relative position of the product within the receiving space. Therefore, to address these situations, this embodiment obtains a three-dimensional model of the product within the receiving chamber, and then establishes the first inflation parameters of the top airbag and the first inflation parameters of the side airbags in this rapid cooling operation. The second rapid cooling parameter is then generated using the first inflation parameters of the top and the first inflation parameters of the side airbags.

[0091] According to one embodiment of the present invention, the step of generating a rapid cooling decision based on the first rapid cooling parameter and the second rapid cooling parameter specifically includes:

[0092] A first rapid cooling strategy is generated based on the first rapid cooling parameter and the second rapid cooling parameter;

[0093] The first rapid cooling strategy is executed and the pressure parameters between the product to be cooled and the top airbag and the side airbag are continuously collected;

[0094] If the pressure parameter is less than or equal to the preset product pressure threshold, then the rapid cooling decision is generated according to the first rapid cooling strategy;

[0095] If the pressure parameter is greater than the preset product pressure threshold, then the top second inflation parameter of the top airbag and the side second inflation parameter of the side airbag are generated based on the preset product pressure threshold. A second rapid cooling strategy is generated based on the top second inflation parameter and the side second inflation parameter, and the rapid cooling decision is generated based on the second rapid cooling strategy.

[0096] Specifically, this embodiment proposes an implementation method for adjusting rapid cooling decisions based on pressure parameters during the rapid cooling process of a product to be cooled. Since there is a second rapid cooling parameter for the product to be cooled during the rapid cooling process, namely, the relative position of the product to be cooled and the receiving chamber may deviate from the expected plan, by obtaining the pressure parameters between the inflated top airbag and the side airbag and the product to be cooled in this case, it is ensured that the product to be cooled will not be squeezed, deformed or damaged due to the inflation and expansion of the top airbag and the side airbag during the rapid cooling process.

[0097] According to one embodiment of the present invention, after the step of generating a rapid cooling decision based on the first rapid cooling parameter and the second rapid cooling parameter, the method further includes:

[0098] Based on the rapid cooling decision, generate second historical rapid cooling information based on the first parameter information, and determine the historical rapid cooling record;

[0099] If no first historical rapid cooling information corresponding to the first parameter information is matched in the historical rapid cooling record, then the historical rapid cooling record based on the first parameter information is generated according to the second historical rapid cooling information.

[0100] If a first historical rapid cooling information corresponding to the first parameter information is matched in the historical rapid cooling record, a historical rapid cooling information sequence based on the first parameter information is generated according to the first historical rapid cooling information and the second historical rapid cooling information, and the historical rapid cooling record based on the first parameter information is generated according to the historical rapid cooling information sequence.

[0101] Specifically, this embodiment proposes an implementation method that stores the current rapid cooling operation to form a historical rapid cooling record for retrieval in subsequent rapid cooling operations.

[0102] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: The rapid cooling device, cold compartment and control method provided in the embodiments of the present invention, through the air pump assembly set independently connected to the air bag, realizes the adjustment of the size of the refrigerant flow space and the size of the clamping force on the product according to the product size, ensuring the close arrangement between products and achieving efficient rapid cooling.

[0127] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0128] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0129] Figure 1 and Figure 2 These are first and second schematic diagrams showing the assembly relationship of the rapid cooling device provided in an embodiment of the present invention. From... Figure 1 and Figure 2As can be seen from the present invention, the rapid cooling device includes a top airbag 10 and a side airbag 20, as well as a protective plate assembly 100 laid on the outside of the top airbag 10 and the side airbag 20. The protective plate assembly 100 may be laid on the outside of the top airbag 10 and the side airbag 20 completely, or it may be laid on a part of the outside of the top airbag 10 and the side airbag 20.

[0130] Furthermore, from Figure 1 It can also be seen that the top airbag 10, the side airbag 20 and the tray 30 form a receiving chamber to accommodate the product 110 to be cooled.

[0131] Furthermore, from Figure 2 It can also be seen that an air pump 50, a drainage unit 40, a main pipeline 60 and a branch pipeline 70 are installed outside the receiving chamber to inflate the top airbag 10 and the side airbag 20, as well as to extract or deliver gas into the receiving chamber.

