  Moreover, the both sides | surfaces of the partition wall 26 have the opening part 26a, and the partition wall 26 is filled with the foam heat insulating material 22 similarly to the heat insulation box 19. FIG.

  The vegetable compartment 27 and the freezer compartment 28 are respectively closed at the front opening 19a by a vegetable compartment door 29 and a freezer compartment door 30, and the vegetable compartment 27, the vegetable compartment door 29, the freezer compartment 28, and the freezer compartment door 30 are respectively. By being connected by the rail member 31, it can be drawn and slid in the front-rear direction.

  In addition, the container 33 of each storage room is moved in synchronization with the door support member 37 being disposed and fixed on the moving rail 31b after the rail member 31 is mounted in the storage, The container 33 is detachable upward when each storage chamber is at least fully opened.

  The reinforcing member 32 is a position restricting means for the rail member 31. The reinforcing member 32 is provided on both sides of the storage chamber from the front opening 19 a that allows the rail member 31 to slide in the front-rear direction, and is fixed to the fixed rail 31 a of the rail member 31. Yes. Further, the reinforcing member 32 is fixed to the inner box 20 with a distance of 10 mm or more from the vacuum heat insulating material 21 a and embedded in the foam heat insulating material 22.

  The rail member 31 includes a fixed rail 31a, a moving rail 31b in which a door support member 37 is disposed and fixed, an intermediate traveling rail 31c provided between the fixed rail 31a and the moving rail 31b, an intermediate traveling rail 31c, and a fixed rail. It consists of a plurality of bearings 31d which are rotation support members that support the engagement between 31a and the moving rail 31b.

  In addition, the rail member 31 which has the fixed rail 31a, the moving rail 31b, and the intermediate | middle traveling rail 31c arrange | positioned via the bearing 31d between the fixed rail 31a and the moving rail 31b was fixed in the state assembled previously. The position of the fixed rail 31a is fixed by the reinforcing member 32, and the clearance between the rails can be set to a minimum.

  Further, by providing the door reinforcement member 36 for attaching the door support member 37 on the foam insulation side of the storage room door, the fixed movement rail 31b is stabilized, and the position regulation of the rail member 31 is further ensured. Become.

  The reinforcing member 32 is independently regulated in position with the fixed rail 31a of the rail member 31, and is composed of a material whose linear expansion coefficient is 1.0 to 3.0 × 10 −6 cm / cm · ° C. Yes.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when each storage room door is pulled out, the moving rail 31b of the rail member 31 and the intermediate traveling rail 31c provided on both sides of each storage room are smoothly slid toward the front side as the rotation support member 31d rotates. Move.

  Along with this, the container 32 supported by the door support member 37 disposed on the rail member 31 is also pulled out to the front, so that the object to be cooled stored in the container 33 can be taken out and a new object to be cooled can be stored. .

  As described above, in the present embodiment, the clearance between the fixed rail 31a and the movable rail 31b can be reduced by fixing the rail member 31 in a state in which the fixed rail 31a and the movable rail 31b are pre-assembled to both side walls. It is possible to configure a high-quality drawer with little play. Further, since the variation in mounting can be reduced by reducing the clearance, it is possible to suppress the appearance failure such as the inclination due to the door mounting failure and the non-uniform feeling with other doors. Moreover, even when a load is applied to the container 33 by supporting the fixed rail 31a and the moving rail 31b with a bearing 31d which is a rotation support member, the moving rail 31b can move smoothly, thereby reducing the operation force of the drawer. Can improve usability.

  Further, by restricting the mounting position of the fixed rail 31a of the rail member 31 by the reinforcing member 32, the width dimension or parallelism of the pair of left and right rail members 31 can be maintained as prescribed, and the reinforcing member 32 is provided with the vacuum heat insulating material 21a. It is possible to suppress dimensional changes due to thermal shrinkage during cooling after the foamed heat insulating material 22 is filled in the heat insulating box body 19 in which is disposed. Further, even when the rail member 31 having a small clearance between the fixed rail 31a and the movable rail 31b is fixed in advance to the fixing portions on both side surfaces with the rail member 31 assembled in advance, the dimensional system between the pair of left and right rail members 31 can be kept high. The operability at the time of pulling out the container 33 can be enhanced by the reinforcing member 32 which is a position restricting means. In addition, operability and reliability can be ensured over a long period of time.

  In addition, by providing the intermediate rail 31c, it is possible to increase the pull-out allowance of the moving rail 31b of the rail member 31 and to draw out to the back of the container 33. It is possible to prevent loss due to forgetting to use the cooling object and to easily remove the container 33 and to improve usability.

  Further, since the reinforcing member 32 in which the position of the left and right fixed rails 31a is regulated is embedded in the foam heat insulating material 22 of the heat insulating box 19 provided with the vacuum heat insulating material 21a, condensation and frost formation may occur when the refrigerator 18 is used. In addition, since it does not come into contact with air, the structure is excellent in corrosion resistance and inexpensive. Moreover, since it is set as the heat insulation box which arrange | positioned the vacuum heat insulating material 21a, it is hard to be influenced by the heat absorption from external air, and can aim at the energy saving effect. Furthermore, by applying a vacuum heat insulating material 21a having higher compressive strength and bending strength than the foam heat insulating material 22, the sliding door sliding property can be enhanced while increasing the structural strength of the heat insulating box itself.

  Further, the reinforcing member 32 for regulating the position of the fixed rail 31a secures a distance of 10 mm or more from the vacuum heat insulating material 21a, so that the fluidity of the foam heat insulating material 22 can be secured and the heat insulating box body 19 having a predetermined heat insulating performance can be secured. Can be provided.

  Further, since the reinforcing member 32 independently regulates the position of the fixed rail 31a of the rail member 31, there is no heat leak due to heat transfer from each storage chamber, which contributes to energy saving and can be reduced in size and cost. You can also.

  Further, the linear expansion coefficient of the reinforcing member 32 is set to 1.0 to 3.0 × 10 −6 cm / cm · ° C., and the operation reliability of the rail member 31 is improved by suppressing the influence caused by the shrinkage during the operation of the refrigerator 18. can do.

  As described above, the refrigerator according to the present invention is small in play, can open and close smoothly even when a load is applied to the container, and has a high-quality and easy-to-use drawer storage. It can also be applied to applications such as a cooling storage drawer.
