Description

Technical Field

[0001] This invention relates to a community-based intelligent meal preparation workstation and control method, specifically to a cabinet with a central control module and a heating system, which can be used for on-site instant cooking or timed on-site heating. Background Technology

[0002] With the fast pace of life, the demand for online distribution of fast food is huge, and ordering takeout has become a lifestyle for most people, especially urban white-collar workers, who often solve their lunch problem by ordering takeout. However, the existing takeout ordering methods are all the same: customers select restaurants and corresponding food items through mobile apps, the restaurants prepare the food, and then it is delivered to the customer via logistics. These foods are all pre-prepared in the restaurant and then delivered to the customer for immediate consumption. This method has many drawbacks. For example, it is well known that pre-prepared food, especially hot food, will greatly affect the taste after being packed in containers and transported for a certain period of time. Moreover, in the cold winters of northern regions, hot food will cool down during transportation, making heat preservation a major problem. In addition, many restaurants pre-cook many foods to avoid being overwhelmed with food during peak hours, and then simply reheat them before packaging and shipping. This kind of food not only tastes bad when it arrives at the customer's door, but if it is delivered too early, it is also prone to spoilage, affecting the customer's health.

[0003] In summary, the purpose of manual delivery is to fulfill individual orders (from station to person). This one-to-many delivery model inevitably suffers from high variability in delivery, long delivery times, low service efficiency, and high costs. Bento boxes have strict temperature requirements. Manual, insulated delivery has significant limitations in terms of delivery distance, service quality, service cost, and service safety. The service capacity of manual delivery restricts the distribution methods of bento boxes. This is also the fundamental reason why products from central kitchens and food production bases cannot directly and reliably serve individual online shoppers. Summary of the Invention

[0113] The meal distribution control method implemented using a community-based intelligent meal distribution workstation comprises the following steps:

[0114] (1) The product management terminal generates a food configuration list based on food demand data and matches the information in the configuration list to the configured food lunch boxes.

[0115] (2) The lunch box is placed into the matching delivery and distribution warehouse, and the delivery and distribution warehouse will carry out the on-site operation.

[0116] After receiving food demand information from users through the client, the cloud management center matches the corresponding delivery and fulfillment warehouse based on the community-based intelligent meal distribution workstation, generates food demand data, and then distributes it to the product management end and the logistics management end.

[0117] (2) In the process, the product management terminal configures raw food, semi-raw food or cooked food according to the food configuration list, and at the same time inputs the food configuration list information into the radio frequency code on the food container to complete the container configuration.

[0118] (2) In the steps, the delivery and payment warehouse on the community smart meal distribution workstation is placed in one of the following ways: Method 1: The logistics personnel deliver the food meal boxes to the community smart meal distribution workstation and enter the order number of the food configuration order or open the warehouse door by scanning the radio frequency code on the food meal box. The delivery personnel place the meal boxes into the delivery and payment warehouse and close the warehouse door.

[0119] Method 2: Logistics personnel deliver food containers to the community smart meal distribution workstation and enter the order number of the food preparation form or scan the RFID code on the food container to display the location of the corresponding delivery and distribution compartment. The delivery personnel then manually open the corresponding compartment door based on the displayed location, place the food container into the delivery and distribution compartment, and manually close the compartment door.

[0120] (1) The food demand data mentioned in the steps includes the specific details of the food, the location of the delivery warehouse that needs to be delivered, how to store it, and the time or time period when it needs to be eaten.

[0121] (2) On-site operations in the steps include refrigeration, freezing, cooking, on-site cooking in refrigeration or on-site heating in refrigeration environment at a time.

[0122] Advantages and effects:

[0123] This invention provides a community-based intelligent meal delivery workstation and meal delivery control method. This application combines the heating module with the delivery cabinet, so that the meal can be cooked or heated on-site at the user's end. This effectively solves the problems of poor taste, inability to guarantee the temperature when eating, and easy spoilage that exist in the previous takeout method of preparing finished products and then delivering them to the user.

[0124] This application enables centralized delivery of food from the same community smart food preparation workstation during peak ordering periods, eliminating the need for individual one-to-one delivery as in the past. This effectively solves the problems of low service efficiency and high costs associated with traditional delivery methods. Furthermore, because this application allows on-site cooking or heating at corresponding community smart food preparation workstations near users, it overcomes the significant service limitations of manual hot-keeping delivery in terms of delivery distance, service quality, service cost, and service safety.

[0125] In addition, this application system uses an APP + multi-temperature intelligent adaptation delivery service to link the pre-packaged daily meal supply chain, linking online and offline channels and industry collaboration to efficiently realize one-stop supply and intelligent circulation of a wide range of pre-packaged daily meal foods.

[0126] During the use of this invention, the user selects food on the client side. This application can effectively realize on-site cooking, which can effectively ensure the freshness and taste of the ingredients. At the same time, it can avoid the problem of food getting cold during transportation, thus effectively solving the problems that existed in the past.

[0127] With the rapid development of the internet economy, food delivery is no longer limited to breakfast, lunch, and dinner. The demand for chilled and frozen foods is also increasing daily. For example, people can order frozen dumplings, frozen fish and shrimp, and fresh fruits that require preservation. Currently, after such items are delivered to the designated location, if the customer cannot pick them up in time, the common practice is to add ice packs to the packaging and leave it at the designated location. This method can barely maintain the freshness of chilled and frozen foods for a short period of time, but as time goes by, especially in summer, this method cannot maintain the refrigeration time for very long. The result is that when the customer picks it up, many frozen ingredients have thawed, and refrigerated foods have spoiled, resulting in a poor customer experience. Therefore, these chilled and frozen foods need to be picked up by customers in a timely manner to ensure the freshness as much as possible. Chilled and frozen foods have strict temperature requirements for circulation; the service capacity of manual delivery limits the circulation methods of bento boxes and chilled and frozen foods; for chilled and frozen ingredients, this application can also further provide a continuous refrigerated or frozen storage environment.

[0128] Moreover, in the current logistics field, many items need to be stored in a temperature-controlled or heated environment. However, current equipment cannot effectively refrigerate, maintain, or heat stored items. It can only achieve passive insulation or refrigeration by sealing the container with insulation material. However, this method has a limited duration and cannot maintain the temperature for a long time, nor can it heat stored items that need to be heated. This application also solves this problem.

[0129] Furthermore, the online distribution of chilled and fresh foods and fast food has its own specific product quality requirements and consumer characteristics. Chilled and fresh foods require a cold-state preservation quality of -20 to 5 degrees Celsius; fast food requires a hot, ready-to-eat quality of no less than 65 degrees Celsius. To mitigate the quality risks of online purchases of such products, individual consumers' online orders are generally characterized by being dispersed, small in value, small in packaging, and high in frequency. In addition, these products also have a concentrated consumption requirement during mealtimes, meaning that everyone orders and receives food during mealtimes, which is relatively concentrated and can affect the customer experience. However, this application allows for on-site cooking or heating, enabling customers to order outside of mealtimes, and the logistics company can deliver food in advance, eliminating concerns about food cooling down as is common with traditional pre-prepared and delivered methods. Moreover, food from the same community smart meal delivery workstation can be centrally delivered within the same time period, achieving one-to-many delivery.

[0130] In summary, this application effectively solves the problems that existed in the past. Attached Figure Description

[0277] The community-based intelligent meal delivery workstation mainly consists of a modular heat source 3 and a cabinet 1. Cabinet 1 has one or more delivery and distribution compartments 2 (two or more are considered multiple). The modular heat source 3 corresponds to one or more delivery and distribution compartments 2 (meaning a heating module can be installed in only one delivery and distribution compartment 2, or in multiple delivery and distribution compartments 2). The modular heat source 3 can utilize existing heating technologies, such as electric heating, for example, its principle is similar to that of induction cookers, ceramic cookers, and heating wire heating. The number of modular heat sources 3 can be adapted to the number of inner boxes 16-1. For example, if there are two inner boxes 16-1, then... Figure 3 As shown, there are two module heat sources 3, and the two module heat sources 3 are independent of each other. Of course, the number of module heat sources 3 does not have to be adapted to the number of inner boxes 16-1. For example, when there is only one inner box 16-1, two module heat sources 3 can be used to cook and heat at the same time. Alternatively, there can be only one module heat source 3. In this case, if there are two inner boxes 16-1 (and if the food to be cooked in the two inner boxes 16-1 is the same), they can also be cooked and heated at the same time on one module heat source 3.

[0278] In addition, such as Figures 34 to 3 Figure 8 illustrates one form of the heating module, which includes a heating panel 37 and a heating assembly. The heating panel 37 can be made of cast aluminum, i.e., prepared using a die-casting aluminum process. The heating assembly is located on the back 37B of the heating panel 37. The heating assembly is constructed by covering a heating resistance wire 38A with ceramic 38B, and then placing them together inside the heating assembly housing 38. That is, from the inside out, the heating assembly consists of a heating resistance wire, ceramic, and the heating assembly housing 38. The heating assembly housing 38 is preferably a cast aluminum shell, prepared using a die-casting aluminum process. The heating assembly can be laid out in an "S" shape (e.g., ...). Figure 38-1 It can also be C-shaped (such as...) Figure 38-2 (As shown) or in a ring pattern, or any other equivalent laying method that serves the heating purpose. The heating element housing 38 has a mounting base 38-1 for connecting the external circuit to the resistance wire. The front side 37A of the heating panel 37 is coated with ceramic or Teflon; the heating element housing 38 and the heating panel 37 can be integrally die-cast, or the heating element can be mounted on the back side 37B of the heating panel 37 using mounting bolts 38-2 and pressure plates 38-3, etc. Specific installation methods are as follows: Figure 38-3As shown, the pressure plate 38-3 is pressed onto the heating assembly housing 38, and then the two ends of the pressure plate 38-3 are fixed to the heating panel 37 with the mounting bolts 38-2;

[0279] A temperature measuring device (temperature sensor, etc., directly using existing standard components) 38-4 (used to monitor the temperature of the heating panel 37) can also be installed on the back 37B of the heating panel 37. In use, the two mounting and positioning seats 38-1 are connected to the external circuit. At the same time, an over-temperature protection device (directly using existing standard components) can be connected to the external circuit connected to the resistance wire.

[0280] Additionally, the heating module 3 may also include a heat-insulating mounting plate 39, with the heating panel 37 mounted together with the heat-insulating mounting plate 39. Heat-insulating silicone 40 may be provided between the heating panel 37 and the heat-insulating mounting plate 39. The mounting method here can be as follows: Figure 34-3 As shown in Figure 7, the heat insulation mounting plate 39 has a mounting groove 39-1, and the heat insulation silicone 40 is a heat insulation silicone ring. The inner wall of the heat insulation silicone ring is provided with a stepped platform 40-1 (e.g., Figure 37-1 and Figure 37-2 As shown), the heating panel 37 is positioned at step 40-1 (as shown). Figure 37-2 As shown), the bottom of the heat-insulating silicone ring is provided with a bottom stepped platform 40-2 (as shown). Figure 37-2 As shown, the heat-insulating silicone ring is secured to the upper edge of the mounting groove 39-1 of the heat-insulating mounting plate 39 via the bottom stepped platform 40-2. The bottom plate of the mounting groove 39-1 has a wiring opening 39-2. In this case, for secure installation, a bolt mounting hole 38-5 with internal threads (not a through hole, but a groove) can be provided on the back side 37B of the heating panel 37. This bolt mounting groove can be a cylindrical internal thread groove directly opened on the inner wall of the back side 37B of the heating panel 37, or it can be a cylindrical internal thread mounting tube installed on the inner wall of the back side 37B of the heating panel 37. When fixing, the fastening bolt 39-3 passes through the bottom plate of the mounting groove 39-1 and extends into the bolt mounting hole 38-5, and engages with the bolt mounting hole 38-5 to complete the relative fixation between the heating panel 37, the heat-insulating mounting plate 39, and the heat-insulating silicone 40.

[0281] Further, it may include an exhaust pipe 4 (with a one-way valve), which is connected to one or more delivery and unloading compartments 2 of the setting module heat source 3 (meaning that one or more delivery and unloading compartments 2 of the setting module heat source 3 are connected to the exhaust pipe 4).

[0282] Further, it may include a refrigeration system (existing technology, similar to the refrigeration principle of air-cooled refrigerators); the refrigeration system is connected to one or more delivery and distribution warehouses (2), and the delivery and distribution warehouses (2) corresponding to the refrigeration system may be equipped with a heating module or may not have a heating module.

[0283] The exhaust pipe 4 and the refrigeration system can be installed either one or both.

[0284] For the refrigeration system, it also includes dampers, damper 5 is connected to the refrigeration system (that is, the delivery and unloading warehouse 2 connected to the refrigeration system is connected to the refrigeration system through the damper); damper 5 includes an inlet damper 5-1 and an outlet damper 5-2; inlet damper 5-1 (inlet damper 5-1 is connected to the inlet duct 5-3A, for example...) Figure 25-1 The upward-pointing duct on the right side is the air inlet duct. It is set up for one or more delivery and unloading warehouse positions 2. The air outlet 5-2 (air outlet 5-2 is connected to the return air duct 5-3B, for example) Figure 25-1 The downward-pointing pipe on the left is the return air duct, corresponding to one or more delivery and unloading compartments. The damper is typically an electric damper; the airflow is controlled by opening and closing the damper. This damper is similar to the electric dampers in commercially available air-cooled refrigerators; existing products will be directly procured.

[0285] like Figure 25-1 , Figure 25-4 and Figure 26 As shown, the refrigeration system mainly includes an evaporator 5-6, a circulating fan 5-5, a compressor 5-8, and a condenser 5-9 (as shown). Figure 25-1 and Figure 26 As shown, the evaporator 5-6, circulating fan 5-5, compressor 5-8, and condenser 5-9 can be located at the bottom of the entire community intelligent meal distribution workstation. The main connection method is as follows: compressor 5-8 is connected to condenser 5-9, condenser 5-9 is connected to evaporator 5-6, and evaporator 5-6 is connected to compressor 5-8. The location of evaporator 5-6 is connected to the cold air circulation path (this cold air circulation path is the path where cold air is delivered through air inlet duct 5-3A, enters delivery and distribution compartment 2 through air inlet door, exits from air outlet door of delivery and distribution compartment 2, and continues through return air duct 5-3B, passing through the evaporator and then circulating again). Figure 25-1 The arrows in the image show the path of the air circulation. Figure 25-4 As shown in the upper half), it can also be understood as: the evaporator 5-6 is placed in a pipe, and one end of the pipe (e.g.) Figure 25-1 and Figure 26 The right end shown in the diagram serves as the air outlet 5-10, which is connected to the circulating fan 5-5. The circulating fan 5-5 is then connected to the air inlet duct 5-3A (e.g., Figure 25-1The pipe pointing upwards on the right is the air inlet duct, and the other end of the pipe where the evaporator 5-6 is located (for example...) Figure 25-1 and Figure 26 The left end shown serves as the return air inlet 5-11, which connects to the return air duct 5-3B (e.g., Figure 25-1 The downward-pointing duct on the left is the return air duct; the circulating fan 5-5 draws cold air from the inlet duct into the delivery and unloading compartment 2, then returns through the return air duct to the evaporator for cooling before continuing the circulation. Figure 25-1 The entire arrow direction in the image indicates the air circulation path. Of course, to enhance the air circulation effect, another circulating fan can be connected at the return air inlet 5-11.

[0286] The circulating fan 5-5 delivers air through the air inlet duct 5-3A of the community intelligent meal distribution workstation to the air inlet door 5-1 of the delivery and distribution compartment 2. Then, it passes through the delivery and distribution compartment 2 and through the air outlet 5-2 to the return air inlet 5-11 of the evaporator 5-6. After passing through the evaporator, the air is recirculated. In Figure 25-1, 5-4 represents the insulation shell of the delivery and distribution compartment 2, i.e., the storage unit. Figure 26 5-13 is the drain outlet (the condensate drain outlet of the external environment. Some vapor in the outside air environment will condense around the evaporator and be discharged through this drain outlet to prevent water from accumulating in the gaps of the equipment). 5-12 is the insulation shell of the community intelligent meal distribution workstation. The refrigeration system is basically the same as the existing known refrigeration system in principle.

[0287] The community-based intelligent meal delivery workstation also includes a central control module. The opening of the dampers in the refrigeration system and the circulation of cold air (the operation of the circulating fan) are also controlled by the central control module.

[0288] When there are multiple delivery and fulfillment storage locations 2, the cabinet 1 is divided into one or more layers. When the cabinet 1 is a single layer, the multiple delivery and fulfillment storage locations 2 are arranged horizontally (i.e., as shown in the image). Figure 1 (As shown in the left-to-right direction); when cabinet 1 is multi-layered, the multi-layers are distributed from top to bottom, and one or more delivery and distribution warehouses 2 are set in each layer.

[0289] One type of cabinet:

[0290] When cabinet 1 is a single layer, and multiple delivery and unloading storage locations 2 are set up within this layer (this situation is applicable to places where vertical space (i.e., the vertical direction) is not very sufficient but horizontal space is relatively sufficient, or places where the overall demand is not particularly large; this method allows for multi-point arrangement in multiple locations), adjacent delivery and unloading storage locations 2 on the left and right are separated by partitions, and the air doors 5 are set up in one of the following ways:

[0291] The first method: There is only one set of air dampers (each set can have one or more air inlet dampers 5-1 and air outlet dampers 5-2), and air inlet damper 5-1 and air outlet damper 5-2 correspond to the same delivery and distribution warehouse 2 at the same time; in this case, the cold air in the corresponding delivery and distribution warehouse 2 can only be adjusted individually as needed;

[0292] The second method: There is only one set of air dampers (each set can have one or more inlet dampers 5-1 and outlet dampers 5-2). Inlet damper 5-1 corresponds to one of the delivery and distribution compartments 2, and outlet damper 5-2 corresponds to one of the other delivery and distribution compartments 2. The partition through which the airflow from inlet damper 5-1 to outlet damper 5-2 passes has openings for cold air circulation. (In this second method, if inlet damper 5-1 is set in the first delivery and distribution compartment 2 and outlet damper 5-2 is set in the second delivery and distribution compartment 2, then openings for cold air circulation are provided in the partition between the first and second delivery and distribution compartments 2; however, if inlet damper 5-1 is set in the second delivery and distribution compartment 2 and outlet damper 5-2 is set in the fifth delivery and distribution compartment 2...) Therefore, perforations for cold air circulation are provided in the partitions between the second and third delivery and loading compartments 2, the partitions between the third and fourth delivery and loading compartments 2, and the partitions between the fourth and fifth delivery and loading compartments 2; and so on in other cases.

[0293] The third method: There is only one set of air dampers, where the air inlet damper 5-1 is set for one of the delivery and unloading compartments 2 at one end; the air outlet damper is set for the other delivery and unloading compartment 2 at the other end (for example: if there are five delivery and unloading compartments 2 in total, then the air inlet damper 5-1 is set for the first delivery and unloading compartment 2 at the beginning, and the air outlet damper is set for the fifth delivery and unloading compartment 2 at the end). The partition between adjacent delivery and unloading compartments 2 has gaps for the flow of cold air; in this case, cold air can be adjusted for all delivery and unloading compartments 2 at the same time.

[0294] The fourth method: The air inlet door 5-1 is set for all delivery and loading compartments 2, and the air outlet door 5-2 is set for all delivery and loading compartments 2 (at this time, the partition between adjacent delivery and loading compartments 2 can also have gaps for the flow of cold air, or it can be left blank, because at this time each delivery and loading compartment 2 is equivalent to having an air inlet door and an air outlet door, which can be selected as needed); In this case, the cold air can be adjusted for multiple delivery and loading compartments 2. Taking the method where the partition between adjacent delivery and loading compartments 2 has no gaps as an example, the cold air of one of the delivery and loading compartments 2 can be adjusted individually, or the cold air of two or three of the delivery and loading compartments 2 can be adjusted as needed.

[0295] The fifth method: the air inlet door 5-1 is set up to correspond to a portion of the delivery and unloading compartment 2, and the air outlet door 5-2 is set up to correspond to a portion of the delivery and unloading compartment 2; (at this time, the partition through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass can have gaps for the flow of cold air, and the way the gaps are formed is the same as before);

[0296] In this case: a set of air dampers can be set for each of the two delivery and distribution compartments 2 (a total of two sets of air dampers, where each set includes both an air inlet and an air outlet; each set can contain one or more air inlets and one or more air outlets), or a set of air dampers can be set for each of the three delivery and distribution compartments 2 (a total of three sets of air dampers), and so on. For example, air inlet 5-1 is set for the first to third delivery and distribution compartments 2, and air outlet 5-1 is also set for the first to third delivery and distribution compartments 2. In this case, the partitions between the first and second delivery and distribution compartments 2 and between the second and third delivery and distribution compartments 2 can have openings for the flow of cold air, or they can be left empty.

[0297] For example, in this scenario: the air inlet door 5-1 is set to correspond to the first to third delivery and unloading compartments 2, and the air outlet door is set to correspond to the second to fourth delivery and unloading compartments 2. In this case, gaps for cold air circulation can be left in the partitions between the first and second delivery and unloading compartments 2, the partitions between the second and third delivery and unloading compartments 2, and the partitions between the third and fourth delivery and unloading compartments 2, etc. Of course, the air inlet door 5-1 can be set to correspond to the first to third delivery and unloading compartments 2, and the air outlet door can be set to correspond to the fourth to sixth delivery and unloading compartments 2, etc., in any combination. Then, gaps for cold air circulation can be left in the partitions through which the air path from the air inlet door 5-1 to the air outlet door 5-2 passes, and the gaps are formed in the same way as before. In this case, cold air regulation can be achieved for multiple delivery and unloading compartments 2 at the same time.

[0298] The sixth method: the air inlet door 5-1 is set up to correspond to one or part of the delivery and unloading warehouse 2; the air outlet door is set up to correspond to all the delivery and unloading warehouse 2; the partition through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass has a gap for the flow of cold air (the way the gap for the flow of cold air is formed on the partition is the same as before).

[0299] The seventh method: the air inlet door 5-1 is set for all delivery and distribution warehouses 2; the air outlet door is set for one or a part of the delivery and distribution warehouses 2. The partition through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass has a gap for the flow of cold air (the way the gap for the flow of cold air is formed on the partition is the same as before).

[0300] Eighth method: Air inlet 5-1 is set up for one delivery and distribution compartment 2; air outlet is set up for a portion of delivery and distribution compartments 2. The partition through which the air path from air inlet 5-1 to air outlet 5-2 needs to pass has a gap for cold air to flow through (the way the gap for cold air to flow through is the same as before); In this method: for example, an air inlet is set up in the first delivery and distribution compartment 2, and then air outlets can be set up in the first, second, third and fourth, etc., or an air inlet is set up in the second delivery and distribution compartment 2, and air outlets are set up in the third, fifth and sixth, etc., any combination that meets the above requirements is acceptable;

[0301] The ninth method: an air inlet door 5-1 is set up for a portion of the delivery and distribution compartments 2; an air outlet door is set up for one delivery and distribution compartment 2. A gap for cold air circulation is left in the partition through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass (the way the gap for cold air circulation is formed is the same as before. In this method: for example, an air outlet door is set up in the first delivery and distribution compartment 2, and then air inlets can be set up in the first, second, third, and fourth compartments, etc., or an air outlet door is set up in the second delivery and distribution compartment 2, and air inlets are set up in the third, fifth, and sixth compartments, etc. Any combination that meets the above requirements is acceptable.

[0302] In the above situations, there is not just one air inlet door and one air outlet door. That is to say, there can be one or more air inlets door, and similarly, there can be one or more air outlet doors.

