Abstract

PURPOSE:To enable the reduction of ozone by efficiently reducing ozone generated in inducing an ion wind with reductive gas, by providing a heat generator in the vicinity of a reductive gas generator to adjust liquefied gas to a constant temp. and volatilizing a definite amount of reductive gas. CONSTITUTION:An ionizing electrode 5 and an opposed electrode 6 are arranged in an air passing line 4 connecting a suction port 2 and an exhaust port 3 and discharge is generated between both electrodes to induce an ion wind while an vaporizing port 8 of reductive gas (e.g., hydrogen) is provided to a part of the air passing line 4 and a heat generator 12 for generating heat simultaneously with the generation of discharge is further arranged in the vicinity of a reductive gas generating container 10. That is, liquified gas is adjusted to a constant temp. regardless of a season and a definite amount of reductive gas is volatilized to efficiently reduce ozone generated in inducing an ionic wind with the reductive gas to enable the reduction of ozone and the necessary amount of the reductive gas can be made constant without making said gas wasteful. In addition, because the temp. of the liquified gas is low when operation is not performed and the flow of air is small, the volatile amount of the reductive gas becomes small.

Description

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

Conventional configurations and their problems Conventional ionic air purifiers have had the problem of generating a lot of ozone and having 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 vent holes in the activated carbon must be made very small or the thickness must be increased to reduce the contact area and band retention. Methods such as increasing the time have been used.

Both of these methods increase ventilation resistance,
Especially in the case of an ion-driven air purifier, the amount of air blown decreases, making it unusable.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and aims to reduce ozone by reducing the reducing gas, and in addition, stabilizes the above-mentioned reducing action.

Structure of the Invention The ionizing air purifier of the present invention has an ionizing electrode and a counter electrode disposed in a ventilation path connecting an intake port and an exhaust port, and generates an electric discharge between the two electrodes to induce an ionized wind. , a reducing gas vaporization port is provided in a part of the ventilation path, and a heating element is provided near the reducing gas generating container. Therefore, the ozone produced by the discharge phenomenon is reduced by a reducing gas. : The above gas is stably generated by the heating element. Furthermore, gas generation can be performed when necessary by controlling the heating element.

Description of examples Embodiments will be described below with reference to the accompanying drawings.

In the figure, 1 is a box body, and 2 is an intake port of the box body, through which dust-containing air is sucked. 3 is an exhaust port from which purified air is exhausted. Reference numeral 4 denotes a ventilation path 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 ionic wind, thereby causing air to flow from the intake port 2 to the exhaust port 3 in the ventilation passage 4 . 7 is an accelerating electrode, and counter electrode 6
The arrangement is such that a high voltage electric field is applied to the ionization electrode so that the cations accompanied by the dust generated at the ionization electrode reliably reach the counter electrode 6, thereby increasing the dust collection efficiency. Reference numeral 8 denotes a vaporization port provided in the ventilation path 4, which is provided so that the reducing gas 9 is diffused into the ventilation path 4. Reference numeral 1o denotes a reducing gas generating container, which contains a gas liquid 11 and is installed near the box body 1. 12
is a heating element, which is integrally provided on the lower surface of the reducing gas container 1o.

In the above configuration, when a high-voltage electric field is applied between the ionizing electrode 6 and the counter electrode 6, dielectric breakdown of the air occurs and the air becomes ionized, and molecules having a different polarity from the ionizing electrode 5 are absorbed by the ionizing electrode, and the same molecules are absorbed by the ionizing electrode. The molecules of the pole flow towards 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 produced in this dielectric breakdown state, but since the reducing gas is provided in a part of the ventilation passage 4 or facing the ventilation passage 4, ozone reacts with the reducing gas and reduces the amount generated. It is something that can be done. The reducing gas may be any reducing agent that reacts with ozone, such as hydrogen or a terpene fragrance having a sensitive group. Hydrogen reacts with ozone to become water, and the reducing property of having a CHO group removes 0 molecules of ozone and creates stable C0OH.
It also reacts with a terpene fragrance that has a double bond to form a single bond.

The heating element 12 warms the reducing gas container 10 and heats the reducing gas liquid 11 to a constant temperature regardless of seasonal changes in room temperature, thereby keeping the amount of vaporization constant.

Although the heating element 12 is shown as a resistor in the figure, it may be a power source for generating high voltage, and a light bulb, a motor, etc. can also produce the same effect as long as it generates heat during operation.

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 ionized wind, and A reducing gas vaporization port is installed in a part of the tank, and a heating element is installed near the reducing gas generating container, so the gas liquid can be kept at a constant temperature and a fixed amount of reducing gas can be volatilized regardless of the season. ,
Ozone generated when ion wind is induced can be efficiently reduced with a reducing gas to reduce ozone, and the reducing gas is not wasted and the required amount can be kept constant. Furthermore, when not in operation, the temperature of the gas liquid is low and there is no air flow, so the amount of volatilization is extremely small, making it possible to generate gas more effectively.
