Japanese Patent Laid-Open No. 2002-181358

  However, in the sterilization apparatus described above, it is effective in a use environment where fine particulate electrolyzed water mist easily reaches, that is, in a use environment where electrolyzed water mist is difficult to reach while being effective in a relatively small space, ie, large space. For example, there is a problem that it is difficult to exert its effect in kindergartens, elementary / middle / high schools, nursing care insurance facilities, hospitals, and the like. In view of this, a floor-standing air sterilization apparatus capable of eliminating the above-described problems of the conventional techniques and capable of sterilizing a large space has been developed. This sterilization device sterilizes indoor air passing through the gas-liquid contact member by blowing air in the gas-liquid contact member infiltrated with electrolyzed water, and returns the sterilized air to the room again. It is.

In such a sterilization apparatus, it is preferable that indoor air blown by the blower uniformly hits the entire gas-liquid contact member. For that purpose, it is conceivable to prepare an air blower having an air outlet equivalent to the outer shape of the gas-liquid contact member and send air. However, it is difficult to reduce the size of the sterilization apparatus for the blower having a large opening area of the air blowing port because a large installation space is required.
On the other hand, when the blower opening of the blower is made smaller than the outer shape of the gas-liquid contact member, the wind does not hit the gas-liquid contact member located outside the blower opening of the blower. In order to solve this problem, it is conceivable to provide an air guide plate that guides air from the air outlet of the blower to the entire gas-liquid contact member. However, this air guide plate may interfere with the wind sent from the blower and weaken the wind speed and the air volume.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a floor-standing type air sterilization apparatus that can ensure the wind speed and the amount of air blown from a blower.

In the present invention, the gas-liquid contact member and the blower fan are disposed in a floor-standing casing, and the electrolyzed water supply means supplies the electrolyzed water to the gas-liquid contact member, while the blower fan is in contact with the gas-liquid contact. A floor-standing air sterilization apparatus that blows indoor air toward a member, provided with a wind guide plate that guides wind from a blower outlet of the blower fan toward the gas-liquid contact member, And an extending part extending in the direction of the wind blown out by the blower fan, and a guide part inclined at the extending part toward the gas-liquid contact member located far from the outlet. And
According to this configuration, when the air blown from the blower fan passes through the extending portion, the wind speed and the amount of the blown wind can be guided to the guide portion without weakening.

In this case, the side of the gas-liquid contact member and the side of the blower fan are partitioned by a support plate, and the support plate may have an opening through which air from the opening of the blower fan passes. Good.
According to this structure, the attachment side of the blower fan and the attachment side of the gas-liquid contact member can be defined by the support plate so that the wind of the blower fan does not escape to the blower fan side.

The inclination angle of the guide part may be formed so as to be adjustable with respect to the extension part.
According to this configuration, the wind direction can be changed according to the shape, size, and mounting position of the gas-liquid contact member.

Furthermore, the length of the extension part may be formed to be adjustable.
According to this configuration, the extending portion can be adjusted to a length that does not cause turbulence or vortices in the flow of air blown from the blower fan.

According to the present invention, once the wind from the blower fan is guided by the extending portion of the wind guide plate, the wind speed and the volume of the wind blown from the blower without causing turbulent flow or vortex in the wind flow. Can be secured as it is. Further, the air can be applied almost uniformly onto the gas-liquid contact member by sending the room air to the gas-liquid contact member located far from the outlet of the blower fan by the guide portion.
Further, by providing the partition plate, it is possible to prevent the wind of the blower fan from escaping to the blower fan side. As a result, the amount of wind sent to the gas-liquid contact member can be increased.
Furthermore, by changing the inclination angle of the guide portion, the wind direction can be changed according to the size and position of the gas-liquid contact member. Therefore, indoor air can be uniformly applied to the entire gas-liquid contact member.
Furthermore, by adjusting the length of the extending portion, it is possible to prevent turbulence and vortices from being generated in the wind flow. Therefore, the wind volume and speed are not reduced.

Hereinafter, a floor-standing type air sterilization apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of a floor-standing air sterilizer according to an embodiment of the present invention. In the following description, the up / down, left / right, and front / rear directions indicate directions in the state of FIG.
In FIG. 1, the code | symbol 1 shows a floor-standing type air sanitizer. This floor-mounted air sterilization apparatus 1 includes a box-shaped housing 2, which includes a leg piece 2A, a front panel 2B, and a top panel 2C, on both sides of the top panel 2C. The operation lid 2D and the opening / closing lid 2E are arranged side by side.

