Description

  The present invention relates to a fan-equipped sterilizer suitable for use in removing a contamination source floating in the air.

  Conventionally, indoor air has various biological sources (for example, influenza virus, coronavirus, MRSA (methicillin-resistant Staphylococcus aureus), mold, allele substances (eg mite dead powder / dung, allele substances from pets). ] Or air pollution sources such as active oxygen are floating, which is harmful to the human body.

  In order to remove the harmful air pollution source from the air, various methods have been developed. As one of the effective devices, a sterilization comprising a cation generation unit and an anion generation unit is provided. There exists an apparatus (for example, refer patent document 1).

This sterilizer flows air from a cation generator to an anion generator, and first applies a positive high voltage to the air in the cation generator to decompose water molecules in the air to generate hydrogen ions ( H ⁺ ).
4H ₂ O → 2H ₂ O + O ₂ + 4H ⁺

On the other hand, a high voltage of a negative component is applied to the air in the anion generation unit to generate electrons (e ⁻ ) and oxygen ions (O ₂ ⁻ ).
O ₂ + e ⁻ → O ₂ ⁻

And when the hydrogen ion produced | generated by the said cation generating part approaches an anion generating part, a hydrogen ion will couple | bond with the electron produced | generated by the anion generating part, and will become a hydrogen atom (H).
H ⁺ + e ⁻ → H

Then, hydrogen atoms (H) and oxygen ions (O ₂ ⁻ ) are combined to generate hydroperoxy radicals (HOO ⁻ ). This hydroperoxy radical (HOO ⁻ ) surrounds and adheres to a positively charged biological source, destroying the hydrogen bonds of the protein structure on the surface of the biological source and destroying the biological source. The HOO-radical that reacted at the same time returns to water (H ₂ O) and returns to the air.

On the other hand, some of the hydrogen atoms (H) are combined with active oxygen (OH-radical) floating in the air, and become water molecules to neutralize the active oxygen (OH-radical).
H + OH → H ₂ O

  This active oxygen (OH-radical) is a substance having the strongest toxicity (oxidizing power) among active oxygen species, and is known as a causative substance such as skin aging and skin disease.

As described above, the sterilizing apparatus can effectively remove harmful air pollution sources from the air, and thus is effective for air purification. In order to effectively produce the above effect, air is made to flow in a straight line from the cation generator to the anion generator and the hydrogen ions (H ⁺ ) generated in the cation generator are reliably supplied. It is necessary to supply the anion generator.

JP 2006-34957 A

  As a means for supplying air to the sterilizer, it is conceivable to use a fan for blowing air. That is, if a sterilizer with a fan is configured by installing a fan in the vicinity of the sterilizer, air is blown to the sterilizer by driving the fan, from the cation generator to the anion generator of the sterilizer. The air flows and is discharged from the fan sterilizer while the air is purified. The exhaled air is circulated through the room, for example, thereby purifying the room air.

However, in the case of the sterilizer with a fan, since the air disturbed by the fan is blown directly to the sterilizer, the flow of air passing through the vicinity of the sterilizer does not become a uniform linear flow but becomes a turbulent flow. It has been difficult to reliably and smoothly supply the hydrogen ions (H ⁺ ) generated in the cation generation unit to the anion generation unit.

  In addition, air turbulent by the fan is released directly to the outside of the fan sterilizer, making it difficult for the sterilized and purified air to reach the distance efficiently, for example, effective sterilization / cleaning of the entire room. Cannot be converted. Increasing the fan output to circulate sterilized and purified air throughout the room will increasingly disturb the air flow and promote inefficient conditions.

  The present invention has been made in view of the above-described points, and an object of the present invention is to make the flow of air supplied to the sterilizer smooth and uniform, and to efficiently sterilize and clean the supplied air. It is intended to provide a fan-equipped sterilization apparatus that can effectively disinfect and clean the entire room, for example, by allowing the sterilized and cleaned air to efficiently reach far away. .

