Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0136274 filed on Oct. 30, 2019 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

1. Field

The disclosure relates to a door having an improved corner structure and a home appliance having the same.

2. Description of the Related Art

A home appliance includes a chamber that implements a function of a device, such as a cooking room or a washing room, and a door that opens and closes the chamber.

The door includes a chassis forming the external appearance thereof, glass, and an inner frame. The chassis is composed of a single panel that is bent at upper, lower, left, and right sides to form the external appearance of the door. In this case, a corner portion of the chassis is cut out for bending. A user may be injured by a sharp shear surface formed at the corner portion.

In order to prevent a user from being injured by the sharp shear surface, the conventional technology uses a structure in which a corner portion having a shear surface is welded or an incision is formed in other portions rather than a corner portion and covered with a cap.

However, such a welding requires a complicated process, causing a difficulty in securing a certain quality. In addition, without forming the incision on the corner portion, the corner portion is formed to have an edge with a small radius, thereby causing the surface to be uneven.

In addition, when the cap and the chassis are fixed to each other with a fastening member in order to prevent the panel from being separated, a stress may directly act on the cap, and the durability of the cap may be deteriorated.

The fixing member 300 may include a steel material on which pressing molding is performable. However, the disclosure is not limited thereto, and the fixing member 300 may include a material having a greater rigidity than a material of the cover member 500.

With such a configuration, the manufacturing of the cover member 500 may be facilitated while improving the durability of the cover member 500.

In addition, with the configuration of the cover member 500, the corner of the door 100 may be formed to have a smooth surface without using welding. Therefore, the manufacturing process of the door 100 may be simplified. In addition, a constant level of quality may be guaranteed and the aesthetic quality of the door 100 may be improved.

As is apparent from the above, the cover member configured to cover the sharp incision portion formed on the chassis of the door can prevent a user from being injured by the sharp incision portion.

The manufacturing process of the door can be simplified by covering the incision portion without welding.

The chassis corner portion of the door is formed to have a small radius, so that the aesthetic quality of the door can be improved.

A stress acting on the cover member is minimized using a separate fixing member, so that the durability of the cover member can be secured.

Although the present disclosure has been described with various embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
