Description

  The present invention relates to a refrigerator, and more particularly to a refrigerator provided with a storage container that can move back and forth in a refrigerated room.

The refrigerator is equipped with a refrigerator room having the highest frequency of use at the top. The refrigerator compartment is provided with a plurality of partition plates, and a space forming the refrigerator compartment is partitioned by the partition plates. A refrigerator including a storage container that is movable in the front-rear direction above the partition plate is also known (see Patent Documents 1 and 2). The storage container moves back and forth in the front-rear direction, that is, between the door side covering the refrigerator compartment and the rear wall side. Such a storage container needs to be supported while being guided so as to be movable in the front-rear direction. Therefore, in the storage disclosed in Patent Document 1, a pulley is provided at the bottom of the storage container, and the pulley moves the rail portion provided on the partition plate, thereby guiding the movement of the storage container and the storage container. Support is intended. On the other hand, in Patent Document 2, the storage container is moved and supported by supporting the bottom portion with a sliding member while supporting both ends in the width direction of the storage container.
JP 2000-46465 A JP 2005-69601 A

However, in the case of Patent Document 1 or Patent Document 2, if the entire length in the width direction of the storage container is extended, the bottom of the storage container is likely to be deformed. In particular, as in Patent Document 2, when supporting both ends in the width direction of the storage container, the deformation of the bottom increases as the width of the storage container increases.
On the other hand, by providing a pulley between the storage container and the partition plate as in Patent Document 1, deformation of the bottom of the storage container is reduced. However, since the pulley provided at the bottom of the storage container presses the partition plate, there is a problem that the partition plate is deformed even if the deformation of the storage container is reduced. Further, in order to reduce interference with the partition plate due to deformation of the storage container, a space is required between the storage container and the partition plate. However, the space between the storage container and the partition plate becomes a so-called dead space in which food or the like cannot be stored, causing a problem that the capacity of the refrigerator compartment is reduced.

  Therefore, the present invention has been made in view of the above problems, and the object thereof is to provide a storage container and a partition plate without causing a decrease in the capacity of the refrigerating chamber even if the overall length in the width direction of the storage container is extended. It is in providing the refrigerator which reduces the deformation | transformation of the.

  In order to achieve the above object, in the refrigerator of the present invention, the refrigerator is provided with a drawer-type storage container that is movable in the front-rear direction, provided in the refrigerator compartment, and the refrigerator compartment is divided vertically. And a partition plate on which the storage container is placed, and a space formed below the partition plate, and extends in the front-rear direction parallel to the moving direction of the storage container to extend the partition plate from below. A vertical partition member to be supported, and a guide member that is provided on the partition plate side at the bottom of the storage container, contacts the partition plate above the vertical partition member, and guides the movement of the storage container when the storage container moves. And.

  According to the present invention, the vertical partition member supports the partition plate from below. The guide part for guiding the movement of the storage container is located above the vertical partition member. Therefore, even if force is applied to the partition plate from the guide portion of the storage container, the force is received by the vertical partition member provided below the partition plate. As a result, the storage container is supported by the guide portion, and the partition plate is supported by the vertical partition member. Further, since the deformation of the storage container is reduced, the space to be secured between the storage container and the partition plate is also reduced. Therefore, even if the full length in the width direction of the storage container is extended, the deformation of the storage container and the partition plate can be reduced without causing a reduction in the capacity of the refrigerator.

Hereinafter, refrigerators according to a plurality of embodiments of the present invention will be described with reference to the drawings. Note that, in a plurality of embodiments, substantially the same components are denoted by the same reference numerals, and description thereof is omitted.
(First embodiment)
The refrigerator according to the first embodiment of the present invention is shown in FIGS. In the refrigerator 10, a refrigerator body 11 is formed in a refrigerator body 11 as a storage room, an ice making room 13 and a switching room 14 provided on the left and right sides, and a freezing room 15 in order from above. The refrigerator main body 11 is comprised from the outer box made from a steel plate, the inner box made from resin, and the heat insulating material with which these were filled. By insulating and partitioning the inside of the inner box, the refrigerator compartment 12, the ice making chamber 13, the switching chamber 14, and the freezer compartment 15 are formed in the inner box.

  The refrigerator compartment 12 is closed with a double door 16 as shown in FIG. The ice making chamber 13, the switching chamber 14, and the freezing chamber 15 each house a drawer-type container, and are closed by doors 17, 18, and 19 that constitute the front portion of the container. Thus, the refrigerator 10 has the doors 16, 17, 18, and 19 on the front side. The door 16 is provided with a push-type door operation unit 20. By pushing in the door operation unit 20, the door 16 is pushed forward by a solenoid (not shown), and the door 16 is automatically opened. The door 16 can be opened and closed manually.

