AI Technical Summary
Technical Problem
Non-porous drum washing machines face challenges in integrating a water inlet structure and air exchange structure, leading to instability in water pressure and flow, which affects the washing process.
Method used
A clothing treatment device with a drum design that separates the drum bottom into independent water inlet and air exchange channels, using end caps and sealing rings to manage water and air flow, ensuring balanced air pressure and stable water intake.
Benefits of technology
The solution effectively stabilizes water intake pressure and flow, preventing contamination and improving washing efficiency by integrating the water inlet and air exchange structures within the non-porous drum washing machine.

Abstract
A clothing treatment device, the clothing treatment device includes a drum (1), an outer end cap (2) is provided at the center of the drum bottom (11) of the drum (1), and an inner end cap (3) is provided at the center of the drum bottom (11) which is provided inside the outer end cap, the inner peripheral wall of the outer end cap (2), the outer peripheral wall of the inner end cap (3), and the drum bottom (11) form a chamber (4), and the chamber (4) is divided into a water inlet channel (41) and an air exchange channel (42) which are independent of each other. (41) The water inlet channel (41) introduces external water into the drum (1), and the air exchange channel (42) communicates the inside and outside of the drum (1). By dividing the chamber (4) formed by the inner peripheral wall of the outer end cap (2), the outer peripheral wall of the inner end cap (3), and the bottom of the drum (11) into the water inlet channel (41) and the air exchange channel (42), the air exchange channel (42) is set close to the water inlet channel (41), so that the air pressure at the water inlet channel (41) is consistent with the outside of the drum (1), so as to avoid the occurrence of the phenomenon that the pressure at the water inlet of the non-porous drum is too large or too small and affects the water inlet water flow.
