Description

Convenient drawer type refrigerator {Easy-to-use refrigerator of drawer type}

The present invention relates to a drawer-type refrigerator equipped with a sliding door, and more particularly, to a convenient-use drawer-type refrigerator in which a refrigerating and freezing chamber is automatically drawn out while sliding in a front-facing direction so that the refrigerator can be conveniently used.

BACKGROUND ART In general, a refrigerator is a home appliance that allows food to be stored at a low temperature in an internal storage space that is turned by a door. It is designed to store food in an optimal state.

Such refrigerators are becoming larger and more multifunctional in accordance with changes in eating habits and user preferences, and refrigerators equipped with various structures and convenience devices are being released to provide user convenience and freshness of stored food.

Typically, a refrigerator includes a food storage unit provided with shelves to form a storage space for food. In addition, the food storage unit is provided with a rotating door for opening and closing the storage space.

However, the refrigerator is provided with a packing made of an elastic material such as rubber to prevent cold air from escaping between a food storage unit for storing food and a door for opening and closing the food storage unit. This packing is elastically deformed when the door is closed and is closely adhered to the food storage unit to obtain the effect of sealing the inside of the food storage unit to the external space, while the elastic restoring force acts in the direction that the door moves away from the food storage unit. It is necessary to have a configuration that suppresses the door from automatically opening by the elastic restoring force of the A configuration for suppressing automatic opening of the door in a closed state is provided at the point where the door and the food storage unit abut or the hinge of the door, and includes a magnet, a spring, or an eccentric cam. However, such a configuration acts as a rotational resistance for the user when the door is initially opened, and when the user is holding an object to be stored in the refrigerator with both hands, there is a inconvenience in using that the user has to put down the object to open the door. . In addition, the conventional food storage unit is a stand-type inside the refrigerator or freezer compartment, and when the rotating door is opened to store food in the food storage unit or take out the stored food, the food stored inside the food storage unit is not easily visible. Since the food is stored deep inside, it is inconvenient to take out the food, so the inconvenience of using the conventional refrigerator with a rotating door and a stand-type food storage unit is increasing.
