摘要： Disclosed is a vacuum breaker having further enhanced reliability. The vacuum breaker comprises: a main body having a water inlet (26, 41), a water outlet (34, 48), a water passage (30, 44) for fluidically connecting the water inlet and the water outlet, and a first ambient-air intake port (36, 50) and a second ambient-air intake port (37, 49) for allowing the water passage to fluidically communicate with ambient air therethrough; a first valve element (28, 42); and a second valve element (32, 46) disposed downstream of the first valve element. The first valve element is designed to be movable between a first position allowing the water inlet to fluidically communicate with a zone of the water passage between the first and second valve elements, when water is permitted to pass through the water passage, and a second position allowing the first ambient-air intake port to fluidically communicate with the zone of the water passage between the first and second valve elements, when water is inhibited from passing through the water passage. The second valve element is designed to be movable between a first position allowing the zone of the water passage between the first and second valve elements to fluidically communicate with the water outlet, when water is permitted to pass through the water passage, and a second position allowing the second ambient-air intake port to fluidically communicate with the water outlet, when water is inhibited from passing through the water passage.

摘要： The present invention provides a novel water spray technique that extends a cleansing area in a two-dimensional manner without moving a nozzle. A nozzle head 170 has a water swirling chamber 171, which is located immediately below a nozzle opening 31 and connects with the nozzle opening 31 via a small-diametral connection pipe 163. The water swirling chamber 171 is formed as a hollow room having a tapered inner wall. A head flow path 34 is eccentrically connected to the water swirling chamber 171. Cleansing water flowed through the head flow path 34 into the water swirling chamber 171 swirls along the tapered inner wall of the water swirling chamber 171 as shown by the arrow SY and is sprayed from the nozzle opening 31 in a spiral (cone-shaped) form.
