Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disinfecting apparatus for sterilizing and disinfecting a room or clothes of a hospital, and in particular, it has a sterilizing effect in every corner and there is no harmful residue after completion, and waiting time is short. The present invention relates to a disinfection device having high durability.

[0002]

2. Description of the Related Art In hospitals and clinics, if germs and pathogens are present in the atmosphere of hospital rooms, ICUs, walls, floors, etc., there is a risk of infecting patients, visitors and medical staff. Enforced. In addition, clothes such as white coats and hats are frequently changed, and these clothes are similarly sterilized and disinfected.

Conventional sterilization and disinfection methods (generally referred to as disinfection hereinafter) include a heating method, a chemical method, and an ultraviolet ray method. The method by heating has an advantage that it can surely disinfect every corner by boiling the clothes, for example, and there is no harmful residue. The method using a drug is, for example, by spraying and applying ethanol, cresol, or the like,
It disinfects large structures such as rooms and the atmosphere inside. The method using ultraviolet rays uses an ultraviolet ray tube or the like which is generally known as a germicidal lamp, and has the advantages of high germicidal power and no harmful residues.

[0004]

The above-mentioned disinfection methods have their respective drawbacks.

The heating method cannot be used for large structures such as rooms. Further, it takes time to raise the temperature, and cooling is required after heating. Therefore, it takes time to complete the disinfection.

In the method using a drug, the drug itself is often a harmful substance and must be removed after being sprayed, but it is difficult to remove by permeating the wall or the like. It takes time to complete this removal. If it is liquid,
Difficult to spread evenly in every corner of the room.

In the method using ultraviolet rays, the shaded area is not sterilized because it has a straight-line property, and many uneven areas such as clothes are not sterilized. In addition, it has a limited reach and is not suitable for room disinfection.

[0008] As described above, the conventional disinfection methods have the advantages and disadvantages such that the disinfection effect does not reach every corner, harmful residues remain, and waiting time is required for disinfection. Moreover, it could not be performed safely and in a short time.

On the other hand, it is conceivable to place the ozone source in the room and fill the room with ozone. Fumigation using ozone not only has a high sterilizing power but also a gas so that it can spread evenly into the room by diffusion and penetrate into clothes. In addition, ozone is relatively easy to collect and decompose even though it is harmful to the human body. For example, ozone can be recovered simply by passing it through a filter, and ozone is naturally decomposed. Therefore, the residue can be easily prevented. However, in this case as well, in order to shorten the disinfection time, a ventilation fan or the like is provided to actively agitate the atmosphere of the room so as to assist the diffusion of ozone from the ozone generation source and the collection by the filter. There is a need.

By the way, ozone has a function of corroding metals and the like, and if the blower fan and the ozone source are placed in a room, they themselves are exposed to ozone. Also, in order to perform efficient disinfection in order to reduce the time, it is necessary to operate the ozone source and the blower fan at the right time. Operation is required, and this automatic operation etc. also exposes the control device to ozone. In order to utilize ozone, the ozone resistance of the device itself must be enhanced.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a disinfecting apparatus which has a sterilizing effect in every corner, has no harmful residue after completion, and has a short waiting time and high durability. To do.

[0012]

To achieve the above object, the present invention provides an ozone generator for generating ozone and a compressor for supplying air to the ozone generator in a container, and at the same time, the ozone generator is provided. An ozone discharge pipe for discharging ozone into the atmosphere is connected to the container, an intake port for sucking air containing ozone from the atmosphere, an exhaust port for discharging air into the atmosphere, and an intake port for exhausting air. A ventilation fan for circulating air in the atmosphere is provided, and an ozone decomposition filter for removing ozone from the air passing through each of the intake and exhaust ports is further provided.

In the disinfection storage, the disinfection device is provided in at least three storage chambers for storing disinfection objects such as clothes, and the disinfection device is stored in one storage chamber to operate the disinfection device. , In another storage room, stop the disinfection device so that the disinfected object can be taken out, and in another storage room, after taking out the disinfected object, leave the disinfection device stopped. In addition, a control device is provided so that an undisinfected object to be disinfected can be input and the disinfection device in each storage chamber is operated alternately.

In this disinfecting storage, a fan for stirring the atmosphere in the storage chamber may be provided in the storage chamber, and ozone decomposing filters may be installed on both sides of the fan.

