[0005]

However, in such a locker, the air blown from the air outlet is odorless and harmless, and it is safe because ozone harmful to the human body is not blown out. However, since the reaction between the odorous component and ozone is carried out only in the airflow duct 02, it takes a long time to deodorize and sterilize the locker, and temporarily the air in the locker is deodorized and sterilized. Even if it is done, deodorize clothes etc. stored in the locker directly,
It could not be sterilized.

The present invention has been made by paying attention to such problems, and it is possible to efficiently deodorize and sterilize in a storage unit such as a locker in a short time, and directly deodorize clothes stored in the storage unit. The object of the present invention is to provide a deodorizing device such as a locker that can be sterilized.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, 1 in FIG. 1 is a locker equipped with the deodorizing device of the embodiment of the present invention, and 2 is inside the locker 1. The formed storage parts 3 respectively represent the clothes suspended by the hanging bar 4 which is laid across the inside of the storage part 2. As shown in FIGS. 1 and 2, the storage part 2 is covered by both side plates 1a, 1a of the rocker 1, upper partition plates 5a, 6a, and a rear plate 7, and the front surface thereof. Can be opened and closed by a door 8 pivotally attached to the front ends of the side plates 1a, 1a.

The rear plate 7 has a plurality of air outlets 9 which will be described later, and the back plate 1 of the rocker 1.
The rear plate 7 is arranged at a position slightly ahead of the back plate 1b so that a predetermined space S is formed between the rear plate 1b and the rear plate 1b.

An upper compartment 5 is formed above the upper compartment 5a, and a first airflow duct 10 is formed in the upper compartment 5.
And a control device 1 having a control panel 11 on the front surface
2 and 2 are installed internally.

A fan 14 driven by a motor 13 and an ozone generator 15 for supplying ozone are arranged in the first air flow duct 10, and the ozone generator 15 is provided in the upper partition plate 5a. The first airflow duct 10 is connected to the upper surface of an air intake port 16 formed in the front, and one end of the first airflow duct 10 is connected to a communication port 17 formed in the rear of the upper partition plate 5a. Therefore, when the fan 14 is operated, the air in the storage unit 2 is transferred to the first through the suction port 16.
The air is sucked into the air flow duct, further passes through the ozone generator 15, and is discharged into the space S.

Further, the first airflow duct 10 is formed in a tapered shape so that its cross section becomes wider toward the rear, as shown in FIG. 4, and its rear end has a maximum opening. The cross-sectional area of the communication port 17 located at the rear end is larger than the cross-sectional area of the suction port 16 and the first airflow duct 10 in the vicinity thereof. Therefore, the flow velocity of the air sucked by the operation of the fan 14 and passing through the ozone generator 15 is gradually reduced after passing through the ozone generator 15.

Further, the horizontal cross-sectional area of the space S is 3 to 5 times or more the cross-sectional area of the communication port 17, and the flow velocity of the air discharged from the communication port 17 into the space S is Rapidly decreases due to the chamber effect in the space S
Inside, the pressure is almost uniform. Therefore, even if air is introduced from the upper portion of the space S, approximately the same amount of air is always blown into the storage portion 2 from the respective air outlets 9 formed above or below the rear plate 7. It is like this.

A lower compartment 6 is formed below the lower compartment plate 6a. Inside the lower compartment 6, an ozone decomposing device 19 having a catalyst for decomposing unreacted ozone therein and a motor 20 are driven. A second airflow duct 18 having a fan 21 is installed. In this embodiment, activated carbon or the like is used as the catalyst.

A plurality of inlets 22 and outlets 23 are formed in the left-right direction at the front and rear positions of the lower partition plate 6a (see FIGS. 1 and 5). These inlets 22 and outlets 23 are provided. The front and rear end face openings of the second air flow duct 18 are respectively connected to the lower surfaces of the.

Also in the second airflow duct 18, if the cross-sectional area of the duct near the blow-out port 23 is made larger than the cross-sectional area of the duct near the fan 21 and the catalyst 19, a plurality of ducts are formed in the left-right direction. Air can be uniformly blown out from each of the punched air outlets 23 by the chamber effect.

