[0047] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 1 A schematic diagram of the structure of a refrigerator provided by an embodiment of the present invention; Figure 2 A partial schematic diagram of a refrigerator door opening and closing device provided by an embodiment of the present invention; Figure 3 A schematic diagram of connecting a controller of a refrigerator provided by an embodiment of the present invention.

[0049] In a specific embodiment of the present invention, an embodiment of the present invention provides a refrigerator, including: a box body 101, a refrigeration function chamber 102 arranged in the box body 101, a refrigerator door 103, a controller 104, a door opening and closing device 105, a communication device 106, and a living thing detection device 107; the door opening and closing device 105 is used to open and close the refrigerator door 103 under the control of the controller 104; the communication device 106 is connected to the controller 104 and is used to communicate with an external device; the living thing detection device 107 is connected to the controller 104 and is used to detect a living thing signal in the refrigeration function chamber 102 and transmit the living thing signal to the controller 104; the controller 104 is used to send the living thing signal to an external device through the communication device 106 after receiving the living thing signal, and control the door opening and closing device 105 according to the control signal received from the external device.

[0050] Specifically, the door opening and closing device 105 can use a linkage device based on the principle of a relay, and more specifically, can include: a fixed housing connected to the door opening side of the box body 101, a telescopic rod, an electromagnetic drive device, and a return spring; one end of the telescopic rod is connected to the electromagnetic drive device; the electromagnetic drive device is used to drive the telescopic end of the telescopic rod to push the refrigerator door 103; the control end of the electromagnetic drive device is connected to the controller 104; the telescopic end of the telescopic rod points to the refrigerator door 103; when the telescopic rod is extended, the refrigerator door 103 is pushed open; the return spring is used to push the telescopic end back to the fixed housing when the electromagnetic drive device is powered off. In other words, a relay can be used as an electromagnetic drive device to push the extension of the telescopic rod, thereby pushing the refrigerator door 103 to open.

[0051] Furthermore, in order to monitor the living things in the refrigerator, the temperature characteristic of living things can be specifically used for detection. Therefore, in this embodiment, the living thing detection device 107 can be set as an infrared thermometer; the infrared thermometer is set inside the box 101, used to detect the temperature of the object in the refrigeration function chamber 102, and send the object temperature to the controller 104; the controller 104 is used to receive the object temperature; determine whether the object temperature exceeds the preset temperature; if the object temperature exceeds the preset temperature, an alarm signal is issued. Therefore, when a child runs into the refrigerator and the refrigerator door 103 is closed and cannot be opened inside, the infrared thermometer will test that the temperature in the refrigerator exceeds the general temperature, because the temperature of the refrigerator's cold storage room is generally below 10 degrees Celsius, and the temperature of the human body is about 37 degrees Celsius. Therefore, it can be identified whether there are living things such as children in the refrigerator.

[0052] Specifically, when an alarm signal is issued, an alarm reminder message can be sent to the external device; or an audible and visual alarm signal can be sent to remind users around the refrigerator. Of course, the refrigerator should be equipped with a sound reminder device and a light reminder device, such as a buzzer, a flashing LED light, etc.

[0053] In another embodiment of the present invention, the moving property of living things can be used to monitor living things. In this case, the living thing detection device 107 can be set as a camera; the camera is set inside the box 101, and is used to capture the real-time image in the refrigeration function chamber 102, and send the real-time image to the controller 104; the controller 104 is used to compare whether there is a moving object in the refrigeration function chamber 102 using adjacent real-time images; if there is a moving object in the refrigeration function chamber 102, the real-time image is sent to an external device and an alarm signal is issued. In other words, the controller 104 compares the images captured by the camera to determine whether there is a moving object in the refrigerator. If there is a moving object, it can be determined that there is a living thing in the refrigerator.

[0054] When the refrigerator is connected to the network, a communication device 106 linked to the controller 104 can be provided. Specifically, the communication device 106 can be provided to include: a mobile communication module and / or a WiFi module. Specifically, one or a combination of more than one of 2G, 3G, 4G, 5G or WiFi modules can be provided. Of course, in practice, since the communication of the WiFi module depends on the wired network and electricity, situations where the WiFi network cannot be connected may occur in life. Therefore, the mobile communication module can be used preferentially. The communication connection of the mobile communication module is more stable. The refrigerator used in this embodiment has a small amount of data transmission, and the mobile communication module can be used preferentially. Of course, other communication devices 106 can also be used. This embodiment does not limit the specific implementation of the communication device 106.

[0055] On the basis of the above specific implementation, in this embodiment, in order to prevent external devices, such as mobile phones and computers of refrigerator users, from receiving the living thing signal in time, the controller 104 set in the refrigerator can also automatically open the refrigerator door 103 after exceeding a preset time. That is to say, the controller 104 is also used to control the door opening and closing device 105 to open the refrigerator door 103 if the control signal of the external device is not received within the preset time when the living thing signal is sent to the external device through the communication device 106. Of course, while opening the refrigerator door 103, the controller 104 can also control the power of the refrigerator to be disconnected. The controller 104 is connected to the refrigerator power control module, and the power control module is used to control the power on and off of the refrigerator.

[0056] An embodiment of the present invention provides a refrigerator, which detects living things signals in the refrigeration function room and transmits the living things signals to the controller; the controller is used to send the living things signals to an external device through the communication device after receiving the living things signals, and control the door opening and closing device according to the control signal received from the external device. Therefore, the refrigerator provided by the embodiment of the invention can detect living things in the refrigerator and send them to an external device. After the external device receives the living things, it can control the door opening and closing device of the refrigerator to open the refrigerator to avoid possible dangers. The refrigerator with a living things detection function and a high temperature alarm remote control door opening and closing function is safe, improves the space utilization rate of the refrigerator, has low cost, and can be remotely monitored.
