[0040] Unless otherwise defined, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more related listed items.

[0041] As Figures 1 to 3As shown, a refrigerator 100 provided in one embodiment of this application includes a freezer inner liner 10, a refrigerator inner liner 20, a connecting pipe 30, and a fan assembly 40. The connecting pipe 30 is disposed between the freezer inner liner 10 and the refrigerator inner liner 20, and is connected and communicates with both the freezer inner liner 10 and the refrigerator inner liner 20. The fan assembly 40 is installed inside the refrigerator inner liner 20 and communicates with the connecting pipe 30. When the fan assembly 40 is working, it can transport air inside the refrigerator inner liner 20 to the freezer inner liner 10 through the connecting pipe 30. In other words, the refrigerator 100 can use the fan assembly 40 to force air from the refrigerator inner liner 20 to the freezer inner liner 10.

[0042] As can be seen from the above, the refrigerator 100 uses the fan assembly 40 to force air from the refrigerator inner liner 20 to the freezer inner liner 10, and realizes air circulation between the refrigerator inner liner 20 and the freezer inner liner 10 to balance the air pressure inside the freezer inner liner 10. In this way, the pressure difference between the freezer inner liner 10 and the outside air can be reduced, thereby reducing the opening force required for the user to open the freezer door (not shown) on the freezer inner liner 10 again, which makes it easier to open the door.

[0043] like Figure 3 As shown, the connecting pipe 30 is I-shaped, and it can be connected and fixed to the refrigerator inner liner 20 and the freezer inner liner 10 using screws, bolts, or other connectors (not shown) to achieve the assembly connection between the connecting pipe 30 and the freezer inner liner 10 and the refrigerator inner liner 20. Here, the connecting pipe 30 is disposed within the foam layer (not shown) between the refrigerator inner liner 20 and the freezer inner liner 10. It can be understood that in other embodiments, the connecting pipe 30 can also be connected and fixed to the refrigerator inner liner 20 and / or the freezer inner liner 10 by welding, which will not be elaborated here.

[0044] like Figure 3 As shown, the fan assembly 40 includes a fan 41 and a controller (not shown). The controller is electrically connected to the fan 41 and is used to control the fan 41's on / off state. In other words, the refrigerator 100 can automatically control the airflow from the refrigerator liner 20 to the freezer liner 10 as needed, thus meeting the requirement of conveniently opening the freezer door. Here, when the controller controls the fan 41 to turn on, the fan 41 can run for a preset time. Specifically, each time the controller controls the fan 41 to turn on, the fan 41 can run continuously for 5 minutes. It can be understood that in other embodiments, the running time of each time the controller controls the fan 41 to turn on may also be 3 minutes, 4 minutes, 6 minutes, or even more minutes, which will not be elaborated here.

[0045] In an embodiment, the refrigerator 100 further comprises a human body sensor (not shown in the figure) for detecting a human body entering into a preset range of the refrigerator 100 to generate a first feedback signal; wherein the human body sensor is electrically connected with the controller, and the controller can control the fan 41 to be turned on according to the first feedback signal. That is, once a human body enters into the preset range of the refrigerator 100, the controller can control the fan 41 to be turned on to balance the air pressure in the freezing inner container 10, so as to meet the use requirement of the subsequent human body opening the freezing door body with smaller force. Here, the human body sensor can be adapted to detect the human body within a range of 1.5 meters around the refrigerator 100. It can be understood that in other embodiments, the human body sensor adapted to detect the preset range of the refrigerator 100 can also be within a range of 1 meter, 1.8 meters, 2 meters or even farther around the refrigerator 100, which will not be described here.

[0046] The human body sensor comprises a radar sensor, an infrared sensor and / or an ultrasonic sensor. It should be noted that the number of the human body sensor and the installation position of the human body sensor on the refrigerator 100 can be arranged according to the use requirement, which will not be described here.

[0047] In an embodiment, the refrigerator 100 further comprises a first detection sensor (not shown in the figure) for detecting the opening of the refrigerating door body (not shown in the figure) on the refrigerating inner container 20 and the freezing door body on the freezing inner container 10 respectively to generate a second feedback signal; wherein the first detection sensor is electrically connected with the controller, and the controller can control the fan 41 to be turned off according to the second feedback signal. That is, when the refrigerating door body and / or the freezing door body of the refrigerator 100 is opened, the controller can control the fan 41 to be turned off, so as to prevent a large amount of air in the environment from entering into the refrigerating inner container 20 and / or the freezing inner container 10 due to the air in the refrigerating inner container 20 being forced to be transported to the freezing inner container 10.

