[0035] Combination Figure 1 As shown, an embodiment of the present disclosure provides a combined refrigerator, comprising a first refrigerator 1 and a second refrigerator 2. The first refrigerator 1 and the second refrigerator 2 are both provided with a knock sensor for receiving a vibration signal and a wireless module for networking.

[0036] Specifically, the first refrigerator 1 and the second refrigerator 2 are both provided with a knock sensor for receiving a vibration signal and a wireless module for networking, including: the first refrigerator 1 is provided with a first knock sensor 11 for receiving a vibration signal and a first wireless module 12 for networking. The second refrigerator 2 is provided with a second knock sensor 21 for receiving a vibration signal and a second wireless module 22 for networking.

[0037] By using the combined refrigerator provided in the embodiment of the present disclosure, the first refrigerator 1 and the second refrigerator 2 can be freely matched to form a combined refrigerator to meet the personalized needs of users.

[0038] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling a combined refrigerator, comprising:

[0039] S201, when the first refrigerator and the second refrigerator are successfully networked, the first refrigerator determines whether the first refrigerator is a host refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network.

[0040] S202, when the first refrigerator is the host refrigerator, the first refrigerator determines that the second refrigerator having the largest vibration signal strength among the first refrigerator and all the received refrigerators is hit by the user.

[0041] S203, the first refrigerator sends a knock instruction by the user to the second refrigerator, so that the second refrigerator is controlled to perform a door opening action according to the strength of the vibration signal of the second refrigerator, or the second refrigerator is controlled to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network according to the strength of the vibration signal of the second refrigerator.

[0042] According to the method for controlling a combined refrigerator provided by the embodiment of the present disclosure, after the first refrigerator and the second refrigerator in the combined refrigerator are successfully networked, when multiple refrigerators in the combined refrigerator receive a knocking signal, the first refrigerator is selected as the host refrigerator according to the MAC address, and the data is processed by the host refrigerator. The host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, and determines that the second refrigerator with the largest signal strength is knocked by the user. When the user knocks on the second refrigerator, the vibration signal is only transmitted to other refrigerators, not knocked. This avoids all refrigerator doors being opened due to false triggering, and improves the accuracy of opening and closing refrigerator doors.

[0043] Optionally, the vibration signal includes a voltage signal converted from a mechanical vibration signal by a transducer of the knock sensor. In this way, the amplitude of the voltage signal can directly reflect the mechanical vibration intensity, which is conducive to more intuitively reflecting the situation that the modular refrigerator is knocked by the user.

[0044] Optionally, the first refrigerator determines whether the first refrigerator is a host refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network, including: when the MAC address of the first refrigerator is equal to the minimum value of the MAC addresses of all refrigerators in the combined refrigerator connected to the same network, the first refrigerator determines that the first refrigerator is the host refrigerator. In this way, the refrigerator with the smallest MAC address is selected as the host refrigerator. If there is a refrigerator in the combined refrigerator that is not connected to the same network and has just been connected to the network, it only needs to compare the MAC address with the MAC address of the host refrigerator to quickly obtain the refrigerator with the smallest MAC address, which is conducive to quickly determining the host refrigerator.

[0045] Optionally, the first refrigerator determines that the second refrigerator with the strongest vibration signal among the first refrigerator and all the received refrigerators is knocked by the user, including: the first refrigerator receives the vibration signals and MAC addresses of all refrigerators in the combined refrigerator connected to the same network. The first refrigerator sorts the vibration signal strengths of all refrigerators including the first refrigerator from large to small. The first refrigerator determines that the second refrigerator with the highest order is knocked by the user.

[0046] In this way, when multiple refrigerators in the combined refrigerator receive a knocking signal, the control host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, and determines that the second refrigerator with the largest signal strength is knocked by the user. When the user knocks on the second refrigerator, the vibration signal is only transmitted to other refrigerators, not knocked. This avoids all refrigerator doors being opened due to false triggering, and improves the accuracy of refrigerator door opening and closing.

