DISHWASHER

TECHNICAL FIELD

The present disclosure relates to a dishwasher, and more particularly, to a dishwasher having a cover panel mounted on the front of a door.

BACKGROUND ART

A dishwasher is a home appliance used to clean contaminants, such as food residue, on dishware, cookware, and the like (hereinafter referred to as an ‘object to be washed’) by using high-pressure washing water sprayed from a spray arm.

The dishwasher may clean an object to be washed in an inner space of a tub. The front of the tub may be open to be covered by the opening and closing of a door, and a cover panel defining the outer shape or appearance may be mounted on the front of the door.

The cover panel may be made of various materials. A user may choose a cover panel for installation on the door in consideration of harmony and unity in interior design such as harmony with the surrounding furniture. A range of weight or load of the cover panel may vary depending on the material of the cover panel. When a material with a high density is selected, it may be difficult to keep the door open due to a load acting on the door.

In the case of a cover panel with heavy weight, a load of the cover panel is concentrated in a portion where the cover panel is mounted on the door to thereby causing a damage of the door where the cover panel is mounted on the door. Further, when the cover panel is movably mounted on the door, the load acting on the door is increased when the cover panel is moved. This may result in structural deformation or damage of the door where the cover panel is mounted on the door.

European Patent Registration EP2407723B1, which is hereby incorporated by reference, discloses a guide structure for guiding the movement of a cover panel in a portion where a panel is mounted. However, in that publication, a structure for supporting the cover panel with heavy weight by a door mounted on the cover panel is not disclosed, and thus a way to solve the problem is not provided.

As disclosed in the related art, in order to distribute a load of the cover panel, a cover panel for an upper cover door that is mounted on an outer door may be installed in addition to the outer door that is usually disposed at the rear of the cover panel. However, a control panel and the like are provided at the upper cover panel that is disposed on the outer door, the upper cover panel may have weaker strength than the outer door. In this case, when an excessive load is applied to the upper cover door, damage or warping may occur. In addition, power or dust generated in the process of producing the configuration of the upper cover door may be easily exposed to a user.
