Home appliances with doors attached to the front

Abstract

The present invention is applicable to home appliances with doors on the front, such as refrigerators, washing machines, dishwashers, cosmetic refrigerators, rice refrigerators, warming cabinets, and freezers. By applying the present invention to such products, it eliminates the need to separately secure space for opening and closing the door, improving the space utilization efficiency when users install and use the product. Furthermore, since the door is opened and closed automatically by a motor with a reduction gear, not only is convenience improved, but it also enables various attempts toward product design innovation, and is expected to promote the spread of hinge-free home appliances.