[0048] The first sensor comprises a magnetic sensitive switch, a pressure sensor and / or a proximity switch, and can be integrated into the handle of the refrigerating door body and / or the freezing door body for a person to hold.

[0049] In an embodiment, the refrigerator 100 further comprises a second detection sensor (not shown in the figure) for detecting the closing of the opened freezing door body to generate a third feedback signal; wherein the second detection sensor is electrically connected with the controller, and the controller can control the fan 41 to be turned on according to the third feedback signal. In this way, the air precooling contraction and the air pressure drop in the freezing inner container 10 can be prevented when the freezing door body is just closed. It should be noted that the specific structure of the second detection sensor and the working principle of how to detect the closing of the freezing door body when working can adopt the existing conventional manner, which will not be described here.

[0050] In an embodiment, the refrigerator 100 further comprises a third detection sensor (not shown in the figure) for detecting a defrosting state of the refrigerator 100 to generate a defrosting state signal and a non-defrosting state signal; wherein the third detection sensor is electrically connected with the controller, the controller can control the fan 41 to be closed according to the defrosting state signal, and the controller can control the fan 41 to be opened according to the non-defrosting state signal. So that the forced air supply of the refrigeration liner 20 to the freezing liner 10 will not affect the defrosting of the refrigerator 100. Here, when the third detection sensor generates the defrosting state signal, the refrigerator 100 is in the defrosting state; when the third detection sensor generates the non-defrosting state signal, the refrigerator 100 is in the non-defrosting state. It should be noted that the specific structure of the third detection sensor and the working principle of how to detect the defrosting state of the refrigerator during operation can adopt the existing conventional way, which will not be expanded here.

[0051] It should be noted that when the refrigerator is running in the non-defrosting state, the controller can control the fan 41 to be opened in an intermittent manner according to the ambient temperature of the location where the refrigerator 100 is located. Specifically, when the ambient temperature is below 16 degrees, the refrigerator 100 controls the fan 41 to be opened once every 4 hours, and the running time of the fan 41 each time is 5 minutes; when the ambient temperature is between 16 degrees and 25 degrees, the refrigerator 100 controls the fan 41 to be opened once every 3 hours, and the running time of the fan 41 each time is 5 minutes; when the ambient temperature is between 25 degrees and 38 degrees, the refrigerator 100 controls the fan 41 to be opened once every 2 hours, and the running time of the fan 41 each time is 5 minutes; when the ambient temperature is more than 38 degrees, the refrigerator 100 controls the fan 41 to be opened once every 1 hour, and the running time of the fan 41 each time is 5 minutes.

[0052] As shown in Figure 3 The fan assembly 40 further comprises a bottom shell 42 and a shell cover 43, the bottom shell 42 is fixedly installed on the liner wall 21 of the refrigeration liner 20 and is connected and fixed with the shell cover 43; wherein a containing cavity is formed between the bottom shell 42 and the shell cover 43, the containing cavity is used for accommodating the fan 41, and the containing cavity is in communication with the connecting pipeline 30. That is, the fan 41 can be assembled to the liner wall 21 of the refrigeration liner 20 through the bottom shell 42 and the shell cover 43, which on the one hand can protect the assembly of the fan 41 on the liner wall 21, and on the other hand also ensures that the fan 41 can blow air to the connecting pipeline 30 when working.

[0053] To sum up, when the refrigerator 100 is working, the controller can control the fan 41 to be turned on according to the use requirement, so as to forcibly transport the air in the refrigeration inner container 20 into the freezing inner container 10, and realize the air circulation between the refrigeration inner container 20 and the freezing inner container 10, so as to balance the air pressure in the freezing inner container 10, thus, the pressure difference between the freezing inner container 10 and the outside air can be reduced, and thus the opening door force required when the user opens the freezing door (not shown in the figure) of the freezing inner container 10 again can be reduced, so as to facilitate the opening of the door.

[0054] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that the combinations are within the scope of the present disclosure.
