Description

refrigerator

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

In recent years, large refrigerators have become widespread with increasing needs such as bulk buying. Refrigerators that have three or more rooms are common, such as a refrigerator room, a freezer room, and a vegetable room. In the past, hinge-type revolving doors were common, but nowadays, refrigerators with drawer-type doors occupy a large number of rooms such as freezer rooms and vegetable rooms.

In a conventional refrigerator, as disclosed in Patent Document 1, a drawer cap such as a freezer compartment or a vegetable compartment has a door cap attached to the upper end of the door body, and the door cap has a recess for pulling out a door belt. The finger insertion portion is configured. 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 is used as a finger hook portion. The door cap is a space that can be filled with urethane at both left and right ends, and maintains heat insulation, and a finger insertion portion is provided at the center. The door cap allows the second member to escape in the depth direction of the refrigerator only at the finger insertion portion at the center to form a space for finger hooking. The upper end of the second member is joined to the first member, but the upper end of the second member abuts against the first member while providing a urethane leakage prevention structure. Thereby, the structure of the finger hook is formed.

Japanese Patent Laid-Open No. 10-205806

However, as the size of the refrigerator increases and the load caused by stored food increases, the load on the structure of the finger-hanging part of the drawer door increases. For this reason, in the drawer door, the importance of the ease of pulling out and the strength of the structure of the finger rest is increasing. In the drawer door structure disclosed in Patent Document 1, the fitting structure between the members constituting the finger hanging portion is located far from the point where the load is applied, and the finger hanging portion is configured when the load is applied. It fits so that the member to perform may leave | separate. For this reason, when a large load is applied to the finger-hanging portion, the finger-hanging portion is deformed, and there is a problem that the members constituting the finger-hanging portion are separated and floated. Also, even during manufacturing, there is no fitting structure for fixing the vertical position between the members constituting the finger-hanging part, so it is necessary to fix with a sealing material, etc., and the assembling workability is poor. There has been a problem that half-insertion is likely to occur.

The present invention has been made to solve the above-described problems, and a refrigerator with good assembling workability of the finger-hanging portion that does not cause deformation or lifting of the fitting portion even when a large load is applied to the finger-hanging portion. The purpose is to provide.

A refrigerator according to the present invention includes a heat insulating box body having an opening on a front surface and an interior partitioned into a plurality of rooms, and a plurality of doors closing the room so that the opening can be freely opened and closed. The door is a drawer door, and the drawer door has a handle structure at an upper end, and the handle structure includes a handle part that forms a finger hook part, a handle holding part that holds the handle part, and the handle holding part. An upward engagement portion that restricts upward movement of the handle component relative to the component, and a forward / backward engagement portion that restricts forward / backward movement of the handle component relative to the handle holding component.

According to the present invention, as described above, the refrigerator according to the present invention is configured such that when the handle part and the handle holding part constituting the handle structure are engaged in the vertical direction and the front-rear direction, the drawer shape is loaded. However, since the floating is suppressed by the rib, it can be pulled out while suppressing deformation. In addition, by engaging the handle part and the handle holding part in the vertical direction and the front-rear direction, the handle part and the handle holding part are not displaced from each other even when the foam door is filled with the foam filler.
