The best embodiment is to decompose the ozone contained therein into oxygen to reduce its concentration and to sterilize the air passing therethrough.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 3, the deodorizing and sterilizing apparatus 1 for a space and the like is placed on the floor in the space or the like, the main body case 3 has a space of a predetermined capacity inside, and an air flow is formed on the lower surface thereof. An inlet 5 is provided, and an air outlet 7 is provided on the upper surface. Furthermore, various setting members 3 a such as an operation mode setting switch and a timer setting dial of the deodorizing and sterilizing apparatus 1 for a space are provided on the upper surface of the main body case 3.

  The air inlet 5 described above is limited to the lower part of the main body case 3, but the air outlet 7 is a main body case in which air flowing in from the air inlet 5 can be discharged through an ozone unit 19 described later. 3 may be provided in the upper part.

  An air discharge base 9 is provided at the upper part of the main body case 3 corresponding to the air discharge opening 7, and a blowing member 11 such as an electric fan is provided in the air blowing direction in the air discharge base 9. , Exhaust the air inside. Further, an exhaust duct 13 whose bending angle can be freely adjusted is provided on the air discharge base 9 protruding outward from the upper surface of the main body case 3. The exhaust duct 13 is adjusted to be arbitrarily bent so as to face a desired discharge direction.

  A filter 15 is replaceably provided on the lower surface of the main body case 3 corresponding to the air inlet 5. The filter 15 is detachably attached to the engagement flange 17 provided on the lower surface of the body case 3 corresponding to the three-side periphery of the air inlet 5 so that the corresponding side edge is locked. .

An ozone unit 19 is provided in the main body case 3 according to the space between the air inlet 5 and the air outlet 7. The case 21 of the ozone unit 19 is a laterally lateral U-shape provided with an upper plate and a lower plate 21a, 21b with a horizontal length in contact with the front plate of the main body case 3, and the upper plate 21a and the lower plate 21b include A plurality of slit holes 23 and 25 that allow air to pass therethrough are formed, and ultraviolet light shielding plates 27 and 29 pass through the upper plate 21a and lower plate 21b corresponding to the slit holes 23 and 25, respectively. It is provided in a state that enables.

The front end face and the side end face of the upper plate 21a and the lower plate 21b are provided with an airtight material 21c that comes into contact with the inner surface of the corresponding side plate of the main body case 3 to be airtight, and the ozone unit 19 is hermetically sealed in the main body case 3. The air flowing in from the air inlet 5 passes through the ozone unit 19 and is discharged from the air outlet 7.

Note that the case 21 may have a box shape other than the above-described lateral lateral U-shape and a box shape with the front open. For the box-shaped case 21 whose front is open, an airtight material (not shown) is attached to the front side end face of the case 21, and when attached in the main body case 3, The air may be brought into contact and airtight, and the air flowing in from the air inlet 5 may pass through the case 21.

When the ultraviolet light shielding plates 27 and 29 are formed by punching a plurality of slit holes 23 and 25 on the upper surface and the lower surface of the case 21, punching remaining pieces of the slit holes 23 and 25 are formed at appropriate angles (for ozone generation described later). It is formed by tilting at an angle that reflects ultraviolet rays or ozone decomposing ultraviolet rays and can regulate leakage to the outside. Then, the air flowing in from the slit hole 23 on the lower surface is passed through the case 21 so as to flow out from the slit hole 25 on the upper surface.

A plurality of ozone generating ultraviolet light emitting members 31 such as an ultraviolet lamp and an ultraviolet light emitting diode and an ozone decomposing ultraviolet light emitting member 33 are provided inside the case 21. Each ozone generating ultraviolet light emitting member 31 dissociates oxygen in the air passing through the case 21 to generate ozone and outputs ozone generating ultraviolet light that sterilizes the passing air. Further, the ozone decomposing ultraviolet light emitting member 33 outputs ozone decomposing ultraviolet light that decomposes ozone in the air passing through the case 21 into oxygen and sterilizes the passing air.

Note that the ozone generating ultraviolet light emitting member 31 and the ozone decomposing ultraviolet light emitting member 33 provided in the case 21 adhere to dust or the like contained in the air flowing through the case 21 and generate ozone generating ozone or ozone decomposing. There is a risk of lowering the output of industrial ultraviolet rays. In order to prevent this, a transparent plate (not shown) capable of transmitting ozone generation ultraviolet light or ozone decomposition ultraviolet light into the case 21 according to the front surfaces of the ozone generation ultraviolet light emission member 31 and the ozone decomposition ultraviolet light emission member 33. In a hermetic form (tight enough to prevent dust and the like from entering) and restricts dust and the like from directly adhering to the ozone generating ultraviolet light emitting member 31 and the ozone decomposing ultraviolet light emitting member 33. Also good.