  FIG. 2 is a perspective view of the refrigerator 10 with the door 16 of the refrigerator 10 removed and the side wall of the refrigerator compartment 12 broken away. A plurality of shelves 21 are arranged in the refrigerator compartment 12. A storage container 30 is disposed below the shelf 21 of the refrigerator compartment 12. The storage container 30 is accommodated in the refrigerator compartment 12, and is provided so that the movement to the front-back direction of the refrigerator 10 is possible. That is, the storage container 30 can be pulled out from the refrigerator compartment 12. A chilled container 22 is provided below the storage container 30 with a partition plate 40 interposed therebetween. The chilled container 22 can also be pulled out in the front-rear direction of the refrigerator 10. A water supply tank 23 for an automatic ice making device is disposed on the side of the chilled container 22.

  The partition plate 40 extends in the width direction of the refrigerating chamber 12, that is, in the left-right direction in FIG. 1 to partition the refrigerating chamber 12. A storage container 30 is placed above the partition plate 40, and a chilled container 22 and a water supply tank 23 are provided below the partition plate 40. A vertical partition member 41 is provided below the partition plate 40 and between the chilled container 22 and the water supply tank 23. The vertical partition member 41 supports the partition plate 40 from below and partitions the space partitioned below the partition plate 40 into two. Thereby, the chilled container 22 is accommodated in one space below the partition plate 40, and the water supply tank 23 is accommodated in the other space. Each member accommodated in the refrigerator compartment 12, such as the storage container 30, the partition plate 40, the vertical partition member 41, the chilled container 22, and the water supply tank 23, is formed of resin.

  As shown in FIGS. 1 and 4, the partition plate 40 has rail grooves 42 between both ends in the width direction. The rail groove 42 is formed to be recessed from the storage container 30 side of the partition plate 40 to the opposite side, that is, downward. As shown in FIG. 5, the rail groove 42 linearly extends from the front end of the partition plate 40, that is, the end on the door side, to the rear end, that is, the rear wall side of the refrigerator 10. A vertical partition member 41 is disposed below the rail groove 42. Therefore, the partition plate 40 is supported by the vertical partition member 41 from below the rail groove 42.

  As shown in FIGS. 1 and 2, the storage container 30 is open at the top. The storage container 30 has a bottom 31 on the side opposite to the upper opening. The bottom 31 is provided substantially in parallel with the partition plate 40. The storage container 30 also has side walls 32 that rise upward from the bottom 31 substantially vertically at both ends in the width direction. As shown in FIG. 1, the storage container 30 has a support portion 33 outside the side wall 32. The support portion 33 is attached to a slide rail 34 attached to the inner side of the inner box that forms the refrigerator compartment 12. The slide rail 34 supports the storage container 30 at both ends in the width direction of the refrigerator compartment 12. The slide rail 34 extends in the front-rear direction of the refrigerator 10. The support part 33 is movable back and forth along the slide rail 34. As the support portion 33 moves on the slide rail 34, the storage container 30 can be moved back and forth inside the refrigerator compartment 12.

  As shown in FIGS. 1 and 4, the bottom portion 31 has a guide portion 35 on the partition plate 40 side, that is, on the side opposite to the opening. The guide part 35 is provided on the partition plate 40 side of the bottom part 31 and has a roller 36 as a guide member fitted in the rail groove 42 as shown in FIG. The roller 36 is rotatably supported on the bottom 31 of the storage container 30. The roller 36 moves back and forth while being guided by the rail groove 42 by rotating in the rail groove 42. The roller shaft 37 is rotatably supported by a shaft support portion 38 that protrudes from the bottom portion 31 toward the partition plate 40 side. Thereby, the roller 36 moves while rotating the rail groove 42 by the movement of the storage container 30.

  As shown in FIG. 6, the guide portion 35 including the roller 36 is provided on the rear end side from the center in the front-rear direction of the storage container 30. Further, when the storage container 30 is moved to the foremost position as shown in FIG. 6, the guide portion 35 is located behind the front end of the partition plate 40. Therefore, even if the storage container 30 is moved to the forefront, the guide portion 35 does not fall off the rail groove 42 of the partition plate 40.

  When the storage container 30 is supported by the slide rail 34 at both ends in the width direction, the bottom 31 of the storage container 30 is deformed by the weight of food stored in the storage container 30. The deformation of the bottom 31 is mainly caused by bending toward the partition plate 40 at the intermediate portion in the width direction of the storage container 30. In the first embodiment, the roller 36 of the guide portion 35 is provided between both end portions of the bottom portion 31 in the width direction. As a result, when both ends of the storage container 30 are supported, the bottom 31 is supported by the roller 36 in the middle in the width direction of the storage container 30 where deformation is increased. As a result, the deformation of the bottom 31 of the storage container 30 is reduced.

