Title:
WASHING AND DRYING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/085266
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a washing and drying machine which can perform a drying operation in which a high-speed wind is output at the maximum current value without demagnetization, and insufficient drying or over-drying is inhibited. This washing and drying machine comprises: a rotary drum 3 in which laundry is accommodated; a blower fan which sends dry air into the rotary drum 3; a blowing fan motor 11 which drives the blower fan; a current detection unit which detects current flowing to the blowing fan motor 11; and a control device 100 which controls the blowing fan motor 11. When the current detected by the current detection unit is a predetermined threshold value or higher, the control device 100 causes the blowing fan motor 11 to rotate at a rotational speed that is fixed at the point in time at which the threshold value was exceeded.
