Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator box structure having a rotary door on the upper side and a drawer door on the lower side.

[0002]

2. Description of the Related Art A conventional structure of this type will be described with reference to FIGS. First, in FIG. 9, 31 is the refrigerator body. The main body 31 has a plurality of storage chambers 32, 33, 34, 3 inside.
5 is formed. 36, 37, and 38 are partition walls that partition the chambers, and the front surface of the partition walls also serves as a packing receiving surface of a door, which will be described later.

Next, in FIG. 10, 39, 40 and 41 are doors for closing the front opening portions of the storage chambers 33, 34 and 35. The door 39 is pivotally pivoted with respect to the refrigerator main body 31 with a hinge 42 or the like. 43 is a sealing packing attached to the periphery of the door 39.
The doors 40 and 41 are attached to the refrigerator body 31 so as to be freely drawn out.

A rail 44 is attached to the storage chambers 34 and 35. A frame 45 is attached to the doors 40 and 41. The drawer containers 46 and 47 are suspended on this frame. A movable roller 48 is attached to the tip of the frame 15. The movable roller 48 rolls in the rail 44 as shown in FIG. In other words, when opening and closing the doors 40 and 41,
The movable roller 48 moves in the direction of arrow J in the rail 44.

Reference numeral 49 is a fixed roller. This fixed roller 4
9, the frame 45 is slid as shown in FIG. That is, the vertical positions of the doors 40 and 41 are determined by the positions of the fixed roller 49 and the rail 44. In other words, the vertical positions of the doors 40 and 41 are determined by the mounting position of the reinforcing iron plate to which the fixed roller is mounted and which reinforces the rail 44. The movable roller 48 rolls in the rail 44 and the frame 45 slides on the fixed roller 49, so that the door can be smoothly opened and closed.

Next, referring to FIGS. 11 and 12, the hinge 4 is described.
The mounting structure of No. 2 and the mounting structure of the rail 44 will be described. First, in FIG. 11, 50 is a partition iron plate attached to the front surface of the partition wall 37. This partition iron plate 50 has a door 39,
The packing 43 provided on the 40 side is magnetized. 42 is a hinge that pivots the door 39 so as to be rotatable. 51 is a reinforcement seat. 5
2 is a reinforced iron plate. 53 is an inner box. 54 is a foam insulation material. The reinforcing seat 51 is mounted on the reinforcing iron plate 52 through the inner box 53 with screws 55.
It is stopped and solidified by the foamed heat insulating material 54 so as to be integrated with the inner box 53.

The above-mentioned hinge 42 is attached to this reinforcing seat 51 via a partition iron plate 50. Although not shown in the drawing, the door 39 has a weight of 20 to 30 kg because a beer bottle or the like is stored in the pocket. This weight is hinge 4
It is supported in a cantilevered state by 2. Therefore, a large force is applied to the hinge 42. As a result, the fixing structure of the hinge 42 requires the reinforcing seat 51 and the reinforcing iron plate 52 as described above.

Next, referring to FIGS. 10 to 12, the drawer door 4 is shown.
Explaining the rail fixing structure of 0 and 41 and the drawer door structure, 40 and 41 are drawer doors. A frame 45 that supports the containers 46 and 47 is attached to the doors 40 and 41. Reference numeral 44 is a rail, which is attached to both side walls of the inner box 53 as shown in FIG. 48 is a movable roller. The movable roller 48 is attached to the frame 45 and rolls in the rail 44. Reference numeral 56 is a second reinforcing iron plate attached for the purpose of reinforcing the rail 44 from the foam heat insulating material 54 side. The second reinforcing iron plate 56 is also solidified in the inner box 53 by the foamed heat insulating material 54. Further, the reason for providing the second reinforcing iron plate 56 is that when the doors 40 and 41 are pulled out, the load of the doors 40 and 41 loaded is such that the movable roller 48 causes the rail 44 to move.
Acts as a force to push the arrow in the direction of arrow K (Fig. 10). When the force of the arrow K acts, the rail 44 and the inner box 53 made of synthetic resin cannot withstand the strength.
It will be necessary to supplement this. 49 is a fixed roller. The fixed roller 49 smoothly opens and closes the drawer doors 40 and 41, and when the door 40 is opened, the door 4 is opened.
When a force in the L direction is applied to 0, the movable roller 48
At the same time, the door 40 is prevented from falling in the L direction. For this reason, it is general that the second reinforcing iron plate 56 is used to fix the fixing roller 49 by applying a considerable force to the fixing roller 49. An example of this type of conventional structure is Japanese Utility Model Laid-Open No. 64-16590.