  According to the first aspect of the present invention, the inner cylinder portion is disposed in the outer cylinder portion through a gap serving as an air introduction path, and the upper portion of the outer cylinder portion is covered and an air intake is provided on the upper surface or side surface thereof. And a fan that is disposed above the inner cylinder portion in the case and blows out the air in the inner cylinder portion downward. A wind direction plate extending in the vertical direction protruding toward the center of the inner cylinder part is installed on the peripheral surface, and active hydrogen and oxygen ions are introduced into the inner cylinder part in the air flowing from the upper side to the lower side in the inner cylinder part. An sterilizer for supplying is installed, and an air introduction port for directly supplying air introduced from the lower opening of the air introduction path between the upper opening of the air introduction path of the case and the outer wall of the fan to the discharge side of the fan To the fan-equipped sterilization device That.

The invention described in claim 2 of the present application is the sterilization apparatus with a fan according to claim 1, wherein the sterilization apparatus discharges hydrogen ions from moisture in the air by plasma discharge by applying a high voltage of a positive component. A positive ion generation part for generating, and an anion generation part for generating electrons and superoxide anions (O ₂ ⁻ ) by plasma discharge by application of a high voltage of a negative component, and the positive electrode generation part in the inner cylinder part. A sterilization apparatus with a fan, wherein the cation generation unit is arranged on the upstream side and the anion generation unit is arranged on the downstream side so that the air flowing on the ion generation unit flows on the anion generation unit is there.

  The invention according to claim 3 of the present application is the sterilization apparatus with a fan according to claim 1 or 2, wherein the fan has a polygonal outer shape viewed from below and has a plurality of outer peripheries. With this fan installed on the upper end side of the inner cylinder part, the opening part of the inner cylinder part that protrudes outward from each outer periphery of the fan is used as the air introduction port. It is in the disinfection device.

According to the first and second aspects of the present invention, the air introduced from the air introduction port via the air introduction path between the outer cylinder part and the inner cylinder part is allowed to pass through the inside (suction side) of the fan. Without being directly supplied to the discharge side of the fan, the portion surrounding the outermost periphery of the downward air flow greatly disturbed by the fan can be wrapped in the air flow with little turbulence supplied from the air inlet. As a result, the flow of the entire air flow descending in the inner cylinder portion becomes smooth, and the air flow can be made a more linear flow by the wind direction plate installed in the inner cylinder portion. From these things, the flow of the whole air flow supplied to the sterilizer installed in the inner cylinder part can be made into a smooth uniform flow, and the supplied air can be sterilized and cleaned efficiently.
At the same time, the flow of the entire air flow blown downward (outside) from the fan-equipped sterilizer can be made smooth so that the blown sterilized / cleaned air can be efficiently distant (for example, For example, the entire room can be effectively sterilized and cleaned.

  According to the third aspect of the present invention, the air inlet port can be obtained by simply using a commercially available polygonal (mostly rectangular) fan as it is and installing it on the upper end side of the inner cylinder portion. Can be easily formed.

As shown in these drawings, the sterilization apparatus 1 with a fan includes a cylindrical case portion 60 in which an inner cylinder portion 40 is disposed in the outer cylinder portion 20 through a gap serving as an air introduction path 30, and an outer cylinder portion. A case 10 having an upper case portion 100 attached so as to cover the upper portion of 20, a fan 140 disposed above the inner cylinder portion 40 in the case 10, and above the fan 140 in the case 10. The apparatus control unit 160 to be installed and the pair of sterilizers 200 and 200 installed at the center of the inner cylinder unit 40 are configured.

  The cylindrical case portion 60 is formed by integrating an outer cylindrical portion 20, an inner cylindrical portion 40, a wind direction plate 80 described below, and a connecting plate 90 that connects the outer cylindrical portion 20 and the inner cylindrical portion 40 with an aluminum molded product. It is formed by molding (extrusion molding). The outer cylinder part 20 is formed in a cylindrical shape (cylindrical shape) whose upper and lower sides are released. The inner cylinder portion 40 is also formed in a cylindrical shape (cylindrical shape) whose upper and lower sides are released. A ring-shaped gap is formed between the outer cylinder part 20 and the inner cylinder part 40, and this gap forms the air introduction path 30. In other words, the inner cylinder part 40 is arranged in the outer cylinder part 20 through a gap that becomes the air introduction path 30. The air introduction path 30 has a ring shape with the upper and lower parts opened, and has substantially the same width dimension over the entire circumference.

