Abstract

The present invention relates to a temperature-context-aware refrigerator and a method for controlling the same. A temperature-context-aware refrigerator according to an embodiment of the present invention 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 is required for the temperature context awareness unit to generate the load-responsive operation information.

First claim

The invention claimed is:

1. A refrigerator, comprising:
a first storage space;
one or more temperature sensors to detect a temperature of the first storage space;
a controller to:
generate first operation information identifying a second target temperature lower than a first target temperature set for the first storage space, the first operation information being generated based on the first target temperature and first temperature information detected by the one or more temperature sensors, and
perform a load responsive operation that includes controlling a temperature of the first storage space based on the first operation information; and

a communication interface to exchange 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 the 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;
a 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, history information related to operation of the refrigerator, setup information of the refrigerator to be changed according to the load responsive operation, or carry-in condition information including a temperature condition of an object positioned in the refrigerator.

2. The refrigerator of claim 1 ,
wherein, while the controller performs the load responsive operation based on the first operation information, the one or more temperature sensors further detect second temperature information identifying a temperature of the first storage space at a preset interval, and
wherein controller further determines whether to stop the load responsive operation based on the second temperature information detected by the one or more temperature sensors.

3. The refrigerator of claim 1 , further comprising:
a user interface that displays an operation condition according to the first operation information, the operation condition identifying the second target temperature.

4. The refrigerator of claim 1 , wherein the communication interface further transmits at least a portion of the first temperature information to an external device, and receives logic to generate the first operation information from the external device.

5. The refrigerator of claim 1 , further comprising:
a door sensor to detect whether of a door of the refrigerator is opening or closing the first storage space,
wherein the controller further determines whether to perform the load responsive operation according to opening or closing of the first storage space by the door.

6. The refrigerator of claim 5 ,
wherein the controller generates the first operation information when the first temperature information detected by the one or more temperature sensors indicates a change in a temperature of the first storage area within a particular period of time after the first storage space is opened and closed by the door.

7. The refrigerator of claim 1 ,
wherein the one or more temperature sensors further detect at least one of a temperature of an object positioned in the first storage space or a humidity in the first storage space, and
wherein the first operation information is further generated based on the at least one of the temperature of the object or the humidity in the first storage space.

8. The refrigerator of claim 1 , further comprising a second storage space that is separate from the first storage space,
wherein, the controller further generates second operation information for the second storage space while performing the load responsive operation according to the first operation information, and performs a second load responsive operation based on the second operation information.

9. The refrigerator of claim 1 ,
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 information on the screen.

10. A refrigerator comprising:
a first storage space;
one or more temperature sensors to detect a temperature of the first storage space;
a controller to:
generate first operation information identifying a second target temperature lower than a first target temperature set for the first storage space, the first operation information being generated based on the first target temperature and first temperature information detected by the one or more temperature sensors; and
perform a load responsive operation that includes controlling a temperature of the first storage space based on the first operation information; and

a communication interface to exchange data with a computer,
wherein the computer includes:
a computer communication interface to communicate with the refrigerator and a user device;
a computer memory to store information related to the load responsive operation; and
a computer controller that manages the computer communication interface and the computer memory to control the refrigerator in a context-aware manner,

wherein:
the computer communication interface receives a load responsive operation flag message related to the load responsive operation from the communication interface of the refrigerator,
the computer memory stores at least a portion of the load responsive operation flag message, and
the computer communication interface transmits a notification message notifying the user device of the load responsive operation of the refrigerator, and

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

11. The refrigerator of claim 10 , wherein:
the computer controller generates load responsive operation logic using one or more of a plurality of load responsive operation flag massages generated by a plurality of refrigerators, the computer communication interface transmits the load responsive operation logic to the communication interface of the refrigerator, and
the load responsive operation logic includes one or more of time information, temperature information, or humidity information used by the refrigerator to determine the load responsive operation.

12. The refrigerator of claim 11 ,
wherein the load responsive operation logic is configured differently according to at least one of a region where the refrigerator is installed or a model of the refrigerator.

13. The refrigerator of claim 10 , wherein the computer further:
receives identification information of the refrigerator and control information related to the load responsive operation corresponding to identification information from the user device, and
transmits the received control information related to the load responsive operation to the communication interface of the refrigerator.
