The purpose is to provide excellent refrigerators.

(d) Means for Solving the Problems The present invention provides a refrigerator in which a disc-shaped shelf is rotatably provided inside the refrigerator, and a groove formed on both side walls of an inner box of the refrigerator;
It is equipped with a holding plate that is inserted into this groove so that it can be pulled out, and a disk-shaped shelf that is rotatably installed on this holding plate, and claw pieces that exert large elasticity when inserted are provided on both sides of the holding plate. At the same time, a recess for receiving the claw piece is formed in the holding plate mounting surface of the groove.

(E) Function With the above-described structure of the refrigerator of the present invention, when a shelf is set in the refrigerator, the retainer plate with the shelf attached thereto can be inserted into the groove in the inner box, and the claws on both sides of the retainer plate can be inserted into the groove. is pushed by the placement surface of the groove and slides on the groove while being deformed, and then the deformation of the claw portion is released at the position of the recess and the claw portion is fitted into the recess. Thereby, the shelf and the holding plate can be easily set in the refrigerator. In addition, when the shelf and retaining plate are not required or when cleaning the inside of the refrigerator, by pulling the retaining plate firmly toward you, the claws will go over the recesses and the engagement between the claws and the recesses will be prevented. It is released and the holding plate can be removed together with the shelf. As a result, the shelf can be easily removed when creating a wide vertical space or cleaning the interior of the refrigerator without the need for a shelf, improving usability.

(f) Example Embodiments of the present invention will be described below with reference to the drawings.

l is a refrigerator. Reference numeral 2 denotes a heat insulating box body which opens toward the front and is constructed by filling a foamed heat insulating material 5 such as polyurethane between an outer box 3 made of metal and an inner box 4 made of synthetic resin. The inside of the heat insulating box 2 is divided into upper and lower sections by partition walls 6.
The space below the 0 section wall 6, whose upper part is a freezer compartment 7 that is cooled to freezing temperature, is partitioned into three upper and lower compartments by partition plates 8 and 9, and the uppermost part is a refrigerator compartment 10 that is maintained at a refrigerating temperature. The middle chamber is an ice greenhouse 11 that is cooled to an ice-temperate zone, and the lowest chamber is a vegetable compartment 12. Containers 13 and 14 with upward openings are arranged in the ice greenhouse 11 and the vegetable compartment 12 so that they can be freely drawn out. 15.16.17 and 18 are each room 7.10.1
This is a heat insulating door that can open and close doors 1 and 12.

20 is a cooler installed vertically in the cooling chamber 21 behind the back plate 7A of the freezer compartment 7, and a blower 22 is provided above the cooler 2O to suck up cold air that has been heat-converted with the cooler 20. Air blows out from the front air blower lower B into the freezer compartment 7,
The inside of the freezer compartment 7 is cooled to a freezing temperature of about -20°C.

Reference numeral 23 denotes a plurality of grooves formed on both side walls of the inner box 4 in the freezer compartment 7 and the refrigerator compartment 10, and these grooves function as guide rails for supporting the holding plates 25 of the shelves 24, which will be described later. Reference numeral 25 denotes a holding plate that is inserted into each of the grooves 23 so as to be able to be pulled out. As shown in FIGS. 2 and 4, this holding plate 25 is integrally formed with a rib 26 projecting upward on the outer circumferential edge and with tensioning portions 27 on both sides. 24 is a disc-shaped shelf rotatably installed on the holding plate 25. The shelf 24 is rotatably set on a holding plate 25, and set in the inner box 4 by inserting both projecting portions 27 into the grooves 23. here,
On both sides of the protruding portion 27 of the holding plate 25, claw pieces 29 are formed which have arm portions 28 that exert great elasticity during insertion.