[0132] It should be noted that, in Figure 1 and Figure 2 In this invention, no specific details such as the connection and support of each part are limited, such as the connection between the drainage unit 40 and the receiving chamber, the connection between the top airbag 10 and the side airbag 20, and the external support frame. In practical applications, this part can refer to conventional designs in the field.

[0133] Figures 3 to 6 These are first and second schematic diagrams showing the assembly relationship of the top airbag 10 and the side airbag 20 in the rapid cooling device provided in this embodiment of the invention. Figures 3 to 6 Various implementations of the top airbag 10 and the side airbags 20 in practical applications are shown.

[0134] It should be noted that, Figures 3 to 6 For ease of observation, the diagrams have been simplified accordingly. In practical applications, this does not represent the actual placement of the top airbag 10 and the side airbags 20. Figures 3 to 6 Completely consistent with what is shown in the image. Figures 3 to 6 This only provides an idea of ​​an implementation of the top airbag 10 and the side airbag 20. When applied in practice, the connection relationship between the top airbag 10 and the side airbag 20 can be set according to the actual situation. This part can refer to the conventional settings in the field.

[0135] Figure 7 and Figure 8 These are first and second schematic diagrams showing the assembly relationship of the valve body 80 and the flow sensor 90 in the top airbag 10 and the side airbag 20 in the rapid cooling device provided in this embodiment of the invention. Figure 7 and Figure 8As can be seen from this, the present invention proposes several implementations of the valve body 80 and the flow sensor 90 on the top airbag 10 and the side airbag 20.

[0136] It should be noted that the top sub-valve body 81, the side sub-valve body 82, the top flow sub-sensor 91, and the side flow sub-sensor 92 are all independently controlled in application, enabling local inflation and local fine-tuning of the top airbag 10 and the side airbag 20.

[0137] Furthermore, although Figure 7 and Figure 8 No indication Figure 7 and Figure 8 Whether the airbag is the top airbag 10 or the side airbag 20 is unclear, but since the top airbag 10 and the side airbag 20 have similar structures, they can be used interchangeably. Figure 7 and Figure 8 Only then was the process simplified.

[0138] It should also be noted that, regarding how the air pump 50 and valve body 80 achieve local adjustment of the top airbag 10 or the side airbag 20, in practical applications, the air pump 50 can be rotated in both directions while some parts of the valve body 80 are opened or closed to achieve local adjustment. Alternatively, the valve body 80 can be equipped with both air intake and exhaust functions. When the air volume in some areas of the top airbag 10 and / or the side airbag 20 is insufficient, the valve body 80 starts to intake air. When the air volume inside the top airbag 10 and / or the side airbag 20 is excessive, the valve body 80 starts to exhaust air, guiding the excess gas inside the top airbag 10 and / or the side airbag 20 into the top sub-pipe 71 and / or the side sub-pipe 72 to achieve local adjustment.

[0143] In some specific embodiments of the present invention, such as Figures 1 to 9 As shown, this solution provides a rapid cooling device, including: a top airbag 10, side airbags 20, a tray 30, a drainage unit 40, and an air pump 50 assembly; the top airbag 10 is disposed above the tray 30; the two side airbags 20 are respectively disposed on a pair of opposite sides of the tray 30; the drainage unit 40 is disposed on one side of another pair of opposite sides of the tray 30; the air pump 50 assembly is connected to the top airbag 10 and the two side airbags 20 respectively; wherein, the top airbag 10 facing the tray 30, the opposite side of the two side airbags 20, and the top side of the tray 30 surround and form a receiving chamber; the drainage unit 40 is used to introduce refrigerant into the receiving chamber; the air pump 50 assembly is used to adjust the gas content inside the top airbag 10 and the side airbags 20.

