Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance storage crate with a deodorizing function in which a odor component is deodorized in a clog box placed at the entrance, and a deodorant material for the entrance storage clog box used therein. .

[0002]

2. Description of the Related Art In general, in a clog box such as a crate box for storing an entrance, a box serving as a clog box body is usually covered with an opening door or a sliding door. It is a structure that hides it so that it cannot be seen. The air in the box stays in the box and is filled with moisture and odor generated from stored items such as shoes and umbrellas.

[0003] The odor generated in shoes is due to sweat and secretions released from feet soaked in shoes and socks, and lower fatty acids (mainly butyric acid / isovaleric acid) formed by decomposition by fungi and various bacteria. These lower fatty acids have a very unpleasant odor, even in trace amounts, and stimulate human odor.

[0004] Originally, the entrance of a house is the part that corresponds to the face of the home, but since the smell can no longer be felt, visitors may feel strongly even if they do not feel it, and family members may feel it. May complain. In particular, there is a problem that children's shoes are easy to get dirty, and they are not often washed disposable and are often left between the porches, so that the odor of the children's shoes often fills the entrance space. .

[0005] In the case of the shoe crate, when shoes that are wet immediately after use or shoes that are wet in rain are put in, moisture is brought into the box and the humidity inside the box increases. For this reason, shoes immediately after use cannot be stored immediately, and can only be stored in the porch after waiting for air to dry (usually about 6 hours or more). Often the shoes are scattered and do not clear up.

In addition, since the inside of the box is sealed, the humidity becomes higher than the outside, and the air stays and stagnation occurs. for that reason,
If the shoes are not used frequently, molds may be generated, bacteria may be propagated, and the stored items may be damaged, or an odor may be generated.

In order to allow shoes wet with rain to be put in a shoe box, there is also provided one provided with a drying chamber for generating hot air and forcibly drying the shoes. In this case, the cost is high, and drying suitable for individual items cannot be selected. In addition, forced drying with hot air rather damages shoes or generates an odor during heating. Further, there is a type in which heated air is circulated in a clog box, but there is the same problem as described above.

Activated carbon, ZnO and the like are generally used as deodorizing materials for deodorizing malodors, but they are not so effective in deodorizing lower fatty acids emitted from shoes and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has as its object to provide a door storage crate with a deodorizing function which can adsorb a lower fatty acid which is a malodorous component and can deodorize and can be used comfortably. It is an object of the present invention to provide a deodorant material for entrance clogs that can efficiently adsorb lower fatty acids present in a gas with a high adsorption capacity.

[0010]

According to a first aspect of the present invention, there is provided an entrance storage crate with a deodorant function, which is a storage member for storing shoes, umbrellas and the like placed at the entrance. Characterized in that a function of adsorbing lower fatty acids, which are malodorous components generated specifically, and deodorizing them is provided. The lower fatty acid, which is a malodorous component in the shoe box, can be effectively adsorbed and deodorized, and even those installed at the entrance can be used comfortably.

According to a second aspect of the present invention, there is provided an entrance storage crate with a deodorizing function according to the first aspect, wherein one of the clog boxes is provided with an intake hole for taking in outside air into the clog box, and the other of the clog box is provided. An exhaust hole is provided to exhaust the air in the clog box, and the outside air is sucked into the clog box through the intake hole, thereby extinguishing the exhaust air from the exhaust hole while replacing the dirty air in the clog box with clean air outside. A deodorizing device is provided to deodorize using odor material so as not to leave odor in exhaust air.
When the deodorizer is activated, the outside air is sucked into the clog box through the intake port, and the dirty air in the clog box is replaced with the clean air outside, exhausted from the exhaust port and deodorized when exhausted from the exhaust port. The lower fatty acid is effectively adsorbed and deodorized by the deodorizing material of the device so that no odor remains in the exhaust air. By doing so, the drying of the shoes is promoted due to the occurrence of wind in the clog box, the relative humidity in the clog box is reduced, and the generated odor is carried away by the deodorant material.
In addition, since the inside of the clog box is low in humidity and the stagnation of air is eliminated, the growth of mold and germs can be suppressed.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 and 2, a clog box 1 is installed so as to extend between a rising frame 3 of an entrance 2 and a porch 4 between entrances. Geta box 1
Is supported. The inside of the clog box 1 is divided into a plurality of storage spaces 6 by a partition 15, and a shelf 7 and the like are provided in each storage space 6. A door 8 is provided at the front opening of the clog box 1 so as to be openable and closable, and a packing 9 is attached to the front opening of the clog box 1 to keep airtight when the door 8 is closed. An intake hole 10 for taking in outside air is provided on one side of the clog box 1, and an exhaust hole 11 for exhausting the air inside the clog box 1 is provided on the other side of the clog box 1. In the case of this example, the shoe box 1 is provided with an intake hole 10 and an exhaust hole 11 in the lower wheel 12 portion. Further, a ventilation hole 16 for communicating the adjacent storage space 6 is formed in the partition 15 in the clog box 1.