  The outer cylinder part 20 and the inner cylinder part 40 are integrally connected by a plurality of (eight) connection plates 90 that pass through the air introduction path 30. The connecting plate 90 has a thin plate shape (band shape), extends linearly in the vertical direction, and is installed in a direction radiating from the central axis of the inner cylinder portion 40 at equal intervals. The connecting plate 90 connects the inner peripheral surface of the outer cylindrical portion 20 and the outer peripheral surface of the inner cylindrical portion 40 and extends from the vicinity of the upper end of the outer cylindrical portion 20 and the inner cylindrical portion 40 to the vicinity of the lower end. In addition to the function of connecting the outer cylinder part 20 and the inner cylinder part 40, the connecting plate 90 has a function of adjusting the flow of air passing through the inside upward, that is, a function as a rectifying plate. In every other four connecting plates 90 of the eight connecting plates 90, as shown in FIG. The fan mounting portion 91 extends from the upper end to the lower end of the connecting plate 90, and a screw threading hole 93 extending vertically is provided at the center thereof.

  A plurality (four) of wind direction plates 80 extending in the vertical direction projecting toward the center (center axis) of the inner cylinder portion 40 are installed on the inner peripheral surface of the inner cylinder portion 40. Each wind direction plate 80 has a thin plate shape (strip shape), its plane faces radially outward and up and down from the central axis of the inner cylinder portion 40, and extends from the vicinity of the upper end of the inner cylinder portion 40 to the vicinity of the lower end thereof. They are installed at regular intervals (90 ° intervals) when viewed from the central axis.

  The upper case portion 100 is configured by integrally molding a cylindrical (cylindrical) outer peripheral side wall 110 and an upper surface portion 130 closing the upper surface of the outer peripheral side wall 110 with a synthetic resin. That is, the upper case part 100 is formed in a shape in which the cup with the lower surface opened is turned down. A slit-like air intake 120 is formed at a position from the outer peripheral side wall 110 to the upper surface part 130 of the upper case part 100. Screw insertion holes 131 extending in the vertical direction are provided at a plurality of equally spaced locations (four locations) in the vicinity of the outer periphery of the upper surface portion 130 of the upper case portion 100. These screw insertion holes 131 are provided at positions facing the respective screw screw holes 93 of the cylindrical case portion 60. In order to form these screw insertion holes 131, as shown in FIG. 1, a cylindrical projecting portion 133 projects from the lower surface of the upper surface portion 130. A hanging tool attaching portion 135 is attached to a position facing the outer surface of the outer peripheral side wall 110 at 180 °. The hanging tool attaching part 135 is configured to have a structure in which both ends of the hanging tool 136 can be rotated and fixed at a predetermined angle. The hanging tool 136 is formed by bending a band-shaped metal plate into a U-shape, and a connector 137 made of a socket is attached to an intermediate position thereof.

  A device control unit 160 is attached to the center of the lower surface of the upper surface unit 130, and an operation knob 161 for operating the device control unit 160 is installed on the upper surface of the upper surface unit 130. The device control unit 160 is electrically connected to the connector 137 by a lead wire 163 that passes through the center of the upper surface portion 130, and although not shown, between the device control unit 160 and the fan 140 and the device control unit 160. The sterilizer 200 is also electrically connected by a lead wire. The device control unit 160 converts the power supply voltage input from the connector 137 into a predetermined voltage and supplies it to the fan 140 and the sterilizer 200. The operation knob 161 adjusts the rotational speed of the fan 140, for example.

