It is related with the refrigerator by which packing 13 * 13 which partitions off the inside of a store | warehouse | chamber and the outside of a store | warehouse | chamber is distribute | arranged to the front end surface side of this.

  Each packing 13 includes an elastically deformable hollow packing body 15 which is abutted and joined to each other when both doors 3 and 3 are closed, and a base portion 16 for attaching the packing body 15 to the front end surface side of each door 3. The packing body 15 includes front and rear side walls 17 and 18 positioned inside and outside, and a projecting front end portion 19 that connects the front ends of the front and rear side walls 17 and 18, and is formed in a U-shaped cross section. (Patent Document 1).

Japanese Patent Laid-Open No. 11-294938 (paragraph numbers 0011 and 0020, FIG. 1)

  The hollow packing 13 having a U-shaped cross section is excellent in heat insulation because the packing main body 15 has a double heat insulating wall structure having side walls 17 and 18 on the front and rear. Further, when the doors 3 and 3 are closed, the projecting tip portions 19 and 19 of the opposing packings 13 and 13 are elastically deformed and strongly joined to each other, so that the airtightness is excellent.

  However, in a door with an automatic opening / closing mechanism or the like, there is a problem in that when the door closing force is small, the repulsive force between the packings wins and both doors are not closed.

  Therefore, the object of the present invention is to improve the packing that is elastically deformed and tightly joined in abutment when both doors are closed. An object of the present invention is to provide a refrigerator that can reliably seal the gap.

The present invention includes a refrigerator main body 1 with a pair of left and right double doors 3 and 3, and when the doors 3 and 3 are closed, a gap G is placed between the inside and In the refrigerator in which the packings 13 and 13 for partitioning the outside of the refrigerator are arranged in the vertical direction, each packing 13 is an elastically deformable hollow packing body 15 that is abutted and joined to each other when both doors 3 and 3 are closed; And a base portion 16 for attaching the packing main body 15 to the front end side of each door 3, and the packing main body 15 connects the front and rear side walls 17 and 18 positioned inside and outside and the front ends of the front and rear side walls 17 and 18 to each other. The front side wall 17 of the packing main body 15 includes a front end portion 19, and in order to bend and deform more easily than the rear side wall 18 , a rectangular bent portion 20 that is recessed toward the hollow interior of the packing main body 15 is vertically In the direction Stood is formed, a thin gasket main body 15 which tip 19 is formed on the projecting curved shape, and the base portion 16 of the thick leading to the proximal end of the longitudinal side walls 17, 18, integrally formed of an elastic plastic material The bent-shaped bent portion 20 is provided on the base end side with respect to the center portion of the front side wall 17 and the doors 3 and 3 are opened to release the pressing state of the packings 13 and 13. When the packings 13 and 13 are connected to each other, the front end portions 19 and 19 of the packings 13 and 13 project into a convex arc shape projecting outward in the left and right directions. The tip portions 19 and 19 of the 13 are configured so as to press each other and become linear .

  Here, the “character-shaped bent portion 20” includes a case where it is literally a character shape (V shape) in a cross-sectional plan view and a case where it is a U shape. The front side wall 17 may be bent in a square shape over the whole, or one or more bent portions 20 may be formed in the middle of the front side wall 17 in the left-right direction. The present invention also includes a form in which the front side wall 17 and the front end portion 19 are connected by a square-shaped bent portion 20. Although it is desirable that the rear side wall 18 of the packing body 15 is basically a straight wall between the left and right sides, the rear side wall 18 is also elastically deformed as long as the buckling strength is set higher than that of the front side wall 17. An allowable square-shaped bent portion may be formed.

  According to the packing 13 of the present invention, when the door 3 is closed, the front side wall 17 of the packing body 15 is bent in a buckled state when the front end portions 19 of the left and right packing bodies 15 collide with each other. Thus, the end portions 19 of the packing body 15 are easily abutted with each other due to their own elastic deformation. That is, since the impact resistance between the packings 13 and 13 is reduced, the door 3 can be closed with a light force.

  When both doors 3 and 3 are closed, the front side wall 17 of the bent packing body 15 exhibits an elastic restoring force, and the distal end portion 19 also has an elastic restoring force. Therefore, the tip portions 19 and 19 of the packing bodies 15 and 15 are maintained in a completely tightly joined state. The rear side wall 18 of the packing main body 15 functions to maintain the adhesion between the two end portions 19 and 19. Together, the gap G between the doors 3 and 3 is well sealed. Since the front side wall 17 of the packing body 15 is bent and deformed without difficulty, the packing body 15 is excellent in durability without being locally broken even if it is repeatedly used over a long period of time.

  If the packing body 15 and the base portion 16 are integrally molded with plastic, the entire packing 13 can be mass-produced at low cost by extrusion molding. At that time, if the packing body 15 is formed thinner than the base portion 16, the elasticity of the packing body 15 can be secured, and if the base portion 16 is formed thicker than the packing body 15, the door 3. The pace portion 16 can be securely attached to the side.

  In FIG. 2, the refrigerator main body 1 has storage chambers 2 and 2 that are divided into two upper and lower stages. The refrigerator main body 1 is provided with a pair of left and right doors 3 that open and close the front of the opening of each storage chamber 2.

