1A to 1C, some embodiments of the present disclosure provide a refrigerator, wherein the refrigerator 1000 includes a box body 100 and a door body 200 defining a storage space. A component storage cavity and at least one storage chamber are provided in the box body 100. The component storage cavity is configured to place various components in the refrigerator, such as a compressor, etc. The storage chamber is configured to store food, etc. The storage chamber can be divided into a refrigerating chamber, a freezing chamber, a variable temperature chamber, a vacuum chamber, etc. according to different uses. The door body 200 is configured to open or close the storage chamber. One or more door bodies 200 are provided at the opening of each storage chamber. For example, two storage chambers are provided in the box body 100, and the storage chamber at the upper part of the box body 100 is a refrigerating chamber 101, and the refrigerating chamber 101 is provided with two door bodies 200. The storage chamber at the lower part of the box body 100 is a freezing chamber 102, and a door body 200 is provided at the opening of the freezing chamber 102.

The door body 200 can be rotated to open, or connected to the drawer box in the storage room, and opened and closed by pushing and pulling. The door body 200 includes a door body shell 210 located outside the box body 100, a door body inner liner 220 located inside 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 inner liner 220, the upper end cover 230, and the lower end cover 240. The insulation layer can be filled with foam material.

In some embodiments, a door seal is installed at the opening of the storage chamber so that the door body 200 is in close contact with the opening of the storage chamber when the door body 200 is closed.

2 , the refrigerator 1000 further includes a refrigeration system configured to refrigerate the storage room in the cabinet 100. The refrigeration system includes a compressor 1, a condenser 2, and an evaporator 6. The outlet of the compressor 1 is connected to the inlet of the condenser 2, and the inlet of the compressor 1 is connected to the outlet of the evaporator 6. The compressor 1 is configured to compress the refrigerant and provide power for the refrigerant circulation.

In some embodiments, the refrigeration system further includes a filter 4, a pressure reducer 5 and a gas-liquid separator 7. The inlet of the filter 4 is connected to the outlet of the condenser 2, and the outlet of the filter 4 is connected to the inlet of the evaporator 6. The pressure reducer 5 is arranged on the pipeline between the outlet of the filter 4 and the inlet of the evaporator 6. The filter 4 is configured to filter debris in the refrigerant, such as metal chips, dust, etc., to prevent the debris from clogging the pressure reducer 5 or damaging the compressor 1. The filter 4 can be a drying filter. The gas-liquid separator 7 is arranged on the pipeline between the inlet of the compressor 1 and the outlet of the evaporator 6.

In some embodiments, the refrigeration system further includes an anti-condensation pipe 3, which is disposed at the connection between the cabinet 100 and the door 200 and is connected to the condensers 2 on both sides of the cabinet 100. The anti-condensation pipe 3 is configured to increase the temperature of the connection to prevent the water vapor outside the cabinet 100 from condensing into water droplets when it encounters cold at the connection. A liquid reservoir is also disposed between the evaporator 6 and the compressor 1 to store liquid refrigerant.

In some embodiments, the working process of the refrigeration system includes a compression process, a condensation process, a throttling process and an evaporation process. First, the power line of the refrigerator 1000 is connected to power on the refrigerator 1000. If the temperature of the storage room in the refrigerator 1000 is outside the preset temperature range, the contact of the thermostat is connected and the compressor 1 starts to work.

For example, the compression process is as follows: the compressor 1 starts working, the low-temperature, low-pressure refrigerant is sucked into the compressor 1 , is compressed into a high-temperature, high-pressure superheated gas in the cylinder of the compressor 1 , and is 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 steam at room temperature and high pressure, and is further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature. The pressure of the refrigerant remains almost unchanged during the entire condensation process.

The throttling process is as follows: the condensed refrigerant saturated liquid passes through the filter 4 to remove moisture and impurities, then flows into the pressure reducer 5, and is throttled and depressurized by the pressure reducer 5 to become 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 6 and the gas around the evaporator 6, but also turns the refrigerant into a low-temperature and low-pressure gas.

The refrigerant from the evaporator 6 passes through the gas-liquid separator 7 and then returns to the compressor 1. By repeating the above working process, the heat in the refrigerator 1000 can be transferred to the air outside the box, thereby achieving the purpose of refrigeration.

1A , the refrigerator 1000 further includes a display device 40, which is configured to display information such as the temperature of the storage chamber, the type of food, and the weight of food. The display device 40 is also configured to accept a control instruction input by a user, such as a user setting the temperature of the storage chamber. The display device 40 may be a display screen.

At present, more and more refrigerators 1000 have networking functions. For example, refrigerator 1000 has a built-in wireless fidelity (WiFi) component, which connects to the Internet through a networking method combining a router and a wireless access point (WAP). Furthermore, refrigerator 1000 connects to a cloud server through the Internet, and binds the cloud server to an application (APP) on a mobile terminal to achieve functions such as remote control, status monitoring, and food management of refrigerator 1000. During daily use, refrigerator 1000 may experience power outages, etc., resulting in abnormal networking status. After refrigerator 1000 is powered off and then powered on again, it needs to reconnect to the Internet to meet the user's remote management needs for refrigerator 1000.

