Tank having outlet positioned in protruding chamber below liquid storage chamber, and liquid-consuming device including the same

A tank comprising:

• a storage chamber for storing liquid therein;
• a bottom wall;
• a top wall opposing the bottom wall in an up-down direction and defining a top of the storage chamber, the top wall having a through-hole;
• and
• an outflow tube positioned in the storage chamber and extending in the up-down direction to have an outlet at a bottom thereof, the outflow tube defining therein an outflow channel in communication with the storage chamber through the outlet, the outflow channel being in communication with an outside of the tank through the through-hole to allow the liquid in the storage chamber to flow to the outside of the tank through the outlet and the through-hole,
• wherein the bottom wall has an inner surface including:
• a flat part extending in a lateral direction crossing the up-down direction and defining a bottom of the storage chamber;
• and
• a protruding part extending downward from the flat part and defining an extra space in communication with the storage chamber, the outlet being positioned in the extra space.

A tank comprising:

• a storage chamber for storing liquid therein;
• a top wall defining a top of the storage chamber in an up-down direction;
• a bottom wall positioned below the top wall and defining a bottom of the storage chamber in the up-down direction;
• a peripheral wall defining an end of the storage chamber in a lateral direction crossing the up-down direction;
• and
• an injection opening penetrating the top wall to allow liquid to be introduced into the storage chamber,
• wherein the top wall and the peripheral wall are integrally molded to constitute an integrally-molded wall structure, the bottom wall being liquid-tightly connected to the integrally-molded wall structure to define the storage chamber.
