Abstract

An ozone-generating apparatus includes: a plurality of discharge tubes each including: a first electrode having a tubular shape extending along a first axis; a second electrode extending along the first axis; and a dielectric extending along the first axis and disposed between the first electrode and the second electrode, the plurality of discharge tubes including a first discharge tube and a second discharge tube adjacent to the first discharge tube; and a connecting member electrically connecting the second electrode of the first discharge tube to the second electrode of the second discharge tube. The connecting member faces an end of the dielectric of the first discharge tube and an end of the dielectric of the second discharge tube.

Claims (17)

1 . An ozone-generating apparatus comprising:

a plurality of discharge tubes each including: a first electrode having a tubular shape extending along a first axis; a second electrode extending along the first axis; a dielectric extending along the first axis and disposed between the first electrode and the second electrode, the plurality of discharge tubes including a first discharge tube and a second discharge tube adjacent to the first discharge tube; and a power supply member electrically connecting the second electrode and extending along the first axis; and

a conductive plate-shaped member electrically connecting the second electrode of the first discharge tube to the second electrode of the second discharge tube, wherein

the dielectric has a tubular shape and is disposed such that a gap defining a discharge space is formed between the dielectric and an inner circumferential face of the first electrode and such that a gap defining a discharge space is formed between the dielectric and an outer circumferential face of the second electrode,

the conductive plate-shaped member has a plurality of holes into which the power supply members of the first discharge tube and the second discharge tube are respectively inserted and fixed; and

the conductive plate-shaped member is disposed at an axial end of the dielectric of the first discharge tube and an axial end of the dielectric of the second discharge tube to oppose an end surface of each dielectric along the first axis.

2 . The ozone-generating apparatus according to claim 1 , further comprising:

a plurality of the conductive plate-shaped members including a first conductive plate-shaped member and a second conductive plate-shaped member, wherein

the first conductive plate-shaped member electrically connects the second electrode of the first discharge tube to the second electrode of the second discharge tube, and

the second conductive plate-shaped member electrically connects the second electrode of the first discharge tube to the second electrode of a third discharge tube, which is included in the plurality of discharge tubes and adjacent to the first discharge tube.

3 . The ozone-generating apparatus according to claim 2 , wherein

the plurality of the conductive plate-shaped members includes N (N is an integer of one or more) second conductive plate-shaped members and (N+1) or more first conductive plate-shaped members.

4 . The ozone-generating apparatus according to claim 2 , wherein

the first discharge tube, the second discharge tube, and the third discharge tube each have a power supply member electrically connecting the second electrode to the conductive plate-shaped member, and

the first discharge tube, the second discharge tube, and the third discharge tube are disposed along a predetermined linear direction, and a first linear direction of a line connecting a contact point between the power supply member of the first discharge tube and the first conductive plate-shaped member to a contact point between the power supply member of the second discharge tube and the first conductive plate-shaped member, a second linear direction of a line connecting a contact point between the power supply member of the first discharge tube and the second conductive plate-shaped member to a contact point between the power supply member of the third discharge tube and the second conductive plate-shaped member are different from the predetermined linear direction.

5 . The ozone-generating apparatus according to claim 1 , wherein

the dielectric is movable along the first axis.
