Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention has upper and lower container doors that slide on rails provided inside 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 edge of the lower door.

[Background of the invention]

Conventional refrigerators of this type usually have a dough-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 attached to the door must be sized to avoid this partition frame, which reduces the height of the container itself, and the partition frame becomes an obstacle when taking out items stored in the container. There were some flaws.

Examples of refrigerators related to this type include Utility Model No. 54-1
No. 68665, etc. may be mentioned.

[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 upper and lower container doors that slide on rails provided inside the refrigerator and can be freely pulled out, and seals are attached to the lower edge of the adjacent upper door and the upper edge of the lower door. In a refrigerator equipped with a sealing packing, when the door with the container is in the stored state, the sealing packing comes into contact with the previous sealing packing, and the opening/closing operation is made smooth when the door is drawn out or closed.

[Embodiments of the invention]

The details of the present invention will be explained below using an example shown in the drawings.
1 is a refrigerator main body, and this main body 1 has an outer panel 2 on the outside, a refrigerator compartment interior 3, and a freezer compartment interior 16 inside. 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 the first, second, third, fourth, and fifth names that close the front opening of the refrigerator compartment main body. Each industry uses food storage containers 5a and 6a, either integrally or separately.
, 7a, ga, and 9a. Each container has a plurality of rollers 4 that slide on the inside rail 3a.

14 is a lower edge packing of the door 5, and 15 is an upper edge packing of the door 6, both of which are configured to closely contact the front surface of the partition 13 described above.

The lower edge of the door 6.7.8 and the upper edge of the garlic 7.8.9 are sealed between the adjacent spaces of 1, so between the doors 6 and 7, between the doors 7 and 8, The inner side of the refrigerator between s8 and s9 is not provided with a partition like the above-mentioned inner partition 13 or a stock-shaped partition frame that has been conventionally used. To explain the airtight structure between the doors as a representative example using enlarged views (Figs. 2 to 4) between doors 8 and 9, a soft seal packing 10 is attached to the lower edge of the door n8. 8b and seal packing 10
A mounting claw 10b is attached thereto. A hard seal packing 12 is attached to the upper edge of n9 located below n8.
By contacting with the seal packing 10 described above, the space between the sums of 8.9 and 8.9 is 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, thereby improving the sealing performance of the seal packings 10 and 12. Seal packing 10
The IOC, which is the contact surface of 12, is coated with a lubricant, such as a fluorine-containing lubricant, to reduce friction during contact.

The seal packing 12 that comes into contact with the soft seal packing 10 is made of a lubricating hard plastic filled with fluorine-based or fluorine-based resin in order to reduce the opening and closing resistance of the door due to friction when they are in close contact with each other. There is. In addition, the gap G8 between the doors 8 and 9 may vary slightly due to the manufacturing technology of parts and assembly, so the seal packing 10 itself is designed to accommodate changes in the gap G8. It is made of flexible soft plastic. 12e is designed to prevent the seal packing 10 from colliding, considering the case where s8, which was in the open 1 state when the rod 9 is closed, closes, and also considering the sagging of the seal packing 10 and the change in the gap G8 described above. The guide part is inclined toward the outside of the refrigerator. , 12b similarly determines the seal packing by considering the case where the door 8 is in the closed state when the door 9 is closed from the open state, and also by taking into account the sagging of the seal packing 10 and the change in the gap G8. The guide part is inclined toward the inside of the refrigerator so as not to collide with the guide part 10. 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 when foamed, which is provided on the inside flange 9e side of the door. Since the urethane is cured after being filled into the space 12f, the seal packing 12 is more firmly fixed to the door 9 due to the adhesive force of the urethane itself. Reference numeral 11 indicates a corner seal, and one inclined guide portion 12 of the seal packing 12 described above.
b, the approximately 〉-shaped gap formed between the front surface 7 flange 2a of the outer plate and the seal packings 10 and 12 is sealed.

〔Effect of the invention〕

The present invention is as explained above (the sealing packing on the lower edge of the upper door is made soft, and the sealing packing on the upper edge of the lower door that contacts the sealing packing is made hard), so that the resistance due to friction when they abut each other is reduced. This makes it easier to open and close the pull-out enclosure, and the soft and hard seals improve the airtightness between the doors, making it possible to eliminate the conventional partition frame. In addition, a bottom friction agent is applied to the soft seal packing, and the hard seal packing is made of a low-friction material, so even if the contact force for sealing the drawer-type door is increased, the opening/closing operation of the door will not be difficult. It is easy to make, and the twisting force applied to the soft seal packing when opening and closing the door is small, so a seal structure that can be used safely for a long time can be obtained.In addition, on the hard seal packing side, there is a soft seal when opening and closing the door. Since we have provided an inclined surface to act as a packing guide, even if the door gap changes slightly due to manufacturing or creep after long-term use,
This ensures a perfect seal and the smooth opening and closing of the door.

In addition, ≧ occurs on the sealing packing and outer plate flange surface.
Since the corner seals are provided in the gaps, the gaps between the doors can be more securely sealed, and the seal packing can be easily formed. In addition, since the hard seal packing is filled with heat insulating material and is fixed to the door 9 by its own adhesive strength, it is not only easier to manufacture, but also improves the heat insulating performance of the seal packing and prevents the outside of the refrigerator. It prevents frost build-up. Furthermore, since the hard seal packing is installed on the upper edge of the lower door, it will not deform even if the seal packing part is pressed while the door is open (this also results in an excellent appearance).
