Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rotary ozone generator, and particularly to a rotary ozone generator used in small refrigerators and the like.

(Prior art) As a conventional rotary ozone generator,
There is one disclosed in Japanese Patent No. 58-125606. That is, as shown in FIG.
A shaft 31 is rotated by 0, a Sirotsko fan 32 is fixed to one end of the shaft 31, and a rotor 34 housed in a cylindrical body 33 forming a fixed electrode is fixed to the other end of the shaft 31. The Sirotskov fan 32 is housed in a fan casing 35, and external air is sucked in through an air intake port 36.

The air sucked and compressed by the Shirotsuko fan 32 is supplied into the cylinder 33 through a pipe 37, and a power supply section 38 is provided on the circumferential surface of the cylinder 33. On the other hand, a plurality of rotating electrodes 39 are formed on the circumferential surface of the rotor 34, and discharge occurs between the rotating electrodes 39 and the fixed electrodes 33, generating ozone.

Both ends of the cylindrical body 33 are closed by end plates 40 and 41, and a power supply portion 42 is provided on the central outer surface of the end plate 40.
The power supply portion 42 is connected to a contact 44 via a spring 43, and the contact 44 is in contact with a conductive end plate 45 of the rotor 34. With this structure, when a high voltage is applied between the power supply parts 38 and 42, a discharge occurs between the fixed electrode and the rotating electrode, and the generated ozone is discharged from the discharge port 46 attached to the end plate 40. Ru.

(Problems to be Solved by the Invention) However, in the conventional ozone generator, the Shirotzko fan 32 and the rotor 34 are provided separately on both sides of the motor, which not only increases the number of parts but also makes the device The overall size was large and it was inconvenient to install it in a small refrigerator or the like.

In view of these points, the present invention aims to provide a rotary ozone generator that can be made compact as a whole and is optimal for being incorporated into a small refrigerator or the like.

(Means for Solving the Problems) Therefore, the present invention houses a rotor that serves as a rotating electrode that is rotated by a motor in a cylinder that serves as a fixed electrode, and connects one end of the rotor to the motor. death,
The other end side is connected to a power supply part by a contact member, and a fan is formed on the circumferential surface of either end of the rotor.

(Function) If a fan is formed integrally with the rotor on the peripheral surface of one end of the rotor that forms the rotating electrode, a device for supplying compressed air such as a Sirotskov fan can be installed on the opposite side of the motor separately from the rotor. This is no longer necessary, and external air is sucked in by a fan through an air intake port provided on the end plate of the cylinder, and ozone is exhausted from an exhaust port formed on the end plate on the opposite side.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, the ozone generator 1 of the present invention has a cylindrical body 2, and this cylindrical body 2 is connected to an outer casing 3.
, a conductive fixed electrode 4 housed in a cylindrical shape, and an insulator 5 covering the fixed electrode 4. The diameter of the right end of the cylinder 2 in the figure increases to form an enlarged part 2a, and the left end of the cylinder 2 and the ends of the right enlarged part 2a are closed with insulating end plates 6 and 7. ing. The peripheries of the end plates 6, 7 are fixed to the flange portions 8, 9 of the casing 3 of the cylinder body 2 by bolts b, bb...b.

A motor 9 is fixed to the end plate 7.
is a rotating shaft 10, a rotor 11, and a stator 12.
These members are housed in the casing 13. The rotating shaft 10 of the motor is rotatably supported by a bearing 14 provided at the center of the end plate 7,
The rotating shaft 10 is fixed to one end surface of a rotor 15 forming a rotating electrode.

A portion of the rotor 15 corresponding to the fixed electrode 4 is made of a conductor 15a, and a plurality of fans 16, 16, . These fans 16 are shaped to blow external air into the cylinder 2. Air intake ports 17, 17, .

A power supply part 18 is formed in the center of the opposite end plate 6, and this power supply part 18 includes a terminal 19 to which a high voltage is applied, and a contactor 21 made of carbon biased by a spring 20. This contactor 21 is in contact with the center of the end face of the rotor 15. On the other hand, a power feeding part 21 is also formed on the circumferential surface of the cylinder 2, and this power feeding part 21 consists of a terminal 22, a spring presser 23, a spring 24, and a contact 25, and this contact 25 comes into contact with the fixed electrode 4. ing.

The motor 9 does not need to be an electric motor and may be any other rotation imparting means. Furthermore, in FIG. 1, the left end surface of the rotor 15 is simply in contact with the contactor 21;
is supported on one side, but as shown in FIG. 2, a shaft 26 is also protruded from the opposite end of the rotor 15 from the motor, and this shaft is rotatably supported by a bearing 27 implanted in the end plate 6. The contactor 21 may be brought into contact with the end face of the contactor 26. By doing so, it becomes possible to support the rotor 15 without twisting.

In this way, when the motor 9 rotates and the rotor 15 rotates, external air is sucked through the air intake port 17 formed in the end plate 7, and the air is sent to the discharge space between the inner surface of the cylinder body 2 and the rotor 15. , both power supply parts 1
Application of high voltage between 8 and 21 causes discharge and generates ozone. The generated ozone is taken out from exhaust ports 28, 28, . . . , formed in the end plate 6.

(Effects) As explained above, in the present invention, since the fan is integrally formed on the peripheral surface of one end of the rotor, the entire device can be formed compactly, making it ideal for small electric products such as small refrigerators.
