Title:

AUTOMATIC LIQUID DISCHARGE DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/231219

Kind Code:

A1

Abstract:

The present invention relates to an automatic liquid discharge device which has been improved to be able to operate well even when a float weight thereof is reduced. The automatic liquid discharge device comprises: a drain body (100) including a water collection chamber (120) having an inverted conical inclined inner circumferential surface (122) and disposed under a liquid inlet port (111), and having a drainage hole (130) formed at the center of the lower portion thereof; and a float (200) having an inverted conical inclined portion (221) which is guided to move along the inverted conical inclined inner circumferential surface (122) of the water collection chamber (120), and has a plurality of downwardly inclined ribs (230) protruding therefrom. The float (200) has an external communication air chamber (210) formed therein to be in communication with at least one pressure-balancing ventilation hole (211) provided on the upper side of the float, and thus, even when a high internal pressure is generated inside the water collection chamber (120), air comes in and out of the external communication air chamber (210) so as to prevent the float (200) from being crushed and thus enable the float (200) to normally function.
