Washing machine and method for providing notification thereof

1. A washing machine comprising:

a communicator;

a display;

a sensor for detecting a water temperature of residual water of the washing machine; and

a processor,

wherein when the water temperature detected by the sensor is equal to or lower than a first temperature, the processor is configured to:

receive data regarding a temperature of an area where the washing machine is located from an application server via the communicator, and

transmit the received data regarding the temperature to a data server via the communicator so that the received data regarding the temperature is transmitted to a user terminal device by the data server, and

wherein when the water temperature detected by the sensor is equal to or lower than a second temperature that is lower than the first temperature, the processor is configured to:

control the display to display a notification regarding freezing of the washing machine, and

transmit the notification to the application server via the communicator so that the notification is transmitted to the user terminal device by the application server.

2. The washing machine according to claim 1 , wherein:

the data regarding the temperature is stored in the data server and forwarded to the user terminal device based on a request of the user terminal device, and

the notification is transmitted, from the application server, to the user terminal device based on a user account that is registered with the washing machine.

3. The washing machine according to claim 1 , wherein when the water temperature detected by the sensor is equal to or lower than the first temperature, the processor is configured to:

transmit, to the application server, a request for the data regarding the temperature at a predetermined time interval,

receive the data regarding the temperature measured in the area where the washing machine is located from the application server via the communicator in response to the request, and

transmit the received data regarding the temperature to the data server via the communicator.

4. The washing machine according to claim 3 , wherein the processor is further configured to transmit the request to the application server for the data regarding the temperature at the predetermined time interval, before a temperature equal to or higher than a third temperature, that is higher than the first temperature, is detected by the sensor.

5. The washing machine according to claim 1 , wherein, in a state where the communicator is deactivated, the processor is configured to:

activate the communicator when the water temperature is equal to or lower than the first temperature, and

receive the data regarding the temperature from the application server via the activated communicator.

6. The washing machine according to claim 5 , wherein the processor is further configured to deactivate the activated communicator when the water temperature is equal to or higher than a third temperature, wherein the third temperature is higher than the first temperature.

7. The washing machine according to claim 1 , wherein the processor is configured to:

transmit the notification to the application server a predetermined number of times during a predetermined time interval; and

display the notification on the display.

8. The washing machine according to claim 7 , wherein before reaching the predetermined number of times that the notification is transmitted, the processor is configured to:

stop providing the notification when the water temperature detected by the sensor is equal to or higher than a third temperature that is higher than the second temperature, or a user command, for executing an anti-freeze function of the washing machine, is received.

9. The washing machine according to claim 1 , wherein when the washing machine is registered with a plurality of user accounts, the notification is transmitted by the application server to the user terminal device that is associated with a user account that is accessed most frequently among the plurality of user accounts.

10. The washing machine according to claim 1 , wherein when the washing machine is registered with a plurality of user accounts, the notification is transmitted to each of a plurality of user terminal devices communicating with the application server based on each of the plurality of user accounts, and

wherein the notification is displayable on the user terminal device, among the plurality of user terminal devices, that detects an access point connected to the washing machine or is connected to the access point.
