A shelf for loading food is provided in the freezer compartment and the refrigerating compartment of the refrigerator.

In recent years, the consumption pattern of food is in a trend of purchasing a large amount of food at once, and accordingly, the refrigerator is enlarged and many foods are stored at the same time. Therefore, it is important to accurately understand the inventory and distribution period of food stored in the refrigerator.

Conventional refrigerators are provided with various contents in order to manage the type of food being stored, storage time, and distribution period. For this purpose, an operation panel is provided on the refrigerator door so that food such as the kind of food being stored, Information is directly input from the user and managed.

In addition, the refrigerator has a bar code device, and in case of a food on which a bar code is printed, the food information is read through the bar code device to minimize the hassle of input.

In the conventional refrigerator, techniques for roughly grasping the loading position and the remaining amount of the food stored in the refrigerator have been disclosed.

However, the conventional refrigerator has inconvenience that the user must directly open the door of the refrigerator and visually confirm the loading position and remaining amount of the food.

Accordingly, it takes a lot of time to open the door and check the presence or absence of food for each shelf, so that the cold air in the refrigerator flows out and the power consumption is increased in the process of regenerating the cold air to compensate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator in which a user can check a loading position and a remaining amount of food to be stored without opening the door .

Another object of the present invention is to provide a refrigerator which can prevent freezing and outflow of freezing and refrigerating chambers and reduce power consumption.

Another object of the present invention is to provide a refrigerator which can inform the user of the appropriate purchase time of the food because the change of the remaining amount of the food can be confirmed.

In order to accomplish the above object, the present invention provides a refrigerator comprising: a storage space formed by a refrigerator compartment and a freezer compartment; a shelf installed in the refrigerator compartment and the freezer compartment; and a door for opening and closing the storage compartment, An input control unit for processing information measured by the sensing sensor, and a display unit installed outside the door to display a loading position and a remaining amount of the food under the control of the input control unit, Wherein the weight sensor or the position sensor is installed at two or more intervals in a lateral or longitudinal direction of the shelf at predetermined intervals.

Here, it is preferable that the display unit is constituted by two or more shelf display portions in the same manner as the arrangement positions and the number of shelves provided in the refrigerating and freezing chambers.

In addition, the shelf display unit preferably includes two or more sensor display units, which are the same as the arrangement positions and the number of the detection sensors.

According to the refrigerator of the present invention, the loading position and the remaining amount of the food stored in the shelf are detected by the detection sensor, and the user can check the display position on the external display without opening the door.

As a result, it is not necessary to open the door to grasp the loading position and remaining amount of the food, thereby preventing cold air from flowing out of the freezing room and the refrigerating room, thereby reducing power consumption.

Further, since the change of the remaining amount of the food can be confirmed, it is effective to inform the proper purchase time of the food.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
