Description

The present invention relates to a refrigerator, and more particularly to a structure of a finger hook portion of a drawer door.

In recent years, large refrigerators have become widespread due to an increase in needs such as bulk buying. Refrigerators, which have three or more rooms, such as refrigerating rooms, freezing rooms, and vegetable rooms are becoming common. In the past, hinged revolving doors were common, but nowadays, in rooms such as freezer compartments and vegetable compartments, a large number of refrigerators have drawer-type doors.

In a conventional refrigerator, as disclosed in Patent Document 1, a drawer door such as a freezer compartment or a vegetable compartment has a door cap attached to an upper end of a door body, and the door cap has a recess for pulling out a door band. The finger insertion part is formed. The door cap is composed of two members, a first member and a second member. The first member has a flange extending downward, and this flange serves as a finger hook portion. The door cap has a space in which urethane can be filled at both left and right ends to maintain heat insulation, and has a finger insertion portion at the center. The door cap allows the second member to escape in the depth direction of the refrigerator only in the finger insertion portion at the center to form a space for hanging the finger. The upper end of the second member is joined to the first member, but the upper end of the second member is partially lapped with the first member and is abutted while having a urethane leakage prevention structure. Thereby, the structure of the finger hook is formed.

However, as the size of the refrigerator becomes larger and the load of stored foods increases, the load on the structure of the finger hook of the drawer door also increases. Therefore, in the drawer door, the importance of easiness of pulling out and the strength of the structure of the finger-holding portion are increasing. In the drawer door structure disclosed in Patent Document 1, the fitting structure of the members forming the finger hooks is located far from the point where the load is applied, and when the load is applied, the finger hooks are configured. The members to be engaged are fitted so as to be separated from each other. Therefore, when a large load is applied to the finger hook, the finger hook is deformed, and members forming the finger hook are separated from each other and float up. Further, even at the time of manufacturing, since there is no fitting structure for fixing the vertical position between the members constituting the finger-holding portion, it is necessary to fix with a sealing material or the like, and the assembly workability is poor. However, there was a problem that half insertion was likely to occur.

The present invention has been made in order to solve the above problems, and a refrigerator with good workability for assembling the finger-holding portion does not occur even if a large load is applied to the finger-holding portion without causing deformation or lifting of the fitting portion. The purpose is to provide.
