Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing / sterilizing apparatus for deodorizing / sterilizing stored items such as shoes, slippers, clothes, etc. by using ozone in a storage box.

[0002]

2. Description of the Related Art In facilities such as hospitals and public facilities where many unspecified people come in and out, wear footwear etc. for the purpose of eliminating discomfort when visitors use the footwear etc. of the facility. A sterilizer for sterilization may be installed. Conventionally, as a sterilizing method, a method of irradiating ultraviolet rays using a sterilizing lamp is known, but the problem that it is not possible to sterilize parts that are not directly irradiated with ultraviolet rays and damage to footwear etc. that do not have ultraviolet resistance There is a problem that it cannot be applied because it is given. On the other hand, a sterilization method using ozone has long been known for sterilization in fields such as foods. However, since a high concentration of ozone is harmful to the human body, it is important to consider the effects on the human body in the sterilization method using ozone. Therefore, there has been proposed a sterilization device that supplies high-concentration ozone into the storage unit to sterilize the sterilization target, discharges ozone from the storage unit, and then takes out the sterilization target outside the storage unit ( For example, JP-A-7-16163).
However, as a deodorizing and sterilizing device used in a facility where an unspecified number of people come and go as described above, the footwear in the storage unit can be freely opened and closed without the operation of forcibly discharging ozone from the storage unit. It is desirable to develop a device that can keep ozone in the storage portion at a low concentration to the extent that it does not affect the human body so that the human body can be taken in and out.

[0003]

Fan 6 sucking into the ozone generating part 2 from the suction port 5 of
A deodorizing / bactericidal device comprising: an ozone decomposing catalyst 7 disposed between the ozone generator 1 and the suction port 5.

According to a second aspect of the deodorizing / sterilizing apparatus of the present invention, in the deodorizing / sterilizing apparatus of the first aspect, the ozone generator 1 is a lamp type ozone generator or a plasma resonance type ozone generator. Is characterized by.

The deodorizing / sterilizing apparatus of the invention according to claim 3 is the deodorizing / sterilizing apparatus according to claim 1 or 2, wherein a fan 6 is provided between the ozone generator 1 and the ozone decomposing catalyst 7. It is characterized by having set up.

In the present invention, the ozone generation amount is 0.5 to 10 m.
Ozone generator 1 with a small ozone generation rate of g / hour 1
The fan 6 is used to circulate the air containing ozone, and the ozone decomposing catalyst 7 is arranged between the ozone generator 1 and the suction port 5 of the ozone generator 2. It is possible to maintain a low concentration.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram for explaining an embodiment of the present invention. As shown in FIG. 1, the deodorizing / sterilizing apparatus according to the present invention includes an ozone generating section 2 in which an ozone generating apparatus 1 is installed, and a storage section 3 for a deodorizing / sterilizing object such as a slipper 8. A fan 6 for sending air containing ozone from the outlet 4 of the ozone generator 2 to the housing 3 and sucking the air in the housing 3 into the ozone generator 2 from the suction port 5 of the ozone generator 2. There is. The arrow in FIG. 1 indicates the flow of air containing ozone. Further, an ozone decomposition catalyst 7 is arranged between the ozone generator 1 and the suction port 5. Ozone in the storage unit 3 has a low concentration (specifically, 0.5 p
The ozone generator 1 of the present invention has an ozone generation amount of 0.5 to 10 mg so that the ozone generation amount can be maintained at
The lamp ozone generator and the plasma resonance type ozone generator can be exemplified. The fan 6 may be an electric motor fan, but is not particularly limited as long as it can circulate air containing ozone. For the installation position of the fan 6,
There is no particular limitation, but it is preferable to dispose it between the ozone generator 1 and the ozone decomposition catalyst 7 as shown in FIG. 1 because the air containing ozone can be circulated with certainty.

【Example】

(Embodiment 1) A lamp type ozone having the configuration shown in FIG. 1 and using a motor fan having an air flow rate of 0.5 m ³ / min as the fan 6 and an ozone generation amount of 2 mg / hour as the ozone generator 1. When a deodorizing / bactericidal device using a generator was manufactured and the ozone concentration in the storage unit 3 during operation was measured, it was confirmed that the concentration was constantly 0.05 ppm.

(Embodiment 2) A motor fan having the structure shown in FIG. 1 and an air flow rate of 0.5 m ³ / min is used as the fan 6, and the ozone generation amount of the ozone generation device 1 is 4 mg / hour. A deodorizing / bactericidal device using a lamp-type ozone generator was produced, and the ozone concentration in the storage unit 3 during operation was measured, and it was confirmed that the ozone concentration was constantly 0.1 ppm. .

(Embodiment 3) A motor fan having the structure shown in FIG. 1 and an air flow rate of 0.5 m ³ / min is used as the fan 6, and the ozone generation amount of the ozone generation device 1 is 8 mg / hour. A deodorizing / bactericidal device using a lamp-type ozone generator was produced, and the ozone concentration in the storage unit 3 during operation was measured, and it was confirmed that the concentration was constantly 0.2 ppm. .

(Comparative Example 1) A deodorizing / sterilizing apparatus having the same structure as in Example 1 except that the fan 6 was not installed was prepared, and the ozone generator 1 was in operation. When the ozone concentration in the storage unit 3 was measured, the ozone concentration increased with time and reached 4.5 ppm 10 minutes after the start of operation.

(Comparative Example 2) A deodorizing / sterilizing apparatus having the same structure as in Example 1 except that the ozone decomposing catalyst 7 was not installed was prepared. When the ozone concentration in the storage unit 3 during operation of No. 1 was measured, the ozone concentration increased with time and became 5 ppm 10 minutes after the start of operation.

[0014]

The deodorizing and sterilizing apparatus according to the present invention uses an ozone generator having a small ozone generation amount of 0.5 to 10 mg / hour, and circulates air containing ozone with a fan, and
