Description

[0001]
[Industrial applications]
The present invention relates to a deodorizing / sterilizing apparatus for deodorizing / sterilizing indoor air and the like using at least an ozone lamp that generates ozone.
[0002]
[Prior art]
An ozone lamp constituted by a mercury lamp generating ultraviolet rays having a wavelength of about 185 nm, a germicidal lamp constituted by a mercury lamp generating ultraviolet rays having a wavelength of about 250 nm, or an ultraviolet lamp emitting the ultraviolet rays having these wavelengths simultaneously is used. Japanese Patent Application Laid-Open Nos. 61-244267 and 61-279248 disclose a method of deodorizing and sterilizing air in places where a relatively large number of people enter and exit, such as hotels, inns, and hospitals. I have.
[0003]
Also, if the ozone concentration in the air is high, there is a problem that the human body such as a headache is affected, and the ozone concentration in the air is detected by an ozone sensor, and when the ozone concentration reaches a predetermined value or more, the ozone lamp is turned off. The applicant of the present invention has proposed a device for stopping generation of ozone, for example, in Japanese Patent Application No. 6-31246.
[0004]
[Problems to be solved by the invention]
On the other hand, the deodorizing sterilizer has a relatively compact structure in which an ozone lamp, a circulation fan, and a circuit board for control are mainly arranged in a casing. If it is arranged between the holes, a part of the ultraviolet light emitted from the ozone lamp is directly radiated to the ozone sensor, and there is a problem that the detection accuracy of the ozone concentration is reduced.
[0005]
Therefore, an object of the present invention is to provide a relatively simple configuration so that ultraviolet rays emitted from an ozone lamp are not directly emitted to an ozone sensor.
[0006]
[Means for Solving the Problems]
According to the present invention, at least an ozone lamp and a circulating fan that sucks external air into the casing from an intake hole provided at an appropriate position in the casing, circulates the air around the ozone lamp, and then ejects the air from an outlet hole are provided in the casing. And an ozone lamp is located between the intake port and the outlet port, and a circulating fan is disposed close to the inside of the outlet port, and the air sucked from the intake port is provided between the ozone lamp and the intake port. An ozone sensor for detecting the concentration of ozone in the ozone sensor, a partition plate is provided between the ozone lamp and the ozone sensor, and the ozone sensor is mounted on the non-opposing surface of the ozone lamp of the partition plate. Things.
[0007]
Further, according to the present invention, an intake hole is formed in a bottom surface of a casing, and a discharge hole is formed in an upper front surface or a side surface of the casing, and a partition plate is provided in the casing to form a ventilation path communicating the intake hole with the discharge hole. The ozone lamp is disposed horizontally above the air inlet of the air passage, and a partition plate is provided between the ozone lamp and the air inlet of the air passage. The ozone sensor is installed at the approximate center of the non-opposite surface of the, and a space for ventilation is formed between both ends of the partition plate and the partition plate, and the ozone sensor faces between the partition plate and the intake hole. And a guide plate having ventilation holes formed therein.
[0008]
[Action]
By turning on the ozone lamp and activating the circulation fan, the air in the room or the like is sucked into the casing from the air intake hole, circulates around the ozone lamp, and deodorized and sterilized by turning on the ozone lamp. It is released from the outlet.
[0009]
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.
[0010]
On the other hand, according to the present invention, by disposing a partition plate between the ozone lamp and the ozone sensor, the partition plate prevents ultraviolet rays radiated from the ozone lamp from being emitted to the ozone sensor, thereby preventing malfunction of the ozone sensor. I do.
[0011]
Further, according to the present invention, the partition plate and the guide plate are disposed between the ozone lamp and the intake hole, thereby preventing radiation from the ozone lamp to the ozone sensor radiated by the partition plate and allowing the casing to be radiated from the intake hole to the inside of the casing. Thus, the air sucked into the air can surely pass through the ozone sensor, and the ozone concentration can be more accurately detected by the ozone sensor.

【Example】
DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. Reference numeral 1 denotes a deodorizing sterilizer main body, which has a plurality of slit holes formed in a front upper portion of a casing 2 and a plurality of slit holes formed on a bottom surface. And a convex ventilation path 5 communicating the intake hole and the outlet hole 3 is defined by a partition plate 6 therein.
[0013]
Reference numeral 7 denotes an ozone lamp disposed horizontally above the intake hole 4 in the ventilation path 5, and is constituted by a quartz glass low-pressure mercury lamp which emits ultraviolet rays having a wavelength of 184.9 nm, for example.
[0014]
Reference numeral 8 denotes a circulation fan disposed inside the air outlet 3 of the ventilation path 5. The circulation fan sucks air in a room or the like into the ventilation path 5 from the intake hole 4 by rotation, and then circulates around the ozone lamp 7. It is configured so as to be blown out again into the room or the like from the blowout hole 3.
[0015]
Reference numeral 9 denotes a partition plate which is located between the intake hole 4 of the ventilation path 5 and the ozone lamp 7 so as to partition the inside of the ventilation path 5 substantially in parallel with the ozone lamp. Are provided with ventilation gaps 10, 10.
[0016]
Reference numeral 11 denotes a guide plate located between the intake hole 4 and the partition plate 9 and arranged so as to partition the air passage 5 substantially in parallel with the partition plate. I have.
[0017]
The guide plate 11 is formed by bending the lower end of a mounting plate 13 fixed to the inner surface of the casing 2 behind the ozone lamp 7 forward, and the mounting plate supports both ends of the ozone lamp 7. The plates 14 and 14 are bent, and the partition plate 9 is fixed to the front surface of the mounting plate 13.
[0018]

[0019]
Numerals 17 and 17 denote control circuit boards arranged in the space between the casing 2 and the partitioning plate 6. After the air is sucked into the ventilation path 5 and circulated around the ozone lamp 7, the air is blown out from the outlet 3, and the ozone concentration in the circulating air is detected by the output of the ozone sensor 15. When the concentration reaches 1 ppm or more, the ozone lamp 7 is turned off to deodorize and sterilize the air.
[0020]
By turning on the ozone lamp 7 and rotating the circulation fan 8 during operation, air in the room where the deodorizer / sterilizer main body 1 is installed or the like is sucked into the air passage 5 in the casing 2 from the intake hole 4. After passing through the ozone sensor 15 through the vent hole 12, it circulates around the ozone lamp 7 through the intervals 10 and 10, and then discharges from the outlet 3.
[0021]
As a result, the air sucked from the intake hole 4 reliably passes through the ozone sensor 15 by the guide plate 11 and the partition plate 9, and detects the ozone concentration of the passing air.
[0022]
When the ozone lamp 7 is turned on, ultraviolet rays are emitted from the surface thereof, but a part of the ultraviolet rays is blocked by the partition plate 9 and is not directly radiated to the ozone sensor 15, thereby preventing the ozone sensor from malfunctioning due to the radiation. .
[0023]
【The invention's effect】
According to the configuration of the present invention, the radiation of the ultraviolet rays emitted from the ozone lamp to the ozone sensor is blocked by the partition plate, and the malfunction of the ozone sensor due to the radiation can be prevented, and the ozone sensor is fixed to the partition plate. It is also possible to reduce costs and improve workability by reducing the number of parts.
[0024]
In addition, the present invention provides a partition plate and a guide plate between an intake hole and an ozone lamp, and also provides a ventilation space and a ventilation hole in these, so that air stays around the ozone sensor. Instead, the ozone sensor can reliably detect the ozone concentration by reliably passing the air sucked from the intake hole through the ozone sensor.