The suction hole 10 is provided with a moisture absorbing layer filter 13 for dehumidifying the air sucked into the clog box 1. A deodorizing device 14 is mounted below the exhaust hole 11 so as to communicate with the exhaust hole 11. The deodorizing device 14 includes a blower fan for blowing air for exhausting and contains a deodorizing material that adsorbs lower fatty acids (butyric acid, isovaleric acid, etc.).

When the deodorizing device 14 is operated, the outside air is sucked into the shoe box 1 through the air inlet 10 and the air is sucked into the shoe box 1 as shown in FIGS.
When the air flows into the clog box 1 as shown by the arrow, the dirty air in the clog box 1 is exhausted from the exhaust hole 11 while replacing the clean air outside, and the deodorizing device is exhausted from the exhaust hole 11. The lower fatty acids are effectively adsorbed and deodorized by the fourteen deodorizing materials so that no odor is left in the exhaust air. By doing so, the drying of the shoes is promoted due to the occurrence of wind in the clog box 1, the relative humidity in the clog box 1 is reduced, and the generated odor is carried away by the deodorant material. In addition, since the inside of the clog box 1 is low in humidity and the stagnation of air is eliminated, the growth of mold and various germs can be suppressed. Furthermore, the inside temperature of the clog box 1 is 7 due to the ventilation.
0% or less (it becomes even lower if the humidity of the outside air is low), and the humidity (4
(0% to 70%), and even leather shoes that have been stored for a long time will not mold and will not give off an odor. By ventilating, even if you put in something wet immediately after wearing it, it can be dried as much as or more than if you leave it in the porch 4 and after about 6 hours (storing it at night, next morning) It is in a state where it can be put on comfortably. In addition, the shoes are not damaged because of natural and natural drying. In addition, since the deodorant is deodorized with a deodorant material that adsorbs lower fatty acids, the smell in the shoe box 1 is less likely to occur, for example, as follows.

Odor intensity 2.5 (how much odor you can tell) →
Odor intensity of 1 or less (at least an odor can be perceived) As described above, the deodorizing device 14 is provided with a deodorant material for a crate box at the entrance to adsorb lower fatty acids present in the gas. A material selected from at least one of hydroxides such as magnesium hydroxide, calcium hydroxide, and zirconium hydroxide is used as the material. By using the deodorant material of such a substance, the malodor of the lower fatty acid which could not be deodorized by the conventional deodorant material can be deodorized with high efficiency.

At this time, it is desirable to give the deodorant material a shape such as a pellet or a honeycomb, so that the adsorption capacity of the malodorous component can be increased and the deodorant function can be maintained for a long time.

[0019]

EXAMPLES Hereinafter, the above deodorizing material will be described in more detail with reference to examples. (Example 1) A metal chloride, a metal oxide (including ZnO) and a powder of the hydroxide were prepared as deodorizing agents, and 0.2 g of each powder was placed in a 1-liter Erlenmeyer flask and uniformly placed on the bottom of the flask. Spray. Further, a small bottle with filter paper inserted is prepared and inserted into each flask. Butyric acid 1
After the 0 wt% aqueous solution is attached to the filter paper in the flask by a microsyringe by 50 μl each, the flask is sealed. At the same time, a sample in which butyric acid was similarly adhered to a flask containing no deodorant was prepared as a comparative object, and this was used as a blank. And after a certain time (here 30 minutes)
The residual gas concentration was measured using a gas detector tube, and the removal rate was determined by the following equation.

