The damper 70 allows the freezing chamber 23 and the refrigerating chamber 21 to be cooled independently by one evaporator 43 and one fan 45. In other words, the temperature of the freezing compartment 23 and the refrigerating compartment 21 can be adjusted independently by receiving cold air independently from the damper 70 even by a single fan 45. Accordingly, the freezer compartment 23 can be conveniently used for the same purposes as the refrigerator compartment 21 by controlling the damper 70 so that the temperature of the freezer compartment 23 is as high as the temperature of the refrigerator compartment 21 as needed. Because of this, consumer convenience can be improved. (See Figure 2) A detailed description of this will be given below.

The damper 70 may be provided as a 2-way damper. Because a 2-way damper is used, the

flow paths

53, 55, and 57 can be configured in a simple and small size. That is, because the configuration of the

flow paths

flow paths

55 and 57. Since it can have the function of independently cooling the freezer compartment 21 and the refrigerator compartment 21, the presence or absence of the function of independently cooling the freezer compartment 23 and the refrigerator compartment 21 can be selected by replacing the freezer cold air duct 50. You can.

Next, with reference to Figures 7 to 14, let's take a closer look at the operation of the refrigerator in various modes according to the control of the damper. In the following, the freezer compartment 23 and the refrigerator compartment 21 will be described with reference to FIG. 2.

FIG. 7 is a diagram illustrating how, when a refrigerator according to an embodiment is used in the first mode, a damper opens both the refrigerating compartment flow path and the freezer compartment flow path so that cold air moves into the refrigerating chamber flow path and the freezer flow path. Figure 8 is a diagram showing the movement path of cold air when the damper is controlled as shown in Figure 7. FIG. 9 is a diagram illustrating when the refrigerator according to one embodiment is used in the second mode, the damper opens the refrigerating compartment passage and closes the freezer compartment passage, so that cold air moves only into the refrigerating compartment passage. Figure 10 is a diagram showing the movement path of cold air when the damper is controlled as shown in Figure 9. FIG. 11 is a diagram illustrating how, when the refrigerator according to one embodiment is used in the third mode, the damper closes the refrigerator compartment flow path and opens the freezer compartment flow path, so that cold air moves only into the freezer compartment flow path. Figure 12 is a diagram showing the movement path of cold air when the damper is controlled as in Figure 11. FIG. 13 is a diagram illustrating how cold air moves when a damper opens the refrigerator compartment flow path and repeatedly opens and closes the freezer compartment flow path when the refrigerator according to one embodiment is used in the fourth mode. FIG. 14 is a diagram illustrating the movement of cold air when a damper closes the refrigerator compartment flow path and repeatedly opens and closes the freezer compartment flow path when the refrigerator according to one embodiment is used in the fifth mode.

The refrigerator can be used in various modes according to the control of the damper 70.

As shown in Figures 7 and 8, the refrigerator can be used in a first mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for freezing and refrigeration, respectively. The first mode of the refrigerator may be a general mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for their original purposes.

When the refrigerator is used in the first mode, the damper 70 can be controlled to open both the refrigerator compartment flow path 55 and the freezer compartment flow path 57. That is, the damper 70 can be controlled so that the first opening and closing plate 75 and the second opening and closing plate 76 open the first opening 72 and the second opening 73. When both the first opening 72 and the second opening 73 are opened, cold air can be supplied to the freezing compartment 23 and the refrigerating compartment 21.

As shown in Figures 9 and 10, the refrigerator can be used in a second mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for off and refrigeration, respectively. The second mode of the refrigerator may be a mode in which the freezer compartment 23 is turned off to save energy when the freezer compartment 23 is not in use.

When the refrigerator is used in the first mode and then switched to the second mode, the damper 70 may be controlled so that the refrigerator compartment passage 55 remains open and the freezer compartment passage 57 is closed. That is, the damper 70 can be controlled so that the first opening and closing plate 75 maintains the first opening 72 in an open state, and the second opening and closing plate 76 closes the second opening 73. . Because the first opening 72 is open, cold air can be supplied to the refrigerating compartment 21. In other words, the refrigerating compartment 21 can be used for its original purpose. However, because the second opening 73 is closed, cold air is not supplied to the freezer compartment 23 and the freezer compartment 23 may be turned off. In order to convert the freezer compartment 23 back to use for refrigeration, the damper 70 opens the freezer compartment flow path 57 and can be controlled to maintain the freezer compartment flow path 57 in an open state.