  On the other hand, the roller 36 is provided corresponding to the rail groove 42 of the partition plate 40. When the roller 36 is provided in the storage container 30, the rail groove 42 of the partition plate 40 receives force from the storage container 30 via the roller 36. In the case of the first embodiment, the partition plate 40 is supported by the vertical partition member 41 in the middle in the width direction. The vertical partition member 41 is provided below the rail groove 42. Therefore, even if a force is applied from the roller 36 to the rail groove 42 of the partition plate 40 due to the weight of the storage container 30, the partition plate 40 is supported from below by the vertical partition member 41. Therefore, deformation of not only the bottom 31 of the storage container 30 but also the partition plate 40 is reduced.

  In the storage container 30, a net shelf 50 as a detachable shelf is placed on one side wall 32, in this embodiment, the left side wall 32 when viewed from the front. In the case of this embodiment, the net shelf 50 is arranged from the center to the end in the width direction of the storage container 30. That is, as shown in FIG. 1, when the refrigerator compartment 12 is viewed from the front, the net shelf 50 is arranged on the left side of the center. In this case, the center of gravity of the storage container 30 in the width direction is located on the left end side from the center. Therefore, in the present embodiment, the guide portion 35 is arranged on the left end side of the bottom portion 31 with respect to the center in the width direction in consideration of the center of gravity due to the arrangement of the net shelf 50. Thereby, the storage container 30 is supported by the guide part 35 according to the position of the center of gravity. In addition, although the net shelf 50 was demonstrated to the example as a desorption shelf, not only the net shelf 50 but arbitrary containers and shelves may be applied.

According to the first embodiment having the above configuration, the following effects can be obtained.
The bottom 31 of the storage container 30 is supported by the roller 36, and the lower part of the rail groove 42 of the partition plate 40 in contact with the roller 36 is supported by the vertical partition member 41. Thereby, the deformation of the bottom 31 of the storage container 30 is reduced by the roller 36, and the deformation of the partition plate 41 receiving the force from the roller 36 is reduced by the vertical partition member 41. Therefore, even when the storage container 30 is expanded in the width direction of the refrigerator compartment 12 and both ends in the width direction are supported, the deformation of the storage container 30 and the partition plate 40 can be reduced. Therefore, the storage container 30 can be moved easily.

  By reducing the deformation of the bottom 31 of the storage container 30, interference between the bottom 31 of the storage container 30 and the partition plate 40 is reduced. Therefore, the distance between the bottom 31 and the partition plate 40 can be reduced. The rail groove 42 is recessed downward from the partition plate 40, but a vertical partition member 41 is disposed below the rail groove 42. Therefore, even if the rail groove 42 is recessed, only the height of the vertical partition member 41 is reduced, and the space below the partition plate 40 is not reduced. As a result, interference between the storage container 30 and the partition plate 40 can be avoided without securing an unnecessary space between the storage container 30 and the partition plate 40, and the partition plate 40 can be formed even if the rail groove 42 is formed. The space formed below the space is not reduced. Therefore, the storage container 30 can be smoothly moved without reducing the volume of the refrigerator compartment 12.

The roller 36 provided at the bottom 31 of the storage container 30 is provided on the rear side of the middle in the front-rear direction. Therefore, even if the storage container 30 is pulled out to the foremost side of the refrigerator 10, the roller 36 does not fall off from the rail groove 42 of the partition plate 40. Therefore, the storage container 30 can be moved smoothly, and the storage container 30 can be prevented from falling off the partition plate 40.
When the net shelf 50 is provided on one of the side walls of the storage container 30, the guide portion 35 is disposed closer to the net shelf 50 than the center in the width direction of the storage container 30. Thereby, even if the gravity center position of the storage container 30 changes by the net shelf 50, the guide part 35 supports the storage container 30 in the vicinity of the gravity center position. Therefore, the deformation of the storage container 30 can be further reduced, and the storage container 30 can be smoothly moved.

(Second Embodiment)
The storage container of the refrigerator by 2nd Embodiment of this invention is shown in FIG.
In the second embodiment, the guide part 35 has a sliding part 39 instead of the roller 36. The sliding part 39 protrudes from the bottom part 31 of the storage container 30 to the partition plate 40 side. The sliding portion 39 may be formed integrally with the bottom portion 31 of the storage container 30 or may be formed separately and fixed to the bottom portion 31. The sliding portion 39 is fitted in the rail groove 42 of the partition plate 40 and slides with at least one of the upper end surface and the side end surface of the partition plate 40 forming the rail groove 42. A member made of a material having a small frictional resistance such as polytetrafluoroethylene may be attached to the sliding portion 39 and the rail groove 42. Further, a lubricant such as liquid silicon may be applied to the inside of the rail groove 42.

In the second embodiment, the following effects are obtained in addition to the effects of the first embodiment.
By providing the sliding part 39 as the guide part 35, the structure can be simplified and the number of parts can be reduced as compared with the roller 36 of the first embodiment. In addition, smooth movement of the storage container 30 can be ensured with a simple structure by using a material having a small frictional resistance for at least one of the sliding portion 39 and the rail groove 42 or applying a lubricant.