[0303] In the above scenario, the air inlet can be installed at one or more of the following locations: the back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel location is for delivery and loading compartments 2 located at the left or right ends); the air outlet can be installed at one or more of the following locations: the back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel location is for delivery and loading compartments 2 located at the left or right ends, where the ends are as follows). Figure 2-1 (as shown on the left or right end), meaning the positions of the air inlet and air outlet can be as follows:

[0304] The air inlet door and the air outlet door can be installed on the back plate 8 at the same time, or on the bottom plate 7 at the same time, or on the side plate at the same time (this applies to the delivery and distribution warehouse (2) located at the end), or on the top plate at the same time, or on the partition at the same time.

[0305] Alternatively, the positions of the air inlet and air outlet can be arranged as follows:

[0306] The air inlet is located on the back panel, and the air outlet is located in a position other than the back panel; or the air inlet is located on the bottom panel, and the air outlet is located in a position other than the bottom panel; or the air inlet is located on the top panel, and the air outlet is located in a position other than the top panel; or the air inlet is located on the side panel (this applies to the delivery and unloading compartment 2 located at the end), and the air outlet is located in a position other than the side panel; or the air inlet is located on the partition, and the air outlet is located in a position other than the partition. In this configuration, the positions of the air inlet and air outlet can be interchanged, as long as the air inlet is connected to the air inlet duct 5-3A and the air outlet is connected to the return air duct 5-3B.

[0307] It should be noted that when cabinet 1 is a single layer and there is only one delivery and distribution compartment 2 in that layer, it is equivalent to a mini food preparation workstation for home use with heating, cooling, and ventilation functions (cooling function is optional). Of course, only one set of dampers is needed. In addition, in general, a mini food preparation workstation for home use can also be in the form of cabinet 1 being a single layer and there are only 2-3 delivery and distribution compartments 2 in that layer. In this case, it can meet the different taste needs of a family of three or more.

[0308] The partition described above has openings for the circulation of cold air. These openings can be made on the partition itself, or they can be the gap between the partition and the back panel of the delivery and loading compartment 2, the gap between the partition and the top panel of the delivery and loading compartment 2, the gap between the partition and the bottom panel of the delivery and loading compartment 2, or the gap between the partition and the compartment door. Any one or more of these options may be selected.

[0309] Cabinet Implementation Method Two:

[0310] When cabinet 1 is multi-layered and each layer has one delivery and distribution compartment 2, this is equivalent to a vertical, single-row community smart meal distribution workstation. It is suitable for locations with limited horizontal space but ample vertical space, or for areas with relatively low demand. This method can also be used for multi-point deployment in multiple locations. This method can be combined with one of the cabinet implementation methods for adaptive multi-point deployment. The air vent 5 in this method can also be set up in one of the following ways:

[0311] The first method: There is only one set of air dampers, with air inlet 5-1 and air outlet 5-2 corresponding to one delivery and distribution compartment 2. In this case, the cold air in the corresponding delivery and distribution compartment 2 can be adjusted individually as needed.

[0312] The second method: There is only one set of air dampers. Air inlet 5-1 corresponds to one of the delivery / receiving compartments 2, and air outlet 5-2 corresponds to one of the other delivery / receiving compartments 2. A perforation for cold air circulation is left in the floor plate through which the airflow from air inlet 5-1 to air outlet 5-2 passes. (In this method: for example, an air inlet is set in the first delivery / receiving compartment 2, and then an air outlet can be set in the second, third, or fourth delivery / receiving compartment 2, etc.; or an air inlet is set in the first delivery / receiving compartment 2, and an air outlet is set in the third, fifth, or sixth delivery / receiving compartment 2; that is, in this case, such as...) If an air inlet 5-1 is installed in the first upper delivery and unloading compartment 2, and an air outlet 5-2 is installed in the second upper delivery and unloading compartment 2, then a gap for cold air circulation will be left in the bottom plate between the first and second delivery and unloading compartments 2; if an air inlet 5-1 is installed in the second delivery and unloading compartment 2, and an air outlet 5-2 is installed in the fifth delivery and unloading compartment 2, then a gap for cold air circulation will be left in the bottom plate between the second and third delivery and unloading compartments 2, the bottom plate between the third and fourth delivery and unloading compartments 2, and the bottom plate between the fourth and fifth delivery and unloading compartments 2; and so on for other cases.

[0313] The third method: There is only one set of air dampers, in which the air inlet damper 5-1 is set to correspond to the upper or lower delivery and unloading compartment 2; the air outlet damper is set to correspond to the lower or upper delivery and unloading compartment 2 (the air inlet damper 5-1 and the air outlet damper each occupy one end, that is, one air inlet damper and one air outlet damper correspond to the upper delivery and unloading compartment 2, and the other corresponds to the lower delivery and unloading compartment 2, and the positions of them can be selected as needed). The bottom plate 7 between two adjacent delivery and unloading compartments 2 has gaps for the flow of cold air. In this case, cold air can be adjusted for multiple delivery and unloading compartments 2 at the same time.

[0314] The fourth method: the air inlet door 5-1 is set to correspond to all delivery and distribution warehouse positions 2, and the air outlet door 5-2 is set to correspond to all delivery and distribution warehouse positions 2 (in this case, the bottom plate through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to be left with a gap for the cold air to circulate, or it can be left empty).

[0315] The fifth method: Air inlet door 5-1 is set up for a portion of the delivery and distribution storage positions 2, and air outlet door 5-2 is set up for a portion of the delivery and distribution storage positions 2. (In this case, one set of air inlet doors can be set up for each of two delivery and distribution storage positions 2 (two sets of air in total), or one set of air inlet doors can be set up for each of three delivery and distribution storage positions 2 (three sets of air in total), and so on. For example, air inlet door 5-1 is set up for the first to third delivery and distribution storage positions 2.) The air outlet is also set for the first to third delivery and receiving compartments 2. In this case, the bottom plate can have gaps for the flow of cold air, or it can be left blank. In this case, it can also be set as follows: the air inlet 5-1 is set for the first to third delivery and receiving compartments 2, and the air outlet is set for the second to fourth delivery and receiving compartments 2. In this case, gaps for the flow of cold air can be left in the bottom plate between the first delivery and receiving compartment 2 and the second delivery and receiving compartment 2, the bottom plate between the second delivery and receiving compartment 2 and the third delivery and receiving compartment 2, and the bottom plate between the third delivery and receiving compartment 2 and the fourth delivery and receiving compartment 2. Of course, other combinations can also be used.

[0316] The sixth method: the air inlet door 5-1 is set up to correspond to one or part of the delivery and unloading warehouse 2; the air outlet door is set up to correspond to all the delivery and unloading warehouse 2; (the bottom plate through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass is left with a gap for the flow of cold air).

[0317] The seventh method: the air inlet door 5-1 is set up to correspond to all delivery and distribution warehouses 2; the air outlet door is set up to correspond to one or part of the delivery and distribution warehouses 2; (the bottom plate through which the air path from the air inlet door 5-1 to the air outlet door 5-2 needs to pass is left with a gap for the cold air to circulate);

[0318] Eighth method: Air inlet door 5-1 is set up for one delivery and distribution compartment 2; air outlet door is set up for a portion of delivery and distribution compartments 2; (the bottom plate through which the air path from air inlet door 5-1 to air outlet door 5-2 needs to pass is left with a gap for the flow of cold air).

[0319] The ninth method: an air outlet is set up for one delivery and distribution compartment 2; an air inlet is set up for a portion of the delivery and distribution compartments 2; (a gap is left in the bottom plate through which the air path from the air inlet 5-1 to the air outlet 5-2 passes to allow the cold air to circulate);

[0320] In the above situations, there is not just one air inlet door and one air outlet door. That is to say, there can be one or more air inlets door, and similarly, there can be one or more air outlet doors.

[0321] The air inlet door can be installed at one or more of the back panel 8, bottom panel 7, top panel, and side panel corresponding to the delivery and unloading warehouse 2; the air outlet door can be installed at one or more of the back panel 8, bottom panel 7, top panel, and side panel corresponding to the delivery and unloading warehouse 2.

[0322] The positions of the air inlet and air outlet can be as follows:

[0323] The air inlet and air outlet can be installed on the back panel 8, or on the bottom panel 7, or on the side panel, or on the top panel at the same time.

[0324] Alternatively, the positions of the air inlet and air outlet can be arranged as follows:

[0325] The air inlet is located on the back panel, and the air outlet is located in a position other than the back panel; or the air inlet is located on the bottom panel, and the air outlet is located in a position other than the bottom panel; or the air inlet is located on the top panel, and the air outlet is located in a position other than the top panel; or the air inlet is located on the side panel (this case applies to the delivery and unloading compartment 2 located at the end), and the air outlet is located in a position other than the side panel. In this configuration, the positions of the air inlet and air outlet can be interchanged, as long as the air inlet is connected to the air inlet duct 5-3A and the air outlet is connected to the return air duct 5-3B.

[0326] The bottom plate described above has openings for the circulation of cold air. These openings can be made on the bottom plate itself, between the bottom plate and the back plate of the delivery and loading compartment (2), between the bottom plate and the door, or between the bottom plate and the side plate of the delivery and loading compartment (2). Any one or more of these options may be selected.

[0327] Cabinet Implementation Method 3: Cabinet 1 is divided into multiple layers, with each layer having multiple delivery and unloading compartments 2. The air doors 5 are configured in one of the following ways:

[0328] When cabinet 1 is divided into multiple layers and each layer has multiple delivery and checkout compartments 2

[0329] The damper 5 can be set in one of the following ways:

[0330] The first method: the air doors are set up as a group, with the air inlet door 5-1 and the air outlet door corresponding to the same delivery and unloading warehouse position 2;

[0331] The second method involves a set of air dampers, with inlet damper 5-1 corresponding to one of the delivery and distribution compartments 2, and outlet dampers corresponding to one of the other delivery and distribution compartments 2. The airflow path from inlet damper 5-1 to outlet damper 5-2 must pass through a gap in the bottom plate or partition for cold air circulation, or the airflow path path must pass through both the bottom plate and partition for cold air circulation. This gap in the partition can be a hole in the partition itself, a gap between the partition and the back panel of the delivery and distribution compartment 2, or a gap between the partition and the top plate of the delivery and distribution compartment 2. It can also be the gap between the partition and the bottom plate of delivery and loading compartment 2, or the gap between the partition and the door, one or more of these can be selected; the bottom plate mentioned here has openings for cold air circulation, which can be openings set in the bottom plate itself, or the gap between the bottom plate and the back plate of delivery and loading compartment 2, or the gap between the bottom plate and the door, or the gap between the bottom plate and the side plate of delivery and loading compartment 2 (in this case, such as...). Figure 1 As shown, this refers to the delivery and fulfillment warehouse 2 at the left end, right end, or both ends; one or more of these can be selected.

[0332] The third method: Air dampers are set up on a horizontal layer basis. The layer with air dampers is one or more horizontal layers. Within each layer (multiple horizontal delivery and fulfillment storage locations 2), one set of air dampers is installed. (This means that, for example...) Figure 1 As shown, for example, if air dampers are set in the first, second and third horizontal layers, then the first layer corresponds to a separate set of air dampers, the second layer corresponds to a separate set of air dampers, and the third layer also corresponds to a separate set of air dampers. Among them, the air inlet 5-1 is set at one end of the delivery and loading compartment 2 of the same layer (for example, the left end); the air outlet is set at the other end of the delivery and loading compartment 2 (for example, the right end) (that is, the air inlet 5-1 and the air outlet 5-2 each occupy one end). The partition of the adjacent delivery and loading compartment 2 has gaps for the circulation of cold air (the gaps for the circulation of cold air mentioned here can be set on the partition itself, or it can be the gap between the partition and the back plate of the delivery and loading compartment 2, or the gap between the partition and the top plate of the delivery and loading compartment 2, or the gap between the partition and the bottom plate of the delivery and loading compartment 2, or the gap between the partition and the compartment door, and one or more of these can be selected).

[0333] The fourth method: Set the dampers by column, with one or more columns (e.g., ...). Figure 1The vertical direction shown is a column). In the column where the air doors are set, each column is equipped with a set of air doors. The air inlet door 5-1 is set for the upper or lower delivery and loading compartment 2; the air outlet door is set for the lower or upper delivery and loading compartment 2 (the air inlet door 5-1 and the air outlet door each occupy one end); the bottom plate 7 between two adjacent upper and lower delivery and loading compartments 2 has a gap for the circulation of cold air (the gap for the circulation of cold air in the bottom plate can be a gap set in the bottom plate itself, or it can be the gap between the bottom plate and the back plate of the delivery and loading compartment 2, or it can be the gap between the bottom plate and the door of the delivery and loading compartment 2, or the gap between the bottom plate and the side plate of the delivery and loading compartment 2 (this case is for the delivery and loading compartments 2 located at the left end, right end, or both ends), one or more of these can be selected).

[0334] The fifth method: Air inlet door 5-1 is set up for all delivery and unloading positions 2, and air outlet door 5-2 is set up for all delivery and unloading positions 2; (In this case, gaps for cold air circulation can be left in the base plate, partition, or both the base plate and partition. Of course, since air inlet door 5-1 and air outlet door are paired one-to-one, gaps may not be required; if gaps are required, it means that if the airflow from air inlet door 5-1 to air outlet door 5-2 only needs to pass through the base plate, then a gap for cold air circulation should be set in the base plate; if the airflow from air inlet door 5-1 to air outlet door 5-2 only needs to pass through the partition, then a gap for cold air circulation should be set in the partition.) If the air passage from the air inlet 5-1 to the air outlet 5-2 passes through both the base plate and the partition, then gaps for cold air circulation should be provided in both the base plate and the partition. These gaps in the partition can be provided on the partition itself, or they can be gaps between the partition and the back panel of the delivery and loading compartment 2, between the partition and the top panel of the delivery and loading compartment 2, between the partition and the base plate of the delivery and loading compartment 2, or between the partition and the compartment door; any one or more of these methods can be used. Similarly, these gaps in the base plate can be provided on the base itself, or they can be gaps between the base plate and the back panel of the delivery and loading compartment 2, between the base plate and the compartment door, or between the base plate and the side panels of the delivery and loading compartment 2 (this applies to the left, right, or both ends of the delivery and loading compartment 2); any one or more of these methods can be used.

[0335] The sixth method: Air inlet door 5-1 is set for all delivery and distribution warehouse positions 2, and air outlet door 5-2 is set for one or a portion of delivery and distribution warehouse positions 2; gaps for cold air circulation can be set in the bottom plate, partition, or bottom plate and partition through which the air path from air inlet door 5-1 to air outlet door 5-2 needs to pass; (This means that if the air path from air inlet door 5-1 to air outlet door 5-2 only passes through the bottom plate, then gaps for cold air circulation are set in the bottom plate; if the air path from air inlet door 5-1 to air outlet door 5-2 only passes through the partition, then gaps for cold air circulation are set in the partition; if the air path from air inlet door 5-1 to air outlet door 5-2 passes through both the bottom plate and the partition, then gaps for cold air circulation are set in both the bottom plate and the partition).

[0336] The seventh method: the air inlet door 5-1 is set to correspond to one or part of the delivery and unloading positions 2; the air outlet door is set to correspond to all delivery and unloading positions 2; the bottom plate, partition, or bottom plate and partition that the air passage from the air inlet door 5-1 to the air outlet door 5-2 needs to pass through can be provided with gaps for the flow of cold air (this means that if the air passage from the air inlet door 5-1 to the air outlet door 5-2 only passes through the bottom plate, then gaps for the flow of cold air are provided on the bottom plate; if the air passage from the air inlet door 5-1 to the air outlet door 5-2 only passes through the partition, then gaps for the flow of cold air are provided on the partition; if the air passage from the air inlet door 5-1 to the air outlet door 5-2 passes through both the bottom plate and the partition, then gaps for the flow of cold air are provided on both the bottom plate and the partition).

[0337] Eighth method: Air inlet 5-1 is set up corresponding to a portion of the delivery and unloading compartment 2; air outlet 5-1 is set up corresponding to a portion of the delivery and unloading compartment 2; the bottom plate, partition, or both the bottom plate and partition through which the airflow from air inlet 5-1 to air outlet 5-2 passes can be provided with openings for cold air circulation (this means that if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the bottom plate, then openings for cold air circulation are provided on the bottom plate; if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the partition...). If the air duct from the inlet door 5-1 to the outlet door 5-2 passes through both the bottom plate and the partition, then air ducts for cold air circulation should be provided on both the bottom plate and the partition. In this case, if the outlet door and the inlet door correspond to the same delivery and distribution compartment 2, then each delivery and distribution compartment 2 corresponds to both an inlet door and an outlet door. In this case, the air duct may not need to pass through the partition, bottom plate, etc., and therefore, the aforementioned air ducts do not need to be provided on the partition, bottom plate, etc. (Of course, in this case, it is also possible to provide air ducts).

[0338] The ninth method: Air inlet 5-1 is set up corresponding to one delivery / receiving compartment 2; air outlet 5-1 is set up corresponding to a portion of delivery / receiving compartments 2; perforations for cold air circulation can be provided in the base plate, partition, or both the base plate and partition through which the airflow from air inlet 5-1 to air outlet 5-2 passes (this means that if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the base plate, then perforations for cold air circulation are provided in the base plate; if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the partition, then perforations for cold air circulation are provided in the partition; if the airflow from air inlet 5-1 to air outlet 5-2 passes through both the base plate and the partition, then perforations for cold air circulation are provided in both the base plate and the partition).

[0339] The tenth method: An air outlet is set up corresponding to one delivery / receiving compartment 2; an air inlet is set up corresponding to a portion of the delivery / receiving compartments 2; openings for cold air circulation can be provided in the base plate, partition, or both the base plate and partition through which the airflow from air inlet 5-1 to air outlet 5-2 passes (this means that if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the base plate, then openings for cold air circulation are provided in the base plate; if the airflow from air inlet 5-1 to air outlet 5-2 only passes through the partition, then openings for cold air circulation are provided in the partition; if the airflow from air inlet 5-1 to air outlet 5-2 passes through both the base plate and the partition, then openings for cold air circulation are provided in both the base plate and the partition).

[0340] In the above situations, there is not just one air inlet door and one air outlet door. That is to say, there can be one or more air inlets door, and similarly, there can be one or more air outlet doors.

[0341] The air inlet can be installed at one or more of the following locations corresponding to the delivery and loading bay 2: back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel installation is for delivery and loading bays located at the ends). The air outlet can be installed at one or more of the following locations corresponding to the delivery and loading bay 2: back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel installation is for delivery and loading bays located at the ends). Figure 1 (As shown on the left and right ends), that is, the positions of the air inlet and air outlet can be as follows:

[0342] The air inlet door and the air outlet door can be installed on the back panel 8 at the same time, or on the bottom panel 7 at the same time, or on the side panel at the same time (this applies to the delivery and unloading compartment 2 located at the end), or on the top panel at the same time, or on the partition at the same time.

[0343] Alternatively, the positions of the air inlet and air outlet can be arranged as follows:

[0344] The air inlet is located on the back panel, and the air outlet is located in a position other than the back panel; or the air inlet is located on the bottom panel, and the air outlet is located in a position other than the bottom panel; or the air inlet is located on the top panel, and the air outlet is located in a position other than the top panel; or the air inlet is located on the side panel (this applies to the delivery and unloading compartment 2 located at the end), and the air outlet is located in a position other than the side panel; or the air inlet is located on the partition, and the air outlet is located in a position other than the partition. In this configuration, the positions of the air inlet and air outlet can be interchanged, as long as the air inlet is connected to the air inlet duct 5-3A and the air outlet is connected to the return air duct 5-3B.

[0345] Cabinet Implementation Method Four:

[0346] When cabinet 1 is divided into multiple layers, with some layers having one delivery and distribution compartment 2 and others having multiple delivery and distribution compartments 2, and one or more delivery and distribution compartments 2 are equipped with air inlets and one or more delivery and distribution compartments 2 are equipped with air outlets, in this case, the bottom plate, partition, or bottom plate and partition through which the air path from air inlet 5-1 to air outlet 5-2 needs to be provided with openings for the flow of cold air (this means that if air inlet 5-1...) If the air duct leading to the air outlet 5-2 only passes through the bottom plate, then a perforation for cold air circulation should be provided on the bottom plate. If the air duct leading to the air outlet 5-2 only passes through the partition, then a perforation for cold air circulation should be provided on the partition. If the air duct leading to the air outlet 5-1 passes through both the bottom plate and the partition, then a perforation for cold air circulation should be provided on both the bottom plate and the partition. In this case, if the air outlet and the air inlet correspond to the same delivery and receiving compartment 2, then each delivery and receiving compartment 2 corresponds to both an air inlet and an air outlet. In this case, the air duct may not need to pass through the partition, bottom plate, etc., and therefore, the perforation mentioned above does not need to be provided on the partition, bottom plate, etc. Of course, in this case, it is also possible to provide the perforation.

[0347] In the above situations, there is not just one air inlet door and one air outlet door. That is to say, there can be one or more air inlets door, and similarly, there can be one or more air outlet doors.

[0348] The air inlet can be installed at one or more of the following locations corresponding to the delivery and loading bay 2: back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel installation is for delivery and loading bays located at the ends). The air outlet can be installed at one or more of the following locations corresponding to the delivery and loading bay 2: back panel 8, bottom panel 7, top panel, partition, and side panel (the side panel installation is for delivery and loading bays located at the ends). Figure 1(As shown on the left and right ends), that is, the positions of the air inlet and air outlet can be as follows:

[0349] The air inlet and outlet doors can be installed simultaneously on the back panel 8, or simultaneously on the bottom panel 7, or simultaneously on the side panel (this applies to the delivery and distribution compartment 2 located at the end), or simultaneously on the top panel (here, the top panel, when the delivery and distribution compartment 2 has only one layer, is the top panel of the delivery and distribution compartment 2 as shown in Figure 2, which is the panel opposite to the bottom panel 7; when the delivery and distribution compartment 2 has multiple layers, the upper and lower layers are separated by the bottom panel 7. In this case, for the upper delivery and distribution compartment 2, the bottom panel 7 may be the bottom panel, and for the lower delivery and distribution compartment 2, the bottom panel 7 may also be the top panel of the lower delivery and distribution compartment 2), or simultaneously on the partition.

[0350] Alternatively, the positions of the air inlet and air outlet can be arranged as follows:

[0351] The air inlet is located on the back panel, and the air outlet is located in a position other than the back panel; or the air inlet is located on the bottom panel, and the air outlet is located in a position other than the bottom panel; or the air inlet is located on the top panel, and the air outlet is located in a position other than the top panel; or the air inlet is located on the side panel (this applies to the delivery and unloading compartment 2 located at the end), and the air outlet is located in a position other than the side panel; or the air inlet is located on the partition, and the air outlet is located in a position other than the partition. In this configuration, the positions of the air inlet and air outlet can be interchanged, as long as the air inlet is connected to the air inlet duct 5-3A and the air outlet is connected to the return air duct 5-3B.

[0352] Additionally, it should be noted that the above-mentioned methods for setting up dampers are not exhaustive.

[0353] The partition 6 between the two adjacent left and right delivery and unloading compartments 2 has gaps for cold air circulation in one or more of the following ways: First way: gap A between partition 6 and back panel 8; Second way: gap B between partition 6 and compartment door 9 of cabinet 1; Third way: holes set in partition 6; Fourth way: gap between partition 6 and bottom plate of (delivery and unloading compartment 2); Fifth way: gap between partition 6 and top plate of (delivery and unloading compartment 2).

