Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ionic air purifier used in automobiles, general homes, companies, etc.

Conventional configurations and their problems Conventional ionic air purifiers have had problems in that they generate a lot of ozone and have a strong ozone odor. Activated carbon is generally used as a method to eliminate ozone odor, but since activated carbon filters remove ozone through contact adsorption, the air holes in the activated carbon must be made very small or the thickness must be increased to ensure that the contact area is・
Methods such as increasing residence time have been used. All of these methods increase ventilation resistance, and in the case of an air purifier using an ion blast system, the amount of air blown is particularly reduced, making it unusable.

Purpose of the Invention The present invention eliminates the above-mentioned conventional drawbacks and aims to reduce ozone by reduction.

Structure of the Invention The ionizing air purifier of the present invention includes an ionizing electrode and a counter electrode arranged in a ventilation path connecting an intake port and an exhaust port, generates a discharge between the two electrodes to induce an ionized wind, and A reducing gas vaporization port is provided in the ventilation passage, and the vaporization port is opened and closed in response to the discharge operation state. That is, since the vaporization port is opened only during discharge operation and closed at other times, reducing gas can be used efficiently without wasting it.

DESCRIPTION OF THE EMBODIMENTS The present invention will be described below with reference to the drawings. In FIG. 1, 1 is a box body, and 2 is an intake port through which dust-containing air is taken in. 3 is an exhaust port from which purified air is exhausted. Reference numeral 4 denotes a ventilation passage formed between the suction port 2 and the exhaust port 3.
Reference numeral 5 denotes an ionizing electrode which generates a silent discharge between it and a counter electrode 6 to induce an ionized wind, thereby causing air to flow from the intake port 2 to the exhaust port 3 in the ventilation path 4 . Reference numeral 7 denotes an accelerating electrode, which is arranged so that a high-voltage electric field is applied to the counter electrode 6 to ensure that cations accompanied by dust generated at the ionization electrode reach the counter electrode 6, thereby increasing dust collection efficiency. ing. Reference numeral 8 denotes a reducing gas vaporization port provided in the ventilation passage 4, through which reducing gas 9 is diffused into the ventilation passage 4. Reference numeral 10 denotes a reducing gas generating container, which is placed near the box 1 and contains a gas liquid 11.

A switch lever 12 is rotatable about a shaft 16, and has a switch contact 14 and a vent hole 13 for opening and closing the vaporizing port 8. 15 is a terminal connected to the contact 14;

In the above configuration, when a high voltage electric field is applied between the ionizing electrode 5 and the counter electrode 6, the ionizing electrode 5
A local dielectric breakdown occurs in the air around the ionizing electrode, resulting in an ionized state, and molecules with a different polarity from the ionizing electrode are absorbed by the ionizing electrode, and molecules with the same polarity flow toward the counter electrode 6. At this time, the flowing positive ions push the air molecules and generate a wind, which becomes an ion wind. Ozone is also created in this local dielectric breakdown state, but
A vaporizing port 8 for the reducing gas 9 is provided facing the ventilation path 4, and the contact 14 and the terminal 15 are connected in conjunction with the switch lever, and the venting port 13 is aligned with the vaporizing port 8 to release the reducing gas. 9 enters the ventilation passage, reacts with ozone, reduces the ozone, and removes the ozone. When the switch lever 12 is rotated to the state shown in FIG. 3, the switch is turned off and the vaporization port 8 is closed by the switch lever 12, so that the reducing gas is no longer vaporized, and wasteful volatilization of the gas liquid can be prevented.

Note that reducing gases include turpentine fragrances and hydrogen having sensitive groups.

Effects of the Invention As described above, the present invention disposes an ionizing electrode and a counter electrode in a ventilation path connecting an intake port and an exhaust port, generates a discharge between the two electrodes to induce an ion wind, and A reducing gas vaporization port is provided in a part of the unit, and this vaporization port opens and closes in conjunction with the discharge operation status, so that the reducing gas can remove ozone generated along with the ion wind during operation, and also when the operation is stopped. At the same time, the vaporization port is closed to stop subsequent gas emission, allowing efficient use of gas without waste.