[0015]

With the configuration of the disinfection device, the ozone generator generates ozone based on the air in the container supplied by the compressor, and the ozone discharge pipe discharges the generated ozone into the atmosphere without leaking it into the container. To do. On the other hand, the air in the atmosphere is taken in from the intake port by the blower fan and discharged from the exhaust port, but a part is supplied to the compressor. Since the inhaled air has passed through the ozone decomposing filter, it does not contain ozone. Therefore, there is no ozone in the container. Also, if the blower fan is stopped as necessary, air will flow in from the intake and exhaust ports due to natural diffusion or intake of the compressor, but the drawn air does not contain ozone because it has passed through the ozone decomposition filter. . Therefore, there is no ozone in the container.

When the ozone generator is stopped and only the blower fan is operated, air is circulated in the atmosphere through the intake and exhaust ports, and ozone is rapidly recovered and decomposed by the ozone decomposition filter.

With the structure of the disinfecting storage, the disinfection is performed by operating the disinfecting device in the storage room storing the disinfection object. Disinfection is achieved by sequentially releasing ozone, recovering and decomposing it. In the meantime, the disinfected object to be disinfected, that is, clothes before use, can be taken out from another storage chamber as needed. On the other hand, an undisinfected object to be disinfected, such as used clothing, can be put into the storage room where all disinfected objects have been taken out, and can be used in the next disinfection operation. If the three storage rooms are operated in alternation, the clothes etc. before use can be taken out and the clothes etc. already used can be put in at any time.

The fans equipped with the ozone decomposing filters on both sides can stir the atmosphere in the storage room, and diffuse the ozone discharged from the disinfecting device to fine parts such as clothes. In addition, disinfection can accelerate the recovery and decomposition of ozone after the release of ozone is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, the disinfecting apparatus 1 of the present invention has a sealed container 2 made of a member having a high corrosion resistance such as stainless steel. An ozone generator 3 that generates ozone and a compressor 4 that supplies air to the ozone generator 3 are housed in the container 2. Ozone generator 3
For this, a device called an ozonizer is used. The ozonizer has a discharge electrode and discharges to ionize oxygen in the air to generate ozone. An ozone emission pipe 5 is connected to the ozone generator 3, the ozone emission pipe 5 is inserted into the outer wall 2a of the container 2, and the insertion portion is sealed. The end 5a of the ozone discharge tube 5 is opened outside the container. The disinfection device 1 is configured so that the ozone generated by the ozone generator 3 does not leak into the container 2 and is discharged into the atmosphere through the ozone discharge pipe 5.

The container 2 is provided with two windows 6. In the illustrated example, the windows 6 are arranged on the side surfaces of the container 2 which are adjacent to each other, but they may be on the opposite side surfaces, on the same side surface, or on the upper surface. A blower fan 7 is provided facing these windows 6. When the two windows 6 are located at a right angle, the blower fan 7 has a suction side 7i and a blower side 7o formed at right angles.
Is used. Window 6 facing suction side 7i of blower fan 7
Is an intake port 8 for sucking air containing ozone from the atmosphere, and a window facing the blowing side 7o of the blowing fan 7 is an exhaust port 9 for discharging air into the atmosphere. The blower fan 7 can circulate air in the atmosphere through the intake and exhaust ports 8 and 9. Further, in this embodiment, the ozone discharge tube 5
The end 5a of the is extended to the outside of the exhaust port 9,
The ozone discharge pipe 5 may be installed at any place in the vicinity of the intake port 8 in an atmosphere where it is not supplied due to the flow of the supply air.

An ozone decomposing filter 10 is attached to each of the intake port 8 and the exhaust port 9. The ozone decomposing filter 10 is composed of a material that adsorbs ozone, or a catalyst that has a function of decomposing ozone, and has a large number of pores to improve the flow of air and to increase the area in contact with air. is there.

Although not shown, a control circuit and a power source for controlling the ozone generator 3, the compressor 4, the blower fan 7 and the like are provided in the container 2.

Next, the operation of the embodiment will be described.

The disinfection device 1 is installed in the room to be disinfected. The target of disinfection may be anywhere such as a hospital room, a hospital room, an examination room, an operating room, an ICU, or a waiting room. It is also possible to enclose only a specific bed with a sheet and fumigate.

In the disinfecting apparatus 1, ozone is first generated by the ozone generator 3 and is discharged into the atmosphere through the ozone discharge pipe 5 (arrow 15). At this time, ozone may be generated and air may be blown at the same time, but ozone is released and decomposition proceeds at the same time, resulting in slow startup. Therefore, first, only ozone is generated. Therefore, the amount of ozone in the atmosphere increases rapidly. That is, as shown in the graph of FIG. 2, there is a difference in the rise of ozone concentration between the case where only ozone is generated (solid line) and the case where simultaneous blowing is performed (broken line).

