Referring to
The main cover 31 may further include a first rib 315 protruding downward and a second rib 317 protruding downward while being spaced apart from the first rib 315 by a predetermined distance. A first hollow part 41a, which is open downward, is provided between the first rib 315 and the second rib 317.
The auxiliary cover 35 is provided under the main cover 31. The auxiliary cover 35 may include a third rib 351 protruding upward and a fourth rib 353 protruding upward while being spaced apart from the third rib 351 by a predetermined distance. A second hollow part 41b, which is open upward, is provided between the third rib 351 and the fourth rib 353.
When the auxiliary cover 35 is fastened to the lower part of the main cover 31, therefore, the first hollow part 41a and the second hollow part 41b constitute a single hollow part 41.
Hereinafter, a structure in which the auxiliary cover 35 is fastened to the main cover 31 will be described.
The cover 3 may further include a hook 353a protruding from the fourth rib 353 and a hook hole 317a formed through the second rib 317 such that the hook 353a is inserted through the hook hole 317a. Alternatively, a hook recess may be provided in place of the hook hole 317a such that the hook 353a is inserted into the hook recess.
Consequently, the hook 353a may be inserted and fixed through the hook hole 317a in order to fasten the auxiliary cover 35 to the main cover 31.
Alternatively, the hook 353a may be provided at the second rib 317, and the hook hole 317a may be provided at the fourth rib 353.
Meanwhile, in a state in which the auxiliary cover 35 is fastened to the main cover 31, the first rib 315 and the third rib 351 may be spaced apart from each other by a predetermined distance. The first rib 315 and the third rib 351 constitute a through port 43. The through port 43 communicates with the hollow part 41.
Meanwhile, the gasket 33 may include a body 333 provided in the hollow part 41 and a protrusion 331 connected to the body 333 so as to protrude through the through port 43.
The body 333, provided in the hollow part 41, serves to support the protrusion 331.
Meanwhile, the protrusion 331 is brought into contact with the inner wall of the storage compartment 11 so as to prevent the leakage of the water stored in the storage compartment 11 to the outside. In addition, the protrusion 331 prevents the cover 3 from being separated from the storage unit 251 thanks to force with which the protrusion 331 pushes the inner wall of the storage compartment 11.
In other words, the protrusion 331 applies force to the inner wall of the storage compartment 11 to push the inner wall of the storage compartment 11. As a result, the protrusion 331 prevents water from leaking between the storage compartment 11 and the cover 3 and, prevents the cover 3 from being separated from the storage unit 251, due to the rattling of the door or splashing of the water when the door is opened or closed.
In addition, the protrusion 331 includes a recess 331a that is concave toward the body 333 and two contact parts 331b that are brought into contact with the inside wall of the storage compartment 11 in a state in which the recess 331a is interposed between the contact parts 331b.
When the cover 3 covers the opening 2513, therefore, the contact parts 331b press the inside wall of the storage compartment 11, and an air layer defined in the recess 331a, interposed between the contact parts 331b, prevents the water stored in the storage unit 251 from leaking to the outside.
In addition, the gasket 33 may be made of an elastic material that exhibits high elasticity. For example, the gasket 33 may be made of rubber.
In some implementations, the protrusion 331 may have a predetermined length such that the cover 3 is forcibly fitted in the opening 2513.
Hereinafter, the cover 3 included in the refrigerator 100 will be described in more detail with reference to
The cover 3 includes an insertion part 4 configured to be inserted into the storage unit 251 and a gasket 33 protruding from the insertion part 4 for sealing a gap defined between the inside wall of the storage unit 251 and the insertion part 4.
In addition, the cover 3 further includes a cover support part 313 protruding from the upper part of the insertion part 4. The cover support part 313 supports the cover at the upper part of the storage unit 251.
The gasket 33 may be made of an elastic material that exhibits high elasticity. For example, the gasket 33 may be made of rubber.
In addition, the gasket 33 includes a recess 331a that is concave and contact parts 331b that are brought into contact with the inside wall of the storage compartment 11 in a state in which the recess 331a is interposed between the contact parts 331b. When the contact parts 331b are brought into contact with the inside wall of the storage compartment 11, therefore, air is trapped in a space defined between the inside wall of the storage compartment 11 and the recess 331a.
In some implementations, the contact parts 331b may be forcibly fitted into the opening 2513 when the insertion part 4 is inserted into the opening 2513.
As a result, the water stored in the storage unit 251 is prevented from leaking to the outside, and the cover 3 is prevented from being separated from the storage unit 251, thanks to the air trapped in the space defined between the inside wall of the storage compartment 11 and the recess 331a.
In addition, the insertion part 4 has a hollow part 41 defined therein, and the insertion part 4 is provided at the side thereof with a through port 43, through which the hollow part 41 communicates with the outside.
In addition, the gasket 33 includes a protrusion 331 protruding through the through port 43 and a body 333 provided in the hollow part 41, the body 333 being connected to the protrusion 331.
In some implementations, the recess 331a and the contact parts 331b are provided at the protrusion 331.
The body 333, provided in the hollow part 41, serves to support the protrusion 331.
As is apparent from the above description, the refrigerator includes a water tank configured such that water is prevented from leaking from a space defined between a storage unit and a cover when a door is opened and closed.
In addition, the refrigerator includes a water tank configured such that a cover is prevented from being separated from a storage unit when a door is opened and closed.
