Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning indoor air, and more particularly to a method for cleaning indoor air using an aqueous solution of a natural disinfectant and bactericide (scented aqueous solution, etc.).

[0002]

2. Description of the Related Art As a method for cleaning indoor air,
Put the germicide (fragrance) solution in a water tank etc. and leave it in the room.
Examples thereof include a method for cleaning by natural evaporation of a bactericide, and a method for cleaning air by spraying in a mist with a mechanical spray device.

[0003]

In the conventional cleaning method described above, the former method waits for the bactericide to evaporate naturally before cleaning, so that the cleaning speed is slow and the cleaning is constant. Without stable cleaning is difficult.
Also, in the latter method using the spray device, the aqueous solution of the bactericide is efficiently atomized, but since the water and the bactericide components are sprayed together, the bactericide components can be separated and volatilized smoothly. It is difficult to say that the cleaning efficiency is sufficiently satisfactory because it is not performed.

The present invention has been made in view of the problems of the prior art as described above, and an object thereof is to improve the evaporation efficiency of the bactericide in the aqueous solution of the bactericide,
It is to provide a cleaning method that can expect a stable cleaning effect.

[0005]

The technical means taken by the present invention to achieve the above-mentioned object is to dissolve a natural disinfectant and sterilizer in water and drop it on the blades of a water wheel to remove the water wheel. It is characterized in that it is rotated, and an aqueous solution or emulsion of a disinfectant / sterilizing agent (a component of disinfecting / sterilizing agent in the aqueous solution) is made into a droplet by collision with a blade and is sprayed indoors.

As the above-mentioned natural disinfectant and bactericide, for example, a disinfectant bactericide containing, as an effective component, a mixture of natural hinokitiol and β-drabulin obtained by steam steaming post-treatment of Hiba waste wood produced in Aomori prefecture. However, these components are not limited to hiba wood and are contained in all wood.

[0007]

According to the above-mentioned method, the aqueous solution of the natural disinfectant and sterilizer is dropped on the blade of the water wheel to rotate the water wheel, and the rotation of the water wheel stirs the aqueous solution to disinfect the sterilizing and sterilizing components in the aqueous solution. Only chisel is sprayed. That is, the aqueous solution that becomes droplets upon collision with the blades is a component of the disinfectant / bacterial agent dissolved in water, and these are efficiently separated from the water, and as a result, the evaporation efficiency of the disinfectant / bacterial agent is improved.

[0008]

As described above, the method for cleaning indoor air according to the present invention dissolves the natural disinfectant and sterilizer in water, drops the disinfectant on the impeller of the water wheel, and rotates the water wheel to disinfect the disinfectant and sterilizer. Since the solution or emulsion is sprayed into the room by colliding with the blades, only the disinfectant disinfectant components dissolved in water are efficiently separated and sprayed in the form of a spray. The evaporation of the bactericide can be greatly improved compared to the evaporation efficiency of the conventional method in the case of natural evaporation or atomization by a spray device. Therefore, very stable cleaning can be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the cleaning method of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a cleaning apparatus, which is a water tank 1 for containing an aqueous solution a of natural disinfecting and sterilizing agents. When,
A pump 3 that sucks up the aqueous solution a in the water tank 1 and drops it on the blades 2 ′ of the water wheel 2 arranged above the water tank 1, and a gutter 4 that receives the aqueous solution a dropped on the water wheel 2 and returns it to the water tank 1. The gutter 4 is formed so as to be inclined toward the place where the drain hole 5 is formed so as to return the recovered aqueous solution a to the water tank 1. In addition to the above-mentioned configuration, the above-mentioned device has a meaning as an indoor unit (figure), and in addition to the above-mentioned configuration, the water tank 1 and the water turbine hut 7 are mounted on the table 6 containing the gutter 4.
And the illumination lamp 8 is attached. Further, the component b of the disinfectant / bactericide in the above-mentioned aqueous solution a is emulsified and dissolved in the aqueous solution as shown in FIG.

With the above construction, when the pump 3 is actuated, the aqueous solution a of the natural disinfectant and sterilizing agent in the water tank 1 is sucked up and dropped onto the blades 2'of the water wheel 2, the water wheel 2 rotates and the aqueous solution is in the form of droplets. It is scattered. As a result, the droplet-like aqueous solution is efficiently separated into the disinfecting and sterilizing agent and water, the disinfecting and sterilizing agent is efficiently evaporated, and the disinfection and sterilization of bacteria and mold are effectively performed. The components of the disinfectant / bacterial agent are efficiently evaporated by the above-mentioned operation, but the water is collected in the water tank 1 through the gutter 4. Therefore, the disinfectant / bacterial agent is regularly replenished to obtain an aqueous solution having a constant concentration. Must be kept quantitative.

Next, a comparative test of the evaporation amount when the method of the present invention is used and when it is left at room temperature will be described. The aqueous solution of natural disinfectant and bactericide used in the comparative test was prepared by dissolving 1 g of a mixture of hinokitiol and β-drabulin extracted from Hiba wood produced in Aomori prefecture in 1000 ml of water to prepare a stock solution.
An aqueous solution prepared by adding 4 parts of water to 1 part of the stock solution 30
At l, a comparison test is performed on the amount of evaporation when the water wheel is put into a water tank and the turbine is operated, and when 30 l of the water solution is put into a poly container and left to stand. The pumping flow rate when operating the water turbine shall be 4160cc per minute. The test results are shown in Tables 1 to 4 below.

As described above, as shown in Tables 1 to 4, the evaporation amount of the water turbine operation of the method of the present invention was almost double that of natural evaporation, and the remarkable effect was recognized. In addition, the disinfectant disinfectant of the Aomori prefecture hiba wood extract used for the comparative test has extremely weak toxicity, has no problem of environmental pollution, and has an advantage that it can be easily used. In addition, this drug has a broad antibacterial spectrum,
Moreover, since the MIC value against various bacteria is low, a large amount of disinfection and sterilization effect can be expected with a small amount. Furthermore, the raw material is the most abundant in all wood, and is contained in Hiba produced in Aomori prefecture. Moreover, since crystals are obtained from waste wood, they are available at extremely low cost.