[0354] The gaps in the bottom plate 7 between the two adjacent delivery and unloading compartments 2 mentioned above for the circulation of cold air can be one or more of the following: First, the gap between the bottom plate 7 and the back panel 8 of the cabinet 1; Second, the gap between the bottom plate 7 and the door 9 of the cabinet 1 (usually corresponding to the lower crossbeam 9-1); Third, the gaps are provided in the bottom plate 7; Fourth, the gap between the bottom plate 7 and the side panel 1-1 of the cabinet 1 (this usually refers to the delivery and unloading compartment 2 at the side end).

[0355] When there are multiple delivery and fulfillment storage locations 2, two horizontally adjacent delivery and fulfillment storage locations 2 are separated by a partition 6. The partition 6 can be permanently fixed (that is, directly fixed between two adjacent delivery and fulfillment storage locations 2) or flexibly fixed (that is, detachable, flip-up, or foldable, etc.). The flexibly fixed partition 6 can be one of the following types:

[0356] The first type of partition 6: The partition 6 is detachably inserted between two adjacent delivery and distribution compartments 2. A strip slot for inserting the partition 6 is provided between the two adjacent delivery and distribution compartments 2. The strip slot is provided on the bottom plate 7 and the top plate (referring to the top plate of the delivery and distribution compartment (2)). Figure 2-1 As shown, the plate above the base plate 7 is the top plate, or both the base plate 7 and the top plate bottom are set at the bottom. That is to say, there are three types of strip slots: the first is set only on the base plate 7, the second is set only on the bottom of the top plate. It should be noted that the so-called "top plate bottom" refers to the top plate of the delivery and distribution compartment 2 as shown in Figure 2, which is the plate opposite to the base plate 7, when the delivery and distribution compartment 2 has multiple layers, with the base plate 7 separating the upper and lower layers. In this case, for the upper... For the first delivery and loading storage location 2, the bottom plate 7 may be the bottom plate, while for the second delivery and loading storage location 2, the bottom plate 7 may also be the top plate of the second delivery and loading storage location 2. In the third method, the strip slot is set at the bottom of both the bottom plate 7 and the top plate. In use, the partition 6 is inserted into the strip slot between two adjacent delivery and loading storage locations 2 as a partition between the two delivery and loading storage locations 2. If the partition 6 is removed from the strip slot, then the two adjacent delivery and loading storage locations 2 are combined and transformed into a large delivery and loading storage location.

[0357] The second type of partition 6: Partition 6 is a structure that can be folded upwards or folded; that is, it folds or folds towards the top plate of the delivery and loading compartment 2, generally adhering to or nearly adhering to the top plate of the delivery and loading compartment 2; in the second type of partition 6, a folding component (e.g., hinge, pivot, or other component that can perform a similar function, any existing component that can perform the same function) is provided on the upper or rear side (the side closer to the back plate) of partition 6 to facilitate the upward folding or folding of partition 6, and the folding component on the upper part of partition 6 is connected to the top plate or back plate of delivery and loading compartment 2 (connection to the top plate is, for example, a hinge connecting the top of the partition to the top plate of delivery and loading compartment 2; while connection to the back plate is as follows...). Figure 2-8 As shown, for example, a shaft 00 is set on the back plate 8, and a bushing 001 or bearing is set above the partition 6 and fitted onto the shaft, so that the partition 6 can be folded upwards or folded. The folding component on the rear side of the partition 6 is connected to the back plate of the delivery and unloading compartment 2 (specific form as shown). Figure 2-9 As shown, taking the pivot as a folding component as an example, the pivot 00 in the figure is set on the back plate 8. A bushing 001 or bearing is set at the upper end of the back side of the partition and fitted on the pivot 00. Whether connected to the top plate or the back plate, it is convenient for the partition 6 to be folded upwards or folded.

[0358] The third type of partition 6: Partition 6 is a structure that can be folded downwards or folded; that is, it folds or folds towards the bottom plate 7 of the delivery and loading compartment 2, generally so that it can adhere to or nearly adhere to the bottom plate of the delivery and loading compartment 2 and cover the module heat source 3, although it can also leave the module heat source 3 exposed; in the third type of partition 6, the lower or rear side (the side near the back plate) of partition 6 is provided with a component that facilitates the downward folding of partition 6 (e.g., hinge, pivot, or other components that can play a similar role; any component that can play the same role in the prior art is acceptable); the folding component at the bottom of partition 6 is connected to the bottom plate or back plate of delivery and loading compartment 2 (for the connection with the bottom plate, taking a hinge as an example, the hinge connects the bottom of the partition and the bottom plate of delivery and loading compartment 2; and for the connection with the back plate, for example, a pivot is provided on the back plate 8). A bushing or bearing is provided below the partition 6 and fitted on the shaft to enable the partition 6 to be folded or flipped. The folding component on the rear side of the partition 6 is connected to the back plate of the delivery and unloading compartment 2 (taking the rotating shaft as the folding component as an example, the rotating shaft is set on the back plate 8, and a bushing or bearing is provided at the lower end of the rear side of the partition and fitted on the shaft). Whether connected to the bottom plate or the back plate, it is convenient for the partition (6) to be folded or flipped downwards. The specific form can be referred to the partition setting form in the above "second partition form". Compared with the above "second partition form", the setting position is changed to the lower part, or it can be seen as the "second partition form" reversed.

[0359] The fourth type of partition 6: The partition 6 is a structure that can be folded or flipped towards the back panel 8 (in this case, the position of the exhaust port connecting the exhaust pipe 4 and the delivery and unloading compartment 2 can be left open, that is, the exhaust port position should not be covered. A hole can be left on the partition 6 at the corresponding position, and the position of the exhaust port is from... Figure 4-1 As shown in the picture, this is the magnetic flexible connector 12, which is actually the exhaust port. In the fourth type of partition 6, a folding component (e.g., hinge, pivot, or other component that can perform a similar function, such as a hinge, pivot, or other component that can perform the same function in the prior art) is provided at the position where the rear end of the partition 6 (that is, the side near the back plate) connects with the back plate 8; or a folding component that can facilitate the folding of the partition 6 towards the back plate 8 is provided at the upper end, lower end, or both ends of the partition 6. In this case, taking the form of the folding component as the axis as an example, if the folding component is provided at the upper end of the partition 6, an axis can be provided at the position of the top plate near the rear back plate (the direction of the axis is perpendicular to the top plate), and then a bushing or bearing is provided at the upper end of the partition near the rear back plate, and fitted on the axis to realize the rotation of the partition; if the folding component is provided at the lower end of the partition 6, an axis can be provided at the position of the bottom plate near the rear back plate (the direction of the axis is perpendicular to the bottom plate), and then a bushing or bearing is provided at the lower end of the partition near the rear back plate, and fitted on the axis to realize the rotation of the partition.

[0360] In the second type of partition 6 described above, the top or back panel of the delivery and loading bay 2 (generally the upper part of the back panel, preferably near the top panel) is provided with a component that can temporarily restrict the partition 6 from flipping or folding downwards when the partition is folded upwards (that is, to temporarily fix the partition to the top or back panel); for example, a magnet for attracting the partition 6 (in this case, the partition 6 is made of iron, and the magnet can be set at the bottom of the top panel of the delivery and loading bay 2, so that the partition is attracted to the magnet after folding) or a hook 6-2 for hanging the partition 6, or other known existing components can be used. The component that can temporarily restrict the partition 6 from flipping downwards can be set on the top or back panel of the delivery and loading bay 2; such as Figure 2-4 As shown, hook 6-2 is installed on the top plate of delivery and unloading compartment 2 via pivot 6-3. Hook 6-2 can rotate around pivot 6-3. When the partition is folded upwards or folded down, hook 6-2 is turned to the position shown. Figure 2-4 At the position indicated by the dotted line, after the partition is folded upwards or folded to the state shown in the figure, flip hook 6-2 back and hook it onto the bottom of the partition, as shown. Figure 2-4 The solid line shown can also be replaced by a torsion spring on the pivot 6-3, so that when the hook 6-2 is bent to the desired position... Figure 2-4When the position is indicated by the dashed line, the torsion spring is engaged. After that, the hook 6-2 is released, and the torsion spring automatically hooks the bottom of the partition, as shown by the solid line in the figure.

[0361] Preferably, in the second type of partition 6, the lower part of the delivery and unloading compartment 2 (for example, it can be set on the bottom plate or at a lower position on the back plate) can also be provided with a component for temporarily restricting and fixing the partition 6 to maintain its upright state when the partition 6 is folded down or unfolded to an upright state. For example, a magnet (in this case, the partition 6 is iron, and the magnet is set on the bottom plate or the back plate, and the partition is attracted to the magnet) or a hook for hanging the partition 6, etc. In short, any component that can temporarily restrict the partition 6 to maintain its upright state; the component that keeps the partition 6 in this state is set on the back plate or the bottom plate.

[0362] In the third type of partition 6 described above, the component for temporarily fixing the partition 6 to maintain its upright state when it is upright can be located on the top plate or near the top of the back plate, preferably on the back plate close to the top plate. For example, a magnet 6-1 can be provided (in this case, the partition 6 is made of iron, and the magnet 6-1 is located at the bottom of the top plate or on the back plate of the delivery and unloading compartment 2, and the upper part of the partition 6 contacts and is attracted to the magnet when it is upright), or a hook for hanging the partition 6, a baffle for blocking the partition, or other known components that can temporarily prevent the partition 6 from falling down; the component for temporarily fixing the partition 6 to maintain its upright state is located on the top plate or the back plate of the delivery and unloading compartment 2; such as Figure 2-5 As shown, another form: the baffle 6-4 is installed on the top plate of the delivery and unloading compartment 2 via a rotating shaft 6-3. A torsion spring is installed on the rotating shaft 6-3. When the baffle 6 is folded upwards (as shown in the image), Figure 2-5 The partition 6 is rotated counterclockwise to stand upright. Move the baffle 6-4 to the position shown by the dotted line in the diagram. At this point, the torsion spring is engaged. When the partition 6 reaches the upright position shown in the diagram, a limiting block (a small protruding block or post on the left side will suffice to prevent the partition from rotating further) is placed on the bottom plate of the left side of the partition 6 to prevent it from folding over. Then release the baffle 6-4. Under the action of the torsion spring, the baffle 6-4 blocks the partition 6, as shown by the solid line in the diagram. At this point, the limiting block on the bottom plate of the left side of the partition 6 and the baffle 6-4 on the upper right side keep the partition upright. Or as shown... Figure 2-6As shown, another form: hook 6-2 is connected to shaft 6-3, allowing the hook to rotate. The upper end of shaft 6-3 is connected to the top plate of delivery compartment 2 via telescopic tube 6-5 (which may contain a tension spring) or a spring. After partition 6 is upright (taking counter-clockwise rotation as an example), pull down hook 6-2 and hook the partition (the upper part of the partition has holes for the hook to hook onto). If the telescopic tube contains a spring or the shaft 6-3 is directly connected to the spring, then a limit block to prevent excessive rotation of the partition can be omitted at the bottom left side of the partition. This is because when hook 6-2 is pulled down, the spring is stretched, and after hook 6-2 hooks the partition, the partition will be tightened under the action of the spring (and at this time, if...). Figure 2-6 As shown, the hook can also be installed on the left side of the partition (this is optional). Additionally, as... Figure 2-7 Another approach is to install a telescopic tube 6-5 (which may contain a push-out spring) on ​​the top plate of the delivery bay 2. When the partition is folded, pushing the telescopic tube upwards (compressing the spring if present) causes it to retract, making room for the partition to fold. When the partition is folded to an upright position (the diagram shows a counter-clockwise rotation to an upright position), the telescopic tube is released. At this point, under the influence of gravity or the push-out spring, the telescopic tube extends and blocks the partition 6. A limiting block (a small protruding block or post on the left side of the partition 6) is then placed on the bottom plate on the left side of the partition 6 to prevent further rotation. Alternatively, any other known technology can be used, which will not be elaborated here.

[0363] In the third type of partition 6, when the partition 6 is folded down to the bottom of the delivery and unloading compartment 2, the partition 6 can either cover the module heat source 3 of the delivery and unloading compartment 2 or expose the module heat source 3. Exposing the module heat source 3 means that the partition 6 can be provided with a cutout corresponding to the module heat source 3.

[0364] The front end of the delivery and fulfillment warehouse 2 is a warehouse door 9, which can be a revolving door, a sliding door (horizontal door), a swing door, a folding door, a roller shutter door, or a flip door.

[0365] Here, we take a sliding door as an example: The sliding door can be an electronic sliding door. A door frame 9-1 (the door frame is divided into an upper frame and a lower frame) is set at the front end of the delivery and unloading compartment 2. The upper frame, lower frame, or both frames of the door frame 9-1 are provided with a sliding groove or door frame guide rail (that is, the upper frame is provided with a sliding groove or door frame guide rail, the lower frame is provided with a sliding groove or door frame guide rail, or both the upper and lower frames are provided with a sliding groove or door frame guide rail; the door frame guide rail and the sliding groove have the same function, which is to allow the compartment door 9 to move along them). The compartment door 9 can move along the sliding groove or door frame guide rail.

[0366] The top frame, bottom frame, or both frames of the door frame 9-1 (meaning selectable, you can choose to set it only on the top frame, only on the bottom frame, or on both frames) are equipped with a toothed rack 9-3 or friction strip (e.g., Figure 5 As shown, the rack 9-3 or friction strip is generally installed on one side of the upper frame, one side of the lower frame, or one side of both frames of the door frame 9-1.

[0367] A motor 11 is installed on the door 9, corresponding to the rack 9-3 or friction strip (meaning the motor is positioned so that it corresponds to the rack 9-3 or friction strip; if the rack 9-3 or friction strip is on top, the motor is on top; if the rack 9-3 or friction strip is on the bottom, the motor is on the bottom; if there are racks 9-3 or friction strips on both the top and bottom, there can be motors on both the top and bottom). The output shaft of the motor 11 is equipped with an output gear 11-2 or an output friction wheel, which meshes with the rack 9-3 or friction strip. This means that if the door frame 9-1 has a rack 9-3, the output shaft of the motor 11 is the output gear 11-2, which meshes with the rack 9-3; if the door frame 9-1 has a friction strip, the output shaft of the motor 11 is the output friction wheel, which contacts and rubs against the friction strip. The friction wheel and friction strip are rough surfaces with small particles, and their movement is primarily achieved through friction.

[0368] Guide rails 9-2 are provided on the upper frame, lower frame, or both frames of the door frame (guide rails 9-2 are provided on the upper frame, lower frame, or both frames via guide rail seats 9-2-2). The upper end, lower end, or both ends of the door 9 are connected to the guide rails 9-2 via hanging guide sleeves 9-4, allowing the door 9 and hanging guide sleeves 9-4 to move relative to the guide rails 9-2 (that is, if only the upper end is provided with a guide rail, then the upper end of the door 9 is connected to the guide rail 9-2 via hanging guide sleeves 9-4; if the lower end is provided with a guide rail, then the lower end of the door 9 is connected to the guide rail 9-2 via hanging guide sleeves 9-4; if both the upper and lower ends are provided with guide rails, then both the upper and lower ends of the door 9 are connected to the guide rail 9-2 via hanging guide sleeves 9-4). A rack 9-3 or friction strip is provided on the side of the guide rails 9-2. The motor 11 is connected to the brush 11-1. The brush 11-1 is connected to the conductive rail 9-2 to obtain electrical energy, and the brush 11-1 can move relative to the rail 9-2.

[0369] This means that if the upper frame has a guide rail 9-2, the upper end of the compartment door 9 is connected to the guide rail 9-2 via a hanging guide sleeve 9-4 (in this case, an auxiliary guide rail or auxiliary slide rail can be set in the lower frame to further restrict the movement direction of the compartment door; alternatively, a slide rail can also be set in the upper frame, with the guide rail 9-2 located within that slide rail). If the lower frame has a guide rail 9-2, the lower end of the compartment door 9 is connected to the guide rail 9-2 via a hanging guide sleeve 9-4 (in this case, an auxiliary guide rail or auxiliary slide rail can be set in the upper frame to further restrict the movement direction of the compartment door; alternatively, a slide rail can also be set in the lower frame, with the guide rail 9-2 located within that slide rail). If the upper and lower frames of the door frame have guide rails 9-2 (in this case, auxiliary slide rails can be set in the upper or lower frame, or both upper and lower frames, with the corresponding guide rail 9-2 located within those slide rails), then both the upper and lower ends of the compartment door 9 are connected to the guide rail 9-2 via hanging guide sleeves 9-4; the hanging guide sleeve 9-4 is as follows: Figure 22 The diagram shows a sleeve fitted onto guide rail 9-2. Guide rail 9-2 has a rack 9-3 or friction strip on its side. Motor 11 is connected to brush 11-1, which contacts the conductive guide rail 9-2 to obtain electrical energy (the conductive guide rail 9-2 is connected to a power source). Brush 11-1 can move relative to guide rail 9-2. The movement of motor 11 is controlled by a central control module. The output shaft of motor 11 has an output gear 11-2 or output friction wheel, which engages with rack 9-3 (or friction strip). Motor 11 is preferably located inside the compartment door. The output gear 11-2 meshes with rack 9-3 to move the compartment door along guide rail 9-2, or the friction between the output friction wheel and friction strip moves the compartment door along guide rail 9-2.

[0370] The brush 11-1 is mounted on the guide sleeve 9-4, and can be mounted either outside or inside the guide sleeve 9-4. Figure 22 and 23 The image shows the configuration inside the guide sleeve, with one or more brushes 11-1.

[0371] The guide sleeve 9-4 is provided with a through hole 9-2-1 for the guide rail 9-2 to pass through. One or more brushes 11-1 are disposed in the through hole 9-2-1 and contact the guide rail 9-2. When there are multiple brushes 11-1, the multiple brushes 11-1 are evenly distributed around the axis of the guide rail 9-2 (e.g., Figure 23As shown, the included angle between two adjacent brushes 11-1 is the same. Rubber collision points 9-1-1 can be set on the upper frame, lower frame, or upper and lower frame of the door frame 9-1. The rubber collision points 9-1-1 can also be located at both ends of all the hanging guide sleeves 9-4 of each door (the two ends of all the hanging guide sleeves 9-4 are the left end of the leftmost hanging guide sleeve 9-4 and the right end of the rightmost hanging guide sleeve 9-4 if there are multiple hanging guide sleeves 9-4). The main purpose is to buffer when the door moves to the limit and prevent hard collision. Limit switches 9-1-2 can also be set on the upper frame, lower frame, or upper and lower frame. Their function is to control the movement of the door when the door is fully open and fully closed, so that the motor 11 stops moving, thereby stopping the door movement.

[0372] The rack 9-3 is set within the rack groove 9-3-2 without disengaging (meaning without disengaging, the rack groove 9-3-2 is as follows). Figure 20-2 As shown, this is a dovetail groove, or trapezoidal groove, which is a type of groove that gradually tapers from the bottom to the opening. The back of the rack 9-3 has a trapezoidal protrusion 9-3-1 that can be used with the dovetail groove. During installation, the trapezoidal protrusion 9-3-1 on the back of the rack 9-3 is inserted into the rack groove 9-3-2 from the side of the rack groove 9-3-2. Of course, it is not limited to the dovetail groove; any groove form that can play a similar role is acceptable, as long as it ensures that the rack 9-3 will not detach from the front opening of the rack groove 9-3-2. The rack and pinion groove 9-3-2 is set on the corresponding door frame. That is to say, if a rack is to be set on the upper frame, the rack and pinion groove 9-3-2 is set at the corresponding position on the upper frame, and the same applies to the lower frame. If the rack 9-3 is replaced by a friction strip, the friction strip can be directly fixed or it can cooperate with the rack and pinion groove 9-3-2 like the rack 9-3. The rack 9-3 can move relative to the rack and pinion groove 9-3-2 (it only needs to move a small distance, not too much. The main purpose is to achieve a buffering effect at the moment when the output gear 11-2 meshes with the rack 9-3 through the movement).

[0373] On one or both sides of rack 9-3 (e.g.) Figure 20-1 The left, right, or both sides of the middle are provided with cushioning elastic elements 9-5 (if it is in the form of a friction strip, you can choose to provide cushioning elastic elements 9-5 or not).

[0374] The buffer elastic element 9-5 generally comes in the following forms (taking a rack as an example):

[0375] Form 1: The buffer elastic element 9-5 can move together with the rack 9-3. In this case, the back of the buffer elastic element 9-5 is provided with an elastic element back protrusion 9-5-1 that can extend into and cooperate with the rack slide groove 9-3-2. Of course, the buffer elastic element 9-5 can also be directly set as... Figure 20-2 The back protrusion 9-5-1 is in the form of a buffer elastic element, which means that the back protrusion 9-5-1 in the figure is the buffer elastic element at this time. There is no front part. It is directly set in the rack groove 9-3-2, and then it contacts or connects with the trapezoidal protrusion 9-3-1 on the back of the rack 9-3.

[0376] In this configuration, the buffer elastic element 9-5 can be directly connected to the rack 9-3, or it can only contact the rack 9-3 during movement. For example, when the rack 9-3 moves forward, it pushes the buffer elastic element 9-5 to move a small distance until it reaches its limit. The buffer elastic element 9-5 then stops moving and buffers the rack 9-3 through its own deformation. The same applies when the rack moves backward. In the configuration where the buffer elastic element 9-5 is directly connected to the rack 9-3, after the movement stops, the elastic deformation of the buffer elastic element 9-5 buffers the rack 9-3.

[0377] Form 2: The buffer elastic element 9-5 is fixed, and there is a gap for movement between the rack 9-3 and the buffer elastic element 9-5. That is to say, in this case, after the rack 9-3 moves a small distance, it contacts the buffer elastic element 9-5, and the buffer is achieved through the buffer elastic element 9-5. The buffer elastic element 9-5 can be fixed in the rack groove 9-3-2, or it can be fixed at the side opening of the rack groove 9-3-2, sealing the side opening.

[0378] Form 3: The buffer elastic element 9-5 is set on both sides of the rack 9-3. One side of the buffer elastic element 9-5 is fixed, and the other side of the buffer elastic element 9-5 can move with the rack (9-3). The buffer elastic element 9-5 that can move with the rack 9-3 can be directly connected to the rack 9-3 or can touch the buffer elastic element 9-5 and move together when the rack 9-3 moves.

[0379] Form 4: The buffer elastic element 9-5 is set on both sides of the rack 9-3. The buffer elastic elements 9-5 on both sides are fixed and clamp the rack 9-3. That is to say, in this case, the rack 9-3 is in contact or connected with the buffer elastic element 9-5. So when the output gear 11-2 meshes with the rack 9-3, the deformation of the buffer elastic element 9-5 can buffer the movement of the rack 9-3.

[0380] In the aforementioned movable rack configuration, the main purpose is to prevent gear 11-2 from jamming with the rack by moving the rack pair a small distance. In configuration four, the jamming of gear 11-2 with the rack is directly prevented by the deformation of the buffer elastic element 9-5. If a gear meshing rack structure is used, the gear and rack may jam if the rack is fixed during operation. The movable rack configuration and the buffer elastic element 9-5 in configuration four both solve this problem by relieving the force of the gear pushing the rack, thus preventing the gear and rack from jamming during startup.

[0381] The buffer elastic element 9-5 is a spring or an elastic rubber strip (or a structure that serves the same purpose, such as a silicone block), or any other structure that can achieve the purpose; this is not an exhaustive list.

[0382] In the aforementioned structure with exhaust pipe 4, exhaust pipe 4 is connected to delivery and distribution compartment 2 via a self-adjusting and automatically closing interface. That is, in use, exhaust pipe 4 is temporarily connected to the internal exhaust duct of the meal box located in delivery and distribution compartment 2 via the self-adjusting interface.

