TANK FOR PRESERVING A CHEMICAL SOLUTION AND APPARATUS FOR SUPPLYING A CHEMICAL SOLUTION

摘要

PURPOSE: A chemical storing tank and a chemical supply device including the same are provided to maintain a constant level of chemical by forming a space saving unit with a constant volume on the bottom of the chemical storing tank. CONSTITUTION: A bottom unit(110) has an outlet(112) for discharging the chemical. A sidewall(120) provides a space for storing the chemical. A space saving unit(140) is formed on the bottom unit to have a constant volume around the outlet and reduces a space filled with the chemical. The space saving unit is inclined from the sidewall to the outlet.
