a steam injection assembly for receiving the steam generated from the steam tank and injecting the steam to the vehicle seat at a predetermined interval from the vehicle seat; an automated robot for guiding a movement of the steam injection assembly; a steam ironing assembly, coupled to a robot mounting unit provided in the automated robot with the steam injection assembly, for receiving the steam generated from the steam tank and ironing the vehicle seat; a steam supplying unit for supplying the steam to the steam injection assembly or the steam ironing assembly, one end thereof being connected to the steam tank; a water recovery unit detachably connected to the steam supplying unit, for recovering water generated in the steam supplying unit during a steam supplying process; a steam supply controlling unit for selectively supplying the steam via the water recovery unit to the steam injection assembly or the steam ironing assembly; and a recovery tank for storing water recovered from the water recovery unit. ## Claims ### Claim 1 A steam ironing system for a vehicle seat cover, comprising: a steam tank for heating water to generate steam; a steam injection assembly for receiving the steam generated from the steam tank and injecting the steam to the vehicle seat at a predetermined interval from the vehicle seat; an automated robot for guiding a movement of the steam injection assembly; a steam ironing assembly, coupled to a robot mounting unit provided in the automated robot with the steam injection assembly, for receiving the steam generated from the steam tank and ironing the vehicle seat; a steam supplying unit for supplying the steam to the steam injection assembly or the steam ironing assembly, one end thereof being connected to the steam tank; a water recovery unit detachably connected to the steam supplying unit, for recovering water generated in the steam supplying unit during a steam supplying process; a steam supply controlling unit for selectively supplying the steam via the water recovery unit to the steam injection assembly or the steam ironing assembly; and a recovery tank for storing water recovered from the water recovery unit, wherein the steam injection assembly, comprises: a casing provided with an inner space; a blowing unit provided in the casing; a connection pipe coupled to the casing while forming a hollow; a heater unit provided in the connection pipe; a steam discharge guiding unit, coupled to the connection pipe, for guiding a blowing direction of air discharged from the blowing unit; a baffle, provided between the connection pipe and the steam discharge guiding unit, for dispersing hot air heated by the heater unit which moves from the connection pipe to the steam discharge guiding unit; and a first steam supplying pipe, provided inside the steam discharge guiding unit, for discharging the steam supplied from the steam supplying unit. ### Claim 2 (depends on 1) The system of claim 1, wherein the first steam supplying pipe, provided inside the steam discharge guiding unit, is formed to make a spiral along a longitudinal direction of the steam discharge guiding unit, and wherein a plurality of air moving holes having predetermined intervals are formed in the heater unit, so that the air flowed into one end of the heater unit through the air moving hole is heated by the heater unit, and then discharged to another end of the heater unit. ### Claim 3 (depends on 1) The system of claim 1, wherein the steam discharged from the first steam supplying pipe is injected to the vehicle seat while being heated to a predetermined temperature or above by the hot air heated by the heater unit. ### Claim 4 (depends on 1) The system of claim 1, wherein the steam ironing assembly, comprises: an ironing unit which includes a plurality of steam injection holes, and a plurality of discharging pins provided to be in communication with the steam injection holes and has an inner passage; and at least one heating element, embedded in the ironing unit, for heating the water generated in the ironing unit for evaporation, wherein the ironing unit comprises an upper cover with at least one steam inlet in communication with a second steam supplying unit; and a lower ironing board coupled to the upper cover and formed with the discharging pin, wherein the upper cover and the lower ironing board are coupled to each other so that a steam circulation space in which the steam circulates is formed inside the ironing unit. ### Claim 5 (depends on 4) The system of claim 4, wherein the heating element is made of a ceramic heater and is insert-embedded in the lower ironing board. ### Claim 6 (depends on 4) The system of claim 4, wherein the steam ironing assembly, further comprises: a water recovery port, provided in the upper cover, for recovering water generated in the ironing unit; a water recovery connecting pipe, connected to the water recovery port, for guiding the water generated in the ironing unit to the recovery tank; and a water moving groove formed along an inner periphery of the lower ironing board, and configured to move the water generated in the ironing unit towards the water recovery port, wherein at least one inclination part is formed on the top of the discharging pin.