[0383] The self-adjusting and automatic engaging interface is a magnetic flexible connector 12;

[0384] Embodiment 1 of the magnetic flexible connector 12:

[0385] This includes a flexible corrugated pipe 12-1 (e.g., made of silicone) and a magnetic clasp 12-1-2. The flexible corrugated pipe 12-1 is connected to the exhaust pipe 4 (the exhaust pipe either directly discharges or connects to the steam recovery system). In this method, the connection between the flexible corrugated pipe 12-1 and the exhaust pipe 4 can be as shown in Figure 6-1B, where a tapered pipe 4-5 is provided, with its rear end connected to the exhaust pipe 4. Then, the rear end of the flexible corrugated pipe 12-1 fits over the tapered part at the front end of the tapered pipe 4-5 to complete the connection. Alternatively, as shown in Figure 6-1C, a pipe 4-6 with a flange at the front end is provided, and an integral flange 12-1-F is provided at the rear end of the flexible corrugated pipe 12-1. The flange 12-1-F can be made of the same material as the flexible bellows 12-1. Then, the flange 12-1-F is clamped by two flange plates 4-6-1 and fixed with bolts to complete the connection. The rear end of the pipe 4-6 with flange is connected to the exhaust pipe 4. Of course, any other feasible method can be used (these methods belong to a type of fixed connection). The magnetic plate 12-1-2 is located at the front end of the flexible bellows 12-1.

[0386] The flexible corrugated tube 12-1 has a sleeve 12-1-1 at its front end, and the magnetic absorbing piece 12-1-2 is located inside the sleeve 12-1-1 (as shown in Figures 6, 27-1, and 27-2). The sleeve 12-1-1 can be fully enclosed or semi-enclosed. Full enclosed means that the entire outer periphery of the magnetic absorbing piece 12-1-2 is wrapped around it, while semi-enclosed means that the form shown in Figures 6 and 27-1 is used. In this case, a protective sleeve C1 can be put on the outer periphery of the magnetic absorbing piece 12-1-2. The magnetic absorbing piece 12-1-2 is a structure that can be attracted to the magnetic absorbing port 12-2 (with through holes) on the lunch box placed in the delivery and distribution compartment 2 when in use. That is to say, in actual use, a magnetic absorbing port 12-2 that can cooperate with the magnetic flexible connector 12 is set on the lunch box (that is, a magnetic absorbing port 12-2 is set at the front end of the lunch box exhaust channel). The specific setup can adopt any existing method. For example, a sleeve edge can be set, and the magnetic suction port 12-2 can be placed inside the sleeve edge. See the example of setting the magnetic suction piece 12-1-2 at the front end of the flexible corrugated tube 12-1. Of course, any other existing setup method can also be used (the configuration is up to you). The magnetic suction port 12-2 corresponds to the exhaust port of the exhaust channel on the lunch box. In use, the magnetic suction piece 12-1-2 and the magnetic suction port 12-2 automatically align and engage, connecting the exhaust pipe 4 with the exhaust channel inside the lunch box. The structure of the magnetic suction piece 12-1-2 that can engage with the magnetic suction port 12-2 means, for example, the magnetic suction piece is a magnet, and the magnetic suction port is an iron ring; or the magnetic suction piece is an iron ring, and the magnetic suction port is a magnet; or the magnetic suction piece and the magnetic suction port are magnets with opposite magnetic poles that can attract each other. In use, because the corrugated tube is a flexible, adjustable structure, it can automatically adjust its position according to the magnetic suction port being engaged, thereby achieving engagement.

[0387] The magnetic chuck 12-1-2 has a through hole 12-1-2-1, and the relationship between the magnetic chuck 12-1-2 and the sleeve edge 12-1-1 is one of the following forms:

[0388] The first type: The magnetic clasp 12-1-2 is fitted onto the flexible corrugated tube 12-1 and located inside the rim 12-1-1 (e.g., ...). Figure 27-1 (The edge of the sleeve is turned outwards);

[0389] The second form: The magnetic accumulator 12-1-2 is located inside the sleeve edge 12-1-1, and the through hole 12-1-2-1 of the magnetic accumulator 12-1-2 is connected to the flexible corrugated tube 12-1 (e.g., Figure 27-2 (The rim is turned inward).

[0390] The magnetic flexible connector 12 can also be configured in the following ways:

[0391] The back plate 8 of the delivery and unloading compartment 2 is provided with mounting holes. The flexible corrugated pipe 12-1 is installed in the mounting holes and is connected to the exhaust pipe 4. A gap C is left between the flexible corrugated pipe 12-1 and the side wall of the mounting hole to allow the flexible corrugated pipe 12-1 to move. A one-way valve can be installed at the rear end of the flexible corrugated pipe 12-1 to prevent the discharged steam from flowing back. This one-way valve can be directly adopted from existing components or can be adopted in the manner described later. Here, the connection between the mounting hole 35 and the back plate can be either fixed or detachable. A detachable connection will be described later, while a fixed connection means the mounting hole is fixed to the back plate. During installation, the flexible corrugated pipe 12-1 can first be connected to the exhaust pipe 4 (the connection method can be as described previously, see Figures 6-1B and 6-1C). Then, the mounting hole is fitted over the flexible corrugated pipe 12-1. The mounting hole can be directly fixed to the back plate via a flange or similar means. Alternatively, a sub-plate can be installed in front of the back plate 8, and the mounting hole can be connected to the sub-plate. The mounting hole is then fitted over the flexible corrugated pipe 12-1, and the sub-plate is fixed to the back plate. Of course, any other feasible fixing method can also be used.

[0392] A one-way valve (to prevent backflow of discharged steam) is installed behind the flexible bellows 12-1. The one-way valve can be configured as follows: the one-way valve includes a valve seat 4-1-2 and an openable valve disc 4-1-1 (the valve disc is a flexible sheet; both the valve seat and the valve disc can be made of silicone). The valve seat 4-1-2... A valve hole 4-1-2-1 is provided, which corresponds to the tail outlet 12-A-1 of the flexible bellows 12-1. A valve plate 4-1-1 is located inside the valve hole 4-1-2-1, and the diameter of the valve plate 4-1-1 (and the valve hole 4-1-2-1) is larger than the diameter of the tail outlet 12-A-1 of the flexible bellows 12-1 (so that the valve plate 4-1-1 can cover the tail outlet 12-A-1). A portion of the valve plate 4-1-1 is connected to the valve seat 4-1-2 (the inner wall of the valve hole 4-1-2-1) (for example, the edges of the valve plate 4-1-1 are connected to the valve seat 4-1-2 at points 4-A and 4-B, respectively; see...). Figure 4-2 and Figure 4-3 This allows the portion of valve plate 4-1-1 not connected to valve seat 4-1-2 to be lifted during steam discharge (e.g., ...). Figure 4-3 , 4-5 As shown in the schematic diagrams 4-6, when not in use, the circular flexible plate 4-1-1 covers the tail outlet 12-A-1. However, if gas backflow occurs, the valve plate 4-1-1 will be pressed closed; that is, as... Figure 4-2As shown in Figure 4-4, the valve plate 4-1-1 has a silicone elastic film structure and is deformable. When positive gas passes through, i.e., during exhaust, steam will be discharged from the tail end outlet 12-A-1 of the flexible bellows 12-1. The part of the valve plate 4-1-1 not connected to the valve seat is pushed open, and the valve plate 4-1-1 bulges and deforms, forming a ventilation gap AAA between it and the valve seat. Figure 4-2 and 4-4A The arrow in the middle indicates the direction of steam exhaust. Steam is transmitted through the gap. When it encounters the reverse airflow, valve plate 4-1-1 closes and locks tightly without gap. At this time, valve plate 4-1-1 covers the tail outlet 12-A-1, and the airflow cannot pass through, so that the gas does not flow back. Figure 4-3 The dotted line in the diagram represents the tail outlet 12-A-1. That is, the silicone elastic film structure 4-1-1 is deformable; in the forward direction, gas is transmitted through the gaps via the bulge deformation, and in the reverse direction, it closes and locks tightly without gaps, preventing gas from passing through.

[0393] Furthermore, the connection between the mounting hole 35 and the back plate can be detachable (e.g., Figure 6-1A Figure 6-1C shows a fixed connection between the mounting holes and the back plate. Figure 4-4B to Figure 4-22 As described in the detachable connection type, a mounting housing 36 is provided at the rear of the back plate. The mounting housing 36 is provided with an annular shoulder 36-1 (also called a retaining plate, which is the structure formed by the inner wall of the variable diameter section at the variable diameter section). The mounting hole 35 is positioned against the shoulder 36-1 during installation, and a sealing ring is provided between the mounting hole 35 and the shoulder 36-1.

[0394] The valve seat is locked at the rear of the mounting hole 35 (e.g., Figure 4-5 The image shows the rear part of the valve seat (which is fitted into the mounting hole 35) and the raised ring 4-1-2-1 on the valve seat protrudes from the rear end of the mounting hole 35. The raised ring 4-1-2-1 is designed to press against the annular shoulder 36-1 after installation (the raised ring 4-1-2-1 is made of silicone and can press against the annular shoulder (36-1) with an interference fit), thus playing a sealing role. In other words, the raised ring 4-1-2-1 at this time is equivalent to the aforementioned sealing ring.

[0395] Another form is where the valve seat is clamped between the mounting hole 35 and the annular shoulder 36-1 (in this case, the valve seat itself is equivalent to the aforementioned sealing ring).

[0396] The back plate 8 is provided with a mating through hole for mounting the mounting hole 35. The mounting housing 36 is mounted on the back of the back plate 8, and the front opening of the mounting housing 36 corresponds to the mating through hole, so that the mounting hole 35 can be installed in the mounting housing 36 through the mating through hole; the mating through hole (inner edge) has a notch 8-1-1 (e.g. Figure 4-11 , Figure 4-14 , Figure 4-15 , Figure 4-16 The number of notches is generally two or more, and the number and position of the fixing pins 35-1 correspond to the notches. Of course, one notch and one fixing pin can also be set. When there are multiple notches, all notches are evenly distributed. Evenly means that if there are two notches, the two notches are symmetrically positioned. If there are three or more notches, the angle between adjacent lines connecting the three or more notches to the center of the mating through hole is the same. Figure 4-11 An elastic (usually silicone) retainer 8-1-2 is formed by extending along the edge of the mating through hole 8-1, starting from one side of the notch 8-1-1. The retainer 8-1-2 (from head to tail) extends along the edge of the mating through hole 8-1, meaning its inner wall can be aligned with the inner wall of the mating through hole 8-1. The inner wall of the retainer 8-1-2 and the inner wall of the mating through hole 8-1 can be a single, integral structure. Figure 4-11 , Figure 4-14 , Figure 4-15 As shown, where Figure 4-15 It can be a one-piece structure; or the pad 8-1-2 can be offset outwards from the inner wall of the through hole 8-1 (outwards means radially outwards from the center of the through hole 8-1). Additionally, a limiting post 8-1-3 can be set on the other side of the notch 8-1-1 to prevent incorrect rotation. A limiting structure is provided at the tail of the pad 8-1-2; this limiting structure can be a slot 8-1-2-1, a limiting protrusion 8-1-2-2, or both. When both slot 8-1-2-1 and limiting protrusion 8-1-2-2 are set simultaneously, they can be set separately (meaning separated by a distance), thus providing a double protection against excessive rotation. For example, if the limiting protrusion 8-1-2-2 is located after the slot 8-1-2-1, then if the fixing pin 35-1 rotates excessively beyond the slot 8-1-2-1, it will also be stuck at the protrusion 8-1-2-2. The slot 8-1-2-1 and the limiting protrusion 8-1-2-2 can also be connected but arranged sequentially. Here, "connected" means, for example... Figure 4-15In the configuration where the slot 8-1-2-1 is in front and the limiting protrusion 8-1-2-2 is behind, the rear side of the slot 8-1-2-1 is the front side of the limiting protrusion 8-1-2-2, and the two sides overlap to form surface DE. The function of the limiting structure is twofold: firstly, to restrict the excessive rotation of the fixing pin 35-1, meaning that the fixing pin 35-1 stops rotating when it reaches the position of the limiting structure; secondly, the slot 8-1-2-1 can lock the fixing pin 35-1, thus providing a limiting and anti-rotation function.

[0397] The thickness direction SS of the pad 8-1-2 extends from front to back, i.e. Figure 4-15 The direction of the arrow shown is also the axial direction of the through hole 8-1; the "front" mentioned here refers to the side where the delivery and unloading compartment 2 is located, and the width of the pad 8-1-2 extends outward along the radial direction of the through hole 8-1.

[0398] The outer wall of the mounting hole 35 is provided with a fixing pin 35-1. The fixing pin 35-1 is designed to pass through the notch 8-1-1 during use and to lock the pad 8-1-2 after rotation. It is generally advisable to lock it in the slot 8-1-2-1.

[0399] Furthermore, as an extension, the front end of the mounting hole 35 can also be provided with a structure that facilitates controlling the rotation of the mounting hole 35. (The structure that facilitates controlling the rotation of the mounting hole 35 can be as follows...) Figures 4-15 to 4-18 The two symmetrical sockets 35-2 shown can be adjusted as needed, such as more than two. Generally, installing two is sufficient for normal use, but one is also possible, although operation is slightly more difficult with only one, but it does not affect the functionality. The bottom of the socket 35-2 is closed, as shown below. Figure 4-18 As shown, when using it, first pass the entire mounting hole 35 through the mating through hole 8-1, and then use two cylindrical tools 38 (such as...) Figure 4-17 Insert the pin 35-1 into the socket 35-2 and press it against the mounting hole 35 so that the retaining pin 35-1 passes through the notch 8-1-1 and presses against the socket 35-2, so that the retaining pin 35-1 is located at the rear of the retaining pad 8-1-2 (that is, as shown). Figures 4-8 to 4-10 as well as Figure 4-12 (As shown on the left), then rotate to make the fixing pin 35-1 engage in the slot 8-1-2-1. At this time, the raised vertical ring 4-1-2-1 presses against the annular shoulder 36-1, forming an interference fit. Alternatively, the rear end of the mounting hole 35 and the annular shoulder 36-1 can clamp the valve seat in the middle (or clamp another sealing ring). This completes the installation of the mounting hole. At this time, the raised vertical ring 4-1-2-1 presses against the shoulder 36-1, completing the seal. The sealing ring 40 is also clamped between the mounting hole 35 and the mating through hole 8-1. In addition, if it is for ease of operation, such as Figure 4-17As shown, the two cylindrical tools 38 can also be connected by a horizontal handle 39. Alternatively, a strip groove 35-2A can be used to facilitate control of the rotation of the mounting hole 35, as shown. Figure 4-19 Similar to the slot on a self-tapping screw head, the insert 38A, adapted to the slot 35-2A, is inserted into the slot and presses against the mounting hole 35, causing the retaining pin 35-1 to pass through the notch 8-1-1. Rotation then causes the retaining pin 35-1 to engage with the slot 8-1-2-1, completing the mounting hole installation. Alternatively, for ease of operation, such as... Figure 4-19 As shown, the two inserts 38A can also be connected by a horizontal handle 39A.

[0400] Additionally, a sealing ring 40 can be installed between the front side wall of the mounting hole 35 and the mating through hole 8-1 (the sealing ring can be installed in front of the fixing pin 35-1, such as...). Figure 4-18 As shown in Figures 4-4 and 4-18, the sealing ring 40 can be pre-fitted onto the front side wall of the mounting hole 35, or a groove for fitting the sealing ring can be provided on the front side wall of the mounting hole 35.

[0401] The back side mentioned above is in contrast to the front side. The front side, for example, is the side of the back panel that faces the delivery and checkout compartment 2, which is the side that faces the lunch box when in use. The other side is the back side. The same applies to other components.

[0402] like Figures 4-4B to 4-7As shown, one installation method for the flexible corrugated pipe 12-1 (this is not an exhaustive list, but only one of several possible methods): The rear end of the flexible corrugated pipe 12-1 is provided with an outwardly turned (radially extended) mounting flange 12-1-3 (also made of silicone, integral with the corrugated pipe), and an inner clamping piece 35-01 (an annular piece with a through hole, the through hole connecting to the tail outlet 12-A-1 of the flexible corrugated pipe 12-1) is provided inside the mounting hole 35. The inner clamping plate 35-01 and the outer clamping plate 35-02 (which is an annular plate with a through hole that connects to the tail outlet 12-A-1 of the flexible bellows 12-1) are connected. The mounting flange 12-1-3 is clamped between the inner clamping plate 35-01 and the outer clamping plate 35-02. In addition, the rear inner wall of the mounting hole 35 is provided with a mounting groove 35-5, which is located behind the outer clamping plate 35-2 and close to it. The valve seat 4-1-2 includes a raised vertical ring 4-1-2-1 and a transverse flange ring 4-1-2-2. The raised vertical ring 4-1-2-1, the transverse flange ring 4-1-2-2 and the valve plate 4-1-1 are all made of elastic material (such as silicone, etc., and are all one piece). The transverse flange ring 4-1-2-2 is located at the raised vertical ring 4-1-2-1. The outer side of the transverse flange ring 4-1-2-2 (or, relative to the outer wall of the raised vertical ring 4-1-2-1, the transverse flange ring 4-1-2-2 extends outward and protrudes, so that the outer wall of the raised vertical ring 4-1-2-1 and the outer wall of the transverse flange ring 4-1-2-2 form a stepped protrusion) is used. When in use, the transverse flange ring 4-1-2-2 is installed in the mounting groove 35-5, so that the valve seat is close to the outer clamp 35-02. Of course, the above installation method is only an example to illustrate one way of implementing the technical means, and any other feasible method can be used for installation.

[0403] The bottom inner wall 36-2A of the rear pipe 36-2 (generally referring to the part behind the shoulder 36-1, which is connected to the exhaust pipe 4) of the housing 36 shall not be higher than the bottom inner wall 4-1-2-1A of the raised ring 4-1-2-1. This is to prevent the accumulation of condensate.

[0404] The inner wall of the raised vertical ring 4-1-2-1 is flared. (That is, the inner diameter gradually increases from front to back. Here, "from front to back" refers to the direction from the valve plate towards the rear of the pipe 36-2. In other words, the front is the side closer to the delivery and unloading compartment 2, or as...) Figure 4-5 As shown, the side closer to the back plate 8 will form a sloping structure on the bottom inner wall 4-1-2-1A of the raised ring 4-1-2-1. This slope extends downward from the valve plate direction to the bottom inner wall 36-2A of the rear pipe 36-2 to prevent the accumulation of condensate.

[0405] Alternatively, the structure at the aforementioned through hole 8-1 can also be implemented in one of the following ways. The following ways are merely examples of feasible methods and are not exhaustive; any other existing and conceivable installation method can also be used:

[0406] Method 1 (e.g.) Figures 4-4B to 4-8 as well as Figure 4-15 , Figure 4-16 ,as well as Figure 4-20 to Figure 4-22 As shown): A circular hole ABB is made on the back plate 8, and then the pre-made silicone part AB is placed into the circular hole. The silicone part AB is provided with a variable diameter through hole, that is, the inner diameter of the front through hole is smaller than the inner diameter of the rear through hole, so that the rear inner wall of the silicone part AB expands outward to form a stepped shoulder AB-1. At this time, the inner diameter of the front through hole of the variable diameter through hole is smaller than the diameter of the circular hole ABB of the back plate 8. The front through hole (the part with the smaller inner diameter) of the variable diameter through hole is the mating through hole 8-1. The space formed by the rear through hole (the part with the larger inner diameter) of the variable diameter through hole is the space DA to accommodate the rotation of the fixing pin 35-1. The front end face of the silicone part AB forms a stepped shoulder AB-1, which is used to lock at the through hole ABB of the back plate.

[0407] At this point, the front through hole of the reducing diameter is essentially formed by a rubber ring. A notch is set on the rubber ring, and a retaining pad 8-1-2 is formed on the rubber ring on one side of the notch (the rubber ring on one side of the notch can be used directly as the retaining pad 8-1-2, or an additional retaining pad 8-1-2 can be set). A limiting post 8-1-3 can be set on the other side of the notch.

[0408] During installation, bolts DAA are passed sequentially from back to front through the mounting through holes 36-3-1 of the mounting flange 36-3 of the mounting housing 36 and the edge mounting holes AB-A of the silicone part AB, and then fixed to the back plate.

[0409] Method 2 (e.g.) Figure 4-9 As shown):

[0410] A circular hole is made on the back plate 8, which serves as a mating through hole 8-1. A notch 8-1-1 is made on the inner wall of the mating through hole 8-1. The pre-made silicone part AB is then installed aligning with this circular hole. The silicone part AB has a variable-diameter through hole, meaning the inner diameter of the front through hole is smaller than the inner diameter of the rear through hole, causing the rear inner wall of the silicone part AB to expand outwards, forming a stepped shoulder AB-1. The front through hole (the smaller inner diameter part) of the variable-diameter through hole is a secondary mating hole 08-1 corresponding to the mating through hole 8-1 (the diameter of the secondary mating hole 08-1 can be the same as or slightly larger than the diameter of the mating through hole 8-1). The space formed by the rear through hole (the larger inner diameter part) of the variable-diameter through hole is the space DA for accommodating the rotation of the fixing pin 35-1. At this point, the front through hole of the variable-diameter through hole, i.e., the secondary mating hole 08-1, is essentially formed by the surrounding rubber ring. A secondary notch 08-1-1 is provided on the inner wall of the secondary mating hole 08-1. During installation, the secondary notch 08-1-1 corresponds to the notch 8-1-1. A retaining gasket 8-1-2 is formed on the rubber ring on one side of the secondary notch (the rubber ring on one side of the secondary notch can be used directly as the retaining gasket 8-1-2, or a separate retaining gasket 8-1-2 can be used). A limiting post 8-1-3 can be provided on the other side of the secondary notch.

[0411] During installation, bolts DAA are passed sequentially from back to front through the mounting through holes 36-3-1 of the mounting flange 36-3 of the mounting housing 36 and the edge mounting holes AB-A of the silicone part AB, and then fixed to the back plate.

[0412] Method 3 (e.g.) Figure 4-10 and Figure 4-11 As shown):

[0413] A circular hole is drilled on the back plate 8, serving directly as a mating through hole 8-1. A notch 8-1-1 is drilled on the inner wall of the mating through hole 8-1. The pre-fabricated silicone part AB is then installed aligning with this circular hole. The silicone part AB has a secondary mating hole 08-1, which corresponds to the structure of the mating through hole 8-1 (the diameter of the secondary mating hole 08-1 can be the same as or slightly larger than the diameter of the mating through hole 8-1). In this case, the secondary mating hole 08-1 is essentially formed by a rubber ring. A secondary notch 08-1-1 is provided on the inner wall of this secondary mating hole 08-1. During installation, the secondary notch 08-1-1 corresponds to the notch 8-1-1, and a retaining gasket 8-1-2 is formed on the rubber ring on one side of the secondary notch. A limiting post 8-1-3 can be set on the other side of the secondary notch. In this method, the mounting flange 36-3 faces forward (e.g., Figure 4-10 (From the center to the right) Protruding a distance forms a raised ring L, so that the raised ring L forms a space DA to accommodate the rotation of the fixed pin 35-1.

[0414] During installation, bolts DAA are passed sequentially from back to front through the mounting through holes 36-3-1 of the mounting flange 36-3 of the mounting housing 36 and the edge mounting holes AB-A of the silicone part AB, and then fixed to the back plate.

