DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disinfecting apparatus for an air conditioner which can be used by being attached to an air conditioner of a hospital and effectively preventing nosocomial infection.

[0002]

2. Description of the Related Art Recently, so-called hospital-acquired infections in which hospitalized patients and newborns are infected with MRSA bacteria and the like in hospitals have been regarded as a serious problem. For this reason, as a means for preventing such hospital-acquired infections, generally, only hospitals, clothes, appliances, etc. are disinfected or hand washing is performed.

[0003]

Means for preventing hospital-acquired infections by conventional disinfection treatments are known in hospitals, clothing,
Although it is possible to effectively sterilize pathogens attached to instruments, etc., there is no effective prevention means for pathogens themselves floating in the hospital through the air conditioner,
In this respect, a major problem remains.

[0004] The present invention solves the conventional problems at a glance, and is intended for an air conditioner capable of effectively preventing in-hospital infection by surely removing bacteria bleeding into the hospital through the air conditioner. An object of the present invention is to provide a sterilization apparatus.

[0005]

That is, according to the present invention, an air supply port 2 is formed on one side of a casing 1 which can be freely connected to air supply and exhaust ports 12 and 13 of an air conditioner 11. On the other side, an exhaust port 3 is formed in a communicating manner, and strong acid water which comes into contact with air to be sterilized is sprayed into the casing 1.
Filter constituted by allowed to fall -4a ·
4b .

[0006]

[Function] Air supply port 12 of air conditioner 11 installed in hospital
And attached to the exhaust opening 13, air filter -4a · 4b in can be effectively prevented nosocomial infection by reliably sterilization have to be vented to the hospital through the air conditioner 11.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, in which 1 is a substantially rectangular casing, 2 is an air supply port formed on one side wall of the casing 1, Reference numeral 3 denotes an exhaust port formed on the other side wall to communicate with the air supply port 2, and the air supply / exhaust ports 2.3 are air supply / exhaust ports 12 of an air conditioner 11 described later.
-It has an opening diameter that can be connected to 13.
4a is Ke - disposed Thing 1 have been filters - a, 該Fu
I filter -4a is Ke - showering disposed top wall inner surface of the single 1 - is constituted by allowed to flow down to form - through a pipe 5 strongly acidic water shower. The strong acid water constituting the filter-4a is adjusted to have a pH of 2.5 to 2.7 and an oxidation-reduction potential of +1000 mb or more in order to effectively exert a sterilizing action. 6
Is a pit-shaped water pan formed on the bottom wall of the casing 1;
Reference numeral 7 denotes a drainage tank connected to the water receiving pan 6 through a drainage pipe 8, 9 denotes a shower pipe 5 through a water supply pipe 10.
The strong acid water generator 9 is connected to the tap water, a small amount of electrolyte such as sodium chloride is added to tap water,
The pH is 2.5 to 2. by electrolysis through a diaphragm.
7. It is said to generate strongly acidic water having an oxidation-reduction potential of +1000 mb or more. In addition, 11 is an air conditioner, and 12 and 13 are an air supply port and an exhaust port formed respectively above and below the air conditioner 11.

Next, the operation of the first embodiment configured as described above will be described. First, the air outlet 3 is connected to the air inlet 12 of the air conditioner 11 and attached. Thereafter, the strongly acidic water generator 9 is operated to generate the strongly acidic water, and is sent to the shower pipe 5 via the water supply pipe 10 so that the strongly acidic water is showered into the casing 1. By letting it flow down, filter-4a is formed. Next, the air conditioner 11 is operated, and the outside air is sequentially sucked through the air supply port 2. Then, the outside air sucked from the air supply port 2 becomes the filter-4a.
Gas-liquid contact one after another with the strong acid water that constitutes, and pathogenic bacteria floating in the outside air are sterilized and removed by the strong acid water . Fi sterilized outside air by Le <br/> data -4a, sucked through the exhaust port 3 and the air supply port 12 into the air conditioner 11, after being conditioned reduction, out through the exhaust port 13 Is exhausted towards At this time, since the filter-4a is composed of strongly acidic water, there is no persistence unlike chemicals such as disinfectants, and moreover, it returns to normal water by direct sunlight or contact with organic substances, so it is safe. In addition, the bactericidal action can be suitably performed without causing environmental pollution and the like. Similarly, while sterilized brought successively vapor-liquid contact with the outside air to the filter -4a, and air conditioning of sucking the air conditioner 11, it may allowed to exhaust to the outside.

[0009] Figure 2 shows a second embodiment of the present invention, that the filter -4b is constituted by allowed to flow down the strongly acidic water atomized through the spray nozzle 14, the spray The point where the compressor 16 is connected to the nozzle 14 via the pipe 15 and the water supply pipe 1
The difference from the first embodiment is that the line pump 17 is interposed in the middle of 0, and the other parts are the same, and the same reference numerals indicate the same parts. In the second embodiment configured as described above, the outside air is suctioned from the air supply port 2, and the air is air-conditioned by the air conditioner 11 while being sterilized with the spray-like strong acid water constituting the filter 4b. The air is exhausted to the outside.

In the above embodiment, the air conditioner 11 is connected to the air supply port 12 for mounting. However, the present invention is not limited to this. Good thing. Further, the present invention relates to an air conditioner 1
In addition to the device 1, the device can be attached to another device similar to the device to suitably perform the disinfecting action.

[0011]

According to the present invention, as described above, the case which can be freely connected to the air supply / exhaust ports 12/13 of the air conditioner 11 is described.
An air supply port 2 is formed on one side of the casing 1 and an exhaust port 3 is formed on the other side thereof in a communicating manner.
Spray strong acid water in the air to remove bacteria by contacting with air
Filter-4a · 4 constituted by dropping
b, the air conditioner 11 is attached to the air inlet 12 and the air outlet 13 of the air conditioner 11 installed in the hospital.
1 filter -4a · air is vented in a hospital through
Nosocomial infection can be effectively prevented by surely removing bacteria with 4b . Also, the filter
Since 4a and 4b are composed of strongly acidic water, they have no persistence unlike chemicals such as disinfectants, and return to ordinary water upon contact with direct sunlight or organic matter, so that they are extremely safe only. In addition, the bacteria can be suitably removed without causing environmental pollution or the like.
