DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator commonly used in ordinary households.

[0002]

2. Description of the Related Art A conventional home refrigerator generally comprises a refrigerator compartment and an openable and closable door for closing an opening of the refrigerator compartment, and the entire exterior thereof is generally formed of a material such as opaque plastic. It is a target. In addition, there is one in which an operation screen of a storage display device capable of storing or detecting a cooking menu, a schedule, or the like is provided on a front surface of the door portion.

[0003]

In recent years, household refrigerators have become extremely popular and their capacity has been increased in accordance with changes in lifestyle. As a result, the doors are frequently opened and closed for checking a large number of stored items, taking them in and out, or checking stock items, and the opening time for each time is greatly increased.
In some cases, an operation screen of a storage display device such as a cooking menu is provided on the front of the door. However, the operation is indispensable to check inventory items, and the frequency of opening and closing is further increased. Together, these tend to increase the number of times the door is opened and closed and the time for opening the door in the future. Due to the increase in the number of times the door is opened and closed and the length of the opening time, the refrigerator's refrigeration storage performance decreases,
In addition, an increase in power consumption is inevitable. In addition, the convenience of the angle has not been demonstrated. The present invention has been made to solve the above-mentioned problems, and to provide a refrigerator which can be used more conveniently and effectively in daily life, has excellent refrigeration storage performance, and can realize energy saving. Aim.

[0004]

A refrigerator having a refrigerator compartment and an openable and closable door for closing an opening of the refrigerator compartment, wherein the refrigerator is provided with a front door and a recess formed in an inner surface of the front door. An inner door made of a plate-shaped transparent body which can be selectively opened and closed by opening and closing the front door by closing an opening of the chamber, and a storage pocket is provided in the front door or the inner door; A feature is that an operation screen of a storage display device such as a cooking menu is arranged on the inner surface of the door.

[0005]

[Function] By providing an inner door that can be selectively opened and closed, even when the front door is opened, the state in which the inner door closes the opening of the refrigerator compartment can be maintained. Can be avoided. Further, the storage pocket provided on the front door or the inner door serves as a second refrigerator. In addition, by making the inner door a plate-shaped transparent body, the refrigerator compartment can be visually checked from the outside without opening,
The inner door does not need to be opened or closed except for taking in and out. In addition, by disposing the operation screen of the storage display device such as a cooking menu on the inner surface of the front door, it is possible to perform operations while visually confirming the storage items in the refrigerator compartment and the operation screen with each other. .
