[0002] With the advancement of science and technology and the development of the economy, refrigerators have been widely used in people's lives. People have higher and higher requirements for the capacity of refrigerators. However, oversized refrigerators will increase the difficulty of transportation. Therefore, spliced ​​refrigerators have appeared. Spliced ​​refrigerators are refrigerators that use at least two single refrigerators side by side. After the refrigerators are spliced, they look like one refrigerator, which can meet the large-capacity needs of users such as shopping malls and is easy to carry. However, in the existing technology, it is impossible to determine the relative positions of the individual refrigerators after splicing, which is not conducive to refrigerator management.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0063] An embodiment of the present invention provides a spliced ​​refrigerator, comprising at least two single refrigerators, wherein the single refrigerators are spliced ​​side by side to form a spliced ​​refrigerator, and adjacent single refrigerators are connected to each other via cabinet interfaces, which are provided on the cabinet shell of the refrigerator, including a left interface and a right interface. It is worth noting that each single refrigerator can be configured with two cabinet interfaces (a left interface and a right interface), or a single refrigerator can be configured with only one interface, which can be configured according to actual conditions. For example, assuming that the spliced ​​refrigerator is composed of two single refrigerators, then each single refrigerator is configured with at least one interface to achieve refrigerator splicing communication. Generally, a cabinet interface is configured on the left and right sides of the refrigerator. Of course, a cabinet interface can also be configured on the back of the refrigerator. One cabinet interface of a single refrigerator can only be connected to one cabinet interface of another single refrigerator at most, and each single refrigerator realizes wired communication connection through the cabinet interface. See Figure 1 , Figure 1 This is a perspective view of a single refrigerator provided by an embodiment of the present invention. The single refrigerator of this embodiment has an approximately rectangular parallelepiped shape. The single refrigerator includes a box body 100 defining a storage space and a plurality of door bodies 200 provided at the opening of the box body 100. Figure 2 As shown, the door body 200 includes a door body shell 210 located on the outside of the box body 100, a door body liner 220 located on the inside of the box body 100, an upper end cover 230, a lower end cover 240, and an insulation layer located between the door body shell 210, the door body liner 220, the upper end cover 230, and the lower end cover 240; usually, the insulation layer is filled with foam. The box body 100 is provided with a chamber, wherein the chamber includes a component storage chamber for placing components in the refrigerator, such as a compressor, etc., and also includes a storage space for storing food, medicine, etc. In particular, each single refrigerator in the embodiment of the present invention includes an independent refrigeration system, see Figure 3The schematic diagram of the refrigeration system structure shown in the figure shows that the refrigeration system is arranged in the component storage cavity, including a compressor, an evaporator, a pressure reducer and a condenser. The refrigeration system is actually a refrigerant circuit, which circulates the refrigerant in sequence through the compressor, condenser, pressure reducer and evaporator to provide cooling for the compartments of the single refrigerator. The compressor is used to provide power for the refrigeration cycle of the single refrigerator; the storage space can be divided into multiple compartments, which can be configured as a refrigerator, a freezer, or a temperature-changing room (also known as a fresh-keeping room) according to different uses. Each compartment corresponds to one or more door bodies, for example, Figure 1 In the middle, the upper compartment is provided with a double door. The door can be pivotally arranged at the opening of the box body, or can be opened in a drawer-like manner to achieve drawer-like storage. Furthermore, each compartment is provided with at least one compartment sensor (not shown in the figure). Exemplarily, the compartment sensor is arranged on the inner wall of the compartment, and the probe of the compartment sensor is exposed to the storage space of the compartment to detect the real-time temperature of the compartment.

[0064] See also Figure 3 , Figure 3 This is a schematic diagram of the refrigeration system in a single refrigerator according to an embodiment of the present invention. The refrigeration system includes a compressor 1, a condenser 2, an anti-condensation tube 3, a filter drier 4, a pressure reducer 5, an evaporator 6, and a gas-liquid separator 7. The operating process of the refrigeration system includes compression, condensation, throttling, and evaporation.