[0144] It should be noted that the present invention proposes a rapid cooling device to solve the defects of the prior art, which has poor adaptability to rapid cooling of products, difficulty in adjusting space according to specific products, thus making it difficult to improve cooling efficiency, wasting a large amount of energy consumption of the flow unit 40, and wasting a large amount of cold storage resources. The device can adjust the size of the refrigerant flow space according to the product size, ensure the close arrangement of products, and achieve efficient rapid cooling.

[0145] In one application scenario, the diversion unit 40 is a fan.

[0146] In some embodiments, the air pump 50 assembly includes an air pump 50, a main pipe 60, branch pipes 70, a valve body 80, and a flow sensor 90; the air pump 50 is connected to the main pipe 60; the main pipe 60 is connected to a plurality of branch pipes 70; the branch pipes 70 are respectively connected to the top airbag 10 and the side airbag 20; the plurality of valve bodies 80 are respectively arranged in a one-to-one correspondence with the plurality of branch pipes 70; the plurality of flow sensors 90 are respectively arranged in a one-to-one correspondence with the plurality of branch pipes 70.

[0147] Specifically, this embodiment proposes an air pump 50 assembly configuration scheme. By configuring the air pump 50, main pipeline 60, and branch pipeline 70, it is possible to deliver gas from the air pump 50 into the interior of the top airbag 10 and the side airbag 20, or the air pump 50 to extract gas from the interior of the top airbag 10 and the side airbag 20. Alternatively, the air pump 50 itself has both delivery and extraction functions, which can be selected according to the actual situation.

[0148] Furthermore, by setting valve bodies 80 and flow sensors 90 that correspond one-to-one with multiple branch pipes 70, individual control of the top airbag 10 and the two side airbags 20 is achieved on the one hand, and the flow rate of gas entering the top airbag 10 and the side airbags 20 can be accurately obtained on the other hand, making it easier to grasp the clamping force of the top airbag 10 and the side airbags 20 on the product.

[0149] In some embodiments, the top airbag 10 includes: a top first airbag 11 and a top second airbag 12; the top first airbag 11 at least covers the receiving chamber; a plurality of top second airbags 12 are disposed on the surface of the top first airbag 11 facing the receiving chamber; wherein, the branch pipe 70 includes a plurality of top sub-pipes 71, the flow sensor 90 includes a top flow sub-sensor 91 disposed one-to-one with the plurality of top sub-pipes 71, the valve body 80 includes a top sub-valve body 81 disposed one-to-one with the plurality of top sub-pipes 71; the top first airbag 11 and the plurality of top second airbags 12 are respectively connected to the top sub-pipes 71 one-to-one.

[0150] It should be noted that, as Figure 7 As shown, multiple top sub-tubes 71 can be set in the top first airbag 11 for inflation, thereby improving the inflation efficiency of the top first airbag 11.

[0151] Furthermore, although Figure 7 It is not explicitly stated whether the airbag is the top airbag 10 or the side airbag 20, but since the structures of the top airbag 10 and the side airbag 20 are similar, they can be interchangeable. Figure 7 Only then was the process simplified.

[0152] Specifically, this embodiment proposes an implementation of the top airbag 10. By setting the top airbag 10 into two parts, a top first airbag 11 and a top second airbag 12, the clamping force of the product can be adjusted. Fine-tuning of the local airbag clamping can also be performed according to different product sizes and models.

[0153] It should be noted that the top first airbag 11 serves as the basis for the top airbag 10, and its shape and size at least cover the receiving chamber in the direction of refrigerant flow. Meanwhile, the top second airbag 12 is disposed on the surface of the top first airbag 11 facing the receiving chamber, and can be finely adjusted according to the actual size of the product.

[0154] It should also be noted that the top first airbag 11 and the top second airbag 12 are independently connected to the top sub-pipeline 71 and the top flow sub-sensor 91, respectively, which facilitates the control of inflation and the monitoring of flow of the top first airbag 11 and the top second airbag 12.

[0155] Furthermore, the inflation volume of the top sub-tube 71 connected to the top first airbag 11 per unit time is greater than that of the top sub-tube 71 connected to the top second airbag 12 per unit time. That is, the top first airbag 11 inflates rapidly, while the top second airbag 12 inflates slowly relative to the top first airbag 11. This setting facilitates the fine adjustment of the product clamping force by the top second airbag 12 and also avoids damage to the product caused by the rapid expansion of the top second airbag 12.

