Patent ID: 7698768

Claim:
A method for controlling a drum type washing machine with a laundry drying function, provided with a ventilating fan, the method comprising: inputting an operation command after selecting a user's desired washing course; carrying out a washing stroke and a rinsing stroke corresponding to the selected washing course if the operation command is input, and determining whether a dehydrating stroke starts; and driving the ventilating fan during the dehydrating stroke in accordance with a previously set driving pattern if it is sensed that the dehydrating stroke starts, wherein driving the ventilating fan includes successively driving the ventilating fan during a set dehydrating stroke period, or periodically driving the ventilating fan during a set dehydrating stroke period, wherein successively driving the ventilating fan includes: successively driving the ventilating fan during a whole dehydrating stroke period if the set period corresponds to the whole dehydrating stroke period; successively driving the ventilating fan during an intermittent dehydrating stroke period if the set period corresponds to the intermittent dehydrating stroke period; and successively driving the ventilating fan during an original dehydrating stroke period if the set period corresponds to the original dehydrating stroke period, and wherein periodically driving the ventilating fan includes: driving the ventilating fan at previously set intervals during a whole dehydrating stroke period if the set period corresponds to the whole dehydrating stroke period; driving the ventilating fan at the previously set intervals during an intermittent dehydrating stroke period if the set period corresponds to the intermittent dehydrating stroke period; and driving the ventilating fan at the previously set intervals during an original dehydrating stroke period if the set period corresponds to the original dehydrating stroke period.