[0415] Method 4 (e.g.) Figures 4-12 to 4-14 As shown):

[0416] A round hole is made on the back plate 8, which serves as a mating through hole 8-1. A notch 8-1-1 is made on the inner wall of the mating through hole 8-1, and a retaining gasket 8-1-2 is installed on one side of the notch on the back of the back plate. A limiting post 8-1-3 can be set on the other side of the notch. In this method, the mounting flange 36-3 protrudes forward by a distance to form a raised ring L, so that the raised ring L forms a space DA to accommodate the rotation of the fixing pin 35-1.

[0417] During installation, bolts DAA are passed sequentially from back to front through the mounting through holes 36-3-1 of the mounting flange 36-3 of the mounting housing 36 and the edge mounting holes AB-A of the silicone part AB, and then fixed to the back plate.

[0418] In this method, the fixing method of the pad 8-1-2 and the limiting post 8-1-3 to the back plate 8 can be as follows: Figure 4-13 As shown in the figure, the front of the back plate 8, i.e., the right side of the figure, faces the delivery and unloading compartment 2, and the left side is the back. The pad 8-1-2 and the limiting post 8-1-3 are installed on the back of the back plate 8. As shown in the figure, the installation method of the pad 8-1-2 and the limiting post 8-1-3 is the same (of course, different installation methods can also be used). The pad 8-1-2 and the limiting post 8-1-3 have a variable diameter through hole. Starting from the rear end (i.e., the left end shown in the figure), one end of the variable diameter through hole is a large diameter hole 0B-1, which is used to accommodate the nut 0B-3-2. From the front end of the large diameter hole 0B-1 (i.e., the right end of the figure) to the front end of the entire variable diameter hole (i.e., the right end of the figure), there is a small diameter hole 0B-2. A shoulder is formed between the large diameter hole 0B-1 and the small diameter hole 0B-2. The front end of the variable diameter hole on the back plate 8 has a through hole for the mounting bolt 0B-3 to pass through.

[0419] During installation, the externally threaded mounting bolt 0B-3 extends into the reducer hole from the rear end (e.g., Figure 4-13(As shown from left to right), and after passing through the small diameter hole 0B-2 and the back plate, it extends out of the back plate 8. Then, the nut 0B-3-1 is used to cooperate with the mounting bolt 0B-3 to fix the washer 8-1-2 and the limiting post 8-1-3. In this method, the outer surface of the nut 0B-3-2 can be provided with a cross or slotted groove similar to that on a self-tapping screw, which is convenient to operate with a Phillips screwdriver or a flathead screwdriver. For example, after the mounting bolt 0B-3 is placed into the reducing hole, the screwdriver is inserted into the large diameter hole 0B-1, and the screwdriver tip is inserted into the cross or slotted groove of the nut 0B-3-2 to hold the mounting bolt 0B-3 in place, preventing the mounting bolt 0B-3 from rotating. The nut 0B-3-1 can then be tightened on the other side. Alternatively, the large diameter hole 0B-1 can be set to be square, and the nut 0B-3-2 can also be set to be square so that it can be just placed into the square large diameter hole 0B-1 (the mounting bolt 0B-3 is still a conventional cylindrical shape). In this case, When tightening nut 0B-3-1, nut 0B-3-2 will act as an anti-rotation device. Of course, the installation method here is not limited to the above method. Any other feasible method can be used. For example, adhesive bonding or a flange-like mounting plate can be set on the gasket 8-1-2 and the limiting post 8-1-3, and then the gasket 8-1-2 and the limiting post 8-1-3 can be installed by fixing the mounting plate to the back plate 8 with bolts, etc., etc., which will not be elaborated here.

[0420] The mounting hole (35) is generally a circular tube structure.

[0421] like Figure 4-1 Figure 6 shows the mounting hole fixed installation method, in which the mounting hole is directly fixed to the back plate (different from the detachable type). Of course, other existing installation methods can also be used.

[0422] Embodiment 2 of the magnetic flexible connector 12: The magnetic flexible connector 12 includes a magnetic port 12-2 with a through hole. The through hole of the magnetic port 12-2 is connected to the exhaust pipe 4. The magnetic port 12-2 is a structure that can be attracted to the magnetic piece 12-1-2 on the lunch box placed in the delivery and distribution compartment 2 when in use. The magnetic clasp 12-1-2 is connected to the flexible corrugated tube 12-1, and the flexible corrugated tube 12-1 is connected to the exhaust port of the exhaust channel on the lunch box. In other words, a magnetic clasp 12-1-2 that mates with the magnetic clasp 12-2 is provided on the lunch box. This magnetic clasp 12-1-2 is connected to the flexible corrugated tube 12-1 and corresponds to the exhaust port of the exhaust channel on the lunch box. The connection method between the magnetic clasp 12-1-2 and the flexible corrugated tube 12-1 is as described above (i.e., the connection method between the magnetic clasp 12-1-2 and the flexible corrugated tube 12-1 in Embodiment 1). A gap is left between the flexible corrugated tube 12-1 and the exhaust port of the lunch box to allow the flexible corrugated tube 12-1 to move. During use, the magnetic suction port 12-2 and the magnetic suction piece 12-1-2 automatically align and engage to connect the exhaust pipe 4 with the exhaust channel of the food container contents. The magnetic suction piece 12-1-2 is a structure that can engage with the magnetic suction port 12-2, which means that: for example, the magnetic suction piece is a magnet and the magnetic suction port is an iron ring, or the magnetic suction piece is an iron ring and the magnetic suction port is a magnet; or the magnetic suction piece and the magnetic suction port are magnets with opposite magnetic pole directions.

[0423] In summary, the magnetic flexible connector 12 is configured as follows:

[0424] 1. When the magnetic flexible connector 12 is a magnetic port 12-2, it is directly installed at the exhaust port corresponding to the delivery and unloading compartment 2. The exhaust port mentioned here refers to the interface connecting the delivery and unloading compartment 2 and the exhaust pipe 4; for example, the exhaust port can be set on the back plate 8.

[0425] 2. When the magnetic flexible connector 12 includes a flexible corrugated tube 12-1 and a magnetic plate 12-1-2, the magnetic flexible connector 12 is located at the exhaust port of the exhaust pipe 4. The rear end of the flexible corrugated tube 12-1 is connected to the exhaust pipe 4. A gap C is left between the flexible corrugated tube 12-1 and the side wall of the exhaust port for the flexible corrugated tube 12-1 to move (as shown in Figure 6). The magnetic port 12-2, which is matched with the magnetic plate 12-1-2, is set on the lunch box that can be placed in the delivery and distribution compartment 2 during use. That is to say, the magnetic port 12-2 is set at the outlet of the exhaust channel of the lunch box. Figure 17-2 As shown, the connection between the lunch box exhaust channel 17 and the exhaust pipe 4 is achieved by the magnetic attraction of the magnetic plate 12-1-2 and the magnetic suction port 12-2.

[0426] In summary, the aforementioned magnetic suction port 12-2 and magnetic suction plate 12-1-2 cooperate as follows: When the lunchbox is placed in the corresponding position, the magnetic suction port 12-2 and magnetic suction plate 12-1-2 gradually approach each other. When they are within the range of attraction, if the magnetic suction port 12-2 is slightly off from the mounting hole 35 on the back plate, the flexible corrugated tube swings to actively find the position of the magnetic suction port 12-2 until the magnetic suction port 12-2 and magnetic suction plate 12-1-2 are attracted together, thus completing the connection of the exhaust pipe.

[0427] The module heat source 3 is installed on the base plate 7 inside the delivery and loading compartment 2. A slide groove 7-1 is provided on the base plate to the side of the module heat source 3. Further, a loading position motor 14 can be installed inside the base plate 7 (optional, that is, it can be omitted). The output shaft of the loading position motor 14 is provided with a transmission wheel 14-1. The transmission wheel 14-1 extends into the slide groove 7-1. The transmission wheel 14-1 can be partially inserted into the slide groove or entirely located in the slide groove. The transmission wheel can extend into the slide groove from the side of the slide groove 7-1 (at this time, the axis of the transmission wheel 14-1 is perpendicular to the base plate 7). A part of the transmission wheel 14-1 (the size of this part can be adjusted as needed) extends into the slide groove 7-1 from the side wall of the slide groove 7-1. The transmission wheel 14-1 is designed to cooperate with the transmission bar at the bottom of the lunch box placed in the delivery and loading compartment 2 to drive the lunch box to move (enter or exit the delivery and loading compartment 2). The pallet motor 14 is controlled by a central control module.

[0428] The transmission wheel 14-1 is a gear (that can mesh with the rack at the bottom of the lunch box) or a friction wheel (that is, a wheel with abrasive particles, rubber particles or other materials or structures that can increase friction, or a ready-made friction wheel can be purchased directly).

[0429] Furthermore, the workstation also includes a lunchbox, which includes an outer casing 15 and an inner casing 16. The inner casing 16 can be disposed inside the outer casing 15. The bottom of the outer casing 15 is provided with an opening, and the bottom of the inner casing 16, as the heated area D, is exposed from the opening at the bottom of the outer casing 15.

[0430] The inner box 16 mainly includes an inner box body 16-1 for storing food during use and a removable sealing film 16-3 that can temporarily seal the top opening of the inner box body 16-1 during use (for example, aluminum foil sealing film with edge pressing). The sealing film 16-3 is provided with vent holes.

[0431] The outer casing 15 mainly includes an outer casing 15-1 and an upper cover 15-2 that is placed on the outer casing 15-1 during use. The upper cover 15-2 is provided with a food container vent 17. The inlet end of the food container vent 17 is provided with a spherical cavity 17-1. The bottom of the elastic spherical cavity 17-1 is provided with a cavity vent 17-2 that corresponds to the vent hole 16-3-1 on the sealing film 16-3 during use. The food container vent 17 also includes a one-way valve to prevent gas from flowing back from the cavity vent (an existing one-way valve or a one-way valve method described later can be used).

[0432] When in use, the elastic spherical cavity 17-1 presses down on the sealing film 16-3 so that the vent of the cavity aligns with the vent hole on the sealing film 16-3. Simultaneously, other parts of the spherical cavity 17-1 press against the area around the vent hole, ensuring that air only enters the food container's venting channel 17 through the vent hole and the elastic spherical cavity 17-1, preventing leakage. It should be noted that during use, only the elastic spherical cavity 17-1 needs to contact the sealing film 16-3; other parts of the top cover 15-2 do not need to contact the sealing film 16-3. In the configuration of the pressure ring 15-2-5, it is used to press against the edge of the inner container. If the sealing film extends to the edge of the inner container, then the pressure ring 15-2-5 presses against the edge of the sealing film, primarily serving a positioning function. Even so, the edge of the sealing film is generally not directly heated. Additionally, the top cover 15-2... An internal cavity is provided, and the food container exhaust duct 17 can be located in the cavity. Then, the elastic spherical bladder 17-1 extends downward out of the cavity.

[0433] At this point, the rest of the food container vent 17 and most of the top cover 15-2 generally do not need to come into contact with the sealing film. The reason for saying "most of" is because... Figure 1 and Figure 5 As shown, this method uses a pressure ring 15-2-5.

[0434] The outlet end of the lunchbox vent 17 can be connected to a magnetic flexible connector 12; if the back plate 8 has a magnetic piece 12-1-2 connected to the flexible corrugated tube 12-1, then the outlet end of the lunchbox vent 17 is connected to a magnetic connector 12-2 (this magnetic connector 12-2 can be fixed; such as...). Figure 17-10 As shown), when in use, the magnetic suction port 12-2 on the lunch box automatically connects and engages with the magnetic suction piece 12-1-2 (automatic connection is achieved through the up, down, left, right and back movements of the flexible corrugated tube 12-1), thus completing the connection between the lunch box exhaust channel 17 and the exhaust channel 4.

[0435] If the back panel 8 has a fixed magnetic opening 12-2, then the outlet end of the lunchbox exhaust duct 17 is connected to a magnetic piece 12-1-2 that is connected to the flexible corrugated tube 12-1, such as... Figure 6-2 As shown, if a shell 17-17 is provided outside the lunch box exhaust duct 17 (this is the shell of the cavity provided inside the aforementioned top cover 15-2), then a gap C is also left between the magnetic piece 12-1-2 and the shell 17-17 for the flexible corrugated tube 12-1 to move. When in use, the magnetic piece 12-1-2 on the lunch box and the magnetic port 12-2 on the back plate 8 automatically connect and engage (automatic connection is achieved through the up, down, left, right and back movements of the flexible corrugated tube 12-1), thus completing the connection between the lunch box exhaust duct 17 and the exhaust duct 4.

[0436] If the back panel 8 has a magnetic suction plate 12-1-2 connected to the flexible corrugated tube 12-1, then the outlet end of the lunchbox exhaust duct 17 can also be connected to a magnetic suction plate 12-1-2 connected to the flexible corrugated tube 12-1, such as... Figure 6-2 As shown, if a shell 17-17 is provided outside the lunch box exhaust duct 17, then a gap C is also left between the magnetic piece 12-1-2 and the shell 17-17 for the flexible corrugated tube 12-1 to move. When in use, the magnetic piece 12-1-2 on the lunch box and the magnetic piece 12-1-2 on the back plate 8 automatically connect and engage (automatic connection is achieved by the up, down, left, right and back movements of the two flexible corrugated tubes 12-1), thus completing the connection between the lunch box exhaust duct 17 and the exhaust duct 4.

[0437] A one-way valve is provided at the vent of the bladder cavity to prevent gas from flowing back from the vent. The one-way valve is a swing plate 17-3 located at the vent of the bladder cavity, and a part of the swing plate 17-3 is connected to the edge of the vent of the bladder cavity. Figure 17-5 DB in the diagram refers to the connecting part; when using this oscillating piece 17-3, it covers the vent hole 16-3-1 of the sealing film 16-3. Its diameter is larger than the vent hole. When venting, it is pushed open by the gas discharged from the inner box below, such as... Figure 17-3A The arrow indicates the exhaust direction; when there is reverse flow of external gas, the oscillating plate 17-3 is pushed up from above by the reverse gas and covers the exhaust port 16-3-1, as shown by the arrow in Figure 17-4, thus preventing backflow.

[0438] The bottom of the top cover 15-2 is provided with a pressure ring 15-2-5 that can be pressed against the edge of the sealing film 16-3 during use. (The top cover 15-2 and the outer box body 15-1 are temporarily connected by a temporary buckle during use. This temporary buckle is similar to the buckles in existing lunch boxes and belongs to prior art. For example, such as...) Figures 30-1 to 30-4As shown, the buckle includes a buckle flap 15-2-6 and a slot 15-1-6 (slot opening downwards). The inner side of the buckle flap 15-2-6 is provided with a hook 15-2-6-1 that can engage the slot during use. The upper end of the buckle flap 15-2-6 is connected to the upper cover 15-2, and the slot 15-1-6 is connected to the side wall of the outer casing 15-1. The buckle flap 15-2-6 can be flipped up and down. Figure 30-3 As shown in the diagram, there are two curved arrows. The left arrow indicates the direction in which the latch flap 15-2-6 flips upward, and the right arrow indicates the direction in which it flips downward. Flipping the latch flap 15-2-6 upward separates the hook 15-2-6-1 from the slot 15-1-6, thus temporarily opening the latch. Flipping the latch flap 15-2-6 downward locks the hook 15-2-6-1 into the slot 15-1-6. This is existing technology and can be used directly. Of course, any other existing form of lunchbox latch can also be used, such as... Figure 30-5 and Figure 30-6 The buckle is in the form of a buckle flap 15-2-6 and a latch 15-1-7. The buckle flap 15-2-6 has a latching hole 15-2-6-2 that can be engaged with the latching tongue during use. The upper end of the buckle flap 15-2-6 is connected to the upper cover 15-2, and the latching tongue is connected to the side wall of the outer casing 15-1. The buckle flap 15-2-6 can be flipped up and down. Figure 30-6 As shown in the diagram, there are two curved arrows. The left arrow indicates the direction in which the latch flap 15-2-6 flips upward, and the right arrow indicates the direction in which the latch flap 15-2-6 flips downward. Flipping the latch flap 15-2-6 upward separates it from the latch tongue 15-1-7, thus opening the temporary latch. Flipping the latch flap 15-2-6 downward causes the latch hole 15-2-6-2 to engage with the latch tongue 15-1-7, thus securing the latch flap 15-2-6.

[0439] The above Figure 30-1 The card slot 15-1-6 is designed to surround the side wall of the outer casing 15-1, meaning the card slot 15-1-6 is arranged around the side wall of the outer casing 15-1. Figure 30-2 In this case, the card slot 15-1-6 is not set around the side wall of the outer box 15-1. The card slot 15-1-6 is only set at the position corresponding to the buckle flip plate 15-2-6. This is also existing technology and will not be elaborated here.

[0440] Additionally, one or more breathing holes 16-3-2 can be provided around the vent 16-3-1 (e.g., Figures 17-4C to 17-4eAs shown), the breathing hole 16-3-2 is a structure that can be pressed against the part around the vent 17-2 of the elastic spherical cavity 17-1 during use, and can separate from the elastic spherical cavity 17-1 when breathing is required (breathing means when the inner box tends to collapse). (This means that during normal ventilation, such as...) Figure 17-4d As shown, because the sealing membrane 16-3 is pushed upwards, the portion around the vent 17-2 of the spherical cavity 17-1 presses against the breathing hole 16-3-2. When the inner box 16-1 tends to collapse, the sealing membrane 16-3 is drawn downwards, causing the elastic spherical cavity 17-1 to separate from the breathing hole 16-3-2, thus balancing the air pressure and preventing the inner box from collapsing. Figure 17-4e During this process, the portion around the vent 17-2 of the elastic spherical bladder 17-1 always presses against the vent 16-3-1. If it is in the form of a swing plate 17-3, the swing plate 17-3 also always covers the vent 16-3-1. That is to say, the elastic spherical bladder 17-1 has an adaptive sealing effect.

[0441] In addition, a perforated partition 16-1-1 can be provided inside the inner box 16-1, which divides the inner box 16-1 into an upper cavity AA and a lower cavity BB.

[0442] The inner box 16-1 is either a one-piece aluminum foil box or a spliced ​​box;

[0443] The modular box includes an inner box wall 16-1-2 and an inner box heating bottom 16-1-3. An opening 16-1-2-5 is formed at the bottom of the inner box wall 16-1-2, and the inner box heating bottom 16-1-3 is installed at the opening.

[0444] One of the options is that the inner box wall 16-1-2 can be made of non-metallic material, and the inner box heating base 16-1-3 can be aluminum foil or aluminum composite.

[0445] When the inner box heating bottom 16-1-3 is made of aluminum foil, its connection with the inner box wall 16-1-2 can be one of the following two methods:

[0446] The first form: (e.g.) Figure 13—As shown in Figure 16, the bottom opening of the inner box wall 16-1-2 is provided with an opening edge 16-1-2-1 extending downwards around the bottom. Multiple elastic clips 21 are provided around the outer periphery of the opening edge 16-1-2-1. A gap DD is formed between the opening edge 16-1-2-1 and the elastic clips 21 to accommodate the outer edge of the inner box heating bottom 16-1-3. A pressure ring 22 presses the outer edge of the inner box heating bottom 16-1-3 into this gap, and the elastic clips 21 secure the pressure ring 22. (In use, the outer edge of the box heating bottom 16-1-3 is inserted into the gap DD. The outer edge of the box heating bottom 16-1-3 can be like...) Figure 14 With that outward-folding structure, the pressure ring is placed into the gap DD to press against the outer edge of the heating bottom 16-1-3 of the box. When it is pressed in, because the elastic clip 21 is an elastic element, it will be pushed open when the pressure ring is initially pressed in. After the pressure ring is pressed into the gap DD, the elastic clip 21 resets and locks the pressure ring in place.

[0447] Additionally, the top of the elastic card 21 can be provided with a protrusion EE that extends towards the opening in the direction of 16-1-2-1, so that the gap DD forms a structure with a small opening and a large interior. Furthermore, the protrusion EE can be arc-shaped or sloping (the so-called sloping shape is like...). Figure 16 As shown, a ramp FF is formed at the bottom of the protrusion EE to facilitate the pressing of the pressure ring.

[0448] The second form: The bottom opening of the inner box wall 16-1-2 has an opening edge 16-1-2-1 extending downwards around its perimeter. Multiple hot melt adhesive studs 23 are arranged around the outer perimeter of the opening edge 16-1-2-1. After the inner box heating bottom 16-1-3 covers the opening edge 6-1-2-1, the outer edge HH of the inner box heating bottom 16-1-3 is pressed tightly against the bottom of the inner box wall 16-1-2 by the hot melt adhesive studs 23. Furthermore, multiple hot melt adhesive studs 23 are arranged along the outer edge HH of the inner box heating bottom 16-1-3, with each subsequent hot melt adhesive stud 23 pressing against the previous one (e.g., ...). Figure 18 , 19 As shown, the specific operation method is to flatten the glue nails using a hot melt method, and then stack them one on top of the other along the outer edge (HH).

[0449] (like Figure 11 , 12 (As shown) When the inner box heating bottom 16-1-3 is an aluminum composite, its connection with the inner box wall 16-1-2 is as follows: the aluminum composite is divided into three layers. The first layer is an aluminum foil layer 16-1-3-1, the second layer is an intermediate layer 16-1-3-2 of the same material as the inner box wall 16-1-2, and the third layer is an aluminum foil layer 16-1-3-3 of the same material as the first layer. The intermediate layer 16-1-3-2 is sandwiched between the first layer and the third layer.

[0450] The first layer 16-1-3-1 is recessed around the second layer to form a connecting groove CC that exposes the second layer. The connecting groove CC is connected to the bottom opening 16-1-2-2 of the inner box wall 16-1-2 around the perimeter (it can be glued or heat-fused, since they are made of the same material, the connection method is easy to handle, and the existing connection method can be used). At this time, the first layer 16-1-3-1 completely covers the bottom opening 16-1-2-2 of the inner box wall 16-1-2.

[0451] In addition, a food container 15-2-1 for holding food is provided above the upper cover 15-2. The food container 15-2-1 can be configured in one of the following ways: First, the food container 15-2-1 is directly positioned above the upper cover 15-2 and integrated with it, with the upper end of the food container 15-2-1 being open. During packaging, the opening can be sealed with film; when consuming, the film can be removed. Alternatively, an openable upper cover can be provided at the opening, which can be opened when consuming. Second, the food container 15-2-1 is positioned above the upper cover 15-2 during use; that is, the food container 15-2-1 and the upper cover 15-2 are separate components. The removable type means that the food container 15-2-1 is placed on top of the cover 15-2 during use and temporarily connected to the cover 15-2 using any known snap-fit ​​method. Then, when in use, the food container 15-2-1 and the cover 15-2 can be removed together. At this point, the upper end of the food container 15-2-1 is open. During packaging, the opening can be sealed with film; when eating, the film can be torn off. Alternatively, an openable cover can be provided at the opening; when eating, simply open the cover. Alternatively, in this method, the snap-fit ​​between the food container 15-2-1 and the cover 15-2 can be opened during use to separate the food container 15-2-1. In this case, during packaging, the opening of the food container 15-2-1 can face upwards, and film can be sealed at the opening. To consume, simply tear off the sealing film, or use an openable lid at the opening; otherwise, simply open the lid to consume. Alternatively, during packaging, the opening of the food compartment 15-2-1 can be positioned downwards, such as... Figure 8 , 17-2As shown, during packaging, the opening of the food container 15-2-1 can be sealed with film, and then the lid can be placed upside down. When consuming, simply remove the food container 15-2-1, flip it over, and then tear off the film. Alternatively, during packaging, the opening of the food container 15-2-1 can be left unsealed. The lid 15-2 can be placed directly over the opening of the food container 15-2-1, where the lid 15-2 acts as a cover or seal for the opening of the food container 15-2-1. The food container 15-2-1 and the lid 15-2 can then be connected with a temporary snap fastener. After that, they can be inverted together and placed over the outer box 15-1 to complete the packaging. When consuming, remove the food container 15-2-1 and the lid 15-2 together, flip it over so that the opening of the food container 15-2-1 is facing upwards, then open the snap fastener and remove the lid 15-2.