  FIG. 4 is a view of the fan 140 and the cylindrical case 60 as seen from above with the upper case portion 100 shown in FIG. 1 removed. As shown in FIG. 1 and FIG. 1, the fan 140 includes a propeller-type blade 151 inside a fan case 141 and a fan motor 153 that is positioned at the center of the blade 151 and rotationally drives the blade 151. It is configured. The fan case 141 is configured by connecting a pair of rectangular (square) flat plate portions 143 and 145 positioned above and below by a cylindrical outer wall 147. An air suction port 148 and an air discharge port 149 that open up and down the outer wall 147 are provided. As described above, since the fan motor 153 is installed in the center of the outer wall 147, the air suction port 148 and the air discharge port 149 are both ring-shaped with substantially the same shape and size. This fan 140 is a commercially available fan.

  FIG. 5 is a perspective view of the sterilizer 200. As shown in the figure, the sterilizer 200 is provided with a cation generation unit 230 in the vicinity of one end portion of the upper surface of the base 210 covered with a resin case in a substantially rectangular shape, and the upper surface of the base 210. An anion generator 250 is installed in the vicinity of the other end.

The cation generation unit 230 is configured by accommodating a flat ceramic plate 231 in a recess formed on the upper surface of the base 210 so that the upper surface is exposed. A discharge electrode is installed on the upper side inside the ceramic plate 231 and an induction electrode is installed on the lower side. By applying a positive high voltage (for example, about 3 kV) between the two electrodes, plasma discharge is generated, Moisture (H ₂ O) in the air is ionized to generate hydrogen ions (H ⁺ ).
4H ₂ O → 2H ₂ O + O ₂ + 4H ⁺

The anion generation unit 250 is configured by installing a protection unit 253 so as to surround the needle-like electrode 251 in a U-shape. By applying a negative component high voltage (for example, about −4 kV) to the needle electrode 251, positive ions gather around the needle electrode 251 due to plasma discharge, and a large amount of electrons (e ⁻ ) from the needle electrode 251. Are released into the air. Since a large amount of electrons released into the air are very unstable, they are trapped by oxygen molecules (O ₂ ) and form superoxide anions (O ₂ ⁻ ). That is, when a high voltage of a negative component is applied to the needle electrode 251, electrons and superoxide anions are generated. At the same time, when electrons are emitted from the needle-like electrode 251, the electrons are generated from the ceramic plate 231 and combined with hydrogen ions passing around the needle-like electrode 251 to become active hydrogen (hydrogen atoms) (H).
H ⁺ + e ⁻ → H
O ₂ + e ⁻ → O ₂ ⁻

And these active hydrogen (H) and oxygen ions (O ₂ ^-) hydroperoxy radicals by bond (HOO ^-) is generated. This hydroperoxy radical (HOO ⁻ ) surrounds and attaches to positively charged biological contaminants, generates HOO-radical on the surface of biological contaminants, and causes hydrogen bonding of protein structures on the surface of biological contaminants. Destroy and destroy biological sources. The HOO-radical that reacted at the same time returns to water (H ₂ O) and returns to the air.

On the other hand, a part of the active hydrogen (H) is combined with active oxygen (OH-radical) floating in the air, and neutralizes the active oxygen (OH-radical) in the form of water molecules.
H + OH → H ₂ O

And in order to produce the said effect effectively, the air around the sterilizer 200 was made to flow in a straight line as much as possible from the cation generation unit 230 side to the anion generation unit 250 side, and was generated by the cation generation unit 230. It is necessary to reliably supply hydrogen ions (H ⁺ ) around the anion generator 250.

