Title:
TANK DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/193914
Kind Code:
A1
Abstract:
The present invention is capable of preventing bubbles from forming on a liquid surface even when the height of the liquid surface changes and the liquid surface shakes significantly. The interior of a tank body for storing a liquid is provided with a return filter provided so as to project downward from the top surface of the tank body, and a substantially plate-shaped float which is inserted into the interior of the tank body and which floats as the surface of the liquid stored in the tank body changes. The float has an opening formed therein which is larger than the diameter of a filter case, and when seen from a planar view, the float is positioned between the tank body and the filter case.