[0156] Furthermore, the top sub-pipe 71 connected to each top second airbag 12 can also be controlled individually, thereby adjusting the inflation degree of each top second airbag 12 and achieving rapid cooling for products in the same batch with different external dimensions.

[0157] In some embodiments, the top airbag 10 includes: a top sub-airbag 13, wherein a plurality of top sub-airbags 13 at least cover the receiving chamber; wherein the branch line 70 includes a plurality of top sub-lines 71, the flow sensor 90 includes a top flow sub-sensor 91 configured in a one-to-one correspondence with the plurality of top sub-lines 71, and the valve body 80 includes a top sub-valve body 81 configured in a one-to-one correspondence with the plurality of top sub-lines 71; the top sub-airbags 13 are connected to the top sub-lines 71 in a one-to-one correspondence.

[0158] Specifically, this embodiment proposes an implementation method for the top airbag 10. By setting the top airbag 10 as a plurality of top sub-airbags 13 evenly distributed along the refrigerant flow direction, the product clamping force can be adjusted, and the local airbag clamping can also be finely adjusted according to different product sizes and models.

[0159] It should be noted that each top sub-airbag 13 is independently connected to a top sub-pipeline 71 and a top flow sensor 91, which facilitates the control of inflation and monitoring of flow rate for each top sub-airbag 13.

[0160] Furthermore, the top sub-pipeline 71 connected to each top sub-airbag 13 can also be controlled individually, thereby adjusting the inflation degree of each top sub-airbag 13 and achieving rapid cooling for products in the same batch with different external dimensions.

[0161] In some embodiments, it further includes: a first pressure sensor 14, which is disposed on the top second airbag 12 or the top sub-airbag 13 facing the receiving chamber.

[0162] Specifically, this embodiment proposes an implementation method for obtaining relevant pressure parameters generated by the top airbag 10 squeezing the product. By setting a first pressure sensor 14 on the side of the top second airbag 12 or the top sub-airbag 13 facing the receiving chamber, the pressure parameters when the top airbag 10 squeezes the product are obtained, avoiding the problem of product being squeezed and damaged due to the top airbag 10 being over-inflated.

[0163] In some embodiments, each side airbag 20 includes: a side first airbag 21 and a side second airbag 22; the side first airbag 21 at least covers the receiving chamber; the side second airbag 22 is disposed on the surface of the side first airbag 21 facing the receiving chamber; wherein, the branch pipe 70 includes a plurality of side sub-pipes 72, the flow sensor 90 includes side flow sub-sensors 92 disposed one-to-one with the plurality of side sub-pipes 72, the valve body 80 includes side sub-valve bodies 82 disposed one-to-one with the plurality of side sub-pipes 72; the side first airbag 21 and the plurality of side second airbags 22 are respectively connected to the side sub-pipes 72 one-to-one.

[0164] It should be noted that, as Figure 7 As shown, multiple side sub-tubes 72 can be provided in the side first airbag 21 for inflation, thereby improving the inflation efficiency of the side first airbag 21.

[0165] Furthermore, although Figure 7 It is not explicitly stated whether the airbag is the top airbag 10 or the side airbag 20, but since the structures of the top airbag 10 and the side airbag 20 are similar, they can be interchangeable. Figure 7 Only then was the process simplified.

[0166] Specifically, this embodiment proposes an implementation method for the side airbag 20. By setting the side airbag 20 into two parts, a first side airbag 21 and a second side airbag 22, the clamping force of the product can be adjusted, and the local airbag clamping can also be finely adjusted according to different product sizes and models.

[0167] It should be noted that the first side airbag 21 serves as the basis for the side airbag 20, and its shape and size at least cover the receiving chamber in the direction of refrigerant flow. Meanwhile, the second side airbag 22 is disposed on the surface of the first side airbag 21 facing the receiving chamber, and can be finely adjusted according to the actual size of the product.

