BACKGROUND ART

Generally, a refrigerator is an appliance that includes storage chambers and a cold air supply unit which supplies cold air to the storage chambers and keeps food fresh.

The temperature of the storage chamber is maintained in a predetermined range desired for keeping the food fresh.

Such a storage chamber of the refrigerator is provided with a front surface to be opened, and the open front surface is closed by a door at ordinary times to maintain the temperature of the storage chamber.

A plurality of storage chambers are partitioned by partitions, the storage chambers provided at an upper side among the plurality of storage chambers are opened and closed by double-door-type doors which are rotatably hinge-coupled, and the storage chambers provided at a lower side are opened and closed by drawer type doors which slides in a forward and backward direction.

A dispenser unit capable of discharging water and ice at an outside of a main body is provided at the double-door-type door, and the dispenser unit is coupled to a rear surface of the double-door-type door of the front plate.

After the dispenser unit is coupled to the rear surface of the front plate, an additional operation such as a taping operation or a sealing operation around an edge of the dispenser unit is required to prevent a thermal insulating material filling the inside of the double-door-type door from leaking between the front plate and the dispenser unit.

When the taping operation is performed between the front plate and the dispenser unit with subsidiary materials such as tapes to prevent the leakage of the thermal insulating material, the front plate may be bent while the thermal insulating material filling the inside of the double-door-type door is absorbed into the subsidiary material and hardened.

The subsidiary material has to be separated from the thermal insulating material such that the front plate is not bent, and to this end, the subsidiary material has to be covered with felt and the like into which the thermal insulating material is not absorbed so as not to be in contact with the thermal insulating material.

A machine compartment (not shown), in which the compressor which compresses a refrigerant and the condenser which condenses the compressed refrigerant are installed, may be provided at a lower portion in a rear side of the main body 10.

The plurality of storage chambers 20 may be partitioned into an upper chamber 21, an intermediate chamber 23, and a lower chamber 25 by partitions 11, and each of the chambers may refrigerate or freeze and store food as necessary.

A plurality of shelves 27 may be provided in the upper chamber 21 and divide the upper chamber 21 into a plurality of spaces, and a plurality of storage containers 29 capable of storing food and the like may be provided in the upper chamber 21.

The upper chamber 21 may be opened and closed by the doors 30 pivotably coupled to the main body 10, and the intermediate chamber 23 and the lower chamber 25 may be respectively opened and closed by the storage units 40 capable of sliding with respect to the main body 10.

Handles 31 may be provided on a front surface of the doors 30, and a plurality of door guards 33 capable of storing food and the like may be installed on a rear surface of the doors 30.

The storage units 40 may include drawer type doors 41 which open and close the intermediate chamber 23 and the lower chamber 25, and storage containers 43 installed on rear surfaces of the drawer type doors 41, and drawer handles 41a that a user can grip may be provided on the drawer type doors 41.

The storage containers 43 may be provided to be integrally formed with the drawer type doors 41, or may be provided by a method in which the storage containers 43 are manufactured separately from the drawer type doors 41 and are coupled to the drawer type doors 41.

The storage units 40 may slide in or out from the intermediate chamber 23 and the lower chamber 25 by sliding units 50.

The dispenser unit 70 is coupled to the door 30 so that a discharge groove 71 is exposed to the outside of the door 30, and water and ice in the main body 10 may be discharged to the outside of the main body 10 through the discharge groove 71 even without opening the door 30.

Next, a process of coupling the dispenser unit 70 to the door 30 will be described with reference to FIGS. 2 to 13.

As illustrated in FIGS. 2 to 4, the door 30 includes a front plate 60 disposed at a front surface of the door 30 to form an exterior, and an opening 61 configured to expose the discharge groove 71 of the dispenser unit 70 to the outside is provided in the front plate 60.

The dispenser unit 70 is coupled to a rear surface of the front plate 60 so that the discharge groove 71 faces the front plate 60, and the discharge groove 71 is exposed to the outside of the door 30 through the opening 61.

A user may discharge water and ice included in the main body 10 through the discharge groove 71 exposed to the outside of the door 30.

A gasket 80 is coupled to the dispenser unit 70 coupled to the rear surface of the front plate 60 to prevent the thermal insulating material U filling the door 30 from leaking between the front plate 60 and the dispenser unit 70.

