Home appliance connection method and home appliance connection device
A home appliance connection method according to embodiments of the present invention may comprise the steps of: setting a wireless mode to a station mode; periodically searching for a wireless network on the basis of the station mode; and, when a wireless network search request is received from a terminal device, transmitting found wireless network information to the terminal device. A home appliance connection method according to embodiments of the present invention may further comprise a step in which the terminal device receives found wireless network information, wherein the found wireless network information of the terminal device may be information from which a wireless network not associated with a home appliance for the terminal device has been filtered. A home appliance connection method according to embodiments of the present invention may further comprise a step of, when the wireless mode is a station mode, periodically changing the wireless mode into an access point (AP) mode and periodically transmitting a beacon message to the terminal device on the basis of the AP mode. A home appliance connection method according to embodiments of the present invention may comprise a step of receiving a first advertising message on the basis of a Bluetooth from the terminal device, wherein the first advertising message may comprise a home appliance registration request. Furthermore, a home appliance connection method may comprise the steps of: transmitting a second advertising message to the terminal device on the basis of the Bluetooth in response to the first advertising message; and searching for a wireless network in response to the first advertising message.

when the home appliance has not been registered, setting the wireless mode to a concurrent mode or an access point (AP) mode, and waiting to receive the wireless network searching request from the terminal device;
upon receiving the wireless network searching request from the terminal device, connecting the home appliance to the terminal device and a wireless network based on wireless network information received from the terminal device; and
deactivating the AP mode as the wireless mode.
5. The home appliance connection method of claim 2 , wherein the periodically transmitting the beacon message further includes changing a period value at which the beacon message is transmitted.
6. The home appliance connection method of claim 1 , wherein the method further comprises:
receiving, from the terminal device, a probe request message for wireless network search based on an active scanning scheme;
in response to the receipt of the probe request message, transmitting a probe response message to the terminal device; and
connecting the terminal device and the home appliance associated with the terminal device with each other, based on the probe request message and the probe response message.
7. A home appliance connection device comprising:
a controller configured to periodically search for a wireless network, when a wireless mode of the controller is a station mode;
a receiver configured to receive a wireless network searching request from a terminal device; and
a transmitter configured to transmit information about a searched wireless network to the terminal device,
wherein the receiver is further configured to receive information about a wireless network searched by the terminal device,
wherein in the information about the wireless network searched by the terminal device, a wireless network not associated with a home appliance associated with the terminal device is excluded in a filtered manner.
8. The home appliance connection device of claim 7 , wherein when the wireless mode of the controller is the station mode, the transmitter is further configured to periodically change the wireless mode to an access point (AP) mode, and then periodically transmit a beacon message to the terminal device under the AP mode.
9. The home appliance connection device of claim 7 , wherein the receiver is further configured to receive a first advertising message from the terminal device via Bluetooth communication, wherein the first advertising message includes a registration request of the home appliance,
wherein the transmitter is further configured to transmit a second advertising message to the terminal device via Bluetooth communication, in response to the receipt of the first advertising message, and
wherein the controller is further configured to search for a wireless network in response to the reception of the first advertising message.
10. The home appliance connection device of claim 7 , wherein the controller is further configured to:
power on the home appliance associated with the terminal device;
identify whether the home appliance has been registered;
when the home appliance has been registered, connect the home appliance to a wireless network corresponding to wireless network information about the registered home appliance;
when the home appliance has not been registered, set the wireless mode to a concurrent mode or an access point (AP) mode, wherein the receiver waits to receive the wireless network searching request from the terminal device;
when the receiver has received the wireless network searching request from the terminal device, connect the home appliance to the terminal device and a wireless network based on wireless network information received from the terminal device; and
deactivate the AP mode as the wireless mode.
11. The home appliance connection device of claim 8 , wherein the controller is further configured to change a period value at which the beacon message is transmitted.
