AI Technical Summary
Technical Problem
Conventional liquid agent tanks in washing machines suffer from filter clogging due to exposure of the filter to air, leading to increased moisture evaporation and concentration, which causes the liquid agent to stick and clog the filter.
Method used
A liquid tank design with a discharge port, check valve, and a filter member positioned to be parallel to the liquid level, ensuring the filter remains submerged for longer, and a remaining amount detection system to prevent exposure to air.
Benefits of technology
The design extends the time before the filter is exposed to air, effectively preventing clogging and maintaining efficient liquid discharge.

Abstract
To provide a liquid tank and washing machine that can suppress filter clogging. [Solution] A liquid tank 20 used in a washing machine with an automatic liquid dispensing function includes a discharge port 22 that allows the liquid contained in the liquid tank 20 to be discharged to the outside, a check valve 211 that opens and closes the discharge port 22 in accordance with the attachment and detachment of the liquid tank 20 to the washing machine, and a filter member 212 located upstream of the check valve 211 and positioned at the bottom of the liquid tank 20. The filter member 212 has a filter F that is aligned with the direction in which the bottom surface of the bottom of the liquid tank 20 extends.