Further, as shown in FIG. 6, the upper surface of the air outlet 23 and the air inlet 22 formed in the lower partition plate 6a is covered with a cover body 24 having a substantially dome shape, and the air is Inhalation through the opening 24a formed on the side surface,
It is supposed to be blown out. By doing this,
Even if articles or the like are appropriately placed on the lower partition plate 6a while the storage part 2 is being used, or clothes that have been suspended are dropped and the upper surfaces of the suction port 22 and the air outlet 23 are blocked. , A communication passage for air is secured.

Therefore, the suction port 22 is used while the storage section 2 is in use.
Alternatively, the outlet 23 is inadvertently blocked and air is not circulated in the second airflow duct 18, and the ozone decomposing function does not work, and the ozone concentration in the storage section 2 rises too much.
There is no fear of disturbing the fan 21.

Further, as shown in FIG. 7, if a groove portion 25 having an appropriate width is provided on the lower partition plate 6a and an intake port 22 and an outlet port 23 are bored on the inner bottom surface of the groove portion 25, the lower partition chamber can be formed. Since a predetermined gap is formed between the lower surface of the article placed on 6a and the bottom surface of the groove portion 25, and this gap functions as an air communication passage, the same effect as described above can be obtained.

Hereinafter, a deodorizing and sterilizing method in the storage part 2 of the locker 1 thus constructed and its operation will be described.
First, as components that cause an odor in the storage unit 2, hydrogen sulfide, methyl mercaptan, dimethyl sulfide,
Ammonia, carboxylic acid, etc. are considered, and these components are
Most of the substances except the carboxylic acid are oxidatively decomposed by ozone and converted into odorless substances.

In the locker 1 according to the embodiment of the present invention, the air in the storage section 2 is driven by the motor 13 by the fan 1
The air sucked into the first airflow duct 10 by the suction port 4 through the suction port 16 is generated by the ozone generator 1 as shown in FIG.
After passing through 5, the gas is discharged into the space S, and then is discharged again into the storage section 2 through the air outlet 9. Then, as the fan 14 is driven, the ozone generator 15 is activated and an appropriate amount of ozone is supplied.

Therefore, the odor sucked into the first airflow duct 10 is oxidized and decomposed by the ozone supplied by the ozone generator 15 while passing through the ozone generator 15, and becomes odorless air to be stored in the storage portion. It is discharged into 2. The air in the storage section 2 is purified by repeating the circulation of the air in the storage section 2 as described above.

Further, not all ozone supplied from the ozone generator 15 reacts with the odorous components, but most of the ozone is blown out into the accommodating portion 2 in an unreacted state.
Therefore, the ozone concentration in the storage unit 2 is rapidly increased, so that not only the odorous components contained in the air but also the odorous components attached to the clothes 3 are decomposed by the ozone. Therefore, it is possible to efficiently deodorize and sterilize the air in the storage part 2 and the stored clothes 3 and the like in a short time.

At the same time, the air in the storage unit 2 is
A fan 21 driven by 0 is sucked into the second airflow duct 18 through the suction port 22.
Then, the unreacted ozone in the storage unit 2 is decomposed when passing through the ozone decomposing device 19, becomes harmless oxygen, and is discharged into the storage unit 2 from the outlet 23. Therefore, the ozone concentration in the storage unit 2 is lowered.

The fan 1 of such a first air flow duct 10
The ozone generator 4 and the ozone generator 15 have a normal controller 12 for the fan 21 of the second air flow duct 18 and the ozone decomposer 19.
Thus, when one of them is in the operating state, the other is in the stopped state, and this can be repeated for an appropriate time.

Further, especially when the user wants to rapidly perform deodorization, sterilization, etc., the ozone concentration in the storage section 2 can be rapidly increased by adjusting an appropriate adjustment knob 26 provided on the control panel 11, for example. , Can be lowered.

As described above, in the deodorizing device such as the locker according to the embodiment of the present invention, the ozone supplied by the ozone generator 15 remains unreacted with other odorous components in the storage portion. Since it is blown into the container 2, the ozone concentration in the storage part 2 can be rapidly increased, the odor can be decomposed and purified in a short time, and the components of the odor adhering to clothes and the like can be oxidized. . When it is desired to reduce the ozone concentration, the fan 21 of the second airflow duct 18 is operated to rapidly reduce the unreacted ozone concentration.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions within the scope not departing from the gist of the present invention, the present invention is not limited. Included in the invention.

For example, the outlets 9 and 23 and the suction port 16,
The shapes such as 22 are not limited to those of the embodiment, but can be variously modified.
