Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device having a structure in which a cleaning liquid is circulated and used.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show an example of a cleaning device for circulating and using a cleaning liquid. In these drawings, the cleaning tank 60 includes a cleaning chamber 62 partitioned by a weir 61 and a cleaning liquid recovery chamber 63. The cleaning liquid recovery chamber 63 is the cleaning chamber 6
The cleaning liquid flowing from 2 due to overflow is received and fed back to the cleaning chamber 62.
In order to perform this feedback, the cleaning chamber 62 and the cleaning liquid recovery chamber 63 are connected by the circulation pipe 65. The circulation pipe 65 has a filter 6 for filtering and regenerating the cleaning liquid.
7 and a pump 66 that gives a circulating flow to the cleaning liquid. In this case, the circulation pipe 65 of FIG. 6 is connected to the bottom of the cleaning chamber 62, and the circulation pipe 65 of FIG. 7 is inserted into the cleaning chamber 62 from the upper part, but the same applies in that the cleaning liquid is supplied to the cleaning chamber 62. It has become a structure.

FIGS. 4 and 5 show a cleaning device described in Japanese Utility Model Laid-Open No. 2-91689 in order to improve these cleaning devices. The same members as those in FIGS. 6 and 7 are designated by the same reference numerals. It corresponds. Cleaning room 6 in this cleaning device
An adapter 70 is arranged at the bottom of 2. The adapter 70 is connected to the circulation pipe 65, the opening thereof faces the side opposite to the weir 61, and the cleaning liquid is ejected along the bottom of the cleaning chamber 62 by driving the pump 66. Reference numeral 71 is a guide provided at the bottom of the cleaning chamber 62 so as to face the opening of the adapter 70, and the cleaning liquid ejected from the adapter 70 is diverted to above the cleaning chamber 62. In the cleaning device of this structure, when the cleaning liquid is ejected from the adapter 70, the cleaning liquid flows as a laminar flow in the cleaning chamber 62 and overflows into the cleaning liquid recovery chamber 63, so that a large amount of cleaning liquid can overflow. Thus, the cleaning liquid can be efficiently regenerated.

[0004]

All of the conventional cleaning devices shown in FIGS. 4 to 7 described above have a problem that the suspended matter floating in the cleaning chamber cannot be efficiently discharged. That is, the cleaning liquid discharged from the circulation pipe 65 or the adapter 70 collides with an object to be cleaned introduced into the cleaning chamber 62 and becomes a turbulent flow, or a connection joint or a transfer provided on the inner wall of the cleaning chamber 62. This is because it collides with an arm or the like and becomes a turbulent flow, which disturbs the liquid flow of the entire cleaning liquid and does not flow along the inner wall of the cleaning chamber. In such a state where the suspended solids are stagnant in the cleaning chamber, the suspended solids cannot be discharged to the cleaning liquid recovery chamber, the regeneration efficiency of the cleaning liquid decreases, and the cleaning power of the cleaning liquid deteriorates. Further, when the object to be cleaned is pulled up from the cleaning chamber, the suspended matter is likely to reattach to the object to be cleaned, and the object to be cleaned cannot be cleaned cleanly.

The present invention has been made in consideration of the above problems, and an object thereof is to provide a cleaning device having a structure capable of promptly removing floating substances floating in a cleaning chamber and staying therein. .