[0065] Among them, combined Figure 3 The compression process is as follows: plug in the power cord of the refrigerator, when the contacts of the thermostat are connected, the compressor 1 starts to work, the low-temperature, low-pressure refrigerant is sucked into the compressor 1, and is compressed into a high-temperature, high-pressure superheated gas in the cylinder of the compressor 1 and then discharged into the condenser 2; the condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser 2, the temperature continues to drop, and is gradually cooled to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature, and the pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is as follows: the refrigerant after condensation After the saturated refrigerant liquid is filtered out of moisture and impurities by the drying filter 4, it flows into the pressure reducer 5 (such as a capillary tube), through which it is throttled and reduced in pressure, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is as follows: the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 6, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator 6 passes through the gas-liquid separator 7 and returns to the compressor 1 again, repeating the above process to transfer the heat in the refrigerator to the air outside the box, thus achieving the purpose of refrigeration. The flow direction of the refrigerant can also be seen in Figure 4 shown.

[0066] See also Figure 5As shown, the single refrigerator also includes a compartment fan 14, which allows air to continuously enter the fins of the evaporator 6 for heat exchange. At the same time, the air that has absorbed heat from the evaporator 6 and becomes cold is sent to the refrigerating chamber 11 and the freezing chamber 12 through the air duct 13. By utilizing the air outlets corresponding to the compartments, the air in the compartments is continuously circulated to achieve the purpose of lowering the temperature. The refrigerating air outlets provided on the inner wall of the refrigerating chamber include a refrigerating return air outlet and a refrigerating supply air outlet, which are used to form a cold air circulation to provide cooling to the refrigerating chamber. Similarly, the freezing chamber also has freezing air outlets (freezing supply air outlet and freezing return air outlet). When the compartment fan rotates, it generates airflow. The cooling energy generated by the evaporator is blown by the fan toward the air outlet along with the airflow, entering the compartment corresponding to the air outlet, providing cooling to the compartment. The air in the compartment is squeezed out and flows out from the corresponding air outlet, and is brought back to the evaporator for heat exchange, completing one airflow cycle.

[0067] Specifically, in an embodiment of the present invention, the spliced ​​refrigerator also includes a controller, which is used to: for the main refrigerator, control the first slave setting side interface of other single refrigerators to send the stored refrigerator ID and the location information associated with the refrigerator ID; control the second slave setting side interface of other single refrigerators to receive the refrigerator ID and the location information associated with the refrigerator ID and merge and store them with the refrigerator ID and location information of its own single refrigerator; wherein, the first slave setting side interface is a cabinet interface close to the main refrigerator, and the second slave setting side interface is a cabinet interface far away from the main refrigerator; wherein, the main refrigerator is one of the single refrigerators; control the setting side interface of the main refrigerator to receive the refrigerator ID of all other single refrigerators and the location information associated with the refrigerator ID as a location parameter; determine the relative positions between the single refrigerators according to the location parameters.

[0068] For example, see Figure 6 The schematic diagram of the connection relationship of the cabinet interface of the spliced ​​refrigerator shown in the figure assumes that the spliced ​​refrigerator is made by splicing four single refrigerators side by side. The four single refrigerators are refrigerator A, refrigerator B, refrigerator C, and refrigerator D. The corresponding ID information is ID1, ID2, ID3, and ID4. Each single refrigerator is equipped with a right interface (right transmission interface TX1 and right receiving interface RX1) and a left interface (left transmission interface TX2 and left receiving interface RX2). The single refrigerator with refrigerator ID ID2 is used as the main refrigerator for detailed introduction. Figure 7 , Figure 7 : is a first working flow diagram of a controller provided in one embodiment of the present invention, wherein the controller is configured to execute steps S11 to S15:

[0069] S11 , controlling the single refrigerator with the refrigerator ID being ID1 to send ID1 and the location information of ID1 to the left receiving interface RX2 of the single refrigerator with the refrigerator ID being ID2 through the right transmitting interface TX1 .

[0070] It can be understood that, if the single refrigerator with refrigerator ID ID2 is used as the main refrigerator, then the setting side interface of the single refrigerator with refrigerator ID ID2 includes the left interface and the right interface; the first slave setting side interface of the single refrigerator with refrigerator ID ID1 is the right interface, and since the single refrigerator (ID1) is the leftmost refrigerator, its left interface does not have any information sent from other single refrigerators; the first slave setting side interface of the single refrigerator with refrigerator ID ID3 and ID4 is the left interface, and the second setting side interface of the single refrigerator with refrigerator ID ID3 is the right interface. Since the single refrigerator with refrigerator ID ID4 is the rightmost refrigerator, its right interface does not have any information sent from other single refrigerators.

