摘要： Disclosed is a reinforced towel dryer, comprising hanger and main machine comprising casing, heater, and fan. Bottom of the casing is provided with air outlet and inlet, the heater is located in air flow path of fan. The hanger comprises hanging rod and two supports having supporting section and vertical section abutting against wall. Vertical section is connected to rear end of supporting section. End of the hanging rod is supported on corresponding supporting section, upper end of vertical section is fixedly connected to rear side of casing. When casing is installed on wall, vertical section abuts against wall, then when fabrics are on the hanger, wall acts as rear fulcrum and bears heavy weight, weight on casing can be reduced to support hanger. There is no need for metal plate in casing, so structure of the casing is simplified, weight of the casing and the cost are reduced.
