(54) Laundry apparatus


(57) A laundry apparatus according to the present invention is capable of stably regulating a laundry drying temperature without reduction in the service life of a valve which regulates the amount of steam to be supplied to heating unit . In the laundry apparatus, a first steam supply passage (24a) having a relatively great passage diameter and a second steam supply passage (24b) having a relatively small passage diameter are provided independently of each other. Thus, a relatively great amount of steam is supplied from the first steam supply passage (24a) to a drying heater (13) with a first valve (V27) being opened, and a relatively small amount of steam is supplied to the drying heater (13) with a second valve (V28) being opened. By selectively using the first valve (V27) and the second valve (V28), the opening/closing frequencies of these valves are reduced. This makes it possible to stably regulate the laundry drying temperature while preventing reduction in the service lives of these valves.