Removal rate (%) = (gas concentration after 1 to 30 minutes) / (gas concentration after 30 minutes of blank) × 100 (Example 2) Isovaleric acid which is the same lower fatty acid as butyric acid , The removal rate was determined in the same procedure as in Example 1.

Table 1 shows a list of the evaluation of lower fatty acid removal in Examples 1 and 2.

[0022]

[Table 1]

As can be seen from the results in Table 1, it can be said that the hydroxide (← mark) of the present invention has a higher adsorption effect on lower fatty acids than zinc oxide (（mark). (Example 3) After mixing zirconium hydroxide with the composition shown in Table 2 below, the mixture was kneaded with water to form a clay. Next, this clay-like material was extruded into a honeycomb shape, press-molded, and dried by heating to prepare a zirconium honeycomb. Similarly, an activated carbon honeycomb was prepared.

[0024]

[Table 2]

Using the zirconium honeycomb and the activated carbon honeycomb described above, butyric acid adsorption performance was measured by an experimental apparatus as shown in FIG. In FIG. 3, A is a butyric acid gas generator for generating butyric acid gas at a constant concentration, B is a gas flow direction, C is an IN side concentration measuring unit for measuring the IN side gas concentration, and D is the OUT side gas concentration. The OUT-side concentration measuring unit for measurement, E is a material honeycomb setting unit for setting a zirconium honeycomb or an activated carbon honeycomb. Using this experimental apparatus, butyric acid is continuously generated in a butyric acid gas generator A, butyric acid gas is passed through a predetermined area of each honeycomb, and the gas concentration before passing through the honeycomb and the butyric acid gas concentration after passing through the honeycomb are measured. The measurement was performed in the IN-side concentration measuring section C and the OUT-side concentration measuring section D using a gas detection tube. The measurement results are shown in Table 3 (measurement results of one pass of butyric acid of each honeycomb).

[0026]

[Table 3]

From the above results, it can be seen that the honeycomb using zirconium hydroxide exhibits a longer removal performance and a larger adsorption capacity than the honeycomb using activated carbon.

[0028]

According to the first aspect of the present invention, in a shoe box which is a storage member for storing shoes, umbrellas and the like placed at the entrance, a lower fatty acid, which is a malodorous component generated uniquely, is absorbed and erased. Because of the odor function, lower fatty acids, which are malodorous components in the clog box, can be effectively adsorbed and deodorized, so that even those installed at the entrance can be used comfortably.

[0029] The invention of claim 2 of the present invention relates to claim 1
In one of the clog boxes, an intake hole for taking in the outside air into the clog box is provided, and on the other side of the clog box, an exhaust hole for exhausting the air in the clog box is provided, and the outside air is sucked into the clog box from the intake hole. By replacing the dirty air in the clog box with the outside clean air by exhausting from the exhaust hole, a deodorizing device was used to deodorize using deodorant material and leave no odor in the exhaust air. When the deodorizing device is operated, the outside air is sucked into the clog box through the suction hole, and the dirty air in the clog box is replaced with the clean air outside, and the air is exhausted from the exhaust hole and exhausted from the exhaust hole. The deodorizing material of the deodorizer is used to effectively adsorb lower fatty acids and deodorize them so that no odor is left in the exhaust air. Is promoted, and the relative humidity in the Odor also those carried away deodorizing material, also by the inside cupboard low humidity, by the accumulation of air disappears, in which fungi, bacteria breeding is suppressed.

A third aspect of the present invention is a clog box, which is a storage member for storing shoes, umbrellas, and the like placed at the entrance, adsorbing lower fatty acids, which are malodorous components generated uniquely, at the entrance. Since it is a box deodorant material and uses a substance selected from at least one of hydroxides such as magnesium hydroxide, calcium hydroxide and zirconium hydroxide in order to adsorb lower fatty acids present in the gas, It is possible to effectively remove the unpleasant odor generated in the shoe box and realize a comfortable living space.

The invention of claim 4 of the present invention provides the method of claim 3
In the above, since the shape of a substance such as a pellet or a honeycomb is imparted to the substance that adsorbs the lower fatty acid, the adsorption capacity of the malodorous component can be increased and the deodorizing function can be maintained for a long time.