[0168] It should also be noted that the first side airbag 21 and the second side airbag 22 are independently connected to the side sub-pipeline 72 and the side flow sub-sensor 92, respectively, which facilitates the control of inflation and the monitoring of flow of the first side airbag 21 and the second side airbag 22.

[0169] Furthermore, the inflation volume of the side sub-tube 72 connected to the side first airbag 21 per unit time is greater than that of the side sub-tube 72 connected to the side second airbag 22 per unit time. That is, the side first airbag 21 inflates rapidly, while the side second airbag 22 inflates slowly relative to the side first airbag 21. This setting facilitates the fine adjustment of the product clamping force of the side second airbag 22 and also avoids damage to the product caused by the rapid expansion of the side second airbag 22.

[0170] Furthermore, the side sub-pipes 72 connected to each side second airbag 22 can also be controlled individually, thereby adjusting the inflation degree of each side second airbag 22 and achieving rapid cooling for products in the same batch with different external dimensions.

[0171] In some embodiments, each side airbag 20 includes: a side sub-airbag 23, and a plurality of side sub-airbags 23 at least cover the receiving chamber; wherein, the branch line 70 includes a side sub-line 72, the flow sensor 90 includes a side flow sub-sensor 92 corresponding to a plurality of side sub-lines 72, and the valve body 80 includes a side sub-valve body 82 corresponding to a plurality of side sub-lines 72; the side sub-airbags 23 are connected to the side sub-lines 72 in a corresponding manner.

[0172] Specifically, this embodiment proposes an implementation method for the side airbag 20. By setting the side airbag 20 as a plurality of side sub-airbags 23 evenly distributed along the refrigerant flow direction, the clamping force of the product can be adjusted, and the local airbag clamping can also be finely adjusted according to different product sizes and models.

[0173] It should be noted that each side sub-airbag 23 is independently connected to a side sub-pipeline 72 and a side flow sensor 92, which facilitates the control of inflation and monitoring of flow for each side sub-airbag 23.

[0174] Furthermore, the side sub-pipes 72 connected to each side sub-airbag 23 can also be controlled individually, thereby adjusting the inflation degree of each side sub-airbag 23 and achieving rapid cooling for products in the same batch with different external dimensions.

[0175] In some embodiments, the system further includes a second pressure sensor 24, which is disposed on the side of the second side airbag 22 or the side sub-airbag 23 facing the receiving chamber.

[0176] Specifically, this embodiment proposes an implementation method for obtaining relevant pressure parameters generated by the side airbag 20 squeezing the product. By setting a second pressure sensor 24 on the side of the second side airbag 22 or the side sub-airbag 23 facing the receiving chamber, the pressure parameters when the side airbag 20 squeezes the product are obtained, avoiding the problem of product being squeezed and damaged due to the side airbag 20 being over-inflated.

[0177] In some embodiments, the system further includes a guard assembly 100 disposed on the surface of the top airbag 10 and / or the side airbag 20 away from the receiving chamber, for restraining the displacement of the top airbag 10 and / or the side airbag 20 toward the side away from the receiving chamber.

[0178] Specifically, this embodiment proposes an implementation method that limits the expansion direction of the top airbag 10 and / or the side airbag 20 during inflation. Since the top airbag 10 and the side airbag 20 will expand and deform after inflation, in order to concentrate the expansion deformation of the top airbag 10 and / or the side airbag 20 to one side of the receiving chamber and thus achieve product compression, this embodiment proposes to provide a protective plate assembly 100 outside the top airbag 10 and / or the side airbag 20 that can limit the displacement of the top airbag 10 and / or the side airbag 20.

[0179] In some embodiments, the protective panel assembly 100 includes: folding panels 101 and connectors 102; a plurality of folding panels 101 are laid on the surface of the top airbag 10 and / or the side airbag 20 away from the receiving chamber; two adjacent folding panels 101 rotate about at least one connector 102.

