Air shower apparatus

An air shower apparatus comprising:

• a first face portion and a second face portion disposed to face each other in a first direction and generating an air shower inside a first space between the first face portion and the second face portion;
• a plurality of first blowers provided in the first face portion, each of the first blowers comprising a first blow-out port from which air is blown out;
• a plurality of second blowers provided in the second face portion, each of the second blowers comprising a first suction port through which air is sucked, the first suction port being disposed to face the first blow-out port in each of the first blowers;
• wherein, in a first set comprising a first blower from the plurality of first blowers and a second blower from the plurality of second blowers,
• the first blower blows out a first spiral airflow from the first blow-out port in the first blower toward the first suction port in the second blower,
• the second blower sucks the first spiral airflow blown out by the first blower from the first suction port in the second blower, and
• the air shower apparatus generates the air shower inside the first space by a plurality of the first spiral airflows blown out from a plurality of the first blow-out ports in each of the first blowers;
• a third face portion and a fourth face portion disposed to face each other in a second direction intersecting the first direction, the air shower apparatus generating the air shower inside the first space between the third face portion and the fourth face portion;
• a plurality of fifth blowers provided in the third face portion, each of the fifth blowers comprising a third blow-out port from which air is blown out;
• a plurality of sixth blowers provided in the fourth face portion, each of the sixth blowers comprising a third suction port through which air is sucked, the third suction port being disposed to face the third blow-out port in each of the fifth blowers;
• a plurality of seventh blowers provided in the fourth face portion, each of the seventh blowers comprising a fourth blow-out port from which air is blown out;
• and
• a plurality of eighth blowers provided in the third face portion, each of the eighth blowers comprising a fourth suction port through which air is sucked, the fourth suction port being disposed to face the fourth blow-out port in each of the seventh blowers;
• wherein, in a third set comprising a fifth blower from the plurality of fifth blowers and a sixth blower from the plurality of sixth blowers,
• the fifth blower blows out a third spiral airflow from the third blow-out port in the fifth blower toward the third suction port in the sixth blower, and
• the sixth blower sucks the third spiral airflow blown out by the fifth blower from the third suction port in the sixth blower, and
• wherein, in a fourth set comprising a seventh blower from the plurality of seventh blowers and an eighth blower from the plurality of eighth blowers,
• the seventh blower blows out a fourth spiral airflow from the fourth blow-out port in the seventh blower toward the fourth suction port in the eighth blower, and
• the eighth blower sucks the fourth spiral airflow blown out by the seventh blower from the fourth suction port in the eighth blower, and
• the air shower apparatus generates the air shower inside the first space by a plurality of the third spiral airflows blown out from a plurality of the third blow-out ports in each of the fifth blowers and a plurality of the fourth spiral airflows blown out from a plurality of the fourth blow-out ports in each of the seventh blowers.
