Abstract

PURPOSE:To provide an air conditioner which provides a sterilizing effect in addition to a deodorizing effect, by a method wherein a porous material to which aqueous stabilizing chlorine dioxide is adsorbed is situated in the air supply of a fan by which to circulate indoor air. CONSTITUTION:With a vent port 19 opened through control of a lever 21 during heating operation and ventilation operation, either of indoor air sucked through a suction port 6 and discharge air discharged through an outlet 5 is forced into contact with a porous material 23 in a container 18. An odor component contained in air is removed by two functions of the one being adsorbing, decomposing, absorbing, and ion-exchange function, which a ceramics material has, and the other being the deodorizing function of chlorine dioide isolated from aqueous stabilizing chlorine dioxide, and pathogenic bacteria contained in air are killed by means of chlorine dioxide. Aqueous stabilizing chlorine dioxide is dissolved in a water solution of sodium carbonate for stabilization, and for further stabilization, sodium peroxide is added, and in order to prevent chlorine dioxide from being bubbled for isolation, sodium perboric acid is added.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an air conditioner having deodorizing and sterilizing functions.

(b) Conventional technology When operating an air conditioner, the room is sealed, causing problems such as food odors, cigarette odors, sweat, rotting odors, and wall material odors. It adheres to utensils, etc. and causes odor when blowing air or heating.

For this reason, it is possible to deal with this by attaching activated carbon, etc. to the air filter as a means of deodorizing.For example, powdered activated carbon wrapped in the non-woven fabric of the filter, activated carbon
There are also proposals to use filtered fibers,
If a sufficient deodorizing (deodorizing) effect is expected, the thickness of the filter material must be increased, resulting in an increase in pressure loss, an increase in fan static pressure, and an increase in noise. It has little effect and has not been commercialized. Furthermore, whether it is in the form of powder or fiber, it is inevitable that the substance will scatter, which may impair health.

As a countermeasure to this problem, a deodorant was applied to the non-woven or woven fabric of the filter by coating or impregnating it.
It is presented in Publication No.-135059.

(C) Problems to be Solved by the Invention The deodorizing means presented in the above-mentioned publication has a problem in that when the filter is washed with water to remove dust, the deodorizing agent runs off and loses its deodorizing effect. have.

For this reason, it has been considered to knead the deodorizer into the nonwoven or woven fabric of the filter, but it is inevitable that the deodorant will not come into contact with the airflow and the deodorizing effect will be inferior.

The present invention solves these problems, and in view of the fact that mold and mites grow on heat exchangers and air filters of air conditioners, indoor wall materials, etc., and are a cause of household diseases, the present invention has deodorizing effects. The purpose of the present invention is to provide an air conditioner that also exhibits a sterilizing effect.

(d) Means for solving the problem The present invention is an air conditioner, in particular, a porous material adsorbed with aqueous stabilized chlorine dioxide is provided in the ventilation path of a fan that circulates indoor air. It is.

101,000pp J is F, D, A (equivalent to Japan's Ministry of Health and Welfare) and E in the United States.

It has been tested and inspected by P, A (environmental protection disease) and the Ministry of Agriculture, and has been certified as safe and effective in sterilization and deodorization.

For example, in the case of "pyrogen", free chlorine dioxide (C 0.0), which is effective for disinfection and deodorization, is naturally generated from a stabilizing solution when certain conditions are met. In other words, it is generated due to the loading of bacteria and malodorous components, and this condition involves the dynamic equilibrium condition of the solution containing free chlorine dioxide, and Le Chatelier's law acts to remove a large amount of free chlorine dioxide ( cfo*) is generated.

Note that this stabilizing solution does not contain or generate toxic free chlorine (CL) or hypochlorine (0(,e-)).

The physical properties of "Viologen" are shown below.

The mechanism by which chlorine dioxide (C/!OX) functions as a disinfectant is mainly an oxidation reaction, not a chlorination reaction. It has strong sterilizing power against negative bacteria, yeast, highly active filamentous fungi, and molds.

Such chlorine dioxide (COO,) is generated as follows.

That is, aqueous stabilized chlorine dioxide is chlorine dioxide (C20,
), sodium hydroxide (NaOH), and hydrogen peroxide (H.

0, ) as the main raw material, and when this stabilizing solution comes into contact with the free chlorine dioxide (CP, O) generated in the form of bubbles, it reacts alternately with the free chlorine dioxide (clot)!

occurs. While the stabilizing solution is at equilibrium and this solution is concentrated, there is only a small amount of free chlorine dioxide (Cjl!On)
However, once the concentrated solution is completely diluted, free chlorine dioxide (CQO□) is generated according to Lussiertrier's law.

Next, the mechanism by which chlorine dioxide (cj2o,) functions as a deodorant is as follows.

For example, sulfur dioxide (50 liters reacts with water and SO

The final products are chloride (C1) and R5OS-.

In addition, aqueous stabilized chlorine dioxide is chlorine dioxide (CfOX)

In addition, the porous material may be an unglazed material, but a lightweight soft ceramic material with special three-dimensional needle-like crystals manufactured by Nilgelhard in the United States has an excellent deodorizing function.
This is preferable. The fired crystals of this ceramic material are commercially available from Unique Products Co., Ltd., Kokufuda Co., Ltd., Mitsui Bussan Kakoki Hanbai Co., Ltd., and Nippon Kikai Seisakusho Co., Ltd., under trade names such as "Venus J+r Ductman J+'Ceraclin". has been done.

Malodorous components such as mercaptan (R-5H) and various solvents,
It has the function of adsorbing, decomposing and absorbing oil, etc., and exchanging ions. The reason for this adsorption and absorption function is that silicon dioxide (
While Sin has 〇-polarity and forms an anion film, silicon (Si) combines with oxygen (O) and hydrogen cations (H+) are formed in the outer shell of the combined body (crystal). This is because the crystals adhere to each other to complete the plate structure.Also, the reason why it has an ion exchange function is that the crystal is composed mainly of magnesium (Mg) atoms, and this Mg has divalent cations, making it stronger than Si. This is because it forms a 〇-polar film that combines strongly with O7, OH, H, and O at a high reaction rate.

Below, the deodorizing results of "1 Ductman" are shown as an example.

lsSH) In this way, an aqueous stabilized chlorine dioxide solution (1000 to 20000 ppm
) is sucked into a porous material with a deodorizing function and installed in the ventilation path of an air conditioner. The chlorine dioxide (CI20,) liberated from chlorine can eradicate pathogenic bacteria contained in the indoor air, and the bad odor components can be removed by the double deodorizing function of this chlorine dioxide (Cffi02) and the porous material.

When the cross flow amplifier (10) is operated during the operation of the air conditioner, the indoor air flows from the intake port (6) through the storage chamber (17> and the duct (25) in sequence). A suction air passage is formed on the leeward side of the heat exchanger (8), which is combined with the indoor air sucked in from the suction grill (3) through the heat exchanger (8) and then blown out from the air outlet (5). It is now possible to do so.

(30) is a lid provided on the lower surface of the main body (2), and a container (18a) as shown in FIG. The vent hole (19) of the container is made to face the opening (31) of the casing (12).