[0047] Optionally, the first refrigerator receives the vibration signals and MAC addresses of all refrigerators in the combined refrigerator connected to the same network, including: within a time threshold, when any refrigerator in the combined refrigerator connected to the same network receives a set number of vibration signals with an intensity greater than a transmission trigger threshold, the first refrigerator receives the vibration signals and MAC addresses of all refrigerators in the combined refrigerator connected to the same network. The value of the time threshold can be 300ms. The value of the transmission trigger threshold can be 30mV. The value of the set number of times can be 2 times.

[0048] In this way, if any refrigerator in the combined refrigerators connected to the same network receives a vibration signal continuously in a short period of time, it is necessary to send the vibration signals of all refrigerators in the combined refrigerators connected to the same network to the host refrigerator for data processing, and determine the knocked refrigerator according to the strength of the vibration signals of all refrigerators in the combined refrigerators connected to the same network. Since any refrigerator in the combined refrigerators connected to the same network receives a vibration signal, it can trigger the host refrigerator's judgment mechanism for which refrigerator is knocked by the user, thereby improving the sensitivity of opening the refrigerator door. In addition, when any refrigerator is knocked, the vibration signals received by all refrigerators are judged, thereby avoiding false triggering that causes all refrigerator doors to open, and improving the accuracy of refrigerator door opening and closing.

[0049] Optionally, the first refrigerator sends a knocking instruction to the second refrigerator, so that the second refrigerator controls the second refrigerator to perform a door opening action according to the vibration signal strength of the second refrigerator, or controls the first refrigerator to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network according to the vibration signal strength of the second refrigerator, including: the first refrigerator sends a knocking instruction to the second refrigerator, so that when the vibration signal strength of the second refrigerator is greater than or equal to the door opening trigger strength threshold of the second refrigerator, the second refrigerator is controlled to perform the door opening action. Or, the first refrigerator sends a knocking instruction to the second refrigerator, so that when the vibration signal strength of the second refrigerator is less than the door opening trigger strength threshold of the second refrigerator, the first refrigerator is controlled to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network. Specifically, the value of the door opening trigger strength threshold can be 30mV (millivolts). In this way, after the host refrigerator determines that the second refrigerator with the largest signal strength is knocked by the user, it notifies the second refrigerator that it is knocked by the user, so that the second refrigerator determines whether the vibration signal strength meets the door opening trigger mechanism or controls the first refrigerator to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network. This helps to avoid all refrigerator doors being opened due to false triggering, improves the accuracy of opening and closing the refrigerator doors, and if the current vibration signal is small and insufficient to trigger the door opening, timely cleaning can avoid memory waste.

[0050] Optionally, before the first refrigerator determines whether the first refrigerator is the host refrigerator according to the MAC addresses of all refrigerators, it also includes: when the first refrigerator is powered on, the first refrigerator searches for the wireless signal of the second refrigerator. When the strength of the wireless signal of the searched second refrigerator is greater than the connection threshold, the first refrigerator sends the MAC address and connection request to the second refrigerator. When the second refrigerator verifies the MAC address of the first refrigerator, the first refrigerator determines that the first refrigerator and the second refrigerator are successfully networked. In this way, the first refrigerator and the second refrigerator are first networked according to the MAC address, which is conducive to selecting the host refrigerator according to the MAC address more quickly. Thereby avoiding all refrigerator doors being opened due to false triggering and improving the accuracy of refrigerator door opening and closing.

[0051] Optionally, in the case where the first refrigerator is a host refrigerator, it also includes: the first refrigerator determines that the first refrigerator with the largest vibration signal strength among the first refrigerator and all the received refrigerators is knocked by the user. The first refrigerator controls the first refrigerator to perform a door opening action according to the vibration signal strength of the first refrigerator, or controls the first refrigerator to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network. In this way, if the vibration signal strength of the first refrigerator is the largest, it is determined that it is knocked by the user and the knocking force is the largest. Then, according to the relationship between the user's knocking force and the door opening trigger threshold, the first refrigerator is opened or all vibration signals are cleared. Thereby avoiding all refrigerator doors being opened due to false triggering, improving the accuracy of refrigerator door opening and closing, and if the current vibration signal is small and insufficient to trigger the door opening, timely clearing the user avoids memory waste.

