[0054] In some embodiments, the cabinet door 200 includes a shell 201 , and the shell 201 is rotatably connected to the cabinet body 100 .

[0055] In some embodiments, the cabinet door 200 includes an inner liner 202 , which is disposed inside the shell 201 . A foaming space is formed between the inner liner 202 and the shell 201 , and the foaming space may be filled with a foaming layer.

[0056] In some embodiments, the cabinet door 200 includes a pressure relief port 2021 , which is disposed on the inner liner 202 , and is communicated with the accommodating cavity 101 . The pressure relief port 2021 is a through hole that penetrates the inner liner 202 .

[0057] In some embodiments, the cabinet door 200 includes a pressure relief box 203, which is disposed between the inner tank 202 and the shell 201. The pressure relief box 203 is disposed corresponding to the pressure relief port 2021, and the pressure relief box 203 is respectively connected to the pressure relief port 2021 and the outside of the cabinet 100.

[0058] The pressure relief box 203 includes a matching portion 2031 . A track 2022 is provided on the edge of the pressure relief port 2021 . The matching portion 2031 matches with the track 2022 so that the pressure relief box 203 can be slidably connected to the inner container 202 .

[0059] When the door 200 of the refrigerator 1000 is closed, the air in the accommodating cavity 101 of the cabinet 100 contracts to form negative pressure, making it difficult to open the door. By providing a pressure relief box 203 that is connected to the pressure relief port 2021 and the outside of the cabinet 100, when the door is opened, the airflow outside the cabinet 100 can enter the accommodating cavity 101 through the pressure relief box 203, balance the air pressure, and make the door open smoothly.

[0060] In the embodiment of the present application, a sliding connection is set between the pressure relief box 203 and the inner liner 202, and the mating portion 2031 of the pressure relief box 203 is matched with the track 2022 on the inner liner 202, so that the pressure relief box 203 is slidably connected to the inner liner 202, and there is no need to use tape to connect the pressure relief box 203 and the inner liner 202, thereby making the installation of the pressure relief box 203 convenient and quick.

[0061] In some embodiments, the cabinet door 200 may include a pressure relief valve, which is arranged between the inner tank 202 and the shell 201. The pressure relief valve is respectively connected to the pressure relief box 203 and the outside of the cabinet 100. The pressure relief valve can be used to connect the pressure relief box 203 with the outside of the cabinet 100 or disconnect the connection between the pressure relief box 203 and the outside of the cabinet 100.

[0062] When the door 200 of the refrigerator 1000 is closed, the air in the accommodating cavity 101 of the cabinet body 100 contracts to form negative pressure, making it difficult to open the door 200. By providing a pressure relief valve, when the door is opened, the air flow outside the cabinet body 100 can flow into the pressure relief box 203 through the pressure relief valve, and then flow into the accommodating cavity 101 through the pressure relief box 203, thereby balancing the air pressure in the accommodating cavity 101 and making the opening of the door 200 smoother.

[0063] In some embodiments, when the cabinet door 200 opens the access opening 102, the pressure relief valve connects the pressure relief box 203 with the outside of the cabinet 100. The airflow outside the cabinet 100 can flow into the pressure relief box 203 and the accommodating cavity 101 through the pressure relief valve, thereby balancing the air pressure in the accommodating cavity 101 and facilitating the opening of the cabinet door 200.

[0064] In some embodiments, when the cabinet door 200 closes the access opening 102, the pressure relief valve disconnects the pressure relief box 203 from the outside of the cabinet 100. A paddle is provided in the pressure relief valve. When the cabinet door 200 closes the access opening 102, the paddle closes the connection between the pressure relief valve and the outside of the cabinet 100 under the action of gravity, so that the accommodating chamber 101 is isolated from the outside of the cabinet 100, preventing external air and water vapor from entering the accommodating chamber 101, thereby achieving the effect of reducing frost.

[0065] In some embodiments, the pressure relief valve is a gravity pressure relief valve, which is disposed inside the cabinet door 200. The cabinet door 200 is flipped open and closed to change the gravity state of the gravity pressure relief valve, thereby controlling the opening of the gravity pressure relief valve to connect the pressure relief box 203 with the outside of the cabinet 100, or disconnecting the pressure relief box 203 from the outside of the cabinet 100.