[0180] Specifically, this embodiment proposes an implementation method for the protective plate assembly 100. By providing a connector 102 that connects two spliced ​​folded plates 101, and the two spliced ​​folded plates 101 being able to rotate around the connector 102, the constraint of displacement towards the side away from the receiving chamber is achieved during the inflation and expansion of the top airbag 10 and / or the side airbag 20. At the same time, it avoids the problem of damage or shortened service life caused by the top airbag 10 and / or the side airbag 20 being subjected to large deformation due to external force compression caused by rigid connection.

[0181] In some embodiments, the connector 102 is a damper with a self-resetting function.

[0182] Specifically, this embodiment proposes an implementation of the connector 102. By setting a damper with a self-resetting function, the guard plate assembly 100 can automatically return to its initial state during the exhaust process after the top airbag 10 and / or the side airbag 20 have finished compressing the product.

[0183] In some specific embodiments of the present invention, this solution provides a cold storage chamber having at least one of the above-mentioned rapid cooling devices.

[0184] Furthermore, the cold storage also includes products 110 placed on pallets 30 to be cooled.

[0185] It should be noted that the embodiments of the present invention propose a cold storage to solve the defect of the existing technology where low-temperature products are difficult to be effectively and quickly cooled due to the uniform cooling of large cold storage shelves. It realizes the establishment of a complete rapid cooling solution according to the product type and space size, and achieves efficient and safe rapid cooling operation.

[0186] In some embodiments, the product to be cooled 110 is food.

[0187] Specifically, this embodiment proposes an implementation method for a product 110 to be cooled.

[0188] In some embodiments, the product to be cooled 110 is a fermented dairy product.

[0189] Specifically, this embodiment proposes another implementation method for the product 110 to be cooled.

[0190] In some specific embodiments of the present invention, such as Figure 10 As shown, this solution provides a control method for the above-mentioned rapid cooling device, the method comprising:

[0191] Obtain product information of the product 110 placed on tray 30 to be cooled, and generate first rapid cooling parameters based on the product information;

[0192] Obtain the relative position information between the product to be cooled 110 and the receiving chamber, and generate the second rapid cooling parameters based on the relative position information;

[0193] A rapid cooling decision is generated based on the first and second rapid cooling parameters.

[0194] It should be noted that the embodiments of the present invention propose a control method for a rapid cooling device to solve the defects of the prior art, such as low automation of rapid cooling of products and inability to formulate specific rapid cooling schemes according to products. This method enables the establishment of a complete rapid cooling scheme based on the product type and space size, thereby achieving efficient and safe rapid cooling operations.

[0195] In some embodiments, the step of obtaining product information of the product to be cooled 110 and generating a first rapid cooling parameter based on the product information specifically includes:

[0196] Obtain first parameter information for at least 110 types of products to be cooled;

[0197] Based on the first parameter information, determine the historical rapid cooling record of the product to be cooled, 110.

[0198] If a first historical rapid cooling information corresponding to the first parameter information is matched in the historical rapid cooling record, then the first historical rapid cooling information is used as the first rapid cooling parameter.

[0199] If no first historical rapid cooling information corresponding to the first parameter information is found in the historical rapid cooling record, then the second parameter information carrying the preset rapid cooling information of the product 110 to be cooled is obtained, and the first rapid cooling parameter is generated according to the first parameter information and the second parameter information.

[0200] Specifically, this embodiment provides an implementation method for obtaining product information of the product 110 to be cooled. By obtaining the first parameter information that identifies the category or model of the product 110 to be cooled, it can be known whether the same type and model of the product 110 to be cooled has been subjected to rapid cooling operation in the historical rapid cooling record. If there is corresponding relevant information, the relevant rapid cooling operation parameters in that operation are directly retrieved and the relevant rapid cooling operation parameters are used as the first rapid cooling parameter.

[0201] Furthermore, for a new product undergoing rapid cooling for the first time, a second parameter information is formed by acquiring the preset rapid cooling information of the product 110 to be cooled, and a first rapid cooling parameter is generated based on the first parameter information and the second parameter information.

[0202] It should be noted that the first parameter information may be the category to which the product 110 to be cooled belongs, the product identification QR code, and the product number, etc., which are the corresponding methods used to distinguish the product; the second parameter information is the relevant parameters preset by the product 110 to be cooled during the rapid cooling operation, such as the target temperature, wind speed, and working time.

