Definitions

  • the present invention relates to a refrigerator, and more particularly, to a sealing gasket for a refrigerator capable of preventing cool air from leaking from the refrigerator and/or preventing warm air from entering the refrigerator.
  • a refrigerator generates cool air via a refrigerating cycle performed by a compressor, a condenser, an expansion valve, an evaporator, etc.
  • the cool aft is introduced into the refrigerator so that food can be stored therein in a cool state or a frozen state.
  • leakage of the cool air from the refrigerator or introduction of external warm air into the refrigerator has to be effectively prevented.
  • a gasket is typically installed at contact surfaces between a refrigerator body and a refrigerator door.
  • An outer surface of the gasket is typically formed of a synthetic material having an elastic characteristic, and a magnet is installed in the gasket.
  • the prior aft sealing apparatus for a refrigerator has the following problems.
  • the magnet inside of the gasket, or the front surface plate of the refrigerator body are not flat, or when a magnetic force of the magnet becomes weak, cool air can leak from the refrigerator body or external warm air may be introduced into the refrigerator body. As a result, power consumption is increased.
  • FIGs. 1 and 2 show a refrigerator body 10 having a cooling chamber 12 and a freezing chamber 13 installed at right and left sides of a partition wall 11.
  • Two refrigerator doors 20 are rotatably installed at sides of the refrigerator body 10, for independently opening and closing the cooling chamber 12 and the freezing chamber 13 of the refrigerator body.
  • a plurality of gaskets 30 are fixedly coupled to the refrigerator doors 20. Edges of the doors 20 are designed to contact the partition wall 11 of the refrigerator body 10 to seal off the cooling chamber 12 and the freezing chamber 13.
  • a magnet 36 is mounted inside the gasket 30, and the magnet 36 is attracted to the front surface plate 14.
  • the magnetic attraction between the magnet 36 and the front surface plate 14 helps to keep the door shut, and helps to ensure that a good seal is made around the peripheral surface of the door.
  • a thermal line 15 for preventing the formation of condensed moisture is installed at a rear surface of the front surface plate.
  • an outer surface of the front surface plate 14 is even and flat so that the magnet 36 of the gasket 30 can ensure a good seal between the gasket 30 and the front surface plate.
  • a gasket fixing groove 22 for insertion-fixing a coupling portion 31 of the gasket 30 is formed at an inner case 21 of the refrigerator door 20.
  • the gasket 30 comprises a coupling portion 31 which is inserted into the inner case 21 of the refrigerator door 20.
  • a connecting portion 32 integrally extends from the coupling portion 31 so as to be foldable.
  • An adhering portion 33 integrally extends from the connecting portion 32 and is detachably mounted at the front surface plate 14 of the refrigerator body 10 due to the magnetic attraction between the magnet 36 and the front surface plate 14.
  • a first shielding portion 34a and a second shielding portion 34b respectively protrude from opposite sides of the adhering portion 33. The ends of the first and second shielding portions extend upwards from the adhering portion 33. The first and second shielding portions also help to ensure a good seal.
  • the coupling portion 31 has an anchor shape so as to be insertion-coupled to the gasket fixing groove 22 of the refrigerator door 20.
  • the connecting portion 32 is divided into a plurality of partitions by walls 35 so as to form an inner space.
  • the shielding portions contact the refrigerator body 10 before than the adhering portion 33.
  • the first and second shielding portions are tapered.
  • the first shielding portion 34a is formed at an inner edge of the adhering portion 33 and contacts the inner case 16 of the refrigerator body 10, thereby preventing cool air inside the cooling chamber 12 or the freezing chamber 13 from leaking out.
  • the second shielding portion 34b is formed at an outer edge of the adhering portion 33 and contacts the front surface plate 14, thereby preventing external warm air from being introduced into the refrigerator.
  • the first and second sealing portions are substantially straight. As the door is closed, the first and second sealing portions are elastically deformed until they assume the shape shown in FIG. 2. This elastic deformation of the sealing portions helps hold the sealing portions firmly against the refrigerator body to ensure a good seal.
  • the first shielding portion 34a and second shielding portion 34b may have curved surfaces that also extend upward from the adhering portion 33.
  • the shielding portions are elastically deformed to hold the sealing portions firmly against the refrigerator body.
  • the adhering portion 33 of the gasket 30 coupled to the refrigerator door 20 is adhered to the front surface plate 14 of the refrigerator body 10 due to the magnetic attraction between the magnet 36 in the gasket and the front sealing plate on the refrigerator body. Accordingly, cool air inside the refrigerator is prevented from leaking out, and/or external warm air is prevented from being introduced into the refrigerator.
  • the first shielding portion 34a and the second shielding are protrudingly-formed at opposite sides of the adhering portion 33 of the gasket 30.
  • the first shielding portion 34a and the second shielding portion 34b contact the inner case 16 and the front surface plate 14 of the refrigerator body 10, respectively, before the adhering portion 33.
  • the first shielding portion 34a and the second shielding portion 34b are elastically deformed, thereby enhancing a sealing force for the gasket 30.
  • the first shielding portion 34a and the second shielding portion 34b are tapered and are formed to have a curved surface or an inclined surface in a closing direction of the refrigerator door 20. These features ensure that when the refrigerator door 20 is closed, the first shielding portion 34a and the second shielding are elastically deformed, thus intensively adhering to the sealing surfaces of the refrigerator body.
  • the gasket was installed on the refrigerator door.
  • the gasket can be installed on the refrigerator body.
  • the construction and effect are same as those of the aforementioned embodiment.
  • the sealing gaskets disclosed in the application are equally applicable to other types of refrigerator/freezers.
  • the gaskets disclosed in this application could be used on just a refrigerator, or just a freezer.
  • shielding portions extended from opposite sides of the adhering portion of the gasket.
  • only a single shielding portion may extend from only a single side of the adhering portion.
  • a plurality of shielding portions may extend from one or both sides of the adhering portion.
  • any reference in this specification to "one embodiment”, “an embodiment”, “example embodiment” etc. means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention.
  • the appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment.
