For data communication with the first server 510a, if a data structure of a predetermined format is defined, the first interface 272 may perform data conversion according to the defined data structure such that data exchange is possible.

For data conversion, the first interface 272 may include an agent for the first server 510a.

Next, when Wi-Fi communication with the AP apparatus 400 is performed, the communication unit 222 may include a Wi-Fi communication module and the second interface 274 may include a Wi-Fi application 274 for data exchange between the controller 270 and the AP apparatus 400. Thus, data conversion, etc. may be performed.

For data exchange with the server, data output from the controller 270 may be subjected to primary data conversion in the Wi-Fi application 274, may be subjected to secondary data conversion in the agent 272 for the first server 510a, and may be transmitted to the first server 510 via the AP apparatus 400, and vice versa.

Data which is not related to the first server 510a may be subjected to primary data conversion in the Wi-Fi application 274 without conversion by the agent 272 for the first server 510a and then may be transmitted to the AP apparatus 400, and vice versa.

FIG. 8 is a flowchart illustrating a method for operating a home appliance according to an embodiment of the present invention, and FIGS. 9 to 10c are views referred to for describing the operating method of FIG. 8.

Power is supplied to the home appliance 200 according to operation S803 of a power button (S705). Step S705 corresponds to step S805 of FIG. 9.

More specifically, a converter (not shown) for converting a commercial AC voltage into a DC voltage based on operation of the power button and the voltage is supplied to the controller 270, the driving unit 245, etc.

At this time, if input is not performed, power is supplied to each module of the home appliance 200 but each module may be in a standby mode.

In step S705, the network connection related indicator 610 and the smart grid related indicator 630 are in an off state.

Next, the home appliance 200 transmits network setup related information to an external device according to operation of a network setup button (S715) if network setup is not completed (S710). Then, the home appliance receives network related information from the AP apparatus (S720). Then, the home appliance accesses the AP apparatus based on the network related information (S725). Steps S710 to S725 correspond to steps S810 to S825 of FIG. 9, respectively.

If the user operates the network setup button of the home appliance upon initial operation of the home appliance, a network setup mode may be performed.

Alternatively, the network setup mode may be automatically performed when the home appliance is initially powered on or when network setup is not completed.

The network setup button 701 may be separately provided on the operation panel as shown in FIG. 10a or may be replaced with the network connection related indicator.

The controller 270 of the home appliance 200 may control performance of the network setup mode when the network connection related indicator 610 or the smart grid related indicator 630 is pressed in a state in which network setup is not completed.

For example, if the smart grid related indicator 630 is pressed for a first time (e.g., 5 seconds), the network setup mode may be performed.

For network setup, the communication unit 222 and, more particularly, the Wi-Fi application 274 of the communication unit 222 may transmit the network setup related information to the AP apparatus 400. More specifically, the communication unit 222 may transmit port information of the home appliance to the AP apparatus 400. The port information may be UDP port information or TCP port information, for example.

The communication unit 222 transmits a single data packet including a plurality of attribute data and values of the attribute data to the AP apparatus 400 or the server 500 when a predetermined event occurs.

More specifically, as described above, when a network setup event occurs, as shown in (a) of FIG. 10b, the home appliance 200 may transmit a data packet Pka including attribute data for port information and a value of the attribute data to the AP apparatus 400. In the figure, one data packet Pka includes a pair of attribute data and a value of the attribute data.

As another example, when a network setup event occurs, as shown in (a) of FIG. 10c, the home appliance 200 may transmit, to the AP apparatus 400, a data packet Pkc including a first pair pa1 including attribute data for port information and a value of the attribute data, a second pair pa2 including attribute data for a product id and a value of the attribute data, a third pair pa3 including attribute data for a device name and a value of the attribute data and a fourth pair pa4 including attribute data for a device password and a value of the attribute data as a single data packet. The data packet Pkc may further include a pair including attribute data for a domain name of a server and a value of the attribute data.

The AP apparatus 400 may receive network setup related information from the home appliance 200 and transmit network related information to the home appliance 200 in response thereto.

