(4) A fixing ring 13 that is fixed to the rotating tray shaft 11a and is slidably fitted into the shaft support hole 12a of the support shelf 12.

  Since the configuration of the refrigerator 100 (see FIGS. 8 to 10) other than the rotating shelf device 10 is a general configuration, a detailed description thereof is omitted. The refrigerator partitions a heat insulating box formed of a steel plate outer box, a resin inner box, and a foam heat insulating material filled between them into a plurality of chambers, and the opening of each chamber can be freely opened and closed. It has a door that closes.

  The heat insulation box of the refrigerator 100 is partitioned into, for example, a refrigerating room 101 (described later), an ice making room, a switching room, a vegetable room, and a freezing room in order from the top. These rooms will be called storage rooms. And these chambers have a refrigerator compartment door body (described later), an ice making compartment door body, a switching compartment door body, a vegetable compartment door body, and a freezer compartment door body that closes the opening in an openable and closable manner.

  The partition member that partitions the heat insulation box into a plurality of chambers includes a first partition member that partitions the refrigeration chamber 101 from the ice making chamber and the switching chamber, a second partition member that partitions the ice making chamber and the switching chamber, an ice making chamber, and switching There is a third partition member that partitions the room and the vegetable compartment, and a fourth partition member that partitions the vegetable compartment and the freezer compartment.

  First, the basic configuration of the rotating shelf device 10 will be described with reference to FIGS. 2 to 7 are diagrams showing the first embodiment, FIG. 2 is a conceptual plan view at the original position of the rotating shelf device 10, FIG. 3 is a conceptual perspective view at the original position of the rotating shelf device 10, and FIG. FIG. 5 is a conceptual perspective view of the rotary shelf device 10 at the forward rotational position, FIG. 6 is a conceptual perspective view of the rotary shelf device 10 at the forward rotational position, and FIG. It is a conceptual perspective view in an original position rotation position.

  A pair of rails 20 (guides for guiding the support shelf 12 in the front-rear direction) in the figure are provided on both side walls of the storage chamber in the refrigerator (both side wall surfaces of the inner box) so that the support shelf 12 can slide in the front-rear direction. I support it. A rotation tray 11 is provided on the support shelf 12, and the support shelf 12 and the rotation tray 11 are connected to each other by one fulcrum that can freely rotate (this will be described later). The rotating tray 11 is supported on a support shelf 12 by a freely rotatable fulcrum, and the four corners of the rotating tray 11 have a shape that can be rotated by having a notch with an arc shape centering on the rotating fulcrum.

  In the original position shown in FIGS. 2 and 3, the rotating shelf device 10 is stored in a storage room (for example, a refrigerator room) in the refrigerator without the rotating tray 11 rotating. And the support shelf 12 which can slide along the rail 20 in the front-back direction is located in the innermost part of a store room. At this time, the user can slide the support shelf 12 back and forth along the rail 20 as necessary. 2 and 3 show a state in which the food 30 is placed in the rightmost innermost portion of the rotating tray 11.

  For example, as shown in FIG. 4, food (not shown) can be easily put in and out of the front or near the center of the rotary tray 11 by pulling the rotary tray 11 forward along the rail 20. it can.

  However, for example, the food 30 placed in the rightmost innermost part of the rotating tray 11 is difficult to easily take out even if the rotating tray 11 is pulled forward along the rail 20 as shown in FIG. . This is particularly difficult when there is another food on the front side of the food 30 placed in the rightmost innermost part of the rotating tray 11.

  In the rotating shelf device 10 of the present embodiment, the rotating tray 11 is supported on the support shelf 12 by a freely rotating fulcrum, and the four corners of the rotating tray 11 have a notch with a circular arc shape around the rotating fulcrum. It has a shape that can be rotated. Therefore, for example, when taking out the food 30 placed in the rightmost innermost part of the rotating tray 11, the rotating tray 11 in the innermost part is first pulled out (the state of FIG. 4). Next, as shown in FIG. 5, the rotating tray 11 is rotated in either direction (which may be clockwise or counterclockwise, FIG. 5 shows a clockwise direction).