Referring to FIG. 3A , a networking method in which a router and a wireless access point are combined is described. The topological structure of the networking method includes a wireless access point 301, an access controller (AC) 302, a Power Over Ethernet (POE) switch 303, a router 304, and the Internet 305. The wireless access point 301 is configured to be connected to a networked device to transmit data with the networked device. The access controller 302 is configured to manage each wireless access point 301. The POE switch 303 is configured to power each wireless access point 301 through a network cable. The router 304 is configured to send a target Internet Protocol Address (IP address) to the networked device to achieve connection (i.e., networking) between the networked device and the Internet 305, as well as information transmission between each networked device in the local area network.

This networking method is widely used in large-sized households (eg, more than 120 square meters), enterprises, shopping malls, etc. Compared with the wireless mesh networking method in the related art, the networking method combining the router 304 and the wireless access point 301 has the following advantages.

First, the wireless access point 301 uses a built-in antenna, has a simple appearance, and has a good signal. Second, since the access controller 302 can uniformly manage all wireless access points 301, the networking mode of combining the router 304 with the wireless access point 301 is convenient for the user to manage each wireless access point 301. For example, the user sets a parameter through the access controller 302, and the access controller 302 uniformly sends the parameter to all wireless access points 301.

Furthermore, in the networking mode in which the router 304 and the wireless access point 301 are combined, many devices can be connected to the network, the network coverage is wide, and seamless roaming and automatic switching of the wireless access point 301 are supported, and the switching time is short. The networking mode in which the router 304 and the wireless access point 301 are combined also supports multiple service set identifiers (Service Set Identifier, SSID), and can distinguish whether the SSID is used internally or externally. The SSID can be the name of the wireless access point 301. Finally, the networking mode in which the router 304 and the wireless access point 301 are combined can also support functions such as authentication for Internet access, channel optimization, and load balancing.

In some embodiments, referring to Figures 1A, 3A and 3B, the refrigerator 1000 further includes a first communication component 10. The first communication component 10 is disposed on the housing 100 and is configured to be connected to the router 304 through the wireless access point 301 to achieve connection with the cloud server 80. For example, the first communication component 10 includes a WiFi component.

It should be noted that the cloud server 80 is configured to provide data storage and cloud computing services to the first communication component 10. The refrigerator 1000 can be further connected to the cloud server 80 after networking, and communicate with the mobile terminal 90, such as a mobile phone or tablet computer, through the cloud server 80.

In some embodiments, a Dynamic Host Configuration Protocol (DHCP) server is configured in the router 304 and is configured to assign a target IP address to a networked device (e.g., the first communication component 10). The networked device can search for the DHCP server by broadcasting to obtain the target IP address.

It is understandable that the router 304 can allocate a target Internet Protocol Address (IP address) to a networked device (e.g., the first communication component 10) in the local area network by starting a DHCP server. The networked device can connect to the router 304 through the target IP address.

It should be noted that the DHCP server can use the DHCP protocol to configure IP addresses, subnet masks, gateways, DNS, etc. for each networked device connected to the wireless access point 301 .

The following describes the process of the first communication component 10 connecting to the Internet through the networking method of combining the router 304 with the wireless access point 301.

3A to 4, first, the first communication component 10 uses the SSID (e.g., the default wireless name of the wireless access point 301) and the password to connect to the wireless access point 301. Then, the first communication component 10 requests the target IP address from the router 304 through the DHCP server to connect to the router 304 and achieve connection with the Internet 305. The first communication component 10 is then connected to the cloud server 80 through the Internet 305 and is bound to the APP of the mobile terminal 90.

It is understandable that the wireless access point 301 can be used as an independent device, or can be integrated with the router 304 and used as a component of the router 304 .

In the case of using a router 304 in which the router 304 and the wireless access point 301 are integrated, since the power off and power on of the router 304 and the wireless access point 301 occur almost simultaneously, the refrigerator 1000 can smoothly reconnect to the network in this case.

However, when the router 304 and the wireless access point 301 are separated, the router 304 and the wireless access point 301 may be powered separately. At this time, there is a difference in the power-off and power-on time of the router 304 and the wireless access point 301. In this case, the refrigerator 1000 may not be able to reconnect to the network.

For example, when the router 304 and the wireless access point 301 are separated, if the following two situations occur, the first communication component 10 may be unable to reconnect to the network.

Situation 1: After the router 304, the wireless access point 301, and the first communication component 10 are powered on, only the router 304 is powered off. In this case, only the router 304 needs to be powered on.

Case 2: After the router 304, the wireless access point 301, and the first communication component 10 are powered off, the wireless access point 301 and the first communication component 10 are powered on first, but the router 304 is powered on later than the wireless access point 301 and the first communication component 10 due to a late power-on time or a long startup time. At this time, the router 304 starts to work after the wireless access point 301 has been working for a period of time.

From the above two situations, it can be seen that the reason why the first communication component 10 cannot reconnect to the Internet 305 and the cloud server 80 is that the wireless access point 301 and the router 304 are not turned on synchronously. At this time, the first communication component 10 first connects to the wireless access point 301. Since the router 304 is not turned on at this time, the first communication component 10 cannot obtain the target IP address. Afterwards, even if the router 304 is powered on again, the first communication component 10 may not be able to connect to the network.

For example, in case 1, when the router 304 is powered off and the wireless access point 301 remains powered on, the first communication component 10 can connect to the wireless access point 301 through the SSID and password. However, since the router 304 is not started at this time, the first communication component 10 cannot obtain the target IP address assigned by the router 304.

In some embodiments, since the first communication component 10 will be turned off after the preset reconnection time has expired, even if the router 304 is powered on again, the first communication component 10 may still fail to connect to the Internet.