The home appliance 200 receives network related information. The network related information may include at least one of port information, TCP/IP information, MAC address information, network identifier information (service set identifier (SSID)), etc. of the AP apparatus 400.

The Wi-Fi application 274 of the home appliance 200 receives network related information and accesses the AP apparatus 400 using the received network related information under control of the controller 270.

The memory 240 stores the received network related information for future use.

If the smart grid related indicator 630 operates such that the home appliance enters the network setup mode, the smart grid related indicator 630 may be turned on with a first pattern, that is, blink, in step S715 among steps S710 to S720.

The network connection related indicator 610 is turned off during steps S710 to S720.

In step S725 in which the home appliance 200 accesses the AP apparatus 400, the network connection related indicator 610 may be turned on with the first pattern and the smart grid related indicator 630 may be turned on with the second pattern. The first pattern may mean blinking and the second pattern may mean that the indicator is constantly turned on.

Next, the home appliance 200 determines whether product registration with the server is completed (S730) and transmits the product related information to the server (S735) if product registration is not performed. Then, the home appliance receives a product registration completion message from the server (S740). Steps S730 to S740 correspond to steps S830 to S840 of FIG. 8, respectively.

The controller 270 of the home appliance 200 may attempt to perform product registration with the server through separate user input.

Alternatively, the controller 270 of the home appliance 200 may transmit product related information to the server after accessing the AP apparatus 400.

For example, the communication unit 222 may transmit the network setup related information before accessing the AP apparatus 400 and transmit the product related information after accessing the AP apparatus 400.

The network setup related information includes port information of the communication unit 222 and the product related information may include at least one of a product id, a device name and a device password.

The communication unit 222 may transmit a single packet per event. For example, when a server product registration event occurs, for product registration with the server, attribute data for a product id, a device name, a device password or a server domain name and a value of the attribute data may be grouped and transmitted.

The communication unit 222 may receive a product registration completion message from the server 500 when product registration with the server 500 is completed. The received product registration completion message is stored in the memory 240.

If product registration is attempted through user input in a state in which product registration is completed, the controller 270 may not perform product registration based on the product registration completion message stored in the memory 240.

If the network setup event occurs, as shown in (a) of FIG. 10b, the home appliance 200 may transmit a data packet Pka including attribute data for port information and a value of the attribute data to the AP apparatus 400. In the figure, one data packet Pka includes a pair of attribute data and a value of the attribute data.

When a server registration event occurs, as shown in FIG. 10(b), the home appliance 200 may transmit, to the AP apparatus 400, a data packet Pkb including a first pair pa1 including attribute data for port information and a value of the attribute data, a second pair pa2 including attribute data for a product id and a value of the attribute data, a third pair pa3 including attribute data for a device name and a value of the attribute data and a fourth pair pa4 including attribute data for a device password and a value of the attribute data as a single data packet. The data packet Pkb may be transmitted to the server 500 unlike (a) of FIG. 10b.

The data packet Pkb may further include a pair including attribute data for a domain name of a server and a value of the attribute data.

As another example, the communication unit 222 may transmit the network setup related information and the product related information before and after accessing the AP apparatus 400. The communication unit 222 may transmit address information of the server when the product related information is transmitted.

When a network setup event occurs, as shown in (a) of FIG. 10c, the home appliance 200 may transmit, to the AP apparatus 400, a data packet Pkc including a first pair pa1 including attribute data for port information and a value of the attribute data, a second pair pa2 including attribute data for a product id and a value of the attribute data, a third pair pa3 including attribute data for a device name and a value of the attribute data and a fourth pair pa4 including attribute data for a device password and a value of the attribute data as a single data packet. The data packet Pkc may further include a pair including attribute data for a domain name of a server and a value of the attribute data.

When a server registration event occurs, as shown in (b) of FIG. 10c, the home appliance 200 transmits the data packet Pkc. The data packet Pkc may be transmitted to the server 500 unlike (a) of FIG. 10c.

During steps S730 to S735, the network connection related indicator 610 is turned on with the first pattern and the smart grid related indicator 630 is turned on with the second pattern.

In step S740, since the home appliance 200 is connected to the server 400, the network connection related indicator 610 and the smart grid related indicator 630 may be turned on with the second pattern, that is, may be constantly turned on.

