The thawing chamber door 62 is hinged to the front surface of the thawing chamber body 72 to have a rotatable structure.

The thawing chamber body 72 is formed of a heat insulating material to block heat transfer inside the thawing chamber body 72 and the outside of the thawing chamber body 72.

The thawing plate 74 is formed in a flat plate shape, is formed of a metal of a high thermal conductivity material, in this embodiment the thawing plate 74 is formed of aluminum.

The temperature sensor 76 is installed on the side wall of the thawing chamber body 72 to detect the surface temperature of the frozen water 1, and transmits the detected temperature to the controller of the refrigerator.

On the other hand, the lower side of the thawing plate 74 is provided with a pressure sensor 78 for sensing the weight of the frozen water (1).

The thawing pack 80 is made of a flexible material to be in direct contact with the frozen water 1 to cause heat exchange, and is heated by the heating device 90 so that the frozen water 1 is connected to the heating device 90. To prevent direct heating. In the present embodiment, the thawing pack 80 is formed of an aluminum material so that the thawing pack 80 is flexible to be in close contact with the frozen water with high thermal conductivity.

The heating apparatus 90 fixes the hot wire coil 92 that generates heat by an applied current, the glass tube 94 surrounding the hot coil 92, and the glass tube 94 to the thawing chamber body 72. It is configured to include a bracket (96).

The blower 100 divides the fan 102, the motor 104 for driving the fan 102, and the inner space of the thawing chamber body 72 in a vertical direction so that air can be distributed. The grill 106 includes a plurality of holes 105, and a bracket 108 for fixing the motor 104 to the grill 106.

Here, the fan 102 is installed in the upper center of the thawing chamber body 72 to flow the air heated by the heating device 90 to the frozen water (1).

And the bracket 108 is formed of a material capable of absorbing the vibration of the motor 104 to suppress the vibration generated in the motor 104 is transmitted to the thawing chamber body (72).

In addition, although the thawing chamber body 72 is presented as a separate member that is distinguished from the main body 10 in the present embodiment, the thawing chamber body 72 and the main body 10 may be manufactured integrally. It's okay.

The cold air supply passage 150 is connected to the freezing chamber 30 to receive cold air.

The opening and closing mechanism 160 includes a plate 162 for opening and closing the cold air inflow passage 150, a rotation shaft 164 fixed to the plate 162 to rotate the plate 162, and the rotation shaft 164. It is configured to include a motor (not shown) for operating.

Here, by the operation of the opening and closing mechanism 160, the cold air introduced through the cold air supply passage 150 is intermittent.

Hereinafter, a control method of the refrigerator thawing room unit according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

First, the user removes the frozen water 1 of the freezing chamber 30 and inserts it into the thawing pack 80 of the thawing chamber 60, closes the thawing chamber door 62, and then reserves the thawing chamber 60. Select the function (S10).

Here, the user selects the type and the thawing completion time of the frozen water (1) by pressing the operation button (not shown) to operate the thawing room unit 70. (S20)

Thereafter, the controller of the refrigerator detects the weight of the frozen water 1 placed on the thawing plate 74 through the pressure sensor 78 and adjusts the temperature of the frozen water 1 through the temperature sensor 76. Sense (S30)

The controller determines the thawing time required for the frozen product by referring to previously stored data through an experiment.

That is, the thawing time is increased in the case of the frozen water containing a large amount of water, and the thawing time is shortened in the case of the frozen water containing a small amount of water, and these data are previously stored in the controller through experiments.

The control unit calculates the difference between the completion time selected by the user and the current time, and compares the thawing time determined by the control unit (S50). Activate (S60)

On the other hand, if the difference between the completion time selected by the user and the current time is larger than the thawing time, there is a spare time necessary for thawing, and the frozen water 1 is kept in a refrigerated or frozen state until the thawing time is required. (S70)

When the current time reaches the thawing start time according to the thawing time after the maintenance step S70 (S75), the thawing chamber unit 70 is operated to defrost the frozen water 1 (S60).

On the other hand, when the current time does not reach the thaw start time according to the thawing time, the process returns to the holding step (S70).

When the thawing of the frozen water 1 is completed by the thawing step 60 (S80), the display device (not shown) of the refrigerator indicates that thawing is completed. (S90)

In addition, in order to prevent the user from taking out the frozen water 1, the thawing chamber unit 70 is operated to maintain the thawed frozen water 1 at an appropriate temperature.

Hereinafter, the operation process of the thawing chamber unit in the thawing step (S60) is as follows.

When the thawing chamber unit 70 is operated, the heating device 90 and the blowing device 100 are operated, and the air heated by the heating device 90 is defrosted by the blowing device 100. The body 72 is circulated inside.

In addition, the heated air is heat-exchanged with the thawing plate 74 and the thawing pack 80, and the frozen water 1 is heat-exchanged with the thawing pack 80 to gradually increase the temperature.

In this case, the controller controls the heating device 90 and the blower 100 so as to prevent the temperature of the frozen product 1 from being rapidly raised by sensing the temperature of the frozen product 1 from time to time.

When the frozen matter 1 is completely thawed, problems such as breeding of microorganisms or deformation of the frozen matter occur, and preferably -2 ° C to -3 ° C.

On the other hand, look at the operation process of the thawing chamber unit in the holding step (S70) as follows.

First, the control unit senses the temperature of the frozen water 1 through the temperature sensor 76, when the detected temperature is more than a predetermined temperature, by operating the opening and closing mechanism 160 to open the cold air supply passage 150 Open.

Here, the control unit rotates the plate 162 by applying a current to the motor, and adjusts the amount of cold air introduced into the thawing chamber body 72 according to the rotation angle of the plate 162.

Thus, the control unit maintains the frozen matter 1 at a predetermined temperature until the thawing start time.

4 is a flowchart illustrating a control method of a thawing room unit according to a second exemplary embodiment of the present invention.

The second embodiment enters the thawing step 60 immediately after the thawing time calculation step S40 except for the time comparison step S50 in the first embodiment.

That is, the second embodiment does not thaw after waiting until the completion time, but immediately after thawing time calculation, and thaw the frozen product at a predetermined temperature when thawing of the frozen product is completed.

In addition, since the control method according to the second embodiment is the same as the first embodiment, a detailed description thereof will be omitted.

The thawing room unit control method of the refrigerator according to the present invention configured and operated as described above has an advantage of improving the convenience of the user because the user defrosts the frozen water according to the completion time when the thaw is reserved. have.

In addition, the method of controlling the thawing chamber unit of the refrigerator according to the present invention has an advantage of suppressing deterioration of the thawed frozen product because the frozen product is maintained at an appropriate temperature even after thawing is completed.

In addition, the method of controlling the thawing room unit of the refrigerator according to the present invention has an advantage of illuminating the user's attention because it notifies the user after the thawing is completed.

In addition, the thawing room unit control method of the refrigerator according to the present invention has the advantage of thawing the frozen water more efficiently because it determines the thawing time of the frozen water according to the type and weight of the frozen water.
