Claims46
A refrigerator, comprising:
- a main body having a refrigerating compartment;
- a cool air duct supplying cool air to the refrigerating compartment;
- and
- a sub storage compartment provided in the main body independently maintaining a temperature thereof with respect to the refrigerating compartment and being indirectly cooled or indirectly heated.
A refrigerator having:
- a main body including a refrigerating compartment;
- a cool air duct supplying cool air to the refrigerating compartment;
- and
- a sub storage compartment provided in the main body to independently maintain a temperature thereof with respect to the refrigerating compartment, the sub storage compartment comprising:
- a separate accommodating part having a space formed therein including an opening through which heat or is transferred;
- and
- a heat transferring member surrounding at least a part of the separate accommodating part, and transferring heat or to the separate accommodating part.
A refrigerator having:
- a main body including a refrigerating compartment;
- a cool air duct supplying cool air to the refrigerating compartment;
- and
- a sub storage compartment provided in the main body to independently maintain a temperature thereof with respect to the refrigerating compartment;
- a damper controlling cool air supply from the cool air duct to the sub storage compartment;
- a heater supplying heat to the sub storage compartment;
- and
- a control part determining a maximum temperature and an upper limit temperature based on a set temperature inputted for the sub storage compartment and turning off the heater so that the sub storage compartment is naturally cooled by a temperature difference between the sub storage compartment and the refrigerating compartment if the temperature of the sub storage compartment reaches the maximum temperature when the sub storage compartment is forcedly heated.
A refrigerator having:
- a main body including a refrigerating compartment;
- a cool air duct supplying cool air to the refrigerating compartment;
- a sub storage compartment provided in the main body to independently maintain a temperature thereof with respect to the refrigerating compartment;
- a damper controlling a cool air supply from the cool air duct to the sub storage compartment;
- a heater supplying heat to the sub storage compartment;
- and
- a control part determining a minimum temperature and a lower limit temperature based on a set temperature inputted for the sub storage compartment and closing the damper if the temperature of the sub storage compartment reaches the minimum temperature when the sub storage compartment is forcedly cooled.
An operating method for a refrigerator having a main body including a refrigerating compartment and a sub storage compartment provided inside the refrigerating compartment, the refrigerator having a cool air supplying part and a heat supplying part, comprising:
- receiving a set temperature for the sub storage compartment;
- determining a maximum temperature, an upper limit temperature, a minimum temperature and a lower limit temperature of the sub storage compartment based on the set temperature;
- sensing a temperature of the sub storage compartment;
- forcedly heating the sub storage compartment through the heat supplying part if the sensed temperature of the sub storage compartment is equal to or lower than the lower limit temperature;
- and
- stopping the forcedly heating of the sub storage compartment if the temperature of the sub storage compartment reaches the maximum temperature.
An operating method for a refrigerator having a main body including a refrigerating compartment and a sub storage compartment provided inside the refrigerating compartment, the refrigerator having a cool air supplying part and a heat supplying part, comprising:
- receiving a set temperature for the sub storage compartment;
- determining a maximum temperature, an upper limit temperature, a minimum temperature and a lower limit temperature of the sub storage compartment based on the set temperature;
- sensing a temperature of the sub storage compartment;
- forcedly cooling the sub storage compartment through the cool air supplying part if the sensed temperature of the sub storage compartment is equal to or higher than the upper limit temperature;
- and
- stopping the forcedly cooling of the sub storage compartment if the temperature of the sub storage compartment reaches the minimum temperature.
An operating method for a refrigerator having a main body including a refrigerating compartment and a sub storage compartment provided inside the refrigerating compartment, the refrigerator further having a cool air supplying part and a heat supplying part, comprising:
- receiving a set temperature for the sub storage compartment;
- determining a maximum temperature, an upper limit temperature, a minimum temperature and a lower limit temperature of the sub storage compartment based on the set temperature;
- sensing a temperature of the sub storage compartment;
- determining whether the refrigerating compartment is supplied with cool air if the sensed temperature of the sub storage compartment is equal to or lower than the lower limit temperature;
- and
- forcedly heating the sub storage compartment through the heat supplying part only if the refrigerating compartment is not supplied with cool air.
A refrigerator, comprising:
- a refrigerating compartment;
- a sub storage compartment;
- a cool air duct supplying cool air to the refrigerating compartment and the sub storage compartment;
- a damper controlling the supply of cool air from the cool air duct;
- a heater supplying heat to the sub storage compartment;
- and
- a control part controlling at least one of the damper and the heater to forcedly heat or forcedly cool the sub storage compartment.
The refrigerator according to claim 44, wherein the control part controls at least one of the damper and the heater based on a set temperature set for the sub storage compartment.