Next, the operation of the deodorizing and sterilizing apparatus 1 such as a space configured as described above will be described based on the usage mode.

First, in the case of deodorizing or sterilizing a living space or the like used by a person or the like, for example, after setting the deodorizing and sterilizing device 1 or the like in the living space or the like at night when the living space or the like is unattended When the power switch is turned on, the air blower member 11 is activated to take in the air in the living space or the like from the air inlet 5 and then passes through the ozone unit 19 to form an air flow exhausted from the air outlet 7. The ozone generating ultraviolet light emitting member 31 is turned on, and the ozone in the air passing through the ozone unit 19 is dissociated by the ozone generating ultraviolet light output from the ozone generating ultraviolet light emitting member 31 to generate and pass ozone. Sterilize the air.

As a result, the air exhausted from the air outlet 7 contains high-concentration ozone, so that the living space or the like is filled with high-concentration ozone. And the inside of a living space etc. is deodorized by the oxidation effect | action by the ozone in the air with which it fills in the living space etc., or a floating microbe and virus are sterilized.

The air passing through the deodorizing and sterilizing apparatus 1 such as a space is sterilized by the ozone generating ultraviolet light output from the ozone generating ultraviolet light emitting member 31, so that the air in the space or the like is caused by a synergistic effect with the sterilizing action by ozone. Sterilization efficiency is increased.

Then, when a predetermined time elapses after the ozone generating ultraviolet light emitting member 31 is turned on, the ozone generating ultraviolet light emitting member 31 is turned off to stop the generation of ozone and the ozone decomposing ultraviolet light emitting member. 33 is turned on, and the ozone decomposing ultraviolet light output from the ozone decomposing ultraviolet light emitting member 33 is circulated in the living space or the like and output to the air passing through the ozone unit 19 to decompose the contained ozone into oxygen. Then, the ozone concentration in the living space or the like is reduced and the passing air is sterilized.

At that time, ozone contained in the air is heavier than air and tends to accumulate in the lower part of the space or the like. However, the deodorizing and sterilizing apparatus 1 for the space of the present embodiment takes in the air in the space or the like from the lower part. Since it is comprised, ozone contained in the air can be efficiently decomposed and reduced in concentration.

Then, when ozone decomposing time by the ozone decomposing ultraviolet light emitting member 33 has passed a predetermined time, the ozone decomposing ultraviolet light emitting member 33 is turned off, and the driving of the air blowing member 11 is stopped to set the living space. The deodorization and sterilization such as are finished.

Note that the ozone decomposing ultraviolet light emitting member 33 may continue to be lit because the air in the living space has the action of decomposing ozone present in nature into oxygen.

At the time of generating ozone and decomposing ozone as described above, as shown in FIG. 4, the ozone generating and ozone decomposing ultraviolet rays output by lighting the ozone generating ultraviolet light emitting member 31 and the ozone decomposing ultraviolet light emitting member 33 are emitted. There is a risk of leaking outside through the slit holes 23 and 25 and adversely affecting the human body or the like in the living space. In this embodiment, the ultraviolet light shielding plates 27 and 29 provided corresponding to the slit holes 23.25 reduce the leakage of ultraviolet rays to the outside to prevent adverse effects on the human body and the like.

Further, dust or the like contained in the air flowing in from the air inlet 5 with the driving of the air blowing member 11 adheres to the ozone generating ultraviolet light emitting member 31 or the ozone decomposing ultraviolet light emitting member 33 and reduces the output of ultraviolet light. Ozone generation ability and ozonolysis ability may deteriorate. In the present embodiment, a filter 15 is provided at the air inlet 5, and the inconvenience described above can be eliminated by allowing the air from which dust or the like has been separated by the filter 15 to flow into the ozone unit 19.

Next, for example, even when deodorizing or sterilizing a space such as a warehouse, the ozone generating ultraviolet light emitting member 31 is turned on for a predetermined time to generate ozone and deodorize in the same manner as described above. However, the ozone emitting ultraviolet light emitting member 33 may be turned on to decompose residual ozone in the space or the like after the sterilization. After the light is turned off, the ozone remaining in the space or the like may be naturally decomposed without turning on the ultraviolet light emitting member 33 for ozone decomposition.

As for the operation mode of the deodorizing and sterilizing apparatus 1 such as a space, for example, an ozone generation / decomposition mode in which ozone generation is performed for a predetermined time after ozone generation is continued for a predetermined time, an ozone generation mode in which only ozone generation is performed for a predetermined time, An ozonolysis mode for performing only ozonolysis for a predetermined time may be provided so that it can be selected according to the application.

In the above description, the filter 15 is replaceably attached to the lower surface of the main body case 3 in accordance with the air inlet 5, but restricts the entry of dust or the like that clogs into the slit holes 23 and 25. It is good also as a structure which fixedly attached the metal mesh.