[0071] It is worth noting that the location information of ID1 is essentially the location information relative to the receiver (ID2). The relative position is determined by whether the interface receiving the information is the left interface or the right interface. For example, the location information of ID1 is received by the left interface of ID2, then the location information of ID1 is specifically expressed as: ID1 is on the left side of ID2.

[0072] S12, controlling the refrigerator whose ID is ID4 to transmit ID4 and the location information of ID4 to the refrigerator whose ID is ID3 via the left transmitting interface TX2;

[0073] It is worth noting that the location information of ID4 is essentially the location information relative to the receiver (ID3). For example, the location information of ID4 is received by the right interface of ID3. The location information of ID4 is specifically expressed as: ID4 is on the right side of ID3.

[0074] S13, controlling the refrigerator whose ID is ID3 to merge and store the received ID4 and the location information of ID4 with the refrigerator ID (ID3) and location information of its own refrigerator;

[0075] For example, a single refrigerator with the refrigerator ID ID3 may combine the received ID4 and the location information of ID4 with its own information and store them in a temporary cache queue, and then send them to ID3.

[0076] S14, controlling the single refrigerator with the refrigerator ID of ID3 to send the stored ID3, ID4, the location information of ID3 and the location information of ID4 to the right receiving interface RX1 of the single refrigerator with the refrigerator ID of ID2 through the left transmitting interface TX2;

[0077] It's worth noting that ID3's location information is essentially relative to the receiver (ID2). For example, ID3's location information is received by the right interface of ID2, and the specific location information of ID3 is: ID3 is to the right of ID2. Then, the information received by ID2 includes: ID1, ID3, and ID4. ID1 is to the left of ID2, ID3 is to the right of ID2, and ID4 is to the right of ID3.

[0078] S15. Control the refrigerator with ID ID2 to receive the received ID1, ID3, ID4, ID1 position information, ID3 position information and ID4 position information as position parameters, and determine the relative positions between the four refrigerators according to the position parameters.

[0079] In an optional embodiment, the controller is also used to: when the rightmost refrigerator of the spliced ​​refrigerator is the main refrigerator, screen out the leftmost refrigerator of the spliced ​​refrigerator according to the interface connection status of the obtained single refrigerator; wherein, the leftmost refrigerator is a single refrigerator whose left interface is not connected to other cabinet interfaces; control the right interface of the leftmost refrigerator to send the refrigerator ID and location information of the leftmost refrigerator to the left interface of the adjacent single refrigerator; control the other single refrigerators except the leftmost refrigerator to merge the refrigerator ID and location information associated with the refrigerator ID with the refrigerator ID and location information of their own single refrigerator after receiving the refrigerator ID and the location information, and send all the merged refrigerator IDs and location information associated with the refrigerator ID from the right interface to the left interface of the adjacent single refrigerator until the single refrigerator is the rightmost refrigerator of the spliced ​​refrigerator; wherein, the rightmost refrigerator is a single refrigerator whose right interface is not connected to other cabinet interfaces; determine the relative positions between the single refrigerators according to the refrigerator ID and location information received by the rightmost refrigerator.

[0080] For example, see Figure 8 and Figure 9 , Figure 8 is a second working flow diagram of a controller provided by an embodiment of the present invention, Figure 9 This is a schematic diagram of a method for identifying the position of a spliced ​​refrigerator provided by an embodiment of the present invention. The controller is also used to perform steps S15 to S18:

[0081] S15, obtaining the interface connection status of each single refrigerator, and selecting the leftmost refrigerator of the spliced ​​refrigerator according to the interface connection status;

[0082] S16, controlling the right interface of the leftmost refrigerator to send the refrigerator ID and location information of the leftmost refrigerator to the left interface of the adjacent single refrigerator;

[0083] S17: After receiving the refrigerator ID and the location information associated with the refrigerator ID, the other refrigerators except the leftmost refrigerator are controlled to merge the refrigerator ID and the location information with the refrigerator ID and the location information of the refrigerator itself, and send all the merged refrigerator IDs and the location information associated with the refrigerator ID from the right interface to the left interface of the adjacent refrigerator until the refrigerator becomes the rightmost refrigerator in the refrigerator. The rightmost refrigerator is a refrigerator whose right interface is not connected to any other cabinet interface.