  FIG. 6 shows a state rotated 180 ° from the original position shown in FIGS. The front-rear positional relationship of the food placed on the rotating tray 11 can be reversed in a state where the rotating tray 11 at the innermost part is pulled forward (FIG. 4).

  In particular, the food 30 placed in the rightmost innermost part of the rotating tray 11 at the original position shown in FIGS. 2 and 3 is positioned in the frontmost row of the rotating tray 11. Therefore, the user can take out the food 30 easily.

  Furthermore, as shown in FIG. 7 in that state (the food 30 is located in the foremost row of the rotating tray 11), the support shelf 12 can be moved rearward and stored in the innermost part of the storage chamber. It is also possible to store refrigerated foods stored in the deepest part of the refrigerator where the expiration date tends to approach in the front space of the refrigerator. In addition to user convenience, the expiration date of the food It can also be effective in reducing loss.

  Up to this point, the case of taking out the food 30 placed in the rightmost innermost part of the rotating tray 11 has been described. On the other hand, for example, there is a storage space in the innermost right part of the rotating tray 11, and the food is there. The same procedure can be used when storing the like.

  In addition, when there are a plurality of shelves in the storage room located at the uppermost part of the refrigerator, the use of the rotating shelf device 10 of the present embodiment for the uppermost shelf improves the take-out property of the food in the back of the uppermost shelf. This is particularly effective.

  When the support shelf 12 of the rotating shelf device 10 is pulled out to the front, and the rotating tray 11 is rotated about 90 ° from the original position, and the linear portion (longitudinal direction) of the rotating tray 11 is substantially in the front-rear direction, If the door of the opened refrigerator 100 is closed by mistake, the rotating tray 11 may interfere with a bin container or the like stored in a pocket (to be described later) provided on the door of the refrigerator 100 and the bin container or the like may be damaged. .

  In such a case, the refrigerator 100 according to the present embodiment prevents a bottle container or the like housed in the door pocket from being damaged by bringing a pocket provided in the door into contact with the rotating tray 11.

  8 to 11 are diagrams showing the first embodiment, FIG. 8 is a partial longitudinal sectional view of the refrigerator 100, FIG. 9 is a transverse sectional view of the refrigerator 100 in a state where the door is closed, and FIG. A cross-sectional view of the refrigerator 100 with the tray 11 rotated by about 90 °, FIG. 11 is a side view of the rail 20 viewed from the refrigerator compartment 101 side.

  A configuration of the refrigerator compartment 101 located at the top of the refrigerator 100 will be described as an example of a storage compartment (FIGS. 8 and 9). The refrigerator compartment 101 has an opening at the front, and is provided with a rotary door (left) 50a and a door (right) 50b (door body, door-to-door) that opens and closes the opening. The door (left) 50a is provided with a pocket (left) 60a for storing a bottle container or the like inside. The door (right) 50b is provided with a pocket (right) 60b for storing a bottle container or the like inside. The lateral width of the door (left) 50a and the door (right) 50b is larger in the door (right) 50b than in the door (left) 50a, but this is only an example and may be arbitrary.

  The positional relationship in the height direction between the pocket (left) 60a and the pocket (right) 60b and the rotating tray 11 of the rotating shelf device 10 will be described. In the refrigerator 100 of the present embodiment, the door (left) 50a and the door (right) 50b are opened (about 90 °) and the rotating tray 11 is rotated about 90 ° from the original position (see FIG. 10). When the (left) 50a or the door (right) 50b is closed, the pocket (left) 60a or the pocket (right) 60b is configured to come into contact with the rotating tray 11.

An essential configuration for this purpose will be described with reference to FIG.
(1) The upper end of the end portion of the rotating tray 11 cut out in an arc shape is higher than the bottom surfaces of the pocket (left) 60a and the pocket (right) 60b;
(2) The lower end of the end portion of the rotating tray 11 that is cut out in an arc is lower than the upper ends of the pocket (left) 60a and the pocket (right) 60b;
By satisfying the above conditions (1) and (2), the door (left) 50a and the door (right) 50b are opened (about 90 °) and the rotating tray 11 is rotated about 90 ° from the original position (see FIG. 10), when the door (left) 50a or the door (right) 50b is closed, the pocket (left) 60a or the pocket (right) 60b comes into contact with the end portion of the rotating tray 11 cut out in an arc shape.