[0452] Furthermore, the bottom of the outer casing 15 may be provided with a slide rail 15-1-5 (which can be inserted into the slide groove 7-1 during use and can move along the slide groove 7-1).

[0453] In addition, the bottom of the outer casing 15 is also equipped with a rack 15-1-1 or a friction strip (when the transmission wheel 14-1 is a gear, the bottom of the outer casing 15 is equipped with a rack 15-1-1 that can mesh with the gear, and the rack 15-1-1 can drive the lunch box to move under the meshing of the transmission wheel 14-1; when the transmission wheel 14-1 is a friction wheel, the bottom of the outer casing 15 is equipped with a friction strip, and when in use, the friction wheel contacts the friction strip, and the entire lunch box is driven to move by friction). That is to say, the bottom of the outer casing 15 can be equipped with only a slide rail, or only a rack 15-1-1 or a friction strip, or both a slide rail and a rack 15-1-1 or a friction strip (in this form, the rack 15-1-1 or the friction strip is generally located in front of the slide rail).

[0454] When a rack 15-1-1 or friction strip is provided, such as Figure 9-6 As shown, the bottom of the outer casing 15 is provided with a bottom sliding groove 15-1-2. The upper end of the rack 15-1-1 or friction strip extends into the bottom sliding groove 15-1-2, and the rack 15-1-1 or friction strip can move along the bottom sliding groove 15-1-2 (the direction of movement is along the length of the rack 15-1-1 or friction strip). Figure 9-6 (in the left and right directions), the rack 15-1-1 or friction strip extends into the bottom plate groove 7-1 when in use.

[0455] The connection between the rack 15-1-1 or friction strip and the bottom groove 15-1-2 can be detachable, as detailed below:

[0456] The top of the rack 15-1-1 or friction bar has two rows (e.g.) Figure 9-7 As shown in the left and right rows, each row is provided with one or more elastic toothed plates. The elastic toothed plates are divided into tooth body 15-1-A and tooth top 15-1-B located on top of tooth body 15-1-A. Tooth top 15-1-B is a slope that gradually slopes outward from top to bottom. The outermost end of the slope and tooth body 15-1-A form a bottom clamp XD for locking the upper edge of the bottom slide groove 15-1-2 of the box when in use.

[0457] (that is, like) Figure 9-7 As shown, the slope slopes outwards from top to bottom (meaning the left slope gradually slopes from top to bottom and then to the left, while the right slope gradually slopes from top to bottom and then to the right). During installation, if... Figure 9-9 As shown, align the elastic toothed piece with the bottom groove 15-1-2 and insert it. The inclined surface of the tooth tip is gradually pressed inward by the bottom groove 15-1-2, causing the elastic toothed piece to gradually deform and extend into the bottom groove 15-1-2. After the inclined surface of the tooth tip passes through the bottom groove 15-1-2, the elastic toothed piece returns to its original position, causing the bottom edge XD of the inclined surface of the tooth tip 15-1-B to engage with the upper edge of the bottom groove 15-1-2. Figure 9-7 As shown, at this time, the elastic toothed piece 15-1-A can move within the bottom slide groove 15-1-2 of the box, and because the bottom of the inclined surface of the toothed tip 15-1-B, the bottom catch XD, is stuck to the upper edge of the bottom slide groove 15-1-2 of the box, the elastic toothed piece will not fall off; when it is necessary to remove the toothed strip 15-1-1 or the friction strip, above the bottom slide groove 15-1-2 of the box, use your hand or a tool to clamp the toothed tips 15-1-B of the two rows of elastic toothed pieces, so that the bottom catch XD leaves the bottom slide groove 15-1-2 of the box, and then push out the toothed strip 15-1-1 or the friction strip.

[0458] Furthermore, a bottom cushioning component 15-1-3 (such as a cushioning strip or spring) can be provided within the bottom groove 15-1-2 of the box.

[0459] The bottom buffer 15-1-3 is set on one or both sides of the rack 15-1-1 or friction strip. The bottom buffer 15-1-3 is generally set in one of the following forms (taking the rack as an example):

[0460] Form 1: The bottom buffer 15-1-3 can move together with the rack 15-1-1. In this form, the bottom buffer 15-1-3 can be directly connected to the rack 15-1-1, or it can only contact the rack 15-1-1 when moving. For example, when the rack 15-1-1 moves forward, it will push the bottom buffer 15-1-3 to move a small distance together until it reaches its limit. Then the bottom buffer 15-1-3 stops moving and buffers the rack 15-1-1 through its own deformation. The same applies when the rack moves backward.

[0461] Form 2: The bottom buffer 15-1-3 is fixed, and there is a gap for movement between the rack 15-1-1 and the bottom buffer 15-1-3. That is to say, in this case, after the rack 15-1-1 moves a small distance, it contacts the bottom buffer 15-1-3, and the buffer is achieved through the bottom buffer 15-1-3; the bottom buffer 15-1-3 can be fixed in the bottom groove 15-1-2.

[0462] Form 3: The bottom buffer 15-1-3 is set on both sides of the rack 15-1-1. One side of the bottom buffer 15-1-3 is fixed, while the other side of the bottom buffer 15-1-3 can move with the rack 15-1-1. The bottom buffer 15-1-3 that can move with the rack 15-1-1 is directly connected to the rack 15-1-1 or can touch the bottom buffer 15-1-3 and move together when the rack 15-1-1 moves.

[0463] Form 4: The bottom buffer 15-1-3 is set on both sides of the rack 15-1-1. The bottom buffer 15-1-3 on both sides is fixed and clamps the rack 15-1-1. In other words, in this case, the rack 15-1-1 and the bottom buffer 15-1-3 are in contact or connected. So when the transmission wheel 14-1 meshes with the rack 15-1-1, the deformation of the bottom buffer 15-1-3 achieves buffering of the rack 15-1-1.

[0464] When the rack 15-1-1 or friction strip moves, it can contact the bottom buffer 15-1-3 (this bottom buffer 15-1-3 is optional). The aforementioned bottom groove 15-1-2 is a small section, allowing the rack 15-1-1 or friction strip to move relatively a small distance (not allowing the rack 15-1-1 or friction strip to move continuously or a large distance). When the rack 15-1-1 or friction strip is engaged or pushed by friction, such as... Figure 9-6As shown, rack 15-1-1 or friction strip will move a small section to the left until it abuts against bottom buffer 15-1-3, where its movement is stopped. If bottom buffer 15-1-3 is not provided, rack 15-1-1 or friction strip will be stopped by the end of bottom slide groove 15-1-2. At this time, rack 15-1-1 or friction strip will start (directly or against bottom buffer 15-1-3) to move the lunchbox. The main function of bottom slide groove 15-1-2 is to prevent transmission wheel 14-1 from jamming with rack 15-1-1, because the compartment door is not very large. Taking a gear and rack as an example, if a gear meshing rack movement structure is used, during operation, when starting, the gear will have a relatively strong instantaneous force pushing the rack. If the rack is directly fixed, the gear and rack will jam. The function of the bottom slide groove 15-1-2 is to solve this problem, to remove the force of the gear pushing the rack, so that the transmission wheel 14-1 and the rack will not jam when starting.

[0465] In another configuration, the upper end of the rack 15-1-1 or friction strip is provided with a protrusion 15-1-1-1. The protrusion 15-1-1-1 extends into the bottom groove 15-1-2 and can move along the bottom groove 15-1-2. When the rack 15-1-1 or friction strip moves, the protrusion 15-1-1-1 contacts the cushioning strip 15-1-3. The protrusion can be in the following form: Figure 9-10 As shown in the figure, the protrusion has a T-shaped cross-section and is fitted onto the upper edge of the bottom slide groove 15-1-2, directly engaging with the bottom slide groove 15-1-2 for installation.

[0466] Additionally, it should be noted that the transmission bar at the bottom of the outer casing 15 is either a rack 15-1-1 that can mesh with the transmission wheel 14-1 or a friction bar that cooperates with the transmission wheel 14-1; the rack 15-1-1 is a structure that can drive the lunchbox to move under the meshing of the transmission wheel 14-1.

[0467] In the above cases, a slide rail 15-1-5 (also called a lunch box guide foot) that mates with the slide groove 7-1 can be set only at the bottom of the outer jacket 15, or a rack 15-1-1 (or friction strip) can be set only at the bottom of the outer jacket 15, or both the slide rail 15-1-5 and the rack 15-1-1 (or friction strip) can be set.

[0468] If both slide rail 15-1-5 and rack 15-1-1 (or friction bar) are provided, then the following options are preferred:

[0469] The first scenario: One side of the bottom of the outer jacket 15 is equipped with only a rack 15-1-1 (or a friction strip), while the other side is equipped with only a slide rail 15-1-5;

[0470] The second scenario: One side of the bottom of the outer jacket 15 is equipped with both a rack 15-1-1 (or friction strip) and a slide rail 15-1-5, and the other side of the bottom of the outer jacket 15 is also equipped with both a rack 15-1-1 (or friction strip) and a slide rail 15-1-5; In this scenario, the rack 15-1-1 (or friction strip) is positioned in front of the slide rail 15-1-5, and the slide rail 15-1-5 and the rack 15-1-1 or friction strip are preferably on the same extension line;

[0471] The third scenario: Figure 17-10 The bottom side of the outer jacket 15 is provided with both a rack 15-1-1 (or friction strip) and a slide rail 15-1-5, while the bottom side of the outer jacket 15 is provided with only a slide rail 15-1-5. In this case, the rack 15-1-1 (or friction strip) is located in front of the slide rail 15-1-5, and the slide rail 15-1-5 and the rack 15-1-1 or friction strip are preferably on the same extension line.

[0472] Of course, there are other possible scenarios.

[0473] Furthermore, on the back panel 8 of the corresponding delivery and fulfillment warehouse 2 (such as...) Figure 4-1 (as shown) or within the groove 7-1 (such as) Figure 27-3 (As shown) A limit switch 19 is provided to stop the loading position motor 14 when the outer casing 15 is touched. The limit switch 19 is installed within the chute 7-1 in such a manner as... Figure 27-3 and Figure 27-4 As shown, the limit switch at this time can be an existing product from Delixi, Chint, etc., and its appearance is as follows. Figure 27-4 As shown, the main body is placed inside the base plate 7, and the rollers extend into the slide groove. When the lunchbox is placed in, the slide rail 15-1-5 moves within the slide groove 7-1. After the lunchbox reaches the designated position, the slide rail 15-1-5 touches the limit switch. That is to say, in this case, taking the above "third case" as an example, as follows: Figure 17-10 One side of the bottom of the outer casing 15 is equipped with both a rack 15-1-1 (or friction strip) and a slide rail 15-1-5, while the other side of the bottom of the outer casing 15 is equipped with only a slide rail 15-1-5 (the limit switch 19 is located in the groove 7-1 corresponding to the slide rail 15-1-5 on the corresponding side). In this case, the rack 15-1-1 (or friction strip) is located in front of the slide rail 15-1-5. When the lunch box is placed in, the rack 15-1-1 (or friction strip) is engaged, which drives the slide rails 15-1-5 on both sides to move in the groove 7-1. After the lunch box reaches the designated position, only one side of the slide rail 15-1-5 is equipped, and the slide rail 15-1-5 touches the limit switch.

[0474] In addition, taking transmission wheel 14-1 as a gear as an example: Figure 7-1The diagram shows one form of the transmission wheel 14-1, in which the axis of the transmission wheel 14-1 is perpendicular to the base plate. In this case, the rack 15-1-1 is vertical and meshes with the transmission wheel 14-1; as shown... Figure 7-2 Another form of the transmission wheel 14-1 is in which the axial direction of the transmission wheel 14-1 is parallel to the base plate. In this case, the rack 15-1-1 is transverse or L-shaped. If it is L-shaped, the teeth of the transverse portion mesh with the transmission wheel 14-1. Figure 7-3 As shown, the axial direction of the transmission wheel 14-1 is parallel to the base plate. The transmission wheel 14-1 can be a bevel gear (also called a bevel gear). The rack 15-1-1 is either oblique or has a beveled bottom. If it is an oblique rack 15-1-1, it directly meshes with the transmission wheel 14-1. If it is a rack 15-1-1 with a beveled bottom, the teeth of the beveled bottom part of the rack mesh with the transmission wheel 14-1. Of course, any other form that can achieve this function can also be used.

[0475] Furthermore, preferably, in the form where a slide rail 15-1-5 is provided at the bottom of the outer casing 15, the slide rail 15-1-5 has a structure that extends downward, diagonally downward, or laterally. When the slide rail (15-1-5) has a structure that extends downward or diagonally downward, the lower part of the slide rail 15-1-5 can be an outwardly inclined structure (e.g., Figure 17-6 As shown in Figure 17-7 (15-B in Figure 17-7 is the inclined structure), the base plate 7 is also provided with a downward guide wheel 03. The downward guide wheel 03 is located in or extends into the slide groove 7-1 (that is to say, the downward guide wheel 03 can be entirely placed in the slide groove 7-1 or partially extended into the slide groove 7-1. For the partially extended form, see Figure 17-7. Of course, the form shown in the figure is only one form, and there can be other forms). When the slide rail (15-1-5) is a structure that extends laterally, the downward guide wheel (03) is a structure that can press down on the slide rail (15-1-5) when in use. When the slide rail (15-1-5) is a structure that extends downward and obliquely downward, the downward guide wheel (03) is a structure that can press down on the outwardly inclined part of the lower part of the slide rail when in use.

[0476] like Figures 17-7A to 17-7fAs shown, the downward guide wheel 03 extends into the slide groove 7-1 from the side. The downward guide wheel 03 is mounted on the vertical guide post 05 and can rotate (about the vertical guide post 05 as an axis) and move up and down along the vertical guide post 05 (axial direction). Springs are provided above, below, or both above and below the downward guide wheel 03 (meaning that a spring can be provided above the downward guide wheel 03; when a spring is provided above the downward guide wheel 03, it is a downward spring). 04. When a spring is installed below the downward guide wheel 03, the spring is a pull-down spring. When springs are installed at both the top and bottom, the upper one is a downward spring and the lower one is a pull-down spring. When the slide rail 15-1-5 of the lunch box extends into the slide groove 7-1, the downward guide wheel 03 contacts the outwardly inclined part 15-B of the lower part of the slide rail 15-1-5. At this time, the downward guide wheel 03 rotates to complete the guidance, and the outwardly inclined part 15-B will exert an upward force on the downward guide wheel (03). The compression spring has a tendency to be compressed. The downward force of the compression spring 04 maintains a downward force on the outwardly inclined part 15-B of the slide rail 15-1-5, so that the bottom of the inner box is more tightly connected with the heating module. If it is a pull-down spring, it will have a tendency to be stretched during use. At this time, the pull-down spring will have a force to pull down the guide wheel 03. Under the downward action of the pull-down spring, the guide wheel 03 can always maintain a downward force on the outwardly inclined part 15-B of the slide rail 15-1-5, so that the overall combination of the food box and the heating module is tighter.

[0477] The downward guide wheel 03 can be directly fitted onto the vertical guide post 05. A spring 04 is installed above the downward guide wheel 03. The upper end of the downward spring 04 is connected to or touches the upper top plate KQ-1 of the cavity KQ of the base plate 7, or the upper end of the downward spring 04 is connected to or touches the upper part of the vertical guide post 05 (in the form of touching the upper part of the vertical guide post 05, a flange or a horizontal post or similar structure is set on the upper part of the vertical guide post 05, and then the upper end of the downward spring 04 touches the flange or the horizontal post). The lower end of the downward spring 04 touches the downward guide wheel 03. At this time, the bottom of the hole KK for the downward guide wheel 03 to extend into the slide groove 7-1 is higher than the bottom of the slide groove 7-1 by a certain amount G. Figure 17-7A As shown, alternatively, a guide wheel limiting structure can be installed on the vertical guide post 05 below the guide wheel 03 to prevent the guide wheel 03 from falling to the bottom. When there is no food container, the guide wheel 03 is pressed against the bottom of the hole KK or against the guide wheel limiting structure by the action of the spring 04; or as shown... Figure 44As shown, the bottom surface KQ-2 of the cavity KQ is flush with the bottom of the hole KK. When there is no food container, the pressure guide wheel 03 is pressed against the bottom surface KQ-2 of the cavity KQ by the pressure spring 04. In this case, a circular piece can also be set above the pressure guide wheel 03. The pressure guide wheel 03 and the circular piece can rotate relative to each other. Then the lower end of the pressure spring 04 touches or connects to the circular piece.

[0478] Additionally, the downward guide wheel 03 can be mounted on the vertical guide post 05 via a guide sleeve. The guide sleeve can be a sleeve that can move up and down relative to the vertical guide post 05. The downward guide wheel 03 is then fitted onto this sleeve. The upper and lower ends of the sleeve are equipped with plugs (which can be horizontal posts perpendicular to the outer wall of the sleeve, or a structure similar to a flange) to prevent the downward guide wheel 03 from detaching from the sleeve. In this case, the downward guide wheel 03 can rotate around the sleeve as an axis. Alternatively, a bearing can be installed between the downward guide wheel 03 and the sleeve. Furthermore, the downward guide wheel 03... Alternatively, a bearing can be directly mounted on the vertical guide post 05. In this case, the bearing can move up and down relative to the vertical guide post 05, and the bearing directly acts as a guide sleeve. The downward guide wheel 03 can move up and down along the vertical guide post 05 with the guide sleeve or bearing, and the downward guide wheel 03 can rotate around the vertical guide post 05 as an axis. Springs are set above, below, or both above and below the downward guide wheel 03. This means that a spring can be set above the downward guide wheel 03. When a spring is set above the downward guide wheel 03, the spring is a downward spring 04. The upper end of the downward spring 04 is connected to or contacts the downward guide post (in the form of contacting the upper part of the vertical guide post 05, a flange, a horizontal column, or a similar structure is set on the upper part of the vertical guide post 05, and then the downward pressure is applied). The upper end of spring 04 contacts the flange or the top of the horizontal column), or the upper end of the pressure spring 04 is connected to or contacts the upper top plate KQ-1 of the cavity of the base plate 7, as shown in Figure 17-7. At this time, the position for installing the pressure guide column is the cavity KQ of the hollow structure. The upper end of the pressure guide column is connected to the upper top plate of the cavity KQ, and the lower end is connected to the lower bottom plate of the cavity KQ. The lower end of the pressure spring 04 is connected to or contacts the guide sleeve (in the form where the lower end of the pressure spring 04 contacts the guide sleeve, the bottom of the hole KK in the groove 7-1 for the pressure guide wheel 03 to extend into the groove 7-1 is higher than the bottom of the groove 7-1 by a section G, as shown in Figure 17-7. Alternatively, a limiting structure can be set on the vertical guide column 05 below the pressure guide wheel 03 to prevent the pressure guide wheel 03 from falling to the bottom and failing).

[0479] In another scenario, when a spring is installed below the pressure guide wheel 03, the spring is a pull-down spring. The lower end of the pull-down spring is fixed to the bottom plate of the pressure guide post or the cavity of the bottom plate 7, and the upper end is connected to the guide sleeve. When springs are installed at both the top and bottom, the upper one is the pressure spring and the lower one is the pull-down spring.

[0480] The function of the downward guide wheel 03 is that when the slide rail 15-1-5 of the lunch box extends into the slide groove 7-1, the downward guide wheel 03 contacts the outwardly inclined lower part 15-B of the slide rail 15-1-5, and the downward guide wheel 03 rotates to complete the guidance. At this time, the downward action of the downward spring 04 or the pull spring can ensure the tightness of the overall fit between the lunch box and the heating module. That is, when the lunch box is in place, the downward guide wheel 03 is lifted away from the bottom surface KQ-2 of the original position, and the downward spring 04 is compressed to apply pressure to the inclined surface of the slide rail 15-1-5 through the downward guide wheel 03. The vertical component of this pressure helps the lunch box fit with the heat source 3 of the heating module, and the horizontal component guides the lunch box. Figure 17-7D SLW is the position where force is applied.

[0481] like Figure 17-7g This is another form of the downward-pressing guide wheel 03, in which the axis of the downward-pressing guide wheel 03 is parallel to the base plate (in the previously described form, the axis of the downward-pressing guide wheel 03 is perpendicular to the base plate, such as...). Figure 17-7A As shown in the figure, a horizontal plate 7-1-1 is provided at the upper end of the slide rail. The upper end of the vertical guide post 05 is connected to the horizontal plate 7-1-1. The downward guide wheel 03 is connected to the guide frame 03-1. The upper end of the guide frame 03-1 is fitted onto the vertical guide post 05 and can move up and down along the vertical guide post 05. The downward spring 04 is fitted onto the vertical guide post 05, and the upper end of the downward spring 04 is connected to the horizontal plate 7-1-1. The lower end of the downward spring 04 is connected to the guide frame 03-1. As shown in the figure, the downward guide wheel 03 presses against the slide rail 15-1-5 (if the slide rail 15-1-5 is horizontal, it directly presses against the slide rail 15-1-5; if the slide rail is diagonal, it also directly presses against the diagonal slide rail; if the slide rail 15-1-5 is...). Figure 17-7g The lower part shown has an outwardly inclined portion 15-B, in which the downward guide wheel 03 presses down on the outwardly inclined portion 15-B.

[0482] This form is just one of many possible forms; other similar forms are also possible.

[0483] In addition, when the slide rail 15-1-5 is a structure that extends laterally and downwards, the front end of the slide rail is provided with a ramp surface to facilitate the rotation of the pressure guide wheel 03 onto the slide rail 15-1-5; when the slide rail 15-1-5 is a structure that extends downwards and downwards and the lower part of the slide rail 15-1-5 is provided with an outwardly inclined structure 15-B, the front end of the outwardly inclined structure 15-B of the slide rail 15-1-5 (which can also be called a lunchbox guide leg) is provided with a front inclined surface OB to facilitate the rotation of the pressure guide wheel 03 onto the outwardly inclined structure 15-B (that is, an inclined surface is provided at the front end of the outwardly inclined structure 15-B of the slide rail 15-1-5 so that the pressure guide wheel 03 can smoothly roll onto the outwardly inclined structure 15-B through the inclined surface to complete the downward pressure of the outwardly inclined structure 15-B).

[0484] Furthermore, regarding the module heat source 3, the module heat source 3 is a structure that can adaptively fit with the heated area at the bottom of the inner box of the lunch box.

[0485] One type of adaptive fitting structure (spring-supported leg structure):

[0486] The bottom of the module heat source 3 is equipped with an adjustment spring 01 (the function of the adjustment spring 01 is to automatically adjust so that when the bottom of the inner box 16 is tilted, it can ensure that the bottom of the inner box 16 is in complete contact with the module heat source 3 as much as possible).

[0487] Furthermore, the adjusting spring 01 (preferably) consists of two or more springs.

[0488] The adjustment springs 01 (preferably) are four in number. The four adjustment springs 01 are evenly distributed at the bottom of the module heat source 3. (The term "evenly distributed" means that the four adjustment springs 01 are similar to the four legs of a table, supporting the module heat source 3. For example, if the module heat source 3 is square, the four adjustment springs 01 can be distributed at or near the four corners of the module heat source 3. If the module heat source 3 is round, the angle between adjacent lines connecting the points of contact between the four adjustment springs 01 and the module heat source 3 to the center of the module heat source (3) is equal, and preferably the lengths of each line are also equal. Of course, uneven distribution is also acceptable, as long as it does not affect the implementation of the adjustment function. In addition, the adjustment springs 01 can also be six, eight, etc., whichever is required.)

