Description

  The present invention relates to a seal member attached to a heat insulation door of a refrigerator.

  Devices that require insulation, such as a refrigerator, insulate by sealing between the insulation door and the refrigerator body. In the sealing method, in addition to the door packing, air is shut off by a seal member which is a separate member from the door packing. The sealing member is attached to the convex inner wall of the heat insulating door and is in contact with the inner wall of the opposite storage chamber. Thereby, the gap between the convex inner wall of the heat insulating door and the inner wall of the storage chamber can be filled to block the air. The seal member creates a layer of cushioning air between the air of the storage chamber and the outside air.

  However, since the sealing member is attached only to the adhesive to the convex inner wall of the heat insulating door, there is a problem that the sealing member is detached when cleaning is performed or when the content is caught by the operation of the drawer. In addition, since the door packing and the sealing member are separated without contact, the sealing member may not come in contact with the inner wall of the storage chamber.

  Therefore, in order to ensure that the seal member contacts both the inner wall of the storage chamber and the inner wall of the heat insulating door, Patent Document 1 discloses that the door packing and the soft seal member are integrally formed.

(C) The C section enlarged view of FIG.5 (b), (d) It is the C section enlarged view of FIG.5 (b) in the state which closed the heat insulation door 5c. With reference to FIG. 5, joining of the door packing 15 of the heat insulation door 5c which concerns on one Embodiment of this invention, and the sealing member 13 is demonstrated.

  About FIG. 5A and FIG. 5B, since it becomes repetition with FIG. 3, FIG. 4, description is abbreviate | omitted. As shown in FIG. 5C, the heat insulating door 5c includes a convex inner wall 17, a recessed groove 23, and a flat surface 19 of the outer periphery.

  The door packing 15 is provided so as to overlap the flat surface 19 of the outer periphery. Moreover, the door packing 15 is comprised with the material which elastically deforms. As shown in FIG. 5 (d), the door packing 15 seals the heat-insulated door 5c and the refrigerator main body 3 by contacting and deforming the surface 6d of the storage room 7c.

  As shown in the enlarged view C of FIG. 5 (c), the door packing 15 comprises a portion 25 attached to the groove and a magnet 27. The magnetic force of the magnet 27 of the door packing 15 serves as a force for intimate contact with the refrigerator body 3 and is integral with the door packing 15, so that the heat insulating door 5c and the refrigerator body 3 can be attracted. The door packing 15 is in close contact with the suction portion of the refrigerator main body 3 by the magnet 27 when the heat insulation door 5 c is closed.

  The door packing 15 joins the door packing 15 to the heat insulation door 5c by fitting the part 25 attached to the groove into the groove 23 provided in the heat insulation door 5c. The portion 25 attached to the groove has a stopper with a cross section of the arrow at the tip of the body that fits closely into the recessed groove 23.

  The portion 25 attached to the groove can prevent air from communicating between the heat insulating door 5 c and the door packing 15 by the body portion closely fitted to the recessed groove 23. When the heat insulating door 5c is opened by the stopper having the cross section of the arrow, the adhesion between the refrigerator body 3 and the door packing 15 overcomes the connection between the door packing 15 and the heat insulating door 5c and the door packing 15 is detached. There is no need to worry.

  As shown in the enlarged view C of FIG. 5C, the seal member 13 is provided in contact with the outside of the heat insulation door 5c of the convex inner wall 17 so as to edge into the groove 23 recessed in the heat insulation door 5c. It is done. In the recessed groove 23, the portion 25 attached to the groove of the door packing 15 is fitted from above the sealing member 13. Further, the seal member 13 is bonded to the heat insulating door 5c with an adhesive. The sealing member 13 is held together with the door packing 15 on the heat insulating door 5 c by the fitting and the adhesive.

  Both the door packing 15 and the sealing member 13 are held by the groove 23 recessed in the heat insulating door 5c, so that the sealing member 13 can be firmly fixed, and the sealing member 13 is It does not come off at the time of cleaning or the operation of the drawer.

  Further, since the door packing 15 and the sealing member 13 are both held in the groove 23 recessed in the heat insulating door 5c, the sealing property is excellent and the heat insulating effect is provided.

  Furthermore, according to the present invention, by making the door packing 15 and the sealing member 13 separate, the cost of parts can be reduced because the structure of the parts to be replaced is not complicated when either is broken.

  The sealing member 13 and the door packing 15 are formed of a material that is elastically deformed, such as rubber. As these materials, rubbers such as urethane rubber, silicone rubber, ethylene propylene rubber, chloroprene rubber, polyethylene resin, polyvinyl chloride and the like can be used. These materials may be selected in consideration of weather resistance, chemical resistance and the like.

  As shown in FIG. 5 (d), the seal member 13 has a whisker structure 21 at its tip. The whisker structure 21 softly deforms in contact with the inner wall 8d of the storage chamber. This whisker structure 21 creates a layer of air by extending parallel to the side direction of the heat insulating door 5c. The sealing member 13 can fill the gap between the convex inner wall 17 of the heat insulating door 7c and the inner wall 8d of the storage room 7c to block air.

  As the number of the whisker structures 21 increases, the heat insulating effect is obtained. However, it is preferable that the number of the whisker structures 21 be two or so so as not to complicate the structure.

  Although not shown, the tip of the seal member 13 may have a sack structure instead of the whisker structure 21 to create a layer of air in the sack structure and to improve the adhesion with the inner wall 8d of the storage chamber 7c. be able to.

  Although the heat insulating door and the storage room showed three refrigerators 1 in this embodiment, the number of the heat insulating door and the storage room may be one or more. Moreover, the heat insulation door and storage room provided with a shelf may be the upper part or the lower part of the refrigerator main body 3 provided with the divided storage room.

  Although this embodiment showed the example which attaches the sealing member 13 to the lower side of the heat insulation door 5c, it is not restricted to this. The sealing member 13 may be attached only to the lower side and both side surfaces of the heat insulating door 5c or both side surfaces. Even in such a case, the door packing 15 and the sealing member 13 are both attached to the recessed groove of the heat insulating door 5c.

  Thus, the present invention strengthens the adhesion of the seal member and is excellent in air tightness, but is a refrigerator composed of uncomplicated parts, that is, the seal member does not come off in cleaning and drawing operations, and is excellent in heat insulation. Can provide a refrigerator with reduced cost of replacement parts.