FIG. 2 shows a state in which the front panel 2B and the top panel 2C of the floor-standing air sanitizer shown in FIG. 1 are removed. The interior of the housing 2 is defined in three rooms 41a, 41b, 41c by two partition plates 40a, 40b extending in the vertical direction. A control board or the like (not shown) is accommodated in the electrical equipment chamber 41a located on the left side. The water supply chamber 41b located on the right side stores a detachable water supply tank 11, a detachable support tray 10 for storing drainage, and the like.
FIG. 3 is a side cross-sectional view showing a state of being cut up and down at the center of FIG. In the sterilization chamber 41c located in the center, as shown in FIGS. 2 and 3, a horizontally long suction port 3 is formed in the lower portion, and a prefilter 3A is disposed above the suction port 3. A blower fan 7 is disposed above the pre-filter 3A, and a gas-liquid contact member 5 having high water retention is disposed above the blower fan 7 in a brace shape as shown in FIG. A horizontally long air outlet 4 is disposed above the liquid contact member 5.

  As shown in FIGS. 2 and 3, the sterilization chamber 41 c of the housing 2 is attached with a support plate 8 having a substantially horizontal plane at the center in the vertical direction. A fan 7 is attached. In the plane of the support plate 8, an opening 8 a penetrating in the vertical direction is formed at the center position in the left-right direction of the gas-liquid contact member 5 (see FIG. 4). The opening 8a is provided with an air blowing port 7a of the blower fan 7 facing upward, and the air blown from the blower fan 7 is blown upward. The shape of the opening 8a and the blower opening 7a of the blower fan 7 are substantially equal and the size is also equal. Moreover, each opening area of the ventilation port 7a and opening part 8a of a ventilation fan is an area smaller than the horizontal projection area of the gas-liquid contact member 5 above this opening part 8a.

  FIG. 4 is a state in which the floor-standing air sanitizer 1 shown in FIG. 2 is viewed from the rear side, and shows an enlarged portion of the opening 8a. As shown in FIGS. 3 and 4, a pair of air guide plates 50 are provided in the opening 8 a of the support plate 8 symmetrically on the upper portion of the opening 8 a. The lower end of the air guide plate 50 is fixed to the support plate 8. The air guide plate 50 extends from the lower end portion upward and the gas-liquid contact extending from the upper end portion of the extension portion 50a and located far from the air blowing port 7a of the blower fan 7. It is comprised with the guide part 50b which inclines to the member 5 diagonally upward. The extension part 50a and the guide part 50b of the air guide plate 50 are integrally formed by bending a sheet metal.

  On the other hand, the gas-liquid contact member 5 described above is a filter member having a honeycomb structure, and has a structure in which a wide gas contact area is secured, electrolytic water can be dripped, and clogging is difficult. That is, as shown in FIG. 5, the gas-liquid contact member 5 is formed in a honeycomb shape as a whole by joining a corrugated material 5A and a flat material 5B. These materials 5A and 5B include materials that are less reactive to electrolyzed water, which will be described later, that is, materials that are less susceptible to degradation by electrolyzed water, such as polyolefin resin-based, PET resin-based, vinyl chloride resin-based, fluororesin-based, or ceramic resin. Materials such as systems are used. The inclination angle θ of the gas-liquid contact member 5 is desirably 30 ° or more. In the case of less than that, the dropped electrolyzed water does not flow along the inclination of the gas-liquid contact member 5 but falls downward. Further, when the inclination angle θ approaches 90 °, the air blowing path passing through the gas-liquid contact member 5 becomes nearly horizontal, and it is difficult to blow upward by that much. When this blowing direction is horizontal, the blown air cannot be blown far away, and as described later, the device is not suitable for sterilization of a large space. The inclination angle θ is preferably 80 °> θ> 30 °, and is about 40 ° in the present configuration.

6A to 6C show means for dropping electrolytic water onto the gas-liquid contact member 5.
A water tray 9 (see FIG. 3) is disposed below the gas-liquid contact member 5, and a support tray for storing water flowing in from the water tray 9 below the downstream portion of the water tray 9. 10 is disposed. The support tray 10 is provided with a water supply tank 11 for supplying water containing chlorine ions into the support tray 10 and a circulation pump 13. An electrolytic tank 31 is connected to the circulation pump 13, and an electrolytic water supply pipe 17 is connected to the electrolytic tank 31. The electrolyzed water supply pipe 17 is configured to include a large number of water spray holes (not shown) on the outer periphery, and as shown in FIG. 6B, in the water spray box 5C formed at the upper edge of the gas-liquid contact member 5. Has been inserted.