[0489] Furthermore, the adjusting spring 01 is fitted onto the guide post 02, the upper end of the guide post 02 extends into the bottom of the module heat source 3, and the module heat source 3 can move relative to the guide post 02 along the guide post. The top of the adjusting spring 01 is in contact with or connected to the bottom of the module heat source 3 (e.g., Figure 17-9As shown, the position for mounting the module heat source 3 on the base plate 7 is a base plate mounting groove 7-2. The adjusting spring 01 and the guide post 02 are located in the mounting groove 7-2. The bottom of the module heat source 3 is provided with a receiving groove 3-1. The top end of the guide post 02 extends into the receiving groove 3-1, and the bottom end of the guide post 02 is connected to the bottom of the mounting groove 7-2. The top end of the adjusting spring 01 touches or connects to the bottom of the module heat source (3), and the bottom end of the adjusting spring 01 connects or touches the bottom of the mounting groove 7-2. In this way, for example, with Figure 40 For example, when the bottom of the inner box 16-1 tilts, the module heat source 3 will also adjust adaptively to the bottom of the inner box 16-1 to better adapt to the tilted bottom of the inner box 16-1. And combined with... Figure 37-1 and 37-2 In this configuration, the bottom of the heat insulation mounting plate 39 is provided with a receiving groove 3-1, and the top end of the guide post 02 extends into the receiving groove 3-1. The top end of the adjusting spring 01 touches or connects to the bottom of the heat insulation mounting plate 39, and the bottom end of the adjusting spring 01 connects to or touches the bottom of the mounting groove 7-2. Alternatively, the bottom of the guide post 02 is connected to the mounting positioning seat 42, and then the bottom of the mounting positioning seat 42 is connected to the bottom of the mounting groove 7-2. Other feasible methods are also acceptable.

[0490] The second type of adaptive fitting structure (spherical mating structure):

[0491] like Figure 47 and Figure 48 As shown, the bottom of the module heat source 3 is a module spherical structure 3A. Below the module spherical structure 3A is a lower spherical surface 3B that can contact and cooperate with the module spherical structure 3A (both the module spherical structure 3A and the lower spherical surface 3B are partial spherical surfaces and their spherical surfaces are equal or compatible). The module spherical structure 3A can slide and cooperate with the lower spherical surface 3B (after installation and positioning, the module spherical structure 3A and the lower spherical surface 3B have two degrees of freedom in contact and cooperation, and the module heat source can slide and adjust according to the cooperation between the module spherical structure 3A and the lower spherical surface 3B, such as...). Figure 48 As shown, when the bottom of the inner box is slightly tilted, the module heat source 3 enters the adjustment swing state, at which time the module heat source 3 forms a swing angle difference (jdc).

[0492] The third type of adaptive fitting structure (spherical joint with spherical surface):

[0493] The bottom of the module heat source 3 is a module spherical structure 3A. Below the module spherical structure 3A is a lower spherical surface 3B that can contact and cooperate with the module spherical structure 3A (both the module spherical structure 3A and the lower spherical surface 3B are partial spherical surfaces and their spherical surfaces are equal or compatible). The module spherical structure 3A can slide and cooperate with the lower spherical surface 3B. After installation and positioning, the two degrees of freedom of the module spherical structure 3A and the lower spherical surface 3B are in contact and cooperate, and the module heat source can slide and adjust according to the cooperation between the module spherical structure 3A and the lower spherical surface 3B.

[0494] It also includes a ball-end screw 50, the upper end of which, ball head 50-1, is ball-jointed with the module heat source 3 (or forms a spherical bearing structure). The lower end of the ball-end screw 50 extends into the mounting hole 52. The ball-end screw 50 can swing and move up and down relative to the mounting hole 52 (that is, the ball-end screw 50 can move up and down, and the upper end, ball head 50-1, can swing back and forth and left and right; in other words, sufficient swing clearance must be left between the upper opening of the mounting hole 52 and the ball-end screw 50). A compression spring 51 or a tension spring is also provided in the mounting hole 52. If it is a compression spring, the compression spring 51 is fitted onto the part of the ball-end screw 50 that extends into the mounting hole 52. The upper end of the compression spring 51 contacts or connects to the top inner wall of the mounting hole 52, and the lower end of the compression spring 51 contacts or connects to the nut 50-2 at the lower part of the ball-end screw 50 (e.g., Figure 42 and Figure 44 As shown, when the bottom of the inner box tilts, the module heat source 3 enters an adjustment swing state. At this time, the module heat source 3 forms a swing angle difference jdc. The ball head screw 50 tilts, and the compression spring 51 is compressed. After the food box is removed, the module heat source 3 is reset by the reset of the compression spring 51. If a tension spring is used, it is located at the bottom of the ball head screw 50. The upper end of the tension spring is connected to the nut 50-2 at the bottom of the ball head screw 50, and the lower end of the tension spring is connected to the bottom of the mounting hole 52. (When the bottom of the inner box tilts, the module heat source 3 enters an adjustment swing state. At this time, the module heat source 3 forms a swing angle difference jdc. The ball head screw 50 tilts, and the tension spring is stretched. After the food box is removed, the module heat source 3 is reset by the reset of the tension spring.)

[0495] In this method, the upper ball joint 50-1 of the ball screw 50 and the ball joint of the module heat source 3 can also be divided into the following forms:

[0496] Form 1: such as Figures 39-42 As shown, the upper ball head 50-1 of the ball screw 50 passes through the spherical structure 3A of the module and is spherically hinged to the heating panel 37 of the module heat source 3. A clearance hole 39-A is provided on the spherical structure 3A for the upper ball head 50-1 to pass through, and a gap is provided between the ball screw 50 and the clearance hole 39-A to allow the ball screw 50 to swing. (As shown) Figures 39-42As shown, the heating module at this time may include a heating panel 37, heating components, and a heat-insulating mounting plate 39, etc. The heating panel 37 and the heat-insulating mounting plate 39 are installed together, and heat-insulating silicone 40 can be set between the heating panel 37 and the heat-insulating mounting plate 39. At this time, the base plate of the heat-insulating mounting plate 39 is a module spherical structure 3A, and then the ball head screw 50 passes through the clearance hole 39-A of the module spherical structure 3A and is ball-hinged with the heating panel 37; as shown Figure 42 As shown, when the bottom of the inner box is tilted, the module heat source 3 enters the adjustment swing state. At this time, the module heat source 3 forms a swing angle difference jdc. At this time, the ball head screw 50 tilts and the compression spring 51 is compressed (if it is the above-mentioned tension spring, the tension spring is stretched). After the lunch box is removed, the module heat source 3 is reset by the reset of the compression spring 51 (or tension spring).

[0497] Form Two:

[0498] The upper end ball joint 50-1 of the ball joint screw 50 is hinged to the spherical structure 3A of the module (as shown in Figure 43). Figure 44 As shown, the heating module at this time may include a heating panel 37, heating components, and a heat-insulating mounting plate 39, etc. The heating panel 37 and the heat-insulating mounting plate 39 are installed together. Heat-insulating silicone 40 can be provided between the heating panel 37 and the heat-insulating mounting plate 39. At this time, the base plate of the heat-insulating mounting plate 39 is a module spherical structure 3A, and then the ball head screw 50 is ball-hinged with the module spherical structure 3A, as shown. Figure 44 As shown, when the bottom of the inner box is tilted, the module heat source 3 enters the adjustment swing state. At this time, the module heat source 3 forms a swing angle difference jdc. At this time, the ball screw 50 tilts, and the tension spring is stretched (if it is a compression spring 51, the compression spring is compressed). After the lunch box is removed, the module heat source 3 is reset by the reset of the tension spring.

[0499] The fourth type of adaptive fitting structure (ball joint structure):

[0500] like Figure 45 and 46 As shown, the upper end of the ball head 50, ball head 50-1, is ball-jointed (or forms a spherical bearing structure) with the module heat source 3. The lower end of the ball head 50 extends into the mounting hole 52. The ball head 50 can move up and down relative to the mounting hole 52. A tension spring 51 or a top spring is also provided in the mounting hole 52. If it is a tension spring 51, the tension spring 51 is sleeved on the part of the ball head 50 that extends into the mounting hole 52. The upper end of the tension spring 51 contacts or connects with the top inner wall of the mounting hole 52, and the lower end of the tension spring 51 is connected to the nut 50-2 at the lower part of the ball head 50 (e.g., Figure 45 , 46As shown, when the bottom of the inner box is tilted, the upper ball head 50-1 of the module heat source 3 adjusts adaptively. At this time, the ball head screw 50 is pressed downwards, and the tension spring 51 is stretched. Through the action of the tension spring 51 and the upper ball head 50-1, the module heat source 3 is brought into contact with the bottom of the inner box. If a top spring is used, it is located at the bottom of the ball head screw 50, with its upper end connected to the nut 50-2 at the bottom of the ball head screw 50, and its lower end connected to the bottom of the mounting hole 52. (When the bottom of the inner box is tilted, the upper ball head 50-1 of the module heat source 3 adjusts adaptively. At this time, the ball head screw 50 is pressed downwards, and the top spring is compressed. Through the action of the top spring and the upper ball head 50-1, the module heat source 3 is brought into contact with the bottom of the inner box.)

[0501] In this method, the upper ball joint 50-1 of the ball joint screw 50 can be hinged to the module heat source 3 in many ways, for example:

[0502] Form 1: such as Figure 45 As shown, the heating module may include a heating panel 37, heating components, and a heat insulation mounting plate 39. The heating panel 37 and the heat insulation mounting plate 39 are installed together. Heat insulation silicone 40 may be provided between the heating panel 37 and the heat insulation mounting plate 39. Then, the ball head screw 50 passes through the clearance hole 39-A of the bottom plate of the heat insulation mounting plate 39 and is ball-hinged with the heating panel 37.

[0503] Form 2: For example: Figure 46 As shown, the heating module may include a heating panel 37, heating components, and a heat-insulating mounting plate 39, etc. The heating panel 37 and the heat-insulating mounting plate 39 are installed together, and heat-insulating silicone 40 can be provided between the heating panel 37 and the heat-insulating mounting plate 39. Then, the ball head screw 50 is directly ball-jointed to the bottom plate of the heat-insulating mounting plate 39.

[0504] Alternatively, it can be implemented in any other possible form.

[0505] In addition, for further processing of the lunch box, a steamer can also be included, which is used in conjunction with the inner box 16.

[0506] The steamer (usually a plate-shaped or bowl-shaped structure formed by the side walls and bottom) is used in conjunction with the inner box 16 as follows:

[0507] The first form of the steamer and inner box 16 are as follows: Figure 17-10 As shown, steamers 16-21 and 16-23 (16-21 and 16-23 are two different types of steamers) have outward-curving opening edges 16-21-A at the top. The opening edge (upper surface) of the steamer does not exceed the upper surface of the opening edge 16-1-5 of the inner box 16-1. Figure 17-12As shown, a stepped edge 16-A can be provided inside the inner box 16-1 (possibly at the top). The opening edge 16-21-A of the steamer rests on the stepped edge 16-A. Then, the sealing film 16-3 covers the opening of the inner box 16-1, with the four sides of the sealing film 16-3 pressed against the opening edge 16-1-5 of the inner box 16-1. This seals the opening of the inner box 16-1 (the sealing film has vent holes) and also seals the steamer inside the inner box 16-1. In this configuration, the steamer has ventilation holes, which can take one or more of the following forms:

[0508] The first type of ventilation hole: one or more holes can be directly set at the bottom of the steamer to facilitate ventilation; the second type of ventilation hole: such as Figure 17-10 and Figure 17-12 As shown, a notch 001 is formed on the end side wall of steamers 16-21 and 16-23. The notch 001 facilitates ventilation and makes it easy to remove the steamer. At this time, there is a gap between the upper surface of the steamer and the sealing film 16-3. The third type of ventilation hole: the side wall of the steamer is provided with through holes to facilitate ventilation.

[0509] The above-mentioned steamer can be as follows: Figure 17-10 The diagram shows small steamers 16-23 placed inside the inner box. One or multiple steamers can be placed inside. The large steamer 16-21, located outside the inner box, is typically only needed once. Figure 17-12 This is based on a large steamer.

[0510] A second form of cooperation between the steamer and the inner box 16: An outwardly flared opening edge 16-21-A is provided at the top of the steamer, which rests on the opening edge 16-1-5 of the inner box 16-1, as shown below. Figure 17-13 , 17-14 As shown, a sealing ring 00B can be installed between the opening edge 16-21-A of the steamer and the opening edge 16-1-5 of the inner box 16-1. A sealing film 16-3 is made at the opening of the steamer. When in use, the pressure ring 15-2-5 of the box lid presses against the position corresponding to the opening edge 16-21-A of the steamer. In this form, the steamer is provided with ventilation holes, which can be one or more of the following types:

[0511] The first type of ventilation hole: one or more through holes can be set directly at the bottom of the steamer to facilitate ventilation; the second type of ventilation hole: through holes are set on the side wall of the steamer to facilitate ventilation.

[0512] A third form of cooperation between the steamer and the inner box 16: An outward-curving opening edge 16-21-A is provided at the top of the steamer, which rests on the opening edge 16-1-5 of the inner box 16-1, as shown below. Figure 17-15 As shown, the opening edge of the steamer 16-21-A is narrower than the opening edge of the inner box 16-1 16-1-5 (the so-called narrower is as follows). Figure 17-15 The steamer opening shown is short along the left-right direction of 16-21-A, so that from... Figure 17-15 As can be seen, the opening edge of the steamer 16-21-A is recessed by one ring compared to the opening edge 16-1-5. Therefore, when the steamer opening edge 16-21-A rests on the opening edge 16-1-5 of the inner box 16-1, a ring of the inner box 16-1-5 will still be exposed. Then, the edge of the sealing film 16-3 is sealed to the exposed part of the opening edge 16-1-5 of the inner box 16-1 (this is a closed connection). Finally, the pressure ring 15-2-5 of the lid presses down on the position corresponding to the steamer opening edge 16-21-A, or the pressure ring 15-2-5 presses down on the position corresponding to the exposed part of the opening edge 16-1-5 of the inner box 16-1. Figure 17-15 It is pressed against the exposed part of the opening edge 16-1-5 of the inner box 16-1); in this form, the steamer is provided with ventilation holes, which can be one or more of the following forms:

[0513] The first type of ventilation hole: one or more through holes can be directly set at the bottom of the steamer to facilitate ventilation; the second type of ventilation hole: a notch 001 is formed on the end side wall of the steamer 16-21 and 16-23. The notch 001 can facilitate ventilation and also make it easy to remove the steamer. At this time, a gap is left between the upper surface of the steamer and the sealing film 16-3; the third type of ventilation hole: through holes are set on the side wall of the steamer to facilitate ventilation.

[0514] The above-mentioned steamer can be as follows: Figure 17-10 The diagram shows small steamers 16-23 placed inside the inner box. One or multiple steamers can be placed inside. The large steamer 16-21, located outside the inner box, is typically placed close together. Figure 17-12 This is based on a large steamer.

[0515] The fourth form of the steamer and inner box 16 are as follows: Figures 17-16 to 17-25As shown, the top of the steamer 16-21 (taking a large steamer 16-21 as an example, as this design is more suitable for large steamers 16-21) has an outward or inward folding opening edge 16-21-A. In use, the sealing film 16-3 connects to the opening edge 16-21-A, and the pressure ring 15-2-5 of the lid presses down on the corresponding position of the steamer opening edge 16-21-A. Then, the bottom or side wall of the steamer 16-21 is secured to the opening edge 16-1-5 of the inner box 16-1. Figures 17-16 to 17-19 As shown, this is one form where the side wall of the steamer is engaged with the opening edge 16-1-5 of the inner box 16-1. In this form, a stepped platform 16-21-B is provided on the side wall of the steamer, and this stepped platform 16-21-B is engaged with the opening edge 16-1-5 of the inner box 16-1. At this time, a sealing ring 00B can be provided between the stepped platform 16-21-B and the opening edge 16-1-5 of the inner box 16-1. In this form, a portion of the bottom of the steamer 16-21 extends into the inner box 16-1. At this time, a vent is provided on the steamer, and the vent can take one or more of the following forms:

[0516] The first type of ventilation hole: one or more through holes can be directly set at the bottom of the steamer to facilitate ventilation; the second type of ventilation hole: through holes are set on the side wall of the steamer to facilitate ventilation (in this type of ventilation hole, the side wall of the steamer below the stepped platform 16-21-B should not be in close contact with the inner wall of the inner box 16-1, such as...). Figure 17-18 and Figure 17-19 wait).

[0517] like Figures 17-20 to 17-23 As shown, another form is where the side wall of the steamer is secured at the opening edge 16-1-5 of the inner box 16-1. In this form, a retaining ring 16-21-C is provided on the side wall of the steamer, which is secured at the opening edge 16-1-5 of the inner box 16-1. A sealing ring 00B can be provided between the retaining ring 16-21-C and the opening edge 16-1-5 of the inner box 16-1. In this form, a portion of the bottom of the steamer 16-21 extends into the inner box 16-1. In this case, a vent is provided on the steamer, and the vent can take one or more of the following forms:

[0518] The first type of ventilation hole: one or more through holes can be directly set at the bottom of the steamer to facilitate ventilation; the second type of ventilation hole: through holes are set on the side wall of the steamer to facilitate ventilation (in this type of ventilation hole, the side wall of the steamer below the stepped platform 16-21-B should not be in close contact with the inner wall of the inner box 16-1, such as...). Figure 17-20 and Figure 17-21 wait).

[0519] like Figures 17-24 to 17-25As shown, the bottom of the steamer is fitted into the opening edge 16-1-5 of the inner box 16-1. In this form, the bottom of the steamer is pressed against the opening edge 16-1-5 of the inner box 16-1. A sealing ring 00B can be set between the bottom of the steamer and the opening edge 16-1-5 of the inner box 16-1. At this time, a vent hole is set at the bottom of the steamer.

[0520] like Figures 31-33 As shown, the exhaust pipe 4 is connected to the steam recovery system, which includes a recovery shell 25 (containing a heat exchange fluid, such as water), steam heat exchange tubes 26, and refrigerant pipes 27. The steam heat exchange tubes 26 are located inside the recovery shell 25, with the upper part of the steam recovery tubes 26 connected to the upper part of the exhaust pipe 4. The lower end of the steam heat exchange tubes 26 is a condensate outlet (the condensate outlet is connected to the tailwater collection tank 30 via pipe 26-2). Figure 31 The 31 in the diagram is the heat exchange fluid drain pipe, which is connected to the inside of the recovery shell 25 via a valve; the refrigerant pipe 27 extends into the recovery shell 25, and the refrigerant pipe 27 (with built-in refrigerant) is connected to the refrigeration system (e.g., Figure 25-4 As shown, the condenser column is the refrigerant pipe 27.

[0521] The outer wall of the further steam heat exchange tube 26 is provided with fins 26-1 (similar to the fins on a radiator, which makes heat exchange more efficient).

[0522] Furthermore, the steam recovery system also includes a circulating water pump. The inlet pipe 28 and outlet pipe 29 of the circulating water pump extend into the recovery housing 25. (Generally, the inlet pipe 28 extends into the lower part of the recovery housing 25, and the inlet pipe 28 is usually located in the upper part of the recovery housing 25. That is to say, the water inlet at the bottom of the inlet pipe 28 is lower than the water outlet at the bottom of the outlet pipe 29, similar to the circulating water pump in a fish tank. Its function is to act as a turbulence pipe to prevent the temperature from getting too low and freezing. Generally, two circulating water pumps can be set up. Through the action of the two pumps, the lower water and the upper water will circulate.) Figure 31 The number 4-2 in the diagram is the exhaust branch pipe 4-2, which is connected to the delivery and shipping warehouse 2; the number 33-1 is the refrigerant inlet of refrigerant pipe 27, and the number 33-2 is the refrigerant outlet of refrigerant pipe 27. The refrigerant inlet and refrigerant outlet are connected to the refrigeration system.

[0523] In addition, such as Figure 32As shown, the exhaust pipe 4 includes an exhaust branch pipe 4-2 and an exhaust riser 4-3. The bottom of the exhaust riser 4-3 (which is a single riser) has an outlet (i.e., a steam condensate overflow port 4-A), and the bottom of the exhaust riser 4-3 also has a U-shaped water trap 4-B. (Similar to a toilet's water trap, meaning the bottom of the exhaust pipe 4 also has an outlet for steam condensate, which is discharged through the U-shaped water trap 4-B and the steam condensate overflow port 4-A. The function of the water trap is to isolate steam.) The steam condensate overflow port allows steam that has liquefied prematurely in the exhaust riser 4-3 before entering the condenser to be discharged to the tailwater collection tank 30. Generally, as shown in Figure 32, where the arrows indicate the overall steam flow, steam is discharged from the delivery and unloading compartment 2. Steam enters exhaust branch pipe 4-2 (a slope is typically installed on this section of pipe from delivery and unloading hopper 2 to facilitate the drainage of condensate), and then enters exhaust riser pipe 4-3 (ideally, there should also be a slope when exhaust branch pipe 4-2 connects to exhaust riser pipe 4-3; this slope generally gradually slopes downwards from the end furthest from exhaust riser pipe 4-3 until it finally connects to exhaust riser pipe 4-3, meaning the end of exhaust branch pipe 4-2 connecting to exhaust riser pipe 4-3 is lower than the end of exhaust branch pipe 4-2 furthest from exhaust riser pipe 4-3). After entering exhaust riser pipe 4-3, the steam mainly rises, and some condensed steam is discharged from the bottom of exhaust riser pipe 4-3 through U-shaped backflow bend 4-B. The rising steam enters the steam heat exchanger tube 26 from the top. At this point, because the steam heat exchanger tube 26 is located inside the recovery shell 25 and the recovery shell 25 is filled with heat exchange fluid, For example, water, combined with the cooling effect of refrigerant pipe 27, cools the heat exchange liquid, causing the steam entering the steam heat exchange tube 26 to be condensed into water, which is then discharged from the bottom pipe 26-2 to the tailwater collection tank 30, completing steam recovery.

[0524] Furthermore, for the lunchbox, the outer casing 15 is provided with a support frame 15-5 to support the inner box 16 (the support frame 15-5 can be directly fixed to the outer casing 15, or it can be separate; in use, it is fastened to the upper end of the outer casing 15 or clipped inside the outer casing 15. In the form of clipping inside the outer casing 15, the position of the support frame 15-5 can generally be lower than the upper edge of the inner box 16), and the support frame 15-5 has a support opening 15-5-1 for the inner box 16 to pass through; Figure 8 , 9-1As shown in Figure 10-2, when in use, the inner box (16) is placed into the support opening 15-5-1 and the outward opening at the upper end of the inner box 16 overlaps around the opening of the support opening 15-5-1 along 16-1-5 to support the inner box 16; or the inner box 16 is made into a structure that gradually shrinks from top to bottom, and then the side wall of the inner box (16) directly blocks the support opening 15-5-1. That is to say, in the process of gradually putting the inner box 16 in, the inner box 16 will be gradually blocked by the support opening.

[0525] Furthermore, for delivery and payment storage location 2, an infrared detection device is installed in delivery and payment storage location 2 to determine whether items are placed in delivery and payment storage location 2 (the infrared detection device is existing technology and can be purchased and applied directly).

[0526] An air guide slope 5-7 is also installed inside the air duct 5-3, which corresponds to the air inlet door 5-1. (e.g.) Figure 25-1 , Figure 25-2 As shown, the guide slope (5-7) is a slope that gradually slopes towards the air inlet from bottom to top, or as shown in the image. Figure 25-3 The concave arc-shaped surface shown primarily serves to guide airflow.

