BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone deodorizer for decomposing odors.

0002

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 2, this type of ozone deodorizer includes a power supply battery 21, a switch 22, and a first switch that stops after a first predetermined time has elapsed from the operation of the switch 22. a timer 23, a second timer 24 that starts when the first timer stops and stops after a second predetermined time has elapsed; a third timer 25 that stops after a specified time period has elapsed and restarts the first timer; a suction fan motor 26; a fan motor drive FET 27; an ozone discharge body 28; While the driving ozone supply circuit 29 and the first and second timers 23 and 24 are operating, an on signal is generated to the FET 27, and the ozone generation circuit 29 is turned on while the first timer 23 is operating. It consisted of a control section that generated signals and a honeycomb-shaped catalyst body.

The operation of the ozone deodorizer constructed as described above will be explained. First, the first timer 23 recognizes the operation of the switch 22 and starts. In response to this, the control unit 30 outputs an ON signal to the FET 27 to rotate the suction fan motor 26 and simultaneously generate ozone from the ozone discharge body 28 through the ozone generation circuit 29.

[0004] After the first time has elapsed, the first timer 23 stops and the second timer 24 starts. In response to this, the control section 30 outputs an off signal to the ozone generation circuit 29 in order to stop ozone generation. After the second time period has elapsed, the second timer 24 is stopped and the third timer 25 is started. In response to this, the control section 30
Outputs an off signal to the FET 27 and turns the suction fan motor 26
to stop. Thereafter, when the predetermined time of the third timer has elapsed, the third timer 25 stops, the first timer 23 starts again, and this operation is repeated. This timing chart is shown in FIG. 3(b).

[Problems to be Solved by the Invention] However, with the above-mentioned conventional configuration, the low concentration of odor present in the air is inhaled and this is chemically reacted with ozone in the air, so the probability of the combination of odor and ozone is low. In order to increase the bonding probability, it is necessary to generate more ozone than is required for decomposition, which poses a problem in that extra power is required.

[0006] The present invention solves the above-mentioned problems of the conventional art, and first rotates only the suction fan motor by operating a switch, then also generates ozone for a certain period of time, and then rotates only the suction fan motor again. I tried to let him do it.

[0007] As a result, low-concentration odors that initially exist in a relatively wide area of the air are physically adsorbed on the catalyst body placed in an extremely narrow space, and the odors that can be decomposed only by the catalyst body are decomposed, and then the remaining odors are decomposed. The amount of ozone necessary for The purpose of this invention is to provide an ozone deodorizer that effectively utilizes ozone.

[0008]

[Means for Solving the Problems] In order to achieve this object, the ozone deodorizer of the present invention includes a switch that is operated at any time and a switch that is stopped after a first predetermined period of time has elapsed from the operation of the switch. a first timer; a second timer that starts when the first timer stops and stops after a second predetermined time; a third timer that starts when the second timer stops; a third timer that stops after a predetermined time elapses; and a fourth timer that starts from when the third timer stops, stops after a fourth predetermined time elapses, and restarts the first timer. an ozone supply unit comprising a suction fan motor, an ozone discharge body and an ozone generation circuit, a honeycomb-shaped catalyst body, and a suction fan motor during operation of the first, second, and third timers; and a control section that operates the fan motor and operates the ozone supply section while the second timer is operating.

[0009]

[Operation] With this configuration, only the suction fan motor can be rotated when the first and third timers are operating, and ozone can also be generated when the second timer is operating.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 3(a). In Figure 1, 1
2 is a power source battery; 2 is a switch that the user operates when the user is concerned about the smell; and 3 is a first timer that stops when a first predetermined time has elapsed from the operation of the switch. Reference numeral 4 indicates a second timer that starts when the first timer 3 stops and stops after a second predetermined time has elapsed; 5 indicates a second timer that starts when the second timer 4 stops; A third timer 6 starts when the third timer 5 stops and stops after a fourth predetermined time has elapsed, and again the first timer 5. This is the fourth timer that starts timer 3. 7 is a suction fan motor, 8 is an FET for driving the suction fan motor, 9 is an ozone discharge body, and 10 is an ozone generation circuit that drives the ozone discharge body 9. 11 generates an ON signal to the FET 8 while the first, second, and third timers 3, 4, and 5 are operating, and generates an ON signal to the ozone generation circuit 10 while the second timer 4 is operating. This is the control section that generates the signal. A catalyst body (not shown) is installed between the ozone discharge body 9 and the suction fan motor 7.

The operation of the ozone deodorizer constructed as above will be explained below. First, the first timer 3 recognizes the operation of the switch 2 and starts. In response to this, the control unit 11 outputs an on signal to the FET 8,
The suction fan motor 7 is rotated.

After the first time has elapsed, the first timer 3 stops and the second timer 4 starts. In response to this, the control section 11 generates ozone from the ozone discharge body 9 through the ozone generation circuit 10, and after the second time has elapsed, the second timer 4 stops and the third timer 5 starts. In response to this, the control unit 11 outputs an off signal to the ozone generation circuit 10 in order to stop ozone generation, and after the third time has elapsed, the third timer 5 stops and the fourth timer 6 starts. .

In response to this, the control section 11 outputs an off signal to the FET 8 in order to stop the suction fan motor 7. Then, when the fourth set time has elapsed,
The fourth timer 6 stops, the first timer 3 starts again, and this operation is repeated. This timing chart is shown in FIG. 3(a).

As described above, according to the present invention, the first and second
, When the third timer is operating, only the suction fan motor is rotated, when the second timer is operating, both ozone generation and the suction fan motor are operated, and when the fourth timer is operating, the ozone generation and suction fan motor are operated. can be suspended together.

[0015]

[Effect of the invention] A suction motor is used to physically adsorb low-concentration odors that exist in a relatively wide space onto a catalyst body placed in an extremely narrow space, and odors that can be decomposed by the catalyst body alone are decomposed. Odors that cannot be decomposed are adsorbed onto a catalyst body to increase their concentration. Then, while the suction motor is rotating, ozone is generated, which chemically decomposes the odor around the ozone discharge body and generates ozone. It is sent to the catalyst body to decompose the undecomposed odor adsorbed on the catalyst body.

[0016] After that, the ozone discharge is stopped, and the ozone existing in a relatively wide space is sucked by the suction fan motor, and the ozone is reduced to oxygen by the catalyst body, and the rotation of the suction fan motor and the generation of ozone are stopped for a certain period of time. Afterwards, by starting the initial operation again, the relatively small catalyst body and ozone discharge body reduce wasted excess ozone and efficiently decompose a large amount of odor, making it odorless, even though it uses batteries as a power source. It can decompose low-concentration odors that exist in a wide range of spaces with a small amount of electricity.
