Abstract

PURPOSE: To prevent the ultraviolet rays emitted from an ozone lamp from being directly radiated on an ozone sensor by arranging a partition plate between the ozone lamp and the ozone sensor, and by fitting the ozone sensor on the reverse surface of the partition wall opposite to the ozone lamp. CONSTITUTION: A partition plate 9 is arranged between the inlet port 4 of an air passage 5 and an ozone lamp 7 so as to be nearly in parallel with the ozone lamp and to partition the inside of the air passage 5. Air-passage gaps 10, 10 are provided between both ends of the partition plate 6 and the partition plates 6 by which the air passage 5 communicating the inlet port 4 with the blowing-out port 3 is partitioned in a projected shape. A guide plate 11 is arranged between the inlet port 4 and the partition plate 9 so as to partition the air passage 5 nearly in parallel with the partition plate 9, and air holes 12 are perforated therein. An ozone sensor 15 is fitted in the part being opposite to the air holes 12 of the partition plate 9. The ozone lamp 7 is supported on a supporting plate 14 on the opposite side of the ozone sensor with a partition plate 9 therebetween.

On the other hand, in the deodorizing and sterilizing apparatus, since the ozone lamp, the circulation fan and the control circuit board are mainly arranged in the casing, the apparatus is relatively compact. If the sensor is arranged between the ozone lamp and the intake hole in the casing, there is a problem that a part of the ultraviolet rays emitted from the ozone lamp is directly radiated to the ozone sensor and the detection accuracy of the ozone concentration is lowered.

Therefore, the present invention has a relatively simple structure.
The purpose is to prevent ultraviolet rays emitted from the ozone lamp from being directly emitted to the ozone sensor.

In the case where an ozone sensor for detecting the ozone concentration in the air sucked from the intake hole is provided, a partition plate is provided between the ozone lamp and the ozone sensor, and the ozone lamp of the partition plate does not face each other. The surface is equipped with an ozone sensor.

Further, according to the present invention, an intake passage is formed in the bottom surface of the casing, and an outlet hole is formed in the upper front surface or side surface of the casing, and a partition plate is provided in the casing to connect the inlet hole to the outlet hole. And the ozone lamp is horizontally arranged above the intake hole of the ventilation path, and the partition plate is disposed between the ozone lamp and the intake hole of the ventilation path.
An ozone sensor is attached to the partition plate at approximately the center of the non-opposing surface of the ozone lamp, a ventilation gap is formed between both ends of the partition plate and the partition plate, and between the partition plate and the intake hole. To
A guide plate having a vent hole is arranged facing the ozone sensor.

[0008]

[Function] By turning on the ozone lamp and operating the circulation fan, the air in the room is sucked into the casing through the intake hole, circulates around the ozone lamp, and deodorizes and sterilizes when the ozone lamp turns on. After that, it is discharged from the outlet.

Further, the ozone sensor detects the ozone concentration of the air sucked from the intake hole, and when the ozone concentration is higher than a predetermined value, the ozone lamp is turned off to stop the generation of ozone.

On the other hand, according to the present invention, the partition plate is provided between the ozone lamp and the ozone sensor, so that the partition plate prevents the ultraviolet light emitted from the ozone lamp from being radiated to the ozone sensor. Prevent malfunction.

Further, according to the present invention, the partition plate and the guide plate are disposed between the ozone lamp and the intake hole, so that the partition plate prevents the ozone sensor from emitting the ozone lamp and the intake hole. The air sucked into the casing from the casing can surely pass through the ozone sensor, and the ozone concentration can be detected more accurately by the ozone sensor.

A circuit board for control disposed in a space between the air-conditioning device and the circulation fan 8 or ozone lamp 7 during operation so that air in the room or the like is sucked into the ventilation passage 5 from the intake hole 4 during operation. The ozone lamp 7 circulates around the ozone lamp 7 and then is ejected from the blowout hole 3 and the ozone concentration in the circulating air is detected by the output of the ozone sensor 15. When the ozone concentration reaches 0.1 ppm or more, the ozone lamp 7 is turned off. Deodorize and sterilize in the air.

During operation, the ozone lamp 7 is turned on and the circulation fan 8 is rotated, so that the air in the room where the deodorizer / sterilizer main body 1 is installed is introduced from the intake hole 4 into the ventilation passage 5 in the casing 2. After passing through the ozone sensor 15 through the ventilation hole 12, it circulates around the ozone lamp 7 through the intervals 10 and 10, and then is discharged from the blowout hole 3.

As a result, the air sucked through the intake holes 4 reliably passes through the ozone sensor 15 by the guide plate 11 and the partition plate 9, and the ozone concentration of the passing air is detected.