To solve the above problems, some embodiments of the present disclosure provide a refrigerator 1000. After the refrigerator 1000 is powered on again, it first connects to the wireless access point 301 through the connection information before the power failure. If it cannot connect to the wireless access point 301 at this time, it repeatedly tries to connect to the wireless access point 301 within a first preset time until the connection is successful. After that, it repeatedly tries to obtain the target IP address assigned by the router 304 within a preset number of requests. If the connection to the router 304 is successful within the preset waiting time, the target IP address is requested from the router 304 through the DHCP server, and the cloud server 80 is connected according to the target IP address.

It is understandable that, since the first communication component 10 will continuously try to request the target IP address from the router 304, even if the first communication component 10 exceeds the reconnection time and the router 304 is successfully started, the network can still be successfully connected.

In some embodiments, the refrigerator 1000 further includes a controller 60. The controller 60 may be a chip or a processor. For example, the processor may be a general-purpose central processing unit (CPU), a microprocessor, or an application specific integrated circuit (ASIC). Alternatively, the controller 60 may be a programmable device, including a complex programmable logic device (CPLD), an erasable programmable logic device (EPLD), or a field programmable gate array (FPGA). The chip may be an integrated circuit (IC).

It should be noted that within the preset time, even if the router 304 is powered off and restarted, the same target IP address will still be assigned to the same networked device. In case 1, only the router 304 is powered off and restarted. Since the target IP address of the first communication component 10 may not change at this time, you can try to connect to the router 304 using the target IP address obtained before the power failure.

In some embodiments, the controller 60 is configured to: if it is determined that the first communication component 10 is not connected to the cloud server 80, start the service of connecting to the cloud server 80, so as to reconnect to the cloud server 80 according to the target IP address obtained before the first communication component 10 goes offline. If the first communication component 10 cannot connect to the cloud server 80, control the first communication component 10 to restart, so that the first communication component 10 enters the initialization operation.

For example, if it is determined that the first communication component 10 is not connected to the cloud server 80, the service of connecting to the cloud server 80 is started. At this time, the wireless access point 301 may be turned on, but the router 304 is still not turned on, such as the above-mentioned situation 1 and situation 2. At this time, the first communication component 10 first attempts to establish a connection with the wireless access point 301. However, in this case, since the first communication component 10 cannot obtain a new target IP address from the router 304, it still uses the target IP address obtained from the router 304 before going offline to try to connect to the wireless access point 301.

If the first communication component 10 is reconnected to the wireless access point 301 and further connected to the cloud server 80, the first communication component 10 can report the network status at a preset interval. For example, the interval is 5 minutes. At this time, the APP of the mobile terminal 90 can reconnect to the first communication component 10 based on the information of the bound first communication component 10, so that the user can remotely control the refrigerator 1000 through the APP. If the first communication component 10 cannot connect to the wireless access point 301 using the target IP address obtained from the router 304 before going offline, the control first communication component 10 can be used to connect to the wireless access point 301. A communication component 10 is restarted so that the first communication component 10 enters the initialization operation.

In some embodiments, for case 1 and case 2, the controller 60 is further configured to: in response to the initialization operation of the first communication component 10, restore the IP address of the first communication component 10 to a preset default IP address, and reconnect to the wireless access point 301 according to the connection information of the wireless access point 301 connected before power failure. After the first communication component 10 is connected to the wireless access point 301, request the target IP address from the router 304. After obtaining the target IP address, control the first communication component 10 to connect to the cloud server 80 according to the target IP address.

For example, the first communication component 10 performs an initialization operation after restarting. Since the target IP address obtained from the router 304 before going offline cannot connect to the wireless access point 301, the IP address of the first communication component 10 is restored to a preset default IP address. After the above initialization operation is completed, the first communication component 10 reconnects to the wireless access point 301 using the connection information of the wireless access point 301 before restarting.

It should be noted that the preset default IP address may be stored in the first communication component 10 , and the connection information may include the SSID and password of the wireless access point 301 .

If it is determined that the first communication component 10 is connected to the wireless access point 301, it means that the router 304 may be powered on at this time. After the first communication component 10 requests the target IP address from the router 304 through the DHCP server, the router 304 can return the target IP address. After obtaining the target IP address, the first communication component 10 performs the action of connecting to the cloud server 80.

In some embodiments of the present disclosure, after the first communication component 10 is restarted, since the router 304 is not started, the first communication component 10 cannot obtain the target IP address assigned by the router 304. At this time, the controller 60 first uses the default IP address to connect to the wireless access point 301. Then, when the router 304 is powered on again, the target IP address is requested from the router 304 through the DHCP server, and the cloud server 80 is reconnected according to the target IP address. In this process, since the target IP address is requested from the router 304, even if the router 304 is powered on after the first communication component 10 exceeds the reconnection time, the first communication component 10 can successfully connect to the network.

In some embodiments, the controller 60 is further configured to: if the wireless access point 301 cannot be connected according to the connection information of the wireless access point 301 connected before the power failure, then the wireless access point 301 is connected once according to the connection information at every first time interval within the preset time until the connection is successful. If the connection is still not successful after the preset time, the wireless access point 301 is connected once according to the connection information at every second time interval until the connection is successful.

It should be noted that the first duration is shorter than the second duration. The preset time may be 5 minutes, the first duration may be 10 seconds, and the second duration may be 1 minute.

