Methods and apparatuses to relieve excessive suction within swimming pool skimmers

摘要

A pool skimmer including an upper skimmer housing, a lower skimmer housing, a channel, and a fluid path is disclosed. The upper skimmer housing includes a pool throat opening having an upper wall and a lower wall, a deck throat opening, and a skimmer rim. The channel extends from a channel lower end positioned between the skimmer rim and an outer wall of the upper skimmer housing to a channel upper end positioned at an elevation that is least halfway between the lower wall and the upper wall. The lower skimmer housing includes a pump inlet port, a pool return port, and one or more pump suction ports. The fluid path extends from the one or more suction ports to the channel to allow fluid communication between the one or more suction ports and the channel upper end when a basket is mounted to the skimmer rim.

1. A pool skimmer, comprising:
a skimmer housing comprising an upper skimmer housing and a lower skimmer housing, the upper skimmer housing comprising a pool throat opening having an upper wall and a lower wall, a deck throat opening, a basket opening, and a skimmer rim proximate the basket opening, and the lower skimmer housing comprising a skimmer bottom and one or more pump suction ports; a channel extending from a channel lower end positioned between the skimmer rim and an outer wall of the upper skimmer housing to a channel upper end positioned proximate the deck throat opening at an elevation that is least halfway between the lower wall and the upper wall of the upper skimmer housing, wherein the channel is formed between the outer wall of the upper skimmer housing and a channel inner wall coupled to the upper skimmer housing; and a fluid path extending from the one or more suction ports to the channel to allow fluid communication between the one or more suction ports and the channel upper end when a basket is mounted to the skimmer rim of the upper skimmer housing.