[0009]

The structure described in the above conventional example has the following problems. 1. Since the hinge mounting reinforcing iron plate and the second reinforcing iron plate provided for the rail reinforcement of the drawer door are configured separately, it is difficult to obtain the dimension between the rail and the fixed roller and the hinge that are vertically related, and the packing receiving surface is In securing it, there was a problem that the partition wall could not be thinned.

[0010] 2. Since the second reinforcing iron plate attached to the side wall of the inner box has nothing to do with the partition wall, the dimension between the opposing left and right second reinforcing iron plates changes due to expansion or contraction of the foamed heat insulating material.
Therefore, the frame attached to the drawer door should be designed with some margin. As a result, the width of the container forming the freezer compartment or the like needs to be designed to be small in consideration of the expansion and contraction of the foam insulation material, so that there is a problem that the effective utilization of the storage compartment deteriorates accordingly. It was

3. Since the hinge-attaching reinforcing iron plate and the second reinforcing iron plate for rail reinforcement are provided independently of each other, the loads applied to the doors 10 and 11 are received by the respective reinforcing iron plates alone. For this reason, there is a problem that the second reinforcing iron plate alone cannot receive the load when an abnormality occurs such as a child getting on the drawer door. The present invention aims to solve the above problems.

[0012]

The present invention has been made to achieve the above object. That is, the first purpose is a box body of a refrigerator which has a partition wall for attaching a hinge of a revolving door at an upper part and has a drawer door at a lower part of the revolving door.
The reinforcing iron plate for attaching the partition wall and the rail reinforcing iron plate of the drawer door are integrally formed, and by connecting both ends of the partition wall to the inner box, the dimension between the rail and the fixed roller and the hinge in the vertical direction of the refrigerator. Therefore, the partition wall can be thinned and the packing receiving surface can be surely secured. Also, since the space between the reinforcing iron plates on both sides, which is the reinforcing member, is kept constant by the partition walls, the width between the inner box side walls is also constant, so the storage chamber is designed to be as large as possible without considering variations. It is something that can be done.

A second purpose is to fix a hinge seat for attaching a hinge to a reinforcing iron plate by welding or the like, and to extend the hinge seat to the inside of the refrigerator through a through hole provided in the inner box. Since the hinge seat that fixes the hinge to the reinforcing iron plate that positions the rail and the fixed roller is fixed by welding etc., the rail, fixed roller, and hinge will always move integrally, so the door space Even if the gap size is reduced, the above doors do not collide with each other. At the same time, there is a mounting variation between the reinforcing iron plate and the hinge seat and a hinge seat shift when a load is applied to the hinge. This is to prevent it.

A third object is to fix a hinge seat for attaching a hinge to a reinforcing iron plate by welding or the like, to extend the hinge seat to the inside of the cabinet through a through hole provided in the inner box, and to use the hinge seat. By fixing the non-fixed side of the rail to the partition wall with screws, etc., the rail, fixed roller and hinge 3
Since the person will always move integrally, even if the gap between the doors is reduced, the above doors will not collide with each other, and at the same time, there will be variations in the mounting between the reinforcing iron plate and the hinge seat. It is intended to prevent the hinge seat from being displaced when a load is applied to the hinge, and to prevent the hinge seat from falling toward the front side or the like by utilizing the strength of the partition wall.

