Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a refrigerator in which cool air is cooled by a cooler and circulated within a storage chamber by a blower.

As shown in Publication No. 33224, a cooler is installed at the back of the freezer compartment, and a blower installed above the cooler at the center of the back of the freezer compartment blows the cold air cooled by the cooler upward. At the same time, the cold air discharged from the blower was first guided to the right side, avoiding the cooler, and then dropped downward from there to supply the cold air to the refrigerator compartment.

(c) Problems to be Solved by the Invention According to the configuration, the cold air to be supplied to the refrigerator compartment is once blown out forward by the blower, then detoured largely to the right side, and then entered into the duct extending downward. Because of the downward movement of the air, there is a large flow resistance and the disadvantage is that there is a large loss in the circulation of cold air.

In addition, since the cold air duct of the refrigerator is formed in the center of the refrigerator, the duct requires more storage space at the back of the refrigerator, which reduces the shelf area and sacrifices the internal volume. There is the problem of being exposed.

On the other hand, household refrigerators have multiple shelves on which items can be placed, but it is troublesome to take items in and out of the back, and items stored in the back may rot forever without being taken out. However, there was a drawback that the shelves could easily be rotated, making it highly desirable to have a rotatable shelf.

The present invention aims to solve such problems.

(d) Means for Solving the Problems The present invention provides a rotatable disc-shaped shelf in the refrigerating compartment of a refrigerator having a box with a substantially rectangular cross section, and a rear corner of the refrigerating compartment. A cold air supply duct communicating with the cold air discharge side of the cooler is disposed on one side, and an insertion light is disposed on the other side, and a door opening is formed at the front corner of the refrigerator compartment.

(E) Function According to the present invention, a rotatable shelf is provided in the refrigerator compartment, so by rotating this shelf, items at the back can be moved to the front, and articles can be taken in and out. becomes more convenient and improves usability.

In addition, a cold air supply duct that communicates with the cold air discharge side of the cooler is placed on one side of the back corner of the refrigerator compartment, and an internal light is placed on the other side, allowing the arc of the shelf to extend to the center of the back of the refrigerator compartment. Not only can space be used effectively, but the thickness of the entire refrigerator can also be reduced, and the shelf area can be increased. Furthermore, since the door pocket is formed to protrude from the front corner of the refrigerator compartment, the pocket can be placed along the circular shelf, making effective use of space inside the refrigerator and smoothing the circulation of cold air. However, in combination with the arrangement of the ducts and interior lights, there is almost no dead space inside the refrigerator, even with a box with a roughly rectangular cross section and a circular shelf. When installing a refrigerator, it is possible to provide an easy-to-use refrigerator with rotating shelves while maintaining convenience and installation space. Furthermore, even if multiple rotating shelves are installed in the refrigerator compartment, if the ducts and light-emitting covers for the internal lights are arranged in a vertically elongated manner across the entire refrigerator compartment, cool air can be supplied to all of the compartments. It can be brightly illuminated.

In the freezer compartment 2 and the refrigerator compartment 10, a plurality of disc-shaped shelves 24 and 25 made of transparent synthetic resin are rotatably provided. Further, disc-shaped shelves 26 and 27 are rotatably provided on the upper surfaces of the partition wall 9 and the partition plate 12, respectively. By rotating these shelves 24 or 25, items placed at the back can also be moved to the front,
Can be taken out easily.

Next, the structure around the freezer compartment 2 will be explained with reference to FIGS. 4 to 6. The rear part of the freezer compartment 2 is divided by a semi-circular back plate 28 that follows the arc of the shelf 24, and the shelf 24 of the freezer compartment 2 is a transparent box that is detachably supported on the front surface of the inner box 6 and the back plate 28. A holding plate 29 made of synthetic resin is attached on top and is rotatable by a rotating shaft 30 and an outer roller 31. Further, the shelf 26 is rotatably held by rollers 39 of the partition wall 9-h.

At this time, the front end of the shelf 24 is sized to protrude further forward than the opening edge of the heat insulating box 4, that is, the opening edge of the outer box 5.
Further, the front end of the partition wall 9 also has a curved shape that protrudes forward accordingly. In addition, in response to this, the door 20 (
The other doors (similarly) are also configured to have a curved cross-section so that their inner surfaces protrude forward.

On the other hand, a molded heat insulating material 32 and a partition plate 33 are provided behind the back plate 28.
A cooling chamber 3 is constituted by these, and a cooler 34 included in the refrigeration cycle is housed and installed within this cooling chamber 3. This cooler 34 is a so-called cross fin tube type heat exchanger in which a plurality of metal fins are attached to a refrigerant pipe.
It is provided vertically along the back surface of the inner box 6, and furthermore, as shown in FIG.
