The invention discloses a drying wardrobe for a ship. A wardrobe body is fixed on a ship body and is internally divided into a clothes hanging chamber and a cabin, a convection fan is installed at the top of the clothes hanging chamber, and a heater and an ozone generator are installed in an induced draft channel of the convection fan. A compressor, a frequency converter, an evaporator, an electronic expansion valve, a drain pipe, a circulating fan and a condenser are installed in the cabin, an air inlet door is installed on an opening on the outer side of the lower portion of the cabin, and an air outlet door is installed on an opening on the upper portion of the cabin. A controller collects signals of humid wind temperature, air suction pressure, air suction temperature, hot air temperature, the temperature of the clothes hanging chamber and humidity and the like to be used for controlling a circulating air door, the frequency converter, the air inlet door, the electronic expansion valve, the circulating fan, the air outlet door, the convection fan, the ozone generator and the heater to work. The drying wardrobe is low in clothes drying energy consumption, clothes are clean and do not deform, hot and humidity gas is not discharging into the cabin in the drying process, automatic preheating can be performed when the ship sails in a cold region, normal starting is guaranteed, forced heat removal can be performed when the ship sails in a hot region, and the drying wardrobe can work normally.