[0084] It is worth noting that, in this embodiment, the main refrigerator is the rightmost refrigerator of the spliced ​​refrigerator, and all information is transmitted to the rightmost refrigerator for use in calculating the position between the individual refrigerators.

[0085] S18. Determine the relative positions of the individual refrigerators based on the refrigerator ID and location information received from the rightmost refrigerator.

[0086] It is understandable that the process of steps S15 to S18 corresponds to Figure 9 The left-direction information generation and transmission process relies on the interconnected cabinet interfaces to transmit the left refrigerator information from left to right to the rightmost refrigerator in sequence. For example, refrigerator A, refrigerator B, refrigerator C and refrigerator D each detect the communication status of their own interfaces to determine the interface connection status, and then determine that refrigerator A is the leftmost refrigerator in the spliced ​​refrigerator. Refrigerator A records its own ID and left-direction position information (at this time, the IC card of refrigerator A records the left-direction information: ID1 left 1), and then sends it to the second refrigerator on the left (refrigerator B). After the second refrigerator on the left receives the ID and left-direction position information of the first refrigerator on the left, it records The system records the IDs and corresponding positions of the two refrigerators, then sends the IDs and corresponding left-direction position information of the first and second refrigerators on the left to the third refrigerator on the left. (Refrigerator B's IC card now records the left-direction information: ID1 Left 1 & ID2 Left 2.) Similarly, the information of the third refrigerator on the left (Refrigerator C) is combined and recorded, and sent to the fourth refrigerator on the left (the rightmost refrigerator / Refrigerator D). Refrigerator C's IC card now records the left-direction information: ID1 Left 1 & ID2 Left 2 & ID3 Left 3, while Refrigerator D's IC card records the left-direction information: ID1 Left 1 & ID2 Left 2 & ID3 Left 3 & ID4 Left 4. The relative positions of the individual refrigerators can be inferred based on the information recorded on Refrigerator D's IC card.

[0087] In an optional embodiment, the controller is further configured to:

[0088] According to the obtained interface connection status of the single refrigerator, the rightmost refrigerator of the spliced ​​refrigerator is selected; wherein the rightmost refrigerator is a single refrigerator whose right interface is not connected to the interface of other cabinets;

[0089] Controlling the left interface of the rightmost refrigerator to send the refrigerator ID and location information of the leftmost refrigerator to the right interface of the adjacent single refrigerator;

[0090] Controlling the other single refrigerators except the rightmost refrigerator to merge the refrigerator ID and the location information associated with the refrigerator ID with the refrigerator ID and the location information of the single refrigerator itself after receiving the refrigerator ID and the location information, and sending all the merged refrigerator IDs and the location information associated with the refrigerator ID from the left interface to the right interface of the adjacent single refrigerator until the single refrigerator becomes the leftmost refrigerator of the spliced ​​refrigerator; wherein the leftmost refrigerator is a single refrigerator whose left interface is not connected to the interface of other cabinets;

[0091] The relative positions of the individual refrigerators are determined based on the refrigerator ID and position information received from the leftmost refrigerator.