For example, if the wireless access point 301 cannot be connected according to the connection information, the wireless access point 301 is connected once every 10 seconds within 5 minutes, and once every 1 minute after 5 minutes.

It should be noted that the values of the preset time, the first duration and the second duration are only examples. In actual applications, the preset time, the first duration and the second duration may also be values such as 10 minutes, 5 seconds, 30 seconds, etc., respectively, and the present disclosure does not limit this.

In some embodiments, the controller 60 is further configured to: if the target IP address is not obtained, continue to request the target IP address from the router 304, and record the number of requests. If it is determined that the number of requests is greater than the preset request number threshold, and the target IP address is not obtained, the IP address of the first communication component 10 is controlled to be restored to the default IP address, and a prompt message is issued to remind the user to check the router 304, and the waiting time is recorded. After the waiting time is greater than the preset timeout time, the first communication component 10 is controlled to restart.

For example, the preset request number threshold is 4 times and the preset timeout period is 10 minutes.

The first communication component 10 can use the DHCP server to request the target IP address from the router 304. If the target IP address is not requested, the target IP address is continuously requested from the target router 304, and the number of requests is recorded. If the number of requests is greater than the preset request number threshold, that is, the target IP address is still not requested at the fifth request, an error code indicating that the network is not connected is displayed on the display device 40 of the refrigerator 1000, and a prompt message is sent to the APP to remind the user to check the router 304.

For example, the reason for the failure to connect to the Internet at this time may be that the user only powered on the wireless access point 301, while the router 304 has not been powered on. Then, after the user powers on the router 304, the first communication component 10 can obtain the target IP address. The refrigerator 1000 starts recording the waiting time after displaying the error code of not connecting to the Internet. If the waiting time is greater than 10 minutes, the first communication component 10 is controlled to restart and re-execute the initialization operation to perform the steps of connecting to the wireless access point 301 and making a DHCP request.

In some embodiments of the present disclosure, since the router 304 is turned on later than the first communication component 10, that is, after the first communication component 10 is restarted, the router 304 is still not turned on, so the first communication component 10 cannot obtain the target IP address assigned by the router 304. At this time, the wireless access point 301 is first connected using the default IP address, and then after the router 304 is successfully started, the target IP address is requested from the router 304 through the DHCP server, and the cloud server 80 is connected according to the target IP address. In this process, since the first communication component 10 requests the target IP address from the router 304, so even if the first communication component 10 exceeds the reconnection time and the router 304 is successfully started, the network can still be successfully connected.

5 , some embodiments of the present disclosure further provide a method for controlling a refrigerator 1000 , the method comprising steps S1 to S3 .

Further, referring to FIG. 10 , for situation 1, the method may include S101 to S37 .

Referring to Figure 11, for situation 2, the method may include S11 to S37. If the router 304, the wireless access point 301 and the refrigerator 1000 are all powered off and then powered on, the first communication component 10 performs an initialization operation after restarting. Under the initialization operation, the first communication component 10 uses the SSID and password of the wireless access point 301 bound before power failure to connect to the wireless access point 301, and obtains the target IP address from the DHCP server of the router 304 and connects to the cloud server 80. After failing to obtain the target IP address, the IP address of the first communication component 10 is restored to the default IP address. After waiting for 10 minutes, the first communication component 10 is restarted to re-execute the initialization operation, and retry to connect to the wireless access point 301 and obtain the target IP address.

It should be noted that, compared with situation one, in situation two, since the router 304 will assign a new target IP address to the first communication component 10, the controller 60 does not need to execute the above S101 to S104, but executes S11 to S37 after the refrigerator 1000 is powered on.

The refrigerator 1000 and the control method of the refrigerator 1000 provided in some embodiments of the present disclosure are configured to respond to the initialization of the first communication component 10. After the power-off operation, the IP address of the first communication component 10 is restored to the preset default IP address, and the wireless access point 301 is connected according to the connection information of the wireless access point 301 before the power failure. After the first communication component 10 is connected to the wireless access point 301, the router 304 is requested for the target IP address, and the first communication component 10 is controlled to connect to the cloud server 80 according to the target IP address. In this way, the problem that the device does not reconnect to the cloud server 80 under abnormal circumstances is solved. In addition, the abnormal situation prompt is added to guide the user to check and eliminate network problems.

In some embodiments, the first communication component 10 of the refrigerator 1000 is disposed on the box 100 and is configured to be coupled to the cloud server 80 to achieve network communication of the refrigerator 1000. For example, the first communication component 10 includes a WiFi component. In this way, the APP of the mobile terminal 90 can establish a connection with the refrigerator 1000 through the first communication component 10, so that the user can obtain information such as the storage room temperature, food type, and food weight of the refrigerator 1000 by logging into the APP, thereby achieving remote control of the refrigerator 1000.

When the refrigerator 1000 is used for the first time, the refrigerator 1000 needs to be connected to the network and the refrigerator 1000 needs to be bound to the APP of the mobile terminal 90. For example, the user can input the SSID and password of the wireless network through the display device 40 or the mobile terminal 90 to connect the refrigerator 1000 to the network. Of course, the SSID of the wireless network can also be obtained by scanning. After connecting to the network, the refrigerator 1000 can communicate with the mobile terminal 90 through the first communication component 10.

