Alternatively, a large number of holes 10a provided at appropriate intervals are opened, and water or water is obliquely applied from the slit or hole 10a toward the inner surface (back surface) of the lower belt portion 40a of the endless conveying belt 40. A fluid 11 such as compressed air is jetted.

Next, the operation of the conventional dehydrator having the above configuration will be described.
In the standby state before the start of the dehydration process, the endless conveyor belt 40 is stopped, the basket 42 is in the lowered position, and the piston rod 51 is in the raised position. In this state (the state in which there is no washing object 60 in FIG. 8). A substantially fixed amount of the washing object 60 is put into the empty basket 42 together with the treated water from the continuous water washer 58. The treated water passes through a small hole in the side wall of the basket 42 and a small gap in the endless conveying belt 40 and is collected in a water receiving tank 35 provided on the gantry 36. Next, the hydraulic device 48 is actuated in response to a charging completion signal from the continuous water washer 58, the piston rod 51 is lowered, the membrane 53 comes into contact with the upper surface of the washing object 60, and this is pressurized to press the washing object 60.

When the endless conveyor belt 40 stops, the basket 42 descends and returns to the initial standby state.

  In this conventional dehydrator, the object to be washed 60 is dehydrated under pressure by the membrane 53 when there is a lot of lint and dust (hereinafter referred to as lint 12 together) such as a mat or mop. The treated water contains a large amount of these lints 12 and is caught when passing through the small gap of the endless conveying belt 40 to clog the surface of the endless conveying belt 40, and the dehydrated treated water is endlessly conveyed for a long time. There is a problem that the remaining water rate of the object to be cleaned 60 is increased on the belt 40, and the drying energy of the dryer in the subsequent process is increased.

  To solve this problem, after starting the endless conveyor belt 40, an electromagnetic valve (not shown) is opened at an appropriate time to inject water or compressed air from the slit or hole 10a of the fluid ejection nozzle 10, thereby lower belt portion 40a. The lint 12 adhering to the lower surface of the belt becomes the lint 13 and is detached from the endless transport belt 40, and the endless transport belt 40 returned to the upper standby position is not clogged and prevents dehydration from being hindered.