  FIG. 6 is a perspective view showing a state of the pair of sterilizers 200 when installed in the fan-equipped sterilizer 1. As shown in the figure, the sterilization apparatus 200 attached to the fan-equipped sterilization apparatus 1 is a pair (two units), and the bottom surfaces of the sterilization apparatuses 200 are placed in contact with each other with the anion generators 250 facing downward. . And the four sides 211 of the outer periphery which face the up-down direction of a pair of integrated sterilizer 200 are being fixed to the lower part of the front end side 81 of each wind direction board 80, as shown in FIG. As a result, the portion around the sterilizer 200 inside the inner cylinder portion 40 is divided into four spaces A1, A2, A3, A4 by the four wind direction plates 80. The cation generator 230 and the anion generator 250 of the pair of sterilizers 200 are located in the spaces A1 and A3. In addition, the upper part of the sterilizer 200 inside the inner cylinder part 40 is a space B1, and communicates with the four surrounding spaces A1, A2, A3, and A4. A fan motor 153 of the fan 140 is positioned above the space B1, and an air discharge port 149 is positioned above the four spaces A1, A2, A3, A4.

  In assembling the sterilizer 1 with a fan, first, the fan 140 is installed on the upper part of the inner cylinder part 40 of the cylindrical case part 60 to which the pair of sterilizers 200, 200 are attached, and the upper part of the outer cylinder part 20 is placed thereon. The upper case part 100 is installed so as to cover it, and screws 300 (see FIG. 1) are respectively inserted into the four screw insertion holes 131 provided in the upper case part 100 from the upper part thereof, and the screws 300 projecting from the lower ends of the projecting parts 133. Is inserted into a small hole 142 (see FIG. 4) provided in the vicinity of each corner of the pair of upper and lower flat plate portions 143, 145 of the fan 140, and the tip of the screw 300 protruding from the lower surface of the flat plate portion 145 is inserted into the cylindrical case portion. This is performed by screwing into the respective screw screw holes 93 of 60, thereby integrating the above-mentioned members. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  At this time, as shown in FIG. 4, the fan 140 has a polygonal shape (rectangular shape) when viewed from below, and a plurality (four) of outer peripheries 146 (outer peripheries of the lower flat plate portion 145). Therefore, by installing this fan 140 on the upper end side 40a of the circular inner cylinder portion 40, four opening portions of the inner cylinder portion 40 that protrude outward from the respective outer peripheries 146 of the fan 140 are generated. The air inlet 43 serves as an opening portion. That is, the air introduction port 43 is formed between the upper opening 31 of the air introduction path 30 and the outer wall 147 of the fan 140 (further, in this embodiment, between the upper opening 31 and the outer periphery 146 of the fan 140). However, the air introduced from the lower opening 33 of the air introduction path 30 is directly supplied to the discharge side of the fan 140.

  The fan-equipped sterilization apparatus 1 configured as described above, for example, rotates the suspension tool 136 so that the connector 137 faces upward and is screwed into a plug installed on the ceiling so that the fan-equipped sterilization apparatus 1 is Install. When an on / off switch installed indoors or outdoors is turned on, a power supply voltage of AC 100V is supplied to the device controller 160 through the connector 137, and the fan 140 is driven and the sterilizers 200 and 200 are simultaneously driven. When the fan 140 is driven, as shown in FIG. 7, external air is sucked from the air intake 120 and is introduced into the inner cylinder portion 40 after passing through the inside of the fan 140 (part of the blade 151). It blows out downward from the lower end surface of the cylinder part 40.

  On the other hand, in the sterilization apparatus 1 with a fan, since the air introduction path 30 and the air introduction port 43 are formed as described above, the air introduced from the lower opening 33 of the air introduction path 30 is the air of the fan 140. Without being turned to the suction port 148 side, the air is sucked by the negative pressure generated by the discharge through the air introduction port 43 and directly under the air discharge port 149 of the fan 140 and is introduced into the inner cylinder part 40. The air that has passed through the fan 140 is greatly disturbed by the propeller blades 151 and pushed downward. However, the air does not pass through the inside of the fan 140 and is near the inner peripheral surface of the inner cylinder portion 40 on the discharge side. The air that is sucked in and supplied is an air flow with little turbulence. For this reason, the outermost periphery of the downwardly turbulent air flow having a large turbulence is surrounded by the air flow having almost no turbulence supplied from the air introduction port 43, whereby the flow of the entire air flow descending in the inner cylinder portion 40. Becomes a smooth and uniform flow. Furthermore, the airflow is made more linear by the wind direction plate 80 installed in the inner cylinder portion 40. Furthermore, in this sterilization apparatus 1 with a fan, as described above, the fan motor 153 of the fan 140 is installed in the upper part of the space B1 in the upper part of the sterilization apparatus 200, 200 inside the inner cylinder part 40. Air is not blown out from the lower surface of the fan motor 153. That is, the air blown out from the ring-shaped air discharge port 149 of the fan 140 is introduced as it is into the four ring-shaped spaces A1, A2, A3, A4 formed around the sterilizer 200. Also from the point, the flow of the entire air flow descending in the inner cylinder part 40 becomes smooth.