Afterwards, the user can bind the refrigerator 1000 to the APP of the mobile terminal 90 through the mobile terminal 90. First, the user can select "Add device" through the APP of the mobile terminal 90 to scan and obtain the identification information of the refrigerator 1000. The mobile terminal 90 stores the identification information of the current APP (or its own device code) and the identification information of the refrigerator 1000 to the cloud server 80 to bind with the refrigerator 1000. Since the mobile terminal 90 needs to obtain the refrigerator 1000 through the first communication component 10. Therefore, the mobile terminal 90 also needs to obtain the identification information of the first communication component 10 and upload it to the cloud server 80 to bind with the first communication component 10.

It should be noted that the identification information of the APP may be a user's login name (eg, phone number), and the same login name may be used to log in to the APPs of multiple mobile terminals 90. At this time, the cloud server 80 may also store the device codes of multiple mobile terminals 90.

In some embodiments, a corresponding first identification code is preset in the first communication component 10, and the first identification code includes identification information of the first communication component 10. For example, the first identification code is an identity identification code (Identity, ID) of a WiFi component. The refrigerator 1000 includes a second identification code, and the second identification code includes identification information of the refrigerator 1000. For example, the second identification code is a product serial number (Serial Number, SN) of the refrigerator 1000. The second identification code can be pasted on the outside of the box 100.

12 , the outside of the box 100 is provided with a whole machine barcode 501, which is configured to display the second identification code of the refrigerator 1000. The outside of the box 100 is also provided with a label 502, which is configured to display the first identification code of the first communication component 10.

In some embodiments, the APP of the mobile terminal 90 can achieve binding with the refrigerator 1000 by acquiring the first identification code and the second identification code. After the binding is successful, the APP can also associate the first identification code with the second identification code, and bind the association relationship with the login name of the current APP and upload it to the cloud server 80 for storage.

For example, the user first scans the label 502 through the APP to obtain the first identification code of the first communication component 10, such as the ID of the WiFi component. To avoid subsequent binding failures, after obtaining the first identification code, the APP obtains the association relationship of the first identification code from the cloud server 80. If it is determined that the first identification code does not have a bound second identification code, the APP will jump to the interface for scanning the second identification code to allow the user to scan the SN code. After the user scans the SN code on the refrigerator 1000, the APP associates the first identification code with the second identification code, binds the association relationship with the login name of the current APP, and uploads it to the cloud server 80, so that the binding with the refrigerator 1000 can be completed.

In some embodiments, in order to reduce the operation steps of binding the APP with the refrigerator 1000, the ID and SN code of the WiFi component are pre-associated during the production process of the refrigerator 1000. In this way, during the binding process, after obtaining one of the first identification code and the second identification code, the APP can obtain the association relationship of the first identification code or the second identification code from the cloud server 80 to complete the binding with the refrigerator 1000. For example, the APP first obtains the ID of the WiFi component, and then obtains the SN code corresponding to the ID of the WiFi component from the cloud server 80, so as to complete the binding of the mobile terminal 90 with the refrigerator 1000.

It should be noted that after obtaining the first identification code, the APP can establish a connection with the refrigerator 1000 through the first communication component 10 to achieve remote management of the refrigerator 1000. After obtaining the second identification code, the APP can obtain information such as the device type, function information, and instructions for use of the refrigerator 1000.

In some embodiments, during the production process of the refrigerator 1000, the label 502 and the whole machine barcode 501 are scanned by a scanner, an optical character recognition (OCR) device, etc., and the first identification code and the second identification code are uploaded to the cloud server 80 to pre-establish an association between the first identification code and the second identification code.

It can be understood that the first communication component 10 is correspondingly provided with a label 502, for example, the label 502 displays a QR code, and the QR code includes the information of the first identification code stored in the first communication component 10. That is, the information of the first identification code stored in the first communication component 10 is consistent with the QR code information displayed on the label 502.

For example, during the production process of the refrigerator 1000, the first communication component 10 is first assembled in the box body 100. Afterwards, the label 502 corresponding to the first communication component 10 is pasted on the upper end cover 230 of the door body 200, and the whole machine barcode 501 of the refrigerator 1000 is pasted on a preset position on the back of the box body 100.

On the factory production line, scanners are respectively provided at the top and back of the refrigerator 1000. When the refrigerator 1000 moves on the production line, the scanners respectively scan the corresponding label 502 and the whole machine barcode 501, and upload the obtained first identification code and second identification code to the cloud server 80 to associate the first identification code with the second identification code.

It should be noted that at this time, the cloud server 80 only stores the association between the first identification code and the second identification code. Afterwards, if the user performs a binding operation, the user's binding information will be added to the association. For example, after the user's binding operation is completed, the cloud server 80 adds the login name set by the user when logging into the APP to the association, and stores the first identification code, the second identification code of the refrigerator 1000, and the identification information of the APP to complete the binding of the APP and the refrigerator 1000.

It should be noted that the binding information may also be stored in a binding list of the controller 60 or in the mobile terminal 90 .

13 , the refrigerator 1000 further includes a second communication component 20, which is disposed outside the housing 100 and configured to implement network-free communication between the refrigerator 1000 and the mobile terminal 90. For example, the second communication component 20 is a Bluetooth component.

In some embodiments, the controller 60 is further configured to: in response to the Bluetooth connection operation, receive the second identification code obtained by the mobile terminal 90 after scanning the whole machine barcode 501. Send the first identification code preset in the first communication component 10 to the mobile terminal 90, and control the first communication component 10 to enter the network configuration mode, so that the mobile terminal 90 performs the network configuration operation of the refrigerator 1000 and connects the refrigerator 1000 to the network.

