Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone deodorizer which is installed at a place where an offensive odor is a concern and is used to eliminate the offensive odor.

[0002]

2. Description of the Related Art Conventionally, this type of ozone deodorizer has a structure as shown in FIGS. 2 in FIGS.
Reference numeral 1 denotes a power supply battery, which drives a fan motor 22 by the power supply battery 21 to generate ozone due to discharge of a discharge body 24 generated by an ozone generation circuit 23, which is then mixed with odorous air and then a honeycomb-shaped catalyst 25. The odorous component was oxidatively decomposed by passing it through to deodorize it, and excess ozone was returned to oxygen.

[0003]

In such a conventional structure, when the cross-sectional area of the air flow path (that is, the cross-sectional area of the honeycomb catalyst) is small, ozone and odorous air are uniformly mixed. However, if this cross-sectional area is increased in order to enhance the deodorizing ability, there is a problem that the uniformity of ozone mixing is impaired.

The present invention solves such a problem. As shown in FIGS. 1 and 2, in order to diffuse ozone generated from a discharge body in a wide discharge chamber as much as possible, a timer is provided to perform discharge. The fan is rotated or stopped in conjunction with the discharge of the body.When the discharge of the discharge body starts, the fan operates for a certain period of time, then stops, and then operates for a certain period of time. When the discharge is repeatedly stopped, the fan also stops.

[0005]

In order to solve the above problems, the present invention provides a timer for generating ON / OFF signals,
The fan motor is controlled by an ON / OFF signal of the timer, an ozone supply unit including an ozone generating circuit, and a honeycomb catalyst. The fan motor is intermittently operated by the timer during ozone generation. By changing the amount and speed of the air generated by the fan, the ozone generated from the ozone supply unit is diffused so as to be substantially uniform and passed through the catalyst.

[0006]

With this configuration, even if the discharge is concentrated locally, the air in the discharge chamber and the ozone generated by the discharge are sufficiently mixed and diffused, and the catalyst decomposes the odorous components into oxidative decomposition and surplus ozone. Is efficiently decomposed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. In the figure, reference numeral 1 is a battery, and a FET that switches by a timer 2 and a signal from the timer 2.
Is a power source for operating the fan motor 3 and the ozone generation circuit 4 which are repeatedly rotated and stopped by FETs at regular intervals. Reference numeral 5 denotes a discharge body, which forms a part of the ozone generation circuit 4. Reference numeral 6 denotes a control unit that changes the ON / OFF state at regular intervals by a timer. Reference numeral 7 is a honeycomb catalyst, 8 is an air inlet, and 9 is an air outlet.

Now, when the timer 2 operates, the fan motor 3 is repeatedly driven and stopped after a certain period of time, the discharge body 5 continues to discharge during that time, and supplies ozone to the odorous air around it. The air that has flowed in from the air suction port 8 produces a turbulent flow due to intermittent rotation and stop of the fan motor 3,
The ozone is evenly diffused and then guided to the honeycomb-shaped catalyst 7. Here, the odorous components and ozone are activated when they come into contact with the catalyst 7, and the oxidation and decomposition reactions are promoted. Then, the deodorized air is discharged from the discharge port 9.

[0009]

As described above, according to the present invention, ozone is uniformly diffused by the intermittent operation of the fan motor with the discharge body having a small area, so that the odor of air having a wide cross-sectional area can be decomposed. , Despite the small overall shape
It can deodorize a large space.
