Abstract

PURPOSE:To prevent the deterioration of the deodorizing capacity and to contrive the maintenance-free by bringing an ascorbic acid solution into contact with a filter consisting of expanded iron, and also, allowing air to pass through the filter. CONSTITUTION:In a housing 1 in which a vent port is formed in the front and the back, a fan 2 is installed, and also, expanded iron 3 is provided in a shape of intersecting a vent line part. Also, as for the expanded iron 3, its lower part is immersed in an immersed layer 6 in which an ascorbic acid solution 5 collects. Accordingly, the ascorbic acid solution soaks into the whole the expanded iron 3, by a capillary phenomenon, and when ventilation is executed by rotating the fan 2, a temperature of air falls by about 5 deg.C by heat of vaporization at the time when the ascorbic acid solution is vaporized and cold air is discharged from a discharge port in from of the housing 1. Also, the expanded iron 3 eliminates a bad-smelling component contained in air passing through the inside of the housing 1 and deodorization is executed, and also, the deodorizing capacity which the expanded iron 3 has can be reproduced by aqueous vapor at the time when the ascorbic acid solution is vaporized, and deterioration of the deodorizing capacity of the expanded iron 3 is eliminated.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a deodorizer that removes odors from indoors or small spaces.

[Conventional technology]

Conventionally, deodorizers that use activated carbon as a filter have been used.

[Problem to be solved by the invention]

However, since the deodorizing ability of this filter quickly decreases, the filter must be replaced frequently. The present invention has been made in view of these points, and its purpose is to provide a deodorizer that requires almost no maintenance.

[Means to solve the problem]

The deodorizer of the present invention is characterized by comprising a filter made of foamed iron, contact means for contacting the filter with a 7-scorbic acid solution, and a fan for passing air through the filter. . [Function] According to the present invention, high deodorizing ability is obtained by foamed iron, and since the deodorizing ability of this foamed iron is regenerated by aeration and contact with an ascorbic acid solution, the deodorizing ability does not decrease. There are almost no such things. In addition, foamed iron is an iron-based porous material and a metal complex whose surface has been treated with chemicals. For example, iron powder is applied to urethane foam and then heat treated to form a three-dimensional mesh of iron. A reaction product obtained by forming a sintered porous body and immersing it in an ascorbic acid solution to generate an iron-ascorbic acid reaction product on the surface layer of the skeleton of the porous body and iron. It is a porous material that coexists, and a) It chemically and physically deodorizes the bad odors and harmful components of most everyday odors (nitrogen, sulfur, exhaust gas, etc.) (metal ions). and gas adsorption reactions by metal complexes, 2
(By detoxification of gas through oxidation-reduction reaction when low iron is converted to low iron, catalytic decomposition of adsorbed gas by metal oxide, etc.) b) C Ventilation which does not re-release odor as it is deodorized through catalytic chemical reaction. It has a long lifespan because its functions can be regenerated.d The regeneration ability increases when it comes into contact with water vapor or heat.e Since it is iron-based, it is an electrical conductor and has the characteristics of not burning. [Example] The present invention will be described in detail based on the illustrated example below.
Figures 3 to 3 show an example in which the fan is used as a cooling fan. A fan 2 is installed inside a housing 1 that has vents formed on the front and back sides, and a foamed iron 3 is used to ventilate the fan. It is arranged to cross the road section. In the armpit, the foamed iron 3 here has its lower end placed in a dipping tank 6 that collects an ascorbic acid solution 5 supplied from a water tank 4, and its lower end is immersed in the ascorbic acid solution 5. Therefore, the ascorbic acid solution is permeated throughout the foamed iron 3 due to capillary action. Therefore, when the fan 2 is rotated to blow air, the ascorbic acid solution that has permeated into the foamed iron 3 is vaporized. The temperature of the air decreases by 5° C. due to the heat of vaporization during this process, and therefore cold air is discharged from the discharge port on the front surface of the housing 1. In addition, the foamed iron 3 is deodorized to remove odor components contained in the air passing through the housing 1, and the water vapor produced when the ascorbic acid solution is vaporized is due to the deodorizing ability of the foamed iron 3. In addition, since the iron foam 3 is constantly supplied with ascorbic acid, the deodorizing ability of the iron foam 3 does not deteriorate in this respect as well. Figures 4 and 5 show food storage using the above-mentioned cooling fan, which removes odors and lowers temperature by circulating air. 8 in Figure 0 shows the external casing. , 9 is the food shelf 6 food l! If 19 is made of foamed iron, the deodorizing effect will be even higher. [Effects of the Invention] As described above, in the present invention, not only is a high deodorizing ability achieved by the foamed iron, but also the deodorizing ability of the foamed iron is regenerated through aeration and contact with an ascorbic acid solution.
The deodorizing ability hardly decreases, and high deodorizing ability can be obtained over a long period of time without maintenance.