It should be noted that, in the network configuration mode, the user can input the SSID and password through the mobile terminal 90 or the display device 40 so that the first communication component 10 can connect to the wireless network and further connect to the cloud server 80 .

It can be understood that the mobile terminal 90 can not only establish a connection with the refrigerator 1000 through the first communication component 10 to achieve remote control of the refrigerator 1000, but also establish a connection with the refrigerator 1000 through the second communication component 20 to achieve short-range (for example, within 20m) communication with the refrigerator 1000.

13, when the user starts the refrigerator 1000 for the first time, the refrigerator 1000 is not connected to the network. At this time, the user needs to perform network configuration operation on the refrigerator 1000 through the mobile terminal 90. The second communication component 20 of the refrigerator 1000 is started, and the user can establish a connection with the second communication component 20 through the mobile terminal 90 to communicate.

Further, the second communication component 20 sends the first identification code to the mobile terminal 90, so that the first communication component 10 enters the network distribution mode, so that the refrigerator 1000 is connected to the network to interact with the cloud server 80. It should be noted that at this time, the APP of the mobile terminal 90 has not yet been bound to the refrigerator 1000.

After establishing a connection between the mobile terminal 90 and the refrigerator 1000, the user scans the whole machine barcode 501 through the APP to obtain the second identification code and store the second identification code. At this time, the mobile terminal 90 completes the acquisition of the first identification code and the second identification code. The APP can obtain the device type, function settings and other information of the refrigerator 1000 according to the second identification code.

Afterwards, the mobile terminal 90 is further configured to send the acquired second identification code to the second communication component 20. After acquiring the second identification code, the refrigerator 1000 can store the second identification code in the controller 60. The controller 60 can be coupled to the first communication component 10 to acquire the first identification code of the first communication component 10.

It should be noted that the association relationship of the first identification code stored in the cloud server 80 may be wrong. For example, the label 502 corresponding to the first communication component 10 is pasted on the wrong refrigerator 1000. At this time, the first identification code preset in the first communication component 10 of the refrigerator 1000 is inconsistent with the first identification code scanned by the label 502 of the refrigerator 1000.

In some embodiments, the controller 60 is further configured to: obtain a first identification code preset in the first communication component 10 and a second identification code corresponding to the refrigerator 1000. After the refrigerator 1000 is connected to the network, the association status of the first identification code is obtained. If it is determined that the first identification code has established an association relationship, the pending authentication code associated with the first identification code is obtained from the cloud server 80, and it is determined whether the pending authentication code is the same as the second identification code. If it is determined that the pending authentication code is not the same as the second identification code, the cloud server 80 is controlled to update the association relationship of the first identification code and perform a binding operation with the mobile terminal 90.

In some embodiments, the controller 60 is also configured to: if it is determined that the pending authentication code is not the same as the second identification code, control the cloud server 80 to release the association between the first identification code and the pending authentication code, establish an association between the first identification code and the second identification code, and perform a binding operation with the mobile terminal 90.

It should be noted that the controller 60 can be coupled to the first communication component 10 to obtain the first identification code preset in the first communication component 10. The second identification code can be obtained by scanning the whole machine barcode 501 through the mobile terminal 90. Of course, in other embodiments, the second identification code can be pre-stored in the controller 60. It can be understood that the whole machine barcode 501 corresponds to the second identification code of the refrigerator 1000.

It is understandable that when the APP is bound to the refrigerator 1000 for the first time, due to the association relationship obtained from the cloud server 80, The code associated with the first identification code may not be the second identification code of the current refrigerator. Therefore, the identification code associated with the first identification code needs to be used as a pending authentication code to confirm whether the pending authentication code is the second identification code corresponding to the current refrigerator 1000.

Referring to FIG. 14 , after the refrigerator 1000 is connected to the network, it can obtain the association relationship of the first identification code from the cloud server 80. It should be noted that in the case where the first identification code preset in the first communication component 10 has an incorrect association relationship, the user can still complete the binding of the mobile terminal 90 and the refrigerator 1000. For example, the first identification code preset in the first communication component 10 is associated with the SN code of another refrigerator 1000. If this SN code has not been bound by the user, the user can still complete the binding of the mobile terminal 90 and the refrigerator 1000, and the user will not find this problem during use.

However, if the SN code has been bound by another user, the APP will prompt an error message, indicating that the ID or SN code of this WiFi component has been used, and please unbind it before trying again. In this case, the binding will be wrong, which will not only affect the use of refrigerator 1000, but also make the user feel that refrigerator 1000 may have been used before, thus causing user complaints and wasting after-sales resources.

Therefore, in some embodiments of the present disclosure, before binding the mobile terminal 90 and the refrigerator 1000, the association status of the first identification code preset in the first communication component 10 is also determined. If an association relationship is established with the first identification code, the pending authentication code associated with the first identification code is obtained from the cloud server 80. If the pending authentication code is different from the second identification code, the cloud server 80 is controlled to update the association relationship of the first identification code, and the user will not notice this process. After the update is completed, the first identification code preset in the first communication component 10 is accurately associated with the second identification code. At this time, if the user performs the binding operation of the refrigerator 1000 and the mobile terminal 90 again, no error prompt will appear.

