Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a drawer type door.

2. Description of the Related Art In recent years, for articles stored in a refrigerator, it has been proposed to partition and form a chamber according to the articles.

As such a chamber, for example, as shown in Japanese Utility Model Publication No. Sho 61-22233, an upper door, a middle door and a drawer type door are arranged in the vertical direction, and a frame extending from the drawer type door to the inside of the refrigerator is provided to provide an upper surface. The container was opened and placed.

A pull-out door equipped with such a container has been used for storing vegetables and fruits so that the user can bend over and take in and out the container from above.

However, although it is a container of the size of the full width of the refrigerator, if you want to store bottles, cans, and small items, you can not only store them in a row in the vertical direction, but always Since it has to be taken out with cancer, it is difficult to bring it out with a heavy bottle or can, and storing food (vegetables and fruits) to be eaten directly, a can and a bottle in the same place,
It gives a feeling of unsanitary to the user.

Further, bottles and cans are generally stored by forming pockets in a door back located inside the width door. However, inside doors and the like supported the upper and lower ends on the right side with pins, and this pin could be used as an axis to open and close, but the heavy items of bottles and cans added to the door, the door tilted downward, and the main body and middle The sealability via the gasket with the door deteriorated, and the cooling capacity sometimes deteriorated.

In view of the above problems, it is an object of the present invention to provide a refrigerator having vertically extending drawer doors for accommodating bottles and cans vertically.

Means for Solving the Problems In order to solve the above problems, the refrigerator of the present invention has an outer box, an inner box, a foamed heat insulating material filled between both boxes, and a single piece projecting upward from the bottom surface of the inner box. A projecting wall filled with the foamed heat insulating material; a partition wall made of a synthetic resin that comes into contact with the top surface and the back wall of the storage chamber formed by the projecting wall and the inner box to form two left and right chambers; Doors arranged in front of the left and right two chambers, a control device having a blowout port penetrating the partition wall and projecting cool air to both chambers, and a side wall extending from the door to the inside of the storage chamber and facing each other. A metal frame having a shelf slidably attached to a fixed rail fixed, a shelf made of synthetic resin having a container-like upper surface extending into the storage chamber above the door, and the shelf Back made of synthetic resin fixed to the rear end and the rear end of the frame with screws. It is composed of a wall and a cold air introduction duct which is formed on the back surface of the back wall and faces the air outlet in a state where the door is closed and which allows cold air to flow between the shelves from the opening of the back wall.

By providing the duct for guiding the cool air on the back wall of the door by the above means, the cool air can be introduced into the shelf, so that the uniform temperature can be maintained. Further, since the duct is formed on the back wall, when the door is opened, the discharged cool air is less likely to leak to the outside.