On the other hand, as described above, the pair of sterilizers 200 and 200 are arranged such that the cation generating unit 230 and the anion generating unit 250 are linearly positioned in the vertical positions in the spaces A1 and A3 (air flow). To be consistent). At the same time, as described above, the airflows flowing in the spaces A1 to A4 are straight and smooth. For this reason, the hydrogen ions (H ⁺ ) generated by the plasma discharge of the cation generation unit 230 ride on this smooth air flow and are smoothly and reliably conveyed to the vicinity of the anion generation unit 250. In particular, in the sterilization apparatus 1 with a fan, the pair of cation generation unit 230 and the anion generation unit 250 are arranged in the separated spaces A1 and A3, and thus generated in the cation generation unit 230. Hydrogen ions (H ⁺ ) do not spread throughout the spaces A1, A2, A3, and A4, and are more reliably transported to the vicinity of each anion generator 250.

Anion generator unit 250 near the transported hydrogen ions (H ⁺⁾ is, electrons generated by plasma discharge of the needle electrode 251 (e ^-) coupled to an active hydrogen (H), and the oxygen ions generated simultaneously (O ₂ ^-) hydroperoxy radicals by binding to (HOO ^-) is generated. This hydroperoxy radical (HOO ⁻ ) rides on the air flow and is blown downward from the lower end surface of the inner cylinder portion 40. The blown out hydroperoxy radical (HOO ⁻ ) is a source of biological contaminants in the indoor air (for example, influenza virus, coronavirus, MRSA (methicillin-resistant Staphylococcus aureus), mold, Destroying powder, dung, allele substances from pets, etc.)]) effectively. At the same time, a part of the active hydrogen (H) is combined with the active oxygen floating in the air and neutralized. As described above, since the descending air flow discharged downward (in the room) from the inner cylinder portion 40 is smooth and linear, the discharged sterilized / cleaned air is efficiently distant (for example, near the floor surface). ) Can reach and efficiently circulate the air in the whole room, so that the whole room can be effectively sterilized and cleaned. At the same time, the room temperature can be made uniform.

  Further, in the case of this embodiment, the air introduction port 43 is formed only by a simple configuration in which the commercially available fan 140 having a square shape is used as it is and installed on the upper end side 40a of the inner cylinder part 40. Therefore, the air inlet 43 can be easily formed, which is preferable.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the above embodiment, the fan case 141 of the fan 140 has a quadrangular shape when viewed from below, but may be a triangular shape or a polygonal shape of a pentagonal shape or more. Various modifications can be made to the structure of the fan 140, and a mixed flow fan or the like may be used instead of the propeller type fan. Moreover, the shape and structure of the sterilizer 200 and the number of units to be installed can be variously changed. In the above embodiment, the case 10 is constituted by the two parts of the cylindrical case part 60 and the upper case part 100, but the whole may be constituted by a single-piece molded product, or the outer cylinder constituting the cylindrical case 60. The part 20 and the inner cylinder part 40 may be configured as separate parts, and the material of the case 10 may be changed to other materials (such as various metal materials and various synthetic resin materials). Further, the air intake ports 120 provided on the upper surface and the side surface of the upper case portion 100 may be provided only on the upper surface or the side surface.