[0092] For example, combined Figure 9 In this embodiment, the leftmost refrigerator is used as the main refrigerator to achieve the following Figure 9 The right-direction information shown is generated and transmitted, relying on the interconnected cabinet interfaces, and the information of the refrigerator on the right is transmitted from right to left in sequence to the leftmost refrigerator. For example, refrigerator A, refrigerator B, refrigerator C and refrigerator D each detect the communication status of their own interfaces to determine the interface connection status, and then determine that refrigerator D is the rightmost refrigerator in the spliced ​​refrigerator. Refrigerator D records its own ID and left-direction position information (at this time, the IC card of refrigerator D records the right-direction information: ID4 right 1), and then sends it to the second refrigerator on the right (refrigerator C). After the second refrigerator on the right receives the ID and right-direction position information of the first refrigerator on the right, it records The system records the IDs and corresponding locations of the two refrigerators, then sends the IDs and corresponding rightward location information of the first and second refrigerators on the right to the third refrigerator on the right. (Refrigerator C's IC card now records rightward information: ID3 Right 2 & ID4 Right 1.) Similarly, the information of the third refrigerator on the right (refrigerator B) is combined and recorded, and sent to the fourth refrigerator on the right (the leftmost refrigerator / refrigerator A). Refrigerator B's IC card now records rightward information: ID2 Right 3, ID3 Right 2 & ID4 Right 1, while refrigerator A's IC card records rightward information: ID1 Right 4 & ID2 Right 3 & ID3 Right 2 & ID4 Right 1. The relative positions of the individual refrigerators can be inferred based on the IC card records of refrigerator A.

[0093] Furthermore, the position recognition instruction is used to realize Figure 9 The left-direction information transmission and the right-direction information transmission shown in the figure control each single refrigerator to send the stored refrigerator ID and location information to all other connected single refrigerators, and store the refrigerator ID and location information received from other single refrigerators. After a period of data interaction, each single refrigerator can obtain the following information: Figure 9As shown, the IC chip (Integrated Circuit Chip) of each single refrigerator (such as IC1 of refrigerator A, IC2 of refrigerator B, IC3 of refrigerator C, and IC4 of refrigerator D) records each ID and its location information. It is understandable that the location identification instruction can be input by the user through a button set on the refrigerator body, the refrigerator display, or a mobile terminal such as a mobile phone. It is understandable that the number of main refrigerators can be 1, 2, 3, or 4, etc., which can be set according to actual conditions.

[0094] Furthermore, the client APP can identify the relative positions of individual refrigerators by obtaining the refrigerator ID and location information recorded by any individual refrigerator.

[0095] In an optional embodiment, the left interface includes a left sending interface and a left receiving interface, and the right interface includes a right sending interface and a right receiving interface. The left sending interface and the right sending interface are used to send the refrigerator ID stored in the single refrigerator to which the interface belongs and the location information associated with the refrigerator ID; the left receiving interface and the right receiving interface are used to receive the refrigerator ID stored in the adjacent single refrigerator and the location information associated with the refrigerator ID. Figure 6 As shown, each single refrigerator has a right interface (RX1 and TX1) and a left interface (RX2 and TX2). RX1 is the interface for receiving information from the right side, TX1 is the interface for sending information to the right side, RX2 is the interface for receiving information from the left side, and TX2 is the interface for sending information to the left side. Furthermore, the cabinet interface can be used to determine whether the single refrigerator is the leftmost refrigerator or the rightmost refrigerator. For example, see Figure 10 and Figure 11 , Figure 10 This is a flowchart of identifying the leftmost refrigerator provided by an embodiment of the present invention. Figure 11 This is a flowchart for identifying the rightmost refrigerator provided by an embodiment of the present invention. When RX2 of a single refrigerator does not receive information sent by other refrigerators and RX1 receives information sent by other refrigerators, then the single refrigerator is the leftmost refrigerator in the spliced ​​refrigerator; when RX2 of a single refrigerator does not receive information sent by other refrigerators and RX1 does not receive information sent by other refrigerators, then the single refrigerator is an independent refrigerator; when RX1 of a single refrigerator does not receive information sent by other refrigerators and RX2 receives information sent by other refrigerators (such as ID and location information), then the single refrigerator is the rightmost refrigerator in the spliced ​​refrigerator.

[0096] In an optional embodiment, the controller is further used to: send refrigerator information of the spliced ​​refrigerator to the client; wherein the refrigerator information includes food information of each of the individual refrigerators and the relative positions between the individual refrigerators.

[0097] Specifically, the food information includes food information itself (such as beef, apple, etc.) and food storage location information (such as beef is stored in the freezer of refrigerator A), which is stored in the food information library of the client.

