Example 2

This embodiment will explain the refrigerator of the present invention in detail.

The refrigerator of the embodiment comprises a mechanism 1 with the functions of water drainage and pressure regulation in the technical scheme of the embodiment 1. The refrigerator of the embodiment is provided with the mechanism 1 with the water drainage and pressure regulation functions in any technical scheme in the embodiment 1, and through the action of the mechanism 1 with the water drainage and pressure regulation functions, when a door body of the refrigerator needs to be opened, outside air can enter the compartment 21 of the refrigerator through the accommodating cavity, so that the air pressure in the compartment 21 is increased, and the door is easy to open; when the door of the refrigerator is closed, the air in the compartment 21 can be discharged through the drain pipe 14, so that the pressure in the compartment 21 is reduced, and the sealing performance of the compartment 21 is enhanced. In addition, the refrigerator of the embodiment can ensure the reliability of the refrigerator by discharging the defrosting water through the mechanism 1 with the functions of water discharging and pressure regulating. The refrigerator of this embodiment promptly has solved among the prior art because of the interior negative pressure that leads to the difficult technical problem that opens of door body of box 2.

The compartment 21 in this embodiment refers to a receiving portion of a refrigerating compartment and/or a freezing compartment of a refrigerator. The refrigerating chamber of the refrigerator of the present embodiment may be located at an upper portion of the cabinet 2 or a lower portion of the cabinet 2.

As shown in fig. 4 or 5, the flow of gas in the process of opening and closing the door of the refrigerator will be described in detail by taking the refrigerating chamber located at the lower portion of the cabinet 2 as an example.

When the door body of freezer is opened, in the twinkling of an eye that the door body was opened, the atmospheric pressure of cold-stored room changes, make outside air gush into through air intake 121 and hold in the chamber, the air that gushes into and hold in the chamber promotes wind-break portion 131 and rotates and makes wind-break portion 131 be in the open mode, outside air can get into in the blast pipe 111, outside air gets into in the cold-stored room through the bleeder vent on the indoor exhaust port 211 of freezer again, make the pressure of cold-stored room inside sharply rise in the twinkling of an eye, thereby reach balanced state with outside pressure rapidly, the refrigerator door is opened. On the contrary, when the door body of the refrigerating chamber is closed, at the moment when the door body is closed, the air pressure of the refrigerating chamber changes, the air in the refrigerating chamber enters the exhaust pipe 111 through the air holes on the exhaust port 211, at this time, because the air flowing out of the refrigerating chamber is not enough to push the wind blocking part 131 to rotate to be in an open state, the wind blocking part 131 is in a wind blocking state, the air in the exhaust pipe 111 can be discharged through the drain pipe 14, and the good sealing performance in the refrigerating chamber is kept.