The fourth purpose is to fix the fixing roller for assisting the pulling out of the drawer door by using a reinforcing iron plate, thereby increasing the mounting strength of the rail and the fixing roller, and to prevent abnormal force when the door is opened. However, even when it is added to this door, it is prevented that the reinforcing iron plate is upsized so that it is deformed at the mounting portion of the rail and the fixed roller. A fifth object is to further advance the first and second objects described in the above 1, 2 by integrally forming the reinforcing iron plates of the two drawer doors formed on the lower side of the revolving door. is there.

[0016]

With the refrigerator having the above structure, the inside of the storage room can be utilized to the maximum extent. That is, FIGS.
As shown in FIG. 3, the reinforcing iron plate 17 that reinforces the mounting portions of the partition walls 7 and 8, the rail 15 mounting portion, and the fixed roller 18a and 18b mounting portions is assembled to the inner box 16 as shown in FIG. Foam insulation 19 filled between the box 16 and the outer box 20
Generates foaming pressure and foaming heat at the time of filling, but these foaming heat and foaming pressure are protected by the reinforcing iron plate 17 and are not directly applied to the inner box. As a result, it is possible to prevent the inner box 16 from deforming and varying in size.

First, in FIG. 1, 1 is a refrigerator main body. The main body 1 has storage chambers 2, 3, 4, and 5 formed therein. 6, 7 and 8 are partition walls. Next, referring to FIG.
Is a door that closes the front opening of the storage chamber 3. The door 9 is rotatably attached by a hinge 10 attached to the front surface of the partition wall 7. Reference numeral 11 denotes a drawer door, and this door 11 closes the front opening of the storage chamber 4. 12 is a drawer door, and this door 12 closes the front opening of the storage chamber 5. A frame 13 is attached to the doors 11 and 12. 14 is a movable roller.
The movable roller 14 is attached to the frame 13. 1
Rails 5 are attached to both side walls of the inner box 16.

Next, referring to FIG. 3, the partition wall 7 and the rail 1
Describing the reinforcing structure of 5, 7 and 8 are partition walls, 16 is an inner box, and 17 is a reinforcing iron plate. This reinforcing iron plate 17 is a partition wall 7,
8, rails 15a, 15b, fixed rollers 18a, 18
It is a mounting seat for b. That is, the reinforcing iron plate 17 is
As shown in FIG. 3, the partition wall 7 to the rail 15b are made of, for example, one iron plate. The thickness of this iron plate is
A size of 1.6 mm to 2.3 mm is often used. or,
The partition walls 7 and 8 and the rails 15a and 15b are mounted so as to fit into the recesses formed in the inner box 16, and the reinforcing iron plate 17 is formed so as to wrap the recesses just from the foam heat insulating material 19 side. There is. Furthermore, this reinforcing iron plate 17
Is integrally bonded and solidified with the inner box 16, the outer box 20 and the like by the foam heat insulating material 19.

Next, referring to FIGS. 4 and 5, the fixing structure of the partition wall 7 and the hinge mounting structure will be described. 1 is a refrigerator main body and 16 is an inner box. 7 is a partition wall. 7a is the partition wall 7
Front plate made of iron plate that forms the front surface of the. 7b is a hinge seat. 10
Is a hinge. Then, the partition wall 7 (including the hinge seat 7b) is fixed to the reinforcing iron plate 17 by the screw 21 with the screw 21. Further, the hinge 10 attached to the hinge seat 7b is attached to the front plate 7a made of an iron plate as shown in the figure.
A hole 25 is provided on the front side of "a" so as to project.

In FIG. 5, reference numeral 9 denotes a door, which is pivotally attached to the hinge 10. 22 is a packing provided on the contact surface of the doors 9 and 11 with the refrigerator main body 1, 22a is a packing of the door 9, and 22b is a packing of the door 11.
In FIG. 5, the dimension T1 between the packings 22a and 22b.
Is smaller than the size T2 of the mounting portion 10a of the hinge 10. As a result, the width T3 of the partition wall 7 is reduced. In other words, since the mounting portion 10a of the hinge 10 is the hinge seat 7b that abuts against the back side of the front plate 7a, the partition wall 7 can be thinned.

