a is provided.

The operation of the refrigerator provided with the door device configured as described above will be described below.

As shown in FIG. 5, double doors 107 and 108 are used.
When both are closed, the spring members 137a, 137a
Due to the restoring force of the 37b, the surfaces of the second gasket 134 are brought into close contact with each other to seal the refrigerator compartment 105a,
Further, the first fin portion 133a of the second gasket comes into contact with the overhang portions 114d, 115d of the concave portions of the door side plate from the inside, and the second fin portion 133b becomes the flat portion 114.
By contacting the surfaces of the b and 115b, the air inside and outside the refrigerator does not communicate with the inside of the refrigerator through the recesses 114a and 115a of the door side plate. Can be prevented.

Further, the second gaskets 134 are attracted to each other by joining the magnets 134a of different polarities built in the second gasket 134, so that the refrigerator compartment 1
05a can be improved in sealing performance. Magnet 1
Since a plurality of air layers 134b are continuously provided in the second gasket 134 from the refrigerator compartment 105a side in the second gasket 134, the magnet 134a is not directly cooled by the cool air in the refrigerator compartment 105a, so that problems such as dew condensation can be avoided. .

When the door is closed as shown in FIG. 5, the air layer 134b on the storage room side tends to be detached by the joining of the magnet 134a on the outside of the refrigerator. The 1 mm protruding piece 134d seals a gap generated between the second gaskets 134 to prevent cold air in the refrigerator compartment 105a from entering the gaps, and prevents condensation from forming around the second gasket 134. Can be prevented.

Next, as shown in FIG. 7, when the door 107 is opened, the holding member 129 is rotated by the rotation of the inclined surface 123 of the latch portion 125 along the protrusion 110 of the guide portion. It rotates around 127 as a fulcrum. As a result, the second gasket 134 is forcibly released from the close contact with each other, so that the second gasket 13
The surfaces of No. 4 do not rub against each other, and the durability of the gasket is improved. In addition, the surface of the gasket is not rubbed and static electricity is generated, so that no dirt is attached. In addition, generation of frictional noise due to rubbing is also eliminated. Moreover,
The door opening force can be reduced, and the usability of the user can be improved.

As shown in FIG. 8, the magnet 134a provided on the second gasket 134 is located on the line connecting the hinges 106 of both doors when the door is closed, so that the magnet 134a is effectively provided when the movable gasket 134 is closed. Magnet 1
The abutting portion 34a can be pressed into contact to enhance the sealing performance.

When the door 107 is further opened, the inclined surface 121 moves along the projection 110 of the guide portion 109 by the restoring force of the spring member 137a.
With the fulcrum 27, the holding member 129 returns to the same state as the door closed state. Thereby, the door side plate 111 and the holding member 12
No foreign matter can enter between them. The same can be said for the door closed state.

Next, when the door 107 is closed, the slope 1
The same effect as in the state where the door is opened can be obtained by the operation of the guide 21 and the inclined surface 123 along the protrusion 110 of the guide portion.

Further, as shown in FIG. 6, when the door is closed and opened, the rotating shafts 127 and 128 are fixed by the detachment preventing members 131 and 132. Thus, the holding members 129 and 130 do not come off the door side plates 114 and 115 due to the restoring force of the spring members 137a and 137b, and stable and smooth rotation can be obtained.

The rotating shafts 127 and 128 are connected to the door side plate 11.
Storage room 45a in doors 107 and 108 surrounded by
Since the second gasket 134 is disposed on the side, the second gasket 134 can be operated according to the door opening / closing operation without forcing the gasket abutting surface to slide firmly, so that the reliability of the gasket can be secured and extra force can be secured. Door opening and closing can be realized without adding.

At this time, the contact surfaces of the gaskets are made thicker than the non-contact surfaces to prevent breakage of the contact surfaces due to sliding, thereby ensuring the sealing performance.

Note that the rotating mechanism of the movable second gasket, such as the rotating shafts 127 and 128, the holding members 129 and 130, and the detachment preventing members 131 and 132, is provided with a concave portion 114 of the door side plate.
a, 115a because they are housed in
It does not violate the effective space inside the refrigerator or protrude outside the refrigerator, and does not interfere.

FIG. 9 is an exploded view of the door 108. In the assembly process of the door 108, the upper cover 112a, the lower cap 112b, the door side plate 115
Is fixed at a predetermined position, and a foam insulating material 118 is provided in the outer plate 112.
And the door inner plate 117 is fitted from above and fixed with a jig. At this time, the guide rib 1 provided on the door side plate 115
The projection 117b is engaged with a predetermined position by 15c.

The door inner plate 117 to be vacuum formed is different from the conventional door inner plate, and the door side plate 115 is engaged with the door inner plate 117. At this time, it is necessary to trim the door inner plate 117 into a shape suitable for the side shape of the door side plate 115. In order to join the door inner plate 117 to the door side plate 115 as described above, the first peripheral portion 117c and the second peripheral portion 117d are used.
A continuous portion occurs through the step. So the door inner plate 1
At the time of forming 17, the outer frame of the door inner plate 117 formed by vacuum forming is sequentially trimmed.
Degrees, ie, the first peripheral portion 117c and the second peripheral portion 117
When d communicates at right angles, door inner plate 1 after trimming
The trimming portion 17 has burrs and is very complicated. In order to ensure the quality state after molding, if the step is trimmed at an angle of 45 degrees or less, burrs do not occur as described above, and the joining can be performed with high accuracy.

