Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to an ozone generating unit.

(Prior Art) Most of the conventional ozone generators of this type generally have a pair of electrode plates with a discharge space in between, and forced air is blown between them, and many of them are relatively large.

(Problem to be solved) However, with the electrode plate described above, if the parallelism of the electrode plate over a large area is not accurate, or if there are irregularities in some parts, the discharge will occur only in one part, and only a part of the electrode plate will be discharged. The rate of corrosion and the need for two electrode plates is
It happens that the desired discharge cannot be obtained.

In addition, in order to increase the accuracy of electrode plate installation,
The processing accuracy must be high, and two electrode plates are required, resulting in an overall high cost.

Therefore, the purpose of this invention is to simplify the configuration, facilitate assembly, and reduce processing costs by using a single electrode plate and using a covered wire as the other electrode.

(Means for Solving the Problem) In order to achieve the above object, in this invention, an electrode plate made of a good electrical conductor is fixed to the wide inner wall surface of a flat discharge air chamber made of an insulating material.
This electrical terminal is provided on the outer surface of the discharge air chamber, the surface facing the electrode plate is covered with an insulating material, and an electric wire with one end extending outside the discharge air chamber is attached parallel to the electrode plate. The gap between these electrode plates and the wires is sufficient for corona discharge to occur and for air to pass through, and the wall plates of the discharge air chamber that sandwich these discharge areas are provided with air intake ports and discharge ports. The ozone generating unit is characterized in that the terminal and one end of the electric wire serve as a terminal for applying a high voltage between the electrode plate and the electric wire.

In order to achieve the above object, the ozone generating unit of this invention may be characterized in that the insulating coating material of the electric wire is made of silicone resin.

In order to achieve the above object, the ozone generating unit of this invention may be characterized in that the electric wire has at least one curved portion and is attached to the wall surface of the discharge air chamber.

(Function) A high-voltage power source is connected between a pair of terminals of the device constructed as described above, and the primary side of a blower is connected to the outlet of the discharge air chamber via a thin hose, and the device is operated. In this case, corona discharge occurs between the electric wire and the electrode plate, and oxygen (O ₂ ) in the surrounding air is released.
is converted to ozone (O ₃ ). At the same time, the air sucked in from the inlet of the discharge air chamber is sucked out by the blower together with the ozone sequentially converted in the discharge air chamber, and is discharged to the outside.

(Effects) In this device, which is configured and operates as described above, the structure of the discharge part is extremely simple, one side is a covered wire, so assembly is easy, and the whole is flat, so it is not bulky. Can be installed even in narrow spaces.

Also, when designing to change the amount of ozone generated, the outer size can be changed by bending the covered wire parallel to the electrode plate and changing the substantial length of the covered wire in the discharge area. can be done without changing.

(Example) This invention will now be described in detail based on a typical example.

Example 1 Reference numeral 10 denotes a discharge air chamber, which consists of a shallow flat rectangular body member 11 and a lid member 12 that exactly fits into the body member 11, both of which are made of an insulating material, and in this example, they are made of a synthetic resin injection molded product. The body member 11
An air intake port 14 is provided near one end of the portion that will become the bottom 13, and a thin pipe-shaped air discharge port 15 is provided near the other end, and in the illustration, the inner diameter is approximately 5 mm. be. Furthermore, in the embodiment, a filter 16 is attached to the air intake port 14 mentioned above.

Further, an electrode plate 17 is fixed to the inner surface of the bottom 13 located between the air intake port 14 and the air discharge port 15. A connecting screw terminal 18 electrically connected to a part of the electrode plate 17 is connected to the bottom 1.
body member 1 by penetrating body member 3 and protruding outside body member 11.
A tightening nut 19 is placed on the outside of the holder 1 and screwed into the tightening nut 19.

A clamping groove 21 for holding the covered wire 20 is provided along the inner surface of the lid member 12, facing the electrode plate 17, and in this embodiment, the clamping groove 2
1 has a bent portion 22 formed at one location. The number of bent portions 22 is determined in advance and formed according to the designed length of the covered electric wire 20. The covered wire 20 has a diameter of 1.0
A copper wire 24 having a diameter of 3.2 mm and coated with silicone resin was used. Therefore, the depth and width of the holding groove 21 are also set to these dimensions.

A spacer is provided on the inner surface of the lid member 12 or the body member 11 so that when the lid member 12 is fitted into the body member 11, the gap D between the electrode plate 17 and the covered wire 20 is 1.5 mm. A projection 23 is provided.

Body member 11 with electrode plate 17 as described above attached
The cover member 12 to which the covered electric wire 20 is attached is fitted, and when the spacer protrusion 23 comes into contact with the mating member, the two are fixed using an appropriate fixing means such as adhesive. In this way, a predetermined corona discharge gap D is formed between the electrode plate 17 and the covered wire 20, and at the same time, a space through which air can pass is formed.

In order to use the ozone generating unit formed in this way, the pipe-shaped air outlet 15
Connect a hose to the terminal, connect the primary side of the blower to the other end, apply 5000V and 0.15mA between the connecting screw terminal 18 and one end of the covered electric wire 20, and operate the blower.

In this embodiment, the hose connected to the motor can also be thin, and by simply inserting this hose into a space that requires ozone, the ozone mixture can be supplied to that space.

Embodiment 2 The mounting structure of the body member 11 and the electrode plate is completely the same as in the first embodiment. The difference lies in the shape of the clamping groove 21 of the lid member 12, in which support protrusions 25 with a height equivalent to the diameter are provided in parallel with an interval equivalent to the diameter of the covered electric wire 20, and these protrusions 25
do not reach the ends of the cover member 12, and a gap is provided between each support protrusion 25 and the side wall 26 of the body member 11 to allow the covered electric wire 20 to be laid. When fitting the covered wire 20 into the holding groove 21 formed between them, if it is fitted into the neighboring holding grooves 21 one after another as shown by the double chain line in FIG. By fitting the holding grooves 21 into the holding grooves 21 at appropriate intervals depending on the desired ozone output, the length of the covered wire 20 located in the discharge space can be shortened accordingly.

In other words, in this embodiment, in addition to the effects of this invention described above, even with a single ozone generation unit, by slightly changing the wiring position of the covered electric wire 20, it is possible to achieve several levels of ozone generation output. is obtained.
