The first vibration reducing member 141 may be a little thick to closely contact the neck portion of the wine bottle 50. That is, in a state where the wine bottle 50 is held to the holder 130, the neck portion of the wine bottle 50 may closely contact the holder 130 by the first vibration reducing member 141.
Meanwhile, the second vibration reducing member 142 may be formed to closely contact the lower portion of the wine bottle 50. In general, since the lower portion of the wine bottle has a radius larger than the neck portion, the second vibration reducing member 142 will be able to have a thickness thinner than the first vibration reducing member 141.
However, the sizes and shapes of the vibration reducing members 141 and 142 are not limited to any one. If the upper portion and the lower portion of the wine bottle 50 can closely contact the holder 130 with ease, various embodiments may be proposed.
The vibration reducing members 141 and 142 may be made of a rubber or sponge material so as to absorb predetermined vibration and may be attached to the holder 130.
Meanwhile, in the embodiment, although the vibration reducing members are provided in the upper portion and the lower portion of the holder 130, the vibration reducing members may be provided at another position or throughout the entire surface of the holder 130.
Further, the vibration reducing member may be interposed between the basket 120 and the holder 130. In this case, while the basket 120 is drawn in and out, vibration generated between the basket 120 and the holder 130 will be able to be absorbed in the vibration reducing members.
FIG. 6 is a block diagram showing a configuration of a refrigerator according to a first embodiment of the present invention.
Referring to FIG. 6, the refrigerator 1 according to the first embodiment of the present invention includes a first input unit 161 and a second input unit 162 that can be selectively operated depending on the kind of stored wine, a memory 164 that memorizes a preset temperature value by inputting a command in the input units 161 and 162, a display unit 163 that displays the command inputted by the input units 161 and 162, a temperature sensing unit 160 that senses the temperature of the storage chamber 102 of the wine storage compartment 100, a cool air supplying unit 165 that is provided in the storage chamber 102 and selectively supplies cool air depending on a value sensed by the temperature sensing unit 160, and a control unit 170 that controls operations of the components 160, 161, 162, 163, and 165.
More specifically, the input units 161 and 162 can be selectively operated depending on the kind of wine. For example, when the stored wine is white wine, the first input unit 161 can be selected and when the stored wine is red wine, the second input unit 162 can be selected.
In general, the white wine is preferably stored in the range of approximately 10° C. to 15° C. and the red wine is preferably stored in the range of approximately 15° C. to 20° C.
Therefore, when the white wine is selected through the first input unit 161, the temperature of the storage chamber 102 can be controlled to be maintained at any one value in the range of 10° C. to 15° C., i.e., approximately 12° C. In contrast, when the red wine is selected through the second input unit 162, the temperature of the storage chamber 102 can be controlled to be maintained at any one value in the range of 15 to 20° C., i.e., approximately 18° C.
Of course, the temperature value (12° C., 18° C., or others) that should be maintained depending on the kind of wine may be previously set and the set temperature value may be memorized in the memory 164.
Although not shown in the figure, the refrigerator may further include another input unit that allows the user to directly input the set temperature of the storage chamber 102 except for the input units 161 and 162.
When a predetermined command is inputted by the input units 161 and 162, the kind of stored wine may be displayed on the display unit 163 on the basis of the inputted command. In addition, the temperature value stored in the memory 164 may be displayed on the display unit 163 depending on the kind of wine.
The temperature sensing unit 160 senses the internal temperature of the storage chamber 102 and transfers the result to the control unit 170. The control unit 170 can compare a current temperature value sensed by the temperature sensing unit 160 with a predetermined set temperature in accordance with the command inputted by the input units 161 and 162.
If the set temperature value is lower than the current temperature value, the control unit 170 opens the cool air supplying unit 165 to supply the cool air to the storage chamber 102.
In contrast, if the set temperature value is higher than the current temperature value, the control unit 170 closes the cool air supplying unit 165 to stop supplying the cool air.
Further, a heater 168 for increasing the internal temperature of the storage chamber 102 can be provided in the storage chamber 102. When the set temperature value is higher than the current temperature value, the heater 168 is activated to transfer predetermined heat to the storage chamber 102, such that the temperature of the storage chamber 102 can be increased to the set temperature.
As described above, since the temperature of the storage chamber 102 of the wine storage compartment 100 can be controlled independently from the refrigerating chamber and the freezing chamber, wine can be stored under the optimal temperature condition.
Hereinafter, a second embodiment of the present invention will be described. Since the second embodiment has the difference in the configuration of the wine storage compartment as compared to the first embodiment, the difference will mainly be described and the same elements as the first embodiment refer to the same descriptions and reference numerals of the first embodiment.
