Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention has container attachments on the top and bottom that slide on rails provided on the inside of the refrigerator and can be freely drawn out. This invention relates to a refrigerator equipped with sealing packing on the lower edge of the door and the upper part of the lower door.

[Background of the invention]

Conventional refrigerators of this type usually have a ridge-shaped partition frame located on the same plane as the front opening surface of the refrigerator body.
This was the contact surface between the lower edge packing of the upper door and the upper edge packing of the lower door. For this reason, the container that is attached to the above-I must be dimensioned to avoid this partition frame, which reduces the height of the container itself, and also prevents the partition frame from getting in the way when taking out items stored in the container. There was a flaw.

In addition, for those related to this type of refrigerator, for example,
There is a publication No.-1190.

[Purpose of the invention]

In order to improve the above-mentioned defects, the present invention removes the conventional partition frame from a refrigerator with a door equipped with pull-out containers at the top and bottom.

[Summary of the invention]

That is, the present invention has container parts i on the top and bottom that can be freely pulled out by sliding on rails provided inside the refrigerator, and a seal is provided on the lower edge of the adjacent upper door and the upper edge of the door. In a refrigerator equipped with packing, the door with the container comes into contact with the sealing packing in the stored state, and the opening/closing operation is smooth when the door is pulled out or when the door is closed.

[Embodiments of the invention]

Hereinafter, details of the present invention will be explained with reference to an embodiment shown in FIGS. 1 to 4. Reference numeral 1 denotes a refrigerator main body, this main body 1 has an outer panel 2 on the outside, a refrigerator compartment 3 inside, and a freezer compartment interior. 16 is formed. The interior of the refrigerator compartment 3 and the interior of the freezer compartment 16 are separated by a partition 13.

5.6.7.8.9 are 's1, second, third, fourth, and fifth holes that close the front opening of the refrigerator compartment main body. Each - indicates a food storage container 5a, 6a, 7, either integrally or separately.
a, 8a, and 9a.

Each container has a plurality of rollers 4 that move on the inside rail 3a. 14 is the lower edge packing of h5, and 15 is the upper edge packing of the door 6, both of which are configured to be in close contact with the front surface of the partition 13 described above. f16.
The lower edge of 7.8 and the upper edge of non-7, old, and 9 are between n6 and 7 in order to seal between the adjacent doors of that door.
On the inner side of the refrigerator between 7 and 8 and between doors 8 and 9, there is no partition like the above-mentioned inner partition 13 or a pasted partition frame that has been used conventionally. If we explain the sealed structure between the doors using an enlarged view (Figures 2 to 4) between b8 and b9 as a representative example, f! Soft seal packing 10 on the lower edge of 8
The mounting claw 8b of the door and the mounting claw 10 of the seal packing 10
It is equipped with b.

A hard seal packing 12 is provided on the upper edge of the door 9 located below the opening 8, and by contacting with the seal packing 10 described above, the gap between f18 and 9 is provided.

It's sealed. 12a is a magnetic material built into the hard seal packing 12, which brings the magnet 10a built into the seal packing 10 into close contact with the magnet 10a to improve the sealing performance of the seal packings 10 and 12. The contact surface 10c of the seal packings 10 and 12 is coated with a lubricant containing, for example, fluorine, to reduce friction during close contact. The seal packing 12 that comes into contact with the soft seal packing IO is made of a lubricating hard plastic filled with fluorine-based or fluorine-based resin in order to reduce the opening/closing resistance of the door due to friction when they are in close contact with each other. There is. Also, the gap G8 between doors 8 and 9 is
Due to the manufacturing technology of parts and assemblies, the size of the gap may vary slightly, so the seal packing 10 is made of flexible soft plastic to accommodate changes in the gap G8. 12e is door 9
In consideration of the case where the door n8 which was in the open state closes when the door is not closed, and also taking into account the hanging of the seal packing 10 and the change in the gap G8 mentioned above, the storage is installed so as not to collide with the seal packing 10. This is a guide section that slopes outward. 1
Similarly, 2b is written when closing the door from a fraud 9 or an open state.B8
The guide portion is inclined toward the inner side of the refrigerator so as not to collide with the seal packing 10, taking into consideration the case where the seal packing 10 is in a closed state, and taking into consideration the hanging of the seal packing 10 and the change in the gap G8. Note that 12f inside the seal packing 12 is filled with a heat insulating material such as urethane to prevent condensation from occurring on the inside of the refrigerator due to heat conduction of the hard packing 12 itself. 12g is an intrusion passage for the urethane heat insulating material during foaming, provided on the side of the 7 langes 9e on the inner side of the chamber, and the heat insulating material 17, such as urethane, foamed into the inside 19 through the passage 12g,
After being filled into the inner space 12f of the seal packing, the urethane is cured, so that the seal packing 12 is more firmly fixed to the seal 9 due to the adhesive force of the urethane itself. Reference numeral 11 denotes a corner seal, and for the inclined guide portion 12b of the seal packing 12 described above, the front surface 7 of the outer panel has a flange 2a,
It soles the abbreviated gap formed between the seal packings 10 and 12.

〔Effect of the invention〕

As explained above, in the present invention, the sealing packing at the lower edge of the upper door is made soft, and the sealing packing at the upper edge of the lower door which contacts the sealing packing is made hard T, so that resistance due to dIk friction when they abut against each other is made This reduces the number of doors, making it easier to open and close the pull-out door, and the soft and hard sole improves the airtightness between the doors, making it possible to remove the partition frame that was previously used. be. In addition, because the soft seal packing is coated with a low-friction agent and the hard seal packing is made of a low-friction material, even if the contact force for close contact with the drawer-type seal packing is increased,
Since the door can be easily opened and closed, and the twisting force applied to the soft seal packing when opening and closing the egg is reduced, a seal structure that can be used safely for a long period of time can be obtained. In addition, since we have provided an inclined surface on the hard seal packing side to guide the soft seal packing when opening and closing, even if there is slight change due to one gap, manufacturing process, or creep after long-term use, a complete seal will not be maintained. It is secured and the smoothness of non-opening and closing is maintained.

Also, it occurs on the sealing packing and the flange surface of the outer plate 7.
Since a corner seal is provided at the curved gap, the gap between the doors can be sealed more reliably, and the seal packing can be easily formed. In addition, the hard seal packing is filled with heat insulating material, and the heat insulating material adheres to the TI19 with its own adhesive strength, which not only simplifies manufacturing, but also improves the heat insulating performance of the seal packing. There are things that can prevent frosting. In addition, since the hard seal packing is installed on the upper edge of the lower door, even if the seal packing part is pressed while the door is open, it will not deform, resulting in an excellent appearance.