[0052] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a combined refrigerator, comprising:

[0053] S301, when the first refrigerator is powered on, the first refrigerator searches for a wireless signal of the second refrigerator.

[0054] S302: When the wireless signal strength of the searched second refrigerator is greater than the connection threshold, the first refrigerator sends a MAC address and a connection request to the second refrigerator.

[0055] S303, when the second refrigerator verifies the MAC address of the first refrigerator, the first refrigerator determines that the first refrigerator and the second refrigerator are successfully networked.

[0056] S304, when the first refrigerator and the second refrigerator are successfully networked, the first refrigerator determines whether the first refrigerator is a host refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network.

[0057] S305, when the first refrigerator is the host refrigerator, the first refrigerator determines that the second refrigerator having the largest vibration signal strength among the first refrigerator and all the received refrigerators is hit by the user.

[0058] S306, the first refrigerator sends a knock instruction by the user to the second refrigerator, so that the second refrigerator is controlled to perform a door opening action according to the strength of the vibration signal of the second refrigerator, or the second refrigerator is controlled to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network according to the strength of the vibration signal of the second refrigerator.

[0059] According to the method for controlling a combined refrigerator provided by the embodiment of the present disclosure, the first refrigerator and the second refrigerator in the combined refrigerator retain the MAC address after the network is successfully established. When multiple refrigerators in the combined refrigerator receive a knocking signal, the first refrigerator is selected as the host refrigerator according to the MAC address, and the data is processed by the host refrigerator. The host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, determines that the second refrigerator with the largest signal strength is knocked by the user, and notifies the second refrigerator that it is knocked by the user, so that the second refrigerator determines whether the vibration signal strength meets the door opening trigger mechanism or controls the first refrigerator to clear the received vibration signal of all refrigerators in the combined refrigerator connected to the same network. This is conducive to avoiding all refrigerator doors being opened due to false triggering, improving the accuracy of refrigerator door opening and closing, and if the current vibration signal is small and insufficient to trigger the door opening, timely clearing the user avoids memory waste.

[0060] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling a combined refrigerator, comprising:

[0061] S401, when the first refrigerator and the second refrigerator are successfully networked, the second refrigerator determines whether the second refrigerator is a slave refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network.

[0062] S402, when the first refrigerator is a master refrigerator and the second refrigerator is a slave refrigerator, the second refrigerator sends the received vibration signal strength to the first refrigerator.

[0063] S403, when the vibration signal strength of the second refrigerator is the strongest among the vibration signals of the first refrigerator and all refrigerators in the combined refrigerator connected to the same network, the second refrigerator receives the knocking instruction sent by the first refrigerator.

[0064] S404, the second refrigerator controls the second refrigerator to open the door according to the strength of the vibration signal of the second refrigerator, or controls the first refrigerator to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network according to the strength of the vibration signal of the second refrigerator.

[0065] The method for controlling a combined refrigerator provided by the embodiment of the present disclosure is adopted. The first refrigerator and the second refrigerator are first networked. After the first refrigerator and the second refrigerator in the combined refrigerator are successfully networked, when multiple refrigerators in the combined refrigerator receive a knocking signal, the first refrigerator is selected as the host refrigerator according to the MAC address, and the data is processed by the host refrigerator. The host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, and determines that the second refrigerator with the largest signal strength is knocked by the user. When the user knocks on the second refrigerator, the vibration signal is only transmitted to other refrigerators, not knocked. This avoids all refrigerator doors being opened due to false triggering, and improves the accuracy of refrigerator door opening and closing.

[0066] Optionally, the second refrigerator determines whether the second refrigerator is a slave refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network, including: when the MAC address of the second refrigerator is greater than the minimum value of the MAC addresses of all refrigerators in the combined refrigerator connected to the same network, the second refrigerator determines that the second refrigerator is a slave refrigerator. The refrigerator with the smallest MAC address is selected as the host refrigerator. If there is a refrigerator in the combined refrigerator that is not connected to the same network and has just been connected to the network, it is only necessary to compare the MAC address with the MAC address of the host refrigerator to quickly obtain the refrigerator with an address other than the smallest MAC address, which is conducive to quickly determining the host refrigerator and the slave refrigerator.