Next, the home appliance 200 determines whether wireless network disconnection continues for a predetermined period (S745) and re-accesses the AP apparatus based on the received information if wireless network disconnection does not continue (S750). Steps S745 to S750 correspond to steps S845 to S850 of FIG. 9, respectively.

The home appliance 200 attempts to re-access the AP apparatus 400 for a predetermined time (e.g., 2 minutes), if the home appliance is temporarily disconnected from the AP apparatus 400. The home appliance attempts to access the AP apparatus 400 based on the network related information of the AP apparatus 400 stored in the memory 240.

The home appliance 200 decides that the home appliance is disconnected from the AP apparatus, that is, remains in a non-connection state, if the home appliance is disconnected from the AP apparatus 400 for the predetermined time or more.

In step S745, the home appliance 200 may turn the network connection related indicator 610 and the smart grid related indicator 630 on with the first pattern (blinking) if the home appliance is temporarily disconnected from the AP apparatus 400 for the predetermined time.

Unlike the figure, in step S745, the smart grid related indicator 630 may be turned on. At this time, blinking of the network connection related indicator 610 in step S745 is preferably different from blinking in steps S725 to S735. That is, different first patterns may be used.

More specifically, a ratio of on timing to off timing of the network connection related indicator 610 in steps S725 to S735 may be 1:1 but a ratio of on timing to off timing in step S745 may not be 1:1. Accordingly, the user may identify temporary disconnection of the network.

Since the home appliance re-accesses the server in step S750, similarly to step S740, the network connection related indicator 610 and the smart grid related indicator 630 may be turned on with the second pattern, that is, may be constantly turned on.

When the wireless network is disconnected for a predetermined time or more, the network connection related indicator 610 and the smart grid related indicator 630 are turned off.

A state in which the communication unit 222 of the home appliance 200 does not receive the network related information from the AP apparatus 400 may be referred to as an un-provisioned state, a state in which the communication unit 222 of the home appliance 200 attempts to access the AP apparatus 400 is referred to as a provisioning state, a state in which the communication unit 222 of the home appliance 200 receives and stores the network related information regardless of connection with the AP apparatus 400 is a provisioned state, and a state in which the communication unit 222 of the home appliance 200 is connected/disconnected to/from the AP apparatus 400 is a referred to as a connected/disconnected state.

A state in which the communication unit 222 of the home appliance 200 is not registered with the server 500 is referred to as an un-registered state, a state in which the communication unit 222 of the home appliance 200 attempts to access the server 500 is referred to as a registering state, a state in which the communication unit 222 of the home appliance 200 is initially registered with the server 500 is referred to as a registered state, and a state in which the communication unit 222 of the home appliance 200 is connected/disconnected to/from the server 500 is referred to as a connected/disconnected state.

FIG. 11 is a flowchart illustrating a method for operating a home appliance according to another embodiment of the present invention, and FIGS. 12 to 13b are views referred to for describing the operating method of FIG. 11.

The communication unit 222 of the home appliance 200 periodically transmits a check signal to the accessed server (S905) and receives a response signal corresponding to the check signal from the server (S910). Steps S905 to S910 correspond to steps S1005 to S1010 of FIG. 12, respectively.

More specifically, the communication unit 222 of the home appliance 200 may transmit the check signal every minute.

The check signal may be a heartbeat signal and the response signal may be a response signal to the heartbeat signal.

The home appliance 200 may transmit a single data packet including attribute data for an appliance status and a control lock status and a value of the attribute data as a check signal and receive a response signal from the server 500.

FIG. 13a shows the case in which a check signal Sch is output from the home appliance 200 and is transmitted to the server 500 via the AP apparatus 400 and a response signal Sre is output from the server 500 and is input to the home appliance 200 via the AP apparatus 400.

Next, the home appliance 200 determines whether the response signal is not received for a first predetermined time and, if so, retransmits the check signal (S920). Steps S915 to S920 correspond to steps S1015 to S1020 of FIG. 12, respectively.

