Claim 0:
1. A bubble generation device configured to intermittently discharge bubbles from each of a plurality of bubble discharge ports, the bubble generation device comprising:
a gas storage chamber that stores a liquid therein and stores a gas supplied into the liquid above the liquid;
a turnaround path that communicates with an upper portion of the gas storage chamber, extends downward, turns back, and extends upward;
the plurality of bubble discharge ports that discharge the gas passing through the turnaround path as bubbles; and
a bubble discharge chamber that communicates with each of the plurality of bubble discharge ports, wherein
a plurality of sets of the gas storage chamber and the turnaround path are provided,
each of the plurality of the turnaround path includes a first communication port communicating with the gas storage chamber, a second communication port communicating with the bubble discharge chamber on a downstream side of a turn-around point of the turnaround path in a gas traveling direction, a lowering portion extending downward from the first communication port, a turnaround portion turning back upward from below, and a rising portion extending upward from the turnaround portion and reaching the second communication port, and communicate with the bubble discharge chamber common to the second communication ports,
each of the plurality of bubble discharge ports is opened upward and arranged in a straight line,
opening areas of the plurality of bubble discharge ports are the same as each other,
a shape of each of the lowering portion, the turnaround portion, the rising portion, and the bubble discharge chamber is a shape extending along an arrangement direction of the plurality of bubble discharge ports,
a shape of each of the first communication port and the second communication port is a shape extending along the arrangement direction and
a sum of the opening areas in the plurality of the bubble discharge ports is smaller than a sum of an opening area of the second communication port in each of the plurality of the turnaround portions.
