1. A float drain and enclosure assembly comprising:
- a panel forming a portion of an enclosure, the panel defining a punch having radially extending lobes circumferentially separated by respective teeth, wherein one or more struts extend from between at least one of the lobes and at least one of the teeth to support a grating with a plurality of drainage holes;
a basket to collect liquid from the enclosure, the basket including a bottom wall and including a locking arrangement configured to engage the teeth to secure the basket in alignment with the punch;
a sealing structure that extends away from the bottom wall, the sealing structure including a sealing surface that surrounds an outlet of the basket; and
a float configured to;
in a sealing configuration, seat against the sealing surface to prevent fluid flow out of the outlet; and
rise off of the sealing surface, due to buoyancy forces from the liquid as the liquid collects in the basket, to allow the liquid to flow out of the outlet;
the basket having a plurality of ribs extending at least partly radially inwardly into an interior area of the basket to at least partly separate the float from an inner wall of the basket.

Abstract
A float drain for an enclosure can include a basket to collect liquid from the enclosure, a sealing structure surrounding an outlet of the basket, and a float configured to seat against the sealing surface to prevent fluid flow out of the outlet and to rise off of the sealing surface due to buoyancy forces as the liquid collects in the basket. The float drain can include other features, including: ribs or other protrusions extending into an interior are of the basket to space the float apart from an inner wall of the basket; an angled orientation of the sealing surface; and a trough, at least partly defined by the sealing structure, to collect debris.

11. A float drain and enclosure assembly comprising:
-
a panel forming a portion of an enclosure, the panel defining a punch having at least one lobe, and one or more integrally formed struts supporting a grating with a plurality of drainage holes; a basket to collect liquid from the enclosure, the basket including an inner wall and a bottom wall; a sealing structure that includes a sealing surface, the sealing surface surrounding an outlet of the basket; and a float configured to; seat against the sealing surface to prevent fluid flow out of the outlet; and rise under buoyancy forces from the liquid to allow the liquid to flow out of the outlet; the sealing structure including a projecting wall that extends away from the bottom wall of the basket to support the sealing surface; the projecting wall defining, in cooperation with the inner wall of the basket, a trough to collect debris carried by the liquid; and the basket including a locking arrangement that includes; at least one locking tab opposite the bottom wall; and a flange that extends around the basket to define at least one gap between the flange and the at least one locking tab; the at least one locking tab being configured to extend through the at least one lobe so that the at least one gap receives the panel of the enclosure to secure the float drain to the panel. - View Dependent Claims (12, 13, 14, 15, 16, 17)
