Claim 16:
17. The method of claim 1, further comprising:
measuring whether the flow speed of the rainwater measured by the rain sensor is a first reference value or more and measuring whether the flow angle is less than a second reference value by the controller;
determining whether a discharge amount of the air blowing apparatus is a maximum amount by the controller when the flow speed of the rainwater is the first reference value or more and the flow angle of the rainwater is less than the second reference value;
determining whether the flow angle of the rainwater exceeds the second reference value by the controller when the discharge amount of the air blowing apparatus is the maximum amount;
determining whether a spray angle of the rainwater is a minimum angle by the controller when the discharge amount of the air blowing apparatus is the maximum amount and the flow angle of the rainwater is the second reference value or less; and
providing notification to a user by the controller when the spray angle of the rainwater is the minimum angle.
