Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for accommodating a white robe, work clothes, shoes, slippers, medical and barber-related equipment and the like for disinfecting and deodorizing and drying.

[0002]

2. Description of the Related Art In food factories, hospitals, etc., it is necessary to hygienically keep white coats and work clothes. For this reason, they are regularly sent out for cleaning to remove adhering germs and dirt, but since they are not sent out for cleaning every day, there is a problem of gradually becoming dirty. In addition, the slippers used in hospitals and companies were hardly cleaned and were not hygienic.

Work clothes worn by civil engineering and construction workers, sportswear, and bodice and armor for kendo and judo absorb a lot of sweat, especially in the summer. You should clean each time you sweat, but since it takes a long time to dry the bodice and armor, it is often used for a long time as it is, and bacteria may propagate and give off a bad odor. There are also 1 fishermen, food processors, and civil engineers.
During the daytime, I am working in boots, so even if the inside gets wet with water or sweat, drying is troublesome, so I often wear it as it is and it is not hygienic as well. Also, those that can be boiled and sterilized such as scissors and razors used in the barber shop are good,
Those made of plastic such as combs and hair brushes could not be boiled and sterilization was troublesome.

[0004]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned drawbacks by simply putting clothes such as a white coat and work clothes, footwear such as slippers and boots, and a container and medical equipment in a locker. It is intended to provide a device capable of efficiently removing bacteria, deodorizing and drying.

[0005]

According to a first aspect of the present invention, there is provided a disinfecting / deodorizing / drying apparatus in which a partition plate is vertically provided inside an adiabatic rocker to provide an irradiation chamber and a duct-like heater installation chamber. Separated, the inner wall of the irradiation chamber is covered with a reflection plate and a door is provided, an irradiation window is provided on the partition plate, and a far-infrared heater is installed in the heater installation room toward this irradiation window. An air outlet is formed in this chamber and a fan is attached to it.At the same time, a suction port is formed on the bottom side of the irradiation chamber.The suction port is connected to the heater installation chamber and the air outlet so that air convection flows through the irradiation chamber. It is characterized in that a flow path is formed.

Further, the invention according to claim 2 is characterized in that a perforated member such as a wire mesh, a lath material or a punching metal is attached to the irradiation window.

[0007]

When a garment such as a white coat or work clothes is processed by the disinfecting and deodorizing drying apparatus of the present invention, the door of the heat insulating locker is opened and the garment is put in the irradiation chamber. When the switch is turned on, the far infrared heater is energized, and far infrared rays having a wavelength of 2 μ to 8 μ are emitted from the heater. The radiated far infrared rays are radiated into the irradiation chamber through an irradiation window of a partition plate formed in front of the far infrared rays through a porous member such as a wire mesh.

The porous member has a function of protecting the clothes from being directly irradiated with a large amount of heat from the far infrared heater, preventing the clothes from being scorched, and diffusely reflecting the far infrared rays. Far-infrared rays are diffusely reflected here, and some of them pass through the openings of the porous member and are irradiated into the irradiation chamber, and are diffusely reflected by the reflecting plate coated on the inner surface of the irradiation chamber and the surface of the clothing to uniformly heat the clothing. I will do it.

Since far infrared rays having a wavelength of 2 to 8 μ are small photon energies, a chemical reaction hardly occurs. When a substance absorbs far infrared rays, molecular vibration of the substance is excited and the temperature rises. In other words, far-infrared rays have an excellent temperature raising effect due to molecular vibrations of substances, and by continuously irradiating these far-infrared rays, bacteria are self-heated to kill or damage, thereby deodorizing and evaporating water. It is made to dry.

The irradiation chamber and the heater installation chamber are separated by a partition plate, a far infrared heater is installed in the installation chamber, and the duct-shaped heater installation chamber communicates with the upper air outlet and the lower suction port, A flow path is formed through which air is convected through the irradiation chamber. Therefore, the high-temperature far-infrared heater is cooled by the air that rises in the heater installation chamber, the heated air is blown from the air outlet toward the irradiation chamber, and it descends while heating the clothes in the irradiation chamber to lower the temperature. The air rises up the heater installation chamber from the suction port again to cool the far infrared heater to prevent this overheating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. In the figure, 1 is a heat insulating locker, which has a heat insulating material 2 attached to the inside of a wall surface.
A partition plate 3 is provided in the heat insulating locker 1 in the vertical direction, and is divided into an irradiation chamber 4 and a duct-shaped heater installation chamber 5. The inner wall surface of the irradiation chamber 4 is covered with a reflection plate 7 such as an aluminum plate, and a door 8 is provided on the front surface so as to be openable and closable.