The controller 270 of the home appliance 200 retransmits the check signal when the response signal is not received for the first predetermined time. The first predetermined time may correspond to 2 minutes, for example. When the check signal is transmitted every 1 minute, the controller 270 of the home appliance 200 may retransmit the check signal when the response signal is not received twice.

The retransmitted check signal may be a heartbeat signal.

Alternatively, the retransmitted check signal may include a single data packet including attribute data for a home appliance status and a control lock status and a value of the attribute data.

FIG. 13b shows the case in which a retransmission check signal Sreq is output from the home appliance 200 and is transmitted to the server 500 via the AP apparatus 400 and a response signal Smsg is output from the server 500 and is input to the home appliance 200 via the AP apparatus 400.

After retransmission, the home appliance 200 determines whether the response signal is not received for a second predetermined time (S925) and, if so, determines that connection with the server is broken (S930). The home appliance 200 re-accesses the server based on the received information (S935). Steps S925 to S935 correspond to steps S1025 to S1035 of FIG. 12, respectively.

The controller 270 of the home appliance 200 determines that the home appliance is disconnected from the server 500 when the response signal is not received for the second predetermined time. The second predetermined time is preferably less than the first predetermined time. In order to check the connection state immediately after retransmission, the second predetermined time is preferably set to be short. For example, the second predetermined time may correspond to 1 minute. The controller 270 of the home appliance 200 determines that the home appliance is disconnected from the server 500, when the response signal is not received for 1 minute, that is, when the response signal is not received once.

When connection with the server 500 is broken but is connection with the AP apparatus 400 is maintained, as described above, the network connection related indicator 610 may blink and the smart grid related indicator 630 may be constantly turned on.

FIG. 14 is a flowchart illustrating a method for operating a home appliance according to another embodiment of the present invention, and FIGS. 15 to 16b are views referred to for describing the operating method of FIG. 14.

The home appliance 200 determines whether a first reset mode is set (S1105) and, if so, breaks the connection with the AP apparatus (S1110). Then, the network related information of the AP apparatus stored in the memory is deleted (S1115). Steps S1105 to S1115 correspond to steps S1205 to S1215 of FIG. 15, respectively.

For example, when the smart grid related indicator 630 is pressed for a time Ta (e.g., 5 seconds) in a state in which the home appliance 200 is connected to the AP apparatus 400 in step S725 or is connected to the server 500 in step S740, the home appliance 200 may be in a de-provisioned state as the first reset mode (local reset mode).

The controller 270 of the home appliance 200 controls the communication unit 222 to break the connection with the AP apparatus 400 in the first reset mode and controls deletion of the network related information received from the AP apparatus 400 and stored in the memory 240.

Thus, the communication unit 222 of the home appliance 200 may break the connection with the AP apparatus 400 in the first reset mode, as shown in FIG. 16a.

The network connection related indicator 610 and the smart grid related indicator 630 may both be turned off. The smart grid related indicator 630 may blink three times before being turned off.

Next, if the first reset mode is not set in step S1105, step S1120 may be performed.

That is, the home appliance 200 determines whether a second reset mode is set (S1120) and, if so, transmits a deletion request signal for product related information to the server (S1125). Then, the home appliance may receive a deletion completion message from the server (S1130). Steps S1120 to S1130 correspond to steps S1220 to S1230 of FIG. 15, respectively.

For example, if the smart grid related indicator 630 is pressed predetermined times (e.g., 5 times) for a time tb (e.g., 10 seconds) in a state in which the home appliance 200 is connected to the server 500 in step S740, the home appliance 200 may perform the second reset mode (factory reset mode).

In the second reset mode, the communication unit 222 of the home appliance 200 may transmit a deletion request signal Sreq_de to the server 500 and receive a deletion completion signal Smsg_de from the server 500, as shown in (a) of FIG. 16b.

Next, the home appliance 200 breaks the connection with the AP apparatus S1135. Then, the home appliance deletes the network related information of the AP apparatus stored in the memory (S1140). Steps S1135 to S1140 correspond to steps S1235 to S1240 of FIG. 15, respectively.