Thereafter, a decorative member 138 is fixed to the molded door 108 by a locking member 139, and the doors 107, 1
The gap between the protruding portions 56b and 57b when 08 is closed can be narrowed. Thus, the cooling of the second gasket 134 by the cool air circulating therebetween can be reduced, and the dew condensation of the second gasket 134 can be prevented and the amount of heat absorbed can be reduced. At the same time, the decorative member 138
The cover covers the door side plates 114 and 115 from the surface, so that it can cover the appearance having irregularities and improve the design appearance.

Further, since the side end surface of the air layer 144 is formed flush with the side end surface of the magnet 141 as shown in FIG. 12, care is taken not to form a gap with the second gasket 134. Therefore, as shown in FIG.
Gasket 134 and first gasket extension 135
“d” is formed by pressing the second fin portion 133b with the side end surface of the magnet 141 and the air layer 144. As a result, no cool air leaks from between the second gasket 134 and the extension 135d of the first gasket.
The inside of 5a can be sealed.

Further, when the door is closed, pressure contact is performed, and when the door is opened, non-contact is frequently repeated. A flexible portion such as the second fin portion 133b corresponds to the place where the door is repeatedly opened and closed. Even if the gasket does not break or break, the durability of the gasket can be improved.

The base 147 and the second engagement piece 148 are formed of a hard member such as hard PVC, and
The first engagement piece 146 and the second engagement piece 14
8 are formed, so that the extending portion 135 is formed.
Even when the dimension is short as in d, the anchor portion 145 inserted at a predetermined position of the door does not come off. Further, since the first engagement side 146 is formed of a soft member, workability at the time of attachment and insertion is good.

The upper gasket portion 135a, the vertical gasket portion 135b, the lower gasket portion 135c, and the extension portion 13
5d connects the end faces to each other, and has a magnet 141 inside.
Is inserted and welded. As shown in FIG.
The end face of d is a soft member (in the case of this embodiment, soft PVC)
As a result, the magnet 141 inserted therein can be held and the air layer can be sealed.

Further, as shown in FIGS. 1 and 6, since the heater wire 140 is disposed on the door 107, it is possible to prevent the condensation formed on the second gasket 134 and the condensation formed near the flange 113. The operation panel 108 a is provided on the door 108 for the heater wire 140 of the door 107. With this, heater wire 1 by AC power supply
It is possible to separate a lead wire (not shown) from the DC power supply disposed on the operation panel 108a from the AC power supply 40, and it is possible to eliminate an erroneous operation failure of the operation panel 108a due to noise from DC to AC caused during this period.

As described above, since the structure is simpler than that of the conventional seal structure, it is possible to reduce the cost. Further, since a reliable close-sealing structure can be realized, the amount of heat passing through the gasket can be reduced, and the power consumption can be reduced by reducing the amount of heat entering, and the quality can be improved by preventing dew condensation around the gasket. together,
Durability reliability due to friction and sliding of the gasket can be improved.

With the above configuration and operation, the partition conventionally provided between the doors can be eliminated. Thereby, the frontage of the refrigerator compartment 105a can be widely used, and the food storage space in the refrigerator compartment 105a and the door storage portion 11 on the back surface of the door can be used.
The storage space of 6a and 117a is increased, and the usability and storage of the user can be improved. Further, since there is no partition, the gap between the doors is only the thickness of the pair of second gaskets 134, so that the amount of heat absorption can be reduced.

Further, the magnet 13 of the second gasket
4a and the rotation shaft 1 with respect to the distance between the rotation shafts 127 and 128.
Since the distance between the projections 110 provided in the refrigerator compartment 105a and the projections 27, 128 is increased, the doors 107, 108 can be opened with a light force by leverage with the pivots 127, 128 as fulcrums. If this distance ratio is set to about twice as described above, in a refrigerator room requiring a large amount of power to open and close due to a large storage load and a heavy weight as in the present embodiment, the lightness of door opening and closing and the sense of stability of opening and closing are moderate. And a door device with good operability can be provided.

Further, it is not necessary to displace the entire door at the time of opening and closing in order to ensure the close contact state of the second gasket 134, which complicates the hinge mechanism, lowers durability reliability and reduces cost. Also does not cost expensive. Further, the weight of the operational feeling and the uneasiness of the operation due to the displacement of the entire door at the time of the user's operation are eliminated.

Further, the refrigerator compartment 105 which is the uppermost storage compartment
By providing the door device in a, the sense of spaciousness of the frequently used storage room that the user can see and face can be improved, and the usability can be further enhanced.

Further, since the guide portion 109 for the latch portions 125 and 126 is provided on the upper surface in the refrigerator compartment 105a,
It does not hinder the loading and unloading of goods into and out of the refrigerator compartment 105a,
It does not affect storage.

When the above configuration and operation are provided only on one side of the door, the number of components required for rotating the second gasket 134 can be reduced by half, thereby improving the assemblability.
Material costs can be reduced.

In this embodiment, the second gasket 134 is provided between the two double doors 107 and 108. However, the same effect can be obtained by providing the second gasket 134 between the two drawer doors. Can be eliminated, and the effective size in the vertical direction of the storage container that enters and exits with the drawer door can be enlarged to increase the food storage space.

In FIG. 18, the door 308 has been described, but the above structure is also formed on the door 307 side.

[0141] Regarding the refrigerator configured as described above,
The operation will be described below.

When both the doors 307 and 308 are in the closed state, the second gaskets 319 are in close contact with each other, and the inside of the refrigerator compartment 305a can be sealed. Also the first
Fin portions 322, 323 and second fin portions 328, 329