[0527] The working principle of the aforementioned community-based intelligent meal delivery workstation is explained below:

[0528] In use, the central control module controls the motor 11 inside the door 9 of the corresponding delivery and distribution compartment 2 to rotate the output gear 11-2 or the output friction wheel. This causes the output gear 11-2 to mesh with the rack 9-3, or the output friction wheel to rub against the friction strip, thereby opening the corresponding compartment door. Then, the meal box is placed into the delivery and distribution compartment 2, causing the rack 15-1-1 (or friction strip) and slide rail 15-1-5 at the bottom of the meal box to enter the slide groove 7-1. The food is gradually fed into the delivery and distribution compartment 2 until the rack 15-1-1 engages with the drive wheel 14-1 of the delivery motor 14, or the friction strip on the bottom of the food container rubs against the friction wheel of the delivery motor 14. The rotation of the delivery motor 14 automatically pulls the food container into the delivery and distribution compartment 2 (the heated area D at the bottom of the food container contacts the module heat source 3), causing the magnetic plate 12-1-2 to engage with the magnetic suction port 12-2 on the food container (this example uses a magnetic suction port 12-2 on the food container's exhaust duct). The suction engages, connecting the exhaust duct 17 of the food container to the exhaust pipe 4. Then, the motor 11 inside the door 9 reverses, closing the door. If the food in the delivery compartment 2 needs to be refrigerated, the refrigeration system is activated, allowing cold air to enter through the air inlet and refrigerate the food container. The cold air then returns through the air outlet until refrigeration is complete, at which point the user removes the food container. If the food needs to be cooked on-site, for example, if it's rice, raw rice and an appropriate amount of water are placed in the inner box 16-1 of the inner box 16 before packaging; if it's braised pork or stewed green beans, raw or semi-finished ingredients, seasonings, and an appropriate amount of water are placed in the inner box 16-1 beforehand. 1. If steaming buns, pour an appropriate amount of water into the lower cavity BB inside the inner box 16-1, then place the perforated partition 16-1-1 inside, and then place the wrapped raw buns or frozen raw buns on the perforated partition 16-1-1 inside the inner box 16-1; generally, the inner box 16-1 of the lunch box can be two, one for staple food and one for vegetables, for example, one for raw rice (to be cooked into rice), and the other for ingredients for braised pork and green beans (to be cooked into braised pork and green beans). After the above preparation is completed, seal the opening of the inner box 16-1 with the sealing film 16-3, then place the entire inner box 16 inside the outer box 15-1, and then close the top cover 15-2 (or the food container 15-2-1). After the filling is inserted, it is snapped together with the top cover 15-2 (the specific form is as described above, and will not be repeated here), so that the elastic spherical cavity 17-1 presses against the sealing film 16-3, and the cavity exhaust port 17-2 at the bottom of the elastic spherical cavity 17-1 corresponds to the exhaust hole 16-3-1 on the sealing film 16-3; During on-site cooking, the heat source 3 of the control module heats the heating area D at the bottom of the inner box;In hot summer weather, the cooling fan can be turned on before the preset cooking time to keep the food container chilled and ensure freshness. If the weather is not very hot, or the cooking time is not far away, the cooling fan can be turned off. Choose according to your needs. If the cooling fan is on, it can be turned off when the preset cooking time is reached, or cooking can continue with the cooling fan on. According to the preset time, the central control module controls the heat source 3 to cook the food inside the inner container 16 (the cooking principle is similar to that of a rice cooker or induction cooker). The steam generated by the cooking inside the inner container 16-1 is discharged through the vents on the sealing film 16-3.

[0529] The overall control method of the present invention will be described below:

[0530] (1) The product management terminal generates a food configuration list based on food demand data and matches the information in the configuration list to the configured food lunch boxes.

[0531] In this step, the cloud management center receives food demand information generated by users through a client (such as a mobile phone or computer), matches the corresponding delivery and distribution warehouse 2 based on the community intelligent meal distribution workstation, generates food demand data, and then distributes it to the product management end and the logistics management end.

[0532] (2) The meal box is placed into the matched delivery and distribution warehouse 2, and the delivery and distribution warehouse (2) performs on-site operations. In this step, the product management terminal configures raw food, semi-raw food or cooked food according to the food configuration list, and at the same time inputs the food configuration list information into the RFID code on the food meal box to complete the meal box configuration.

[0533] Furthermore, in step (2) above, the product management terminal (food distribution center) generates a food configuration list based on food demand data. The product management terminal configures raw, semi-raw, or cooked foods according to the food configuration list, and simultaneously inputs the food configuration list information into the RFID code on the food container to complete the container configuration. The raw and semi-raw foods mentioned here are the raw rice, braised pork, dried green beans, etc. mentioned above. Then, the configuration list information is combined with the configured food container. Furthermore, a food order sticker with the order number is affixed to the container.

[0534] Furthermore, after step (2) above, the logistics management end places the meal box into the matching delivery and payment warehouse 2 on the community smart meal distribution workstation.

[0535] The above (2) steps are carried out on-site; including refrigeration, freezing, cooking, on-site cooking in refrigeration or on-site heating in refrigeration environment at a time.

[0536] Timed on-site cooking or heating in a refrigerated environment refers to the introduction of cold air into the delivery and distribution compartment 2 through the air vent 5 (to ensure that food is stored in a refrigerated environment when heating or cooking is not required, thus ensuring quality). When the time for cooking food is reached, the module heat source 3 at the bottom of the delivery and distribution compartment 2 is controlled by the central control module to heat the bottom of the food container (inner box 16). During the heating process, cold air is continuously introduced, and the amount of cold air introduced is adjusted by the central control module to maintain the temperature in the delivery and distribution compartment 2 (a temperature sensor is installed in the delivery and distribution compartment 2).

[0537] Once the food is in place, it can send a placement information to the client. If the food needs to be cooked on a timer, it can also send the food cooking completion time. After the food is cooked, it can also send a cooking completion information. This information can be sent by the cloud management center. In other words, the corresponding delivery and payment warehouse 2 will send the placement or cooking completion information back to the cloud management center, which will then send it to the client. Alternatively, it can be sent directly by the central control module of the community smart meal distribution workstation.

[0538] The above-mentioned method of placing the meal box into the matching delivery and distribution compartment 2 on the community smart meal distribution workstation is one of the following methods: Method 1: The logistics personnel deliver the food meal box to the community smart meal distribution workstation and enter the order number of the food configuration order or scan the radio frequency code on the food meal box to make the door of the delivery and distribution compartment 2 open automatically. The delivery personnel place the meal box into the delivery and distribution compartment 2 and close the door.

[0539] Method 2: The logistics personnel deliver the food containers to the community smart meal distribution workstation and enter the order number of the food configuration order or scan the radio frequency code on the food container to display the location of the delivery and distribution warehouse 2 corresponding to the container (for example, it can display a number or display it through a location indicator. The location display is to display the distribution of the entire delivery and distribution warehouse 2 in the form of an image and then mark the corresponding location). Then, the delivery personnel manually open the corresponding warehouse door according to the displayed location of the delivery and distribution warehouse 2, place the food container into the delivery and distribution warehouse (2), and manually close the warehouse door.

[0540] The above-mentioned raw food preparation mainly takes one of the following methods:

[0541] The first method involves the preparation of staple food and side dishes. The staple food preparation includes pasta preparation and raw rice preparation. The pasta preparation involves placing a partition 16-1-1 inside the inner box 16-1 and adding water under the partition 16-1-1. The prepared raw pasta is then placed on the partition 16-1-1 inside the inner box 16-1, and a sealing film 16-3 is set at the opening at the top of the inner box 16-1 (mainly for on-site steaming, such as steamed buns, dumplings, steamed bread, etc.).

[0542] The raw rice is prepared by placing the raw rice directly into the inner box 16-1 and adding enough water to cook the rice (the inner wall of the inner box 16-1 can be marked with corresponding scales), and then sealing the opening at the top of the inner box 16-1 with a sealing film 16-3.

[0543] The dish is prepared by placing lettuce or semi-lettuce into the inner box 16-1 and adding enough water and seasonings to cook the lettuce. Then, a sealing film 16-3 is placed at the opening at the top of the inner box 16-1.

[0544] The second method: raw food, which does not require cooking (such as frozen meat, frozen shrimp, etc. that need to be cooked at home), is placed directly into the food container.

[0545] The food demand data mentioned in step (1) above includes the specific details of the food (variety, type, for example: what staple food, what dishes, etc.), the location of the delivery and distribution warehouse 2 that needs to be delivered, how to preserve it (frozen, refrigerated or insulated, etc.), and the time or time period when the food needs to be eaten.

[0546] In step (1) above, the user uses a client terminal (which can be an existing terminal such as a mobile phone or computer) to form food demand information (select the food needed, the address to be delivered, and the time or time period to be eaten, which is generally the time period to be eaten, leaving room for error time in the middle of delivery. The user can also choose to set the start time of cooking. For example, after the food box is in place, the information of the position is sent to the user terminal, and the user then selects the start time of cooking according to their own needs). It is similar to the existing ordering mode, but the most important difference is that the existing ordering mode is to make finished products and then deliver them directly. The production process is completed directly on the product management terminal without any on-site operation. Therefore, it does not include the dining time. However, this application includes the dining time because this application can cook raw food or semi-finished products on-site. After confirmation, the data is uploaded to the cloud management center. The cloud management center matches the corresponding delivery and delivery warehouse 2 to form food demand data and transmits the data to the product management terminal (food distribution center terminal) and the logistics management terminal.

[0547] In step (2) above, the delivery personnel place the meal box into the delivery and payment compartment 2. If the food needs to be cooked at a time, the vent of the meal box needs to be connected to the vent pipe 4. Then close the door, and the central control module will perform corresponding operations on the meal box according to the food demand data corresponding to the meal box (refrigeration, cooking or cooking in a timed refrigerated state).

[0548] The invention will be further described below with reference to examples:

[0549] Example 1:

[0550] Cabinet 1 is equipped with one (or two, or three) delivery and distribution compartments 2. This is suitable for home use. In this method, a refrigeration system is not required. Users order food through a mobile app and specify their dining address. The cloud management center will automatically match the delivery and distribution compartment 2 in the user's home. After the delivery personnel from the logistics management terminal deliver the food, the user scans the code to open the compartment door, places the food container into the delivery and distribution compartment 2, and then closes the compartment door. At this time, the delivery and distribution compartment 2 can heat the food container according to a preset time, or after the food container is in place, the user can choose the specific cooking time according to their own needs.

[0551] Of course, in this method, the food cooking data can also be pre-loaded into the community's smart meal preparation workstation, and then it can be updated online regularly. In this case, the network can be disconnected. The operation is similar to that of a household microwave oven. After the food container is placed in, the cooking mode is manually turned on. After cooking is finished, an alarm device will indicate that cooking is complete, and then it will switch to the keep-warm state.

[0552] Example 2:

[0553] This embodiment may also have the following specific implementation methods:

[0554] Implementation method (1):

[0555] This implementation method is generally applicable to open communities, gated residential areas, office lobbies, and medium to large-sized factory areas, etc., and its form is as follows: Figure 1 As shown, cabinet 1 is equipped with multiple delivery and unloading compartments 2, arranged in horizontal rows, with a set of air dampers in each row. The working process of this method is as follows: Method 1:

[0556] When a user orders food on the client, the data is uploaded to the cloud management center. The cloud management center will match the corresponding delivery and payment warehouse 2 according to the user's location. For example, if the user's dining address is in office building A, the cloud management center will match the nearest delivery and payment warehouse 2. After the delivery and payment warehouse 2 is matched, the cloud management center will form food demand data together with the user's food demand information and distribute it to the product management terminal and logistics management terminal.

[0557] The product management system generates a food configuration list and prepares the food accordingly. For example, if a customer orders rice and braised eggplant with meat, as shown in Figure 9, the food container has two inner boxes 16. Raw rice and enough water to cook the rice are added to one inner box 16. The rice is supported by a partition 16-1-1 to prevent it from sticking to the bottom (alternatively, the partition 16-1-1 can be omitted). The top of the inner box is then sealed with a sealing film 16-3. The other inner box 16 contains the prepared raw eggplant, raw meat, seasonings, and enough water to cook the eggplant and meat. Again, the raw eggplant and meat are supported by the partition 16-1-1 to prevent them from sticking to the bottom (alternatively, the partition 16-1-1 can be omitted). The top of the inner box is then sealed with the sealing film 16-3. Both inner boxes are then placed inside the outer box 15-1, and the food can be placed in the food receiving slot 15-2-1. Place some side dishes inside, such as pickles, mixed vegetables, cold dishes, etc., then seal the food container 15-2-1 with plastic wrap, and as follows: Figure 8 and 10-1 The lid is then placed upside down on the top cover 15-2, and then the top cover 15-2 is placed on the inner box 16. This ensures that when the elastic spherical cavity 17-1 is in use, it presses against the sealing film 16-3, aligning the cavity's vent with the vent hole on the sealing film 16-3. Simultaneously, other parts of the spherical cavity 17-1 press against the area around the vent hole (including the breathing hole), completing the food preparation. At the same time, the preparation information is entered into the RFID code on the meal box. Logistics personnel deliver the meal box to the designated community smart meal distribution workstation. By scanning the RFID code on the meal box or entering the order number (the order can be pasted on the meal box), the logistics personnel automatically open the door of the pre-configured delivery and payment compartment 2. (The central control module controls the output gear 11-2 to rotate, causing the output gear 11-2 to mesh with the rack 9-3.) (And drive the door to open), or display the location of delivery compartment 2. Manually open the door and place the entire meal box into delivery compartment 2. At this time, the central controller controls the drive wheel 14-1 to rotate (the drive wheel 14-1 starts rotating the moment the automatic door opens, or if the door is opened manually, the drive wheel 14-1 starts rotating after scanning the RFID code on the meal box or entering the order number), slowly pushing the meal box into delivery compartment 2, causing the rack 15-1-1 (using the rack as an example here) and the slide rail 15-1-5 to move within the slide groove 7-1. When the rack 15-1-1 contacts the drive wheel 14-1, the drive wheel 14-1 meshes with the rack 15-1-1 at the bottom of the meal box, causing the meal box to automatically move into delivery compartment 2 until it moves to the desired location. Figure 10-1At the indicated position, (slide rail 15-1-5) touches the limit switch 19, causing the pallet motor 14 to stop, and the meal box is positioned. At this time, the magnetic suction piece 12-1-2 engages with the magnetic suction port 12-2 (on the meal box), connecting the exhaust pipe 4 with the meal box exhaust duct 17. (At this time, the infrared detection device detects the placed item). The central control module controls the output gear 11-2 to reverse, causing the output gear 11-2 to mesh with the rack 9-3 and close the door. If the customer needs to start cooking at 11:00 AM, the meal box will be in place by 10:30 AM. Between 10:30 AM and 11:00 AM, cold air is introduced into the delivery and distribution compartment 2 through the air vent 5 to maintain a refrigerated temperature, keeping the food fresh, which is especially important in the hot summer. The temperature in the delivery and distribution compartment 2 can be controlled by temperature sensors, etc. Thus, before 11:00 AM, the entire meal box is stored in the refrigerated environment of the delivery and distribution compartment. At 11:00 AM... When the time is up, the central control module of the community smart meal delivery workstation controls the corresponding delivery and distribution warehouse's module heat source 3 to start cooking the meal boxes (the cooking time, temperature, etc., are executed according to a pre-set program; this program data can be pre-set in the community smart meal delivery workstation or pre-stored in the cloud management center, and the cloud management center can directly control the community smart meal delivery workstation to execute it. Module heat source 3 can also be equipped with an over-temperature protection device to prevent the module heat source 3 from overheating). Module heat source 3 can also use an existing electric heating source; simply turn on the power, as will not be elaborated upon. During the cooking process, steam is discharged through the vent on the sealing membrane 16-3, discharged through the exhaust pipe 4, and recovered using the steam recovery system (the steam recovery process is as follows...). Figures 31 to 33 As shown, steam comes out of the food container, passes through the exhaust branch pipe 4-2 and the exhaust riser pipe 4-3, and then enters the steam heat exchange tube 26 for heat exchange, turning into condensate. The condensate is then discharged to the tailwater collection tank 30 through the lower condensate outlet.

[0558] The entire cooking process can be carried out in a refrigerated environment, which will not affect the side dishes inside the lid (15-2), nor will it affect other ordered food items in the community smart meal distribution workstation. After cooking is completed, the central control module can send a cooking completion message to the user's client (or the cloud management center can send it), or the customer can directly pick up the food according to the pre-received estimated completion time. Alternatively, the customer can pre-set only the meal time, and the cloud management center will automatically pre-set the cooking time according to the food category to ensure that the customer can directly pick up the cooked food at the pre-set time. For example, if the customer orders rice and eggplant stew, cooking rice takes 10 minutes and cooking eggplant stew takes 20 minutes (these times are pre-set by the system based on the ingredients), then the community smart meal distribution workstation will start cooking eggplant stew 25 minutes before the customer's meal (generally, some time needs to be reserved and set in advance; in this example, 5 minutes in advance is used as an example) after the meal box is in place, and start cooking rice 15 minutes before the meal. After both are cooked, it will enter a 5-minute keep-warm state (which can be achieved through temperature adjustment of the module's heat source).

[0559] Additionally, if the food container is delayed due to deviations in the intermediate logistics process, preventing the cooking from starting at the pre-required time or the pre-set completion time from being completed, the cloud management center will send the food container placement information to the user's end. The user can then readjust the start cooking time or the desired completion time (the cloud management center can usually provide a reference for the fastest completion time based on instant cooking; the user can choose to complete the cooking at that time or choose to postpone it).

[0560] When using the delivery area, scanning the code or entering the order number opens the door and simultaneously reverses the storage motor, causing the food container to exit the delivery and checkout compartment 2. After the container is removed, an infrared detector detects that the item has been taken out, and the central control module then closes the door. To consume the food, the user simply removes the inner container 16-1 and tears off the sealing film 16-3.

[0561] Implementation method (2):

[0562] If frozen food is required (one or two floors of the entire community smart meal delivery workstation can be set up for storing frozen food only), the user can place an order through the client application. After selection, the data is uploaded to the cloud management center. The cloud management center matches the corresponding delivery and distribution warehouse 2, and then generates food demand data. This data is distributed to the product management end and the logistics management end. The product management end generates a food configuration list and prepares the food according to the information (or directly packages frozen foods, such as frozen shrimp and frozen meat). After the frozen food is packaged, it is directly transported by logistics to the designated delivery and distribution warehouse. The central control module then controls the corresponding delivery and distribution warehouse to blow cold air into the corresponding delivery and distribution warehouse through the air inlet to achieve freezing. (It should be noted that in a community smart meal distribution workstation with multiple layers and multiple delivery and distribution warehouses 2, sometimes it can be set up such that the top row of warehouses is for frozen food, the second row of warehouses is for fresh food, and the others are for heated or insulated food. Alternatively, it can be distinguished by columns, or by one or several delivery and distribution warehouses 2.) In this way, customers can pick up their food at any time without worrying about it melting or spoiling.

[0563] Implementation method (3):

[0564] If refrigerated food is required, the user places an order on the client-side. After selection, the data is uploaded to the cloud management center. The cloud management center matches the corresponding delivery and fulfillment warehouse 2, then generates food demand data. This data is distributed to the product management and logistics management ends. The product management end generates a food configuration list and prepares the food according to this information (e.g., if it is fresh fish, the product management end retrieves the live fish and processes it to create fresh fish meat; if it is fresh chicken, ...). Alternatively, live chickens can be retrieved and processed at the product management end to produce fresh chicken meat. (For fish, the processing involves standard procedures like scaling and gutting; for chicken, it involves standard procedures like plucking and gutting.) After packaging, the fresh food is directly transported by logistics to the designated delivery and distribution warehouse. The central control module then controls the corresponding delivery and distribution warehouse to receive cold air through the air inlet to achieve refrigeration. (It should be noted that in a multi-level community smart meal preparation workstation with multiple delivery and distribution warehouses, sometimes the top row of warehouses can be set up for frozen food, the second row for chilled food, and the others for food requiring heating or insulation. Alternatively, they can be distinguished by columns or by one or several delivery and distribution warehouses.) This way, customers can pick up their food at any time without worrying about it melting or spoiling, and can cook it directly at home, effectively maintaining the freshness of the ingredients.

[0565] In addition, in the above-mentioned implementation methods (2) and (3), if the order product is large, two adjacent delivery and distribution compartments 2 can be selected, and then the partition between the two adjacent delivery and distribution compartments 2 can be folded up, down, or toward the back panel to form a larger space, and then the order product can be placed in it.

[0566] This application is a community-based intelligent food delivery cabinet with intelligent preservation and storage and combined cooking and processing functions. This application can be linked to realize a wide variety of Chinese pre-prepared food (Chinese pre-prepared food: standardized clean vegetables and pre-prepared meals with strict delivery temperature and ready-to-eat quality requirements), and intelligent preservation and storage, intelligent cooking and processing, intelligent display and promotion, intelligent sales and delivery functions.

[0567] Delivery and payment bay 2 is the modular working unit of the delivery locker and the core of the delivery locker business. It can have functions such as freezing and refrigeration, intelligent preservation and storage; combined heating and automatic cooking and venting; in addition, it can also have transparent display and automatic display and promotion; and it also has functions such as combined orders, automatic delivery, and integrated services.

[0568] In addition, food packaging is also an important part of the delivery cabinet system. Food packaging is divided into two parts: one is the inner packaging (inner box) used directly for carrying and cooking food; such as aluminum foil food box plastic sealing packaging and PP plastic hot and cold food packaging, etc.

[0569] Secondly, there is the PP plastic outer packaging (outer shell) used for combining inner packaging of food and assisting in the venting function of food cooking; this series of lunch box packaging integrates cookware, tableware, and turnover packaging.

[0570] Furthermore, although exemplary embodiments of this disclosure are shown in the accompanying drawings, it should be understood that this disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this disclosure and to fully convey the scope of this disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0571] In summary, this application addresses the bottlenecks in the online distribution of industrialized short-shelf-life pre-packaged foods by employing a series of technical service measures, including intelligent data collection and aggregation of scattered orders from dense customer groups; standardized pre-packaged order production by central kitchens and fresh food processing enterprises; centralized distribution; and intelligent multi-temperature intelligent preservation storage, intelligent cooking and processing with multiple processes, and intelligent adaptation and delivery of multiple business combinations. These measures aim to improve the quality of online delivery of industrialized short-shelf-life pre-packaged foods, increase the efficiency of online distribution of industrialized short-shelf-life pre-packaged foods, reduce the cost of online distribution of industrialized short-shelf-life pre-packaged foods, and ensure the safety of online distribution of industrialized short-shelf-life pre-packaged foods.

[0572] Regarding consumer safety, consumers demand a closed and secure product distribution process with full transparency and informed consent. In terms of cost, consumers require reduced supply and delivery costs for small-value orders. Faced with a large volume of individual online orders, traditional food delivery methods can no longer meet consumer demands in terms of delivery range, quality, cost, timeliness, safety, and convenience. In particular, outdated food delivery technology has severely hampered the online distribution of chilled and fresh foods and fast food. Achieving wide-range, high-quality, efficient, streamlined, and low-cost offline delivery of online food orders is a crucial issue that the industry urgently needs to address, and this application effectively solves these problems.

[0573] This application can effectively realize operations such as refrigeration, freezing, cooking, timed on-site cooking in refrigeration or timed on-site heating in a refrigerated environment, and effectively realize intelligent meal preparation in communities, thus solving the problems that existed in the past.
