- the heat sink plate 42 and the fan 43 may pass through the guide hole 34 , leaving the front side of the thermoelectric plate 41 to face the back side of the food defrosting device 30 .
- the food defrosting device 30 may be assembled with the thermoelectric module 40 .
- the food defrosting chamber 20 and the food defrosting device 30 may not be connected, except via the opening hole 33 controlled by the damper 35 ; therefore, heat generated in the food defrosting device 30 may not be transferred to the food defrosting chamber 20 during the defrosting process.
- the heat sink plate 42 and the fan 43 may be positioned inside the food defrosting device 30 through the guide hole 34 .
- the front side of the thermoelectric plate 41 may be positioned to face the back side of the food defrosting device 30 and configured to close the guide hole 34 .
- the embodiments are depicted as having only one damper 35 provided in the food defrosting device 30 .
- embodiments are not limited as to the number of the dampers, and a plurality of dampers 35 may be provided. As the number of damper 35 is increased, the heat transfer rate may be increased between the food defrosting device 30 and the food defrosting chamber 20 .
- the refrigerator 1 may further include a damper motor (not shown) configured to open and close the damper 35 by rotation of the damper motor.
- the refrigerator 1 may further include a controller 11 , which may be positioned in the body 10 , that controls the damper 35 and the thermoelectric module 40 .
- the controller 11 may be configured to control the refrigerator 1 to operate in several modes. If food defrosting is needed, the controller 11 may place the refrigerator in the defrosting mode, such that the food defrosting device 30 is operated. If food defrosting is not need, the controller 11 may control the operation of refrigerator 1 to be in the general cooling mode. If rapid cooling is needed, the controller 11 may control the refrigerator to be in the rapid cooling mode, such that food stored in the food defrosting device 30 may be cooled more rapidly.
- the heat generated by the thermoelectric module 40 may be supplied or circulated into the food defrosting device 30 .
- the heat supplied to the food defrosting device 30 must not leak into the food defrosting chamber 20 . Therefore, in the defrosting mode, the controller 11 may be configured to turn on the thermoelectric plate 41 and the fan 43 , and to close the damper 35 .
- the controller 11 may be configured to turn off the thermoelectric plate 41 and the fan 43 , and to open the damper 35 .
- the refrigerated air from refrigerator 1 may enter the food defrosting device 30 more rapidly, and may be exchanged with the heat inside of the food defrosting device 30 . That is, in the rapid cooling mode, the controller 11 may be configured to turn off the thermoelectric plate 41 , and to turn on the fan 43 and t o open the damper 35 .
- the refrigerator 1 may include the food defrosting chamber 20 , which may be divided from the food storage chamber 15 , and the food defrosting device 30 , which may be configured to slide into or out of the food defrosting chamber 20 . Therefore, it may be possible to reduce both the time required to defrost frozen food, as well as the time required to clean the kitchen.
- FIG. 5 a method for controlling a defrosting assembly of a refrigerator, such as the refrigerator 1 of FIGS. 1-4 , according to an embodiment will be described herein below.
- the controller 11 may control the thermoelectric plate 40 and the fan 43 to be on for a fixed or predetermined period of time. At that time, the controller 11 may control the damper 35 to close the opening hole 33 to prevent heat transfer between the food defrosting device 30 and the food defrosting chamber 20 .
- a user may select the general cooling mode.
- the controller 11 may control the thermoelectric plate 40 and the fan 43 to be off.
- the controller 11 may control the damper 35 to be open, such that the opening hole 33 transfers heat between the food defrosting device 30 and the food defrosting chamber 20 .
- the controller 11 may control the thermoelectric plate 40 to be off, the fan 43 to be on, and the damper 35 to be open. Because the fan 43 is turned on, heat transfer between the food defrosting device 30 and the food defrosting chamber 20 may be rapid.
- the controller 11 may receive a mode selection by a user. If the user mode selection is determined to be the defrost mode, the controller 11 may operate the food defrosting assembly in the defrost mode, in step S 502 .
- the controller 11 may start a timer to operate the thermoelectric plate 41 and the fan 43 for a fixed or predetermined period of time, in step S 504 .

- the controller 11 may then determine whether the fixed or predetermined period of time has expired. Once the fixed or predetermined time has expired, the process may move to step S 514 , and the controller 11 may turn off the thermoelectric plate 41 . Further, the controller 11 may turn off the fan 43 , in step S 516 .
- step S 518 the controller 11 may operate the food defrosting assembly in the general cooling mode.
- the controller 11 may control the thermoelectric plate 41 and the fan 43 , respectively, to be off.
- the controller 11 may control the damper 35 to be open to allow chilled air from the food storage chamber 15 to enter the food defrosting device 30 .
- the food defrosting device 30 may be used for general food storage.
- step S 526 if the user mode selection is determined to be the rapid cooling mode, the controller 11 may operate the food defrosting assembly in the rapid cooling mode.
- step 528 the controller 11 may control the thermoelectric plate 41 to be off.
- steps 530 and 532 the controller 11 may control the fan 43 to be on and the damper 35 to be open, respectively.
- the fan 43 may circulate chilled air faster through the open damper 35 from the food storage chamber 15 into the food defrosting device 30 .
- a refrigerator is disclosed herein, and more particularly, a refrigerator having a food defrosting chamber 20 divided from a food storage chamber, and further comprising a food defrosting device positioned in, and removable from, the food defrosting chamber 20 for performing the defrosting or cooling functions in a single space by supplying heat to an inside of the food defrosting device in a defrosting mode, and by supplying chilled air from an outside of the food defrosting device in a general cooling mode or a rapid cooling mode, using a thermoelectric module.
- 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.