  As shown in FIG. 6C, the electrolytic cell 31 includes electrodes 32 and 33. When the electrodes 32 and 33 are energized, the water flowing into the electrolytic cell 31 is electrolyzed to generate active oxygen species. Here, the reactive oxygen species are oxygen having higher oxidation activity than normal oxygen and related substances, such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide, in a narrow sense. It is assumed that active oxygen includes active oxygen in a broad sense such as ozone and hypohalogen acid. The electrolytic cell 31 is arranged close to the gas-liquid contact member 5 and is configured to be able to immediately supply the active oxygen species generated by electrolyzing water to the gas-liquid contact member 5.

The electrodes 32 and 33 are, for example, electrode plates in which the base is made of Ti (titanium) and the coating layer is made of Ir (iridium) or Pt (platinum). The current value applied to the electrodes 32 and 33 is the current density. A predetermined free residual chlorine concentration (for example, 1 mg (milligram) / l (liter)) is generated as several mA (milliampere) / cm ² (square centimeter) to several tens of mA / cm ² .

When water is passed through the electrodes 32 and 33, the cathode electrode
4H ⁺ + 4e ⁻ + (4OH ⁻ ) → 2H ₂ + (4OH ⁻ )
And the anode electrode
2H ₂ O → 4H ⁺ + O ₂ + 4e ⁻
As soon as the reaction of
Chlorine ions contained in water (pre-added to water)
2Cl ⁻ → Cl ₂ + 2e ⁻
In addition, this Cl ₂ reacts with water,
Cl ₂ + H ₂ O → HClO + HCl
It becomes.

  In this configuration, when the electrodes 32 and 33 are energized, HClO (hypochlorous acid) having a high sterilizing power is generated, and air is passed through the gas-liquid contact member 5 to which this hypochlorous acid is supplied. The gas-liquid contact member 5 can prevent germs from breeding, and can inactivate viruses floating in the air passing through the gas-liquid contact member 5. Further, when the odor passes through the gas-liquid contact member 5, it reacts with hypochlorous acid in the electrolytic water, and is ionized and dissolved to be removed from the air and deodorized.

Next, the operation of the floor-standing air sterilizer according to the embodiment of the present invention will be described.
The wind blown upward from the blower opening 7 a of the blower fan 7 is further blown upward from the opening 8 a of the support plate 8 and is guided upward along the extending portion 50 a of the wind guide plate 50. At this time, the wind blown along the extension 50a is guided upward without causing turbulence or vortex in the flow and without reducing the wind speed and the air volume.
The wind guided by the extending portion 50a is then guided toward the gas-liquid contact member 5 located far from the blower opening 7a of the blower fan 7 along the inclination of the guide portion 50b.

Next, the experimental result which confirmed the effect of the baffle plate 50 is demonstrated.
When air is blown from the blower fan 7 at a wind speed of about 3.5 m / s to 3.8 m / s without providing the air guide plate 50, the gas-liquid contact member 5 located outside the blower port 7 a of the blower fan 7 is used. The wind speed was about 0.3 m / s to 0.4 m / sec.
Next, when air is blown from the blower fan 7 at a wind speed of about 3.5 m / s to 3.8 m / sec without providing the extending portion 50 a on the air guide plate 50, the blower fan 7 is placed outside the blower port 7 a. The wind speed at the gas-liquid contact member 5 positioned was 1 m / sec or less.
On the other hand, when the extension part 50a is provided in the air guide plate 50 and the air is blown from the blower fan 7 at a wind speed of about 3.5 m / s to 3.8 m / sec, the air blower plate 7 is provided outside the blower port 7a. The wind speed at the gas-liquid contact member 5 positioned was a value exceeding 1 m / sec. Moreover, the wind speed in the center part which does not remove | deviate from the opening part 7a of the ventilation fan 7 remained about 3.5 m / s-3.8 m / sec.

  According to the floor-type air sterilization apparatus according to the embodiment of the present invention, by guiding the wind blown upward from the blower port 7a of the blower fan 7 toward the gas-liquid contact member 5, Without causing turbulent flow or vortices in the wind flow, it is possible to ensure the wind speed and volume of the wind blown from the blower 7. Moreover, by providing the guide part 50b, wind can be sent toward the gas-liquid contact member 5 located far from the air blowing port 7a of the air blowing fan 7.

The best mode for carrying out the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. .
In the present embodiment, the extended portion 50a and the guide portion 50b of the air guide plate 50 are integrally formed. However, each of them is configured as a separate part and is detachably formed with screws or the like, and guides having different inclination angles. The inclination angle of the air guide plate 50 can be freely adjusted by preparing and selecting a plurality of the parts 50b. Thereby, the direction of the wind sent to the gas-liquid contact member 5 can be adjusted.
Further, the length of the extending portion 50a in the vertical direction may be extended by sliding the position of the guide portion 50b in the vertical direction. Thereby, the direction of the wind sent to the gas-liquid contact member 5 can be adjusted.