In the second reset mode, the controller 270 of the home appliance 200 controls the communication unit 222 to break the connection with the AP apparatus 400 and controls deletion of the network related information received from the AP apparatus 400 and stored in the memory 240, when the deletion completion message Smsg_de is received from the server 500.

The communication unit 222 of the home appliance 200 may break the connection with the AP apparatus 400 in the first reset mode, as shown in (b) of FIG. 16b.

FIG. 17 is a flowchart illustrating a method for operating a home appliance according to another embodiment of the present invention, and FIGS. 18a to 18d are views referred to for describing the operating method of FIG. 17.

The home appliance 200 determines whether a signal for entering the smart grid mode is received (S1710), determines whether the home appliance is connected to the AP apparatus 400 and the server 500 (S1715) if the signal is received, and turns the smart grid related indicator 630 and the network connection related indicator 610 on with the second pattern (S1720) if the home appliance is connected to the AP apparatus and the server.

When the home appliance 200 is powered on and connected to the AP apparatus 400 and the server 500, the smart grid related indicator 630 may be constantly turned on by default. That is, the home appliance may enter the smart grid mode. At this time, the network connection related indicator 610 may also be constantly turned on.

As shown in (a) of FIG. 18a, when the user presses the smart grid related indicator 630 in a state in which the smart grid related indicator 630 of the home appliance 200 is turned off, the smart grid related indicator 630 may be constantly turned on if the home appliance 200 is connected to the AP apparatus 400 and the server 500. The home appliance may enter the smart grid mode.

If the home appliance is not connected to the AP apparatus and the server in step S1715, the home appliance 200 determines whether the home appliance is connected to the AP apparatus but is not connected to the server (S1725), and, if so, turns the smart grid related indicator 630 on with the second pattern and turns the network connection related indicator 610 on with the first pattern (S1730). That is, in step S725, the network connection related indicator 610 may blink and the smart grid related indicator 630 may be constantly turned on.

As shown in (b) of FIG. 18(a), when the user presses the smart grid related indicator 630 in a state in which the smart grid related indicator of the home appliance 200 is turned off, the network connection related indicator 610 may blink and the smart grid related indicator 630 may be constantly turned on if the home appliance 200 is connected to the AP apparatus 400 but is not connected to the server 500.

Next, after step S1720 or after step S1730, any one of step S1740, step S1750 or step S1760 may be performed.

First, in step S1740, the home appliance 200 determines whether power information is received from the server 500 (S1740) and, if so, turns the grid mode indicator on (S1745).

When the communication unit 222 of the home appliance 200 receives power information such as a dr signal from the server 500 in the smart grid mode as shown in FIG. (a) of FIG. 18b, the grid mode indicator 620 may be temporarily turned on as shown in (b) of FIG. 18b.

The power information received by the home appliance 200 includes a single data packet Sdr, the data packet Sdr may include set DR mode data as attribute data, and a value of the attribute data may include a duration hour, a duration minute, an offset hour and an offset minute.

The home appliance 200 may pause at a time corresponding to a DR period (e.g., a peak time) based on the received power information and re-operate after the peak time. That is, the home appliance 200 may operate in the smart grid mode.

For example, according to the smart grid mode, the compressor of the refrigerator may be temporarily turned off and rotation of the tub of the washing machine may pause.

The power information signal received by the communication unit 222 from the server 510 may be divided into first power information and second power information. The first power information may correspond to a signal for saving power by 13% and the second power information may correspond to a signal for saving power by 50%.

Upon operation of the home appliance and, more particularly, the driving unit 245, the controller 270 of the home appliance 200 may control the driving unit 245 to continuously operate when the first power information signal is received from the communication unit 222 and control the driving unit 245 to pause and re-operate when the second power information signal is received from the communication unit 222. That is, when the second power information signal requiring more power consumption reduction is received, the driving unit may pause, thereby reducing power consumption.

The controller 270 of the home appliance 200 may control the home appliance to operate in a power saving mode based on the first power information signal when the first power information signal or the second power information signal is received from the communication unit 222, upon non-operation of the driving unit 245.

In step S1750, the home appliance 200 determines whether an override mode is set (S1750) and, if so, turns the smart grid related indicator on with the second pattern and turns the grid mode indicator off (S1755).