As shown in Figures 11 and 12, the refrigerator can be used in a third mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for freezing and off, respectively. The third mode of the refrigerator may be a mode in which only the freezer 23 is used without using the refrigerator 21 in order to store food for a long time when leaving the house for a long period of time due to a vacation or the like.

When the refrigerator is used in the first mode and then switched to the third mode, the damper 70 may be controlled to close the refrigerator compartment passage 55 and keep the freezer compartment passage 57 open. That is, the damper 70 can be controlled so that the first opening and closing plate 75 closes the first opening 72 and the second opening and closing plate 76 opens the second opening 73. . Since the second opening 73 is open, cold air can be supplied to the freezing chamber 23. That is, the freezer 23 can be used for its original purpose. However, because the first opening 72 is closed, cold air is not supplied to the refrigerating compartment 21 and the refrigerating compartment 21 may be turned off.

As shown in FIG. 13, the refrigerator can be used in a fourth mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for refrigeration and refrigeration, respectively. The fourth mode of the refrigerator may be a mode in which both the freezer compartment 23 and the refrigerator compartment 21 can be used as the refrigerator compartment 21 when there is a lot of food to be stored in the refrigerator compartment 21.

When the refrigerator is used in the first mode and then switched to the fourth mode, the damper 70 may be controlled so that the refrigerator compartment passage 55 remains open and the freezer compartment passage 57 is closed. That is, the damper 70 can be controlled so that the first opening and closing plate 75 maintains the first opening 72 in an open state, and the second opening and closing plate 76 closes the second opening 73. . Because the first opening 72 is open, cold air can be supplied to the refrigerating compartment 21. In other words, the refrigerating compartment 21 can be used for its original purpose.

When the freezer passage 57 is closed, cold air is not supplied to the freezer compartment 23, and the temperature of the freezer compartment 23 may increase. When the temperature of the freezer compartment 23 increases to the temperature used for refrigeration, which is the same temperature as the refrigerator compartment 21, the damper 70 is controlled so that the second opening and closing plate 76 repeats the opening and closing of the second opening 73. You can. That is, by repeatedly opening and closing the freezer compartment flow path 57 to control the amount of cold air supplied to the freezer compartment 23, the temperature at which the freezer compartment 23 is used for refrigeration can be maintained. In order to switch the freezer compartment 23 back to being used for refrigeration, the damper 70 may be controlled to continuously open the freezer compartment passage 57.

As shown in FIG. 14, the refrigerator can be used in a fifth mode in which the freezer compartment 23 and the refrigerator compartment 21 are used for refrigeration and off, respectively. The fifth mode of the refrigerator uses the refrigerator only as a refrigerator compartment (21), but when the amount of food to be stored is small, the relatively large refrigerator compartment (21) is not used, and the small freezer compartment (23) is used as the refrigerator compartment (21). ) may be a mode used by switching to ).

When the refrigerator is used in the first mode and then switched to the fifth mode, the damper 70 may be controlled so that both the refrigerator compartment flow path 55 and the freezer compartment flow path 57 are closed. That is, the damper 70 can be controlled so that the first opening and closing plate 75 and the second opening and closing plate 76 close the first opening 72 and the second opening 73. Since both the first opening 72 and the second opening 73 are closed, cold air may not be supplied to the refrigerator compartment 21 and the freezer compartment 23. Since cold air is not supplied to both the refrigerator compartment 21 and the freezer compartment 23, both the refrigerator compartment 21 and the freezer compartment 23 may be turned off.

In the above description of the refrigerator with reference to the attached drawings, the specific shape and direction have been mainly explained. However, various modifications and changes can be made by those skilled in the art, and such modifications and changes are included in the scope of rights of the disclosed invention. must be interpreted.