[0067] Optionally, the second refrigerator controls the second refrigerator to perform a door opening action according to the vibration signal strength of the second refrigerator, or controls the first refrigerator to clear the received vibration signals of all refrigerators in the combined refrigerator connected under the same network according to the vibration signal strength of the second refrigerator, including: when the vibration signal strength of the second refrigerator is greater than or equal to the door opening trigger strength threshold of the second refrigerator, the second refrigerator controls the second refrigerator to perform a door opening action. Or, when the vibration signal strength of the second refrigerator is less than the door opening trigger strength threshold of the second refrigerator, the second refrigerator controls the first refrigerator to clear the received vibration signals of all refrigerators in the combined refrigerator connected under the same network.

[0068] In this way, if the vibration signal intensity of the first refrigerator is the largest, it is determined that the user has knocked and the knocking force is the largest. Then, according to the relationship between the user's knocking force and the door opening trigger threshold, the first refrigerator is opened or all vibration signals are cleared. This avoids all refrigerator doors being opened due to false triggering, improves the accuracy of refrigerator door opening and closing, and if the current vibration signal is small and insufficient to trigger the door opening, the user is cleared in time to avoid memory waste.

[0069] Optionally, the second refrigerator controls the first refrigerator to clear the received vibration signals of all refrigerators in the combined refrigerator connected to the same network, including: the second refrigerator sends an application to the first refrigerator to clear the received vibration signals of all refrigerators in the combined refrigerator connected to the same network, so that the first refrigerator clears the received vibration signals of all refrigerators in the combined refrigerator connected to the same network. In this way, if the current vibration signal is small and insufficient to trigger the door opening, the vibration signal is cleared in time to avoid false triggering, thereby avoiding memory waste.

[0070] Optionally, before the second refrigerator determines whether the second refrigerator is the host refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network, the method further includes: the second refrigerator sends a wireless signal to the first refrigerator. When the wireless signal strength of the second refrigerator searched by the first refrigerator is greater than the connection threshold, the second refrigerator receives the MAC address and connection request sent by the first refrigerator. When the second refrigerator verifies the MAC address of the first refrigerator, the second refrigerator determines that the first refrigerator and the second refrigerator are successfully networked.

[0071] In this way, the first refrigerator and the second refrigerator are first networked according to the MAC address, which is conducive to selecting the host refrigerator according to the MAC address more quickly, thereby avoiding all refrigerator doors being opened due to false triggering and improving the accuracy of refrigerator door opening and closing.

[0072] Optionally, the second refrigerator sends the received vibration signal strength to the first refrigerator, including: within the duration threshold, when the vibration signal strength received by any refrigerator in the combined refrigerator connected to the same network for a set number of times is greater than the transmission trigger threshold, the second refrigerator sends the received vibration signal strength to the first refrigerator. Specifically, the value of the duration threshold can be 300ms (milliseconds). The value of the transmission trigger threshold can be 30mV. The value of the set number of times can be 2 times.

[0073] In this way, if the vibration signal intensity of the second refrigerator is the largest, it is determined that the user has knocked and the knocking force is the largest. Then, according to the relationship between the user's knocking force and the door opening trigger threshold, the second refrigerator is opened or the first refrigerator is cleared of all vibration signals. This avoids all refrigerator doors being opened due to false triggering, improves the accuracy of refrigerator door opening and closing, and if the current vibration signal is small and insufficient to trigger the door opening, the user is cleared in time to avoid memory waste.

[0074] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling a combined refrigerator, comprising:

[0075] S501, the second refrigerator sends a wireless signal to the first refrigerator.

[0076] S502: When the wireless signal strength of the second refrigerator searched by the first refrigerator is greater than the connection threshold, the second refrigerator receives the MAC address and connection request sent by the first refrigerator.

[0077] S503, when the second refrigerator verifies the MAC address of the first refrigerator, the second refrigerator determines that the first refrigerator and the second refrigerator are successfully networked.

[0078] S504, when the first refrigerator and the second refrigerator are successfully networked, the second refrigerator determines whether the second refrigerator is a slave refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network.