An irradiation window 9 is opened on the lower side of the partition plate 7, and a wire net 10 is attached thereto. In addition, a far-infrared heater is provided in the heater installation chamber 5 toward the irradiation window 9.
11 are installed. Moreover, a ceiling plate is provided on the upper side of the irradiation chamber 4.
12 is attached, and the outlet 13 is formed here. A fan 15 is attached to the upper space 14 facing the air outlet 13. A suction port 17 is opened in the floor plate 16 of the irradiation chamber 4, and a bottom space 18 therebelow communicates with the heater installation chamber 5 and the upper space 14 in a duct shape. In the figure, 20 is a control device attached to the upper part of the heat insulating locker 1,
Reference numeral 21 is a timer, 22 is a caster attached to the bottom surface of the heat insulating rocker 1, 23 is a hanging pipe horizontally attached to the upper side of the irradiation chamber 4, 24 is a white coat suspended here, and 25 is a slipper.

A case in which the disinfecting and deodorizing / drying apparatus having the above-described configuration is installed in a hospital will be described. The white coat 24 worn by doctors and nurses at the hospital is opened after the medical treatment for one day is completed, and the door 8 of the sterilization / deodorization drying device is opened and hung on the hanging pipe 23 of the irradiation room 4, and the slippers 25 Is placed on the floor board 16. In this way, as shown in Figure 2, white coats 24 and slippers for several people
25 is placed in the irradiation chamber 4.

Next, the timer 21 is set, and at night, the far-infrared heater 11 is supplied with low-cost late-night power to emit far-infrared rays having a wavelength of 2 μ to 8 μ at a heater surface temperature of about 450 ° C. Heated to conditions. As a result, the far-infrared rays emitted from the far-infrared heater 11 are radiated into the irradiation chamber 4 through the irradiation window 9 of the partition plate 3 formed in front of the far-infrared ray heater 10 through the wire net 10. At this time, protect the far-infrared heater 11 with a wire mesh 10 so that a large amount of heat is not directly emitted,
Prevents the white coat 24 and slippers 25 from burning and
Far-infrared rays are diffusely reflected by the metal wires forming the wire netting 10. For this reason, the far infrared rays are diffusely reflected by the wire netting 10 and a part of the far infrared rays passes through the netting and is irradiated into the irradiation chamber 4, and as shown by the broken line arrow in FIG. 1, the reflecting plate 7 and the white coat 24 formed of an aluminum plate. The white coat 24 and the slippers 25 are uniformly heated by being diffusely reflected on the surface.

Further, the temperature inside the chamber is raised to about 60 ° C. in about 20 minutes at once by the control device 20, and the white coat 24 and the slippers 25 are heated to the state before the fibers are burnt, and the temperature is rapidly raised to the required temperature for sterilization. The first stage of heating is performed. After that, the temperature of the far-infrared heater 11 is lowered to about 250 ° C to 300 ° C, the wavelength of 2μ to 8μ is continuously emitted, and the temperature in the refrigerator is kept at about 40 ° C.
Enter the second stage of slow heating, which is set to ~ 55 ° C. In this case, a temperature sensor (not shown) detects the temperature inside the chamber and the temperature of the far-infrared heater 11, and while the control device 20 repeatedly turns on and off the far-infrared heater 11, the far-infrared ray of 2 to 8 μ is constantly emitted in a slow heating state. It is supposed to be done.

Far-infrared rays having a wavelength of 2-8 μm have a small photon energy, so that a chemical reaction hardly takes place. When a substance absorbs far-infrared rays, molecular vibration of the substance is excited to raise the temperature. That is, when water is sufficiently contained in a substance, it is heated at a high temperature to rapidly raise the temperature of water, and the temperature is slowly raised by low temperature heating before the protein etc. of the substance is denatured and becomes "burnt". By performing the control method of switching to, it is possible to save the startup time to the required temperature for sterilization and to perform effective heating. In other words, far-infrared rays have an excellent temperature raising effect due to molecular vibrations of substances, and by continuously irradiating this far-infrared rays with the temperature inside the chamber kept low, bacteria are self-heated to kill or damage, This deodorizes and evaporates water to dry it.

In this case, heating by heat conduction without irradiation of far infrared rays requires heating at a high temperature for a long time,
There is a problem that fibers such as clothes are burnt and burnt. In addition, ultraviolet rays of the same electromagnetic wave have been proven to have a bactericidal effect, but the effect is only on the surface, and unlike the far infrared rays, it does not penetrate deeply into the interior and heat itself, so many white coats
24 cannot be placed in a locker for sterilization and the equipment is expensive. On the other hand, according to the present invention, the far infrared rays are diffusely reflected by the wire netting 10, and a part of the far infrared rays passes through the net and diffusely reflects on the surface of the reflector 7 or the white robe 24 provided in the irradiation chamber 4, while the white robe 24 or The slipper 25 can be heated uniformly.