  Each door 3 is pivotally supported on the refrigerator main body 1 by a hinge 4 at the base end side, and can swing open and close in a double-sided manner from the closed position to the left and right. Both doors 3 are maintained in a closed position by a magnet catch 5 provided on the refrigerator body 1 side.

  On the periphery of the inner wall surface 6 on the inner side of each door 3, a paragraph portion 7 is provided in a circular shape, and a door packing 9 is attached to the paragraph portion 7. When the door 3 is closed, the door packing 9 is brought into close contact with the peripheral wall surface of the front surface of the refrigerator main body 1 through the magnet 10 incorporated therein.

  The front of the opening of the refrigerator body 1 does not have a support column at the left and right center. Therefore, when both the doors 3 and 3 are closed, a gap G leading to the inside and outside is formed between the opposite end surfaces 3a and 3a.

  In order to seal the gap G between the front end surfaces 3a and 3a of the doors 3 and 3, a sealing means is provided. The sealing means includes a seal frame 11, a plate seal 12 and a packing 13 attached inside and outside (front and rear) of the seal frame 11.

  In FIG. 3, on the inner wall surface 6 of each door 3, a vertically long, hollow, hard plastic seal frame 11 is provided between the upper and lower sides on the inner outer surface of the door packing 9 so as to straddle the front end surface 3 a on the swing front end side of each door 3. Install over. A plate seal 12 made of an elastically deformable soft plastic formed in a vertically long flat plate shape is extended in a cantilever manner between the upper and lower sides on the opposing surface of the seal frame 11. When the doors 3 and 3 are closed, the plate seals 12 and 12 are in surface contact with each other inside and outside.

  In each seal frame 11, the packing 13 is arranged on the opposite wall surface protruding inward from the inner wall surface 6 of each door 3 in a left-right opposed manner. The backing 13 is located at a predetermined interval on the inner side of the plate seal 12.

  1, each packing 13 includes an elastically deformable hollow packing body 15 which is abutted and joined to each other when both doors 3 and 3 are closed, and the packing body 15 is connected to the front end surface 3a side of each door 3, that is, each seal. And a base portion 16 for attaching to the inner wall protruding wall surface of the frame 11. The packing main body 15 and the base portion 16 are integrally molded by an elastic plastic material.

  The packing body 15 includes front and rear side walls 17 and 18 positioned inside and outside, and a front end portion 19 that projects in a semicircular shape and connects the front and rear side walls 17 and 18 to each other, and is thinner than the thickness of the base portion 16. It is easy to make elastic deformation.

  The base portion 16 is formed thicker than the packing main body 15 so that the thickness of the base portion 16 is not easily elastically deformed, and the base ends of the front and rear side walls 17 and 18 of the packing main body 15 are connected to the base portion 16. Yes. Thereby, the packing body 15 is formed in a vertically long hollow whose base end side is closed by the base portion 16, and the upper and lower ends of the packing body 15 are closed by the cap.

  In order to make bending deformation easier than that of the rear side wall 18 in the middle part of the front side wall 17 of the packing body 15, as shown in FIG. It is integrally formed over the direction.

  As shown in FIG. 4, each packing 13 is attached by fitting the base portion 16 into an attachment port 21 provided in the seal frame 11.

  According to such a seal structure, when the doors 3 and 3 are closed simultaneously, the packings 13 and 13 first collide with the inner side (rear side) of the front end portions 19 and 19 of the packing body 15. At this time, each packing body 15 has its front side wall 17 bent in a buckled state due to the presence of the bent portion 20, so that the tip portions 19 and 19 of both packing bodies 15 and 15 are coupled with their own elastic deformation. Surface bonding is performed in a butt shape without resistance (state of FIG. 1). In other words, the door can be set in a completely sealed state with a light force.

  Even when one door 3 is closed and the other door 3 is closed from the open position, the outer side (front side) and the inner side (rear side) of the front end portions 19 and 19 of both packing bodies 15 and 15 When the front walls 17 and 17 of the packing main bodies 15 and 15 are bent, the tip portions 19 and 19 of the packing main bodies 15 and 15 are elastically deformed with each other and are brought into a butted state with a light force. Can be set.

  In the state of FIG. 1 in which both doors 3 and 3 are closed, the packing 13 adopts a double heat insulating wall structure with front and rear side walls 17 and 18, so that sufficient heat insulation is obtained and no condensation occurs. In addition, since the elastic restoring force acts on the distal end portion 19 of the bent portion 20 and the distal end portion 19 of the packing body 15, the distal end portions 19 and 19 of both packing bodies 15 and 15 are securely bonded to each other. Then, the gap G between the doors 3 and 3 is sealed.

(Another Example) The packing body 15 may be made of a soft plastic material, and the base portion 16 may be made of a hard plastic material and separately molded and then combined. If the bent portion 20 is formed so as to enter the hollow interior of the packing body 15 as in the previous embodiment, it is advantageous to prevent the bent portion 20 from coming into contact with other objects. If there is a margin, the bent portion 20 may be bent so as to protrude in a square shape toward the front outer side of the front side wall 17.

  The front end portion 19 of the packing body 15 may be bent in two ridges (M-shaped) or may be flat, and the shape itself is not particularly limited.
