Description

[Detailed Description of the Invention] The present invention relates to a constant temperature device such as a refrigerator, which is provided with a gasket for sealing on the inner edge of the opposite side of the double-door door that opens and closes the front opening of the case body.

Generally, in refrigerators that have left and right doors that can be opened on both sides, gaskets provided on the inner edges of the opposite sides of both doors come into contact with each other to keep the inside of the refrigerator airtight. It was equipped with a closing member such as art supplies.

Therefore, this closing member becomes a putty space inside the warehouse, and also has the disadvantage that it becomes an obstacle to the operation of taking out and taking out articles.

□Conventionally, therefore, a gasket with a single layer of protruding tongues was installed on the inner edge of both doors on the opposite side, and when both doors were closed, the protruding tongues of both doors were engaged to close the inside of the refrigerator. The partition material was being removed.

However, since the protruding tongues are a single layer, they have insufficient heat insulation, weaken after long-term use, and have the disadvantage that the protruding tongues do not engage with each other sufficiently.

The present invention eliminates the above-mentioned drawbacks of the prior art, and an embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is the insulation box body made of a urethane foam insulation layer.
A left door 2 and a right door 2' are rotatably pivoted to the front opening via hinges 3, 3' at left and right positions to form a double door.

Reference numeral 4 denotes a gasket for sealing the inside of the refrigerator, surrounding the outer periphery of the back surfaces of the left and right doors 2, 2' and fixed with screws or the like together with the end edges of the inner surfaces 5 and 5'. , of which
The three pieces on the door side and the upper and lower sides are in contact with the front opening periphery 1a of the insulation box body 1.

The gasket 4 is made of an elastic material such as a synthetic resin, and has a cross-sectional shape consisting of a bag-shaped part 6 containing a magnet 6a, a mounting part 7 fixed to the outer peripheral edge of the door, and the mounting part 7 and the bag-shaped part 6. and an air insulating chamber 8 which elastically connects the two.

Also, the gaskets 4a, 4 on the opposite side of the left and right doors 2, 2'
a' is made of an elastic material such as synthetic resin like the gasket 4, and has bag-shaped parts 9, 9' and a mounting part 10 of almost the same shape.
, 10' and air insulating chambers 11° and 11' which elastically connect the two, and are integrated with the three pieces of the gasket 4 to form a frame.

Further, the gasket pieces 4a, 4a' on the opposite side of the door are provided with protrusions toward the outer periphery of the doors 2, 2' on the outside of the front opening periphery 1a, and have bag-like parts 9, 9' and a mounting part 10. ,
a first protruding bag portion 12 integrally formed across 10';
12' is provided.

Reference numeral 13.13' denotes a second protruding bag part that protrudes upward toward the outer periphery of the door inside the front opening inner edge 1a, and this second protruding bag part 13. coupled to the gaskets 14, 14', and the first protruding bag portion 1
2.12' is in contact with the base.

Therefore, the first protruding bag portion 12 of the left door 2 and the right door 2',
12' and inner gaskets 14 and 14' protrude at substantially the same height, and when both doors 2.2' are closed, the first protruding bag portions 12 and 12' and the second inner gaskets N4 and 14' The outer tips of the protruding bag portions 13 and 13' are configured to engage with each other.

In the above-mentioned configuration, when both doors 2, 2' are closed, the doors 2, 2
The front opening of the insulation box body 1 is completely sealed by the engagement of the gaskets 4 on the door side and on both upper and lower sides with the opening peripheral edge 1a of the insulation box body 1.

The outer wall portions of the left and right doors 2, 2' on the joint side, that is, on the opposite side, are connected to the first protruding bag portion 12 of the gasket piece 4a on the left door 2 side, and the first protruding bag portion 12 of the gasket piece 4a on the left door 2 side. The contact between the gasket piece 4a' on the 2' side and the first protruding bag part 12', and the contact between the second protruding bag part 13 on the left door 2 side and the second protruding part 13' on the right door 2' side. Since the opening 15 between the doors 2 and 2' is covered by the opening 15, it is possible to completely block the flow of air into the refrigerator.

Note that the first and second protruding bag portions 12, 12', 1
3. If a flexible heat insulating material is inserted within 13' without damaging its flexibility, the heat insulating effect will be further enhanced.

As described above, the present invention includes an insulating box main body having an opening surface, a double-opening door that closes the opening surface of the insulating box main body, and a door that is fixed to the outer periphery of the back surface of the insulating box body and abuts against the periphery of the opening surface. and a gasket made of an elastic body, of which the gasket on the opposite side of the door is located outside the opening surface when both doors are closed, and has a first protruding bag-shaped part whose tips are joined to each other. , a second protruding bag part located on the inner side of the refrigerator than the opening surface is provided, and the space on the opposite side of both doors can be double-blocked between the inside and outside of the refrigerator by the first and second protruding bag parts, and it can be used for a long time. Since the first and second protruding bag parts are bags during use, there is little deterioration, and furthermore, both protruding bag parts can be used inside the refrigerator on the opening side.
Since it is located on both the outside of the refrigerator, it has practical value, such as improved airtightness and better insulation.
