Generally, the engine cylinder head is located above the cylinder block and forms a combustion chamber together with the cylinder, and a valve mechanism for opening and closing the intake and exhaust passageways is coupled. A water jacket or the like is a passage through which the cooling water can circulate. Accordingly, the engine cylinder head has a problem that a metal chip, cutting oil, or the like which is generated during machining due to a plurality of holes and a surface having a relatively complicated shape is adhered to the surface or inside thereof and is difficult to completely remove.

In order to solve this problem, Korean Patent Registration No. 10-1194122 discloses a cylinder head which is installed in the middle of a production line of an automobile engine cylinder head to remove a foreign substance on the surface of a transfer pallet and a cylinder head, A simple washing machine comprising: a first lift turn device on which a cylinder head and a transfer pallet are transferred from a production line; a pallet air blow device operated by a pallet air blow device cylinder; and a pallet cooler operated by a pallet coolant injector cylinder A first air room door for fixing the cylinder head transferred by the robot apparatus; a first air chamber door cylinder for tilting the first air chamber door; 1 < / RTI > air blower, A second air room door for fixing the cylinder head carried by the robot apparatus, a second air room door cylinder for tilting the second air room door and a second air room comprising a second air blowing device and a pallet air blowing device And a second lift turn device in which the transfer pallet having been cleaned by the pallet coolant injection device, the first air room, and the cylinder head having been cleaned in the second air room are moved together by the robot device A robot arm type automobile engine cylinder head and a conveyance pallet simple washer are known.

However, since only the repeated air blowing operation is performed in the first air chamber and the second air chamber, it is also difficult to completely remove foreign materials such as chips and cutting oil which are adhered to the inside of the engine cylinder head.