[0079] S505, when the first refrigerator is a master refrigerator and the second refrigerator is a slave refrigerator, the second refrigerator sends the received vibration signal intensity to the first refrigerator.

[0080] S506, when the vibration signal strength of the second refrigerator is the strongest among the vibration signals of the first refrigerator and all refrigerators in the combined refrigerator connected to the same network, the second refrigerator receives the knocking instruction sent by the first refrigerator.

[0081] S507, the second refrigerator controls the second refrigerator to open the door according to the strength of the vibration signal of the second refrigerator, or controls the first refrigerator to clear the vibration signals received from all refrigerators in the combined refrigerator connected to the same network according to the strength of the vibration signal of the second refrigerator.

[0082] According to the method for controlling a combined refrigerator provided by the embodiment of the present disclosure, the first refrigerator and the second refrigerator in the combined refrigerator both retain the MAC address after the network is successfully established. After the first refrigerator and the second refrigerator in the combined refrigerator are successfully established, when multiple refrigerators in the combined refrigerator receive a knocking signal, the first refrigerator is selected as the host refrigerator according to the MAC address, and the data is processed by the host refrigerator. The host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, and determines that the second refrigerator with the largest signal strength is knocked by the user. When the user knocks on the second refrigerator, the vibration signal is only transmitted to other refrigerators, not knocked. This avoids all refrigerator doors being opened due to false triggering, and improves the accuracy of refrigerator door opening and closing.

[0083] In practical applications, such as Figure 6As shown, S601, when the first refrigerator is powered on, the first refrigerator searches for the wireless signal of the second refrigerator. S602, the second refrigerator sends a wireless signal to the first refrigerator. S603, when the strength of the wireless signal of the searched second refrigerator is greater than the connection threshold, the first refrigerator sends a MAC address and a connection request to the second refrigerator. S604, when the second refrigerator verifies the MAC address of the first refrigerator, the second refrigerator determines that the first refrigerator and the second refrigerator are successfully networked. S605, the second refrigerator sends a message of successful networking to the first refrigerator. S606, the first refrigerator determines that the first refrigerator and the second refrigerator are successfully networked. S607, when the first refrigerator and the second refrigerator are successfully networked, the first refrigerator determines whether the first refrigerator is a host refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network. S608, the second refrigerator determines whether the second refrigerator is a slave refrigerator according to the MAC addresses of all refrigerators in the combined refrigerator connected to the same network. S609, when the first refrigerator is the host refrigerator and the second refrigerator is the slave refrigerator, the second refrigerator sends the received vibration signal strength to the first refrigerator. S610, when the first refrigerator is the host refrigerator, the first refrigerator determines that the second refrigerator having the largest vibration signal strength among the first refrigerator and all the received refrigerators is knocked by the user. S611, the first refrigerator sends a knock instruction to the second refrigerator. S612, the second refrigerator determines whether the vibration signal strength of the second refrigerator is greater than or equal to the door opening trigger strength threshold of the second refrigerator. S613, if so, the second refrigerator controls the second refrigerator to perform the door opening action. S614, if not, the second refrigerator sends a request to the first refrigerator to clear the received vibration signals of all refrigerators in the combined refrigerator connected to the same network. S615, the first refrigerator clears the received vibration signals of all refrigerators in the combined refrigerator connected to the same network.

[0084] According to the method for controlling a combined refrigerator provided by the embodiment of the present disclosure, the first refrigerator and the second refrigerator in the combined refrigerator both retain the MAC address after the network is successfully established. After the first refrigerator and the second refrigerator in the combined refrigerator are successfully established, when multiple refrigerators in the combined refrigerator receive a knocking signal, the first refrigerator is selected as the host refrigerator according to the MAC address, and the data is processed by the host refrigerator. The host refrigerator compares the vibration signal strength of all refrigerators in the combined refrigerator connected to the same network, and determines that the second refrigerator with the largest signal strength is knocked by the user. When the user knocks on the second refrigerator, the vibration signal is only transmitted to other refrigerators, not knocked. This avoids all refrigerator doors being opened due to false triggering, and improves the accuracy of refrigerator door opening and closing.
