  In the door of the refrigerator of Patent Document 1, when injecting the foamed heat insulating material, the jig is placed in the handle and the injection is performed in a state where the positional relationship between the connection component and the side panel is maintained. However, when the foaming heat insulating material is completely injected and the placing jig is removed, the connecting parts tend to be inclined before the foaming heat insulating material is molded and fixed. It is considered that this is due to rattling due to variations in the size of the connecting portion between the side panel and the insertion port of the connecting component, the pressure of the foam insulating material, and the like.

  Specifically, the inclination of the connection component tends to incline in a direction in which the connection portion between the side panel and the connection component moves from the normal position to the design panel side. The connecting portion between the side panel and the connecting component is closer to the center portion of the door in the left-right direction than the handle portion, is opposed to the design panel, and is surrounded by a foamed heat insulating material. For this reason, when the connecting component is tilted, the connecting portion between the connecting component and the side panel pushes the design panel outward together with the foamed heat insulating material around the side panel, which causes the design panel to be deformed.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a refrigerator door capable of suppressing deformation of a design panel during manufacturing, and a refrigerator including the door.

The door of the refrigerator according to the present invention is arranged at the design panel forming the front surface of the door, the side panel forming the side surface in the left-right direction of the door, and the end portion of the design panel in the left-right direction, and the design panel is inserted. The connector includes a first insertion opening and a second insertion opening into which the side panel is inserted, and a connecting component that holds the design panel and the side panel individually. Has a concave portion that is concave toward one side and extends in the up-down direction, and the end portion of the concave portion on the design panel side is inserted into the second insertion opening of the connecting component and connected to the connecting component. A hand-holding portion into which a hand is inserted when opening and closing is formed , and the hand-holding surface, which is a contact surface with which the hand comes into contact, is configured such that a part of the connecting component and a part of the side panel are flush with each other. There is something.

  A refrigerator according to the present invention includes the above refrigerator door.

  In the door of the refrigerator and the refrigerator of the present invention, the handle portion is configured by the concave portion of the side panel, and the connecting portion between the side panel and the connecting component is located outside the central portion side in the left-right direction of the door. For this reason, even if there is looseness due to dimensional variation in the connecting portion between the connecting component and the side panel, the connecting portion between the connecting component and the side panel is located at the end portion in the left-right direction of the design panel.
