Abstract

Claims (39)

1 . A cooking apparatus comprising:

a cooking module configured to perform a cooking operation by heating an object to be heated;

a communication module configured to communicate with a user terminal;

a memory; and

at least one processor configured to:

control the cooking module to perform the cooking operation based on a control command received from the user terminal,

control the cooking module to stop the cooking operation in response to disconnection of communication with the user terminal,

determine cooking status information at a time when the communication with the user terminal is disconnected, and

store the cooking status information in the memory.

2 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to:

control the communication module to transmit cooking status information to the user terminal, and

determine the communication with the user terminal as being disconnected in response to a failure of receiving acknowledgment (ACK) from the user terminal.

3 . The cooking apparatus of claim 2 , wherein the at least one processor is further configured to control the communication module to retransmit the cooking status information a preset number of times in response to the failure of receiving the ACK from the user terminal.

4 . The cooking apparatus of claim 3 , wherein the at least one processor is further configured to determine the communication with the user terminal as being disconnected in response to a failure of receiving the ACK after the retransmission of the cooking status information.

5 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to determine the communication with the user terminal as being disconnected in response to a failure of receiving a communication signal for a preset period of time from an access point (AP) which relays communication with the user terminal.

6 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to determine the communication with the user terminal as being disconnected in response to reception of information about disconnection of the communication with the user terminal from an external server.

7 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to send an off signal to the cooking module to stop the cooking operation in response to disconnection of the communication with the user terminal.

8 . The cooking apparatus of claim 1 , further comprising:

a valve configured to open or close a gas supply tube connected to the cooking module,

wherein the at least one processor is further configured to control the valve to close the gas supply tube to stop the cooking operation in response to disconnection of the communication with the user terminal.

9 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to control the cooking module to stop the cooking operation after elapse of a preset period of time depending on a cooking progress stage in response to disconnection of the communication with the user terminal.

10 . The cooking apparatus of claim 9 , wherein the at least one processor is further configured to:

determine an ongoing time section among a plurality of time sections of a whole cooking time in response to disconnection of the communication with the user terminal; and

control the cooking module to stop the cooking operation after elapse of the preset period of time corresponding to the determined time section.

11 . The cooking apparatus of claim 10 , wherein the at least one processor is further configured to control the communication module to try communication with the user terminal a preset number of times before controlling the cooking module to stop the cooking operation after elapse of the preset period of time.

12 . The cooking apparatus of claim 1 , wherein the at least one processor is further configured to:

control the cooking module to resume the cooking operation based on the cooking status information in response to restoration of connection of communication with the user terminal.

13 . The cooking apparatus of claim 12 , wherein the at least one processor is further configured to:

control the communication module to transmit, to the user terminal, a message confirming whether to resume the cooking operation in response to restoration of connection of the communication with the user terminal, and

control the cooking module to resume the cooking operation in response to reception of a command to resume the cooking operation from the user terminal.

14 . The cooking apparatus of claim 12 , wherein the at least one processor is further configured to:

determine a remaining cooking time of a set cooking time based on the cooking status information in response to restoration of connection of the communication with the user terminal, and

control the cooking module to perform the cooking operation for the remaining cooking time.

15 . A method of controlling a cooking apparatus including a cooking module for performing a cooking operation by heating an object to be cooked and a communication module for communicating with a user terminal, the method comprising:

controlling the cooking module to perform the cooking operation based on a control command received from the user terminal;

controlling the cooking module to stop the cooking operation in response to disconnection of communication with the user terminal;

determining cooking status information at a time when the communication with the user terminal is disconnected; and

storing the cooking status information in memory.

16 . The method of claim 15 , wherein the cooking status information includes at least one of: information about a cooking mode, a temperature set for cooking, a time set for cooking, a cooking start time, a cooking progress time, a remaining cooking time, or a temperature in the cooking module.