Referring to Table 1, Table 1 is the correct association relationship between the first identification code and the second identification code provided in some embodiments of the present disclosure. Assume that there are two refrigerators 1000, refrigerator 1000A and refrigerator 1000B. The first communication component 10A is set in refrigerator 1000A, and the first communication component 10B is set in refrigerator 1000B. The first identification code corresponding to the first communication component 10A is W1, the first identification code corresponding to the first communication component 10B is W2, the second identification code corresponding to the refrigerator 1000A is SN1, and the second identification code corresponding to the refrigerator 1000B is SN2.

Table 1 Correct association between the first identification code and the second identification code

For example, the second identification code corresponding to the whole machine barcode 501 of refrigerator 1000A is SN1, and the first identification code built into the first communication component 10A and the first identification code of the label 502 are the same, both are W1. At this time, when refrigerator 1000 is on the production line, the scanner will upload the second identification code SN1 corresponding to the whole machine barcode 501 and the first identification code W1 corresponding to the label 502 to the cloud server 80, and the association relationship stored in the cloud server 80 is "SN1&W1".

During use, the user 1 scans the whole machine barcode 501 through the mobile terminal 90 to obtain the second identification code SN1, and obtains the first identification code W1 preset in the first communication component 10 through the second communication component 20. After confirming that the association relationship "SN1&W1" in the cloud server 80 is correct, the user 1 binds the APP of the mobile terminal 90 to this association relationship to control the refrigerator 1000 through the APP.

For example, the second identification code corresponding to the whole machine barcode 501 of refrigerator 1000B is SN2, and the first identification code built into the first communication component 10B is the same as the first identification code of the label 502, both of which are W2. At this time, when refrigerator 1000 is on the production line, the scanner will upload the second identification code SN2 corresponding to the whole machine barcode 501 and the first identification code W2 corresponding to the label 502 to the cloud server 80, and the association relationship stored in the cloud server 80 is "SN2&W2".

During use, the second user scans the whole machine barcode 501 through the mobile terminal 90 to obtain the second identification code SN2, and obtains the first identification code W2 preset in the first communication component 10 through the second communication component 20. After confirming that the association relationship "SN2&W2" in the cloud server 80 is correct, the second user binds the APP of the mobile terminal 90 to this association relationship to control the refrigerator 1000 through the APP.

Refer to Table 2, which is an erroneous association relationship between the first identification code and the second identification code provided in some embodiments of the present disclosure. Assume that there are three refrigerators 1000, namely refrigerator 1000A, refrigerator 1000B, and refrigerator 1000C. The first communication component 10A, the first communication component 10B, and the first communication component 10C are respectively set in the above three refrigerators 1000. In the case where the whole machine barcode 501 is not pasted incorrectly, but the label 502 is pasted incorrectly, the following erroneous association relationship may occur.

Table 2 Error association relationship between the first identification code and the second identification code

For example, the second identification code corresponding to the whole machine barcode 501 of refrigerator 1000A is SN1, the first identification code preset in the first communication component 10A is W1, and the first identification code corresponding to the label 502 pasted on the box body 100 is W2 (the first identification code of refrigerator 1000B). When refrigerator 1000A moves on the production line, the scanner will upload the second identification code SN1 scanned by the whole machine barcode 501 and the first identification code W2 of the label 502 to the cloud server 80, and the association relationship stored in the cloud server 80 is "SN1&W2".

The second identification code corresponding to the whole machine barcode 501 of refrigerator 1000B is SN2, the first identification code preset in the first communication component 10B is W2, and the first identification code of the label 502 pasted on the box body 100 is W3 (the first identification code of refrigerator 1000C). When refrigerator 1000B moves on the production line, the scanning gun will upload the second identification code SN2 scanned by the whole machine barcode 501 and the first identification code W3 of the label 502 to the cloud server 80, and the association relationship stored in the cloud server 80 is "SN2&W3".

The second identification code corresponding to the whole machine barcode 501 of refrigerator 1000C is SN3, the first identification code preset in the first communication component 10C is W3, and the first identification code of the label 502 pasted on the box body 100 is W1 (the first identification code of refrigerator 1000A). When refrigerator 1000C is on the production line, the scanner will upload the second identification code SN3 scanned by the whole machine barcode 501 and the first identification code W1 of the label 502 to the cloud server 80, and the association relationship stored in the cloud server 80 is "SN3&W1".

For example, first, user one binds refrigerator 1000A. User one scans the whole machine barcode 501 through the APP of mobile terminal 90 to obtain the second identification code SN1, and receives the first identification code W1 sent by the second communication component 20A through the APP. At this time, refrigerator 1000A will search for the current binding relationship of W1. If it is determined that W1 is associated with SN3, and SN3 associated with W1 is not the same as the second identification code SN1 of refrigerator 1000A, refrigerator 1000A will issue an error message, indicating that the first identification code or the second identification code has been used. At this time, refrigerator 1000A cannot be bound to user one's APP.

In some embodiments, the first identification code and the second identification code are not associated, that is, there is no situation in the above Table 2. This situation may occur because the refrigerator 1000 is missed by the scanner when it moves on the production line, resulting in no association being established in the cloud server 80. At this time, the association between the first identification code and the second identification code can be re-established.

In some embodiments, the controller 60 is further configured to:

If it is determined that the first identification code has not been associated, and the second identification code has not been associated, the cloud server 80 is controlled to establish an association between the first identification code and the second identification code, and perform a user binding operation.