  From the state in which the door (left) 50a and the door (right) 50b in FIG. 9 are closed, the door (left) 50a and the door (right) 50b are released, and then the support shelf 12 moves forward on the rail 20, Accordingly, the rotating tray shaft 11 a (FIG. 1) of the rotating tray 11 also moves forward, and the rotating tray 11 can rotate without interfering with the back surface of the refrigerator compartment 101. The rail 20 is provided with a stopper 20a that abuts the support shelf 12 and regulates the amount of forward movement, so that the rotating shelf device 10 does not fall forward (see FIG. 11).

  The support shelf 12 moves forward, and the rotating tray 11 can be rotated to be in the state shown in FIG. However, in the state of FIG. 10, as shown in the figure, the rotating tray 11 rotates about 90 ° from the original position (FIGS. 2 and 3), and when the door (left) 50a and the door (right) 50b are closed, This interferes with the pocket (left) 60a and the pocket (right) 60b itself or the bottle container in the pocket (left) 60a and the pocket (right) 60b.

  However, in the refrigerator 100 of the present embodiment, as shown in FIG. 8, the rotating tray 11, the pocket (left) 60a, and the pocket (right) 60b are in a positional relationship of being wrapped in the height direction. Therefore, from the state where the user stops the rotating tray 11 at a position where the pocket (left) 60a or the pocket (right) 60b interferes (a state rotated about 90 ° from the original position), the door (door (left ) Even if 50a or the door (right) 50b) is closed, the pocket (left) 60a or the pocket (right) 60b comes into contact with the end of the rotating tray 11 that is cut out in an arc shape. Therefore, the articles in the pocket (left) 60a, the pocket (right) 60b, and the rotating tray 11 are not directly impacted. Accordingly, the risk of dropping the article (food) can be reduced, and for example, many bottle containers and the like are stored in the pocket (left) 60a and the pocket (right) 60b, but breakage of the bottle container can also be avoided.

  As described above, the rotating shelf device 10 according to the present embodiment includes the rotating tray 11 on which food or the like is placed, the supporting shelf 12 that rotatably supports the rotating tray 11, the rotating tray 11 and the supporting shelf 12. A fixing ring 13 to be fitted and a pair of rails 20 that are installed on the left and right side surfaces of the storage chamber and on which the support shelf 12 slides, and a rotation center for rotating the rotation tray 11 is formed at a substantially center of the support shelf 12. In addition, since the rotating tray 11 has a substantially quadrangular shape in which the four corners of the rotating tray 11 are cut out by an arc shape centered on the rotation fulcrum, the effect of minimizing the invalid space in the corner portion can be achieved. Play.

  Moreover, as an arrangement positional relationship in the height direction, pockets (pocket (left) 60a and pocket (right) 60b) installed on the front doors (door (left) 50a and door (right) 50b) of the rotating shelf device 10 are provided. The positional relationship is such that the flange at the end notched in the arc shape of the rotating tray 11 is within the flange height range. Thereby, when the rotating tray 11 is rotated, the rotating tray shaft 11a moves forward, so that when the door (door (left) 50a and door (right) 50b) is closed, the pocket (pocket (left) 60a and The rotating tray 11 passes through a locus that interferes with the pocket (right) 60b) itself or a bottle container in the pocket. However, even if the user accidentally closes the door from the state where the rotating tray 11 is stopped at the pocket interference position, the flange and the rotating tray of the pocket (pocket (left) 60a and pocket (right) 60b) 11, the flanges at the ends of the arcuate notch are in contact with each other, so that the articles in the pockets (pocket (left) 60 a and pocket (right) 60 b) and the rotating tray 11 are not directly impacted. Therefore, the risk of dropping articles can be reduced, and, for example, many bottles and the like are stored in the pockets (pocket (left) 60a and pocket (right) 60b). Play.
