Description

refrigerator

The present invention relates to a refrigerator, and more particularly to a fall-off prevention structure of a revolving door piece that rotates about a hinge provided at a front opening portion.

In the revolving door piece provided in the front opening portion of the refrigerator, a thin steel plate such as a printed steel plate or a thin steel plate is used as the outer surface of the door piece design. In the revolving door piece of the steel sheet surface material, the flat steel plate is formed in a substantially C shape when viewed from the side, and a reinforcing plate made of a steel plate is attached to sandwich the upper and lower sides (see, for example, Patent Document 1) .

Further, the reinforcing plate forms a hinge engaging portion, and the hinge engaging portion is rotatably supported by a hinge provided in the refrigerator body.

In addition, in recent years, designing is highly valued, so reinforced glass is often used as an outer material for the design of the door piece. In the revolving door sheet using the glass surface material, since the tempered glass cannot be formed into a C-shape like the side surface of the steel sheet, the resin is formed on the four sides of the flat tempered glass. Enclosed in a frame shape, the adhesive is adhered to the four sides of the tempered glass with an adhesive.

Moreover, the hinge bearing component is fixed to the resin protector, and the hinge bearing component is supported by a hinge provided in the refrigerator body in a freely rotatable manner.