If it is determined that the first identification code has not established an association relationship, and the second identification code has established an association relationship with a third identification code other than the first identification code, the cloud server 80 is controlled to release the association relationship between the second identification code and the third identification code to establish an association relationship between the second identification code and the first identification code, and perform a user binding operation.

In some embodiments, taking refrigerator 1000A as an example, if the built-in first identification code W1 has no association in the cloud server 80, but the second identification code SN1 has established an association "SN1&W2". For example, the scanner did not scan the identification code of the refrigerator 1000A, or user 3 who purchased refrigerator 1000C had already released the wrong association "SN3&W1" before user 1 purchased refrigerator 1000A. At this time, the association between SN1 and W2 is released, the association between SN1 and W1 is established, and the binding operation between refrigerator 1000 and the APP of mobile terminal 90 is completed.

In some embodiments, the controller 60 is further configured to: if it is determined that the pending authentication code is not the same as the second identification code, and the second identification code is associated with a third identification code other than the first identification code, then determine whether the association between the first identification code and the pending authentication code is bound.

If it is determined that the association between the first identification code and the pending authentication code is not bound, the cloud server 80 is controlled to release the association between the first identification code and the pending identification code, and to release the association between the second identification code and the third identification code, so as to establish an association between the first identification code and the second identification code, and perform a binding operation with the APP of the mobile terminal 90.

In some embodiments, the controller 60 is also configured to: if the association between the first identification code and the pending authentication code has been bound, control the cloud server 80 to replace the second identification code and the third identification code to establish an association between the first identification code and the second identification code, and establish an association between the third identification code and the pending authentication code, and perform a binding operation with the APP of the mobile terminal 90.

Referring to Table 2, taking refrigerator 1000A as an example, the first identification code of refrigerator 1000A is W1, and the second identification code is SN1. If in cloud server 80, the first identification code W1 has an association relationship "SN3&W1". Since the second identification code of refrigerator 1000A is SN1, which is different from SN3 in this association relationship, it is necessary to further determine whether the second identification code SN1 has established an association relationship. If it is determined that the second identification code SN1 has established an association relationship, If no association is established between the identification code SN1, the association between SN3 and W1 is released, the association between SN1 and W1 is established, and the binding operation with the APP of the mobile terminal 90 is completed.

If it is determined that the second identification code SN1 has established an association, for example, "SN1 and W2", then it is further determined whether the association "SN3&W1" has been bound to the APP of the mobile terminal 90. For example, the association "SN3&W1" is incorrectly bound because the association between the first identification code and the second identification code is not updated in time in the cloud server 80. If the "SN3&W1" association is not bound to the APP of the mobile terminal 90, the association between SN1 and W2 is controlled to be disassociated, the association between SN3 and W1 is controlled to be disassociated, and the association between SN1 and W1 is established. At this time, W2 and SN3 do not establish an association, and then the binding operation with the APP of the mobile terminal 90 is completed.

In some embodiments, if it is determined that the association relationship "SN3&W1" has been bound to the APP of the mobile terminal 90, the binding relationship between W1 and W2 is replaced, that is, it becomes "SN1&W1, "W2&SN3". At this time, after the user successfully binds the refrigerator 1000 to the APP of the mobile terminal 90, the association relationship in the cloud server 80 can also be replaced.

It is understandable that if the relationship between SN1 and W1 is established and the relationship between W1 and SN3 is released at this time, the user currently bound under the association relationship between SN3 and W1 will also be unbound. In this way, by exchanging the second identification code, the wrong binding relationship stored in the cloud server 80 can be corrected, and the relationship established by the bound users can be guaranteed to be correct, avoiding affecting the previously bound users.

It should be noted that the control method of the refrigerator 1000 can be executed by the controller 60 of the refrigerator 1000, and can also be executed by the APP of the mobile terminal 90.

For example, when the controller 60 executes the above S100 to S400, when the user starts the refrigerator 1000 for the first time, the refrigerator 1000 is not connected to the network. At this time, the second communication component 20 in the refrigerator 1000 is started, and the user can connect to the second communication component 20 through the mobile terminal 90 to communicate with the refrigerator 1000. The user scans the whole machine barcode 501 through the APP of the mobile terminal 90 to obtain the second identification code. At this time, the device type and function of the refrigerator 1000 can be obtained according to the second identification code. Then the user sends the scanned whole machine barcode 501 to the refrigerator 1000 through the second communication component 20, and the second communication component 20 sends the first identification code preset in the first communication component 10 to the mobile terminal 90, so that the device enters the network distribution mode, so that the refrigerator 1000 is connected to the network and exchanges information with the cloud server 80, but at this time the user APP has not yet been bound to the refrigerator 1000.

For example, when the APP of the mobile terminal 90 executes the above S100 to S400, the APP does not need to send the scanned whole machine barcode 501 to the refrigerator 1000 through the second communication component 20 when executing the above S100 to S400.

In the refrigerator 1000 and the control method of the refrigerator 1000 provided in some embodiments of the present disclosure, when the refrigerator 1000 is bound to the APP of the mobile terminal 90, it is also determined whether there is an association error between the first identification code and the second identification code of the refrigerator 1000 in the cloud server. If there is an incorrect association relationship, an automatic correction is performed to re-associate the first identification code and the corresponding correct second identification code. In this way, when the user needs to bind the refrigerator 1000 through the mobile terminal 90, the binding error prompt is avoided, and the user can solve the above problem through the background without perception.

Those skilled in the art will appreciate that the disclosure scope of the present invention is not limited to the above specific embodiments, and certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