[0203] In some embodiments, the step of obtaining the relative position information between the product to be cooled 110 and the receiving chamber, and generating a second rapid cooling parameter based on the relative position information, specifically includes:

[0204] Obtain the dimensional information of the product 110 to be cooled, and establish a 3D model of the product based on the receiving chamber;

[0205] The top first inflation parameters of the top airbag 10 and the side first inflation parameters of the side airbag 20 are generated based on the product's three-dimensional model and the first parameter information.

[0206] The second rapid cooling parameter is generated based on the first inflation parameter at the top and the first inflation parameter at the side.

[0207] Specifically, this embodiment proposes a method for placing the product 110 to be cooled into the receiving chamber. During the placement process, the product 110 may deviate from the preset area, or the height of the product 110 to be cooled may be higher than that of conventional products, or the shape of the products 110 in the same batch may be irregular, or the products 110 in the same batch may be composed of multiple models of products. These situations will lead to uncertainty in the relative position of the product 110 to be cooled within the receiving space. Therefore, in response to this situation, this embodiment obtains a three-dimensional model of the product 110 to be cooled within the receiving chamber, and then establishes the first inflation parameters of the top airbag 10 and the first inflation parameters of the side airbag 20 in this rapid cooling operation. Then, the second rapid cooling parameters are generated by the first inflation parameters of the top airbag 10 and the first inflation parameters of the side airbag 20.

[0208] In some embodiments, the step of generating a rapid cooling decision based on a first rapid cooling parameter and a second rapid cooling parameter specifically includes:

[0209] A first rapid cooling strategy is generated based on the first rapid cooling parameter and the second rapid cooling parameter.

[0210] The first rapid cooling strategy is implemented and the pressure parameters between the product to be cooled 110 and the top airbag 10 and the side airbag 20 are continuously collected;

[0211] If the pressure parameter is less than or equal to the preset product pressure threshold, a rapid cooling decision is generated according to the first rapid cooling strategy.

[0212] If the pressure parameter is greater than the preset product pressure threshold, the top second inflation parameter of the top airbag 10 and the side second inflation parameter of the side airbag 20 are generated based on the preset product pressure threshold. A second rapid cooling strategy is generated based on the top second inflation parameter and the side second inflation parameter, and a rapid cooling decision is generated based on the second rapid cooling strategy.

[0213] Specifically, this embodiment proposes an implementation method for adjusting the rapid cooling decision based on pressure parameters during the rapid cooling operation of the product 110 to be cooled. Since there is a second rapid cooling parameter for the product 110 to be cooled during the rapid cooling operation, that is, the relative position of the product 110 to be cooled and the receiving chamber may deviate from the expected plan, by obtaining the pressure parameters between the top airbag 10 and the side airbag 20 after inflation and the product 110 to be cooled in this case, it is ensured that the product 110 to be cooled will not be squeezed, deformed or damaged due to the inflation and expansion of the top airbag 10 and the side airbag 20 during the rapid cooling operation.

[0214] In some embodiments, after the step of generating a rapid cooling decision based on the first rapid cooling parameter and the second rapid cooling parameter, the method further includes:

[0215] Based on the rapid cooling decision, generate second historical rapid cooling information based on the first parameter information, and determine the historical rapid cooling record;

[0216] If no first historical rapid cooling information corresponding to the first parameter information is found in the historical rapid cooling record, then a historical rapid cooling record based on the first parameter information is generated based on the second historical rapid cooling information.

[0217] If a first historical rapid cooling record is matched with the first parameter information, a historical rapid cooling information sequence based on the first parameter information is generated based on the first historical rapid cooling information and the second historical rapid cooling information, and a historical rapid cooling record based on the first parameter information is generated based on the historical rapid cooling information sequence.

[0218] Specifically, this embodiment proposes an implementation method that stores the current rapid cooling operation to form a historical rapid cooling record for retrieval in subsequent rapid cooling operations.
