Refrigerator

Abstract

A refrigerator, comprising a refrigerator body defining a first chamber, and a door body comprising a main door for opening/closing the first chamber and defining a second chamber, and a secondary door for opening/closing the second chamber; an air supply port and an air return port are formed on the rear wall of the main door; a dew removal air channel is defined in the rear wall; and a plurality of dew removal holes are backwards formed on the front surface of the rear wall. In a cooling cycle mode, air in the first chamber enters the second chamber through the air supply port and then returns to the first chamber through the air return port; or in a dew removal mode, air in the first chamber enters the dew removal air channel to partially flow to the front surface of the rear wall to remove condensed dew thereon.

What is claimed is: 
     
         1 . A refrigerator, comprising a refrigerator body and a door body, wherein a front side of the refrigerator body is open to define a first chamber; the door body comprises a main door and a secondary door; the main door is used for opening and closing the first chamber and defining a second chamber, and the secondary door is used for opening and closing the second chamber, wherein
 an air supply port and an air return port are formed in a rear wall of the main door and both communicated with the first chamber and the second chamber; the rear wall is hollow, a dew removal air duct communicated with the first chamber is defined in the rear wall, and a plurality of dew removal holes communicated with the second chamber and the dew removal air duct are backwards formed on a front surface of the rear wall; and the refrigerator is configured to be:   in a cooling cycle mode that air in the first chamber is allowed to enter the second chamber through the air supply port, and then return to the first chamber through the air return port; or   in a dew removal mode that the air in the first chamber is allowed to enter the dew removal air duct, so that part of an air flow flows to the front surface of the rear wall through the dew removal holes, to remove condensed dew on the surface of the rear wall.   
     
     
         2 . The refrigerator according to  claim 1 , wherein
 the dew removal air duct is provided with an inlet and an outlet which are communicated with the first chamber; and   the refrigerator is configured to make the inlet and the outlet in a closed state and an open state respectively when in the cooling cycle mode; or make the inlet and the outlet both in the open state when in the dew removal mode.   
     
     
         3 . The refrigerator according to  claim 2 , wherein
 the inlet penetrates a side wall of the air supply port to communicate with the air supply port.   
     
     
         4 . The refrigerator according to  claim 3 , wherein
 the outlet penetrates a side wall of the air return port to communicate with the air return port.   
     
     
         5 . The refrigerator according to  claim 4 , wherein
 the air supply port and the air return port are located at a top and a bottom of the rear wall, respectively.   
     
     
         6 . The refrigerator according to  claim 5 , further comprising:
 a damper, installed at the air supply port and configured to controllably move to a cooling state in which the inlet is closed and the air supply port is turned on, or move to a dew removal state in which the inlet is opened and the air supply port is closed.   
     
     
         7 . The refrigerator according to  claim 6 , wherein
 one end of the damper is rotatably installed on a front edge of the inlet to be rotated to the cooling state or the dew removal state.   
     
     
         8 . The refrigerator according to  claim 1 , further comprising:
 a fan, installed at the air supply port to promote the air in the first chamber to flow toward the air supply port.   
     
     
         9 . The refrigerator according to  claim 1 , wherein
 in a direction from the air supply port to the air return port, the arrangement density of the dew removal holes gradually decreases.   
     
     
         10 . The refrigerator according to  claim 1 , wherein
 the dew removal holes are long strip holes whose length direction is parallel to the airflow direction of the dew removal air duct.