In the refrigerator constructed as described above,
The containers 23 and 24 (FIG. 2) attached to the drawer door are larger than conventional ones for the following reasons. That is, the partition wall 7 mounting portion, the rails 15a and 15b mounting portion, the fixed roller 18
As shown in FIG. 3, the reinforcing iron plate 17 that reinforces the attachment portions a and 18b is assembled to the inner box 16, and then the foam heat insulating material 19 is filled between the inner box 16 and the outer box 20. The foaming pressure and the foaming heat generated when the foam heat insulating material 19 is filled are directly applied to the reinforcing iron plate 17 without being applied to the inner box 16. As a result, the inner box 16 does not deform when the foam heat insulating material 19 is filled, and after filling the foam heat insulating material 19, the foam heat insulating material 19 itself is affected by the ambient temperature and tries to expand or contract. The inner box 16 and the fixed rollers 18a and 18b are protected by the reinforcing iron plate 17, and the amount of deformation thereof is extremely small.

This eliminates the need for considering the deformation of the inner box 16 (expansion and contraction of the foamed heat insulating material 19) in the frame 13 and the containers 23 and 24 attached to the door sides 11 and 12,
The containers 23 and 24 can be designed with the inner box 16 as a reference without causing significant variations in the width direction and the height direction. The reason why the dimensions of the containers 23 and 24 can be obtained in the width direction is that the reinforcing iron plate 17 is positioned because the partition wall 7 is fixed to both side walls of the inner box 16. Further, the reason why the dimensions of the containers 23 and 24 can be obtained in the height direction is, as described above, that the reinforcing iron plate 17 integrally configures the iron plate that reinforces the partition walls 7 and 8 and the iron plate that reinforces the rail 15. Therefore, the dimension in the height direction is determined by the dimension of the reinforcing iron plate 17.

Next, referring to FIGS. 6 and 8, an embodiment different from that shown in FIG. 4 will be described. 17 is a reinforcing iron plate. 7b 'is a hinge seat. The hinge seat 7b 'is fixed to the aforementioned reinforcing iron plate 17 by welding or the like. Of course, in this fixing, positioning of the hinge seat 7b 'poses a problem, so positioning is performed using a gauge or the like. When assembling the reinforcement 26 in which the reinforcing iron plate 17 and the hinge seat 7b ′ are integrated with the inner box 16 before filling the foamed heat insulating material 19, a through hole 27 shown in FIG.
The hinge seat 7b 'of the reinforcement 26 is made to extend to the inside of the refrigerator, and then the reinforcing iron plate portion 17 is fixed to the inner box 16 using a fixing roller or the like. 7c is a mounting portion provided on the hinge seat 7b '. This mounting part 7c
Are attached to the partition wall 7 with screws 28 or the like.

As a result, one of the hinge seats 7b 'is fixed to the reinforcing iron plate 17 and the other is fixed to the partition wall 7. Therefore, when the hinge 10 is attached, the load (upper and lower sides) applied to the hinge 10 is sufficient. , Which is retained. In other words, even if the hinge seat 7b 'is not formed to cover both side walls of the inner box as shown in FIG.
Material cost and weight can be reduced. Other configurations are the same as those described with reference to FIG. 4, and thus description thereof will be omitted.

Next, description will be made with reference to FIG. FIG. 7 shows FIG.
FIG. This FIG. 7 is used in combination with FIG. 6, and shows an example in which the reinforcing iron plates 17 are connected to each other (both sides) only by the partition wall 7. In other words, in FIG. 4, the reinforcing iron plates 17 provided on both side walls are connected by the partition wall 7 and the hinge seat 7b, but FIG. 7 does not have the hinge seat 7b, but only the partition wall 7 is shown. It shows the side that became. This is because the hinge seat 7b has the shape shown in FIG.
