Generally, the airtight structure at the bottom of the door of this type of large refrigerator is designed to maintain airtightness between the door and the floor surface that the bottom of the door comes into contact with, since items are taken in and out of the refrigerator using a forklift or the like. If protrusions are formed, this may impede the passage of forklifts, etc., so this area is made airtight without forming protrusions, as shown in Figure 8. A heat insulating board 1 made of a heat insulating material such as urethane is surrounded by a door frame 2 made of a plastic shape, and the outer and inner surfaces are made of an aluminum plate or the like. A door 5 covered with an outer side member 3 and an inner side member 4, respectively.
A flexible door packing 6 made of synthetic rubber or the like is integrally formed at the bottom of a hollow door packing 6 with an approximately rectangular cross section that is fitted into the door frame 2 along the top, bottom, right and left edges of the inside surface of the door 5. A pair of band-shaped misaligned packings 7 made of a flexible material are suspended in parallel at intervals. Then, along the outer edge of the lower part of the door 5 and the left and right end edges, there is a band-shaped sag packing 8 made of a flexible material such as synthetic rubber, and the upper end thereof is formed of a band plate material. The sagging packing 8 is fixed to the door frame 2 with screws 10 via the sagging packing presser 9 to hang down, and both ends of the sagging packing 8 are
They are directly bonded to both ends of the misaligned packing 7 using an adhesive. The gap between the door 5 and the floor is closed by the shift packing 7 and the drip packing 8 described above, and airtightness is maintained.

端は同一長さにそろえるほうが望ましい。 Further, as shown in FIGS. 2 to 5, the door 11 is a door in which the periphery of a heat insulating plate 14 formed in a plate shape from a heat insulating material such as urethane is formed from a plastic material such as vinyl chloride. It is surrounded by a frame 15, and its outer and inner surfaces are respectively covered with an outer wall material 16 and an inner wall material 17 made of aluminum plates or the like. Then, along the upper, lower, left, and right edges of the inner surface of the door 11, second
3 and 4.
As shown in the figure, the mounting protrusion 18 is hollow and has an approximately rectangular cross section, and the protrusion 18 is L-shaped in cross section.
By being fitted into the door frame 15, a door packing 20 made of a flexible material such as synthetic rubber is attached. As shown in FIGS. 5 and 6, the lower edge packing 20' is integrally formed with the door packing 20' along the lower inner edge of the door 11 (see FIG. 4). A pair of staggered packings 21, which are made of a flexible material such as synthetic rubber and are formed into a strip shape, are suspended in parallel with a space between them. In addition,
The number of slippage packing 21 may be one,
It is also possible to use three or more sheets. and,
Along the outer edge of the lower part of the door 11 and the left and right edges of the lower part, a sag packing 22 is formed in the shape of a strip of a flexible material such as synthetic rubber, and the upper end thereof is formed of a strip material. It is hung down by being fixed to the door frame 15 with screws 24 via a sag packing presser foot 23. Note that it is preferable that the lower ends of the misalignment packing 22 are made to have the same length.

Since the airtight structure according to this invention is as described above, both ends of the slip packing 21 and the sag packing 22 at the bottom of the door 11 are connected via the columnar body 25 and reinforced, and when the door 11 is opened and closed, Also, since the columnar body 25 has appropriate elasticity and holds the connection part, the connection part has the effect of being difficult to come off or deform even if it is subjected to tension or twisting due to frictional force with the floor. . Therefore, door 11
This has the effect of improving the airtightness and heat insulation between the lower part and the floor, reducing damage to the slip packing 21 and the sagging packing 22 themselves, and improving durability. Also, when manufacturing the door 11, the columnar bodies 25 are used to pack both packings 2.
The bonding force for bonding 1 and 22 is easy because the bonding area is large, and workability is good, and the work can be done easily and quickly.
