Abstract

A temperature-context-aware refrigerator according to an embodiment comprises: a temperature context awareness unit for sensing a temperature of at least one storage compartment, and when the difference between the sensed temperature and a temperature set for the corresponding storage compartment is equal to or greater than a predetermined level, generating load-responsive operation information including a target temperature lower or higher than the set temperature; a temperature control unit for controlling a temperature sensor and the temperature context awareness unit, and performing a load-responsive operation for controlling the temperature of the storage compartment by using the load-responsive operation information; and a database unit which used by the temperature context awareness unit to generate the load-responsive operation information.

First claim

The invention claimed is:

1. A refrigerator comprising:
a storage space;
a first sensor to detect a temperature of the storage space;
a second sensor to detect when an object is placed into the storage space;
a communication interface;
a controller to:
set a target temperature to one of a first temperature or a second temperature that is higher than the first temperature when the first sensor detects a change in the temperature of the storage space, the controller setting the target temperature to the first temperature when the second sensor detects the object being placed into the storage space during a particular time period before the change in the temperature of the storage space, and setting the target temperature to the second temperature when the second sensor does not detect the object being placed into the storage space during the particular time period before the change in the temperature of the storage space,
control a temperature of the storage space based on the target temperature, and
forward, via the communication interface, a message to another device, the message identifying at least one of a current condition of the refrigerator, history information related to operation of the refrigerator, setup information of the refrigerator, or information identifying an attribute of the object.

2. The refrigerator of claim 1 , wherein the controller is further to receive, via the communication interface, logic from the other device to select the target temperature, and
wherein the logic identifies at least one of time information, temperature information, or humidity information used by the controller to select the target temperature.

3. The refrigerator of claim 1 , wherein, after the target temperature is set to the first temperature, the controller is further to change the target temperature from the first temperature based on at least one of:
the first sensor determining that the temperature of the storage space is in a particular range of temperatures,
the temperature of the storage space being controlled based on the target temperature being set to the first temperature for a particular duration of time, or
an instruction to set the target temperature to the second temperature being received from a user interface included in the refrigerator or from the other device via the communication interface.

4. The refrigerator of claim 1 , wherein the second sensor includes:
a door sensor to detect when a door is opening or closing the storage space,
wherein controller sets the target temperature to the first temperature when the first sensor detects the change in the temperature of the storage space during the particular time period after the door sensor detects that the door has opened and closed the storage space.

5. The refrigerator of claim 1 , wherein the controller further changes the target temperature for the storage space based on receiving, via the communication interface, an instruction from the other device.

6. The refrigerator of claim 1 , wherein the controller sets the target temperature for the storage space to the first temperature based on determining that the target temperature has not been set to the first temperature or lower more than a prescribed number of times during a prescribed time.

7. The refrigerator of claim 1 ,
wherein the controller generates first operation information for the storage space,
wherein the first operation information is generated based on the target temperature, and
wherein the controller performs a load responsive operation that includes controlling a temperature of the storage space based on the first operation information.

8. The refrigerator of claim 7 ,
wherein, while the controller performs the load responsive operation based on the first operation information, the first sensor further detects temperature information identifying the temperature of the storage space at a preset interval, and
wherein controller further determines whether to stop the load responsive operation based on the temperature information detected by the first sensor.

9. The refrigerator of claim 7 , further comprising:
a user interface that displays an operation condition according to the first operation information, the operation condition identifying the target temperature.

10. The refrigerator of claim 7 , wherein the communication interface further transmits at least a portion of a temperature information detected by the first sensor to an external device, and receives logic to generate the first operation information from the external device.

11. The refrigerator of claim 7 , further comprising:
a door sensor to detect whether of a door of the refrigerator is opening or closing the storage space,
wherein the controller further determines whether to perform the load responsive operation according to opening or closing of the storage space by the door.

12. The refrigerator of claim 11 , wherein the controller generates the first operation information when temperature information detected by the first sensor indicates a change in the temperature of the storage area within a particular period of time after the storage space is opened and closed by the door.

13. The refrigerator of claim 7 ,
wherein the first sensor further detects at least one of a temperature of the object positioned in the storage space or a humidity in the storage space, and
wherein the first operation information is generated further based on the at least one of the temperature of the object or the humidity in the first storage space.

14. The refrigerator of claim 7 , wherein the storage space is a first storage space, and the load responsive operation is a first load responsive operation,
wherein the refrigerator further comprises a second storage space that is separate from the first storage space, and
wherein, the controller further generates second operation information while performing the load responsive operation according to the first operation information, and performs a second load responsive operation for the second storage space based on the second operation information.

15. The refrigerator of claim 7 , wherein the communication interface exchanges data with a user device,
wherein the user device includes:
a user device memory to store an application that controls the load responsive operation of a refrigerator;
a user device communication interface to transmit a setup condition set generated by the application to a computer and to receive a notification message related to the load responsive operation of the refrigerator from the computer;
user device user interface to output data associated with the application; and
a user device controller to execute the application and control the user device communication interface and the user device user interface, and

wherein the notification message includes one or more of current condition information of the load responsive operation of the refrigerator, the history information related to operation of the refrigerator, the setup information of the refrigerator to be changed according to the load responsive operation, or carry-in condition information including a temperature condition of the object positioned in the refrigerator.

16. The refrigerator of claim 15 , wherein the user device user interface displays a message received via the user device communication interface on a screen in a pop-up form, and
wherein the user device user interface further displays at least one of the current condition information, the history information, the setup information, or the carry-in condition informatio