An insertion groove 75 into which the gasket 80 is inserted is provided at an edge portion 73 of the dispenser unit 70 to seal between the front plate 60 and the dispenser unit 70 so as to prevent the leakage of the thermal insulating material U by the gasket 80 inserted into the insertion groove 75.

As illustrated in FIGS. 5 to 6, it is preferable that the gasket 80 be inserted into the insertion groove 75 of the dispenser unit 70 to protrude forward from a front surface of the dispenser unit 70.

Thus, as illustrated in FIGS. 10 and 11, when the dispenser unit 70 is coupled to the front plate 60, the gasket 80 is pressed against the rear surface of the front plate 60 to more firmly seal between the front plate 60 and the dispenser unit 70.

Since the gasket 80 seals between the front plate 60 and the dispenser unit 70, after the dispenser unit 70 is coupled to the front plate 60, an additional taping or sealing operation for preventing the leakage of the thermal insulating material U is not needed.

In addition, when the taping or sealing operation is performed at the edge portion 73 of the dispenser unit 70 and the thermal insulating material U filling the door 30 is in contact with a tape or the like, since the tape or the like absorbs the thermal insulating material U, and thus the front plate 60 becomes bent, after the taping or sealing operation is performed at the edge portion 73 of the dispenser unit 70, a portion in which the taping or sealing operation is performed is covered by felt which does not absorb the thermal insulating material U in order to separate the tape or the like from the thermal insulating material U. However, when the gasket 80 seals between the front plate 60 and the dispenser unit 70, additional subsidiary materials may not be needed.

Accordingly, as illustrated in FIG. 10, the thermal insulating material U filling the door 30 is in direct contact with the rear surface of the front plate 60. As illustrated in FIGS. 4 and 7, a plurality of hooks 63 are provided at the opening 61 of the front plate 60 to couple the dispenser unit 70 to the rear surface of the front plate 60, and a plurality of fixing holes 77 are provided in the dispenser unit 70 at positions corresponding to the plurality of hooks 63.

By the plurality of hooks 63 provided at the front plate 60 being inserted into the plurality of fixing holes 77 provided in the dispenser unit 70, the dispenser unit 70 is pressed against the rear surface of the front plate 60. Next, as illustrated in FIG. 8, by bending the hooks 63, the dispenser unit 70 is fixed to the front plate 60.

After the dispenser unit 70 is fixed to the front plate 60, the fixing hole 77 is covered by a cap 90 to be sealed as illustrated in FIGS. 8 and 9 to prevent the thermal insulating material U from leaking through the fixing hole 77.

When the dispenser unit 70 is fixed to the rear surface of the front plate 60, since the dispenser unit 70 is pressed against the rear surface of the front plate 60, the surroundings of the opening 61 of the front plate 60 in contact with the dispenser unit 70 may be bent.

Accordingly, as illustrated in FIGS. 12 and 13, a protrusion 65 protruding from the rear surface of the front plate 60 along a circumference of the opening 61 may be provided at the rear surface of the front plate 60.

The protrusion 65 may be provided to have a width of approximately 30 mm from the opening 61, and to protrude approximately 0.45 mm from the rear surface of the front plate 60.

Since the protrusion 65 is provided along the circumference of the opening 61, when the dispenser unit 70 is coupled to the rear surface of the front plate 60, bends occurring at the surroundings of the opening 61 of the front plate 60 may be improved.

The process of coupling the dispenser unit 70 to the front plate 60 will be described. First, the gasket 80 is inserted into the insertion groove 75 of the dispenser unit 70 as illustrated in FIG. 3, and then the dispenser unit 70 is pressed against the rear surface of the front plate 60 as illustrated in FIG. 4.

Here, as illustrated in FIG. 7, the dispenser unit 70 is pressed against the rear surface of the front plate 60 by the fixing holes 77 being inserted into the hooks 63 of the front plate 60.

After the dispenser unit 70 is pressed against the rear surface of the front plate 60 by the hooks 63 being inserted into the fixing holes 77, the dispenser unit 70 is fixed to the front plate 60 by bending the hooks 63, and the fixing holes 77 are covered by the cap 90 to be sealed as illustrated in FIGS. 8 and 9.

While the refrigerator is mainly described with specific shapes and directions with reference to the accompanying drawings, various alterations and changes may be made by those skilled in the art, and it should be interpreted that the various alterations and changes fall within the scope of the appended claims.