During this time, not only in the case of simultaneous air blowing but also in the case of only ozone generation, air containing ozone flows into the container 2 from the intake / exhaust ports 8 and 9 by natural diffusion or intake of the compressor 4 (arrow 12). 11), the ozone decomposing filter 10 adsorbs and decomposes ozone, so that there is no ozone in the container 2. Therefore, the ozone generator 3, the compressor 4, the blower fan 7, or the control circuit (not shown) and the power source are protected from ozone without touching it.

When the blower fan 7 is driven, the ozone discharge pipe 5 is opened to the outside of the exhaust port 9, so that it helps diffuse the discharged ozone. Further, when the ozone concentration has already increased near the disinfection device 1, the air is stirred in the atmosphere, so that a high ozone concentration is achieved in every corner.

When the ozone concentration reaches a desired value or after the operation for a predetermined time, the ozone generator 3 is stopped and only the blower fan 7 is operated. Air containing ozone (indicated by a shaded arrow 13) enters the intake port 8 and air from which ozone has been removed through the ozone decomposition filter 10 (white arrow 1).
4). This air is discharged from the exhaust port 9. As a result, air is circulated through the intake and exhaust ports 8 and 9, and ozone in the atmosphere is rapidly collected and decomposed by the ozone decomposition filter 10.

The combination of operation of the ozone generator 3 and the blower fan 7 can be changed appropriately. For example, the ozone concentration can be maintained at an arbitrary concentration by intermittently operating the ozone generator 3 or the blower fan 7. This is advantageous in that the concentration of ozone that can be sterilized differs depending on the type of bacteria and that control is performed according to the size of the room.

Next, a disinfecting storage using the disinfecting apparatus will be described. The disinfecting storage is configured as shown in FIG. The disinfecting storage 31 has three storage chambers 32 (A, B, C).
have. Since the storage chambers 32 have the same configuration, the storage chamber A will be described. The storage chamber 32 is a closed box made of a highly corrosion-resistant member such as stainless steel, and has a door 3
3 is provided. A rod 34 for hanging a hanger or the like is provided in the storage room 32, and clothes 35 such as a white coat, a surgical gown, a hat, and slippers can be stored. The disinfection device 1 described in the above embodiment is provided in the storage room 32. Further, inside the storage chamber 32, a fan 36 that stirs the atmosphere inside the storage chamber 32 is provided. This fan 36 has the ozone decomposition filter 10 on both sides.
Is installed. A display lamp 37 is provided above the storage chamber 32. The display lamp 37 is a display that means "available,""disinfecting,""used," or the like.

The disinfection device 1, the fan 36, and the display lamp 37 provided in each of the three storage chambers 32 are the control device 3.
Controlled by 8. For example, in storage room B, "disinfecting"
Is displayed and the disinfection device 1 is operating. In the storage chamber B, ozone is generated and removed as in the above-described embodiment. "Usable" is displayed in the storage room C, and the disinfection device 1
Has stopped. The user can open the door of the storage room C and take out clothes or the like. In the storage room A, disinfected clothes and the like have already been taken out, and the disinfection device 1 is currently stopped. The user can open the door of the storage room A and store the used clothing 35 and the like.

When the disinfection of the storage room B is completed and the ozone is exhausted, the storage room B becomes "usable", and instead, the storage room A becomes "disinfecting" when the disinfection device 1 starts operating. The storage room C becomes "used". In this way, the control device 1
Operates the disinfection device 1 in each storage room 32 (A, B, C) in alternation. As a result, the waiting time for disinfection is eliminated, and disinfected clothes can be obtained at any time.

During the disinfection, the fan 36 operates so that the storage chamber is agitated and ozone penetrates into the details such as clothes. Moreover, after the release of ozone is stopped, the recovery and decomposition of ozone are promoted. Therefore, the time required for sterilization can be shortened.

Although the container 2 and the storage chamber 32 are made of stainless steel in the embodiments, they may be made of ozone-resistant plastic or coated.

[0036]

The present invention exhibits the following excellent effects.

(1) Since the sterilizing effect reaches every corner, highly reliable sterilization is achieved.

(2) It is safe with no harmful residue after completion.

(3) Since the ozone concentration is rapidly raised by the ozone generator, and the stirring and the ozone recovery are positively performed by the blower fan, the waiting time becomes short and there is no problem in medical work.

(4) Since ozone does not enter the container, the equipment in the container is protected from ozone and has good durability.

(5) By using the disinfecting hangar, clothes can be disinfected on the spot, which is simple and efficient, and a small number of clothes can be repeatedly used.