[0098] Specifically, to facilitate user management of refrigerators, see Figure 12 , Figure 12 : This is a schematic diagram of the structure of the refrigerator management system provided by an embodiment of the present invention. The spliced ​​refrigerator 10 establishes a data connection with the client 20 through the router 30 or the cloud server 40. When the spliced ​​refrigerator 10 and the client 20 communicate through the router 30, the spliced ​​refrigerator 10 and the client 20 are relatively close to each other, and the user can view the operation status or food storage status of the spliced ​​refrigerator placed in the kitchen in the living room or room. When the spliced ​​refrigerator 10 and the client 20 communicate through the cloud server 40, the spliced ​​refrigerator 10 and the client 20 are relatively far apart, and the user can interact with the spliced ​​refrigerator 10 through the APP installed in the client 20, and can also realize remote control of the spliced ​​refrigerator 10.

[0099] For example, see Figure 13 and Figure 14 , Figure 13 This is a food storage information registration flow chart provided by an embodiment of the present invention. Figure 14 This is a food information query and modification flow chart provided by an embodiment of the present invention. The specific process of food storage information is: open the client APP, in the APP, select a refrigerator in the connected refrigerator and open the food storage compartment door, select the food picture and enter information such as weight and shelf life, and drag the food picture to the food storage area, such as the first shelf of the refrigerator and the second drawer of the freezer; the specific process of food information query and modification is: open the client APP, in the APP, enter food information, such as beef, execute food query, and the APP displays the refrigerator where the food is located, storage area, weight, and shelf life information.

[0100] Specifically, there is at least one single refrigerator in the spliced ​​refrigerator that can be connected to the Internet. When all single refrigerators have the networking function, each single refrigerator can upload its own food information, etc. to the client through the network, or specify a single refrigerator to receive food information, etc. from other single refrigerators and upload it to the client. The specific networking method of the spliced ​​refrigerator is not limited here.

[0101] In an optional embodiment, the client is used to: determine the single refrigerator where the target ingredient is located in response to a user's ingredient search instruction; and determine the position of the single refrigerator where the target ingredient is located based on the relative positions between the single refrigerators.

[0102] Specifically, users can enter a food search command on the client, which parses the command to identify the target food. It then searches the food information database to locate the refrigerator where the target food is located. Based on the relative positions of the refrigerators, the location of the refrigerator where the target food is located is determined and displayed on the client. Users can then directly take the food from the corresponding refrigerator based on the information displayed on the client, making food storage and retrieval more convenient and improving the user experience.

[0103] In an optional embodiment, the controller is further configured to:

[0104] Receive and analyze user control instructions sent by the client to determine the target refrigerator and target operating mode;

[0105] The target single refrigerator is controlled to operate in the target operating mode and a display screen of the target single refrigerator is controlled to present a preset operating state.

[0106] For example, a user can set the temperature of a refrigerator's refrigerator or freezer compartment on the app. The app then sends the user-set information to the connected refrigerator, which then sets the temperature of the corresponding compartment in the corresponding refrigerator based on the information received from the client. Furthermore, the display of the corresponding refrigerator flashes to let the user know which refrigerator is currently being set. Alternatively, the user can drag refrigerators on the app to arrange them according to their actual relative positions for easier management.

[0107] Compared with the prior art, the spliced ​​refrigerator disclosed in the embodiment of the present invention includes at least two single refrigerators spliced ​​side by side through a cabinet interface; the cabinet interface is provided on the single refrigerator, including a left interface and a right interface; for the main refrigerator, the first slave setting side interface that controls the other single refrigerators sends the stored refrigerator ID and the location information associated with the refrigerator ID; the second slave setting side interface that controls the other single refrigerators receives the refrigerator ID and the location information associated with the refrigerator ID and merges it with the refrigerator ID and location information of its own single refrigerator for storage; wherein the first slave setting side interface is the cabinet interface close to the main refrigerator, and the second slave setting side interface is the cabinet interface far away from the main refrigerator; wherein the main refrigerator is one of the single refrigerators; the setting side interface that controls the main refrigerator receives the refrigerator ID and the location information associated with the refrigerator ID of all other single refrigerators as a location parameter; and determines the relative position between the single refrigerators according to the location parameter. It can be seen from this that the embodiment of the present invention can splice each single refrigerator side by side to form a spliced ​​refrigerator through the cabinet interface, and obtain the refrigerator ID and location information of the adjacent refrigerators through the cabinet interface to determine the relative position between each single refrigerator, which is beneficial to refrigerator management.