Further, as shown in FIG. 1, the irradiation chamber 4 and the heater installation chamber 5 are separated by a partition plate 3, a far infrared heater 11 is installed inside the partition plate 3, and an air outlet 13 formed in a ceiling plate 12,
A suction port 17 formed in the floor plate 16 is communicated with each other, and a duct-shaped flow path for convection of air is formed between the heater installation chamber 5 and the irradiation chamber 4. Therefore, the high-temperature far-infrared heater 11 is cooled by the air rising in the heater installation chamber 5, and the heated air is directed downward from the air outlet 13 toward the irradiation chamber 4 by the fan 15 provided in the upper space 14. Are forced to be blown out, and the white coat 24 and the slippers 25 in the irradiation chamber 4 are heated and descend. Further, the air whose temperature has dropped here is sucked into the bottom space 18 from the suction port 17, and this raises the heater installation chamber 5 again to cool the far infrared heater 11 to prevent this overheating.

In this way, a flow path for air convection in one direction is formed to constantly cool the far-infrared heater 11, so that overheating can be prevented and at the same time, the white coat 24 and the slippers 25 can be efficiently heated, and at the same time the far-infrared heater 11 can be removed. Infrared rays can be scattered in the irradiation chamber 4 to enhance sterilization, deodorization and drying effects.

In order to confirm the effect of the present invention, 15 white coats to which Pseudomonas aeruginosa and MRSA (Staphylococcus aureus) are adhered 24
Was hung on the suspension pipe 23 in the irradiation chamber 4 and was first rapidly heated for 20 minutes, and then the second stage slow heating for setting the internal temperature to about 46 ° C. was performed for 6 hours. The deodorizing condition of the bacteria was observed. Also, for comparison, when left in a room (Comparative Example 1), when the irradiation window 9 is closed with an iron plate and only hot air is blown for 6 hours without irradiating far infrared rays (Comparative Example 2), and alcohol for disinfection. Colonies (populations) of the number of bacteria were counted under a microscope for each of the cases of immersion in and sterilization (Comparative Example 3), and the results are shown in Table 1. At the same time, 10 pairs of slippers 25 were put in the irradiation chamber 4 and the deodorizing effect was measured by a measuring instrument of Calmore Co., and the Calmore value is shown in the graph of FIG.

[0021]

[Table 1]

From the results in the above table, it was confirmed that the white coat 24 sterilized using the apparatus of the present invention was completely sterilized with Pseudomonas aeruginosa and Staphylococcus aureus in about 6 hours. Moreover, since the temperature inside the chamber was set to about 46 ° C., there was no damage to the fibers such as charring of the white coat 24. Further, when only the hot air was blown and heated without irradiating the far infrared rays of Comparative Example 2, the bactericidal effect was small. Pseudomonas aeruginosa could be killed by alcohol disinfection, but Staphylococcus aureus was not killed sufficiently.

Regarding the deodorizing effect of the slippers 25, the calmore value is 350 or more and the odor value is unpleasant to all people. As shown in FIG. 3, the initial calmore value is 600, and 2 hours have passed. After 4 hours, it started to drop, and after 4 hours, it fell below 200, which is the level that ordinary people do not feel, and after 6 hours, it dropped to the odorless level.

In addition, wet work clothes with a strong fishy odor worn by a fresh fish trader and boots wet with water to the inside were put in the apparatus of the present invention and irradiated with far infrared rays for 6 hours using electric power at midnight.
As a result, the fish odor of the work clothes was completely removed the next morning, and it was in a dry and warm state, and the inside of the boots was also dry and warm, and the work could be started comfortably.

In the above-mentioned embodiments, the case where the invention is applied to clothes such as a white coat and work clothes, and footwear such as slippers and boots is shown. It can also be widely used for sterilizing medical instruments that cannot be sterilized by boiling, such as hair brushes and endoscopes used in hospitals.

In the above embodiment, the ceiling plate 12 is provided and the air outlet 13 is formed there, and the floor plate 16 is provided and the suction port is provided here.
Although the structure in which the 17 is formed is shown, the structure in which the air outlet 13 is provided in the upper part of the partition plate 3 and the suction port 17 is provided in the lower part may be used. Further, in the above-described embodiment, the case where the metal net 10 is used as the porous member attached to the irradiation window 9 is shown, but a structure using a lath material, punching metal, louver, or a net made of ceramic may be used.

[0027]
