Abstract

PROBLEM TO BE SOLVED: To efficiently deorodize an odor in a wide space within a short period of time by a method wherein air is fed by a specified air feeding pressure, and moisture in the air is resonantly excited by a near infrared ray of a specified wave length and a far infrared ray electromagnetic wave, and active oxygen is created, and the odor particles are decomposed. SOLUTION: Air is drawn from a suction port 2 by a fan 5, and pressurized, and the air containing an odor is fed to an active oxygen creating member 7 which is provided on the other side. The active oxygen creating member 7 is formed of a raw material which irradiates a near infrared ray of which the wave length is 2.5-3.2 μm, and a far infrared ray electromagnetic wave of which the wave length is 5.9-7.4 μm, e.g. an electromagnetic wave emitting ceramic. When the air containing the odor passes through the active oxygen creating member 7, water particles in the air are resonantly excited, and active oxygen is created. By the active oxygen, the odor particles are decomposed and eliminated. Thus, an odor which is dispersed in a wide space can be efficiently deodorized within a short period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device capable of surely and efficiently deodorizing various odors which diffuse in a relatively wide space.

[0002]

2. Description of the Related Art As means for removing odors, a method of masking odor molecules by diffusing an aromatic gas stronger than the odors has been used, and the odor molecules to be diffused are adsorbed and removed in the pores of a porous substance. A method of decomposing odor molecules with ozone, fluorine gas or the like is known. By the way, in these odor removing means, the masking method has a selectivity of likes and dislikes for the peculiar fragrance itself, and furthermore, ozone and fluorine gas are highly dangerous and are limited to use in an industrially closed space. Therefore, at present, a method of adsorbing on a porous material such as activated carbon or zeolite is widely used.

However, in the method of adsorbing on a porous material such as activated carbon or zeolite, air containing odor molecules diffused over a wide area must be removed from the porous material in order to deodorize odors diffused over a relatively wide space. Although it is desired to contact and circulate the material, in order to contact and circulate air containing odor molecules in a large number of fine holes, the air must be blown at an extremely high blast pressure. Odor molecules are gradually adsorbed in the substance and are gradually blocked.
Since the amount of contact flow decreases remarkably with the decrease in adsorbability, an extremely powerful blower must be installed for deodorization in a wide space, and the porous adsorbent must be replaced frequently. I have a problem that needs to be addressed.

[0004] The inventors of the present invention have conducted intensive studies in view of such a problem. As a result, many odor molecules can be decomposed and eliminated safely and reliably with active oxygen having high reactivity and strong oxidative decomposition power. It can be created by effectively exciting the water molecules in the air in which molecules are diffused and mixed, and the water molecules have near-infrared electromagnetic waves having wavelengths of 2, 5 to 3, and 2 μm, and wavelengths of 5, 9 to 7 The inventors of the present invention have studied that resonance excitation is caused by an electromagnetic wave in the far-infrared electromagnetic wave region of 4 μm, and have reached the present invention.

[0005]

That is, the present invention decomposes the odor molecules by creating the active oxygen by exciting the water molecules in the air while causing a large amount to flow through the air in which the odor is diffused without causing resistance. An object of the present invention is to provide a deodorizing apparatus which can eliminate odors which are eliminated and diffused in a wide space safely and efficiently in a short time.

[0006]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is to provide an air inlet on one side of an appropriate casing and to diffuse odor to be sucked inside the air inlet. An appropriate filter for removing relatively large dust in the mixed air is detachably attached,
A fan for maintaining a required air blowing capacity is provided inside the filter, and an electromagnetic wave that resonates and excites water molecules in the air that comes into contact with the air blowing is provided on the inner surface of the other casing that is blown and pressed by the fan. An active oxygen creating member made of a ceramic material that emits near-infrared light having a wavelength of 2, 5 to 3, and 2 μm and far-infrared radiation having a wavelength of 5, 9, 7 to 4, and 4 μm in an appropriate shape to radiate is provided. The present invention is directed to a deodorizing apparatus having a configuration in which air that has been brought into contact with the active oxygen generating member by blowing air is supplied from air supply ports provided in casings in the left and right directions parallel to the active oxygen generating member.

[0007]

The technical means of the present invention has the following functions. That is, the air in which the odor is diffused and mixed is taken in from the intake port with a volume substantially equal to the air blowing capacity with the rotation of the fan, and the relatively large mixed dust and the like is removed in advance by the filter. Then, the air, in which the odor blown by the fan is diffused and mixed, is brought into contact with the active oxygen generating member provided on the other side at a required blowing pressure, and flows along the active oxygen generating member. The active oxygen generating member emits near-infrared rays having a radiation wavelength of 2, 5 to 3, and 2 μm and far-infrared rays having a wavelength of 5, 9 to 7, and 4 μm. Water molecules in the air are resonantly excited to create active oxygen, and odor molecules are instantaneously decomposed and eliminated. Furthermore, since the air blown by the fan and in contact with the active oxygen generating member and flowing therethrough is blown from the respective air inlets provided in the left-right direction parallel to the active oxygen generating member, resistance to blowing is reduced. Extremely large capacity air can be blown without it.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view showing the structure of the present invention. FIG. 1 is an explanatory view showing the structure of the present invention. Since a material having excellent properties is desired, a metal plate is generally used. One side of the casing 1 is provided with an intake port 2 for inhaling air in which odor in a wide space is diffused and mixed, and the intake port 2 has a diameter corresponding to a required intake capacity. It is determined and usually drilled in the casing 1 in a circular shape having a required diameter.

