A refrigerator includes a refrigerator main body, a case forming a storage space with a front surface open, a drawer received in the case to be drawn out, a sealing apparatus having hooks disposed on the drawer and rotatable between a sealing position of maintaining a sealed state with being engaged with the case and a release position of releasing the engaged state with the case, and hook springs applying an elastic force to the hooks to be rotated to the sealing position, a manipulation handle rotatably disposed on the drawer and rotating the hooks to the release position when being pulled, and an operation bar to transfer a driving force of the manipulation handle to the hooks. Accordingly, reception and sealing of the drawer may be simultaneously realized and unsealing and drawing-out of the drawer may also be simultaneously realized.

1. A refrigerator comprising: a refrigerator body having a cooling chamber;a case disposed in the cooling chamber and forming a storage space with a front surface open;a drawer withdrawably received in the case;a sealing apparatus having hooks disposed on the drawer and rotatable between a sealing position in which the hooks engage with the case to provide a sealed state where the storage space of the case and the drawer received in the storage space are sealed from an outside and a release position in which the hooks disengage with the case to release the sealed state of the storage space of the case, and hook springs to apply an elastic force to the hooks to rotate to the sealing position;a manipulation handle rotatably disposed on the drawer to rotate the hooks to the release position when the manipulation handle is pulled;an operation bar interposed between the manipulation handle and the hooks to transfer a driving force of the manipulation handle to the hooks; anda communicating portion disposed at the drawer, the communicating portion having an opening and closing member,wherein the opening and closing member opens when the hooks are rotated to the release position, thereby the storage space of the case communicates with the outside. 2. The refrigerator of claim 1, wherein the hooks are disposed on two opposing sides of the drawer. 3. The refrigerator of claim 1, wherein the manipulation handle comprises an anti-sliding part on a surface facing the drawer. 4. The refrigerator of claim 1, wherein the drawer comprises a manipulation handle receiving portion to rotatably receive the manipulation handle. 5. The refrigerator of claim 1, wherein the drawer comprises a guide in which at least a portion of the operation bar is disposed, to guide the operation bar to slide backward and forward within the guide. 6. The refrigerator of claim 5, further comprising at least one elastic member to apply an elastic force to rotate the manipulation handle back to an original position after the manipulation handle is pulled. 7. The refrigerator of claim 6, wherein the manipulation handle comprises a pressing part contactable with the operation bar to press the operation bar. 8. The refrigerator of claim 7, wherein the at least one elastic member is disposed to press the operation bar toward the manipulation handle. 9. The refrigerator of claim 4, wherein the manipulation handle is disposed in the manipulation handle receiving portion to rotate in one of upward or downward direction when the manipulation handle is pulled. 10. The refrigerator of claim 1, wherein the case comprises a flange extending outwardly from the open front surface of the case, and the flange comprises stopping jaws to engage with corresponding hooks. 11. The refrigerator of claim 10, wherein the flange comprises a cut-off portion formed on a periphery of the stopping jaws, the cut-off portion being cut off for insertion of a corresponding hook therein. 12. The refrigerator of claim 11, wherein the cut-off portion of the flange has a width corresponding to an outermost end of the hook being located within an outer line of the flange when the hook is rotated to the release position. 13. The refrigerator of claim 10, wherein the stopping jaws comprise a protrusion protruding from a surface of the stopping jaws that engage with the corresponding hooks; and the corresponding hooks comprise a protrusion receiving portion having a contour corresponding to the protrusion of the stopping jaws. 14. The refrigerator of claim 10, wherein the hooks comprise a guide surface which when the guide surface comes in contact with the case, the guide surface guides the hooks to the release position. 15. The refrigerator of claim 14, wherein the guide surface is on an outer surface of a protruding end of the hooks, and the thickness of the protruding end gradually decreases along a protruding direction of the protruding end of the hooks corresponding to the guide surface. 16. The refrigerator of claim 10, further comprising a sealing member disposed on a contact area between the case and the drawer, wherein the hooks and the stopping jaws are engaged with each other in a state that the sealing member is pressed by a pressing force, which is applied by the drawer when the drawer is closed, so as to keep pressing the sealing member. 17. The refrigerator of claim 1, wherein the hooks comprise an arm and when the arm is rotated, the hooks rotate centered around a rotation shaft of the hooks, wherein the operating bar is contactable with the arm of the hooks, and rotates the arm of the hooks to rotate the hooks. 18. The refrigerator of claim 1, wherein the opening and closing member comprises an elastic portion to open and close the communicating portion; a supporting portion to support the elastic portion; a spring to apply an elastic force to the supporting portion; and an operation rod protruding from the supporting portion, which when engaged causes the elastic portion to open the communicating portion. 19. The refrigerator of claim 18, when the operating rod of the communicating portion abuts the operating bar and when the operating bar is engaged to rotate the hooks to the release position, the operating bar engages the operating rod of the communicating portion.
