Next, the operation of the cleaning apparatus 1 will be described.
When the switch (not shown) of the cleaning apparatus 1 is turned on, the air pump is activated, and the air flows through the air supply pipe 121 and the support box 101 and is supplied to the cleaning nozzle 5. Then, the air supplied to the cleaning nozzle 5 flows into the cylindrical tube 51 and the pipe 55 of the nozzle body 13 as shown by the arrows in FIG.
Further, the water pump is activated, and water flows into the water supply hose 123 and is supplied to the cleaning nozzle 5. Then, the water supplied to the cleaning nozzle 5 flows into the water supply pipe 27, the recess 73, and the water channel groove 79 as indicated by the arrow in FIG.

  The air ejected from the air ejection port 57 causes the rotating heads 115 of the cleaning nozzles 5a and 5b to rotate counterclockwise as indicated by the arrows in FIG. 6, and the rotating head 115 of the cleaning nozzles 5c and 5d rotates clockwise. Rotate in the direction of. That is, the cleaning heads 5a and 5c or the cleaning heads 5b and 5d adjacent to each other in the transport direction rotate in different directions.

  When the rotary head 115 rotates, the air injection ports 57 of the pair of pipes 55 move so as to draw a circular trajectory x, so that a spiral airflow is generated below the cleaning nozzle 5. And the water injected from the water injection port 95 is caught in this spiral airflow. Therefore, water is jetted in a spiral shape. Since the water injection port 95 is disposed in the region surrounded by the circular orbit x drawn by the air injection port 57 by the rotation of the rotary head 115, the water injected from the water injection port 95 is swirled. Is surely involved. Here, the area surrounded by the circular orbit x drawn by the air injection port 57 refers to a region including the circular orbit x drawn by the air injection port 57.

  The conveyor 131 is operated, and the container C placed on the mounting table 133 is conveyed rightward from the position indicated by the solid line in FIG. Since water is jetted into the lower region of the cleaning nozzle 5 in a spiral shape, when the container C passes through the lower side of the cleaning nozzle 5, as shown in FIG. The water collides with great momentum and intermittently. Therefore, dirt such as oil adhering to the container C can be reliably removed.

Further, as described above, since the rotary heads 115 of the cleaning nozzles 5a and 5c or the cleaning nozzles 5b and 5d adjacent to each other in the transport direction rotate in different directions, they are below the cleaning nozzles 5a and 5c or the cleaning nozzles 5b and 5d. Water is jetted to the side in a spiral shape that is reverse to each other. Therefore, water can be reliably applied to the bottom surface and the side surface of the container C from multiple directions.
In addition, since the cleaning nozzles 5a and 5c and a part of the cleaning nozzles 5b and 5d are arranged so as to overlap each other in the direction intersecting the transport direction of the container C, the cleaning nozzles 5a and 5c and the cleaning nozzles 5b and 5d It is possible to completely prevent the container C from being left unwashed at the boundary portion.

  Since water can collide with an object to be cleaned such as the container C from multiple directions, an impact can be given to dirt such as a rust preventive agent, cutting oil, and cutting waste adhering to the object to be cleaned. Thereby, even if the pressure of the water jetted from the water jet port 95 is not so high, the dirt adhered to the object to be cleaned can be sufficiently removed. Therefore, there is no need to provide an expensive high water pressure pump.

  Next, the water pump is stopped and the water jetted from the water jet 95 is stopped. The air pump remains in the operating state. And the container C mounted on the mounting base 133 is conveyed leftward from the position shown with a virtual line in FIG. 1, and the container C is dried. As described above, since a spiral airflow is generated below the cleaning nozzle 5, when the container C passes below the cleaning nozzle 5, as shown in FIG. Air hits from the direction. Therefore, the water adhering to the container C can be reliably removed by washing.

Since the air jetted from the air jet port 57 is compressed in the cleaning nozzle 5 and the like and becomes high temperature, the water conveyed by the air warms. Therefore, there is no need to provide a heater for heating water.
In addition, since the air sprayed from the air ejection port 57 is used for both cleaning the object to be cleaned and drying the object to be cleaned, it is not necessary to provide a separate drying device.
As described above, since the cleaning device 1 does not need to be provided with a drying device, a high water pressure pump, and a heater, the cost can be kept low.