A filter 3 of an appropriate material and shape for removing relatively large dust and the like floating in air in which odor is diffused and mixed is provided inside the casing 1 having the intake port 2 formed therein. It is detachably attached to the casing 1 by appropriate means. That is, the present invention is intended to safely and efficiently deodorize odors diffused in a relatively large space in a short time, and an air conditioner such as an air conditioner is commonly used in a large space such as an office or a store. Therefore, in the filter 3 used in the present invention,
The mesh may be of such a size as to remove intrusion of solids or the like which may damage the present invention by inhalation, and when used with a large intake capacity, the intake pressure is also greatly increased so that sufficient toughness is obtained. Since it is required, a filter material obtained by weaving a stainless wire into a mesh of 10 to 50 mesh is preferable as a specific filter material.

Then, the filter 3 is connected to the casing 1
There is no particular limitation on the means for detachably mounting the inside of the filter, and any means can be used as long as the filter 3 can be freely removed when the filter 3 becomes dirty. As a specific example, as shown in FIG. What is necessary is just to form the insertion holding groove 4 which can be inserted and held inside the casing 1.

[0011] Inside the filter 3, air containing odor diffused into a required space is sucked in and deodorized and sent so that air can be sufficiently circulated through the space. A fan 5 for maintaining the air supply capacity is provided, and the fan 5 is rotatably mounted by a drive motor 6, so that the air intake and deodorization air supply amount can be adjusted to cope with a wide range of space. Thus, it is desirable that the drive motor 6 be designed so that the rotation speed can be changed.

Thus, air is sucked from the intake port 2 and the fan 5
On the inner surface of the casing 1 on the other side opposite to the air containing the odor blown by pressurized air, the air containing the odor blown by the appropriate shape, preferably pressurized and blown, is contacted and circulated as much as possible,
An active oxygen generating member 7 is provided to effectively generate resonance oxygen by causing water molecules in the air containing the odor to be resonantly excited, thereby efficiently decomposing and eliminating the odor molecules. That is, in the present invention, active oxygen such as singlet oxygen, superoxide, hydroxy radical or hydrogen peroxide having high reactivity and strong oxidative decomposition power is excited by resonance excitation of water molecules in the air in which odor molecules diffuse and coexist. Since the active oxygen generating member 7 is for generating and decomposing and eliminating odor molecules, the active oxygen generating member 7 has near-infrared rays having wavelengths of 2, 5 to 3, and 2 μm, which are effective resonance excitation of water molecules, and wavelengths of 5, 9 to 7 A material having a radiation characteristic of a 4 μm far-infrared electromagnetic wave is selected.

Various materials can be proposed as materials having such near-infrared and far-infrared electromagnetic wave radiation characteristics. As specific materials, 30 to 60% by weight of silicon oxide and 20 to 40% by weight of aluminum oxide are used as main components. ,
The transition element oxide is selected from manganese oxide, iron oxide, cobalt oxide, nickel oxide, and titanium oxide.
An electromagnetic wave radiation ceramic material obtained by calcining 7 to 15% by weight of one to three kinds of transition element oxides and 5 to 10% by weight of zinc oxide as a catalyst for promoting electromagnetic wave radiation.

In addition, what is required of the active oxygen generating member 7 is to allow air containing odor blown by the fan 5 to be contacted and circulated as much as possible and to increase the contact surface area ratio. Specifically, as shown in FIG. 2, an electromagnetic radiation particle 71 having a small particle diameter made of an electromagnetic radiation ceramic material is fixed to one side surface of an appropriate plate-like base material 70 as shown in FIG. As shown in FIG. 4, a side surface of a plate-like base material 72 made of an electromagnetic radiation ceramic material is embossed 73, or a corrugated base material 74 formed by shaping an electromagnetic wave radiation ceramic material into a corrugated plate as shown in FIG. Is preferred.

The fan 5 blows air under pressure and comes into contact with the surface of the active oxygen generating member 7 to send air in which odor molecules are decomposed and eliminated by the generated active oxygen without any resistance. In addition, the deodorizing device 9 of the present invention is formed by providing a gas supply port 8 in the casing 1 in the left-right direction parallel to the active oxygen generating member 7. The port 8 is formed with a diameter that allows air to be sent without adding resistance to the amount of air suctioned from the air inlet 2 by the fan 5.

[0016]

The present invention has the above-mentioned construction, and air containing a required amount of odor is sucked in from a suction port depending on the number of rotations of a fan, and is blown under pressure by the fan to make contact surface area ratio. Contact with the active oxygen generating member having a large size, and the air is supplied from an air supply port provided in the left-right direction parallel to the active oxygen generating member. Large capacity air circulation can be achieved with a fan. The air containing the odor contacted with the active oxygen generating member by being blown under pressure by a fan is resonantly excited by the radiated electromagnetic waves of the mixed water molecules to create active oxygen and is instantaneously decomposed and eliminated. The odor that diffuses into the space is also circulated in a short time, so that the odor can be eliminated. Furthermore, in the present invention, active oxygen is created from water molecules mixed with odor molecules, so that odor molecules are not only reliably decomposed and eliminated, but also have an antibacterial effect against bacteria and fungi floating in the air. Is extremely safe to use because of the active oxygen created from water molecules. In addition, since electromagnetic radiation is radiated as long as temperature energy is present, it can be said that this is a deodorizing device having excellent features such as a semi-permanent deodorizing effect.