For example, as shown in FIG. 18c, when the override button 645 is pressed, the grid mode indicator 620 may be turned off and the smart grid related indicator 630 may be turned on with the second pattern.

As another example, as shown in FIG. 18d, when the override button 645 is pressed, the network connection related indicator 610 may blink and the smart grid related indicator 630 may be turned on. Then, the network connection related indicator 610 and the smart grid related indicator 630 may both be turned off.

The override button 645 may be a grid button included in the display 230. Accordingly, when the grid button (not shown) is pressed in a state in which the grid mode indicator is turned on and the smart grid indicator is turned on, the override mode may be performed.

The override mode means that the home appliance 200 continuously operates without pause even at the time corresponding to the DR time (e.g., the peak time) even when the power information is received from the server 500.

For example, the compressor of the refrigerator may continuously operate without pause or the tub of the washing machine may continuously rotate without pause even at the peak time, according to the override mode which has priority higher than that of the smart grid mode.

In step S1760, the home appliance 200 determines whether a signal for terminating a smart grid mode is received from the server 500 (S1760) and, if so, turns the smart grid related indicator off (S1765).

The controller 270 of the home appliance 200 breaks the connection with the AP apparatus 400, when a signal for breaking a connection is received.

At this time, the controller 270 of the home appliance 200 may transmit a data packet corresponding to a power off event to the server 500 before breaking the connection with the AP apparatus 400. The transmitted data packet is a single packet and may include a plurality of attribute data such as a home appliance status, a remote control status and a control lock status and a value of the attribute data.

FIGS. 19a to 19d are diagrams showing various data packets transmittable between the home appliance and the server.

According to the embodiment of the present invention, the communication unit 222 of the home appliance 200 transmits or receives a single packet per event.

FIG. 19a shows the case in which the home appliance 200 receives refresh request data from the server 500 and FIG. 19b shows the case in which the home appliance 200 transmits a refresh data packet as a single packet in response thereto.

In particular, if the home appliance 200 is a drier or a washing machine, a refresh data event occurs. Therefore, a plurality of attribute data and values of the attribute data may be transmitted to the server 500 as a single packet.

The plurality of attribute data may include model number, software version and hardware number and may further include at least one of cycle name, remote control status, control lock status, home appliance status, cycle state, estimated time remaining, error code, odometer, dry level setting, drying time setting, static shield status, wrinkle guard status, steam option status, temperature setting, current DR mode, device DR compliance and device DR reason code.

If the home appliance 200 is a refrigerator, a refresh data event occurs. Therefore, a plurality of attribute data and values of the attribute data may be transmitted to the server 500 as a single packet.

The plurality of attribute data may include model number, software version and hardware number and may further include at least one of freezer temperature setting, refrigerator temperature setting, ice maker status, speed chill status, control lock status, ambient temperature, door status, water pressure, water filter status, air filter status, error code, current DR mode, device DR compliance and device DR reason code.

FIG. 19b shows transmission of an error related data packet Serror to the server 500 when an error code occurs in the home appliance 200.

When the error code occurs, an error fault event occurs. Thus, the error related data packet Serror may include a plurality of attribute data such as a home appliance status, a remote control status, an error code and error details, and values of the attribute data.

FIG. 19c shows the case in which, when the power button 605 of the home appliance 200 is pressed, a power on event occurs and a related data packet Spower is transmitted to the server.

The related data packet Spower may include a plurality of attribute data such as a home appliance status, a remote control status and a control lock status, and values of the attribute data.

FIG. 19d shows the case in which, when the smart grid related indicator 630 in the off state is pressed, the communication unit 222 transmits a related data packet Ssgd to the server.

The related data packet Ssgd may include a plurality of attribute data such as a current DR mode and a current reason code, and values of the attribute data.

When a chime button is pressed for 5 seconds or a control lock on message is remotely received during a cycle in which the home appliance 200 operates, the control lock on event occurs. The attribute data such as the control lock status may be transmitted to the server.

When the chime button is pressed for 5 seconds one more, a control lock off event occurs. The attribute data such as the control lock status may be transmitted to the server.
